Background Mental ill health is the most frequent cause of long-term sickness absence and disability retirement in Denmark. Some instances of mental ill health might be due to long working hours. A recent large cross-sectional study of a general working population in Norway found that not only “very much overtime”, but also “moderate overtime” (41-48 work hours/week) was significantly associated with increased levels of both anxiety and depression. These findings have not been sufficiently confirmed in longitudinal studies. Objective The objective of the study is to give a detailed plan for a research project aimed at investigating the possibility of a prospective association between weekly working hours and use of psychotropic medicine in the general working population of Denmark. Methods People from the general working population of Denmark have been surveyed, at various occasions in the time period 1995-2010, and interviewed about their work environment. The present study will link interview data from these surveys to national registers covering all inhabitants of Denmark. The participants will be followed for the first occurrence of redeemed prescriptions for psychotropic medicine. Poisson regression will be used to analyze incidence rates as a function of weekly working hours (32-40; 41-48; > 48 hours/week). The analyses will be controlled for gender, age, sample, shift work, and socioeconomic status. According to our feasibility studies, the statistical power is sufficient and the exposure is stable enough to make the study worth the while. Results The publication of the present study protocol ends the design phase of the project. In the next phase, the questionnaire data will be forwarded to Statistics Denmark where they will be linked to data on deaths, migrations, socioeconomic status, and redeemed prescriptions for psychotropic medication. We expect the analysis to be completed by the end of 2014 and the results to be published mid 2015. Conclusions The proposed project will be free from hindsight bias, since all hypotheses and statistical models are completely defined, peer-reviewed, and published before we link the exposure data to the outcome data. The results of the project will indicate to what extent and in what direction the national burden of mental ill health in Denmark has been influenced by long working hours. PMID:25239125

Background: We investigate whether differences in breast cancer survival in six high-income countries can be explained by differences in stage at diagnosis using routine data from population-based cancer registries. Methods: We analysed the data on 257 362 women diagnosed with breast cancer during 2000–7 and registered in 13 population-based cancer registries in Australia, Canada, Denmark, Norway, Sweden and the UK. Flexible parametric hazard models were used to estimate net survival and the excess hazard of dying from breast cancer up to 3 years after diagnosis. Results: Age-standardised 3-year net survival was 87–89% in the UK and Denmark, and 91–94% in the other four countries. Stage at diagnosis was relatively advanced in Denmark: only 30% of women had Tumour, Nodes, Metastasis (TNM) stage I disease, compared with 42–45% elsewhere. Women in the UK had low survival for TNM stage III–IV disease compared with other countries. Conclusion: International differences in breast cancer survival are partly explained by differences in stage at diagnosis, and partly by differences in stage-specific survival. Low overall survival arises if the stage distribution is adverse (e.g. Denmark) but stage-specific survival is normal; or if the stage distribution is typical but stage-specific survival is low (e.g. UK). International differences in staging diagnostics and stage-specific cancer therapies should be investigated. PMID:23449362

Spatial variability of drinking water iodine in Denmark: implications for future policy making

The iodine-an essential component of human thyroid hormones-is provided to our organisms naturally from the food and water and/or is added artificially to the diet. One of the major natural contributors to the dietary iodine intake in Denmark is the drinking water. Both insufficient or excessive iodine intake can cause health problems however the attention falls mainly on the iodine deficiency (ID). Denmark is classified to have mild ID, which is based on sub-national data only. On a bigger scale, in Europe, about 40% of the general population is estimated to suffer from insufficient iodine intake (based on recent update on the iodine status worldwide). A mandatory addition of iodine to the salt was introduced in 2001 in Denmark to address the population's mild deficiency. One of the components of the Danish monitoring program investigating the effect of the salt iodizing (DanThyr) was based on the geographical variation of drinking water iodine levels. More specifically, the location of the two DanThyr cohort studies was chosen to reflect the low concentrations in the western part of Denmark and higher concentration in the eastern part. However, the knowledge about the spatial variability of iodine in Danish ground- and drinking water at that time was quite limited and misrepresentation of the natural variability is suspected. The presented sampling campaign was completed in 2013, and includes 144 waterworks with annual abstraction of about 175 mio m3 groundwater (~45% of the total groundwater abstraction by all active public and private Danish waterworks). The results show a surprisingly complex spatial pattern concerning both the iodine concentrations and speciation. By estimating the dietary iodine intake from water and comparing it to the WHO recommendations, it becomes possible to recognize potentially deficient/excessive geographical areas. Moreover, it is demonstrated that drinking water iodine levels (major dietary iodine contributor in Denmark) can be used as a proxy for the ID status of the population in countries such Denmark, where there is no recent nationwide survey or monitoring program following up the population's iodine status on a national level. Not only can the outcome of this project facilitate the design of future epidemiological studies, but also support policy making in the area of ID prevention and water management as it fills a knowledge gap for drinking water iodine speciation and variation in connection to both spatial distribution and human health.

The prevalence of type 2 diabetes is increased in polycystic ovary syndrome (PCOS), but the prevalence of other diseases is not clarified. We aimed to investigate morbidity and medicine prescriptions in PCOS. A National Register-based study. Patients with PCOS (PCOS Denmark and an embedded cohort; PCOS Odense University Hospital (OUH)) and one control population. Premenopausal women with PCOS underwent clinical and biochemical examination (PCOS OUH, n=1217). PCOS Denmark (n=19 199) included women with PCOS in the Danish National Patient Register. Three age-matched controls were included per patient (n=57 483). Diagnosis codes and filled prescriptions. The mean (range) age of the PCOS Denmark group and controls was 30.6 (12-60) years. Patients in PCOS Denmark had higher Charlson index, higher prevalence of diabetes, dyslipidemia, and hypertension than controls. PCOS was associated with a two times increased risk of stroke and thrombosis, whereas the risk of other cardiovascular diseases was not increased. Thyroid disease, asthma, migraine, and depression were more prevalent in PCOS Denmark vs controls, whereas fractures were rarer. Infertility was increased in patients compared with controls, but the mean number of births was higher in PCOS. Medicine prescriptions within all diagnosis areas were significantly higher in PCOS patients than in controls.In PCOS OUH, polycystic ovaries (PCO) and irregular menses were associated with a more adverse metabolic risk profile, but individual Rotterdam criteria were not associated with cardiometabolic diagnoses. Cardiometabolic and psychiatric morbidity were significantly increased in a Danish population with PCOS. Medical diseases are frequent also in young patients with PCOS. © 2015 European Society of Endocrinology.

In Western countries, black and Asian dialysis patients experience better survival compared with white patients. The aim of this study is to compare the survival of native Danish dialysis patients with that of dialysis patients originating from other countries and to explore the association between the duration of residence in Denmark before the start of dialysis and the mortality on dialysis. We performed a population-wide national cohort study of incident chronic dialysis patients in Denmark (≥18 years old) who started dialysis between 1995 and 2010. In total, 8459 patients were native Danes, 344 originated from other Western countries, 79 from North Africa or West Asia, 173 from South or South-East Asia and 54 from sub-Saharan Africa. Native Danes were more likely to die on dialysis compared with the other groups (crude incidence rates for mortality: 234, 166, 96, 110 and 53 per 1000 person-years, respectively). Native Danes had greater hazard ratios (HRs) for mortality compared with the other groups {HRs for mortality adjusted for sociodemographic and clinical characteristics: 1.32 [95% confidence interval (CI) 1.14-1.54]; 2.22 [95% CI 1.51-3.23]; 1.79 [95% CI 1.41-2.27]; 2.00 [95% CI 1.10-3.57], respectively}. Compared with native Danes, adjusted HRs for mortality for Western immigrants living in Denmark for ≤10 years, >10 to ≤20 years and >20 years were 0.44 (95% CI 0.27-0.71), 0.56 (95% CI 0.39-0.82) and 0.86 (95% CI 0.70-1.04), respectively. For non-Western immigrants, these HRs were 0.42 (95% CI 0.27-0.67), 0.52 (95% CI 0.33-0.80) and 0.48 (95% CI 0.35-0.66), respectively. Incident chronic dialysis patients in Denmark originating from countries other than Denmark have a better survival compared with native Danes. For Western immigrants, this survival benefit declines among those who have lived in Denmark longer. For non-Western immigrants, the survival benefit largely remains over time. © The Author 2015.

In Denmark, age-related macular degeneration (AMD) is the most common cause of blindness. To better understand current and future challenges, we estimated and projected the annual number of patients with neovascular AMD and geographic atrophy in Denmark from 2016 to 2060. Detailed age- and gender-stratified prevalence estimates of neovascular AMD and geographic atrophy in a Scandinavian population were identified and applied to age- and gender-stratified population numbers provided by Statistics Denmark. Prevalence estimates were calculated for each year from 2016 to 2060. Future forecasts were provided by Statistics Denmark and based on calculations by the Danish Institute for Economic Modelling and Forecasting. We estimated that there are currently ~30,000 patients with neovascular AMD and ~21,000 patients with geographic atrophy in Denmark. The majority of these patients are persons aged ≥ 85 years. For neovascular AMD, the number of patients will grow to ~33,000 in 2020, ~58,000 in 2040 and ~72,000 in 2060. For geographic atrophy, the number of patients will grow to ~23,000 in 2020, ~41,000 in 2040, and ~50,000 in 2060. We expect a steady growth in the prevalence of neovascular AMD and geographic atrophy in Denmark due to an ageing population. These numbers emphasise the importance of disease prevention, careful planning of health service activities and continuing research. none. not relevant.

Incidence rates of cutaneous malignant melanoma (CMM) have been increasing markedly worldwide. The ongoing debate about possible overdiagnosis remains unresolved. To determine the population-based incidence of CMM in Denmark between 1978 and 2007 and to analyse sex-, site- and extent of disease-specific changes in incidence rates of CMM over time. We used the virtually complete nationwide Danish Cancer Register in this population-based study, which contains data on 25,851 cases reported in Denmark between 1978 and 2007. We calculated age-standardized (world standard population) incidence rates per 100,000 person-years and age-specific rates. The age-standardized incidence rates increased from 6·5 to 14·4 among men and from 8·6 to 18·9 among women. During the last 5 years of the study period, a sudden marked increase was seen in women of all ages and in men aged 65 years or older. The most marked site-specific change was in the incidence of melanoma on the trunk in both men and women. An increase in the rates of disease with regional spread was seen during the last 10 years of observation. The incidence rate of CMM more than doubled in Denmark between 1978 and 2007. The increases in both site-specific incidence rates and CMM with regional spread suggest an association with risk behaviour, such as intermittent sun exposure, although possible overdiagnosis must be taken into account in evaluating the implications of the increase. © 2011 The Authors.

Urinary incontinence (UI) is a prevalent condition that interferes with women's health-related quality of life. Prevalence rates from earlier studies are wide-ranging, due to heterogeneity in methodology, definition of UI and the populations included. We aimed to determine the prevalence of UI and associated risk factors in Germany and Denmark using the same methodology, definition and population. A postal survey was conducted in two regions in Germany and Denmark, including 8000 women aged 18+ years. UI was defined as any complaint of involuntary loss of urine. The questionnaire contained socio-demographic questions and the International Consultation on Incontinence Modular Questionnaire Urinary Incontinence Short Form (ICIQ-UI SF). The response rate in Germany and Denmark was 46.2 and 66.6% (p < 0.001) and the prevalence rate of UI was 48.3 and 46.4% (p = 0.188), respectively. Stress urinary incontinence dominated among younger women, and urgency urinary incontinence and mixed urinary incontinence among women 80+ years in Germany and Denmark, respectively. The subgroup of women with body mass index (BMI) ≥35 had the highest prevalence of UI (67.3%). The subgroup of women with BMI <35 were more likely to have stress urinary incontinence, and the subgroup of women with BMI ≥35 were more likely to have mixed urinary incontinence. UI was significantly associated with age as with BMI, vaginal delivery, chronic obstructive pulmonary disease, and having at least one co-morbidity. Prevalence rates in the two regions in Germany and Denmark were similar, despite significantly different response rates. This difference may reflect various attitudes towards answering a questionnaire, but the response rate on questions concerning UI seemed consistent. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Background Indigenous Arctic people suffer from high rates of infectious diseases. However, the burden of central nervous system (CNS) infections is poorly documented. This study aimed to estimate incidence rates and mortality of CNS infections among Inuits and non-Inuits in Greenland and in Denmark. Methods We conducted a nationwide cohort study using the populations of Greenland and Denmark 1990–2012. Information on CNS infection hospitalizations and pathogens was retrieved from national registries and laboratories. Incidence rates were estimated as cases per 100,000 person-years. Incidence rate ratios were calculated using log-linear Poisson-regression. Mortality was estimated using Kaplan-Meier curves and Log Rank test. Results The incidence rate of CNS infections was twice as high in Greenland (35.6 per 100,000 person years) as in Denmark (17.7 per 100,000 person years), but equally high among Inuits in Greenland and Denmark (38.2 and 35.4, respectively). Mortality from CNS infections was 2 fold higher among Inuits (10.5%) than among non-Inuits (4.8%) with a fivefold higher case fatality rate in Inuit toddlers. Conclusion Overall, Inuits living in Greenland and Denmark suffer from twice the rate of CNS infections compared with non-Inuits, and Inuit toddlers carried the highest risk of mortality. Further studies regarding risk factors such as genetic susceptibility, life style and socioeconomic factors are warranted. PMID:28158207

Pain is believed to be undertreated in patients with dementia; however, no larger studies have been conducted. The aim was to investigate prevalent use of opioids in elderly with and without dementia in the entire elderly population of Denmark. A register-based cross-sectional study in the entire elderly (≥65 years) population in 2010 was conducted. Opioid use among elderly with dementia (N = 35,455) was compared with elderly without (N = 870,645), taking age, sex, comorbidity, and living status into account. Nursing home residents (NHRs) used opioids most frequently (41%), followed by home-living patients with dementia (27.5%) and home-living patients without dementia (16.9%). Buprenorphine and fentanyl (primarily patches) were commonly used among NHRs (18.7%) and home-living patients with dementia (10.7%) but less often by home-living patients without dementia (2.4%). Opioid use in the elderly Danish population was frequent but particularly in patients with dementia and NHR, which may challenge patient safety and needs further investigation.

Reference intervals are crucial tools aiding clinicians when making medical decisions. However, for children such values often are lacking or incomplete. The present study combines data from separate pediatric reference interval studies of Denmark and Sweden in order to increase sample size and to include also pre-school children who were lacking in the Danish study. Results from two separate studies including 1988 healthy children and adolescents aged 6 months to 18 years of age were merged and recalculated. Eighteen general clinical chemistry components were measured on Abbott and Roche platforms. To facilitate commutability, the NFKK Reference Serum X was used. Age- and gender-specific pediatric reference intervals were defined by calculating 2.5 and 97.5 percentiles. The data generated are primarily applicable to a Nordic population, but could be used by any laboratory if validated for the local patient population.

External compression headache is defined as a headache caused by an external physical compression applied on the head. It affects about 4% of the general population; however, certain populations (e.g. construction workers and military personnel) with particular needs of headwear or helmet are at higher risk of developing this type of headache. External compression headache is poorly studied in relation to specific populations. This study aimed to investigate the prevalence and pattern of helmet-induced external compression headache among Danish military personnel of the Northern Jutland region in Denmark. Data acquisition was based on a custom-made questionnaire delivered to volunteers who used helmets in the Danish military service and who agreed to participate in this study. The military of the Northern Jutland region of Denmark facilitated recruitment of the participants. The questionnaires were delivered on paper and the collected (anonymous) answers (total 279) were used for further analysis. About 30% of the study participants reported headache in relation to wearing a military helmet. Headache was defined as a pressing pain predominantly in the front of the head with an average intensity of 4 on a visual analogue scale of 0 (no pain) to 10 (worst pain imaginable). It was also found that helmets with different designs influenced both the occurrence of headache and its characteristics. This study is the first to demonstrate the prevalence and pattern of compression headache among military personnel in North Jutland, Denmark. The findings of this study call for further attention to helmet-induced external compression headache and strategies to minimize the burden.

A high-resolution assessment of health impacts from air pollution and related external cost has been conducted for Denmark using the integrated EVA model system. The EVA system is based on the impact-pathway methodology, where the site-specific emissions will result, via atmospheric transport and chemistry, in a concentration distribution, which together with detailed population data, is used to estimate the population-level exposure. Using exposure-response functions and economic valuations, the exposure is transformed into impacts on human health and related external costs. In this study we have used a coupling of two chemistry transport models to calculate the air pollution concentration at different domain and scales; the Danish Eulerian Hemispheric Model (DEHM) to calculate the air pollution levels in the Northern Hemisphere with a resolution down to 5.6 km x 5.6 km and the Urban Background Model (UBM) to further calculate the air pollution in Denmark at 1 km x 1 km resolution using results from DEHM as boundary conditions. Both the emission data as well as the population density has been represented in the model system with the same high resolution. Previous health impact assessments related to air pollution have been made on a lower resolution. In this study, the integrated model system, EVA, has been used to estimate the health impacts and related external cost for Denmark at a 1 km x 1 km resolution. New developments of the integrated model system will be presented as well as the development of health impacts and related external costs in Europe and Denmark over a period of 36 years (1979-2014).

An unknown number of asylum seekers arriving in Denmark have been exposed to torture or have experienced other traumatising events in their country of origin. The health of traumatised asylum seekers, both physically and mentally, is affected upon arrival to Denmark, and time in asylum centres leads to further deterioration in health. One hundred forty-two (N=142) newly arrived asylum seekers were examined at Center Sandholm by Amnesty International Danish Medical Group from the 1st of September until the 31st of December 2007. The asylum seekers came from 33 different countries, primarily representing Afghanistan, Iraq, Iran, Syria, and Chechnya. Of the asylum seekers, 45 percent had been exposed to torture--approximately one-third within the year of arrival to Denmark. Unsystematic blows, personal threats or threats to family, degrading treatment, isolation, and witnessing torture of others were the main torture methods reported. The majority of the asylum seekers had witnessed armed conflict, persecution, and imprisonment. The study showed that physical symptoms were approximately twice as frequent and psychological symptoms were approximately two to three times as frequent among torture survivors as among non-tortured asylum seekers. However, even the health of non-tortured asylum seekers was affected. Among the torture survivors, 63 percent fulfilled the criteria for post-traumatic stress disorder, and 30-40 percent of the torture survivors were depressed, in anguish, anxious, and tearful in comparison to 5-10 percent of the non-tortured asylum seekers. Further, 42 percent of torture survivors had torture-related scars. Torture survivors amid newly arrived asylum seekers are an extremely vulnerable group, hence examination and inquiry about the torture history is extremely important in order to identify this population to initiate the necessary medical treatment and social assistance. Amnesty International Danish Medical group is currently planning a follow-up study of the present population which will focus on changes in health status during their time in Denmark.

Previous studies have shown that cancer incidence is related to a number of individual factors, including socioeconomic status. The aim of this study was to refine the current knowledge about indicators associated with cancer incidence by evaluating the influence of neighbourhood characteristics on breast, prostate and lung cancer incidence in Denmark. All women aged 30-83 years were followed for breast cancer between 2004 and 2008, men between 50 and 83 years were followed for prostate cancer and both sexes between ages 50 and 83 were followed for lung cancer. Registry data obtained from Statistics Denmark included age, sex, availability of breast cancer screening, marital status, education, disposable income and occupational socioeconomic status on the individual level and population density and neighbourhood socioeconomic status (the proportion of unemployed) on the parish level. Frailty modelling with individuals on the first level and parishes on the second level was conducted. A significantly lower HR of breast cancer was found in areas with low population density (HR=0.93; CI 0.88 to 0.99), while neighbourhood unemployment had no effect. Inhabitants of lower unemployment areas had a higher risk of prostate cancer (HR=1.14; CI 1.08 to 1.21) compared with those in higher unemployment areas, whereas population density had no effect. Risk of lung cancer was lower in areas with lowest population density (HR=0.80; CI 0.74 to 0.85) and lowest in areas with lowest unemployment (HR=0.88; CI 0.84 to 0.92). In addition to individual-level factors, characteristics on the neighbourhood level also have an influence on breast, prostate and lung cancer incidence.

OBJECTIVE: To estimate the risk of having a low birthweight infant associated with changes in social, environmental, and genetic factors. DESIGN: Population based, historical cohort study using the Danish medical birth registry and Statistic Denmark's fertility database. SUBJECTS: All women who had a low birthweight infant (< 2500 g) (index birth) and a subsequent liveborn infant (outcome birth) in Denmark between 1980 and 1992 (exposed cohort, n = 11,069) and a random sample of the population who gave birth to an infant weighing > or = 2500 g and to a subsequent liveborn infant (unexposed cohort, n = 10,211). MAIN OUTCOME MEASURES: Risk of having a low birthweight infant in the outcome birth as a function of changes in male partner, area of residence, type of job, and social status between the two births. RESULTS: Women in the exposed cohort showed a high risk (18.5%) of having a subsequent low birthweight infant while women in the unexposed cohort had a risk of 2.8%. After adjustment for initial social status, a decline in social status increased the absolute risk of having a low birthweight infant by about 5% in both cohorts, though this was significant only in the unexposed cohort. Change of male partner did not modify the risk of low birth weight in either cohort. CONCLUSION: Having had a low birthweight infant and a decline in social status are strong risk factors for having a low birthweight infant subsequently. PMID:9420490

To investigate the distribution of antibiotic prescriptions in primary health care among children aged 0-6 years and its association with socioeconomic factors. A cross-sectional study describing antibiotic prescriptions and socioeconomic factors, using different population-based registers from Statistics Denmark. Antibiotic prescriptions in 2012 from primary health care in the Capital Region of Denmark. The population of children aged 0-6 years (n = 139,398) in the Capital Region of Denmark. High use of antibiotics identified by number of antibiotic prescriptions (≥ 3 prescriptions per year) and defined daily doses (DDD). A multinomial logistic regression analysis estimating the association between high antibiotic use and parents' education, employment status, income, child's sex, and ethnic background. Ten percent of children accounted for 25% of the total use DDD. There was a clear tendency that the risk for high antibiotic use increased as parental educational level decreased. The risk for high use was the highest among children of mothers and fathers with basic schooling ≤10 years (OR 1.60, 95% CI 1.29-1.98, and OR 1.60, 95% CI 1.34-1.91, respectively). Low income and unemployment were not associated with high antibiotic use. Socioeconomic factors can only partially explain differences in antibiotic use. Further research is needed to clarify the unequal distribution of antibiotic prescribing and the association between high antibiotic use and low educational level. This would provide valuable information in the planning of strategies to promote rational use of antibiotics among children. KEY POINTS The Capital Region of Denmark has the highest rate of antibiotic prescribing in Denmark. Preschool children are among the age groups with the highest use. Ten percent of the children accounted for 25% of the total antibiotic use. Low parental educational level was associated with increased antibiotic use. Parents' income or employment status was not found to be associated with high antibiotic use.

We formally estimate future smoking-attributable mortality up to 2050 for the total national populations of England & Wales, Denmark and the Netherlands, providing an update and extension of the descriptive smoking-epidemic model. We used smoking prevalence and population-level lung cancer mortality data for England & Wales, Denmark and the Netherlands, covering the period 1950-2009. To estimate the future smoking-attributable mortality fraction (SAF) we: (i) project lung cancer mortality by extrapolating age-period-cohort trends, using the observed convergence of smoking prevalence and similarities in past lung cancer mortality between men and women as input; and (ii) add other causes of death attributable to smoking by applying a simplified version of the indirect Peto-Lopez method to the projected lung cancer mortality. The SAF for men in 2009 was 19% (44 872 deaths) in England & Wales, 22% (5861 deaths) in Denmark and 25% (16 385 deaths) in the Netherlands. In our projections, these fractions decline to 6, 12 and 14%, respectively, in 2050. The SAF for women peaked at 14% (38 883 deaths) in 2008 in England & Wales, and is expected to peak in 2028 in Denmark (22%) and in 2033 in the Netherlands (23%). By 2050, a decline to 9, 17 and 19%, respectively, is foreseen. Different indirect estimation methods of the SAF in 2050 yield a range of 1-8% (England & Wales), 8-13% (Denmark) and 11-16% (the Netherlands) for men, and 7-16, 12-26 and 13-31% for women. From northern European data we project that smoking-attributable mortality will remain important for the future, especially for women. Whereas substantial differences between countries remain, the age-specific evolution of smoking-attributable mortality remains similar across countries and between sexes. © 2014 Society for the Study of Addiction.

Work injuries among migrant workers in Denmark.

Biering, Karin; Lander, Flemming; Rasmussen, Kurt

2017-03-01

Work migration into Denmark has increased during the recent decades, especially after the enlargement of the European Union (EU) in 2004. Whether or not migrant workers experience more work injuries than the native workforce has been debated and results are conflicting, most likely due to methodological difficulties and cultural disparities. We set out to meet these challenges using population-based work injury registers, targeting a specific and representative region in Denmark. This population-based study used data on work injuries from an emergency department (ED) and reported injuries from the ED's catchment area to the Danish Working Environment Authority during 11 years. We calculated incidences of work injury for groups of migrant workers compared with native Danes and adjusted incidence rate ratios based on information on the complete working population. The incidences of work injuries among migrant workers from the new EU countries and from the rest of the world were higher compared with Danish workers and workers from the old EU countries and other Western countries. Especially migrants older than 30 years and in low-risk industries were at higher risk. Workers who had migrated recently were at even higher risk. We found increased risk of work injuries among migrant workers. Studying migrants in registers is a methodological challenge as some migrants are not registered, for legal or illegal reasons; thus, only a selected group is studied, but this may most likely underestimate the risk.

Background: There are wide international differences in 1-year cancer survival. The UK and Denmark perform poorly compared with other high-income countries with similar health care systems: Australia, Canada and Sweden have good cancer survival rates, Norway intermediate survival rates. The objective of this study was to examine the pattern of differences in cancer awareness and beliefs across these countries to identify where these might contribute to the pattern of survival. Methods: We carried out a population-based telephone interview survey of 19 079 men and women aged ⩾50 years in Australia, Canada, Denmark, Norway, Sweden and the UK using the Awareness and Beliefs about Cancer measure. Results: Awareness that the risk of cancer increased with age was lower in the UK (14%), Canada (13%) and Australia (16%) but was higher in Denmark (25%), Norway (29%) and Sweden (38%). Symptom awareness was no lower in the UK and Denmark than other countries. Perceived barriers to symptomatic presentation were highest in the UK, in particular being worried about wasting the doctor's time (UK 34% Canada 21% Australia 14% Denmark 12% Norway 11% Sweden 9%). Conclusion: The UK had low awareness of age-related risk and the highest perceived barriers to symptomatic presentation, but symptom awareness in the UK did not differ from other countries. Denmark had higher awareness of age-related risk and few perceived barriers to symptomatic presentation. This suggests that other factors must be involved in explaining Denmark's poor survival rates. In the UK, interventions that address barriers to prompt presentation in primary care should be developed and evaluated. PMID:23370208

United States and Denmark: different approaches to health care and family planning.

The findings of this study suggest that, compared to the United States, Danish health care policies and family planning services delivery systems are, in the aggregate, more conducive to the promotion of effective contraceptive practice, more instrumental in conveying information to high-risk groups, and more successful in reducing the incidence of unintended pregnancies and induced abortions. One of the major reasons for this difference may stem from the positive and nonambivalent climate of public opinion about sexuality in Denmark and the manner in which health care and family planning services are delivered to all segments of the population regardless of age, income, or location of residence. Research in reproductive behavior is greatly facilitated by the existence of automated population registers.

A concordance study of the results of PowerPlex(®) ESI 17 and AmpFℓSTR(®) NGM SElect™ kits obtained from 591 individuals from Somalia (N=198), Denmark (N=199) and Greenland (N=194) was performed. Among 9456 STR types, seven discordant results were found with the two kits: one observed in the D19S433 system in an individual from Denmark and six in the SE33 system in six individuals from Somalia. Sequencing of SE33 in the six samples with discordant results showed G>A transition 15bp downstream of the repeat unit in three of the individuals, and G>A transition 68bp downstream of the repeat unit in the other three individuals. Population data for 16 autosomal STR systems analyzed in 989 individuals from Somalia, Denmark and Greenland are also presented. The highest mean heterozygosity was observed in Danes (82.5%). With the exception of D8S1179 in Danes, no significant deviations from Hardy-Weinberg expectations were observed. Only one pair of systems (D12S391 and D18S51) showed significant allelic association in Greenlanders (after Holm-Šidák correction). A MDS plot drawn from pairwise FST values calculated between 21 populations showed a clear displacement of the Greenlandic population versus the other ones included in the analyses. The highest combined chance of exclusion and power of discrimination was observed for Danes reaching values of 99.9999987% and 1 in 1.8×10(21), respectively. Copyright © 2014 Elsevier Ireland Ltd.

Few etiologic studies of squamous cell carcinoma (SCC) of the penis have been carried out in populations where childhood circumcision is rare. A total of 71 patients with invasive (n=53) or in situ (n=18) penile SCC, 86 prostate cancer controls, and 103 population controls were interviewed in a population-based case-control study in Denmark. For 37 penile SCC patients, tissue samples were PCR examined for human papillomavirus (HPV) DNA. Overall, 65% of PCR-examined penile SCCs were high-risk HPV-positive, most of which (22 of 24; 92%) were due to HPV16. Penile SCC risk was positively associated with measures of early and high sexual activity, including lifetime number of female sex partners, number of female sex partners before age 20, age at first intercourse, penile-oral sex, a history of anogenital warts, and never having used condoms. Histories of phimosis and priapism at least 5 years before diagnosis were also significant risk factors, whereas alcohol abstinence was associated with reduced risk. Our study confirms sexually transmitted HPV16 infection and phimosis as major risk factors for penile SCC and suggests that penile-oral sex may be an important means of viral transmission. The association with priapism was unexpected and needs replication.

Abstract Background The live smallpox and Bacillus Calmette-Guérin (BCG) vaccinations have been associated with better adult survival in both Guinea-Bissau and Denmark. In Guinea-Bissau, human immunodeficiency virus (HIV)-1 became an important cause of death after smallpox vaccination was phased out globally in 1980. We hypothesised that smallpox and BCG vaccinations were associated with a lower prevalence of HIV-1 infection, and we tested this hypothesis in both Guinea-Bissau and Denmark. Methods We conducted 2 studies: (1) a cross-sectional study of HIV infection and vaccination scars in Guinea-Bissau including 1751 individuals and (2) a case-base study with a background population of 46239 individuals in Denmark. In Guinea-Bissau, HIV-1 transmission was almost exclusively sexually transmitted. In Denmark, we excluded intravenous drug users. Data were analyzed using logistic regression. Results Bacillus Calmette-Guérin and/or smallpox vaccination compared with neither of these vaccines was associated with an adjusted odds ratio (aOR) for HIV-1 of 0.62 (95% confidence interval [CI], 0.36–1.07) in Guinea-Bissau and 0.70 (95% CI, 0.43–1.15) in Denmark. We combined the results from both settings in a meta-analysis (aOR = 0.66; 95% CI, 0.46–0.96). Data from Guinea-Bissau indicated a stronger effect of multiple smallpox vaccination scars (aOR = 0.27; 95% CI, 0.10–0.75) as follows: women, aOR = 0.18 (95% CI, 0.05–0.64); men, aOR = 0.52 (95% CI, 0.12–2.33); sex-differential effect, P = .29. Conclusions The studies from Guinea-Bissau and Denmark, 2 very different settings, both suggest that the BCG and smallpox vaccines could be associated with a decreased risk of sexually transmitted HIV-1. It might be informative to pursue this observation and explore possible protective mechanisms as part of the search for an HIV-1 vaccine. PMID:28852677

Increasing incidence of testicular cancer--birth cohort effects.

PubMed

Ekbom, A; Akre, O

1998-01-01

The incidence of testicular cancer is rising in most Western populations. A collaborative study between nine population-based cancer registries in countries around the Baltic Sea was utilized in order to analyze in detail geographic variations and temporal trends in the occurrence of testicular cancer. There were 34,309 cases registered up until 1989 starting in Denmark in 1942 and most recently in Latvia in 1977. From the descriptive epidemiology it was obvious that there was a substantial variation in the age-standardized incidence amounting to about a 10-fold difference between the different countries ranging from 0.8 per 100,000 person-years in Lithuania to 7.6 per 100,000 person-years in Denmark. Previous studies have indicated that this increase is due to birth cohort effects. A more detailed analysis was therefore performed in those six countries with a sufficiently long period of cancer registration; Poland, former East Germany, Norway, Finland, Denmark and Sweden. This analysis showed that birth cohort is a more important determinant of testicular cancer risk than year of diagnosis. In Poland, former East Germany and Finland, there was an increasing risk for all birth cohorts. Among men born in Denmark, Norway or Sweden between 1930 and 1945, this increasing trend in risk was interrupted in these birth cohorts but followed thereafter by an uninterrupted increase by birth cohort. In conclusion, life time exposure to environmental factors which are associated with the incidence of testicular cancer appear to be more related to birth cohort than to year of diagnosis. Because testicular cancer typically occurs at an early age, major etiological factors therefore need to operate early in life, perhaps even in utero.

Despite the concerns about a potential increased risk of skin cancer and lymphoma with the use of topical tacrolimus and pimecrolimus, no population-based studies have given an overview of the use of these drugs in Europe. To assess the use of topical tacrolimus and pimecrolimus in children and adults in Europe. Multicentre database cohort study comprising data from the Netherlands, Denmark, Sweden and the UK. We analysed users of topical tacrolimus and pimecrolimus starting from the date of first availability (between 2002 and 2003) or start establishment of the prescription database in Sweden (2006) through 2011. Use was assessed separately for children (≤ 18 years) and adults. 32,052 children and 104,902 adults were treated with topical tacrolimus, and 32,125 children and 58,280 adults were treated with topical pimecrolimus. The number of users increased rapidly after first availability, especially for topical tacrolimus. Topical tacrolimus was more frequently used in all countries except Denmark. For both drugs, there was a decrease in users after 2004 in the Netherlands and Denmark and after 2005 in the UK, especially among children. This decrease was largest in Denmark. The decrease in the number of users was temporary for topical tacrolimus, while use remained relatively low for topical pimecrolimus. The number of topical tacrolimus and pimecrolimus users increased rapidly after regulatory approval. A transient reduction in topical tacrolimus use and a persistent reduction in topical pimecrolimus use was seen after 2004 in the Netherlands and Denmark and after 2005 in the UK.

The purpose of this study was to describe psychosocial work environment inequalities among wage earners in Spain and Denmark. Data came from the Spanish COPSOQ (ISTAS 21) and the Danish COPSOQ II surveys both performed in 2004-05 and based on national representative samples of employees with a 60% response rate. Study population was 3,359 Danish and 6,685 Spanish women and men. Only identical items from both surveys were included to construct 18 psychosocial scales. Socioeconomic status was categorized according to the European Socioeconomic Classification System. Analysis included ordinal logistic regression and multiple correspondence analysis after categorizing all scales. A relationship between socioeconomic status and psychosocial work environment in both Denmark and Spain was observed, with wider social inequalities in Spain for many scales, describing a strong interaction effect between socioeconomic status and country. Socioeconomic status is related to psychosocial work environment and some adverse psychosocial conditions tend to cluster in lower socioeconomic status groups in both Spain and Denmark. This effect could be modified by a country's characteristics, such as economic and labour market structures, normative regulations and industrial relations including work organization. Hence, preventive strategies to reduce social inequalities in working conditions should consider the combination of actions at the macro and micro levels.

As a consequence of a rapid growth of an ageing population, more people with dementia are expected on the roads. Little is known about whether these people are at increased risk of road traffic-related accidents. Our study aims to investigate the risk of road traffic-related accidents for people aged 65 years or older with a diagnosis of dementia in Denmark. We will conduct a nationwide population-based cohort study consisting of Danish people aged 65 or older living in Denmark as of January 1, 2008. The cohort is followed for 7 years (2008-2014). Individual's personal data are available in Danish registers and can be linked using a unique personal identification number. A person is identified with dementia if the person meets at least one of the following criteria: (1) a diagnosis of the disease in the Danish National Patient Register or in the Danish Psychiatric Central Research Register, and/or (2) at least one dementia diagnosis-related drug prescription registration in the Danish National Prescription Registry. Police-, hospital-, and emergency room-reported road traffic-related accidents occurred within the study follow-up are defined as the study outcome. Cox proportional hazard regression models are used for the main analysis. Our study protocol has 3 phases including data collection, data analysis, and reporting. The first phase of register-based data collection of 853,228 individual's personal information was completed in August, 2016. The next phase is data analysis, which is expected to be finished before December 2016, and thereafter writing publications based on the findings. The study started in January 2016 and will end in December 2018. This study covers the entire elderly population of Denmark, and thereby will avoid selection bias due to nonparticipation and loss to follow-up. Furthermore, this ensures that the study results are reliable and generalizable. However, underreporting of traffic-related accidents may occur, which will limit estimation of absolute risks.

(1) To compare alcohol-attributed disease burden in four Nordic countries 1990-2013, by overall disability-adjusted life years (DALYs) and separated by premature mortality [years of life lost (YLL)] and health loss to non-fatal conditions [years lived with disability (YLD)]; (2) to examine whether changes in alcohol consumption informs alcohol-attributed disease burden; and (3) to compare the distribution of disease burden separated by causes. A comparative risk assessment approach. Sweden, Norway, Denmark and Finland. Male and female populations of each country. Age-standardized DALYs, YLLs and YLDs per 100 000 with 95% uncertainty intervals (UIs). In Finland, with the highest burden over the study period, overall alcohol-attributed DALYs were 1616 per 100 000 in 2013, while in Norway, with the lowest burden, corresponding estimates were 634. DALYs in Denmark were 1246 and in Sweden 788. In Denmark and Finland, changes in consumption generally corresponded to changes in disease burden, but not to the same extent in Sweden and Norway. All countries had a similar disease pattern and the majority of DALYs were due to YLLs (62-76%), mainly from alcohol use disorder, cirrhosis, transport injuries, self-harm and violence. YLDs from alcohol use disorder accounted for 41% and 49% of DALYs in Denmark and Finland compared to 63 and 64% in Norway and Sweden 2013, respectively. Finland and Denmark has a higher alcohol-attributed disease burden than Sweden and Norway in the period 1990-2013. Changes in consumption levels in general corresponded to changes in harm in Finland and Denmark, but not in Sweden and Norway for some years. All countries followed a similar pattern. The majority of disability-adjusted life years were due to premature mortality. Alcohol use disorder by non-fatal conditions accounted for a higher proportion of disability-adjusted life years in Norway and Sweden, compared with Finland and Denmark. © 2016 The Authors.

2014-07-01

Tobacco smoking is among the leading risk factors for chronic disease and early death in developed countries, including Denmark, where smoking causes 14% of the disease burden. In Denmark, many public health interventions, including smoking prevention, are undertaken by the municipalities, but models to estimate potential health effects of local interventions are lacking. The aim of the current study was to model the effects of decreased smoking prevalence in Copenhagen, Denmark. The DYNAMO-HIA model was applied to the population of Copenhagen, by using health survey data and data from Danish population registers. We modelled the effects of four intervention scenarios aimed at different target groups, compared to a reference scenario. The potential effects of each scenario were modelled until 2040. A combined scenario affecting both initiation rates among youth, and cessation and re-initiation rates among adults, which reduced the smoking prevalence to 4% by 2025, would have large beneficial effects on incidence and prevalence of smoking-related diseases and mortality. Health benefits could also be obtained through interventions targeting only cessation or re-initiation rates, whereas an intervention targeting only initiation among youth had marginal effects on morbidity and mortality within the modelled time frame. By modifying the DYNAMO-HIA model, we were able to estimate the potential health effects of four interventions to reduce smoking prevalence in the population of Copenhagen. The effect of the interventions on future public health depended on population subgroup(s) targeted, duration of implementation and intervention reach. © 2014 the Nordic Societies of Public Health.

Despite extensive research on individual diseases, population-based knowledge about reasons for acute medical admissions remains limited. Our aim was to examine primary diagnoses, Charlson Comorbidity Index (CCI) score, age, and gender among patients admitted acutely to medical departments in Denmark. In this population-based observational study, 264,265 acute medical patients admitted during 2010 were identified in the Danish National Registry of Patients (DNRP), covering all hospitals in Denmark. Reasons for acute admissions were assessed by primary diagnoses, grouped according to the International Classification of Diseases 10th edition. Additionally, the CCI score, age and gender were presented according to each diagnostic group. Two-thirds of the patients had one of the four following reasons for admission: cardiovascular diseases (19.3%), non-specific Z-diagnoses ("Factors influencing health status and contact with health services") (16.9%), infectious diseases (15.5%), and non-specific R-diagnoses ("Symptoms and abnormal findings, not elsewhere classified") (11.8%). In total, 45% of the patients had a CCI score of one or more and there was a considerable overlap between the patients' chronic diseases and the reason for admission. The median age of the study population was 64 years (IQR 47-77 years), ranging from 46 years (IQR 27-66) for injury and poisoning to 74 years (IQR 60-83) for hematological diseases. Gender representation varied considerably within the diagnostic groups, for example with male predominance in mental disorders (59.0%) and female predominance in diseases of the musculoskeletal system (57.8%). Our study identifies that acute medical patients often present with non-specific symptoms or complications related to their chronic diseases.

To evaluate the influence of two different dental care systems on dental status, taking into account relevant socio-economic factors. Questionnaire studies on randomly sampled subjects in Denmark and Sweden using questionnaire forms as identical as possible with regard to the different languages. The studies were performed late in 1998 in both countries. Questionnaires were sent to 1,175 subjects aged 45-69 years in Denmark (response rate 73%) and to 1,001 subjects aged 55-79 years in Sweden (response rate 67%). Questions about dental status and about socioeconomic factors and attitudes toward dental care were included. In logistic regression models, various dichotomies of dental conditions were used as dependent variables. State (Denmark vs. Sweden) was used as an independent variable together with socioeconomic factors and attitudes. There were great differences between the countries in dental status. In the regression model with 'wearing removable denture(s)' as the dependent variable, state was the strongest predictor with an OR of above 4.1 for Denmark compared to Sweden. much stronger than variables such as age, income, education and residence. The results indicate that the Swedish dental care system has been superior to the Danish one regarding dental status in middle aged and older populations in these two countries.

This study examined changes in the educational gradients in neonatal and postneonatal mortality over a 20-year period in the four largest Nordic countries. The study populations were all live-born singleton infants with gestational age of at least 22 weeks from 1981 to 2000 (Finland 1987-2000). Information on births and infant deaths from the Medical Birth Registries was linked to information from census statistics. Numbers of eligible live-births were: Denmark 1 179 831, Finland 834 299 (1987-2000), Norway 1 017 168 and Sweden 1 971 645. Differences in mortality between education groups were estimated as risk differences (RD), relative risks (RR) and index of inequality ratio (RII). Overall, rates of infant mortality were in Denmark 5.9 per 1000 live-births, in Finland 4.2 (1987-2000), in Norway 5.3 and in Sweden 4.7. Overall the mortality decreased in all educational groups, and the educational level increased in the study period. The time-trends differed between neonatal and postneonatal death. For neonatal death, both the absolute and relative educational differences decreased in Finland and Sweden, increased in Denmark, whereas in Norway a decrease in absolute differences and a slight increase in relative differences occurred. For postneonatal death, the relative educational differences increased in all countries, whereas the absolute differences decreased. All educational groups experienced a decline in infant mortality during the period under study. Still, the inverse association between maternal education and RR of postneonatal death has become more pronounced in all Nordic countries.

New hypotheses regarding the Danish health puzzle.

Nordic welfare states have achieved admirable population health profiles as a result of public policies that provide economic and social security across the life course. Denmark has been an exception to this rule, as its life expectancies and infant mortality rates since the mid-1970s have lagged behind the other Nordic nations and, in the case of life expectancy, behind most Organisation for Economic Co-operation and Development nations. In this review paper, we identify a number of new hypotheses for why this may be the case. These hypotheses concern the health effects of neo-liberal restructuring of the economy and its institutions, the institution of flexi-security in Denmark's labour market and the influence of Denmark's tobacco and alcohol industries. Also of note is that Denmark experienced higher unemployment rates during its initial period of health stagnation, as well as its treatment of non-Western immigrants and high wealth inequality and, until recently, the fact that Denmark did not systematically address the issue of health inequalities. These hypotheses may serve as covering explanations for the usually provided accounts of elevated behavioural risks and psychosocial stress as being responsible for Denmark's health profile.

There are several reports of familial testicular cancer in the literature but few systematic attempts have been made to estimate the risk of testicular cancer in first-degree relatives of patients with this neoplasm, and the risk remains to be fully assessed in population-based studies. By means of data from the Danish Cancer Registry, we identified all testicular cancer patients (index cases) born and diagnosed during 1950-1993 in Denmark. Their fathers were identified from national registries, as were the brothers of a subcohort of these patients. Familial cancer occurrence was determined through linkage with the cancer registry and compared with the cancer incidence in the general male population in Denmark. The ratio of observed to expected cancers generated the measure used for the relative risk. Fathers of 2,113 index cases with testicular cancer experienced an almost 2-fold risk of developing testicular cancer themselves (RR = 1.96; 95% CI: 1.01-3.43). Overall, the fathers had a decreased relative cancer risk (RR = 0.84; 95% CI: 0.74-0.95) with a significantly decreased risk of cancers of the lung and digestive organs. Brothers of a subcohort of 702 index cases showed a markedly increased risk of testicular cancer (RR = 12.3; 95% CI: 3.3-3 1.5). In conclusion, we documented a significantly increased familial risk of testicular cancer which was relatively more pronounced between brothers than between fathers and sons. These findings support the possible involvement of a genetic component in the aetiology of testicular cancer, but also leave room for a hypothesized influence of in-utero exposures, such as specific maternal hormone levels, that might be shared by brothers.

To quantify the contribution of changes in different risk factors population levels and treatment uptake on the decline in CHD mortality in Denmark from 1991 to 2007 in different socioeconomic groups. We used IMPACTSEC, a previously validated policy model using data from different population registries. All adults aged 25-84 years living in Denmark in 1991 and 2007. Deaths prevented or postponed (DPP). There were approximately 11,000 fewer CHD deaths in Denmark in 2007 than would be expected if the 1991 mortality rates had persisted. Higher mortality rates were observed in the lowest socioeconomic quintile. The highest absolute reduction in CHD mortality was seen in this group but the highest relative reduction was in the most affluent socioeconomic quintile. Overall, the IMPACTSEC model explained nearly two thirds of the decline in. Improved treatments accounted for approximately 25% with the least relative mortality reduction in the most deprived quintile. Risk factor improvements accounted for approximately 40% of the mortality decrease with similar gains across all socio-economic groups. The 36% gap in explaining all DPPs may reflect inaccurate data or risk factors not quantified in the current model. According to the IMPACTSEC model, the largest contribution to the CHD mortality decline in Denmark from 1991 to 2007 was from improvements in risk factors, with similar gains across all socio-economic groups. However, we found a clear socioeconomic trend for the treatment contribution favouring the most affluent groups.

Denmark experienced three waves of the new pandemic influenza A (H1N1)pdm09 from July 2009 to February 2011. The aim of the study was to describe the epidemiology and clinical characteristics of hospitalized patients in a defined population of North Denmark Region with a mixed urban and rural community of 579,000 inhabitants. Review of medical records of all hospitalized patients with confirmed influenza A from July 2009 to February 2011. Two hundred and seventy-three patients were admitted to hospital. The age-related population incidences of hospitalization were as follows: 0-14 years: 111/100,000, 15-64 years: 39/100,000, and ≥ 65 years: 17/100,000. During the first wave (July 2009-August 2009), three patients were admitted - none received treatment in intensive care units (ICUs), during the second wave (October 2009-January 2010), 158 patients were admitted - nine received treatment in ICUs, and during the third wave (December 2010-February 2011), 112 patients were admitted - 25 received treatment in ICUs. Fourteen patients (5%) died within 30 days of diagnosis (median 55 years; range 14-76 years) and additional seven patients (2.6%) died within 365 days (median 25 years; range 1-86 years). Patients hospitalized with pandemic influenza A (H1N1)pdm09 were predominantly children and younger adults, and only a few patients were >65 years. The third wave was the most severe taking the number and percentage of patients admitted to ICUs and 30-day mortality into consideration. We observed that the incidence of hospitalizations as well as clinical severity among younger adults did not decline from the second to the third wave. © 2013 John Wiley & Sons Ltd.

Across several European countries family formation is increasingly postponed. The aims of the study were to investigate the desire for family building and fertility awareness in the UK and Denmark. A population-based internet survey was used among women (n = 1,000) and men (n = 237) from the UK (40%) and Denmark (60%). Data covered socio-demographics, family formation, and awareness of female age-related fertility. Data analysis used descriptive statistics and logistic regression analysis for studying associations between low fertility awareness and desired family formation. The majority of all participants desired two or three children. Two-thirds of the childless participants desired a first child at 30+ years, and one-fifth of the women and one-third of the men desired a last child at age 40. Overall, 83% of women and 73% of men were aware that female fertility starts to decline around 25-30 years. Men had significantly lower fertility awareness. Women who underestimated the impact of age on female fertility were significantly more likely to have a desire or attempted their first child at a higher age. Even though the majority were aware of the age-related decrease in female fertility, most desired having children at an age when female fertility has declined. Women who were not sufficiently aware of the impact of advanced age were significantly more likely to have their first child at a higher age. There is a need for developing educational programs for women and men in order to increase the population's knowledge of fertility and risk factors for infertility.

Microorganisms have shaped the evolution of a variety of defense mechanisms against pathogenic infections. Radioactivity modifies bacterial communities and, therefore, bird hosts breeding in contaminated areas are expected to adapt to the new bacterial environment. We tested this hypothesis in populations of barn swallows ( Hirundo rustica) from a gradient of background radiation levels at Chernobyl and uncontaminated controls from Denmark. Investment in defenses against keratinolytic bacteria was measured from feather structure (i.e., susceptibility to degradation) and uropygial secretions. We studied degradability of tail feathers from areas varying in contamination in laboratory experiments using incubation of feathers with a feather-degrading bacterium, Bacillus licheniformis, followed by measurement of the amount of keratin digested. The size of uropygial glands and secretion amounts were quantified, followed by antimicrobial tests against B. licheniformis and quantification of wear of feathers. Feathers of males, but not of females, from highly contaminated areas degraded at a lower rate than those from medium and low contamination areas. However, feathers of both sexes from the Danish populations showed little evidence of degradation. Individual barn swallows from the more contaminated areas of Ukraine produced the largest uropygial secretions with higher antimicrobial activity, although wear of feathers did not differ among males from different populations. In Denmark, swallows produced smaller quantities of uropygial secretion with lower antimicrobial activity, which was similar to swallow populations from uncontaminated areas in Ukraine. Therefore, barn swallows breeding in contaminated areas invested more in all defenses against keratinolytic bacteria than in uncontaminated areas of Ukraine and Denmark, although they had similar levels of feather wear. Strong natural selection exerted by radioactivity may have selected for individuals with higher defense capacity against bacterial infections during the 30 years since the Chernobyl disaster.

During the 1980s and 1990s, there were large social and structural changes within the Nordic countries. Here we examine time changes in risks of preterm birth by maternal educational attainment in Denmark, Finland, Norway and Sweden. Information on gestational age and maternal socio-economic position was obtained from the NorCHASE database, which includes comparable population-based register data of births from Denmark, Finland, Sweden and Norway from 1981 to 2000. The risks of very preterm birth (<32 gestational weeks) and moderately preterm birth (32-36 gestational weeks) were calculated by maternal educational attainment and analysed in 5-year intervals from 1981 to 2000. Compared with mothers with >12 years of education, mothers with <10 years of education had similarly increased risks of very, and to a lesser extent moderately, preterm birth in all four countries. The educational gradient increased slightly over time in very preterm births in Denmark, while there was a slight narrowing of the gap in Sweden. In moderately preterm births, the educational inequality gap was constant over the study period in Denmark, Norway and Sweden, but narrowed in Finland. The educational gradient in preterm birth remained broadly stable from 1981 to 2000 in all four countries. Consequently, the socio-economic inequalities in preterm birth were not strongly influenced by structural changes during the period.

On 22 July 2011, Anders Breivik killed 77 adults and children in Norway. Having recently documented increases in the incidence of trauma- and stressor-related disorders in Denmark after the 9/11 attacks, we hypothesized that the Breivik attacks-due to their geographic proximity-would be followed by even larger increases in Denmark. Using population-based data from the Danish Psychiatric Central Research Register (1995-2012), we conducted an intervention analysis of the change in the incidence of trauma- and stressor-related disorders after the Breivik attacks. The incidence rate increased by 16% over the following 1½ years after the Breivik attacks, corresponding to 2736 additional cases. In comparison, 9/11 was followed by a 4% increase. We also present evidence of a subsequent surge in incidence stimulated by media attention. This study bolsters previous findings on extra-national consequences of terrorism and indicates that geographic proximity and media coverage may exacerbate effects.

Summary Background Depression and anxiety disorders are highly comorbid conditions and a worldwide disease burden; however, large-scale studies delineating their association are scarce. In this retrospective study, we aimed to assess the effect of severe anxiety disorders on the risk and course of depression. Methods We did a population-based cohort study with prospectively gathered data in Denmark using data from three Danish population registers: The Danish Civil Registration System, the Danish Psychiatric Central Register, and the Danish National Hospital Registry. We selected the cohort from people born in Denmark between Jan 1, 1955, and Dec 31, 2002, who we followed up from Jan 1, 1994, to Dec 31, 2012. The cohort was restricted to individuals with known parents. First, we investigated the effect of specific anxiety diagnoses on risk of single depressive episodes and recurrent depressive disorder. Second, we investigated the effect of comorbid anxiety on risk of readmission for depression, adjusting for sex, age, calendar year, parental age, place at residence at time of birth, and the interaction of age with sex. Findings We included 3 380 059 individuals in our study cohort. The adjusted incidence rate ratio (IRR) for single depressive episodes was 3·0 (95% CI 2·8–3·1, p<0·0001) and for recurrent depressive disorder was 5·0 (4·8–5·2) in patients with severe anxiety disorders compared with the general population. Compared with control individuals, the offspring of parents with anxiety disorders were more likely to be diagnosed with single depressive episodes (1·9, 1·8–2·0) or recurrent depressive disorder (2·1, 1·9–2·2). Comorbid anxiety increased the readmission rates in both patients with single depressive episodes and patients with recurrent depressive disorder. Interpretation Severe anxiety constitutes a significant risk factor for depression. Focusing on specific anxiety disorders might help to identify individuals at risk of depression, thereby providing new insights for prevention and treatment.

Previous studies suggest that religious practice can have a positive effect on mental health, but may also have potential for harm. In Denmark, unique possibilities are available for studying the influence of religious practice on mental health: Denmark is characterized as a secular society and it is possible to follow members of religious societies in nationwide registers. In this study, we follow a cohort of Danish Seventh-day Adventists (SDA) and Baptists in a nationwide psychiatry register and compare the incidence in this cohort with the general population. We followed a cohort of 5,614 SDA and 3,663 Baptists in the Danish Psychiatric Central Register, which contained information on psychiatric hospitalizations from 1970 to 2009. Psychiatric disease incidence in the cohort was compared with that in the general Danish population as standardized incidence ratios and within-cohort comparisons were made with a Cox model. The cohort had decreased incidence of abuse disorders compared to the general population. Furthermore, among Baptists, decreased incidence of unipolar disorders among men and decreased incidence of schizophrenia among women were observed. Surprisingly, we observed an increased incidence rate of unipolar disorder among women. In this nationwide cohort study with 40 years of follow-up, we observed increased incidence rates of unipolar disorders among women and decreased rates of alcohol- and drug-related psychiatric disorders compared to the general Danish population. We have no mechanistic explanation for the increased incidence of unipolar disorders among women, but discuss several hypotheses that could explain this observation.

Objective The present study aims to assess if parental occupational exposure to solvents or heavy metals is associated with risk of testicular germ cell tumors (TGCT) in sons in Denmark. Methods The NORD-TEST Denmark included 3421 cases diagnosed with TGCT at ages 14-49 years in Denmark between 1981 and 2014. Controls (N=14 024) selected from the central population registry were matched to cases on birth year. The Danish Supplementary Pension Fund provided parental occupational information. A job-exposure matrix was used to assign exposures, and conditional logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI). Results The overall analyses showed no significant associations except for paternal exposure to a sub-group of "heavy metal(s) and solvent(s)" (OR 1.50, 95% CI 1.01-2.24). Most fathers in this category had worked in wood related jobs and were assigned exposure to chromium VI and toluene. Other sub-group analyses suggested that maternal exposure to aromatic hydrocarbon were associated with TGCT risk, in sons born in 1970-1979, and to heavy metals (chromium, iron and nickel) in sons born in 1980-1998. Conclusion NORD-TEST Denmark provides no strong support for an association between parental exposures to solvents or heavy metals and TGCT in sons, and only weak support for an association between paternal exposure to chromium and toluene and TGCT risk in sons.

Background This study compares handgrip strength and its association with mortality across studies conducted in Moscow, Denmark, and England. Materials The data collected by the Study of Stress, Aging, and Health in Russia, the Study of Middle-Aged Danish Twins and the Longitudinal Study of Aging Danish Twins, and the English Longitudinal Study of Ageing was utilized. Results Among the male participants, the age-standardized grip strength was 2 kg and 1 kg lower in Russia than in Denmark and in England, respectively. The age-standardized grip strength among the female participants was 1.9 kg and 1.6 kg lower in Russia than in Denmark and in England, respectively. In Moscow, a one-kilogram increase in grip strength was associated with a 4% (hazard ratio [HR] = 0.96, 95% confidence interval [CI]: 0.94, 0.99) reduction in mortality among men and a 10% (HR = 0.90, 95%CI: 0.86, 0.94) among women. Meanwhile, a one-kilogram increase in grip strength was associated with a 6% (HR = 0.94, 95%CI: 0.93, 0.95) and an 8% (HR = 0.92, 95%CI: 0.90, 0.94) decrease in mortality among Danish men and women, respectively, and with a 2% (HR = 0.98, 95%CI: 0.97, 0.99) and a 3% (HR = 0.97, 95%CI: 0.95, 0.98) reduction in mortality among the English men and women, respectively. Conclusion The study suggests that, although absolute grip strength values appear to vary across the Muscovite, Danish, and English samples, the degree to which grip strength is predictive of mortality is comparable across national populations with diverse socioeconomic and health profiles and life expectancy levels.

Aim To quantify the contribution of changes in different risk factors population levels and treatment uptake on the decline in CHD mortality in Denmark from 1991 to 2007 in different socioeconomic groups. Design We used IMPACTSEC, a previously validated policy model using data from different population registries. Participants All adults aged 25–84 years living in Denmark in 1991 and 2007. Main outcome measure Deaths prevented or postponed (DPP). Results There were approximately 11,000 fewer CHD deaths in Denmark in 2007 than would be expected if the 1991 mortality rates had persisted. Higher mortality rates were observed in the lowest socioeconomic quintile. The highest absolute reduction in CHD mortality was seen in this group but the highest relative reduction was in the most affluent socioeconomic quintile. Overall, the IMPACTSEC model explained nearly two thirds of the decline in. Improved treatments accounted for approximately 25% with the least relative mortality reduction in the most deprived quintile. Risk factor improvements accounted for approximately 40% of the mortality decrease with similar gains across all socio-economic groups. The 36% gap in explaining all DPPs may reflect inaccurate data or risk factors not quantified in the current model. Conclusions According to the IMPACTSEC model, the largest contribution to the CHD mortality decline in Denmark from 1991 to 2007 was from improvements in risk factors, with similar gains across all socio-economic groups. However, we found a clear socioeconomic trend for the treatment contribution favouring the most affluent groups. PMID:29672537

2014-10-01

The objective of this study is to estimate the prevalence of energy drink consumption and examine the associations of socio-demographic factors and health behaviour with energy drink consumption among young adults in Denmark. The study is based on a public health survey from 2010 (n = 3923). Multiple logistic regression analyses were used to analyse the association between weekly consumption of energy drink and the potential explanatory factors of interest. In total, 15.8 % of the young adults drink energy drinks on a weekly basis. Men have higher odds of weekly energy drink consumption than women. The study also shows that young age, being employed and having a low educational level are associated with weekly energy drink consumption. According to health behaviour, daily smoking, high amounts of alcohol consumption, alcoholic binge drinking and being overweight are associated with weekly energy drink consumption. Compared with other European countries the prevalence of energy drink consumption is relatively low in Denmark. In Denmark energy drink consumption is typically a male phenomenon and there is a clear social gradient in the prevalence of energy drink consumption where the intake is far more common among people with low levels of education than among people with higher levels of education. This study also shows that there is some kind of 'add on' effect of energy drinks, meaning that people who also use other stimulants-such as alcohol and cigarettes-are more inclined to consume energy drinks. © The Author 2014.

Non-parallel divergence across freshwater and marine three-spined stickleback Gasterosteus aculeatus populations.

2017-07-01

This work investigated whether multiple freshwater populations of three-spined stickleback Gasterosteus aculeatus in different freshwater catchments in the Jutland Peninsula, Denmark, derived from the same marine populations show repeated adaptive responses. A total of 327 G. aculeatus collected at 13 sampling locations were screened for genetic variation using a combination of 70 genes putatively under selection and 26 neutral genes along with a marker linked to the ectodysplasin gene (eda), which is strongly correlated with plate armour morphs in the species. A highly significant genetic differentiation was found that was higher among different freshwater samples than between marine-freshwater samples. Tests for selection between marine and freshwater populations showed a very low degree of parallelism and no single nucleotide polymorphism was detected as outlier in all freshwater-marine pairwise comparisons, including the eda. This suggests that G. aculeatus is not necessarily the prime example of parallel local adaptation suggested in much of the literature and that important exceptions exist (i.e. the Jutland Peninsula). While marine populations in the results described here showed a high phenotype-genotype correlation at eda, a low association was found for most of the freshwater populations. The most extreme case was found in the freshwater Lake Hald where all low-plated phenotypes were either homozygotes for the allele supposed to be associated with completely plated morphs or heterozygotes, but none were homozygotes for the putative low-plated allele. Re-examination of data from seven G. aculeatus studies agrees in showing a high but partial association between phenotype-genotype at eda in G. aculeatus freshwater populations and that mismatches occur everywhere in the European regions studied (higher in some areas, i.e. Denmark). This is independent of the eda marker used. © 2017 The Fisheries Society of the British Isles.

The paper analyses the development of the total number of journal articles indexed in the Medline database published by authors affiliated to Denmark 1989-1998 in medicine compared to the development in the European Union during the same period. The publication analysis is then compared to the citation impact of articles published in the central journals indexed in Science Citation Index (ISI) 1987-1996 through use of the National Science Indicators (NIS, ISI) database. The total number of Danish journal articles has remained relatively constant compared to a 50% increase in the EU as a whole. The number of Danish articles published in central journals, however, has increased by 20% (compared to 27% for the EU) and the number of citations obtained by these articles by 58% (compared to 66% for the EU) in the 1987-1996 period. By population, Denmark ranked third in total number of articles in 1998. In conclusion, Denmark is very active in medical research but neither the quantity nor the quality of Danish medical research has increased at the same rate as the EU average.

We investigated the association between socioeconomic factors and the attainment of treatment goals and pharmacotherapy in patients with type 2 diabetes in Denmark. A cross-sectional population study. The municipality of Naestved, Denmark. We studied 907 patients with type 2 diabetes identified from a random sample of 21,205 Danish citizens. The proportion of patients who were not achieving goals for diabetes care based on their HbA 1c , LDL-cholesterol, blood pressure, and lifestyle, and the proportion of patients who were treated with antihypertensive and cholesterol- and glucose-lowering medication. We investigated the association of the socioeconomic factors such as age, gender, education, occupation, income, and civil status and attainment of treatment goals and pharmacotherapy in logistic regression analyses. We investigated effect modification of cardiovascular disease and kidney disease. Middle age (40-65 years), low education level (i.e. basic schooling), and low household income (i.e. less than 21,400 € per year) were associated with nonattainment of goals for diabetes care. The association of socioeconomic factors with attainment of individual treatment goals varied. Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure. Socioeconomic factors were not associated with treatment goals for hyperglycemia. Socioeconomic factors were inconsistently associated with pharmacotherapy. There was no difference in contacts to general practitioners according to SES. In a country with free access to health care, the socioeconomic factors such as middle age, low education, and low income were associated with nonattainment of goals for diabetes care. KEY POINTS Middle age, low education, and low income were associated with nonattainment of goals for diabetes care, especially for lifestyle goals. Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure. Association of socioeconomic factors with pharmacotherapy was inconsistent.

Studies have shown that malnutrition increases the risk of morbidity, mortality, the length of hospital stay, and costs in the elderly population. Approximately one third of all patients admitted to geriatric wards in Denmark are malnourished according to the Danish Geriatric database. The aim of this study is to describe and examine the sudden increase in deaths due to malnutrition in the elderly population in Denmark from 1999 and, similarly, the sudden decline in malnutrition related deaths in 2007. A descriptive epidemiologic study was performed. All Danes listed in the national death registry who died from malnutrition in the period from 1994 to 2012 are included. The number of deaths from malnutrition increased significantly during the period from 1999 to 2007, especially in the age group 70 years and over. Additionally, we document a surprising similarity between the development in excess mortality from malnutrition in the five Danish regions during the same period. During the period 1999-2007 malnutrition was the direct cause of 340 extra deaths, and probably ten times more registered under other diseases. This development in excess mortality runs parallel in all five Danish regions over time. Copyright © 2016 European Society for Clinical Nutrition and Metabolism. Published by Elsevier Ltd.

Variation in genes involved in alcohol metabolism is associated with drinking patterns worldwide. We compared variation in these genes among the Inuit with published results from the general population of Denmark and, due to the Asian ancestry of the Inuit, with Han Chinese. We analyzed the association between gene variations and drinking patterns among the Inuit. We genotyped 4162 Inuit participants from two population health surveys. Information on drinking patterns was available for 3560. Seven single nucleotide polymorphisms (SNPs) were examined: ADH1B arg48his, ADH1C ile350val, ADH1C arg272gln, ALDH2 glu504lys, ALDH2 5'-UTR A-357G, ALDH1B1 ala86val and ALDH1B1 arg107leu. The allele distribution differed significantly between Inuit and the general population of Denmark. A protective effect on heavy drinking was found for the TT genotype of the ALDH1B1 arg107leu SNP (OR=0.59; 95% CI 0.37-0.92), present in 3% of pure Inuit and 37% of Danes. The ADH1C GG genotype was associated with heavy drinking and a positive CAGE test (OR 1.34; 95% CI 1.05-1.72). It was present in 27% of Inuit and 18% of Danes. The Asian genotype pattern with a high frequency of the ADH1B A allele and an ALDH2 gene coding for an inactive enzyme was not present in Greenland. ADH1C and ALDH1B1 arg107leu SNPs play a role in the shaping of drinking patterns among the Inuit in Greenland. A low frequency of the ALDH1B1 arg107leu TT genotype compared with the general population in Denmark deserves further study. This genotype was protective of heavy drinking among the Inuit.

The aim was to evaluate the incidence, treatment, surgery rate, and anthropometry at diagnosis of children with inflammatory bowel disease (IBD). Patients diagnosed between January 1, 2007 to December 31, 2009 in Eastern Denmark, Funen, and Aarhus were included from a background population of 668,056 children <15 years of age. For evaluation of incidence, treatment, and surgery rate, a subcohort from Eastern Denmark was extracted for comparison with a previously published population-based cohort from the same geographical area (1998-2006). In all, 130 children with IBD: 65 with Crohn's disease (CD), 62 with ulcerative colitis (UC), and three with IBD unclassified (IBDU) were included. The mean incidence rates per 10(6) in 2007-2009 were: IBD: 6.4 (95% confidence interval [CI]: 5.4-7.7), CD: 3.2 (2.5-4.1), UC: 3.1 (2.4-4.0) and IBDU: 0.2 (0.05-0.5). Comparing the two cohorts from Eastern Denmark we found higher incidence rates for IBD (5.0 and 7.2 in 1998-2000 and 2007-2009, respectively, P = 0.02) and CD (2.3 versus 3.3, P = 0.04). Furthermore, we found a significant decrease in surgery rates (15.8/100 person-years versus 4.2, P = 0.02) and an increase in the rate of initiating immunomodulators (IM) within the first year (29.0/100 person-years versus 69.2, P < 0.001). IM use was associated with a trend towards a decreased surgery risk (relative risk [RR] 0.38; 0.15-1.0). Children with CD had poor nutritional status at diagnosis compared with the general pediatric population. Over the past 12 years we found an increase in the incidence of IBD in children, an increasing use of IM, and decreasing 1-year surgery rates. CD patients had poor nutritional status.

To assess the trends in incidence of penile cancer during 1978-2008 and high-grade penile intraepithelial neoplasia (PIN2/3) during 1998-2008 in Denmark. Using two nationwide registries, we estimated age- and period-specific incidence rates. Log-linear Poisson regression analysis was used to estimate average annual percentage change (AAPC) and 95% confidence intervals (CI). We identified 1,488 men with penile cancer and 285 men with PIN2/3. The incidence of penile cancer increased from 1.0 to 1.3 per 100,000 men-years in 1978-1979 to 2006-2008; this represented an AAPC of 0.8% (95% CI: 0.17-1.37). Squamous cell carcinoma (SCC) was the most common histological type (91.7%). The median age at diagnosis was 67 years, and the age-specific incidence rate of penile SCC increased with increasing age. The incidence rate of PIN2/3 increased significantly (0.5 to 0.9 per 100,000 men-years) in 1998-1999 to 2006-2008, and this represented an AAPC of 7.1% (95% CI: 3.30-11.05). The incidence of penile cancer increased in 1978-2008 in Denmark, and the same applied to PIN2/3 in 1998-2008. A high prevalence of human papillomavirus (HPV) and a low circumcision rate in Denmark may partly explain our results.

To examine period-, age- and histology-specific trends in the incidence rate of borderline ovarian tumors in Denmark in 1978-2006. Register-based cohort study. Denmark 1978-2006. 5079 women diagnosed with a borderline ovarian tumor in at least one of two nationwide registries (4312 epithelial tumors and 767 non-epithelial/unspecified tumors). Estimation of overall incidence rates and period-, age- and histology-specific incidence rates. Age-adjustment was done using the World Standard POPULATION. To evaluate incidence trends over time, we estimated average annual percentage change and 95% confidence intervals (CI) using log-linear Poisson models. Age-standardized and age-specific incidence rates and average annual percentage change. The incidence of epithelial borderline ovarian tumors increased from 2.6 to 5.5 per 100,000 women-years between 1978 and 2006, with an average annual percentage change of 2.6% (95% CI: 2.2-3.0). The median age at diagnosis was 52 years. Women 40 years or older had a higher average annual percentage change than women younger than 40 years. Most tumors were mucinous (49.9%) and serous tumors (44.4%). Women with mucinous tumors were younger at diagnosis (50 years) compared with women with serous tumors (53 years). Women with serous tumors had a higher average annual percentage incidence change than women with mucinous tumors. The incidence rate of borderline ovarian tumors increased significantly in Denmark in 1978-2006. In line with results for ovarian cancer, Denmark had a higher incidence rate of borderline ovarian tumors compared with the other Nordic countries in 1978-2006. © 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.

Lyme neuroborreliosis is the most severe clinical manifestation of Lyme borreliosis. In most of Denmark, and also Europe, the overall prevalence of Lyme borreliosis seems to be stabilising. This is not the case on the island of Funen, Denmark, where the number of human Lyme neuroborreliosis cases has markedly declined throughout the last decade. We propose the reason for the decline is a major epidemic among roe deer, killing almost half of their population, resulting in a reduction in the tick population which make it less likely to get a tick bite and therefore to contract Lyme neuroborreliosis. This is the first time such a relationship is described as a naturally occurring phenomenon in Europe. Copyright © 2017 Elsevier GmbH. All rights reserved.

To describe the study population and estimate overall survival of women with a serous "borderline" ovarian tumor (SBT) in Denmark over 25 years relative to the general population. The Danish Pathology Data Bank and the Danish Cancer Registry were used to identify 1487 women diagnosed with SBTs from 1978 to 2002. The histologic slides were collected from Danish pathology departments and reviewed by expert pathologists and classified as SBT/atypical proliferative serous tumor (APST) or noninvasive low-grade serous carcinoma (LGSC). Associated implants were classified as noninvasive or invasive. Medical records were collected from hospital departments and reviewed. Data were analyzed using Kaplan-Meier and relative survival was estimated with follow-up through September 2, 2013. A cohort of 1042 women with a confirmed SBT diagnosis was identified. Women with stage I had an overall survival similar to the overall survival expected from the general population (p=0.3), whereas women with advanced stage disease had a poorer one (p<0.0001). This was evident both in women with noninvasive (p<0.0001) and invasive implants (p<0.0001). Only among women with advanced stage, overall survival of women with SBT/APST (p<0.0001) and noninvasive LGSC (p<0.0001) was poorer than expected from the general population. To date this is the largest nationwide cohort of SBTs where all tumors have been verified by expert pathologists. Only in women with advanced stage SBT, overall survival is poorer than in the general population which applies both to women with noninvasive and invasive implants as well as to women with SBT/APST and noninvasive LGSC.

Background Across several European countries family formation is increasingly postponed. The aims of the study were to investigate the desire for family building and fertility awareness in the UK and Denmark. Methods A population-based internet survey was used among women (n = 1,000) and men (n = 237) from the UK (40%) and Denmark (60%). Data covered socio-demographics, family formation, and awareness of female age-related fertility. Data analysis used descriptive statistics and logistic regression analysis for studying associations between low fertility awareness and desired family formation. Results The majority of all participants desired two or three children. Two-thirds of the childless participants desired a first child at 30+ years, and one-fifth of the women and one-third of the men desired a last child at age 40. Overall, 83% of women and 73% of men were aware that female fertility starts to decline around 25–30 years. Men had significantly lower fertility awareness. Women who underestimated the impact of age on female fertility were significantly more likely to have a desire or attempted their first child at a higher age. Conclusion Even though the majority were aware of the age-related decrease in female fertility, most desired having children at an age when female fertility has declined. Women who were not sufficiently aware of the impact of advanced age were significantly more likely to have their first child at a higher age. There is a need for developing educational programs for women and men in order to increase the population’s knowledge of fertility and risk factors for infertility. PMID:27347691

We aimed to investigate the change in prevalence of overweight and obesity in pregnant Danish women from 2004 to 2012, and investigate whether increasing parity was associated with a change in body mass index (BMI) prevalence. We obtained a population-based cohort from the Danish Medical Birth Registry consisting of all Danish women giving birth in 2004-2012 (n = 572 321). This registry contains information on 99.8% of all births in Denmark. We calculated the overall change in prepregnancy BMI status among pregnant women in Denmark, and a multiple linear regression model with adjustment for several potential confounders was used to examine the change in prepregnancy BMI with increasing parity. In 2004, the prevalence of prepregnancy overweight and obesity (BMI ≥ 25) and obesity alone (BMI ≥ 30) was 31.9 and 11%, respectively. In 2012, the prevalence had reached 34.2 and 12.8%. The mean BMI increased for every additional parity from 23.80 (95% CI 23.77-23.82) in parity group 1 to 26.70 (26.52-26.90) in parity group 5+. A multiple linear regression adjusted for potential confounders showed that women on average gained 0.62 (0.58-0.65) BMI units after every additional birth. This study showed a 7.2% increase in overweight and obesity (BMI ≥ 25) and a 16.4% increase in obesity alone (BMI ≥ 30) for pregnant women in Denmark from 2004 to 2012. In addition, an increase in interpregnancy BMI was seen at every additional delivery, suggesting that obesity is an increasing challenge in obstetrics. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

Educational assortative mating and income inequality in Denmark.

PubMed

Breen, Richard; Andersen, Signe Hald

2012-08-01

Many writers have expressed a concern that growing educational assortative mating will lead to greater inequality between households in their earnings or income. In this article, we examine the relationship between educational assortative mating and income inequality in Denmark between 1987 and 2006. Denmark is widely known for its low level of income inequality, but the Danish case provides a good test of the relationship between educational assortative mating and inequality because although income inequality increased over the period we consider, educational homogamy declined. Using register data on the exact incomes of the whole population, we find that change in assortative mating increased income inequality but that these changes were driven by changes in the educational distributions of men and women rather than in the propensity for people to choose a partner with a given level of education.

Prader-Willi syndrome (PWS) is a rare congenital disease that affects growth, sexual development, cognitive function and behavior. Individuals exhibit food preoccupation and hyperphagia, which may lead to obesity with premature morbidity and mortality. The aim of this work was to evaluate the risk of venous thromboembolisms (VTEs), myocardial infarction, pulmonary hypertension, sleep apnea, depression, anxiety and all-cause mortality among persons with PWS as compared with an age- and sex-matched general-population cohort. All persons diagnosed with PWS (n=155) were identified in the Danish Health Registries; an age- and sex-matched comparison group was selected from the general population of Denmark (n=15 500); diseases of interest were identified through the health registry and cause of death register. Follow-up began on date of birth or first medical record availability through to first occurrence of an outcome of interest; follow-up ceased at emigration from Denmark or end of study. Incidence rates (IRs) were calculated and Cox's proportional hazards models were used to understand the relative risk (RR) of disease. The IRs for VTE among patients with PWS was 144 (60-347) per 100 000 person-years. Risks for VTE events and all-cause mortality were 9.4 times (95% confidence interval (CI): 3.7-23.5) and 11.0 times (95% CI: 5.7-21.1) higher, respectively, for patients with PWS versus the general population. Increased risks were also found individually for deep venous thromboses (DVTs) (RR: 9.1; 95% CI: 3.2-25.2), pulmonary embolisms (RR: 11.0; 95% CI: 1.4-86.9), myocardial infarction (RR: 7.2; 95% CI: 1.7-30.2) and anxiety (RR: 2.8; 95% CI: 1.0-7.5). No cases of pulmonary hypertension, sleep apnea or depressive disorders were identified within this PWS cohort. Multiple cardiovascular and behavioral illnesses are more likely to occur among patients with PWS than within the general population. These increased risks may provide an impetus for enhanced disease prevention, screening, diagnosis and treatment.

Sex-specific impact of socio-economic factors on suicide risk: a population-based case-control study in Denmark.

2010-06-01

Although many authors have investigated the impact of sex on the association between socio-economic status (SES) and suicide, a definite consensus has not yet emerged. Using Danish population registration data including 15 648 suicide deaths of individuals aged 18-65 year during 1981-97 and matched population controls, we investigate the associations of multiple SES factors with suicide risk and explore the sex-specific aspects of these associations. We use conditional logistic regression models to estimate the statistical relationship between SES, sex and suicide. SES, proxied by low income, unskilled blue-collar work, non-specific wage work and unemployment, increases suicide risk more prominently for men than for women. Marital status has a comparable influence on suicide risk in both sexes; parenthood is protective against suicide, and the effect is larger for women. Living in a large city raises suicide risk for women but reduces it for men; residents with a foreign citizenship in Denmark have a lower risk of suicide compared with Danish citizens, but this protection is confined to male immigrants. Our results demonstrate that suicide risk is associated with a range of SES proxies but the strength and/or direction of the association can differ by sex. Risk assessment and, therefore, prevention approaches should take this into consideration.

The aim of this study was to examine the development in incidence rates and the severity of weapon-related physical interpersonal violence in Odense Municipality, Denmark from 1991 to 2009. All victims of physical interpersonal violence with weapon-related injuries treated at the Emergency Department in the 1991-2009 period at Odense University Hospital, Denmark, and/or subjected to medico-legal autopsy at the Institute of Forensic Medicine in the 1991-2009 period at the University of Southern Denmark were included. Incidence rates were estimated following stratification by gender and age. The development in the incident rates was examined. Overall, 2,957 victims were included. The overall incidence rate was 8.5 per 10,000 population/year (14.6 and 2.7 for males and females, respectively). The rates did not change significantly in the study period. Most victims were injured with bottles/glass and blunt weapons (44.8% versus 28.2%), whereas 24% were injured with sharp weapons and 3% with firearms. Most lesions were sustained to the head/neck (56.1%) and to the upper limbs (26.2%). A total of 182 (6.1%) victims had lesions that were considered severe. The mortality rate was 4.8 per 1,000 victims in males and 29.1 per 1,000 victims in females. More than half (57%) of the homicides were caused by lesions due to sharp weapons. Weapon-related injuries are rare in the Odense Municipality. The incidence rate of weapon-related violence did not increase in the study period. Additionally, no evidence of an increased proportion of severe injuries was found. Women had a seven-fold higher mortality than males. none. not relevant.

Several studies suggest a link between electric injuries and neurological diseases, where electric shocks may explain elevated risks for neuronal degeneration and, subsequently, neurological diseases. We conducted a retrospective cohort study on the risk of neurological diseases among people in Denmark who had survived an electric accident in 1968-2008. The cohort included 3,133 people and occurrences of neurological diseases were determined by linkage to the nationwide population-based Danish National Register of Patients. The numbers of cases observed at first hospital contact in the cohort were compared with the respective rates of first hospital contacts for neurological diseases in the general population. We observed significantly increased risks for peripheral nerve diseases (standardized hospitalization ratio (SHR), 1.66; 95% confidence interval (CI), 1.22-2.22), for migraine (SHR, 1.80; 95% CI, 1.23-2.54), for vertigo (SHR, 1.60; 95% CI, 1.22-2.05), and for epilepsy (SHR, 1.45; 95% CI, 1.11-1.85). Only small numbers of cases of other neurological diseases were found, making the risk estimates unstable. These findings suggest an association between a single electric shock and increased risks for peripheral nerve diseases, migraines, vertigo, and epilepsy, but confirmation of these observations is needed.

Nationwide sampling campaign of treated drinking water of groundwater origin was designed and implemented in Denmark in 2013. The main purpose of the sampling was to obtain data on the spatial variation of iodine concentration and speciation in treated drinking water, which was supplied to the majority of the Danish population. This data was to be used in future exposure and epidemiologic studies. The water supply sector (83 companies, owning 144 waterworks throughout Denmark) was involved actively in the planning and implementation process, which reduced significantly the cost and duration of data collection. The dataset resulting from this collaboration covers not only iodine species (I−, IO3−, TI), but also major elements and parameters (pH, electrical conductivity, DOC, TC, TN, F−, Cl−, NO3−, SO42−, Ca2+, Mg2+, K+, Na+) and a long list of trace elements (n = 66). The water samples represent 144 waterworks abstracting about 45% of the annual Danish groundwater abstraction for drinking water purposes, which supply about 2.5 million Danes (45% of all Danish residents). This technical note presents the design, implementation, and limitations of such a sampling design in detail in order (1) to facilitate the future use of this dataset, (2) to inform future replication studies, or (3) to provide an example for other researchers.

Cirrhosis, the prevalence of which is increasing, is a risk factor for osteoporosis and fractures. However, little is known of the actual risk of hip fractures in patients with alcoholic cirrhosis. Using linked primary and secondary care data from the English and Danish nationwide registries, we quantified the hip fracture risk in two national cohorts of patients with alcoholic cirrhosis. We followed 3,706 English and 17,779 Danish patients with a diagnosis of alcoholic cirrhosis, and we identified matched controls from the general populations. We estimated hazard ratios (HR) of hip fracture for patients vs. controls, adjusted for age, sex and comorbidity. The five-year hip fracture risk was raised both in England (2.9% vs. 0.8% for controls) and Denmark (4.6% vs. 0.9% for controls). With confounder adjustment, patients with cirrhosis had fivefold (adjusted HR 5.5; 95% CI 4.3-6.9), and 8.5-fold (adjusted HR 8.5; 95% CI 7.8-9.3) increased rates of hip fracture, in England and Denmark, respectively. This association between alcoholic cirrhosis and risk of hip fracture showed significant interaction with age (p <0.001), being stronger in younger age groups (under 45 years, HR 17.9 and 16.6 for English and Danish patients, respectively) than in patients over 75 years (HR 2.1 and 2.9, respectively). In patients with alcoholic cirrhosis, 30-day mortality following a hip fracture was 11.1% in England and 10.0% in Denmark, giving age-adjusted post-fracture mortality rate ratios of 2.8(95% CI 1.9-3.9) and 2.0(95% CI 1.5-2.7), respectively. Patients with alcoholic cirrhosis have a markedly increased risk of hip fracture and post-hip fracture mortality compared with the general population. These findings support the need for more effort towards fracture prevention in this population, to benefit individuals and reduce the societal burden. Alcoholic cirrhosis creates a large public health burden and is a risk factor for bone fractures. Based on data from England and Denmark, we found that hip fractures occur more than five times more frequently in people with alcoholic cirrhosis than in people without the disease. Additionally, the aftermath of the hip fracture is severe, such that up to 11% of patients with alcoholic cirrhosis die within 30 days after their hip fracture. These results suggest that efforts directed towards fracture prevention in people with alcoholic cirrhosis could be beneficial. Copyright © 2018 European Association for the Study of the Liver.

Social determinants for infant mortality in the Nordic countries, 1980-2001.

Arntzen, Annett; Nybo Andersen, Anne Marie

2004-01-01

Social equity in health is an important goal of public health policies in the Nordic countries. Infant mortality is often used as an indicator of the health of societies, and has decreased substantially in the Nordic welfare states over the past 20 years. To identify social patterns in infant mortality in this context the authors set out to review the existing epidemiological literature on associations between social indicators and infant mortality in Denmark, Finland, Norway, and Sweden during the period 1980-2000. Nordic epidemiological studies in the databases ISI Web of Science, PubMed, and OVID, published between 1980 and 2000 focusing on social indicators of infant, neonatal, and postneonatal mortality, were identified. The selected keywords on social indicators were: education, income, occupation, social factors, socioeconomic status, social position, and social class. Social inequality in infant mortality was reported from Denmark, Finland, Norway, and Sweden, and it was found that these increased during the study period. Post-neonatal mortality showed a stronger association with social indicators than neonatal mortality. Some studies showed that neonatal mortality was associated with social indicators in a non-linear fashion, with high rates of mortality in both the lowest and highest social strata. The pattern differed, however, between countries with Finland and Sweden showing consistently less social inequalities than Denmark and Norway. While the increased inequality shown in most studies was an increase in relative risk, a single study from Denmark demonstrated an absolute increase in infant mortality among children born to less educated women. Social inequalities in infant mortality are observed in all four countries, irrespective of social indicators used in the studies. It is, however, difficult to draw inferences from the comparisons between countries, since different measures of social position and different inclusion criteria are used in the studies. Nordic collaborative analyses of social gradients in infant death are needed, taking advantage of the population-covering registers in longitudinal designs, to explore the mechanisms behind the social patterns in infant mortality.

OBJECTIVE: To assess the usefulness of the general framework of the smoking epidemic. METHODS: We use lung cancer mortality as an indicator for smoking intensity and employ an age-cohort model to accommodate the long-lasting and cumulative effects. RESULTS: Dutch males have higher risks than Danish males, but the risks for the younger cohorts have been declining faster in the Netherlands than in Denmark. Danish women have about twice the risk of Dutch women, and in both countries the risks for the younger cohorts are increasing. The smoking epidemic began at about the same time in Denmark and the Netherlands. Dutch males, however, seem to have smoked more but to have given up smoking more quickly than Danish males. Danish females were quicker to take up smoking than Dutch females. CONCLUSIONS: Within the general framework of the smoking epidemic, differences in timing and levels can produce large differences between countries. For the purposes of assessing smoking-related risks, including projections, the smoking epidemic framework therefore has to be tailored to each study population. PMID:11884970

Objective Prenatal exposure to antiepileptic drugs (AEDs) has been associated with adverse outcomes in the offspring such as congenital malformations and neuropsychiatric disorders. The objective of this study was to investigate whether prenatal exposure to AEDs is also associated with more frequent use of primary healthcare during childhood. Design Population-based cohort study. Setting Nationwide national registers in Denmark. Participants All live-born singletons in Denmark during 1997–2012 identified in the Danish National Patient Register and followed until 31 December 2013 (n=963 010). Information on prenatal exposure to AEDs for maternal indication of epilepsy and other neurological conditions was obtained from the Danish Register of Medicinal Product Statistics. Main outcome measures The primary outcome measure was the number and type of contacts with the general practitioner (GP), excluding routine well-child visits and vaccinations. The secondary outcome measure was specific services provided at the GP contact. The association between prenatal exposure to AEDs and contacts with the GP was estimated by using negative binomial regression adjusting for sex and date of birth of the child, maternal age, cohabitation status, income, education, substance abuse, depression, severe psychiatric disorders and use of antipsychotics, antidepressants and insulin. Results Children exposed prenatally to AEDs (n=4478) had 3% (95% CI 0 to 5%) more GP contacts during the study period than unexposed children. This was primarily accounted for by the number of phone contacts. Within each year of follow-up, exposed children tended to have more contacts than unexposed children, but the differences were small. We found no difference between exposed and unexposed children with regard to specific services provided at the GP contact. For the individual AEDs, we found that exposure to valproate or oxcarbazepine was associated with more GP contacts. Conclusions We found only minor differences between prenatally AED-exposed and unexposed children in the number of GP contacts. PMID:28069620

Bacteremia is associated with high morbidity and mortality. Improving prevention and treatment requires better knowledge of the disease and its prognosis. However, in order to study the entire spectrum of bacteremia patients, we need valid sources of information, prospective data collection, and complete follow-up. In North Denmark Region, all patients diagnosed with bacteremia have been registered in a population-based database since 1981. The information has been recorded prospectively since 1992 and the main variables are: the patient’s unique civil registration number, date of sampling the first positive blood culture, date of admission, clinical department, date of notification of growth, place of acquisition, focus of infection, microbiological species, antibiogram, and empirical antimicrobial treatment. During the time from 1981 to 2008, information on 22,556 cases of bacteremia has been recorded. The civil registration number makes it possible to link the database to other medical databases and thereby build large cohorts with detailed longitudinal data that include hospital histories since 1977, comorbidity data, and complete follow-up of survival. The database is suited for epidemiological research and, presently, approximately 60 studies have been published. Other Danish departments of clinical microbiology have recently started to record the same information and a population base of 2.3 million will be available for future studies. PMID:20865114

The purpose of this study was to investigate the association between mode of delivery and the risk of celiac disease in two large population-based birth cohorts with different prevalence of diagnosed celiac disease. This is an observational register-based cohort study using two independent population cohorts. We used data from administrative registers and health administrative registers from Denmark and Norway and linked the data at the individual level. We included all children who were born in Denmark from January 1, 1995 to December 31, 2010 and all children who were born in Norway from January 1, 2004 to December 31, 2012. We included 1,051,028 children from Denmark. Cesarean sections were registered for 196,512 children (18.9%). Diagnosed celiac disease was registered for 1,395 children (0.13%). We included 537,457 children from Norway. Cesarean sections were registered for 90,128 children (16.8%). Diagnosed celiac disease was registered for 1,919 children (0.35%). We found no association between the mode of delivery and the risk of diagnosed celiac disease. The adjusted odds ratio for celiac disease for children delivered by any type of cesarean section compared to vaginal delivery was 1.11 (95% CI: 0.96-1.29) in the Danish cohort and 0.96 (95% CI: 0.84-1.09) in the Norwegian cohort. The adjusted odds ratio for celiac disease for children delivered by elective cesarean section compared to vaginal delivery was 1.20 (95% CI: 1.00-1.43) in the Danish cohort and 0.96 (95% CI: 0.79-1.17) in the Norwegian cohort. In this large registry-based study, mode of delivery was not associated with an increased risk of diagnosed celiac disease.

Few studies investigate what members of the general population know about individuals with autism. Only one study has previously investigated how beliefs about autism differ from those about other psychiatric disorders. This study surveyed a convenience sample of the general adult population, within the Northern Region of Denmark, about their knowledge, attitudes and beliefs about individuals with autism and schizophrenia. The respondents (N = 440) possessed basic knowledge and were able to differentiate between the two disorders. Schizophrenia was associated with perceived danger (32.8%), while autism was associated with high intelligence (40.1%) and creativity (27.3%). Respondents were more positive towards interacting with individuals with autism (p < 0.001), but desire for social distancing was pronounced for both disorders in more intimate relationships. Significantly, more respondents reported that they would find it difficult and feel ashamed with regard to being diagnosed with schizophrenia (p < 0.001). Conversely, respondents significantly reported being more likely to elaborate on their diagnosis of autism to their colleagues (p < 0.001). Perceived dangerousness decreased the willingness for social interactions, while knowing someone with autism or schizophrenia increased the willingness to socially interact. Misconceptions and stigma must be addressed in order to minimize the social stigma and rejection associated with these disorders and ultimately improve the quality of life and psychological well-being of affected individuals and their families. © The Author(s) 2015.

Sweden and Denmark are neighbouring countries with similarities in culture, healthcare, and economics, yet notable differences in cancer statistics. A crucial component of primary prevention is high awareness of risk factors in the general public. We aimed to determine and compare awareness of risk factors for cancer between a Danish and a Swedish population sample, and to examine whether there are differences in awareness across age groups. Data derive from Module 2 of the International Cancer Benchmarking Partnership. Telephone interviews were conducted with 3000 adults in Denmark and 3070 in Sweden using the Awareness and Beliefs about Cancer measure. Data reported here relate to awareness of 13 prompted risk factors for cancer. Prevalence ratios with 95 % confidence intervals were calculated to examine associations between country, age, and awareness of risk factors. Over 90 % of respondents in both countries recognized smoking, use of sunbeds and ionizing radiation as risk factors for cancer. Lowest awareness (<50 %) was found for HPV-infection, low fruit and vegetable intake and alcohol intake. Swedish respondents reported higher awareness than Danish respondents for ten of the 13 risk factors studied. Respondents from Denmark reported higher awareness only regarding low fruit and vegetable intake and use of sunbeds. Low physical activity was the only risk factor for which there was no difference in awareness between the countries. A decline in awareness was generally seen with increasing age in both countries, but deviating patterns were seen for alcohol intake, red/processed meat, obesity and age 70+. This study supports findings from other European studies that generally demonstrate modest public awareness of many established cancer risk factors. Efforts should be made to improve awareness of the cancer risk factors HPV-infection, low fruit and vegetable intake and alcohol intake, which showed particularly low awareness in both countries. Previous studies indicate that repeated, broad campaigns are successful, and suggest that a multimedia approach is used.

OBJECTIVE: To study trends in multiple pregnancies not explained by changes in maternal age and parity patterns. DESIGN: Trends in population based figures for multiple pregnancies in Denmark studied from complete national records on parity history and vital status. POPULATION: 497,979 Danish women and 803,019 pregnancies, 1980-94. MAIN OUTCOME MEASURES: National rates of multiple pregnancies, infant mortality, and stillbirths controlled for maternal age and parity. Special emphasis on primiparous women > or = 30 years of age, who are most likely to undergo fertility treatment. RESULTS: The national incidence of multiple pregnancies increased 1.7-fold during 1980-94, the increase primarily in 1989-94 and almost exclusively in primiparous women aged > or = 30 years, for whom the adjusted population based twinning rate increased 2.7-fold and the triplet rate 9.1-fold. During 1989-94, the adjusted yearly increase in multiple pregnancies for these women was 19% (95% confidence interval 16% to 21%) and in dizygotic twin pregnancies 25% (21% to 28%). The proportion of multiple births among infant deaths in primiparous women > or = 30 years increased from 11.5% to 26.9% during the study period. The total infant mortality, however, did not increase for these women because of a simultaneous significant decrease in infant mortality among singletons. CONCLUSIONS: A relatively small group of women has drastically changed the overall national rates of multiple pregnancies. The introduction of new treatments to enhance fertility has probably caused these changes and has also affected the otherwise decreasing trend in infant mortality. Consequently, the resources, both economical and otherwise, associated with these treatments go well beyond those invested in specific fertility enhancing treatments. PMID:9080993

The Strengths and Difficulties Questionnaire (SDQ) has been translated into the different Nordic languages between 1996 and 2003. During the past few years, SDQs have been completed for nearly 100,000 children and adolescents in population-based studies as well as in clinical samples. The largest studies have been performed in Norway and Denmark, and in these countries the diagnostic interview DAWBA has also been used in conjunction with the SDQ. In addition to a brief overview of past and ongoing SDQ work in Sweden, Finland, Norway, Denmark, and Iceland, we present scale means and standard deviations from selected community studies with comparable age groups, including parental reports for 7, 9 and 11 year-old children and self-reports of 13 and 15 year-olds. The descriptive statistics suggest that the distributions of SDQ scores are very similar across the Nordic countries. Further collaborative efforts in establishing norms and evaluating the validity of the SDQ as a screening instrument are encouraged.

Simulating the spread of classical swine fever virus between a hypothetical wild-boar population and domestic pig herds in Denmark.

Denmark has no free-range wild-boar population. However, Danish wildlife organizations have suggested that wild boar should be reintroduced into the wild to broaden national biodiversity. Danish pig farmers fear that this would lead to a higher risk of introduction of classical swine fever virus (CSFV), which could have enormous consequences in terms of loss of pork exports. We conducted a risk assessment to address the additional risk of introducing and spreading CSFV due to the reintroduction of wild boar. In this paper, we present the part of the risk assessment that deals with the spread of CSFV between the hypothetical wild-boar population and the domestic population. Furthermore, the economic impact is assessed taking the perspective of the Danish national budget and the Danish pig industry. We used InterSpreadPlus to model the differential classical swine fever (CSF) risk due to wild boar. Nine scenarios were run to elucidate the effect of: (a) presence of wild boar (yes/no), (b) locations for the index case (domestic pig herd/wild-boar group), (c) type of control strategy for wild boar (hunting/vaccination) and (d) presence of free-range domestic pigs. The presence of free-range wild boar was simulated in two large forests using data from wildlife studies and Danish habitat data. For each scenario, we estimated (1) the control costs borne by the veterinary authorities, (2) the control-related costs to farmers and (3) the loss of exports associated with an epidemic. Our simulations predict that CSFV will be transmitted from the domestic pig population to wild boar if the infected domestic pig herd is located close to an area with wild boar (<5 km). If an outbreak begins in the wild-boar population, the epidemic will last longer and will occasionally lead to several epidemics because of periodic transfer of virus from groups of infected wild boar to domestic pig herds. The size and duration of the epidemic will be reduced if there are no free-range domestic pig herds in the area with CSF-infected wild boar. The economic calculations showed that the total national costs for Denmark (i.e. the direct costs to the national budget and the costs to the pig industry) related to an outbreak of CSF in Denmark will be highly driven by the reactions of the export markets and in particular of the non-EU markets. Unfortunately, there is a substantial amount of uncertainty surrounding this issue. If hunting is used as a control measure, the average expenses related to a CSF outbreak will be 40% higher if wild boar are present compared with not present. However, a vaccination strategy for wild boar will double the total costs compared with a hunting strategy.

Antidepressant use in Denmark, as in many developed countries, has substantially increased during recent years, coinciding with a decreasing suicide rate. In a nationwide observational cohort study with linkage of registers of all prescribed antidepressants and recorded suicides in Denmark from 1995 to 2000, we investigated the relation between continued treatment with antidepressants and suicide in a population of all patients discharged from hospital psychiatry with a diagnosis of depressive disorder. Patients discharged from hospital psychiatry with a diagnosis of depressive disorder had a highly increased rate of suicide. Those who continued treatment with antidepressants had a decreased rate of suicide compared with those who purchased antidepressants once (rate ratio: 0.31, 95% confidence interval: 0.26-0.36). Further, the rate of suicide decreased consistently with the number of prescriptions. On individualized data from a cohort of patients with a known history of depressive disorder, continued antidepressant treatment was associated with reduced risk of suicide.

Recent studies have suggested that stress in a pregnant mother may affect the future health of the unborn child negatively. An excellent proxy for health problems is the use of healthcare resources. Using nationwide data, we examined whether persons born to mothers who lost a close relative during pregnancy have more contacts to general practice. Population-based cohort study. Denmark. We included all children born in Denmark from 1973 to 2002 (N=2 032 528). Exposure of prenatal stress was defined as maternal bereavement by the death of a close relative during the antenatal period. The outcome of interest was contact with general practice between 2003 and 2009 when the participants were between 1 and 35 years of age. Poisson regression was used to assess the association between exposure and outcome. Contacts to general practitioner. Overall, persons exposed to prenatal stress had 2% more GP contacts than those not exposed, primarily due to increased utilisation of healthcare services during late adolescence and early adulthood. The exposed persons born to mothers who had lost a spouse had a higher risk (relative risk (RR) 1.12, 95% CI 1.10 to 1.14) and so did those born to mothers who had lost a close relative due to unexpected death (RR 1.06, 95% CI 1.05 to 1.06). Exposed persons had more contacts to general practice in daytime and more psychometric tests, talk therapies and C reactive protein tests than unexposed persons. Prenatal stress following maternal bereavement was associated with a slightly increased utilisation of primary healthcare, mainly due to increased healthcare needs related to mental health and infections. Understanding how stress during pregnancy influences the future health of the child is an important aspect of prenatal care. Published by the BMJ Publishing Group Limited.

To examine and compare the prevalence of coronary artery calcification (CAC) and the frequency of cardiac events in a background population and a cohort of patients with non-specific chest pain (NSCP) who present to an emergency or cardiology department and are discharged without an obvious reason for their symptom. A double-blinded, prospective, observational cohort study that measures both CT-determined CAC scores and cardiac events after 1 year of follow-up. Emergency and cardiology departments in the Region of Southern Denmark. In total, 229 patients with NSCP were compared with 722 patients from a background comparator population. Prevalence of CAC and incidence of unstable angina (UAP), acute myocardial infarction (MI), ventricular tachycardia (VT), coronary revascularisation and cardiac-related mortality 1 year after index contact. There was no significant difference in the prevalence of CAC (OR 0.9 (95% CI 0.6 to 1.3), P=0.546) or the frequency of cardiac endpoints (P=0.64) between the studied groups. When compared with the background population, the OR for patients with NSCP for a CAC >100 Agatston units (AU) was 1.0 (95% CI 0.6 to 1.5), P=0.826. During 1 year of follow-up, two (0.9%) patients with NSCP underwent cardiac revascularisation, while none experienced UAP, MI, VT or death. In the background population, four (0.6%) participants experienced a clinical cardiac endpoint; two had an MI, one had VT and one had a cardiac-related death. The prevalence of CAC (CAC >0 AU) among patients with NSCP is comparable to a background population and there is a low risk of a cardiac event in the first year after discharge. A CAC study does not provide notable clinical utility for risk-stratifying patients with NSCP.

Kierkegaard, Patrick

2015-05-01

The aim of this study is to survey telemedicine services currently in operation across Denmark. The study specifically seeks to answer the following questions: What initiatives are deployed within the different regions? What are the motivations behind the projects? What technologies are being utilized? What medical disciplines are being supported using telemedicine systems? All data were surveyed from the Telemedicinsk Landkort, a newly created database designed to provide a comprehensive and systematic overview of all telemedicine technologies in Denmark. The results of this study suggest that a growing numbers of telemedicine initiatives are currently in operation across Denmark but that considerable variations exist in terms of regional efforts as the number of operational telemedicine projects varied from region to region. The results of this study provide a timely picture of the factors that are shaping the telemedicine landscape of Denmark and suggest potential strategies to help policymakers increase and improve national telemedicine deployment.

Objective We investigated the association between socioeconomic factors and the attainment of treatment goals and pharmacotherapy in patients with type 2 diabetes in Denmark. Design A cross-sectional population study. Setting The municipality of Naestved, Denmark. Subjects We studied 907 patients with type 2 diabetes identified from a random sample of 21,205 Danish citizens. Main outcome measures The proportion of patients who were not achieving goals for diabetes care based on their HbA1c, LDL-cholesterol, blood pressure, and lifestyle, and the proportion of patients who were treated with antihypertensive and cholesterol- and glucose-lowering medication. Methods We investigated the association of the socioeconomic factors such as age, gender, education, occupation, income, and civil status and attainment of treatment goals and pharmacotherapy in logistic regression analyses. We investigated effect modification of cardiovascular disease and kidney disease. Results Middle age (40–65 years), low education level (i.e. basic schooling), and low household income (i.e. less than 21,400 € per year) were associated with nonattainment of goals for diabetes care. The association of socioeconomic factors with attainment of individual treatment goals varied. Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure. Socioeconomic factors were not associated with treatment goals for hyperglycemia. Socioeconomic factors were inconsistently associated with pharmacotherapy. There was no difference in contacts to general practitioners according to SES. Conclusions In a country with free access to health care, the socioeconomic factors such as middle age, low education, and low income were associated with nonattainment of goals for diabetes care. Key points Middle age, low education, and low income were associated with nonattainment of goals for diabetes care, especially for lifestyle goals. Patients with low socioeconomic status were more often obese, physically inactive, smoking, and had elevated blood pressure. Association of socioeconomic factors with pharmacotherapy was inconsistent. PMID:28277046

Previous caesarean delivery and intended mode of delivery after caesarean are well-known individual risk factors for uterine rupture. We examined if different national rates of uterine rupture are associated with differences in national rates of previous caesarean delivery and intended mode of delivery after a previous caesarean delivery. This study is an ecological study based on data from a retrospective cohort in the Nordic countries. Data on uterine rupture were collected prospectively in each country as part of the Nordic obstetric surveillance study and included 91% of all Nordic deliveries. Information on the comparison population was retrieved from the national medical birth registers. Incidence rate ratios by previous caesarean delivery and intended mode of delivery after caesarean were modelled using Poisson regression. The incidence of uterine rupture was 7.8/10 000 in Finland and 4.6/10 000 in Denmark. Rates of caesarean (21.3%) and previous caesarean deliveries (11.5%) were highest in Denmark, while the rate of intended vaginal delivery after caesarean was highest in Finland (72%). National rates of uterine rupture were not associated with the population rates of previous caesarean but increased by 35% per 1% increase in the population rate of intended vaginal delivery and in the subpopulation of women with previous caesarean delivery by 4% per 1% increase in the rate of intended vaginal delivery. National rates of uterine rupture were not associated with national rates of previous caesarean, but increased with rates of intended vaginal delivery after caesarean. © 2017 John Wiley & Sons Ltd.

The study includes 330 MG patients aged 18 to 65 years old identified from hospital diagnoses and dispensed prescriptions, and twenty references from the Danish population matching each MG patient on age, gender, and profession. Main outcome measures are labour market participation (yes/no) and long-term sick leave ≥9 weeks (yes/no) with follow-up at 1- and 2 years after the time of MG diagnosis or match. Based on complete person-level information on all public transfer payments in Denmark, persons having no labour market participation are defined as individuals receiving social benefits for severely reduced workability, flexijob, and disability pension. MG is consistently associated with higher odds of having no labour market participation and long-term sick leave compared with the general Danish population (no labour market participation & ≥9 weeks sick leave at 2-year follow-up, adjusted OR (95% CI): 5.76 (4.13 to 8.04) & 8.60 (6.60 to 11.23)). Among MG patients, females and patients treated with both acetylcholinesterase inhibitors and immunosuppression have higher odds of lost labour market participation and long-term sick leave. This study suggests that MG patients have almost 6 times higher odds of no labour market participation and almost 9 times higher odds of long-term sick leave 2 years after diagnosis compared with the general Danish population. In particular female MG patients and patients treated with both acetylcholinesterase and immunosuppression have high odds of a negative labour market outcome. Future research should focus on predictors in workplace and labour market policy of labour market participation among MG patients.

Treatment results for neuroblastoma in Denmark have been poorer than in other Nordic countries, so we investigated whether a change in incidence, stage distribution and survival had occurred between 1981 and 2000. Clinical data were retrieved from the medical charts of 160 children <15 years of age with extra-cranial neuroblastoma (n=139) or ganglioneuroblastoma (n=21) diagnosed in Denmark between 1981 and 2000. The minimal follow-up time was 52 months. Statistical analyses were performed in STATA. The incidence was 8.55 per million children below 15 years of age (world standard 9.6) and 42.6 per million children below 12 months of age, and it has remained unchanged since 1970. The median age at diagnosis was 27 months. In all, 32% of the children were aged below 12 months at diagnosis, 53% had metastatic disease and in 12% the diagnosis was made incidentally. Prognostic factors such as age, stage and site of primary tumour were the same as in other studies and did not change. During the study period, the mortality rate decreased steadily, and the 5-year survival rate increased from 38% in 1981–1985 to 59% in 1996–2000, corresponding to the level found in other Western countries. Increased survival was also seen in children with metastatic disease. Participation in international studies, better supportive care and possibly postoperative autologous stem cell transplantation may have contributed to the increased survival. PMID:19223904

Sickness absence is of considerable concern in both Norway and Denmark. Labour Force Surveys indicate that absence in Norway is about twice that in Denmark and twice that of the mean reported by the Organisation for Economic Co-operation and Development. This study compares absence patterns according to age, percentage of employment, and occupation between municipal employees in the health and care sectors in two municipalities in Norway and Denmark. Data recorded in the personnel registers of the municipalities of Kristiansand, Norway and Aarhus, Denmark were extracted for the years 2004 and 2008, revealing 3498 and 7751 employee-years, respectively. We calculated absence rates together with number of sick leave episodes, and their association with the above-mentioned covariates. Gender-specific comparative descriptive statistics and negative binomial regression analysis were performed. The sickness absence rate in women was 11.3% in Norway (95% confidence interval [CI] 11.2-11.4) and 7.0% in Denmark (95% CI 7.0-7.1) whereas mean number of sick leave episodes among women was 2.4 in Denmark, compared to 2.3 in Norway (p = 0.02). Young employees in Denmark had more sick leave episodes than in Norway. Proportion of absentees was higher in Denmark compared to Norway (p < 0.0001). The finding of that more employees in Denmark have more frequent, but shorter sick leave episodes compared to Norway, for whatever reasons, may indicate that more frequent sick leaves episodes prevent higher sick leaves rates.

Objective To compare socioeconomic, sociodemographic, and living area differences in children's use of GP services in five Nordic countries from the 1980s to the 1990s and to analyse trends during the period. Design Cross sectional population surveys using random samples comprising 3000 children aged 2–17 years were conducted in 1984 and 1996 in five Nordic countries. Time trends in use of GP services were studied in each country by age, sex, parents' highest level of education, and living area. Setting Five Nordic countries, Denmark, Finland, Iceland, Norway, and Sweden in 1984 and 1996. Participants A total sample of 15 000 children aged 2–17 years. Altogether 3000 children were selected at random from the national population registers of the national bureaus of statistics in each country. Main outcome Health services utilisation on the basis of responses to a questionnaire item asking whether the parents had consulted a GP with regard to their children's health during the previous three months. Main results The prevalence of children's utilisation of GP services varied from 14% in 1984 in Sweden to 28% in 1996 in Iceland. A clear time trend towards increasing utilisation of GP services (p<0.05) was found in all countries except in Denmark. Odds ratios for time trends (1984 = 1.00) varied from 1.22 (1.02 to 1.46) in Sweden to 1.92 (1.62 to 2.30) in Norway. After adjusting for independent variables, a statistically borderline significant declining utilisation trend (OR = 0.85 (0.70 to 1.03)) was found for Denmark. Conclusion Children's use of GP services has increased significantly in four of the five Nordic countries. PMID:16415268

The annual prevalence of antiepileptic drug (AED) prescribing reported in the literature differs considerably among European countries due to use of different type of data sources, time periods, population distribution, and methodologic differences. This study aimed to measure prevalence of AED prescribing across seven European routine health care databases in Spain, Denmark, The Netherlands, the United Kingdom, and Germany using a standardized methodology and to investigate sources of variation. Analyses on the annual prevalence of AEDs were stratified by sex, age, and AED. Overall prevalences were standardized to the European 2008 reference population. Prevalence of any AED varied from 88 per 10,000 persons (The Netherlands) to 144 per 10,000 in Spain and Denmark in 2001. In all databases, prevalence increased linearly: from 6% in Denmark to 15% in Spain each year since 2001. This increase could be attributed entirely to an increase in "new," recently marketed AEDs while prevalence of AEDs that have been available since the mid-1990s, hardly changed. AED use increased with age for both female and male patients up to the ages of 80 to 89 years old and tended to be somewhat higher in female than in male patients between the ages of 40 and 70. No differences between databases in the number of AEDs used simultaneously by a patient were found. We showed that during the study period of 2001-2009, AED prescribing increased in five European Union (EU) countries and that this increase was due entirely to the newer AEDs marketed since the 1990s. Using a standardized methodology, we showed consistent trends across databases and countries over time. Differences in age and sex distribution explained only part of the variation between countries. Therefore, remaining variation in AED use must originate from other differences in national health care systems. Wiley Periodicals, Inc. © 2014 International League Against Epilepsy.

Asylum-seeking children constitute a vulnerable group with high prevalence and risk for mental health problems. The aim of this study was to compare policies of access to healthcare services, including physical examination and screening for mental health problems on arrival, for accompanied asylum-seeking children in the Nordic countries. This study was based on the national reports "Reception of refugee children in the Nordic countries" written by independent national experts for the Nordic Network for Research on Refugee Children, supplemented by information from relevant authorities. In Sweden, Norway and Iceland, asylum-seeking children had access to healthcare services equal to children in the general population. On a policy level, Denmark imposed restrictions on non-acute hospitalisations and prolonged specialist treatments. Regarding health examinations, Sweden deviated from the Nordic pattern by not performing these systematically. In Denmark, Iceland, and some counties in Sweden, but not in Norway, screening for mental health problems was offered to asylum-seeking children. Access to healthcare services for asylum-seeking children differs in the Nordic countries; the consequences of these systematic differences for the individual asylum-seeking child are unknown. For asylum-seeking children, access to healthcare has to be considered in a wider context that includes the core conditions of being an asylum-seeker. A comparative study at policy level needs to be supplemented with empirical follow-up studies of the well-being of the study population to document potential consequences of policies in practice.

Explaining the increase in the prevalence of autism spectrum disorders: the proportion attributable to changes in reporting practices.

Hansen, Stefan N; Schendel, Diana E; Parner, Erik T

2015-01-01

The prevalence of autism spectrum disorders (ASDs) has increased markedly in recent decades, which researchers have suggested could be caused in part by nonetiologic factors such as changes in diagnosis reporting practices. To our knowledge, no study has quantified the degree to which changes in reporting practices might explain this increase. Danish national health registries have undergone a change in diagnostic criteria in 1994 and the inclusion of outpatient contacts to health registries in 1995. To quantify the effect of changes in reporting practices in Denmark on reported ASD prevalence. We used a population-based birth cohort approach that includes information on all individuals with permanent residence in Denmark. We assessed all children born alive from January 1, 1980, through December 31, 1991, in Denmark (n=677915). The children were followed up from birth until ASD diagnosis, death, emigration, or the end of follow-up on December 31, 2011, whichever occurred first. The analysis uses a stratified Cox proportional hazards regression model with the changes in reporting practices modeled as time-dependent covariates. The change in diagnostic criteria in 1994 and the inclusion of outpatient diagnoses in 1995. Autism spectrum disorders. For Danish children born during the study period, 33% (95% CI, 0%-70%) of the increase in reported ASD prevalence could be explained by the change in diagnostic criteria alone; 42% (95% CI, 14%-69%), by the inclusion of outpatient contacts alone; and 60% (95% CI, 33%-87%), by the change in diagnostic criteria and the inclusion of outpatient contacts. Changes in reporting practices can account for most (60%) of the increase in the observed prevalence of ASDs in children born from 1980 through 1991 in Denmark. Hence, the study supports the argument that the apparent increase in ASDs in recent years is in large part attributable to changes in reporting practices.

To compare the epidemiology of tuberculosis (TB) in Denmark, Sweden and Finland, by focusing on the native population in order to identify epidemiologic differences and thus indirectly possible differences in TB control. TB incidence trends from 1990 through 2015 were compared among the countries. In addition, for the periods 2012-2013 and 2014-2015, genotyping data were compared. Genotyping was performed using the 24-locus mycobacterial interspersed repetitive unit-variable number of tandem repeat (MIRU-VNTR) method in Denmark and Sweden. For Finland, spoligotyping in conjunction with the 15-locus MIRU-VNTR method was used for 2012-2013 and translated into the 24-locus MIRU-VNTR when feasible, and for 2014-2015 only MIRU-VNTR was used. Both incidence trends and molecular epidemiology were assessed for native cases. The average annual rate of change in TB incidence for native Danes was -2.4% vs. -6.1% and -6.9% for native Swedes and Finns respectively. In 2012-2013 Denmark had 52 native cases in the largest transmission chain vs. three cases in Sweden and ten in Finland, and during the same period the clustering rate for native Danes was 48.8% vs. 6.5% and 18.2% for native Swedes and Finns respectively. For 2014-2015, a similar pattern was seen. The decline of TB among natives in Denmark is slower than for Sweden and Finland, and it seems Denmark has more active transmission among natives. The focused assessment on basic native TB epidemiology reveals striking differences in TB transmission among otherwise similar low-TB-incidence countries.

The Odense University Pharmacoepidemiological Database (OPED) is a prescription database established in 1990 by the University of Southern Denmark, covering reimbursed prescriptions from the county of Funen in Denmark and the region of Southern Denmark (1.2 million inhabitants). It is still active and thereby has more than 25 years of continuous coverage. In this MiniReview, we review its history, content, quality, coverage, governance and some of its uses. OPED's data include the Danish Civil Registration Number (CPR), which enables unambiguous linkage with virtually all other health-related registers in Denmark. Among its research uses, we review record linkage studies of drug effects, advanced drug utilization studies, some examples of method development and use of OPED as sampling frame to recruit patients for field studies or clinical trials. With the advent of other, more comprehensive sources of prescription data in Denmark, OPED may still play a role as in certain data-intensive regional studies. © 2017 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

To provide comprehensive real-world evidence on societal diabetes-attributable costs in Denmark. National register data are linked on an individual level through unique central personal registration numbers in Denmark. All patients in the Danish National Diabetes Register in 2011 (N = 318 729) were included in this study. Complication status was defined according to data from the Danish National Hospital Register. Diabetes-attributable costs were calculated as the difference between costs of patients with diabetes and the expected costs given the annual resource consumption of the diabetes-free population. Societal costs attributable to diabetes were estimated to be at least 4.27 billion EUR in 2011, corresponding to 14,349 EUR per patient-year. A twofold higher healthcare resource usage was found for patients with diabetes as compared with the diabetes-free population. Attributable costs, grouped according to different components, were 732 million EUR for primary and secondary care services, 153 million EUR for pharmaceutical drugs, 851 million EUR for nursing services, 1.77 billion EUR in lost productivity and 761 million EUR for additional costs. A steep increase in diabetes-attributable costs was found for patients with major complications compared with patients without complications across all cost components. For attributable healthcare costs this increase was estimated to be 6,992 EUR per person-year after controlling for potential confounders. Nearly half of the total costs of patients with diabetes can be attributed directly to their diabetes. The majority of costs are incurred among patients with major complications pointing to the importance of secondary preventive efforts among patients with diabetes. © 2015 The Authors.

Denmark has a high incidence of invasive listeriosis (0.9 cases/100,000 population in 2012). We analyzed patient data, clinical outcome, and trends in pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) of Listeria monocytogenes strains isolated in Denmark during 2002-2012. We performed 2-enzyme PFGE and serotyping on 559 isolates and MLST on 92 isolates and identified some correlation between molecular type and clinical outcome and patient characteristics. We found 178 different PFGE types, but isolates from 122 cases belonged to just 2 closely related PFGE types, clonal complex 8 and sequence type 8. These 2 types were the main cause of a peak in incidence of invasive listeriosis during 2005-2009, possibly representing an outbreak or the presence of a highly prevalent clone. However, current typing methods could not fully confirm these possibilities, highlighting the need for more refined discriminatory typing methods to identify outbreaks within frequently occurring L. monocytogenes PFGE types.

Skriver, Mette Vinther; Væth, Michael; Støvring, Henrik

2018-01-01

The standardized mortality ratio (SMR) is a widely used measure. A recent methodological study provided an accurate approximate relationship between an SMR and difference in lifetime expectancies. This study examines the usefulness of the theoretical relationship, when comparing historic mortality data in four Scandinavian populations. For Denmark, Finland, Norway and Sweden, data on mortality every fifth year in the period 1950 to 2010 were obtained. Using 1980 as the reference year, SMRs and difference in life expectancy were calculated. The assumptions behind the theoretical relationship were examined graphically. The theoretical relationship predicts a linear association with a slope, [Formula: see text], between log(SMR) and difference in life expectancies, and the theoretical prediction and calculated differences in lifetime expectancies were compared. We examined the linear association both for life expectancy at birth and at age 30. All analyses were done for females, males and the total population. The approximate relationship provided accurate predictions of actual differences in lifetime expectancies. The accuracy of the predictions was better when age was restricted to above 30, and improved if the changes in mortality rate were close to a proportional change. Slopes of the linear relationship were generally around 9 for females and 10 for males. The theoretically derived relationship between SMR and difference in life expectancies provides an accurate prediction for comparing populations with approximately proportional differences in mortality, and was relatively robust. The relationship may provide a useful prediction of differences in lifetime expectancies, which can be more readily communicated and understood.

During cancer treatment children have reduced contact with their social network of friends, and have limited participation in education, sports, and leisure activities. During and following cancer treatment, children describe school related problems, reduced physical fitness, and problems related to interaction with peers. The RESPECT study is a nationwide population-based prospective, controlled, mixed-methods intervention study looking at children aged 6-18 years newly diagnosed with cancer in eastern Denmark (n=120) and a matched control group in western Denmark (n=120). RESPECT includes Danish-speaking children diagnosed with cancer and treated at pediatric oncology units in Denmark. Primary endpoints are the level of educational achievement one year after the cessation of first-line cancer therapy, and the value of VO2max one year after the cessation of first-line cancer therapy. Secondary endpoints are quality of life measured by validated questionnaires and interviews, and physical performance. RESPECT includes a multimodal intervention program, including ambassador-facilitated educational, physical, and social interventions. The educational intervention includes an educational program aimed at the child with cancer, the child's schoolteachers and classmates, and the child's parents. Children with cancer will each have two ambassadors assigned from their class. The ambassadors visit the child with cancer at the hospital at alternating 2-week intervals and participate in the intervention program. The physical and social intervention examines the effect of early, structured, individualized, and continuous physical activity from diagnosis throughout the treatment period. The patients are tested at diagnosis, at 3 and 6 months after diagnosis, and one year after the cessation of treatment. The study is powered to quantify the impact of the combined educational, physical, and social intervention programs. RESPECT is the first population-based study to examine the effect of early rehabilitation for children with cancer, and to use healthy classmates as ambassadors to facilitate the normalization of social life in the hospital. For children with cancer, RESPECT contributes to expanding knowledge on rehabilitation that can also facilitate rehabilitation of other children undergoing hospitalization for long-term illness.

Iodine fortification (IF) may contribute to changes in costs of thyroid disease treatment through changes in disease patterns. From a health economic perspective, assessment of the development in costs of thyroid disease treatment in the population is pertinent. To assess the trends in annual medicine and hospital costs of thyroid disease treatment during 1995-2015 in Denmark, i.e., before and after the introduction of mandatory IF in 2000. Information on treatments for thyroid disease (antithyroid medication, thyroid hormone therapy, thyroid surgery, and radioiodine treatment) was obtained from nationwide registers. Costs were valued at 2015 prices using sales prices for medicines and the Danish Diagnosis-Related Group (DRG) and Danish Ambulatory Grouping System (DAGS) tariffs of surgeries/radioiodine treatments. Results were adjusted for changes in population size and age and sex distribution. The total direct medicine and hospital costs of thyroid disease treatment increased from EUR ∼190,000 per 100,000 persons in 1995 to EUR ∼270,000 per 100,000 persons in 2015. This was mainly due to linearly increased costs of thyroid hormone therapy and increased costs of thyroid surgery since 2008. Costs of antithyroid medication increased slightly and transiently after IF, while costs of radioiodine treatment remained constant. Costs of thyroid hormone therapy and thyroid surgery did not follow the development in the prevalence of hypothyroidism and structural thyroid diseases observed in concurrent studies. The costs of total direct medicine and hospital costs for thyroid disease treatment in Denmark increased from 1995 to 2015. This is possibly due to several factors, e.g., changes in treatment practices, and the direct effect of IF alone remains to be estimated.

Recently, significant contributions to the study of endocrinology and metabolism have been made. The national contribution, however, has not been reported. The aim of this study was to assess national efforts in the field of endocrinology and metabolism. A Web of Science search was performed using subject categories "endocrinology & metabolism" to identify articles published from 2010 to 2014. The total and per capita numbers of articles and citations were analysed for different countries. A total of 79,394 articles were published on endocrinology and metabolism from 2010 to 2014. Most were published in North America, East Asia, and Europe. The majority (82.28%) were reported by authors in high-income countries, 17.64% were published in middle-income countries, and only 0.08% were published in low-income countries. Authors in the United States published the most articles (27.38%), followed by China (7.22%), Italy (5.70%), the United Kingdom (5.6%), and Japan (5.54%). Articles published by authors in the United States had the most citations (260,934). A positive correlation was found between the number of publications and population/gross domestic product (GDP; p < 0.01). When normalised to population size, the ranking for the most publications was Denmark, Sweden, and the Netherlands; when normalised to GDP, the ranking was Denmark, Greece, and the Netherlands. The majority of endocrinology and metabolism articles were published by authors from high-income countries with few from low-income countries. The United States was the most productive country. However, when population size and GDP were considered, some European countries were ranked higher.

Working Time Arrangements as Potential Risk Factors for Ischemic Heart Disease Among Workers in Denmark: A Study Protocol

PubMed Central

2016-01-01

Background It has long been suspected that a worker’s risk of developing an ischemic heart disease (IHD) may be influenced by his or her working time arrangements. A multitude of studies have been performed, and special attention has been given to long working hours and nighttime work. The statistical powers of the individual studies have, however, generally been too low to either dismiss or confirm an actual relationship, and meta-analyses of underpowered studies are generally associated with publication bias. Hence, uncertainty remains and whether these factors indeed are related to IHD has yet to be settled. Objective This project will test whether the incidences of IHD and usage of antihypertensive drugs among employees in Denmark are independent of weekly working hours and nighttime work. The objective of this paper is to present the intended analyses. Methods We will link individual participant data from the Danish labor force survey, 1999–2013, to data on socioeconomic status, industry, emigrations, redeemed prescriptions, hospitalizations, and deaths from registers covering the entire population of Denmark. The study will include approximately 160,000 participants, who will be followed through the registers, from the time of the interview until the end of 2014, for first occurrence of IHD and for antihypertensive drug treatment. We will use Poisson regression to analyze incidence rates as a function of nighttime work and of weekly working hours. Results We expect results to be ready in mid-2017. Conclusions To our knowledge, this will be the largest study ever of its kind. It will, moreover, be free from hindsight bias, since the hypotheses, inclusion criteria, significance levels, and statistical models will be completely defined and published before we are allowed to link the exposure data to the outcome data.

Objectives Prior work has examined the shape of the income–mortality association, but work has not compared gradients between countries. In this study, we focus on changes over time in the shape of income–mortality gradients for 4 Nordic countries during a period of rising income inequality. Context and time differentials in shape imply that the relationship between income and mortality is not fixed. Setting Population-based cohort study of Denmark, Finland, Norway and Sweden. Participants We collected data on individuals aged 25 or more in 1995 (n=12.98 million individuals, 0.84 million deaths) and 2003 (n=13.08 million individuals, 0.90 million deaths). We then examined the household size equivalised disposable income at the baseline year in relation to the rate of mortality in the following 5 years. Results A steep income gradient in mortality in men and women across all age groups except the oldest old in Denmark, Finland, Norway and Sweden. From the 1990s to 2000s mortality dropped, but generally more so in the upper part of the income distribution than in the lower part. As a consequence, the shape of the income gradient in mortality changed. The shift in the shape of the association was similar in all 4 countries. Conclusions A non-linear gradient exists between income and mortality in most cases and because of a more rapid mortality decline among those with high income the income gradient has become steeper over time.

In some insect species, females may base their choice for a suitable mate on male odor. In the red mason bee, Osmia bicornis, female choice is based on a male's odor bouquet as well as its thorax vibrations, and its relatedness to the female, a putative form of optimal outbreeding. Interestingly, O. bicornis can be found as two distinct color morphs in Europe, which are thought to represent subspecies and between which we hypothesize that female discrimination may be particularly marked. Here we investigated (i) if these two colors morphs do indeed represent distinct, reproductively differentiated populations, (ii) how odor bouquets of male O. bicornis vary within and between populations, and (iii) whether variation in male odor correlates with genetic distance, which might represent a cue by which females could optimally outbreed. Using GC and GC-MS analysis of male odors and microsatellite analysis of males and females from 9 populations, we show that, in Denmark, an area of subspecies sympatry, the two color morphs at any one site do not differ, either in odor bouquet or in population genetic differentiation. Yet populations across Europe are distinct in their odor profile as well as being genetically differentiated. Odor differences do not, however, mirror genetic differentiation between populations. We hypothesize that populations from Germany, England and Denmark may be under sexual selection through female choice for local odor profiles, which are not related to color morph though which could ultimately lead to population divergence and speciation.

Previous studies have shown systematic differences between the Nordic Countries in population-based relative survival following a kidney or urinary bladder cancer diagnosis. Comparison of bladder cancer over time and between Nordic registries is complicated by variable coding practices with respect to the inclusion of in situ cases with invasive tumours. Five-year relative survival of patients with urinary cancer diagnosed in the Nordic countries 1964-2003 and followed up for death through 2006 was studied and contrasted with developments in incidence and mortality. The survival following bladder cancer was higher than for kidney cancer and highest for men. Survival increased over the years in all countries, more for kidney cancer than bladder cancer. For Danish kidney cancer patients, the rate of increase over all the years has been lower than in the other countries, especially among women, resulting in a survival in Denmark some 10-20% points lower than elsewhere in 1999-2003. Danish bladder cancer patient survival was in the last period 4% points lower among men and 10% points lower among women than in the other Nordic countries. The differences were mainly found in the first year following diagnosis, where a higher excess mortality in Denmark was observed. Survival decreased with higher age at diagnosis. The increasing 5-year relative survival in all the Nordic countries for both kidney and bladder cancer are promising, but for kidney cancer a higher percentage detected coincidentally during an imaging investigation for other diseases could play a role. Denmark had the lowest survival, despite their known practice of including benign conditions with invasive bladder cancers. The lower Danish survival after kidney and bladder cancer in the first year after diagnosis could be due to later diagnosis on average, a higher co-morbidity from smoking-related diseases, and perhaps, less adequate cancer treatment and management in Denmark.

To investigate the effectiveness of systematic screening for multifaceted cardiovascular disease (CVD) in postmenopausal women on all cause mortality and, secondarily, on CVD morbidity. Effectiveness was also evaluated across age strata. This was a population based, prospective, parallel cohort study. In total, 107,491 women born in 1936-1951 living in the Central Denmark region were identified in the Danish Civil Registration System. From this population, all women born in 1936, 1941, 1946, and 1951 (n = 1984) living in the Viborg municipality were invited to attend screening. Of those invited to the screening, 1474 (74.3%) attended. The control group included all women from the general population born in 1936-1951 and living in the Central Denmark Region, excluding those invited for the screening. Information on medication and comorbidities prior to inclusion and study outcomes were retrieved from national registries for both groups. The screening included examination for abdominal aortic aneurysm (AAA), peripheral arterial disease (PAD), carotid plaque (CP), potential hypertension (HT), atrial fibrillation (AF), diabetes mellitus (DM), and dyslipidaemia. The adjusted Cox proportional hazards model with the intention to screen principle was used to assess effectiveness for the total population and across age groups. During follow up (median 3.3 years, IQR 2.9-3.9), the adjusted hazard ratios (HRs) for invited versus controls were the following: all cause mortality, 0.89 (95% CI 0.71-1.12); myocardial infarction (MI), 1.26 (95% CI 0.52-3.07); ischaemic heart disease (IHD), 0.72 (95% CI 0.49-1.05); PAD, 1.07 (95% CI 0.49-2.31); and ischaemic stroke, 1.20 (95% CI 0.78-1.85). A substantial number of women with AAA, PAD, and/or CP declined prophylactic therapy: 45% for antiplatelet and 35% for cholesterol lowering agents. This multifaceted screening offer to a general population sample of postmenopausal women had no effects on all cause mortality or hospital admission for MI, IHD, PAD, and stroke within a short-term follow up period.

We examined the prevalence of underweight and obesity in children with congenital heart disease (CHD) compared with the general population. Using the Danish National Patient Registry, we identified individuals born and diagnosed with CHD in Denmark during 1996-2012 who were alive at 1 year of age. A unique personal identifier enabled identification of CHD subjects, as well as birth year and sex-matched (1:10) general population controls. The Children's Database has recorded height and weight measured by clinical providers at preventive health checks offered to all children in Denmark. Data recording were made mandatory in 2011. Obesity was defined as body mass index (BMI) above the 95thpercentile and underweight as BMI below the fifth percentile for age and sex. We determined the prevalence of underweight and obesity at study subjects' first height and weight recording. For those underweight at age 1 year, prevalence of underweight and obesity at later recordings was assessed. We identified 9194 children with CHD of which 2679 (29%) had at least one recording of height and weight. The control cohort demonstrated a similar portion of anthropometric data: 30 047 (31%) of 96 585 controls. The prevalence of underweight and obesity at CHD study subjects' first height and weight recording was 9.7% (95% CI 8.7 to 11) and 4.1% (95% CI 3.4 to 4.9), respectively. Among individuals with CHD who were underweight at age 1 year (n=78), 51 (65%) had additional BMI recordings between ages 2 and 5 years with a subsequently diminished prevalence of underweight of 27% (95% CI 20 to 35) and none were obese. The CHD population had an increased prevalence of underweight compared with the general population. Data indicated potential for BMI normalisation among those initially underweight at age 1 year. The prevalence of obesity in children with CHD was comparable with that of the general population.

It has been hypothesised that return to work rates among sick-listed workers increases with enterprise size. The aim of the present study was to estimate the effect of enterprise size on the odds of returning to work among previously employed stroke patients in Denmark, 2000-2006. We used a prospective design with a 2 year follow-up period. The study population consisted of 13,178 stroke patients divided into four enterprise sizes categories, according to the place of their employment prior to the stroke: micro (1-9 employees), small (10-49 employees), medium (50-249 employees) and large (>250 employees). The analysis was based on nationwide data on enterprise size from Statistics Denmark merged with data from the Danish occupational hospitalisation register. We found a statistically significant association (p = 0.034); each increase in enterprise size category was followed by an increase in the estimated odds of returning to work. The chances of returning to work after stroke increases as the size of enterprise increases. Preventive efforts and research aimed at finding ways of mitigating the effect are warranted.

Taxation and life expectancy in Western Europe.

PubMed

Bagger, P J

2004-06-01

With the exception of Denmark, life expectancy in Western Europe has shown a significant increase over the last decades. During that period of time overall taxation has increased in most of the countries, especially in Denmark. We, therefore, examined whether taxation could influence life expectancy in Western Europe. We used information on the sum of income tax and employees' social contribution in percentage of gross wage earnings from the OECD database and data on disability adjusted life expectancy at birth from the World Health Organization database. We arbitrarily only included countries with populations in excess of 4 millions and thereby excluded smaller countries where tax exemption is part of the national monetary policy. We found that disability adjusted life expectancy at birth was inversely correlated to the total tax burden in Western Europe. We speculate whether a threshold exists where high taxes exert a negative influence on life expectancy despite increased welfare spending. The study suggests that tax burden should be considered among the multiple factors influencing life expectancy.

[Tuberculosis among immigrants in Scandinavian medical journals].

Steen, M

2001-06-30

The decline in incidence of tuberculosis in Scandinavia has stagnated in the last decades because of a growing number of immigrants from high incidence countries. The aim of this study was to find out what has been published on tuberculosis among immigrants in Denmark, Norway and Sweden in the main medical journals in these countries from 1995 to 2000. 23 papers on the topic were identified through PubMed searches. Eight papers were selected for a more detailed description of their content. The main medical journals in Denmark, Norway and Sweden have published papers on epidemiological aspects and clinical traits as well as the challenge for the health services of controlling tuberculosis in immigrants. The majority of patients are under the age of 40 and of African origin. They seldom infect the population of the host country. Extrapulmonary tuberculosis is relatively common. Control on arrival could be improved in all three countries. Considerable doctor's and patient's delay is not uncommon. Medical journals are an important source for knowledge on tuberculosis among immigrants from high incidence countries.

In pelagic species inhabiting large oceans, genetic differentiation tends to be mild and populations devoid of structure. However, large cetaceans have provided many examples of structuring. Here we investigate whether the sperm whale, a pelagic species with large population sizes and reputedly highly mobile, shows indication of structuring in the eastern North Atlantic, an ocean basin in which a single population is believed to occur. To do so, we examined stable isotope values in sequential growth layer groups of teeth from individuals sampled in Denmark and NW Spain. In each layer we measured oxygen- isotope ratios (δ18O) in the inorganic component (hydroxyapatite), and nitrogen and carbon isotope ratios (δ15N: δ13C) in the organic component (primarily collagenous). We found significant differences between Denmark and NW Spain in δ15N and δ18O values in the layer deposited at age 3, considered to be the one best representing the baseline of the breeding ground, in δ15N, δ13C and δ18O values in the period up to age 20, and in the ontogenetic variation of δ15N and δ18O values. These differences evidence that diet composition, use of habitat and/or migratory destinations are dissimilar between whales from the two regions and suggest that the North Atlantic population of sperm whales is more structured than traditionally accepted.

The interaction between legalization of abortion and contraception in Denmark.

PubMed

Matthiessen, P C

1979-01-01

Trends in fertility, abortion, and contraceptive practice in Denmark were analyzed, using previously compiled official statistics; the conclusion was drawn that easy access to abortion may contribute toward a decline in contraceptive practice depending on the level of contraceptive practice in the population and on the degree of confidence the population has in available contraceptive methods. In October 1973 Denmark passed a law permitting women to obtain free abortion on demand. The number of legal abortions increased from 16,500 in 1973 to 28,000 in 1975. This marked increase was not attributable to a decline in illegal abortion since that annual number had declined from 5,000 to 1,000 prior to the passage of the 1973 abortion on demand law. The increase in abortion observed from 1973-1975 was accompanied by a marked decrease in the number of oral contraceptive cycles sold. Annual sales decreased from 3.9 million cycles to 2.6 million. It was difficult to access the factors responsible for this decline. Although IUD insertions increased during this period, the increase could not adequately compensate for the reduction in oral contraceptive sales. The decline in oral contraceptive sales occurred at about the time the negative side effects associated with the pill received widespread news coverage. Some of the decline in pill usage was probably due to fear of side effects, but abortion availability also encouraged women to be more lax about taking the pill and encouraged them to rely on less effective methods of contraception. Tables provide data for Denmark in reference to: 1) number of legal abortions and the abortion rates for 1940-1977; 2) distribution of abortions by season, 1972-1977; 3) abortion rates by maternal age, 1971-1977; 4) oral contraceptive and IUD sales for 1977-1978; and 5) number of births and estimated number of abortions and conceptions, 1960-1975.

To report mortality and disability due to rheumatoid arthritis (RA) in the Nordic region (Denmark, Finland, Greenland, Iceland, Norway, and Sweden) using data from the Global Burden of Disease Study (GBD) 2015. Using the results of GBD 2015, we present rates and trends in prevalence, mortality, years of life lost, years lived with disability (YLD), and disability-adjusted life-years (DALYs) of RA in the Nordic region during 1990-2015. In 2015, the age-standardized prevalence of RA was higher in the Nordic region than the global level (0.44%, 95% uncertainty interval 0.40-0.48%, vs 0.35%, 0.32-0.38%). For women (men), DALYs increased by 2.4% (12.9%), from 29 263 (10 909) in 1990 to 29 966 (12 311) in 2015. The burden of RA as a proportion of total DALYs in women (men) increased from 0.90% (0.29%) in 1990 to 0.94% (0.36%) in 2015. Age-standardized DALY rates declined in all countries except Denmark and Greenland between 1990 and 2015. Of 315 conditions studied, RA was ranked as the 16th (37th) leading cause of YLD in women (men) in the region. Of 195 countries studied, Greenland, Finland, Denmark, Norway, Sweden, and Iceland had the 7th, 11th, 28th, 38th, 48th, and 78th highest age-standardized YLD rates for RA, respectively. The prevalence of RA in the Nordic region is higher than the global average. Current trends in population growth and ageing suggest a potential increase in RA burden in the coming decades in the region that should be considered in healthcare resources allocation.

Cerebral palsy is the most frequent motor disability in childhood, but little is known about its etiology. It has been suggested that cerebral palsy risk may be increased by prenatal thyroid hormone disturbances. The objective of this study was to investigate whether maternal thyroid disorder is associated with increased risk of cerebral palsy. A population-based cohort study using two study populations. 1) 1,270,079 children born in Denmark 1979-2007 identified in nationwide registers, and 2) 192,918 children born 1996-2009 recruited into the Danish National Birth Cohort and The Norwegian Mother and Child Cohort study, combined in the MOthers and BAbies in Norway and Denmark (MOBAND) collaboration cohort. Register-based and self-reported information on maternal thyroid disorder was studied in relation to risk of cerebral palsy and its unilateral and bilateral spastic subtypes using multiple logistic regression. Children were followed from the age of 1 year to the age of 6 years, and cerebral palsy was identified in nationwide registers with verified diagnoses. In register data, hypothyroidism was recognized in 12,929 (1.0%), hyperthyroidism in 9943 (0.8%), and unclassifiable thyroid disorder in 753 (< 0.1%) of the mothers. The odds ratio for an association between maternal thyroid disorder and bilateral spastic cerebral palsy was 1.0 (95% CI: 0.7-1.5). Maternal thyroid disorder identified during pregnancy was associated with elevated risk of unilateral spastic cerebral palsy (odds ratio 3.1 (95% CI: 1.2-8.4)). In MOBAND, 3042 (1.6%) of the mothers reported a thyroid disorder in pregnancy, which was not associated with cerebral palsy overall (odds ratio 1.2 (95% CI: 0.6-2.4)). Maternal thyroid disorder overall was not related to bilateral spastic cerebral palsy, but maternal thyroid disorder identified in pregnancy was associated with increased risk of unilateral spastic cerebral palsy. These findings should be replicated in studies making use of maternal blood samples.

To determine the mortality rate in a Danish cohort of children and adolescents diagnosed with Type 1 diabetes mellitus compared with the general population. In 1987 and 1989 we included 884 children and 1020 adolescents aged 20 years and under, corresponding to 75% of all Danish children and adolescents with Type 1 diabetes, in two nationwide studies in Denmark. Those who had participated in both investigations (n = 720) were followed until 1 January 2014, using the Danish Civil Registration System on death certificates and emigration. We derived the expected number of deaths in the cohort, using population data values from Statistics Denmark to calculate the standardized mortality ratio. Survival analysis was performed using Cox proportional hazards model. During the 24 years of follow-up, 49 (6.8%) patients died, resulting in a standardized mortality ratio of 4.8 (95% confidence interval 3.5, 6.2) compared with the age-standardized general population. A 1% increase in baseline HbA 1c (1989), available in 718 of 720 patients, was associated with all-cause mortality (hazard ratio = 1.38; 95% confidence interval 1.2, 1.6; P < 0.0001). Type 1 diabetes with multiple complications was the most common reported cause of death (36.7%). We found an increased mortality rate in this cohort of children and adolescents with Type 1 diabetes compared with the general population. The only predictor for increased risk of death up to 24 years after inclusion was the HbA 1c level in 1989. This emphasizes the importance of achieving optimal metabolic control in young people with Type 1 diabetes. © 2016 Diabetes UK.

This descriptive study sought to explore barriers faced by Deaf and hard-of-hearing (D/HH) individuals in Denmark when accessing medical and psychosocial services following large-scale disasters and individual traumatic experiences. Semi-structured interviews were conducted with nine D/HH individuals who had experienced at least one disaster or other traumatic event. Difficulties were encountered during interactions with first response and healthcare services, which centered on: (1) lack of Deaf awareness among professionals, (2) problems accessing interpreter services, (3) professionals relying on hearing relatives to disseminate information, and (4) professionals who were unwilling to adjust their speech or try different forms of communication. Barriers reported in relation to accessing psychosocial services included: (1) lack of all-Deaf or hard-of-hearing support groups, and (2) limited availability of crisis psychologists who are trained to service the needs of the hearing impaired. Suggestions for improvements to service provision were provided, including a list of practical recommendations for professionals. This study has identified significant gaps in post-disaster service provision for D/HH individuals. Results can inform policy makers and other authorities in the position to enhance existing services and/or develop new services for this vulnerable target population. Implications for Rehabilitation Being Deaf or hard-of-hearing compromises a person's ability to obtain and share vital information during times of disaster. Medical and psychosocial services are expected to play critical response roles in times of disaster, and, should be properly equipped to assist Deaf and hard-of-hearing (D/HH) individuals. In a relatively small sample, this study highlights barriers faced by D/HH individuals in Denmark when accessing first response, healthcare, and psychosocial services following large-scale disasters and individual traumatic events, all of which centered on communication problems and resulted in suboptimal care. Regarding rehabilitation after disasters, evidence-based information about how to service the heterogeneous communication needs of D/HH populations should be disseminated to professionals, and preferably incorporated into training programs.

The role of general practice in routes to diagnosis of lung cancer in Denmark: a population-based study of general practice involvement, diagnostic activity and diagnostic intervals.

Lung cancer stage at diagnosis predicts possible curative treatment. In Denmark and the UK, lung cancer patients have lower survival rates than citizens in most other European countries, which may partly be explained by a comparatively longer diagnostic interval in these two countries. In Denmark, a pathway was introduced in 2008 allowing general practitioners (GPs) to refer patients suspected of having lung cancer directly to fast-track diagnostics. However, symptom presentation of lung cancer in general practice is known to be diverse and complex, and systematic knowledge of the routes to diagnosis is needed to enable earlier lung cancer diagnosis in Denmark. This study aims to describe the routes to diagnosis, the diagnostic activity preceding diagnosis and the diagnostic intervals for lung cancer in the Danish setting. We conducted a national registry-based cohort study on 971 consecutive incident lung cancer patients in 2010 using data from national registries and GP questionnaires. GPs were involved in 68.3% of cancer patients' diagnostic pathways, and 27.4% of lung cancer patients were referred from the GP to fast-track diagnostic work-up. A minimum of one X-ray was performed in 85.6% of all cases before diagnosis. Patients referred through a fast-track route more often had diagnostic X-rays (66.0%) than patients who did not go through fast-track (49.4%). Overall, 33.6% of all patients had two or more X-rays performed during the 90 days before diagnosis. Patients whose symptoms were interpreted as non-alarm symptoms or who were not referred to fast-track were more likely to experience a long diagnostic interval than patients whose symptoms were interpreted as alarm symptoms or who were referred to fast-track. Lung cancer patients followed several diagnostic pathways. The existing fast-track pathway must be supplemented to ensure earlier detection of lung cancer. The high incidence of multiple X-rays warrants a continued effort to develop more accurate lung cancer tests for use in primary care.

The aim of the study is to compare differences in cancer stage at diagnosis between migrant women and native Danish women. The stage is used as a clinical indicator of access to healthcare until the point of diagnosis. Refugees and family reunited migrants who received residence permits in Denmark from 1 January 1993 to 31 December 1999 were included and matched 1 : 4 on age and sex with a Danish-born reference population. Our final female population included 24 734 migrants and 123 670 controls. Civil registration numbers of the cohort were linked to the Danish Cancer Registry whereby cases were identified in the period 1.1.1993-31.12.2002. Only women from Eastern Europe and the Middle East were included. This amounted to 269 migrants and 1608 native Danes. Data from the Danish Cancer Registry included diagnosis, time of diagnosis and disease stage at diagnosis. Our initial analyses of migrant subgroups showed that migrant women had decreased odds ratios of being diagnosed at the local stage and increased odds of having unknown stage, although these tendencies were mainly not statistically significant. A subsequent analysis of an overall migrant effect on all cancer sites emphasized these tendencies. This analysis reached borderline significance for local versus nonlocal stage and significance for unknown versus known stage. Our results indicate that migrant women may experience barriers in access to healthcare until cancer diagnosis compared with Danish women. More research is, however, needed to confirm our results and to find out if they indicate general problems concerning migrants' access to healthcare in Denmark.

Prior work has examined the shape of the income-mortality association, but work has not compared gradients between countries. In this study, we focus on changes over time in the shape of income-mortality gradients for 4 Nordic countries during a period of rising income inequality. Context and time differentials in shape imply that the relationship between income and mortality is not fixed. Population-based cohort study of Denmark, Finland, Norway and Sweden. We collected data on individuals aged 25 or more in 1995 (n=12.98 million individuals, 0.84 million deaths) and 2003 (n=13.08 million individuals, 0.90 million deaths). We then examined the household size equivalised disposable income at the baseline year in relation to the rate of mortality in the following 5 years. A steep income gradient in mortality in men and women across all age groups except the oldest old in Denmark, Finland, Norway and Sweden. From the 1990s to 2000s mortality dropped, but generally more so in the upper part of the income distribution than in the lower part. As a consequence, the shape of the income gradient in mortality changed. The shift in the shape of the association was similar in all 4 countries. A non-linear gradient exists between income and mortality in most cases and because of a more rapid mortality decline among those with high income the income gradient has become steeper over time.

An overlap between obesity and asthma exists, and inflammatory cells in adipose tissue could drive the development of asthma. Comparison of adipose tissue gene expression among Inuit living in Greenland to those in Denmark provides an opportunity to assess how changes in adipose tissue inflammation can be modified by migration and diet. To examine mast cell and inflammatory markers in adipose tissue and the association with asthma. Two Inuit populations were recruited, one living in Greenland and another in Denmark. All underwent adipose subcutaneous biopsy, followed by clinical assessment of asthma, and measurement of AHR. Adipose tissue biopsies were homogenised, RNA extracted, and PCR was performed to determine the relative gene expression of mast cell (tryptase, chymase, CPA3) and inflammatory markers (IL-6, IL-1β, and CD163). Of the 1059 Greenlandic Inuit participants, 556 were living in Greenland and 6.4% had asthma. Asthma was increased in Denmark (9%) compared to Greenland (3.6%, p < 0.0001) and associated with increased adipose tissue IL-6 gene expression and increased BMI. There was no association between asthma and adipose tissue mast cell gene expression. Pro-inflammatory gene expression (IL-6, IL-1β) was higher in those living in Denmark, and with increasing BMI and dietary changes. The anti-inflammatory (M2) macrophage marker, CD163, was higher in Greenland-dwelling Inuit (p < 0.01). No association was found between gene expression of mast cell markers in adipose tissue and asthma. Among Greenlandic Inuit, adipose tissue inflammation is also increased in those who migrate to Denmark, possibly as a result of dietary changes. Copyright © 2015 Elsevier Ltd. All rights reserved.

Objective To determine the quantity and quality of articles in the field of knee arthroplasty worldwide and elucidate the characteristics of global scientific production. Methods Web of Science was used to identify articles in the field of knee arthroplasty from 2011 to 2015. The total number of papers, number of papers per capita, total number of citations, and mean number of citations were collected. Results In total, 11,590 papers were identified. The number of publications significantly increased from 2011 to 2015. Most originated from North America, East Asia, and West Europe. Most (88.51%) were from high-income countries, 11.48% were from middle-income countries, and only 0.01% were from lower-income countries. The United States had the most articles and total citations. Sweden had the highest mean citations, followed by Denmark and Canada. However, when adjusted by population size, Denmark had the most articles per million population, followed by Switzerland and the Netherlands. Conclusions The number of knee arthroplasty publications has rapidly increased in recent years. The United States is the most prolific, but some European countries are more productive relative to their population.

Denmark is one of the countries where Human papillomavirus (HPV)-vaccination at present includes only girls. However, the burden of HPV-related cancer in men is increasing, which would argue for gender-neutral vaccination. The aim of this study was to examine the burden of HPV-caused cancers in women and men, and to evaluate the potential of HPV-vaccination in cancer control. Data were retrieved from the literature on population prevalence of high risk (HR) HPV, on HR HPV-prevalence and genotypes in HPV-related cancers, and on number of cytology samples in cervical screening. Data on annual biopsies and conisations were retrieved from the Danish National Health Service Register and the Danish National Patient Register. Incidences of HPV-related cancers in Denmark were extracted from NORDCAN. Number of HPV-caused cancers was calculated from number of HPV-related cancers and the proportion known to be caused by high-risk (HR) HPV. In cross-sectional surveys in Denmark, one fifth of women and almost one third of men were found to be positive for HR HPV. Per year, 548 HPV-caused cancer cases were diagnosed in women and 234 in men, and twice as many cancers in women as in men were preventable with HPV vaccination. However, including screening prevented cervical cancers, the burden of cancers caused by HPV-infection would be 1300-2000 in women as compared to 234 in men. Taking screening prevented cervical cancers into account, the cancer control potential of HPV-vaccination is considerably higher in women than in men. HPV-vaccination could reduce the burden of screening on women and on health care resources. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

There is a considerable interest in the possible relationship between psychosocial factors and the onset of breast cancer. This cohort study was based upon two nationwide and population-based central registers: The Danish Psychiatric Central Register, which contains all cases of psychiatric admissions, and The Danish Cancer Registry, which contains all cases of cancer. The register-linkage was accomplished by using a personal identification number. The study population comprised all women admitted to psychiatric departments or psychiatric hospitals in Denmark between 1969 and 1993 with an affective or a neurotic disorder. Overall, 66 648 women comprising 199 910 admissions and 775 522 person-years were included. The incidence of breast cancer in the cohort was compared with the national breast cancer incidence rates adjusted for age and calendar time. In all, 1270 women with affective or neurotic disorders developed breast cancer subsequent to the first admission as compared with the 1242 women expected, standardized incidence ratio (SIR) = 1.02 (95% confidence interval 0.97–1.08). None of the hypothetical risk factors: type of diagnosis, age or calendar period at cohort entry, age at breast cancer, alcohol abuse, alcohol/drug abuse without further specification, total number of admissions, total length of admissions, or time from first admission showed a statistically significant effect on the relative risk of breast cancer. We found no support for the hypothesis that women admitted to a psychiatric department with an affective or a neurotic disorder subsequently have an increased risk of breast cancer. © 1999 Cancer Research Campaign PMID:10555767

Background To integrate immigrants into their societies, European countries have adopted different types of policies, which may influence health through both material and psychosocial determinants. Recent studies have suggested poorer health outcomes for immigrants living in countries with poorly rated integration policies. Objective To analyse mortality differences of immigrants from the same country of origin living in countries with distinct integration policy contexts. Methods From the mortality dataset collected in the Migrant Ethnic Health Observatory (MEHO) project, we chose the Netherlands (linked data from 1996-2006), France (unlinked; 2005-2007) and Denmark (linked; 1992-2001) as representatives of the inclusive, assimilationist and exclusionist policy models, respectively, based on the Migrant Integration Policy Index. We calculated for each country sex- and age-standardized mortality rates for Turkish-, Moroccan- and local-born populations aged 20-69 years. Poisson regression was used to estimate the mortality rate ratios (MRRs) for cross-country and within-country comparisons. The analyses were further stratified by age group and cause of death. Results Compared with their peers in the Netherlands, Turkish-born immigrants had higher all-cause mortality in Denmark (MRR men 1.92; 95% CI 1.74-2.13 and women 2.11; 1.80-2.47) but lower in France (men 0.64; 0.59-0.69 and women 0.58; 0.51-0.67). A similar pattern emerged for Moroccan-born immigrants. The relative differences between immigrants and the local-born population were also largest in Denmark and lowest in France (e.g., Turkish-born men MRR 1.52; 95% CI 1.38-1.67 and 0.62; 0.58-0.66, respectively). These patterns were consistent across all age groups, and more marked for cardiovascular diseases. Conclusions Although confounders and data comparability issues (e.g., French cross-sectional data) may affect the findings, this study suggests that different macro-level policy contexts may influence immigrants’ mortality. Comparable mortality registration systems across Europe along with detailed socio-demographic information on immigrants may help to better assess this association. PMID:26067249

Herpes zoster (HZ) is a vaccine-preventable disease caused by reactivation of the varicella-zoster virus. Unfortunately, formulation of recommendations on routine immunization is hampered by a lack of data on disease burden, since most countries do not record cases of HZ in the general population. We developed and validated an algorithm to identify HZ based on routinely collected registry data and used it to quantify HZ occurrence and risk factors in Denmark prior to marketing of the HZ vaccine. We included patients aged ≥40years with a first-time systemic Acyclovir, Valacyclovir, or Famciclovir prescription or a hospital-based HZ diagnosis in the Danish nationwide health registries during 1997-2013. In a validation substudy (n=176), we computed the proportion of persons with HZ among patients who redeemed antiviral prescriptions. In a cohort study, we computed age-specific rates of HZ (45,297,258 person-years). In a case-control study, we then computed odds ratios (ORs) for common chronic diseases and immunosuppressive factors among HZ cases (n=189,025) vs. matched population controls (n=945,111). Medical record review confirmed HZ in 87% (95% confidence interval: 79-93%) of persons ≥40years who dispensed antivirals at doses recommended for HZ. HZ rates increased from 2.15/1000 person-years in 40-year-olds to 9.45/1000 person-years in 95-year-olds. Rates were highest in women. HZ was diagnosed during hospitalization among 3.5%. As expected, persons with severe immunosuppressive conditions had the highest ORs of HZ (between 1.82 and 4.12), but various autoimmune diseases, asthma, chronic kidney disease, and inhaled glucocorticoids were also associated with increased ORs (between 1.06 and 1.64). This algorithm is a valid tool for identifying HZ in routine healthcare data. It shows that HZ is common in Denmark, especially in patients with certain chronic conditions. Prioritized vaccination of such high-risk patients might be an option in countries considering alternatives to universal vaccination. Copyright © 2017 Elsevier Ltd. All rights reserved.

Current EU regulation requires that every bovine carcass is examined for bovine cysticercosis (BC) at meat inspection. This is costly and might be superfluous at low BC prevalence. However, from a consumer view-point it may be important to identify and manage infected carcasses to avoid human infection. If relevant data could be effectively used to classify animals with respect to their risk of being infected, then the current meat inspection could be replaced by a more cost-effective system targeting high-risk animals. This study aimed to (1) describe the distribution of BC cases in the Danish cattle population, (2) estimate the animal level prevalence (3) provide descriptive statistics of potential risk factors for BC, and (4) determine attributable risks and fractions of selected risk factors potentially useful for a future risk-based meat inspection system. In total, 348 cases of BC were recorded among all cattle slaughtered (n=4,090,661) in Denmark between 2004 and 2011. The true animal level prevalence of BC was estimated to be 0.06%. The herd of origin of the cases were defined as the herd in which the animals spent most of their lifetimes. The detected cases were found to originate from 328 herds, with a maximum of two cases per herd indicating sporadic occurrence. Even though organic farming was associated with a higher risk (RR=1.9 in univariable analysis) of BC-positive animals being detected at slaughter, the population attributable fraction showed that only 5% of the animals with BC could be attributed to organic farming practices at the level of organic farming practiced in Denmark in the study period. Thus, organic farming status was not a suitable risk factor to use to target future risk-based meat inspection. However, 54% of the animals with BC in the cattle population were attributed to female gender. Increasing age at slaughter was also associated with high risk of BC. There may be overlaps between these effects in animals with multiple risk factors. Other underlying factors such as grazing patterns might explain the risk factors and attribution results found in this study. However, grazing practices are currently not recorded in the Danish cattle database. Therefore, animal level risk factors such as age and gender together with other risk factors such as grazing practices might be included as food chain information, required to be provided by the farmer prior to slaughter. The challenges and opportunities of this approach should be investigated further. Copyright © 2012 Elsevier B.V. All rights reserved.

Microbiology, Redox and Contaminat Fate in the Grindsted Landfill Leachate Plume - A Summary of 25 Years of work

The contamination by leachate of the upper aquifer at the Grindsted Landfill (Denmark) stretches about 300 m downgradient from the landfill. The plume has been described with respect to water chemistry, sediment chemistry, pollutant distribution, microbial counts, PLFA and redox rates determined by unamended bioassays. This presentation summaries the findings and discusses unanswered questions. The landfill was active from 1930 to the mid 1970 and has no engineered leachate collection system. Leachate from municipal as well as from industrial waste has entered the aquifer for more than thirty years. The redox conditions change from strongly anaerobic (methanogenic, sulfate reducing, iron reducing) close to the landfill over manganese reduction and denitrification to aerobic conditions in the outskirts of the plume The redox conditions were determined from groundwater sample composition, hydrogen concentrations and sediment chemistry. The plume showed strong attenuation of aromatic compounds within the first 100 m downgradient of the landfill. Degradation experiments (batch, in-situ testers, long term field injection experiments) could not fully document degradation of all the compounds. MPN-measurements of methanogens, sulfate-reducers, iron-reducers, manganese-reducers and denitrifiers showed abundance of all groups with a slight trend with the redox conditions. PLFA measurements did not provide much insight into the microbial populations of the plume, but confirmed some previous observations. Bioassays gave estimates of the rates of the various redox processes, but showed for some samples more simultaneous redox processes. More than 25 years of work has been put into the Grindsted Landfill leachate plume. References Bjerg, P.L., Rugge, K., Cortsen, J., Nielsen, P.H. & Christensen, T.H.

Little is known about the role of heritable factors in diverticular disease. We evaluated the contribution of heritable factors to the development of diverticular disease diagnosed at a hospitalization or outpatient visit. Using nationwide patient registries, we identified 142,123 incident cases of diverticular disease diagnosed at a hospitalization (1977-2011) or an outpatient hospital visit (1995-2011) in Denmark, including cases in 10,420 index siblings and 923 twins. We calculated standardized incidence ratios for siblings versus the general population and concordance rates for monozygotic versus dizygotic twin pairs as measures of relative risk (RR). The RR for diverticular disease in siblings of index cases was 2.92 (95% confidence interval [CI], 2.50-3.39) compared with the general population. The RRs were similar irrespective of the sex of the sibling or index case and were particularly strong in siblings of hospitalized cases and cases that underwent surgery. The proband-wise concordance rate for monozygotic twins was double that of dizygotic twins (0.16 [95% CI, 0.11-0.22] vs 0.07 [95% CI, 0.05-0.11], respectively). The RR of diverticular disease in one twin when the other had diverticular disease was 14.5 (95% CI, 8.9-23) for monozygotic twins compared with 5.5 (95% CI, 3.3-8.6) for dizygotic twins. Associations were stronger in female monozygotic twins compared with male twins (tetrachoric correlation, 0.60 [95% CI, 0.49-0.70] vs 0.33 [95% CI, 0.13-0.51]; P = .03 in an analysis stratified by sex and zygosity). We estimate that 53% (95% CI, 45%-61%) of susceptibility to diverticular disease results from genetic factors. Based on a population-based study in Denmark, genetic factors appear to contribute to development of diverticular disease. Copyright © 2013 AGA Institute. Published by Elsevier Inc.

Nosocomial infections with Clostridium difficile present a considerable problem despite numerous attempts by health care workers to reduce risk of transmission. Asymptomatic carriers of C difficile can spread their infection to other patients. We investigated the effects of asymptomatic carriers on nosocomial C difficile infections. We performed a population-based prospective cohort study at 2 university hospitals in Denmark, screening all patients for toxigenic C difficile in the intestine upon admittance, from October 1, 2012, to January 31, 2013. Screening results were blinded to patients, staff, and researchers. Patients were followed during their hospital stay by daily registration of wards and patient rooms. The primary outcomes were rate of C difficile infection in exposed and unexposed patients and factors associated with transmission. C difficile infection was detected in 2.6% of patients not exposed to carriers and in 4.6% of patients exposed to asymptomatic carriers at the ward level (odds ratio for infection if exposed to carrier, 1.79; 95% confidence interval, 1.16-2.76). Amount of exposure correlated with risk of C difficile infection, from 2.2% in the lowest quartile to 4.2% in the highest quartile of exposed patients (P = .026). Combining the load of exposure to carriers and length of stay seemed to have an additive effect on the risk of contracting C difficile. In a population-based prospective cohort study in Denmark, we found that asymptomatic carriers of toxigenic C difficile in hospitals increase risk of infection in other patients.

Paleopathological studies of leprosy in Danish skeletal collections show that many individuals suffered from this stigmatized disease during the Middle Ages. This study examines the risk of death associated with leprotic infection in individuals from the Danish rural cemetery of Øm Kloster (AD 1172-1536). Specifically, we modeled the influence of leprotic infection on age-specific mortality accounting also for sex and social status (lay person / monastic). The sample consisted of 311 adult individuals from the Øm Kloster skeletal collection housed at the Institute of Forensic Medicine, University of Southern Denmark (ADBOU). We modeled morbidity and mortality using a three-state illness-death model with the following parameterizations for the three transition hazards: (1) nonlesioned to lesioned: constant; (2) nonlesioned to dead: Gompertz-Makeham; and (3) lesioned to dead: Gompertz-Makeham, directly proportional to the hazard of the well to dead transition. The mortality hazard of lesioned individuals exceeded that of nonlesioned individuals by a factor of 1.4 (40%) across all individuals, 1.7 for females, 1.0 for males, 1.3 for lay persons, and 1.7 for monastics. Overall, 15% of the sample died with skeletal manifestations of leprosy, though it is likely that a higher percentage of the population carried the bacterium. This study improves understanding of past health and population dynamics focusing on a chronic infectious disease. The methods employed could informatively be applied to larger analyses of community health from skeletal collections by incorporating more than one disease into the multistate model and inferring individual frailty using various skeletal markers. © 2017 Wiley Periodicals, Inc.

Objective The prognosis for colon and rectal cancer has improved in Denmark over the past decades but is still poor compared with that in our neighboring countries. We conducted this population-based study to monitor recent trends in colon and rectal cancer survival in the central and northern regions of Denmark. Material and methods Using the Danish National Registry of Patients, we identified 9412 patients with an incident diagnosis of colon cancer and 5685 patients diagnosed with rectal cancer between 1998 and 2009. We determined survival, and used Cox proportional hazard regression analysis to compare mortality over time, adjusting for age and gender. Among surgically treated patients, we computed 30-day mortality and corresponding mortality rate ratios (MRRs). Results The annual numbers of colon and rectal cancer increased from 1998 through 2009. For colon cancer, 1-year survival improved from 65% to 70%, and 5-year survival improved from 37% to 43%. For rectal cancer, 1-year survival improved from 73% to 78%, and 5-year survival improved from 39% to 47%. Men aged 80+ showed most pronounced improvements. The 1- and 5-year adjusted MRRs decreased: for colon cancer 0.83 (95% confidence interval CI: 0.76–0.92) and 0.84 (95% CI: 0.78–0.90) respectively; for rectal cancer 0.79 (95% CI: 0.68–0.91) and 0.81 (95% CI: 0.73–0.89) respectively. The 30-day postoperative mortality after resection also declined over the study period. Compared with 1998–2000 the 30-day MRRs in 2007–2009 were 0.68 (95% CI: 0.53–0.87) for colon cancer and 0.59 (95% CI: 0.37–0.96) for rectal cancer. Conclusion The survival after colon and rectal cancer has improved in central and northern Denmark during the 1998–2009 period, as well as the 30-day postoperative mortality. PMID:21814467

How many neurosurgeons do we want to educate in Europe annually? The Danish proposal.

PubMed

Gjerris, F; Madsen, F F

The neurosurgical population consists of professors, consultants, specialised senior registrars, and doctors in training (senior registrars, trainees and young doctors to be educated as neurosurgeons). Knowing number and size of the neurosurgical departments in each European country, the number of staff members, the politics of retirement (age, educational level) and the age of every neurosurgeon it is possible to calculate the exact number of trainees needed per year to maintain a state of balance in every single European country. With Denmark as a model we based our assessments partly on a simple calculation model of the exact annual number of neurosurgical trainees or senior registrars and partly used an actuary flow model for calculation. In Denmark with 5 neurosurgical departments, 5.2 mill. population and a retirement age of 70, we have an average of 1-2 newcomers per year and maintain a bulk of 10 senior registrars in education. Thus there will be a balance between intake of newcomers and retirement, of course with some unknown factors as unforeseen dismissal or resignation, death rate among neurosurgeons and transfer to private practice.

The objective of this study was to find out the number of publications (in Danish) and research projects (including grey literature) either carried out or ongoing within the field of public health in Denmark, using the same criteria as the SPHERE project, but looking at Danish research databases. The Danish research database served as the main resource for the study supported by national research reports. There is an increasing trend in the number of public health research projects and publications. Compared with public health research projects published in English there are differences in some categories. Overall, public health research in Denmark seems to contribute around 4.8%-6.5% of the total amount of health research. Public health research has a relatively low share of overall health research in Denmark.

Social relations and healthcare utilisation among middle-aged and older people: study protocol for an implementation and register-based study in Denmark.

While previous research establishes an association between social relations, health and use of healthcare services among older people, how to implement this knowledge in real-life settings has received much less attention. This study will explore the relationship between social relations, health and use of healthcare services in a Danish mid-life population sample. In addition, the study will explore individual and contextual factors affecting the implementation of a group-based life story intervention aimed at establishing and strengthening social relations among older people at nursing homes in Denmark. A combined quantitative register-based approach and a qualitative implementation approach will be applied in this study. First, we will quantitatively analyse the relationship between social relations, health status and use of healthcare services among middle-aged people in Denmark by linking survey data on social relations, loneliness, self-perceived health and disease status from the Copenhagen Aging and Midlife Biobank (CAMB) (n = 7191) with national registries through the Public Health Database on use of healthcare services and demographic and socioeconomic factors. Second, we will qualitatively analyse individual and contextual factors affecting the implementation process of the group-based life story intervention based on semi-structured interviews (n = 16), observations and field notes with and among intervention stakeholders, i.e., participants and group leaders facilitating the intervention. The results of this study are expected to improve knowledge about mechanisms through which social relations are associated with health status and use of healthcare services and to inform the implementation of future interventions targeting social relations among older people at nursing homes. The study has been registered and approved by the Danish Data Protection Agency. Seperate approvals have been attained for the qualitative data (Approval No. SUND-2016-08), and for the quantitative data in the CAMB database which has also received approval from the local ethical committee (approval No.H-A-2008-126 and No. 2013-41-1814, respectively).

Large population-based studies are needed to examine the effect of maternal use of fertility drugs on the risk of cancer in children, while taking into account the effect of the underlying infertility. A cohort of 123,322 children born in Denmark between 1964 and 2006 to 68,255 women who had been evaluated for infertility was established. We used a case-cohort design and calculated hazard ratios (HRs) for cancer in childhood (0-19 years) and in young adulthood (20-29 years) associated with maternal use of six groups of fertility drugs (clomiphene, gonadotropins [i.e., human menopausal gonadotropins and follicle-stimulating hormone], gonadotropin-releasing hormone analogs, human chorionic gonadotropins, progesterone and other fertility drugs). We found no statistically significant association between maternal use of fertility drugs and risk for overall cancer in childhood or young adulthood. However, with regard to specific cancers in childhood, our results showed that maternal use of progesterone before childbirth markedly increased the risks of their offspring for acute lymphocytic leukemia (any use: HR, 4.95; 95% CI, 1.69-14.54; ≥ three cycles of use: HR, 9.96; 95% CI, 2.63-37.77) and for sympathetic nervous system tumors (any use: HR, 5.79; 95% CI, 1.23-27.24; ≥ three cycles of use: HR, 8.51; 95% CI, 1.72-42.19). These findings show that maternal use of progesterone may increase the risk for specific cancers in the offspring. Additional large epidemiological studies are urgently needed to confirm our finding. © 2014 UICC.

This study explores concerns and dilemmas connected with diet, health and child-feeding in families with ethnic minority background. The aim is to contribute to better targeting of dietary advice to ethnic minority parents in Denmark. Four focus group interviews were carried out with mothers of children between 4 months and 2 and a half years who were descendants of Turkish or Pakistani immigrants. The focus groups investigated: (1) everyday feeding practices; (2) values and concerns behind food choice; (3) social and cultural norms influencing feeding and eating practices; (4) experienced dilemmas in dietary change; and (5) sources of nutritional advice. Public health authorities in Denmark tend to link diet-related health problems among ethnic minority populations with their ethnic identity, dichotomising ethnic and Danish dietary habits. This may overlook values and concerns other than those related to ethnicity that are sometimes more important in determining food habits. The present study found that child-feeding practices were shaped by two main aims: (1) securing and improving child health; and (2) ensuring multi-cultural eating competence in children. The results confirm that ethnic distinctions do matter in the concerns and dilemmas mothers experience when feeding their children, but they also challenge the health authorities' reliance on dichotomies in promoting health among immigrant families. The participants' ethnic self-identification through food practices did not refer primarily to the birthplaces of their parents. Rather, it was context dependent and directed simultaneously towards majority and minority culture. © 2013 John Wiley & Sons Ltd.

A substantial amount of refugees (10-30%) suffer from Post-Traumatic Stress Disorder (PTSD). In Denmark there are different facilities specialised in psychiatric treatment of trauma-affected refugees. A previously published case report from such a facility in Denmark shows that some patients suffer from secondary psychotic symptoms alongside their PTSD. The aim of this study was to illustrate the characteristics and estimate the prevalence of psychotic features in a clinical population of trauma-affected refugees with PTSD. Psychiatric records from 220 consecutive patients at Competence Centre for Transcultural Psychiatry (CTP) were examined, and all the PTSD patients were divided into two groups; one group with secondary psychotic features (PTSD-SP group) and one without (PTSD group). A categorisation and description of the secondary psychotic features was undertaken. One hundred eighty-one patients were diagnosed with PTSD among which psychotic symptoms were identified in 74 (40.9, 95% CI 33.7-48.1%). The majority of symptoms identified were auditory hallucinations (66.2%) and persecutory delusions (50.0%). There were significantly more patients diagnosed with enduring personality change after catastrophic experience in the PTSD-SP group than in the PTSD group (P = 0.009). Furthermore the PTSD-SP group included significantly more patients exposed to torture (P = 0.001) and imprisonment (P = 0.005). This study provides an estimation of PTSD-SP prevalence in a clinical refugee population with PTSD. The study points to the difficulties distinguishing psychotic features from flashbacks and the authors call for attention to psychotic features in PTSD patients in order to improve documentation and understanding of the disorder.

Hepatitis B virus (HBV) infection is common in Arctic populations and high alcohol intake has been associated with an increased risk of a number of diseases. Yet, a description of the influence of alcohol intake in persons with HBV infection on liver biochemistry is lacking. We aimed to describe the association between reported alcohol intake and liver biochemistry taking into account also HBV infection, ethnicity, Inuit diet, body mass index (BMI), gender and age in an Arctic population. Population-based investigation of Inuit (n=441) and non-Inuit (94) in Greenland and Inuit living in Denmark (n=136). Participants filled in a questionnaire on alcohol intake and other life style factors. Blood samples were tested for aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), bilirubin, albumin, hepatitis B surface antigen, hepatitis B surface antibody and hepatitis B core antibody. We also performed physical examinations. Participation rate was 95% in Greenland and 52% in Denmark. An alcohol intake above the recommended level was reported by 12.9% of non-Inuit in Greenland, 9.1% of Inuit in East Greenland, 6.1% of Inuit migrants and 3.4% of Inuit in the capital of Greenland (p=0.035). Alcohol intake was associated with AST (p<0.001) and GGT (p=0.001), and HBV infection was associated with ALP (p=0.001) but not with AST, GGT, bilirubin or albumin in the adjusted analysis. Inuit had higher AST (p<0.001), GGT (p<0.001) and ALP (p=0.001) values than non-Inuit after adjustment for alcohol, diet, BMI and HBV exposure. Ethnic origin modified the association between alcohol and AST, while HBV infection did not modify the associations between alcohol and liver biochemistry. Non-Inuit in Greenland reported a higher alcohol intake than Inuit. Ethnic origin was more markedly associated with liver biochemistry than was alcohol intake, and Greenlandic ethnicity modified the effect of alcohol intake on AST. HBV infection was slightly associated with ALP but not with other liver biochemistry parameters.

This study examined the possible association between agricultural and horticultural work and the subsequent morbidity of Parkinson's disease. Fixed cohorts of 2,273,872 men and women aged 20-59 years on 1 January 1981 and identified in the Central Population Register of Denmark were followed, and all first-time hospitalizations with Parkinson's disease as the principal diagnosis during the 13 years until 31 December 1993 were recorded. Standardized hospitalization ratios (SHR) were calculated using all gainfully employed persons as the standard and by multiplying the ratio by 100. Ninety-five percent confidence intervals (95% CI) were calculated on the assumption of a Poisson distribution. A high risk of Parkinson's disease was found for the men and women in agriculture and horticulture (134 cases, SHR 132, 95% CI 111-156). Statistically significantly high risks were found for farmers (79 cases, SHR 130, 95% CI 103-163) and for all men in agriculture and horticulture (109 cases, SHR 134, 95% CI 109-162). A consistent pattern of high Parkinson's disease morbidity was found among occupational groups employed in agriculture and horticulture.

Exposure to secondhand smoke is associated with an increased risk of acute myocardial infarction (AMI). The positive impact of a smoking ban on AMI hospitalization rates has been demonstrated both inside and outside Europe. A national smoking ban (SB) was implemented in Denmark on 15 August 2007. To evaluate the impact of the Danish SB on hospital admissions for AMI. Poisson regression models were used to analyse changes over time in AMI-admissions in Denmark. We investigated a seven year period: five years before and two years after implementation of the SB. We accounted for the variation in the population size and for seasonal trends. Potential confounders included were: gender, age and the incidence of type 2 diabetes (T2D). A significant reduction in the number of AMI-admissions was found in the last three years of the study period after adjusting for the potential confounders. The significant reductions were found one year before the SB (relative rate (RR) = 0.86, 95% confidence interval (CI) 0.79-0.94), one year after the SB (RR = 0.77, 95% CI 0.71-0.85) and two years after the SB (RR = 0.77, 95% CI 0.70-0.84). A significant reduction in the number of AMI-admissions was found already one year before the SB after adjustment for the incidence of T2D. The results differ from most results found in similar studies throughout the world and may be explained by the incremental enactment of SBs in Denmark and the implementation of a nation-wide ban on industrially produced trans-fatty acids in food in 2004.

Sea sandwort (Honckenya peploides) was one of the first plants to successfully colonize and reproduce on the volcanic island Surtsey, formed in 1963 off the southern coast of Iceland. Using amplified fragment length polymorphic (AFLP) markers, we examined levels of genetic variation and differentiation among populations of H. peploides on Surtsey in relation to populations on the nearby island Heimaey and from the southern coast of Iceland. Selected populations from Denmark and Greenland were used for comparison. In addition, we tested whether the effects of isolation by distance could be seen in the Surtsey populations. Using two primer combinations, we obtained 173 AFLP markers from a total of 347 plant samples. The resulting binary matrix was then analysed statistically. The main results include the following: (i) Surtsey had the highest proportion of polymorphic markers as well as a comparatively high genetic diversity (55.5% proportion of polymorphic loci, PLP; 0.1974 HE) and Denmark the lowest (31.8% PLP; 0.132 HE), indicating rapid expansion during an early stage of population establishment on Surtsey and/or multiple origins of immigrants; (ii) the total genetic differentiation (FST) among Surtsey (0.0714) and Heimaey (0.055) populations was less than half of that found among the mainland populations in Iceland (0.1747), indicating substantial gene flow on the islands; (iii) most of the genetic variation (79%, p < 0.001) was found within localities, possibly due to the outcrossing and subdioecious nature of the species; (iv) a significant genetic distance was found within Surtsey, among sites, and this appeared to correlate with the age of plant colonization; and (v) the genetic structure analysis indicated multiple colonization episodes on Surtsey, whereby H. peploides most likely immigrated from the nearby island of Heimaey and directly from the southern coast of Iceland.

Profiling drunk driving recidivists in Denmark.

PubMed

Møller, Mette; Haustein, Sonja; Prato, Carlo Giacomo

2015-10-01

Drunk drivers are a menace to themselves and to other road users, as drunk driving significantly increases the risk of involvement in road accidents and the probability of severe or fatal injuries. Although injuries and fatalities related to road accidents have decreased in recent decades, the prevalence of drunk driving among drivers killed in road accidents has remained stable, at around 25% or more during the past 10 years. Understanding drunk driving, and in particular, recidivism, is essential for designing effective countermeasures, and accordingly, the present study aims at identifying the differences between non-drunk drivers, drunk driving non-recidivists and drunk driving recidivists with respect to their demographic and socio-economic characteristics, road accident involvement and other traffic and non-traffic-related law violations. This study is based on register-data from Statistics Denmark and includes information from 2008 to 2012 for the entire population, aged 18 or older, of Denmark. The results from univariate and multivariate statistical analyses reveal a five year prevalence of 17% for drunk driving recidivism, and a significant relation between recidivism and the drunk drivers' gender, age, income, education, receipt of an early retirement pension, household type, and residential area. Moreover, recidivists are found to have a higher involvement in alcohol-related road accidents, as well as other traffic and, in particular, non-traffic-related offences. These findings indicate that drunk driving recidivism is more likely to occur among persons who are in situations of socio-economic disadvantage and marginalisation. Thus, to increase their effectiveness, preventive measures aiming to reduce drunk driving should also address issues related to the general life situations of the drunk driving recidivists that contribute to an increased risk of drunk driving recidivism.

Normal progress of labor is a subject for discussion among professionals. The aim of this study was to assess the duration of labor in women with a planned home birth and spontaneous onset who gave birth at home or in hospital after transfer. This is a population-based study of home births in four Nordic countries (Denmark, Iceland, Norway, and Sweden). All midwives assisting at a home birth from 2008 to 2013 were asked to provide information about home births using a questionnaire. Birth data from 1,612 women, from Denmark (n = 1,170), Norway (n = 263), Sweden (n = 138), and Iceland (n = 41) were included. The total median duration from onset of labor until the birth of the baby was approximately 14 hours for primiparas and 7.25 hours for multiparas. The duration of the different phases varied between countries. Blood loss more than 1,000 mL and perineal ruptures that needed suturing were associated with a longer pushing phase and the latter with country of residence, parity, single status, and the baby's weight. In this population of healthy women with a low prevalence of interventions, the total duration of labor was fairly similar to what is described in the literature for multiparas, but longer for primiparas. Although the duration of the phases of labor differed among countries, it was to a minor extent associated with severe outcomes. © 2015 Wiley Periodicals, Inc.

The aetiology of childhood cancer remains largely unknown but recent research indicates that uterine environment plays an important role. We aimed to examine the association between the Apgar score at 5 min after birth and the risk of childhood cancer. Nationwide population-based cohort study. Nationwide register data in Denmark and Sweden. All live-born singletons born in Denmark from 1978 to 2006 (N=1 771 615) and in Sweden from 1973 to 2006 (N=3 319 573). Children were followed up from birth to 14 years of age. Rates and HRs for all childhood cancers and for specific childhood cancers. A total of 8087 children received a cancer diagnosis (1.6 per 1000). Compared to children with a 5-min Apgar score of 9-10, children with a score of 0-5 had a 46% higher risk of cancer (adjusted HR 1.46, 95% CI 1.15 to 1.89). The potential effect of low Apgar score on overall cancer risk was mostly confined to children diagnosed before 6 months of age. Children with an Apgar score of 0-5 had higher risks for several specific childhood cancers including Wilms' tumour (HR 4.33, 95% CI 2.42 to 7.73). A low 5 min Apgar score was associated with a higher risk of childhood cancers diagnosed shortly after birth. Our data suggest that environmental factors operating before or during delivery may play a role on the development of several specific childhood cancers.

Similar to the thalassaemia syndromes, glucose-6-phosphate dehydrogenase (G6PD) deficiency is highly prevalent in areas historically exposed to malaria. In the present study, we used quantitative and molecular methods to determine the prevalence of G6PD deficiency in a population of 1508 immigrants in Denmark. We found the allele frequency to be between 2.4 and 2.9% in the female immigrants. Furthermore, the mutation pattern in the studied population showed a high prevalence of the G6PD A-(202A) variant in African and African-American immigrants, a high prevalence of the G6PD Mediterranean variant in Mediterranean European and Western Asian immigrants, and substantial heterogeneity in the variants found in the Eastern Asian/Pacific immigrants. Inasmuch as many of the patients included in this investigation had various thalassaemic syndromes, we were able to evaluate the effects of the interaction between a low mean corpuscular haemoglobin (MCH) value and G6PD activity, particularly in heterozygous females. The activity level was markedly influenced by the MCH value in females with normal G6PD activity, but not in heterozygous and homozygous females. Comparison of patients with normal G6PD activity and heterozygous females indicated considerable overlap in activity levels. To help separating heterozygous females from females with wild-type genes, a DNA analysis is necessary when the female activity level is between 4.0 and 4.9 U/g hgb corresponding to 50-60% of the median activity of unaffected males.

In patients with lower respiratory tract infections (LRTIs) it is a challenge to identify who should be treated with antibiotics. According to international guidelines, antibiotics should be prescribed to patients with suspected pneumonia while acute bronchitis is considered a viral infection and should, generally, not be treated with antibiotics. Overdiagnosis of pneumonia in patients with LRTIs may lead to antibiotic overprescribing. To investigate the prevalence of presumed pneumonia in patients with LRTI in two countries with different antibiotic prescribing rates (Denmark and Spain) and to compare which symptoms and clinical tests are of most importance for the GP when choosing a diagnosis of pneumonia rather than acute bronchitis. A cross-sectional study including GPs from Denmark and Spain was conducted as part of the EU-funded project HAPPY AUDIT. A total of 2,698 patients with LRTI were included. In Denmark, 47% of the patients with LRTI were classified with a diagnosis of pneumonia compared with 11% in Spain. In Spain, fever and a positive x-ray weighted significantly more in the diagnosis of pneumonia than in Denmark. Danish GPs, however, attached more importance to dyspnoea/polypnoea and C-reactive protein levels >50mg/L. None of the other typical symptoms of pneumonia had a significant influence. Our results indicate that GPs' diagnostic criteria for pneumonia differ substantially between Denmark and Spain. The high prevalence of pneumonia among Danish patients with LRTI may indicate overdiagnosis of pneumonia which, in turn, may lead to antibiotic overprescribing.

Objectives This study aimed to examine whether occupational and physical activity (PA) at different ages contribute to Parkinson's disease (PD) risk in a large population-based case-control study in Denmark. Methods We identified 1828 PD patients from the Danish National Hospital Register and recruited 1909 gender and year of birth matched controls from the Danish Central Population Register. Occupational and leisure-time PA were determined from a job exposure matrix based on occupational history and self-reported leisure-time information. Results No association was found for occupational PA alone in men, but higher leisure-time PA (≥5 hours/week of strenuous activities) in young adulthood (15-25 years) was associated with a lower PD risk (adjusted odds ratio (OR adj ) 0.75, 95% confidence interval (95% CI) 0.62-0.90); men who engaged in high occupational and high leisure-time PA in young adulthood had the lowest PD risk (OR adj 0.58, 95% CI 0.41-0.81). Among women, inverse associations were found for occupation PA before age 50 (highest vs lowest, OR adj 0.75, 95% CI 0.55-1.06) and strenuous leisure-time PA after age 50 (OR adj 0.65, 95% CI 0.87-0.99); no clear pattern was seen for leisure and occupational PA combined. Conclusions We observed gender-specific inverse associations between occupational and leisure-time PA and PD risk; however, we cannot preclude reverse causation especially in older ages since PD has a long prodromal stage that might lead to a reduction of PA years before motor symptom onset and PD diagnosis.

Impacts of 21st century climate changes on flora and vegetation in Denmark

In this paper we examined the potential impacts of predicted climatic changes on the flora and vegetation in Denmark using data from a digital database on the natural vegetation of Europe. Climate scenarios A2 and B2 were used to find regions with present climatic conditions similar to Denmark's climate in the year 2100. The potential natural vegetation of Denmark today is predominantly deciduous forest that would cover more than 90% of the landscape. Swamps, bogs, and wet forest would be found under moist or wet conditions. Dwarf shrub heaths would be naturally occurring on poor soils along the coast together with dune systems and salt-marsh vegetation. When comparing the natural vegetation of Denmark to the vegetation of five future-climate analogue areas, the most obvious trend is a shift from deciduous to thermophilous broadleaved forest currently found in Southern and Eastern Europe. A total of 983 taxa were recorded for this study of which 539 were found in Denmark. The Sørensen index was used to measure the floristic similarity between Denmark and the five subregions. Deciduous forest, dwarf shrub heath, and coastal vegetation were treated in more detail, focusing on potential new immigrant species to Denmark. Finally, implications for management were discussed. The floristic similarity between Denmark and regions in Europe with a climate similar to what is expected for Denmark in year 2100 was found to vary between 48-78%, decreasing from North to South. Hence, it seems inevitable that climate changes of the magnitudes foreseen will alter the distribution of individual species and the composition of natural vegetation units. Changes, however, will not be immediate. Historic evidence shows a considerable lag in response to climatic change under natural conditions, but little is known about the effects of human land-use and pollution on this process. Facing such uncertainties we suggested that a dynamic strategy based on modeling, monitoring and adaptive management is adopted. Modeling techniques can be constantly improved, but will never be perfect and should therefore be linked to a fine-masked network of observatories to check model predictions and feed empirical data back into the models for calibration and further development.

Community-acquired pneumonia (CAP) is a severe infection, with high mortality. Antibiotic strategies for CAP differ across Europe. The objective of the study was to describe the epidemiology of CAP in Denmark and evaluate the prognosis of patients empirically treated with penicillin-G/V monotherapy. Retrospective cohort study including hospitalized patients with x-ray confirmed CAP. We calculated the population-based incidence, reviewed types of empiric antibiotics and duration of antibiotic treatment. We evaluated the association between mortality and treatment with empiric penicillin-G/V using logistic regression analysis. We included 1320 patients. The incidence of hospitalized CAP was 3.1/1000 inhabitants. Median age was 71 years (IQR; 58-81) and in-hospital mortality was 8%. Median duration of antibiotic treatment was 10 days (IQR; 8-12). In total 45% were treated with penicillin-G/V as empiric monotherapy and they did not have a higher mortality compared to patients treated with broader-spectrum antibiotics (OR 0.92, CI 95% 0.55-1.53). The duration of treatment exceeded recommendations in European guidelines. Empiric monotherapy with penicillin-G/V was commonly used and not associated with increased mortality in patients with mild to moderate pneumonia. Our results are in agreement with current conservative antibiotic strategy as outlined in the Danish guidelines.

Some economic consequences of an ageing and declining population in Denmark.

Figures for 1981 indicate that Denmark has a fertility level of 1.45 which has been below replacement level since 1968. In that same time period, natural increase has decreased from over 27,000 in 1968 to only 1354 in 1980 and a negative natural increase in 1981 with deaths outnumbering births by 3001. Even during the depression in the 1930's, net population increase was between 6-9/1000 with a fertility level which hovered around replacement level. At that time, the number of females in the childbearing ages was enough to provide population growth, whereas the number is much less today. Population increase is only 0.3/1000. The national population projections for Denmark for 1981-2010 assume an increase in the fertility level from 1.45-1.70 by 1991 after which it remains constant. The number of 20-39 year olds increased steadily until 1945 after which there was a decline as the cohorts from periods with low fertility levels entered this age group, but this was again followed by a steady increase to the present day. The number of females aged 0-39 years is expected to decrease in all age groups to the year 2000. Those aged 40-59 increased in numbers from 1920 to the mid 1960s, since then they have decreased in number, but an increase is forcast for the remainder of the century. The number of elderly females also increased steadily from 1930-80, from about 200,000 to over 550,000; this is expected to continue until 1990 when a short-term decline will set in. Regarding the economic and social consequences of these trends, it is shown that the present decline in fertility has its origins in a period of low unemployment and its negative growth while there was still relatively low unemployment and economic growth. In 1973 the unemployed rate was 0.9% of the work force and this rose to 9.2% in 1981. The Danish population has aged from one with 1/4 million people aged 60 and over at the turn of the century to about 1 million of that age today. Also, the aged themselves have aged so that the number of extreme aged (age 80 and over) has increased from 21,500 to 150,000 between 1901-81. In the last 20 years, elderly mortality, especially that of females, has decreased faster and more substantially than previously experienced and has led to absolute increases in the number of elderly that were unforeseen. From 1901-81, the old-age dependency ratio of those aged 60 and over to those aged 20-59 has almost doubled whereas the youth dependency dropped dramatically. From 1970-71 to 1980 old age pension payments in Denmark have risen from 5.3 billion crowns-17.9 billion, a rise of 13.2%. In the next 20 years the working and retired population will be unaffected by future fertility unless female labor force participation rates respond to changes. Mortality and international migration are the 2 demographic components that can have an effect. It therefore remains that investments in the younger generation are investments in the future.

Family history, place and season of birth as risk factors for schizophrenia in Denmark: a replication and reanalysis.

PubMed

Pedersen, C B; Mortensen, P B

2001-07-01

Although a family history of schizophrenia is the strongest individual risk factor for schizophrenia, environmental factors related to urbanicity may contribute to a substantial proportion of the population occurrence of the disease. This study replicates previous findings in four mutually exclusive Danish study populations, including out-patient information, ICD-10 diagnoses of schizophrenia, and a broader adjustment for mental illness in family members. We established a population-based cohort of 2.66 million Danish people using data from the Civil Registration System linked with the Psychiatric Case Register. Overall, 10 264 persons developed schizophrenia during the 50.7 million person-years of follow-up. The risk of schizophrenia was increased by urbanicity of place of birth and by family history of schizophrenia or other mental disorders. Urban-rural differences of schizophrenia risk were replicated and could not be associated with the potential sources of bias we assessed. Environmental factors underlying the effect of place of birth are major determinants of schizophrenia occurrence at the population level, although the effect of family history is the strongest at the individual level.

The incidence of inflammatory bowel disease (IBD) is record high in the Faroe Islands, and many Faroese emigrate to Denmark, where the IBD incidence is considerably lower. To study the IBD incidence in first-, second- and third-generation immigrants from the Faroe Islands to Denmark to assess the extent to which the immigrants adopt the lower IBD incidence of their new home country. Data on Faroese-born Danish residents and their children were retrieved from the Danish Central Population Register for 1980-2014. Incident IBD cases were identified from the Danish National Patient Register. Standardised Incidence Ratios (SIRs) were used to compare the IBD risk in immigrants with that of Danes. 95% confidence intervals (CI) were calculated using the square-root transform. First-generation Faroese immigrants had a higher IBD incidence than Danes, SIR 1.25 (95% CI, 0.97-1.59) for men and 1.28 (95% CI, 1.05-1.53) for women. This excess risk derived from ulcerative colitis (UC), SIR 1.44 (95% CI, 1.10-1.87) for men and 1.36 (95% CI, 1.09-1.68) for women. No excess risk was found for Crohn's disease (CD). The UC risk was nearly doubled during the immigrants' first 10 years in Denmark; SIR 2.13 (95% CI, 1.52-2.92) for men and 1.63 (95% CI, 1.19-2.18) for women. Although some impact of genetic dilution cannot be excluded, our findings indicate importance of gene-environment interplay in UC, as the excess UC risk in Faroese immigrants to Denmark disappeared over time and over one generation in men and over two generations in women. © 2017 The Authors.

We compared mitochondrial DNA and gill-raker number variation in populations of the European whitefish Coregonus lavaretus (L.) species complex to illuminate their evolutionary history, and discuss mechanisms behind diversification. Using single-strand conformation polymorphism (SSCP) and sequencing 528 bp of combined parts of the cytochrome oxidase b (cyt b) and NADH dehydrogenase subunit 3 (ND3) mithochondrial DNA (mtDNA) regions, we documented phylogeographic relationships among populations and phylogeny of mtDNA haplotypes. Demographic events behind geographical distribution of haplotypes were inferred using nested clade analysis (NCA) and mismatch distribution. Concordance between operational taxonomical groups, based on gill-raker numbers, and mtDNA patterns was tested. Three major mtDNA clades were resolved in Europe: a North European clade from northwest Russia to Denmark, a Siberian clade from the Arctic Sea to southwest Norway, and a South European clade from Denmark to the European Alps, reflecting occupation in different glacial refugia. Demographic events inferred from NCA were isolation by distance, range expansion, and fragmentation. Mismatch analysis suggested that clades which colonized Fennoscandia and the Alps expanded in population size 24 500-5800 years before present, with minute female effective population sizes, implying small founder populations during colonization. Gill-raker counts did not commensurate with hierarchical mtDNA clades, and poorly with haplotypes, suggesting recent origin of gill-raker variation. Whitefish designations based on gill-raker numbers were not associated with ancient clades. Lack of congruence in morphology and evolutionary lineages implies that the taxonomy of this species complex should be reconsidered.

Absolute risk and risk factors for recurrence and ovarian serous carcinoma following ovarian serous borderline tumors (SBTs) is not well-established. We included all women with SBTs in Denmark, 1978-2002. Diagnoses were confirmed by centralized pathology review and classified as atypical proliferative serous tumor (APST) or noninvasive low-grade serous carcinoma (LGSC). Implants were classified as noninvasive or invasive. Medical records were collected and reviewed, and follow-up was obtained. Subsequent diagnoses were also confirmed by centralized pathology review. We examined absolute risk and risk factors for recurrent APST and serous carcinoma using Cox regression. The absolute serous carcinoma risk after, respectively, 5 and 20years was 5.0% and 13.9% for noninvasive LGSC, and 0.9% and 3.7% for APST. Serous carcinoma risk was significantly higher following noninvasive LGSC compared with APST among stage I patients/patients without implants (HR=5.3; 95% CI: 1.7-16.3), whereas no significant association with tumor type was found in advanced stage patients/patients with implants. Advanced stage - notably invasive implants - bilaterality, surface involvement, and residual disease increased serous carcinoma risk. However, women with stage I APST also had a higher risk than the general population. This largest population-based cohort of verified SBTs revealed that women with noninvasive LGSC are significantly more likely to develop serous carcinoma than women with APST, which could not entirely be explained by invasive implants. Although invasive implants was a strong risk factor for serous carcinoma, even women with stage I APST were at increased risk compared with the general population. Copyright © 2016 Elsevier Inc.

Immigrant studies offer insights into the relative importance of environment and genes in disease etiology. There is considerable variation in testicular cancer incidence worldwide. We investigated testicular cancer risk in first- and second-generation immigrants to Denmark, a high-incidence country, to evaluate the relative influence of genes and environment and the potential timing of action of environmental factor(s). A cohort of 2.1 million men who were born since 1930 and lived in Denmark between 1968 and 2003 was established based on information in the Danish Civil Registration System, which included their immigration histories. Cancer histories were obtained from the Danish Cancer Registry. Testicular cancer risk was estimated as rate ratios (RRs) with 95% confidence intervals (CIs) based on log-linear Poisson regression. Overall, 4216 testicular cancer cases occurred during 43 million person-years of follow-up in 2.1 million men. These included 166 cases among 344,444 direct immigrants to Denmark and 13 cases among 56,189 men born in Denmark to immigrant parents. These first- and second-generation immigrants had RRs of testicular cancer of 0.37 (95% CI = 0.31 to 0.43) and 0.88 (95% CI = 0.51 to 1.53), respectively, compared with men born in Denmark of parents born in Denmark. The rate in first-generation immigrants was not modified by age at immigration or duration of stay and reflected that in the country of origin. The testicular cancer risk in first-generation immigrants was lower than that in native-born Danes and reflected that in the countries of origin, whereas the risk in second-generation immigrants was similar to that in natives of Denmark. Together these findings argue for a substantial influence of environmental factors limited to the period early in life, most probably to the period in utero.

The prognosis for colorectal cancer (CRC) is less favourable in Denmark than in neighbouring countries. To improve cancer treatment in Denmark, a National Cancer Plan was proposed in 2000. We conducted this population-based study to monitor recent trends in CRC survival and mortality in four Danish counties. We used hospital discharge registry data for the period January 1985-March 2004 in the counties of north Jutland, Ringkjøbing, Viborg and Aarhus. We computed crude survival and used Cox proportional hazards regression analysis to compare mortality over time, adjusted for age and gender. A total of 19,515 CRC patients were identified and linked with the Central Office of Civil Registration to ascertain survival through January 2005. From 1985 to 2004, 1-year and 5-year survival improved both for patients with colon and rectal cancer. From 1995-1999 to 2000-2004, overall 1-year survival of 65% for colon cancer did not improve, and some age groups experienced a decreasing 1-year survival probability. For rectal cancer, overall 1-year survival increased from 71% in 1995-1999 to 74% in 2000-2004. Using 1985-1989 as reference period, 30-day mortality did not decrease after implementation of the National Cancer Plan in 2000, neither for patients with colon nor rectal cancer. However, 1-year mortality for patients with rectal cancer did decline after its implementation. Survival and mortality from colon and rectal cancer improved before the National Cancer Plan was proposed; after its implementation, however, improvement has been observed for rectal cancer only.

Oxytocin for labor augmentation is widely used in obstetric care in Western countries. Two recent, smaller studies found opposing results regarding the association between prenatal exposure to oxytocin for labor augmentation and attention-deficit/hyperactivity disorder (ADHD). In Denmark, oxytocin is the medication used for nearly all medical augmentations of labor, and we examined the association between medical augmentation of labor and ADHD in a large cohort study based on national register data. All singletons born after spontaneous onset of labor in Denmark between 2000 and 2008 (N = 546 146) were included in the study. Data from the Danish Medical Birth Registry on medical augmentation of labor (yes/no) were used to identify exposed children. ADHD was defined based on the diagnostic codes of International Classification of Diseases, 10th Revision, for hyperkinetic disorder and information on dispensed ADHD medication. A multivariate proportional hazards regression model was used to test the association. Among 546 146 deliveries, 26% included medical augmentation of labor, and 0.9% of the children were identified as having ADHD (n = 4617). We found no association between augmentation of labor and ADHD in the offspring (hazard ratio: 1.05 [95% confidence interval: 0.98-1.13]). Our study does not support an association between medical augmentation of labor and ADHD in the child. Copyright © 2015 by the American Academy of Pediatrics.

Seasonality in twin birth rates, Denmark, 1936-84.

A study was made of seasonality in twin birth rate in Denmark between 1977 and 1984. We studied all twin births (N = 45,550) in all deliveries (N = 3,679,932) during that period. Statistical analysis using a simple harmonic sinusoidal model provided no evidence for seasonality. However, sequential polynomial analysis disclosed a significant fit to a fifth order polynomial curve with peaks in twin birth rates in May-June and December, along with troughs in February and September. A falling trend in twinning rate broke off in Denmark around 1970, and from 1970 to 1984 an increasing trend was found. The results are discussed in terms of possible environmental influences on twinning.

In Denmark, maternal mortality has been reported over the last century, both locally through hospital reports and in national registries. The purpose of this study was to analyze data from national medical registries of pregnancy-related deaths in Denmark 1985-1994 and to classify them according to the UK Confidential Enquiry into Maternal Deaths (CEMD). All deaths of women with a registered pregnancy within 12 months prior to the death were identified by comparing the Danish medical registries, death certificates, and relevant codes according to International Classification of Diseases (ICD-10). All cases were classified using the UK CEMD classification. Cases of maternal death were further evaluated by an audit group. 311 cases were classified. 92 deaths (29.6%) occurred 42 days), 1 woman died from a direct obstetric cause, 46 from indirect causes, and 172 from fortuitous causes. Hypertensive disorders of pregnancy were the major cause of direct maternal deaths. The rate of maternal deaths constituted 9.8/100,000 maternities (i.e. the number of women delivering registrable live births at any gestation or stillbirths at 24 weeks of gestation or later). This is the first systematic report on deaths in Denmark based on data from national registries. The maternal mortality rate in Denmark is comparable to the rates in other developed countries. Fortunately, statistics are low, but each case represents potential learning. Obstetric care has changed and classification methods differ between countries. Prospective registration and registry linkage seem to be a way to ensure completion. This retrospective study has provided the background for a prospective study on registration and evaluation of maternal mortality in Denmark.

The aim of the Danish Palliative Care Database (DPD) is to monitor, evaluate, and improve the clinical quality of specialized palliative care (SPC) (ie, the activity of hospital-based palliative care teams/departments and hospices) in Denmark. The study population is all patients in Denmark referred to and/or in contact with SPC after January 1, 2010. The main variables in DPD are data about referral for patients admitted and not admitted to SPC, type of the first SPC contact, clinical and sociodemographic factors, multidisciplinary conference, and the patient-reported European Organisation for Research and Treatment of Cancer Quality of Life Questionaire-Core-15-Palliative Care questionnaire, assessing health-related quality of life. The data support the estimation of currently five quality of care indicators, ie, the proportions of 1) referred and eligible patients who were actually admitted to SPC, 2) patients who waited <10 days before admission to SPC, 3) patients who died from cancer and who obtained contact with SPC, 4) patients who were screened with European Organisation for Research and Treatment of Cancer Quality of Life Questionaire-Core-15-Palliative Care at admission to SPC, and 5) patients who were discussed at a multidisciplinary conference. In 2014, all 43 SPC units in Denmark reported their data to DPD, and all 9,434 cancer patients (100%) referred to SPC were registered in DPD. In total, 41,104 unique cancer patients were registered in DPD during the 5 years 2010-2014. Of those registered, 96% had cancer. DPD is a national clinical quality database for SPC having clinically relevant variables and high data and patient completeness.

Osteonecrosis of the jaw (ONJ) is a severe side effect associated with antiresorptive treatment. Monitoring of ONJ using routine databases in Scandinavian countries is a challenge owing to lack of valid algorithms and to heterogeneous referral practices. The aim of this paper is to describe the process of establishing a Scandinavian ONJ Cohort enrolling all ONJ cases related to antiresorptive treatment arising in Denmark, Norway, and Sweden between 2011 and 2019. The initial purpose of the cohort is to support an ongoing pharmacovigilance study of denosumab and zoledronic acid in Denmark, Norway, and Sweden. The three countries, with their 199 clinics, departments, and units of oral and maxillofacial surgery, both hospital-based and freestanding, differ somewhat in referral practices of the ONJ patients. By directly contacting all providers of care to ONJ patients in the three countries, we established a network for reporting incident cases to each country’s research database directly or through a member of the Scandinavian ONJ task force as a liaison. The task force includes a Scandinavian coordinator and three national coordinators collaborating directly with the clinics. A uniform ONJ registration form has been developed, and the relevant medical community has been informed either directly or through presentations at professional meetings. A website with study information is published in each country, and data entry is ongoing. This large-scale systematic uniform registration of ONJ cases in Denmark, Norway, and Sweden, with an underlying total population of more than 20 million people, merged into the Scandinavian ONJ Cohort, will contribute to better knowledge and understanding of this challenging group of patients, and ultimately, help improve patient care. The Scandinavian ONJ Cohort as a whole and its component national ONJ research databases may offer the potential for large-scale multinational intervention and safety studies in the future.

Delivery of screening mammography differs substantially between the United States (US) and Denmark. We evaluate whether there are differences in screening sensitivity and specificity. We included screens from women screened at age 50-69 years during 1996-2008/2009 in the US Breast Cancer Surveillance Consortium (BCSC) (n=2,872,791), and from two population-based mammography screening programs in Denmark (Copenhagen, n=148,156 and Funen, n=275,553). Women were followed for one year. For initial screens, recall rate was significantly higher in BCSC (17.6%) than in Copenhagen (4.3%) and Funen (3.1%). Sensitivity was fairly similar in BCSC (91.8%) and Copenhagen (90.5%) and Funen (92.5%). At subsequent screens, recall rates were 8.8%, 1.8% and 1.4% in BCSC, Copenhagen and Funen, respectively. The BCSC sensitivity (82.3%) was lower compared to Copenhagen (88.9%) and Funen (86.9%), but when stratified by time since last screen, the sensitivity was similar. For both initial and subsequent screening, the specificity of screening in BCSC (83.2 and 91.6%) was significantly lower than in Copenhagen (96.6 and 98.8%) and Funen. (97.9 and 99.2%). Taking time since last screen into account, American and Danish women had the same probability of having their asymptomatic cancers detected at screening. However, the majority of women free of asymptomatic cancers experienced more harms in terms of false-positive findings in the US than in Denmark. PMID:25944711

In this paper, we examine income- and education-related inequality in small-for-gestational age (SGA) and preterm birth in Denmark and Finland from 1987 to 2003 using concentration indexes (CIXs). From the national medical birth registries we gathered information on all births from 1987 to 2003. Information on highest completed maternal education and household income in the year preceding birth of the offspring was obtained for 1,012,400 births in Denmark and 499,390 in Finland. We then calculated CIXs for income- and education-related inequality in SGA and preterm birth. The mean household income-related inequality in SGA was -0.04 (95% confidence interval: -0.05, -0.04) in Denmark and -0.03 (-0.04, -0.02) in Finland. The maternal education-related inequality in SGA was -0.08 (-0.10, -0.06) in Denmark and -0.07 (-0.08, -0.06) in Finland. The income-related inequality in preterm birth was -0.03 (-0.03, -0.02) in Denmark and -0.03 (-0.04, -0.02) in Finland. The education-related inequality in preterm birth was -0.05 (-0.07, -0.04) in Denmark and -0.04 (-0.05, -0.03) in Finland. In Denmark, the income-related and education-related inequity in SGA increased over time. In Finland, the income-related inequality in SGA birth increased slightly, while education-related inequalities remained stable. Inequalities in preterm birth decreased over time in both countries. Denmark and Finland are examples of nations with free prenatal care and publicly financed obstetric care of high quality. During the period of study there were macroeconomic shocks affecting both countries. However, only small income- and education-related inequalities in SGA and preterm births during the period were observed.

The presence of dysplastic nevus remnants in malignant melanomas. A population-based study of 551 malignant melanomas.

We examined 512 malignant melanomas, representing all newly diagnosed cutaneous malignant melanomas, excluding lentigo maligna melanomas, from the period October 1, 1982 to March 31, 1985 occurring in the region of eastern Denmark in patients aged 20-79 years for the presence of dysplastic nevus remnants. Criteria for the diagnosis of a dysplastic nevus remnant include all the following changes (a) lentiginous or epithelioid melanocyte hyperplasia, (b) cytologic melanocyte atypia, (c) eosinophilic fibroplasia, (d) lamellar fibroplasia, and (e) lymphocytic infiltration in the dermis. Dysplastic nevus remnants were found in association with 34 (7%) of the evaluable 512 malignant melanomas. Fourteen (41%) of the remnants were of compound nevus type. In nine (27%) of the remnants, atypia was pronounced. Most (62%) dysplastic nevus remnants were contiguous to thin superficial spreading melanomas. We conclude from this population-based study that about 7% of malignant melanomas arise in prior dysplastic nevi.

Scandinavian epidemiological research in gastroenterology and hepatology.

PubMed

Björnsson, Einar S; Ekbom, Anders

2015-06-01

In the last decades, a large number of epidemiological studies in gastroenterology and hepatology have originated from the Scandinavian countries. With the help of large health databases, with good validity and other registries related to patient outcomes, researchers from the Scandinavian countries have been able to make some very important contributions to the field. These countries, Sweden, Norway, Finland, Denmark and Iceland, have all universal access to health care and have shown to be ideal for epidemiological research. Population-based studies have been frequent and follow-up studies have been able to describe the temporal trends and changes in phenotypes. Our ability in Scandinavia to follow up defined groups of patients over time has been crucial to learn the natural history of many gastrointestinal and liver diseases and often in a population-based setting. Patient-related outcomes measures will probably gain increasing importance in the future, but Scandinavian gastroenterologists and surgeons are likely to have a better infrastructure for such endeavors compared to most other populations. Thus, there is a bright future for international competitive research within the field of gastrointestinal and liver diseases in Scandinavia.

Contact dermatitis is a frequent occupational and non-occupational skin disease. To investigate the effects of contact dermatitis on labour market affiliation and societal costs in terms of healthcare costs and production loss. A total of 21 441 patients patch tested either in hospital departments or at dermatological clinics in the period 2004-2009 were included in the study. The analyses were stratified by children (age 0-15 years), occupational contact dermatitis (age 16-65 years), and non-occupational dermatitis (age ≥ 16 years). Controls were selected from a 30% random sample of the population. Individual encrypted data were retrieved on healthcare utilization, socio-demographics, education, labour market affiliation and transfer payments from public registers in Denmark for cases and controls. Attributable healthcare costs for 4 years prior to patch testing (1 year for children) and the year after patch testing were €959 for children, €724 for occupational contact dermatitis, and €1794 for non-occupational dermatitis. Productivity costs for the same period were €10 722 for occupational contact dermatitis and €3074 for non-occupational contact dermatitis. The main findings of this study were that there were statistically significant attributable healthcare costs for both children and adults, and statistically significant productivity loss for adults. © 2014 John Wiley & Sons A/S.

Flexicurity, or the integration of labor market flexibility with social security and active labor market policies, has figured prominently in economic and social policy discussions in Europe since the mid-1990s. Such policies are designed to transcend traditional labor-capital conflicts and to form a mutually supportive nexus of flexibility and security within a climate of intensified competition and rapid technological change. International bodies have marketed flexicurity as an innovative win-win strategy for employers and workers alike, commonly citing Denmark and The Netherlands as exemplars of best practice. In this article, we apply a social determinants of health framework to conduct a scoping review of the academic and gray literature to: (a) better understand the empirical associations between flexicurity practices and population health in Denmark and (b) assess the relevance and feasibility of implementing such policies to improve health and reduce health inequalities in Ontario, Canada. Based on 39 studies meeting our full inclusion criteria, preliminary findings suggest that flexicurity is limited as a potential health promotion strategy in Ontario, offers more risks to workers' health than benefits, and requires the strengthening of other social protections before it could be realistically implemented within a Canadian context.

Azole-resistant Aspergillus fumigatus harboring the TR34/L98H or TR46/Y121F/T289A alterations is increasingly found in Europe and Asia. Here, we present the first clinical cases of TR46/Y121/T289A and three cases of TR34/L98H outside the cystic fibrosis (CF) population in Denmark and the results of environmental surveys. Four patients (2012 to 2014) with 11 A. fumigatus and 4 Rhizomucor pusillus isolates and 239 soil samples (spring 2010 and autumn 2013, respectively) with a total of 113 A. fumigatus isolates were examined. Aspergillus isolates were screened for azole resistance using azole-containing agar. Confirmatory susceptibility testing was done using the EUCAST microbroth dilution EDEF 9.1 reference method. For relevant A. fumigatus isolates, CYP51A sequencing and microsatellite genotyping were performed. Three patients harbored TR34/L98H isolates. Two were azole naive at the time of acquisition and two were coinfected with wild-type A. fumigatus or R. pusillus isolates, complicating and delaying diagnosis. The TR46/Y121F/T289A strain was isolated in 2014 from a lung transplant patient. Genotyping indicated that susceptible and resistant Aspergillus isolates were unrelated and that no transmission between patients occurred. Azole resistance was not detected in any of the 113 soil isolates. TR34/L98H and TR46/Y121F/T289A alterations appear to be emerging in the clinical setting in Denmark and now involve azole-naive patients. Two recent soil-sampling surveys in Denmark were unable to indicate any increased prevalence of azole-resistant A. fumigatus in the environment. These findings further support the demand for real-time susceptibility testing of all clinically relevant isolates and for studies investigating the seasonal variation and ecological niches for azole-resistant environmental A. fumigatus.

Background Immigrant populations in Western European countries have grown in their size and diversity, but little is known about risks of self-directed and externalised violence among second generation immigrants. Aims To compare risks for attempted suicides and violent offending among second generation immigrants to Denmark according to parental region of origin versus the native Danish population. Methods Data from interlinked national Danish registers were used (N=1,973,614). Parental origin outside Denmark was categorised thus: Asia, Africa, Middle East, Greenland, other Scandinavian countries, elsewhere in Europe, and all other regions. We estimated gender-specific cumulative incidence and incidence rate ratios (IRRs) versus native Danes. Results In virtually all subgroups of second generation immigrants, risk was elevated for the two adverse outcomes in both genders. Females generally had greater elevations in attempted suicide risk, and males had greater elevations in violent offending risk. For attempted suicide, especially large IRRs were observed for males and females whose parents emigrated from Greenland; for violent offending, risks were particularly raised for males and females of Middle Eastern, Greenlandic and African origin. Adjustment for socioeconomic status partially explained these associations. Conclusions Western European nations should develop preventive programmes tailored toward specific second generation immigrant populations, with integrated approaches jointly tackling suicidality and violence.

Sickness absence patterns and trends in the health care sector: 5-year monitoring of female municipal employees in the health and care sectors in Norway and Denmark

PubMed Central

2014-01-01

Background Sickness absence is a growing public health problem in Norway and Denmark, with the highest absence rates being registered in Norway. We compared time trends in sickness absence patterns of municipal employees in the health and care sectors in Norway and Denmark. Methods Data from 2004 to 2008 were extracted from the personnel registers of the municipalities of Kristiansand, Norway, and Aarhus, Denmark, for 3,181 and 8,545 female employees, respectively. Age-specific comparative statistics on sickness absence rates (number of calendar days of sickness absence/possible working days) and number of sick leave episodes were calculated for each year of the study period. Results There was an overall increasing trend in sickness absence rates in Denmark (P = 0.002), where rates were highest in the 20–29- (P = 0.01) and 50–59-year-old age groups (P = 0.03). Sickness absence rates in Norway were stable, except for an increase in the 20–29-year-old age group (P = 0.004). In both Norway and Denmark, the mean number of sick leave episodes increased (P <0.0001 and P <0.0001, respectively) in all age groups except for the 30–39- and 60–67-year-old age groups. The proportion of employees without sickness absence was higher in Norway than in Denmark. Both short-term and long-term absence increased in Denmark (P = 0.003 and P <0.0001, respectively), while in Norway, only short-term absence increased (P = 0.09). Conclusions We found an overall increase in sickness absence rates in Denmark, while the largest overall increase in sick leave episodes was found in Norway. In both countries, the largest increases were observed among young employees. The results indicate that the two countries are converging in regard to sickness absence measured as rates and episodes.

The association between relationship markers of sexual orientation and suicide: Denmark, 1990-2001.

Mathy, Robin M; Cochran, Susan D; Olsen, Jorn; Mays, Vickie M

2011-02-01

Minority sexual orientation has been repeatedly linked to elevated rates of suicide attempts. Whether this translates into greater risk for suicide mortality is unclear. We investigated sexual orientation-related differences in suicide mortality in Denmark during the initial 12-year period following legalization of same-sex registered domestic partnerships (RDPs). Using data from death certificates issued between 1990 and 2001 and population estimates from the Danish census, we estimated suicide mortality risk among individuals classified into one of three marital/cohabitation statuses: current/formerly in same-sex RDPs; current/formerly heterosexually married; or never married/registered. Risk for suicide mortality was associated with this proxy indicator of sexual orientation, but only significantly among men. The estimated age-adjusted suicide mortality risk for RDP men was nearly eight times greater than for men with positive histories of heterosexual marriage and nearly twice as high for men who had never married. Suicide risk appears greatly elevated for men in same-sex partnerships in Denmark. To what extent this is true for similar gay and bisexual men who are not in such relationships is unknown, but these findings call for targeted suicide prevention programs aimed at reducing suicide risk among gay and bisexual men.

Experience with monocomponent acellular pertussis combination vaccines for infants, children, adolescents and adults--a review of safety, immunogenicity, efficacy and effectiveness studies and 15 years of field experience.

Combination vaccines containing a monocomponent acellular pertussis (aP) vaccine, manufactured at Statens Serum Institut (SSI), Denmark, have successfully controlled Bordetella pertussis infections in Denmark since 1997. The efficacy of this aP vaccine was 71% in a double-blind, randomised and controlled clinical trial. Its safety and immunogenicity have been demonstrated in infants, children, adolescents and adults. In approximately 500,000 children it was effective against pertussis requiring hospitalisation (VE: 93% after 3 doses) and against pertussis not requiring hospitalisation (VE: 78% after 3 doses). IgG antibodies against pertussis toxin (IgG anti-PT) response rates after booster vaccination of adults with tetanus, diphtheria and aP combination vaccine (TdaP) were considerably higher for this monocomponent aP vaccine containing 20μg pertussis toxoid, inactivated by hydrogen peroxide (92.0%), than for two multicomponent aP vaccines inactivated by formaldehyde and/or glutaraldehyde: 3-component aP with 8μg pertussis toxoid (77.2%) and 5-component aP with 2.5μg pertussis toxoid (47.1%), without compromising the safety profile. In Denmark where this monocomponent aP vaccine has been the only pertussis vaccine in use for 15 years, there has been no pertussis epidemic since 2002 (population incidence 36 per 100,000), in contrast to neighbouring countries, where epidemics have occurred. This monocomponent aP vaccine can be used in combination vaccines for primary and booster vaccination against pertussis in all age groups and is an important tool for successful pertussis control.

The impact of job satisfaction on the risk of disability pension. A 15-year prospective study.

PubMed

Labriola, Merete; Feveile, Helene; Christensen, Karl Bang; Bültmann, Ute; Lund, Thomas

2009-09-01

To identify the impact of job satisfaction on the risk of disability pension. A total of 8,338 employees were sampled from the total working population in Denmark. They were interviewed regarding age, gender, job satisfaction and health behaviour. Interview data were merged with national register data on granted disability pension for up to 15 years after baseline data collection. The study found a statistically significant association between low job satisfaction and disability pension for women when adjusted for age, smoking status and BMI. Based on the results, investing in giving workers a satisfying work environment could be a low-cost way of improving employee health and prolonging labour market participation.

Analyzing the relationship between car generation and severity of motor-vehicle crashes in Denmark.

2013-05-01

While the number of fatalities on Danish roads has decreased in the last 40 years, research has not investigated the contribution of legislation changes, enforcement measures, technological enhancements, infrastructural improvements and human factors to this reduction. In the context of a Danish car market with remarkably high registration tax that causes potential buyers to hold longer onto old cars, the relationship between technological enhancements of vehicles and severity of crashes requires particular attention. The current study investigated the relationship between car generation (i.e., car's first registration year) and injury severity sustained by car drivers involved in accidents in Denmark between 2004 and 2010. A generalized ordered logit model was estimated while controlling for several characteristics of the crash, the vehicle and the persons involved, and a sensitivity analysis was performed to assess the effect of car generation on drivers' injury severity. Results illustrate that newer car generations are associated to significantly lower probability of injury and fatality, and that replacing older cars with newer ones introduces significant and not to be overlooked benefits for both population and society.

We aimed to investigate the incidence and mortality of herpes simplex encephalitis (HSE) in a nationwide cohort. From the Danish National Patient Registry, we identified all adults hospitalised with a first-time diagnosis of HSE in Denmark during 2004-2014. The HSE diagnoses were verified using medical records and microbiological data. Patients were followed for mortality through the Danish Civil Registry System. We estimated age-standardised incidence rates of HSE and 30-day, 60-day, and 1-year cumulative mortality. Furthermore, we assessed whether calendar year, age, gender, level of comorbidity, virus type, and department type was associated with HSE mortality. We identified a total of 230 cases of HSE. Median age was 60.7 years (interquartile range: 49.3-71.6). The overall incidence rate was 4.64 cases per million population per year (95% confidence interval: 4.06-5.28). The cumulative mortality within 30 days, 60 days, and 1 year of the HSE admission was 8.3%, 11.3%, and 18.6%, respectively. Advanced age and presence of comorbidity were associated with increased 60-day and 1-year mortality. This nationwide study of verified HSE found a higher incidence than reported in previous nationwide studies. Presence of comorbidity was identified as a novel adverse prognostic factor. Mortality rates following HSE remain high. Copyright © 2016 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

Use of history science methods in exposure assessment for occupational health studies

Aims: To show the power of history science methods for exposure assessment in occupational health studies, using the dry cleaning industry in Denmark around 1970 as the example. Methods: Exposure data and other information on exposure status were searched for in unconventional data sources such as the Danish National Archives, the Danish Royal Library, archives of Statistics Denmark, the National Institute of Occupational Health, Denmark, and the Danish Labor Inspection Agency. Individual census forms were retrieved from the Danish National Archives. Results: It was estimated that in total 3267 persons worked in the dry cleaning industry in Denmark in 1970. They typically worked in small shops with an average size of 3.5 persons. Of these, 2645 persons were considered exposed to solvents as they were dry cleaners or worked very close to the dry cleaning process, while 622 persons were office workers, drivers, etc in shops with 10 or more persons. It was estimated that tetrachloroethylene constituted 85% of the dry cleaning solvent used, and that a shop would normally have two machines using 4.6 tons of tetrachloroethylene annually. Conclusion: The history science methods, including retrieval of material from the Danish National Archives and a thorough search in the Royal Library for publications on dry cleaning, turned out to be a very fruitful approach for collection of exposure data on dry cleaning work in Denmark. The history science methods proved to be a useful supplement to the exposure assessment methods normally applied in epidemiological studies. PMID:15961618

Vitamin D intakes are lower than dietary recommendations in most populations, and thus, a low vitamin D status is widespread, especially during winter. We investigated the effects of increasing vitamin D intake to the recommended amount by fortification of milk and bread on serum 25-hydroxyvitamin D [25(OH)D] concentrations in families during winter in Denmark. The study was a randomized controlled trial in 782 children and adults (4-60 y old) recruited as 201 families. Families were randomly assigned to vitamin D-fortified or nonfortified milk and bread for 6 mo starting in September. The milk and bread replaced the participants' usual consumptions of products. Median (IQR) vitamin D intakes (habitual diet plus fortified products) were 9.4 mg/d (6.5, 12.3 mg/d) and 2.2 mg/d (1.5, 3.0 mg/d) in fortification and control groups, respectively. Geometric mean (IQR) serum 25(OH)D concentrations decreased from 73.1 nmol/L (61.9, 88.5 nmol/L) to 67.6 nmol/L (56.2, 79.4 nmol/L) in the fortification group and from 71.1 nmol/L (61.2, 85.9 nmol/L) to 41.7 nmol/L (29.5, 58.9 nmol/L) in the control group (both P , 0.001). The final 25(OH)D concentration was significantly higher in the fortification group than in the control group (P , 0.001). By the end of the study, ,1% of subjects in the fortification group and 25% of subjects in the control group had 25(OH)D concentrations ,30 nmol/L and 16% and 65% of subjects, respectively, had 25(OH)D concentrations ,50 nmol/L. Vitamin D fortification of milk and bread reduces the decrease in serum 25(OH)D concentrations during winter and ensures 25(OH)D concentrations .50 nmol/L in children and adults in Denmark.

To identify dietary patterns with whole grains as a main focus to see if there is a similar whole grain pattern in the three Scandinavian countries; Denmark, Sweden and Norway. Another objective is to see if items suggested for a Nordic Food Index will form a typical Nordic pattern when using factor analysis. The HELGA study population is based on samples of existing cohorts: the Norwegian Women and Cancer Study, the Swedish Västerbotten cohort and the Danish Diet, Cancer and Health study. The HELGA study aims to generate knowledge about the health effects of whole grain foods. The study included a total of 119 913 participants. The associations among food variables from FFQ were investigated by principal component analysis. Only food groups common for all three cohorts were included. High factor loading of a food item shows high correlation of the item to the specific diet pattern. The main whole grain for Denmark and Sweden was rye, while Norway had highest consumption of wheat. Three similar patterns were found: a cereal pattern, a meat pattern and a bread pattern. However, even if the patterns look similar, the food items belonging to the patterns differ between countries. High loadings on breakfast cereals and whole grain oat were common in the cereal patterns for all three countries. Thus, the cereal pattern may be considered a common Scandinavian whole grain pattern. Food items belonging to a Nordic Food Index were distributed between different patterns.

Suicide by carbon monoxide from car exhaust-gas in Denmark 1995-1999.

PubMed

Thomsen, Asser H; Gregersen, Markil

2006-08-10

In the period 1995-1999 there were 388 car exhaust-gas suicides in Denmark. Of these 343 (88.4%) were men and 45 (11.6%) were women, the average age being 47 years. The car exhaust-gas suicides made up 9.3% of all suicides in Denmark in the period. The corresponding rate was 11.7% for men and 3.7% for women. In rural areas a larger part of all suicides were committed with car exhaust-gas compared to the more densely populated areas. Mental disease was diagnosed in 124 (32.0%) cases. A suicide note was found in 165 (42.5%) cases. A hose was fitted to the exhaust pipe in 334 (86.1%) cases. Of these the 234 (60.3%) occurred outside, typically in a forest area, while 76 (19.6%) occurred in a closed garage. All the 54 (13.9%) cases with no hose fitted to the exhaust pipe occurred in a garage. Seven (1.8%) victims were found in a burning or burnt-out car, where the following investigation revealed that it was actually a car exhaust-gas suicide. Carboxyhemoglobin was measured in 26 (6.7%) victims. In two of these victims no carboxyhemoglobin was found, as they had survived for some time after the poisoning. The average saturation of the remaining victims was 67%, the lowest saturation being 20% and the highest being 84%. In the period 1969-1987 the number of car exhaust-gas suicides in Denmark increased from 50 to approximately 190 per year and the rate of car exhaust-gas suicides compared to all suicides increased from approximately 5% to approximately 13%. In 1987-1999 these figures decreased from approximately 190 to 63 per year and from 13% to approximately 8%. During these 30 years the number of passenger cars in Denmark doubled, which explains the increase in car exhaust-gas suicides during 1969-1987. A possible explanation for the decrease in 1987-1999 is the introduction of the catalytic converter, which was made mandatory in 1990. We anticipate that car exhaust-gas suicides will continue to decrease in numbers, as more cars are equipped with catalytic converters.

Breastfeeding practices in relation to country of origin among women living in Denmark: a population-based study.

The objective of this study was to describe breastfeeding practices and to compare the risk of suboptimal breastfeeding of women living in Denmark according to country of origin, and further to examine how socio-economic position and duration of stay in the country affected this risk. Information on breastfeeding of 42,420 infants born 2002-2009 and living in eighteen selected Danish municipalities was collected from the Danish Health Visitor's Child Health Database. The data was linked with data on maternal socio-demographic information from Danish population-covering registries. Suboptimal breastfeeding was defined as <4 months of full breastfeeding as described by the Danish Health and Medicines Authority. We used logistic regression to model the crude associations between suboptimal breastfeeding and country of origin, and taking maternal age and parity, and a variety of parental socio-economic measures into account. Suboptimal breastfeeding was more frequent among non-Western migrant women than among women of Danish origin. Women who were descendants of Turkish and Pakistani immigrants had a higher risk of suboptimal breastfeeding as compared to the group of women who had migrated from the same countries, suggesting that acculturation did not favor breastfeeding. For all but the group of women who had migrated from Pakistan, adjustment for socio-demographic indicators (age, parity, education, attachment to labour market, and income) eliminated the increased risk of suboptimal breastfeeding. There was no evidence for differences in the breastfeeding support provided at hospital level according to migrant status. Suboptimal breastfeeding was more frequent among women who were non-Nordic migrants and descendants of migrants than among women with Danish origin.

Recent hip fracture trends in Sweden and Denmark with age-period-cohort effects.

This study used nationwide hip fracture data from Denmark and Sweden during 1987-2010 to examine effects of (birth) cohort and period. We found that time trends, cohort, and period effects were different in the two countries. Results also indicated that hip fracture rates may increase in the not so far future. The reasons for the downturn in hip fracture rates remain largely unclear but circumstances earlier in life seem important. We ascertained hip fractures in the populations ≥50 years in Denmark and Sweden in national discharge registers. Country- and sex-specific age-period-cohort (APC) effects during 1987-2010 were evaluated by log-likelihood estimates in Poisson regression models presented as incidence rate ratios (IRR). There were 399,596 hip fractures in SE and 248,773 in DK. Age-standardized hip fracture rate was stable in SE men but decreased in SE women and in DK. Combined period + cohort effects were generally stronger in SE than DK and in women than men. IRR per period ranged from 1.05 to 1.30 in SE and 0.95 to 1.21 in DK. IRR per birth cohort ranged from 1.07 to 3.13 in SE and 0.77 to 1.67 in DK. Relative period effects decreased with successive period in SE and described a convex curve in DK. Relative cohort effects increased with successive birth cohort in both countries but with lower risks for DK women and men and SE women born around the 1930s (age 75-86 years today and responsible for most hip fractures) partly explaining the recent downturn. Men and women born thereafter however seem to have a higher hip fracture risk, and we expect a reversal of the present decline in rates, with increasing hip fracture rates in both Denmark and Sweden during the upcoming decade. Time trends, cohort, and period effects were different in SE and DK. This may reflect differences in general health as evident in known differences in life expectancy, healthcare organization, and prevention such as use of anti-osteoporosis drugs. Analyses indicate that hip fracture rates may increase in the not so far future.

Background Very little is currently known about air pollutants’ adverse effects on neurodegenerative diseases even though recent studies have linked particulate exposures to brain pathologies associated with Parkinson’s and Alzheimer’s disease. Objective In the present study, we investigated long-term exposure to traffic-related air pollution and Parkinson’s disease. Methods In a case–control study of 1,696 Parkinson’s disease (PD) patients identified from Danish hospital registries and diagnosed 1996–2009 and 1,800 population controls matched by sex and year of birth, we assessed long-term traffic-related air pollutant exposures (represented by nitrogen dioxide; NO2) from a dispersion model, using residential addresses from 1971 to the date of diagnosis or first cardinal symptom for cases and the corresponding index date for their matched controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated with logistic regression, adjusting for matching factors and potential confounders. Results We found ambient air pollution from traffic sources to be associated with risk of PD, with a 9% higher risk (95% CI: 3, 16.0%) per interquartile range increase (2.97 μg/m3) in modeled NO2. For participants living for ≥ 20 years in the capital city, ORs were larger (OR = 1.21; 95% CI: 1.11, 1.31) than in provincial towns (OR = 1.10; 95% CI: 0.97, 1.26), whereas there was no association among rural residents. Conclusions Our findings raise concerns about potential effects of air pollution from traffic and other sources on the risk of PD, particularly in populations with high or increasing exposures.

Malnutrition is common in dialysis patients and is associated with adverse clinical outcomes. Despite an increased focus on improved nutrition in dialysis patients, it is claimed that the prevalence of malnutrition in this group of patients has not changed during the last decades. Direct historical comparisons of the nutritional status of dialysis patients have never been published. To directly compare the nutritional status of past and current dialysis patients, we implemented the methodology of a study from 1986 on a population of dialysis patients in 2014. Historical study comparing results of two cross-sectional studies performed in 1986 and 2014. We compared the nutritional status of hemodialysis (HD) and peritoneal dialysis (PD) patients attending the dialysis center at Roskilde Hospital, Denmark, in February to June 2014, with that of HD and PD patients treated at the dialysis center at Fredericia Hospital, Denmark, in April 1986. Maintenance PD and HD patients (n = 64 in 2014 and n = 48 in 1986). We performed anthropometry (body weight, triceps skinfold, and midarm muscle circumferences [MAMCs]) and determined plasma transferrin. Relative body weight, triceps skinfold, MAMC, body mass index, and prevalence of protein-caloric malnutrition as defined in the original study from 1986. Average relative body weight, triceps skinfold, MAMC, and body mass index were significantly higher in 2014 compared with 1986. The prevalence of protein-caloric malnutrition was significantly lower in 2014 (18%) compared with 1986 (52%). The nutritional status of maintenance dialysis patients has improved during the last 3 decades. The reason for this improvement could not be identified in the present study, but the most likely contributors are the higher prevalence of obesity in the general population, less predialytic malnutrition, and an improved focus on nutrition in maintenance dialysis patients.

Achieving home death is often seen as an important endpoint in palliative care, but no studies of the preferred place-of-death have yet been conducted in Scandinavia. Furthermore, we do not know if professionals' report on deceased patients' preference of place-of-death is a valid information. The aim of this study was to describe where terminally ill Danish cancer patients prefer to die and to determine if their preference changed during the palliative period, as reported retrospectively by bereaved relatives, general practitioners (GPs) and community nurses (CNs) and to assess the agreement of their accounts. The study was a population-based, cross-sectional combined register and questionnaire study in Aarhus County, Denmark. The population comprised 599 deceased adult cancer patients who had died from 1 March to 30 November 2006 and were identified through merging of health registers. Relatives returned 198 questionnaires about patients' preferred place-of-death, GPs 333 and CNs 201. The study showed that most terminally ill cancer patients preferred home death (up to 80.7%). The reported preference for home death weakened as death approached (down to 64.4%). A better congruence was seen between relatives' and GPs' accounts of preference for place of death at the end of the palliative period (κ 0.71) than between relatives' and CNs' accounts (κ 0.37). In conclusion, bereaved relatives (and GPs and CNs) report retrospectively that most terminally ill cancer patients wish to die at home. The preference weakened significantly as death approached. The agreement between relatives' and GPs' accounts on patients' preferences at the end of the palliative period was 'substantial', whereas the agreement between relatives' and CNs' accounts at the same time was significantly less outspoken. This indicates that CNs may be facing a problem in assessing their patients' wishes retrospectively. © 2011 The Authors.

There may be various reasons for differences in suicide rates between countries and over time within a country. One reason can be different registration practices. The purpose of this study was to describe and compare the present procedures for mortality and suicide registration in the three Scandinavian countries and to illustrate potential sources of error in the registration of suicide. Information about registration practices and classification procedures was obtained from the cause of death registers in Norway, Sweden, and Denmark. In addition, we received information from experts in the field in each country. Sweden uses event of undetermined intent more frequently than Denmark does, and Denmark more frequently than Norway. There seems to be somewhat more uncertainty among deaths classified as ill-defined and unknown cause of mortality in Norway, compared with the other two countries. Sweden performs more forensic autopsies than Norway, and Norway more than Denmark. In Denmark, in cases of a suspected unnatural manner of death, a thorough external examination of the deceased is performed. Differences in the classification of causes of death and in postmortem examinations exist in Scandinavian countries. These differences might influence the suicide statistics in Scandinavia.

Doubling Syndemics

PubMed Central

2017-01-01

Abstract This study investigates health concerns and access to health services for Roma from Romania who live in homelessness in Copenhagen, Denmark. They collect refundable bottles and call themselves “badocari,” which in Romanian refers to “people who work with bottles.” Homeless Roma in Denmark have not previously been studied through ethnographic research. The study stresses the importance of a syndemic approach towards understanding badocari health concerns. Syndemics is understood as co-occurring diseases, which unfold within contexts of social injustice. The case of the badocari is argued to be a case of “doubling syndemics” since the co-occurring diseases are further multiplied and enhanced by an ongoing mobility between dual contexts of precarious livelihoods in Romania and Denmark, respectively. The study complements the approach to syndemics with a perspective on human rights. It sheds light on the limited possibilities that exist for addressing health concerns of the badocari, both in Romania and in Denmark, and argues that the universal human right to health is not realized in the everyday lives of destitute EU migrants such as the badocari. Rather, they experience lack of access to adequate medical treatment and follow-up care, both as citizens of a member state and as co-citizens of the European Union. PMID:29302164

Adaptive harvest management for the Svalbard population of pink-footed geese: 2015 progress summary

Johnson, Fred A.; Madsen, Jesper

2015-01-01

This document describes progress to date on the development of an adaptive harvest management strategy for maintaining the Svalbard population of pink‐footed geese (Anser brachyrhynchus) near their agreed target level (60,000) by providing for sustainable harvests in Norway and Denmark. This report provides an assessment of the most recent monitoring information (1991-2014) and its implications for the harvest management strategy, and it is an update of an initial assessment for 2013-2015 (see http://pinkfootedgoose.aewa.info/). By combining varying hypotheses about survival and reproduction, a suite of nine models have been developed that represent a wide range of possibilities concerning the extent to which demographic rates are density dependent or independent. Current updated model weights suggest little evidence for density-dependent survival and reproduction, suggesting that the population may have recently experienced a release from density-dependent mechanisms, corresponding to the period of most rapid growth in population size. The optimal harvest strategy for the 2013–2015 hunting seasons prescribed a harvest quota of 15,000 per year. The harvest in the 2014 hunting season was 14,991, compared to 11,081 in 2013, mostly due to an increase in harvest in Denmark during January 2015. The percentage of young in the fall of 2014 was 10.3%, which is lower than average. The observed population size of 59,000 in May 2015 was much lower than expected. For the 2015 hunting season, observed population size and temperature days suggest that an emergency closure should be considered. In the event a harvest of 15,000 is maintained, predicted population size in May 2016 is 51,700 (95% CL: 41,600-64,300), based on observed TempDays = 9 in May 2015 and the most recent model weights. On the other hand, if the season were closed this year, we would expect a population size of 66,700 (95% CL: 53,600-82,900) in May 2016. A total harvest of 6,700 would be expected to result in a 2016 population size at goal (i.e., 60,000).

The objective of this review is to describe the possibilities to assess drugs used in pregnancy by means of the Nordic health registers. The Nordic countries comprise five countries: Denmark, Finland, Iceland, Norway and Sweden and have a total population of 25 million. All five countries have in their national health registers for many years recorded information concerning all births, cancer diagnoses, hospital contacts, causes of death and dispensed drugs. The registers can be used for studying drugs dispensed during pregnancy and though most previous studies focused on risks of congenital abnormalities, other health consequences of maternal medication can also be assessed. © 2014 Société Française de Pharmacologie et de Thérapeutique.

Thirty-five percent of Danish women experience sexual or physical violence in their lifetime. However, health care professionals are not in the practice of asking about intimate partner violence (IPV) in Denmark. It is currently unknown what hinders general practitioners from asking about partner violence and how Danish women would perceive such an inquiry. This aspect has not previously been explored in Denmark. An exploratory study was conducted to examine what hinders general practitioners (GPs) from asking and what Danish women's views and attitudes are regarding being asked about IPV. Data were collected through individual and group interviews with a sample of three GPs and a diverse sample of 13 women, including both survivors of partner violence and those without any history of partner violence. An interpretative analysis was performed with the data. This study provides important knowledge regarding the barriers and attitudes towards inquiry about IPV in primary care in Denmark. Results indicate that Denmark is facing the same challenges when responding to survivors of IPV as other similar countries, including Sweden, Norway, the UK, USA, and Australia. Danish women want general practitioners to ask about violence in a respectful and non-judgemental manner. However, general practitioners are resistant towards such an inquiry and would benefit from training regarding how to respond to women who have been exposed to IPV. It is acceptable to inquire about IPV with women in Denmark in a non-judgemental and respectful way. Informing about IPV prevalence is important prior to the inquiry. However, general practitioners require more awareness and training before a favourable environment for this change in procedure can be created. Further large-scale research is needed to support the evidence generated by this small study.

Use of complementary and alternative medicine at Norwegian and Danish hospitals

PubMed Central

2011-01-01

Background Several studies have found that a high proportion of the population in western countries use complementary and alternative medicine (CAM). However, little is known about whether CAM is offered in hospitals. The aim of this study was to describe to what extent CAM is offered in Norwegian and Danish hospitals and investigate possible changes in Norway since 2001. Methods A one-page questionnaire was sent to all included hospitals in both countries. The questionnaire was sent to the person responsible for the clinical activity, typically the medical director. 99 hospitals in the authority (85%) in Norway and 126 in Denmark (97%) responded. Given contact persons were interviewed. Results CAM is presently offered in about 50% of Norwegian hospitals and one-third of Danish hospitals. In Norway CAM was offered in 50 hospitals, 40 of which involved acupuncture. 19 hospitals gave other alternative therapies like biofeedback, hypnosis, cupping, ear-acupuncture, herbal medicine, art therapy, homeopathy, reflexology, thought field therapy, gestalt therapy, aromatherapy, tai chi, acupressure, yoga, pilates and other. 9 hospitals offered more than one therapy form. In Denmark 38 hospitals offered acupuncture and one Eye Movement Desensitization and Reprocessing Light Therapy. The most commonly reported reason for offering CAM was scientific evidence in Denmark. In Norway it was the interest of a hospital employee, except for acupuncture where the introduction is more often initiated by the leadership and is more based on scientific evidence of effect. All persons (except one) responsible for the alternative treatment had a medical or allied health professional background and their education/training in CAM treatment varied substantially. Conclusions The extent of CAM being offered has increased substantially in Norway during the first decade of the 21st century. This might indicate a shift in attitude regarding CAM within the conventional health care system. PMID:21244655

To estimate and test associations between substance use disorders (SUDs) and both completed suicides and suicide attempts in a population with severe mental illness. Register-based cohort study with adjusted Cox regression of substance use disorders as time-varying covariates. Denmark. People born in Denmark since 1955 with a diagnosis of schizophrenia (n = 35 625), bipolar disorder (n = 9279), depression (n = 72 530) or personality disorder (n = 63 958). Treated SUDs of alcohol and illicit substances identified in treatment registers; suicide attempt identified in treatment registers; and completed suicides identified in the Cause of Death register. Covariates were sex and age at diagnosis. Having any SUD was associated with at least a threefold increased risk of completed suicide when compared with those having no SUD. Alcohol misuse was associated with an increased risk of completed suicide in all populations with hazard ratios (HR) between 1.99 [95% confidence interval (CI) = 1.44-2.74] and 2.70 (95% CI = 2.40-3.04). Other illicit substances were associated with a two- to threefold risk increase of completed suicide in all populations except bipolar disorder, and cannabis was associated with increased risk of attempted suicide only in people with bipolar disorder (HR = 1.86, 95% CI = 1.15-2.99). Alcohol and other illicit substances each displayed strong associations with attempted suicide, HR ranging from 3.11 (95% CI = 2.95-3.27) to 3.38 (95% CI = 3.24-3.53) and 2.13 (95% CI = 2.03-2.24) to 2.27 (95% CI = 2.12-2.43), respectively. Cannabis was associated with suicide attempts only in people with schizophrenia (HR = 1.11, 95% CI = 1.03-1.19). Substance use disorders are associated strongly with risk of completed suicides and suicide attempts in people with severe mental illness. © 2017 Society for the Study of Addiction.

A diet with restricted energy content reduces the occurrence of cancer in animal experiments. It is not known if the underlying mechanism also exists in human beings. To determine whether cancer incidence is reduced among patients with anorexia nervosa who tend to have a low intake of energy, we carried out a retrospective cohort study of 22 654 women and 1678 men diagnosed with anorexia nervosa at ages 10-50 years during 1968-2010 according to National Hospital Registers in Sweden, Denmark and Finland. The comparison group consisted of randomly selected persons from population registers who were similar to the anorexia nervosa patients in respect to sex, year of birth and place of residence. Patients and population comparisons were followed for cancer by linkage to Cancer Registries. Incidence rate ratios (IRR) were estimated using Poisson models. In total, 366 cases of cancer (excluding non-melanoma skin cancer) were seen among women with anorexia nervosa, and the IRR for all cancer sites was 0.97 (95% CI = 0.87-1.08) adjusted for age, parity and age at first child. There were 76 breast cancers corresponding to an adjusted IRR of 0.61 (95% CI = 0.49-0.77). Significantly increased IRRs were observed for esophageal, lung, and liver cancer. Among men with anorexia nervosa, there were 23 cases of cancer (age-adjusted IRR = 1.08; 95% CI = 0.71-1.66). There seems to be no general reduction in cancer occurrence among patients with anorexia nervosa, giving little support to the energy restriction hypothesis. PMID:26000630

To describe and analyse oral health of children and adolescents under two types of dental health care schemes under the Public Dental Health Service in Denmark, and to analyse possible influence of socio-economic and socio-cultural factors. Data on children's oral health status was obtained from public oral health registers and were pooled with data from questionnaires sent to parents of the children and adolescents. The study comprised individuals aged 5, 12 and 15, in total 2168 persons, randomly drawn from four municipalities with dental care provided by salaried dentists in public dental clinics and three municipalities with dental care provided by dentists in private practice. 70% of the parents completed a questionnaire including questions on socio-economic and socio-cultural background, lifestyle-related factors, self assessment of parents' oral- and general health. After the data were merged, the final study population represented 60% of the original target population. The mean caries experience (DMFS+dmfs) was 2.2 and further analysis of caries experience in each age group showed no variations in relation to type of provider of dental care. However, multiple dummy regression analyses demonstrated that low education, poor general health, foreign citizenship and smoking habits of the parents were important determinants for high level of caries in their children. Occurrence of dental caries as well as changes over time in levels of dental caries of Danish children did not vary by scheme of Public Dental Health Service, i.e. whether dental health care was provided by public employed dentists or by private practitioners. However, social inequalities still relate to caries experience in children and adolescents. Adjustment of preventive oral health activities strategy seems to be needed.

Modern combination antiretroviral therapy (cART) has improved survival for people living with HIV (PLWHIV). Non-AIDS comorbidities have replaced opportunistic infections as leading causes of mortality and morbidity, and are becoming a key health concern as this population continues to age. The aim of this study is to estimate the prevalence and incidence of non-AIDS comorbidity among PLWHIV in Denmark in the cART era and to determine risk factors contributing to the pathogenesis. The study primarily targets cardiovascular, respiratory, and hepatic non-AIDS comorbidity. The Copenhagen comorbidity in HIV-infection (COCOMO) study is an observational, longitudinal cohort study. The study was initiated in 2015 and recruitment is ongoing with the aim of including 1500 PLWHIV from the Copenhagen area. Follow-up examinations after 2 and 10 years are planned. Uninfected controls are derived from the Copenhagen General Population Study (CGPS), a cohort study including 100,000 uninfected participants from the same geographical region. Physiological and biological measures including blood pressure, ankle-brachial index, electrocardiogram, spirometry, exhaled nitric oxide, transient elastography of the liver, computed tomography (CT) angiography of the heart, unenhanced CT of the chest and upper abdomen, and a number of routine biochemical analysis are uniformly collected in participants from the COCOMO study and the CGPS. Plasma, serum, buffy coat, peripheral blood mononuclear cells (PBMC), urine, and stool samples are collected in a biobank for future studies. Data will be updated through periodical linking to national databases. As life expectancy for PLWHIV improves, it is essential to study long-term impact of HIV and cART. We anticipate that findings from this cohort study will increase knowledge on non-AIDS comorbidity in PLWHIV and identify targets for future interventional trials. Recognizing the demographic, clinical and pathophysiological characteristics of comorbidity in PLWHIV may help inform development of new guidelines and enable us to move forward to a more personalized HIV care.

The International Agency for Research on Cancer has classified radiofrequency radiation as possibly carcinogenic. Previous studies have focused on intracranial tumors, although the skin receives much radiation. In a nationwide cohort study, 355,701 private mobile phone subscribers in Denmark from 1987 to 1995 were followed up through 2007. We calculated incidence rate ratios (IRRs) for melanoma, basal cell carcinoma, and squamous cell carcinoma by using Poisson regression models adjusted for age, calendar period, educational level, and income. Separate IRRs for head/neck tumors and torso/leg tumors were compared (IRR ratios) to further address potential confounders. We observed no overall increased risk for basal cell carcinoma, squamous cell carcinoma, or melanoma of the head and neck. After a follow-up period of at least 13 years, the IRRs for basal cell carcinoma and squamous cell carcinoma remained near unity. Among men, the IRR for melanoma of the head and neck was 1.20 (95% confidence interval: 0.65, 2.22) after a minimum 13-year follow-up, whereas the corresponding IRR for the torso and legs was 1.16 (95% confidence interval: 0.91, 1.47), yielding an IRR ratio of 1.04 (95% confidence interval: 0.54, 2.00). A similar risk pattern was seen among women, though it was based on smaller numbers. In this large, population-based cohort study, little evidence of an increased skin cancer risk was observed among mobile phone users.

A Nordic Semiconductor Meeting is held every other year with the venue rotating amongst the Nordic countries of Denmark, Finland, Iceland, Norway and Sweden. The focus of these meetings remains 'original research and science being carried out on semiconductor materials, devices and systems'. Reports on industrial activity have usually featured. The topics have ranged from fundamental research on point defects in a semiconductor to system architecture of semiconductor electronic devices. Proceedings from these events are regularly published as a Topical Issue of Physica Scripta. All of the papers in this Topical Issue have undergone critical peer review and we wish to thank the reviewers and the authors for their cooperation, which has been instrumental in meeting the high scientific standards and quality of the series. This 24th meeting of the Nordic Semiconductor community, NSM 2011, was held at Fuglsøcentret, close to Aarhus, Denmark, 19-22 June 2011. Support was provided by the Carlsberg Foundation, Danfysik and the semiconductor group at Aarhus University. Over 30 participants presented a broad range of topics covering semiconductor materials and devices as well as related material science interests. The conference provided a forum for Nordic and international scientists to present and discuss new results and ideas concerning the fundamentals and applications of semiconductor materials. The aim of the meeting was to advance the progress of Nordic science and thus aid in future worldwide technological advances concerning technology, education, energy and the environment. The 25th Nordic Semiconductor Meeting will be organized in June 2013 in Finland, chaired by Dr Filip Tuomisto, Aalto University. A Nordic Summer School on Semiconductor Science will be organized in connection with the conference (just before), chaired by Dr Jonatan Slotte, Aalto University.

The air pollutant levels over Denmark are simulated using the high resolution DEHM/UBM model system for the years 2006 to 2014. The system employs a hemispheric chemistry-transport model, the Danish Eulerian Hemispheric Model (DEHM; Brandt et al., 2012) that runs on a 150 km x 150 km resolution over the Northern Hemisphere, with nesting capability for higher resolutions over Europe, Northern Europe and Denmark on 50 km x 50 km, 16.7 km x 16.7 km and 5.6 km x 5.6 km resolutions, respectively, coupled to the Urban Background Model (UBM; Berkowicz, 2000; Brandt et al., 2001) that covers the whole of Denmark with a 1 km x 1 km spatial resolution. Over Denmark, the system uses the SPREAD emission model (Plejdrup and Gyldenkærne, 2011) that distributes the Danish emissions for all pollutants and all sectors in the national emission database on a 1 km x 1 km resolution grid covering Denmark and its national sea territory. The study will describe the model system and we will evaluate the performance of the model system in simulating hourly and daily ozone (O3), carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO2) and particulate matter (PM10 and PM2.5) concentrations against surface measurements from eight monitoring stations. Finally we investigate the spatial variation of air pollutants over Denmark on different time scales. References Berkowicz, R., 2000. A Simple Model for Urban Background Pollution.

We have carried out spectral analysis of measles notifications in several communities in Denmark, UK and USA. The results confirm that each power spectral density (PSD) shows exponential characteristics, which are universally observed in the PSD for time series generated from nonlinear dynamical system. The exponential gradient increases with the population size. For almost all communities, many spectral lines observed in each PSD can be fully assigned to linear combinations of several fundamental periods, suggesting that the measles data are substantially noise-free. The optimum least squares fitting curve calculated using these fundamental periods essentially reproduces an underlying variation of the measles data, and an extension of the curve can be used to predict measles epidemics. For the communities with large population sizes, some PSD patterns obtained from segment time series analysis show a close resemblance to the PSD patterns at the initial stages of a period-doubling bifurcation process for the so-called susceptible/exposed/infectious/recovered (SEIR) model with seasonal forcing. The meaning of the relationship between the exponential gradient and the population size is discussed.

We study workplace peer effects in fertility decisions using a game theory model of strategic interactions among coworkers that allows for multiple equilibria. Using register-based data on fertile-aged women working in medium sized establishments in Denmark, we uncover negative average peer effects. Allowing for heterogeneous effects by worker type, we find that positive effects dominate across worker types defined by age or education. Negative effects dominate within age groups and among low-education types. Policy simulations show that these estimated effects make the distribution of where women work an important consideration, beyond simply if they work, in predicting population fertility.

Objective Minority sexual orientation has been repeatedly linked to elevated rates of suicide attempts. Whether this translates into greater risk for suicide mortality is unclear. We investigated sexual orientation-related differences in suicide mortality in Denmark during the initial 12-year period following legalization of same-sex registered domestic partnerships (RDPs). Method Using data from death certificates issued between 1990 and 2001 and population estimates from the Danish census, we estimated suicide mortality risk among individuals classified into one of three marital/cohabitation statuses: current/formerly in same-sex RDPs; current/formerly heterosexually married; or never married/registered. Results Risk for suicide mortality was associated with this proxy indicator of sexual orientation, but only significantly among men. The estimated age-adjusted suicide mortality risk for RDP men was nearly eight times greater than for men with positive histories of heterosexual marriage and nearly twice as high for men who had never married. Conclusions Suicide risk appears greatly elevated for men in same-sex partnerships in Denmark. To what extent this is true for similar gay and bisexual men who are not in such relationships is unknown, but these findings call for targeted suicide prevention programs aimed at reducing suicide risk among gay and bisexual men.

The periodic health check-up has been a fundamental part of routine medical practice for decades, despite a lack of consensus regarding its value in health promotion and disease prevention. A large-scale Danish population-based preventive programme 'Check your health' was developed based on available evidence of screening and successive accepted treatment, prevention for diseases and health promotion, and is closely aligned with the current health care system.The objective of the 'Check your health' [CORE] trial is to investigate effectiveness on health outcomes of a preventive health check offered at a population-level to all individuals aged 30-49 years, and to establish the cost-effectiveness. The trial will be conducted as a pragmatic household-cluster randomised controlled trial involving 10,505 individuals. All individuals within a well-defined geographical area in the Central Denmark Region, Denmark (DK) were randomised to be offered a preventive health check (Intervention group, n = 5250) or to maintain routine access to healthcare until a delayed intervention (Comparison group, n = 5255). The programme consists of a health examination which yields an individual risk profile, and according to this participants are assigned to one of the following interventions: (a) referral to a health promoting consultation in general practice, (b) behavioural programmes at the local Health Centre, or (c) no need for follow-up.The primary outcomes at 4 years follow-up are: ten-year-risk of fatal cardiovascular event (Heart-SCORE model), physical activity level (self-report and cardiorespiratory fitness), quality of life (SF12), sick leave and labour market attachment. Cost-effectiveness will be evaluated according to life years gained, direct costs and total health costs. Intention to treat analysis will be performed. Results from the largest Danish health check programme conducted within the current healthcare system, spanning the sectors which share responsibility for the individual, will provide a scientific basis to be used in the development of systems to optimise population health in the 21st century. The trial has registered at ClinicalTrials.gov with an ID: NCT02028195 (7. March 2014).

Summary Background Animals can act as a reservoir and source for the emergence of novel meticillin-resistant Staphylococcus aureus (MRSA) clones in human beings. Here, we report the discovery of a strain of S aureus (LGA251) isolated from bulk milk that was phenotypically resistant to meticillin but tested negative for the mecA gene and a preliminary investigation of the extent to which such strains are present in bovine and human populations. Methods Isolates of bovine MRSA were obtained from the Veterinary Laboratories Agency in the UK, and isolates of human MRSA were obtained from diagnostic or reference laboratories (two in the UK and one in Denmark). From these collections, we searched for mecA PCR-negative bovine and human S aureus isolates showing phenotypic meticillin resistance. We used whole-genome sequencing to establish the genetic basis for the observed antibiotic resistance. Findings A divergent mecA homologue (mecALGA251) was discovered in the LGA251 genome located in a novel staphylococcal cassette chromosome mec element, designated type-XI SCCmec. The mecALGA251 was 70% identical to S aureus mecA homologues and was initially detected in 15 S aureus isolates from dairy cattle in England. These isolates were from three different multilocus sequence type lineages (CC130, CC705, and ST425); spa type t843 (associated with CC130) was identified in 60% of bovine isolates. When human mecA-negative MRSA isolates were tested, the mecALGA251 homologue was identified in 12 of 16 isolates from Scotland, 15 of 26 from England, and 24 of 32 from Denmark. As in cows, t843 was the most common spa type detected in human beings. Interpretation Although routine culture and antimicrobial susceptibility testing will identify S aureus isolates with this novel mecA homologue as meticillin resistant, present confirmatory methods will not identify them as MRSA. New diagnostic guidelines for the detection of MRSA should consider the inclusion of tests for mecALGA251.

The assessment of rare adverse events following vaccination may not be possible within a single country due to an insufficiently large denominator population. In 2008 a European consortium (VAESCO) was funded to perform collaborative vaccine safety studies. To help assess the feasibility of multi-country collaboration England and Denmark, who have established vaccine safety research infrastructures, undertook to work to a common protocol and share results and data to estimate the risk of a known true adverse event, thrombocytopenic purpura (TP) following measles-mumps-rubella (MMR) vaccination. TP is a known rare reaction to MMR and therefore provided an opportunity to assess whether two countries would produce similar results when working collaboratively. Despite some initial problems with ensuring data were comparable, the two countries gave very similar estimates of the relative incidence in the 6 weeks after vaccination and a pooled relative incidence estimate of 2.13 (95% confidence interval 1.55-2.94) and attributable risk of 1 in 50,000 doses. Both countries used hospital admissions for TP and the analysis was performed using the self controlled case series method which is particularly suited to collaborative studies because of its implicit control for individual level confounding. The study therefore shows the potential for vaccine safety collaborations across Europe to detect true associations through use of common protocols and sharing of results or data.

47,XXX syndrome is among the most common sex chromosomal disorders; however, apart from screening surveys, epidemiological data are limited. We report data on 136 women diagnosed with 47,XXX or a compatible karyotype in Denmark during 1963-2008. We identified an incidence of 10.7 per 100,000 liveborn girls, which was lower than expected and was stable during the study period. Age at diagnosis ranged from 0 to 73 years, with a diagnostic delay of 18.2 years or more in half the 47,XXX persons. We compared persons with 47,XXX with an age-matched cohort of the female background population (born same year and month), identified in Statistics Denmark (n = 13,400). Mortality was significantly increased in total with a hazard ratio of 2.5 (1.6-3.9), corresponding to a difference in median survival of 7.7 years. When we divided causes of death into 19 chapters according to the International Classification of Diseases, a generally increased mortality was identified in all informative chapters. Furthermore, we identified significantly increased mortality in cardiovascular diseases, in the chapter concerning chromosomal and congenital defects, and in the chapter of unspecified diseases. Better delineation of the clinical phenotype of 47,XXX is needed; available information does not readily explain the increased mortality. Copyright 2010 Wiley-Liss, Inc.

The impact of selection, gene flow and demographic history on heterogeneous genomic divergence: three-spine sticklebacks in divergent environments.

PubMed

Ferchaud, Anne-Laure; Hansen, Michael M

2016-01-01

Heterogeneous genomic divergence between populations may reflect selection, but should also be seen in conjunction with gene flow and drift, particularly population bottlenecks. Marine and freshwater three-spine stickleback (Gasterosteus aculeatus) populations often exhibit different lateral armour plate morphs. Moreover, strikingly parallel genomic footprints across different marine-freshwater population pairs are interpreted as parallel evolution and gene reuse. Nevertheless, in some geographic regions like the North Sea and Baltic Sea, different patterns are observed. Freshwater populations in coastal regions are often dominated by marine morphs, suggesting that gene flow overwhelms selection, and genomic parallelism may also be less pronounced. We used RAD sequencing for analysing 28 888 SNPs in two marine and seven freshwater populations in Denmark, Europe. Freshwater populations represented a variety of environments: river populations accessible to gene flow from marine sticklebacks and large and small isolated lakes with and without fish predators. Sticklebacks in an accessible river environment showed minimal morphological and genomewide divergence from marine populations, supporting the hypothesis of gene flow overriding selection. Allele frequency spectra suggested bottlenecks in all freshwater populations, and particularly two small lake populations. However, genomic footprints ascribed to selection could nevertheless be identified. No genomic regions were consistent freshwater-marine outliers, and parallelism was much lower than in other comparable studies. Two genomic regions previously described to be under divergent selection in freshwater and marine populations were outliers between different freshwater populations. We ascribe these patterns to stronger environmental heterogeneity among freshwater populations in our study as compared to most other studies, although the demographic history involving bottlenecks should also be considered in the interpretation of results. © 2015 John Wiley & Sons Ltd.

The objectives were to identify the impact of ergonomic work environment exposures on the risk of disability pension. A representative sample of 8475 employees of the total working population in Denmark were interviewed regarding work environment exposures and followed in a national register with data on granted disability pension. For women, approximately 34% of the disability pension cases were attributable to ergonomic work environment exposures. For men, 21% of the disability pension cases were attributable to ergonomic work environment. Ergonomic work environment, especially physically demanding work, working with hands lifted and repetitive work, are areas of intervention at the workplace that can facilitate and prolong labour market participation. The study provides estimates for the association between ergonomic exposures at work and administrative, cost-related measures of work disability in a large population-based longitudinal cohort study over 14 years. Approximately 21% for men and 34% for women of the disability pension cases were attributable to ergonomic work environment exposures.

Towards 50% wind electricity in Denmark: Dilemmas and challenges

Bach, Paul-Frederik

2016-05-01

Electricity and heat supply systems are essential contributors to a fossil-free future in Denmark. The combined production of heat and power (CHP) and the production of wind energy are already well developed in Denmark. Combined heat and power covers about 40% of the demand for space heating in Denmark, and the production of wind energy is supposed to exceed 50% of the demand for electricity by 2020. The changing electricity and heat production has some consequences already now: i) Decreasing wholesale prices in Denmark and in other countries. ii) Thermal power plants are closing down. Denmark is no longer self-sufficient with electricity under all conditions. iii) The electricity production pattern does not match the demand pattern. The result is that the neighbouring countries must absorb the variations from wind and solar power. Essential challenges: i) The future of combined heat and power in Denmark is uncertain. ii) Denmark will need new backup capacity for filling the gaps in wind power and solar cell output. iii) Flexible electricity consumers are supposed to contribute to balancing the future power systems. There is still a long way to go before the Smart Grid visions are implemented in large scale. iv) The transformation of the power system will create new risks of power failures.

In Denmark the development of rehabilitation of patients with acquired brain injury (ABI) has differed from most parts of Europe. Denmark has no medical rehabilitation specialty. In 2000 two specialized hospital units were established to serve the population of 5.7 million inhabitants. They cover the needs of patients with the most severe ABIs. Only recently rehabilitation of patients with ABI has been anchored in the medical specialty of neurology. Since then the development has taken an up-going curve. This process has been supported by The Danish Health and Medicines Authority publishing several papers that highlights evidence-based organization and interventions. Current development aim to define: 1) skills of the medical doctor engaged in the rehabilitation of patients with ABI, 2) stratification to different levels of specialization at hospital and in the community, and 3) national guidelines that specify skills and collaboration between groups of professionals working with ABI rehabilitation.

Schack Petersen, Merete Binderup Geological Survey of Denmark and Greenland (GEUS), Øster Voldgade 10, 1350 Copenhagen, Denmark, * email address bn@geus.dk The Danish Parliament decided in 2003 that the temporal disposal of the low- and intermediate level radioactive waste at the nuclear facilities at Risø should find another location for a final repository. The Danish radioactive waste must be stored on Danish land territory (exclusive Greenland) and must hold the entire existing radioactive waste, consisting of the waste from the decommissioning of the nuclear facilities at Risø, and the radioactive waste produced in Denmark from hospitals, universities and industry. The radioactive waste is estimated to a total amount of up to 10,000 m3. The Geological Survey of Denmark and Greenland, GEUS, is responsible for the geological studies of suitable areas for the repository. The task has been to locate and recognize non-fractured Quaternary and Tertiary clays or Precambrian bedrocks with low permeability which can isolate the radioactive waste from the surroundings the coming more than 300 years. Twenty two potential areas have been located and sequential reduced to the most favorable two to three locations taking into consideration geology, hydrogeology, nature protection and climate change conditions. Further detailed environmental and geology investigations will be undertaken at the two to three potential localities in 2013 to 2015. This study together with a study of safe transport of the radioactive waste and an investigation of appropriate repository concepts in relation to geology and safety analyses will constitute the basis upon which the final decision by the Danish Parliament on repository concept and repository location. The final repository is planned to be established and in operation at the earliest 2020.

Prisoners constitute a high-risk population, particularly for infectious diseases. The aim of this study was to estimate the level of infectious risk in the prisons of five different European countries by measuring to what extent the prison system adheres to WHO/UNODC recommendations. Following the methodology used in a previous French survey, a postal/electronic questionnaire was sent to all prisons in Austria, Belgium, Denmark and Italy to collect data on the availability of several recommended HIV-HCV prevention interventions and HBV vaccination for prisoners. A score was built to compare adherence to WHO/UNODC recommendations (considered a proxy of environmental infectious risk) in those 4 countries. It ranged from 0 (no adherence) to 12 (full adherence). A second score (0 to 9) was built to include data from a previous French survey, thereby creating a 5-country comparison. A majority of prisons answered in Austria (100 %), France (66 %) and Denmark (58 %), half in Belgium (50 %) and few in Italy (17 %), representing 100, 74, 89, 47 and 23 % coverage of the prison populations, respectively. Availability of prevention measures was low, with median adherence scores ranging from 3.5 to 4.5 at the national level. These results were confirmed when using the second score which included France in the inter-country comparison. Overall, the adherence score was inversely associated with prison overpopulation rates (p = 0.08). Using a score of adherence to WHO/UNODC recommendations, the estimated environmental infectious risk remains extremely high in the prisons of the 5 European countries assessed. Public health strategies should be adjusted to comply with the principle of equivalence of care and prevention with the general community.

Framing (implicitly) matters: the role of religion in attitudes toward immigrants and Muslims in Denmark.

PubMed

Anderson, Joel; Antalíková, Radka

2014-12-01

Denmark is currently experiencing the highest immigration rate in its modern history. Population surveys indicate that negative public attitudes toward immigrants actually stem from attitudes toward their (perceived) Islamic affiliation. We used a framing paradigm to investigate the explicit and implicit attitudes of Christian and Atheist Danes toward targets framed as Muslims or as immigrants. The results showed that explicit and implicit attitudes were more negative when the target was framed as a Muslim, rather than as an immigrant. Interestingly, implicit attitudes were qualified by the participants' religion. Specifically, analyses revealed that Christians demonstrated more negative implicit attitudes toward immigrants than Muslims. Conversely, Atheists demonstrated more negative implicit attitudes toward Muslims than Atheists. These results suggest a complex relationship between religion, and implicit and explicit prejudice. Both the religious affiliation of the perceiver and the perceived religious affiliation of the target are key factors in social perception. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

National differences in the legislation on cause and manner of death investigation are reflected in a high autopsy rate in suicides in Finland and a low corresponding rate in Denmark. The consequences for mortality statistics of these different investigation practices on deaths classified as suicides in Denmark and Finland, respectively, are not known in detail. The aim of this article was to analyse autopsy rates in deaths classified as suicides, and to identify any differences in investigation practices in deaths with a comparable cause of death, but classified as unnatural deaths other than suicide. Data from the mortality registries were summarised for the years 2000, 2005 and 2010. Autopsy rates (total, forensic and medical) were analysed with regard to deaths classified as suicide, and they were compared for three age groups (1-50 years, 51-70 years and ≥71 years) and for causes of death. Deaths classified as suicide were compared with other unnatural classifications, and comparable causes of death were coded into six subgroups: poisonings, suffocations/strangulations, firearm discharges, drowning/submersions, explosions/flames and other/unspecified causes. The total autopsy rate for suicides was 99.8% in Finland and 13.2% in Denmark. Almost all of these autopsies were conducted as forensic autopsies. In the age group ≥71 years, Danish suicides outnumbered Finnish suicides (410 versus 283). The total autopsy rate was lower in the more senior age group in Denmark (19.5%, 9.9%, 5.6%), whereas it was consistently high in Finland (99.8%, 99.9%, 99.6%). Among Danish deaths due to poisonings, the autopsy rate was 89.5% when these were classified as accidents, but only 20.7% for cases classified as suicides. The number of deaths in the two Danish subgroups was comparable (550 versus 553). In Denmark, the decision regarding the need, if any, for a forensic autopsy is made during the external forensic examination of the body. Our study showed that the limited use of forensic autopsy to confirm the cause of death in deaths classified as suicides raises doubts about the accuracy of the Danish suicide mortality statistics. Our finding is emphasised by those cases in which the cause of death was registered as intentional self-poisoning. The high number of suicides among the elderly in Denmark is striking and begs further investigation and research. Overall, our data from Finland and Denmark reveal striking differences between the two countries and warrant further comparative studies on the subject in other countries.

Guidelines recommend that patients with gastro-oesophageal reflux disease are adequately treated with acid-suppressive therapy before undergoing anti-reflux surgery. Little is known of the use of acid-suppressive drugs before anti-reflux surgery. To determine the use of proton pump inhibitors and H2 -receptor antagonists in the year before anti-reflux surgery. A nationwide retrospective study of all patients aged ≥18 undergoing first-time anti-reflux surgery in Denmark during 2000-2012 using data from three different sources: the Danish National Register of Patients, the Danish National Prescription Register, and the Danish Person Register. The study population thus included 2922 patients (median age: 48 years, 55.7% male). The annual proportion of patients redeeming ≥180 DDD of acid-suppressive therapy increased from 17.0% 5 years before anti-reflux surgery to 64.9% 1 year before. The probability for inadequate dosing 1 year before surgery (<180 DDD) was significantly increased for younger patients, patients operated in the period 2000-2003, patients who had not undergone pre-surgical manometry, pH- or impedance monitoring, and patients who had not redeemed prescriptions on NSAID or anti-platelet drugs. Compliance with medical therapy should be evaluated thoroughly before planning anti-reflux surgery, as a high proportion of patients receive inadequate dosing of acid-suppressive therapy prior to the operation. © 2015 John Wiley & Sons Ltd.

Adolescent smoking is still highly prevalent in Denmark. One in four 13-year olds indicates that they have tried to smoke, and one in four 15-year olds answer that they smoke regularly. Smoking is more prevalent in socioeconomically disadvantaged populations in Denmark as well as in most Western countries. Previous school-based programs to prevent smoking have shown contrasting results internationally. In Denmark, previous programs have shown limited or no effect. This indicates a need for developing a well-designed, comprehensive, and multi-component intervention aimed at Danish schools with careful implementation and thorough evaluation.This paper describes X:IT, a study including 1) the development of a 3-year school-based multi-component intervention and 2) the randomized trial investigating the effect of the intervention. The study aims at reducing the prevalence of smoking among 13 to 15-year olds by 25%. The X:IT study is based on the Theory of Triadic Influences. The theory organizes factors influencing adolescent smoking into three streams: cultural environment, social situation, and personal factors. We added a fourth stream, the community aspects. The X:IT program comprises three main components: 1) smoke-free school premises, 2) parental involvement including smoke-free dialogues and smoke-free contracts between students and parents, and 3) a curricular component. The study encompasses process- and effect-evaluations as well as health economic analyses. Ninety-four schools in 17 municipalities were randomly allocated to the intervention (51 schools) or control (43 schools) group. At baseline in September 2010, 4,468 year 7 students were eligible of which 4,167 answered the baseline questionnaire (response rate = 93.3%). The X:IT study is a large, randomized controlled trial evaluating the effect of an intervention, based on components proven to be efficient in other Nordic settings. The X:IT study directs students, their parents, and smoking prevention policies at the schools. These elements have proven to be effective tools in preventing smoking among adolescents. Program implementation is thoroughly evaluated to be able to add to the current knowledge of the importance of implementation. X:IT creates the basis for thorough effect and process evaluation, focusing on various social groups. Current Controlled Trials ISRCTN77415416.

Aim of database To systematically monitor and improve the quality of treatment and care of patients with schizophrenia in Denmark. In addition, the database is accessible as a resource for research. Study population Patients diagnosed with schizophrenia and receiving mental health care in psychiatric hospitals or outpatient clinics. During the first year after the diagnosis, patients are classified as incident patients, and after this period as prevalent patients. Main variables The registry currently contains 21 clinical quality measures in relation to the following domains: diagnostic evaluation, antipsychotic treatment including adverse reactions, cardiovascular risk factors including laboratory values, family intervention, psychoeducation, postdischarge mental health care, assessment of suicide risk in relation to discharge, and assessment of global functioning. Descriptive data The recorded data are available electronically for the reporting clinicians and responsible administrative personnel, and they are updated monthly. The registry publishes the national and regional results of all included quality measures in the annual audit reports. External researchers may obtain access to the data for use in specific research projects by applying to the steering committee. Conclusion The Danish Schizophrenia Registry represents a valuable source of informative data to monitor and improve the quality of care of patients with schizophrenia in Denmark. However, continuous resources and time devoted is necessary to maintain the integrity of the registry and the validity of the data. PMID:27843348

Breeding programmes for warmblood sport horses are similar in the Nordic countries Sweden, Denmark, Finland and Norway, and stallions of same origin are used. The aim was to investigate whether a joint Nordic genetic evaluation based on lifetime competition performance is feasible and beneficial for breeding competitive sport horses in the Nordic countries. Results for almost 45,000 horses in show jumping and 30,000 horses in dressage were available. The larger populations in Sweden and Denmark contributed with 85% of the results. Heritabilities and genetic correlations between performances in the different countries were estimated, and comparisons of accuracies of estimated breeding values (EBVs) and number of stallions with EBVs based on national or joint data were studied. The heritabilities ranged between 0.25 and 0.42 for show jumping and between 0.14 and 0.55 for dressage. The genetic correlations between competition performances in the Nordic countries were estimated to 0.63-1.00. EBVs based on joint data increased accuracies for EBVs for stallions by 38-81% and increased the number of available stallions with EBVs by 40-288%, compared to EBVs based on national data only. A joint Nordic genetic evaluation for sport horses is recommended. © 2015 Blackwell Verlag GmbH.

Objectives: To estimate the prevalence of four types of childhood maltreatment in Denmark while taking into considerations how each of the types of maltreatment vary as a function of gender or child-protection status. Methods: Data were collected from a Danish national study conducted by The Danish National Centre for Social Research in 2008 and 2009. The study used a stratified random probability sample of young people aged 24 years. A sample of 4718 young adults were randomly selected by Statistics Denmark using the total birth cohort of all children born in 1984. The response rate was 63% leaving a total effective sample size of 2980. A structured residential or telephone interview enquired about a range of respondents maltreatment experiences. Results: Maltreatment is experienced by a significant proportion of Danish children. The reported prevalence rates were; physical neglect (3.0%), emotional abuse (5.2%), physical abuse (5.4%) and sexual abuse (3.4%). All trauma types were experienced by a greater percentage of females compared to males with the exception of physical abuse and all trauma types were experienced by a greater percentage of children given child-protection status. Conclusions: Female children and children who are given child protection status are those most at risk for experiencing maltreatment in Denmark. However, variability in prevalence rates of maltreatment across studies is problematic. Methodological variations and variation in abuse definitions may be partly attributable. PMID:24155769

Smaller studies indicate that the incidence of pyogenic spondylodiscitis is increasing, possible related to a growing elderly population. Data supporting this is sparse, and we therefore studied patient characteristics and changes in spondylodiscitis incidence 1995-2008. In a population-based study we identified all patients aged ≥18 years treated for pyogenic spondylodiscitis in Funen County, Denmark (population 483 123). Annual incidences were determined. Demographics, symptoms and diagnostic methods were recorded. We found 192 cases: median age 66.6 years; 57.3% men; 76.6% culture positive cases. Staphylococcus aureus was the most common pathogen (55.1%). During 1995-2008 the overall incidence, incidence of culture negative cases, and incidence of cases due to S. aureus increased 2.2-5.8, 0.3-1.8, and 1.6-2.5 cases per 100 000 person years, respectively. The elderly had the highest incidence compared to those aged ≤70 years (rate ratio for men 5.9 (95% CI: 4.2-8.5) and for women 3.5 (95% CI: 2.3-5.3)). During 1995-2008 the overall incidence of S. aureus and culture negative cases of spondylodiscitis increased and remained highest among the elderly. Whether the increase is real or is a result of improved diagnostic methods and workup remains unknown. Copyright © 2013 The British Infection Association. Published by Elsevier Ltd.

Summary Background Cancer survival is a key measure of the effectiveness of health-care systems. Persistent regional and international differences in survival represent many avoidable deaths. Differences in survival have prompted or guided cancer control strategies. This is the first study in a programme to investigate international survival disparities, with the aim of informing health policy to raise standards and reduce inequalities in survival. Methods Data from population-based cancer registries in 12 jurisdictions in six countries were provided for 2·4 million adults diagnosed with primary colorectal, lung, breast (women), or ovarian cancer during 1995–2007, with follow-up to Dec 31, 2007. Data quality control and analyses were done centrally with a common protocol, overseen by external experts. We estimated 1-year and 5-year relative survival, constructing 252 complete life tables to control for background mortality by age, sex, and calendar year. We report age-specific and age-standardised relative survival at 1 and 5 years, and 5-year survival conditional on survival to the first anniversary of diagnosis. We also examined incidence and mortality trends during 1985–2005. Findings Relative survival improved during 1995–2007 for all four cancers in all jurisdictions. Survival was persistently higher in Australia, Canada, and Sweden, intermediate in Norway, and lower in Denmark, England, Northern Ireland, and Wales, particularly in the first year after diagnosis and for patients aged 65 years and older. International differences narrowed at all ages for breast cancer, from about 9% to 5% at 1 year and from about 14% to 8% at 5 years, but less or not at all for the other cancers. For colorectal cancer, the international range narrowed only for patients aged 65 years and older, by 2–6% at 1 year and by 2–3% at 5 years. Interpretation Up-to-date survival trends show increases but persistent differences between countries. Trends in cancer incidence and mortality are broadly consistent with these trends in survival. Data quality and changes in classification are not likely explanations. The patterns are consistent with later diagnosis or differences in treatment, particularly in Denmark and the UK, and in patients aged 65 years and older.

The tobacco problem in Denmark and the difficulties in implementing an organized plan of action.

PubMed

Egsmose, T

1985-08-01

In Denmark tobacco consumption has increased considerably during the last few decades. Almost 2 million people of a population of 5 million are smokers. Of the male population 48% are smokers, of the female population 46%. From 1981 to 1982 the cigarette consumption increased from 7,300 million to 8,000 million. Consumption of pipe tobacco increased slightly, whereas cigars and cigarillos were considerably reduced. The tobacco tax amounts to 6,500 million Dan. kr. annually (700 million US$). The tobacco industry's cost of marketing tobacco products are unknown, but advertising, for one thing, amounts to 25 million Dan.kr. annually (3 million US$), which is only a small fraction of the total cost of marketing. For comparison: On health information some 2 million Dan.kr. is spent annually by private associations. In 1970 and 1981 efforts were made to have a tobacco bill passed in the Danish Parliament-but with no success. Since 1972 there has been a gentleman's agreement between the ministry and the tobacco branch concerning the size and the content of tobacco advertising. The agreement was an evasive action initiated by the tobacco branch. During the tobacco bill debate in the Danish Parliament in 1981 the tobacco industry launched an aggressive and misleading advertising campaign in the large newspapers against the Minister of Interior. It says in the International Codes of Marketing Practice 1973 set forth by the International Chamber of Commerce: "all advertising should be legal, decent, honest and truthful" and "the advertisements should be prepared with due sense of social responsibility..".(ABSTRACT TRUNCATED AT 250 WORDS)

Umbilical and epigastric hernia repair are common surgical procedures; however, the nationwide gender and age-specific prevalence of these repairs is unknown, and this knowledge could form the basis for new studies. A nationwide register-based study covering all people living in Denmark on December 31st, 2010 was performed. Within this population all umbilical and epigastric hernia repairs from January 1st, 2006 to December 31st, 2010 were identified using data from the Danish National Hospital Register, and 5-year prevalence estimates were calculated. The study population covered 5,639,885 persons (49 % males). A total of 10,107 patients (68 % males) were operated for an umbilical hernia and 2412 patients (55 % males) were operated for an epigastric hernia. The age-specific 5-year prevalence differed for both hernia types. The highest 5-year prevalence of umbilical hernia repairs was seen in males aged 60-70 years with a 5-year prevalence of 0.53 % (95 % CI 0.51-0.56 %) and the highest age-specific 5-year prevalence of epigastric hernia repair was seen in 40-50 year females with a 5-year prevalence of 0.086 % (95 % CI 0.077-0.095 %). The gender and age-specific 5-year prevalence of umbilical and epigastric hernia repair differed in a nationwide population.

Excessive alcohol consumption increases the risk of many diseases and injuries, and the Global Burden of Disease 2010 study estimated that 6% of the burden of disease in Denmark is due to alcohol consumption. Alcohol consumption thus places a considerable economic burden on society. We analysed the cost-effectiveness of six interventions aimed at preventing alcohol abuse in the adult Danish population: 30% increased taxation, increased minimum legal drinking age, advertisement bans, limited hours of retail sales, and brief and longer individual interventions. Potential health effects were evaluated as changes in incidence, prevalence and mortality of alcohol-related diseases and injuries. Net costs were calculated as the sum of intervention costs and cost offsets related to treatment of alcohol-related outcomes, based on health care costs from Danish national registers. Cost-effectiveness was evaluated by calculating incremental cost-effectiveness ratios (ICERs) for each intervention. We also created an intervention pathway to determine the optimal sequence of interventions and their combined effects. Three of the analysed interventions (advertising bans, limited hours of retail sales and taxation) were cost-saving, and the remaining three interventions were all cost-effective. Net costs varied from € -17 million per year for advertisement ban to € 8 million for longer individual intervention. Effectiveness varied from 115 disability-adjusted life years (DALY) per year for minimum legal drinking age to 2,900 DALY for advertisement ban. The total annual effect if all interventions were implemented would be 7,300 DALY, with a net cost of € -30 million. Our results show that interventions targeting the whole population were more effective than individual-focused interventions. A ban on alcohol advertising, limited hours of retail sale and increased taxation had the highest probability of being cost-saving and should thus be first priority for implementation.

Assessment of the prevaccination type-specific prevalence of human papillomavirus (HPV) in the general population is important for the prediction of the impact of HPV vaccination. We collected consecutively residual specimens from liquid-based cytology samples from 40,382 women from the general population in Copenhagen, Denmark, during 2002-2005. All samples were tested for high-risk HPV using the Hybrid Capture 2 technique, and genotyping was done using LiPa (Innogenetics). Through linkage with the Pathology Data Bank, we obtained information on the cytology result, and histology if any, on all women. The participants were 14-95 years of age (median age 37 years) at enrollment. The overall prevalence of HR HPV was 20.6 % ranging from 46.0 % in 20-23-year-old women to 5.7 % in women 65 years or older. Independently of cytology/histology, HPV16 was the most prevalent type. For virtually all HPV types, the occurrence of CIN3+ was higher when the specific HPV type was present together with HPV16 than it was together with other high-risk HPV types than HPV16 or if the HPV type occurred as a single infection. The prevalence of HPV16 and/or HPV18 was 74 % in cervical cancer and the corresponding prevalence of HPV16/18/31/33/45/52/58 was 89 %. This study forms a valuable starting point for monitoring the effect of HPV vaccination in Denmark. In addition, the particular carcinogenic role of HPV16 and 18 is confirmed and may support a role of genotyping for HPV16 and 18 in cervical cancer screening.

2014-03-01

Although several studies have examined the relative contributions of familial and environmental risk factors for schizophrenia, few have additionally examined the predictive power on the individual level and simultaneously examined the population impact associated with a wide range of familial and environmental risk factors. The authors present rate ratios (IRR), population-attributable risks (PAR) and sex-specific cumulative incidences of the following risk factors: parental history of mental illness, urban place of birth, advanced paternal age, parental loss and immigration status. We established a population-based cohort of 2,486,646million persons born in Denmark between 1 January 1955 and 31 December 1993 using Danish registers. We found that PAR associated with urban birth was 11.73%; PAR associated with one, respectively 2, parent(s) with schizophrenia was 2.67% and 0.12%. PAR associated with second-generation immigration was 0.70%. Highest cumulative incidence (CI=20.23%; 95% CI=18.10-22.62) was found in male offspring of 2 parents with schizophrenia. Cumulative incidences for male offspring or female offspring of a parent with schizophrenia were 9.53% (95% CI=7.71-11.79), and 4.89%, (95% CI 4.50-5.31). The study showed that risk factors with highest predictive power on the individual level have a relatively low population impact. The challenge in future studies with direct genetic data is to examine gene-environmental interactions that can move research beyond current approaches and seek to achieve higher predictive power on the individual level and higher population impact.

Registry-Based Surveillance of Influenza-Associated Hospitalisations during the 2009 Influenza Pandemic in Denmark: The Hidden Burden on the Young

PubMed Central

Widgren, Katarina; Nielsen, Jens; Mølbak, Kåre

2010-01-01

Background To follow the impact of the 2009 influenza pandemic in Denmark, influenza surveillance was extended with a system monitoring potentially influenza-associated hospitalisations. Methodology/Principal Findings National administrative data from 2004–2010 from the automatic reporting of all hospital visits and admissions in Denmark (population 5.5 million) were used. In-patient hospitalisations linked to ICD-10 codes for potentially influenza-associated conditions (influenza, viral and bacterial pneumonia, respiratory distress, and febrile convulsion) were aggregated by week and age groups; <5 years, 5–24 years, 25–64 years and ≥65 years. Weekly numbers of influenza-associated hospitalisations were plotted to follow the course of the pandemic. We calculated the total numbers of influenza-associated hospitalisations in each influenza season (week 30 to week 15, the following year). Risk ratios of being admitted with an influenza-associated condition in this season (2009/2010) compared to the previous five seasons (2004/2005–2008/2009) were calculated using binary regression. During the pandemic season, influenza-associated hospitalisations peaked in week 47, 2009. The total number of influenza-associated hospitalisations was 38,273 compared to the median of previous seasons of 35,662 (p = 0.28). The risk ratio of influenza-associated hospitalisations during the pandemic season compared to previous seasons was 1.63 (95%CI 1.49–1.78) for 5–24 year-olds and ranged between 0.98 and 1.08 for the other three age groups. Conclusions The 2009 pandemic influenza did not lead to an overall increase in the number of influenza-associated hospitalisations in Denmark in the 2009/2010 season and could be managed within existing hospital capacity. However, there was a disproportionally large impact on the age group 5–24 years. The influenza-associated hospitalisations during the 2009/2010 pandemic influenza season bore the signature features of historical pandemics: A skewed age-pattern and early out of season transmission.

Malignant melanoma (MM) is increasing rapidly in Northern Europe. To reduce incidence and mortality through earlier diagnosis, public awareness of MM is important. Thus, we aim to examine awareness of risk factors and a symptom of MM, and how awareness varies by country and socio-demographic factors in Denmark, Northern Ireland (NI), Norway and Sweden. Population-based telephone interviews using the 'Awareness and Beliefs about Cancer' measure were conducted in 2011 among 8355 adults ≥50 years as part of the International Cancer Benchmarking Partnership Module 2. Prevalence ratios (PRs) with 95% confidence intervals were calculated. In these four countries, lowest awareness was found for 'sunburn in childhood' (63%), whereas awareness was high for 'use of sunbeds' (91%) and 'mole change' (97%). Lack of awareness of 'sunburn in childhood' was more prevalent among respondents from Norway [PR = 1.38 (1.28-1.48)] but less prevalent among respondents from Northern Ireland (NI) [PR = 0.78 (0.72-0.85)] and Sweden [PR = 0.86 (0.79-0.93)] compared with respondents from Denmark. Lack of awareness of 'use of sunbeds' was more prevalent among respondents from Norway [PR = 2.99 (2.39-3.74)], Sweden [PR = 1.57 (1.22-2.00)], and NI [PR = 1.65 (1.30-2.10)] compared with respondents form Denmark. Being a man, age ≥70, living alone, and having lower education, were each independently associated with lack of MM-awareness. The results indicate relatively low awareness of 'sunburn in childhood' as a risk factor for MM, and important disparities in MM-awareness across countries and socio-demographic groups. Improved and more directed initiatives to enhance public MM-awareness, particularly about 'sunburn in childhood', are needed. © The Author 2015.

Barriers among Danish women and general practitioners to raising the issue of intimate partner violence in general practice: a qualitative study

PubMed Central

2014-01-01

Background Thirty-five percent of Danish women experience sexual or physical violence in their lifetime. However, health care professionals are not in the practice of asking about intimate partner violence (IPV) in Denmark. It is currently unknown what hinders general practitioners from asking about partner violence and how Danish women would perceive such an inquiry. This aspect has not previously been explored in Denmark. An exploratory study was conducted to examine what hinders general practitioners (GPs) from asking and what Danish women’s views and attitudes are regarding being asked about IPV. Methods Data were collected through individual and group interviews with a sample of three GPs and a diverse sample of 13 women, including both survivors of partner violence and those without any history of partner violence. An interpretative analysis was performed with the data. Results This study provides important knowledge regarding the barriers and attitudes towards inquiry about IPV in primary care in Denmark. Results indicate that Denmark is facing the same challenges when responding to survivors of IPV as other similar countries, including Sweden, Norway, the UK, USA, and Australia. Danish women want general practitioners to ask about violence in a respectful and non-judgemental manner. However, general practitioners are resistant towards such an inquiry and would benefit from training regarding how to respond to women who have been exposed to IPV. Conclusions It is acceptable to inquire about IPV with women in Denmark in a non-judgemental and respectful way. Informing about IPV prevalence is important prior to the inquiry. However, general practitioners require more awareness and training before a favourable environment for this change in procedure can be created. Further large-scale research is needed to support the evidence generated by this small study. PMID:24893567

Jørgensen, Kirsten; Laursen, Bjarne

2013-02-01

The aim of the present study was to investigate absence from work in Denmark due to occupational and non-occupational accidents. Since the beginning of the last decade, political focus has been placed on the population's working capacity and the scope of absence due to illness. Absence from work is estimated at between 3% and 6% of working hours in the EU and costs are estimated at approximately 2.5% of GNP. Victims of accidents treated at two emergency departments were interviewed regarding absence for the injured, the family and others. All answers were linked to the hospital information on the injury, so that it was possible to examine the relation between absence and injury type, and cause of the accident. In total, 1,479 injured persons were interviewed. 36% of these reported absence from work by themselves or others. In mean, an injury caused 3.21 days of absence. Based on this the total absence due to injuries in Denmark was estimated to 1,822,000 workdays, corresponding to approximately 6% of the total absence from work due to all types of illness. Non-occupational injuries resulted in more absence than did occupational injuries. Absence due to accidents contributed to a considerable part of the total absence from work, and non-occupational accidents caused more absence than did occupational accidents.

Adjustment of hunting season length is often used to regulate harvest of waterbirds but the effects are disputed. We describe the first results of season length extension on the harvest of the pink-footed goose, which has been selected as the first test case of adaptive harvest management of waterbirds in Europe. In Denmark, the season (previously 1 September to 31 December) was extended to include January in 2014-15 with the aim to increase the harvest and, in the longer term, reduce the population size. The total harvest in Denmark increased by 52% compared to previous years, and almost 50% of the Danish harvest was taken in the January extension. In the course of the hunting season, the proportion of adults in the bag increased. In this case, the outcomes from the first extension of season suggest that season length adjustment can be an effective tool to regulate harvest, though dependent on winter weather conditions and hunters’ motivation for shooting geese.

Sex differences in mortality in Denmark during half a century, 1943-92.

Helweg-Larsen, K; Juel, K

2000-09-01

The emphasis of this study is on the relative mortality of 45-74-year-old men and women in Denmark in 1943-92, following economic and political changes that have affected the social meaning of gender over the last 50 years, and which have diminished former sex differences in health behaviour. Sex ratios of total mortality and mortality from major non-sex-specific causes of death were calculated on computerized mortality data from the Danish National Cause of Death Register that covers all deaths in Denmark since 1943. In the early 1940s the sex ratio of all-cause mortality was low, 1.0-1.1, it increased to a peak level in the late 1970s and early 1980s, but has since decreased due to an increase in female mortality and a more favourable trend in male mortality. Gender equality, employment, and economic autonomy may have beneficial health effects on both men and women, but the effects are inconsistent. The trend in smoking is the major explanatory factor for the more recent trends in gender differentials in mortality in Denmark.

To evaluate recreational and medical cannabis use in individuals with traumatic spinal cord injury, including reasons and predictors for use, perceived benefits and negative consequences. Cross-sectional survey in Denmark. A 35-item questionnaire was sent to 1,101 patients with spinal cord injury who had been in contact with a rehabilitation centre between 1990 and 2012. A total of 537 participants completed the questionnaire. Of these, 36% had tried cannabis at least once and 9% were current users. Of current users, 79% had started to use cannabis before their spinal cord injury. The main reason for use was pleasure, but 65% used cannabis partly for spinal cord injury-related consequences and 59% reported at least good effect on pain and spasticity. Negative consequences of use were primarily inertia and feeling quiet/subdued. Lower age, living in rural areas/larger cities, tobacco-smoking, high alcohol intake and higher muscle stiffness were significantly associated with cannabis use. Those who had never tried cannabis reported that they would mainly use cannabis to alleviate pain and spasticity if it were legalized. Cannabis use is more frequent among individuals with spinal cord injury in Denmark than among the general population. High muscle stiffness and various demographic characteristics (lower age, living in rural areas/larger cities, tobacco-smoking and high alcohol intake) were associated with cannabis use. Most participants had started using cannabis before their spinal cord injury. There was considerable overlap between recreational and disability-related use.

Chronic inflammatory diseases may be associated with anaemia of inflammation. Hidradenitis suppurativa is a chronic inflammatory dermatological disease associated with metabolic comorbidities, low quality of life and fatigue. Anaemia may cause fatigue, and it has been hypothesized that HS-related fatigue may be partly due to anaemia. Our objective was to investigate a possible association between HS and anaemia. We performed a hospital-based and population-based cross-sectional study investigating the red blood cell profile, i.e. haemoglobin. We identified a total of 32 hospital HS individuals, 430 population HS individuals and 20,780 population non-HS control individuals. The age-sex-smoking-adjusted analyses showed no differences in the haemoglobin level of the HS groups vs. the control group. Analyses of the anaemic subgroup of HS individuals revealed that 60% had normocytic anaemia and 40% microcytic anaemia, in concordance with anaemia of inflammation. In contrast to our hypothesis, this study showed that HS is not associated with anaemia. Thus, anaemia may not be the cause of the described fatigue in HS patients. Furthermore, the results indicate that if an HS patient does suffer from anaemia it is most likely to be normocytic or microcytic and thus compatible with anaemia seen in other chronic inflammatory disorders. © 2015 European Academy of Dermatology and Venereology.

Trauma is a leading cause of death among adults aged < 44 years, and optimal care is a challenge. Evidence supports the centralization of trauma facilities and the use multidisciplinary trauma teams. Because knowledge is sparse on the existing distribution of trauma facilities and the organisation of trauma care in Denmark, the aim of this study was to identify all Danish facilities that care for traumatized patients and to investigate the diversity in organization of trauma management. We conducted a systematic observational cross-sectional study. First, all hospitals in Denmark were identified via online services and clarifying phone calls to each facility. Second, all trauma care manuals on all facilities that receive traumatized patients were gathered. Third, anesthesiologists and orthopedic surgeons on call at all trauma facilities were contacted via telephone for structured interviews. A total of 22 facilities in Denmark were found to receive traumatized patients. All facilities used a trauma care manual and all had a multidisciplinary trauma team. The study found three different trauma team activation criteria and nine different compositions of teams who participate in trauma care. Training was heterogeneous and, beyond the major trauma centers, databases were only maintained in a few facilities. The study established an inventory of the existing Danish facilities that receive traumatized patients. The trauma team activation criteria and the trauma teams were heterogeneous in both size and composition. A national database for traumatized patients, research on nationwide trauma team activation criteria, and team composition guidelines are all called for.

Sick-leave decisions for patients with severe subjective health complaints presenting in primary care: A cross-sectional study in Norway, Sweden, and Denmark

Abstract Objectives The primary objective of this study was to explore whether general practitioners (GPs) in Norway, Sweden, and Denmark make similar or different decisions regarding sick leave for patients with severe subjective health complaints (SHC). The secondary objective was to investigate if patient diagnoses, the reasons attributed for patient complaints, and GP demographics could explain variations in sick leave decisions. Design A cross-sectional study. Method Video vignettes of GP consultations with nine different patients. Subjects 126 GPs in Norway, Sweden, and Denmark. Setting Primary care in Norway, Sweden, and Denmark. Main outcome measure Sick leave decisions made by GPs. Results “Psychological” diagnoses in Sweden were related to lower odds ratio (OR) of granting sick leave than in Norway (OR = 0.07; 95% CI = 0.01–0.83) Assessments of patient health, the risk of deterioration, and their ability to work predicted sick leave decisions. Specialists in general medicine grant significantly fewer sick leaves than non-specialists. Conclusion Sick-leave decisions made by GPs in the three countries were relatively similar. However, Swedish GPs were more reluctant to grant sick leave for patients with “psychological” diagnoses. Assessments regarding health-related factors were more important than diagnoses in sick-leave decisions. Specialist training may be of importance for sick-leave decisions. PMID:24164371

Plants growing in small fragmented populations under stressful environmental conditions may have reduced sexual reproduction. This can cause low gene flow between populations and eventually extinction. Here we report on a pollination experiment with Sorbus torminalis, a rare fleshy-fruited tree with a submediterranean distribution in Europe. At the northern limit of its range in SE-Denmark two relatively small and isolated populations were studied for effects of seven pollination treatments on fruit production and on the timing of fruit abortion. There was evidence that lack of pollination and spontaneous self-pollination caused particularly high fruit abortion, which indicates that apomixis is unlikely and spontaneous self-pollination not efficient. Fruit abortion was delayed after hand pollination, which suggests limitation by pollen quantity. Self-pollination caused earlier abortion than experimental cross-pollination within or between populations indicating inbreeding depression. There was no evidence for outbreeding depression as measured by fruit abortion. We conclude that generative reproduction of S. torminalis is reduced on its northern distribution limit and that it might be negatively affected by pollen limitation and inbreeding effects, which have not been compensated for by increased self-compatibility or apomixis.

The large population of feral cats in Denmark may potentially transmit pathogens to household cats and zoonotic parasites to humans. A total of 99 euthanized cats; feral cats (n=92) and household cats with outdoor access (n=7), were collected from March to May 2014 from the Zealand region, Denmark. The sedimentation and counting technique (SCT) was used to isolate helminths and coproscopy was done by concentration McMaster technique (c-McMaster). Overall, 90.1% of the cats were infected and a total of 10 species were recorded by SCT: 5 nematode species: Toxocara cati (84.8%), Ollulanus tricuspis (13.1%), Aonchotheca putorii (7.1%), Paersonema spp. (3.0%), Strongyloides spp. (1.0%); 3 cestodes: Hydatigera taeniaeformis (36.4%), Mesocestoides sp. (3.0%), Dipylidium caninum (1.0%); and 2 trematodes: Cryptocotyle spp. (5.1%) and Pseudamphistomum truncatum (1.0%). O. tricuspis was the second most common gastrointestinal nematode of cats but had the highest intensity of infection. For T. cati, prevalence and worm burden were significantly higher in feral than household cats. No juvenile cats were infected with H. taeniaeformis, and age thus had a significant effect on prevalence and worm burdens of this species. Rural cats had a higher prevalence and worm burden of A. putorii than urban cats. By c-McMaster, ascarid, capillarid, strongylid or taeniid type eggs were found in 77.9% of the cats while Cystoisospora felis was found in 2.1%. The sensitivity of the c-McMaster was 82.5% for T. cati but 26.5% for taeniid eggs, using the SCT as gold standard. A positive correlation between faecal egg counts and worm burdens was seen for T. cati, but not for taeniid eggs (assumed to be H. taeniaeformis). Coprological examination also detected the eggs of extraintestinal Capillariidae species including Eucoleus aerophilus and Eucoleus boehmi, but further necropsy studies are needed to confirm these findings.

European beech (Fagus sylvatica L., hereafter beech), one of the major native tree species in Europe, is known to be drought sensitive. Thus, the identification of critical thresholds of drought impact intensity and duration are of high interest for assessing the adaptive potential of European beech to climate change in its native range. In a common garden experiment with one-year-old seedlings originating from central and marginal origins in six European countries (Denmark, Germany, France, Romania, Bosnia-Herzegovina, and Spain), we applied extreme drought stress and observed desiccation and mortality processes among the different populations and related them to plant water status (predawn water potential, ΨPD) and soil hydraulic traits. For the lethal drought assessment, we used a critical threshold of soil water availability that is reached when 50% mortality in seedling populations occurs (LD50SWA). We found significant population differences in LD50SWA (10.5-17.8%), and mortality dynamics that suggest a genetic difference in drought resistance between populations. The LD50SWA values correlate significantly with the mean growing season precipitation at population origins, but not with the geographic margins of beech range. Thus, beech range marginality may be more due to climatic conditions than to geographic range. The outcome of this study suggests the genetic variation has a major influence on the varying adaptive potential of the investigated populations.

A recent study reported a large increase in the number of meniscal procedures from 2000 to 2011 in Denmark. We examined the nation-wide distribution of meniscal procedures performed in the private and public sector in Denmark since different incentives may be present and the use of these procedures may differ from region to region. We included data on all patients who underwent an arthroscopic meniscal procedure performed in the public or private sector in Denmark. Data were retrieved from the Danish National Patient Register on patients who underwent arthroscopic meniscus surgery as a primary or secondary procedure in the years 2000 to 2011. Hospital identification codes enabled linkage of performed procedures to specific hospitals. Yearly incidence of meniscal procedures per 100,000 inhabitants was calculated with 95% CIs for public and private procedures for each region. Incidence of meniscal procedures increased at private and at public hospitals. The private sector accounted for the largest relative and absolute increase, rising from an incidence of 1 in 2000 to 98 in 2011. In 2011, the incidence of meniscal procedures was three times higher in the Capital Region than in Region Zealand. Our study identified a large increase in the use of meniscal procedures in the public and private sector in Denmark. The increase was particularly conspicuous in the private sector as its proportion of procedures performed increased from 1% to 32%. Substantial regional differences were present in the incidence and trend over time of meniscal procedures. Published by the BMJ Publishing Group Limited.

Although increased risk for schizophrenia among immigrants is well established, knowledge of the broader spectrum of psychiatric disorders associated with a foreign migration background is lacking. To examine the full range of psychiatric disorders associated with any type of foreign migration background among persons residing in Denmark, including foreign-born adoptees, first- and second-generation immigrants, native Danes with a history of foreign residence, and persons born abroad to Danish expatriates. Danish population-based cohort study. Persons were followed up from their 10th birthday for the development of mental disorders based on outpatient and inpatient data. All persons born between January 1, 1971, and December 31, 2000 (N = 1 859 419) residing in Denmark by their 10th birthday with follow-up data to December 31, 2010. Incidence rate ratios (IRRs) and cumulative incidences for psychiatric outcomes. All categories of foreign migration background, except persons born abroad to Danish expatriates, were associated with increased risk for at least 1 psychiatric disorder. Foreign-born adoptees had increased IRRs for all psychiatric disorders and had the highest IRRs for these disorders compared with other foreign migration categories. First- and second-generation immigrants having 2 foreign-born parents had significantly increased IRRs for schizophrenia and schizophrenia spectrum disorders and had similar risk magnitudes. Second-generation immigrants having 1 foreign-born parent had significantly increased IRRs for all psychiatric disorders. Native Danes with a history of foreign residence had increased IRRs for bipolar affective disorder, affective disorders, personality disorders, and schizophrenia spectrum disorders. The extent to which a background of foreign migration confers an increased risk for the broad spectrum of psychiatric disorders varies according to parental origin, with greatest risks for foreign-born adoptees. The spectrum of psychiatric disorders showed greater variation within the second-generation immigrant group than between first-generation vs second-generation immigrants, and the spectrum differed according to whether individuals had 1 or 2 foreign-born parents.

Stress is a growing public health problem, but there are only a few studies with national representative samples on the occurrence of stress. The aim of this study was to assess the level of stress, measured by the Perceived Stress Scale, in Denmark, and to identify and characterize the group with high levels of stress by factors measured at both the individual and neighbourhood levels in a national representative sample of the Danish population. The 10,022 participants in the National Health Interview Survey 2005 were asked about perceived stress and individual factors in a cross-sectional design. Information on neighbourhood factors was derived from a national registry. Data were analysed by means of logistic regression models. Low education, heavy smoking, physical inactivity, lack of social network and poor working conditions were associated with perceived stress. For women, living in a neighbourhood with low average education, and for men, living in a neighbourhood with a high rate of crime and a low degree of ethnic diversity, were associated with higher perceived stress. Perceived stress was also related to indicators of morbidity. The group with high perceived stress is characterized by individual and neighbourhood factors with negative impacts on quality of life and risk of illness. This knowledge can guide future stress prevention efforts. Additionally, the results suggest a negative social component where perceived stress, unhealthy lifestyle and low social status are accumulated, and perceived stress might be used as a measure to identify groups characterized by accumulation of risk factors.

Objective To examine associations in a preterm population between rs9883204 in ADCY5 and rs900400 near LEKR1 and CCNL1 with birth weight. Both markers were associated with birth weight in a term population in a recent genome-wide association (GWA) study by Freathy et al. Study design A meta-analysis of mother and infant samples was performed for associations of rs900400 and rs9883204 with birth weight in 393 families from the U.S., 265 families from Argentina and 735 mother-infant pairs from Denmark. Z scores adjusted for infant sex and gestational age were generated for each population separately and regressed on allele counts. Association evidence was combined across sites by inverse-variance weighted meta-analysis. Results Each additional C allele of rs900400 (LEKR1/CCNL1) in infants was marginally associated with a 0.069 standard deviation (SD) lower birth weight (95% CI = −0.159 – 0.022, P = 0.068). This result was slightly more pronounced after adjusting for smoking (P = 0.036). There were no significant associations identified with rs9883204 or in maternal samples. Conclusions These results indicate the potential importance of this marker on birth weight irrespective of gestational age. PMID:21885063

2004-01-01

A genetic study of the European tree frog, Hyla arborea, in Denmark was undertaken to examine the population structure on mainland Jutland and the island of Lolland after a period of reduction in suitable habitat and population sizes. The two regions have experienced the same rate of habitat loss but fragmentation has been more severe on Lolland. Genetic variation based on 12 polymorphic DNA microsatellites was analysed in 494 tree frogs sampled from two ponds in Jutland and 10 ponds on Lolland. A significant overall deviation from Hardy-Weinberg expectations could be attributed to three ponds, all on Lolland. This was most probably caused by an inbreeding effect reducing fitness, which was supported by the observed significant negative correlation between larva survival and mean F(IS) value and mean individual inbreeding coefficient. A significant reduction in genetic variation (bottleneck) was detected in most of the ponds on Lolland. Population-structure analysis suggested the existence of at least 11 genetically different populations, corresponding to most of the sampled population units. The results indicated that the populations were unique genetic units and could be used to illustrate the migration pattern between newly established ponds arisen either by natural colonization of tree frogs or by artificial introduction. A high degree of pond fidelity in the tree frogs was suggested. A severe fragmentation process reducing population size and fitness within some of the populations probably caused the significant reduction in genetic variation of tree frog populations on Lolland.

One goal of the study was to identify "new" statistically independent risk factors for treatment-demanding retinopathy of prematurity (ROP). Another goal was to evaluate whether any new risk factors could explain the increase in the incidence of treatment-demanding ROP over time in Denmark. A retrospective, register-based cohort study. The study included premature infants (n = 6490) born in Denmark from 1997 to 2008. The study sample and the 31 candidate risk factors were identified in 3 national registers. Data were linked through a unique civil registration number. Each of the 31 candidate risk factors were evaluated in univariate analyses, while adjusted for known risk factors (i.e., gestational age [GA] at delivery, small for gestational age [SGA], multiple births, and male sex). Significant outcomes were analyzed thereafter in a backward selection multiple logistic regression model. Treatment-demanding ROP and its associations to candidate risk factors. Mechanical ventilation (odds ratio [OR], 2.84; 95% confidence interval [CI], 1.99-4.08; P < 0.01) and blood transfusion (OR, 1.97; 95% CI, 1.20-3.14; P = 0.01) were the only new statistically independent risk factors, in addition to GA at delivery, SGA, multiple births, and male sex. Modification in these prognostic factors for ROP did not cause an increase in treatment-demanding ROP. In a large study population, blood transfusion and mechanical ventilation were the only new statistically independent risk factors to predict the development of treatment-demanding ROP. Modification in the neonatal treatment with mechanical ventilation or blood transfusion did not cause the observed increase in the incidence of preterm infants with treatment-demanding ROP during a recent birth period (2003-2008).

2017-04-20

Information and communication sources in the healthcare sector are replaced with new eHealth technologies. This has led to problems arising from the lack of awareness of the importance of end-user involvement in eHealth development and of the difficulties caused by using traditional summative evaluation methods. The Constructive eHealth evaluation method (CeHEM) provides a solution to these problems by offering an evaluation framework for supporting and facilitating end-user involvement during all phases of eHealth development. The aim of this paper is to support this process by sharing experiences of the eHealth evaluation method used in the introduction of electronic health records (EHR) in the North Denmark Region of Denmark. It is the first time the fully developed method and the experiences on using the CeHEM in all five phases of a full lifecycle framework is presented. A case study evaluation of the EHR development process in the North Denmark Region was conducted from 2004 to 2010. The population consisted of clinicians, IT professionals, administrators, and vendors. The study involved 4 hospitals in the region. Data were collected using questionnaires, observations, interviews, and insight gathered from relevant documents. The evaluation showed a need for a) Early involvement of clinicians, b) The best possible representation of clinicians, and c) Workload reduction for those involved. The consequences of not providing this were a lack of ownership of decisions and negative attitudes towards the clinical benefits related to these decisions. Further, the result disclosed that by following the above recommendations, and by providing feedback to the 4 actor groups, the physicians' involvement was improved. As a result they took ownership of decisions and gained a positive attitude to the clinical benefits. The CeHEM has proven successful in formative evaluation of EHR development and can point at important issues that need to be taken care of by management. The method provides a framework that takes care of feedback and learning during eHealth development. It can thus support successful eHealth development in a broader context while building on a well-known success factor: end-user involvement in eHealth development.

The use of a validated screening questionnaire to identify individuals with chronic leg ulcers allows large-scale population-based studies to be conducted that measure and monitor the prevalence of the disease. The aim of this study was to design and validate such a screening questionnaire to identify patients with chronic leg ulcers. A simple 3-item questionnaire was developed at the Department of Dermatology, University Hospital of Zealand, Denmark. In total, 90 patients attending the department's outpatient clinic for dermatological diseases and chronic wounds were included in this study. All included participants completed the questionnaire and were subsequently examined by dermatologists. We found that the constructed 3-item questionnaire in this study had a sensitivity and specificity of 95% and 93% and a positive predictive value and negative predictive value of 78% and 95%, respectively. Moreover, we found that the use of the 3-item questionnaire, as compared with a single question, in which the participants were asked whether they currently have a leg ulcer, resulted in significantly higher positive predictive value (+11.6%, P = .035) and specificity (+5.6%, P = .046) of the diagnostic test. Future studies are merited to investigate the diagnostic accuracy of the questionnaire in other populations and settings.

Denmark has experienced an increase in melanoma incidence since the 1960s. Exposure to ultraviolet radiation is the main preventable cause of this cancer. We examined current travel to, and sun-related behaviour of Danes at, sunny destinations in relation to their risk for sunburn. A population-based sample of 11,158 respondents aged 15-59 years completed three questionnaires in 2007-2009 that included items on exposure to ultraviolet radiation. Using logistic regression analysis we examined the relations between sunny vacations, sun-related behaviour, demographic factors and risk for sunburn. During 2007-2009, 44.8-45.8% of the respondents travelled to a sunny destination at least once a year; 24% became sunburnt, and 69% tanned intentionally. The odds ratio for sunburn in general for people who went on a sunny vacation as compared with those who did not was 1.6 (1.5-1.7). Sunscreen use (1.9; 1.4-2.6) and intentional tanning (3.4; 2.8-4.1) were positively associated with sunburn on vacation. Taking a vacation in a sunny place is a risk factor for sunburn, especially for young people. The recommendation for sunscreen use should be re-evaluated, as intention to tan is the most important factor in sunburn on vacation and should be targeted more strategically.

Climate analogues, also denoted Space-For-Time, may be used to identify regions where the present climatic conditions resemble conditions of a past or future state of another location or region based on robust climate variable statistics in combination with projections of how these statistics change over time. The study focuses on assessing climate analogues for Denmark based on current climate data set (E-OBS) observations as well as the ENSEMBLES database of future climates with the aim of projecting future precipitation extremes. The local present precipitation extremes are assessed by means of intensity-duration-frequency curves for urban drainage design for the relevant locations being France, the Netherlands, Belgium, Germany, the United Kingdom, and Denmark. Based on this approach projected increases of extreme precipitation by 2100 of 9 and 21% are expected for 2 and 10 year return periods, respectively. The results should be interpreted with caution as the best region to represent future conditions for Denmark is the coastal areas of Northern France, for which only little information is available with respect to present precipitation extremes.

Mapping the lack of public initiative against female genital mutilation in Denmark.

Female genital mutilation (FGM) is a harmful practice prevalent in 35 countries, mainly in Africa, as well as in some Middle Eastern countries and a few Asian countries. FGM comprises all procedures that involve partial or complete resection of, or other injury to, external female genitalia for non-medical reasons. The practice of FGM has spread to Western countries due to migration. The European Institute for Gender Equality recommend that FGM be combatted by nationally coordinated efforts through implementation of national action plans, guidelines for professionals as well as comprehensive research in the field. FGM was outlawed in Denmark 2003, but no national actions plan has been implemented. Instead, the task of combatting FGM is currently under the responsibility of local governments in the form of the 98 municipalities. The aim of this study is to investigate the Danish municipalities' efforts to prevent FGM on the local level, and whether these initiatives are in accordance with international recommendations and standards. All 98 Danish municipalities were invited to respond to a questionnaire regarding FGM in their respective municipalities. The inclusion process and questionnaire was designed after a pilot study, which included 29 municipalities. The questionnaire consisted of four overall areas of focus: "action plan", "registration", "information material" and "preventive initiatives". Demographic data were gathered from the 2017 census by Statistics Denmark. Risk countries were defined as countries with a tradition for FGM, identified from the 2016 UNICEF definition. A total of 67 municipalities participated in the study. At the time of census, 1.8% of the Danish population was immigrants with origins in risk countries. A total of 10.4% of the responding municipalities indicated to have implemented a specific action plan against FGM. A total of 7,5% had implemented specific preventive initiatives against FGM. Registration of reported FGM cases were indicated to be performed in 73.1% of the responding municipalities; however, only 17.9% stated to perform registration of FGM specifically as such, and not as general child abuse. Our study shows that the current situation of FGM registration and prevention being under local administrative responsibility in the 98 Danish municipalities has led to a severe lack of coordinated public initiative against FGM.

Denmark was the first country in the world to implement a national, free-for-all offer of prenatal screening for Down syndrome to all pregnant women. It has a high uptake (>90%) compared to other countries. Thus, Denmark offers an interesting case for investigating the consequences of implementing comprehensive, national prenatal screening guidelines. The aim of this study was to describe the historical developments in invasive procedures, pre-/postnatal diagnoses of Down syndrome and Down syndrome live births in the period 1973-2016 in Denmark. Data on invasive procedures, pre- and postnatal Down syndrome diagnoses were retrieved from the Danish Cytogenetic Central Registry. From 1973 to 1993, screening based on maternal age and high-risk indications resulted in a constant increase in invasive procedures. After the introduction of the triple test in 1994, invasive procedures decreased for the first time in 20 years. Following the introduction of an offer of combined screening to all pregnant women in 2004, the number of invasive procedures decreased markedly, while there was a concurrent increase in prenatal diagnoses of Down syndrome. Additionally, the number of Down syndrome live births decreased suddenly and significantly, but subsequently stabilized at 23-35 annual live births. Of these, the majority were diagnosed postnatally. Though prenatal screening technologies constantly improve, it was the introduction of and adherence to national guidelines that resulted in marked shifts in screening procedures and outcome in Denmark. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Background In the Nordic countries, substantial policy and intervention efforts have been made to increase adolescents' consumption of fruit and vegetables and to reduce their intake of sweets and soft drinks. Some initiatives have been formulated in a Nordic collaboration and implemented at national level. In recent years, social inequalities in food habits have been attracted particular governmental interest and several initiatives addressing the socioeconomic gradient in food habits have been highlighted. However, few internationally published studies have evaluated how trends in adolescents' food habits develop in the context of Nordic nutrition policy, or have compared differences between the Nordic countries. Methods The study was based on Danish, Finnish, Norwegian and Swedish cross-sectional data from the international Health Behaviour in School-Aged Children (HBSC) study, collected via three nationally representative and comparable questionnaire surveys in 2001/2002, 2005/2006 and 2009/2010. Food habits were identified by students' consumption of fruit, vegetables, sweets and sugar sweetened soft drink. Socioeconomic status (SES) was measured with the Family Affluence Scale (FAS). Multilevel logistic regression was used to analyze the data. Results Trends in fruit consumption developed differently across countries, characterized by an increase in Denmark and Norway and more stable trends in Sweden and Finland. Vegetable consumption increased particularly in Denmark and to a lesser extent in Norway, whereas Sweden and Finland displayed stable trends. Decreased trends were observed for sweet and soft drink consumption and were similar in Norway, Sweden and Finland. Sweet consumption decreased across all survey years, whereas soft drink consumption decreased between 2001/2002–2005/2006 and was stable thereafter. Denmark displayed an increase between 2001/2002–2005/2006 followed by a similar decrease between 2005/2006–2009/2010 for both sweet and soft drink consumption. Socioeconomic inequalities in fruit and vegetable consumption were observed in all countries, with no cross-country differences, and no changes over time. Small but not significant cross-country variation was identified for SES inequalities in sweet consumption. Reduced SES inequalities were observed in Sweden between 2005/2006 and 2009/2010. SES was not associated with soft drink consumption in this study population, with the exception of Denmark for the survey year 2009/2010. Conclusion Different trends resulted in increased country differences in food habits during the time of observations. In survey year 2009/2010, Danish students reported a higher intake of fruit and vegetable consumption than their counterparts in the other Nordic countries. Finnish students reported the lowest frequency of sweets and soft drink consumption. Despite the positive dietary trends documented in the present study, the majority of Nordic adolescents are far from meeting national dietary recommendations. Our findings underline the need for more comprehensive initiatives targeting young people's food habits as well as a more deliberate and focused action to close gaps in social inequalities that affect food choices.

In the Nordic countries, substantial policy and intervention efforts have been made to increase adolescents' consumption of fruit and vegetables and to reduce their intake of sweets and soft drinks. Some initiatives have been formulated in a Nordic collaboration and implemented at national level. In recent years, social inequalities in food habits have been attracted particular governmental interest and several initiatives addressing the socioeconomic gradient in food habits have been highlighted. However, few internationally published studies have evaluated how trends in adolescents' food habits develop in the context of Nordic nutrition policy, or have compared differences between the Nordic countries.

Inadequate parenting is an important public health problem with possible severe and long-term consequences related to child development. We have solid theoretical and political arguments in favor of efforts enhancing the quality of the early family environment in the population at large. However, little is known about effect of universal approaches to parenting support during the transition to parenthood. This protocol describes an experimental evaluation of group based parenting support, the Family Startup Program (FSP), currently implemented large scale in Denmark. Participants will be approximately 2500 pregnant women and partners. Inclusion criteria are parental age above 18 and the mother expecting first child. Families are recruited when attending routine pregnancy scans provided as a part of the publicly available prenatal care program at Aarhus University Hospital, Skejby. Families are randomized within four geographically defined strata to one of two conditions a) participation in FSP or b) Treatment As Usual (TAU). FSP aims to prepare new families for their roles as parents and enhance parental access to informal sources of support, i.e. social network and community resources. The program consists of twelve group sessions, with nine families in each group, continuing from pregnancy until the child is 15 months old. TAU is the publicly available pre- and postnatal care available to families in both conditions. Analyses will employ survey data, administrative data from health visitors, and administrative register based data from Statistics Denmark. All data sources will be linked via the unique Danish Civil Registration Register (CPR) identifier. Data will be obtained at four time points, during pregnancy, when the child is nine months, 18 months and seven years. The primary study outcome is measured by the Parenting Sense of Competence scale (PSOC) J Clin Child Psychol 18:167-75, 1989. Other outcomes include parenting and couple relationship quality, utility of primary sector service and child physical health, socio-emotional and cognitive development. The protocol describes an ambitious experimental evaluation of a universal group-based parenting support program; an evaluation that has not yet been made either in Denmark or internationally.

A few studies have indicated a positive association between consumption of alcohol and allergic sensitization in age and socioeconomically heterogeneous populations. To investigate the association between consumption of alcohol and allergic sensitization in a young homogenous population of high social class (a group with a suspected high prevalence of sensitization). A total of 1,668 students aged 18 to 35 years recruited from universities in Copenhagen, Denmark, underwent skin prick testing (SPT) in October or November 2002 and completed a questionnaire about respiratory disease and lifestyle habits, including alcohol consumption. SPT positivity was defined as a positive reaction (> or =3 mm) against at least 1 of 10 common inhalant allergens. Before and after adjustment for sex, age, smoking, atopic predisposition, and pet keeping, no significant association was found between alcohol consumption (including type of beverage) and SPT positivity. Increasing alcohol consumption was significantly negatively associated with asthma symptoms and hay fever symptoms. Alcohol consumption does not favor SPT positivity, but cumulated effects were not addressed in the present study. Individuals with asthma or hay fever symptoms seem to reduce alcohol intake (a healthy drinkers' effect).

We sought to examine whether neighborhood deprivation is associated with participation in a large population-based health check. Such analyses will help answer the question whether health checks, which are designed to meet the needs of residents in deprived neighborhoods, may increase participation and prove to be more effective in preventing disease. In Europe, no study has previously looked at the association between neighborhood deprivation and participation in a population-based health check. The study population comprised 12,768 persons invited for a health check including screening for ischemic heart disease and lifestyle counseling. The study population was randomly drawn from a population of 179,097 persons living in 73 neighborhoods in Denmark. Data on neighborhood deprivation (percentage with basic education, with low income and not in work) and individual socioeconomic position were retrieved from national administrative registers. Multilevel regression analyses with log links and binary distributions were conducted to obtain relative risks, intraclass correlation coefficients and proportional change in variance. Large differences between neighborhoods existed in both deprivation levels and neighborhood health check participation rate (mean 53%; range 35-84%). In multilevel analyses adjusted for age and sex, higher levels of all three indicators of neighborhood deprivation and a deprivation score were associated with lower participation in a dose-response fashion. Persons living in the most deprived neighborhoods had up to 37% decreased probability of participating compared to those living in the least deprived neighborhoods. Inclusion of individual socioeconomic position in the model attenuated the neighborhood deprivation coefficients, but all except for income deprivation remained statistically significant. Neighborhood deprivation was associated with participation in a population-based health check in a dose-response manner, in which increasing neighborhood deprivation was associated with decreasing participation. This suggests the need to develop preventive health checks tailored to deprived neighborhoods.

The risk-stratified osteoporosis strategy evaluation study (ROSE) is a randomized prospective population-based study investigating the effectiveness of a two-step screening program for osteoporosis in women. This paper reports the study design and baseline characteristics of the study population. 35,000 women aged 65-80 years were selected at random from the population in the Region of Southern Denmark and-before inclusion-randomized to either a screening group or a control group. As first step, a self-administered questionnaire regarding risk factors for osteoporosis based on FRAX(®) was issued to both groups. As second step, subjects in the screening group with a 10-year probability of major osteoporotic fractures ≥15% were offered a DXA scan. Patients diagnosed with osteoporosis from the DXA scan were advised to see their GP and discuss pharmaceutical treatment according to Danish National guidelines. The primary outcome is incident clinical fractures as evaluated through annual follow-up using the Danish National Patient Registry. The secondary outcomes are cost-effectiveness, participation rate, and patient preferences. 20,904 (60%) women participated and included in the baseline analyses (10,411 in screening and 10,949 in control group). The mean age was 71 years. As expected by randomization, the screening and control groups had similar baseline characteristics. Screening for osteoporosis is at present not evidence based according to the WHO screening criteria. The ROSE study is expected to provide knowledge of the effectiveness of a screening strategy that may be implemented in health care systems to prevent fractures.

Over the past three decades, public attitudes to organ donation have been a subject of numerous studies focusing on donor motivation. Here, we present a fresh approach. We suggest focusing on public acceptability instead of motivation. The point is to understand public attitudes well enough to avoid risking public support for organ transplantation. We conducted the study in Denmark because there have been significant developments in public attitudes to organ donation in this country. In the 1990s, Denmark was a country with very low public support for organ donation and Denmark was the last country in Europe to introduce brain death as a legal criterion of death, whereas today Eurobarometer surveys rate Denmark as one of the European countries with the highest support for deceased organ donation from brain dead donors. We conducted a telephone survey in Denmark (N = 1195). A questionnaire was developed on the basis of preceding qualitative studies and pilot testing and included reuse of one item from earlier surveys to facilitate historical comparison. The analysis of the data was carried out using IBM SPSS Statistics 22 and focused on descriptive statistics. A clear majority of 91.9 % are positive or very positive towards organ donation; 85.8 % like the idea of their body being used after their death, 85.0 % is willing to donate their own organs, 82.1 % to donate their tissue and only 2.3 % find that too much has been done to promote organ donation. There is limited support for monetary incentives for organ donation (5.8 %) and presumed consent (30.4 %), while a majority (63.9 %) supports making it mandatory to register a personal decision. Religious self-identification has limited impact on attitudes. We can identify a shift over the past three decades from marked opposition to organ transplantation to strong support as well as a pattern in the contemporary public attitudes, which can help explain what is central to public acceptability: self-determination. Policies fostering choice are met with a majority of positive attitudes, while presumed consent and monetary incentives are met with more negative attitudes. Our approach calls for comparative studies in other countries to generate a better overall understanding of the conditions of acceptability, which need to be in place to ensure the long-term social robustness of organ donation and thereby safeguard this important medical technology.

Survivors of childhood cancer are at increased risk for a wide range of late effects. However, no large population-based studies have included the whole range of somatic diagnoses including subgroup diagnoses and all main types of childhood cancers. Therefore, we aimed to provide the most detailed overview of the long-term risk of hospitalisation in survivors of childhood cancer. From the national cancer registers of Denmark, Finland, Iceland, and Sweden, we identified 21,297 5-year survivors of childhood cancer diagnosed with cancer before the age of 20 years in the periods 1943-2008 in Denmark, 1971-2008 in Finland, 1955-2008 in Iceland, and 1958-2008 in Sweden. We randomly selected 152,231 population comparison individuals matched by age, sex, year, and country (or municipality in Sweden) from the national population registers. Using a cohort design, study participants were followed in the national hospital registers in Denmark, 1977-2010; Finland, 1975-2012; Iceland, 1999-2008; and Sweden, 1968-2009. Disease-specific hospitalisation rates in survivors and comparison individuals were used to calculate survivors' standardised hospitalisation rate ratios (RRs), absolute excess risks (AERs), and standardised bed day ratios (SBDRs) based on length of stay in hospital. We adjusted for sex, age, and year by indirect standardisation. During 336,554 person-years of follow-up (mean: 16 years; range: 0-42 years), childhood cancer survivors experienced 21,325 first hospitalisations for diseases in one or more of 120 disease categories (cancer recurrence not included), when 10,999 were expected, yielding an overall RR of 1.94 (95% confidence interval [95% CI] 1.91-1.97). The AER was 3,068 (2,980-3,156) per 100,000 person-years, meaning that for each additional year of follow-up, an average of 3 of 100 survivors were hospitalised for a new excess disease beyond the background rates. Approximately 50% of the excess hospitalisations were for diseases of the nervous system (19.1% of all excess hospitalisations), endocrine system (11.1%), digestive organs (10.5%), and respiratory system (10.0%). Survivors of all types of childhood cancer were at increased, persistent risk for subsequent hospitalisation, the highest risks being those of survivors of neuroblastoma (RR: 2.6 [2.4-2.8]; n = 876), hepatic tumours (RR: 2.5 [2.0-3.1]; n = 92), central nervous system tumours (RR: 2.4 [2.3-2.5]; n = 6,175), and Hodgkin lymphoma (RR: 2.4 [2.3-2.5]; n = 2,027). Survivors spent on average five times as many days in hospital as comparison individuals (SBDR: 4.96 [4.94-4.98]; n = 422,218). The analyses of bed days in hospital included new primary cancers and recurrences. Of the total 422,218 days survivors spent in hospital, 47% (197,596 bed days) were for new primary cancers and recurrences. Our study is likely to underestimate the absolute overall disease burden experienced by survivors, as less severe late effects are missed if they are treated sufficiently in the outpatient setting or in the primary health care system. Childhood cancer survivors were at increased long-term risk for diseases requiring inpatient treatment even decades after their initial cancer. Health care providers who do not work in the area of late effects, especially those in primary health care, should be aware of this highly challenged group of patients in order to avoid or postpone hospitalisations by prevention, early detection, and appropriate treatments.

We investigated whether the risk of cerebral palsy (CP) in the child varies by parents' socioeconomic status, in Denmark and Norway. We included almost 1.3 million children born in Demark during 1981-2007 and 2.4 million children born in Norway during 1967-2007, registered in the Medical Birth registries. Data on births were linked to Statistics Denmark and Norway to retrieve information on parents' education and relationship status and, in Denmark, also income. CP diagnoses were obtained from linkage with national registries. We used multivariate log-binominal regression models to estimate relative risk (RR) of CP according to parental socioeconomic status. There was a strong trend of decreasing risk of CP with additional education of both the mother and the father. These trends were nearly identical for the two parents, with a one-third reduction in risk for those with the highest education compared with parents with the lowest education. When both parents had high education, risk of CP was further reduced (RR 0.58, 0.53-0.63). Women with partners had a reduction in risk (RR 0.79, 0.74-0.85) compared with single mothers overall. Risk patterns were stable over time, across countries and within spastic bilateral and unilateral CP. Household income was not associated with risk of CP. Risk of CP in two Scandinavian countries was lower among educated parents and mothers with a partner, but unrelated to income. Factors underlying this stable association with education are unknown, but could include differences in potentially modifiable lifestyle factors and health behaviours.

To estimate the prevalence of time pressure experienced by parents in the Nordic countries and examine potential gender disparities as well as associations to parents' family and/or living conditions. 5949 parents of children aged 2-17 years from Denmark, Finland, Norway and Sweden, participating in the 2011 version of the NordChild study, reported their experience of time pressure when keeping up with duties of everyday life. A postal questionnaire addressed to the most active caretaker of the child, was used for data gathering and logistic regression analysis applied. The mother was regarded as the primary caregiver in 83.9% of the cases. Of the mothers, 14.2% reported that they experienced time pressure "most often", 54.7 % reported "sometimes" and 31.1 % reported they did "not" experience time pressure at all. Time pressure was experienced by 22.2 % of mothers in Sweden, 18.4% in Finland, 13.7% in Norway and 3.9% in Denmark, and could be associated to lack of support, high educational level, financial stress, young child age and working overtime. The mother is regarded as the child's primary caregiver among the vast majority of families in spite of living in societies with gender-equal family policies. The results indicate that time pressure is embedded in everyday life of mainly highly-educated mothers and those experiencing financial stress and/or lack of social support. No conclusion could be made about time pressure from the "normbreaking" fathers participating in the study, but associations were found to financial stress and lack of support.

Denmark and several other countries experienced the first epidemic of methicillin-resistant Staphylococcus aureus (MRSA) during the period 1965-75, which was caused by multiresistant isolates of phage complex 83A. In Denmark these MRSA isolates disappeared almost completely, being replaced by other phage types, predominantly only penicillin resistant. We investigated whether isolates of this epidemic were associated with a fitness cost, and we employed a mathematical model to ask whether these fitness costs could have led to the observed reduction in frequency. Bacteraemia isolates of S. aureus from Denmark have been stored since 1957. We chose 40 S. aureus isolates belonging to phage complex 83A, clonal complex 8 based on spa type, ranging in time of isolation from 1957 to 1980 and with various antibiograms, including both methicillin-resistant and -susceptible isolates. The relative fitness of each isolate was determined in a growth competition assay with a reference isolate. Significant fitness costs of 2%-15% were determined for the MRSA isolates studied. There was a significant negative correlation between number of antibiotic resistances and relative fitness. Multiple regression analysis found significantly independent negative correlations between fitness and the presence of mecA or streptomycin resistance. Mathematical modelling confirmed that fitness costs of the magnitude carried by these isolates could result in the disappearance of MRSA prevalence during a time span similar to that seen in Denmark. We propose a significant fitness cost of resistance as the main bacteriological explanation for the disappearance of the multiresistant complex 83A MRSA in Denmark following a reduction in antibiotic usage.

The use of artificial joint implants has risen greatly over the past years. However, few investigations of the cancer risk associated with implants have been performed. We investigated cancer risk in patients with finger and hand joint and temporo-mandibular (TMJ) joint implants. A nationwide cohort in Denmark of patients with finger and hand joint prostheses (n = 858) or TMJ implants (n = 389) was followed from January 1, 1977, to December 31, 1995, to evaluate any potential cancer risks subsequent to receiving these implants. Standardized incidence ratios (SIRs) for all cancers were 1.0 (95% CI = 0.8-1.2) for the finger and hand joint cohort and 1.1 (95% CI = 0.8-1.7) for the TMJ cohort. A significant risk for non-Hodgkin's lymphoma was found in the finger and hand joint cohort (SIR = 3.8, 95% CI = 1.5-7.8). When the finger and hand joint cohort was stratified by diagnosis of rheumatoid arthritis, the excess risk was seen only in the group with rheumatoid arthritis. This is consistent with past studies, which have found an association between rheumatoid arthritis and non-Hodgkin's lymphoma. Our results provide evidence that the cancer risk for patients with finger and hand joint prostheses and TMJ implants is similar to that for the general population.

Denmark is widely regarded as a leading country in terms of eHealth integration and healthcare delivery services. The push for eHealth adoption over that past 20 years in the Danish health sector has led to the deployment of multiple eHealth technologies. However, in reality the Danish healthcare suffers from eHealth system fragmentation which has led to eHealth's inability to reach full potential in delivering quality healthcare service. This paper will presents a case study of the current state of eHealth in the Danish healthcare system and discuss the current challenges the country is facing today.

To prevent goiter and nodular hyperthyroidism, iodine fortification (IF) of salt was introduced in Denmark in 1998. We prospectively registered all new cases of overt hyperthyroidism in two areas of Denmark before and for the first 6 yr after iodine fortification. We used a computer-based register of all new cases of hyperthyroidism in two population subcohorts with moderate iodine deficiency (Aalborg, n = 310,124) and mild iodine deficiency (Copenhagen, n = 225,707), respectively. Data were obtained 1) before IF (1997-1998); 2) during voluntary IF (1999-2000); 3) during the early (2001-2002) period of mandatory IF; and 4) during the late (2003-2004) period with mandatory IF. The overall incidence rate of hyperthyroidism increased [baseline, 102.8/100,000/year; voluntary IF, 122.8; early mandatory IF, 140.7; late mandatory IF, 138.7 (P for trend <0.001)]. Hyperthyroidism increased in both sexes (P < 0.001) and in all age groups: 0-19, 20-39, 40-59, and 60+ yr (P for trend <0.001). The increase was relatively highest in young adults aged 20-39 yr: late mandatory IF (percent increase from baseline), age 20-39, 160%, P < 0.001; age 40-59, 29%, P < 0.01; age 60+ yr, 13%, P = not significant. Even a cautious iodization of salt results in an increase in the incidence rate of hyperthyroidism. Contrary to current concepts, many of the new cases were observed in young subjects, and are presumably of autoimmune origin. Furthermore, monitoring is expected to show a decrease in the number of elderly subjects suffering from nodular hyperthyroidism.

The terrorist attacks that occurred on September 11, 2001 (hereafter referred to as 9/11) in the United States had a profound impact on the physical and mental health of Americans, but the effects beyond the United States are largely unknown. To understand the wider aftermath, we examined the consequences of the 9/11 attacks on mental disorders in the Kingdom of Denmark. Utilizing population data from the Danish Psychiatric Central Research Register from 1995 to 2012, we used a time-series intervention approach to estimate the change in the incidence rate of mental disorders after the 9/11 attacks. Based on analyses of 1,448,250 contacts with psychiatric services, we found that the attacks were followed by an immediate 16% increase in the incidence rate of trauma- and stressor-related disorders. This surge dissipated approximately a year after 9/11. In contrast, no similar increases were found for other disorders. This is consistent with the prominent role of external stressors in the etiology of trauma- and stressor-related disorders. The results indicate that the effects of 9/11 on mental disorders extended across the Atlantic Ocean to Denmark. Thus, the impact of terrorist attacks on mental health is likely not limited to inhabitants of the country under attack; it also extends to people far away and without immediate relation to it. © The Author 2016.

Regionalization Lessons from Denmark.

PubMed

Vrangbaek, Karsten

2016-01-01

Denmark is a small Northern European country with an extensive welfare state and a strong commitment to maintaining a universal healthcare system. Like the other countries in the Nordic region, Denmark has a long tradition of democratically governed local and regional governments with extensive responsibilities in organizing welfare state services. The Danish healthcare system has demonstrated an ability to increase productivity, while at the same time maintaining a high level of patient satisfaction. Ongoing reforms have contributed to these results, as well as a firm commitment to innovation and coordination. Regions and municipalities in Denmark are governed by directly elected democratic councils. The Danish case is thus an example of democratic decentralization, but within a framework of national coordination and fiscal control. In spite of the difference in size and historical traditions there are also many similarities between Canada and Denmark, particularly in terms of health and social policy goals and aspirations, and in terms of the commitment to a comprehensive, universal healthcare system. These similarities provide interesting opportunities for comparison.

To compare domestic cannabis cultivation in Denmark and Finland to describe national characteristics in small-scale cannabis growing. A Web survey conducted among small-scale cannabis growers in Denmark (June to November 2008) and Finland (May to June 2009). Current cannabis growers (Denmark, 401; Finland, 1,054). Comparisons in regard to social background, growing history, practices, purposes and motives of growing, and perceptions of risks. Cannabis was cultivated primarily for own use, but sharing with friends and avoiding criminal circles also were significant motives for growing. Finnish growers prioritized indoor cultivation, whereas the Danes were more in favor of open-air plantations. Risks of getting caught by the police were observed to be greater in Finland. Growing for medical purposes was twice as prevalent in Finland as in Denmark. Cannabis growing is a stronger and more novel phenomenon in Finland than in Denmark, but both countries have been influenced by international trends. Finnish and Danish small-scale cannabis cultivators can be considered to be ideologically oriented lifestyle growers. Differences in the magnitude of the phenomenon may reflect differences in the availability and quality of cannabis in national drug markets. The Internet had promoted the spreading of the trend.

Dammeyer, Jesper; Marschark, Marc

2016-10-01

In Scandinavia and some other countries, a bilingual-bicultural approach to deaf education was celebrated in national programs from the mid-1980s until the broad popularity of cochlear implantation in middle 2000s created a shift back to an emphasis on spoken language for many deaf children. At the same time, only a few studies evaluated the long-term outcomes of bilingual-bicultural education, and several of their findings have raised questions about benefits of the approach. This study examined the level of educational attainment of 408 deaf individuals who attended primary school either before or during the period of bilingual-bicultural education in Denmark, both relative to a comparable hearing cohort. Beyond group comparisons, three logistic regression models were created to evaluate the prediction of educational attainment by a number of relevant variables. Compared to the hearing population, the deaf population had a significantly lower level of educational attainment both before and after the introduction of bilingual-bicultural education. Signed language and spoken language abilities, the kind of school attended, degree of hearing loss, parental hearing loss, and gender were found significantly to explain levels of educational attainment in the deaf population. © The Author 2016.

Comparison of output-based approaches used to substantiate bovine tuberculosis free status in Danish cattle herds.

2015-09-01

We compared two published studies based on different output-based surveillance models, which were used for evaluating the performance of two meat inspection systems in cattle and to substantiate freedom from bovine tuberculosis (bTB) in Denmark. The systems were the current meat inspection methods (CMI) vs. the visual-only inspection (VOI). In one study, the surveillance system sensitivity (SSe) was estimated to substantiate the bTB free status. The other study used SSe in the estimation of the probability of freedom (PFree), based on the epidemiological concept of negative predictive value to substantiate the bTB free status. Both studies found that changing from CMI to VOI would markedly decrease the SSe. However, the two studies reported diverging conclusions regarding the effect on the substantiation of Denmark as a bTB free country, if VOI were to be introduced. The objectives of this work were: (a) to investigate the reasons why conclusions based on the two models differed, and (b) to create a hybrid model based on elements from both studies to evaluate the impact of a change from CMI to VOI. The hybrid model was based on the PFree approach to substantiate freedom from bTB and was parametrized with inputs according to the newest available information. The PFree was updated on an annual basis for each of 42 years of test-negative surveillance data (1995-2037), while assuming a low (<1%) annual probability of introduction of bTB into Danish cattle herds. The most important reasons for the difference between the study conclusions were: the approach chosen to substantiate the bTB free status (SSe vs. PFree) and the number of years of surveillance data considered. With the hybrid model, the PFree reached a level >95% after the first year of surveillance and remained ≥96% with both the CMI and VOI systems until the end of the analyzed period. It is appropriate to use the PFree of the surveillance system to substantiate confidence in bTB free status, when test-negative surveillance results can be documented over an extended period of time, while maintaining a low probability of introduction of bTB into the cattle population. For Denmark, the probability of introduction of bTB should be kept <1% on an annual basis to sustain the high confidence in freedom over time. The results could be considered when deciding if the CMI can be replaced by VOI in cattle abattoirs of countries for which bTB freedom can be demonstrated. Copyright © 2015 Elsevier B.V.

The potential for outbreaks due to Enteroviruses (EV) with respiratory tropism, such as EV-D68, and the detection of new and rare EV species C is a concern. These EVs are typically not detected in stool specimens and may therefore be missed by standard EV surveillance systems. Following the North American outbreak of EV-D68 in 2014, Denmark piloted an enhanced EV surveillance system that included the screening of respiratory samples. We aim to report clinical manifestations and phylogenetic descriptions from the rare and emerging EVs identified thereby demonstrating the usefulness of this system. Positive EV samples received through the enhanced non-polio EV pilot surveillance system were characterized by sequencing fragments of VP1, VP2 and VP4 capsid proteins and clinical observations were compiled. Between January 2015 and October 2016, six cases of rare genotypes EV-C104, C105 and C109 and nine cases of EV-D68 were identified. Patients presented with mild to moderately severe respiratory illness; no paralysis occurred. Distinct EV-C104, EV-C109 and EV-D68 sequences argue against a common source of introduction of these genotypes in the Danish population. The enhanced EV surveillance system enabled detection and characterization of rare EVs in Denmark. In order to improve our knowledge of and our preparedness against emerging EVs, public health laboratories should consider expanding their EV surveillance system to include respiratory specimens.

Ionizing radiation has been shown to produce negative effects on organisms, although little is known about its ecological and evolutionary effects. As a study model, we isolated bacteria associated with feathers from barn swallows Hirundo rustica from three study areas around Chernobyl differing in background ionizing radiation levels and one control study site in Denmark. Each bacterial community was exposed to four different γ radiation doses ranging from 0.46 to 3.96 kGy to test whether chronic exposure to radiation had selected for resistant bacterial strains. Experimental radiation duration had an increasingly overall negative effect on the survival of all bacterial communities. After exposure to γ radiation, bacteria isolated from the site with intermediate background radiation levels survived better and produced more colonies than the bacterial communities from other study sites with higher or lower background radiation levels. Long-term effects of radiation in natural populations might be an important selective pressure on traits of bacteria that facilitate survival in certain environments. Our findings indicate the importance of further studies to understand the proximate mechanisms acting to buffer the negative effects of ionizing radiation in natural populations. PMID:26976674

There is a number of systems for the provision of oral health care, one of which is the Nordic model of centrally planned oral health care provision. This model has historically been firmly based on the concept of a welfare state in which there is universal entitlement to services and mutual responsibility and agreement to financing them. This study reports and analyses oral health care provision systems and developments in oral health policy in the Nordic countries (Denmark, Finland, Iceland, Norway and Sweden) since 1990. Descriptions of and data on the oral health care provision systems in the Nordic countries were obtained from the Chief Dental Officers of the five countries, and contemporary scientific literature was appraised using cross-case analyses to identify generalisable features. It was found that in many respects the system in Iceland did not follow the 'Nordic' pattern. In the other four countries, tax-financed public dental services employing salaried dentists were complemented by publicly subsidised private services. Additional, totally private services were also available to a variable extent. Recently, the availabilty of publicly subsidised oral health care has been extended to cover wider groups of the total population in Finland and Sweden and, to a smaller extent, in Denmark. Concepts from market-driven care models have been introduced. In all five countries, relative to the national populations and other parts of the world, there were high numbers of dentists, dental hygienists and technicians. Access to oral health care services was good and utilisation rates generally high. In spite of anticipated problems with increasing health care costs, more public funds have recently been invested in oral health care in three of the five countries. The essential principles of the Nordic model for the delivery of community services, including oral health care, i.e. universal availability, high quality, finance through taxation and public provision, were still adhered to in spite of attempts at privatisation during the 1990 s. It appeared that, in general, the populations of the Nordic countries still believed that there was a need for health and oral health care to be paid for from public funds.

Latitudinal-Related Variation in Wintering Population Trends of Greylag Geese (Anser Anser) along the Atlantic Flyway: A Response to Climate Change?

The unusually high quality of census data for large waterbirds in Europe facilitates the study of how population change varies across a broad geographical range and relates to global change. The wintering population of the greylag goose Anser anser in the Atlantic flyway spanning between Sweden and Spain has increased from 120 000 to 610 000 individuals over the past three decades, and expanded its wintering range northwards. Although population sizes recorded in January have increased in all seven countries in the wintering range, we found a pronounced northwards latitudinal effect in which the rate of increase is higher at greater latitudes, causing a constant shift in the centre of gravity for the spatial distribution of wintering geese. Local winter temperatures have a strong influence on goose numbers but in a manner that is also dependent on latitude, with the partial effect of temperature (while controlling for the increasing population trend between years) being negative at the south end and positive at the north end of the flyway. Contrary to assumptions in the literature, the expansion of crops exploited by greylag geese has made little contribution to the increases in population size. Only in one case (expansion of winter cereals in Denmark) did we find evidence of an effect of changing land use. The expanding and shifting greylag population is likely to have increasing impacts on habitats in northern Europe during the course of this century.

This report is a follow-up to a study on fatal poisoning in drug addicts conducted in 2012 by a Nordic working group. Here we analyse data from the five Nordic countries: Denmark, Finland, Iceland, Norway and Sweden. Data on sex, number of deaths, places of death, age, main intoxicants and other drugs detected in the blood were recorded. National data are presented and compared between the Nordic countries and with data from similar studies conducted in 1991, 1997, 2002 and 2007. The death rates (number of deaths per 100,000 inhabitants) increased in drug addicts in Finland, Iceland and Sweden but decreased in Norway compared to the rates in earlier studies. The death rate was stable in Denmark from 1991 to 2012. The death rate remained highest in Norway (5.79) followed by Denmark (5.19) and Iceland (5.16). The differences between the countries diminished compared to earlier studies, with death rates in Finland (4.61) and Sweden (4.17) approaching the levels in the other countries. Women accounted for 15-27% of the fatal poisonings. The median age of the deceased drug addicts was still highest in Denmark, and deaths of addicts >45 years old increased in all countries. Opioids remained the main cause of death, but medicinal opioids like methadone, buprenorphine, fentanyl and tramadol mainly replaced heroin. Methadone was the main intoxicant in Denmark and Sweden, whereas heroin/morphine caused the most deaths in Norway. Finland differed from the other Nordic countries in that buprenorphine was the main intoxicant with only a few heroin/morphine and methadone deaths. Deaths from methadone, buprenorphine and fentanyl increased immensely in Sweden compared to 2007. Poly-drug use was widespread in all countries. The median number of drugs per case varied from 4 to 5. Heroin/morphine, medicinal opioids, cocaine, amphetamines, benzodiazepines and alcohol were the main abused drugs. However, less widely used drugs, like gamma-hydroxybutyric acid (GHB), methylphenidate, fentanyl and pregabalin, appeared in all countries. New psychotropic substances emerged in all countries, with the largest selection, including MDPV, alpha-PVP and 5-IT, seen in Finland and Sweden. Copyright © 2015 Elsevier Ireland Ltd.

[Multiresistant tuberculosis in Denmark 1993-1996].

PubMed

Viskum, K; Kok-Jensen, A

1998-05-18

Infections with multiresistant tubercle bacilli have also become a problem in the rich part of the world. The reasons are lack of compliance in patients with life style problems and ineffectiveness of the health system due to lack of fundings. During a four year period, 1993-1996 ten patients were seen in Denmark with tuberculosis due to multiresistant Mycobacterium tuberculosis. Nine were infected abroad, one developed MDR-TB during treatment in Denmark. It is possible to cure these patients, but it is expensive and takes a long time. In the future more cases created within Denmark are likely to be seen due to lack of funding for the tuberculosis programme and, depending on immigration, further cases created abroad are expected.

Epidemiology of forearm fractures in adults in Denmark: national age- and gender-specific incidence rates, ratio of forearm to hip fractures, and extent of surgical fracture repair in inpatients and outpatients.

2015-01-01

National epidemiological studies of forearm fractures are scarce. We examined in- and outpatient rates in Denmark, including anatomical location, surgery, hospitalization ratio, recurrent fractures, and ratio of forearm to hip fractures. This may be useful for triangulation in countries with less detailed information. Rates were higher than previously estimated. Despite a significant contribution to the overall burden of osteoporotic, nonvertebral fractures, relatively little information is available about age- and gender-specific incidence rates for many countries including Denmark. We used national individual patient data on inpatient and outpatient treatment to calculate rates of forearm fractures, taking readmissions into account, with subtables for distal and proximal fractures. We also calculated ratios of forearm to hip fractures that may be useful when imputing forearm fracture rates from other administrative sources. In addition, we report the rates of hospital admission and the rates of surgical treatment, allowing readers to extrapolate from the number of admissions or surgical procedures to incidence rates, should their data sources be less comprehensive. Forearm fracture rates were 278 per 100,000 patient years in men aged 50+ and 1,110 per 100,000 in women aged 50+. The female to male incidence rate ratio was 4.0 for the age group 50+ but close to unity in persons aged 40 or under. Two thirds of patients were treated on an outpatient basis with little difference across age and gender strata. Four out of five fractures were treated conservatively. The rate of forearm fractures in Denmark was somewhat higher in both genders than recently imputed from hip fracture rates and were close to the rates previously reported in studies from Norway and Sweden. The rates of forearm fracture in Denmark are higher than previously estimated and very similar to the high risk reported from studies in Norway and Sweden.

The long range transport of birch (Betula) pollen from Poland and Germany causes significant pre-season concentrations in Denmark

In Denmark, where birch pollen is considered to be among the most important allergenic pollen, about one million people suffer from seasonal allergic rhinitis. In Denmark, the official reported pollen forecast is based on the daily weather forecast, the pollen calendar and local 24-h measurements. Birch pollen has the potential for long-range transport but the present Danish pollen forecast does not account for birch pollen being transported into the country from distant sources.. Long-range transport episodes are intermittent and often out of the main pollen season, where individuals in general will be medically unprotected. Here we use an integrated approach to investigate whether or not Denmark receives significant quantities of birch pollen from Poland and Germany before local trees start to flower. In 2006 we used a combination of phenological observations and pollen measurements in Poland (Poznań) and Denmark (Copenhagen). Seasonal and diurnal variations in birch pollen measurement from Copenhagen (2000-2006) were examined with the aim of identifying pre-seasonal episodes originating from long-range transport. The 2.5% accumulation method was used for identifying start of season. If daily pollen counts exceeded 30 grains/m3 either before the local flowering season began or on the actual start day, the episode was chosen for investigation with back trajectory analysis. A birch forest inventory for Northern Europe was produced and implemented in DEHM-Pollen along with a simple unified pollen release model SUPREME to investigate the 2006 campaign in detail. In 2006, full flowering took place in Poznan between 20th and 28th of April and daily concentrations varied between 739 and 2169 grains/m3. In Copenhagen phenological observations showed that local flowering was initiated the 2nd of May. In Copenhagen several episodes with pollen concentrations at 108, 244 and 41 grains/m3 were recorded the 23rd, 26th and 27th of April, respectively. Back-trajectory analysis showed that for those tree dates the origin of the air masses was Poland including the Poznan region. 11 possible pre-seasonal long-range transport episodes in 2000-2006 were identified during analyses of the measured pollen data. All possible long-range transport episodes were investigated with back trajectories. In all investigated episodes, the air masses Copenhagen originated directly from either Germany or Poland. The model results from DEHM pollen for 2006 show several episodes in Copenhagen with high pollen concentration for the 23rd - 24th and 26th - 27th of April, respectively. These pre-seasonal peaks in 2006 were modelled well with respect to timing and magnitude. During this period the SUPREME model only predicts birch pollen emission south of Denmark. Long-range transport episodes of birch pollen from Poland and Germany has happened almost every year since 2000 and it is therefore likely that this is a general pattern. It is shown that DEHM-Pollen for the year 2006 is able to simulate pre-seasonal pollen concentrations in Denmark, where key components include a well calibrated emission model and emission inventory. Furthermore, all model components are prepared for full implementation in the THOR air pollution and forecasting system. During pre-seasonal, pollen allergy patients are in general medically unprotected. Such episodes will therefore have a full impact with respect to allergic reactions among the allergy patients. The use of the integrated approach improves knowledge of such episodes. Furthermore, an implementation of DEHM-Pollen in the THOR system has the potential to provide early warnings of severe pre-seasonal pollen episodes to the entire Danish population, by forecasting how far and how severe a possible pre-seasonal birch pollen cloud will progress into Denmark.

Desiccation and Mortality Dynamics in Seedlings of Different European Beech (Fagus sylvatica L.) Populations under Extreme Drought Conditions

European beech (Fagus sylvatica L., hereafter beech), one of the major native tree species in Europe, is known to be drought sensitive. Thus, the identification of critical thresholds of drought impact intensity and duration are of high interest for assessing the adaptive potential of European beech to climate change in its native range. In a common garden experiment with one-year-old seedlings originating from central and marginal origins in six European countries (Denmark, Germany, France, Romania, Bosnia-Herzegovina, and Spain), we applied extreme drought stress and observed desiccation and mortality processes among the different populations and related them to plant water status (predawn water potential, ΨPD) and soil hydraulic traits. For the lethal drought assessment, we used a critical threshold of soil water availability that is reached when 50% mortality in seedling populations occurs (LD50SWA). We found significant population differences in LD50SWA (10.5–17.8%), and mortality dynamics that suggest a genetic difference in drought resistance between populations. The LD50SWA values correlate significantly with the mean growing season precipitation at population origins, but not with the geographic margins of beech range. Thus, beech range marginality may be more due to climatic conditions than to geographic range. The outcome of this study suggests the genetic variation has a major influence on the varying adaptive potential of the investigated populations. PMID:27379105

We investigated the association between length of school education and 5-year prognosis of chronic obstructive lung disease (COPD), including exacerbations, hospital admissions and survival. We used sample of general population from two independent population studies: The Copenhagen City Heart Study and Copenhagen General Population Study. A total of 6,590 individuals from general population of Copenhagen with COPD defined by the Global initiative for obstructive lung disease criteria were subdivided into 4 groups based on the length of school education: 1,590 with education < 8 years; 3,131 with education 8-10 years, 1,244 with more than 10 years, but no college/university education and 625 with college/university education. Compared with long education, short education was associated with current smoking (p < 0.001), higher prevalence of respiratory symptoms (p < 0.001) and lower forced expiratory volume in the first second in percent of predicted value (FEV1%pred) (p < 0.001). Adjusting for sex, age, FEV1%pred, dyspnea, frequency of previous exacerbations and smoking we observed that shortest school education (in comparison with university education), was associated with a higher risk of COPD exacerbations (hazards ratio 1.65, 95% CI 1.15-2.37) and higher risk of all-cause mortality (hazards ratio 1.96, 95% CI 1.28-2.99). We conclude that even in an economically well-developed country with a health care system (which is largely free of charge), low socioeconomic status, assessed as the length of school education, is associated with a poorer clinical prognosis of COPD.

Working hours and all-cause mortality in relation to the EU Working Time Directive: a Danish cohort study.

2018-03-12

In keeping with the need to protect the safety and health of workers, the EU Working Time Directive stipulates that a worker's average working time for each 7-day period, including overtime, does not exceed 48 h. It has, however, not been settled whether or not the threshold at 48 working hours a week is low enough to protect against excess mortality from long work weeks. The aim of the present study was to examine all-cause mortality in relation to weekly working hours among employees in the general population of Denmark. A special attention was given to mortality rates among employees with moderately long work weeks, 41-48 h. Interview data from cohorts of 20-64 year-old employees were drawn from the Danish Labour Force Survey. The participants (N = 159 933) were followed through national registers from the end of the calendar year of the interview (1999-2013) until the end of 2014. Rate ratios (RRs) for all-cause mortality were estimated as a function of weekly working hours while controlling for age, sex, social class, night-time work and calendar year. We found 3374 deaths during an average follow-up time of 7.7 years. With 32-40 working hours a week as reference, the RRs for all-cause mortality were 0.75 (95% CI: 0.66-0.85) for 41-48 and 0.92 (0.80-1.05) for >48 h. Mortality rates in Denmark are significantly lower among employees with moderately long work weeks than they are among full-time employees without overtime work.

Does drinking water influence hospital-admitted sialolithiasis on an epidemiological level in Denmark?

2015-01-01

Objectives Sialolithiasis, or salivary stones, is not a rare disease of the major salivary glands. However, the aetiology and incidence remain largely unknown. Since sialoliths are comprised mainly of calcium phosphate salts, we hypothesise that drinking water calcium levels and other elements in drinking water could play a role in sialolithiasis. Owing to substantial intermunicipality differences in drinking water composition, Denmark constitutes a unique environment for testing such relations. Design An epidemiological study based on patient data extracted from the National Patient Registry and drinking water data from the Geological Survey of Denmark and Greenland retrieved as weighted data on all major drinking water constituents for each of the 3364 waterworks in Denmark. All patient cases with International Statistical Classification of Diseases 10th Revision (ICD-10) codes for sialolithiasis registered between the years 2000 and 2010 were included in the study (n=3014) and related to the drinking water composition on a municipality level (n=98). Primary and secondary outcome measures Multiple regression analysis using iterative search and testing among all demographic and drinking water variables with sialolithiasis incidence as the outcome in search of possible relations among the variables tested. Results The nationwide incidence of hospital-admitted sialolithiasis was 5.5 cases per 100 000 citizens per year in Denmark. Strong relations were found between the incidence of sialolithiasis and the drinking water concentration of calcium, magnesium and hydrogen carbonate, however, in separate models (p<0.001). Analyses also confirmed correlations between drinking water calcium and magnesium and their concentration in saliva whereas this was not the case for hydrogen carbonate. Conclusions Differences in drinking water calcium and magnesium may play a role in the incidence of sialolithiasis. These findings are of interest because many countries have started large-scale desalination programmes of drinking water. PMID:25941183

To describe nepafenac use in the Netherlands and Denmark with reference to its approved indications. For context, we also describe the use of ketorolac and diclofenac. We identified users in the PHARMO Database Network (the Netherlands, 2008-2013) and the Danish national health registers (Denmark, 1994-2014). We described prevalence of cataract surgery and duration of use in patients with cataract surgery with and without diabetes. In the Netherlands, 9530 nepafenac users (mean age, 71 years; 60% women) contributed 12 691 therapy episodes, of which 21% had a recently recorded cataract surgery. Of 2266 episodes in adult non-diabetic patients with cataract surgery, 60% had one bottle dispensed (treatment duration ≤21 days). Of 441 episodes in adult diabetic patients with cataract surgery, 90% had up to two bottles dispensed (≤60 days). Denmark had 60 403 nepafenac users (mean age, 72 years; 58% women) and 73 648 episodes (41% had recorded cataract surgery). Of 26 649 nepafenac episodes in adult non-diabetic patients with cataract surgery, 92% had one bottle dispensed. Of 3801 episodes in adult diabetic patients with cataract surgery, 99.8% had up to two bottles dispensed. Use patterns of nepafenac, ketorolac and diclofenac were roughly similar in the Netherlands, but not in Denmark. Less than half of therapy episodes were related to cataract surgery; around 90% of episodes with surgery were within the approved duration. Underrecording of ophthalmic conditions and procedures was a challenge in this study. © 2017 The Authors Acta Ophthalmologica published by John Wiley & Sons Ltd on behalf of Acta Ophthalmologica Scandinavica Foundation.

The tragedy of becoming tired of living: Youth and young adults' suicide in Greenland and Denmark.

PubMed

Bolliger, Larissa; Gulis, Gabriel

2018-06-01

Suicide is a tremendous public health issue and worldwide the second leading cause of death among young people. In 2015, Greenland had the highest burden of disease due to self-harm with loss of 2,952.97 disability-adjusted life years per 100,000 inhabitants, more than six times as many as Denmark. What are possible reasons for Greenland's higher youth suicide rate compared to Denmark, despite being one kingdom of Denmark? Mixed methods in the form of qualitative, semi-structured interviews, the analysis of available data for 2003-2016 and a literature review were conducted with the aim to answer this question. Several exposures cause this difference, most significantly adverse effects of the colonial past, such as social issues and experienced traumas in Greenland compared to its former coloniser Denmark. The ongoing burden of youth suicide in Greenland requires enhanced actions of all stakeholders involved in suicide prevention, intervention and postvention.

There are few data available that describe the current anaesthetic management of children. We have analysed anaesthetic practice and peri-operative complications for children in Denmark aged less than two years. We conducted a population-based observational cohort study using the Danish Anaesthesia Database to identify children who received anaesthesia in hospital from 1 January 2005 until 31 December 2015. Data were combined with that from the Danish National Patient Registry and the Danish Civil Registration System. Age, sex, height, weight, ASA physical status, days in hospital before anaesthesia, number of anaesthetics per child, indications for anaesthesia, methods of anaesthesia, airway management and complications were all recorded. A total of 17,436 children (64% of whom were male) received 27,653 anaesthetics during the study period. In 58% of cases, the child had an ASA physical status score of 1. Thirty-seven percent had a previous anaesthetic episode. Seventy-nine percent were anaesthetised at a university hospital. The indications for anaesthesia were surgery (70%), diagnostic radiology (16%), non-surgical care (11%) and other indications (3%). General anaesthesia combining intravenous and inhalational agents was the most common approach for surgery (68%) and diagnostic radiology (47%). For non-surgical care, general anaesthesia using inhalational agents was the most common method (42%). Neuraxial blocks were used infrequently. The most common regional anaesthetic nerve block was an infraclavicular brachial plexus block (11%). Peri-operative complications occurred in 1.71% of cases. A large proportion of anaesthetics were conducted in children with comorbidities. Non-surgical indications for anaesthesia were frequent and peri-operative complications were rare. © 2018 The Association of Anaesthetists of Great Britain and Ireland.

Financial circumstances of the elderly in Denmark--now and in the coming years. Pension systems and other economic possibilities.

The situation concerning pensions in Denmark has been changing in recent years. There is a trend for the population itself has to pay into private pension to ensure a satisfactory financial situation after retirement. There are three categories of pensions and supplementary grants influencing the financial situation of the elderly: social-political grants, labour market political grants, and private arrangements. The national retirement pension is paid to everyone in accordance with certain rules. One condition is residence in Denmark for 40 years after reaching the age of 15. The pension age is 67 years. It is possible to receive early retirement pay or to obtain partial pension from the age of 60. This means that the age for retirement from the labour market on average is 62 years. Supplements to the national pension can be given as a net sum. Such a payment, however, makes it more difficult for the elderly person to overview his or her financial circumstances in retirement. The partial pension is a new form of pension which was introduced in 1986. About 2% of the 60-66 year-olds have taken advantage of this possibility, most of them independent trade men. In contrast, 105,000 wage earners are receiving early retirement pay, which is based on unemployment insurance. Certain considerations apply when the social pension is paid in a gross amount. This amount will not be free of tax. A number of special grants for the elderly will be included in the gross amount of the social pension. A system of that sort will make the financial circumstances of the retired person more clear.(ABSTRACT TRUNCATED AT 250 WORDS)

Iodization of salt is an effective strategy to prevent iodine deficiency disorders. Recent studies, however, indicate that increasing the iodine intake in a population may give rise to an increased incidence of hypothyroidism, but the association has not been fully clarified. In Denmark, iodization of salt was initiated in 1998 because of mild-to-moderate iodine deficiency. The aim of this study was to evaluate the effect of the raised iodine intake on the nationwide incident use of thyroid hormone replacement therapy (levothyroxine) to treat hypothyroidism. Data on all use of levothyroxine was extracted from the Register of Medicinal Product Statistics during the period 1995-2009 and linked to other nationwide registers by use of the Danish identification number. Persons with previous thyroid surgery were excluded. In the studied period 71,565 incident users were identified. The incidence rate increased 75% in the moderately iodine deficient region (72.2 incident users/100,000 person-years in 1997 to 126.6 in 2008) and 87% in the mildly deficient region (86.9-162.9). When stratified by sex and age-group (00-39, 40-64, 65+) the largest relative increase was seen among women in the youngest age-group, where more than a doubling was seen. The mechanisms behind the increase may be a result of iodine-induced hypothyroidism, although a higher diagnostic activity with regard to thyroid dysfunction and intensified treatment of subclinical hypothyroidism may also play a role. Our findings stress the need for caution when initiating iodine fortification programs to keep the intake within the optimal range, and the need for continuous monitoring.

The concentrations of seventeen pollutants (particulate mass fractions PM2.5 and PM10, a range of metals, inorganic gases and organic compounds) are for the first time analyzed in a screening of the carcinogenic risk at a resolution of 1 × 1 km2 in ambient air in three Nordic countries. Modelled annual mean air concentrations in 2010 show no exceedances of the EU air quality limit, guideline or target values. The only modelled exceedance of US-EPA 1:100,000 cancer risk concentrations (0.12 ng/m3, US-EPA IRIS, 2015) occurs for B(a)P in Denmark, for approximately 80% of the Danish population. However, the EU target value threshold of 1 ng/m3 for B(a)P is not exceeded in the modelled values in any parts of Denmark. No emission data for B(a)P were available for the whole domain of the other two considered Nordic countries and important uncertainties are still related to the emissions. Long-range transport is significant for the concentrations of all of the considered pollutants, except for B(a)P that commonly originates mostly from local residential wood combustion. The ambient air concentrations of NOx, SO2, Cd, Cr and Pb also have significant contributions from national sources; 45-65% for NOx and SO2, and for the metals from 15 to 60% in urban areas and from 1 to 20% in rural areas, within the considered Nordic area. High national contributions occur especially in urban air, due to primarily road traffic, residential wood combustion, energy production and industrial point sources. It is recommended to monitor the influence from residential wood combustion more extensively, and to analyze longer time trends for long-term human exposure.

Changes in private alcohol importation after alcohol tax reductions and import allowance increases in Denmark

2010-01-01

AIMS This paper examines changes in alcohol import in Denmark between 2003 and 2006, after the excise tax on spirits in Denmark was lowered by 45% on October 1, 2003 and travellers’ allowances for alcohol import were increased on January1, 2004. Additionally, the paper seeks to develop a profile of alcohol importers and analyse the relation between the distance to the German border and import behaviour, as Germany is the main alcohol import country for Denmark. DATA Cross-sectional and panel data from Denmark, from 2003 to 2006, were analyzed. Samples were collected by telephone interviews, using random digit dialing. RESULTS While the percentage of people who imported alcohol fell over time, the amount of alcohol purchased rose for those who did import. Distance to the German border was inversely related to the likelihood of importing and the level of imported amounts. Heavy drinkers and those with higher incomes were more likely to import, and heavy drinkers imported higher amounts than moderate drinkers or abstainers. CONCLUSION Distance of residence from the German border, socio-economic status and drinking behaviour are related to private alcohol import in Denmark. Policy changes resulted in a shift to fewer people importing higher amounts of alcohol so that the overall import level did not change substantially. PMID:21532978

Introduction of human papillomavirus vaccination in Nordic countries.

Cervical screening has helped decrease the incidence of cervical cancer, but the disease remains a burden for women. Human Papillomavirus (HPV) vaccination is now a promising tool for control of cervical cancer. Nordic countries (Denmark, Finland, Greenland, Iceland, Norway and Sweden) are relatively wealthy with predominantly publicly paid health care systems. The aim of this paper was to provide an update of the current status of introduction of HPV vaccine into the childhood vaccination programs in this region. Data on cervical cancer, cervical screening programs, childhood immunization and HPV vaccination programs for Nordic countries were searched via PubMed and various organizations. We furthermore contacted selected experts for information. The incidence of cervical cancer is highest in Greenland (25 per 100,000, age standardized, World Standard Population, ASW) and lowest in Finland (4 per 100,000 ASW) and rates in the other Nordic countries vary between 7 and 11 per 100,000 ASW. Greenland and Denmark were first to introduce HPV vaccination, followed by Norway. Vaccination programs are underway in Sweden and Iceland, while Finland has just recently recommended introduction of vaccination. HPV vaccination has been intensively debated, in particular in Denmark and Norway. In Nordic countries with a moderate risk of cervical cancer and a publicly paid health care system, the introduction of HPV vaccination was a priority issue. Many players became active, from the general public to health professionals, special interest groups, and the vaccine manufacturers. These seemed to prioritize different health care needs and weighed differently the uncertainty about the long-term effects of the vaccine. HPV vaccination posed a pressure on public health authorities to consider the evidence for and against it, and on politicians to weigh the wish for cervical cancer protection against other pertinent health issues.

Earlier it has been found that female Seventh-day Adventists (SDA) and Baptists have an increased incidence of psychiatric affective disorders, in contrast to findings that religious practice is associated with better health. In this study, we examined whether the increase in incidence is due to less use of prescribed antidepressants, sedatives and antipsychotics by members of these religious societies than by the general population. In a cohort study, we examined records of all drugs redeemed by 3121 SDA and 2888 Baptists and 29,817 age- and gender-matched members of the general population between 1995 and 2010 in the Danish Prescription Register and compared the prevalence and incidence of use of antidepressants, sedatives and antipsychotics. The prevalence of antidepressant use by women was lower in 1998 but no different from that in controls in 2003 and 2008; the prevalence of antidepressant use by men was higher in both 1998 and 2008 than in the Danish population. The incidence of antidepressant use was lower for female members in 1996-2000, but no difference was observed in the other periods. The prevalence and incidence of use of sedatives and antipsychotics did not consistently differ from those of the general population. The prevalence and incidence of use of antidepressants, sedatives and antipsychotics by female SDA and Baptists were not consistently lower than in the general Danish population. Our findings hence do not explain the increased incidence of psychiatric disorders among female members of these Danish religious societies.

To explore the variation in ovarian cancer survival in Denmark in the period 1978-2002 in relation to time since diagnosis, age at diagnosis, period of diagnosis, stage and histology. Register-based cohort study. Denmark in the period 1978-2002. Using the nationwide Danish Cancer Registry, we included a total of 13,035 women diagnosed with invasive ovarian cancer in Denmark in the period 1978-2002. Excess mortality risk analyses of five-year relative survival of ovarian cancer patients diagnosed in the period 1978-2002 with follow-up through 2006 were made based on data from the NORDCAN database. Five-year relative survival, excess mortality rate (ER) and relative excess mortality risk (RER) after an ovarian cancer diagnosis. The relative survival of Danish ovarian cancer patients slightly increased in the period 1978-2002. The ERs were highest in the first year following diagnosis, in particular in the first three months, and among older patients, even for localized and regional tumors. The pattern remained the same when stratified by histological subgroup. Older age at diagnosis, earlier period of diagnosis, more advanced stage at diagnosis and being diagnosed with undifferentiated carcinoma predicted poorer survival among Danish ovarian cancer patients diagnosed in the period 1978-2002. The survival of Danish ovarian cancer patients has slightly increased from 1978 through 2002. Despite this, the mortality rate of ovarian cancer in Denmark is still higher than in the other Nordic countries. Explanations for these differences are still to be identified.

Fatty acid composition including trans-fatty acids in edible oils and fats: probable intake in Indian population.

2012-10-01

The susceptibility of trans-fat to the human health risk prompted the Food and Agriculture Organization (FAO) and World Health Organization (WHO) to prepare regulations or compulsory claims for trans-fatty acids (TFA) in edible oils and fats. In this study, analysis of fatty acid composition and TFA content in edible oils and fats along with the possible intake of trans-fat in Indian population was carried out. The analysis was carried out as per the Assn. of Official Analytical Chemists (AOAC) methodology and the results were statistically analyzed. The average TFA content in nonrefined mustard and refined soybean oils exceeded by 1.16- to 1.64-fold as compared to the Denmark limit of 2% TFA in fats and oils destined for human consumption. In branded/nonbranded butter and butter oil samples, average TFA limit exceeded by 4.2- to 9.5-fold whereas hydrogenated vegetable oil (HVO) samples exceeded the limit by 9.8-fold, when compared to Denmark standards. The probable TFA intake per day through different oils in Indian population were found to be less than WHO recommendation. However Punjab having highest consumption of HVO (-15 g/d) showed 1.09-fold higher TFA intake than the WHO recommendation, which is alarming and may be one of the factors for high cardiovascular disease mortality rate that needs further elucidation. Thus there is a need to prescribe TFA limit for edible oil, butter, and butter oil in India and to reduce the already proposed TFA levels in HVO to safeguard the health of consumers. The probable daily intake of trans-fatty acid (TFA) especially through hydrogenated vegetable oil (HVO) was assessed. In absence of any specification for TFA and fatty acid composition for edible oils, butter, and butter samples, a pressing need was felt to prescribe TFA limit in India. The study indicates that TFA intake through HVO consumption is higher in States like Punjab than the recommended daily intake prescribed by WHO. Hence, strategies should be adopted to either decrease the consumption of HVO or to modify the industrial processing method of HVO with less content of TFA to safeguard the health of consumers. © 2012 Institute of Food Technologists®

Study protocol to a nationwide prospective cohort study on return to gainful occupation after stroke in Denmark 1996 - 2006

PubMed Central

2010-01-01

Background Successful return to work is regarded as one of the most important outcome factors for working-age post stroke patients. The present study will estimate the effect of various predictors on the odds of returning to work after stroke. Nearly twenty thousand 20-57 year-old stroke patients in Denmark who were gainfully occupied prior to the stroke will be included in the study. Methods/design Stroke patients will be followed prospectively through national registers. Multi-level logistic regression will be used to model the odds of being gainfully occupied ca. two years after the stroke as a function of the following predictors: Age (20-49 years, 50-57 years) gender, occupational class, self-employment (yes; no), onset calendar year (1996, 1997, ..., 2006), diagnosis (subarachnoid haemorrhage; intracerebral haemorrhage; cerebral infarction; stroke, not specified as haemorrhage or infarction) and 'type of municipality' (the variable is set to 1 if the person lived in a municipality which had a brain injury rehabilitation centre at the time of the stroke. Otherwise it is set to 0). Municipalities will be treated as the subjects while individual observations within municipalities are treated as correlated repeated measurements. Discussion Since our follow-up is done through registers and all people in the target population are included, the study is free from sampling bias, recall bias and non-response bias. The study is also strengthened by its size. The major weakness of the study is that it does not contain any stroke severity measures. Thus, it cannot accurately predict whether a particular stroke patient will in fact return to work. The study is, however, quite useful from a public health perspective. It can be used to estimate the proportion of patients in a certain group that is expected to return to work, and thereby provide a comparison material, which e.g. municipalities can use to evaluate their success in returning their stroke patients to work.

To analyze how prostate-specific antigen (PSA) screening and practice patterns has affected trends in tumor characteristics in men undergoing radical prostatectomy (RP) in the United States and Denmark. Unlike in the United States, PSA screening has not been recommended in Denmark. We performed an observational register study using pre- and postoperative data on 2168 Danish patients from Rigshospitalet, Copenhagen, Denmark, and 2236 patients from Stanford University Hospital, Stanford, CA, who underwent RP between 1995 and 2013. Patients were stratified according to Cancer of the Prostate Risk Assessment-Postsurgical (CAPRA-S) risk groups and D'Amico risk classification and were clustered into 4 time periods (1995-1999, 2000-2004, 2005-2009, and 2010-2013). Temporal trends in the proportions of patients of a given variable at the 2 institutions were evaluated with Cochran-Armitage test for trends and chi-square testing. A total of 4404 patients were included. Temporal changes in preoperative PSA, age, grade, and stage was found in both cohorts. Median preoperative PSA declined in both cohorts, while median age increased, with the Danish cohort showing the greatest changes in both PSA and age. In both cohorts, there was a trend for higher-risk preoperative features before RP over time. In 2010-2013, 27.7% and 21.8% of the patients were in the D'Amico high-risk group at Copenhagen and Stanford, respectively. Despite recommendation against PSA screening in Denmark, Danish men undergoing RP at Rigshospitalet to a considerable extent now resemble American men undergoing RP at Stanford. At both sites, there is continued trend to reduce the number of men undergoing RP for low-risk prostate cancer. Copyright © 2017 Elsevier Inc. All rights reserved.

Iodine is essential for human health. Many countries have therefore introduced universal salt iodising (USI) programmes to ensure adequate intake for the populations. However, little attention has been paid to subnational differences in iodine intake from drinking water caused by naturally occurring spatial variations. To address this issue, we here present the results of a Danish nationwide study of spatial trends of iodine in drinking water and the relevance of these trends for human dietary iodine intake. The data consist of treated drinking water samples from 144 waterworks, representing approx. 45% of the groundwater abstraction for drinking water supply in Denmark. The samples were analysed for iodide, iodate, total iodine (TI) and other major and trace elements. The spatial patterns were investigated with Local Moran's I. TI ranges from <0.2 to 126 μg L(-1) (mean 14.4 μg L(-1), median 11.9 μg L(-1)). Six speciation combinations were found. Half of the samples (n = 71) contain organic iodine; all species were detected in approx. 27% of all samples. The complex spatial variation is attributed both to the geology and the groundwater treatment. TI >40 μg L(-1) originates from postglacial marine and glacial meltwater sand and from Campanian-Maastrichtian chalk aquifers. The estimated drinking water contribution to human intake varies from 0% to >100% of the WHO recommended daily iodine intake for adults and from 0% to approx. 50% for adolescents. The paper presents a new conceptual model based on the observed clustering of high or low drinking-water iodine concentrations, delimiting zones with potentially deficient, excessive or optimal iodine status. Our findings suggest that the present coarse-scale nationwide programme for monitoring the population's iodine status may not offer a sufficiently accurate picture. Local variations in drinking-water iodine should be mapped and incorporated into future adjustment of the monitoring and/or the USI programmes. Copyright © 2014 Elsevier B.V. All rights reserved.

Tackling childhood obesity: the importance of understanding the context.

PubMed

Knai, Cécile; McKee, Martin

2010-12-01

Recommendations to tackle major health problems such as childhood obesity may not be appropriate if they fail to take account of the prevailing socio-political, cultural and economic context. We describe the development and application of a qualitative risk analysis approach to identify non-scientific considerations framing the policy response to obesity in Denmark and Latvia. Interviews conducted with key stakeholders in Denmark and Latvia, undertaken following a review of relevant literature on obesity and national policies. A qualitative risk analysis model was developed to help explain the findings in the light of national context. Non-scientific considerations that appeared to influence the response to obesity include the perceived relative importance of childhood obesity; the nature of stakeholder relations and its impact on decision-making; the place of obesity on the policy agenda; the legitimacy of the state to act for population health and views on alliances between public and private sectors. Better recognition of the exogenous factors affecting policy-making may lead to a more adequate policy response. The development and use of a qualitative risk analysis model enabled a better understanding of the contextual factors and processes influencing the response to childhood obesity in each country.

At present there are no nephrology facilities in Greenland. Greenlandic patients with renal failure needing dialysis thus have to travel to Denmark to obtain treatment. For patients in haemodialysis this necessitates a permanent residence in Denmark. Our study was aimed at examining Greenlanders' preferences for establishing nephrology facilities in Greenland at Queen Ingrid's Hospital in Nuuk, and to estimate the associated change in welfare. Preferences were elicited using a discrete choice experiment (DCE). A random sample of 500 individuals of the general population was sent a postal questionnaire in which they were asked to consider the trade-offs of establishing nephrology facilities in Greenland as opposed to the current situation. This involved trading off the benefits of having such facilities in their home country against the costs of the intervention. Besides including a payment attribute described in terms of incremental tax payment, the DCE included two interventions attributes related to (1) the organisation of labour, and (2) the physical settings of the patients. Respondents succeeded in answering the DCE despite cultural and linguistic disparity. We found that all the included attributes had a significant effect on respondents' choices, and that respondents' answers to the DCE were in keeping with their values as stated in the questionnaire. DCE data was analyzed using a random parameter logit model reparametrized in willingness-to-pay space. The results showed that establishing facilities in Greenland were preferred to the current treatment in Denmark. The welfare estimate from the DCE, at DKK 18.74 million, exceeds the estimated annual costs of establishing treatment facilities for patients with chronic renal failure. Given the estimated confidence interval this result seems robust. Establishing facilities in Greenland therefore would appear to be welfare-improving, deriving positive net benefits. Despite the relatively narrow policy focus, we believe that our findings provide some insight into individuals' preferences for decentralization of public services and on citizens' views of 'self-governance' that go beyond the case of Greenland. More generally, this paper illustrates how DCE can be applied successfully to developing countries with culturally, demographically, and geographically distinct features.

A history of anorexia nervosa has been associated with a reduced risk of developing breast cancer. We investigated survival after breast cancer among women with a prior anorexia nervosa diagnosis compared with women in a population comparison group. This register-based study included combined data from Sweden, Denmark and Finland. A total of 76 and 1462 breast cancer cases identified among 22,654 women with anorexia nervosa and 224,619 women in a population comparison group, respectively, were included in the study. Hazard ratios (HR) for overall and breast cancer-specific mortality after breast cancer diagnosis were estimated using Cox regression. Cause of death was available only for Swedish and Danish women; therefore, the analysis on breast cancer-specific mortality was restricted to these women. We observed 23 deaths after breast cancer among anorexia nervosa patients and 247 among population comparisons. The overall mortality after the breast cancer diagnosis was increased in women with a history of anorexia nervosa compared with population comparisons (HR 2.5, 95% CI 1.6-3.9) after adjustment for age, period and extent of disease. Results were similar for overall (HR 2.3, 95% CI 1.4-3.6) and breast cancer-specific mortality (HR 2.1, 95% CI 1.3-3.6) among Swedish and Danish women. We found that female breast cancer patients with a prior diagnosis of anorexia nervosa have a worse survival compared with other breast cancer patients.

Introduction Excessive alcohol consumption increases the risk of many diseases and injuries, and the Global Burden of Disease 2010 study estimated that 6% of the burden of disease in Denmark is due to alcohol consumption. Alcohol consumption thus places a considerable economic burden on society. Methods We analysed the cost-effectiveness of six interventions aimed at preventing alcohol abuse in the adult Danish population: 30% increased taxation, increased minimum legal drinking age, advertisement bans, limited hours of retail sales, and brief and longer individual interventions. Potential health effects were evaluated as changes in incidence, prevalence and mortality of alcohol-related diseases and injuries. Net costs were calculated as the sum of intervention costs and cost offsets related to treatment of alcohol-related outcomes, based on health care costs from Danish national registers. Cost-effectiveness was evaluated by calculating incremental cost-effectiveness ratios (ICERs) for each intervention. We also created an intervention pathway to determine the optimal sequence of interventions and their combined effects. Results Three of the analysed interventions (advertising bans, limited hours of retail sales and taxation) were cost-saving, and the remaining three interventions were all cost-effective. Net costs varied from € -17 million per year for advertisement ban to € 8 million for longer individual intervention. Effectiveness varied from 115 disability-adjusted life years (DALY) per year for minimum legal drinking age to 2,900 DALY for advertisement ban. The total annual effect if all interventions were implemented would be 7,300 DALY, with a net cost of € -30 million. Conclusion Our results show that interventions targeting the whole population were more effective than individual-focused interventions. A ban on alcohol advertising, limited hours of retail sale and increased taxation had the highest probability of being cost-saving and should thus be first priority for implementation. PMID:24505370

Trichuris suis and T. trichiura are two different whipworm species that infect pigs and humans, respectively. T. suis is found in pigs worldwide while T. trichiura is responsible for nearly 460 million infections in people, mainly in areas of poor sanitation in tropical and subtropical areas. The evolutionary relationship and the historical factors responsible for this worldwide distribution are poorly understood. In this study, we aimed to reconstruct the demographic history of Trichuris in humans and pigs, the evolutionary origin of Trichuris in these hosts and factors responsible for parasite dispersal globally. Parts of the mitochondrial nad1 and rrnL genes were sequenced followed by population genetic and phylogenetic analyses. Populations of Trichuris examined were recovered from humans (n = 31), pigs (n = 58) and non-human primates (n = 49) in different countries on different continents, namely Denmark, USA, Uganda, Ecuador, China and St. Kitts (Caribbean). Additional sequences available from GenBank were incorporated into the analyses. We found no differentiation between human-derived Trichuris in Uganda and the majority of the Trichuris samples from non-human primates suggesting a common African origin of the parasite, which then was transmitted to Asia and further to South America. On the other hand, there was no differentiation between pig-derived Trichuris from Europe and the New World suggesting dispersal relates to human activities by transporting pigs and their parasites through colonisation and trade. Evidence for recent pig transport from China to Ecuador and from Europe to Uganda was also observed from their parasites. In contrast, there was high genetic differentiation between the pig Trichuris in Denmark and China in concordance with the host genetics. We found evidence for an African origin of T. trichiura which were then transmitted with human ancestors to Asia and further to South America. A host shift to pigs may have occurred in Asia from where T. suis seems to have been transmitted globally by a combination of natural host dispersal and anthropogenic factors.

Little has been published comparing the graduate medical education training structure and requirements across multiple countries. The goal of this study was to summarize and compare the characteristics of anesthesiology training programs in the USA, UK, Canada, Japan, Brazil, Denmark, and Switzerland as a way to better understand efforts to train anesthesiologists in different countries. Two physicians trained in each of the seven countries (convenience sample) were interviewed using a semi-structured approach. The interview was facilitated by use of a predetermined questionnaire that included, for example, the duration of post-medical school training and national requirements for certain rotations, a number of cases, faculty supervision, national in-training written exams, and duty hour limits. These data were augmented by review of each country's publicly available residency training documents as available on the internet. Post-medical school anesthesia residency duration varied: three years (Brazil), four years (USA), five years (Canada and Switzerland), six years (Japan and Denmark) to nine years (UK), as did the number of explicitly required clinical rotations of a defined duration: zero (Denmark), one (Switzerland and UK), four (Brazil), six (Canada), and 12 (USA). Minimum case requirements exist in the USA, Japan, and Brazil, but not in the other countries. National written exams taken during training exist for all countries studied except Japan and Denmark. The countries studied increasingly aim to have competency-based education with milestone assessments. Training duty hour limits also varied including for example 37 hours/week averaged over a one month with limitations on night duties (Denmark), a weekly average of 48 hours taken over a 17 week period (UK), 50 hours/week maximum (Switzerland), 60 hours/week maximum (Brazil), and 80 hours/week averaged over four weeks (USA). Some countries have highly structured training programs with multiple national requirements with training principally carried out at a home institution. Other countries have a more decentralized and unregulated approach with fewer (if any) specific case or rotation requirements, where the trainee creates his/her own customized training to meet broad objectives and goals. The countries studied have different national training requirements, unique duty hour rules and are at varying stages in transitioning to an outcome based model of residency.

The cesarean rates are low but increasing in most Nordic countries. Using the Robson classification, we analyzed which obstetric groups have contributed to the changes in the cesarean rates. Retrospective population-based registry study including all deliveries (3 398 586) between 2000 and 2011 in Denmark, Finland, Iceland, Norway and Sweden. The Robson group distribution, cesarean rate and contribution of each Robson group were analyzed nationally for four 3-year time periods. For each country, we analyzed which groups contributed to the change in the total cesarean rate. Between the first and the last time period studied, the total cesarean rates increased in Denmark (16.4 to 20.7%), Norway (14.4 to 16.5%) and Sweden (15.5 to 17.1%), but towards the end of our study, the cesarean rates stabilized or even decreased. The increase was explained mainly by increases in the absolute contribution from R5 (women with previous cesarean) and R2a (induced labor on nulliparous). In Finland, the cesarean rate decreased slightly (16.5 to 16.2%) mainly due to decrease among R5 and R6-R7 (breech presentation, nulliparous/multiparous). In Iceland, the cesarean rate decreased in all parturient groups (17.6 to 15.3%), most essentially among nulliparous women despite the increased induction rates. The increased total cesarean rates in the Nordic countries are explained by increased cesarean rates among nulliparous women, and by an increased percentage of women with previous cesarean. Meanwhile, induction rates on nulliparous increased significantly, but the impact on the total cesarean rate was unclear. The Robson classification facilitates benchmarking and targeting efforts for lowering the cesarean rates. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

OBJECTIVES--To study the cancer incidence in printing workers in Denmark. METHODS--The cohort of 15,534 men and 3593 women working in the printing industry in 1970 were followed up for death, emigrations, and incident cancer cases until the end of 1987. Their cancer incidence was compared with that of all economically active people in Denmark. The smoking and drinking habits reported by members of the printing trade unions at a survey in 1972 were compared with habits reported by members of other trade unions. RESULTS--Lung, bladder, renal pelvis, and primary liver cancers were in excess among the printing workers. The excess risks of lung cancer among the factory workers in newspaper and magazine production, of bladder cancer in typographers in printing establishments, of renal pelvis cancer in typographers and lithographers, and of primary liver cancer among lithographers and bookbinders exceeded those expected based on the reported smoking and drinking habits. CONCLUSION--Our results indicate, in line with a previous study from Manchester, that work with rotary letterpress printing was associated with an increased risk of lung cancer. The inconsistent results from studies on bladder cancer in printing workers may point to a risk confined to a certain subgroup. The sixfold risk of primary liver cancer in Danish lithographers warrants studies in other countries. PMID:8535493

Background The study was performed to determine the epidemiological, clinical, and histopathological characteristics and prognosis of primary mucosal melanoma of the head and neck (MMHN) in Denmark. Material and methods This was a national retrospective multicenter study of patients diagnosed with MMHN between 1982 and 2012 in Denmark. Data were retrieved from national databases and patient records. Incidence trends were examined for the entire period. We prepared survival curves and performed univariate and multivariate analysis for the period 1992-2012 to identify possible prognostic factors. Results No significant trends in incidence were found in the study period. The three-year overall and disease-free survival rates for MMHN were 46.5% and 35.5%, respectively. Negative margins was an independent predictor of disease-free survival, and age below 65, absence of distant metastases, and low overall TNM stage were predictors of overall survival. Radiotherapy did not improve survival significantly. Recurrence rates were high, even for patients with negative margins. Conclusions MMHN remains a rare disease with a poor prognosis, particularly for patients aged over 65, those with distant metastasis, and those with advanced TNM stage. Importantly, the rate of recurrence is lowest in patients with negative margins.

Biomedical research in Denmark enjoys a strong position at present but will be challenged by a new organization for all hospitals in Denmark beginning in 2007. It will be very important to recognize the importance of medical research as the cornerstone of optimal patient treatment in the new hospital organizations. Centralization with a focus on efficiency and low cost, as well as decentralization combined with the loss of university hospital functions, will further challenge the conditions of clinical research already seen worldwide and also experienced in Denmark.

Doctoral prepared nurses in Denmark and their scientific production between 1976 and 2005.

Nursing research in Denmark has evolved over the last 30 years. By 2005, 48 Danish nurses had earned a doctoral degree. The Danish Nurses Organization formalized a strategy for development of nursing research for the period 1999-2002. The strategy was evaluated in 2004. One point in the evaluation was that the nurses' publication of peer-reviewed articles in journals with an Impact Factor did not show in the bibliographic measure used in health sciences. The purpose of this study is to identify the number of Danish nurses holding a doctoral degree by the end of 2005 and to document their scientific production. A descriptive design based on a national register of all nurses in Denmark holding doctoral degrees was used to explore the curricula vitae and publication lists of 38 out of 48 (79%) nurses on the register. Authorship of all 48 graduated nurses was sought in the databases: PubMed and CINAHL. A pattern of growing engagement in publishing peer-reviewed articles was identified among the Danish nurses holding a doctoral degree. Fifty per cent of these doctoral prepared nurses published peer-reviewed papers. The majority apparently pursued a career in health sciences. Nursing as an academic discipline is evolving in Denmark but, with its roots in clinical nursing, scientists may have to be aware of the necessity to prevail as a discipline through scientific production.

Educational inequalities in parental care time: Cross-national evidence from Belgium, Denmark, Spain, and the United Kingdom.

Gracia, Pablo; Ghysels, Joris

2017-03-01

This study uses time-diary data for dual-earner couples from Belgium, Denmark, Spain, and the United Kingdom to analyze educational inequalities in parental care time in different national contexts. For mothers, education is significantly associated with parenting involvement only in Spain and the United Kingdom. In Spain these differences are largely explained by inequalities in mothers' time and monetary resources, but not in the United Kingdom, where less-educated mothers disproportionally work in short part-time jobs. For fathers, education is associated with parenting time in Denmark, and particularly in Spain, while the wife's resources substantially drive these associations. On weekends, the educational gradient in parental care time applies only to Spain and the United Kingdom, two countries with particularly large inequalities in parents' opportunities to engage in parenting. The study shows country variations in educational inequalities in parenting, suggesting that socioeconomic resources, especially from mothers, shape important variations in parenting involvement.

Recently, the Yfiler® Plus PCR Amplification Kit (Yfiler® Plus, Thermo Fisher Scientific, Waltham, MA, USA) was introduced. Yfiler® Plus amplifies 27 Y-chromosomal short tandem repeat loci (Y-STRs) and adds ten new Y-STRs to those analysed with the commonly used AmpFlSTR® Yfiler® PCR Amplification Kit (Yfiler®, Thermo Fisher Scientific, Waltham, MA, USA). Seven of the new Y-STRs are rapidly mutating Y-STRs (RM Y-STRs). In this study, 551 male individuals from Denmark, Greenland and Somalia were typed with Yfiler® Plus. The results were compared to those obtained with Yfiler® in the same individuals. Forensic and population genetic parameters were estimated for Yfiler® Plus. Yfiler® Plus had a higher power of discrimination than Yfiler® in all three populations. Compared to Yfiler®, Yfiler® Plus offers increased power of discrimination, which is obviously an advantage in crime case investigations. However, the inclusion of seven RM Y-STRs in Yfiler® Plus makes it less attractive for relationship testing because of the relatively high combined mutation rate, approximately 15%.

The population's attitude towards smoking bans in public arenas is important for their passing, implementation and compliance. Smoking bans are believed to reduce the social acceptability of smoking, and once people experience them, public support increases--also among pre-ban sceptics. This study aimed to examine the temporal changes in public attitude towards smoking bans in public arenas from 2007 to 2010 and whether these changes differed across educational attainment, smoking status and intention to quit among smokers. Data from two surveys among adults (aged 25-79 years) in 2007 and 2010 in the Capital Region of Denmark (n=36,472/42,504, response rate = 52.3) was linked with data on sex, age and educational attainment from central registers. Age-standardised prevalence of supportive attitude towards smoking bans was estimated. Temporal changes in supportive attitude were explored in workplaces, restaurants and bars using logistic regression models. The prevalence of supportive attitude towards smoking bans increased significantly in all arenas from 2007 to 2010. Positive temporal changes in supportive attitude towards smoking bans were seen across educational attainment, smoking status and intention to quit smoking in restaurants and across smoking status for smoking bans in workplaces and bars. The results of this study show that the public's attitude towards smoking in public arenas has changed after the implementation of a comprehensive smoking ban. This change in attitude can support implementation of future legislation on smoking and may lead to positive changes in smoking norms. © 2014 the Nordic Societies of Public Health.

Utilisation of antihyperglycaemic drugs in ten European countries: different developments and different levels.

The aim of this study was to compare developments in the utilisation of antihyperglycaemic drugs (AHGDs) in ten European countries. Data on the yearly utilisation of insulin and oral AHGDs were collected from public registers in Denmark, Finland, Norway, Sweden, Belgium, England, Germany, Italy, Portugal and Spain, and were expressed as defined daily doses per 1,000 inhabitants per day. Total AGHD utilisation increased everywhere, but at different rates and levels. Insulin utilisation doubled in England and Germany, but hardly changed in Belgium, Portugal or Italy. Sulfonylurea utilisation doubled in Spain, England and Denmark but was reduced in Germany and Sweden. Metformin utilisation increased greatly everywhere. There were two- to three-fold differences in AHGD utilisation even between neighbouring countries. In Finland, there were more users of both insulin (+120%) and oral AHGDs (+80%) than in Denmark, and the daily oral AHGD doses were higher. In Denmark and Sweden, AHGD utilisation was equal in subjects aged <45 years, but in those >or=45 years of age, both insulin and oral AHGD utilisation were twice as high in Sweden. The ubiquitous increase in AHGD utilisation, particularly metformin, seems logical, considering the increasing prevalence of type 2 diabetes and the results of the UK Prospective Diabetes Study. However, the large differences even between neighbouring countries are more difficult to explain, and suggest different habits and attitudes in terms of screening and management of type 2 diabetes.

Background Intermittent monitoring of fruit and vegetable intake at the population level is essential for the evaluation and planning of national dietary interventions. Yet, only a limited number of studies on time trends in fruit and vegetable intake among children and adolescents have been published internationally. In Denmark, national comprehensive campaigns to enhance fruit and vegetable consumption were initiated in 2001. This paper describes secular trends in fruit intake among Danish adolescents by six comparable school surveys from 1988 to 2006. The paper demonstrates and discusses the consequences of measurement changes introduced in long-term trend analyses. Methods We used Danish data from the international Health Behaviour in School-aged Children (HBSC) study collected in 1988, 1991, 1994, 1998, 2002 and 2006. Analyses were conducted on comparable questionnaire-based data from students aged 11, 13 and 15 total (n = 23,871) from a random sample of schools. Data on fruit intake were measured by a food frequency questionnaire. Due to changes in number of response categories beween surveys, different cut-points were analysed. Results The prevalence of students eating fruit at least once daily ranged from 78.3% among 13-year-old girls in 1988 to 17.3% among 15-year-old boys in 2002. Based on the six data collections, analyses of trends showed a significant decrease in prevalence of students eating fruit at least once daily from 1988 to 2002 (all p-values < 0.0001). In all age and gender groups, a significant increase in intake occurred between 2002 and 2006 (all p-values < 0.0065). Analyses of alternative cut-points revealed similar results. Conclusion Fruit consumption among Danish schoolchildren decreased from 1988 to 2002 with an increase since 2002. We suggest that the increase may be attributable to a nation-wide initiative conducted in Denmark since 2001 to increase the intake of fruit and vegetables in the population. Still, the results imply that a substantial proportion of Danish schoolchildren do not meet the nationally recommended daily intake of fruit. Our analyses indicate that the observed trends are not solely caused by methodological biases related to changes in measurements. PMID:18237390

Social inequality in health: dichotomy or gradient? A comparative study of problematizations in national public health programmes.

PubMed

Vallgårda, Signild

2008-01-01

Recent public health programmes from four countries: Denmark, England, Norway, and Sweden, are studied to analyse how social inequality in health is described, explained and suggested to be tackled, i.e., the problematization or the discursive process whereby the issue is framed and made accessible to political action. Social inequality in health is defined in these programmes both as a disadvantaged minority with major health problems, in contrast to the rest of the population, i.e., as a dichotomy; and as a gradient in which health problems are seen as increasing with lower social class or educational level. The causes of health inequality are identified as behaviour, social relations and underlying social structures. Policies aimed at reducing health inequality can be characterized as either in accordance with a residual welfare state model, targeting the disadvantaged, or a universal model, addressing the whole population. All countries have policies that are mixtures of these problematizations, but with some systematic differences between the countries. In this field England resembles the Scandinavian countries, as much as they resemble each other dispelling the idea of a Nordic or Scandinavian welfare state model.

Prevalence of sunburn and sun-related behaviour in the Danish population: a cross-sectional study.

2010-07-01

In Denmark, the incidence of melanoma has been increasing since the 1960s. Intermittent exposure to ultraviolet radiation and a history of sunburn and sunbed use are known risk factors. We describe the association between use of protective measures, sun-related behaviour and experience of sunburn in the Danish population three months after the start of the campaign. A population-based sample of 3,499 persons aged 15-59 years completed a questionnaire that included items on exposure to ultraviolet radiation. We examined the relations between sunburn and sun-related behaviour by logistic regression analysis. Within the previous 12 months, 35% of the study population had experienced sunburn. Sunburn became less frequent with age (odds ratio (OR) 4.44; 15-19 vs. 50-59) and skin type (OR 2.57; I vs. III). Sunburn was negatively associated with shade and clothing and positively with use of sunscreens. We found no significant difference in sunscreen use between intentional tanners who experienced sunburn and those who did not. A larger fraction of unintentional tanners with sunburn than those who were not sunburnt had used sunscreen. Sunscreen was used to prolong the time spent in the sun by 66% of sunburnt people; however, we found no association between duration of sun exposure and sunscreen use. Future campaigns to reduce the prevalence of sunburn in the Danish population must especially target young persons and intentional tanning, and they should emphasize that sunscreen cannot be used to extend the time spent in the sun and that shade and clothing provide the best protection against sunburn.

Head circumference growth among extremely preterm infants in Denmark has improved during the past two decades.

Treatment of extremely preterm and low birth weight infants is still evolving and improving. In this study, we evaluated if growth has improved from birth to two years of corrected age (CA) among extremely low birth weight (BW) and preterm born infants in Denmark. This was an observational study with comparison of head circumference (HC), weight and length growth in two Danish cohorts of extremely preterm (gestational age (GA) < 28 weeks) and extremely low birth weight (ELBW with a BW < 1,000 g) infants (A: 1994-1995 and B: 2004-2008). Infants in cohort A (n = 198) and B (n = 64) had a median GA and BW of 27 + 2 weeks and 948 g in A, and 27 + 3 weeks and 934 g in B. At discharge, infants in B compared with A had increased more in HC (p = 0.000), length (p = 0.008) and weight (p = 0.000). At two years CA, HC was still significantly larger in cohort B than A (p = 0.03), while no significant difference was recorded for length or weight. Growth during hospitalisation seems to have improved among extremely preterm and low birth weight infants from 1994-1995 to 2004-2008. This may be a result of improved nutrition in combination with improved intensive care during hospitalisation. Collection of data in the 2004-2008 cohort was supported by the Institute of Regional Health Services Research, the Egmont Foundation and the University of Southern Denmark. Collection of data from birth to two years of age in the 1994-1995 cohort was without financial support. For the 1994-1995 study, all eight regional Research Ethics Committees in Denmark at that time approved the study. The 2004-2008 study was approved by the Danish National Committee on Biomedical Research Ethics, and handling of data and registrations were approved by the Danish Data Protection Agency.

Smoking is the most important single preventable cause of a variety of common diseases, and a considerable share of premature death is attributable to smoking. Although the effects of smoking on morbidity and mortality are widely recognized, little is known about the impact of smoking on early retirement due to chronic disease. The objective of the study is to determine the effects of smoking behaviour on early retirement due to permanent disability in a large sample of the general population. Follow-up study based on data from three longitudinal population studies conducted in the Copenhagen area. The final study population comprised 9,053 persons, 5,623 men and 3,430 women. Endpoint was grant of disability pension in the period 1980-1985. Baseline information was obtained from a self-administered questionnaire. Information about disability pensions was obtained from Statistics Denmark. Data analysis was performed by univariate and multiple logistic regression analyses. Smoking was found to be strongly associated with the risk of being granted a disability pension after adjustment for various confounders. The risk increased with daily consumption reaching a maximum odds ratio of 5.66 (1.88-17.00) and 5.61 (2.11-14.92) in heavily smoking men and women, respectively, who were below age 60. Smokers are at considerably higher risk of early retirement due to chronic disease. In addition to the burden of disease, this leads to social and economic problems for the individual and has a significant economic impact on society.

In 1999, concerns were raised that vaccines containing the preservative Thimerosal might increase the risk of autism and/or other neurodevelopmental disorders. Between the mid-1980s through the late-1990s, we compared the prevalence/incidence of autism in California, Sweden, and Denmark with average exposures to Thimerosal-containing vaccines. Graphic ecologic analyses were used to examine population-based data from the United States (national immunization coverage surveys and counts of children diagnosed with autism-like disorders seeking special education services in California); Sweden (national inpatient data on autism cases, national vaccination coverage levels, and information on use of all vaccines and vaccine-specific amounts of Thimerosal); and Denmark (national registry of inpatient/outpatient-diagnosed autism cases, national vaccination coverage levels, and information on use of all vaccines and vaccine-specific amounts of Thimerosal). In all three countries, the incidence and prevalence of autism-like disorders began to rise in the 1985-1989 period, and the rate of increase accelerated in the early 1990s. However, in contrast to the situation in the United States, where the average Thimerosal dose from vaccines increased throughout the 1990s, Thimerosal exposures from vaccines in both Sweden and Denmark-already low throughout the 1970s and 1980s-began to decrease in the late 1980s and were eliminated in the early 1990s. The body of existing data, including the ecologic data presented herein, is not consistent with the hypothesis that increased exposure to Thimerosal-containing vaccines is responsible for the apparent increase in the rates of autism in young children being observed worldwide.

Diversity and geographical distribution of Flavobacterium psychrophilum isolates and their phages: patterns of susceptibility to phage infection and phage host range.

Flavobacterium psychrophilum is an important fish pathogen worldwide that causes cold water disease (CWD) or rainbow trout fry syndrome (RTFS). Phage therapy has been suggested as an alternative method for the control of this pathogen in aquaculture. However, effective use of bacteriophages in disease control requires detailed knowledge about the diversity and dynamics of host susceptibility to phage infection. For this reason, we examined the genetic diversity of 49 F. psychrophilum strains isolated in three different areas (Chile, Denmark, and USA) through direct genome restriction enzyme analysis (DGREA) and their susceptibility to 33 bacteriophages isolated in Chile and Denmark, thus covering large geographical (>12,000 km) and temporal (>60 years) scales of isolation. An additional 40 phage-resistant isolates obtained from culture experiments after exposure to specific phages were examined for changes in phage susceptibility against the 33 phages. The F. psychrophilum and phage populations isolated from Chile and Denmark clustered into geographically distinct groups with respect to DGREA profile and host range, respectively. However, cross infection between Chilean phage isolates and Danish host isolates and vice versa was observed. Development of resistance to certain bacteriophages led to susceptibility to other phages suggesting that "enhanced infection" is potentially an important cost of resistance in F. psychrophilum, possibly contributing to the observed co-existence of phage-sensitive F. psychrophilum strains and lytic phages across local and global scales. Overall, our results showed that despite the identification of local communities of phages and hosts, some key properties determining phage infection patterns seem to be globally distributed.

We examined the association between sports and other leisure-time physical activities during pregnancy and birth weight of babies born after 37 completed weeks of gestation. All Danish-speaking pregnant women attending routine antenatal care at the Department of Obstetrics, Aarhus University Hospital, Denmark, from August 1989 to September 1991 were invited to participate in the study. A total of 4458 healthy women who delivered after 37 completed gestational weeks participated in this study. The associations between sports (0, 1-2, 3+ h/week) or leisure-time physical activity (sedentary, light, and moderate to heavy) and birth weight were examined by linear and logistic regression and adjusted for potential confounding factors such as smoking, parity, schooling, pre-pregnancy body mass index and gestational age. The results showed that pregnant women who practiced sports or were moderate to heavy leisure-time physical active during the early second or the early third trimester gave birth to infants with a similar birth weight as inactive women. The proportion of newborns with a low (<2500 g) or a high birth weight (>/=4500 g) was also unchanged. In conclusion, in this large population-based study, we found no association between sports and leisure-time physical activity and low-birth weight, high-birth weight, or average-birth weight.

An intake of trans-fatty acids of 5 grams per day is associated with an increase of 25% in the risk of ischemic heart disease. In 2004 Denmark, as the first country in the world, introduced a limitation on the content of industrially produced trans-fatty acids in foods. The amount in a "high-trans menu" consisting of popular foods was, from 2001 to 2005, reduced in Denmark from 30 g to <1 g. The amount in the same menu bought in countries within and outside the European Union is 20-40 g. During a period of just a few years, Denmark has thus eliminated a risk factor for ischemic heart disease without noticeable side effects for consumers. This risk factor is, however, still present in many other countries.

There is a need for follow-up studies of the familial situation of multiple sclerosis (MS) patients. To evaluate the probability of MS patients to remain in marriage or relationship with the same partner after onset of MS in comparison with the population. All 2538 Danes with onset of MS 1980-1989, retrieved from the Danish MS-Registry, and 50,760 matched and randomly drawn control persons were included. Information on family status was retrieved from Statistics Denmark. Cox analyses were used with onset as starting point. Five years after onset, the cumulative probability of remaining in the same relationship was 86% in patients vs. 89% in controls. The probabilities continued to deviate, and at 24 years, the probability was 33% in patients vs. 53% in the control persons (p < 0.001). Among patients with young onset (< 36 years of age), those with no children had a higher risk of divorce than those having children less than 7 years (Hazard Ratio 1.51; p < 0.0001), and men had a higher risk of divorce than women (Hazard Ratio 1.33; p < 0.01). MS significantly affects the probability of remaining in the same relationship compared with the background population.

Mental health problems are associated with women's reproductive decisions and predict poor mental health outcomes after abortion and childbirth. To study whether having a first-trimester induced abortion influenced the risk of psychiatric readmission and compare findings with readmission risk in women with mental disorders giving birth. Survival analyses were performed in a population-based cohort study merging data from the Danish Civil Registration System, the Danish Psychiatric Central Register, and the Danish National Hospital Register from January 1,1994, to December 31, 2007. Denmark. All women born in Denmark between 1962 and 1992 with a record of 1 or more psychiatric admissions at least 9 months before a first-time first-trimester induced abortion or childbirth. Main Outcome Measure  Readmission at a psychiatric hospital with any type of mental disorder from 9 months before to 12 months after a first-time first-trimester induced abortion or childbirth. Relative risk (RR) for readmission risk 9 to 0 months before a first-trimester induced abortion was 0.95 (95% CI, 0.73-1.23) compared with the first year after the abortion. This contrasts with a reduced risk of readmission before childbirth (RR, 0.56; 95% CI, 0.42-0.75) compared with the first year post partum. Proximity to previous psychiatric admission in particular predicted rehospitalization risks in both the abortion and the childbirth group. Risk of readmission is similar before and after first-time first-trimester abortion, contrasting with a marked increased in risk of readmission post partum. We speculate that recent psychiatric episodes may influence women's decisions to have an induced abortion; however, this decision does not appear to influence the illness course in women with a history of treated mental disorders.

The aim of this study was to describe and compare contraceptive use, fertility, birth, and abortion rates in the Nordic countries. National data on births, abortions, fertility rate (1975-2013), redeemed prescriptions of hormonal contraceptives and sales figures of copper intrauterine devices (2008-2013) among women 15-49 years of age in the Nordic countries were collected and analyzed. Use of hormonal contraceptives and copper intrauterine devices varied between 31 and 44%. The highest use was in Denmark (39-44%) and Sweden (40-42%). Combined hormonal contraception followed by the levonorgestrel-releasing intrauterine system were the most common methods. During 1975-2013 abortion rates decreased in Denmark (from 27/1000 women to 15/1000 women aged 15-44/1000 women) and Finland (from 20 to 10/1000 women), remained stable in Norway (≈16) and Sweden (≈20) and increased in Iceland (from 6 to 15/1000 women). Birth rates remained stable around 60/1000 women aged 15-44 in all countries except for Iceland where the birth rate decreased from 95 to 65/1000 women. Abortion rates were highest in the age group 20-24 years. In the same age group, Sweden had a lower contraceptive use (51%) compared with Denmark (59%) and Norway (56%) and a higher abortion rate 33/1000 compared with Denmark (25/1000) and Norway (27/1000). In contrast to the declining average fertility and birth rates in Europe, rates in the Nordic countries remain high and stable despite high contraceptive use and liberal access to abortion on women's request. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

To assess the cost-effectiveness of insulin detemir compared with Neutral Protamine Hagedorn (NPH) insulin when initiating insulin treatment in people with type 2 diabetes mellitus (T2DM) in Denmark, Finland, Norway, and Sweden. Efficacy and safety data were derived from a 20-week multi-centre randomized controlled head-to-head clinical trial comparing insulin detemir and NPH insulin in insulin naïve people with T2DM, and short-term (1-year) cost effectiveness analyses were performed. As no significant differences in HbA1c were observed between the two treatment arms, the model was based on significant differences in favour of insulin detemir in frequency of hypoglycaemia (Rate-Ratio = 0.52; CI = 0.44-0.61) and weight gain (Δ = 0.9 kg). Model outcomes were measured in Quality Adjusted Life Years (QALYs) using published utility estimates. Acquisition costs for insulin and direct healthcare costs associated with non-severe hypoglycaemic events were obtained from National Health Service public sources. One-way and probabilistic sensitivity analyses were performed. Based on lower incidence of non-severe hypoglycaemic events and less weight gain, the QALY gain from initiating treatment with insulin detemir compared with NPH insulin was 0.01 per patient per year. Incremental cost-effectiveness ratios for the individual countries were: Denmark, Danish Kroner 170,852 (€22,933); Finland, €28,349; Norway, Norwegian Kroner 169,789 (€21,768); and Sweden, Swedish Krona 226,622 (€25,097) per QALY gained. Possible limitations of the study are that data on hypoglycaemia and relative weight benefits from a clinical trial were combined with hypoglycaemia incidence data from observational studies. These populations may have slightly different patient characteristics. The lower risk of non-severe hypoglycaemia and less weight gain associated with using insulin detemir compared with NPH insulin when initiating insulin treatment in insulin naïve patients with type 2 diabetes provide economic benefits in the short-term. Based on cost/QALY threshold values, this represents good value for money in the Nordic countries. Using a short-term modelling approach may be conservative, as reduced frequency of hypoglycaemia and less weight gain may also have positive long-term health-related implications.

Data on dietary intake and physical activity has been collected from a representative sample of the Danish population from 2003-2008. The aim of the present study was to describe the habitual diet in Denmark and to evaluate the overall diet quality using a diet quality index based on the National Food-Based Dietary Guidelines (FBDG), which consists of seven guidelines regarding diet and one regarding physical activity. Data from the Danish National Survey of Diet and Physical Activity 2003-2008 (n=3354) were included. The diet quality index was constructed based on five of the seven dietary guidelines. Individuals were categorised according to quartiles of the diet quality index, and food and nutrient intakes were estimated in each of the groups. Macronutrient distribution did not meet recommendations in any of the groups, as energy from total fat and especially saturated fat was too high. A high intake of high-fat milk products, fat on bread and processed meat contributed to a high intake of total fat and saturated fat, and sugar-sweetened soft drinks contributed to a high intake of added sugars in the group below the lowest quartile of the diet quality index. Individuals above in the highest quartile had higher intakes of 'healthy foods' such as fish, fruit and vegetables, rye bread, and also a higher consumption of water and wine. Overall, intakes of micronutrients were sufficient in all groups. The diet quality index is a useful tool in assessing food and nutrient intake in individuals with high vs. low degree of compliance towards the dietary guidelines, and provides a valuable tool in future studies investigating variations in dietary intakes with respect to lifestyle, demographic and regional differences in Denmark.

The aim was to investigate ethnic differences in daily smoking in Malmö, Sweden, and whether these differences could be explained by psychosocial and economic conditions. The public health survey in Malmö 1994 is a cross-sectional study. A total of 5,600 individuals aged 20-80 years were randomly chosen to respond to a postal questionnaire. The participation rate was 71%. The study population was divided into seven categories according to country of birth; Sweden, Denmark/Norway, other Western countries, former Yugoslavia, Poland, Arabic-speaking countries and all other countries. A multivariate analysis was performed using a logistic regression model in order to investigate the importance of possible confounders on the ethnic differences in daily smoking. Finally, variables measuring social network, social support and economic conditions were introduced. The prevalence of daily smoking was significantly higher among both men and women born in Denmark/Norway (39.1% and 37.0%), men born in other Western countries (32.9%), Poland (34.0%) and Arabic-speaking countries (36.4%) than among Swedish men (21.7%) and women (23.8%). Women born in Arabic-speaking countries had a significantly lower smoking prevalence (7.1%). The multivariate analysis, including age, education and snuff, did not affect these results. A reduction of the odds ratio of daily smoking was observed for men born in Arabic-speaking countries and Poland after the introduction of the psychosocial and economic factors in the model. Only small changes were observed for women. There were significant ethnic group differences in daily smoking. Psychosocial and economic conditions in Sweden may be of importance in some ethnic groups.

To determine the impact of the European Union's Clinical Trials Directive on the number of academic drug trials carried out in Denmark. Retrospective review of applications for drug trials to the Danish Medicines Agency, 1993-2006. Applications for drug trials for alternate years were classified as academic or commercial trials. A random subset of academic trials was reviewed for number of participants in and intended monitoring of the trials. Academic and commercial drug trials showed an identical steady decline from 1993 to 2006 and no noticeable change after 2004 when good clinical practice became mandatory for academic trials. The Clinical Trials Directive introduced in May 2004 to ensure good clinical practice for academic drug trials was not associated with a decline in research activity in Denmark; presumably because good clinical practice units had already been in place in Danish universities since 1999. With such an infrastructure academic researchers can do drug trials under the same regulations as drug companies.

Previous studies have found that residents of deprived neighbourhoods have an increased risk of perceived stress compared to residents with similar sociodemographic and socioeconomic characteristics in non-deprived neighbourhoods. While stress may provide an explanatory pathway linking neighbourhood deprivation to health-risk behaviour, only limited research has been undertaken on whether perceived stress influences health-risk behaviour in deprived neighbourhoods. Moreover, it is uncertain whether perceived stress has a negative effect on the associations between socioeconomic status and health-risk behaviours in deprived neighbourhoods. The overall aim of this study was to compare perceived stress in deprived neighbourhood with that in the general population, and to examine whether perceived stress was associated with health-risk behaviours (including their co-occurrence) in deprived neighbourhoods. A further aim was to examine whether perceived stress modified the associations between socioeconomic status and health-risk behaviours. Four questions from the Perceived Stress Scale were used as indicators of perceived stress. Multiple logistic regression analyses were applied to cross-sectional data from 5113 adults living in 12 deprived neighbourhoods in Denmark. Data from 14,868 individuals from the nationally representative Danish Health and Morbidity Survey 2010 were used as a comparison group with regard to perceived stress. Residents of deprived neighbourhoods had higher odds of perceived stress than the general population. Associations between disposable income, economic deprivation, strain, and perceived stress were found in deprived neighbourhoods. Perceived stress was significantly associated with higher odds of health-risk behaviour, including a low intake of fruit or vegetables, daily smoking, physical inactivity, and the co-occurrence of health-risk behaviours, even after adjustment for demographic and socioeconomic characteristics. Perceived stress was more strongly associated with physical inactivity and having two or more health-risk behaviours among residents with medium/high socioeconomic status compared to residents with low socioeconomic status. Overall, the study showed a clear association between perceived stress and health-risk behaviour in deprived neighbourhoods. Future health promotion interventions targeting deprived neighbourhoods may benefit from incorporating stress reduction strategies to reduce health-risk behaviour. Further research is needed to fully understand the mechanism underlying the association between perceived stress and health-risk behaviour in deprived neighbourhoods.

To describe a method for identification, classification and assessment of maternal deaths in Denmark and to identify substandard care. Register study and case audit based on data from the Registers of the Danish Medical Health Board, death certificates and hospital records. Denmark 2002-2006. Women who died during a pregnancy or within 42 days after a pregnancy. Maternal deaths were identified by notification from maternity wards and data from the Danish National Board of Health. A national audit committee assessed hospital records of direct and indirect deaths. Maternal mortality ratio, causes of death and suboptimal care. In the study period, 26 women died during pregnancy or within 42 days from direct or indirect causes, leading to a maternal mortality ratio of 8.0/100,000 live births. Causes of death were cardiac disease, thromboembolism, hypertensive disorders of pregnancy, Streptococcus A infections, suicide, amniotic fluid embolism, cerebrovascular hemorrhage, asthma and diabetes. Our method proved valid and can be used for future research. Causes of death could be identified and learning points from the assessments could form the basis of focused education and guidelines. Future complementary 'near miss' studies and cooperation with other countries with comparable health systems are expected to improve the benefits of the enquiries, contributing to improved management of life-threatening conditions in pregnancy and childbirth.

High accessibility of unhealthy food stores may contribute to a poor dietary quality. Research on the link between neighbourhood food environment and consumption is limited, especially in a European context. The objective of this study was to examine the relationship between convenience stores (CS) and dietary quality within the Capital Region of Denmark. Cross-sectional study of the geographic food environment in the Capital Region of Denmark based on 47 623 subjects (age 16+ years) with complete information on retail food environment and dietary quality. A categorization procedure to identify CS from a government list of inspected food stores (the Smiley register) was developed. Using GIS network analyses, density of CS within 0.25 km and 0.5 km network buffers from residency was calculated for participants in metropolitan and non-metropolitan areas, respectively. Information on dietary intake and confounders is derived from a questionnaire survey. Multi-level analyses were performed, adjusting for age, sex, individual socio-economic factors and area socio-economic status. In the non-metropolitan population, the odds of having an unhealthy diet increased significantly (P < 0.0001) with increased density of CS. Compared to individuals who did not have a CS within 0.5 km from their home, the odds ratios were 1.20 (95% CI: 1.09-1.33) and 1.37 (95% CI: 1.19-1.57) for individuals having 1 or ≥2 CS, respectively. In the fully adjusted model, the overall association remained significant (P = 0.015) and odds ratios diminished to 1.14 (1.02-1.27) and 1.18 (1.01-1.38). High accessibility of CS in neighbourhoods is associated with less healthy dietary habits among residents. © The Author 2016.

Exposure to solar ultraviolet radiation is the main cause of skin cancer and may well present an occupational health and safety problem. In Denmark, skin cancer is a common disease in the general population, but detailed data on solar ultraviolet radiation exposure among outdoor workers are lacking. The aim of this study was to provide objective measurements of solar ultraviolet radiation exposure on working days and at leisure and compare levels of exposure between groups of mainly outdoor, equal-parts-outdoor-and-indoor and indoor workers. To this end, UV-B dosimeters with an aluminum gallium nitride (AlGaN) photodiode detector were used to measure the solar ultraviolet radiation exposure of 457 workers in the Danish summer season. Presented as semi-annual standard erythemal dose (SED) on working days, respectively, at leisure, the results are for mainly outdoor workers 214.2 SED and 64.8 SED, equal-parts-outdoor-and-indoor workers 131.4 SED and 64.8 SED, indoor workers 55.8 SED and 57.6 SED. The daily SED by month is significantly different (α = 0.05) between mainly outdoor, equal-parts-outdoor-and-indoor and indoor workers and across professional groups; some of which are exposed at very high levels that is roofers 361.8 SED. These findings substantiate that exposure to solar ultraviolet radiation is indeed an occupational health and safety problem in Denmark. © 2018 The Authors.

In 2006 WHO presented the infant and child growth charts suggested for universal application. However, major determinants for perinatal outcomes and postnatal growth are laid down during antenatal development. Accordingly, monitoring fetal growth in utero by ultrasonography is important both for clinical and scientific reasons. The currently used fetal growth references are derived mainly from North American and European population and may be inappropriate for international use, given possible variances in the growth rates of fetuses from different ethnic population groups. WHO has, therefore, made it a high priority to establish charts of optimal fetal growth that can be recommended worldwide. This is a multi-national study for the development of fetal growth standards for international application by assessing fetal growth in populations of different ethnic and geographic backgrounds. The study will select pregnant women of high-middle socioeconomic status with no obvious environmental constraints on growth (adequate nutritional status, non-smoking), and normal pregnancy history with no complications likely to affect fetal growth. The study will be conducted in centres from ten developing and industrialized countries: Argentina, Brazil, Democratic Republic of Congo, Denmark, Egypt, France, Germany, India, Norway, and Thailand. At each centre, 140 pregnant women will be recruited between 8 + 0 and 12 + 6 weeks of gestation. Subsequently, visits for fetal biometry will be scheduled at 14, 18, 24, 28, 32, 36, and 40 weeks (+/- 1 week) to be performed by trained ultrasonographers.The main outcome of the proposed study will be the development of fetal growth standards (either global or population specific) for international applications. The data from this study will be incorporated into obstetric practice and national health policies at country level in coordination with the activities presently conducted by WHO to implement the use of the Child Growth Standards.

2009-10-26

Pollen allergy currently affects a fifth of the population. A warmer climate will lead to a longer pollen season and more days with high pollen counts. In addition, a warmer climate increases the risk of proliferation of new plants with well-known allergenic pollens like ragweed, plane tree and wall pellitory, which have not previously caused allergy in Denmark. The consequences will be more people with hay fever and pollen asthma, longer allergy seasons and an increase in the severity of symptoms, disease-related costs and demands on health care for diagnosis and treatment of more complex allergies.

Objectives To examine risk of suicide among individuals with hospitalised chronic obstructive pulmonary disease (COPD) and to profile differences according to sex, age, psychiatric history, and recency and frequency of COPD hospitalisations. Design Nested case–control study. Setting Data were retrieved from Danish national registries. Participants All suicide cases aged 40–95 years deceased between 1981 and 2006 in Denmark (n=19 869) and up to 20 live population controls per case matched on sex and date of birth (n=321 867 controls). Main outcome measures The relative risk of suicide associated with COPD was computed using conditional logistic regression and adjusted for effects of psychiatric history and important sociodemographic factors. Results In our study population, 3% of suicide cases had been hospitalised for COPD compared with 1% of matched population controls. Thus, a hospitalised COPD was associated with a significantly increased risk for suicide (OR 2.6; 95% CI 2.3 to 2.8). The increased risk remained significant after adjustment for psychiatric history and sociodemographic variables (OR 2.0; 95% CI 1.8 to 2.2), and increased progressively with frequency and recency of COPD hospitalisation. At the same time, suicide risk associated with COPD differed significantly by sex, age and psychiatric status. The relative risk was more pronounced in women, in individuals older than 60 years and in persons with no history of psychiatric illness. Conclusions COPD confers an important risk factor for suicide completion. Risk assessment and prevention efforts should take patients’ sex, age and psychiatric history into consideration.

High-frequency fluctuations in Denmark Strait transport

NASA Astrophysics Data System (ADS)

Haine, T. W. N.

2010-07-01

Denmark Strait ocean current transport exhibits quasi-regular fluctuations immediately south of the sill with periods of 2-4 days. The transport variability is similar to the mean transport itself. Using a circulation model we explore prospects to monitor the fluctuations. The model has realistic transport and shows water leaving Denmark Strait in equivalent-barotropic cyclones that are nearly geostrophic and correlate with sea-surface height (SSH). Existing satellite altimeter observations of SSH have adequate space/time sampling to reconstruct the transport fluctuations using a regression developed from the model results, but measurement error overwhelms the signal. From the model results, the pending Surface Water and Ocean Topography (SWOT) wide-swath altimeter appears accurate enough, and with good-enough coverage, to allow the transport fluctuations to be reconstructed. Bottom pressure recorders at the exit of the Denmark Strait can also reproduce the transport variability.

Until 2000 Denmark was iodine deficient with moderate deficiency in the western part and mild deficiency in the eastern part. The occurrence of goitre and autonomous hyperthyroidism was high, and pregnancy was associated with a reduction in thyroid function. After cautious mandatory iodization of household salt and salt used for bread production, the iodine intake in Denmark is now low normal. The DanThyr monitoring has shown a transient increase in hyperthyroidism followed by a decrease, and goitre is becoming less common. Hypothyroidism has become more common, and this has to be followed.

It is not known which sports are most likely to cause overuse injuries of the extremities in children. In this study, we report on the incidence of overuse injuries of the upper and lower extremities in children who participate in various leisure-time sports and relate this to the frequency of sport sessions. Natural experiment including a prospective cohort study. 10 state schools in 1 Danish municipality: Svendborg. 1270 children aged 6-13 years participating in the Childhood Health, Activity, and Motor Performance School Study Denmark. Over 2.5 years, parents answered weekly SMS-track messages (a) on type and frequency of leisure-time sports undertaken by their child, and (b) reporting if their child had experienced any musculoskeletal pain. Children with reported pain were examined by a clinician and diagnosed as having an overuse injury of an extremity or not. The incidence of diagnosed overuse injury was calculated for each of the 9 most common sports in relation to 5-week periods. Incidence by frequency of sessions was calculated, and multivariable analysis was performed taking into account age, sex and frequency of physical education classes at school. Incidence of overuse injuries of the lower extremity ranged from 0.2 to 3.3 for the 9 sports, but was near 0 for overuse injuries of the upper extremities. There was no obvious dose-response. The multivariate analysis showed soccer and handball to be the sports most likely to result in an overuse injury. Among a general population of schoolchildren, overuse injuries of the lower extremities were not common and overuse injuries of the upper extremities were rare. Organised leisure-time sport, as practised in Denmark, can be considered a safe activity for children. Published by the BMJ Publishing Group Limited.

Childbearing at extremely advanced maternal age is a globally increasing trend, but only a few studies have described the outcomes of these pregnancies. The aim of this study was to describe the occurrence of childbearing at age 50 and up in the Nordic countries, as well as to examine the frequency of adverse obstetric and neonatal outcomes. A descriptive population-based study was designed. Data from 1991 to 2013 were collected from the Medical Birth Registries in Denmark, Finland, Norway and Sweden. We investigated the occurrence of antepartum, delivery and neonatal outcomes. A total of 170 deliveries, in 141 singleton and 29 multiple pregnancies, were identified in mothers aged 50 and up. The highest frequency during this period was 6 per 100,000 deliveries. The prevalence for selected adverse outcomes in singleton pregnancies were: intrauterine fetal death (IUFD) 6%, preeclampsia 4%, preterm delivery 14%, gestational diabetes 8% and cesarean delivery 50%. In multiple pregnancies, the respective prevalence were: IUFD 2%, preeclampsia 22%, preterm delivery 57%, gestational diabetes 10% and cesarean delivery 79%. Pregnancy after assisted reproductive technologies was frequent (29% of singleton and 50% of multiple pregnancies). This study found high frequency of obstetric and neonatal complications at extremely advanced maternal age. Despite a high prevalence of stillbirth in singleton pregnancies in the studied Nordic countries, other complications were less frequent than those previously reported in different populations. Adequate preconception consultation concerning maternal and neonatal hazards is highly recommended in this group of women. Copyright © 2018. Published by Elsevier B.V.

Quality of life among children in the Nordic countries.

Lindström, B; Eriksson, B

1993-02-01

Quality of life (QOL) is a concept with no generally accepted definition. Most clinical studies have had an individual approach where demographic and socio-economic population aspects have not been considered. QOL has hardly ever been used in studies of children. In this study QOL is defined as the essential resources of a child population, expressed in external, inter-personal and personal conditions. Both objective conditions and the corresponding subjective perceptions are included. A model for an empirical application is demonstrated on a random sample of 15,000 children in the five Nordic countries. The data were collected in a questionnaire mailed to the families of the children. The QOL was analysed in a normative way, where a base value was defined for each variable and the conditions of the children were compared to a Nordic standard for children's QOL. The results showed that children in the Nordic countries have a high QOL. The differences between the countries were rather small. Children in Sweden had the highest QOL, closely followed by children in Denmark and Norway, while children in Finland were in an intermediate position and the Icelandic children had the lowest QOL, mainly due to a lower level of satisfaction. This study can be considered as a base line study which later can be used in studies of time trends or in comparisons of groups of children such as children with special needs.

Objectives It is not known which sports are most likely to cause overuse injuries of the extremities in children. In this study, we report on the incidence of overuse injuries of the upper and lower extremities in children who participate in various leisure-time sports and relate this to the frequency of sport sessions. Design Natural experiment including a prospective cohort study. Setting 10 state schools in 1 Danish municipality: Svendborg. Participants 1270 children aged 6–13 years participating in the Childhood Health, Activity, and Motor Performance School Study Denmark. Outcomes measures Over 2.5 years, parents answered weekly SMS-track messages (a) on type and frequency of leisure-time sports undertaken by their child, and (b) reporting if their child had experienced any musculoskeletal pain. Children with reported pain were examined by a clinician and diagnosed as having an overuse injury of an extremity or not. The incidence of diagnosed overuse injury was calculated for each of the 9 most common sports in relation to 5-week periods. Incidence by frequency of sessions was calculated, and multivariable analysis was performed taking into account age, sex and frequency of physical education classes at school. Results Incidence of overuse injuries of the lower extremity ranged from 0.2 to 3.3 for the 9 sports, but was near 0 for overuse injuries of the upper extremities. There was no obvious dose–response. The multivariate analysis showed soccer and handball to be the sports most likely to result in an overuse injury. Conclusions Among a general population of schoolchildren, overuse injuries of the lower extremities were not common and overuse injuries of the upper extremities were rare. Organised leisure-time sport, as practised in Denmark, can be considered a safe activity for children. PMID:28087543

Infections may trigger acute cardiovascular events, but the risk after community-acquired bacteremia is unknown. We assessed the risk for acute myocardial infarction and ischemic stroke within 1 year of community-acquired bacteremia. This population-based cohort study was conducted in Northern Denmark. We included 4389 hospitalized medical patients with positive blood cultures obtained on the day of admission. Patients hospitalized with bacteremia were matched with up to 10 general population controls and up to 5 acutely admitted nonbacteremic controls, matched on age, sex, and calendar time. All incident events of myocardial infarction and stroke during the following 365 days were ascertained from population-based healthcare databases. Multivariable regression analyses were used to assess relative risks with 95% confidence intervals (CIs) for myocardial infarction and stroke among bacteremia patients and their controls. The risk for myocardial infarction or stroke was greatly increased within 30 days of community-acquired bacteremia: 3.6% versus 0.2% among population controls (adjusted relative risk, 20.86; 95% CI, 15.38-28.29) and 1.7% among hospitalized controls (adjusted relative risk, 2.18; 95% CI, 1.80-2.65). The risks for myocardial infarction or stroke remained modestly increased from 31 to 180 days after bacteremia in comparison with population controls (adjusted hazard ratio, 1.64; 95% CI, 1.18-2.27), but not versus hospitalized controls (adjusted hazard ratio, 0.95; 95% CI, 0.69-1.32). No differences in cardiovascular risk were seen after >6 months. Increased 30-day risks were consistently found for a variety of etiologic agents and infectious foci. Community-acquired bacteremia is associated with increased short-term risk of myocardial infarction and stroke.

In Denmark it is permitted to draw overhead lines across residential areas. In connection with a Danish case-control study we developed a method for estimating the historical values of magnetic fields at residences. The study included 1,707 cases with childhood cancer and 4,788 matched population controls. A total of 16,082 different addresses had been occupied by the families from the time of conception until the date of diagnosis. The values of the extreme, maximum, middle and minimum 50 Hz magnetic field strengths originating from a 50-400 kV high-voltage installation were estimated for each of the dwellings included in a potential exposure area. 30 children were exposed to an average level of magnetic fields of 0.1 microT or more. The evaluated Danish method of exposure assessment was compared with the method for residential wiring codes developed by Wertheimer and Leeper /1/. We concluded that the US wiring codes are inappropriate for use in connection with the Danish electricity transmission system.

Abstract—Global renewable energy have maintained a steady growth in recent years under the support of national policies and energy demand. Resource distribution, land supply, economy, voltage class and other relevant conditions affect the renewable energy distribution and development mode. Therefore, is necessary to analyze the spatial-temporal distribution and development modes for renewable energy, so as to provide reference and guidance for the renewable energy development around world. Firstly, the definitions and influence factors the renewable energy development mode are compared and summarized. Secondly, the renewable energy spatial-temporal distribution in Germany and Denmark are provided. Wind and solar power installations account for the largest proportion of all renewable energy in Germany and Denmark. Finally, renewable energy development modes are studied. The distributed photovoltaic generation accounts for more than 95%, and distributed wind power generation installations account for over 85% in Germany. Solar and wind resources are developed with distributed development mode, in which distributed wind power installation accounts for over 75%.

Several studies have attempted to define the role of parental age in determining the prevalence of 47, +21 according to the origin of nondisjunction. This report analyzes the original data of 197 informative families from Italy and reviews the available literature (96 families from Denmark and 201 from other countries). Mothers whose gametes showed nondisjunction are treated as cases, and those with normal meiosis as controls within each study. To utilize the data fully, maternal age at birth of a 47, +21 individual is treated as a continuous variable in a nonparametric comparison. The combined evidence indicates that nondisjunction in the female is associated with a significant age difference between cases and controls which is mostly due to errors in the second meiotic division. It may be inferred that in the general population, aging enhances nondisjunction at both first and second division in the female, while aging in the male is presumably associated mostly (or only) with first division errors. Implications and alternative models are discussed.

Actinotignum schaalii (former named Actinobaculum schaalii) can cause urinary tract infections (UTIs) and bacteraemia, mainly in the elderly. A. schaalii is difficult to identify with conventional biochemical tests, and it is often overlooked if the urine is only cultured in ambient air. The aim of this study was to validate data from the nationwide Danish microbiology database (MiBa) with data from the laboratory information system (LIS) at the local department of microbiology in Viborg-Herning, and to evaluate the incidence rate of bacteraemia caused by A. schaalii in Denmark by using data from the MiBa. All departments of microbiology in Denmark report data to the MiBa. All microbiological samples with A. schaalii in Denmark were extracted for a period of 5 years from the MiBa and from the local LISs. All data obtained from our local LIS were also found in the MiBa, except for data on real-time PCR, which were not registered, owing to missing ID codes in the MiBa. From 2010 to 2014, there was a significant increase in the incidence rate of blood cultures with A. schaalii, from 1.8 to 6.8 cases per million, which was probably due to coincident implementation of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) in routine diagnostics. We found that A. schaalii caused bacteraemia and UTIs mainly in the elderly. In conclusion, the MiBa can be a useful source of nationwide microbiological data in Denmark. Our results suggest that the incidence rate of A. schaalii as a cause of bacteraemia has been underestimated, and that culture of urine in CO2 can improve the detection of A. schaalii.

2013-07-01

Although Scandinavian neuroscience has a proud history, its status during the Nazi era has been overlooked. In fact, prominent neuroscientists in German-occupied Denmark and Norway, as well as in neutral Sweden, were directly affected. Mogens Fog, Poul Thygesen (Denmark) and Haakon Sæthre (Norway) were resistance fighters, tortured by the Gestapo: Thygesen was imprisoned in concentration camps and Sæthre executed. Jan Jansen (Norway), another neuroscientist resistor, escaped to Sweden, returning under disguise to continue fighting. Fritz Buchthal (Denmark) was one of almost 8000 Jews escaping deportation by fleeing from Copenhagen to Sweden. In contrast, Carl Værnet (Denmark) became a collaborator, conducting inhuman experiments in Buchenwald concentration camp, and Herman Lundborg (Sweden) and Thorleif Østrem (Norway) advanced racial hygiene in order to maintain the "superior genetic pool of the Nordic race." Compared to other Nazi-occupied countries, there was a high ratio of resistance fighters to collaborators and victims among the neuroscientists in Scandinavia.

Inuit populations have lower levels of cardiometabolic risk factors for the same level of body mass index (BMI) or waist circumference (WC) compared to Europeans in cross-sectional studies. We aimed to compare the longitudinal associations of anthropometric measures with cardiovascular disease (CVD) and all-cause mortality in Inuit and Europeans. Using pooled data from three population-based studies in Canada, Greenland and Denmark, we conducted a cohort study of 10,033 adult participants (765 Nunavik Inuit, 2960 Greenlandic Inuit and 6308 Europeans). Anthropometric measures collected at baseline included: BMI, WC, waist-to-hip-ratio (WHR), waist-to-height-ratio (WHtR) and a body shape index (ABSI). Information on CVD and death was retrieved from national registers or medical files. Poisson regression analyses were used to calculate incidence rates for CVD and all-cause mortality. During a median follow-up of 10.5 years, there were 642 CVD events and 594 deaths. Slightly higher absolute incidence rates of CVD for a given anthropometric measure were found in Nunavik Inuit compared with Greenlandic Inuit and the Europeans; however, no cohort interactions were observed. For all-cause mortality, all anthropometric measures were positively associated in the Europeans, but only ABSI in the two Inuit populations. In contrast, BMI and WC were inversely associated with mortality in the two Inuit populations. Inuit and Europeans have different absolute incidences of CVD and all-cause mortality, but the trends in the associations with the anthropometric measures only differ for all-cause mortality. Previous findings of a lower obesity-associated cardiometabolic risk among Inuit were not confirmed. Copyright © 2017 Elsevier B.V. All rights reserved.

Although up to 80% of women can return to work after treatment for breast cancer, maintaining an affiliation to the labour market may be a challenge, as shown by the fact that the risks for unemployment and early retirement are increased in the years after treatment of cancer. It is important to understand the work problems experienced by cancer survivors, including their ability to work. The aim of this study was to determine whether the ability of long-term breast cancer survivors to work was different from that of a cancer-free control group. In this population-based cross-sectional questionnaire study, 776 breast cancer survivors were matched with 1552 cancer-free women. Women with breast cancer diagnosed in 1997-2000 were identified in the Danish Cancer Registry, and the cancer-free controls were sampled from the Central Population Registry. Work ability was measured from a single question on the 'work ability index'. Furthermore, the questionnaire contained questions on socioeconomic factors, health-related factors and factors related to the workplace. The overall response rate was 57% (493 survivors and 830 controls). After exclusions, the study population consisted of 170 survivors and 391 controls. Women with a diagnosis of breast cancer who had survived at least five years and had returned to work reported significantly poorer work ability than cancer-free controls. In models with adjustment for socioeconomic factors, health-related factors and support at work, the factors most strongly associated with impaired work ability were low income, fatigue and little help and support from a supervisor. Our findings indicate that the work ability of long-term breast cancer survivors who are disease-free and back in work is impaired in comparison with that of cancer-free women.

The terrestrial export of dissolved organic matter (DOM) is associated with climate, vegetation and land use, and thus is under the influence of climatic variability and human interference with terrestrial ecosystems, their soils and hydrological cycles. We present a data-set including catchments from four areas covering the major climate and land use gradients within Europe: a forested boreal zone (Finland), a temperate agricultural area (Denmark), a wet and temperate mountain region in Wales, and a warm Mediterranean catchment draining into the Gulf of Lyon. In all study areas, DOC (dissolved organic carbon) was a major fraction of DOM, with much lower proportions of DON (dissolved organic nitrogen) and DOP (dissolved organic phosphorus). A south-north gradient with highest DOC concentrations and export in the northernmost catchments was recorded: DOC concentrations and loads were highest in Finland and lowest in France. These relationships indicate that DOC concentrations/export are controlled by several factors including wetland and forest cover, precipitation and hydrological processes. DON concentrations and loads were highest in the Danish catchments and lowest in the French catchments. In Wales and Finland, DON concentrations increased with the increasing proportion of agricultural land in the catchment, whereas in Denmark and France no such relationship was found. DOP concentrations and loads were low compared to DOC and DON. The highest DOP concentrations and loads were recorded in catchments with a high extent of agricultural land, large urban areas or a high population density, reflecting the influence of human impact on DOP loads.

Yersinia ruckeri is a pathogen that has an impact on aquaculture worldwide. The disease caused by this bacterial species, yersiniosis or redmouth disease, generates substantial economic losses due to the associated mortality and veterinary costs. For predicting outbreaks and improving control strategies, it is important to characterize the population structure of the bacteria. The phenotypic and genetic homogeneities described previously indicate a clonal population structure as observed in other fish bacteria. In this study, the pulsed-field gel electrophoresis (PFGE) and multi locus sequence typing (MLST) methods were used to describe a population of isolates from outbreaks on French fish farms. For the PFGE analysis, two enzymes (NotI and AscI) were used separately and together. Results from combining the enzymes showed the great homogeneity of the outbreak population with a similarity > 80.0% but a high variability within the cluster (cut-off value = 80.0%) with a total of 43 pulsotypes described and an index of diversity = 0.93. The dominant pulsotypes described with NotI (PtN4 and PtN7) have already been described in other European countries (Finland, Germany, Denmark, Spain and Italy). The MLST approach showed two dominant sequence types (ST31 and ST36), an epidemic structure of the French Y. ruckeri population and a preferentially clonal evolution for rainbow trout isolates. Our results point to multiple types of selection pressure on the Y. ruckeri population attributable to geographical origin, ecological niche specialization and movements of farmed fish.

KANGERLUSSUAQ, GREENLAND—This small town in central western Greenland, which has a population of about 650 and a major airstrip dating from World War II, is a center for scientific research and a starting point for scientists working in the region and on Greenland's ice sheet to study climate change and other issues. The town, just north of the Arctic Circle, sits at the edge of the 190-kilometer-long Kangerlussuaq Fjord and straddles the Qinnguata Kuussua River estuary, whose source water is the Russell Glacier, about 20 kilometers to the east. Between Kanger—as some refer to the town—and the glacier, some Eskimo-Kalaallit elders held a traditional gathering last month and also offered their perspectives on climate change during an impromptu 14 July meeting with high school students and other visitors. The evening before that meeting, Ole Olsvig, Kurt Olsen, Avaruna Mathaeussen, and other high schoolers from Greenland were in a makeshift classroom at the back of a renovated former U.S. Army barracks in Kanger, which had served as a U.S. military base. The students, who said they care deeply about their traditional culture and also are very aware of recent changes in climate, were helping to make presentations about their summer science projects. A total of 16 high schoolers from Greenland, 3 from Denmark, and 5 from the United States were there, participating in Joint Science Education Project (JSEP) activities; JSEP is an international collaborative polar science education effort between Greenland, Denmark, and the United States that receives support from the U.S. National Science Foundation (NSF).

Fragmentation of terrestrial ecosystems has had detrimental effects on metapopulations of habitat specialists. Maculinea butterflies have been particularly affected because of their specialized lifecycles, requiring both specific food-plants and host-ants. However, the interaction between dispersal, effective population size, and long-term genetic erosion of these endangered butterflies remains unknown. Using non-destructive sampling, we investigated the genetic diversity of the last extant population of M. arion in Denmark, which experienced critically low numbers in the 1980s. Using nine microsatellite markers, we show that the population is genetically impoverished compared to nearby populations in Sweden, but less so than monitoring programs suggested. Ten additional short repeat microsatellites were used to reconstruct changes in genetic diversity and population structure over the last 77 years from museum specimens. We also tested amplification efficiency in such historical samples as a function of repeat length and sample age. Low population numbers in the 1980s did not affect genetic diversity, but considerable turnover of alleles has characterized this population throughout the time-span of our analysis. Our results suggest that M. arion is less sensitive to genetic erosion via population bottlenecks than previously thought, and that managing clusters of high quality habitat may be key for long-term conservation.

Objectives Maternal hyper- and hypothyroidism have been associated with increased risk of adverse pregnancy outcomes, but studies have led to inconsistent results. We aimed to identify children born to mothers with a hospital-recorded diagnosis of thyroid dysfunction in Denmark and to study the association with gestational age at delivery and birth weight of the child. Study Design Population-based cohort study using Danish nationwide registers. All singleton live births in Denmark between January 1, 1978 and December 31, 2006 were identified and stratified by maternal diagnosis of hyper- or hypothyroidism registered in the Danish National Hospital Register before January 1, 2007. Results Maternal first-time diagnosis of thyroid dysfunction before, during or after pregnancy was registered in 32,809 (2.0%) of the singleton live births (n = 1,638,338). Maternal diagnosis of hyperthyroidism (adjusted OR 1.22, 95% CI 1.15-1.30) and hypothyroidism (adjusted OR 1.17, 95% CI 1.08-1.27) were associated with increased risk of preterm birth. Moreover, birth weight in children born to mothers with a diagnosis of hyperthyroidism was lower (adjusted difference −51 g, 95% CI −58 to −43 g) and higher in relation to maternal hypothyroidism (adjusted difference 20 g, 95% CI 10-30 g). Hyperthyroidism was associated with small-for-gestational-age (adjusted OR 1.15, 95% CI 1.10-1.20) and hypothyroidism with large-for-gestational-age children (adjusted OR 1.24, 95% CI 1.17-1.31). Conclusions Based on Danish nationwide registers, both maternal hyper- and hypothyroidism were associated with increased risk of preterm birth. Actual birth weight of the child and birth weight for gestational age were low if the mother had a diagnosis of hyperthyroidism and high if the diagnosis was hypothyroidism. PMID:24783052

Type 1 diabetes requires extensive self-management to avoid complications and may have negative effects on the everyday life of people with the disease. The aim of this study was to compare adults with type 1 diabetes to the general population in terms of health-related quality of life, occupational status (level of employment, working hours and sick leave) and education level. 2415 adults (aged 18-98years) with type 1 diabetes were compared to 48,511 adults (aged 18-103years) from the general population. Data were obtained from two cross-sectional surveys conducted in 2010 and 2011 of adults living or treated in the Capital Region in Denmark. Differences between adults with type 1 diabetes and the general population were standardised for age and sex and analyzed using linear probability models and negative binomial regression. Differences were further analyzed in subgroups. Compared to the general population, adults with type 1 diabetes experienced lower health-related quality of life, were more frequently unemployed, had more sick leave per year and were slightly better educated. Differences in health-related quality of life and employment increased with age and were larger among women, as compared to men. No significant differences were found with regard to working hours. Our findings suggest that type 1 diabetes is associated with lower health-related quality of life, higher unemployment and additional sick leave. The negative association with type 1 diabetes is more pronounced in women and older adults. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Excess mortality from heart disease is observed in patients with severe mental disorder. This excess mortality may be rooted in adverse effects of pharmacological or psychotropic treatment, lifestyle factors, or inadequate somatic care. To examine whether persons with severe mental disorder, defined as persons admitted to a psychiatric hospital with bipolar affective disorder, schizoaffective disorder, or schizophrenia, are in contact with hospitals and undergoing invasive procedures for heart disease to the same degree as the nonpsychiatric general population, and to determine whether they have higher mortality rates of heart disease. A population-based cohort of 4.6 million persons born in Denmark was followed up from 1994 to 2007. Rates of mortality, somatic contacts, and invasive procedures were estimated by survival analysis. Incidence rate ratios of heart disease admissions and heart disease mortality as well as probability of invasive cardiac procedures. The incidence rate ratio of heart disease contacts in persons with severe mental disorder compared with the rate for the nonpsychiatric general population was only slightly increased, at 1.11 (95% confidence interval, 1.08-1.14). In contrast, their excess mortality rate ratio from heart disease was 2.90 (95% confidence interval, 2.71-3.10). Five years after the first contact for somatic heart disease, the risk of dying of heart disease was 8.26% for persons with severe mental disorder (aged <70 years) but only 2.86% in patients with heart disease who had never been admitted to a psychiatric hospital. The fraction undergoing invasive procedures within 5 years was reduced among patients with severe mental disorder as compared with the nonpsychiatric general population (7.04% vs 12.27%, respectively). Individuals with severe mental disorder had only negligible excess rates of contact for heart disease. Given their excess mortality from heart disease and lower rates of invasive procedures after first contact, it would seem that the treatment for heart disease offered to these individuals in Denmark is neither sufficiently efficient nor sufficiently intensive. This undertreatment may explain part of their excess mortality.

Background Prior studies have suggested that military service may be associated with the development of amyotrophic lateral sclerosis. We conducted a population-based case-control study in Denmark to assess whether occupation in the Danish military is associated with an increased risk of developing amyotrophic lateral sclerosis. Methods There were 3,650 incident cases of amyotrophic lateral sclerosis recorded in the Danish National Patient Registry between 1982 and 2009. Each case was matched to 100 age- and sex-matched population controls alive and free of amyotrophic lateral sclerosis on the date of the case diagnosis. Comprehensive occupational history was obtained from the Danish Pension Fund database, which began in 1964. Results 2.4% (n=8,922) of controls had a history of employment in the military prior to the index date. Military employees overall had an elevated rate of ALS (OR=1.3; 95% CI: 1.1-1.6). A ten-year increase in years employed by the military was associated with an odds ratio of 1.2 (95% CI: 1.0-1.4), and all quartiles of time employed were elevated. There was little suggestion of a pattern across calendar year of first employment, but there was some evidence that increasing age at first employment was associated with increased ALS rates. Rates were highest in the decade immediately following the end of employment (OR=1.6; 95% CI: 1.2-2.2). Conclusions In this large population-based case-control study, employment by the military is associated with increased rates of ALS. These findings are consistent with earlier findings that military service or employment may entail exposure to risk factors for ALS. PMID:26583610

Postal urine specimens: are they a feasible method for genital chlamydial infection screening?

BACKGROUND: A United Kingdom (UK) screening programme for Chlamydia trachomatis has recently been announced. Pilot projects involving the opportunistic testing of women attending health facilities are due to commence in several sites. There is a danger that this approach will fail to obtain adequate population coverage. The alternative--true systematic population screening--is generally assumed to be unfeasible. Studies in Denmark using postal urine specimens have challenged this assumption. No such studies have been reported from the UK. AIM: To assess the potential of urine specimens sent by post as the basis for a UK population screening strategy for genital chlamydial infection. METHOD: Two hundred patients (100 men, 100 women) aged 18 to 45 years were randomly sampled from the list of one urban group practice. Subjects were mailed an explanatory letter, a urine sample container, a sexual lifestyle questionnaire, and a prepaid return envelope. Non-responders were contacted by telephone; persistent non-responders were visited at home. Samples were tested for Chlamydia by DNA amplification and enzyme immunoassay. RESULTS: Sixty-four (32%) subjects were no longer living at their GP registered address. Of the remaining 136, 126 (93%) responded to the survey and 113 (83%) accepted the request for a urine sample and completed a questionnaire. Acceptance rates were similar for men and women and across age groups. Four samples (3%) were Chlamydia positive. CONCLUSION: Home mailed urine specimen collection in conjunction with a self-completed postal questionnaire is feasible. This could provide a viable basis both for determining population Chlamydia prevalence and for a UK Chlamydia population screening strategy. Overall cost effectiveness of such a strategy will depend on the cost of the test used. Comparative performance characteristics of the different currently available tests in this setting have yet to be fully determined. PMID:10562745

The purposes of this study were to measure the prevalence of clinical and radiographic hip osteoarthritis (OA) and first-time diagnosis of hip OA in consecutive patients presenting to chiropractic practices in Denmark and to report the components of the initial treatment rendered by the chiropractic practitioner. A total of 2000 patient records and 1000 radiographs were reviewed retrospectively in 20 chiropractic clinics throughout Denmark. Information obtained included patients' primary complaint, physical examination and radiographic findings of hip OA, and treatment. Subsequently, the 20 clinics participated in a prospective survey where they collected equivalent information over a 2-week period. Retrospective review of records revealed that 1.4% of patients in Danish chiropractic practice had signs of clinical hip OA. Of these, 59% demonstrated radiographic signs of hip OA. Prospective data collection revealed that 3.4% of new patients had signs of clinical hip OA. Fifty-four percent of these demonstrated radiographic signs of hip OA, and of these 70% were diagnosed as having OA of the hip for the first time. Initial treatment involved manual treatment and advice on over-the-counter pain medication and/or supplements. Of all 1000 retrospectively reviewed radiographs in patients 40 years or older, 19.2% demonstrated radiographic signs of hip OA. Osteoarthritis of the hip is diagnosed and managed in primary care chiropractic practice in Denmark; however, it is likely underdiagnosed. In those newly presenting to chiropractic practitioners, first-time diagnosis with clinical and radiographic signs of hip OA appears to be common.

This article discusses major themes in recent transcultural psychiatric research in the Nordic countries from 2008 to 2011: (a) epidemiological studies of migration, (b) indigenous populations, and (c) quality of psychiatric care for migrants. Over the past several decades, the populations of the Nordic countries, Denmark, Finland, Norway, and Sweden, which were relatively homogeneous, have become increasingly culturally diverse. Many migrants to Nordic countries have been exposed to extreme stress, such as threats of death and/or torture and other severe social adversities before, during, and after migration, with potential effects on their physical, mental, social, and spiritual health. Growing interest in transcultural issues is reflected in the level of scientific research and clinical activity in the field by Nordic physicians, psychologists, social scientists, demographers, medical anthropologists, as well as other clinicians and policy planners. Research includes work with migrants and indigenous minorities in the Nordic countries, as well as comparisons with mental health in postconflict countries. We conclude by suggesting future directions for transcultural psychiatry research and providing guidelines for the education and training of future clinicians in the Nordic countries.

This study assesses whether stroke mortality trends have been less favorable among lower than among higher socioeconomic groups. Longitudinal data on mortality by socioeconomic status were obtained for Finland, Norway, Denmark, Sweden, England/Wales, and Turin, Italy. Data covered the entire population or a representative sample. Stroke mortality rates were calculated for the period 1981-1995. Changes in stroke mortality rate ratios were analyzed using Poisson regression and compared with rate ratios in ischemic heat disease mortality. Trends in stroke mortality were generally as favorable among lower as among higher socioeconomic groups, such that socioeconomic disparities in stroke mortality persisted and remained of a similar magnitude in the 1990s as in the 1980s. In Norway, however, occupational disparities in stroke mortality significantly widened, and a nonsignificant increase was observed in some countries. In contrast, disparities in ischemic heart disease mortality widened throughout this period in most populations. Improvements in hypertension prevalence and treatment may have contributed to similar stroke mortality declines in all socioeconomic groups in most countries. Socioeconomic disparities in stroke mortality generally persisted and may have widened in some populations, which fact underlines the need to improve preventive and secondary care for stroke among the lower socioeconomic groups.

Fraxinus excelsior, common ash native to Europe, is threatened by a recently identified pathogenic fungus Chalara fraxinea, which causes extensive damage on ash trees across Europe. In Denmark, most stands are severely affected leaving many trees with dead crowns. However, single trees show notably fewer symptoms. In this study, the impact of the emerging infectious disease on native Danish ash trees is assessed by estimating presence of inherent resistance in natural populations. Disease symptoms were assessed from 2007 to 2009 at two different sites with grafted ramets of 39 selected clones representing native F. excelsior trees. A strong genetic variation in susceptibility to C. fraxinea infections was observed. No genetic or geographic structure can explain the differences, but strong genetic correlations to leaf senescence were observed. The results suggest that a small fraction of trees in the Danish population of ash possess substantial resistance against the damage. Though this fraction is probably too low to avoid population collapse in most natural or managed ash forests, the observed presence of putative resistance against the emerging infectious disease in natural stands is likely to be of evolutionary importance. This provides prospects of future maintenance of the species through natural or artificial selection in favour of remaining healthy individuals. PMID:20823903

GPR Use and Activities in Denmark

Academic work on GPR in Denmark is performed both by the Technical University of Denmark (DTU) and the University of Copenhagen (KU). The work at DTU includes development of antennas and systems, e.g. an airborne ice-sounder GPR system (POLARIS) that today is in frequent use for monitoring of ice thickness in Greenland. DTU often collaborates with ESA (European Space Agency) regarding electromagnetic development projects. At KU there is an ongoing work with GPR applied to water resources. The main objective is to study flux of water and matter across different hydrological domains. There are several recent publications from KU describing research for data analysis and modelling as well as hydro geophysical applications. Also the Geological Survey of Denmark and Greenland (GEUS) performs frequent geological mapping with GPR. There have been mainly two actors on the Danish commercial market for several years: FalkGeo and Ramboll. Falkgeo has been active for many years acquiring data for several different applications such as archeology, utilities and roads. Their equipment pool comprises both a multichannel Terravision system form GSSI and a 2D system from Mala Geoscience with a comprehensive range of antennas. Ramboll has performed GPR surveys for two decades mainly with 2D systems from GSSI. In recent years Ramboll has also obtained a system with RTA antennas from Mala Geoscience and a multichannel system from 3D-Radar. These systems have opened markets both for deeper geological mapping and for shallow mapping. The geological mapping with the Mala system has often been combined with resistivity imaging (CVES) and refraction seismic. The 3D system has been applied in airports and on road for mapping of layer thicknesses, delamination and for control of asphalt works. Other areas comprise bridge deck evaluation and utility mapping. Ramboll also acts as client advisor for BaneDanmark, a state owned company who operates and develops the Danish state railway network. For this Ramboll has written a guideline for application of GPR on BaneDanmark railways. There are no national guidelines or test sites in Denmark. The use of GPR on roads is very limited in Denmark compared to our neighboring countries. This is possibly due to conservatism in the industry and due to the fact that Denmark decided not to participate in a collaboration between some of our neighboring countries about preparation of guidelines for application of GPR on roads, the Mara Nord Project. An improvement in accuracy and more automatized routines for mapping of delamination and stripping would also widen the market for application of GPR in airports and on roads. International guidelines for application of GPR in several fields would also help to make authorities recognize it as a valid complement and alternative to other established methods. This abstract is a contribution to COST Action TU1208.

The primary purpose of this study was to investigate the effect of the place of early development in a sample of Danish male elite and youth handball and football players. The sample included 366 handball and football players from the elite Danish league in the season 2011-2012 and a comparison sample of youth players under the age of 12 from 2003, including 147,221 football and 26,290 handball players. Odds ratio analysis showed that both population size and density significantly affected the proportional number of youth players per community and the odds of athletes reaching an elite level in football and handball. The odds for youth player registrations in both handball and football increased in rural in contrast to urban communities. However, elite football players primarily came from communities of high density (>1000 pop./km(2)), whereas elite handball players primarily came from less densely populated communities (100 to <250 pop./km(2)). Furthermore, there seems to be a relation between representation of elite and talent clubs in different communities and the probability of becoming an elite player in both sports. The limited number of elite players in both sports from rural communities may be due to national talent development strategies that do not incorporate development support for clubs in rural areas. Additionally, the results of the study clearly suggest the need to include the youth player population to advance research findings in birthplace effect studies.

An association between nickel contact allergy and hand eczema has previously been demonstrated. In 1990, Denmark regulated the extent of nickel release in the ear-piercing process as well as nickel release from consumer products. This study aimed to evaluate the effect of the Danish nickel regulation by comparing the prevalence of concomitant nickel allergy and hand eczema observed in two repeated cross-sectional studies performed in the same general population in Copenhagen. In 1990 and 2006, 3881 18-69 year olds completed a postal questionnaire and were patch tested with nickel. Data were analysed by logistic regression analyses and associations were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). The prevalence of concomitant nickel contact allergy and a history of hand eczema decreased among 18-35-year-old women from 9.0% in 1990 to 2.1% in 2006 (P < 0.01). The association between nickel contact allergy and a history of hand eczema decreased in this age group between 1990 (OR = 3.63; CI = 1.33-9.96) and 2006 (OR = 0.65; CI = 0.29-1.46). Among older women, no significant changes were observed in the association between nickel contact allergy and hand eczema. Regulatory control of nickel exposure may have reduced the effect of nickel on hand eczema in the young female population.

Adaptive harvest management for the Svalbard population of Pink-Footed Geese: 2014 progress summary

During the summer of 2013 we computed an optimal harvest strategy for the 3-year period 2013 – 2015. The strategy suggested that the appropriate annual harvest quota is 15 thousand. The 1-year harvest strategy calculated to determine whether an emergency closure of the hunting season is required this year suggested an allowable harvest of 25.0 thousand; thus, a hunting-season closure is not warranted.  If the harvest quota of 15 thousand were met in the coming hunting season, the next population count would be expected to be 71.0 thousand.  If only the most recent 4-year mean harvest were realized (11.3 thousand), a population size of 74.8 thousand would be expected.  Simulations suggest that it will take approximately seven years at current harvest levels to reduce population size to the goal of 60 thousand.  However, it is possible that the extension of the forthcoming hunting season in Denmark could result in a total harvest approaching 15 thousand; in this case, simulations suggest it would only take about three years to reach the goal.

Patterns of natural mortality in stream-living brown trout (Salmo trutta)

We tested the hypothesis that lifetime mortality patterns and their corresponding rates and causal factors differ among populations of stream-living salmonids. To this end, we examined the lifetime mortality patterns of several successive cohorts of two stream-living brown trout (Salmo trutta) populations in Spain and Denmark. In the southern population, we observed a consistent two-phase pattern, in which mortality was negligible during the first half of the lifetime and severe during the rest of the lifetime. In contrast, the northern population demonstrated a three-phase pattern with an earlier phase varying from negligible to severe, followed by a second stage of weak mortality, and lastly by a third life stage of severe mortality. Despite substantial differences in the mortality patterns between the two populations, the combined effect of recruitment (as a proxy of the density-dependent processes occurring during the lifetime) and mean body mass (as a proxy of growth experienced by individuals in a given cohort) explained c. 89% of the total lifetime mortality rates across cohorts and populations. A comparison with other published data on populations of stream-living brown trout within its native range highlighted lifetime mortality patterns of one, two, three and four phases, but also suggested that common patterns may occur in populations that experience similar individual growth and population density. ?? 2011 Blackwell Publishing Ltd.

'Angels in nursing': images of nursing sisters in a Lutheran context in the nineteenth and twentieth centuries.

PubMed

Malchau, Susanne

2007-12-01

This article examines Catholic nursing orders in Denmark. In 1849, 300 years after the Reformation, freedom of worship was introduced in Lutheran Denmark. In 1856 the first Catholic nursing order in modern times settled in the country. Others followed, and in 1940 the nursing orders owned 17 general hospitals and had a share of 10% of the hospital beds in Denmark. The purpose of this article is to identify images in the public media text of these Catholic nursing orders in Denmark from 1856 to the present, and to deconstruct the existing angel image the nuns and sisters in nursing have obtained. The assumption is that the public image is an important indicator of how a profession is valued in society. Six images - three positive and three negative - are identified, and it is demonstrated that these images were closely connected to the nursing sisters' professional activities and confessional affiliation. Until the 1950s the image of nursing sisters as representing a counterculture in Lutheran Denmark persisted. This image was succeeded by one of professional nurses of high standards. The shift was caused by increased secularisation and the renewal of religious life, as a result of the Second Vatican Council in the 1960s.

Trends in poverty risks among people with and without limiting-longstanding illness by employment status in Sweden, Denmark, and the United Kingdom during the current economic recession – a comparative study

Background Previous studies have found higher employment rates and lower risk of relative poverty among people with chronic illness in the Nordic countries than in the rest of Europe. However, Nordic countries have not been immune to the general rise in poverty in many welfare states in recent decades. This study analysed the trends in poverty risks among a particularly vulnerable group in the labour market: people with limiting-longstanding illness (LLSI), examining the experience of those with and without employment, and compared to healthy people in employment in Sweden, Denmark and the United Kingdom. Methods Cross-sectional survey data from EU-SILC (European Union Statistics on Income and Living Conditions) on people aged 25–64 years in Sweden, Denmark and the United Kingdom (UK) were analysed between 2005 and 2010. Age-standardised rates of poverty risks (<60% of national median equalised disposable income) were calculated. Odds ratios (ORs) of poverty risks were estimated using logistic regression. Results In all three countries, non-employed people with LLSI had considerably higher prevalence of poverty risk than employed people with or without LLSI. Rates of poverty risk in the UK for non-employed people with LLSI were higher than in Sweden and Denmark. Over time, the rates of poverty risk for Swedish non-employed people with LLSI in 2005 (13.8% CI=9.7-17.8) had almost doubled by 2010 (26.5% CI=19.9-33.1). For both sexes, the inequalities in poverty risks between non-employed people with LLSI and healthy employed people were much higher in the UK than in Sweden and Denmark. Over time, however, the odds of poverty risk among British non-employed men and women with LLSI compared with their healthy employed counterparts declined. The opposite trend was seen for Swedish men: the odds of poverty risk for non-employed men with LLSI compared with healthy employed men increased from OR 2.8 (CIs=1.6-4.7) in 2005 to OR 5.3 (CIs=3.2-8.9) in 2010. Conclusions The increasing poverty risks among the non-employed people with LLSI in Sweden over time are of concern from a health equity perspective. The role of recent Swedish social policy changes should be further investigated. PMID:24093150

The association between socio-economic status (SES) and headache among adolescents is an understudied issue, and no study has examined whether such an association changes over time. The aim was to examine trends in socio-economic inequality in frequent headache among 11- to 15-year-olds in Denmark from 1991 to 2014, using occupational social class (OSC) as indicator of SES. The study applies data from the Danish part of the international Health Behaviour in School-aged Children (HBSC) study. HBSC includes nationally representative samples of 11-, 13- and 15-year-olds. This study combines data from seven data survey years from 1991 to 2014, participation rate 88.6%, n = 31,102. We report absolute inequality as per cent difference in frequent headache between high and low OSC and relative inequality as odds ratio for frequent headache by OSC. In the entire study population, 10.4% reported frequent headache. There was a significant increase in frequent headache from 8.0% in 1991 to 12.9% in 2014, test for trend, p < 0.0001. This increasing trend was significant in all OSCs. The prevalence of frequent headache was significantly higher in low than high OSC, OR = 1.50 (95% CI: 1.34-1.67). This socio-economic inequality in frequent headache was persistent from 1991 to 2014. There was a significant and persistent socio-economic inequality, i.e. increasing prevalence of frequent headache with decreasing OSC. The association between socio-economic position and headache did not significantly change over time, i.e. the statistical interaction between OSC and survey year was insignificant. The prevalence of frequent headache among adolescents increases with decreasing SES. This socio-economic inequality has been persistent among adolescents in Denmark from 1991 to 2014. Clinicians should be aware of this social inequality. © 2018 European Pain Federation - EFIC®.

To examine duration of sickness absence as a risk marker for future mortality by socio-economic position among all private sector employees in Denmark in 1998-2004. All residents in Denmark employed in the private sector receiving sickness absence compensation in 1998 were investigated in a prospective cohort study. 236 207 persons (38.2% women, 61.8% men, age range 18-65, mean age 37.8 years) alive on 1 January 2001 were included in the study. Mortality from 1 January 2001 to 31 December 2004 was assessed using national register data. Deaths in 1999 and 2000 were excluded to determine the status of sickness absence duration as an early risk marker. For analyses within occupational grades, data were available for a sub-population of 137 607 study participants. 3040 persons died during follow-up. The age-adjusted risk of future mortality increased by duration of sickness absence in a graded fashion among men and non-blue collar workers. Among women and blue collar workers, there was no association of mortality with duration of sickness absences below 6 weeks. However, employees with > or =6 weeks of absence compared to those with 1-week absence had a substantial excess risk of death in all groups: adjusted hazard ratio 2.2 (95% CI 1.8 to 2.7) for women, 2.1 (95% CI 1.8 to 2.4) for men, 3.7 (95% CI 1.9 to 7.2) in white collar occupations, 3.3 (95% CI 2.2 to 5.0) in intermediate grade occupations and 2.0 (95% CI 1.7 to 2.3) in blue collar occupations. Administratively collected data on sickness absence compensation for periods > or =6 weeks identified "at risk" groups for future excess mortality in male and female private sector employees across occupational grade levels.

Delivering smart city system through experimental smart building concept. Design case of Nordhavn Community Centre, Denmark

It is an undisputed fact that the development of a city requires more energy to accommodate the needs of the city’s population. Greater energy consumption due to growing cities is a concern for scholars as well as governments all over the world. In the European Union, Denmark’s renewable energy policy provides tax exemptions for passive air conditioning and renewable energy sources to foster public participation. To meet its energy provision objectives under this condition, cities need instruments to reduce energy consumption. The building of a community centre in Nordhavn (Denmark) was chosen as such an instrument due to its flexibility and possible exposure to solar radiation as an endless source of energy. An experimental design for the building envelope was developed to test its thermal performance when including a thermal storage wall. Design research was conducted using 3D modelling. Testing was done on a simulation of the building made with the Ecotect software application to provide comparable results for thermal performance supported by qualitative-descriptive methods. It was concluded that including a thermal storage wall in the building model corresponds well with the objectives of the design. Based on the result of the test, in the context of, the thermal storage wall is capable of contributing to passive air conditioning.

The aim of this study was to investigate national prevalence, general demographic characteristics and survival of Danish patients with Ehlers-Danlos syndrome (EDS). A population-based cohort study was conducted using a database consisting of the entire Danish population alive at any given time between 1 January 2000 and 31 December 2012, based upon longitudinal Danish national registers. All patients with EDS were identified, and the cohort was described by disease prevalence, basic demographic characteristics, mean age at death and mortality for the observational period of 13 years. The cohort held 1427 unique persons with EDS, giving a national prevalence of 0.02%. The EDS population had a mean ( s . d .) age of 34.9 (18.6) years and comprised 73.9% females and 26.1% males. Of the cohort, 95.9% originated from Denmark and 57% were unmarried. We found that 31.6% of the cohort received state-granted subsidies, of which 77% were in the form of early retirement pension. Regarding educational status, 28.1% of the EDS cohort had completed primary education (⩽10th grade) as their highest educational level, while 71.9% had completed a higher level. During the observation period, 42 patients died, with a mean ( s . d .) age at death of 53.6 (21.7) years. This study confirmed a small national prevalence of patients diagnosed with EDS and showed that the majority of patients diagnosed are female. The EDS cohort had a lower educational level, mean age and life expectancy compared with the background population and showed a predisposition for receiving state-granted subsidies. © The Author 2017.

♦ BACKGROUND: The incidence of bacteremia and fungemia (BAF) is largely unknown in end-stage renal disease (ESRD) patients initiating peritoneal dialysis (PD). ♦ OBJECTIVE: The main objective was to estimate and compare incidence rates of first episodes of BAF in incident PD patients and a comparison cohort. A secondary objective was to compare causative agents and 30-day post-BAF mortality between PD patients and the comparison cohort. ♦ METHODS: Design: Observational cohort study. Central and North Denmark regions. patients who initiated PD during 1995 - 2010. For each patient we sampled up to 10 controls from the general population matched on age, sex, and municipality. ♦ MAIN OUTCOME: Data on positive blood cultures were retrieved from electronic microbiology databases covering the 2 regions. We calculated incidence rates (IRs) of first-time BAF for PD patients and population controls. Incidence-rate ratios (IRRs) were calculated to compare these rates. Thirty-day mortality was estimated by Kaplan-Meier analysis. ♦ RESULTS: Among 1,024 PD patients and 10,215 population controls, we identified 75 and 282 episodes of BAF, respectively. Incidence rates of BAF were 4.7 (95% confidence interval [CI], 3.8 - 5.9) per 100 person-years of follow-up (PYFU) in PD patients and 0.5 (95% CI, 0.4 - 0.5) per 100 PYFU in population controls (IRR = 10.4; 95% CI, 8.1 - 13.5). In PD patients, the most frequent microorganisms were Escherichia coli (18.7%) and Staphylococcus aureus (13.3%). Escherichia coli (27.3%) also ranked first among population controls. Thirty-day mortality following BAF was 20.8% (95% CI, 12.6 - 31.0) and 20.7% (95% CI, 16.3 - 25.9) among PD patients and population controls, respectively. ♦ CONCLUSIONS: Peritoneal dialysis patients are at markedly higher risk of BAF than population controls. Causative agents and the 30-day post-BAF mortality were similar in the 2 cohorts. Copyright © 2016 International Society for Peritoneal Dialysis.

To study incidence of radiation-related heart disease in a large population of breast cancer patients followed for up to 30 years. 72,134 women diagnosed with breast cancer in Denmark or Sweden during 1976-2006 and followed prospectively. Radiation-related risk was studied by comparing women with left-sided and right-sided tumours. 34,825 women (48%) received radiotherapy. Among unirradiated women tumour laterality had little relevance to heart disease. Among irradiated women mean dose to the whole heart was 6.3 Gy for left-sided tumours and 2.7 Gy for right-sided tumours. Mortality was similar in irradiated women with left-sided and right-sided tumours, but incidence ratios, left-sided versus right-sided, were raised: acute myocardial infarction 1.22 (95% CI 1.06-1.42), angina 1.25 (1.05-1.49), pericarditis 1.61 (1.06-2.43), valvular heart disease 1.54 (1.11-2.13). Incidence ratios for all heart disease were as high for women irradiated since 1990 (1.09 [1.00-1.19]) as for women irradiated during 1976-1989 (1.08 [0.99-1.17]), and were higher for women diagnosed with ischaemic heart disease prior to breast cancer than for other women (1.58 [1.19-2.10] versus 1.08 [1.01-1.15], p for difference=0.01). Breast cancer radiotherapy has, at least until recently, increased the risk of developing ischaemic heart disease, pericarditis and valvular disease. Women with ischaemic heart disease before breast cancer diagnosis may have incurred higher risks than others. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Preventing Introduction of Livestock Associated MRSA in a Pig Population – Benefits, Costs, and Knowledge Gaps from the Swedish Perspective

PubMed Central

Hæggman, Sara; Mieziewska, Kristina; Nilsson, Svante; Viske, Diana

2015-01-01

Antibiotic resistance is a growing concern in human, as well as in veterinary medicine. Part of the problem concerns how to respond to the risk presented by animal reservoirs of resistant bacteria with the potential of spreading to humans. One example is livestock associated methicillin-resistant Staphylococcus aureus (LA-MRSA). In countries where LA-MRSA is endemic in the pig population, people in contact with pigs have a higher risk of being colonised with LA-MRSA, and persons from this group are subjected to precautionary measures when visiting health care facilities. In the present study, it is assumed that, if LA-MRSA was introduced to the Swedish pig population, the prevalence in the risk groups would be the same as in Denmark or the Netherlands (two countries with low human prevalence that have implemented measures to detect, trace and isolate human LA-MRSA cases and, therefore, have comprehensive data with good coverage regarding prevalence of LA-MRSA), and that similar interventions would be taken in Swedish health care facilities. It is also assumed that the Swedish pig population is free of MRSA or that the prevalence is very low. We analyse if it would be efficient for Sweden to prevent its introduction by testing imported live breeding pigs. Given that quarantining and testing at import will prevent introduction to the pig population, the study shows that the preventive measures may indeed generate a societal net benefit. Benefits are estimated to be between € 870 720 and € 1 233 511, and costs to € 211 129. Still, due to gaps in knowledge, the results should be confirmed when more information become available.

The aim of the study was to assess the costs and outcome of ACT among 174 patients with severe and persistent mental illness in a rural area of Denmark. The study was based on a quasi-experimental design with a control group from the neighbouring region. Costs and retention in mental health services were analysed by using register data 1 year before and 4 years after inclusion in the study. Data on the use of supportive housing were available for the year before baseline and the subsequent 2 years only. Seventy eight percent of the patients receiving ACT were in contact with psychiatric services at the 4-year follow-up, while 69% of the patients in the control group had contact with psychiatric services (P < 0.17). Days in supportive housing were lower for the ACT group before baseline and remained so (dropping to zero) for the subsequent 2 years. Over 4 years, the mean total costs per patient in the group receiving ACT were DDK 493,442 (SE = 34,292). Excluding costs of supportive housing, the mean total costs per patient of the control group were DDK 537,218 (SE = 59,371), P < 0.53. If these costs are included, however, the mean total costs for the ACT group are unchanged, whereas costs for the control group rise to DDK 671,500 (SE = 73,671), P < 0.03. While ACT appears to have resulted in a significant reduction in costs for psychiatric hospitalizations, baseline differences in use of supportive housing make the effects of ACT on overall costs more ambiguous. At worst, however, overall costs did not increase. Given the generally acknowledged clinical benefits of ACT over standard outpatient care, the results support further dissemination of ACT in Denmark.

BACKGROUND. Allergens included in the European baseline series should result in positive patch test reactions in at least 1% of a patch test population. Inclusion of local anaesthetics other than benzocaine in the baseline series has previously been debated. To investigate temporal trends of benzocaine and lidocaine allergy in dermatitis patients who underwent routine patch testing in a tertiary referral patch test centre, and to clarify and discuss whether lidocaine and benzocaine should be included in routine series. Dermatitis patients who underwent routine patch testing with benzocaine as a part of the European baseline series between 1985 and 2010 (n = 19 347) and dermatitis patients who underwent routine patch testing with lidocaine between 1994 and 2001 (n = 6265) and between 2007 and 2009 (n = 1360) were included. The overall prevalences of contact allergy were 0.5% (benzocaine), 0.3% (lidocaine for the period 1994-2001), and 0.14% (lidocaine for the period 2007-2009). Current relevance was observed in 10% of those with benzocaine allergy and in 5% of those with lidocaine allergy. Benzocaine and lidocaine allergy is infrequent in Danish dermatitis patients. Lidocaine should only be used for aimed testing, and benzocaine should be removed from the baseline series used in Denmark. © 2011 John Wiley & Sons A/S.

The long-term mortality in children diagnosed with Haemophilus influenzae meningitis is poorly documented. We performed a nationwide, population-based cohort study including all Danish children diagnosed at the age between 0 and <5 years with H. influenzae meningitis from 1977 through 1996 and who were alive 1 year after diagnosis. Data were retrieved from medical databases in Denmark. For each H. influenzae meningitis patient, 6 age- and gender-matched population controls were indentified. We constructed Kaplan-Meier survival curves and used Cox regression analysis to estimate mortality rate ratios (MRR) and analyze causes of death. The risk of inpatient admission and of requiring hospital outpatient services during follow-up was calculated. We identified 1242 H. influenzae meningitis patients and 7452 population controls, with a median follow-up time of 21.3 years. The MRR for patients with H. influenzae meningitis was 1.08 (95% confidence interval, 0.57-2.05), adjusted MRR was 0.97 (95% confidence interval, 0.50-1.89). No increased mortality due to infections, respiratory diseases, or cancer was observed. The overall risk of inpatient admission and of requiring hospital outpatient services for the H. influenzae meningitis patients was increased the first 15 years of follow-up, mainly due to the nervous system diseases and ear diseases, thereafter the risk decreased to that of the population controls. In a developed country, children younger than 5 years surviving the acute phase of H. influenzae meningitis have no increased long-term mortality and only moderately increased morbidity.

Background Survivors of childhood cancer are at increased risk for a wide range of late effects. However, no large population-based studies have included the whole range of somatic diagnoses including subgroup diagnoses and all main types of childhood cancers. Therefore, we aimed to provide the most detailed overview of the long-term risk of hospitalisation in survivors of childhood cancer. Methods and findings From the national cancer registers of Denmark, Finland, Iceland, and Sweden, we identified 21,297 5-year survivors of childhood cancer diagnosed with cancer before the age of 20 years in the periods 1943–2008 in Denmark, 1971–2008 in Finland, 1955–2008 in Iceland, and 1958–2008 in Sweden. We randomly selected 152,231 population comparison individuals matched by age, sex, year, and country (or municipality in Sweden) from the national population registers. Using a cohort design, study participants were followed in the national hospital registers in Denmark, 1977–2010; Finland, 1975–2012; Iceland, 1999–2008; and Sweden, 1968–2009. Disease-specific hospitalisation rates in survivors and comparison individuals were used to calculate survivors’ standardised hospitalisation rate ratios (RRs), absolute excess risks (AERs), and standardised bed day ratios (SBDRs) based on length of stay in hospital. We adjusted for sex, age, and year by indirect standardisation. During 336,554 person-years of follow-up (mean: 16 years; range: 0–42 years), childhood cancer survivors experienced 21,325 first hospitalisations for diseases in one or more of 120 disease categories (cancer recurrence not included), when 10,999 were expected, yielding an overall RR of 1.94 (95% confidence interval [95% CI] 1.91–1.97). The AER was 3,068 (2,980–3,156) per 100,000 person-years, meaning that for each additional year of follow-up, an average of 3 of 100 survivors were hospitalised for a new excess disease beyond the background rates. Approximately 50% of the excess hospitalisations were for diseases of the nervous system (19.1% of all excess hospitalisations), endocrine system (11.1%), digestive organs (10.5%), and respiratory system (10.0%). Survivors of all types of childhood cancer were at increased, persistent risk for subsequent hospitalisation, the highest risks being those of survivors of neuroblastoma (RR: 2.6 [2.4–2.8]; n = 876), hepatic tumours (RR: 2.5 [2.0–3.1]; n = 92), central nervous system tumours (RR: 2.4 [2.3–2.5]; n = 6,175), and Hodgkin lymphoma (RR: 2.4 [2.3–2.5]; n = 2,027). Survivors spent on average five times as many days in hospital as comparison individuals (SBDR: 4.96 [4.94–4.98]; n = 422,218). The analyses of bed days in hospital included new primary cancers and recurrences. Of the total 422,218 days survivors spent in hospital, 47% (197,596 bed days) were for new primary cancers and recurrences. Our study is likely to underestimate the absolute overall disease burden experienced by survivors, as less severe late effects are missed if they are treated sufficiently in the outpatient setting or in the primary health care system. Conclusions Childhood cancer survivors were at increased long-term risk for diseases requiring inpatient treatment even decades after their initial cancer. Health care providers who do not work in the area of late effects, especially those in primary health care, should be aware of this highly challenged group of patients in order to avoid or postpone hospitalisations by prevention, early detection, and appropriate treatments.

Schizophrenia risk has been linked to urbanization, but the underlying mechanism remains unknown. Green space is hypothesized to positively influence mental health and might mediate risk of schizophrenia by mitigating noise and particle pollution exposure, stress relief, or other unknown mechanisms. The objectives for this study were to determine if green space are associated with schizophrenia risk, and if different measures of green space associate differently with risk. We used satellite data from the Landsat program to quantify green space in a new data set for Denmark at 30×30m resolution for the years 1985-2013. The effect of green space at different ages and within different distances from each person's place of residence on schizophrenia risk was estimated using Cox regression on a very large longitudinal population-based sample of the Danish population (943,027 persons). Living at the lowest amount of green space was associated with a 1.52-fold increased risk of developing schizophrenia compared to persons living at the highest level of green space. This association remained after adjusting for known risk factors for schizophrenia: urbanization, age, sex, and socioeconomic status. The strongest protective association was observed during the earliest childhood years and closest to place of residence. This is the first nationwide population-based study to demonstrate a protective association between green space during childhood and schizophrenia risk; suggesting limited green space as a novel environmental risk factor for schizophrenia. This study supports findings from other studies highlighting positive effects of exposure to natural environments for human health. Copyright © 2018 Elsevier B.V. All rights reserved.

The challenges of a possible exploitation of shale gas in Denmark

Extraction of shale gas has in recent years attracted increasing interest internationally and in Denmark. The potential areas for shale gas extraction from Alum shale in Denmark are defined as areas where Alum shale is at least 20 m thick, gas mature and buried at 1.5 to 7 km depth. Sweet Spots are areas where Alum shale potentially has a high utility value. Sweet Spots are identified and cover an area of approximately 6,800 km2 and are divided into two subareas; where the shale is at 1.5-5 km depth (2,400 km2) or at 5-7 km depth (4,400 km2). The shale in the upper depth interval has the greatest interest, as these areas are localized most accurate as the production from the deep interval is less costly. Many potential risks has been identified by exploitation of unconventional gas, of which groundwater contamination, waste management and radioactive substances are classified as the most important. The international literature reports a water demand with an average of about 18,000 m3 for older wells whereas newer fracking methods have less water usage. Based heron the estimated water consumption is between 20 million to 66 million m3 water in Danish shale gas production well and thus significantly in the total water budget. Consumption of water for shale gas will however be distributed over a number of years. The temporal development in water usage will depend on how quickly the gas wells are developed. The available groundwater resource in Denmark is estimated to about 1 billion m3 / year. Groundwater abstraction has been slightly falling the last decades and is now totally 700 million m3 / year. The use of surface water in Denmark is thus negligible. Although groundwater attraction is only 70 % of the available, the resource is overexploited in many areas due to water consumption is very unevenly distributed varying from region to region. The composition of potential hydraulic fracturing liquids in Denmark is at present unknown, but is expected to be selected from the same 14-40 different chemicals currently in use in Poland. In addition, the produced water may contain large amounts of formation brine expected to pose a significant problem for environmental safe discharge. Overall, this means that the fate of contaminants is very difficult to assess, but the infiltration of these substances into groundwater would likely result in a change of chemical conditions and an unacceptable deterioration of groundwater quality. Further, the average age of portable water in Denmark is high as the renewal time for groundwater is long. Hence, the spread and thus the dilution of contaminants will be very limited; these substances can be maintained in high concentrations in many areas. Consequently, a set of monitoring and remedial measures should be implemented to minimize possible environmental impacts, including baseline studies for the relevant inorganic and hazardous organic substances in surface water and groundwater known from previous studies to potentially have been affected by shale gas activities.

Objective Cardiopulmonary resuscitation (CPR) training in schools is recommended to increase bystander CPR and thereby survival of out-of-hospital cardiac arrest, but despite mandating legislation, low rates of implementation have been observed in several countries, including Denmark. The purpose of the study was to explore barriers to implementation of CPR training in Danish secondary schools. Design A qualitative study based on individual interviews and focus groups with school leadership and teachers. Thematic analysis was used to identify regular patterns of meaning both within and across the interviews. Setting 8 secondary schools in Denmark. Schools were selected using strategic sampling to reach maximum variation, including schools with/without recent experience in CPR training of students, public/private schools and schools near to and far from hospitals. Participants The study population comprised 25 participants, 9 school leadership members and 16 teachers. Results School leadership and teachers considered it important for implementation and sustainability of CPR training that teachers conduct CPR training of students. However, they preferred external instructors to train students, unless teachers acquired the CPR skills which they considered were needed. They considered CPR training to differ substantially from other teaching subjects because it is a matter of life and death, and they therefore believed extraordinary skills were required for conducting the training. This was mainly rooted in their insecurity about their own CPR skills. CPR training kits seemed to lower expectations of skill requirements to conduct CPR training, but only among those who were familiar with such kits. Conclusions To facilitate implementation of CPR training in schools, it is necessary to have clear guidelines regarding the required proficiency level to train students in CPR, to provide teachers with these skills, and to underscore that extensive skills are not required to provide CPR. Further, it is important to familiarise teachers with CPR training kits. PMID:27113236

Information on determinants of duration of untreated psychosis (DUP) is still needed to inform campaigns targeting people with first episode psychosis (FEP). This nation-wide study analysed the association between demographic factors (age, sex, ethnicity, marital status, and geographic area), premorbid and illness-related factors (global functional level, substance misuse, and contact to police), healthcare factors (referral source and first FEP contact) and DUP. The study population of 1266 patients aged 15-25years diagnosed with FEP (ICD10 F20.0-F20.99) was drawn from the Danish National Indicator Project during 2009-2011. The study population was combined with data from national administrative registers. A multinomial regression model was estimated to analyse the impact of demographic, premorbid and illness-related, and healthcare factors on DUP. One third of the population had a DUP below 6months. DUP longer than 12months was associated with older age at onset, being female, having cannabis misuse, and living in peripheral municipalities. Being charged by the criminal authorities during one year before FEP was associated with a DUP over 6months. DUP is related to a number of demographic, premorbid and healthcare factors. These findings suggest that future information campaigns should focus on increasing the awareness of early signs of psychosis not only among mental health professionals but also other professionals in contact with adolescents such as the police. It may also be useful to consider how to target information campaigns towards persons living in peripheral areas. Copyright © 2017 Elsevier B.V. All rights reserved.

To determine prevalence estimates of gynecological alarm symptoms in different age groups and to describe common patterns of gynecological symptoms. Web-based cross-sectional survey study. Nationwide in Denmark. A random sample of 51,090 women aged 20 years or above from the general population. An internet-based questionnaire study regarding the prevalence estimates of symptom experiences. A total of 18 symptoms of cervical, endometrial and ovarian cancer were selected through an extensive literature search, which included national and international guidelines. Prevalence estimates of self-reported experience of gynecological alarm symptoms within the preceding 4 weeks. A total of 26,466 women (54.5%) participated in the study. Some 80.3% had experienced at least one of the alarm symptoms within the preceding 4 weeks, and the median number of experienced symptoms was 2 (interquartile range 1-4). The most common symptoms were tiredness (53.0%) and abdominal bloating (36.7%); postmenopausal bleeding (2.3%) and involuntary weight loss (2.8%) were least frequent. Most of the symptoms were more prevalent among younger women, whereas only dyspnea and increased urgency of urination were more frequent among older women. Among younger women, multiple abdominal symptoms often occurred simultaneously and frequently in combination with pelvic pain, whereas older women were more likely to report single symptoms. Gynecological alarm symptoms are frequent in the general population, mostly among younger women. Older women reported fewer symptoms, and these often appeared as single symptoms. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

2006-02-01

Relative body weight is typically inversely associated with social status in affluent societies but studies comparing the social patterning of relative body weight and obesity in different countries have only seldom been conducted. The aim of this study was to analyse and compare the social patterning of relative weight and obesity by occupational status, educational attainment and marital status between Danish and Finnish women and men. Data from the Finnish Survey on Living Conditions and the Danish Health and Morbidity Survey, both collected in 1994, were compared. Relative weight was studied by using body mass index (BMI), and those with BMI > or =30 kg/m(2) were regarded as obese. Logistic regression analysis was used to examine the social patterning of obesity in the pooled dataset. Two-variable interaction effects were tested separately. Compared with their Danish counterparts, Finnish women and men had higher average relative weight and they were more often obese. There were no country differences in the socio-economic patterning of obesity by educational attainment, but a stronger patterning of obesity by occupational status was found among Danish women. Moreover, non-married women in Denmark were more likely to be obese than their married counterparts. Finns have higher relative weight and they are more often obese than Danes. The social patterning of obesity was similar in both studied countries but stronger in Denmark.

The aim of this study was to examine occurrence and consequences of diverticular disease in patients with Ehlers-Danlos syndrome (EDS) compared with a matched cohort. This nationwide population-based cohort study was conducted using data from medical registers in Denmark from year 2000 to 2012. The EDS cohort was identified using the specific diagnosis code for EDS and was randomly matched in a ratio of 1:20 by sex and date of birth (±1 year) with persons from the Danish general population. The occurrence of diverticular disease and the clinical characteristics of the initial diverticular event were compared between the EDS cohort and the comparison cohort. The first admission with diverticulitis was identified, and severity of diverticulitis, treatment, colonoscopies, length of stay, and 30-day mortality were investigated. We identified 1336 patients with EDS and matched a control cohort of 26,720 patients. The occurrence of diverticular disease in the EDS cohort (2.0 %) and the comparison cohort (0.68 %) differed significantly (p < 0.001). At the first diverticular event, the majority of patients were women (85 % for EDS and 87 % for the comparison cohort). Mean age, localization, and type of contact did not differ significantly. Admission with diverticulitis (1.0 % for EDS and 0.34 % for the comparison cohort) differed significantly (p < 0.001). We found no significant difference in severity of diverticulitis, treatment, length of stay, or 30-day mortality between the EDS and the comparison cohorts. Patients with EDS had an increased occurrence of overall diverticular events and admissions with diverticulitis compared with the general population.

Specialised palliative care (SPC) takes place in specialised services for patients with complex symptoms and problems. Little is known about what determines the admission of patients to SPC and whether there are differences in relation to institution type. The aims of the study were to investigate whether cancer patients' admittance to SPC in Denmark varied in relation to sex, age and diagnosis, and whether the patterns differed by type of institution (hospital-based palliative care team/unit, hospice, or both). This was a register-based study of adult patients living in Denmark who died from cancer in 2010-2012. Data sources were the Danish Palliative Care Database, Danish Register of Causes of Death and Danish Cancer Registry. The associations between the explanatory variables (sex, age, diagnosis) and admittance to SPC were investigated using logistic regression. In the study population (N = 44,548) the overall admittance proportion to SPC was 37%. Higher odds of overall admittance to SPC were found for women (OR = 1.23; 1.17-1.28), younger patients (<40 compared with 80+ years old) (OR = 6.44; 5.19-7.99) and patients with sarcoma, pancreatic and stomach cancers, whereas the lowest were for patients with haematological malignancies. The higher admission found for women was most pronounced for hospices compared to hospital-based palliative care teams/units, whereas higher admission of younger patients was more pronounced for hospital-based palliative care teams/units. Patients with brain cancer were more often admitted to hospices, whereas patients with prostate cancer were more often admitted to hospital-based palliative care teams/units. It is unlikely that the variations in relation to sex, age and cancer diagnoses can be fully explained by differences in need. Future research should investigate whether the groups having the lowest admittance to SPC receive sufficient palliative care elsewhere.

Economic assessment of climate adaptation options for urban drainage design in Odense, Denmark.

Zhou, Q; Halsnæs, K; Arnbjerg-Nielsen, K

2012-01-01

Climate change is likely to influence the water cycle by changing the precipitation patterns, in some cases leading to increased occurrences of precipitation extremes. Urban landscapes are vulnerable to such changes due to the concentrated population and socio-economic values in cities. Feasible adaptation requires better flood risk quantification and assessment of appropriate adaptation actions in term of costs and benefits. This paper presents an economic assessment of three prevailing climate adaptation options for urban drainage design in a Danish case study, Odense. A risk-based evaluation framework is used to give detailed insights of the physical and economic feasibilities of each option. Estimation of marginal benefits of adaptation options are carried out through a step-by-step cost-benefit analysis. The results are aimed at providing important information for decision making on how best to adapt to urban pluvial flooding due to climate impacts in cities.

Simulation studies showed that generic antiretroviral (ARV) drug utilization could lead to significant cost reduction of HIV treatment in developed world. This study aimed to quantify ARV utilization and costs in European countries between 2006 and 2015. We also assessed the impact of generic ARV drug utilization on cost reduction in real-life. ARV drug utilization in 14 European countries (France, Italy, Germany, Denmark, Netherlands, Norway, Sweden, Finland, Iceland, Croatia, Czech Republic, Estonia, Latvia, and Lithuania) were analysed using defined daily dose (DDD)/1000 inhabitants/year. ARV drug cost was estimated in million euro/year and euro/1000 inhabitants/year. The impact of generics on cost reduction was assessed in three countries: France, Denmark, and Czech Republic, using four parameters: expected savings, observed savings, brand price-reduction savings and overall savings. Between 2006 and 2015, median ARV drug utilization increased from 234 DDDs per 1000 inhabitants per year (IQR 124-388) to 385 (229-670). The median cost increased from €3751/1000 inhabitants/year (1109-4681) to €9158 (3269-10,646). Between 2013 and 2015, overall savings of €0.9, €1.6, and €33.7 million were respectively observed in Denmark, Czech Republic, and France. Overall savings observed in real-life from generic ARV drugs in Denmark were related to high rate of low-price generic utilization, contrarily to France and Czech Republic where these were more related to brand price-reduction than generic utilization itself.

Incidence and prevalence rates of personality disorders in Denmark-A register study.

PubMed

Pedersen, Liselotte; Simonsen, Erik

2014-11-01

Personality disorders (PDs) are prevalent in about one in every 10 adults. Prior to the introduction of the ICD-10 in Denmark, the incidence rate for PD (including schizotypal) among psychiatric patients was approximately 12% and the prevalence rate 14%. The aim of the present clinical epidemiology study is to investigate the use of ICD-10 PD as primary and secondary diagnoses in years 1995, 2000 and 2006, comorbid disorders and their relation to age and gender. The study includes all adult patients admitted to any psychiatric hospital (inpatients and outpatients) in Denmark. Both incidence and prevalence rates of PD diagnoses decrease over the study period. It is evident that all specific diagnoses significantly decrease or remain stable whereas the unspecified and mixed type significantly increases constituting up to 50% of diagnoses. Emotionally unstable PD stands out as the single most prevalent covering around one third of PD diagnoses. A decrease is found in the prevalence of patients receiving a PD diagnosis as a primary diagnosis, but an increase as a secondary diagnosis (most often as comorbid to depression or anxiety disorder). Differences are found in relation to gender and age. PDs are among the most prevalent disorders; however, rates are decreasing in psychiatric settings. There seem to be a rather huge gap between clinical evaluation and research data on prevalence of PDs. Clinicians need more education and sufficient time for in-depth personality assessment of PDs in all patient groups.

Preconception care is important for the screening, prevention and management of risk factors that affect pregnancy outcomes. We aimed to investigate pre-pregnancy care policies, guidelines, recommendations and services in six European countries. In 2013, an electronic search and investigation was undertaken of preconception policy, guidelines, recommendations and services available to healthcare professionals and the general public in six European countries: Belgium (Flanders), Denmark, Italy, the Netherlands, Sweden and the United Kingdom. Findings were compared within five categories: Governmental policy and legislation; Professional bodies and organisations; Healthcare providers; Charitable organisations; Web-based public information and internet sites. All countries had preconception recommendations for women with chronic diseases, such as diabetes and epilepsy. Recommendations for healthy women and men were fragmented and inconsistent. Preconception guidance was often included in antenatal and pregnancy guidelines. Differences between countries were seen with regard to nutritional and lifestyle advice particularly in relation to fish, caffeine and alcohol consumption, and vitamin supplementation. Current guidelines are heterogeneous. Collaborative research across Europe is required in order to develop evidence-based guidelines for preconception health and care. There is a need to establish a clear strategy for promoting advice and guidance within the European childbearing population.

Though about 20% of working age breast cancer survivors do not return to work after treatment, few studies have addressed risk factors for unemployment. The majority of studies on occupational consequences of breast cancer focus on non-employment, which is a mixture of sickness absence, unemployment, retirement pensions and other reasons for not working. Unemployment in combination with breast cancer may represent a particular challenge for these women. The aim of the present study is therefore to analyze the risk for unemployment in the years following diagnosis and treatment for breast cancer. This study included 14,750 women diagnosed with breast cancer in Denmark 2001-2009 identified through a population-based clinical database and linked with information from Danish administrative population based registers for information on labour market affiliation, socio-demography and co-morbid conditions. Multivariable analyses were performed by Cox's proportional hazard models. Two years after treatment, 81% of patients were still part of the work force, 10% of which were unemployed. Increasing duration of unemployment before breast cancer was associated with an adjusted HR = 4.37 (95% CI: 3.90-4.90) for unemployment after breast cancer. Other risk factors for unemployment included low socioeconomic status and demography, while adjuvant therapy did not increase the risk of unemployment. Duration of unemployment before breast cancer was the most important determinant of unemployment after breast cancer treatment. This allows identification of a particularly vulnerable group of patients in need of rehabilitation.

The road to success. Long-term prognosis for persons living with HIV in Denmark - time trends and risk factors.

PubMed

Lohse, Nicolai

2016-02-01

The work on this thesis began in 2003 when the global HIV epidemic was out of control. A minority of persons with HIV were benefitting fully from the recently introduced highly efficacious antiretroviral therapy (ART) combinations. Among the global challenges were lack of access to good healthcare, drug toxicity, and emergence of drug-resistant virus. It was unknown how long the drugs could maintain their efficacy in the individual even if administered as intended, and there was a fear that the increased drug pressure would increase the prevalence of drug resistance, subsequently leading to transmission of resistant virus from one individual to another, and thereby waning the treatment options available. Hence, we were far from the ideal conditions where an HIV-infected individual gets to know immediately that he/she is infected, has access to specialized medical and social support, receives a drug combination which effectively suppresses the virus and has no side effects, and is free of co-morbid conditions both before and after he/she gets infected. The nine papers on which this thesis is based each aimed to provide new knowledge to aspects of the above. Late diagnosis and late presentation to clinical care continue to be major barriers to improved HIV management. We used nation-wide hospital registries to explore the potential for an indicator disease-based HIV testing strategy. A range of conditions that were manifestations of the HIV infection itself were found to be associated with highly increased risk of HIV diagnosis during the coming year, but less so three to five years later. Other conditions were associated with an almost constant five-year long increased risk of being diagnosed with HIV because they share behavioural risk factors with HIV, making them indicators of not only current HIV but also of future HIV acquisition. Hence, indicator condition-based testing should be adapted to the local epidemic and could be a valuable addition to the existing detection practice. Once diagnosed, getting the full benefit of modern HIV care requires access to a good healthcare system. We compared temporal trends in quality and quantity of ART introduction in Den-mark and Greenland. Despite similar levels of health worker education and economic resources, ART implementation and mortality decline in Greenland lacked several years behind Denmark. The study reminded us that although economy may be a prerequisite for implementing an effective HIV care system, it is certainly not all it takes. The nationwide nature of the Danish HIV Cohort Study also allowed us to study a number of time trends at the population level. Despite what was feared, we found that the prevalence of triple-drug class virological failure (TCF) seemed to have stabilized after 2000; that the incidence rates of drug resistance acquisition were decreasing during 1999-2005; and that the prevalence of potential transmitters of drug-resistant HIV decreased during 1997-2004. We also looked at some of the consequences of virological failure and drug resistance and found that even modest levels of viraemia were associated with a high risk of future failure and death, and that in persons who have experienced TCF, the number and pattern of resistance mutations were independent predictors of death. Hence, despite the overall positive trends in virological failure and drug-resistance development at the population level, our findings underline the crucial importance of always having an effective treatment option available for the individual patient with drug-resistant virus. As mortality was declining for persons with access to ART and good HIV care, it became important to know how long persons with HIV could expect to live compared to the general population. We projected long-term survival and found that a 25-year old person with HIV and without hepatitis C virus (HCV) co-infection had a 50 per cent chance of surviving another 39 years, only 12.2 years less than a person in a matched general population cohort would survive. With improved survival and declining HIV-related co-morbidity, non-HIV related co-morbidity became a more visible contributor to the health status of persons with HIV. We assessed the impact of non-HIV related comorbidity acquired before the person became infected with HIV. We found that 32% of the observed mortality in our cohort was due to HCV and co-morbidities measured by the Charlson Comorbidity Index, 13% corresponded to the background mortality in the population, and that only 55% of the mortality could be attributed to HIV. Our findings confirmed that persons acquiring HIV differ at large from the general population, and that we should not expect overall mortality rates in populations with HIV to reach the levels in the general population. This thesis attempted to map some of the many challenges on the road towards increased survival of individuals and populations with HIV up to a level, which today in many settings is close to that of the general population. The studies in this thesis have each paid their modest contribution to show how crucially important it is to be diagnosed in time, to have access to a well-functioning health system, and to keep free of co-morbidity both before and after acquiring HIV. After many years of struggle and despair, and thanks to enormous advances in prevention and treatment, we are now looking towards a promising future.

Pedagogical competence and value clarification among health educators.

PubMed

Wistoft, Karen

2009-09-01

Individual and social values are increasingly important in health education. This article examines how health educators in Greenland and Denmark engage in value clarification as part of their educational practices. It presents the results of a study of health professionals in a variety of settings, focusing in particular on how development work and experimentation can strengthen their pedagogical competences. The study focuses on belief, reasoning, interpretation and reflection, rather than routines, skills, or ethical rules, and takes a participatory approach that oscillates between dialogical and qualitative empirical methodologies. It observes pedagogical practice in selected settings in Greenland and the municipality of Copenhagen. Within the framework provided by four discourses that appear to organize communication about health, it shows how values became important to the progress of two research-based development projects. On this basis, the article argues that health education can be effectively grounded in the values, perceptions, and experiences of a given population, while being guided by the health educators' biomedical knowledge and educational values.

The Scandinavian Fantasy: The Sources of Intergenerational Mobility in Denmark and the US

PubMed Central

Landersø, Rasmus; Heckman, James J.

2017-01-01

This paper examines the sources of differences in social mobility between the U.S. and Denmark. Measured by income mobility, Denmark is a more mobile society, but not when measured by educational mobility. There are pronounced nonlinearities in income and educational mobility in both countries. Greater Danish income mobility is largely a consequence of redistributional tax, transfer, and wage compression policies. While Danish social policies for children produce more favorable cognitive test scores for disadvantaged children, these do not translate into more favorable educational outcomes, partly because of disincentives to acquire education arising from the redistributional policies that increase income mobility.

Background and Aims Black cherry (Prunus serotina) is a North American tree that is rapidly invading European forests. This species was introduced first as an ornamental plant then it was massively planted by foresters in many countries but its origins and the process of invasion remain poorly documented. Based on a genetic survey of both native and invasive ranges, the invasion history of black cherry was investigated by identifying putative source populations and then assessing the importance of multiple introductions on the maintenance of gene diversity. Methods Genetic variability and structure of 23 populations from the invasive range and 22 populations from the native range were analysed using eight nuclear microsatellite loci and five chloroplast DNA regions. Key Results Chloroplast DNA diversity suggests there were multiple introductions from a single geographic region (the north-eastern United States). A low reduction of genetic diversity was observed in the invasive range for both nuclear and plastid genomes. High propagule pressure including both the size and number of introductions shaped the genetic structure in Europe and boosted genetic diversity. Populations from Denmark, The Netherlands, Belgium and Germany showed high genetic diversity and low differentiation among populations, supporting the hypothesis that numerous introduction events, including multiple individuals and exchanges between sites, have taken place during two centuries of plantation. Conclusions This study postulates that the invasive black cherry has originated from east of the Appalachian Mountains (mainly the Allegheny plateau) and its invasiveness in north-western Europe is mainly due to multiple introductions containing high numbers of individuals.

To estimate the occurrence of and risk factors associated with genital warts in Danish men We conducted a cross-sectional, questionnaire-based study among almost 23 000 men aged 18-45 years, randomly sampled from the general population of Denmark. Data was collected on self-reported clinically diagnosed genital warts, and various lifestyle habits. Ever having had clinically diagnosed genital warts was reported by 7.9% of the men. The median age at first occurrence was 22 years. Genital warts within the previous 12 months were reported by 0.92% of the men, with a peak of 1.83% among men aged 21-24 years. The likelihood of reporting genital warts was strongly correlated with the lifetime number of sex partners (OR 8.0; 95% CI 6.0 to 10.8 for ≥15 partners vs 1-2 partners). Other factors associated with an increased risk for genital warts included ever having smoked and having had other sexually transmitted infections. Almost 8% of Danish men aged 18-45 years reported having had a diagnosis of genital warts. The results provide baseline information for developing and monitoring prevention strategies against genital warts, such as vaccination against human papillomavirus types 6 and 11.

Human biomonitoring (HBM) is an important tool, increasingly used for measuring true levels of the body burdens of environmental chemicals in the general population. In Europe, a harmonized HBM program was needed to open the possibility to compare levels across borders. To explore the prospect of a harmonized European HBM project, DEMOCOPHES (DEMOnstration of a study to COordinate and Perform Human biomonitoring on a European Scale) was completed in 17 European countries. The basic measurements performed in all implemented countries of DEMOCOPHES included cadmium, cotinine and phthalate metabolites in urine and mercury in hair. In the Danish participants, significant correlationsmore » between mothers and children for mercury in hair and cotinine in urine were found. Mercury in hair was further significantly associated with intake of fish and area of residence. Cadmium was positively associated with BMI in mothers and an association between cadmium and cotinine was also found. As expected high cotinine levels were found in smoking mothers. For both mercury and cadmium significantly higher concentrations were found in the mothers compared to their children. In Denmark, the DEMOCOPHES project was co-financed by the Danish ministries of health, environment and food safety. The co-financing ministries agreed to finance a number of supplementary measurements of substances of current toxicological, public and regulatory interest. This also included blood sampling from the participants. The collected urine and blood samples were analyzed for a range of other persistent and non-persistent environmental chemicals as well as two biomarkers of effect. The variety of supplementary measurements gives the researchers further information on the exposure status of the participants and creates a basis for valuable knowledge on the pattern of exposure to various chemicals. - Highlights: • Levels of cadmium, mercury and cotinine in the Danish subpopulation are comparable to levels in the total DEMOCOPHES population with mercury in hair above the European median. • Supplementary sample collection and measurements in Denmark gave valuable exposure information on a variety of other chemicals of current toxicological, public and regulatory interest, such as persistent organic pollutants. • It is highly valuable to obtain as much exposure information as possible once you have established the study cohort.« less

The main purpose of this nationwide follow-up study was to examine the development of self-reported lymphedema in the population of women with early-stage breast cancer in Denmark. In 2008 and 2012 two identical questionnaires were sent to the women aged 18-70 years treated for unilateral primary breast cancer in 2005 and 2006. 2293 women (87%) reported on lymphedema in 2008 and 2012. Overall 37% reported lymphedema in 2008 while 31% reported lymphedema in 2012 and severity of symptoms decreased. 50% of women treated with SLNB and reporting lymphedema in 2008 did not report symptoms by 2012 in contrast to 30% treated with ALND. However, 19% of women treated with ALND and not reporting lymphedema in 2008 had developed lymphedema by 2012. In conclusion lymphedema remains a frequent problem, years after treatment for breast cancer, though, number of women reporting lymphedema and overall severity of symptoms decreased.

To test the hypothesis that the same genetic loci confer susceptibility to, or protection from, disease in different populations, and that a combined analysis would improve the map resolution of a common susceptibility locus, we analyzed data from three studies that had reported linkage to bipolar disorder in a small region on chromosome 4p. Data sets comprised phenotypic information and genetic marker data on Scottish, Danish, and USA extended pedigrees. Across the three data sets, 913 individuals appeared in the pedigrees, 462 were classified, either as unaffected (323) or affected (139) with unipolar or bipolar disorder. A consensus linkage map was created from 14 microsatellite markers in a 33 cM region. Phenotypic and genetic data were analyzed using a variance component (VC) and allele sharing method. All previously reported elevated test statistics in the region were confirmed with one or both analysis methods, indicating the presence of one or more susceptibility genes to bipolar disorder in the three populations in the studied chromosome segment. When the results from both the VC and allele sharing method were considered, there was strong evidence for a susceptibility locus in the data from Scotland, some evidence in the data from Denmark and relatively less evidence in the data from the USA. The test statistics from the Scottish data set dominated the test statistics from the other studies, and no improved map resolution for a putative genetic locus underlying susceptibility in all three studies was obtained. Studies reporting linkage to the same region require careful scrutiny and preferably joint or meta analysis on the same basis in order to ensure that the results are truly comparable.

To evaluate the prognostic significance of histologic grade on survival of ovarian serous cancer in Denmark during nearly 30 years. Using the nationwide Danish Pathology Data Bank, we evaluated 4317 women with ovarian serous carcinoma in 1978-2006. All pathology reports were scrutinized and tumors classified as either low-grade serous carcinomas (LGSC) or high-grade serous carcinomas (HGSC). Tumors in which the original pathology reports were described as well-differentiated were classified as LGSC, and those that were described as moderately or poorly differentiated were classified as HGSC. We obtained histologic slides from the pathology departments for women with a diagnosis of well-differentiated serous carcinoma during 1997-2006, which were then reviewed by expert gynecologic pathologists. Data were analyzed using Kaplan-Meier methods and Cox proportional hazards regression analysis with follow-up through June 2009. Women with HGSC had a significantly increased risk of dying (HR=1.9; 95% CI: 1.6-2.3) compared with women with LGSC while adjusting for age and stage. Expert review of 171 women originally classified as well-differentiated in 1997-2006 were interpreted as LGSC in 30% of cases, whereas 12% were interpreted as HGSC and 50% as serous borderline ovarian tumors (SBT). Compared with women with confirmed LGSC, women with SBT at review had a significantly lower risk of dying (HR=0.5; 95% CI: 0.22-0.99), and women with HGSC at review had a non-significantly increased risk of dying (HR=1.6; 95% CI: 0.7-3.4). A binary grading system is a significant predictor of survival for ovarian serous carcinoma. Copyright © 2012 Elsevier Inc. All rights reserved.

The Tilburg Frailty Indicator (TFI) is a self-administered questionnaire with a bio-psycho-social integrated approach that measures the degree of frailty in elderly persons. The TFI was developed in the Netherlands and tested in a population of elderly Dutch men and women. The aim of this study was to translate and culturally adapt the TFI to a Danish context, and to test face validity of the Danish version by cognitive interviewing. An internationally recognized procedure was applied as a basis for the translation process. The primary tasks were forward translation, reconciliation, back translation, harmonization and pretest. Pretest and review of the preliminary version by cognitive interviewing, were performed at a local community center and in an acute medical ward at the University Hospital in Aalborg, Denmark respectively. A large agreement regarding meaning of the items in the forward translation and reconciliation process was seen. Minor discrepancies were solved by consensus. Back translation revealed unclear wording in one matter. The harmonization committee agreed on a version for cognitive interviewing after revision of minor issues and thirty-four participants were interviewed. Two issues became evident and these were revised. The cognitive interviews and final lay-out resulted in minor adjustments as text type size, specific font, and lining for optimizing readability. In conclusion, we consider the TFI to be translated in such rigorous manner that the instrument can be further tested in clinical practice. The overall objective of the questionnaire being to identify frailty and improve the interventions relating to frail elderly persons in Denmark. Copyright © 2014 Elsevier Ireland Ltd.

We estimate demand curves for a one month reduction in waiting time for cataract surgery based on survey data collected in 1992 in Manitoba, Barcelona, and Denmark. Patients answered, "Would you be willing to pay [Bid, B] to reduce your waiting time for cataract surgery to less than one month?" Controlling for SES and visual status, Barcelonan patients have greater WTP for shortened waiting time than the Danes and Manitobans. We estimate the value (in 1992 $) of lost consumer surplus due to the cataract surgery queue at $128 per patient in Manitoba, $160 in Denmark, and $243 in Barcelona.
