    Aims: The purpose of this study was to analyze the prevalence of depression, anxiety, adjustment disorders, and somatoform disorders in patients diagnosed with age-related macular degeneration (AMD) in Germany. Methods: This study included 7,580 patients between the ages of 40 and 90 diagnosed with AMD between January 2011 and December 2014 in 1,072 primary care practices (index date). The last follow-up was in July 2016. We also included 7,580 controls without AMD, which were matched (1:1) to the AMD cases by age, sex, type of health insurance (private or statutory), physician, and Charlson comorbidity score as a generic marker of comorbidity. The outcome of the study was the prevalence of depression, anxiety, adjustment disorders, and somatoform disorders recorded in the database between the index date and the end of follow-up. Results: The mean age among subjects was 75.7 years (SD=10.1 years), 34.0% were men, and 7.8% had private health insurance coverage. The Charlson comorbidity index was 2.0 (SD=1.8). Depression was the most frequent disease (33.7% in AMD patients versus 27.3% in controls), followed by somatoform disorders (19.6% and 16.7%), adjustment disorders (14.8% and 10.5%), and anxiety disorders (11.7% and 8.2%). Depression (OR=1.37, 95% CI: 1.27–1.47), anxiety (OR=1.50, 95% CI: 1.35–1.67), adjustment disorders (OR=1.50, 95% CI: 1.36–1.65), and somatoform disorders (OR=1.22, 95% CI: 1.12–1.32) were all positively associated with AMD. Conclusion: Overall, a significant association was found between AMD and depression, anxiety, adjustment disorders, and somatoform disorders. PMID:28243189

    Community water fluoridation is considered a significant public health achievement of the 20th century. In this paper, the hypothesis that added water fluoridation has contributed to diabetes incidence and prevalence in the United States was investigated. Panel data from publicly available sources were used with population-averaged models to test the associations of added and natural fluoride on the outcomes at the county level in 22 states for the years 2005 and 2010. The findings suggest that a 1 mg increase in the county mean added fluoride significantly positively predicts a 0.23 per 1,000 person increase in age-adjusted diabetes incidence (P < 0.001), and a 0.17% increase in age-adjusted diabetes prevalence percent (P < 0.001), while natural fluoride concentration is significantly protective. For counties using fluorosilicic acid as the chemical additive, both outcomes were lower: by 0.45 per 1,000 persons (P < 0.001) and 0.33% (P < 0.001), respectively. These findings are adjusted for county-level and time-varying changes in per capita tap water consumption, poverty, year, population density, age-adjusted obesity and physical inactivity, and mean number of years since water fluoridation started. Sensitivity analyses revealed robust effects for both types of fluoride. Community water fluoridation is associated with epidemiological outcomes for diabetes.

    Because age is a significant variable in the occurrence and frequency of human disease, any comparison of disease or mortality rates, to be useful, must be age-specific or age-adjusted. Age-specific comparisons are not always appropriate or possible, however. A common method of eliminating the influence of age in comparing mortality rates from one community to another is to employ statistical methods of age-adjustment. While a variety of methods will accomplish this task, most are weighted averages of the age-specific rates. Two widely used adjustment procedures are direct and indirect age-adjustment.

    We examined the prevalence of type 2 diabetes and social deprivation in one urban district in Liverpool from October 1995 to September 1996 inclusive. This area has a stable Caucasian population of 176, 682. Lists were made of all known diabetics attending six different medical points of contact during the year, and were condensed and aggregated to eliminate duplicates. From postcode data, each patient was assigned to residence in one of the 14 electoral wards in the district, for which demographic structure and standardized measures of social deprivation were known (Townsend index). The crude period prevalences of type 1 and type 2 diabetes were estimated for each ward. Crude prevalence data were then corrected by applying capture-recapture (CR) techniques to the different patient datasets to allow for undercount. The crude period prevalence (95%CI) of diabetes was 1.5% (1.4-1.5%), or 2585/176, 682. The mean age of people with diabetes was not significantly different between electoral wards. The crude period prevalence of type 2 diabetes within individual wards ranged from 0.4% (0.3-0.6%) in the least deprived area to 4.1% (3.6-4.6%) in the most deprived area. The corresponding range of CR-adjusted period prevalence rates of type 2 diabetes was from 3.2% (2.8-3.6%) to 6.7% (6.1-7.4%), and there was strong correlation between both crude and CR-adjusted prevalence and social deprivation in each ward (r=0.76, p<0.001 for crude; and r=0. 49, p<0.005 for CR-adjusted prevalence). There was no correlation between the crude or CR-adjusted period prevalence rates of type 1 diabetes and Townsend index (r=0.14, p=NS). This strong correlation between the prevalence of type 2 diabetes and social deprivation has important implications for the planning of health-care delivery.

    Background The epidemiology of adjustment disorder in pregnant women is largely unknown. We sought to determine the prevalence and correlates of adjustment disorder in pregnant women in Durango City, Mexico. Methods Pregnant women (n = 300) attending in a public hospital in Durango City, Mexico were studied. All enrolled pregnant women had a psychiatric interview to evaluate the presence of adjustment disorder using the DSM-IV criteria. A questionnaire was submitted to obtain general epidemiological data of the pregnant women studied. Bivariate and multivariate analyses were used to assess the association of adjustment disorder with the epidemiological data of the women studied. Results Fifteen (5.0%) of the 300 women studied had adjustment disorder according to the DSM-IV criteria. Adjustment disorder was not associated with age, occupation, marital status, or education of pregnant women. In contrast, multivariate analysis of socio-demographic, clinical and psychosocial variables showed that adjustment disorder was associated with the variables lack of support from her couple (odds ratio (OR) = 3.83; 95% confidence interval (CI): 1.00 - 14.63; P = 0.04) and couple living abroad (OR = 10.12; 95% CI: 1.56 - 65.50; P = 0.01). Conclusions This is the first report about the epidemiology of adjustment disorder in pregnant women in Mexico. Results provide evidence of the presence of adjustment disorder and contributing psychosocial factors associated with this disorder in pregnant women in Mexico. Results point towards further clinical and research attention should be given to this neglected disorder in pregnant women. PMID:26346070

    A recent study using Heckman-type selection models to adjust for non-response in the Zambia 2007 Demographic and Health Survey (DHS) found a large correction in HIV prevalence for males. We aim to validate this finding, replicate the adjustment approach in other DHSs, apply the adjustment approach in an external empirical context, and assess the robustness of the technique to different adjustment approaches. We used 6 DHSs, and an HIV prevalence study from rural South Africa to validate and replicate the adjustment approach. We also developed an alternative, systematic model of selection processes and applied it to all surveys. We decomposed corrections from both approaches into rate change and age-structure change components. We are able to reproduce the adjustment approach for the 2007 Zambia DHS and derive results comparable with the original findings. We are able to replicate applying the approach in several other DHSs. The approach also yields reasonable adjustments for a survey in rural South Africa. The technique is relatively robust to how the adjustment approach is specified. The Heckman selection model is a useful tool for assessing the possibility and extent of selection bias in HIV prevalence estimates from sample surveys.

  17. Anger toward God: social-cognitive predictors, prevalence, and links with adjustment to bereavement and cancer.

    Many people see themselves as being in a relationship with God and see this bond as comforting. Yet, perceived relationships with God also carry the potential for experiencing anger toward God, as shown here in studies with the U.S. population (Study 1), undergraduates (Studies 2 and 3), bereaved individuals (Study 4), and cancer survivors (Study 5). These studies addressed 3 fundamental issues regarding anger toward God: perceptions and attributions that predict anger toward God, its prevalence, and its associations with adjustment. Social-cognitive predictors of anger toward God paralleled predictors of interpersonal anger and included holding God responsible for severe harm, attributions of cruelty, difficulty finding meaning, and seeing oneself as a victim. Anger toward God was frequently reported in response to negative events, although positive feelings predominated. Anger and positive feelings toward God showed moderate negative associations. Religiosity and age correlated negatively with anger toward God. Reports of anger toward God were slightly lower among Protestants and African Americans in comparison with other groups (Study 1). Some atheists and agnostics reported anger involving God, particularly on measures emphasizing past experiences (Study 2) and images of a hypothetical God (Study 3). Anger toward God was associated with poorer adjustment to bereavement (Study 4) and cancer (Study 5), particularly when anger remained unresolved over a 1-year period (Study 5). Taken together, these studies suggest that anger toward God is an important dimension of religious and spiritual experience, one that is measurable, widespread, and related to adjustment across various contexts and populations.

  18. Healthy aging and age-adjusted nutrition and physical fitness.

    Hammar, Mats; Ostgren, Carl Johan

    2013-10-01

    Expected life span is gradually increasing worldwide. Healthy dietary and exercise habits contribute to healthy ageing. Certain types of diet can prevent or reduce obesity, and may reduce the risk of diseases (e.g., cardiovascular disease). Exercise also reduces the risk of diseases (e.g., cardiovascular disease, osteoporosis, some cancers and some mental disturbances). A less sedentary life style seems at least as important as regular exercise. Exercise can probably be tailored to reduce the risk of cardiovascular disease and extent of bone loss. To ensure adherence, it is important to increase slowly the frequency, duration and intensity of exercise, and to find activities that suit the individual. More research is needed to find ideal modes and doses of exercise, and to increase long-term adherence. Dietary and exercise modification seem to be strong promoters of healthy ageing.

    There is increasing evidence, mainly from daily time series studies, linking air pollution and stroke. Small area level geographical correlation studies offer another means of examining the air pollution-stroke association. Populations within small areas may be more homogeneous than those within larger areal units, and census-based socioeconomic information may be available to adjust for confounding effects. Data on smoking from health surveys may be incorporated in spatial analyses to adjust for potential confounding effects but may be sparse at the small area level. Smoothing, using data from neighbouring areas, may be used to increase the precision of smoking prevalence estimates for small areas. We examined the effect of modelled outdoor NOx levels on stroke mortality using a Bayesian hierarchical spatial model to incorporate random effects, in order to allow for unmeasured confounders and to acknowledge sampling error in the estimation of smoking prevalence. We observed an association between NOx and stroke mortality after taking into account random effects at the small area level. We found no association between smoking prevalence and stroke mortality at the small area level after modelling took into account imprecision in estimating smoking prevalence. The approach we used to incorporate smoking as a covariate in a single large model is conceptually sound, though it made little difference to the substantive results.

  20. Prevalence of cognitive impairment in individuals aged over 65 in an urban area: DERIVA study

    2011-01-01

    Background Few data are available on the prevalence of cognitive impairment (CI) in Spain, and the existing information shows important variations depending on the geographical setting and the methodology employed. The aim of this study was to determine the prevalence of CI in individuals aged over 65 in an urban area, and to analyze its associated risk factors. Methods Design: A descriptive, cross-sectional, home questionnaire-based study; Setting: Populational, urban setting. Participants: The reference population comprised over-65s living in the city of Salamanca (Spain) in 2009. Randomized sampling stratified according to health district was carried out, and a total of 480 people were selected. In all, 327 patients were interviewed (68.10%), with a mean age of 76.35 years (SD: 7.33). Women accounted for 64.5% of the total. Measurements: A home health questionnaire was used to obtain the following data: age, sex, educational level, family structure, morbidity and functionality. All participants completed a neuropsychological test battery. The prevalence data were compared with those of the European population, with direct adjustment for age and sex. Diagnoses were divided into three general categories: normal cognitive function, cognitive impairment - no dementia (CIND), and dementia. Results The prevalence of CI among these over-65s was 19% (14.7% CIND and 4.3% dementia). The age-and sex-adjusted global prevalence of CI was 14.9%. CI increased with age (p < 0.001) and decreased with increasing educational level (p < 0.001). Significant risk factors were found with the multivariate analyses: age (OR = 1.08, 95%CI: 1.03-1.12), anxiety-depression (OR = 3.47, 95%CI: 1.61-7.51) and diabetes (OR = 2.07, 95%CI: 1.02-4.18). In turn, years of education was found to be a protective factor (OR = 0.79, 95%CI: 0.70-0.90). Although CI was more frequent among women and in people living without a partner, these characteristics were not significantly associated with CI risk

    Background: Intellectual disability (ID) is a global public health concern. Prevalence of ID and its association with age and other demographic factors is required for planning purposes in India. Objective: This study analyzed the age-adjusted prevalence of ID in rural and urban populations and its correlation with age in children and adults. Materials and Methods: Disability data published in the report (2002) of National Sample Survey Organization were analyzed, using Z-test to measure differences in age-adjusted prevalence. Spearman rho was calculated to determine strength and direction of the association, and regression analysis was used to predict prevalence rate, based on age in rural and urban population settings. Results: Overall, India has a prevalence of 10.5/1000 in ID. Urban population has slightly higher rate (11/1000) than rural (10.08/1000; P = 0.044). Age was found to be highly correlated with prevalence of ID in rural children (ϱ =0.981, P = 0.019) as well as in children (ϱ = −0.954, P = 0.000) and adults (ϱ = −0.957, P = 0.000) in urban population. The possibility of confounding or the existence of covariates for children in urban settings was noted. Conclusion: Results of this study match findings in other epidemiological studies. However, multistage, large-scale studies are recommended for investigating prevalence rates with different severity levels of ID. PMID:26752897

  6. Incidence, prevalence, and hybrid approaches to calculating disability-adjusted life years

    PubMed Central

    2012-01-01

    When disability-adjusted life years are used to measure the burden of disease on a population in a time interval, they can be calculated in several different ways: from an incidence, pure prevalence, or hybrid perspective. I show that these calculation methods are not equivalent and discuss some of the formal difficulties each method faces. I show that if we don’t discount the value of future health, there is a sense in which the choice of calculation method is a mere question of accounting. Such questions can be important, but they don’t raise deep theoretical concerns. If we do discount, however, choice of calculation method can change the relative burden attributed to different conditions over time. I conclude by recommending that studies involving disability-adjusted life years be explicit in noting what calculation method is being employed and in explaining why that calculation method has been chosen.

    Objective: To investigate how associations between education and brain structure in older age were affected by adjusting for IQ measured at age 11. Methods: We analyzed years of full-time education and measures from an MRI brain scan at age 73 in 617 community-dwelling adults born in 1936. In addition to average and vertex-wise cortical thickness, we measured total brain atrophy and white matter tract fractional anisotropy. Associations between brain structure and education were tested, covarying for sex and vascular health; a second model also covaried for age 11 IQ. Results: The significant relationship between education and average cortical thickness (β = 0.124, p = 0.004) was reduced by 23% when age 11 IQ was included (β = 0.096, p = 0.041). Initial associations between longer education and greater vertex-wise cortical thickness were significant in bilateral temporal, medial-frontal, parietal, sensory, and motor cortices. Accounting for childhood intelligence reduced the number of significant vertices by >90%; only bilateral anterior temporal associations remained. Neither education nor age 11 IQ was significantly associated with total brain atrophy or tract-averaged fractional anisotropy. Conclusions: The association between years of education and brain structure ≈60 years later was restricted to cortical thickness in this sample; however, the previously reported associations between longer education and a thicker cortex are likely to be overestimates in terms of both magnitude and distribution. This finding has implications for understanding, and possibly ameliorating, life-course brain health. PMID:27664981

    Background Identification of patients at risk of death from cancer surgery should aid in preoperative preparation. The purpose of this study is to assess and adjust the age-adjusted Charlson comorbidity index (ACCI) to identify cancer patients with increased risk of perioperative mortality. Methods We identified 156,151 patients undergoing surgery for one of the ten common cancers between 2007 and 2011 in the Taiwan National Health Insurance Research Database. Half of the patients were randomly selected, and a multivariate logistic regression analysis was used to develop an adjusted-ACCI score for estimating the risk of 90-day mortality by variables from the original ACCI. The score was validated. The association between the score and perioperative mortality was analyzed. Results The adjusted-ACCI score yield a better discrimination on mortality after cancer surgery than the original ACCI score, with c-statics of 0.75 versus 0.71. Over 80 years of age, 70–80 years, and renal disease had the strongest impact on mortality, hazard ratios 8.40, 3.63, and 3.09 (P < 0.001), respectively. The overall 90-day mortality rates in the entire cohort varied from 0.9%, 2.9%, 7.0%, and 13.2% in four risk groups stratifying by the adjusted-ACCI score; the adjusted hazard ratio for score 4–7, 8–11, and ≥ 12 was 2.84, 6.07, and 11.17 (P < 0.001), respectively, in 90-day mortality compared to score 0–3. Conclusions The adjusted-ACCI score helps to identify patients with a higher risk of 90-day mortality after cancer surgery. It might be particularly helpful for preoperative evaluation of patients over 80 years of age. PMID:26848761

The aim of this paper is to estimate the prevalence of successful aging in the elderly in Western Mexico and to analyze its variability by age, sex, education, marital status, and pension. Methods. This study employs data from the Health, Wellbeing, and Aging Study (SABE) in Jalisco and Colima, Mexico. Successful aging was operationalized in accordance with no important disease, no disability, physical functioning, cognitive functioning, and being actively. There were a total of 3116 elderly. Results. 12.6% of older adults were "successful" aging. The old-old is a lower proportion of successful aging people; it ranges from 18.9% among people aged 60-69 years to 3.9% in the 80-89 years and up to 1% in people 90 and older. There were also differences according to sex (P = .000), with a higher proportion of successful aging men (18.4% compared with 9.2% of women). There were differences in educational level (P = .000); those higher with education were found to be more successful aging, and also there were differences in marital status for married people (P = .000). Discussion. A small number of older adults meet the criteria definition of successful aging, suggesting the need to analyze in depth the concept and the indicators.

    To investigate sociodemographic factors associated with adolescent females ages 14-16 years having children fathered by males age 20 years or older and identify differences in correlates across rural, urban, and border areas. The method section was a cross-sectional study using Texas birth record data. From 2000 through 2004, there were 29,186 births to adolescent females aged 14-16 years with valid paternal age. Prevalence of and adjusted odds of paternal age of 20 years or older were identified by paternal and maternal factors. The Results section Having both parents born outside of the U.S. was associated with a 5.29 (95% CI: 4.82, 5.80) times increase in the odds of paternal age of 20 years or older as compared to having both parents born in the U.S. Parental place of birth was associated with greater odds of paternal age of 20 years or older in urban areas compared to rural or border areas. Compared to those with average or high educational attainment relative to age, low educational attainment relative to age was associated with an increase in the odds of paternal age of 20 years or older. This association was present whether maternal or paternal educational attainment was low relative to age. Messages are needed to help adolescent females avoid pregnancy with adult males. In addressing this specific prevention challenge, it is important to consider maternal/paternal place of birth and its association with adolescent births with adult males.

    We examined the effects of age on automatic and voluntary motor adjustments in pointing tasks. To this end, young (20-25 years) and middle-aged adults (48-62 years) were instructed to point at a target that could unexpectedly change its location (to the left or right) or its color (to green or red) during the movement. In the location change conditions, participants were asked to either adjust their pointing movement toward the new location (i.e., normal pointing) or in the opposite direction (i.e., anti-pointing). In the color change conditions, participants were instructed to adjust their movement to the left or right depending on the change in color. The results showed that in a large proportion of the anti-pointing trials, participants made two adjustments: an early initial automatic adjustment in the direction of the target shift followed by a late voluntary adjustment toward the opposite direction. It was found that the late voluntary adjustments were delayed for the middle-aged participants relative to the young participants. There were no age differences for the fast automatic adjustment in normal pointing, but the early adjustment in anti-pointing tended to be later in the middle-aged adults. Finally, the difference in the onset of early and late adjustments in anti-pointing adjustments was greater among the middle-aged adults. Hence, this study is the first to show that aging slows down voluntary goal-directed movement control processes to greater extent than the automatic stimulus-driven processes.

    Evidence from epidemiological studies reported that height was inversely associated with cardiovascular diseases, but the association between height and hypertension was unclear. The purpose of this study was to explore the association between height and blood pressure or prevalence of hypertension in a middle-aged and older Chinese population. A total of 33,197 participants aged 37 to 94 years were recruited from the Dongfeng-Tongji cohort study in Hubei province, China. All participants completed baseline questionnaires, medical examinations and provided blood samples. Hypertension was define as a systolic blood pressure (SBP) over 140 mmHg or/and a diastolic blood pressure (DBP) over 90 mmHg, or current use of antihypertensive medication, or participants with self-reported physician diagnosis of hypertension. Multivariate linear and logistic regression models were used. The prevalence of hypertension was 69.1% for men and 58.0% for women. Pulse pressure (PP) and SBP, but not DBP decreased linearly with increasing height among men and women. Comparing the highest with the shortest quartile of height, the multivariate-adjusted odds ratios were 0.80 (95% confidence interval, 0.71, 0.91) for men and 0.83 (0.74, 0.92) for women. In conclusion, height was associated with reduced SBP, PP and prevalence of hypertension in a middle-aged and older Chinese population. PMID:28000763

    The Roma (Gypsy) are the largest European minority population characterized by poverty, social exclusion as well as by numerous life-style and cultural specificities, which all could have an adverse impact on their cardiovascular health. This study assesses the prevalence of cardiovascular diseases (CVD) risk factors in community-based sample of 430 adult Roma, living in rural area of Croatia, by providing the actual and age-adjusted estimates using the European standard population. The most prominent classical CVD risk phenotypes (blood pressure, obesity, smoking, glucose and lipid profile) were selected, and the standard risk cut-offs were applied. The study has shown that compared to general population of Croatia, the Roma population bears a high CVD risk factors load related to smoking and high glucose level. The CVD risk factors prevalence in Roma also showed important sex and age patterns, the most imposing of which are the findings of higher prevalence of CVD risks in women (especially obesity and triglyceride levels) and the trend of higher body mass index (BMI) level in younger age group (18-34 years) which both stand in contrast to the trends characterizing the general population of Croatia. These findings are complemented by the trend of decreased risk in the oldest age group (65+ years) for all investigated CVD risk factors (with exception of triglycerides level) compared to the 50-64 age group. We conclude that the age and sex CVD risks pattern point to the health transition of this rural Roma population. As we expect the proportion of CVD in the Roma minority of Croatia to increase in the future along with further modernization of their lifestyle, the CVD prevention measures in this population are urgent and should be primarily targeted at women and at the younger segment of this population.

    Introduction HIV testing is a cornerstone of efforts to combat the HIV epidemic, and testing conducted as part of surveillance provides invaluable data on the spread of infection and the effectiveness of campaigns to reduce the transmission of HIV. However, participation in HIV testing can be low, and if respondents systematically select not to be tested because they know or suspect they are HIV positive (and fear disclosure), standard approaches to deal with missing data will fail to remove selection bias. We implemented Heckman-type selection models, which can be used to adjust for missing data that are not missing at random, and established the extent of selection bias in a population-based HIV survey in an HIV hyperendemic community in rural South Africa. Methods We used data from a population-based HIV survey carried out in 2009 in rural KwaZulu-Natal, South Africa. In this survey, 5565 women (35%) and 2567 men (27%) provided blood for an HIV test. We accounted for missing data using interviewer identity as a selection variable which predicted consent to HIV testing but was unlikely to be independently associated with HIV status. Our approach involved using this selection variable to examine the HIV status of residents who would ordinarily refuse to test, except that they were allocated a persuasive interviewer. Our copula model allows for flexibility when modelling the dependence structure between HIV survey participation and HIV status. Results For women, our selection model generated an HIV prevalence estimate of 33% (95% CI 27–40) for all people eligible to consent to HIV testing in the survey. This estimate is higher than the estimate of 24% generated when only information from respondents who participated in testing is used in the analysis, and the estimate of 27% when imputation analysis is used to predict missing data on HIV status. For men, we found an HIV prevalence of 25% (95% CI 15–35) using the selection model, compared to 16% among those who

    Cardiovascular diseases (CVD) and especially coronary heart disease (CHD) are the main causes of death in the Slovak Republic (SR). The aim of this study is to explore trends in age-adjusted coronary heart disease mortality rates in the whole Slovak population and in the population of working age between the years 1993 and 2009. A related indicator - potential years of life lost (PYLL) due to CHD--was calculated in the same period for males and females. Crude CHD mortality rates were age-adjusted using European standard population. The joinpoint Poisson regression was performed in order to find out the annual percentage change in trends. The age-adjusted CHD mortality rates decreased in the Slovak population and also in the population of working age. The change was significant only within the working-age sub-group. We found that partial diagnoses (myocardial infarction and chronic ischaemic heart disease) developed in the mirror-like manner. PYLL per 100,000 decreased during the observed period and the decline was more prominent in males. For further research we recommend to focus on several other issues, namely, to examine the validity of cause of death codes, to examine the development of mortality rates in selected age groups, to find out the cause of differential development of mortality rates in the Slovak Republic in comparison with the Czech Republic and Poland, and to explain the causes of decrease of the age-adjusted CHD mortality rates in younger age groups in Slovakia.

    Background The ongoing need for an availability of informal carers is taking on greater relevance as the global burden of disease transitions from acute fatal diseases to long term morbidity. Growing evidence suggests that extra burden on family carers may further impact on their health and ability to provide care. Important as it is to monitor the prevalence of those conditions which influence the burden of disease, it is also important to monitor the prevalence and health profiles of those who provide the informal care. The aim of this study was to demonstrate the prevalence and demographics of adult carers aged 15 and over in the state of South Australia over 20 years between 1994 and 2014. Methods Data from nine representative, cross-sectional population surveys, conducted in South Australia, Australia were used, (total N = 26,788 and n = 1,504 carers). The adjusted prevalence estimate of carers and their demographic characteristics were determined. So as to examine whether there were any generational effects on the prevalence of carers, an Age-Period Cohort (APC) analysis was undertaken. Results The prevalence estimates of carers increased during the two decades from 3.7% in 1994 to 6.7% by 2014. Large increases in the proportion of retired carers, those aged 70 years and over, those carers employed, and those with higher educational qualifications were observed. There were also larger proportions of respondents with a country of birth other than Australia, UK, Ireland and European counties. The APC analysis illustrated an increasing prevalence rate over each decade for carers aged 20–80 years, especially for those over the age of 60 years. Conclusions The results illustrate changing carer characteristics and carer prevalence estimates in South Australia as new generations of carers take on the caring role. There is a need to include questions regarding informal carers within ongoing mainstream population surveys, particularly at state levels, so as to plan

    The goal of this study was to provide an in-depth examination of friendships within organized activities. The prevalence of friendships with co-participants, their quality and characteristics, and their associations with adjustment were investigated. A sample of 281 (60% girls) 8th grade adolescents reported their friendships, activities, and adjustment. The results showed that 70% of youths have friends who co-participate with them. Friends in individual sports are more academically oriented whereas friends in team sports are more supportive but display higher levels of problem behavior. Finally, having friends in activities is associated with lower problem behavior and better academic functioning.

    Care practices and risk factors for diarrhea among impoverished communities across Mesoamerica are unknown. Using Salud Mesoamérica Initiative baseline data, collected 2011–2013, we assessed the prevalence of diarrhea, adherence to evidence-based treatment guidelines, and potential diarrhea correlates in poor and indigenous communities across Mesoamerica. This study surveyed 14,500 children under 5 years of age in poor areas of El Salvador, Guatemala, Mexico (Chiapas State), Nicaragua, and Panama. We compared diarrhea prevalence and treatment modalities using χ2 tests and used multivariable Poisson regression models to calculate adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) for potential correlates of diarrhea. The 2-week point prevalence of diarrhea was 13% overall, with significant differences between countries (P < 0.05). Approximately one-third of diarrheal children were given oral rehydration solution and less than 3% were given zinc. Approximately 18% were given much less to drink than usual or nothing to drink at all. Antimotility medication was given to 17% of diarrheal children, while antibiotics were inappropriately given to 36%. In a multivariable regression model, compared with children 0–5 months, those 6–23 months had a 49% increased risk for diarrhea (aRR = 1.49, 95% CI = 1.15, 1.95). Our results call for programs to examine and remedy low adherence to evidence-based treatment guidelines. PMID:26787152

    School-aged children (6-15 years) from the endemic area of Pernambuco were evaluated both as a target group for and an indicator of schistosomiasis control in the community. Parasitological data were drawn from baseline stool surveys of whole populations that were obtained to diagnose Schistosoma mansoni infection. Nineteen representative localities were selected for assessing the prevalence of schistosomiasis among individuals in the following age groups: 0-5, 6-15, 16-25, 26-40 and 41-80 years. For each locality, the prevalence in each age group was compared to that of the overall population using contingency table analysis. To select a reference group, the operational difficulties of conducting residential surveys were considered. School-aged children may be considered to be the group of choice as the reference group for the overall population for the following reasons: (i) the prevalence of schistosomiasis in this age group had the highest correlation with the prevalence in the overall population (r = 0.967), (ii) this age group is particularly vulnerable to infection and plays an important role in parasite transmission and (iii) school-aged children are the main target of the World Health Organization in terms of helminth control. The Schistosomiasis Control Program should consider school-aged children both as a reference group for assessing the need for intervention at the community level and as a target group for integrated health care actions of the Unified Health System that are focused on high-risk groups.

    This paper is a contribution to lithium-ion batteries modelling taking into account aging effects. It first analyses the impact of aging on electrode stoichiometry and then on lithium-ion cell Open Circuit Voltage (OCV) curve. Through some hypotheses and an appropriate definition of the cell state of charge, it shows that each electrode equilibrium potential, but also the whole cell equilibrium potential can be modelled by a polynomial that requires only one adjustment parameter during aging. An adjustment algorithm, based on the idea that for two fixed OCVs, the state of charge between these two equilibrium states is unique for a given aging level, is then proposed. Its efficiency is evaluated on a battery pack constituted of four cells.

    The objective of this study was to explore the association between health and urbanization in a megacity, Shanghai, by calculating the age-adjusted mortality ratio by ward-unit of Shanghai and by examining relationships between mortalities and urban indicators. Crude mortality rates and age-adjusted mortality ratios by ward-unit were calculated. Demographic, residential environment, healthcare, and socioeconomic indicators were formulated for each of the ward-units between 1995 and 1998. Correlation and Poisson regression analyses were performed to examine the association between urban indicators and mortalities. The crude mortality rate by ward-unit in 1997 varied from 6.3 to 9.4 deaths per 1000 population. The age-adjusted mortality ratio in 1997 by ward-units as reference to the average mortality of urban China varied from 57.8 to 113.3 within Shanghai. Age-adjusted mortalities were inversely related with indicators of a larger floor space of dwellings per population, a larger proportion of parks, gardens, and green areas to total land area; a greater number of health professionals per population; and a greater number of employees in retail business per population. Spacious living showed independent association to a higher standard of community health in Shanghai (P < 0.05). Consequences of health policy and the developments of urban infrastructural resources from the viewpoint of the Healthy Cities concept were discussed.

    Bidirectional associations between child temperament (fear, frustration, positive affect, effortful control) and parenting behaviors (warmth, negativity, limit setting, scaffolding, responsiveness) were examined as predictors of preschool-age children's adjustment problems and social competence. Participants were a community sample of children (N = 306; 50% female, 64% European American) and their mothers. Observational measures of child temperament and parenting were obtained using laboratory tasks at two time points (children's ages 36 and 54 months). Teacher-reported adjustment measures were collected at the first and third time points (children's ages 36 and 63 months). Cross-lagged analyses were performed to examine whether child temperament and parenting predict changes in one another, whether they each contribute independently to children's adjustment, and whether these transactional relations account for adjustment outcomes. Maternal negativity at 36 months predicted increases in child frustration at 54 months. Maternal negativity and child effortful control predicted decreases in each other from 36 to 54 months. Maternal warmth predicted increases in child effortful control over time. Child frustration, child effortful control, maternal warmth, and maternal negativity at 54 months each independently predicted child adjustment problems at 63 months, controlling for problems at 36 months. Child executive control at 54 months predicted increases in child social competence at 63 months. The findings suggest that temperament and parenting have independent and additive effects on preschool-age child adjustment, with some support for a bidirectional relation.

    Background Few studies to date have described the prevalence of electrocardiographic (ECG) abnormalities in a biracial middle-aged cohort. Methods and Results Participants underwent measurement of traditional risk factors and 12-lead ECGs coded using both Minnesota Code (MC) and Novacode (NC) criteria. Among 2585 participants, of whom 57% were women and 44% were black (mean age 45 years), the prevalence of major and minor abnormalities were significantly higher (all P<0.001) among black men and women compared to whites. These differences were primarily due to higher QRS voltage and ST/T wave abnormalities among blacks. There was also a higher prevalence of Q waves (MC 1-1, 1-2, 1-3) than described by previous studies. These racial differences remained after multivariate adjustment for traditional cardiovascular (CV) risk factors. Conclusions Black men and women have a significantly higher prevalence of ECG abnormalities, independent of traditional CV risk factors, than whites in a contemporary cohort middle-aged participants.

    Objective: In Brazil, demographic, socioeconomic and epidemiological changes over time have led to a transition in nutritional standards, resulting in a gradual reduction of malnutrition and an increased prevalence of overweight and obese individuals, similar to the situation in developed countries in previous decades. This study assessed the body mass index (BMI) and the prevalence of an overweight status and obesity, adjusted for various factors, in a population in northeastern Brazil including all age groups. Methods: This is a cross-sectional population-based epidemiological study using single sampling procedure composed of levels. Given the heterogeneity of the variable “income” and the relationship between income, prevalence of diseases and nutrition, a stratified sampling on blocks in the first level was used. In this, city districts were classified by income into 10 strata, according to information obtained from IBGE. A systematic sampling was applied on randomly selected blocks in order to choose the residences that would be part of the sample (second level), including 1165 participants from all age groups. Results and Discussion: The prevalence of an overweight status or obesity was adjusted for demographic, socioeconomic and lifestyle variables. When the Chi-square test was applied, a relationship was observed between the prevalence of an overweight status or obesity and the age group, gender, educational level and income of the participants. Regarding lifestyle parameters, only smoking was associated with the prevalence of an overweight status or obesity, in both adults and in the total sample. The results for the following groups were significant (p < 0.05): the age group from 20 to 59 years, when the individual presented an educational level greater than or equal to high school; and the age group ≥ 60 years, when the individual was female. It is noteworthy that educational level and being female were significant in adjusting for the total

    Rationale: Asthma is a variable condition with an apparent tendency for a natural decline in asthma symptoms and health care use occurring as children age. As a result, asthma interventions using a pre-post design may overestimate the intervention effect when no proper control group is available. Objectives: Investigate patterns of natural decline over time with increasing age in asthma symptoms and health care use of children. Develop a statistical procedure that enables adjustment that accounts for expected declines in these outcomes and is useable when intervention evaluations must rely solely on pre-post data. Methods: Mixed-effects models with mixture distributions were used to describe the pattern of symptoms and health care use in 3,021 children aged 2 to 15 years in a combined sample from three controlled trials. An adaptive least squares estimation was used to account for overestimation of intervention effects and make adjustments for pre-post only data. Termed “Adjustment for Natural Declines in Asthma Outcomes (ANDAO),” the adjustment method uses bootstrap sampling to create control cohorts comparable to subjects in the intervention study from existing control subjects. ANDAO accounts for expected declines in outcomes and is beneficial when intervention evaluations must rely solely on pre-post data. Measurements and Main Results: Children under 10 years of age experienced 18% (95% confidence interval, 15–21%) fewer symptom days and 28% (95% confidence interval, 24–32%) fewer symptom nights with each additional year of age. The decline was less than 10% after age 10 years, depending on baseline asthma severity. Emergency department visits declined regardless of baseline symptom frequency (P = 0.02). The adjustment method corrected estimates to within 2.4% of true effects through simulations using control cohorts. Conclusions: Because of the declines in symptoms and health care use expected with increasing age of children with asthma, pre

    This study assessed the prevalence rates of physical, verbal, relational, property, and cyber bullying among a sample of South Korean middle school students. Associations between bullying and a list of psychopathological symptoms were also examined. Finally, whether a link between bullying and psychopathological symptoms is modified by the level of parental attachment was examined. Results show that, contrary to Western studies, girls were more likely than boys to be involved in school bullying. Significant interaction effects between parental attachment and bully/victim status on depression were also discovered.

    Carotid plaque (CP) is associated with cardiovascular and cerebrovascular events. However, population-based studies with a large sample are rare in China, particularly those in the low-income population. We aimed to determine the prevalence of CP and the associated risk factors in the rural areas of northern China. Between April 2014 and June 2014, we recruited 3789 residents aged ≥45 years. B-mode ultrasonography was performed to measure the extent of CP. The prevalence of CP was 40.3% overall, 47.1% in men, and 35.4% in women (P < 0.001). The prevalence of CP increased with increasing age (P < 0.001). The participants with CP were more likely to have hypertension, diabetes, high total cholesterol (TC) levels, and high low-density lipoprotein-cholesterol levels and be a current smoker; however, they were less likely to be obese. Multiple logistic regression analysis, adjusted for confounders, indicated that age, male sex, hypertension, diabetes, current smoking, and high LDL-C levels were the independent risk factors for CP. There was a lower risk of CP with alcohol consumption. The findings suggest that managing the conventional risk factors is crucial to reduce the burden of cardiovascular and cerebrovascular diseases in the low-income population in China.

  16. Prevalence of cataract in adult Down's syndrome patients aged 28 to 83 years

    2007-01-01

    Background Age-related cataract is the major cause of blindness in humans throughout the world. The majority of previous studies of cataract in Down's syndrome (which usually results from trisomy 21) have reported that the prevalence of this ocular abnormality is higher for a given age range than in the general population. The objective of the present study was to study the prevalence of cataract in a well-defined population of adults with Down's syndrome. Methods An in-patient population of 68 adults (35 males and 33 females) with Down's syndrome, aged between 28.9 and 83.3 years, underwent ophthalmological examination for the presence of cataracts. Results Overall, the prevalence of cataract was 16.2%, with no significant difference in the prevalence between males (17.1%) and females (15.2%). In those aged between 45 and 64 years, the prevalence was 16.7%, rising in those aged between 65 and 75 years to 28.6%. Conclusion Compared with the general population, the prevalence of cataract in Down's syndrome was raised in those aged 45 to 64, but not in those aged 65 to 75 years; the latter might be a function of the relatively small number of patients in this age group. The increased prevalence of cataract found in those in the 45- to 64-year-old age group may be the result of increased levels of the copper- and zinc-containing superoxide dismutase enzyme (CuZnSOD), in turn resulting from the location of the associated five exons of SOD1 on chromosome 21. These elevated levels of superoxide dismutase may give rise to increased levels of reactive species, including hydrogen peroxide and hydroxyl radicals, which may increase the risk of cataractogenesis. It is suggested that nutritional supplementation with antioxidants may therefore help reduce the prevalence of cataract in Down's syndrome. PMID:18034878

    OBJECTIVE Understanding how young girls respond to growing up with breast cancer family histories is critical given expansion of genetic testing and breast cancer messaging. We examined the impact of breast cancer family history on psychosocial adjustment and health behaviors among >800 girls in the multicenter LEGACY Girls Study. METHODS Girls aged 6 to 13 years with a family history of breast cancer or familial BRCA1/2 mutation (BCFH+), peers without a family history (BCFH−), and their biological mothers completed assessments of psychosocial adjustment (maternal report for 6- to 13-year-olds, self-report for 10- to 13-year-olds), breast cancer–specific distress, perceived risk of breast cancer, and health behaviors (10- to 13-year-olds). RESULTS BCFH+ girls had better general psychosocial adjustment than BCFH− peers by maternal report. Psychosocial adjustment and health behaviors did not differ significantly by self-report among 10- to 13-year-old girls. BCFH+ girls reported higher breast cancer–specific distress (P = .001) and were more likely to report themselves at increased breast cancer risk than BCFH− peers (38.4% vs 13.7%, P < .001), although many girls were unsure of their risk. In multivariable analyses, higher daughter anxiety was associated with higher maternal anxiety and poorer family communication. Higher daughter breast cancer–specific distress was associated with higher maternal breast cancer-specific distress. CONCLUSIONS Although growing up in a family at risk for breast cancer does not negatively affect general psychosocial adjustment among preadolescent girls, those from breast cancer risk families experience greater breast cancer–specific distress. Interventions to address daughter and mother breast cancer concerns and responses to genetic or familial risk might improve psychosocial outcomes of teen daughters. PMID:26482668

    1. There is considerable interest in patterns of age-dependent reproductive effort and reproductive timing of large iteroparous mammals living in strongly seasonal environments. Due to lack of data on both timing of mating and birth, there is generally little insight into whether variation in gestation length play a role for life-history patterns observed for large mammals at northern latitudes. 2. Based on data on both timing of mating and birth of 88 female reindeer (and paternity confirmed with DNA fingerprinting), we explore the view that adjustment of gestation length plays a role in the reproductive tactic. 3. Observed gestation lengths of reindeer varied between 211 and 229 days (mean of 221 days). Consistent with a dynamic view of gestation length, variation could be predicted from life-history traits. Gestation length was longer for male than female offspring, which is expected in polygynous species where males benefit more from extra allocation of maternal resources. Gestation length increased with maternal age both due to direct effects and indirect effects linked to earlier mating of older, heavier females. Early mating females increased gestation length. A relatively small effect of female age on birth mass operated through variation in gestation length. 4. Our analysis supports the view that adjustment of gestation length is a part of the reproductive tactic of large mammals in northern environments.

    Background: Coronary heart disease (CHD) was the second leading cause of death in Malaysia in 2006. CHD has known risk factors including hypertension, diabetes mellitus, and obesity. Methods: This cross-sectional study examined the prevalence of cardiovascular risk factors among 260 participants aged 20 to 65 years in a rural community in Sarawak. Results: The prevalences of overweight and obesity in this study were 39.6% and 11.9%, respectively. Approximately 13% of participants had hypertension, and 1.5% had a random blood sugar greater than 11.1 mmol/L. Chi-square tests showed significant associations between obesity and gender (P = 0.007), low high-density lipoprotein cholesterol and race (P = 0.05), high total cholesterol and age (P = 0.007), age and hypertension (P = 0.011), smoking and gender (P < 0.001), and smoking and income (P = 0.050). Age-adjusted logistic regression showed that women were 0.246 times more likely to be obese, that older participants (> 45 years) were 0.395 times more likely to have high cholesterol and that those with a higher monthly household income (> RM830) were 2.471 times more likely to smoke. Conclusion: These findings indicate that we should be concerned about the high rates of overweight in this rural community to prevent obesity. PMID:22973135

  20. Seasonal prevalence of Taenia taeniaeformis: relationship to age, sex, reproduction and abundance of an intermediate host (Peromyscus maniculatus).

    Livers from 4,501 deer mice (Peromyscus maniculatus) collected from a weedy habitat in northeastern California during 48 consecutive monthly samplings were examined microscopically for Taenia taeniaeformis larva. Although there were pronounced seasonal fluctuations in host density, there were no significant annual or season-related differences in cestode intensities in adult deer mice. There were no significant differences in prevalences associated with sex of the host, nor were there significant changes in level of reproduction noted between infected and non-infected hosts. There were, however, significant differences in prevalences between young (1.2%) and adult (4.2%) hosts. Plausible mechanisms for this age-related difference in prevalence rates include (1) differential susceptibility due to the activity pattern of adult mice and/or (2) passive immunity in neonates as a result of colostrum- and/or transplacentally-transferred immunoglobulins and (3) capture of subadult animals before they had completed the period of highest susceptibility to T. taeniaeformis. Density of larvae per mouse liver was determined during a 21 mo consecutive period. The intensity of T. taeniaeformis larvae was not significantly different between the sexes of the adult mice. The larval stage showed an overdispersion pattern within the adult population. These results suggest that determinations of T. taeniaeformis abundances can be accurately made, at least in this P. maniculatus population, at any time of the year provided adjustment is made for the relative age structure of the host population.

  1. A stochastic version of the brass PF ratio adjustment of age-specific fertility schedules.

    PubMed

    Baker, Jack; Alcantara, Adélamar; Ruan, Xiaomin

    2011-01-01

    Estimates of age-specific fertility rates based on survey data are known to suffer down-bias associated with incomplete reporting. Previously, William Brass (1964, 1965, 1968) proposed a series of adjustments of such data to reflect more appropriate levels of fertility through comparison with data on children-ever-born by age, a measure of cohort-specific cumulative fertility. His now widely-used Parity/Fertility or PF ratio method makes a number of strong assumptions, which have been the focus of an extended discussion in the literature on indirect estimation. However, while it is clear that the measures used in making adjusted age-specific fertility estimates with this method are captured with statistical uncertainty, little discussion of the nature of this uncertainty around PF-ratio based estimates of fertility has been entertained in the literature. Since both age-specific risk of childbearing and cumulative parity (children ever born) are measured with statistical uncertainty, an unknown credibility interval must surround every PF ratio-based estimate. Using the standard approach, this is unknown, limiting the ability to make statistical comparisons of fertility between groups or to understand stochasticity in population dynamics. This paper makes use of approaches applied to similar problems in engineering, the natural sciences, and decision analysis--often discussed under the title of uncertainty analysis or stochastic modeling--to characterize this uncertainty and to present a new method for making PF ratio-based fertility estimates with 95 percent uncertainty intervals. The implications for demographic analysis, between-group comparisons of fertility, and the field of statistical demography are explored.

  2. Age-Related Reversal of Postural Adjustment Characteristics During Motor Imagery

    PubMed Central

    2016-01-01

    Physical and imagined movements show similar behavioral constraints and neurophysiological activation patterns. An inhibition mechanism is thought to suppress overt movement during motor imagery, but it does not effectively suppress autonomic or postural adjustments. Inhibitory processes and postural stability both deteriorate with age. Thus, older people’s balance is potentially vulnerable to interference from postural adjustments induced by thoughts about past or future actions. Here, young and older adults stood upright and executed or imagined manual reaching movements. Reported arm movement time (MT) of all participants increased with target distance. Older participants reported longer MT than young participants when executing arm movements, but not when imagining them. Older adults’ anteroposterior (AP) and mediolateral (ML) postural sway was higher than young adults’ at baseline, but their AP sway fell below their baseline level during manual imagery. In contrast, young adults’ AP sway increased during imagery relative to their baseline. A similar tendency to reduce sway in the ML direction was also observed in older adults during imagery in a challenging stance. These results suggest that postural response during manual motor imagery reverses direction with age. Motor imagery and action planning are ubiquitous tasks, and older people are likely to spend more time engaged in them. The shift toward restricting body sway during these tasks is akin to a postural threat response, with the potential to interfere with balance during activities of daily living. PMID:27808526

  3. Use of age-adjusted rates of suicide in time series studies in Israel.

    2009-01-01

    Durkheim's modified theory of suicide was examined to explore how consistent it was in predicting Israeli rates of suicide from 1965 to 1997 when using age-adjusted rates rather than crude ones. In this time-series study, Israeli male and female rates of suicide increased and decreased, respectively, between 1965 and 1997. Conforming to Durkheim's modified theory, the Israeli male rate of suicide was lower in years when rates of marriage and birth are higher, while rates of suicide are higher in years when rates of divorce are higher, the opposite to that of Israeli women. The corrected regression coefficients suggest that the Israeli female rate of suicide remained lower in years when rate of divorce is higher, again the opposite suggested by Durkheim's modified theory. These results may indicate that divorce affects the mental health of Israeli women as suggested by their lower rate of suicide. Perhaps the "multiple roles held by Israeli females creates suicidogenic stress" and divorce provides some sense of stress relief, mentally speaking. The results were not as consistent with predictions suggested by Durkheim's modified theory of suicide as were rates from the United States for the same period nor were they consistent with rates based on "crude" suicide data. Thus, using age-adjusted rates of suicide had an influence on the prediction of the Israeli rate of suicide during this period.

    Background Schistosomiasis is a water-based disease that is believed to affect over 200 million people with an estimated 97% of the infections concentrated in Africa. However, these statistics are largely based on population re-adjusted data originally published by Utroska and colleagues more than 20 years ago. Hence, these estimates are outdated due to large-scale preventive chemotherapy programs, improved sanitation, water resources development and management, among other reasons. For planning, coordination, and evaluation of control activities, it is essential to possess reliable schistosomiasis prevalence maps. Methodology We analyzed survey data compiled on a newly established open-access global neglected tropical diseases database (i) to create smooth empirical prevalence maps for Schistosoma mansoni and S. haematobium for individuals aged ≤20 years in West Africa, including Cameroon, and (ii) to derive country-specific prevalence estimates. We used Bayesian geostatistical models based on environmental predictors to take into account potential clustering due to common spatially structured exposures. Prediction at unobserved locations was facilitated by joint kriging. Principal Findings Our models revealed that 50.8 million individuals aged ≤20 years in West Africa are infected with either S. mansoni, or S. haematobium, or both species concurrently. The country prevalence estimates ranged between 0.5% (The Gambia) and 37.1% (Liberia) for S. mansoni, and between 17.6% (The Gambia) and 51.6% (Sierra Leone) for S. haematobium. We observed that the combined prevalence for both schistosome species is two-fold lower in Gambia than previously reported, while we found an almost two-fold higher estimate for Liberia (58.3%) than reported before (30.0%). Our predictions are likely to overestimate overall country prevalence, since modeling was based on children and adolescents up to the age of 20 years who are at highest risk of infection.

    1998-08-01

    During 1991 and 1992, 2,800 market-age pigs were sampled at federally inspected abattoirs from across Canada. Anti-Toxoplasma gondii IgG at titers of > or =1:32 were found in 240 pigs examined by a commercial, latex agglutination test. Seroprevalences ranged from 3.5 to 13.2% in the different regions of the country. Tissue hybridization studies using a previously developed probe demonstrated T. gondii ribosomal RNA in 9 of 36 animals, whereas mouse bioassay testing of heart muscle and diaphragm from all 2,800 pigs failed to demonstrate the presence of infective stages of T. gondii in tissues. Although serology results from this study indicated that Canadian market-age pigs are infected with T. gondii at rates similar to those reported from other parts of North America, mouse bioassay results suggested that Canadian pork products contain low levels of infective organisms. This apparent discrepancy suggests that serological evidence of T. gondii infection in pigs alone does not accurately assess the public health risks associated with consuming improperly cooked pork products.

    Recent theories have proposed a metastructure that organizes related mental disorders into broad dimensions of psychopathology (i.e., internalizing and externalizing dimensions). Prevalence rates of most mental disorders, when examined independently, are substantially lower in older than in younger adults, which may affect this metastructure. Within a nationally representative sample, the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; N = 43,093), we developed a dimensional liability model of common psychiatric disorders to clarify whether aging affects specific disorders or general dimensions of psychopathology. Significant age differences existed across age groups (18-24, 25-34, 35-44, 45-54, 55-64, 65-75 and 75+), such that older adults showed lower prevalence rates of most disorders compared to younger adults. We next investigated patterns of disorder comorbidity for past-year psychiatric disorders and found that a distress-fear-externalizing liability model fit the data well. This model was age-group invariant and indicated that the observed lower prevalence of mental disorders with advancing age originates from lower average means on externalizing and internalizing liability dimensions. This unifying dimensional liability model of age and mental disorder comorbidity can help inform the role of aging on mental disorder prevalence for research and intervention efforts, and service planning for the impending crisis in geriatric mental health.

    Background. Infection with Chlamydia trachomatis (CT) can lead to reproductive sequelae. Information on the general population of childbearing age women in India is sparse. We reviewed the literature on CT prevalence within the general population of reproductive aged women in order to improve the efforts of public health screening programs and interventions. Objective. To conduct a literature review to determine the prevalence of Chlamydia trachomatis among childbearing age women in India. Search Strategy. Ovid Medline and PubMed databases were searched for articles from January 1, 2003, through December 31, 2014. Search terms included “Chlamydia trachomatis”, “CT”, “prevalence”, “India”, and “sexually transmitted infections”. Selection Criteria. Studies on prevalence data for CT among women of childbearing age (15–45) living in India were included. Data Collection and Analysis. Articles that met the inclusion criteria were extracted by two readers and discrepancies solved through discussion. Results. Reported prevalence of active CT infection among lower risk groups ranged from 0.1% to 1.1% and in higher risk group from 2.7% to 28.5%. Conclusion. CT prevalence among women in India is comparable to other countries. Screening programs to prevent adverse outcomes among Indian women of childbearing age and their offspring are warranted.

    PubMed Central

    Chinn, S; Rona, R J

    1992-01-01

    BACKGROUND: No standard exists for the adjustment of lung function for height and age in children. Multiple regression should not be used on untransformed data because, for example, forced expiratory volume (FEV1), though normally distributed for height, age, and sex, has increasing standard deviation. A solution to the conflict is proposed. METHODS: Spirometry on representative samples of children aged 6.5 to 11.99 years in primary schools in England. After exclusion of children who did not provide two repeatable blows 910 white English boys and 722 girls had data on FEV1 and height. Means and standard deviations of FEV1 divided by height were plotted to determine whether logarithmic transformation of FEV1 was appropriate. Multiple regression was used to give predicted FEV1 for height and age on the transformed scale; back transformation gave predicted values in litres. Other lung function measures were analysed, and data on inner city children, children from ethnic minority groups, and Scottish children were described. RESULTS: After logarithmic (ln) transformation of FEV1 standard deviation was constant. The ratios of actual and predicted values of FEV1 were normally distributed in boys and girls. From the means and standard deviations of these distributions, and the predicted values, centiles and standard deviation scores can be calculated. CONCLUSION: The method described is valid because the assumption of stable variance for multiple regression was satisfied on the log scale and the variation of ratios of actual to predicted values on the original scale was well described by a normal distribution. The adoption of the method will lead to uniformity and greater ease of comparison of research findings. PMID:1440464

    2015-07-01

    The aging of the workforce in the developed world has prompted organizations to implement human resource (HR) policies and practices encouraging older workers to defer retirement. However, little is known about the prevalence of such practices, and the organizational factors associated with their adoption. In this study, we used data collected from 2008 to 2009 from a national probability sample of retirement eligible workers in the United States (N = 407) to assess the prevalence of aging-friendly human resource practices (AFHRP), and their organizational predictors. Results indicate that employee wellness programs, unpaid leave, and reassignment based on physical needs are among the most prevalent AFHRP. However, in the vast majority of enterprises, AFHRP are limited. Results also indicate that projected organizational growth and a focus on internal labor market practices are positively associated with the adoption of AFHRP. Organizational size and the degree of unionization, while positively associated with aging-friendly benefits, were inversely associated with flexibility practices.

    This article describes new relationships between the age-specific incidence of, the prevalence of and mortality from a chronic disease. We express these relationships in terms of an ordinary differential equation and form the methodological basis for a novel approach to estimating incidences from age-specific prevalence data. We examine practical aspects of the relationships and a comparison with a known stochastic method in a simulation study. Finally, we apply the novel method to a data set of renal replacement therapy recorded from patients with chronic kidney failure in a region of Germany with approximately 310,000 inhabitants from 2002 to 2010.

    Objectives. We evaluated the effect of neighborhood disadvantage (ND) on older adults’ prevalence, awareness, treatment, and control of hypertension. Methods. Data were from the University of Alabama at Birmingham Study of Aging, an observational study of 1000 community-dwelling Black and White Alabamians aged 65 years and older, in 1999 to 2001. We assessed hypertension prevalence, awareness, treatment, and control with blood pressure measurements and self-report data. We assessed ND with US Census data corresponding with participants’ census tracts, created tertiles of ND, and fit models with generalized estimating equations via a logit link function with a binomial distribution. Adjusted models included variables assessing personal advantage and disadvantage, place-based factors, sociodemographics, comorbidities, and health behaviors. Results. Living in mid-ND (adjusted odds ratio [AOR] = 1.6; 95% confidence interval [CI] = 1.2, 2.1) and high-ND tertiles (AOR = 1.8; 95% CI = 1.3, 2.3) was associated with higher hypertension prevalence, and living in high-ND tertiles was associated with lower odds of controlled hypertension (AOR = 0.6; 95% CI = 0.4, 0.6). In adjusted models, ND was not associated with hypertension awareness or treatment. Conclusions. These findings show that neighborhood environmental factors matter for hypertension outcomes and suggest the importance of ND for hypertension management in older adults. PMID:25322309

    The goal of the study was twofold: (1) to investigate the effect of different diagnostic criteria on prevalence estimates of adult attention deficit hyperactivity disorder (ADHD), and (2) to provide prevalence estimates of adult ADHD for the first time in a Hungarian sample. Subjects between 18 and 60 years were included in the screening phase of the study (N = 3,529), conducted in 17 GP practices in Budapest. Adult self-report scale 6-item version was used for screening. Out of 279 positively screened subjects 161 subjects participated in a clinical interview and filled out a self-report questionnaire to confirm the diagnosis. Beside DSM-IV diagnostic criteria, we applied four alternative diagnostic criteria: 'No-onset' (DSM-IV criteria without the specific requirement for onset); full/Sx (DSM-IV "symptoms only" criteria); and reduced/Sx (DSM-IV "symptoms only" criteria with a reduced threshold for symptom count). Crude prevalence estimates adjusted for the specificity and sensitivity data of the screener were 1.35% in the 'DSM-IV' group, 1.64% in the 'No-onset' group, 3.65% in the 'Sx/full' group and 4.16% in the 'Sx/reduced' group. Logistic regression analysis showed that ADHD was significantly more prevalent with younger age and male gender [chi(2) = 14.46; P = 0.0007]. Prevalence estimates corrected for the 'not-interviewed' subsample and adjusted for specificity and sensitivity data of the screener was 2.3% in males, 0.91% in females; 2.02% in the < or =40 years age group and 0.70% in the >40 years age group, based on DSM-IV diagnostic criteria. Prevalence rates found in this study are somewhat lower, but still are in line with those reported in the literature.

    Objective To describe the prevalence of multimorbidity involving 20 selected chronic conditions in a geographically defined US population, emphasizing age, sex, and ethnic differences. Patients and Methods Using the Rochester Epidemiology Project (REP) records-linkage system, we identified all residents of Olmsted County, MN on April 1, 2010, and we electronically extracted the International Classification of Diseases, ninth revision (ICD-9) codes associated with all healthcare visits made between April 1, 2005 and March 31, 2010 (5-year capture frame). Using these ICD-9 codes, we defined the 20 common chronic conditions recommended by the US Department of Health and Human Services. We counted only persons who received at least two codes for a given condition separated by more than 30 days, and calculated the age-, sex-, and ethnicity-specific prevalence of multimorbidity. Results Of the 138,858 study subjects, 52.4% were women, 38.9% had one or more conditions, 22.6% had two or more, and 4.9% had 5 or more conditions. The prevalence of multimorbidity (2 or more conditions) increased steeply with older age and reached 77.3% at ages 65 years and older. However, the absolute number of people affected by multimorbidity was higher in those younger than 65 years. Although the prevalence of multimorbidity was similar in men and women overall, the most common dyads and triads of conditions varied by sex. Compared to Whites, the prevalence of multimorbidity was slightly higher in Blacks and slightly lower in Asians. Conclusion Multimorbidity is common in the general population; it increases steeply with older age, has different patterns in men and women, and varies by ethnicity. PMID:25220409

    OBJECTIVE: To estimate the prevalence of dementia and its subtypes by sex and age group for five regions of Canada. DESIGN: Prevalence survey. SETTING: Community and institutional settings in Canada, excluding those in the two territories, Indian reserves and military units. PARTICIPANTS: Representative sample of people aged 65 and over interviewed between February 1991 and May 1992. Those in the community (9008 subjects) were chosen randomly from medicare lists in nine provinces or from the Enumeration Composite Record in Ontario. People in institutions (1255) were randomly selected from residents in stratified random samples of institutions in each region. INTERVENTIONS: Screening with the Modified Mini-Mental State (3MS) Examination to identify cognitive impairment. Clinical examination of all those in institutions, those in the community with a 3MS score of less than 78 and a sample of those in the community with a 3MS score of 78 or more to diagnose dementia. Dementia and Alzheimer's disease were defined according to established criteria. MAIN OUTCOME MEASURES: Prevalence of dementia of all types, by region, sex and age group, the estimated number of cases in the population by type of dementia and the age-standardized rate per 1000 population. RESULTS: The prevalence estimates suggested that 252,600 (8.0%) of all Canadians aged 65 and over met the criteria for dementia (95% confidence interval [CI] 236,800 to 268,400). These were divided roughly equally between the community and institutional samples; the female:male ratio was 2:1. The age-standardized rate ranged from 2.4%, among those aged 65 to 74 years, to 34.5%, among those aged 85 and over. The corresponding figures for Alzheimer's disease were 5.1% overall (161,000 cases; 95% CI 148,100 to 173,900), ranging from 1.0% to 26.0%; for vascular dementia it was 1.5% overall, ranging from 0.6% to 4.8%. If the prevalence estimates remain constant, the number of Canadians with dementia will rise to 592,000 by

    Prevalence of atopic dermatitis (AD) is increasing worldwide. Up to date, there has been no face-to-face nation-wide study in China. We aim to explore the prevalence of clinical diagnosed AD in children aged 1–7 ys in China. Twelve metropolises were chosen from different areas of China. In each region, we selected 4–10 kindergartens and 2–5 vaccination clinics randomly. A complete history-taking and skin examination were performed by dermatologists. The definite diagnosis of AD and the severity were determined by two or three dermatologists. All criteria concerned in UK diagnosis criteria, characteristic presentation of AD and atypical manifestations were recorded in detail. A total of 13998 children from 84 kindergartens and 40 vaccination clinics were included. The prevalence of AD was 12.94% by clinical diagnosis of dermatologists overall, with 74.6% of mild AD. Comparatively, prevalence of AD based on UK diagnostic criteria was 4.76%. This is the first face-to-face nation-wide study in Chinese children aged 1–7 ys, revealing that the prevalence of AD in children is closer to that of wealthier nations. PMID:27432148

    Summary Objectives Recent studies in Central America indicate that mortality attributable to chronic kidney disease (CKD) is rising rapidly. We sought to determine the prevalence and regional variation of CKD and the relationship of biologic and socioeconomic factors to CKD risk in the older-adult population of Costa Rica. Methods We used data from the Costa Rican Longevity and Health Aging Study (CRELES). The cohort was comprised of 2657 adults born before 1946 in Costa Rica, chosen through a sampling algorithm to represent the national population of Costa Ricans >60 years of age. Participants answered questionnaire data and completed laboratory testing. The primary outcome of this study was CKD, defined as an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73m2. Results The estimated prevalence of CKD for older Costa Ricans was 20% (95% CI 18.5 – 21.9%). In multivariable logistic regression, older age (adjusted odds ratio [aOR] 1.08 per year, 95%CI 1.07–1.10, p<0.001) was independently associated with CKD. For every 200 meters above sea level of residence, subjects’ odds of CKD increased 26% (aOR 1.26 95% CI 1.15–1.38, p<0.001). There was large regional variation in adjusted CKD prevalence, highest in Limon (40%, 95% CI 30%–50%) and Guanacaste (36%, 95% CI 26–46%) provinces. Regional and altitude effects remained robust after adjustment for socioeconomic status. Conclusions We observed large regional and altitude-related variations in CKD prevalence in Costa Rica, not explained by the distribution of traditional CKD risk factors. More studies are needed to explore the potential association of geographic and environmental exposures with the risk of CKD. PMID:26466575

    Aim To examine age and gender differences in the prevalence and incidence of child sexual abuse, the level of acquaintance of the child and the perpetrator, and correlations between experiencing family violence and sexual abuse on a nationally representative sample of 11, 13, and 16 years old children. Method A probabilistic stratified cluster sample included 2.62% of the overall population of children aged 11 (n = 1223), 13 (n = 1188), and 16 (n = 1233) from 40 primary and 29 secondary schools. A modified version of ISPCAN Child Abuse Screening Tool – Children's Version was used. Five items referred to child sexual abuse (CSA) for all age groups. Results In Croatia, 10.8% of children experienced some form of sexual abuse (4.8% to 16.5%, depending on the age group) during childhood and 7.7% of children experienced it during the previous year (3.7% to 11.1%, depending on the age group). Gender comparison showed no difference in the prevalence of contact sexual abuse, whereas more girls than boys experienced non-contact sexual abuse. Correlations between sexual abuse and physical and psychological abuse in the family were small, but significant. Conclusion Comparisons with international studies show that Croatia is a country with a low prevalence of CSA. The fact that the majority of perpetrators of sexual abuse are male and female peers indicates the urgent need to address risks of sexual victimization in the health education of children.

    Many infections cause lasting detectable immune responses, whose prevalence can be estimated from cross-sectional surveys. However, such surveys do not provide direct information on the incidence of infection. We address the issue of estimating age and time specific incidence from a series of prevalence surveys under the assumption that incidence changes exponentially with time, but make no assumption about the age specific incidence. We show that these assumptions lead to a proportional hazards model and estimate its parameters using semi-parametric maximum likelihood methods. The method is applied to tuberculin surveys in The Netherlands to explore age dependence of the risk of tuberculous infection in the presence of a strong secular decline in this risk.

    Compensatory steps are essential for preventing falls following perturbations. This study aimed to explore age-related changes in compensatory steps to unilateral perturbations, specifically in terms of whether anticipatory postural adjustments (APAs) play a role in stabilizing lateral balance. Five young and five elderly male adults participated. The split-belt treadmill was used to provide bi- and unilateral perturbations, as forward or backward transitions, applied 10 times in random order. Backward steps evoked by unilateral forward perturbations were evaluated. We measured temporal characteristics, mediolateral (ML) center of mass (COM) motion, and ML step length of compensatory steps. Compensatory steps to unexpected perturbations showed delayed onset of foot-off (FO) and expanded lateral swing length in elderly compared to young subjects. Differences in COM motions and step width arose related to APAs. Elderly subjects showing APAs exhibited no significant differences in ML COM, ML COM velocity, or ML swing length compared to young subjects. However, elderly subjects without APAs showed significant changes toward instability in these parameters. The fact that APAs play a notable role, particularly in the elderly, in stability offers a new insight into preventing falls. However, APAs occurred in 29% of the steps of young and 35% of the steps of elderly subjects. If the occurrence of APAs in elderly people in response to compensatory steps was more frequent, fall risk would be reduced. Further studies, particularly into APA frequency, might contribute to improved intervention to prevent falls.

    Centenarians and their offspring are increasingly considered a useful model to study and characterize the mechanisms underlying healthy aging and longevity. The aim of this project is to compare the prevalence of age-related diseases and telomere length (TL), a marker of biological age and mortality, across five groups of subjects: semisupercentenarians (SSCENT) (105-109years old), centenarians (CENT) (100-104years old), centenarians' offspring (CO), age- and gender-matched offspring of parents who both died at an age in line with life expectancy (CT) and age- and gender-matched offspring of both non-long-lived parents (NLO). Information was collected on lifestyle, past and current diseases, medical history and medication use. SSCENT displayed a lower prevalence of acute myocardial infarction (p=0.027), angina (p=0.016) and depression (p=0.021) relative to CENT. CO appeared to be healthier compared to CT who, in turn, displayed a lower prevalence of both arrhythmia (p=0.034) and hypertension (p=0.046) than NLO, characterized by the lowest parental longevity. Interestingly, CO and SSCENT exhibited the longest (p<0.001) and the shortest (p<0.001) telomeres respectively while CENT showed no difference in TL compared to the younger CT and NLO. Our results strengthen the hypothesis that the longevity of parents may influence the health status of their offspring. Moreover, our data also suggest that both CENT and their offspring may be characterized by a better TL maintenance which, in turn, may contribute to their longevity and healthy aging. The observation that SSCENT showed considerable shorter telomeres compared to CENT may suggest a progressive impairment of TL maintenance mechanisms over the transition from centenarian to semisupercentenarian age.

    We investigated the prevalence of peptic ulcer in dyspeptic patients in China to analyze the influence of age, sex, and Helicobacter pylori (H. pylori) infection. The results showed that the prevalence of gastric and duodenal ulcer increased with age. In patients under 60 years old, the prevalence of duodenal and gastric ulcers in females was markedly lower than that in males, especially the prevalence of duodenal ulcer. The prevalence of duodenal ulcer and gastric ulcer in H. pylori-infected patients was markedly higher than in patients without H. pylori infection. In the patients under 60 years old, sex differences were still seen in both H. pylori-positive and H. pylori-negative patients. The prevalence of gastric and duodenal ulcers was markedly increased with age in both H. pylori-positive and H. pylori-negative patients. Multivariate logistic regression analysis showed that age, male sex, and H. pylori infection were three independent risk factors for gastric and duodenal ulcers.

    The physiological processes of ageing and factors prevalent in the elderly such as comorbidities and polypharmacy often cause loss of appetite in the elderly, which we call anorexia of ageing. Social factors, together with changes in the sensory organs, can be important causes of a reduction in both appetite and ingestion. This review assesses the regulation of appetite in the elderly and the development of anorexia of ageing. It also examines the prevalence of this type of anorexia, its associated comorbidities and mortality rates. We have reviewed 27 studies, with a total of 6208 patients. These reported changes in the secretion and response of both central and peripheral hormones that regulate appetite. Anorexia, very prevalent among hospitalized and institutionalized elderly people, is associated with comorbidity and represents a predictive factor for mortality. No treatment for it has been proved to be effective. The mechanism regulating ingestion in elderly people is complex and difficult to resolve. Comorbidity as a cause or a consequence of anorexia of ageing has become a research field of great interest in geriatrics. A correct nutritional evaluation is a fundamental part of an integrated geriatric assessment.

    This study aimed to (i) assess the prevalence and perceived need for treatment of TMD pain, and its association with socio-economic factors and gender, in adolescents in Xi᾽an, Shaanxi Province, China, and (ii) compare the prevalence and association with gender of TMD pain in Xi᾽an to an age-matched Swedish population. We surveyed Chinese adolescents aged 15 to 19 years in Xi'an, China (n = 5524), using a questionnaire with two-stage stratified sampling and the school as the sampling unit. The study included second-year students at selected high schools. It also included an age-matched Swedish population (n = 17,015) surveyed using the same diagnostic criteria for TMD pain as that used in the Chinese sample. The survey found TMD pain in 14·8% (n = 817) of the Chinese sample and 5·1% (n = 871) of the Swedish sample (P < 0·0001). Girls had significantly more TMD pain than boys in both the Chinese (P < 0·05) and Swedish (P < 0·001) samples. TMD pain increased with age in the Chinese population. Of the Chinese adolescents with TMD pain, 47% reported that they felt a need for treatment. Rural schools, low paternal education levels, poverty, living outside the home, poor general and oral health, and dissatisfaction with teeth all showed significant positive correlations with TMD pain. Prevalence of TMD pain in Chinese adolescents was significantly higher than in the Swedish sample.

    Background Estimating the burden of healthcare-associated infections (HAIs) compared to other communicable diseases is an ongoing challenge given the need for good quality data on the incidence of these infections and the involved comorbidities. Based on the methodology of the Burden of Communicable Diseases in Europe (BCoDE) project and 2011–2012 data from the European Centre for Disease Prevention and Control (ECDC) point prevalence survey (PPS) of HAIs and antimicrobial use in European acute care hospitals, we estimated the burden of six common HAIs. Methods and Findings The included HAIs were healthcare-associated pneumonia (HAP), healthcare-associated urinary tract infection (HA UTI), surgical site infection (SSI), healthcare-associated Clostridium difficile infection (HA CDI), healthcare-associated neonatal sepsis, and healthcare-associated primary bloodstream infection (HA primary BSI). The burden of these HAIs was measured in disability-adjusted life years (DALYs). Evidence relating to the disease progression pathway of each type of HAI was collected through systematic literature reviews, in order to estimate the risks attributable to HAIs. For each of the six HAIs, gender and age group prevalence from the ECDC PPS was converted into incidence rates by applying the Rhame and Sudderth formula. We adjusted for reduced life expectancy within the hospital population using three severity groups based on McCabe score data from the ECDC PPS. We estimated that 2,609,911 new cases of HAI occur every year in the European Union and European Economic Area (EU/EEA). The cumulative burden of the six HAIs was estimated at 501 DALYs per 100,000 general population each year in EU/EEA. HAP and HA primary BSI were associated with the highest burden and represented more than 60% of the total burden, with 169 and 145 DALYs per 100,000 total population, respectively. HA UTI, SSI, HA CDI, and HA primary BSI ranked as the third to sixth syndromes in terms of burden of disease

    2011-01-01

    Background In June 2001, the United Nations General Assembly Special Session (UNGASS) set a target of reducing HIV prevalence among young women and men, aged 15 to 24 years, by 25% in the worst-affected countries by 2005, and by 25% globally by 2010. We assessed progress toward this target in Manicaland, Zimbabwe, using repeated household-based population serosurvey data. We also validated the representativeness of surveillance data from young pregnant women, aged 15 to 24 years, attending antenatal care (ANC) clinics, which UNAIDS recommends for monitoring population HIV prevalence trends in this age group. Changes in socio-demographic characteristics and reported sexual behaviour are investigated. Methods Progress towards the UNGASS target was measured by calculating the proportional change in HIV prevalence among youth and young ANC attendees over three survey periods (round 1: 1998-2000; round 2: 2001-2003; and round 3: 2003-2005). The Z-score test was used to compare differences in trends between the two data sources. Characteristics of participants and trends in sexual risk behaviour were analyzed using Student's and two-tailed Z-score tests. Results HIV prevalence among youth in the general population declined by 50.7% (from 12.2% to 6.0%) from round 1 to 3. Intermediary trends showed a large decline from round 1 to 2 of 60.9% (from 12.2% to 4.8%), offset by an increase from round 2 to 3 of 26.0% (from 4.8% to 6.0%). Among young ANC attendees, the proportional decline in prevalence of 43.5% (from 17.9% to 10.1%) was similar to that in the population (test for differences in trend: p value = 0.488) although ANC data significantly underestimated the population prevalence decline from round 1 to 2 (test for difference in trend: p value = 0.003) and underestimated the increase from round 2 to 3 (test for difference in trend: p value = 0.012). Reductions in risk behaviour between rounds 1 and 2 may have been responsible for general population prevalence declines

    To determine the prevalence of caregiver-reported asthma in children 4 to 13 years old in metropolitan western New York State, surveys were conducted during 1997-1999 in the Buffalo, Niagara Falls, Iroquois, and Gowanda school systems. Questionnaires (3,889) were sent to the homes of elementary school children in nine schools in western New York. The caregivers were asked to complete a 13-item questionnaire for the child. Of the questionnaires, 60.5% (2,353/3,889) were completed. Of all children, 18% had physician-diagnosed asthma. Of children diagnosed with asthma, 86% were taking medication. Symptoms were consistent with suspected undiagnosed asthma for 13% of the children. Buffalo had the highest rate of diagnosed asthma (20%) for the age group. Gowanda had a prevalence of 18%, Iroquois 16%, and Niagara Falls 15%. Variations were observed in asthma prevalence rates among different racial/ethnic groups. In general, boys had a significantly (P = .001) increased odds of being asthmatic compared with girls. Overall, African-Americans and Hispanic/Latino children had significantly (P = .012 and P = .005, respectively) higher asthma prevalence rates, two to five times those of their Caucasian peers. In Gowanda, the prevalence of diagnosed asthma among Native American children was 23%, compared to 15% among Caucasian children. Of diagnosed Native American children, 71% were female. In Gowanda, a significant association (P = .007) of asthma among children in split-grade classes was observed compared to nonsplit grades. Of Native American children in split grades, 60% were diagnosed asthmatics. These observations reveal a high prevalence of asthma in the age group of 4 to 13 year olds in western New York. Local variations in potential triggers of asthma need to be considered when advising asthmatics. The results suggest that some grades have a disproportionate amount of children with asthma. The implications of asthma for children's early education need to be examined

    PurposeTo report the age- and gender-adjusted prevalence rates of early and late age-related maculopathy (ARM) and associated risk factors in rural and urban Indian population.MethodsA population-based cross-sectional study was carried out in South India between 2009 and 2011. Of the 6617 subjects ≥60 years enumerated ones, 5495 (83.04%) participated in the eye examination. A detailed history including data on demographic, socioeconomic, and ocular history was obtained. Participants underwent detailed ophthalmic evaluation including 30° 3-field photograph as per Age-Related Eye Disease Study protocol. The ARM was graded according to the International ARM Epidemiological Study Group.ResultsAge- and gender-adjusted prevalence of early ARM was 20.91% (20.86-20.94) in the rural population and 16.37% (16.32-16.42) in the urban population. Similarly, the prevalence of late ARM was 2.26% (2.24-2.29) and 2.32% (2.29-2.34) in the rural and urban population, respectively. In both rural and urban populations, risk factors that were related to both early and late ARM were age, per year increase (OR, range 1.00-1.08); middle socioeconomic status (OR, range 1.05-1.83); and smokeless tobacco (OR, range 1.11-2.21). Protective factor in both was the presence of diabetes mellitus in all ARM (OR, range 0.34-0.83). Risk factors, only in the rural arm, were female gender (OR, range 1.06-1.64), past smoker (OR, 1.14), and serum low-density lipoprotein cholesterol level (OR, 1.03).ConclusionsThe study reports smokessless tobacco as a risk factor for both early and late ARM and identified a higher prevalence of early ARM in the rural population compared with urban population.

    Bullying among school-aged youth is a common issue worldwide and is increasingly being recognized as an important problem affecting both victims and perpetrators. Most of the bullying studies have been conducted in western countries, and their implications in other regions are limited due to different cultural contexts. The goal of our study is to identify the prevalence of bullying and its correlates school-aged youth in Guangdong province. In total, 1098 (7.1%) students reported having bullied other students, 744 (4.8%) students reported having been bullied by other students and 396 (2.6%) students reported having both bullied other students and been bullied by other students. There was a strong association between bullying others as well as being bullied and suicidal ideations, suicidal attempts, and self-harm behaviors. The prevalence of bullying and its associations with delinquent behaviors warrant the importance of school facility based preventive intervention taking into account both victims and perpetrators.

    Dizziness has been reported to be preponderant among the elderly people, however, little is known about the prevalence and risk factors in the sub Saharan population. This longitudinal cohort study determines the prevalence of dizziness and the clinical and socio-epidemiological correlates in elderly persons residing in the Yoruba-speaking areas of Nigeria. Dizziness was reported 318/1299, representing a prevalence of 24.6%. They were made up of 197(58.5%) females and 121(41.5%) males, 39 (27.6%) were in the 65-69 years age range, 91 in the 70-74years age range, 66(26.8%) in the 75-79 years and 122(45.5%) were above 80 years. The majority of the subjects (253/318) (%) lived in rural-sub-urban, with no formal education in (172/318) (%) and more than two-third (213/318) were of low economic status. Balance test conducted in 1, 006 elderly subjects revealed poor balance (mean balance test score <3.3) in 93/250(37.2%) subjects with dizziness and 189/756(25%) subjects without dizziness(P=0.01). Logistic regression adjusting for age and gender revealed that the odds for poor balance were 1.5 times greater in elderly with dizziness. Low economic status (P=0.05) and smoking (P=0.01) were found to be significant in univariate analysis while logistic regression revealed smoking(OR=1.51, CI=1.17-1.95, P=0.01) and gender(OR=0.77, CI=0.59-0.99, P=0.05) as significant correlate of dizziness while none of age, residence or educational level was significant. Significant clinical correlates in the experience of dizziness included self report of suppurative otitis media (OR =2.07, CI=1.21- 3.52, P=0.01), head injury (OR=2.41, CI=1.61-3.61, P=0.00), recurrent rhinosinusitis (OR=2.97, CI=2.05-4.29,P=0.00), current hypertension(OR=1.43, CI=1.03-2.00, P=0.03) and transient ischemic attack(OR=1.97, CI=1.19-3.23, P=0.01), while diabetes mellitus(OR=1.50, CI= 0.83- 2.71, P= 0.18) was not.

    This study had three purposes: (a) to compare the prevalence of boys' and girls' gender-atypical behaviors (GABs) in a sample of Chinese school-aged children, (b) to examine the developmental pattern of GABs in Chinese boys and girls over the age range in question (6-12 years), and (c) to test the effects of being an only child on children's GAB expression. Parents of 486 boys and 417 girls completed a Child Play Behavior and Activity Questionnaire (CPBAQ) in regard to their own children, and a demographic information sheet. The frequency distribution for each gender-related behavior was calculated. The associations between sex, age, and only-child status, and CPBAQ scale scores were examined. Although most GABs (by their very nature) were exhibited infrequently in Chinese children, it was found that girls displayed GABs more frequently than boys did. The prevalence of GABs rose for girls as they grew older, but fell slightly for boys. The expressions of GABs in only children did not differ from that in children with siblings. Possible effects of Chinese culture (including the current only-child policy) on children's GABs are discussed.

    To investigate the potential relationship between age and diagnosis of cystic endometrial hyperplasia (CEH) in the bitches, 348 ultrasound examinations from 240 bitches (Labradors, Golden Retrievers, German Shepherds, Flat Coated Retrievers, or crosses of those breeds aged between 1.6 and 7.2 years at examination) were examined. A subpopulation of 32 bitches that had completed their breeding careers at 6 years or more of age was also identified. Of all, 18.3% of the bitches were diagnosed with CEH; these cases were newly diagnosed when bitches were between 2.5 years and 7.3 years of age. The proportion of ultrasound examinations in which CEH was identified increased from 6.8% of examinations on 2-year-old breeding bitches to 60.0% of examinations on 6-year-old bitches. Logistic regression identified a positive correlation between mean age at the examination and presence of CEH (χ(2) = 30.74, degrees of freedom = 1, P < 0.001). For 32 bitches that had completed their breeding career, the prevalence of CEH was 56.3%, age at the diagnosis ranged from 3.8 to 7.3 years, and the proportion of bitches affected with CEH increased from 6.3% at 3 years of age to 56.3% at 7 years of age. These data support the contention that the prevalence of CEH increases with age.

    Early acquisition of hepatitis C virus (HCV) infection appears to affect a substantial proportion of injection drug users (IDUs)--between 20 percent and 90 percent. Analysing the range of HCV prevalence estimates in new injectors may help identify factors that can be modified to reduce HCV transmission. The HCV Synthesis Project is a meta-analysis of studies of HCV epidemiology and prevention in drug users worldwide. In this preliminary analysis, we examined data from 127 studies of IDUs that reported HCV prevalence in relation to age or year since onset of drug injection, analysing heterogeneity and calculating summary statistics where appropriate. Six studies reported gender-specific HCV prevalence rates among young or new injectors; the group mean prevalence was 47 percent for men and 44 percent for women (NS). Group mean age for HCV-negatives was 24.7 years (range 24-28) and 26.1 years (range 21-31) for HCV-positives (n=8 studies). Data were examined from 13 studies that compared HCV prevalence among young injectors to older injectors using 5-year age categories; substantial variation was present within these categories such that measures of central tendency were not calculated. Similarly, among studies reporting HCV prevalence among IDUs in relation to 1-year intervals of duration of injection (<1 year, <2 years, and <3 years), considerable variability was observed. Notably, there were studies in each category that reported prevalence of 70 percent or higher among recent-onset drug injectors. Our findings confirm previous studies reporting high risk of acquiring HCV shortly after onset of injection; thus, HCV prevention programmes must emphasize methods to reach new injectors. Future research should (1) report data on time to infection in depth, (2) provide detailed information on study methodology, and (3) characterize the research setting with respect to underlying factors that affect injection practices and networks. This will permit synthesis of a greater

    OBJECTIVE: To determine the prevalence of vitamin A deficiency in children aged 6-9 years in northern Ethiopia. METHODS: A cross-sectional study was carried out and the data were analysed for 824 (61.5%) of 1339 eligible children for whom there was complete information on biochemical vitamin A status, dietary vitamin A intake, ocular examination for xerophthalmia, and anthropometry. FINDINGS: The prevalence of xerophthalmia was 5.8%; serum retinol levels were below 0.35 mumol/l and between 0.35 and 0.70 mumol/l in 8.4% and 51.1% of the children respectively. The liver vitamin A reserve (modified relative dose response ratio > or = 0.06) was low in 41.0% of the children. CONCLUSION: The high prevalence of severe vitamin A deficiency in children aged 6-9 years indicates the need to reevaluate the practice of targeting vitamin A supplementation programmes on children under 6 years of age in areas where vitamin A deficiency is endemic.

    Hypertension and its sequelae complicate pregnancy and can result in poor perinatal outcomes. Overall, U.S. blacks are more likely to be hypertensive than whites, but the degree to which this is true among women of childbearing age (including teenagers) is unknown. Using data from the second National Health and Nutrition Examination Survey (NHANES II), the authors describe hypertension prevalence rates for 422 black and 2,700 white reproductive-age women. The authors present observed data and also predicted prevalence rates derived by modeling the odds of hypertension using logistic regression statistical techniques. They find that black-white differences in hypertension prevalence are negligible among teenagers, but they are pronounced in the older reproductive ages. They estimate that twice the proportion of black women relative to white are hypertensive during pregnancy. Their results suggest that differential rates of hypertension between black and white women may contribute to the persistent excess infant mortality among blacks, but conclusive results cannot be determined from these data. These data are also valuable for the design and evaluation of screening, intervention, and followup programs for hypertensive disease among young women. PMID:1908590

    The present study aimed to (a) characterize the personal competencies, the social resources, and the psychosocial adjustment (psychological distress, quality of life, and parenting self-perceptions) during the early postpartum period of primiparous women of advanced age (≥35 years at the time of delivery) and their partners (older parents) compared with that of younger first-time mothers (20-34 years) and their partners (younger parents); and (b) explore the role of personal competencies and social resources in couples' psychosocial adjustment, depending on the age group. Older (n = 74) and younger parents (n = 71) completed self-report measures to assess personal competencies and social resources (third trimester of pregnancy), psychological distress, and quality of life (third trimester of pregnancy and 1-month' postpartum) and parenting self-perceptions (1-month' postpartum). Older parents were more similar than different from younger parents regarding personal competencies, social resources, and psychosocial adjustment during the first postnatal month. Regardless of the age group, higher personal competencies and social resources predicted lower anxiety and more positive parenting self-perceptions in women. Beyond higher personal competencies, older maternal age also predicted higher quality of life. In men, higher personal competencies were protective against anxiety, but only at older maternal age.

  5. Frailty prevalence and slow walking speed in persons age 65 and older: implications for primary care

    PubMed Central

    2013-01-01

    Background Frailty in the elderly increases their vulnerability and leads to a greater risk of adverse events. According to various studies, the prevalence of the frailty syndrome in persons age 65 and over ranges between 3% and 37%, depending on age and sex. Walking speed in itself is considered a simple indicator of health status and of survival in older persons. Detecting frailty in primary care consultations can help improve care of the elderly, and walking speed may be an indicator that could facilitate the early diagnosis of frailty in primary care. The objective of this work was to estimate frailty-syndrome prevalence and walking speed in an urban population aged 65 years and over, and to analyze the relationship between the two indicators from the perspective of early diagnosis of frailty in the primary care setting. Methods Population cohort of persons age 65 and over from two urban neighborhoods in northern Madrid (Spain). Cross-sectional analysis. Bivariate and multivariate analysis with binary logistic regression to study the variables associated with frailty. Different cut-off points between 0.4 and 1.4 m/s were used to study walking speed in this population. The relationship between frailty and walking speed was analyzed using likelihood ratios. Results The study sample comprised 1,327 individuals age 65 and older with mean age 75.41 ± 7.41 years; 53.4% were women. Estimated frailty in the study population was 10.5% [95% CI: 8.9-12.3]. Frailty increased with age (OR = 1.14; 95% CI: 1.10-1.19) and was associated with poor self-rated health (OR = 2.52; 95% CI: 1.43-4.44), number of drugs prescribed (OR = 1.17; 95% CI: 1.08-1.26) and disability (OR = 6.58; 95% CI: 3.92-11.05). Walking speed less than 0.8 m/s was found in 42.6% of cases and in 56.4% of persons age 75 and over. Walking speed greater than 0.9 m/s ruled out frailty in the study sample. Persons age 75 and older with walking speed <0.8 m/s are at particularly high

    OBJECTIVE: To evaluate the prevalence of weight excess in children and adolescents attending public and private schools of Campinas, Southeast Brazil, according to age group. METHODS: Cross-sectional study that enrolled 3,130 students from 2010 to 2012. The weight and the height were measured and the body mass index (BMI) was calculated. The students were classified by BMI Z-score/age curves of the World Health Organization (WHO)-2007 (thinness, normal weight, overweight and obesity) and by age group (7-10, 11-14 and 15-18 years). Multinomial logistic regression analysis was applied to verify variables associated to overweight and obesity. RESULTS: Among the 3,130 students, 53.7% attended public schools and 53.4% were girls. The prevalence of weight excess (overweight or obesity) was higher in private schools (37.3%) than in public ones (32.9%) and among males (37.5%), compared to females (32.7%; p<0.05). The chance of having weight excess in children aged 7-10 years was more than twice of those over 15 years old (OR 2.4; 95%CI 2.0-3.0) and it was 60% higher for the group with 11-14 years old (OR 1.6; 95%CI 1.3-2.0). The chance of being obese was three times higher in 7-10 years old children than in the adolescents with 15-18 years old (OR 4.4; 95%CI 3.3-6.4) and 130% higher than the group with 11-14 years old (OR 2.3; 95%CI 1.6-3.2). CONCLUSIONS: The prevalence of weight excess in Campinas keeps increasing at an alarming rate, especially in the younger age group. PMID:25119751

    Summary Background The prevalence of dementia is of interest worldwide. Contemporary estimates are needed to plan for future care provision, but much evidence is decades old. We aimed to investigate whether the prevalence of dementia had changed in the past two decades by repeating the same approach and diagnostic methods as used in the Medical Research Council Cognitive Function and Ageing Study (MRC CFAS) in three of the original study areas in England. Methods Between 1989 and 1994, MRC CFAS investigators did baseline interviews in populations aged 65 years and older in six geographically defined areas in England and Wales. A two stage process, with screening followed by diagnostic assessment, was used to obtain data for algorithmic diagnoses (geriatric mental state–automated geriatric examination for computer assisted taxonomy), which were then used to estimate dementia prevalence. Data from three of these areas—Cambridgeshire, Newcastle, and Nottingham—were selected for CFAS I. Between 2008 and 2011, new fieldwork was done in the same three areas for the CFAS II study. For both CFAS I and II, each area needed to include 2500 individuals aged 65 years and older to provide power for geographical and generational comparison. Sampling was stratified according to age group (65–74 years vs ≥75 years). CFAS II used identical sampling, approach, and diagnostic methods to CFAS I, except that screening and assessement were combined into one stage. Prevalence estimates were calculated using inverse probability weighting methods to adjust for sampling design and non-response. Full likelihood Bayesian models were used to investigate informative non-response. Findings 7635 people aged 65 years or older were interviewed in CFAS I (9602 approached, 80% response) in Cambridgeshire, Newcastle, and Nottingham, with 1457 being diagnostically assessed. In the same geographical areas, the CFAS II investigators interviewed 7796 individuals (14 242 approached, 242 with

    Purpose/Objectives Describe frailty and associated factors in breast cancer survivors Design Cross-sectional descriptive Setting School of nursing Sample 216 breast cancer survivors (BCS) aged 53–87 not currently participating in exercise Methods Performance tests, clinical measures, and self-reported questionnaires provided baseline data analyzed for this study Main Research Variables Frailty was defined as meeting 3 of the 5 criteria of the Frailty Phenotype: shrinking, exhaustion, low activity, slowness, and weakness. Data were compared to published data from women in the Cardiovascular Health Study (CHS) and Women’s Health and Aging Study (WHAS). Findings 18% of BCS aged 70–79 were frail, compared to 11% of CHS and WHAS women aged 70–79. Frailty was more common at a younger age in BCS and more BCS were frail in all age groups compared to CHS women until approximately age 80 when prevalence of frailty was similar in the two groups. 50% of BCS were classified as prefrail because they met 1–2 of the 5 frailty criteria. Higher body mass index increased the odds of frailty and higher physical activity decreased the odds of frailty (OR= 1.12, p=.003 and OR=.99, p=.000 respectively). Conclusions Frailty and prefrailty may be common in BCS and may occur at an earlier age than in adults without a history of cancer. PMID:23615146

    This study sought to determine the prevalence and impact of pain in a nationally representative sample of older adults in the United States. Data from the 2011 National Health and Aging Trends Study were analyzed. In-person interviews were conducted in 7601 adults ages ≥65 years. The response rate was 71.0% and all analyses were weighted to account for the sampling design. The overall prevalence of bothersome pain in the last month was 52.9%, afflicting 18.7 million older adults in the United States. Pain did not vary across age groups (P = 0.21), and this pattern remained unchanged when accounting for cognitive performance, dementia, proxy responses, and residential care living status. Pain prevalence was higher in women and in older adults with obesity, musculoskeletal conditions, and depressive symptoms (P < 0.001). The majority (74.9%) of older adults with pain endorsed multiple sites of pain. Several measures of physical capacity, including grip strength and lower-extremity physical performance, were associated with pain and multisite pain. For example, self-reported inability to walk 3 blocks was 72% higher in participants with than without pain (adjusted prevalence ratio 1.72 [95% confidence interval 1.56-1.90]). Participants with 1, 2, 3, and ≥4 sites of pain had gait speeds that were 0.01, 0.03, 0.05, and 0.08 meters per second slower, respectively, than older adults without pain, adjusting for disease burden and other potential confounders (P < 0.001). In summary, bothersome pain in the last month was reported by half of the older adult population of the United States in 2011 and was strongly associated with decreased physical function.

    The severity of dental mottling in 2,592 school-aged, lifetime residents of 16 Texas communities was investigated in 1980-81 to identify factors associated with mottling and to construct a prediction model for the prevalence of mottling. The communities were selected to obtain a wide range of levels of fluoride in the drinking water. The children within each of the communities were contacted through their schools and received a dental examination to assess the severity of mottling. Information on demographic, dental health practice, and other candidate predictor variables was obtained from a questionnaire completed by a parent. A number of water quality measurements were also recorded for each community. White and Spanish-surname children had about the same prevalence of mottling while Blacks had a higher prevalence, odds ratio (OR) = 2.3, 95% confidence interval = 1.4, 3.7. Children from homes which had air conditioning had a lower prevalence of mottling (OR = .6, (0.4, 0.8)). The use of fluoride toothpaste or drops and the number of fluoride treatments were almost identical among those who did and did not develop moderate mottling. In addition to fluoride, total dissolved solids and zinc were water quality variables associated with mottling. PMID:4061713

    Age-related changes in the average worm burden and the prevalence of Trichuris trichiura infection, in a village community in St. Lucia, were examined by field studies based on worm expulsion techniques. Horizontal age-intensity profiles were convex in form with peak parasite loads occurring in the 2 to 15-year-old children. Prevalence is shown to be a poor indicator of changes in average worm load with age. Faecal egg counts (epg and epd) provide a qualitative measure of worm burdens since fecundity is shown to be approximately independent of worm load. The parasites were highly aggregated within the study community, with most people harbouring low burdens while a few individuals harboured very heavy burdens. Of the total parasite populations in the study sample, 84% were harboured by the 2 to 15-year-old children. Of those individuals harbouring 100 worms or more, 87% were in the 2 to 10-year-old age range. Crude estimates of population parameters (basic reproductive rate, 4-5; rate of reinfection, 90 year-1) suggest that the rate of reinfection is higher than for other helminth parasites of man. The control of morbidity and parasite transmission is discussed in the context of targeting drug treatment at the child segment of the study population.

    The study examined growth in effortful control (executive control, delay ability) in relation to income, cumulative risk (aggregate of demographic and psychosocial risk factors), and adjustment in 306 preschool-age children (50% girls, 50% boys) from families representing a range of income (29% at- or near-poverty; 28% lower-income; 25% middle-income; 18% upper-income), with 4 assessments starting at 36–40 mos. Income was directly related to levels of executive control and delay ability. Cumulative risk accounted for the effects of income on delay ability but not executive control. Higher initial executive control and slope of executive control and delay ability predicted academic readiness, whereas levels, but not growth, of executive control and delay ability predicted social competence and adjustment problems. Low income is a marker for lower effortful control, which demonstrates additive or mediating effects in the relation of income to children’s preschool adjustment. PMID:25253079

    This study examined the associations between symptoms of attention-deficit/hyperactivity disorder (ADHD) and social and school adjustment (academic performance, peer relationships, school social problems) and the moderating roles of children's age and maternal parenting (affection and overprotection) in these associations. The sample consisted of 2,463 students who were in the first to ninth grade in northern Taiwan. Results from the linear mixed models demonstrated that ADHD symptoms were inversely associated with academic performance and positively associated with social adjustment problems. Further, children's age and maternal parenting moderated the associations between ADHD symptoms and school and social adjustment. For example, maternal overprotection moderated the relation between hyperactivity and negative peer relationships (i.e., difficulty forming and maintaining friendships), such that this relation was stronger for children who experienced higher levels of overprotection than children who did not. Moreover, children's age moderated the association between attention problems and decreased academic performance, such that this association was stronger for older children and adolescents than for younger children. Furthermore, children's age and maternal affection interacted to influence the association between attention problems and school social problems (i.e., bullying, aggression, and peer rejection) with maternal affection acting as a buffer for older children (grades 4-6) only. These findings are discussed from a developmental psychopathology perspective.

    Background. Regular walking is critical to maintaining health in older age. We examined influences of individual and community factors on walking habits in older adults. Methods. We analyzed walking habits among participants of a prospective cohort study of 745 community-dwelling men and women, mainly aged 70 years or older. We estimated community variations in utilitarian and recreational walking, and examined whether the variations were attributable to community differences in individual and environmental factors. Results. Prevalence of recreational walking was relatively uniform while prevalence of utilitarian walking varied across the 16 communities in the study area. Both types of walking were associated with individual health and physical abilities. However, utilitarian walking was also strongly associated with several measures of neighborhood socioeconomic status and access to amenities while recreational walking was not. Conclusions. Utilitarian walking is strongly influenced by neighborhood environment, but intrinsic factors may be more important for recreational walking. Communities with the highest overall walking prevalence were those with the most utilitarian walkers. Public health promotion of regular walking should take this into account. PMID:26339507

    Introduction The prevalence of waterpipe tobacco smoking is increasing globally and is associated with adverse outcomes requiring tobacco control interventions. We estimated the prevalence of waterpipe tobacco use among adult populations in Vietnam in 2010 and examined its association with sociodemographic factors. Methods We used data from the Global Adult Tobacco Survey (GATS) conducted in Vietnam in 2010. GATS surveyed a national representative sample of adults aged 15 years or older from 11,142 households by using a 2-phase sampling design analogous to a 3-stage stratified cluster sampling. Descriptive statistical analyses and multivariate logistic regression modeling were conducted. Results A total of 6.4% of Vietnamese aged 15 years or older (representing about 4.1 million adult waterpipe smokers) reported current waterpipe tobacco smoking. The prevalence of waterpipe tobacco smoking was significantly higher among men than women (13% vs 0.1%). Area of residence (rural or urban), age group, asset-based wealth quintile, and geographic region of residence were significantly associated with waterpipe tobacco smoking among men. The significant correlates of current waterpipe tobacco smoking among men were lower education levels, being middle-aged (45–54 years), lower asset-based wealth levels, living in rural areas, not living in the South East and the Mekong River Delta geographic regions, and the belief that smoking does not causes diseases. Conclusion Rural dwellers who are poor should be targeted in tobacco control programs. Further studies are needed that examine perceptions of the adverse health effects and the cultural factors of waterpipe tobacco smoking. PMID:23597395

    The objectives of the study were to describe the prevalence, odds, and predictors of 36 paediatric sleep behaviours and describe their coexistence in a school-age normal population. The design was community-based questionnaire survey of sleep-wake patterns, sleep environment, and 36 sleep behaviours indicative of six sleep disorder-subscales using the Health-Behaviour Questionnaire. A caregivers' report of 3045 children aged 6-13 years in Belgium constituted the participants. Prevalence of each sleep behaviour was calculated. Log-linear modelling within and between the sleep disorder-subscales was used to screen for coexistence. The effect size of selected night-time parameters to the likelihood of sleep behaviours and disorder-subscale was expressed as odds ratios via logit regression analysis. Significant differences in sleep-wake patterns were found between weekday and weekend. Ranking by odds showed that: (1) sleep problems such as 'tired when waking up', 'repetitive limb movements', 'going to bed reluctantly', and 'sleep paralysis' and; (2) the disorder-subscale 'excessive somnolence' are common in children. Coexistences within and between disorder-subscales of sleep problems are evident in a school-age, normal population. These results suggest that disorders of excessive somnolence (DES) are highly prevalent in a non-clinical sample of school-age children. Furthermore, sleep-onset latency and a noisy, not well-darkened room are predictive towards the odds for exhibiting sleep problems and disorders. It is advocated that more information on the importance of good sleep-wake hygiene should reach parents and children.

    Objective: The aim of this study was to present data as responded by parents on teething manifestation during eruption of primary teeth and the occurrence of objective manifestations in children ages 4 months to 36 months. Settings and Design: Hospital based face-to-face questionnaire study. Study Design: One thousand and one hundred children ages four to 36 months who had at least one erupting tooth were included in the study. Parents were asked to complete a short questionnaire and children were then checked by one of the authors. Statistical analysis used: Chi-square analysis was performed to analyze information obtained. Level of significance was set at P<.05. Results: There were 660 girls (60%) and 440 boys (40%) in the study. The most frequent clinical manifestations were: Fever (16%), drooling (12%), diarrhea (8%), fever-drooling (15%), fever-diarrhea(8%) and drooling-diarrhea (6%). In the study sample, boys demonstrated a higher prevalence of diarrhea than girls (P<.05). No statistical significance regarding other clinical manifestations and gender were observed. Teething manifestations were most prevalent during the eruption of primary incisors. Occurrence of clinical manifestations in 4-12months and 13-24 months age was statistically significant when compared with 25-36months age (P<0.05). Conclusions: An association has been shown between general objective manifestations like fever (the most prevalent), drooling and diarrhea, and the eruption of primary teeth. Most manifestations appeared during the eruption of the primary incisors. Key words:Teething, primary teeth, eruption. PMID:22143712

    Each year, an increasing number of children are born through surrogacy and thus lack a genetic and/or gestational link with their mother. This study examined the impact of surrogacy on mother-child relationships and children's psychological adjustment. Assessments of maternal positivity, maternal negativity, mother-child interaction, and child adjustment were administered to 32 surrogacy, 32 egg donation, and 54 natural conception families with a 7-year-old child. No differences were found for maternal negativity, maternal positivity, or child adjustment, although the surrogacy and egg donation families showed less positive mother-child interaction than the natural conception families. The findings suggest that both surrogacy and egg donation families function well in the early school years.

    This study examined the associations between children's and adolescents' autistic-like social deficits and school and social adjustment as well as the moderating roles of age and gender in these associations. The sample consisted of 1321 students (48.7% boys) in Grade 1 to Grade 8 from northern Taiwan. Children's and adolescents' autistic-like social deficits were assessed using the Social Responsiveness Scale (SRS), and their school and social adjustment (i.e., academic performance, negative attitudes toward schoolwork/teachers/classmates, behavioral problems at schools, negative peer relationships, and problems with peers) were assessed using the Social Adjustment Inventory for Children and Adolescents (SAICA). Both measures were completed by the mothers of the participants. Results from the linear mixed models demonstrated that autistic-like social deficits were associated with poor academic performance, negative attitudes toward schoolwork, teachers, and classmates, behavioral problems at schools, negative peer relationships, and problematic peer interactions. Moreover, gender and/or age moderated the associations between autistic-like social deficits and school and social adjustment problems. For example, autistic-like social deficits were more strongly related to negative school attitude, school social problems, and negative peer relationships in boys than in girls. Further, autistic-like social deficits were more strongly related to problems with peers in older girls than in older boys or younger children (regardless of gender). In conclusion, the present study suggests that autistic-like social deficits may place children and adolescents at increased risk for social and school maladjustment and that the extent of maladjustment may vary with the child's age and gender and the domains of adjustment under discussion.

    Physical activity in adolescence is associated with several health benefits, including a direct influence on adolescent morbidity and an indirect effect on adult health mediated by physical activity levels in adulthood. This study assessed the prevalence of sedentary lifestyle and associated variables in 4,452 adolescents aged 10-12 years, belonging to the 1993 Pelotas Birth Cohort Study, representing 87.5% of the original cohort. Sedentary lifestyle, defined as < 300 minutes per week of physical activity, was reported by 58.2% (95%CI: 56.7-59.7) of the cohort. In the multivariate analysis, sedentary lifestyle was positively associated with female gender, socioeconomic status, maternal physical inactivity, and television viewing, but inversely correlated with time spent playing videogames. Adolescents with low socioeconomic status were more likely to walk or bicycle to and from school. Effective strategies against sedentary lifestyle in adolescence are needed because of its high prevalence and association with physical inactivity in adulthood.

    Nearly half of women of reproductive age (WRA) in Cambodia are anemic. To guide interventions, national data on nutritional causes of anemia, including iron deficiency and vitamin A deficiency, are needed. In 2012, a national household survey in WRA on antibodies to routine vaccine-preventable disease immunity was performed. We used serum samples from this survey to estimate the prevalence of iron and vitamin A deficiency in 2112 Cambodian WRA, aged 15 to 39 years. Iron deficiency was classified as low or marginal iron stores (ferritin concentrations corrected for inflammation <15 μg/L and <50 μg/L respectively; Fer), iron deficient erythropoiesis (soluble transferrin receptor concentrations >8.3 mg/L; sTfR), or low total body iron (TBI) derived from Fer and sTfR concentrations (<0 mg/kg). Vitamin A status was classified using retinol binding protein (RBP) concentrations corrected for inflammation as deficient (<0.70 μmol/L) or marginal (<1.05 μmol/L. Overall, the prevalence of low iron stores, low TBI and iron deficient erythropoiesis was 8.1%, 5.0% and 9.3% respectively. Almost 40% of the women had marginal iron stores. Iron status was better in women living in urban areas compared to rural areas (p < 0.05 for TBI and sTfR). The prevalence of vitamin A deficiency was <1%. These findings suggest that the contribution of iron and vitamin A deficiency to the high prevalence of anemia in Cambodian WRA may be limited. The etiology of anemia in Cambodia needs to be elucidated further to guide current policies on anemia. PMID:27043624

    Introduction There are no studies assessing the simultaneous occurrence of Candida albicans (C. albicans) and Trichomonas vaginalis (T. vaginalis) in the primary health care in Brazil. Despite different conditions to establishment of each one, the co-detection of both has been reported by some authors in previous studies from other regions. Aim To compare the prevalence of T. vaginalis and C. albicans in correlation with associated variables. Materials and Methods A cross-sectional study conducted in a family health clinic in the Federal District of Brazil, between November 2014 and March 2015. Vaginal swabs were collected from 201 women of the reproductive age selected from women registered at the family health clinic. Minors and pregnant women were excluded. The rates of T. vaginalis and Candida albicans prevalence were evaluated with vaginal pH, the whiff test, sexual practices and other social and demographic variables. Difference between proportions was assessed by Z-Test. Results C. albicans was present in 20% of the women, while 16% of them had T. vaginalis. The simultaneous occurrence of the agents was found in 1.5%. Significant differences were found between prevalence rates for the variables race/skin colour, practice of anilingus and lifetime number of sexual partners. Conclusion The prevalence of T. vaginalis exceeds C.albicans among women with higher numbers of sexual partners. The prevalence of C. albicans was higher than T. vaginalis among white women and those who practice active and receptive anilingus. The simultaneous occurrence of the two microorganisms was uncommon.

    Standard linear adjustment of weaning weight to a constant age has been shown to introduce bias in the adjusted weight due to nonlinear growth from birth to weaning of beef calves. Ten years of field records from the five strains of Beefbooster Cattle Alberta Ltd. seed stock herds were used to investigate the use of correction factors to adjust standard 180-d weight (WT180) for this bias. Statistical analyses were performed within strain and followed three steps: 1) the full data set was split into an estimation set (ES) and a validation set (VS), 2) WT180 from the ES was used to develop estimates of correction factors using a model including herd (H), year (YR), age of dam (DA), sex of calf (S), all two and three-way interactions, and any significant linear and quadratic covariates of calf age at weaning deviated from 180 d (DEVCA) and interactions between DEVCA and DA, S or DA x S, and 3) significant DEVCA coefficients were used to correct WT180 from the VS, then WT180 and the corrected weight (WTCOR) from the VS were analyzed with the same model as in Step 2 and significance of DEVCA terms were compared. Two types of data splitting were used. Adjusted R2 was calculated to describe the proportion of total variation of DEVCA terms explained for WT180 from the ES. The DEVCA terms explained .08 to 1.54% of the total variation for the five strains. Linear and quadratic correction factors were both positive and negative. Bias in WT180 from the ES within 180 +/- 35 d of age ranged from 2.8 to 21.7 kg.(ABSTRACT TRUNCATED AT 250 WORDS)

  7. Age adjustment in ecological studies: using a study on arsenic ingestion and bladder cancer as an example

    PubMed Central

    2011-01-01

    Background Despite its limitations, ecological study design is widely applied in epidemiology. In most cases, adjustment for age is necessary, but different methods may lead to different conclusions. To compare three methods of age adjustment, a study on the associations between arsenic in drinking water and incidence of bladder cancer in 243 townships in Taiwan was used as an example. Methods A total of 3068 cases of bladder cancer, including 2276 men and 792 women, were identified during a ten-year study period in the study townships. Three methods were applied to analyze the same data set on the ten-year study period. The first (Direct Method) applied direct standardization to obtain standardized incidence rate and then used it as the dependent variable in the regression analysis. The second (Indirect Method) applied indirect standardization to obtain standardized incidence ratio and then used it as the dependent variable in the regression analysis instead. The third (Variable Method) used proportions of residents in different age groups as a part of the independent variables in the multiple regression models. Results All three methods showed a statistically significant positive association between arsenic exposure above 0.64 mg/L and incidence of bladder cancer in men and women, but different results were observed for the other exposure categories. In addition, the risk estimates obtained by different methods for the same exposure category were all different. Conclusions Using an empirical example, the current study confirmed the argument made by other researchers previously that whereas the three different methods of age adjustment may lead to different conclusions, only the third approach can obtain unbiased estimates of the risks. The third method can also generate estimates of the risk associated with each age group, but the other two are unable to evaluate the effects of age directly. PMID:22014275

    Cardiovascular disease (CVD) is a major cause of mortality in type 1 diabetes mellitus (T1D). However, evidence of its risks and management is often extrapolated from studies in type 2 diabetic (T2D) patients or the general population. This approach is unsatisfactory given that the underlying pathology, demographics and natural history of the disease differ between T1D and T2D. Furthermore, with a rising life expectancy, a greater number of T1D patients are exposed to the cardiovascular (CV) risk factors associated with an ageing population. The aim of this review is to examine the existing literature around CVD in T1D. We pay particular attention to CVD prevalence, how well we manage risk, potential biomarkers, and whether the studies included the older aged patients (defined as aged over 65). We also discuss approaches to the management of CV risk in the older aged. The available data suggest a significant CVD burden in patients with T1D and poor management of CV risk factors. This is underpinned by a poor evidence base for therapeutic management of CV risk specifically for patients with T1D, and in the most relevant population – the older aged patients. We would suggest that important areas remain to be addressed, particularly exploring the risks and benefits of therapeutic approaches to CVD management in the older aged. PMID:26568811

    The apparent prevalence of endoparasite infections across different age groups was calculated from 6555 dogs and 1566 cats that had a fecal examination performed upon presentation to the Veterinary Hospital of the University of Pennsylvania between 1997 and 2007. Based on notations from the medical history indicating prior parasite infections, estimates of recurrence were generated for each common group of parasites, including Trichuris, Giardia, ascarids, hookworms, Cystoisospora, and tapeworms. Endoparasitism was predominantly a disease of younger animals, with peak prevalence observed almost uniformly in dogs under 6 months old, with the exception of Trichuris with its longer pre-patent period, and in cats less than 18 months old. Furthermore, nearly 50% of dogs under 6 months old with a history of parasites, were diagnosed with at least one species of parasite on subsequent fecal examination. The percentage dropped to 18.4% in animals aged 1-4 years, but again increased to 31.5% in animals over 10 years old. There was no reported recurrence of Giardia or Cystoisospora from canine or feline patients older than 1 year. The recurrence of whipworm rose steadily with age, while hookworm and roundworm recurrence peaked in patients 1-4 years old. Findings from the study emphasize the importance of follow up fecal examinations and treatments in patients diagnosed with endoparasites.

    Despite a recent increase in the number of adults who work past traditional retirement age, existing theories of vocational behavior have not yet received adequate empirical support. In a large sample of adults age 60-87, we evaluated the relationship between theorized predictors of work satisfaction proposed by Social Cognitive Career Theory (SCCT), work satisfaction as a predictor of continued work, as proposed by the Theory of Work adjustment (TWA), as well as the influence of reported experiences of discrimination on these relationships. While the results supported most of the predicted relationships, the effects of discrimination were stronger than the variables proposed by either SCCT or TWA for the present sample.

    Background: Our information regarding immunity to toxoplasmosis among reproductive age women is indeterminate and there is significant variation between reported results; it is necessary to perform a Meta-analysis study on subjects to obtain required findings and develop preventive measures accordingly. Objective: Estimation level of immunity to toxoplasmosis in reproductive ages. Materials and Methods: All published papers in main national and international databases were systematically searched for some specific keywords to find the related studies up to 2012. We selected only original articles that either reported percentage of positive anti toxoplasma IgG or total anti toxoplasma antibody by using ELISA or IFAT method (provided that the titer ≥1.20 is considered positive for IFAT) in childbearing age women. Results: Studies involved a total of 13480 participants. The maximum and minimum reported prevalence rates of anti-toxoplasma IgG antibody using IFTA serological method were 21.8% and 54%; and using ELISA serological method were 23% and 64%, respectively. The overall estimation for prevalence of anti-toxoplasma IgG antibody using IFTA serological method was 34.5% (95% CI: 28.5-40.5); and using ELISA method was 37.6% (95% CI: 30.4-44.9). The overall estimation for prevalence of anti-toxoplasma total antibody was 39.9% (95% CI: 26.1-53.7). Conclusion: In Iran, screening of toxoplasma is not routinely performed yet, while the incidence of toxoplasmosis is too high to justify routine screening. Prenatal screening can help to identify mothers susceptible to infection. Screening for the presence of antibodies allows primary prevention of toxoplasmosis infection where eating habits and hygiene practices have clearly been identified as risk factors. PMID:24639709

    Hepatitis A Virus (HAV) has been a significant cause of infections among the children and adolescents of Jordan. Availability of safe vaccines made it necessary to identify the ill-defined temporal immunity trends for HAV and possible age-specific prevalence transitions. This community-based cross sectional study was conducted during the period July-August 2008 on 3,066 recruited subjects from the 12 governorates of Jordan, with pre-defined criteria. Several households were chosen at random within each selected block to enroll the subjects. They were interviewed and data were collected. Their sera were tested for total antibodies against HAV. A multivariate model was then performed to identify the possible risk factors. The HAV sero-prevalence rates among the age categories-second year, 2-4 years, 5-9 years, 10-14 years, 15-19 years, and those above 20 years were 26%, 32%, 44%, 63%, 78%, and 94%, respectively. The model revealed the association of several risk factors for higher HAV sero-prevalence rates: (i) older age groups; (ii) lower maternal education levels; (iii) residing in certain governorates; (iv) using public net drinking water; and (v) avoiding use of public net sewage system. This study provided strong evidence for continuous transition of HAV epidemiology towards intermediate endemicity in Jordan, with more susceptible adolescents and adults. Following the World Health Organization (WHO) recommendations for countries with intermediate endemicity, large-scale hepatitis A vaccination is recommended for children in Jordan. This is strengthened by the availability of effective and safe HAV vaccines, improving the socio-economic status of the Jordanians, and increasing life expectancy among Jordanians.

    We assessed the prevalence of microalbuminuria (MAU) and the relationships with other cardiovascular (CV) risk factors among a middle-aged Chinese population. Data from 10 313 participants were included in our cross-sectional survey. Microalbuminuria was defined as the urine albumin to creatinine ratio of 30:300 mg/g from a single-spot morning urine sample. Microalbuminuria was found to be common in males and females (15.04% vs 10.09%) aged 35 to 64 years in this Chinese general population, especially in those with obesity, hypertension, and diabetes. Multivariate analysis found that body mass index, triglyceride, high-sensitivity C-reactive protein, alcohol consumption, hypertension, and diabetes were independently associated with MAU. Microalbuminuria may be a useful indicator for risk of CV disease in general populations.

    The Middle Eastern population is aging rapidly, and as aging is the main risk factor for cancer, the incidence and prevalence of that disease are increasing among all the populations in the region. These developments represent huge challenges to national and community-based health services. At the current state of affairs, most Middle Eastern countries require the cooperation of international agencies in order to cope with such new challenges to their health systems. The focus and emphasis in facing these changing circumstances lie in the education and training of professionals, mainly physicians and nurses, at the primary, secondary and tertiary levels of health services. It is imperative that these training initiatives include clinical practice, with priority given to the creation of multidisciplinary teams both at the cancer centers and for home-based services.

    BACKGROUND. Despite much effort spent on antismoking programs in schools in different countries, limited effects have been observed in many cases. Evidence from European countries shows that active tobacco control actions such as ban on tobacco advertising, increase of tobacco taxes could lead to successful results. Our study was aimed to analyze time trends on smoking in Lithuanian school-aged children during the period of 1994-2006 in the context of antismoking policies, which were implemented in Lithuania. MATERIAL AND METHODS. This study was a part of WHO Cross-National Health Behavior in School-Aged Children (HBSC) study carried out in Lithuania. The standardized methods of international HBSC study protocol were applied. Stratified random representative samples of 5428, 4513, 5645, and 5632 students aged 11, 13, and 15 years were included into school-based anonymous questionnaire surveys in 1994, 1998, 2002, and 2006, respectively (spring semester). Questions on frequency of smoking, age of initiation and other questions were included. Response rates of each of these four questionnaire surveys were higher than 90%. RESULTS. Smoking behavior was more common among boys. The prevalence gap in smoking between boys and girls diminished during period of observation. Prevalence of smoking increased significantly among boys during the period of 1994-2002 (11.3%, 19.8%, and 23.6% in 1994, 1998, and 2002, respectively), but started to decline after (17.3% in 2006, P<0.05). Similar trends were observed among girls: 3.6%, 8.5%, 14.6%, and 12.5% of girls reported smoking in cross-sectional surveys of 1994, 1998, 2002, and 2006, respectively. Boys living in rural areas were more frequent smokers than those living in urban areas in 1994-1998 (9.5% vs 13.9%, P<0.05). However, the surveys of 2002-2006 showed opposite changes (25.6% vs 22.1%, P<0.05 and 17.8% vs 16.9%, P>0.05). Urban girls have reported smoking more frequently in comparison with rural girls.

    The original validation study for the Montreal Cognitive Assessment (MoCA) suggests a cutoff score of 26; however, this may be too stringent for older adults, particularly for those with less education. Given the rapidly increasing number of older adults and associated risk of dementia, this study aims to provide appropriate age- and education-adjusted norms for the MoCA. Data from 205 participants in an ongoing longevity study were used to derive normative data. Individuals were grouped based on age (70-79, 80-89, 90-99) and education level (≤12 Years, 13-15, ≥16 Years). There were significant differences between age and education groups with younger and more educated participants outperforming their counterparts. Forty-six percent of our sample scored below the suggested cutoff of 26. These normative data may provide a more accurate representation of MoCA performance in older adults for specific age and education stratifications.

    This study aimed to assess the prevalence of diabetes and unrecognized diabetes in hypertensive patients aged 40 to 79 years in Southwest China. From September 2013 to March 2014, a cross-sectional survey was conducted in 4021 hypertensive patients aged 40 to 79 years living in Chengdu and Chongqing, China. Fasting plasma glucose (FPG) and 2h plasma glucose (2-hPG) in an oral glucose-tolerance test (OGTT) were used for assessments. Whether the patients previously had diabetes (DM) was determined by their own reports. The survey was carried out by the same questionnaire for all respondents. DM prevalence was 32.0% in hypertensive patients aged 40 to 79 years in Southwest China, with the rates of 29.6% and 33.5% in men and women, respectively (P<0.001). DM prevalence increased with age age and body-mass index. DM prevalence rates were 16.9%, 24.7%, 38.2% and 41.9% in hypertensive patients aged 40–49, 50–59, 60–69 and over 70, respectively. DM prevalence were 30.6%, 27.9%, 37.1%, and 37.4%, for BMI<18.5, 18.5–24.9, 25.0–29.9, and ≥30, respectively. Prevalence of unrecognized DM were 20.8% in hypertensive patients aged 40 to 79 years in Southwest China. Using only fasting blood glucose testing without OGTT would have resulted in 65.0% of missed DM diagnosis in these newly diagnosed patients. The prevalence of DM and unrecognized DM were high in hypertensive patients aged 40 to 79 years in Southwest China.These findings indicate that hypertensive patients aged 40 to 79 years should regularly submit to community-based OGTT screening for timely DM diagnosis.

    Background Intellectual disability (ID), characterized by impairments in intellectual function and adaptive behavior, affects 1-3% of the population. Many studies investigated its etiology, but few are cohort studies in middle-income countries. Aims To estimate prevalence, etiology, and factors related to ID among children prospectively followed since birth in a Southern Brazilian city (Pelotas). Methods In 2004, maternity hospitals were visited daily and births were identified. Live-born infants (n = 4,231) whose family lived in the urban area have been followed for several years. At the age of 2 and 4 years, performances in development and intelligence tests were evaluated using the Battelle Developmental Inventory and Wechsler Intelligence Scale, respectively. Children considered as having developmental delay were invited to attend a genetic evaluation. Results At 4 years of age, the prevalence of ID was 4.5%, and the etiology was classified into 5 groups: environmental (44.4%), genetic (20.5%), idiopathic (12.6%), neonatal sequelae (13.2%), other diseases (9.3%). Most children presented impairment in two or more areas of adaptive behavior. There was no difference in prenatal care attendance or maternal schooling among the groups. Conclusion For about 40% of children, ID was attributed to nonbiological factors, suggesting that the rate may be reduced with appropriate interventions early in life. PMID:27595410

    This study explored the prevalence of filicide-suicide ideation among Taiwanese parents with school-aged children. Multiple risk factors associated with filicide-suicide ideation were assessed, and the potential effect of traditional family values was evaluated. A random sample of 1,564 parents was recruited from 21 elementary schools in a rural area of Taiwan. Potential risk factors, including demographics, family finance, psychological maladjustment, family interaction, and cultural beliefs, were further examined using a hierarchical logistic regression. Overall, 14.6% of the respondents reported having filicide-suicide ideation during the past year. The hierarchical logistic regression analysis showed that demographic factors including age, gender, and ethnicity had no significant effect. Family finances, depression, and conflict with the respondent's spouse were positively associated with filicide-suicide ideation. Finally, the parents' beliefs in traditional family values had a positive effect on filicide-suicide ideation. In other words, filicide-suicide thoughts were more common among those who upheld a strong parental responsibility for care giving and family solidarity. This study revealed a substantial prevalence of filicide-suicide ideation among local parents and identified a number of risk factors associated with those thoughts, namely family financial status, parental depression, and conflict with one's spouse. More importantly, the results highlighted the effect of traditional family values in the process. The potential intention of filicide-suicide as mercy killing and its cultural relevance were discussed.

    The prevalence of anti-HEV isotype-specific antibodies and viraemia were investigated in serum samples collected from slaughter-age pigs (aged 22-24 weeks) from 23 farms in Scotland. Of 176 serum samples tested, 29·0% (n = 51) were anti-HEV IgG positive, 36·9% (n = 65) anti-HEV IgA positive and 29·0% (n = 51) anti-HEV IgM positive. Overall seroprevalence (anti-HEV IgG+ and/or IgA+ and/or IgM+) was 61·4% (n = 108). HEV RNA was detected in 72/162 serum samples (44·4%). Partial sequence of ORF2 (98 nt) was obtained from eight HEV RNA-positive samples and phylogenetic analysis confirmed that they were all of genotype 3. This is the first report on the prevalence of HEV in pigs in Scotland. Given the increasing incidence of locally acquired HEV infection in the UK, evidence that HEV is a foodborne zoonosis emphasizes the need for surveillance in pigs.

    Anaemia is a major public health problem in India. Although nearly three quarters of the Indian population live in rural areas, the epidemiology of anaemia in rural settings is not well known. We performed a retrospective observational study using routine clinical data from patients attending the out-patient clinics of a rural hospital in India from June 2011 to August 2014. The study included 73,795 determinations of haemoglobin. 49.5% of patients were female. The median haemoglobin concentration was 11.3 g/dL (interquartile range (IQR), 9.8-12.4) in females and 12.5 g/dL (IQR, 10.6-14.2) in males. Anaemia was present in the majority of children <10 years, women after puberty, and older adults. Children <5 years had the highest prevalence of anaemia, especially children aged 1-2 years. The high proportion of microcytic anaemia and the fact that gender differences were only seen after the menarche period in women suggest that iron deficiency was the main cause of anaemia. However, the prevalence of normocytic anaemia increased with age. The results of this study can be used by public health programmes to design target interventions aimed at reducing the huge burden of anaemia in India. Further studies are needed to clarify the aetiology of anaemia among older adults.

    The aim of this study was to evaluate the metabolic syndrome (MetS) prevalence in adolescents using three different definitions for this age group. The evaluated sample consisted of 718 male and 743 female adolescents. Definitions by Cook et al., de Ferranti et al. and International Diabetes Federation (IDF) for adolescents were used to estimate the prevalence of MetS. The prevalence of MetS was 8.5, 2.5 and 1.2% by de Ferranti et al., Cook et al. and IDF definitions, respectively. High fasting glucose component had the lower prevalence whereas high triglycerides levels component was the most prevalent. In obese adolescents, the prevalence of MetS was higher. MetS classification in adolescents strongly depends on the definition chosen. Further research is required for the evaluation of the current definitions (multicentric studies), and for addition or design of new and useful criteria.

    Background: Hepatitis B is a liver infection caused by the hepatitis B virus (HBV). It affects all women and men irrespective of age. Although sub-Saharan Africa is an area of high prevalence of this disease, data on the prevalence of acute and chronic HBV infections in this region remain to be widely documented. Objective: This study aimed to investigate the prevalence of HBV in relation to age in Centre Hospitalier Universitaire Campus (CHU-C), one of the two teaching hospitals of Lome, Togo. Method: The present study is a cross-sectional study about the prevalence of hepatitis B surface antigen (HBsAg) carriage from 2009 to 2011. All study participants were screened for HBsAg at the Immunology laboratory of CHU Campus of Lome. Results: One thousand two hundred individuals were screened for HBsAg from 2009-2011. The overall prevalence of HBV infection was 19.08%. This prevalence was significantly higher in men (25.00%) than women (14.80%). The highest prevalence of HBV was observed in age range of 20-29 years and 30-39 years with respectively 26.33% and 21.67%. The lowest prevalence was 6.08%, found in people over 50 years. Concerning the clinical indication of the test, the prevalence during the clinical abnormalities related to liver (CARL) was the highest (26.21%), followed by the systematic screening (SS) with 20.25% while the pre-operative assessment (POA) showed the lowest prevalence with 5.56%. Conclusion: The study shows the high prevalence of HBsAg carriage in young people. This could be used to enhance prevention and treatment of HBV infection in Togo. PMID:28217218

    Secondhand smoke (SHS) is a major risk factor for poor health outcomes among women in China, where proportionately few women smoke. This is especially the case as it pertains to women's reproductive health, specifically migrant women who are exposed to SHS more than the population at large. There are several factors which may increase migrant women's risk of SHS exposure. This paper aims to investigate the prevalence and associated factors of SHS exposure among internal Chinese migrant women of reproductive age. The data used were derived from the 2014 Chinese Labor Dynamic Survey, a national representative panel survey. The age-adjusted rate of SHS exposure of women of reproductive age with migration experience was of 43.46% (95% CI: 40.73%-46.40%), higher than those without migration experience (35.28% (95% CI: 33.66%-36.97%)). Multivariate analysis showed that participants with a marital status of "Widowed" had statistically lower exposure rates, while those with a status of "Cohabitation" had statistically higher exposure. Those with an undergraduate degree or above had statistically lower SHS exposure. Those with increasing levels of social support, and those who currently smoke or drink alcohol, had statistically higher SHS exposure. Participants' different work-places had an effect on their SHS exposure, with outdoor workers statistically more exposed. Our findings suggest that urgent tobacco control measures should be taken to reduce smoking prevalence and SHS exposure. Specific attention should be paid to protecting migrant women of reproductive age from SHS.

    The older adult population is growing rapidly in the USA and it is expected that by 2040 the number of adults ≥ 65 years of age will have increased by about 50%. With the growth of this subpopulation, oral health status, and periodontal status in particular, becomes important in the quest to maintain an adequate quality of life. Poor oral health can have a major impact, leading to tooth loss, pain and discomfort, and may prevent older adults from chewing food properly, often leading to poor nutrition. Periodontitis is monitored in the USA at the national level as part of the Healthy People 2020 initiative. In this report, we provide estimates of the overall burden of periodontitis among adults ≥ 65 years of age and after stratification according to sociodemographic factors, modifiable risk factors (such as smoking status), the presence of other systemic conditions (such as diabetes) and access to dental care. We also estimated the burden of periodontitis within this age group at the state and local levels. Data from the National Health and Nutrition Examination Survey 2009/2010 and 2011/2012 cycles were analyzed. Periodontal measures from both survey cycles were based on a full-mouth periodontal examination. Nineteen per cent of adults in this subpopulation were edentulous. The mean age was 73 years, 7% were current smokers, 8% lived below the 100% Federal Poverty Level and < 40% had seen a dentist in the past year. Almost two-thirds (62.3%) had one or more sites with ≥ 5 mm of clinical attachment loss and almost half had at least one site with probing pocket depth of ≥ 4 mm. We estimated the lowest prevalence of periodontitis in Utah (62.3%) and New Hampshire (62.6%) and the highest in New Mexico, Hawaii, and the District of Columbia each with a prevalence of higher than 70%. Overall, periodontitis is highly prevalent in this subpopulation, with two-thirds of dentate older adults affected at any geographic level. These findings provide an

    In this study, we examine race, sex, and self-reported arrest histories (excluding arrests for minor traffic violations) from the 1997 National Longitudinal Survey of Youth (NLSY; N = 7,335) for the period 1997 through 2008 covering cumulative arrest histories through ages 18 and 23. The analysis produces three key findings: (1) males have higher cumulative prevalence of arrest than females; and (2) there are important race differences in the probability of arrest for males but not for females. Assuming the missing cases are missing at random, about 30% of black males have experienced at least one arrest by age 18 (vs. about 22% for white males); by age 23 about 49% of black males have been arrested (vs. about 38% for white males). Earlier research using the NLSY showed that the risk of arrest by age 23 was 30%, with nonresponse bounds [25.3%, 41.4%]. This study indicates that the risk of arrest is not evenly distributed across the population. Future research should focus on the identification and management of collateral risks that often accompany arrest experiences. PMID:26023241

    In this study, several factors related to psychological adjustment of school-age children were examined in a sample of 40 lower-class families in which the parents were separated. It was hypothesized that parental conflict and other indices of family adversity, including maternal depression, income, and the length of time past since parental separation, would be important predictors of children's behavioral adjustment. Parental acrimony was found to be a significant correlate of children's behavioral problems, even when other family variables were taken into account. In addition, independent and additive effects on children's functioning were found for parental discord and maternal depression, with some support found for an additional variable, family income. In contrast to some prior investigations, the length of time since parental separation was unrelated to children's functioning. Results are discussed in terms of Rutter's cumulative stress hypothesis and previous research on parental discord.

    Asthma is the most common chronic disease among children, and its incidences are often imminent among elementary schoolchildren. This study aimed to examine the prevalence of asthma symptoms in Golestan schoolchildren aged 6-7 and 13-14 years in Northeast Iran. The prevalence rate was compared according to age group (aged 6-7 years vs. aged 13-14 years) and gender (male vs. female). In this cross-sectional study, 1706 Iranian schoolchildren aged 6-7 and 13-14 years in Golestan Province were enrolled. Participants completed questionnaires between February and July 2014. Asthma symptoms were assessed using the questionnaire of the International Study of Asthma and Allergies in Childhood protocol in Persian. The logistic regression model was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of the asthma symptoms for each of the gender and age groups. The prevalence rates of "current asthma" symptoms and "asthma ever" in all the children were estimated as 9.5% and 7.5%, respectively. The prevalence of asthma ("asthma ever" and "wheezing in the past 12 months") in junior high schoolchildren (aged 13-14 years) is higher than that in elementary schoolchildren (aged 6-7 years) (P < 0.05). The prevalence of the severity of wheezing in girls is lower than that in boys (OR = 1.7, 95%CI = 1.06-2.96, P = 0.02). Asthma is still a major public health problem. This study shows that the prevalence of the asthma symptoms in boys is lower than that in girls in both age groups, and the severity of asthma in girls is higher than that in boys aged 13-14 years.

    Epidemiological studies in high income countries suggested that a big proportion of the population in Europe and America report adverse reactions to food. Self-reported prevalence of food allergy varied from 1.2% to 17% for milk, 0.2% to 7% for egg, 0% to 2% for peanuts and fish, 0% to 10% for shellfish, and 3% to 35% for any food. The aim of our study was to report the prevalence of self-reported food allergy in the different age groups of Georgian population and to reveal the most common self-reported food allergens. ISAAC phase III study methodology and questionnaires were used for data collection. Questions about food allergy were added to the survey and involved questions about self-reported food allergy. 6-7 years old 6140 children (response rate-94,5%) and 13-14 years old 5373 adolescents (response rate-86,9%) from two locations of Georgia, Tbilisi and Kutaisi were surveyed. 500 randomly assessed adults from Tbilisi aged 18 years and older were added later (response rate-97,6%). Findings revealed that self-reported food allergy among 6-7 years old age group and 13-14 years old age were almost the same (15,7% and 15,9% correspondingly) and slightly lower in adult population - 13,9%. Study revealed, that hen's egg was the commonest implicated food for 6-7 years age group, hazel nut - for 13-14 years old age group followed by hen's egg. Walnut and hazel nut were most reported foods for adult population. The findings also revealed that food allergy is one of the most important risk factor for symptoms associated with asthma (OR-3,05; 95%CI 2.50-3.74), rhinoconjunctivitis (OR-2,85; 95%CI 2.24-3.64) and eczema (OR-5,42; 95%CI 4.08-7.18) in childhood. The data has provided the first epidemiological information related to food allergy among children and adults in Georgia. Results should serve as baseline information for food allergy screening, diagnosis and treatment. Our findings can also inform the public health officials on the disease burden and may offer some

    Purpose. To describe the prevalence of corneal astigmatism in infants and young children who are members of a Native American tribe with a high prevalence of refractive astigmatism. Methods. The prevalence of corneal astigmatism was assessed by obtaining infant keratometer (IK4) measurements from 1235 Tohono O'odham children, aged 6 months to 8 years. Results. The prevalence of corneal astigmatism >2.00 D was lower in the 1- to <2-year-old age group when compared with all other age groups, except the 6- to <7-year-old group. The magnitude of mean corneal astigmatism was significantly lower in the 1- to <2-year age group than in the 5- to <6-, 6- to <7-, and 7- to <8-year age groups. Corneal astigmatism was with-the-rule (WTR) in 91.4% of astigmatic children (≥1.00 D). Conclusions. The prevalence and mean amount of corneal astigmatism were higher than reported in non–Native American populations. Mean astigmatism increased from 1.43 D in 1-year-olds to nearly 2.00 D by school age. PMID:21460261

    The present study evaluates trends in the prevalence of overweight and obesity in relation to gender and area of residence between two cohorts of students aged 11–13 years in Sicily. The analysis was performed on 1,839 schoolchildren, with 924 and 915 children being studied in 1999–2001 and 2009–2010, respectively. The children who were enrolled during 2009–2010 had significantly higher body mass indexes (BMI), BMI z-scores, and waist circumferences than the children who were studied during 1999–2001 (p<0.0001 for all); these differences was also observed when the cohort was subdivided according to gender or residence area The prevalence of obesity increased significantly from 7.9% in 1999–2001 to 13.7% in 2009–2010 (p<0.0001), whereas thinness decreased significantly from 10.1% to 2.3% (p<0.0001) in the same periods. The increase of trends in the prevalence of obesity was significantly higher in males (9.7% vs. 17.6%, p = 0.0006) than in females (6.3% vs. 9.8%, p = 0.04) and was slightly higher in urban areas (8.8% vs. 14.3%, p = 0.002) than in rural areas (7.8% vs. 13.0%, p = 0.012). The male gender was associated with a higher risk of being overweight or obese (odds ratio: 1.63; 95% confidence intervals: 1.24–2.15; p = 0.0005) in 2009–2010 than in 1999–2001, after adjusting for age and the residence area. In conclusion, this study showed an increasing trend in the prevalence of overweight and obesity in Sicilian schoolchildren during the last decade and that this trend was related to gender, age and the area of residence. More specifically, our data indicated that the prevalence of obesity increased by 5.8%, the prevalence of thinness decreased by 7.8% and the prevalence of normal-weight children did not change over the course of a decade. These results suggest a shift in the body weights of Sicilian children toward the upper percentiles. PMID:22506027

More specifically, our data indicated that the prevalence of obesity increased by 5.8%, the prevalence of thinness decreased by 7.8% and the prevalence of normal-weight children did not change over the course of a decade. These results suggest a shift in the body weights of Sicilian children toward the upper percentiles.

    Congenital cataract (CC) is the primary cause of treatable childhood blindness. Population-based assessments of prevalence and surgery age of CC, which are critical for improving management strategies, have been unavailable in China until now. We conducted a hospital-based, cross-sectional study of the hospital charts of CC patients younger than 18 years old from January 2005 to December 2010 at Zhongshan Ophthalmic Center (ZOC) in Guangzhou, China. Residence, gender, age at surgery, hospitalization time, and the presence of other ocular abnormalities were extracted and statistically analyzed in different subgroups. The search identified 1314 patients diagnosed with CC from a total of 136154 hospitalizations, which accounted for 2.39% of all the cataract in-patients and 1.06% of the total in-patients over the six-year study period. Of the identified CC patients, 9.2% had ≥ 2 hospitalizations due to the necessity of additional surgeries, with a total ratio of boys to girls of 1.75 ∶ 1. Based on a subgroup analysis according to age, patients 2-6 years old constituted the highest proportion (29.22%) of all hospitalized CC patients, and those 13-18 years old constituted the lowest proportion (13.47%) of the total number. The average age at surgery was 27.62 ± 23.36 months, but CC patients ≤ 6 years old (especially ≤ 6 months old) became increasingly prevalent throughout the 6-year study period. A total of 276 cases (20.93%) of CC were associated with one or more other ocular abnormalities, the highest incidence rates were observed for exotropia (6.24%), nystagmus (6.16%), and refractive error (3.65%). In conclusion, CC patients accounted for 2.39% of all cataract in-patients in a review of 6 years of hospitalization charts from ZOC. The age at the time of surgery decreased over the 6-year study period, which probably reflects the continuing improvement of public awareness of children's eye care in China.

    Female sex hormones play an important role in the etiology and pathophysiology of a variety of musculoskeletal degenerative diseases. Postmenopausal women show accelerated disc degeneration due to relative estrogen deficiency. This literature review aims to validate or falsify this hypothesis, i.e., while overall females have higher prevalence of low back pain (LBP) across all age groups, this male vs. female difference in LBP prevalence further increases after female menopause age. The literature search was performed on PubMed on January 2, 2016. The search word combination was (low back pain) AND prevalence AND [(males OR men) AND (females OR women)]. The following criteria were taken to include the papers for synthetic analysis: (I) only English primary literatures on nonspecific pain; (II) only prospective studies on general population, but not population with occupational LBP causes, of both males and female subjects studied using the same LBP criterion, ages-specific information available, and males and female subjects were age-matched; (III) studies without major quality flaws. In total 98 studies with 772,927 subjects were analyzed. According to the information in the literature, participant subjects were divided into four age groups: (I) school age children group: 6–19 years; (II) young and middle aged group: 20–50 years; (III) mixed age group: data from studies did not differentiate age groups; (IV) elderly group: ≥50 years old. When individual studies were not weighted by participant number and each individual study is represented as one entry regardless of their sample size, the median LBP prevalence ratio of female vs. males was 1.310, 1.140, 1.220, and 1.270 respectively for the four age groups. When individual studies were weighted by participant number, the LBP prevalence ratio of female vs. males was 1.360, 1.127, 1.185, and 1.280 respectively for the four groups. The higher LBP prevalence in school age girls than in school age boys is likely

    The present study examined the prevalence of behaviours in dogs separated from the litter for adoption at different ages. Seventy adult dogs separated from their dam and littermates and adopted between the ages of 30 and 40 days were compared with 70 adult dogs that had been taken from the litter for adoption at two months. Owners were asked to complete a questionnaire eliciting information on whether their dog exhibited potentially problematic behaviours when in its usual environment. Binary logistic regression analysis was performed to investigate whether the age at which the dog was separated from the litter might predispose it to developing undesirable behaviours. The odds of displaying destructiveness, excessive barking, fearfulness on walks, reactivity to noises, toy possessiveness, food possessiveness and attention-seeking were significantly greater for the dogs that had been removed from the litter earlier during the socialisation period. In addition, dogs purchased from a pet shop at 30 to 40 days of age were reported to exhibit some of the listed behaviours with a significantly higher frequency than dogs purchased from a pet shop at two months. No significant differences were observed with dogs obtained from other types of sources. The dogs in the youngest age group (18 to 36 months) had a higher probability of displaying destructiveness and tail chasing. These findings indicate that, compared with dogs that remained with their social group for 60 days, dogs that had been separated from the litter earlier were more likely to exhibit potentially problematic behaviours, especially if they came from a pet shop.

    Abstract Objective: to estimate the prevalence and factors associated with preoperative anxiety in children who wait for outpatient surgery. Method: cross-sectional analysis of baseline data of a prospective cohort study that investigates the predictors of postoperative pain in children aged 5-12 years submitted to inguinal and umbilical hernia repair. It was selected 210 children, which were interviewed in the preoperative holding area of a general hospital. Anxiety was evaluated using the modified Yale Preoperative Anxiety Scale (mYPAS). Sociodemographic and clinical variables were analyzed as exposure and anxiety (mYPAS final score>30) as outcome. Logistic regression was used to identify factors associated with preoperative anxiety. Results: forty-two percent (42.0%) of children presented preoperative anxiety (CI95%: 35.7%-48.6%), with mean scores equal to 30.1 (SD=8.4). Factors associated with preoperative anxiety were: age group of 5-6 years (OR=2.28; p=0.007) and socioeconomic status classified as class C (OR=2.39; p=0.016). Conclusion: the evaluation of children who wait for outpatient surgery should be multidimensional and comprise information on age and socioeconomic status, in order to help in the identification and early treatment of preoperative anxiety.

    We investigated the prevalence and correlates of suicidal ideation in an Australian population sample at three stages of adulthood. Random sampling of a community acquired 7485 participants. Cohorts were 20 to 24, 40 to 44, or 60 to 64 years old. Twelve-month prevalence of suicidal ideation was 8.2%. Suicidal ideation was highest among the youngest cohort. Males with chronic physical illness were more prone to suicidal ideation, as were those aged 20 to 24 and 60 to 64. Furthermore, under-employed subjects 60 to 64 years old were seven times more likely to experience suicidal ideation than their counterparts working full-time. Childhood adversity and rumination had positive associations with suicidality; however, considering oneself more masterful was linked with lower levels of suicidal ideation. Contrary to clinical and popular views, our results highlight that proximal non-mental health variables such as employment, physical health, social factors, and personality are equally important to experiencing suicidal ideation as symptoms of psychological distress.

    Twenty two patients over the age of 40 with stable spinal cord damage underwent overnight sleep studies to investigate the prevalence of sleep apnoea. Ten patients had some evidence of obstructive sleep apnoea (OSA). Hypoxic events were scored as number of dips of SaO2 more than 4% below the preceding 10 minute average (> 4% SaO2 dip rate). All the patients had more than five such dips per hour and six had clearly abnormal dip rates of more than 15 per hour. Two other patients had dip rates above 10 per hour without apnoeas but periods of central hypoventilation mainly during rapid eye movement (REM) sleep. OSA appears to be more common in older patients with spinal cord injury than in the general population. Possible relevant factors include patient selection, reduced ventilatory function secondary to spinal cord damage, sleep posture and medication. PMID:1469399

    Despite a recent increase in the number of adults who work past traditional retirement age, existing theories of vocational behavior have not yet received adequate empirical support. In a large sample of adults age 60–87, we evaluated the relationship between theorized predictors of work satisfaction proposed by Social Cognitive Career Theory (SCCT), work satisfaction as a predictor of continued work, as proposed by the Theory of Work adjustment (TWA), as well as the influence of reported experiences of discrimination on these relationships. While the results supported most of the predicted relationships, the effects of discrimination were stronger than the variables proposed by either SCCT or TWA for the present sample. PMID:26101456

    The purposes of this study were to evaluate the growth of the surface damage layer in polymer matrix composites (PMC's) fabricated with graphite fabric reinforcement and to determine the effects of the cut-surface degradation on the overall thermo-oxidative (TOS) stability of these materials. Four important conclusions were made about the TOS behavior of T650-35/PNIR- 15 fabric-reinforced composites: (1) Three stages of composite weight loss were seen on the plot of weight loss versus aging time; (2) the depth of the cut-edge damage is related to the composite thickness; (3) the actual weight loss realized by a mechanical test specimen that has had all the aging-induced cut-edge damage removed during the preparation process is significantly less than the weight loss measured using specimens with a high percentage of cut edges exposed to the damaging environment; and (4) an extrapolation of a section of the weight loss curve can be used to obtain a more correct estimate of the actual weight loss after extended periods of aging at elevated temperatures.

    Importance Tourette syndrome (TS) is characterized by high rates of psychiatric comorbidity; however, few studies have fully characterized these comorbidities. Furthermore, most studies have included relatively few participants (<200), and none has examined the ages of highest risk for each TS-associated comorbidity or their etiologic relationship to TS. Objective To characterize the lifetime prevalence, clinical associations, ages of highest risk, and etiology of psychiatric comorbidity among individuals with TS. Design, Setting, and Participants Cross-sectional structured diagnostic interviews conducted between April 1, 1992, and December 31, 2008, of participants with TS (n = 1374) and TS-unaffected family members (n = 1142). Main Outcomes and Measures Lifetime prevalence of comorbid DSM-IV-TR disorders, their heritabilities, ages of maximal risk, and associations with symptom severity, age at onset, and parental psychiatric history. Results The lifetime prevalence of any psychiatric comorbidity among individuals with TS was 85.7%; 57.7% of the population had 2 or more psychiatric disorders. The mean (SD) number of lifetime comorbid diagnoses was 2.1 (1.6); the mean number was 0.9 (1.3) when obsessive-compulsive disorder (OCD) and attention-deficit/hyperactivity disorder (ADHD) were excluded, and 72.1% of the individuals met the criteria for OCD or ADHD. Other disorders, including mood, anxiety, and disruptive behavior, each occurred in approximately 30% of the participants. The age of greatest risk for the onset of most comorbid psychiatric disorders was between 4 and 10 years, with the exception of eating and substance use disorders, which began in adolescence (interquartile range, 15–19 years for both). Tourette syndrome was associated with increased risk of anxiety (odds ratio [OR], 1.4; 95% CI, 1.0–1.9; P = .04) and decreased risk of substance use disorders (OR, 0.6; 95% CI, 0.3–0.9; P = .02) independent from comorbid OCD and ADHD; however, high rates

    The objective of this study was to determine the prevalence of asthma and use of asthma medications in elite athletes compared with an age-matched non-athlete population. Data were collected from the respiratory component of annual medical screening of 424 elite athletes from the Queensland Academy of Sport. Measures included the prevalence of current asthma and ever doctor-diagnosed asthma, and the prevalence of use of treatment for asthma including beta-agonists and inhaled corticosteroid medication. The prevalence of current asthma in athletes aged 18-29 years was 14% (95% CI, 9-19%), which did not differ significantly from the prevalence in the non-athlete control population (11%; 95% CI, 9-12%, P=0.3). Of athletes with current asthma, 27% were not taking any medications for asthma, and 25% were treated with short-acting beta-agonist medications alone and were not taking inhaled corticosteroids. These data indicate that the overall cumulative and period prevalence of asthma in Queensland athletes is similar to that in the general age-matched population. Athletes use beta-agonists with a frequency similar to the general population.

    Background Pterygium is a common chronic ophthalmic condition, which may result in significant visual morbidity or lead to blindness in extreme cases. The prevalence of pterygium in China has not been reported at the sub-national level. Methods In this study, we conducted a systematic review and meta-analysis to estimate the prevalence of pterygium in China. China National Knowledge Infrastructure (CNKI), Wanfang, Chinese Biomedicine Literature Database (CBM-SinoMed), PubMed, Embase and Medline were searched before September 2016. We performed a multilevel mixed-effect meta-regression based on the included studies, our results showed that age, gender and latitude were significantly associated with pterygium prevalence. Based on the final model, the age and gender-specific prevalence of pterygium in 31 Chinese provinces (except Hongkong, Macau and Taiwan) and the whole country was generated. Results In 2010, the overall prevalence of pterygium in Chinese people aged 15–84 years was 9.84% (95% CI: 6.72–14.14), and the number of pterygium cases in China was 108.65 million (95% CI: 74.23–156.13). Conclusions In conclusion, the prevalence of pterygium in Chinese population in 2010 was estimated at both the national and provincial levels. The higher burden of pterygium across the country calls for efforts to advocate public health education encouraging people to take appropriate protective measures. PMID:28355301

    Background Cyberbullying has established links to physical and mental health problems including depression, suicidality, substance use, and somatic symptoms. Quality reporting of cyberbullying prevalence is essential to guide evidence-based policy and prevention priorities. The purpose of this systematic review was to investigate study quality and reported prevalence among cyberbullying research studies conducted in populations of US adolescents of middle and high school age. Methods Searches of peer-reviewed literature published through June 2015 for “cyberbullying” and related terms were conducted using PubMed, PsycINFO, CINAHL Plus, and Web of Science. Included manuscripts reported cyberbullying prevalence in general populations of U.S. adolescents between the ages of 10 and 19. Using a review tool based on the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement, reviewers independently scored study quality on study methods, results reporting, and reported prevalence. Results Search results yielded 1,447 manuscripts; 81 manuscripts representing 58 unique studies were identified as meeting inclusion criteria. Quality scores ranged between 12 and 37 total points out of a possible 42 points (M = 26.7, SD = 4.6). Prevalence rates of cyberbullying ranged as follows: perpetration, 1% to 41%; victimization, 3% to 72%; and overlapping perpetration and victimization, 2.3% to 16.7%. Conclusions Literature on cyberbullying in US middle and high school aged students is robust in quantity but inconsistent in quality and reported prevalence. Consistent definitions and evidence-based measurement tools are needed. PMID:26576821

    Investigations of hooded seals Cystophora cristata have revealed high prevalences of Brucella-positive seals in the reduced Northeast Atlantic stock, compared to the increasing Northwest Atlantic stock. This study evaluated the relation between Brucella-serostatus in seals in the Northeast Atlantic stock and age, sex, body condition and reproduction. Bacteriology documented which animals and organs were B. pinnipedialis positive. No relationship was observed between Brucella-serostatus and body condition or reproductive traits. Pups (<1 mo old) had a substantially lower probability of being seropositive (4/159, 2.5%) than yearlings (6/17, 35.3%), suggesting that exposure may occur post-weaning, during the first year of life. For seals >1 yr old, the mean probability of being seropositive decreased with age, with no seropositives older than 5 yr, indicating loss of antibody titre with either chronicity or clearance of infection. The latter explanation seems to be most likely as B. pinnipedialis has never been isolated from a hooded seal >18 mo old, which is consistent with findings in this study; B. pinnipedialis was isolated from the retropharyngeal lymph node in 1 seropositive yearling (1/21, 5%). We hypothesize that this serological and bacteriological pattern is due to environmental exposure to B. pinnipedialis early in life, with a subsequent clearance of infection. This raises the question of a reservoir of B. pinnipedialis in the hooded seal food web.

    The aim of the present study was to determine associations of thyroid hormone levels and different metabolic parameters and anthropometric measurements with volume of nodular and nonnodular thyroid as well as with prevalence of goiter and thyroid nodules in middle-aged euthyroid subjects. Methods. The study consisted of 317 euthyroid subjects aged 48-49 from the Kaunas Cardiovascular Risk Cohort study. Thyroid-stimulating hormone (TSH), free thyroxine (FT4), and antithyroid peroxidase antibody (ATPO) levels, as well as anthropometric and metabolic parameters and smoking information, were evaluated. Results. In subjects with and without thyroid nodules, thyroid volume correlated with components of metabolic syndrome, body mass index (BMI), smoking, and TSH levels. In the nonnodular thyroid group, thyroid volume was also positively related to serum insulin and HOMA-IR, whereas a negative correlation between thyroid volume and leptin was identified in the nodular thyroid group. The goiter was identified in 12.3% of subjects. Female gender, thyroid nodules, smoking, BMI, and levels of TSH were independent predictors for goiter. Thyroid nodules were found in 31.2% of participants. Female gender, higher TSH levels, and thyroid volume were independent risk factors for thyroid nodules. Conclusions. Female gender, thyroid nodules, smoking, BMI, and TSH levels were identified as potential predictors of goiter. Female gender, TSH levels, and thyroid volume predicted the presence of thyroid nodules. PMID:28356911

    Thrombophilia is a well-established risk factor for a venous thromboembolic event (VTE), and it has been proposed that hereditary thrombophilia may substantially contribute to the development of VTE in young patients. We aimed to analyse the prevalence of thrombophilia with special regard to the age of VTE manifestation. The study cohort consisted of 1490 patients (58% females) with a median age 43 years at the time of their first VTE. At least one thrombophilic disorder was identified in 50·1% of patients. The probability of detecting a hereditary thrombophilia declined significantly with advancing age (from 49·3% in patients aged 20 years and younger to 21·9% in patients over the age of 70 years; P < 0·001). This may be primarily attributed to the decreasing frequencies of the F5 R506Q (factor V Leiden) mutation and deficiencies of protein C or protein S with older age at the time of the initial VTE event. Moreover, thrombophilia was more prevalent in unprovoked compared with risk-associated VTE (57·7% vs. 47·7%; P = 0·001). The decline in the prevalence of hereditary thrombophilia with older ages supports the use of a selected thrombophilia screening strategy dependent on age and the presence or absence of additional VTE risk factors.

    Objective To identify the prevalence and predictors of malnutrition among 2-year old children in the Western Highlands of Guatemala. Methods Prospective cohort of 852 Guatemalan children in San Lucas Toliman, Guatemala followed from birth to age 2 from May 2008 to December 2013. Socio-demographic, anthropometric, and health data of children was collected at 2 month intervals. Results Among the 402 males and 450 females in the cohort, mean weight-for-age Z-score (WAZ) declined from -0.67 ± 1.01 at 1 year to -1.07 ± 0.87 at 2 years, while mean height-for-age Z-score (HAZ) declined from -1.88 ± 1.19 at 1 year to -2.37 ± 0.99 at 2 years. Using multiple linear regression modeling, number of children <5 years old, vomiting in the past week, fever in the past week, and WAZ at 1 year were significant predictors of WAZ at 2 years. Significant predictors of HAZ at 2 years included household size, number of children <5 years old, diarrhea in the past week, WAZ at 1 year, and HAZ at 1 year. Vomiting in the past week and WAZ at 1 year were significant predictors of weight-for-height z-score (WHZ) at 2 years. Conclusions Number of children <5 years old, symptoms such as vomiting or diarrhea in the previous week, and prior nutritional status were the most significant predictors of malnutrition in this cohort. Future research may focus on the application of models to develop predictive algorithms for mobile device technology, as well as the identification of other predictors of malnutrition that are not well characterized such as the interaction of environmental exposures with protein consumption and epigenetics.

    Objective. To determine the prevalence and risk factors for anemia in child bearing age women in Riyadh, Saudi Arabia. Design. Cross-sectional survey was conducted using two-stage cluster sampling. 25 clusters (primary health care centers (PHCC)) were identified from all over Riyadh, and 45–50 households were randomly selected from each cluster. Eligible women were invited to PHCC for questionnaire filling, anthropometric measurements, and complete blood count. Blood hemoglobin was measured with Coulter Cellular Analysis System using light scatter method. Setting. PHCC. Subjects. 969 (68%) women out of 1429 women were included in the analysis. Results. Mean hemoglobin was 12.35 (±1.80) g/dL, 95% CI 12.24–12.46 with interquartile range of 1.9. Anemia (Hb <12 g/dL) was present in 40% (390) women. Mean (±SD) for MCH, MCV, MCHC, and RDW was 79.21 (±12.17) fL, 26.37 (±6.21) pg, 32.36 (±4.91) g/dL, and 14.84 (±4.65)%, respectively. Multivariate logistic regression revealed that having family history of iron deficiency anemia (OR 2.91, 95% CI 1.78–4.76) and infrequent intake of meat (OR 1.54, 95%CI 1.15–2.05) were associated with increased risk of anemia, whereas increasing body mass index (OR 0.95, 95% CI 0.92–0.97) was associated with reduced risk of anemia. Conclusion. Women should be educated about proper diet and reproductive issues in order to reduce the prevalence of anemia in Saudi Arabia. PMID:24205435

    This study examined the convergence and divergence in mothers’ and children’s reports of maternal support following disclosures of childhood sexual abuse (CSA). One hundred and twenty mothers and their children (ages 7 to 17 years) reported on two aspects of support following CSA disclosures: mothers’ belief in the child’s disclosure and parent-child discussion of the abuse incident. Whereas 62% of mothers’ and children’s reports on mothers’ belief of the disclosure positively converged (i.e., both reported that mothers “completely believed” the child’s disclosure), 37% of mothers’ and children’s reports diverged, and the remaining 1% negatively converged (i.e., both reported that the mother only believed the child “somewhat”). Positively convergent responses were associated with youths’ lower risk for tobacco and illicit drug use. Forty four percent of mothers’ and children’s reports on whether details of the CSA were discussed positively converged (i.e., both reported that details were discussed), 33% diverged, and 23% negatively converged (i.e., both reported that details were not discussed). Relative to other patterns of reporting, negatively convergent responses were associated with higher levels of trauma symptoms. Findings have implications for identifying high-risk mother-child dyads based on patterns of informant reporting following CSA. PMID:24456741

    Purpose The purpose of this study was to develop an algorithm to automatically standardize the brightness, contrast, and color balance of digital color fundus photographs used to grade AMD and to validate this algorithm by determining the effects of the standardization on image quality and disease grading. Methods Seven-field color photographs of patients (>50 years) with any stage of AMD and a control group were acquired at two study sites, with either the Topcon TRC-50DX or Zeiss FF-450 Plus cameras. Field 2 photographs were analyzed. Pixel brightness values in the red, green, and blue (RGB) color channels were adjusted in custom-built software to make the mean brightness and contrast of the images equal to optimal values determined by the Age-Related Eye Disease Study (AREDS) 2 group. Results Color photographs of 370 eyes were analyzed. We found a wide range of brightness and contrast values in the images at baseline, even for those taken with the same camera. After processing, image brightness variability (brightest image–dimmest image in a color channel) was reduced 69-fold, 62-fold, and 96-fold for the RGB channels. Contrast variability was reduced 6-fold, 8-fold, and 13-fold, respectively, after adjustment. Of the 23% images considered nongradable before adjustment, only 5.7% remained nongradable. Conclusions This automated software enables rapid and accurate standardization of color photographs for AMD grading. Translational Relevance This work offers the potential to be the future of assessing and grading AMD from photos for clinical research and teleimaging. PMID:28316876

    Objectives. To provide prevalence and trends of underweight, overweight, and obesity among reproductive-age women and adolescent girls in rural China. Methods. We measured weight and height in 16 742 344 women aged 20 to 49 years and 178 556 girls aged 15 to 19 years from the National Free Preconception Health Examination Project between 2010 and 2014. Results. Among women, the prevalence of underweight was 7.8% (95% confidence interval [CI] = 7.7%, 7.9%), and overweight or obesity was 16.5% (95% CI = 16.4%, 16.6%; World Health Organization criteria). Among adolescents, prevalence of underweight was 6.0% (95% CI = 5.7%, 6.2%; Centers for Disease Control and Prevention criteria) and overweight or obesity was 8.3% (95% CI = 7.9% to 8.8%; International Obesity Task Force criteria). According to Chinese criteria, overweight and obesity prevalence was 24.8% (95% CI = 24.7%, 24.9%) for women and 17.2% (95% CI = 16.6%, 17.8%) for adolescents, and underweight prevalence was 2.9% (95% CI = 2.8%, 3.1%) for adolescents. Considerable disparities existed in prevalence and trends within subpopulations (age groups, parity, region, education levels, and socioeconomic status). Conclusions. Our results reveal coexisting underweight and overweight or obesity among rural women and adolescents of reproductive age, which requires public health attention. PMID:27831775

    Introduction Various dermatoses, due to their morbidity characteristics, have been shown to negatively impact on learning. The most epidemiologically important seem to be the infectious types because of their transmissibility and amenability to simple school-health measures. The aim of this study was to assess the prevalence and sex/age correlates of infectious dermatoses in a rural South-eastern Nigerian community. Methods The pupils were proportionately recruited from the three primary schools based on school population. Stratified simple random sampling method was adopted and a table of random numbers was used to select required pupils from each arm. Clinical and laboratory examination was done to establish diagnoses of infectious skin disease. Data collected were analyzed using SPSS version 16. Results The 400 pupils consisted of 153 males and 247 females. Age range was between 6 and 12 years. The prevalence of infectious dermatoses was 72.3%. The five most prevalent clinical forms of infectious dermatoses, in order of decreasing prevalence, were tinea capitis (35.2%), scabies (10.5%), tinea corporis (5.8%), tinea pedis (5.5%), and impetigo (5.0%). More cases, generally, occurred among males than females (80.4% vs 67.2%)); while some specific clinical types, pediculosis and seborrheic dermatitis, exhibited predilection for females. Pyodermas and scabies were significantly more prevalent in the 7-9 age-group; while tinea capitis, tinea corporis, seborrheic dermatitis and pediculosis were more associated with ≥10 age-group. Conclusion Infectious dermatoses were highly prevalent in the surveyed population. Many of the clinical types exhibited sex- and age-specificity. PMID:26430479

    Aims/Introduction To provide age- and sex-specific trends, age-standardized trends, and projections of diabetes prevalence through the year 2030 in the Japanese adult population. Materials and Methods In the present meta-regression analysis, we included 161,087 adults from six studies and nine national health surveys carried out between 1988 and 2011 in Japan. We assessed the prevalence of diabetes using a recorded history of diabetes or, for the population of individuals without known diabetes, either a glycated hemoglobin level of ≥6.5% (48 mmol/mol) or the 1999 World Health Organization criteria (i.e., a fasting plasma glucose level of ≥126 mg/dL and/or 2-h glucose level of ≥200 mg/dL in the 75-g oral glucose tolerance test). Results For both sexes, prevalence appeared to remain unchanged over the years in all age categories except for men aged 70 years or older, in whom a significant increase in prevalence with time was observed. Age-standardized diabetes prevalence estimates based on the Japanese population of the corresponding year showed marked increasing trends: diabetes prevalence was 6.1% among women (95% confidence interval [CI] 5.5–6.7), 9.9% (95% CI 9.2–10.6) among men, and 7.9% (95% CI 7.5–8.4) among the total population in 2010, and was expected to rise by 2030 to 6.7% (95% CI 5.2–9.2), 13.1% (95% CI 10.9–16.7) and 9.8% (95% CI 8.5–12.0), respectively. In contrast, the age-standardized diabetes prevalence using a fixed population appeared to remain unchanged. Conclusions This large-scale meta-regression analysis shows that a substantial increase in diabetes prevalence is expected in Japan during the next few decades, mainly as a result of the aging of the adult population.

    The aim of the current study was to estimate the prevalence of all primary headaches and cranial neuralgias in the general community. As part of the population-based Bruneck Study, 574 men and women aged 55-94 years underwent extensive neurological and laboratory examinations involving a standardized headache interview. In the Bruneck Study population the lifetime prevalence of all primary headaches combined and of cranial neuralgias was 51.7 and 1.6%, respectively. Tension-type headache (40.9%) and migraine (19.3%) emerged as the most common types of headache. In men and women aged 55-94 years the 1-year prevalence of primary headaches was high at 40.5%. In this age range headaches caused significant impairment of health-related quality of life. The Bruneck Study has confirmed the high lifetime prevalence of primary headaches and cranial neuralgias in the general population and provided first valid prevalence data for all primary headaches based on International Classification of Headache Disorders, 2nd edition criteria.

    One thousand and one men, aged 35-65 years, were identified from the age-sex register of one group general practice. Over four years 900 men were visited at home and asked questions about symptoms potentially related to sleep apnoea and snoring. Height, weight, neck circumference, resting arterial oxygen saturation (SaO2), and spirometric values were also determined. All night oximetry was then performed at home and the tracing analysed for the number of dips in SaO2 of more than 4%. Subjects with more than five dips of 4% SaO2 or more per hour were invited for sleep laboratory polysomnography. Seventeen per cent of the men admitted to snoring "often." Multiple linear regression techniques identified and ranked neck circumference (r2 = 7.2%), cigarette consumption (r2 = 3.4%), and nasal stuffiness (r2 = 2%) as the only significant independent predictors of snoring. Together these account for at least a sixfold variation in the likelihood of being an "often" snorer. Forty six subjects (5%) had greater than 4% SaO2 dip rates of over five an hour and 31 of these had full sleep studies. Three subjects had clinically obvious and severe symptomatic obstructive sleep apnoea, giving a prevalence of three per 1001 men (0.3%; 95% confidence interval 0.07-0.9%). Eighteen men had obstructive sleep apnoea only when supine and in 10 the cause of the SaO2 dipping on the original home tracing was not elucidated. The greater than 4% SaO2 dip rates correlated with the history of snoring. Multiple linear regression techniques identified and ranked neck circumference (r2 = 7.9%), alcohol consumption (r2 = 3.7%), age (r2 = 1%) and obesity (r2 = 1%) as the only significant independent predictors of the rate of overnight hypoxic dipping. This study shows that snoring in this randomly selected population correlates best with neck size, smoking, and nasal stuffiness. Obstructive sleep apnoea, defined by nocturnal hypoxaemia, correlates best with neck size and alcohol, and less so with age

    The aims of this study were to examine the prevalence and correlates of psychological distress among older women living with HIV in comparison to their male counterparts and younger women and to identify the sociodemographic and disease-related factors associated with psychological distress. The sample consisted of 508 HIV-infected patients (65 older women, 323 women aged below 50 years, and 120 older men) recruited from 10 Portuguese hospitals. Data regarding psychological distress were collected using the Brief Symptom Inventory (BSI). Seven older women (10.8%), eight older men (6.7%), and 61 younger women (18.9%) reported a T-score ≥ 63 for global severity index (GSI), indicative of a need for further psychological evaluation. Overall, younger women reported significantly higher psychological distress than older men. The odds of having clinically significant psychological distress score were significantly lower for older women reporting sexual transmission, while for younger women, having other co-infections was a significant correlate of higher psychological distress. Younger women were 2.67 (95% CI: 1.22-5.84) times more likely to report psychological distress than were older men. The odds were not significantly different from older women. This study shows that older women do not differ substantially from younger women and older men in terms of psychological distress. The results reinforce, however, that mental health interventions should be tailored to reflect individuals' circumstances as well as developmental contexts. Moreover, they draw attention to the importance of examining resilience characteristics in older adults to understand the mechanisms behind 'successful ageing' while living with HIV.

    Background Childhood obesity is one of the most serious public health challenges of the 21st century. The prevalence of overweight and obesity among children (<5 years) in Cameroon, based on weight-for-height index, has doubled between 1991 and 2006. This study aimed to determine the prevalence and risk factors of overweight and obesity among children aged 6 months to 5 years in Cameroon in 2011. Methods Four thousand five hundred and eighteen children (2205 boys and 2313 girls) aged between 6 to 59 months were sampled in the 2011 Demographic Health Survey (DHS) database. Body Mass Index (BMI) z-scores based on WHO 2006 reference population was chosen to estimate overweight (BMI z-score > 2) and obesity (BMI for age > 3). Regression analyses were performed to investigate risk factors of overweight/obesity. Results The prevalence of overweight and obesity was 8% (1.7% for obesity alone). Boys were more affected by overweight than girls with a prevalence of 9.7% and 6.4% respectively. The highest prevalence of overweight was observed in the Grassfield area (including people living in West and North-West regions) (15.3%). Factors that were independently associated with overweight and obesity included: having overweight mother (adjusted odds ratio (aOR) = 1.51; 95% CI 1.15 to 1.97) and obese mother (aOR = 2.19; 95% CI = 155 to 3.07), compared to having normal weight mother; high birth weight (aOR = 1.69; 95% CI 1.24 to 2.28) compared to normal birth weight; male gender (aOR = 1.56; 95% CI 1.24 to 1.95); low birth rank (aOR = 1.35; 95% CI 1.06 to 1.72); being aged between 13–24 months (aOR = 1.81; 95% CI = 1.21 to 2.66) and 25–36 months (aOR = 2.79; 95% CI 1.93 to 4.13) compared to being aged 45 to 49 months; living in the grassfield area (aOR = 2.65; 95% CI = 1.87 to 3.79) compared to living in Forest area. Muslim appeared as a protective factor (aOR = 0.67; 95% CI 0.46 to 0.95).compared to Christian religion. Conclusion This study underlines a high prevalence of

    Antimicrobial resistance levels were examined for 365 Salmonella isolates recovered from the lymph nodes (n = 224) and cecal contents (n = 141) of market-age swine at slaughter. Antimicrobial resistance testing was performed by disk diffusion using 13 antibiotics common in the treatment of disease in human and veterinary medicine. Although none of the antibiotics tested were used subtherapeutically within the last 5 years on the farms sampled, resistance to chlortetracycline, penicillin G, streptomycin, and sulfisoxazole was common. Penicillin G resistance was significantly more frequent (P = 0.03) and sulfisoxazole resistance was significantly less frequent (P < 0.01) in lymph node versus cecal isolates. Multidrug resistance was observed among 94.7% of the lymph node isolates and 93.5% of the cecal isolates. The most frequent multidrug resistance pattern included three antibiotics-penicillin G, streptomycin, and chlortetracycline. Isolates in somatic serogroup B, and more specifically, Salmonella Agona and Salmonella Schwarzengrund isolates, were often resistant to a greater number of antibiotics than were isolates in the other serogroups. Streptomycin, sulfisoxazole, ampicillin (lymph node isolates), and nitrofurantoin (cecal isolates) resistance levels differed significantly between somatic serogroups. The prevalence of penicillin G-, streptomycin-, and sulfisoxazole-resistant isolates differed significantly between serovars for both lymph node and cecal isolates. Results of this study suggest that a correlation exists between the somatic serogroup or serovar of a Salmonella isolate and its antimicrobial resistance status, which is specific to the antibiotic of interest and the source of the isolate (lymph node versus cecal contents).

    Campylobacter successfully colonizes broiler chickens, but little is known about the longer term natural history of colonization, since most flocks are slaughtered at an immature age. In this study, the prevalence and genetic diversity of Campylobacter colonizing a single free-range broiler breeder flock was investigated over the course of a year. The age of the flock was the most important factor in determining both the prevalence and diversity of Campylobacter over time. There was no correlation with season, temperature, the amount of rain and sunshine, or the dynamics of colonization amongst geographically and temporally matched broiler flocks. The higher prevalence rates coincided with the age at which broiler chickens are typically slaughtered, but then in the absence of bio-security or other intervention methods, and despite changes in flock management, the prevalence fell to significantly lower levels for the remainder of the study. The genetic diversity of Campylobacter increased as the flock aged, implying that genotypes were accumulated within the flock and may persist for a long time. A better understanding of the ecology of Campylobacter within commercial chicken flocks will allow the design of more effective farm-based interventions.

    Objective To reduce the number of unnecessary biopsies in patients with benign prostatic disease, however, without missing significant PCa the present study re-evaluates the age-dependent PSA cut-offs in the Tyrol Prostate Cancer (PCa) early detection program. Patients and Methods The study population included 2225 patients who underwent prostate biopsy due to elevated PSA levels at our department. We divided our patient collective into four age groups: ≤49 years (n = 178), 50-59 years (n = 597), 60-69 years (n = 962) and ≥70 years (n = 488). We simulated different scenarios for PSA cut-off values between 1.25 and 6 ng/mL and fPSA% between 15 and 21% for all four age groups and calculated sensitivity, specificity, confidence intervals and predictive values. Results PCa was detected in 1218 men (54.7%). We found that in combination with free PSA ≤21% the following PSA cut-offs had the best cancer specificity: 1.75 ng/ml for men ≤49 years and 50-59 years, 2.25 ng/ml for men aged 60-69 years and 3.25 ng/ml for men ≥70 years. Using these adjusted PSA cut-off values all significant tumors are recognized in all age groups, yet the number of biopsies is reduced. Overall, one biopsy is avoided in 13 to 14 men (number needed to screen = 13.3, reduction of biopsies = 7.5%) when decision regarding biopsy is done according to the “new” cut-off values instead of the “old” ones. For the different age groups the number needed to screen to avoid one biopsy varied between 9.2 (≤49 years) and 17.4 (50-59 years). Conclusion With “new”, fine-tuned PSA cut-offs we detect all relevant PCa with a significant reduction of biopsies compared to the “old” cut-off values. Optimization of age-specific PSA cut-offs is one step towards a smarter strategy in the Tyrol PCa Early Detection Program. PMID:26218594

    Human papillomavirus (HPV) infection causes cervical cancer and premalignant dysplasia. Type-specific HPV prevalence data provide a basis for assessing the impact of HPV vaccination programmes on cervical cytology. We report high-risk HPV (HR-HPV) type-specific prevalence data in relation to cervical cytology for 24,510 women (age range: 20-64; mean age 40.2 years) recruited into the ARTISTIC trial, which is being conducted within the routine NHS Cervical Screening Programme in Greater Manchester. The most common HR-HPV types were HPV16, 18, 31, 51 and 52, which accounted for 60% of all HR-HPV types detected. There was a marked decline in the prevalence of HR-HPV infection with age, but the proportion due to each HPV type did not vary greatly with age. Multiple infections were common below the age of 30 years but less so between age 30 and 64 years. Catch-up vaccination of this sexually active cohort would be expected to reduce the number of women with moderate or worse cytology by 45%, but the number with borderline or mild cytology would fall by only 7%, giving an overall reduction of 12% in the number of women with abnormal cytology and 27% in the number with any HR-HPV infection. In the absence of broader cross-protection, the large majority of low-grade and many high-grade abnormalities may still occur in sexually active vaccinated women.

    Secondhand smoke (SHS) is a major risk factor for poor health outcomes among women in China, where proportionately few women smoke. This is especially the case as it pertains to women’s reproductive health, specifically migrant women who are exposed to SHS more than the population at large. There are several factors which may increase migrant women’s risk of SHS exposure. This paper aims to investigate the prevalence and associated factors of SHS exposure among internal Chinese migrant women of reproductive age. The data used were derived from the 2014 Chinese Labor Dynamic Survey, a national representative panel survey. The age-adjusted rate of SHS exposure of women of reproductive age with migration experience was of 43.46% (95% CI: 40.73%–46.40%), higher than those without migration experience (35.28% (95% CI: 33.66%–36.97%)). Multivariate analysis showed that participants with a marital status of “Widowed” had statistically lower exposure rates, while those with a status of “Cohabitation” had statistically higher exposure. Those with an undergraduate degree or above had statistically lower SHS exposure. Those with increasing levels of social support, and those who currently smoke or drink alcohol, had statistically higher SHS exposure. Participants’ different work-places had an effect on their SHS exposure, with outdoor workers statistically more exposed. Our findings suggest that urgent tobacco control measures should be taken to reduce smoking prevalence and SHS exposure. Specific attention should be paid to protecting migrant women of reproductive age from SHS. PMID:27043604

    After an extensive vaccination policy, Japanese encephalitis (JE) was nearly eliminated since the mid-1980s in South Korea. Vaccination in children shifted the affected age of JE patients from children to adults. However, an abrupt increase in JE cases occurred in 2010, and this trend has continued. The present study aimed to investigate the prevalence of neutralizing antibodies to the JE virus (JEV) among high-risk age groups (≥40 years) in South Korea. A plaque reduction neutralization test was conducted to evaluate the prevalence of neutralizing antibodies to JEV in 945 subjects within four age groups (30-39, 40-49, 50-59, and 60-69 years) in 10 provinces. Of the 945 enrolled subjects, 927 (98.1%) exhibited antibodies against JEV. No significant differences were found in the prevalence of neutralizing antibodies according to sex, age, or occupation. However, there were significant differences in the plaque reduction rate according to age and occupation; oldest age group had a higher reduction rate, and subjects who were employed in agriculture or forestry also had a higher value than the other occupations. We also found that three provinces (Gangwon, Jeonnam, and Gyeongnam) had a relatively lower plaque reduction rate than the other locations. In addition, enzyme-linked immunosorbent assays were conducted to determine recent viral infections and 12 (1.3%) subjects were found to have been recently infected by the virus [corrected]. In conclusion, the present study clearly indicated that the prevalence of neutralizing antibodies has been maintained at very high levels among adult age groups owing to vaccination or natural infections, or both. In the future, serosurveillance should be conducted periodically using more representative samples to better understand the population-level immunity to JE in South Korea.

    Previous studies have demonstrated the importance of eating behaviour regarding dietary variety and nutrient intake of children. However, the association between picky eating and growth of children is still a topic of debate. This study sought to estimate the prevalence of picky eating and to identify possible associations with the growth of school-age children in China. In this survey, 793 healthy children aged 7-12 years were recruited from nine cities and rural areas in China using a multi-stage cluster sampling method. Data collected included socio-demographic information and parents' perceptions of picky eating using a structured questionnaire, nutrient intake using 24-hour dietary recall, weight and height using body measurements, and intelligence using the Wechsler Intelligence Scale for Children. Blood samples were collected and analysed for minerals. The prevalence of picky eating reported by parents was 59.3% in children. Compared with non-picky eaters, picky eaters had a lower dietary intake of energy, protein, carbohydrates, most vitamins and minerals, and lower levels of magnesium, iron, and copper in the blood (p < 0.05), and also had a 0.184 z-score lower in height for age (95% CI: -0.332, 0.036; p = 0.015), a 0.385 z-score lower in weight for age (95% CI: -0.533, -0.237; p < 0.001), a 0.383 z-score lower in BMI for age (95% CI: -0.563, -0.203; p < 0.001), and scored 2.726 points higher on the intelligence test (95% CI: 0.809, 4.643; p = 0.006) when adjusted for children's birth weight and food allergy, mothers' education, and family income. Picky eating behaviour towards meat, eggs and vegetables showed negative associations with growth. Picky eating behaviour is prevalent in school-age children in China and may have a negative effect on growth.

    Diagnostic testing is recommended in women with "ovarian cancer symptoms." However, these symptoms are nonspecific. The ongoing Diagnosing Ovarian Cancer Early (DOVE) Study in Montreal, Quebec, Canada, provides diagnostic testing to women aged 50 years or older with symptoms lasting for more than 2 weeks and less than 1 year. The prevalence of ovarian cancer in DOVE is 10 times that of large screening trials, prompting us to estimate the prevalence of these symptoms in this population. We sent a questionnaire to 3,000 randomly sampled women in 2014-2015. Overall, 833 women responded; 81.5% reported at least 1 symptom, and 59.7% reported at least 1 symptom within the duration window specified in DOVE. We explored whether such high prevalence resulted from low survey response by applying inverse probability weighting to correct the estimates. Older women and those from deprived areas were less likely to respond, but only age was associated with symptom reporting. Prevalence was similar in early and late responders. Inverse probability weighting had a minimal impact on estimates, suggesting little evidence of nonresponse bias. This is the first study investigating symptoms that have proven to identify a subset of women with a high prevalence of ovarian cancer. However, the high frequency of symptoms warrants further refinements before symptom-triggered diagnostic testing can be implemented.

    Background. Cognitive impairment is an important clinical issue among elderly patients with depression and has a more complex etiology because of the variable rate of neurodegenerative changes associated with depression. The aim of the present work was to examine the prevalence of cognitive impairment and depression in a representative sample of adults aged ≥60 years. Methods. The presented work was a cross-sectional study on the prevalence of cognitive impairment and depression. Door-to-door interview technique was assigned in condition with multistage probability random sampling to obtain subjects that represent a population of the Guadalajara metropolitan area (GMA), Mexico. Cognitive function and depression were assessed by applying standardized Mini-Mental State Examination of Folstein (MMSE) and the Geriatric Depression Scale (GDS), respectively. Results. Prevalence of cognitive impairment was 13.8% (14.5% women, 12.6% men); no significant differences by gender and retired or pensioner were found. Prevalence of depression was 29.1% (33.6% women, 21.1% men); no significant differences by retired or pensioner were found. Cognitive impairment was associated with depression (OR  =  3.26, CI 95%, 2.31–4.60). Prevalence of cognitive impairment and depression is associated with: being woman, only in depression being older than 75 years being married, and a low level of education. Conclusion. Cognitive impairment and depression are highly correlated in adults aged ≥60. PMID:23243421

    The objective of the study was to compare the prevalence of self-reported physician-diagnosed asthma and age at asthma onset between Swedish adolescent elite skiers and a reference group and to assess risk factors associated with asthma. Postal questionnaires were sent to 253 pupils at the Swedish National Elite Sport Schools for cross-country skiing, biathlon, and ski-orienteering ("skiers") and a random sample of 500 adolescents aged 16-20, matched for sport school municipalities ("reference"). The response rate was 96% among the skiers and 48% in the reference group. The proportion of participants with self-reported physician-diagnosed asthma was higher among skiers than in the reference group (27 vs. 19%, p = 0.046). Female skiers reported a higher prevalence of physician-diagnosed asthma compared to male skiers (34 vs. 20%, p = 0.021). The median age at asthma onset was higher among skiers (12.0 vs. 8.0 years; p < 0.001). Female sex, family history of asthma, nasal allergy, and being a skier were risk factors associated with self-reported physician-diagnosed asthma. Swedish adolescent elite cross-country skiers have a higher asthma prevalence and later age at asthma onset compared to a reference population. Being an adolescent elite skier is an independent risk factor associated with asthma. This article is protected by copyright. All rights reserved.

    The gastrointestinal helminth infection status of 1574 children living in a slum area of Kuala Lumpur, Malaysia was assessed by quantitative coprology. Almost two-thirds were infected with Trichuris trichiura, 49.6% with Ascaris lumbricoides, and 5.3% with hookworm. Infection prevalence rose rapidly to a stable asymptote at 7 years of age, and the age-intensity profile was convex with maximal values in the 5-10 year age classes. This pattern was the same for males and females, but differed markedly between different ethnic groups. The frequency distributions of A. lumbricoides and T. trichiura were highly overdispersed (k values were 0.21 and 0.27, respectively), and age-dependent over the 0-8 year age classes. This suggests that the force of infection with these nematodes is lower in infants than in older children.

    2014-01-01

    Background Population-based studies for prevalence of metabolic syndrome (M.S) in children and adolescents are relatively rare. The aim of this study was to assess the Prevalence of M.S and correlated factors among children and adolescents aged 10 to 19 years in Ahvaz. Methods In this descriptive-analytical population- based study, 2246 children and adolescents, 10–19 years old (1113 male and 1133 female) in Ahvaz, were evaluated. Anthropometry, biochemical measurement and blood pressure (BP) were assessed. Modified ATP III criteria 2005 were used for M.S. definition. Center for disease and Control preventions (CDC) percentile were applied to define cut off points of waist circumference and BP. Results Prevalence of M.S. was 9% (95% CI: 8-10%) with prevalence in male 11% (95% CI: 10-12%) and female 7% (95% CI 6-8%). Among individuals with M.S, triglyceride (TG) and decreased high density lipoprotein (HDL) cholesterol levels were the most common components (33.5% and 24.1%, respectively). Prevalence of M.S was higher in overweight persons comparing to participants with at risk and normal weight group (in male: 24.1%, 14.3% and 9.9% respectively P = 0.0001), (in female: 22.6%, 18.3% and 4.5% respectively P = 0.0001). Among the correlated factors of M.S age (P = 0.0006), sex and BMI (P = 0.0001) had significant differences between subjects with and without M.S. whereas there was no significant difference between two groups in ethnicity, history of breast fed, birth weight neonatal ICU admission, maternal history(GDM, gestational HTN, Parity) and family history of HTN, obesity and DM (P > 0.05). Conclusion This study shows high prevalence of M.S in Children and Adolescents in south west of Iran (Ahvaz) especially in overweight persons. PMID:24860794

  2. Socioeconomic status and the prevalence of fever in children under age five: evidence from four sub-Saharan African countries

    PubMed Central

    2012-01-01

    Background The burden of fevers remains enormous in sub-Saharan Africa. While several efforts at reducing the burden of fevers have been made at the macro level, the relationship between socioeconomic status and fever prevalence has been inconclusive at the household and individual levels. The purpose of this study was to examine how individual and household socioeconomic status influences the prevalence of fever among children under age five in four sub-Saharan African countries. Methods The study used data from the 2008 Demographic and Health Survey (DHS) from Ghana, Nigeria, Kenya and Sierra Leone with a total of 38,990 children below age five. A multi-level random effects logistic model was fitted to examine the socioeconomic factors that influence the prevalence of fever in the two weeks preceding the survey. Data from the four countries were also combined to estimate this relationship, after country-specific analysis. Results The results show that children from wealthier households reported lower prevalence of fever in Ghana, Nigeria and Kenya. Result from the combined dataset shows that children from wealthier households were less likely to report fever. In general, vaccination against fever-related diseases and the use of improved toilet facility reduces fever prevalence. The use of bed nets by children and mothers did not show consistent relationship across the countries. Conclusion Poverty does not only influence prevalence of fever at the macro level as shown in other studies but also the individual and household levels. Policies directed towards preventing childhood fevers should take a close account of issues of poverty alleviation. There is also the need to ensure that prevention and treatment mechanisms directed towards fever related diseases (such as malaria, pneumonia, measles, diarrhoea, polio, tuberculosis etc.) are accessible and effectively used.

    2006-01-01

    To estimate adjustment factors and genetic parameters for gestation length (GES), AI and calving date records (n = 40,356) were extracted from the Canadian Charolais Association field database. The average time from AI to calving date was 285.2 d (SD = 4.49 d) and ranged from 274 to 296 d. Fixed effects were sex of calf, age of dam (2, 3, 4, 5 to 10, > or = 11 yr), and gestation contemporary group (year of birth x herd of origin). Variance components were estimated using REML and 4 animal models (n = 84,332) containing from 0 to 3 random maternal effects. Model 1 (M1) contained only direct genetic effects. Model 2 (M2) was G1 plus maternal genetic effects with the direct x maternal genetic covariance constrained to zero, and model 3 (M3) was G2 without the covariance constraint. Model 4 (M4) extended G3 to include a random maternal permanent environmental effect. Direct heritability estimates were high and similar among all models (0.61 to 0.64), and maternal heritability estimates were low, ranging from 0.01 (M2) to 0.09 (M3). Likelihood ratio tests and parameter estimates suggested that M4 was the most appropriate (P < 0.05) model. With M4, phenotypic variance (18.35 d2) was partitioned into direct and maternal genetic, and maternal permanent environmental components (hd2 = 0.64 +/- 0.04, hm2 = 0.07 +/- 0.01, r(d,m) = -0.37 +/- 0.06, and c2 = 0.03 +/- 0.01, respectively). Linear contrasts were used to estimate that bull calves gestated 1.26 d longer (P < 0.02) than heifers, and adjustments to a mature equivalent (5 to 10 yr old) age of dam were 1.49 (P < 0.01), 0.56 (P < 0.01), 0.33 (P < 0.01), and -0.24 (P < 0.14) d for GES records of calves born to 2-, 3-, 4-, and > or = 11-yr-old cows, respectively. Bivariate animal models were used to estimate genetic parameters for GES with birth and adjusted 205-d weaning weights, and postweaning gain. Direct GES was positively correlated with direct birth weight (BWT; 0.34 +/- 0.04) but negatively correlated with maternal

    In 2014, the top five causes of cancer deaths for the total population were lung, colorectal, female breast, pancreatic, and prostate cancer. The non-Hispanic black population had the highest age-adjusted death rates for each of these five cancers, followed by non-Hispanic white and Hispanic groups. The age-adjusted death rate for lung cancer, the leading cause of cancer death in all groups, was 42.1 per 100,000 standard population for the total population, 45.4 for non-Hispanic white, 45.7 for non-Hispanic black, and 18.3 for Hispanic populations.

    We examined the prevalence of lead exposure from ingestion of waste lead shot among age and sex cohorts of Canada geese (Branta canadensis) on the breeding, migration, and wintering grounds of the Eastern Prairie Population. Blood samples from 6963 geese were assayed for lead concentration by atomic absorption spectrophotometry. On the breeding grounds, no goslings and < 1 % of adults showed evidence of recent exposure to lead shot (i.e., concentrations in the blood elevated above the threshold value of 0. 18 ppm lead). However, median background blood lead concentrations (i.e., blood samples with < 0.18 ppm lead) were higher in adults than goslings, indicating that exposure of adults to lead had occurred during previous seasons. Waste lead shot was available on the migration and wintering grounds, where a larger proportion of the blood samples from immatures (< 1 year old) than adults (> 1 year old) had lead concentrations greater-than-or-equal-to 0.18 ppm. Median background lead levels remained higher in adults than in immatures throughout fall and winter. We also found that more immature males than immature females had elevated lead concentrations. Higher rates of intake of food and grit (including shot) probably partially account for the higher prevalence of elevated lead concentrations in immature Canada geese.//Nous avons ??tudi?? l'importance des expositions au plomb par ingestion de plombs de chasse chez les diff??rentes cohortes (??ge et sexe) de Bernaches du Canada (Branta canadensis) dans les zones de reproduction et de migration et dans les territoires d'hiver chez la population de la Prairie de l'Est.

    In bipedal gait, the initiation of the first step is preceded by a complex sequence of movements which shift the centre of mass of the body towards the stance foot to allow for a step of the swing foot. These anticipatory postural adjustments (APAs) have been investigated in order to elucidate movement strategies in healthy and diseased persons. We studied the influence of several external parameters (age, type of step initiation) on APAs and investigated whether Parkinsonian patients may have different APAs. As a result, we found that externally elicited steps were preceded by faster and larger APAs than self-timed steps. Parkinsonian patients without the freezing of gait (FOG) phenomenon showed overall slightly reduced APAs but did not clearly differ from patients with FOG. Multiple APAs were seen in up to 25 % of the steps of the patients and in a much lower percentage of the steps of control subjects. The results indicate that APAs are significantly influenced by the timing of a step, i.e. are larger in externally elicited steps. The patients showed an overall preserved APA pattern but slowed movements and amplitude, indicating that increased bradykinesia due to progressive illness is a plausible explanation for these findings. The freezing phenomenon is not explained by a general absence or massive reduction in APA measures.

    The optical morphology of galaxies holds the cumulative record of their assembly history, and techniques for its quantitative characterization offer a promising avenue toward understanding galaxy formation and evolution. However, the morphology of star-forming galaxies is generally dictated by the youngest stellar component, which can readily overshine faint structural/morphological features in the older underlying stellar background (e.g., relics from recent minor mergers) that could hold important insights into the galaxy build-up process. Stripping off galaxy images from the emission from stellar populations younger than an adjustable age cutoff tcut can therefore provide a valuable tool in extragalactic research. RemoveYoung (), a publicly available tool that is presented here, exploits the combined power of integral field spectroscopy (IFS) and spectral population synthesis (SPS) toward this goal. Two-dimensional (2D) post-processing of SPS models to IFS data cubes with permits computation of the spectral energy, surface brightness, and stellar surface density distribution of stellar populations older than a user-defined tcut. This suggests a variety of applications of star-forming galaxies, such as interacting or merging galaxy pairs and lower mass starburst galaxies near and far; these include blue compact and tidal dwarf galaxies.

    Bone marrow harvested by aspiration contains connective tissue progenitor cells which can be induced to express a bone phenotype in vitro. The number of osteoblastic progenitors can be estimated by counting the colony-forming units which express alkaline phosphatase (CFU-APs). This study was undertaken to test the hypothesis that human aging is associated with a significant change in the number or prevalence of osteoblastic progenitors in the bone marrow. Four 2-ml bone marrow aspirates were harvested bilaterally from the anterior iliac crest of 57 patients, 31 men (age 15-83) and 26 women (age 13-79). A mean of 64 million nucleated cells was harvested per aspirate. The mean prevalence of CFU-APs was found to be 55 per million nucleated cells. These data revealed a significant age-related decline in the number of nucleated cells harvested per aspirate for both men and women (P = 0.002). The number of CFU-APs harvested per aspirate also decreased significantly with age for women (P = 0.02), but not for men (P = 0.3). These findings are relevant to the harvest of bone marrow derived connective tissue progenitors for bone grafting and other tissue engineering applications, and may also be relevant to the pathophysiology of age-related bone loss and post-menopausal osteoporosis.

  9. The Prevalence of Nocturia and Nocturnal Polyuria: Can New Cutoff Values Be Suggested According to Age and Sex?

    PubMed Central

    2016-01-01

    Purpose The aims of this study were to assess the prevalence of nocturia and nocturnal polyuria (NP) and to define new cutoff values according to age and sex for both conditions. Methods Data from a population-based prevalence survey conducted among a random sample of 2,128 adults were analyzed in this study. Participants were requested to fill out a questionnaire including the International Continence Society (ICS) definitions of lower urinary tract symptoms and the International Consultation on Incontinence Questionnaire - Short Form. Additionally, a 1-day bladder diary was given to each individual. The participants were divided into 5 age groups. The prevalence of nocturia was calculated based on definitions of nocturia as ≥1 voiding episodes, ≥2 episodes, and ≥3 episodes. NP was evaluated according to the ICS definition. The mean±standard errors and 95th percentile values were calculated in each group as new cutoff values for NP. Results The prevalence of nocturia was estimated as 28.4%, 17.6%, and 8.9% for ≥1, ≥2, and ≥3 voiding episodes each night, respectively. When nocturia was defined as 2 or more voiding episodes at night, the prevalence decreased significantly. The mean NP index was 29.4%±15.0% in men and 23.1%±11.8% in women. For the age groups of <50 years, 50–59 years, and ≥60 years, the new cutoff values for the diagnosis of NP were calculated as 48%, 69%, and 59% for men and 41%, 50%, and 42% for women, respectively. Conclusions We found that the definition of nocturia was still controversial and that waking up once for voiding might be within the normal spectrum of behavior. The definition of NP should be modified, and new cutoff values should be defined using the data presented in our study and in other forthcoming studies. PMID:28043108

    The range and infestation intensities of gastrointestinal parasitic nematode species depend on the type of swine production system. The present study focused mainly on nematodes of veterinary importance in scavenging pigs in Burkina Faso, and aimed at determining the prevalence of gastro-intestinal nematode parasites by means of faecal egg per gram (EPG) counts. Between November 2001 and October 2002, faecal samples from 383 pigs of different sexes and ages (< 5 months, 5-12 months and > 12 months) were collected from the rectum and examined for gastrointestinal nematodes parasites using the Mc Master method. Of the 383 pigs examined, 91% were infected by one or more parasites. Ascaris suum (40%; 100-1 400 EPG) was the most prevalent parasite followed by Strongyloides ransomi (21%; 100-4200 EPG), Oesophagostomum spp. (18%; 100-1000 EPG), Hyostrongylus rubidus (11%; 100-1 800 EPG), Globocephalus spp. (10%; 100-400 EPG) and Trichuris suis (1 %; 100-200 EPG). The prevalence was significantly higher in female pigs (n = 239) than in males. In addition, females excreted significantly (P < 0.05) more eggs in their faeces than males, except in the case of Globocephalus spp. The age of the animal had no effect on the prevalence of A. suum whereas there were significant differences in age categories concerning S. ransomi, H. rubidus, Oesophagostumum spp. and Globocephalus spp. Unexpectedly, the high prevalence of these common parasites was not accompanied by elevated EPG values, which suggests the existence of moderate infestations. The present work indicates that the common nematode infestations in pigs do not necessarily need a systematic herd anthelmintic treatment, as only a small number of worms is required to induce immunity. A further study is needed to formulate appropriate and cost-effective strategies for the control of gastro-intestinal nematode parasites in pigs in Burkina Faso.

    Systemic inflammation promotes cardiovascular disease. Inflammatory connective tissue diseases (CTD) like lupus and rheumatoid arthritis associate with cardiovascular risk, but it is unknown whether particular groups of patients have enhanced propensity for atherosclerotic cardiovascular disease (ASCVD) associated with their CTD. Analysis of aggregate health record data at a large U.S. academic center identified CTD and ASCVD status for 287,467 African American and white adults. ASCVD prevalence in those with CTD was 29.7% for African Americans and 14.7% for white patients with prevalence ratios, compared to those without CTD, of 3.1 and 1.8, respectively. When different types of CTD were analyzed individually (rheumatoid arthritis; lupus; scleroderma; Sjögren Syndrome; dermatomyositis/polymyositis; unspecified/mixed CTD; other inflammatory arthropathy), increased ASCVD rates were found in nearly all subsets, always with higher prevalence ratios in African Americans. The prevalence ratio of ASCVD was particularly high in young African Americans. Furthermore, individuals lacking traditional cardiovascular risk factors had more ASCVD if they had CTD (prevalence ratio 2.9). Multivariate analysis confirmed a positive interaction between CTD and African-American race and a negative interaction between CTD and age. The factors driving the observed disproportionate CTD-associated ASCVD in African Americans, young adults, and those without traditional risk factors warrant further study. PMID:26842423

    Aim Hypercalciuria is an important cause of urinary tract symptoms, and also frequently results in urolithiasis. Urinary calcium excretion varies for geographic areas. We aimed to assess percentiles of urinary calcium excretion and prevalence of hypercalciuria for school-aged children in Tokat (city located in inner northern region of Turkey). Material and Methods One thousand three hundred seventy-five children aged 6 to 18 years were enrolled in the study. Urine samples were obtained randomly. The children’s variables as sex, age, length, and weight were recorded. Urinary calcium and creatinine determined from the urine samples and urinary calcium/creatinine ratios (mg/mg) were calculated. Percentiles of urinary calcium/creatinine ratios were also assessed for each age of the children. Results Six hundred eighty-three of the 1 375 children were girls and 692 were boys. The mean age of the children was 11.68±3.43 years. Some 23.9% of the children were living in rural regions and 76.1% were were living in urban regions. The mean urinary calcium/creatinine ratio was 0.080±0.24 and the 95th percentile value of the urinary calcium/creatinine ratio was 0.278. The hypercalciuria prevalence for school-aged children was 4.7% when the urinary calcium/creatinine ratio value for hypercalciuria was accepted as ≥0.21. The prevalence of hypercalciuria in rural and urban regions was 7.60% and 3.82%, respectively (p<0.05). Hypercalciuria was present in 7 of 141 patients who were obese (4.96%) and 58 of 1 234 patients who were not obese (4.70%) (p>0.05). Conclusion The prevalence of hypercalciuria and urinary calcium excretion vary for different geographic areas, not only for countries. The percentiles of urinary calcium excretion should be assesed for every geographic region and the prevalance of hypercalciuria should be determined with these values. There is controversy as to whether obesity is a risk factor for hypercalciuria. PMID:28123331

Among the five leading causes of death, the age-adjusted rates of three were lower in 2014 than in 1999: cancer (from 19.6 to 15.3, a 22% decline), heart disease (8.9 to 8.2, an 8% decline), and homicide (4.2 to 2.8, a 33% decline). The age-adjusted death rates for two of the five causes were higher in 2014 than in 1999: unintentional injuries (from 17.0 to 20.1, an 18% increase) and suicide (4.8 to 6.5, a 35% increase). Unintentional injuries replaced cancer as the leading cause of death in this demographic group.

    A cross-sectioned study was conducted at the Lefaragatha village of Bophuthatswana to document the prevalence and risk factors for malnutrition in children aged 0-5 years in June 1991. Fifty four households, in which there were children in the right age groups, were interviewed over three weeks. Of these children 14 (25.9%) were below the 3rd percentile of weight for age of the 1976 National Centre for Health Statistics standards; in the age group of 2 years and less, this figure was 28.6%, while in children older than 2 years the corresponding figure was 71.4%. Malnutrition was associated with a mother's consumption of alcohol and lack of resources such as water and an inappropriate staple diet. Education and income were not significant variables.

    Pelvic inflammatory disease (PID) is a clinical syndrome of the female reproductive tract characterized by inflammation of the endometrium, fallopian tubes, or peritoneum (1). PID occurs when microorganisms ascend from the vagina or cervix to the fallopian tubes and other upper genital tract structures (1). PID can result from untreated bacterial infections, including chlamydia and gonorrhea, and can lead to infertility, ectopic pregnancy, and chronic pelvic pain (1). Because there is no single diagnostic test for PID, clinicians rely on nonspecific signs and symptoms for diagnosis. The purpose of these analyses was to assess the burden of self-reported PID in a nationally representative sample using data from the National Health and Nutrition Examination Survey (NHANES) 2013-2014 cycle. Starting in 2013, NHANES female participants aged 18-44 years were asked about a lifetime history of PID diagnosis. Based on these data, the estimated prevalence of self-reported lifetime PID was 4.4% in sexually experienced women of reproductive age (18-44 years). The prevalence of self-reported lifetime PID was highest in women at increased risk, such as women reporting a previous sexually transmitted infection (STI) diagnosis. Stratified by race/ethnicity and having a previous STI diagnosis, non-Hispanic black (black) and non-Hispanic white (white) women reporting a previous STI diagnosis had nearly equal self-reported lifetime PID prevalence (10.0% versus 10.3%). However, the lifetime prevalence of PID among black women was 2.2 times that among white women if no previous STI was diagnosed (6.0% versus 2.7%). These findings suggest that PID is prevalent and associated with previous STI diagnoses; therefore, it is important for clinicians to screen female patients for chlamydia and gonorrhea to reduce the incidence of PID.

    Only limited epidemiological evidence exists regarding the relationship between diabetic neuropathy and erectile dysfunction (ED) among Japanese patients with type 2 diabetes mellitus. To investigate the relationship between diabetic neuropathy and ED among Japanese patients with type 2 diabetes mellitus, a multicenter cross-sectional study was conducted in 287 male Japanese patients with type 2 diabetes mellitus, age (19-65 years). Diabetic neuropathy was diagnosed if the patients showed two or more of the following three characteristics: neuropathic symptoms, decreased or disappeared Achilles tendon reflex and/or abnormal vibration perception. ED, moderate to severe ED, and severe ED were defined as present when a subject had a Sexual Health Inventory for Men score <22, <12 and <8, respectively. The prevalence values of diabetic neuropathy and severe ED were 47.0 and 39.0%, respectively. Diabetic neuropathy was independently positively associated with severe ED, but not ED and moderate ED: the adjusted odds ratio was 1.90 (95% confidence interval: 1.08-3.38). No relationships were found between diabetic retinopathy or diabetic nephropathy and ED. Diabetic neuropathy is positively associated with severe erectile dysfunction among Japanese type 2 diabetes mellitus patients aged <65 years.

    Purpose. To determine the prevalence of age-related eye diseases and cataract surgery among older adults in the city of Lodz, in central Poland. Material and Methods. The study design was cross-sectional and observational study. A total of 1107 women and men of predominantly Caucasian origin were successfully enumerated and recruited for the study. All selected subjects were interviewed and underwent detailed ophthalmic examinations. Results. Overall 8.04% (95% CI 6.44-9.64) subjects had cataract surgery in either eye. After excluding subjects with bilateral cataract surgery, the prevalence of cataract was 12.10% (95% CI 10.18-14.03). AMD was found in 4.33% (95% CI 3.14-5.54 ) of all subjects. Of them 3.25% (95% CI 2.21-4.30 ) had early AMD and 1.08% (95% CI 0.47-1.69) had late AMD. Various types of glaucoma were diagnosed in 5.51% (95% CI 4.17-6.85) of subjects and 2.62% (95% CI 1.68-3.56) had OHT. The prevalence rates of DR and myopic macular degeneration were 1.72% (95% CI 0.95-2.48) and 0.45% (95% CI 0.06-0.85), respectively. All multiple logistic regression models were only significantly associated with older age. The highest rate of visual impairment was observed among subjects with retinal diseases. Conclusions. The study revealed high prevalence of age-related eye diseases in this older population.

    Background Iron deficiency Anemia (IDA) in children is a recognized public health problem that impacts adversely on child morbidity, mortality and impairs cognitive development. In Pakistan information on the true prevalence and predictors of IDA is limited. This study sought to investigate IDA in children under five years of age using data from a nationally representative stratified cross-sectional survey. Methods Secondary analysis was performed on the National Nutrition Survey in Pakistan 2011–2012. We used a pre-structured instrument to collect socio demographic and nutritional data on mothers and children. We also collected Anthropometric measurements and blood samples for micronutrient deficiencies. IDA was defined as having both haemoglobin levels of <110 g/L and ferritin levels of < 12 μg/L. Data analysis was performed by applying univariate and multivariate techniques using logistic regression through SPSS. Findings A total of 7138 children aged between 6–59 months were included in the analysis. The prevalence of IDA was 33.2%. In multivariate regression analysis adjusted odds ratios (AOR) were calculated. Age < 24 months (AOR 1.40, 95% CI 1.18–1.55 p <0.05), stunting (AOR 1.42 CI 1.23–1.63 p<0.05), presence of clinical anemia (AOR 5.69 CI 4.93–6.56 p<0.05), having a mother with IDA (AOR 1.72 CI 1.47–2.01 p<0.05) and household food insecurity (AOR 1.20 CI 1.10–1.40 P<0.05) were associated with IDA. Living in a rural area (AOR 0.77 CI 0.65–0.90 p<0.05) and being a female child (AOR 0.87 CI 0.76–0.98 p<0.05) were associated with reduced odds of IDA. Conclusion The prevalence of IDA amongst Pakistani children represents a moderate burden that disproportionately affects the youngest, growth retarded children, affected children are more likely to have mothers with IDA and live in areas where food security is lacking. National efforts to alleviate the burden of IDA should involve both short term vertical programs such as iron supplementation

    Background The prevalence of high blood pressure in children is increasing worldwide, largely, but not entirely, driven by the concurrent childhood obesity epidemic. The aims of this study were to examine the prevalence of prehypertension and hypertension in 4-to-6-year-old Spanish schoolchildren, and to evaluate the association between different blood pressure (BP) components with different adiposity indicators. Methods Cross-sectional study including a sample of 1.604 schoolchildren aged 4-to-6-years belonging to 21 schools from the provinces of Ciudad Real and Cuenca, Spain. We measured height, weight, body mass index (BMI), fat mass percentage (%FM), triceps skinfold thickness (TST), waist circumference (WC), systolic and diastolic BP, mean arterial pressure and pulse pressure. Results The estimates of prevalence of prehypertension and hypertension were 12.3% and 18.2%, respectively. In both sexes, adiposity indicators were positively and significantly associated with all BP components (p<0.001), thus schoolchildren in the higher adiposity categories had significantly higher BP levels (p<0.001). Conclusions Our results show a high prevalence of high blood pressure in Spanish children. Moreover, high levels of adiposity are associated with high blood pressure in early childhood, which support that it could be related to cardiovascular risk later in life. PMID:28141860

    Context: Variations in morphology of shape of teeth have always been of interest to dentists from ancient times. But to our surprise, till date, no studies related to the prevalence of dental features have been conducted in any part of the world. Aims: To evaluate the prevalence of a few variant dental features in a group of children aged from 11 to 16 years in the city of Davangere that belongs to the state of Karnataka, India. Materials and Methods: A cross-sectional survey was conducted where children aged 11–16 years were selected (both girls and boys) and type III clinical examination was done. They were checked for the following features – Carabelli's cusp, 3-cusped maxillary 2nd molar, 5-cusped maxillary 1st molar, 4-cusped mandibular 1st molar, 5-cusped mandibular 2nd molar, cusp 6 present in mandibular 1st molar, and 7-cusped mandibular 1st molar. Statistical Analysis Used: The Chi-square test was used to analyze the categorical data. P value of 0.05 or less was considered for statistical significance. Results: Around 99.3% of the school children examined had at least one of the dental variations that were examined in relation to the shape of teeth. Conclusions: This study definitely provides us with baseline data, but further epidemiological studies are required to determine the prevalence of the above mentioned dental anomalies. PMID:27051217

    Diversity in lifestyles and socioeconomic status among European populations, and recent socio-political and economic changes in transitional countries, may affect changes in adiposity. We aimed to determine whether change in the prevalence of obesity varies between the socio-politically transitional North-East European (Łódź, Poland; Szeged, Hungary; Tartu, Estonia), and the non-transitional Mediterranean (Santiago de Compostela, Spain; Florence, Italy) and North-West European (Leuven, Belgium; Malmö, Sweden; Manchester, UK) cities. This prospective observational cohort survey was performed between 2003 and 2005 at baseline and followed up between 2008 and 2010 of 3369 community-dwelling men aged 40-79 years. Main outcome measures in the present paper included waist circumference, body mass index and mid-upper arm muscle area. Baseline prevalence of waist circumference ≥ 102 cm and body mass index ≥ 30 kg/m(2), respectively, were 39.0, 29.5 % in North-East European cities, 32.4, 21.9 % in Mediterranean cities, and 30.0, 20.1 % in North-West European cities. After median 4.3 years, men living in cities from transitional countries had mean gains in waist circumference (1.1 cm) and body mass index (0.2 kg/m(2)), which were greater than men in cities from non-transitional countries (P = 0.005). North-East European cities had greater gains in waist circumference (1.5 cm) than in Mediterranean cities (P < 0.001). Over 4.3 years, the prevalence of waist circumference ≥ 102 cm had increased by 13.1 % in North-East European cities, 5.8 % in the Mediterranean cities, 10.0 % in North-West European cities. Odds ratios (95 % confidence intervals), adjusted for lifestyle factors, for developing waist circumference ≥ 102 cm, compared with men from Mediterranean cities, were 2.3 (1.5-3.5) in North-East European cities and 1.6 (1.1-2.4) in North-West European cities, and 1.6 (1.2-2.1) in men living in cities from

    Background Classically we have been taught that the skin prick test (SPT) must be performed over 4 years of age mainly because of the lack of sensibility the test has on younger children, now a days the utility of the SPT in younger children with atopic history is controversial and it would help make an early diagnosis. The objective of this study is to describe the prevalence of allergen sensitization in children between 0 and 5 years of age that have atopic history. We also describe the sensitization percentages to the most relevant allergens according to age group. Methods SPT performed between January 2006 and July 2010 at the Respiratory and Allergy Department of Clínica Santa Maria to children with atopic story were analyzed. A standard base of 21 allergens from LETI laboratory was used. Results Seven hundred and fifty two children with SPT were studied; they were divided into 2 groups. Group A corresponding to children between 6 and 24 months of age, group B corresponding to children between 25 months and 5 years of age. In group A 76 SPT and group B 676 SPT were performed. The total number of SPT positive to 1 or more allergens was 46.4%. (Group A: 6.4%, group B 40%). The most prevalent allergens according to age were: group A: grass 16%, egg 16%, cat dander 10% and house dust mite (Dermatophagoides pteronyssinsus and farinae) 10%. Group B: grass 15%, house dust mite 13.6%, fungal allergens (Aspergillus an Alternaria) 11.4%, trees 9% and cat dander 6.6%. Conclusions A high sensitization percentage to grass and egg is seen under 24 months of age. Egg sensitization diminishes significantly over 2 years of age, on the other hand house dust mite and fungal sensitization increases with age which could be explained by a longer exposure time in genetically predisposed children. Forty-six percent of the children are sensitized to 1 or more allergens which make us question the classical indication that SPT will be done over 4 years of age. When high suspicion of

    Awareness of a patient's clinical status during hospitalization is a primary responsibility for hospital providers. One tool to assess status is the Rothman Index (RI), a validated measure of patient condition for adults, based on empirically derived relationships between 1-year post-discharge mortality and each of 26 clinical measurements available in the electronic medical record. However, such an approach cannot be used for pediatrics, where the relationships between risk and clinical variables are distinct functions of patient age, and sufficient 1-year mortality data for each age group simply do not exist. We report the development and validation of a new methodology to use adult mortality data to generate continuously age-adjusted acuity scores for pediatrics. Clinical data were extracted from EMRs at three pediatric hospitals covering 105,470 inpatient visits over a 3-year period. The RI input variable set was used as a starting point for the development of the pediatric Rothman Index (pRI). Age-dependence of continuous variables was determined by plotting mean values versus age. For variables determined to be age-dependent, polynomial functions of mean value and mean standard deviation versus age were constructed. Mean values and standard deviations for adult RI excess risk curves were separately estimated. Based on the "find the center of the channel" hypothesis, univariate pediatric risk was then computed by applying a z-score transform to adult mean and standard deviation values based on polynomial pediatric mean and standard deviation functions. Multivariate pediatric risk is estimated as the sum of univariate risk. Other age adjustments for categorical variables were also employed. Age-specific pediatric excess risk functions were compared to age-specific expert-derived functions and to in-hospital mortality. AUC for 24-h mortality and pRI scores prior to unplanned ICU transfers were computed. Age-adjusted risk functions correlated well with similar

    Background An increasing proportion of Australia's chronic disease burden is carried by the ageing male. The aim of this study was to determine the prevalence of asthma, cancer, diabetes, angina and musculoskeletal conditions and their relationship to behavioural and socio-demographic factors in a cohort of Australian men. Methods Self-reports of disease status were obtained from baseline clinic visits (August 2002 – July 2003 & July 2004 – May 2005) from 1195 randomly selected men, aged 35–80 years and living in the north-west regions of Adelaide. Initially, relative risks were assessed by regression against selected variables for each outcome. Where age-independent associations were observed with the relevant chronic disease, independent variables were fitted to customized multiadjusted models. Results The prevalence of all conditions was moderately higher in comparison to national data for age-matched men. In particular, there was an unusually high rate of men with cancer. Multiadjusted analyses revealed age as a predictor of chronic conditions (type 2 diabetes mellitus, angina, cancer & osteoarthritis). A number of socio-demographic factors, independent of age, were associated with chronic disease, including: low income status (diabetes), separation/divorce (asthma), unemployment (cancer), high waist circumference (diabetes), elevated cholesterol (angina) and a family history of obesity (angina). Conclusion Socio-demographic factors interact to determine disease status in this broadly representative group of Australian men. In addition to obesity and a positive personal and family history of disease, men who are socially disadvantaged (low income, unemployed, separated) should be specifically targeted by public health initiatives.

    Aim and Objectives: To determine the prevalence of developmental defects of enamel in children aged 12–15 years in Kollam district and to examine the etiological factors associated with the developmental defects of the enamel (DDE). Materials and Methods: A total of 2,500 children from 10 urban and 10 rural schools were examined using modified DDE criteria for recording enamel defects. Ten index permanent teeth were screened for the DDE. Results: The overall prevalence of the DDE was found to be 32% and the prevalence is higher in urban schools (34.3%) compared to rural schools (29.6%). The most common tooth affected by the defect was maxillary right lateral incisor (P = 28.6%) and the tooth least affected was maxillary right first premolar (P = 3%). The most common deformity was demarcated opacities (P = 28.76%) and the least common deformity was combination of diffuse opacities and hypoplasia and combination of demarcated, diffuse opacities, and hypoplasia (P = 0%). There was a very high significant association between DDE and the mothers’ pregnancy age, illness during pregnancy for mother, medication taken during pregnancy by mother, prematurity of birth, intubation done during prematurity, birth weight, systemic illness during the first 5 years of life, intake of drugs or chemicals during the first 5 years of life, nutritional status, and trauma or infection on deciduous teeth and dental caries. Conclusions: The study population showed a prevalence of 32% and very high significant association between perinatal, natal, and postnatal etiological factors. It indicates the need for educating the population about the risk factors for the DDE. PMID:27011929

    This study represents an attempt to determine the prevalence of exercise-induced bronchospasm among soccer player children. A total of 234 soccer player boys of all soccer schools from Shahr-Rey enrolled in this study. They did not have any history of a recent or chronic respiratory tract disease, a history of allergic diseases, and history of bronchodilator drugs consumption during the 24 hours prior to the study. Pulmonary function test (PFT) was performed for each participant before exercise and 6 and 15 minutes after playing soccer. The diagnosis of EIB was by a decrease in forced expiratory volume in 1 second (FEV1) by at least 10% and in peak expiratory flow rate (PEFR) by at least 15% with exercise challenge. If there was reduction in one parameter alone, the participants were considered as prone to EIB. Considering both FEV1 and PEFR the prevalence of EIB was 2.1% and 18.4% were prone to EIB. If FEV1 or PEFR tests were used as criteria for diagnosis of airway obstruction, the prevalence of EIB would be 6% and 15.8%, respectively. There was no significant difference between the post of players, family history of allergic disease and EIB in soccer players. This study suggests that at least 2.1% of soccer players will develop bronchospasm even if they do not have any history of asthma and allergy.

    Objective This study examined the prevalence of impaired fasting glucose (IFG) and diabetes and their associated factors in 17,184 Chinese hypertensive adults aged 45–75 years. Methods A cross-sectional investigation was carried out in a rural area of Lianyungang, China. Previously undiagnosed diabetes [fasting plasma glucose (FPG) ≥7.0mmol/l] and IFG (6.1–6.9mmol/l) were defined based on FPG concentration. Previously diagnosed diabetes was determined on the basis of self-report. Total diabetes included both previously diagnosed diabetes and previously undiagnosed diabetes. Results The prevalence of previously diagnosed diabetes, undiagnosed diabetes, and IFG were 3.4%, 9.8%, and 14.1%, respectively. About 74.2% of the participants with diabetes had not previously been diagnosed. In the multivariable logistic-regression model, older age, men, antihypertensive treatment, obesity (BMI ≥25kg/m2), abdominal obesity (waist circumference ≥90cm for men and ≥80cm for women), non-current smoking, a family history of diabetes, higher heart rate, lower physical activity levels, and inland residence (versus coastal) were significantly associated with both total diabetes and previously undiagnosed diabetes. Furthermore, methylene- tetrahydrofolate reductase (MTHFR) 677 TT genotype was an independent associated factor for total diabetes, and current alcohol drinking was an independent associated factor for previously undiagnosed diabetes. At the same time, older age, men, abdominal obesity, non-current smoking, current alcohol drinking, a family history of diabetes, higher heart rate, and inland residence (versus coastal) were important independent associated factors for IFG. Conclusion In conclusion, we found a high prevalence of diabetes in Chinese hypertensive adults. Furthermore, about three out of every four diabetic adults were undiagnosed. Our results suggest that population-level measures aimed at the prevention, identification (even if only based on the FPG

    Purpose: To investigate the prevalence of spina bifida occulta (SBO) and its relationship with the presence of overactive bladder (OAB) in middle-aged and elderly people in China. Methods: A cross-sectional community-based survey was carried out at 7 communities in Zhengzhou City, China from December 15, 2013 to June 10, 2014, where residents aged over 40 years were randomly selected to participate. All of the participants underwent lumbosacral radiographic analysis and relevant laboratory tests. A questionnaire including basic information, past medical history and present illness, and the OAB symptom score was filled out by all participants. Chi-square tests and logistic regression were used for data analysis with a P-value of <0.05 denoting statistical significance. Results: A total of 1,061 subjects were qualified for the final statistical analysis (58.8±11.7 years; male, 471 [44.4%]; female, 590 [55.6%]). The overall prevalence of SBO was 15.1% (160 of 1,061): 18.3% (86 of 471) in men and 12.5% (74 of 590) in women. Among these subjects, 13.7% (145 of 1,061) had OAB: 13.2% (62 of 471) in men and 14.1% (83 of 590) in women. The results of logistic regression showed that age, SBO, history of cerebral infarction (HCI), and constipation were risk factors for OAB (P<0.05), while sex, history of childhood enuresis (HCE), body mass index (BMI), and diabetes mellitus (DM) were not (P>0.05). In men, age, SBO, and constipation were risk factors for OAB (P<0.05), while HCE, BMI, DM, HCI, and benign prostate hyperplasia were not (P>0.05). In women, age, SBO, and HCI were risk factors for OAB (P<0.05), while HCE, BMI, DM, vaginal delivery, and constipation were not (P>0.05). Conclusions: The prevalence of SBO is high and it is related to OAB in middle-aged and elderly people in China. PMID:27377948

    Salmonella is frequently found in poultry and represent an important source for human gastrointestinal infections worldwide. The aim of this study was to investigate the prevalence, genotypes and antimicrobial resistance of Salmonella serotypes in broilers from Ecuador. Caeca content from 388 at random selected broiler batches were collected in 6 slaughterhouses during 1 year and analyzed by the ISO 6579/Amd1 protocol for the isolation for Salmonella. Isolates were serotyped and genotypic variation was acceded by pulsed field gel electrophoresis. MIC values for sulfamethoxazole, gentamicin, ciprofloxacin, ampicillin, cefotaxime, ceftazidime, tetracycline, streptomycin, trimethropim, chloramphenicol, colistin, florfenicol, kanamycin and nalidixic acid were obtained. Presence of blaCTX-M, blaTEM, blaSHV and blaCMY; and mcr-1 plasmid genes was investigated in resistant strains to cefotaxime and colistin respectively. Prevalence at batch level was 16.0%. The most common serotype was S. Infantis (83.9%) followed by S. Enteritidis (14.5%) and S. Corvallis (1.6%). The pulsed field gel electrophoresis analysis showed that S. Corvallis, S. Enteritidis and S. Infantis isolates belonged to 1, 2 and 12 genotypes respectively. S. Infantis isolates showed high resistance rates to 12 antibiotics ranging from 57.7% (kanamycin) up to 98.1% (nalidixic acid and sulfamethoxazole). All S. Enteritidis isolates showed resistance to colistin. High multiresistant patterns were found for all the serotypes. The blaCTX-M gene was present in 33 S. Infantis isolates while mcr-1 was negative in 10 colistin resistant isolates. This study provides the first set of scientific data on prevalence and multidrug-resistant Salmonella coming from commercial poultry in Ecuador. PMID:27414038

    Each year, an increasing number of children are born through surrogacy and thus lack a genetic and/or gestational link with their mother. This study examined the impact of surrogacy on mother-child relationships and children’s psychological adjustment. Assessments of maternal positivity, maternal negativity, mother-child interaction and child adjustment were administered to 32 surrogacy, 32 egg donation and 54 natural conception families with a 7-year-old child. No differences were found for maternal negativity, maternal positivity or child adjustment, although the surrogacy and egg donation families showed less positive mother-child interaction than the natural conception families. The findings suggest that both surrogacy and egg donation families function well in the early school years. PMID:21895360

    Frailty has been previously studied in Western countries and the urban Korean population; however, the burden of frailty and geriatric conditions in the aging populations of rural Korean communities had not yet been determined. Thus, we established a population-based prospective study of adults aged ≥ 65 years residing in rural communities of Korea between October 2014 and December 2014. All participants underwent comprehensive geriatric assessment that encompassed the assessment of cognitive and physical function, depression, nutrition, and body composition using bioimpedance analysis. We determined the prevalence of frailty based on the Cardiovascular Health Study (CHS) and Korean version of FRAIL (K-FRAIL) criteria, as well as geriatric conditions. We recruited 382 adults (98% of eligible adults; mean age: 74 years; 56% women). Generally, sociodemographic characteristics were similar to those of the general rural Korean population. Common geriatric conditions included instrumental activity of daily living disability (39%), malnutrition risk (38%), cognitive dysfunction (33%), multimorbidity (32%), and sarcopenia (28%), while dismobility (8%), incontinence (8%), and polypharmacy (3%) were less common conditions. While more individuals were classified as frail according to the K-FRAIL criteria (27%) than the CHS criteria (17%), the CHS criteria were more strongly associated with prevalent geriatric conditions. Older Koreans living in rural communities have a significant burden of frailty and geriatric conditions that increase the risk of functional decline, poor quality of life, and mortality. The current study provides a basis to guide public health professionals and policy-makers in prioritizing certain areas of care and designing effective public health interventions to promote healthy aging of this vulnerable population.

    We aimed to describe Pneumocystis jirovecii pneumonia (PCP) prevalence and features in children from sub-Saharan Africa and to investigate PCP-associated risk factors. During 2006-2007 we used molecular methods to test children younger than 5 years old admitted with severe pneumonia to a hospital in southern Mozambique for Pneumocystis infection. We recruited 834 children. PCP prevalence was 6.8% and HIV prevalence was 25.7%. The in-hospital and delayed mortality were significantly higher among children with PCP (20.8% vs. 10.2%, p 0.021, and 11.5% vs. 3.6%, p 0.044, respectively). Clinical features were mostly overlapping between the two groups. Independent risk factors for PCP were age less than a year (odds ratio (OR) 6.34, 95% confidence interval (CI) 1.86-21.65), HIV infection (OR 2.99, 95% CI 1.16-7.70), grunting (OR 2.64, 95% CI 1.04-6.73) and digital clubbing (OR 10.75, 95% CI 1.21-95.56). PCP is a common and life-threatening cause of severe pneumonia in Mozambican children. Mother-to-child HIV transmission prevention should be strengthened. Better diagnostic tools are needed.

    Ovine models are used to study intervertebral disc (IVD) degeneration. The objective of the current study was to assess the naturally occurring age-related changes of the IVD that can be diagnosed by CT and MRI in the lumbar spine of sheep. We used CT and T2-weighted MR images to score the IVD (L6S1 to L1L2) in 41 sheep (age, 6 mo to 11 y) that were euthanized for reasons not related to musculoskeletal disease. T2 mapping and measurement of T2 time of L6S1 to L2L3 were performed in 22 of the sheep. Degenerative changes manifested as early as 2 y of age and occurred at every IVD level. Discs were more severely damaged in older sheep. The age effect of the L6S1 IVD was larger than the average age effect for the other IVD. The current study provides evidence that lesions similar to those encountered in humans can be identified by CT and MRI in lumbar spine of sheep. Ideally, research animals should be assessed at the initiation of preclinical trials to determine the extent of prevalent degenerative changes. The ovine lumbosacral disc seems particularly prone to degeneration and might be a favorable anatomic site for studying IVD degeneration. PMID:27538861

    Essentials Evidence for the simplified Wells rule in ruling out acute pulmonary embolism (PE) is scarce. This was a post-hoc analysis on data from 6 studies comprising 7268 patients with suspected PE. The simplified Wells rule combined with age-adjusted D-dimer testing may safely rule out PE. Given its ease of use, the simplified Wells rule is to be preferred over the original Wells rule.

    Several approaches were made by actuaries and demographers to correct and smooth the Indian age distribution with special emphasis on population in age group 0-4 at different points of time. The present analysis conceives the life table stationary population (using the West Model) as 'reference standard'. 2 parameters were estimated from a regression equation using the proportion of population in age groups 5-14 and 60-plus as independent variables and that in 0-4 as the dependent variable. The corrected census proportions in age group 0-4 obtained from the regression model under certain assumptions for the 14 major states and India seem to be consistent and to have slightly lower values than those of the 1971 adjusted data. Moreover, unadjusted and adjusted proportions in 5-14 and 60 plus do not show any significant difference between the predicted values. Using the corrected population aged 0-4 years, the average annual birth and death rates during the 5 year period preceeding the 1981 census have been estimated for those 14 states and India as well. The estimated birth rates so obtained were further adjusted using an appropriate factor from the West Model and Indian life table survival ratios. The final estimates seem to be consistent, except for a few, and to have slightly higher values than those of earlier estimates. As the present analysis is based on a 5% sample and confined to only 14 states, it is proposed to study the same for all the states and India in greater detail using full count data on age distribution and actul life tables as and when available.

    ABSTRACT This study estimated the prevalence of anaemia and associated factors in a probability sample of 993 children aged 6-59 months in Cape Verde, West Africa. Odds ratio (OR) and 95% confidence interval (95% CI) were estimated from a hierarchical model for multiple analysis to assess the association between anaemia and explanatory variables. The prevalence of anaemia was 51.8% (95% CI 47.7-55.8). Children who resided within poor household conditions (OR 1.99; 95% CI 1.06-3.71) were below 24 months of age (OR 3.23; 95% CI 2.03-5.15) and recently experienced diarrhoea (OR 1.58; 95% CI 0.99-2.50) were at high risk of anaemia. Anaemia should be considered a serious public-health concern in Cape Verde, mainly for children below 24 months. Further, special consideration should be given to children who have experienced recent diarrhoea and belong to families residing in poor household conditions. PMID:25895198

    The objective of this multicenter descriptive study was to calculate the frequency of genital warts among Turkish women aged 15-49 years, who visited outpatient gynecology clinics for a variety of reasons. The study was conducted in February 2011 to collect data for a minimum of 154 patients at each center, and the total sample size reached 2,967 women (95.1% completion rate). Oral informed consents were obtained. A questionnaire including data on socio-demographic characteristics and reasons for admission was administered, and a pelvic examination was performed. The overall point prevalence was 35% (95% CI = 3.1%-4.0%), correcting for sampling design, with the highest rates observed in the 15 to 19-year-old group. The odds of having a genital wart was 1.82 times (95% CI = 0.99-3.33) higher among non-pregnant participants than in pregnant women (p = 0.051). The overall point prevalence of genital warts among reproductive-aged women attending gynecology outpatient clinics for any reason in Turkey was 35%.

    Introduction Skin lesions may be of dermatological importance, affect appearance, and cause problems communicating with peers and may be especially more significant in childhood. Aim Information on the prevalence of pediatric dermatoses in Western Turkey. This study was aimed to define the existing data. Material and methods A cross-sectional study was conducted in Canakkale, Turkey, in September-December 2013. It involved 1,957 students from five randomly selected primary and secondary schools. Each student was interviewed for age, gender, and family history, and a dermatologic examination was performed by a dermatologist. Data were coded and analyzed. Results Of the students, 79.9% revealed at least one dermatosis. The most common disease was benign neoplasms (76%), followed by pigmentary disorders (26.8%), and xerosis (5.8%). In primary schools, the acquired melanocytic nevus, hypopigmented macule, and xerosis; in secondary school the acne was statistically significantly more common. Acne and xerosis was more common in girls, and pityriasis alba was statistically more common in boys. Students who had at least one dermatosis were positively correlated with monthly income. Conclusions In Turkish school age children, the prevalence of dermatosis is 79.9%. It may be due to not using preventive means for adequate protection from the sun and other environmental factors. Infectious dermatosis and atopic dermatitis are rare and it may depend on the adequacy of public health work. PMID:27512351

    The aim of this study is to assess the factors associated with hypertension prevalence, awareness, treatment, and control, in the elderly populations of the International Mobility in Aging Study (IMIAS). Approximately 200 men and 200 women aged 65-74 years were recruited at each site (n=1995) during IMIAS' 2012 baseline survey at five cities: Kingston (Canada), Saint-Hyacinthe (Canada), Tirana (Albania), Manizales (Colombia) and Natal (Brazil). Blood pressure and anthropometric measurements were taken at participants' homes. Hypertension prevalence ranged from 53.4% in Saint-Hyacinthe to 83.5% in Tirana. Diabetes and obesity were identified as risk factors in all cities. More than two-thirds of hypertensive participants were aware of their condition (from 67.3% in Saint-Hyacinthe to 85.4% in Tirana); women were more aware than men. Awareness was positively associated with diabetes in Kingston, Manizales and Natal. Though most of those aware of their hypertensive condition were being treated pharmacologically, associations between awareness and physical activity and refraining from smoking were weak. Control among treated hypertensive participants was low, especially in Tirana and Natal. Diabetes and physical inactivity were associated with poor hypertension control. Hypertension is common in the older populations of IMIAS. Diabetes is strongly associated with hypertension prevalence, awareness and lack of control of hypertension. The fact that awareness is not strongly associated with healthy behaviours suggests that antihypertensive medication is not accompanied by non-pharmacological therapies. Improved health behaviours could strengthen hypertension control. Efforts should be made to increase men's awareness of hypertension. Hypertension control in diabetic patients is a challenge.

    Individuals with obsessive-compulsive disorder (OCD) experience recurrent obsessive and/or compulsive thoughts and behaviours which cause them distress, and significantly impair their daily lives. The disorder is thought to have a chronic course and a low rate of remission, as evidenced by mainly clinical samples. Longitudinal psychiatric epidemiological studies are few and far between. This article presents the findings relating to OCD from one such study, the Zurich Study: OCD defined according to DSM-5 criteria had a high prevalence rate and frequently a chronic course but it had a long-term remission rate of almost 60%, which is higher than hitherto believed. OCD was generally highly comorbid with other disorders and particularly closely associated with social phobia.

    We studied the prevalence of arterial hypertension and its associated risk factors in the urban population of León, State of Guanajuato. Using a cross sectional design we selected by home interview 1000 volunteers 16 to 70 years old from three socioeconomic levels. Forty seven of 468 males (10.0%) and 67 of 532 females (12.6%) were found with hypertension. Increased rates for women were significant (p < 0.01). The rates of hypertension increased slowly with age for men, but for women a sudden increase was found at 48 years of age, the mean age of menopause. At 50 years of age or older, the rate for hypertension was 22.3% for men and 41.7% for women (chi 2 = 7.27, p = 0.007). The multivariate study of factors associated with hypertension showed significance for age, body mass index and smoking habit for the total group and for men, but only age and body weight for women. No association was seen for alcoholism, life style and socioeconomy. A univariate analysis of menopause was strongly associated with hypertension (chi 2 = 46.8, p < 0.0001) and the relative risk for hypertension in menopausal women was 8.04 (7.56-9.73). We conclude that the frequency of hypertension in this urban population is similar to that found in other studies except for women over 50 years of age. Such excess risk of hypertension in this group may be explained by an increased frequency of obesity and an increment in sedentary habits which occur in our female population, and the possible participation of hormone deprivation.

    Background The prevalence of maternal obesity at the beginning of pregnancy is increasing. However, there are some studies reporting the stabilisation of obesity epidemic or even the downward trend in the general population. Objective To determine the prevalence of overweight and obesity in Lithuanian pre-pregnant women during 3 decades. Methods This observational retrospective study included a sample of 2827, women aged 18–44 years who gave birth in 1987–1989, 1996–1997 and 2007–2010: 861 (30.5%), 995 (35.2%) and 971 (34.3%), respectively. All women were divided into groups by body mass index (BMI) calculated from self-reported weight and height, and age reported during the first antenatal visit. Quantitative parametric variables were expressed as mean and SD; qualitative variables, as absolute numbers (n) and percentage (%). For parametric data, analysis of variance (ANOVA) was used. Differences were considered statistically significant at p<0.05. Results The prevalence of overweight and obesity among women aged 18–24 years decreased from 20.9% in 1987–1989 to 9.5% in 1996–1997 but increased to 15.7% in 2007–2010; among women aged 25–34 years, decreased from 35.5% in 1987–1989 to 23% in 1996–1997 and to 22.4% in 2007–2010; and among women aged 35–44 years decreased from 64.9% in 1987–1989 to 34% in 1996–1997 but increased to 45.3% in 2007–2010. BMI increased with an increasing age (r=0.254, p<0.05). Analysis by separate periods (1987–1989, 1996–1997 and 2007–2010) revealed a positive correlation between BMI and age at the first antenatal visit in all periods (r=0.325, p<0.01; r=0.266, p<0.01; and r=0.210, p<0.01, respectively). Conclusions The prevalence of overweight and obesity among pre-pregnant women tended to decrease in the Lithuanian urban area during 3 decades. A slight increase in overweight and obesity documented in 2007–2010 compared with 1996–1997 most likely was caused by older maternal age. PMID

    A cross-sectional study was carried out on Bahraini preschoolers aged 2-5 years (354 males and 344 females) to determine the prevalence of overweight and obesity using the World Health Organization and the International Obesity Task Force cut-off values. Weight and height were recorded and body mass index (BMI) was calculated to determine the proportion of overweight and obesity. Using the World Health Organization percentile cut-off values, overweight (12.3%) and obesity (8.4%) was higher in females between 2 and <4 years of age whereas, the proportion of both overweight (8.4%) and obesity (7.2%) were higher in males between 4 and <6 years of age. Relative to the International Obesity Task Force indicators, the World Health Organization cut-off values produced nearly a 2-fold increase in both overweight and obesity at most ages. It is therefore important to ensure that the same cut-off reference values are used to define overweight and obesity particularly in preschoolers. Shifting to the new World Health Organization child growth standards may have important implications for child health programmes.

    Hepatitis C virus (HCV) infection is a public health issue worldwide. Injecting drug use remains the major mode of transmission in developed countries. Monitoring the HCV transmission dynamic over time is crucial, especially to assess the effect of harm reduction measures in drug users (DU). Our objective was to estimate the prevalence and incidence of HCV infection in DU in France using data from a repeated cross-sectional survey conducted in 2004 and 2011. Age- and time-dependent HCV prevalence was estimated through logistic regression models adjusted for HIV serostatus or injecting practices. HCV incidence was estimated from a mathematical model linking prevalence and incidence. HCV prevalence decreased from 58·2% [95% confidence interval (CI) 49·7-66·8] in 2004 to 43·2% (95% CI 38·8-47·7) in 2011. HCV incidence decreased from 7·9/100 person-years (95% CI 6·4-9·4) in 2004 to 4·4/100 person-years (95% CI 3·3-5·9) in 2011. HCV prevalence and incidence were significantly associated with age, calendar time, HIV serostatus and injecting practices. In 2011, the highest estimated incidence was in active injecting DU (11·2/100 person-years). Given the forthcoming objective of generalizing access to new direct antiviral agents for HCV infection, our results contribute to decision-making and policy development regarding treatment scale-up and disease prevention in the DU population.

    Transition from genetic risk to the development of systemic autoimmunity associated with rheumatoid arthritis (RA) is considered a key step for the development of RA and often referred to as the immune onset of the disease. The aim of this study is to identify predictors for the presence of anticitrullinated protein antibodies (ACPA) as a marker of systemic autoimmunity associated with RA in a high-risk population, an ongoing cohort of first-degree relatives of patients with RA. We assessed the presence of ACPA in individuals without clinical evidence of RA. We examined characteristics associated with ACPA positivity using general estimation equations to account for multiple observations per individual. A total of 1159 serum samples from 1025 subjects were analyzed, 69 samples (6%) were ACPA-positive, and 227 (20%) positive for rheumatoid factor. Participants had a median age of 45 years (interquartile range (IQR): 33-55) at baseline and 76% were women. Overall, ACPA positivity increased with age (p < 0.001). Among women, ACPA positivity was particularly associated with the age group 45 to 55 years (p = 0.003), but not among men (p = 0.7). In multivariable adjusted analyses, age older than 45, female sex and tobacco smoking were independently associated with ACPA positivity. In our cohort, the presence of ACPA was associated with older age and peaked in women around age 45 to 55 years, the perimenopausal period, suggesting that the development of ACPA may be favored by the decline in ovarian function.

    Objective: There is a link between joint and gut inflammation of unknown etiology in arthritis. Existing research indicates that regular consumption of high-fructose corn syrup sweetened (HFCS) soft drinks, but not diet soft drinks, may be associated with increased risk of seropositive rheumatoid arthritis (RA) in women, independent of other dietary and lifestyle factors. One unexplored hypothesis for this association is that fructose malabsorption, due to regular consumption of excess free fructose (EFF) and HFCS, contributes to fructose reactivity in the gastrointestinal tract and intestinal in situ formation of enFruAGEs, which once absorbed, travel beyond the intestinal boundaries to other tissues and promote inflammation. In separate studies, the accumulation of advanced glycation end-products has been associated with joint inflammation in RA. Objective of this study was to assess the association between EFF beverages intake and non-age, non-wear and tear-associated arthritis in US young adults. Methods: In this cross sectional study of 1209 adults aged 20–30y, (Nutrition and Health Examination Surveys 2003–2006) exposure variables were high EFF beverages, including HFCS sweetened soft drinks, and any combination of HFCS sweetened soft drinks, fruit drinks (FD) and apple juice, referred to as tEFF. Analyses of diet soda and diet FD were included for comparison. The outcome was self-reported arthritis. Rao Scott Ҳ2 was used for prevalence differences and logistic regression for associations, adjusted for confounders. Results: Young adults consuming any combination of high EFF beverages (tEFF) ⩾5 times/week (but not diet soda) were three times as likely to have arthritis as non/low consumers (odds ratios=3.01; p⩽0.021; 95% confidence intervals=1.20–7.59), independent of all covariates, including physical activity, other dietary factors, blood glucose and smoking. Conclusion: EFF beverage intake is significantly associated with arthritis in US adults

    Following the 2008 Wenchuan earthquake, the Chinese government instituted an infant and young and child nutrition program that included promotion of in-home fortification of complementary food with ying yang bao (YYB), a soy-based powder containing iron, 2.5 mg as iron-EDTA and 5 mg as ferrous fumarate, and other micronutrients. Ying yang bao was provided to participating families in 8 poor rural counties in Sichuan, Shaanxi, and Gansu provinces by the Ministry of Health. We assessed hemoglobin levels among infants and young children (IYC) aged 6 to 23 months at baseline in May 2010 (n = 1290) and during follow-up in November 2010 (n = 1142), May 2011 (n = 1118), and November 2011 (n = 1040), using the Hemocue method. Interviewers collected basic demographic information and child feeding practices from the children's caretakers. Altitude-adjusted hemoglobin level averaged 10.8 g/dL, and total anemia prevalence was 49.5% at baseline. Average hemoglobin was 11.3 g/dL at 6 months, 11.6 g/dL at 12 months, and 11.7 g/dL at 18 months after introduction of YYB. Moderate anemia (hemoglobin: 70-99 g/dL) decreased from 20.3% at baseline to 7.5%, 5.8%, and 7.3% after 6, 12, and 18 months of home fortification, respectively (P < .001), whereas mild anemia (hemoglobin: 100-110 g/dL) decreased from 29.0% to 16.7%, 18.1%, and 15.4%, respectively (P < .001). Among infants aged 6 to 23 months, 95% had regularly been fed YYB during the observation period. Regression analysis showed that the duration of YYB consumption and number of sachets consumed per week correlated positively with hemoglobin levels and negatively with anemia rates. Home food fortification with YYB is feasible and effective for nutrition promotion among IYC in high-risk regions of China.

    In 2011, Chile experienced an increase in the number of cases of IMD caused by Neisseria meningitidis group W. This epidemiological scenario prompted authorities to implement prevention strategies. As part of these strategies, the Institute of Public Heath of Chile conducted a cross-sectional study to determine the prevalence of pharyngeal carriage of N. meningitidis in a representative sample of healthy children and adolescents aged 10-19 years. The identification of presumptive N. meningitidis strains was performed by testing carbohydrate utilization in the National Reference Laboratory at the ISP. Association of meningococcal carriage with risk factors was analyzed by calculating the Odds Ratio. Selected variables were included in a logistic model for risk analyses. The prevalence of carriage of N. meningitidis was 6.5% (CI: 5.7-7.3%). Older age (carriers: 14.2±0.29 vs. non-carriers: 13.8±0.08 years old; p=0.009), cohabitation with children (carriers: 0.9±0.13 vs. non-carriers: 0.7±0.03; p=0.028), number of smoking cohabitants (carriers: 0.55±0.13 vs. non-carriers: 0.44±0.03) and frequent attendance to crowded social venues (carriers: 49% vs. non-carriers: 37%; p=0.008) were determined to favor carriage. Statistical modeling showed that meningococcal carriage was associated with older age (OR: 1.077, p-value: 0.002) and cohabitation with children (OR: 1.182, p-value: 0.02).

    Botswana imports most pig-based products from neighbouring countries. Pig farming is limited by, among other things, the negative effect of parasites and diseases on production. The object of this study was to determine the prevalence of ecto- and endoparasites in pigs of different ages and sexes in the Southeast District of Botswana. Thirty-nine pigs were sampled for endoparasites and 19 for ectoparasites during a period of 2 1/2 months. Of all the pigs sampled, 54,55% were infected with Ascaris suum, 20,45% with Trichostrongylus spp. and 6,82% with Trichuris suis. Ascaris suum was found to be the most common endoparasite infesting both mature, i.e. 12 months and older, and young, i.e. less than 12 months old, pigs. Although not significantly different (P > 0,05), the prevalence of this parasite species was slightly higher (68,42% with an average of 1,023 +/- 545 eggs per gram (EPG) of faeces per pig) in mature than in young pigs (55% with an of average 1,500 +/- 846 EPG of faeces per pig). The prevalence of Trichostrongylus spp. was lower in mature (5,26% with 20 +/- 14 EPG of faeces per pig) than in young pigs (25% with 22 +/- 9 EPG of faeces per pig). The prevalence of T. suis was also lower in mature (0% infection) than in young pigs (15% with 9 +/- 4 EPG of faeces per pig). The prevalence of the three endoparasite species was not significantly different between the sexes A. suum (1,020 +/- 883 v. 1,503 +/- 522 EPG of faeces per pig), Trichostrongylus spp. (24 +/- 14 v. 18 +/- 8 EPG of faeces per pig) and T. suis (11 +/- 6 v. 2 +/- 4 EPG of faeces per pig) for male and female pigs respectively. Sarcoptes scabiei was the only ectoparasite identified on the pigs sampled for external parasites. It infested 40% of all pigs but the infestation on young pigs (70%) was higher than on the mature ones (33,33%). Since the infection of internal and external parasites was similar in young and old pigs of both sexes, controlling parasites is of great importance since these

    Background: The incidence of superior labral surgery has increased in the past decade in the United States, and a contributing factor could be an increased rate of superior labral tears diagnosed with magnetic resonance imaging (MRI). Prior MRI studies of the asymptomatic shoulder have focused on rotator cuff pathology or pathology in a narrow and specific group of athletes. Labral abnormalities have not previously been thoroughly evaluated in asymptomatic middle-aged individuals. Purpose: To evaluate the prevalence of superior labral tears diagnosed by MRI in the asymptomatic shoulders of middle-aged people (age range, 45-60 years). Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 53 asymptomatic adults (age range, 45-60 years) with no history of surgery or injury to either shoulder were included in the study. Physical examinations of all shoulders were performed. Noncontrast MRI (1.5 T) was performed in 1 randomly determined shoulder of each subject. Two fellowship-trained musculoskeletal radiologists who were blinded to the purpose of the study and ages of the subjects evaluated each MRI. Results: Radiologists interpreted the MRIs as consistent with superior labral tears in 55% and 72% of the cohort. Comparison of the radiological evaluations of the superior labra were moderate (κ = 0.410, P = .033). There were no differences in readings for superior labral tear regarding age (P = .87), sex (P = .41), whether the dominant shoulder underwent MRI (P = .99), whether the subject worked a physical job (P = .08), or whether the subject participated in overhead sports for a period of 1 year (P = .62). Conclusion: Superior labral tears are diagnosed with high frequency using MRI in 45- to 60-year-old individuals with asymptomatic shoulders. These shoulder MRI findings in middle-aged populations emphasize the need for supporting clinical judgment when making treatment decisions for this patient population. Clinical Relevance: To avoid

    Rey's Auditory Verbal Learning Test (AVLT) is widely used to evaluate dysfunctional episodic memory. The current study aimed to provide extended age- and gender-specific norms for the German AVLT for individuals older than 50 years. In 690 subjects, a comprehensive medical examination including a structural 3.0-tesla magnetic resonance imaging scan was administered, as well as extensive neuropsychological tests. After controlling for exclusion criteria, 407 subjects were included in the analysis. AVLT performance decreased with age, and women outperformed men. We present age- and gender-specific normative data for the German AVLT from subjects aged between 50 and 70 years.

    Partial secondary adentia together with caries and parodont diseases is among the most widespread diseases of dentofacial system, correlated, in addition, to the number of lost teeth, with the age. Result in speech and chewing functions' disorders, change of face shape, esthetic and psychosocial inferiority, pathologies of digestive and other systems, formation of the chronic infection areas, changes of reactivity etc,. Improvement of the methods of prevention and treatment of the above diseases is one of the most significant problems in the dentistry. Effectiveness of dental assistance organization and planning is based on the epidemiological studies. In Georgia, epidemiological studies were conducted in the populations of various age groups in previous years though, according to our data, no studies of dentition defects and deformations were conducted in the recent decades. Goal of our research was study of prevalence and severity of dentition defects and deformations, regarding sizes of existing defects, their localization, causes and types of deformation in different age groups, for development of specialized dentistry assistance plans and prevention programs. We have studied 147 patients of ages between 15 and 40 years. We have developed special questionnaire. Researches showed that in the studied age group (15-40), 62% (96 patients), i.e. more than half of studied 147 patients had secondary adentia. Most of them had the defects in the buccal teeth area. 112 of studied 147 patients required orthopedic treatment but only 18 (16%) of them have visited the clinic for this purpose while 94 (83.9%) of them were unaware about need of prothetic assistance. Regarding significance of the mentioned problem, the obtained results show the need of timely orthopedic intervention for the purpose of prevention of further complications. As a result, a specialized dental assistance plan and prevention measures' program has been developed to prevent further complications.

    In 2008, we published epidemiological data from 1972 to 2005 that suggested an increase in insomnia-related symptoms among the working-age population. The results were based on the National FINRISK (FR) Study samples of the Finnish adult population aged 25-64, and on the Finnish Quality of Work Life Surveys (FQWLS), carried out among Finnish salary earners. Both of these ongoing studies have since provided two new estimates of insomnia-related symptoms. Chronic insomnia-related symptoms were 9.0% (95% CI 8.3-9.7), 9.6% (95% CI 8.8-10.4) in FR 2007 and 2012, respectively; and 9.1% (95% CI 8.3-10.0), 9.2% (95% CI 8.4-10.1) in FQWLS 2008 and 2013, respectively. Occasional insomnia-related symptoms were 45.3% (95% CI 44.1-46.6), 42.5% (95% CI 41.1-43.9) in FR 2007 and 2012, respectively; and 40.3% (95% CI 38.8-41.7), 44.8% (95% CI 41.1-43.9) in FQWLS 2008 and 2013, respectively. The new estimates further strengthen the interpretation of the ongoing increase in occasional insomnia-related symptoms among the Finnish general adult population. The increase in occasional symptoms was most prominent among employees. However, chronic insomnia symptoms showed no further increase.

    Previous study revealed that 8%-12% adolescents suffered from various types of anxiety disorders, and which had interfered with adolescent daily life function and affected adolescent social function. The aim of this study was to evaluate anxiety status and its related factors among students aged 13-26 years from Wuhu, China. This was a cross-sectional observational study. A sample of school students who come from a university, four high schools and four middle schools in Wuhu city were recruited, Self-Rating Anxiety Scale (SAS) was used to measure the anxiety status among students aged 13-26 years, and some demographic characteristics of students also was determined. A total of 5249 students were included in our study. The overall rate of anxiety status among students was 14.1%. A significant difference was observed between anxiety status and sex, mothers education level, dietary and siesta habit (P < 0.05), only-child family, gentle temper, regular breakfast habit, friend support was associated with lower scores on anxiety status. The findings indicated that anxiety status is common among school students. Preventive and treatment strategies are highly recommended. PMID:25550963

    To evaluate the epidemiological significance of HEp-2 cell-adherent Escherichia coli isolates in diarrheal disease, we performed a study with 513 Venezuelan infants with diarrhea and 241 age-matched controls to determine the prevalence of enteropathogenic E. coli (enteroadherent E. coli, enterotoxigenic E. coli, enteroinvasive E. coli, and enterohemorrhagic E. coli) and their correlation with O:H serotypes. E. coli isolates exhibiting localized and aggregative adherence in the HEp-2 cell assay were significantly more frequently isolated from the patients (8.5 and 26.9%, respectively) than from the controls (1.7 and 15%, respectively). This difference was significant for the group 0 to 2 months of age but for older infants. Regardless of age, E. coli isolates with diffuse adherence were found at similar frequencies in both the patients and the controls. A striking correlation between classic O serogroups and localized adherence was also observed. These findings confirm the pathogenic role of E. coli with localized and aggregative adherence in diarrheal disease, as well as the epidemiological importance of O:H serotyping for characterizing localized-adhering E. coli.

    Misreporting of dates and ages poses serious difficulties for the estimation of the age distribution and birth and death rates in many developing countries. The pervasiveness of these problems is illustrated with data from a well-designed on-going survey in Pakistan, the Pakistan Demographic Survey. Methods for reconciling discrepancies, based on the assumptions of constant misreporting and survivorship patterns, are presented. The reasoning behind these methods could be applied much more generally. Research into the cultural interpretations of age and dates, and the nature of possible biases, is called for.

    Objective Unplanned pregnancy in women with SLE can have grave complications both for the child and the woman. We studied the prevalence of contraceptive counseling among women of reproductive age with SLE at a university hospital in Northeast Thailand. Methods Recruited: 125 women with SLE, between 15 and 50 years, followed up at the Rheumatology Clinic. A questionnaire was administered and the results analyzed to identify the prevalence of contraceptive counseling. Results The majority of women with SLE had had their reproductive goals evaluated (76.00%, 95% CI 66–83) and received contraceptive counseling (72%). Among the SLE patients at risk for pregnancy, only one-third used effective contraception and one-fifth of those did not have any background knowledge about SLE and pregnancy. Contraceptive counseling was more frequently given to women who had had a previous pregnancy or who were already concerned about SLE as related to pregnancy. Conclusion The majority of SLE patients had at one time or other received contraceptive counseling, but some reported not grasping the gravity. The survey results presented herein suggest that a multidisciplinary team is needed to improve patient knowledge regarding SLE as it affects on pregnancy and relatedly contraceptive counseling.

    Objectives: There are no nationally representative hearing loss (HL) prevalence data available for Canadian youth using direct measurements. The present study objectives were to estimate national prevalence of HL using audiometric pure-tone thresholds (0.5 to 8 kHz) and or distortion product otoacoustic emissions (DPOAEs) for children and adolescents, aged 3 to 19 years. Design: This cross-sectional population-based study presents findings from the 2012/2013 Canadian Health Measures Survey, entailing an in-person household interview and hearing measurements conducted in a mobile examination clinic. The initial study sample included 2591 participants, aged 3 to 19 years, representing 6.5 million Canadians (3.3 million males). After exclusions, subsamples consisted of 2434 participants, aged 3 to 19 years and 1879 participants, aged 6 to 19 years, with valid audiometric results. Eligible participants underwent otoscopic examination, tympanometry, DPOAE, and audiometry. HL was defined as a pure-tone average >20 dB for 6- to 18-year olds and ≥26 dB for 19-year olds, for one or more of the following: four-frequency (0.5, 1, 2, and 4 kHz) pure-tone average, high-frequency (3, 4, 6, and 8 kHz) pure-tone average, and low-frequency (0.5, 1, and 2 kHz) pure-tone average. Mild HL was defined as >20 to 40 dB (6- to 18-year olds) and ≥26 to 40 dB (19-year olds). Moderate or worse HL was defined as >40 dB (6- to 19-year olds). HL in 3- to 5-year olds (n = 555) was defined as absent DPOAEs as audiometry was not conducted. Self-reported HL was evaluated using the Health Utilities Index Mark 3 hearing questions. Results: The primary study outcome indicates that 7.7% of Canadian youth, aged 6 to 19, had any HL, for one or more pure-tone average. Four-frequency pure-tone average and high-frequency pure-tone average HL prevalence was 4.7 and 6.0%, respectively, whereas 5.8% had a low-frequency pure-tone average HL. Significantly more children/adolescents had unilateral HL

    Hurricane Katrina dramatically altered the level of social and environmental stressors for the residents of the New Orleans area. The Family Stress Model describes a process whereby felt financial strain undermines parents' mental health, the quality of family relationships, and child adjustment. Our study considered the extent to which the Family Stress Model explained toddler-aged adjustment among Hurricane Katrina affected and nonaffected families. Two groups of very low-income mothers and their 2-year-old children participated (pre-Katrina, n = 55; post-Katrina, n = 47). Consistent with the Family Stress Model, financial strain and neighborhood violence were associated with higher levels of mothers' depressed mood; depressed mood was linked to less parenting efficacy. Poor parenting efficacy was associated to more child internalizing and externalizing problems.

    The Duke Treadmill Score (DTS) is an established clinical tool for risk stratification. Our aim was to determine if other variables could improve the prognostic power of the DTS and if so, to modify the DTS nomogram. From a total of 1,959 patients referred for exercise testing at the Palo Alto VA Medical Center from 1997 to 2006 (a mean follow-up of 5.4 years), we studied 1,759 male veterans (age 57 +/- 12 years) free of heart failure. Double product (DP) was calculated by multiplying systolic blood pressure and heart rate; variables and their products were subtracted to obtain the differences between at rest and maximal exercise (reserve) and recovery. Of all the hemodynamic measurements, DP reserve was the strongest predictor of cardiovascular death (CVD) (Wald Z-score -3.84, p <0.001) after adjustment for potential confounders. When the components of DTS were entered in the Cox hazard model with DP reserve and age, only DP reserve and age were chosen (p <0.00001). Using the Cox coefficients, a score calculated by [age - DTS - 3 x (DP reserve/1,000)] yielded an area under the curve of 0.84 compared with 0.76 for the DTS. Using this equation, a nomogram was constructed by adding age and DP reserve to the original DTS nomogram improving estimation of annual CVD. In conclusion, we propose an age and DP reserve-adjusted DTS nomogram that improves the prognostic estimates of average annual CVD over the DTS alone.

    Purpose Little is known about the suitability of three commonly-used body mass index (BMI) classification system for Indigenous children. This study aims to estimate overweight and obesity prevalence among school-aged Nunavik Inuit children according to International Obesity Task Force (IOTF), Centers for Disease Control and Prevention (CDC), and World Health Organization (WHO) BMI classification systems, to measure agreement between those classification systems, and to investigate whether BMI status as defined by these classification systems is associated with levels of metabolic and inflammatory biomarkers. Methods Data were collected on 290 school-aged children (8–14 years; 50.7% girls) from the Nunavik Child Development Study (NCDS) with data collected in 2005–2010. Anthropometric parameters were measured and blood sampled. Participants were classified as normal weight, overweight and obese according to BMI classification systems. Weighted Kappa (kw) statistics assessed agreement between different BMI classification systems and multivariate analysis of variance ascertained their relationship with metabolic and inflammatory biomarkers. Results The combined prevalence rate of overweight/obesity was 26.9% (with 6.6% obesity) with IOTF, 24.1% (11.0%) with CDC, and 40.4% (12.8%) with WHO classification systems. Agreement was the highest between IOTF and CDC (kw=0.87) classifications, and substantial for IOTF and WHO (kw=0.69), and CDC and WHO (kw=0.73). Insulin and high-sensitivity C-reactive protein plasma levels were significantly higher from normal weight to obesity, regardless of classification system. Among obese subjects, higher insulin level was observed with IOTF. Conclusion Compared with other systems, IOTF classification appears to be more specific to identify overweight and obesity in Inuit children. PMID:26095406

    Female reproductive function changes during aging with the estrous cycle becoming more irregular during the transition to menopause. We found that intermittent shifts of the light-dark cycle disrupted regularity of estrous cycles in middle-aged female mice, whose estrous cycles were regular under unperturbed 24-hr light-dark cycles. Although female mice deficient in Cry1 or Cry2, the core components of the molecular circadian clock, exhibited regular estrous cycles during youth, they showed accelerated senescence characterized by irregular and unstable estrous cycles and resultant infertility in middle age. Notably, tuning the period length of the environmental light-dark cycles closely to the endogenous one inherent in the Cry-deficient females restored the regularity of the estrous cycles and, consequently, improved fertility in middle age. These results suggest that reproductive potential can be strongly influenced by age-related changes in the circadian system and normal reproductive functioning can be rescued by the manipulation of environmental timing signals.

    Background falls are a major cause of disability and death in older people. Women are more likely to fall than men, but little is known about whether risk factors for falls differ between the sexes. We used data from the English Longitudinal Study of Ageing to investigate the prevalence of falls by sex and to examine cross-sectionally sex-specific associations between a range of potential risk factors and likelihood of falling. Methods participants were 4,301 men and women aged 60 and over who had taken part in the 2012–13 survey of the English Longitudinal Study of Ageing. They provided information about sociodemographic, lifestyle and behavioural and medical factors, had their physical and cognitive function assessed and responded to a question about whether they had fallen down in the last two years. Results in multivariable logistic regression models, severe pain and diagnosis of at least one chronic disease were independently associated with falls in both sexes. Sex-specific risk factors were incontinence (odds ratio (OR), 1.48; 95% CI, 1.19, 1.85) and frailty (OR 1.69, 95% CI 1.06, 2.69) in women, and older age (OR 1.02, 95% CI 1.04, 1.07), high levels of depressive symptoms (OR 1.33, 95% CI 1.05, 1.68), and being unable to perform a standing balance test (OR 3.32, 95% CI 2.09, 5.29) in men. Conclusion although we found some homogeneity between the sexes in the risk factors that were associated with falls, the existence of several sex-specific risk factors suggests that gender should be taken into account in designing fall-prevention strategies.

    There was an overall decline of 24% in the age-adjusted suicide rate from 1977 (13.7 per 100,000) to 2000 (10.4). The rate increased in most years from 2000 to 2015. The 2015  suicide rate (13.3) was 28% higher than in 2000. The rates for males and females  followed the overall pattern; however, the rate for males was approximately 3-5 times higher than the rate for females throughout the study period.

    Very few studies examined the prevalence and sport-related predictors of disturbed eating attitudes and behaviors (DEABs) among adolescents involved in sport practice, and their results are mixed and inconclusive. These inconsistencies are most likely due to their methodological heterogeneity and to the fact that none of these studies took into consideration the potentially relevant characteristics of the sport practice context. This study attempts to answer this limitation among French adolescents not involved or involved in various sports contexts defined based on their organization, leanness-centration, and competitive level. Participants were 335 adolescents involved in sport practice, and 435 adolescents not involved in any form of regular sport practice. The DEABs were measured using the Eating Attitudes Test-26. Global results do not showed any significant association between the status of the participants and DEAB. However, these results drastically changed when we considered the potential moderating role of sex and age on these relations. Indeed, sports involvement in general, and involvement in leanness and competitive sports were found to exert sex- and age-differentiated effects on the risks of presenting clinically significant levels of DEAB. This study suggests the importance of monitoring, preventive, and early intervention mechanisms within the context of practice, particularly for adolescent girls.

    The aim of this multicenter observational study conducted in France was to determine the prevalence of memory impairment in ambulatory patients aged≥70 years with chronic heart failure (HF). Two hundred ninety-one cardiologists recruited 912 ambulatory patients with HF (mean age 79.2±5.8 years) from January to November 2009. Memory was evaluated by the delayed-recall Memory Impairment Screen (MIS-D). Memory impairment was defined as MIS-D score≤6 and severe memory impairment as MIS-D score≤4. HF was diagnosed 4.4±4.8 years earlier and mean left ventricular ejection fraction was 43.6±12.0%. Memory impairment was found in 416 subjects (45.6%, 95% confidence interval 42.4 to 48.8) and severe memory impairment in 213 subjects (23.4%, 95% confidence interval 20.6 to 26.1), whereas cardiologists only suspected memory impairment in 109 patients (12%; before evaluation by MIS). Determinants of memory disorders included older age, lower education level, depression, history of stroke, renal failure, and less regular physical activity. The severity of memory impairment increased with increasing severity of HF (New York Heart Association classification; p<0.00001). In conclusion, memory impairment in older patients with HF is common. The use of a simple-to-use tool such as the MIS-D may identify patients at risk and enable implementation of management strategies to improve therapeutic compliance.

  19. Prevalence and course of somatic symptoms in patients with stress-related exhaustion: does sex or age matter

    2014-01-01

    Background Both mental and somatic symptoms are commonly reported in patients with stress-related problems. We have explored the prevalence of somatic symptoms in patients seeking medical care for stress-related mental health problems and followed the course of illnes alongside with that the patients receive multimodal treatment. Method This study comprises data from 228 patients (69% women, mean age 43 years) who fulfilled the criteria for Exhaustion Disorder (ED). Somatic symptoms were assessed at baseline and after 3, 6, 12 and 18 months using the one-page questionnaire Primary Care Evaluation of Mental Disorders. Prevalence of different symptoms was compared between men and women and patients, over and below 40 years of age, and possible predictors of recovery were explored. Results Tiredness and low energy are the core symptom reported by the patients. Almost all (98%) reported at least one somatic symptom and 45% reported six symptoms or more, which was similar for men and women. Nausea, gas or indigestion are the most common symptoms (67%) followed by headaches (65%) and dizziness (57%). The number of symptoms reported was significantly related to the severity of mental health problems. The only difference between the sexes was that “chest pain” and “pain or problems during sexual intercourse” were more common among males. Patients over forty more often reported “pain in arms, legs or joints, knees, hips” and this was also the only symptom that did not significantly decline during treatment. Neither sex, age, symptom duration before seeking medical care, education or any other predictor tested was shown to predict recovery in patients reporting six symptoms or more. Conclusion A heavy burden of somatic symptoms was generally seen in most patients with stress-related exhaustion. Somatic symptoms are equally common in males and females and in younger and older patients. The somatic symptoms seem to be mostly stress-related since all symptoms

    The aims of this study are to identify the most important predictors of total diagnosed and undiagnosed diabetes and estimate the mean change in the predicted probability among aged 45+ adults in China. We used baseline data collected from 2011 wave of the China Health and Retirement Longitudinal Study (CHARLS) (n = 9,513). First, we estimated the prevalence of diagnosed, measured, total diagnosed, and undiagnosed diabetes. Second, we used probit models to determine whether individual attributes, socioeconomic characteristics and behavioral health factors, including smoking, alcohol consumption, obesity, central obesity, are associated with total diagnosed and undiagnosed diabetes. We also consider other factors, including contact with medical system, hypertension and urban/rural settings. Third, we estimated average marginal effects of variables in probit models. Among Chinese people aged 45+, the prevalence of diagnosed, measured, total diagnosed and undiagnosed diabetes were 5.8% (95%CI, 5.3%-6.3%), 14.7% (95%CI, 14.0%-15.4%), 17.0% (95%CI, 16.3%-17.7%), 11.3% (95%CI, 10.6%-12.0%), respectively. The probability of total diagnosed diabetes is 3.3% (95% CI, 1.2%-5.3%) and 10.2% (95% CI, 7.0%-13.5%) higher for overweight and obesity than normal BMI, 5.0% (95% CI, 3.0%-7.1%) higher for central obesity than normal waist circumference, 5.4% (95% CI, 3.7%-7.0%) higher for hypertensive than normotensive and 1.8% (95% CI, 0.8%- 2.7%) higher in urban areas than in rural areas, respectively. The probability of undiagnosed diabetes is 2.7% (95% CI, 1.2%-4.2%) and 7.2% (95% CI, 4.7%-9.6%) higher for overweight and obesity than normal BMI, 2.6% (95% CI, 0.9%-4.4%) higher for central obesity than normal waist circumference and 2.6% (95% CI, 1.2%-4.0%) higher for hypertensive than normotensive, respectively, and -1.5% (95% CI, -2.5% to -0.5%) lower for individuals who were in contact with the medical system. Greater focus on prevention of diabetes is necessary for obesity

    This study examined individual differences in how mothers' depressive symptoms affect children's early adjustment. It tested whether problematic development among children high in negative emotionality is accentuated by (a) maternal reactivity, the negative reactivity of mothers with depressive symptoms to difficult child characteristics; and (b) child vulnerability, the susceptibility of negatively emotional children to the negative parenting of mothers with depressive symptoms. Based on 1,364 participants from the NICHD Study of Early Child Care, results showed that mothers' depressive symptoms predicted greater risk for adjustment problems at age 3 among children who as infants were high rather than low in negative emotionality. Increased risk was evident for behavior problems, low responsiveness, high separation distress, and low social competence. Mediational tests suggested that increased risk reflected maternal reactivity: the stronger mothers' depressive symptoms, the more they responded with negative parenting to children high in negative emotionality. The proposal that child vulnerability mediates the greater impact of mothers' depressive symptoms on negatively emotional children was verified only for separation distress. The results support the proposal that, when mothers are high in depressive symptoms, aversive characteristics of children and their behavior increasingly influence early adjustment and do so because they elicit negative parent behavior.

    Multiple imputation with delta adjustment provides a flexible and transparent means to impute univariate missing data under general missing-not-at-random mechanisms. This facilitates the conduct of analyses assessing sensitivity to the missing-at-random (MAR) assumption. We review the delta-adjustment procedure and demonstrate how it can be used to assess sensitivity to departures from MAR, both when estimating the prevalence of a partially observed outcome and when performing parametric causal mediation analyses with a partially observed mediator. We illustrate the approach using data from 34,446 respondents to a tuberculosis and human immunodeficiency virus (HIV) prevalence survey that was conducted as part of the Zambia-South Africa TB and AIDS Reduction Study (2006-2010). In this study, information on partially observed HIV serological values was supplemented by additional information on self-reported HIV status. We present results from 2 types of sensitivity analysis: The first assumed that the degree of departure from MAR was the same for all individuals with missing HIV serological values; the second assumed that the degree of departure from MAR varied according to an individual's self-reported HIV status. Our analyses demonstrate that multiple imputation offers a principled approach by which to incorporate auxiliary information on self-reported HIV status into analyses based on partially observed HIV serological values.

    Purpose Studies suggest that COPD prevalence may vary between countries. We conducted an ecological study of data from COPD prevalence articles to assess the influence of differences in country-level risk factors on COPD prevalence. Patients and methods Our study covered English language articles published during 2003–2014. Qualified articles used spirometry to assess COPD prevalence and used representative samples from national or subnational populations. Stepwise binomial regression was used to analyze associations between study- and country-level factors and COPD prevalence. Results Eighty articles provided 1,583 measures of COPD prevalence for subjects in different sex, age, and smoking categories for 112 districts in 41 countries. Adjusted prevalence rates for COPD were significantly lower for Australia/New Zealand and the Mediterranean and significantly higher for Latin America, compared to North America, Southeast Asia, and Northern Europe. Country-level socioeconomic development variables had an uneven and mixed association with COPD prevalence. High elevation above sea level was shown to be a protective factor for COPD. Study-level variables for the established risk factors of sex, age, and smoking explained 64% of variability in COPD prevalence. Country-level risk factors raised the explanatory power to 72%. Approximately 28% of worldwide variability in COPD prevalence remained unexplained. Conclusion Our study suggests that COPD prevalence varies across world regions, even after adjustment for established risk factors. Major country-level risk factors contributing to the worldwide epidemic of COPD remain to be investigated. PMID:27698561

    The aim of this paper was to establish whether the influence of socioeconomic factors on BMI and the prevalence of underweight and overweight changes with age. The data were obtained from 1008 schoolgirls aged 16-18 years for whom earlier data on weight and height were available. Their height and body mass were measured and their BMIs calculated. Height and weight in early life were assessed by medical records review. The girls were measured by trained school nurses at 7, 9, 14 years of age. Socioeconomic differences in BMI were found to increase with age. Parents' higher education and urban environment were associated with smaller BMI gain between the ages of 7 and 18 years. Among subjects whose mother and/or father had higher education the prevalence of underweight increased with age, and in other groups it remained at a similar level. In the younger age categories (7- and 9-year-olds) underweight was less frequent in subjects from towns than those from rural areas, while in the older categories (14, 16-18 years of age) the opposite tendency was found. As subjects grew up, there was a decline in the prevalence of overweight and obesity in all groups. Parental education and place of residence seem to influence weight status in a different way in childhood than during adolescence.

    Rey's Auditory Verbal Learning Test (RAVLT) is a widely used neuropsychological test to assess episodic memory. In the present study we sought to establish normative and discriminative validity data for the RAVLT in the elderly population using previously adapted learning lists for the Greek adult population. We administered the test to 258 cognitively healthy elderly participants, aged 60-89 years, and two patient groups (192 with amnestic mild cognitive impairment, aMCI, and 65 with Alzheimer's disease, AD). From the statistical analyses, we found that age and education contributed significantly to most trials of the RAVLT, whereas the influence of gender was not significant. Younger elderly participants with higher education outperformed the older elderly with lower education levels. Moreover, both clinical groups performed significantly worse on most RAVLT trials and composite measures than matched cognitively healthy controls. Furthermore, the AD group performed more poorly than the aMCI group on most RAVLT variables. Receiver operating characteristic (ROC) analysis was used to examine the utility of the RAVLT trials to discriminate cognitively healthy controls from aMCI and AD patients. Area under the curve (AUC), an index of effect size, showed that most of the RAVLT measures (individual and composite) included in this study adequately differentiated between the performance of healthy elders and aMCI/AD patients. We also provide cutoff scores in discriminating cognitively healthy controls from aMCI and AD patients, based on the sensitivity and specificity of the prescribed scores. Moreover, we present age- and education-specific normative data for individual and composite scores for the Greek adapted RAVLT in elderly subjects aged between 60 and 89 years for use in clinical and research settings.

    Objective: To determine the prevalence of fractures and associated risk factors in healthy Iranian children and adolescents. Methods: In this cross sectional population based study, 478 healthy Iranian children and adolescents aged 9–18 years old participated. Baseline data and bone mineral content and density have been determined. One questionnaire was completed for all individuals including previous history of fracture, its location, and level of trauma. Albumin, calcium, phosphorus, alkaline phosphatase, and vitamin D levels were measured. Results: We found a prevalence of 12.9% for fracture. (34.5% for girls and 65.5% for boys); about 71% suffered long bone fracture with distal forearm as the most common site. Totally 58% of the boys and 54% of the girls had fracture with low-energy trauma. The fracture group had lower bone mineral apparent density in the lumbar spine (0.19±0.04 vs. 0.20±0.03, p=0.04), lower serum albumin (4.6±0.5 vs 4.8±0.4, p=0.02), and higher serum alkaline phosphatase level (446±174 vs. 361±188, p=0.02) compared with non-fracture subjects. By logistic regression analysis, we found a significant association for sex, and bone mineral content of the lumbar spine with fracture (p=0.003, p=0.039). Conclusion: Compared to other studies, our subjects had lower rate of fracture. We found an association between low bone density and fracture in children and adolescents. This finding has important implications for public health. Further research may contribute to recognition of preventive measures. PMID:28246621

    Objectives To estimate the prevalence and distribution of passive smoking in the community population aged 15 years and older in China. Design A systematic review and meta-analysis of cross-sectional studies reporting the prevalence of passive smoking in China and a series of subgroup, trend and sensitivity analyses were conducted in this study. Data source The systematic review and meta-analysis, which included 46 studies with 381 580 non-smokers, estimated the prevalence and distribution of passive smoking in China. All studies were published between 1997 and 2015. Results The pooled prevalence of passive smoking was 48.7% (95% CI 44.8% to 52.5%) and was relatively stable from 1995 to 2013. The prevalence in the subgroups of gender, area, age and time varied from 35.1% (95% CI 31.8% to 38.3%) in the elderly (≥60 years) to 48.6% (95% CI 42.9% to 54.2%) in urban areas. The prevalence was lower in the elderly (≥60 years) than in those between 15 and 59 years of age (OR 1.61, 95% CI 1.44 to 1.81). The difference between females and males in urban and rural areas was not statistically significant (OR: 1.27, 95% CI 0.93 to 1.74 and OR: 1.14, 95% CI 0.82 to 1.58, respectively). In addition, a significantly increasing trend was found among males from 2002 to 2010. Heterogeneity was high in all pooled estimates (I2>98%, p<0.001). Conclusions The high and stable prevalence of passive smoking in China is raising increasing national concern regarding specific research and tobacco control programmes. Attention should be focused on young, middle-aged and male non-smokers regardless of region. PMID:27059465

    Objectives To estimate the prevalences of the main groups of congenital anomalies and to assess their trend over time. Design Population-based study of prevalences. Setting The Basque Country, Spain. Participants All births and all congenital anomalies diagnosed prenatally, at birth or during the first year of age, in all hospitals of the country, from 1999 to 2008. Main outcomes measures Total diagnosed prevalences and prevalences at birth of all chromosomal and non-chromosomal anomalies, Down's syndrome, anomalies of the nervous system, urinary, limbs, digestive system and congenital heart defects. Results Mean age (SD) of women at childbirth and the proportion of them over 35 years of age shifted from 32.1 (4.5) years, with 18.3% in 1999–2001, to 32.3 (4.7) years, with 23.9% in 2006–2008. Between 1999 and 2008, 991 cases of chromosomal anomalies and 3090 of non-chromosomal anomalies were diagnosed, which yields, respectively, total prevalences of 5.2‰ and of 16.2‰. Among chromosomal anomalies, Down's syndrome is the most frequent (2.9‰). With marginal statistical significance, the results point at an increasing trend in total diagnosed chromosomal anomalies, but a decreasing one in prevalences at birth. Among non-chromosomal congenital anomalies, congenital heart defects are the most frequent (5.2‰) one. Rates of all non-chromosomal, urinary and limb anomalies grew during the study period, whereas those of congenital heart defects and anomalies of the digestive system did not change significantly. Conclusions In the Basque Country, rates of chromosomal anomalies are higher than the overall estimated prevalence in European countries, and continue to increase slightly, which may be related to the rise in maternal age. Rates of non-chromosomal anomalies are within the European frequent range of values, and the increases observed need to be checked in the following years. PMID:24589823

    Objectives: To estimate the prevalence and risk factors of high risk human papillomavirus (HPV) infection in migrant female sex workers (FSW) according to age and geographical origin. Methods: Cross sectional study of migrant FSW attending a sexually transmitted infection (STI) clinic in Madrid during 2002. Information on sociodemographic characteristics, reproductive and sexual health, smoking, time in commercial sex work, history of STIs, HIV, hepatitis B, hepatitis C, syphilis, and genitourinary infections was collected. High risk HPV Infection was determined through the Digene HPV Test, Hybrid Capture II. Data were analysed through multiple logistic regression. Results: 734 women were studied. Overall HPV prevalence was 39%; 61% in eastern Europeans, 42% in Ecuadorians, 39% in Colombians, 29% in sub-Saharan Africans, and 24% in Caribbeans (p = 0.057). HPV prevalence showed a decreasing trend by age; 49% under 20 years, 35% in 21–25 years,14% over 36 years% (p<0.005). In multivariate analyses, area of origin (p = 0.07), hormonal contraception in women not using condoms (OR 19.45 95% CI: 2.45 to 154.27), smoking, age, and an interaction between these last two variables (p = 0.039) had statistically significant associations with HPV prevalence. STI prevalence was 11% and was not related to age or geographical origin. Conclusions: High risk HPV prevalence in migrant FSW is elevated and related to age, area of origin, and use of oral contraceptives in women not using condoms. These data support the role of acquired immunity in the epidemiology of HPV infection and identifies migrant FSW as a priority group for sexual health promotion. PMID:15681729

    Introduction African women of childbearing age are increasingly being exposed to risk factors for type 2 diabetes mellitus (T2DM), most particularly obesity. A differentiating feature of diabetes in women of childbearing age is that the disease may affect the mother and the developing fetus. Apart from mapping the extent of the problem, understanding the prevalence of T2DM in African women of childbearing age can help to galvanise targeted interventions for reducing the burden of T2DM. This is a protocol for a systematic review aiming to assess the prevalence of and risk factors for T2DM in women of childbearing age (15–49 years) in Africa. Methods and analyses We will carry out a comprehensive literature search among a number of databases, using appropriate adaptations of the African search filter to identify diabetes prevalence studies, published from 2000 to 2016, among African women of childbearing age (15–49 years) according to the WHO definition. Full copies of articles identified through searches and considered to meet the inclusion criteria will be obtained for data extraction and synthesis. The analysis of the primary outcome (prevalent diabetes) will include two steps: (1) identification of data sources and documenting estimates and (2) application of the random-effects meta-analysis model to aggregate prevalence estimates and account for between-study variability in calculating the overall pooled estimates and 95% CI for diabetes prevalence. We will assess heterogeneity and publication bias using established methods. This systematic review will be reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses Protocol (PRISMA-P) 2015. Ethics and dissemination Ethical approval is not required for this study, given that this is a protocol for a systematic review, which utilises published data. The findings of this study will be widely disseminated through peer reviewed publications and conference presentations. Trial

    OBJECTIVE: To analyze adherence to the recommended iron, zinc and multivitamin supplementation guidelines for preemies, the factors associated with this adherence, and the influence of adherence on the occurrence of anemia and iron, zinc and vitamin A deficiencies. METHODS: This prospective cohort study followed 58 preemies born in 2014 until they reached six months corrected age. The preemies were followed at a referral secondary health service and represented 63.7% of the preterm infants born that year. Outcomes of interest included high or low adherence to iron, zinc and multivitamin supplementation guidelines; prevalence of anemia; and prevalences of iron, zinc, and vitamin A deficiencies. The prevalence ratios were calculated by Poisson regression. RESULTS: Thirty-eight (65.5%) preemies presented high adherence to micronutrient supplementation guidelines. At six months of corrected age, no preemie had vitamin A deficiency. The prevalences of anemia, iron deficiency and zinc deficiency were higher in the low-adherence group but also concerning in the high-adherence group. Preemies with low adherence to micronutrient supplementation guidelines were 2.5 times more likely to develop anemia and 3.1 times more likely to develop zinc deficiency. Low maternal education level increased the likelihood of nonadherence to all three supplements by 2.2 times. CONCLUSIONS: Low maternal education level was independently associated with low adherence to iron, zinc and vitamin A supplementation guidelines in preemies, which impacted the prevalences of anemia and iron and zinc deficiencies at six months of corrected age.

    Objective: To study the prevalence of anterior dental trauma and its associated factors among 800 preschool children aged 3 to 5 years in Jaipur City, Rajasthan, India. Materials and Methods: A cross-sectional survey was conducted among children aged 3-5 years, who were enrolled in various private and public schools in Jaipur. Parents were asked to fill a form addressing socio-demographic data and clinical examinations were performed by a single dentist. Traumatic dental injuries (TDI) were assessed and recorded based on Andreasen's classification. Associated factors such as sex, socioeconomic status (SES), and the type of injury were also analyzed. The data were analyzed statistically using Statistical Package for the Social Sciences software (version 20). Results: An overall 10.2% prevalence of TDI was observed among the study population. TDI were reported to be more among male children (11.87%) compared to female children (8.14%). Enamel fractures (69%) were the most prevalent type of anterior dental trauma. Upper central incisors were the most frequently affected. The SES of the parents had little influence on the prevalence of TDI. Conclusions: The prevalence rate of dental trauma among children aged 3-5 years was 10.2%. Associated factors, such as SES, were observed to be not significantly correlated to dental trauma among the studied preschoolers. PMID:27195225

    An increasing number of acute autochthonous human hepatitis E virus (HEV)-infections was noticed in Germany and other developed countries, most likely the result of a zoonotic virus transmission from pig, wild boar and deer. Currently there is still a lack of profound data concerning the actual prevalence of HEV-specific antibodies in domestic pig herds in Germany, in particular for regions with high pig density, and its age-dependency. 2273 domestic pig sera were collected in 2011 mainly from Bavaria, North Rhine-Westphalia and Lower Saxony from areas having a high pig density. Initially, 420 randomly selected pig sera were tested in three commercially available and in two in-house HEV-antibody ELISAs. 43.6% (183/420) to 65.5% (275/420) of the sera were demonstrated to be reactive against human pathogenic HEV genotypes 1 and/or 3. The majority of sera reacted only weakly or not at all with the rat HEV antigen with very few sera showing a stronger reactivity to this antigen compared to the genotype 3 antigen. The results of all three HEV-IgG tests, i.e. the PrioCHECK(®) HEV Ab porcine ELISA kit, the ID Screen(®) Hepatitis E Indirect Multi-species ELISA kit and the genotype 3 in-house ELISA were in good accordance. Therefore, the remaining sera were tested using the PrioCHECK(®) HEV Ab porcine ELISA kit. Samples with a borderline result were finally determined by application of the conjugate-modified recomLine HEV IgG assay. A total of 1065 of the 2273 sera (46.9%) were found to be anti-HEV IgG-positive. While 38.4% (306/796) of fatteners (age between 3 and 9 months) exhibited HEV-specific antibodies, 51.4% (759/1477) of sows (age older than 9 months) exhibited anti-HEV antibodies (P<0.001). Fatteners kept in Southern Germany had a significantly higher HEV IgG prevalence compared to fatteners kept in the high pig density federal states North Rhine-Westphalia and Lower Saxony but also in German federal states with a low pig density. In conclusion, the present

    As the population ages, the need to characterize rates of cognitive impairment and dementia within demographic groups defined by age, sex, and race becomes increasingly important. There are limited data available on the prevalence and incidence of amnestic mild cognitive impairment (aMCI) and nonamnestic mild cognitive impairment (naMCI) from population-based studies. The Einstein Aging Study, a systematically recruited community-based cohort of 1944 adults aged 70 or older (1168 dementia free at baseline; mean age, 78.8 y; average follow-up, 3.9 y), provides the opportunity to examine the prevalence and incidence rates for dementia, Alzheimer dementia (AD), aMCI, and naMCI by demographic characteristics. Dementia prevalence was 6.5% (4.9% AD). Overall dementia incidence was 2.9/100 person-years (2.3/100 person-years for AD). Dementia and AD rates increased with age but did not differ by sex. Prevalence of aMCI was 11.6%, and naMCI prevalence was 9.9%. aMCI incidence was 3.8 and naMCI incidence was 3.9/100 person-years. Rates of aMCI increased significantly with age in men and in blacks; sex, education, and race were not significant risk factors. In contrast, naMCI incidence did not increase with age; however, blacks were at higher risk compared with whites, even when controlling for sex and education. Results highlight the public health significance of preclinical cognitive disease.

    The purpose of this study was to calculate the seroprevalence of Trypanosoma cruzi infection in a sample of inhabitants from a region considered to be at high risk of natural transmission of Chagas disease in Colombia. A cross-sectional study was conducted in subjects from 5 municipalities, recruited in urban and rural locations, distributed by gender according to the demographic information available. Socio-demographic information, history of potential exposure to insect vectors, blood donating, as well as symptoms suggesting cardiac disease were collected using a questionnaire. After giving written informed consent, blood specimens were obtained from 486 people to determine the serologic evidence of past exposure to T. cruzi. Infection was diagnosed when two different tests (ELISA and IHA) were positive. The seroprevalence of antibodies against T. cruzi was 16.91% considering an estimated population of 44,355 aged between 15 and 89 years (95%IC: 13.72 to 20.01). The factors significantly associated with the infection were: 1- Housing materials like vegetable material, adobe or unfinished brick walls; 2- The fact of having previous tests for Chagas disease (regardless of the result). Of note, the mean ages among infected and not infected participants were significantly different (49.19 vs. 41.66, p≤0.0001). Among the studied municipalities, the one with the highest frequency of T. cruzi infection was Nunchia, with 31.15% of the surveyed subjects. Therefore it may be concluded that T. cruzi infection is highly prevalent in the north region of Casanare, in Colombia. PMID:23505592

    Abdominal aortic calcium (AAC) is associated with incident cardiovascular disease but the age and sex-related distribution of AAC in a community-dwelling population free of standard cardiovascular disease risk factors has not been described. A total of 3285 participants (aged 50.2±9.9 years) in the Framingham Heart Study Offspring and Third Generation cohorts underwent abdominal multidetector computed tomography (MDCT) scanning during 1998-2005. The presence and amount of AAC was quantified (Agatston score) by an experienced reader using standardized criteria. A healthy referent subsample (N=1656, 803 men) free of hypertension, hyperlipidemia, diabetes, obesity and smoking was identified, and participants were stratified by sex and age group (<45, 45-54, 55-64, 65-74, ≥75 years). The prevalence and burden of AAC increased monotonically and supralinearly with age in both sexes but was greater in men than women in each age group. Below age 45 <16% of referent-subsample participants had any quantifiable AAC, while above age 65 nearly 90% of referent participants had >0 AAC. Across the entire study sample, AAC prevalence and burden similarly increased with greater age. Defining the 90th percentile of referent group AAC as “high,” the prevalence of high AAC was 19% for each sex in the overall study sample. AAC also increased across categories of 10-year coronary heart disease risk, as calculated using the Framingham Risk Score, in the entire study sample. We found AAC to be widely prevalent, with the burden of AAC associated with 10-year coronary risk, in a white, free-living adult cohort. PMID:22727181

    Cervical screening for carcinogenic human papillomavirus (HPV) infection is being considered for low income countries. Effectiveness requires targeted screening in older women in whom prevalent infections are more likely to be persistent and predictive of precancer. Some studies in West Africa have found unusually high HPV prevalences across all adult ages, that may reduce the positive predictive value (PPV) of HPV-based screening, if positivity in older women does not sufficiently predict elevated risk. We conducted a population-based study in rural Nigeria to identify HPV prevalence and associated cervical abnormalities. Using stratified random sampling, we enrolled women age 15+. Non-virgins had a cervical exam including liquid-based cytology and PCR HPV DNA testing from residual cytology specimens. Two-thirds of invited women participated, and 14.7% had detectable carcinogenic HPV, a proportion that did not decline with age (p-trend=.36) and showed slight peaks in the 15–29 and 60–69 age groups. Among women of the age typically considered for screen-and-treat programs (30–49 years), 12.8% were HPV-positive and the PPV for high-grade or worse cytology was 16.4%. Comparatively, women age <30, were more likely to be HPV-positive (18.9%, p=.03) with a lower PPV (4.2% p=.05). Among women age 50+ (typically excluded from screening in resource-poor settings because inexpensive treatment is not available), HPV positivity was 14.2% with a PPV of 13.9%. In Irun and similar settings where HPV does not decline with age, HPV-based screen-and-treat programs might be feasible for mid-adult women, since prevalence is sufficiently low, positivity predicts elevated risk of more easily treated precancer.

    Background: The potential impact of elevated Lipoprotein (a) [Lp(a)] levels on retinal venous occlusive (RVO) diseases with regard to age and various risk factors has not been studied extensively. Patients and Methods: In a retrospective case-control study, thrombophilia data of 106 young patients (< 60 years at the time of the RVO or a previous thromboembolic event) with RVO and 76 healthy subjects were evaluated. Results: Elevated Lp(a) plasma levels were significantly more prevalent among RVO patients (29.2 %) than among controls (9.2 %; p = 0.0009). Lp(a) levels were found to be significantly (p = 0.012) different between patients and controls. Moreover, we found that an unusual personal or family history of thromboembolism was a strong predictor of elevated Lp(a) (p = 0.03). We observed a significant correlation between elevated Lp(a) and other coagulation disorders (p = 0.005). Multivariate analysis showed that elevated lipoprotein(a) levels (OR: 3.5; p = 0.003) were an independent risk factor for the development of RVO. Conclusions: Elevated plasma levels of Lp(a) are associated with the development of RVO. Selective screening of young patients and subjects with a personal or family history of thromboembolism may be helpful in identifying RVO patients with elevated Lp(a).

    Background Although depression appears to decrease in late life, this could be due to misattribution of depressive symptoms to physical disorders that increase in late life. Methods We investigated this issue by studying age differences in comorbidity of DSM-IV major depressive episodes (MDE) with chronic physical conditions in the WHO World Mental Health (WMH) surveys, a series of community epidemiological surveys carried out in 10 developed countries (n = 51,771) and 8 developing countries (n = 37,265). MDE and other mental disorders were assessed with the Composite International Diagnostic Interview (CIDI). Organic exclusion rules were not used to avoid inappropriate exclusion of cases with physical comorbidity. Physical conditions were assessed with a standard chronic conditions checklist. Results Twelve-month DSM-IV/CIDI MDE was significantly less prevalent among respondents ages 65+ than younger respondents in developed but not developing countries. Prevalence of comorbid mental disorders generally either decreased or remained stable with age, while comorbidity of MDE with mental disorders generally increased with age. Prevalence of physical conditions, in comparison, generally increased with age, while comorbidity of MDE with physical conditions generally decreased with age. Depression treatment was lowest among the elderly in developed and developing countries. Conclusions The weakening associations between MDE and physical conditions with increasing age argue against the suggestion that the low estimated prevalence of MDE among the elderly is due to increased confounding with physical disorders. Future study is needed to investigate processes that might lead to a decreasing impact of physical illness on depression among the elderly. PMID:20037917

    The objective of this study was to develop prediction models for the serum IgG concentration in critically ill calves based on indirect assays and to assess if the predictive ability of the models could be improved by inclusion of age, clinical covariates, and/or laboratory covariates. Seventy-eight critically ill calves between 1 and 13 days old were selected from 1 farm. Statistical models to predict IgG concentration from the results of the radial immunodiffusion test, the gold standard, were built as a function of indirect assays of serum and plasma protein concentrations, zinc sulfate (ZnSO4) turbidity and transmittance, and serum γ-glutamyl transferase (GGT) activity. For each assay 4 models were built: without covariates, with age, with age and clinical covariates (infection and dehydration status), and with age and laboratory covariates (fibrinogen concentration and packed cell volume). For the protein models, dehydration status (clinical model) and fibrinogen concentration (laboratory model) were selected for inclusion owing to their statistical significance. These variables increased the coefficient of determination (R (2) ) of the models by ≥ 7% but did not significantly improve the sensitivity or specificity of the models to predict passive transfer with a cutoff IgG concentration of 1000 mg/dL. For the GGT assay, including age as a covariate increased the R (2) of the model by 3%. For the ZnSO4 turbidity test, none of the covariates were statistically significant. Overall, the R (2) of the models ranged from 34% to 62%. This study has provided insight into the importance of adjusting for covariates when using indirect assays to predict IgG concentration in critically ill calves. Results also indicate that ZnSO4 transmittance and turbidity assays could be used advantageously in a field setting.

  3. Body measurements and the variability of sitting postures at preschool age as preconditions for an optimal adjustment of chairs and tables.

    Preschool age is a biological stage of intensive longitudinal growth with high plasticity of the growing body and of body postures. It is the period where children learn to persist in a sitting posture for a longer time and to use furniture like chairs or other body supporting systems. The growing body shows a special sensitivity for the manifestation of inappropriate postures. In this study the development of body measurements and sitting behaviour of preschool age children is investigated as a precondition for an optimal adjustment of seats and desks to the growing body. Accordingly to the instructions of Knussmann (1988) and Jiirgens (1988) 6 body measurements were taken from 122 German children aged 3 to 7 years from Potsdam, Province Brandenburg. Additionally, every child was videotaped for 10 minutes while crayoning in a sitting position of its own choice using a chair and a desk. To analyse the tapes, the software Noldus Observer was used and examined, picture by picture, to define the different types of sitting postures as well as the duration of persistence in a posture and the number of changes of postures. The used chairs and desks were also measured. Furthermore, the data of the furniture guideline DIN ISO 5970 (DIN, 1981), which regulates the dimensions of furniture for sitting in educational institutions, were compared with the results of the body measurements and with the dimensions of the furniture used by the children.

    Comorbidities had considerable effects on the development of postoperative ileus (POI). The primary aim of the present study was to determine the influence of the age-adjusted Charlson comorbidity index (ACCI) score on the risk of prolonged POI in patients with colorectal cancer who underwent surgical resection. Using the electronic Hospitalization Summary Reports, we identified 11,397 patients with colorectal cancer who underwent surgical resection from 2013 through 2015. Logistic regression models were applied to evaluate the effect of the ACCI score on the risk of prolonged POI. The ACCI score had a positive graded association with the risk of prolonged POI in both colon and rectal cancer (P for trend < 0.05). Among patients with rectal cancer, after adjusting for potential confounders, those with an ACCI score of 4-5 had a 108% higher risk of prolonged POI than those with an ACCI score of 0-1 (odds ratio [OR], 2.08; 95% confidence interval [CI], 1.09-3.98), and those with an ACCI score of ≥ 6 had a 130% higher risk (OR, 2.30; 95% CI, 1.08-4.89). Among patients with colon cancer, those with an ACCI score of ≥ 6 had a 47% greater risk of prolonged POI than those with an ACCI score of 0-1 (OR, 1.47; 95% CI, 1.07-2.02). These findings suggested that a higher ACCI score was an independent predictor of the development of prolonged POI.

    Previous studies on type 2 diabetes mellitus in the Islamic Republic of Iran were mainly performed in provinces with large populations. This study determined the prevalence and risk factors of diabetes mellitus in an adult population (40-80 years old) from Yazd district. Multistage, systematic cluster random sampling was used in a crosssectional, population-based survey. Demographic, clinical and anthropometric data were collected, with diabetes defined as fasting blood sugar ≥ 7 mmol/L or a positive medical history of diabetes. The age- and sex-standardized prevalence of diabetes in 2090 individuals participants was 24.5% (95% CI: 22.2-26.8%), including 10.5% new cases. For each year of ageing, the prevalence of diabetes increased significantly by 4% and this trend was more pronounced in females than males. Low education and hypertension were significantly associated with diabetes prevalence. The prevalence of diabetes mellitus in Yazd is greater than the average levels nationwide and those of nearby countries.

    The aim of this study was to analyze prevalence data for diabetes mellitus obtained from a household interview of a random sample of the general population by the Department of Health of the Commonwealth of Puerto Rico for the years 1975-1986. Details of the prevalence rate by sex and age were analyzed for the years 1981, 1984, 1985, and 1986 and for the urban and rural population in 1985. The mean prevalence rate of known cases of diabetes showed a tendency to increase from 3.1% in 1975 to 5.1% in 1986. Prevalence rates adjusted for age and sex showed an increase in the mean prevalence for 1986 compared with that of 1981. The prevalence rate was significantly higher for the rural population for the age-group 45-64 yr old and for the urban population for the age-group greater than or equal to 65 yr. The prevalence rate compares with that of Mexican Americans and Puerto Ricans in the New York City area. On the basis of the prevalence data, approximately 90% of the diabetic population is non-insulin dependent and 10% are insulin dependent. Major risk factors thought to explain the increased prevalence of non-insulin-dependent diabetes are increasing longevity of the Puerto Rican population, genetic predisposition, obesity, and changes in life-styles. In conclusion, Puerto Ricans, as other Hispanic Americans, have a higher prevalence of diabetes than the white American population.

    Despite the use of different methodologies, target populations, and clinical definitions of sexual problems, recent epidemiological studies have shown that the occurrence of sexual difficulties is a very common experience among men from the general population regardless of their age. The objective of this study was to present epidemiological data on the prevalence of sexual difficulties in a community sample of 650 sexually active Portuguese men, stratified by age, marital status, and educational level. Participants completed a self-reported questionnaire assessing sexual function in the previous four weeks (International Index of Erectile Function). Results showed that sexual difficulties were relatively common among this sample. Rapid ejaculation was the most frequently reported sexual difficulty (23.2%), followed by erectile difficulties (10.2%), orgasm problems (8.2%), and low desire (2.9%) in the previous four weeks. With the exception of rapid ejaculation, all categories showed age-specific prevalence rates, with sexual difficulties increasing gradually in men above age 45. Age was a significant predictor of all sexual difficulties except rapid ejaculation, and lower educational levels were related to orgasm difficulties. Findings are consistent with the majority of epidemiological studies indicating a high prevalence of sexual difficulties among men in the general population and highlight the importance and the need to implement sexual health promotion programs in the target population.

  8. Population prevalence of ultrasound features of osteoarthritis in the hand, knee and hip at age 63 years: the Newcastle thousand families birth cohort

    PubMed Central

    2014-01-01

    Background Musculoskeletal ultrasound has been found to be more sensitive than radiographs in detecting osteophytes. Our objective was to measure the prevalence of features of osteoarthritis (OA), in the dominant hand, knees and hips using ultrasound, within the Newcastle Thousand Families birth cohort. Methods Participants were aged 61–63 (mean 63) years. Knee images were scored for presence of osteophytes and effusion. Hip images were scored for the presence of osteophytes and femoral head abnormality. The first carpometacarpal joint, metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints of the index finger (dominant hand) were imaged for osteophytes. Results Among 311 participants, prevalence of osteophytes at the distal interphalangeal joint was 70% while it was 23%, 10% and 41% for index proximal interphalangeal and metacarpophalangeal and thumb base carpometacarpal joints respectively. Prevalence of knee osteophytes was 30%, hip OA was 41%. Prevalence of knee effusions was 24% (right) and 20% (left). Ultrasound evidence of generalised OA (48%) and isolated hand OA (31%) was common, compared to isolated hip or knee OA (5%) and both hip and knee OA (3%). Conclusion This is the first study to assess prevalence of ultrasound features of OA in a population-based sample. The higher prevalence of hand/hip OA, when compared to previous radiographic studies, supports the hypothesis that ultrasound is more sensitive than radiography in detecting OA, particularly for osteophytes.

    Background Diarrhoea is the second leading cause of child mortality worldwide. Low- and middle-income countries are particularly burdened with this both preventable and treatable condition. Targeted interventions include the provision of safe water, the use of sanitation facilities and hygiene education, but are implemented with varying local success. Objective To determine the prevalence of and factors associated with diarrhoea in children under five years of age in rural Burundi. Design A cross-sectional survey was conducted among 551 rural households in northwestern Burundi. Areas of inquiry included 1) socio-demographic information, 2) diarrhoea period prevalence and treatment, 3) behaviour and knowledge, 4) socio-economic indicators, 5) access to water and water chain as well as 6) sanitation and personal/children's hygiene. Results A total of 903 children were enrolled. The overall diarrhoea prevalence was 32.6%. Forty-six per cent (n=255) of households collected drinking water from improved water sources and only 3% (n=17) had access to improved sanitation. We found a lower prevalence of diarrhoea in children whose primary caretakers received hygiene education (17.9%), boiled water prior to its utilisation (19.4%) and were aged 40 or older (17.9%). Diarrhoea was associated with factors such as the mother's age being less than 25 and the conviction that diarrhoea could not be prevented. No gender differences were detected regarding diarrhoea prevalence or the caretaker's decision to treat. Conclusions Diarrhoea prevalence can be reduced through hygiene education and point-of use household water treatment such as boiling. In order to maximise the impact on children's health in the given rural setting, future interventions must assure systematic and regular hygiene education at the household and community level.

    Abdominal aortic calcium (AAC) is associated with incident cardiovascular disease. However, the age- and gender-related distribution of AAC in a community-dwelling population free of standard cardiovascular disease risk factors has not been described. A total of 3,285 participants (aged 50.2 ± 9.9 years) in the Framingham Heart Study Offspring and Third Generation cohorts underwent abdominal multidetector computed tomography from 1998 to 2005. The presence and amount of AAC was quantified (Agatston score) by an experienced reader using standardized criteria. A healthy referent subsample (n = 1,656, 803 men) free of hypertension, hyperlipidemia, diabetes, obesity, and smoking was identified, and participants were stratified by gender and age (<45, 45 to 54, 55 to 64, 65 to 74, and ≥75 years). The prevalence and burden of AAC increased monotonically and supra-linearly with age in both genders but was greater in men than in women in each age group. For those <45 years old, <16% of the referent subsample participants had any quantifiable AAC. However, for those >65 years old, nearly 90% of the referent participants had >0 AAC. Across the entire study sample, AAC prevalence and burden similarly increased with greater age. Defining the 90th percentile of the referent group AAC as "high," the prevalence of high AAC was 19% for each gender in the overall study sample. The AAC also increased across categories of 10-year coronary heart disease risk, as calculated using the Framingham Risk Score, in the entire study sample. We found AAC to be widely prevalent, with the burden of AAC associated with 10-year coronary risk, in a white, free-living adult cohort.

    Age-adjusted D-dimer (AADD) appears to increase the proportion of patients in whom pulmonary embolism (PE) can safely be excluded compared with conventional D-dimer (CDD), according to a limited number of studies. The aim if this study was to assess whether the use of an AADD might safely increase the clinical usefulness of CDD for the diagnosis of PE in our setting. Three hundred and sixty two consecutive outpatients with clinically suspected PE in whom plasma samples were obtained to measure D-dimer were included in this post hoc analysis of a previous study. CDD cutoff value was 500 ng/mL and AADD was calculated as (patient's age × 10) ng/mL in patients aged >50. Sensitivity, specificity, clinical usefulness (i.e., proportion of true-negative tests among all patients with suspected PE), and the proportion of false negatives were calculated for both AADD and CDD among patients with low-to-moderate clinical probability of PE according to Well's criteria. PE was confirmed in 98 patients (27%). Among 331 patients with low-to-moderate clinical probability of PE, sensitivity and clinical usefulness were 100 and 27.8% for CDD, respectively, and 100 and 36.5% for AADD, respectively. In 29 patients aged >50 with CDD >500 ng/mL, AADD showed values under its normal cutoff point, without false negatives for the diagnosis of PE (0%, 95% CI 0-11%). AADD increases clinical usefulness notably with respect to that of CDD in patients with clinical suspected PE without losing sensitivity in our cohort. The use of AADD apparently does not reduce the safety of CDD for the exclusion of PE.

    AIM To assess the prevalence, causes, and risk factors for blindness and visual impairment among elderly (≥60 years of age) Chinese people in a metropolitan area of Shanghai, China. METHODS Random cluster sampling was conducted to identify participants among residents ≥60 years of age living in the Xietu Block, Xuhui District, Shanghai, China. Presenting visual acuity (PVA) and best-corrected visual acuity (BCVA) were checked by the Early Treatment Diabetic Retinopathy Study (ETDRS) visual chart. All eligible participants underwent a comprehensive eye examination. Blindness and visual impairment were defined according to World Health Organization (WHO) criteria. RESULTS A total of 4190 persons (1688 men and 2502 women) participated in the study, and the response rate was 91.1%. Based on PVA, the prevalence of blindness was 1.1% and that of visual impairment was 7.6%. Based on BCVA, the prevalence of blindness and visual impairment decreased to 0.9% and 3.9%, respectively. Older (≥80 years of age) women, with low educational levels and smoking habits, exhibited a significantly greater chance for blindness and visual impairment than did those with high educational levels and no smoking habits (P<0.05). Based on PVA and BCVA, the main causes of blindness were cataract, myopic maculopathy, and age-related macular degeneration (AMD). CONCLUSION Our findings help to identify the population in need of intervention, to highlight the need for additional eye healthcare services in urban China. PMID:28149791

    Purpose To define the prevalence of distorted body image in 10–24-year-old Koreans and determine its relationship with sex, age, body weight status, and disordered eating behaviors. Methods A total of 3,227 young Koreans were recruited from elementary, middle, and high schools, as well as from universities. The participants completed a self-reported questionnaire on body image, eating behaviors (Eating Attitude Test-26), and body weight status. Results The prevalence of a distorted body image in males was 49.7% and that in females was 51.2%. Distorted body image was more frequent in adolescents (age, 10–17 years) than in young adults (age, 18–24 years). The highest prevalence (55.3%) was reported in female elementary school students (age, 10–12 years). Distorted body image was associated with disordered eating behaviors and abnormal body weight status. Conclusion These results suggest that distorted body image is a public health problem, given its high frequency in young Koreans, and that it is associated with abnormal body weight status and disordered eating behaviors.

    Malnutrition in childhood is a dramatic indicator of poor socio-economical status worldwide. To recognize and reveal the socio-demographic features is crucial, especially for developing countries. Our aim was to investigate the prevalence and association with sociodemographic variables of malnutrition in 0-5 years old children in Van, Turkey. A total of 702 children are included in this cross-sectional study. Demographic features of subject including age, gender, family characteristics and other data were obtained. Nutritional assessment was done using anthropometric indices including weight-for-age, height-for-age, weight-for-height, head circumference and body mass index-for-age. Multivariate logistic regressions were carried out to assess malnutrition-associated factors. Prevalence of underweight, stunting and wasting were 19.7, 17.7 and 16.2%, respectively. Socio-demographic variables that statistical significantly in association with malnutrition were low monthly family income, educational level and employment status of father, parental consanguinity, number of pregnancies, regular intake of vitamin D and history of prematurity. The prevalence of children with head circumference-z score ≤2SD and body mass index-for-age ≤2SD were 9.8 and 16.3%, respectively. Multivariate analysis detected following risk factors for these indices; low monthly family income, history of prematurity, unemployed father and the period between pregnancies (1-2 years). We found that prevalence of malnutrition in the city of Van, was still higher than more developed regions of Turkey. The associated risk factors of malnutrition should be specifically interpreted by health professionals and also by government authorities that are responsible for making practical politics of public health.

    Objective: To explore the prevalence of physical activity time <1 hour and related factors in students aged 9-22 years in China. Methods: A total of 220 159 students (110 039 boys and 110 120 girls) aged 9-22 years who completed the questionnaire of physical activity and lifestyle behaviors were selected from " 2014 National Physical Fitness and Health Surveillance" for the current study. All the participants were divided into 2 groups, i.e. physical activity time <1 hour and physical activity time ≥1 hour according the suggestion of Central Government, stratified by age and gender. χ(2) tests were used to compare the difference in the prevalence of physical activity time <1 hour between boys and girls in every age groups. Univariate and multivariate log-binomial regression models were used to explore the factors that influenced the prevalence of physical activity time <1 hour. Results: The boy's prevalence of physical activity time <1 hour was 73.3%, with the lowest (57.0%) in 9-years-old group, and highest (82.5%) in 18 years old group. The girl's prevalence of physical activity time <1 hour was 79.1%, with the lowest (60.1%) in 9-years-old group, and highest (89.8%) in 21 years old group. Overall, The prevalence of physical activity time <1 hour was significantly higher in girls than in boys (P<0.001), and the prevalence were significantly higher in girls than in boys in all the age groups (P<0.001), and it was observed that the prevalence of physical activity <1 hour increased with age in both boys and girls (P<0.001). Multivariate log-binomial regression model found that being girl (PR=1.05, 95%CI: 1.05-1.06), parents' disliking children to participate physical activity (PR=1.08, 95% CI: 1.07-1.09), heavy homework (PR=1.13, 95% CI: 1.12-1.14), long homework time (PR =1.08, 95%CI: 1.07-1.08), long time spending on electronic screen watching (PR=1.01, 95%CI: 1.00-1.01) and disliking physical class (PR=1.11, 95%CI: 1.10-1.12) could be the risk factors for

    The annual prevalence of psychotropic medication use exceeds 10 percent in Europe and the United States, the prevalence being higher among the divorced than the married. We analysed changes in the three-month prevalence of psychotropic medication use (psycholeptics and psychoanaleptics excluding medication for dementia) by proximity to divorce, sex, medication type and socio-demographic characteristics, using register-data on 304,111 Finns between 25 and 64 years of age, of whom 23,956 divorced between 1995 and 2003 and 142,093 were continuously married from 1995 to 2004. Five years before divorce, men and women already displayed about one percentage point higher prevalence of psychotropic medication use than those who continued their marriage. The excess prevalence increased with approaching divorce and peaked six to nine months before divorce, reaching 7.3 percent (95% CI 6.8-8.0) among divorcing men and 8.1 percent (95% CI 7.5-8.8) among divorcing women. The peak was followed by an 18-month decline, after which the excess compared to the continuously married settled at nearly three percentage points. The excess was not due to being socio-economically disadvantaged, and socio-demographic factors also seemed to have few modifying effects. The changes in prevalence were largest for antidepressants and almost non-existent for antipsychotics. Our results suggest that the high prevalence of psychotropic medication use among the divorced results both from selective factors already present five years before divorce and the acute and long-term causal effects of becoming and being divorced. Counselling is needed for individuals in the process of divorce, rather than economic support for divorced individuals.

  18. Prevalence gradients of Friedreich's ataxia and R1b haplotype in Europe co-localize, suggesting a common Palaeolithic origin in the Franco-Cantabrian ice age refuge.

    Combining data from epidemiological studies in Friedreich's Ataxia (FRDA) and patient organization membership lists, shows that FRDA prevalence exhibits large regional differences in Europe with a prevalence gradient from west to east. Highest levels are observed in northern Spain, south of France and Ireland, lowest levels in Scandinavia and Russia. The observed distribution of FRDA in Europe co-localizes with the gradient of the chromosomal R1b marker as detected within west Europe. This gradient is either derived from Palaeolithic migrations out of the Franco-Cantabrian Ice age refuge or from Neolithic migrations entering west Europe with the advance of agriculture. FRDA prevalence may have been increased in this population anytime after its separation from the closely related R1a carrying group. East European populations with a high frequency of the R1a marker show 10 fold lower prevalence of FRDA, indicating that the FRDA mutation was present in the common ancestor and was increased in the R1b carrying group. The FRDA carrying population went through a Palaeolithic population bottleneck supporting the view that the observed FRDA distribution and potentially the R1b distribution are derived from Palaeolithic migrations out of the Franco-Cantabrian ice age refuge.

    Due to their probable role in the spread of Asian highly pathogenic avian influenza (HPAI) H5N1 virus, and in order to explore its implication in the low pathogenic avian influenza (LPAI) virus epidemiology, mute swans represent one particular wild bird species specifically targeted in the avian influenza (AI) surveillance elaborated in Belgium. A total of 640 individual mute swans have been sampled during a 4-yr AI surveillance program (2007-2010) to determine the AI seroprevalence and viroprevalence in this species; all were analyzed through age, temporal, and habitat (flowing and stagnant water) factors. Using a nucleoprotein (NP)-based ELISA, a global antibody prevalence of 35% has been found and was characterized by two peaks in the winter and the summer that might be indicative of a greater LPAI virus circulation in the autumn than in the spring. A significantly higher antibody prevalence was detected in adult swans (53.8%) as compared to juveniles (15.5%). In contrast, a low prevalence of infection (2.7%) was found, mainly in juvenile mute swans and only during the autumn migration period. Interestingly, an impact of water habitat was observed based on the comparison of the antibody prevalence and prevalence of infection from swan populations living on stagnant water vs. flowing water, suggesting that stagnant water provides a more-favorable environment for LPAI persistence and transmission.

    Preventive chemotherapy with praziquantel is recommended in adults by the World Health Organization when prevalence of schistosomiasis in school-aged children (SAC) is ≥ 50%. This study ascertained the value of this threshold in predicting prevalence and intensity of Schistosoma hematobium (SH) infection in adults in central Nigeria. We evaluated urogenital schistosomiasis prevalence in 1,164 adults: 659 adults in 12 communities where mean hematuria among SAC in 2008 was 26.6% and 505 adults in 7 communities where the mean hematuria among SAC in 2008 was 70.4%. No statistically significant differences were found between the two groups of adults in prevalence of hematuria, prevalence of SH eggs, or intensity of infections. We conclude that, in this setting, the SAC threshold is not useful for treatment decisions in adults. Given the increased risk of subtle morbidity or urogenital schistosomiasis as a risk factor for human immunodeficiency virus (HIV), more liberal treatment of adults with praziquantel is warranted.

    Objective The double burden of malnutrition affects many low and middle-income countries. This study aimed to: a) determine temporal trends in the prevalence of underweight, stunting, and at risk of overweight/ overweight or obesity in Indonesian children aged 2.0–4.9 years; and b) examine associated risk factors. Design A repeated cross-sectional survey. This is a secondary data analysis of waves 1, 2, 3, and 4 (1993, 1997, 2000, and 2007) of the Indonesian Family Life Survey, which includes 13 out of 27 provinces in Indonesia. Height, weight and BMI were expressed as z-scores (2006 WHO Child Growth Standards). Weight-for-age-z-score <-2 was categorised as underweight, height-for-age-z-score <-2 as stunted, and BMI-z-score >+1, >+2, >+3 as at-risk, overweight and obese, respectively. Results There are 938, 913, 939, and 1311 separate children in the 4 waves, respectively. The prevalence of stunting decreased significantly from waves 1 to 4 (from 50.8% to 36.7%), as did the prevalence of underweight (from 34.5% to 21.4%). The prevalence of ‘at-risk’/overweight/obesity increased from 10.3% to 16.5% (all P<0.01). Stunting and underweight were related to lower birth weight, being breastfed for 6 months or more, having parents who were underweight or had short stature, and mothers who never attended formal education. Stunting was also higher in rural areas. Being at-risk, or overweight/obese were closely related to being in the youngest age group (2–2·9 years) or male, having parents who were overweight/obese or having fathers with university education. Conclusions The double burden of malnutrition occurs in Indonesian children. Development of policy to combine the management of chronic under-nutrition and over-nutrition is required. PMID:27167973

    Objective Hypertension is the major driver of the cardiovascular epidemic facing Indonesia in the 21st century. Understanding the socioeconomic inequalities associated with hypertension is essential for designing effective intervention strategies. The aim of the current study was to use sub-nationally representative survey data to examine socio-demographic inequalities in the prevalence, diagnosis and management of hypertension in Indonesian adults. Methods We investigated factors associated with hypertension prevalence, diagnosis, treatment and control using data on self-reported diagnosis and treatment, and blood pressure measurements, collected from 9755 respondents aged 40 years and up in the 2007 Indonesian Family Life Survey (IFLS 4). Results Age-standardized prevalence of hypertension among the study participants was 47.8% (95% CI: 46.8, 48.9), of which almost 70% were undiagnosed. Hypertension was significantly higher in women than men (52.3% versus 43.1%, p-value<0.001). Prevalence of hypertension increased significantly with ageing (Pfor trend <0.001). Over 91% (men: 92.1%, women: 90.0%) of hypertension cases were uncontrolled. Gender, education and socioeconomic status had differential impact on the diagnosis of hypertension and in receiving treatment. Conclusions Overall, less than a third were aware of their hypertension and a quarter of those on medication had their blood pressure effectively controlled. Men and those of younger age were more vulnerable to have undiagnosed and untreated hypertension. Substantial effort should be given to improve awareness about the condition and making provision for early diagnosis and treatment. PMID:27556532

    Introduction Information on folate and vitamin B12 deficiency rates in Guatemala is essential to evaluate the current fortification program. The objectives of this study were to describe the prevalence of folate and vitamin B12 deficiencies among women of childbearing age (WCBA) in Guatemala and to identify vulnerable populations at greater risk for nutrient deficiency. Methods A multistage cluster probability study was designed with national and regional representation of nonpregnant WCBA (15–49 years of age). Primary data collection was carried out in 2009–2010. Demographic and health information was collected through face-to-face interviews. Blood samples were collected from 1,473 WCBA for serum and red blood cell (RBC) folate and serum vitamin B12. Biochemical concentrations were normalized using geometric means. Prevalence rate ratios were estimated to assess relative differences among different socioeconomic and cultural groups including ethnicity, age, education level, wealth index and rural versus urban locality. Results National prevalence estimates for deficient serum (<10 nanomoles per liter [nmol/L]) and RBC folate (<340 nmol/L) concentrations were 5.1% (95% CI 3.8, 6.4) and 8.9% (95% CI 6.7, 11.7), respectively; for vitamin B12 deficiency (<148 pmol/L) 18.5% (95% CI 15.6, 21.3). Serum and RBC folate deficiency prevalences were higher for rural areas than for urban areas (8.0% vs. 2.0% and 13.5% vs. 3.9%, respectively). The prevalence of RBC folate deficiency showed wide variation by geographic region (3.2%–24.9%) and by wealth index (4.1%–15.1%). The prevalence of vitamin B12 deficiency also varied among regions (12.3% –26.1%). Conclusions In Guatemala, folate deficiency was more prevalent among indigenous rural and urban poor populations. Vitamin B12 deficiency was widespread among WCBA. Our results suggest the ongoing need to monitor existing fortification programs, in particular regarding its reach to vulnerable populations.

    Nonalcoholic fatty liver disease (NAFLD) has been found to be highly prevalent in psoriatic patients. Adult onset psoriasis could be divided into either early or late onset psoriasis. The associations between NAFLD and related metabolic comorbidities and age at onset of psoriasis have not yet been investigated. Our study was to evaluate the associations between prevalence of NAFLD and related metabolic conditions and early, late, and childhood onset psoriasis. A cross-sectional observational study was conducted on patients with moderate to severe plaque psoriasis. Data on clinical characteristics of NAFLD and related metabolic diseases (diabetes, hypertriglyceridemia, hyperuricemia, and metabolic syndrome) were collected. The prevalence of NAFLD in 439 patients (mean: 51±14 years, range: 18–85 years) was 55.8%. NAFLD was frequently identified in early onset patients (74.2%), and this diagnosis was particularly common in patients currently younger than 40 (85.3%). Diabetes was the least prevalent component of metabolic syndrome in early onset patients with metabolic syndrome but the most often found component in late onset ones. Patients with childhood onset psoriasis had the lowest frequencies of all metabolic comorbidities except hyperuricemia among the three groups. In the multivariate analyses, early onset was independently and positively associated with NAFLD, hypertriglyceridemia and hyperuricemia and independently and negatively associated with diabetes among early and late onset patients. The results suggested prevalence of NAFLD and related metabolic comorbidities was associated with age at onset of moderate to severe plaque psoriasis. Early onset of psoriasis was independently associated with greater odds of NAFLD, hypertriglyceridemia, hyperuricemia and smaller odds of diabetes compared to late onset. Early onset patients have metabolic syndrome mainly related to lipid disorders and abnormal glucose metabolism was not often involved. PMID:28099469

    ABSTRACT Objectives: The aim of the study was to review published evidence and the opinion of practising clinicians on the prevalence and long-term health consequences of functional gastrointestinal symptoms in infants younger than 12 months. Methods: PubMed was searched from inception to November 2014 to find articles reporting the prevalence and long-term health outcomes of infantile colic, regurgitation, functional constipation, functional diarrhoea, and dyschezia in infants younger than <12 months. A questionnaire was sent to practising clinicians worldwide, and a group of 15 international experts met to discuss the likely frequency and longer-term consequences of these symptoms. Results: The literature search identified 30 studies reporting the prevalence of infantile colic (2%–73%), 13 that of regurgitation (3%–87%), 8 that of functional constipation (0.05%–39.3%), 2 that of functional diarrhoea (2%–4.1%), and 3 that of dyschezia (0.9%–5.6%). The studies varied in design, populations investigated, and definition of the symptoms. Questionnaires were received from 369 respondents. The experts agreed that the likely prevalences for colic, regurgitation, and functional constipation were 20%, 30%, and 15%, respectively. The limited data in the literature for functional diarrhoea and dyschezia suggest prevalences <10%. Infantile colic may be associated with future health problems in a subset of infants. Conclusions: Functional gastrointestinal symptoms appear to occur in a significant proportion of infants younger than 12 months and may have an impact on future health outcomes. Prospective collection of data according to agreed criteria is needed to obtain more accurate estimates of the prevalence and consequences of these symptoms. PMID:26308317

    This study investigated the impact of 2 coccidiosis control systems (vaccine vs anticoccidial) and 2 feeding plans (standard energy vs low energy content, the latter supplemented with threonine and enzymes in the second half of the production cycle) on white striping (WS) prevalence and severity in chicken broiler breasts at commercial slaughter age (51 d). The age of lesion onset was also investigated with the sacrifice of 80 chicks at 12, and 80 chicks at 25 d of age. Seven hundred and twenty ROSS 708 strain male chicks were divided into 4 groups: a non-vaccinated group fed with standard diet (CONTROL); two groups vaccinated against coccidiosis but fed either a standard diet (VACC) or a low-energy diet supplemented with threonine and enzymes (VACC-LE plus); and a fourth group fed a standard diet containing anticoccidial additive except during the finishing period (COX). After live performance, yields, and fillet pH were measured, the breasts were weighed and scored as level 0 (no WS), level 1 (moderate WS), and level 2 (severe WS) at each of the 3 ages; data were covariate for slaughter weight. The results suggest an ameliorative effect of coccidiosis control systems when compared to the control group in terms of live weight, breast yield, and whole breast weight, with heavier fillets characterized by higher pH values. WS appeared at 25 d of age with an average prevalence of 11.5% and with lesions of moderate severity. There were no statistically significant differences due to the experimental treatment at this age. At commercial slaughter age, total average prevalence was 96%, with COX birds showing higher level 2 prevalence (77.6%). This could be related to the higher slaughter weight reached by the COX group (P<0.001) and the treatment effect (P<0.01) that probably adds to the effect of live weight. Diet had no effect on overall live performance of VACC-LE plus chickens, which were similar to those of the VACC group.

    Objective: To investigate the prevalence of Helicobacter pylori (Hp) infection in pre-school and school age children with C-14 urea breath test, and to explore its association with age and socioeconomic factors in Turkey. Methods: Hp infection status was determined by using Urea Breath Test (UBT). Patients who had previous gastric surgery, Hp eradication treatment or equivocal UBT results were excluded. A questionnaire was administered to elicit information on gender, age, ABO/Rh blood group type, presence of gastric disease in the family, domestic animal in the household, and treatment for idiopathic Iron Deficiency Anemia (IDA). Results: This retrospective study included 500 pediatric patients (179 boys, 321 girls, mean age 10.7±4.3 years) of whom 62 (12.4%) were aged ≤6 years and 438 (87.6%) were aged 7 to 16 years. Helicobacter pylori (Hp) was positive in 245 (49%) cases. In the pre-school age group, 21/62 cases (34%) had positive UBT while in the school age group 224/438 children (51%) had positive UBT. A family history of dyspepsia and pet ownership were not associated with Hp positivity. Hp positive 76 (29.8%) children were on IDA treatment but this was not statistically significant. Conclusion: The Hp infection positivity rate was 49% in the pediatric age study group. The positivity rate was significantly lower at preschool age than school age, and it increased with age. There was no association with gender, ABO/Rh blood groups, presence of domestic pets, IDA, or history of gastric disease in the family. PMID:26316471

    Background: The studies have shown that metabolic syndrome (MetS) leads to an increase twice as much in cardiovascular diseases (CVD) and four times as much in diabetes mellitus (DM) prevalence since the second half of the 20th century. Aims: This study aims to determine and discuss the prevalence of the MetS and co- factors among individuals at the age of 30 and over in Balcova district of İzmir province according to the American National Cholesterol Education Program - Adult Treatment Panel III (NCEP ATP III) and InternationalDiabetes Federation (IDF) criteria. Study Design: Cross-sectional study. Methods: Data obtained from the Balcova Heart Project in İzmir were used in the study. The dependent variable of the study is MetS existence. The independent variables were socio-demographic characteristics (age, gender, education level, and marital status), self-perceived economic status, physical activity, smoking status, healthy nutrition and body mass index (BMI). Results: The prevalence of MetS was 36.9% according to the diagnostic criteria of IDF, while it was 27.4% according to ATP III criteria. According to the both criteria, increasing age, low education, poor economic status perception, physical inactivity, and obesity increase the risk of MetS. Apart from the IDF criteria, being female and a current smoker increase the risk of the MetS in the NCEP-ATP III. Conclusion: Compared to educational studies of MetS as of today, which are community and health-oriented studies, it is challenging that the prevalence of MetS was found to be high for both criteria in our study. Therefore, in particular, primary health care doctors must be prompted to protect the public against DM and CVD in particular. PMID:27308078

    Objectives Consistent estimation of the burden of chronic obstructive pulmonary disease (COPD) has been hindered by differences in methods, including different spirometric cut-offs for impaired lung function. The impact of different definitions on the prevalence of potential airflow obstruction, and its associations with key risk factors, is evaluated using cross-sectional data from two nationally representative population surveys. Design Pooled cross-sectional analysis of Wave 2 of the UK Household Longitudinal Survey and the Health Survey for England 2010, including 7879 participants, aged 40–95 years, who lived in England and Wales, without diagnosed asthma and with good-quality spirometry data. Potential airflow obstruction was defined using self-reported physician-diagnosed COPD; a fixed threshold (FT) forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC) ratio <0.7 and an age-specific, sex-specific, height-specific and ethnic-specific lower limit of normal (LLN). Standardised questions elicited self-reported information on demography, smoking history, ethnicity, occupation, respiratory symptoms and cardiovascular disease. Results Consistent across definitions, participants classed with obstructed airflow were more likely to be older, currently smoke, have higher pack-years of smoking and be engaged in routine occupations. The prevalence of airflow obstruction was 2.8% (95% CI 2.3% to 3.2%), 22.2% (21.2% to 23.2%) and 13.1% (12.2% to 13.9%) according to diagnosed COPD, FT and LLN, respectively. The gap in prevalence between FT and LLN increased in older age groups. Sex differences in the risk of obstruction, after adjustment for key risk factors, was sensitive to the choice of spirometric cut-off, being significantly higher in men when using FT, compared with no significant difference using LLN. Conclusions Applying FT or LLN spirometric cut-offs gives a different picture of the size and distribution of the disease burden. Longitudinal studies

    Recent literature reviews show that bullying perpetration and victimization are major public health concerns for typically developing (TD) youth. Nevertheless, the magnitude of this phenomenon among youth with intellectual disabilities (ID) remains unclear. Therefore, the purpose of this review is to provide a synthesis of the empirical studies examining the prevalence and correlates of bullying perpetration and victimization among youth with ID. A systematic literature search was performed and 11 studies met the inclusion criteria. The findings from these studies showed weighted mean prevalence rates of general bullying perpetration, bullying victimization and both of 15.1%, 36.3%, and 25.2%, respectively. Weighted mean prevalence rates of bullying perpetration and victimization differed according to the characteristics of the studies (e.g., assessment context, school setting, information source, type of measures, time frame). Additionally, high weighted mean prevalence rates of physical (33.3%), verbal (50.2%), relational (37.4%), and cyber (38.3%) victimization were found among youth with ID. When youth with ID were compared to youth with other disabilities or TD peers, no clear differences were found. Finally, the present review shows that correlates of bullying perpetration and victimization in this population remain understudied.

    Traumatic dental injuries are widespread in the population and the prevalence of traumatic dental injuries among school children in different parts of the world varies from about 3% to 45%. Most injuries involve the anterior teeth, which may lead to eating restrictions, changes in physical appearance, speech defects and psychological impacts that affect the child's quality of life. A cross-sectional survey was carried out to investigate the prevalence, aetiology and types of injuries to permanent incisors among schoolchildren aged 10-14 years from Maseru, Lesotho. Upper and lower permanent incisors were examined for dental injuries. The prevalence of traumatic injuries to the permanent incisor teeth was 9.3% (13.3% boys and 6.3% girls). Significantly more boys than girls suffered injury. The most common type of injury was enamel fractures and most common cause was falls. Health promotion policies should aim to create an appropriate and safe environment for children. Soft playground surfaces, school-crossing patrols, marked zebra crossings and bicycle lanes would help create a safe environment. Speed limits for cars and the use of seat belts, air bags, special car seats for children and bicycle helmets should be enforced. Mouth guards should be used when playing sport, in particular contact sports. Education regarding the epidemiology of dental injuries and their prevention through health promotion may play a major role in reducing the prevalence of dental injury and avoiding the financial costs of treatment, especially in developing countries.

    Intestinal parasite infections are major public health problems of children in developing countries causing undernutrition, anemia, intestinal obstruction and mental and physical growth retardation. This study was conducted to assess the prevalence of intestinal helminthic infections among children under five years of age with emphasis on Schistosoma mansoni in Wonji Shoa Sugar Estate, Ethiopia. A cross-sectional parasitological survey was conducted in under-five children living in Wonji Shoa Sugar Estate Ethiopia, April, 2013. Stool samples were collected and examined for intestinal parasites using single Kato-Katz and single Sodium acetate-acetic acid-formalin (SAF) solution concentration methods. Out of 374 children examined using single Kato-Katz and single SAF-concentration methods, 24.3% were infected with at least one intestinal parasite species. About 10.4%, 8.8%, 4.6%, 2.9%, 1.6% and 0.8% of the children were infected with Hymenolepis nana, Schistosoma mansoni, Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis and hookworm, respectively. Prevalence of double, triple and quadruple intestinal helminthic infection was 6.4%, 0.54% and 1.1%, respectively. A significant increase in prevalence of S. mansoni (8.3% versus 3.2%) and T. trichiura (2.7% versus 0.5%) infection was observed when determined via the single Kato-Katz method compared to the prevalence of the parasites determined via the single SAF-concentration method. On the other hand, the single SAF-concentration method (9.1%) revealed a significantly higher prevalence of H. nana infection than the single Kato-Katz (1.6%) does. In conclusion, intestinal helminths infections particularly S. mansoni and H. nana were prevalent in under-five children of Wonji Shoa Sugar Estate. Including praziquantel treatment in the deworming program as per the World Health Organization guidelines would be vital to reduce the burden of these diseases in areas where S. mansoni and H. nana infections are

    English Bulldogs have been reported to demonstrate abnormal growth and development of the nasal turbinates, which contribute to an increase in airway resistance and hence clinical signs of brachycephalic airway syndrome. The purpose of this prospective, cross-sectional study was to assess the prevalence and severity of caudal aberrant turbinate protrusion via CT studies of English Bulldogs with, according to the owners, none or minimal clinical signs of brachycephalic airway syndrome. An additional objective was to propose a classification scheme for describing the degree of caudal aberrant turbinate protrusion in English Bulldogs and to apply this scheme in assessing the effect of gender, weight, and age on prevalence and severity of turbinate protrusion. The nasal cavities of 40 clinically healthy English Bulldogs were examined. The prevalence of caudal aberrant turbinates in this group was 100%. Using our proposed classification scheme, Grade 1 (minimal) was detected in 7 of 40 (17.5%), Grade 2 (mild) in 28 of 40 (70%), and Grade 3 (moderate) in 5 of 40 (12.5%) English Bulldogs. No significant effect of gender, weight, and age on degree of protrusion was found. In conclusion, this study identified minimal to moderate protrusion of caudal aberrant turbinates toward the nasopharynx in all the sampled English Bulldogs, despite the absence of clinical signs of brachycephalic airway syndrome.

    The purpose of this study was to find the prevalence of low bone health conditions and assess associated nutritional and other risk factors in Indian women aged 41-60 years. A total of 1,911 women participated in this cross-sectional study. Bone health was assessed using an Omnisense multisite quantitative ultrasound bone densitometer on two sites (radius and tibia). Crude prevalence of osteopenia and osteoporosis was found to be 30.09% and 19.89%, respectively. The Indian women were deficient in a majority of nutrients. Postmenopause, hysterectomy, hyperthyroid, hypothyroid, hypertension, low physical activity, low sun exposure, high stress levels, and low calcium levels were found to be independent risk factors of low bone health.

    This paper discusses the effect that high altitudes have on iron metabolism and summarizes the results of an iron-folate supplementation trial. The two main objectives of the trial were to determine hemoglobin cut-off values for the diagnosis of anemia in Bolivian women of childbearing age living at high altitudes, and to estimate the prevalence of anemia in this population. The study showed that nutritional anemia is an important public health problem in such populations and that many methods of assessing it lead to an underestimation of prevalence. The cut-off values defined through this study, one of the few iron supplementation trials conducted at high altitudes, confirm the need to establish revised hemoglobin values for the diagnosis of anemia in populations living at high altitudes.

    Objective: to examine the clinical evidence reporting the prevalence of sarcopenia and the effect of nutrition and exercise interventions from studies using the consensus definition of sarcopenia proposed by the European Working Group on Sarcopenia in Older People (EWGSOP). Methods: PubMed and Dialog databases were searched (January 2000–October 2013) using pre-defined search terms. Prevalence studies and intervention studies investigating muscle mass plus strength or function outcome measures using the EWGSOP definition of sarcopenia, in well-defined populations of adults aged ≥50 years were selected. Results: prevalence of sarcopenia was, with regional and age-related variations, 1–29% in community-dwelling populations, 14–33% in long-term care populations and 10% in the only acute hospital-care population examined. Moderate quality evidence suggests that exercise interventions improve muscle strength and physical performance. The results of nutrition interventions are equivocal due to the low number of studies and heterogeneous study design. Essential amino acid (EAA) supplements, including ∼2.5 g of leucine, and β-hydroxy β-methylbutyric acid (HMB) supplements, show some effects in improving muscle mass and function parameters. Protein supplements have not shown consistent benefits on muscle mass and function. Conclusion: prevalence of sarcopenia is substantial in most geriatric settings. Well-designed, standardised studies evaluating exercise or nutrition interventions are needed before treatment guidelines can be developed. Physicians should screen for sarcopenia in both community and geriatric settings, with diagnosis based on muscle mass and function. Supervised resistance exercise is recommended for individuals with sarcopenia. EAA (with leucine) and HMB may improve muscle outcomes. PMID:25241753

    A greenhouse study was carried out using three durum wheat (Triticum durum Desf.) cultivars differing in their field performances under arid conditions (Kabir 1, poor yield stability; Omrabi 5, high yield stability and Haurani, landrace well adapted to drought). Water stress was imposed by withholding water at the seedling stage. Water potential (Psi(w)), relative water content (RWC), stomatal resistance (SR), and changes in solute concentrations were quantified: (1) as a function of leaf development during the stress period; and (2) in young expanded and growing leaves harvested at the end of the stress treatment. Psi(w), RWC and SR were almost unaffected by leaf age in controls. In contrast, solute concentrations appeared to vary in the course of leaf development. During the stress treatment, Psi(w) and RWC decreased and SR increased in all cultivars; the changes were most often largest in Omrabi 5, lowest in Haurani and intermediate in Kabir 1. Water stress also increased sugar and proline concentrations and decreased nitrate levels. Young expanded and growing leaves differed in terms of Psi(w), RWC and osmotic adjustment (OA). The capacity of OA was greater in growing than in expanded leaves, especially in the two cultivars best adapted to aridity, and allowed turgor maintenance in these genotypes. Sugars were the main solutes that contributed to OA particularly in growing leaves followed by proline and then quaternary ammonium compounds. The contributions of these organic solutes to OA tended to be higher in Omrabi 5 and in Haurani than in Kabir 1. Inorganic solutes, however, did not seem to play an important role in OA despite their high proportion in total solutes.

    Low body weight is an established risk factor for osteoporosis and fracture, but the skeletal risks of higher adiposity are unclear and appear sex-specific and site-dependent. The aim of this study was to investigate associations of total fat mass (TFM), visceral adipose tissue (VAT), and C-reactive protein (CRP) with bone mineral density (BMD) and prevalent vertebral fracture (VF) in men and women aged 62 years. A total of 352 men and women aged 62.5 ± 0.5 years from the Newcastle Thousand Families Study cohort received dual-energy X-ray absorptiometry (DXA) evaluations of femoral neck and lumbar spine BMD, of the lateral spine for vertebral fracture assessment, and of the whole body for TFM and VAT (GE Lunar CoreScan, Madison, WI, USA). Plasma CRP, FRAX scores, falls in the last 12 months, and occupation at age 50 years were also included in the analysis. Vertebral fractures were less prevalent in women than in men (odds ratio [OR] = 0.33, p < 0.001) and BMD or FRAX scores did not differ between participants with and without VF. Women with VF were heavier and had higher TFM, VAT, and CRP than women without (p < 0.001). In women, greater (+1 SD) TFM and VAT increased the odds of any grade VF (TFM: OR = 1.06, p = 0.001; VAT: OR = 2.50, p = 0.002), and greater VAT mass increased the odds of prevalent mild VF (OR = 2.60, p = 0.002). In contrast, there were no associations in men. In both sexes, after controlling for body weight, neither VAT nor CRP were associated with BMD. In conclusion, irrespective of BMD, total and visceral adiposity were associated with prevalent VF in women but not in men. High fat mass, particularly if visceral, should be considered when assessing VF risk in women. Risk factors for VF in men require further investigation, particularly given their high prevalence. © 2017 American Society for Bone and Mineral Research.

    Background. Although pain is experienced among people of all ages, there is a need to study its risk factors and impact among older adults. Aims. The study sought to determine the prevalence, sociodemographics, and clinical correlates of pain along with association of pain with disability among older adults in Singapore. Methods. The WiSE study was a comprehensive cross-sectional, single phase, epidemiological survey conducted among the elderly aged 60 years and above and used a nationally representative sample of three main ethnic groups in Singapore: Chinese, Malays, and Indians. The survey administered 10/66 protocol pain questionnaire, sociodemographic questionnaire, health status questionnaire, World Health Organization Disability Assessment Scale (WHODAS 2.0), and Geriatric Mental State (GMS) examination. Results. A total of 2565 respondents completed the study giving a response rate of 65.5%. The prevalence of pain among the elderly aged 60 years and above is 19.5 %. Females, incomplete primary education Indians, and those diagnosed with any chronic health condition were associated with risk of pain and disability. Conclusion. Study findings showed that disability related to pain among the elderly is considerable making it a priority to reduce the morbidity and disability among the elderly with pain. PMID:27445628

    Purpose We estimate trends in the prevalence of urinary incontinence in the adult population of the United States from 2001 through 2008 before and after adjusting for other potential associated factors. Materials and Methods We analyzed data on 17,850 adults 20 years old or older who participated in the 2001 to 2008 cycles of the National Health and Nutrition Examination Survey. Any urinary incontinence was defined as a positive response to questions on urine leakage during physical activity, before reaching the toilet and during nonphysical activity. During this period changes in demographic and clinical factors associated with urinary incontinence included age, race/ethnicity, obesity, diabetes and chronic medical conditions (prostate disease in men). Age standardized prevalence estimates and prevalence ORs of urinary incontinence trends were determined using adjusted multivariate models with appropriate sampling weights. Results The age standardized prevalence of urinary incontinence in the combined surveys was 51.1% in women and 13.9% in men. Prevalence in women increased from 49.5% in 2001 to 2002, to 53.4% in 2007 to 2008 (Ptrend = 0.01) and in men from 11.5% to 15.1%, respectively (Ptrend = 0.01). In women increased prevalence was partially explained by differences in age, race/ethnicity, obesity, diabetes and select chronic diseases across the survey periods. After adjustment the prevalence OR for 2007 to 2008 vs 2001 to 2002 decreased from 1.22 (95% CI 1.03–1.45) to 1.16 (95% CI 0.99–1.37). in men adjustment for potentially associated factors did not explain the increasing prevalence of urinary incontinence. Conclusions The age standardized prevalence of urinary incontinence increased in men and women from 2001 through 2008. Decreasing obesity and diabetes may lessen the burden of urinary incontinence, especially in women. PMID:21684555

    Objectives The impact of gender and age on the association between sleep duration and hypertension is not well known in Asians. The objective of this study was to analyse gender- and age-specific associations between sleep duration and prevalent hypertension in middle-aged and elderly Chinese. Design Secondary analysis of a cohort sample. Setting This study used data from the national baseline survey of the China Health and Retirement Longitudinal Study (CHARLS, 2011–2012), covering 150 counties/districts and 450 villages/resident committees from 28 provinces in China. Participants Community-based subjects were drawn from the CHARLS through multistage probability sampling. Overall, this study included 9086 eligible subjects aged 45 years or above. Outcome measures Self-reported sleep duration was obtained using a structured questionnaire. The mean of three measures of systolic blood pressure and diastolic blood pressure was calculated. By gender and age groups (45–60 years, middle-aged; ≥60 years, elderly), relationships between self-reported sleep duration and prevalent hypertension were examined using logistic regression models to estimate OR and 95% CIs. Results Compared with the reference group (≥7 and <8 hours/night), the group who had less sleep (<6 hours/night) had a higher likelihood of hypertension in the whole sample (OR 1.26, 95% CI 1.04 to 1.52). Significant ORs (95% CIs) of hypertension were 1.68 (1.17 to 2.42), 1.69 (1.11 to 2.59) and 2.21 (1.29 to 3.80) for <6, 6–7 (≥6 and <7) and 8–9 (≥8 and <9) hours/night, respectively, in middle-aged men but not women. Interestingly, a significant association was observed between long sleep duration (≥9 hours/night) and hypertension in middle-aged women (OR 1.55, 95% CI 1.02 to 2.35) but not in men. Conclusions Extremes of sleep duration increased the likelihood of prevalent hypertension in middle-aged Chinese depending on gender, suggesting that appropriate strategies for

    Background We estimated the prevalence of irritable bowel syndrome (IBS) and its impact on patient-reported health-related quality of life (HR-QOL) in a university-based population aged between 18 and 30 years in Bogotá, Colombia. Methods The study had a cross-sectional design. Students, faculty, and staff aged 18-30 years of the Pontificia Universidad Javeriana, Bogotá, Colombia were randomly selected and invited to complete an electronic survey containing the Rome III IBS diagnostic questionnaire and an IBS-specific HR-QOL instrument (IBS-QOL). Results A total of 1082 individuals participated in this study. The prevalence of IBS was 24.0% (95% CI 21.3-26.6%). IBS-constipation was the most common subtype (41.9%; 95% CI 35.5-48.4%). The overall IBS-QOL score indicated HR-QOL impairment (72.1/100). IBS-unsubtyped patients had the highest overall HR-QOL (constipation: 70.6; diarrhea: 67.2; mixed: 67.0; unsubtyped: 77.8; P=0.003). IBS non-consulters had higher IBS-QOL “Food Avoidance” scores than IBS consulters (60.3 vs. 45.5; P=0.002). Conclusion IBS is a prevalent disorder in a university-based population aged 18-30 years and has a significant impact on HR-QOL. IBS-unsubtyped subjects had the highest HR-QOL compared to other subtypes. Food avoidance appears to be a key factor in seeking consultation. PMID:28042240

    Background. Differences in epidemiology of kidney disease across the Middle East may arise from variations in indication for biopsy, environmental exposure and socio-economic status. The Lebanese population is composed of different ethnicities, with distinct ancestry and religion, enabling comparison of their effect on the prevalence of kidney disease within a confined geographic setting and uniform practices. Here we report 5 years’ detailed epidemiology of renal diseases, based on histological diagnosis, in a sample from three large pathology centres in Lebanon. Methods. Records of renal biopsies analysed at the American University of Beirut Medical Center, Hotel Dieu de France Hospital and the Institut National de Pathologie from January 2003 till December 2007 were retrospectively examined. We recorded the following data for each patient: age, gender, indication for renal biopsy and histopathological diagnosis. Religious affiliation and parents’ consanguinity were recorded when feasible. Results. The mean age at renal biopsy was 36.76 ± 20 years (range 1–84). The most common diagnosis was mesangioproliferative glomerulonephritis (GN; 20%), followed by focal segmental glomerulosclerosis (13.2%). While there were no differences in age, gender or indications for biopsy among different religious affiliations, mesangioproliferative GN was significantly more frequent among Muslims (P = 0.039) and offspring of consanguineous unions (P = 0.036). On the other hand, focal segmental glomerulosclerosis was most prevalent in Christians (P < 0.001). Conclusions. Variation in the distribution of diagnoses between Muslim and Christian groups likely reflects differences in population structure and ancestry.

    Spine fracture prevalence is similar in men and women, increasing from <5 % in those <60 to 11 % in those 70-79 and 18 % in those ≥80 years. Prevalence was higher with age, lower bone mineral density (BMD), and in those meeting criteria for spine imaging. Most subjects with spine fractures were unaware of them.

    Infection with the Torque teno sus virus (TTSuV) is believed to be common yet limited information is available on the epidemiology of TTSuV. The objectives of this study were to develop novel and improve existing diagnostic methods for TTSuV infection and to investigate the prevalence of TTSuV species 1 (TTSuV1) and 2 (TTSuV2) in the USA. Three hundred and four blood or fetal thoracic fluid samples were collected from pigs on 40 US farms in 12 States. Samples were collected from fetuses and in pre-suckle neonates (n=73), suckling pigs (1-20 days of age; n=27), nursery pigs (21-55 days of age; n=60), finisher pigs (8-25 weeks of age; n=90) and adults (>25 weeks of age; n=54). Samples were tested by a new quantitative differential real-time PCR for TTSuV1 and TTSuV2 DNA and by ELISA for detection of anti-TTSuV2-antibodies. The prevalence of TTSuV1 DNA ranged from 8.2% (fetuses and neonates) to 81% (finisher pigs) and the prevalence of TTSuV2 DNA ranged from 3.7% (suckling pigs) to 67% (finisher pigs). Evidence of fetal TTSuV infection was minimal. Mixed infection of TTSuV1 and TTSuV2 was seen in 6.7% of the nursery pigs, 52.2% of the finisher pigs, and 22.2% of the mature pigs. The prevalence of TTSuV1 was higher than that of TTSuV2. Anti-TTSuV2 antibodies were not detected in the fetuses and neonates and the seroprevalence of TTSuV2 was between 3.8% and 100% in growing pigs. The results of this study indicate that vertical transmission may not be a main route of TTSuV transmission in pigs in the USA.

    A 2014 U.S. Department of Justice Best Practices Report advocates that states eliminate HIV-specific criminal penalties except under 2 conditions: when a human immunodeficiency virus (HIV)-positive person intentionally commits a sex crime or transmits the virus by engaging in behavior that poses a significant risk of transmission, regardless of actual transmission. We assess the premise of these exceptions to understand whether these best practices are based on scientific evidence about the population at risk of infection and the risk of sexual violence by HIV-positive individuals. We employ nationally representative, cross-sectional survey data from the Current Population Survey (CPS), the Survey of Inmates in State, Federal, and Local Jails (SISFLJ), and the National Health and Nutrition Survey (NHANES). Data from the CPS, SISFLJ, and NHANES are weighted and combined to analyze bias in the population at risk of HIV. Linear probability models are employed to estimate the likelihood that HIV-positive inmates are incarcerated for violent or sexual offenses, net of socioeconomic factors. We find significant measurement bias in HIV prevalence rates. The selection of national surveys for population denominators distorts contemporary estimates of HIV prevalence by 7% to 20%. Our findings also illustrate that HIV-positive inmates are 10 percentage-points less likely to be incarcerated for violent offenses than HIV-negative inmates. National best practice guidelines may undermine effective social policy that aims to curtail stigma within HIV-positive communities because scientific evidence neither include inmates into prevalence denominators (as a measure of the population at risk) nor assess the likelihood that HIV-positive inmates commit violent or sexual crimes.

    Context Limited data exist about blood lead levels and potential exposures among children living in Puerto Rico. The Puerto Rico Department of Health has no formal blood lead surveillance program. Objectives We assessed the prevalence of elevated BLLs [≥ 5 micrograms (μg) of lead per deciliter (dL) of blood], household environmental lead levels, and risk factors for BLL among children less than 6 years old living in Puerto Rico in 2010. Methods We used a population-based cross-sectional sampling strategy to enroll an island-representative sample of Puerto Rican children less than 6 years old. We estimate the island-wide weighted prevalence of elevated BLL, and conducted bivariable and multivariable linear regression analyses to ascertain risk factors for elevated BLLs. Results The analytic dataset included 363 households and 439 children less than 6 years old throughout Puerto Rico. The weighted geometric mean BLL of children less than 6 years old was 1.57 μg/dL [95% confidence interval (CI) = 1.27, 1.88). The weighted prevalence of children less than 6 years old with BLLs ≥ 5 μg/dL was 3.18% (95% CI = 0.93, 5.43) and for BLLs ≥ 10 μg/dL was 0.50% (95% CI = 0, 1.31). Higher mean BLLs were significantly associated with data collection during the summer months, a lead-related activity or hobby of anyone in the residence and maternal education less than 12 years. Few environmental lead hazards were identified. Conclusions The prevalence of elevated BLLs among Puerto Rican children less than 6 years old is comparable to the most recent (2007 – 2010) U.S. national estimate [BLLs ≥ 5 μg/dL = 2.6% (95% CI = 1.6, 4.0)]. Our findings suggest targeted screening of specific higher-risk groups of children less than 6 years old can replace island-wide or insurance specific policies of mandatory blood lead testing in Puerto Rico.

    Studies on epidemiology of female sexual problems consistently indicate high prevalence rates worldwide, suggesting that this clinical presentation should be considered as a public health concern. However, there are no published studies on prevalence of sexual problems in Portugal. The present study investigated the prevalence, severity, and comorbidity of female sexual problems in a Portuguese community sample. In addition, the authors assessed the role of sociodemographic predictors of women's sexual difficulties. The authors recruited 500 women using quota methods to resemble the Portuguese population according to its demographic characteristics. Participants answered to the Female Sexual Function Index and to a sociodemographic questionnaire. Findings indicated that 37.9% of the Portuguese women reported symptoms of sexual problems. Symptoms of lack of sexual desire was the most frequent sexual difficulty with 25.4% of the women reporting low desire most times or always, followed by symptoms of orgasmic (16.8%), sexual arousal (15.1%), and lubrication difficulties (12.9%), dyspareunia (9.8%), and vaginismus (6.6%). Results indicated that age was a significant predictor of female sexual problems. Results also indicated that symptoms of female sexual problems are a significant health concern in Portugal, suggesting that public policies should be developed to promote sexual health.

  15. Prevalence of non-communicable diseases in Brazilian children: follow-up at school age of two Brazilian birth cohorts of the 1990's

    2011-01-01

    Background Few cohort studies have been conducted in low and middle-income countries to investigate non-communicable diseases among school-aged children. This article aims to describe the methodology of two birth cohorts, started in 1994 in Ribeirão Preto (RP), a more developed city, and in 1997/98 in São Luís (SL), a less developed town. Methods Prevalences of some non-communicable diseases during the first follow-up of these cohorts were estimated and compared. Data on singleton live births were obtained at birth (2858 in RP and 2443 in SL). The follow-up at school age was conducted in RP in 2004/05, when the children were 9-11 years old and in SL in 2005/06, when the children were 7-9 years old. Follow-up rates were 68.7% in RP (790 included) and 72.7% in SL (673 participants). The groups of low (<2500 g) and high (≥ 4250 g) birthweight were oversampled and estimates were corrected by weighting. Results In the more developed city there was a higher percentage of non-nutritive sucking habits (69.1% vs 47.9%), lifetime bottle use (89.6% vs 68.3%), higher prevalence of primary headache in the last 15 days (27.9% vs 13.0%), higher positive skin tests for allergens (44.3% vs 25.3%) and higher prevalence of overweight (18.2% vs 3.6%), obesity (9.5% vs 1.8%) and hypertension (10.9% vs 4.6%). In the less developed city there was a larger percentage of children with below average cognitive function (28.9% vs 12.2%), mental health problems (47.4% vs 38.4%), depression (21.6% vs 6.0%) and underweight (5.8% vs 3.6%). There was no difference in the prevalence of bruxism, recurrent abdominal pain, asthma and bronchial hyperresponsiveness between cities. Conclusions Some non-communicable diseases were highly prevalent, especially in the more developed city. Some high rates suggest that the burden of non-communicable diseases will be high in the future, especially mental health problems. PMID:21693042

    Background Sleep disorders causes a significant negative effect on mental and physical health, particularly among the elderly. The disease burden and risk factors of poor sleep quality of the elderly need to be verified using a validated form of measurement in urban mainland China. Methods This study included 1086 community residents aged ≥60 years who completed the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI). Poor sleeper was defined by a CPSQI global score of >5. Subjects also accepted the neurological and neuropsychological assessments, including the Mini-Mental State Examination, Center for Epidemiological Studies Depression Scale, and Zung Self-Rating Anxiety Scale (ZSAS). A history of chronic diseases was confirmed by the medical records of each participant. Results The prevalence of poor sleep quality in this population was 41.5% (95% confidence interval (CI) = 38.6–44.5%), with a higher rate observed in elderly females (45.8% [95% CI = 41.9–49.7%]) than that in elderly males (35.8% [95% CI = 31.4–40.1%]). The prevalence rate increased with age, from 32.1% (95% CI = 27.8–36.4%) in those aged 60–69 years to 52.5% (95% CI = 45.9–59.1%) in those aged ≥80 years (p value for trend<0.001). Multivariate logistic regression analysis indicated that age (OR = 1.03[95% CI = 1.01–1.05], p<0.001), less education duration (OR = 1.04 [95% CI = 1.01–1.08, p = 0.014), living alone (OR = 1.62 [95% CI = 1.02–2.58], p = 0.04), anxiety (ZSAS score: OR = 1.09 [95% CI = 1.05–1.12], p<0.001), number of chronic disease (OR = 1.18 [95% CI = 1.07–1.30], p = 0.14) and arthritis (OR = 1.45[95% CI = 1.05–2.01], p = 0.025) were risk factors of poor sleep quality. Conclusions Poor sleep quality is highly prevalent among elderly Chinese residents in urban Shanghai.

    Background Comorbid mental health problems have been shown to have an adverse effect on the quality of life of people with common eye disorders. This study aims to assess whether symptoms of anxiety and/or depression are more prevalent in people with age-related macular degeneration (AMD) than in people without this condition. Methods A systematic search of electronic databases (Medline, CINAHL, EMBASE, PsycINFO) from inception to February 2012 was conducted to identify studies of AMD populations which measured symptoms of anxiety and/or depression. Reference checking of relevant articles was also performed. Data on the study setting, prevalence and how anxiety and depression were measured were extracted from the papers. Critical appraisal was performed using the Critical Appraisal Skills Programme (CASP) tools. Results A total of 16 papers were included in the review, from an original search result of 597. The prevalence estimates, taken from nine cross-sectional and cohort studies, ranged from 15.7%-44% for depressive symptoms and 9.6%-30.1% for anxiety symptoms in people with AMD. The seven case–control studies found that people with AMD were more likely to experience symptoms of depression compared with those without AMD, but not more likely to experience symptoms of anxiety. Conclusions Overall, the evidence suggests that symptoms of depression are more prevalent amongst AMD populations than anxiety symptoms. The heterogeneity of the studies included in this review means that it is difficult to draw strong conclusions as to the true estimates of depression and anxiety symptoms in AMD populations and prevented formal meta-analysis. Further research which specifies clinical anxiety and gives clear definitions as to the type of AMD being investigated is required. PMID:24923726

    Among inherited risk factors for venous thrombosis, the most common are the FV-G1691A and FII-G20210A polymorphisms. The FV-G1691A polymorphism is preferentially observed in Europe, with differences between European countries. The FII-G20210A polymorphism is observed all over the world. The study was designed to compare the prevalence of the FV-G1691A and FII-G20210A polymorphisms in a large French population of unrelated individuals with no thrombotic disease history and to determine the age and geographical distributions. Over a period of 18 months, 6154 individuals were included throughout France and FV-G1691A and FII-G20210A polymorphisms were determined. The FV-G1691A prevalence was 3.84% (95% confidence interval 3.35-4.33) and the FII-G20210A prevalence was 3.07% (95% CI 2.63-3.51). A north-east/south-west gradient was observed in the FV-G1691A geographical distribution. No difference was observed in the geographical distribution of FII-G20210A polymorphism nor in the age distribution of the two polymorphisms. The prevalence of the two polymorphisms was similar whatever the blood group (O or non-O). Plasma D-dimers were significantly higher in healthy individuals with FV-G1691A but not in individuals with FII-G20210A. Thirty percent of variation in plasma prothrombin level was explained by environmental factors (serum cholesterol, age, oral contraception, hormonal replacement therapy, body mass index, sex) and genetic factors (FII-G20210A). As expected, individuals with FII-G20210A displayed higher plasma prothrombin level compared with individuals with wild type. However, this was not associated with a modification of the fibrin clot elastic modulus. This study shows a differential distribution of the two polymorphisms among the French territory. These polymorphisms confer a very mild hypercoagulable state as shown by the limited increased in basal D-dimers in mutated FV-G1691A populations and only a trend that does not reach statistical significance for FII

    Background To determine the correlates and the prevalence of infertility in a group of women. Materials and Methods This cross-sectional study was carried out on 570 subjects aged 18-49 years in a town of western Turkey between July and August 2012. Women who have inability to become pregnant despite regular sexual intercourse during the last year were considered to be infertile. UCLA Loneliness Scale was used to assess the severity of loneliness. The data were analyzed by Kruskal-Wallis, Mann Whitney U and Chi-square tests. Results The mean age of the participants was 35.48 ± 8.39 years. The frequency of the infertility in our study was 12.8% (n=73). The prevalence of infertility was higher in those with a history of gynecological disease or gynecologic surgery and in those with menstrual irregularity (p<0.05; for each). The mean score on the UCLA Loneliness Scale was 32.16 ± 9.49 (from 20 to 70). In this study, no difference was found between the level of loneliness and who is responsible for infertility among infertile/fertile women (p≥0.05). Level of loneliness among the women with primary infertility was higher compared to the women with secondary infertility (p<0.05). Conclusion The prevalence of infertility among the women was relatively high. It was concluded that prospective studies are needed in order to expose the relationship between the infertility and the level of loneliness in women. PMID:25083180

    The aim was to study time trends in prevalence of disability in ADL and survival among men and women 78 years and older comparing two cohorts. The study was a time trend study based on two population-based community cohorts, the Nordanstig Project (NP), collected 1995-1998 and the Swedish National Study on Aging and Care in Nordanstig (SNAC-N), collected 2001-2003. The participants were people aged 78 years and older from the NP cohort (N=303) and from the SNAC-N cohort (N=406). All were clinically examined by physicians and nurses using standardized protocols. Disability was defined as a need for assistance in one or more ADL activities. The prevalence of disability and survival were compared using logistic and Cox models. The prevalence of ADL disability was stable for men, while women became more disabled in ADL during the time period, OR 2.36 (1.12-4.94). There was no significant difference in survival time between the cohorts in either ADL disabled persons or non-disabled persons. There was a tendency for increased survival for non-disabled persons in SNAC-N compared with NP, although not significant; this was particularly true for women. In general, women survived longer than men did regardless of whether they were ADL disabled or not. The time trends for ADL disability found in the study show that ADL disability had increased in women but not in men. More studies are needed to identify risk factors for ADL disability with a view to preventing it in time.

    Research on the epidemiology of monoclonal gammopathy of undetermined significance (MGUS) is limited in Korea. The aim of this study was to determine the prevalence and characteristics of MGUS in an elderly urban Korean population. A random sample of 1118 Korean elders was selected from residents aged 65 years or older living in Seongnam, Korea 1 year from August 2005. We obtained plasma samples remaining after scheduled tests for the Korean Longitudinal Study on Health and Aging. The mean age of the study population was 72 years (range, 65-97 years). To screen for MGUS, immunofixation and free light-chain (FLC) assays were performed. Age-adjusted and gender-adjusted MGUS prevalence rates in 680 responders were estimated as 3.3% [95% confidence interval (CI) = 2.0-4.6%], and the estimated age-adjusted prevalence of MGUS was 4.3% in men (95% CI = 1.9-6.6%) and 2.6% in women (95% CI = 1.0-4.2%). Abnormal FLC ratios were detected in 10% of MGUS cases. Multivariate analysis of 945 participants revealed that significant risk factors for MGUS included advanced age, male sex, hyperproteinemia, increased erythrocyte sedimentation rate, and abnormal FLC ratio. MGUS is less prevalent among elderly Koreans (3.3%) than other races. This is the first study to estimate the prevalence of MGUS in the Korean elderly population. Our findings should be confirmed with additional studies analyzing follow-up samples from 2010.

    Thalassemia is the name of a group of genetic, inherited disorders of the blood. More specifically, it is a disorder of the hemoglobin molecule inside the red blood cells. According to World health Organization (WHO), there are about 3% beta-thalassemia carrier and about 4% Hb E/beta-thalassemia carrier in Bangladesh. Our objective is to identify the prevalence of beta-thalassemia in our adolescent populations and to review risk factors that would most easily identify a subset of adolescent patients at greatest risk for the development of beta-thalassemia. We also made a study of clinical profile of 53 thalassemic patients, observing the relationship between the patients with their verity ages and sex. The cases are taken on the basis of their age (2-30 years), beta-thalassemia major, clinical jaundice with history of chronic blood transfusion. The cases excluded those who had jaundice due to viral hepatitis or hepatitis due to heavy metal poisoning (Arsenic) and those with spleenectomy. Liver function test has been evaluated in 53 patients. That were recorded with some relevant demographical data such as age, sex, blood group where median age was of 16 years and mean (±SD) age 15.4151 ± 7.90918. Among them were 21 (39.6%) female and 32 (60.4%) male. With an average 15.1% (8 in no.) beta-thalassemia, 7.5% (4 in no.) beta-thalassemia major and 77.4% (41 in no.) E-beta-thalassemia cases have been found in the study. Mean (±SD) TSB in total 53 subjects with age group 2-10 years and 21-30 years is significant. The study revealed that in thalassemic patients when the age is more, the disease progresses with their complication. Hepatic complication is mainly due to being hepatocellular in nature than that of obstructive one. PMID:24826050

    Objectives To estimate the prevalence of spirometry-defined airflow obstruction among ever-employed US adults. Methods Data from the 2007 to 2010 National Health and Nutrition Examination Survey (NHANES) for adults 18–79 years with valid spirometry and longest held occupation were analysed. The age-standardised prevalence of spirometry-defined airflow obstruction was estimated overall and by smoking status. Results Age-standardised prevalence of airflow obstruction was 13.7% (95% CI 12.4% to 15.0%) and was highest in participants aged 60–79 years (17.4%, 95% CI 15.2% to 19.6%), males (14.8%, 95% CI 12.0% to 17.6%), non-Hispanic whites (15.4%, 95% CI 13.8% to 16.7%) and ever smokers (19.1%, 95% CI 16.6% to 21.5%). Age-standardised prevalence of airflow obstruction was >20% for installation, maintenance and repair occupations (p=22.1%, 95% CI 16.5% to 27.8%), and for construction and extraction occupations (20.7%, 95% CI 13.5% to 27.9%). Conclusions Prevalence of airflow obstruction varied by demographic characteristics and occupational factors with a higher prevalence among ever smokers for most demographic characteristics and occupational factors. Study findings emphasise the importance of monitoring the lung function of workers in occupations with a high prevalence of airflow obstruction. PMID:27152013

    Public health nutritionists rely on anthropometry for nutritional assessment, program planning, and evaluation. Children are usually heavily clothed at high altitudes and in cold climates. Failing to adjust for clothing weight could underestimate malnutrition prevalence. The objective of this paper is to validate an adjustment process for estimating clothing weight and quantify potential misclassification error. In March and September 2009, 293 and 272 children under 2 years of age, respectively, were measured for weight and length in 14 highlands communities in Ecuador. Weight-for-age z-scores (WAZ) and weight-for-height z-scores (WHZ) were compared using clothing-unadjusted weights and two types of clothing-adjusted weights: individual clothing-weights and population-mean clothing-weights. Modelling showed up to 24% of children's nutritional status and degree of malnutrition were misclassified for WAZ, and 13% for WHZ, when clothing was not taken into account in this cold climate. Compared with the more time-intensive individual clothing-weight adjustment, the population-mean clothing-weight adjustments had high specificity and sensitivity for WAZ. In cold climates, adjusting for population mean clothing weight provides a better estimate of the prevalence of malnutrition to inform appropriate program decisions for addressing underweight. An individual clothing weight adjustment may also be essential to classify a specific child's nutritional status when acute malnutrition is a concern.

    We analyse the stellar populations in the host galaxies of 53 X-ray selected optically dull active galactic nuclei (AGN) at 0.34 < z < 1.07 with ultradeep (mAB = 26.5, 3σ) optical medium-band (R ˜ 50) photometry from the Survey for High-z Absorption Red and Dead Sources (SHARDS). The spectral resolution of SHARDS allows us to consistently measure the strength of the 4000 Å break, Dn(4000), a reliable age indicator for stellar populations. We confirm that most X-ray selected moderate-luminosity AGN (LX < 1044 erg s-1) are hosted by massive galaxies (typically M* >1010.5 M⊙) and that the observed fraction of galaxies hosting an AGN increases with the stellar mass. A careful selection of random control samples of inactive galaxies allows us to remove the stellar mass and redshift dependences of the AGN fraction to explore trends with several stellar age indicators. We find no significant differences in the distribution of the rest-frame U - V colour for AGN hosts and inactive galaxies, in agreement with previous results. However, we find significantly shallower 4000 Å breaks in AGN hosts, indicative of younger stellar populations. With the help of a model-independent determination of the extinction, we obtain extinction-corrected U - V colours and light-weighted average stellar ages. We find that AGN hosts have younger stellar populations and higher extinction compared to inactive galaxies with the same stellar mass and at the same redshift. We find a highly significant excess of AGN hosts with Dn(4000) ˜ 1.4 and light-weighted average stellar ages of 300-500 Myr, as well as a deficit of AGN in intrinsic red galaxies. We interpret failure in recognizing these trends in previous studies as a consequence of the balancing effect in observed colours of the age-extinction degeneracy.

    Introduction Despite increasing demand for clinical interventions into sexual problems in an aging population, epidemiological data on the subject are scarce. Aims To examine the prevalence of sexual problems across different sociodemographic groups, and risk factors for these problems in multiple domains of life. Methods Statistical analysis of data from the 2005–2006 National Social Life, Health, and Aging Project (NSHAP), a nationally representative U.S. probability sample of 1,550 women and 1,455 men aged 57–85 at the time of interview. Main Outcome Measures Likelihood of experiencing sexual dysfunction in the preceding 12 months. Results Sexual problems among the elderly are not an inevitable consequence of aging, but instead are responses to the presence of stressors in multiple life domains. This impact may partly be gender differentiated, with older women's sexual health more sensitive to their physical health than is true for men. The mechanism linking life stress with sexual problems is likely to be poor mental health and relationship dissatisfaction. The NSHAP results demonstrate the consistent impact of poor mental health on women's reports of sexual problems and the less consistent association with men's problems. Conclusions The results point to a need for physicians who are treating older adults experiencing sexual problems to take into account not simply their physical health, but also their psychosocial health and satisfaction with their intimate relationship.

    Background This study describes the prevalence of dementia and major dementia subtypes in Spanish elderly. Methods We identified screening surveys, both published and unpublished, in Spanish populations, which fulfilled specific quality criteria and targeted prevalence of dementia in populations aged 70 years and above. Surveys covering 13 geographically different populations were selected (prevalence period: 1990-2008). Authors of original surveys provided methodological details of their studies through a systematic questionnaire and also raw age-specific data. Prevalence data were compared using direct adjustment and logistic regression. Results The reanalyzed study population (aged 70 year and above) was composed of Central and North-Eastern Spanish sub-populations obtained from 9 surveys and totaled 12,232 persons and 1,194 cases of dementia (707 of Alzheimer's disease, 238 of vascular dementia). Results showed high variation in age- and sex-specific prevalence across studies. The reanalyzed prevalence of dementia was significantly higher in women; increased with age, particularly for Alzheimer's disease; and displayed a significant geographical variation among men. Prevalence was lowest in surveys reporting participation below 85%, studies referred to urban-mixed populations and populations diagnosed by psychiatrists. Conclusion Prevalence of dementia and Alzheimer's disease in Central and North-Eastern Spain is higher in females, increases with age, and displays considerable geographic variation that may be method-related. People suffering from dementia and Alzheimer's disease in Spain may approach 600,000 and 400,000 respectively. However, existing studies may not be completely appropriate to infer prevalence of dementia and its subtypes in Spain until surveys in Southern Spain are conducted. PMID:19840375

    In a survey of 1,439 female college students, 24% reported that they had what they considered consensual sexual intercourse between ages 13 and 15 (2% at age 13, 7% at age 14, and 15% at age 15). Contrary to the impression left by studies of teenage mothers, the majority of their male sexual partners were not substantially older than them but instead were more typically "somewhat older" (2-4 years apart) or similar aged (less than 2 years apart). The percentage of "much older" partners (5 or more years older) was 31% for those who had intercourse at age 13, 17% for those who had intercourse at age 14, and 13% for those who had intercourse at age 15. Women who had intercourse at age 13 endorsed more current symptoms of psychological distress than those who first had intercourse at age 14 or 15. There were no significant differences between the groups in current levels of sexual satisfaction. Partner's age difference was not significantly associated with current levels of either psychological distress or sexual satisfaction. The implications of these results were discussed in light of recent calls in the United States for more strict and rigorous enforcement of statutory rape laws.

    People who inject drugs (PWID) are at high risk for blood-borne pathogens transmitted during the sharing of contaminated injection equipment, particularly hepatitis C virus (HCV). HCV prevalence is influenced by a complex interplay of drug-use behaviors, social networks, and geography, as well as the availability of interventions, such as needle exchange programs. To adequately address this complexity in HCV epidemic forecasting, we have developed a computational model, the Agent-based Pathogen Kinetics model (APK). APK simulates the PWID population in metropolitan Chicago, including the social interactions that result in HCV infection. We used multiple empirical data sources on Chicago PWID to build a spatial distribution of an in silico PWID population and modeled networks among the PWID by considering the geography of the city and its suburbs. APK was validated against 2012 empirical data (the latest available) and shown to agree with network and epidemiological surveys to within 1%. For the period 2010-2020, APK forecasts a decline in HCV prevalence of 0.8% per year from 44(± 2)% to 36(± 5)%, although some sub-populations would continue to have relatively high prevalence, including Non-Hispanic Blacks, 48(± 5)%. The rate of decline will be lowest in Non-Hispanic Whites and we find, in a reversal of historical trends, that incidence among non-Hispanic Whites would exceed incidence among Non-Hispanic Blacks (0.66 per 100 per years vs 0.17 per 100 person years). APK also forecasts an increase in PWID mean age from 35(± 1) to 40(± 2) with a corresponding increase from 59(± 2)% to 80(± 6)% in the proportion of the population >30 years old. Our studies highlight the importance of analyzing subpopulations in disease predictions, the utility of computer simulation for analyzing demographic and health trends among PWID and serve as a tool for guiding intervention and prevention strategies in Chicago, and other major cities.

    Background This cross-sectional study evaluated the association between unhealthy lifestyle behaviors and the prevalence of chronic kidney disease (CKD) in middle-aged and older men. Methods The subjects included 445 men without a history of cardiovascular disease, stroke, or dialysis treatment, who were not taking medications. Unhealthy lifestyle behaviors were evaluated using a standardized self-administered questionnaire and were defined as follows: 1) lack of habitual moderate exercise, 2) lack of daily physical activity, 3) slow walking speed, 4) fast eating speed, 5) late-night dinner, 6) bedtime snacking, and 7) skipping breakfast. The participants were divided into four categories, which were classified into quartile distributions based on the number of unhealthy lifestyle behaviors (0–1, 2, 3, and ≥4 unhealthy behaviors). Results According to a multivariate analysis, the odds ratio (OR) for CKD (defined as estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m2 and/or proteinuria) was found to be significantly higher in the ≥4 group than in the 0–1 group (OR 4.67; 95% confidence interval [CI], 1.51–14.40). Moreover, subjects’ lack of habitual moderate exercise (OR 3.06; 95% CI, 1.13–8.32) and presence of late-night dinner (OR 2.84; 95% CI, 1.40–5.75) and bedtime snacking behaviors (OR 2.87; 95% CI, 1.27–6.45) were found to be significantly associated with the prevalence of CKD. Conclusions These results suggest that an accumulation of unhealthy lifestyle behaviors, especially those related to lack of habitual moderate exercise and presence of late-night dinner and bedtime snacking may be associated with the prevalence of CKD.

    A cross-sectional study of 250 cases of type 2 diabetes management was conducted in a governmental tertiary care hospital of urban south India to determine the comparative prevalence of type 2 diabetes and its comorbidity with cardiovascular diseases in diabetic population, core drug use indicators and drug utilization pattern in the management of diabetics entirely and with cardiovascular diseases. Highest prevalent age group for type 2 diabetes/cardiovascular diseases (greater incidence in female than male) was 51-60 years. The 62.8% prevalence of cardiovascular diseases in the diabetic population ascertained in the study could provide an evidence-based rationale for the World Health Organization guidelines for the management of hypertension in type 2 diabetics. Incidence of polypharmacy (6.06, the mean number of total drug products prescribed); 59.26% of encounters prescribed antibiotics; 17.6 and 18.5 min of average consultation and dispensing time, respectively; 100% of drugs actually dispensed and adequately labeled; 81.26% of patients having knowledge of correct dosage and average drug cost of Indian Rupees 145.54 per prescription were the core drug use indicators found mainly. Moreover, drugs prescribed from the Essential Drug List were more than 90% and thereby indicated the drug use in this set-up quite rational. Around 71.09% of cardiovascular agents prescribed by generic name revealed the cost effective medical care. Among the agents in type 2 diabetes management, Actrapid(®) (35.43%) was the highest. Among the cardiovascular agents prescribed, lasix (19.37%) was the highest. Cardiovascular agents prescribed orally by 76.48% signified the good prescription habit indicating the improved patients' adherence to the treatment. The present study emphasizes the need of early detection of hypertension as a preliminary diagnostic parameter of cardiovascular diseases in diabetics and appropriate management through concomitant therapy of cardiovascular drugs to

  17. Aging

    PubMed Central

    Park, Dong Choon

    2013-01-01

    Aging is initiated based on genetic and environmental factors that operate from the time of birth of organisms. Aging induces physiological phenomena such as reduction of cell counts, deterioration of tissue proteins, tissue atrophy, a decrease of the metabolic rate, reduction of body fluids, and calcium metabolism abnormalities, with final progression onto pathological aging. Despite the efforts from many researchers, the progression and the mechanisms of aging are not clearly understood yet. Therefore, the authors would like to introduce several theories which have gained attentions among the published theories up to date; genetic program theory, wear-and-tear theory, telomere theory, endocrine theory, DNA damage hypothesis, error catastrophe theory, the rate of living theory, mitochondrial theory, and free radical theory. Although there have been many studies that have tried to prevent aging and prolong life, here we introduce a couple of theories which have been proven more or less; food, exercise, and diet restriction.

    To determine the overall prevalence of skin diseases a whole-body skin examination was performed for 1,932 members (46-years of age) of the Northern Finland Birth Cohort (NFBC 1966), which is a comprehensive longitudinal research program (N = 12,058). A high prevalence of all skin diseases needing treatment was found (N = 1,158). Half of the cases of skin findings were evaluated to be serious enough to require diagnostic evaluation, treatment or follow-up either in a general health care, occupational health care or a secondary care setting. The remaining half were thought to be slight and self-treatment was advised. Males (70%) had more skin diseases needing treatment than females (52%) (P<0.001). The most common skin finding was a benign skin tumor, which was found in every cohort member. Skin infections (44%), eczemas (27%) and sebaceous gland diseases (27%) were the most common skin diseases in the cohort. Moreover, skin infections and eczemas were more commonly seen in the group with low education compared to those with high education (P<0.005). The results strengthen the postulate that skin diseases are common in an adult population. PMID:24911008

    Although pigs are commonly infected with Cryptosporidium spp. and Giardia duodenalis, including potentially zoonotic species or genotypes, little is known about age-related infection levels, seasonal differences and genetic variation in naturally infected pigs raised in organic management systems. Therefore, the current study was conducted to assess seasonal and age-related variations in prevalence and infection intensity of Cryptosporidium and Giardia, evaluate zoonotic potential and uncover correlations between species/genotypes, infection intensity and faecal consistency. Shedding of oocysts and cysts ((oo-)cysts) was monitored at quarterly intervals (September 2011-June 2012) in piglets (n = 152), starter pigs (n = 234), fatteners (n = 230) and sows (n = 240) from three organic farms in Denmark. (oo-)Cysts were quantified by immunofluorescence microscopy; and 56/75 subsamples from Cryptosporidium infected pigs were successfully analysed by PCR amplification and partial sequencing of the small subunit (SSU) 18S rRNA and hsp70genes, while 13/67 Giardia subsamples were successfully analysed by amplification and partial sequencing of the 18S rRNA and the gdh genes. Altogether, Cryptosporidium or Giardia infections were observed in 40.9% (350/856) and 14.0% (120/856) of the pigs, respectively, including 8.2% (70/856) infected with both parasites. Prevalence, intensity of infections and presence of Cryptosporidium species varied significantly between age-groups; 53.3% piglets, 72.2% starter pigs, 40.4% fatteners and 2.9% sows were infected with Cryptosporidium, whereas 2.0% piglets, 27.4% starter pigs, 17.8% fatteners and 5.0% sows were infected with Giardia. The overall prevalence was stable throughout the year, except for dual-infections that were more prevalent in September and December (p < 0.05). The infection intensity was age-related for both parasites, and dual-infected pigs tended to excrete lower levels of oocysts compared to pigs harbouring only

    The objectives of this study were to examine the use of the analgesics for the relief of exercise-associated pain (EAP) and to examine personal and/or exercise characteristics that might potentially predict such use in recreationally trained college-aged individuals. Recreationally trained college-aged students (N = 263) were invited to complete a self-administered 16-item questionnaire concerning personal exercise habits and analgesic use for EAP. The primary dependent variable was analgesic use for EAP, and additional items sought to characterize patterns and behaviors related to the use. Descriptive statistics and frequencies were calculated for all items, and logistic regression was used to evaluate the ability of 4 variables to predict analgesic use for EAP: gender, length of time performing regular exercise, weekly frequency of aerobic exercise, and weekly frequency of resistance exercise. Approximately 36% of respondents reported analgesic use for EAP, with data indicating acute use for what is generally acute pain. With predictors considered individually, gender was a significant predictor, with female respondents being more likely to use analgesics for EAP (p = 0.04). With all predictors considered concurrently, the model did not significantly contribute to the prediction of use in this sample. Potential for misuse was highlighted by a large percentage of users who described themselves as very unlikely to follow label directions and more likely to take a dose exceeding recommendations. In light of research that reports a potential detriment to muscular regeneration when analgesics are consumed with exercise, it is important to be cognizant of the use of these drugs in individuals striving to improve muscular fitness. Coaches and trainers should educate athletes about the associated risks and caution those who may unnecessarily take analgesics.

    Pneumococcal disease is frequent at the extremes of age. While several studies have looked at colonization among young children, much less is known among the elderly. We aimed to evaluate pneumococcal carriage among elderly adults living in Portugal. Between April 2010 and December 2012, nasopharyngeal and oropharyngeal swabs of adults over 60 years of age, living in an urban area (n = 1,945) or in a rural area (n = 1,416), were obtained. Pneumococci were isolated by culture-based standard procedures, identified by optochin susceptibility, bile solubility and PCR screening for lytA and cpsA, and characterized by antibiotype, serotype, and MLST. Associations between pneumococcal carriage, socio-demographic and clinical characteristics were evaluated by univariate analysis and multiple logistic regression. The global prevalence of carriage was 2.3% (95% CI: 1.8–2.8). In the multiple logistic regression analysis, smoking, being at a retirement home, and living in a rural area increased the odds of being a pneumococcal carrier by 4.4-fold (95% CI: 1.9–9.2), 2.0-fold (95% CI: 1.1–3.6) and 2.0-fold (95% CI: 1.2–3.5), respectively. Among the 77 pneumococcal isolates, 26 serotypes and 40 STs were identified. The most prevalent serotypes were (in decreasing order) 19A, 6C, 22F, 23A, 35F, 11A, and 23B, which accounted, in total, for 60.0% of the isolates. Most isolates (93.5%) had STs previously described in the MLST database. Resistance to macrolides, non-susceptibility to penicillin and multidrug resistance were found in 19.5%, 11.7%, and 15.6% of the isolates, respectively. We conclude that the prevalence of pneumococcal carriage in the elderly, in Portugal, as determined by culture-based methods, is low. Serotype and genotype diversity is high. Living in a rural area, in a retirement home, and being a smoker increased the risk of pneumococcal carriage. This study contributes to the establishment of a baseline that may be used to monitor how novel

    We assessed the impact of land use, demographic factors, and season on the prevalence and intensity of Baylisascaris procyonis infections in raccoons (Procyon lotor) in Ontario, Canada. From March to October 2012, we recorded the number of B. procyonis in the intestinal tracts of raccoons submitted to the Canadian Cooperative Wildlife Health Centre for necropsy. Logistic regression models were used to examine associations between the presence of B. procyonis and age (adult, juvenile), sex, land use (suburban/urban, rural), and season (March-June and July-October); negative binomial regression models were used to examine associations between the number of worms and the same variables. We detected B. procyonis in 38% (95% confidence interval 30-47%) of raccoons examined (n=128). In univariable models, the presence of B. procyonis was significantly associated with age, land use, and season (P<0.05). Age was not retained in the multivariable model, and the impact of sex on the presence of B. procyonis varied with land use and season. For example, from March to June, suburban/urban male raccoons were significantly more likely to be infected with B. procyonis than suburban/urban female raccoons. However, later in the summer (July-October), the opposite was true. The median number of worms in the intestinal tracts of infected raccoons was 3 (range 1-116). Worm number was significantly associated with age and season in univariable models; in the multivariable model, juvenile raccoons had significantly more worms than adults, and the impact of season on the number of worms varied with land use and sex. A better understanding of the epidemiology of B. procyonis in raccoons is important for developing appropriate strategies to reduce the risk of human exposure to B. procyonis from the environment.

    Iran has the highest prevalence of multiple sclerosis (MS) in the Middle East and Asia. Rate of emigration has been significantly raised among Iranians and though, multiple studies have been published on prevalence of MS among Iranian emigrants. Here we systematically reviewed these publications. We performed a comprehensive literature search was performed on April 30, 2015 in data bases of MEDLINE, EMBASE, Scopus and Google Scholar for the terms 'multiple sclerosis', 'incidence', 'prevalence', 'epidemiology', 'migration', 'emigrant', 'immigrant', 'Iran', 'Parsis' and 'Persian'. Study location, prevalence day or period, and age of at disease onset were recorded for all the included publications. Nine publications from Sweden, Canada, Norway, UK, and India were included. Only three reported age-adjusted prevalence and six reported age of disease onset. MS prevalence among Iranian emigrants varied from 21 per 100,000 people in Bombay, India in 1985 to 433 per 100,000 people in British Columbia, Canada in 2012. Five studies reported the prevalence in the region of interest, ranging from 1.33 in Bombay, India to 240 in British Columbia, Canada. Five studies also reported the prevalence of MS in the population of the destination country, and in all of them, the prevalence of MS was higher in Iranian immigrants compared to native people. Prevalence studies performed in Iran and also on Iranian emigrants indicate roles for both genetic and environmental factors in MS susceptibility. Data might indicate that living in a high-risk area increases the susceptibility to MS.

    Objectives: To estimate the lifetime risk, prevalence, incidence, and mortality of the principal clinical syndromes associated with frontotemporal lobar degeneration (FTLD) using revised diagnostic criteria and including intermediate clinical phenotypes. Methods: Multisource referral over 2 years to identify all diagnosed or suspected cases of frontotemporal dementia (FTD), progressive supranuclear palsy (PSP), or corticobasal syndrome (CBS) in 2 UK counties (population 1.69 million). Diagnostic confirmation used current consensus diagnostic criteria after interview and reexamination. Results were adjusted to the 2013 European standard population. Results: The prevalence of FTD, PSP, and CBS was 10.8/100,000. The incidence and mortality were very similar, at 1.61/100,000 and 1.56/100,000 person-years, respectively. The estimated lifetime risk is 1 in 742. Survival following diagnosis varied widely: from PSP 2.9 years to semantic variant FTD 9.1 years. Age-adjusted prevalence peaked between 65 and 69 years at 42.6/100,000: the age-adjusted prevalence for persons older than 65 years is double the prevalence for those between 40 and 64 years. Fifteen percent of those screened had a relevant genetic mutation. Conclusions: Key features of this study include the revised diagnostic criteria with improved specificity and sensitivity, an unrestricted age range, and simultaneous assessment of multiple FTLD syndromes. The prevalence of FTD, PSP, and CBS increases beyond 65 years, with frequent genetic causes. The time from onset to diagnosis and from diagnosis to death varies widely among syndromes, emphasizing the challenge and importance of accurate and timely diagnosis. A high index of suspicion for FTLD syndromes is required by clinicians, even for older patients. PMID:27037234

    Background Although gait disorders are common in the elderly, the prevalence and overall burden of these disorders in the general community is not well defined. Methods In a cross-sectional investigation of the population-based Bruneck Study cohort, 488 community-residing elderly aged 60–97 years underwent a thorough neurological assessment including a standardized gait evaluation. Gait disorders were classified according to an accepted scheme and their associations to falls, neuropsychological measures, and quality of life were explored. Results Overall, 32.2% (95% confidence interval [CI] 28.2%–36.4%) of participants presented with impaired gait. Prevalence increased with age (p<0.001), but 38.3% (95%CI 30.1%–47.3%) of the subjects aged 80 years or older still had a normally preserved gait. A total of 24.0% (95%CI 20.4%–28.0%) manifested neurological gait disorders, 17.4% (14.3%–21.0%) non-neurological gait problems, and 9.2% (6.9%–12.1%) a combination of both. While there was no association of neurological gait disorders with gender, non-neurological gait disorders were more frequent in women (p = 0.012). Within the group of neurological gait disorders 69.2% (95%CI 60.3%–76.9%) had a single distinct entity and 30.8% (23.1%–39.7%) had multiple neurological causes for gait impairment. Gait disorders had a significant negative impact on quantitative gait measures, but only neurological gait disorders were associated with recurrent falls (odds ratio 3.3; 95%CI 1.4–7.5; p = 0.005 for single and 7.1; 2.7–18.7; p<0.001 for multiple neurological gait disorders). Finally, we detected a significant association of gait disorders, in particular neurological gait disorders, with depressed mood, cognitive dysfunction, and compromised quality of life. Conclusions Gait disorders are common in the general elderly population and are associated with reduced mobility. Neurological gait disorders in particular are associated with recurrent falls, lower

    Since the Syrian civil war began in 2011, most of the Syrian refugees have immigrated to Turkey due to its open gate policy and the width of the border. By the end of 2015, it was estimated that there were 2.5 million Syrian refugees in Turkey. Many of the Syrian refugees live in Sanliurfa due to its location on the border with Syria. Trichomonas vaginalis, apart from viral agents is the most common parasite among sexually transmitted infection agents. The aim of this study was to determine the prevalence of T.vaginalis among female married Syrian refugees living outside of the camps in Sanliurfa city center, aged between 15-49 years with complaints of vaginitis. This multi-purpose survey was carried out between February and March of 2015, in collaboration with the United Nations Population Fund and Harran University. This study was approved under the heading of "General Health Status of Female Syrian Refugees" by the Ethics Committee of Harran University Faculty of Medicine. A total of 460 Syrian refugees house were selected using the probability cluster sampling method, with a 95% confidence level and a 5% confidence interval with a design effect. Two women refused to participate in the study, and the response rate was 99.6%. Two Syrian nurses, one laboratory technician, and one interpreter who knew Kurdish and Arabic were hired for the field survey. A structured questionnaire written in Turkish was translated to Arabic and used to collect the sociodemographic data during face to face interviews. According to the questionnaire data, the women with the complaints of vaginal discharge, unusual vaginal bleeding and/or dyspareunia were invited to the Gynecology Department of Harran University Research and Training Hospital for a medical examination. During gynecological examination, swab samples obtained from posterior fornix were evaluated by direct microscopy and Giemsa staining methods for the presence of T.vaginalis trophozoites.

    Ballet exposes the hip joint to repetitive loading in extreme ranges of movement and may predispose a dancer to pain and osteoarthritis (OA). The aims of this study were to compare the prevalence of cartilage defects in professional ballet dancers and athletes and to determine the relationship of clinical signs and symptoms. Forty-nine male and female, current and retired professional ballet dancers and 49 age- and sex-matched non-dancing athletes completed hip pain questionnaires, including the Copenhagen Hip and Groin Outcome Score (HAGOS), and underwent hip range of movement (ROM) testing and 3-Tesla magnetic resonance imaging to score cartilage defects (no defect, grade 1: focal partial defect and grade 2: diffuse or full thickness defect). Thirty (61 %) dancers and 27 (55 %) athletes had cartilage defects (p = 0.54). The frequency of grade 1 and 2 cartilage defects did not differ between dancers and athletes (p = 0.83). The frequency of cartilage defects was similar in male and female dancers (p = 0.34), and male and female athletes (p = 0.24). Cartilage defects were not related to history of hip pain (p = 0.34), HAGOS pain (p = 0.14), sports/rec (p = 0.15) scores or hip internal rotation ≤20° (p > 0.01). Cartilage defects were related to age in male dancers (p = 0.002). Ballet dancers do not appear to be at a greater risk of cartilage injury compared to non-dancing athletes. Male dancers develop cartilage defects at an earlier age than athletes and female dancers. Cartilage defects were not related to clinical signs and symptoms; thus, prospective studies are required to determine which cartilage defects progress to symptomatic hip OA.

    Introduction Tobacco use is one of the leading and preventable causes of global morbidities and premature mortalities. The study explores gender differences in the prevalence and determinants of tobacco use among school-aged adolescents (11-17years) in Sudan and South Sudan. Methods The study utilized the national Global Youth Tobacco Survey (GYTS) data collected in 2005 for Sudan (4,277 unweighted; 131,631 weighted). Univariate and bivariate analyses were conducted to examine the associations between the dependent (tobacco use status) and independent variables. Logistic regression analyses were performed to identify the key factors which influence tobacco consumption among adolescents in the 2 Sudans for ever cigarette users, current cigarette users, and users of noncigarette tobacco products. Results There were significant gender differences in the prevalence of ever cigarette users (21.8%; male=13.1%, female=6.5%, p<0.05) and current cigarette users (6.9%; male=4.9%, female = 1.3%, p<0.05) but not among users of noncigarette tobacco products (14.7%; male=6.8%, female=6.1%). Adolescent tobacco use was significantly associated with availability of monthly income or allowance, exposure to tobacco industry promotions, and tobacco-use behavior of familial relations. Knowledge about the harmful effects of secondhand smoke was related with decreased likelihood of tobacco use. Conclusion School programs that focus on health messages alone may not work for the adolescent population. Legislations that ban all types of tobacco advertisements, promotions, and sponsorships among adolescents are needed in the 2 countries. PMID:25404978

    Purpose Breast cancer is one of the primary indications for cryopreservation and subsequent autotransplantation of ovarian tissue. The safety of this fertility preservation method remains questionable, as the presence of disseminated breast tumor cells cannot yet be excluded in the ovarian autografts. We explored the prevalence of ovarian metastases among young breast cancer patients and determined risk factors for the development of ovarian metastases. Methods Using the nationwide database of the Dutch Pathology Registry (PALGA), we identified a cohort of 2648 women with primary invasive breast cancer at age < 41 years in the period 2000–2010 in the Netherlands who subsequently underwent an oophorectomy. From this source population, all cases who had histologically confirmed ovarian metastases were included. For each case of whom clinical data were available, one control without ovarian metastases who matched the time interval between breast cancer diagnosis and oophorectomy was selected. Data were collected on patient characteristics, diagnosis, treatment and follow-up. Results Ovarian metastases were found in 63 out of 2648 patients who met the inclusion criteria. The risk of developing ovarian metastases increased with time passed since breast cancer diagnosis. Multivariate logistic regression analyses showed significant association between tumor stage and the development of ovarian metastases (p = 0.024). Conclusions The prevalence of ovarian metastases was 2.4% among young breast cancer patients. Early ovary removal may reduce the risk of developing ovarian metastases. In breast cancer patients with tumors > 5 cm and/or inflammatory carcinoma, we recommend a cautious approach to ovarian tissue autotransplantation. PMID:28125710

    2014-01-01

    Background The severity and course of spinal pain is poorly understood in adolescents. The study aimed to determine the prevalence and two-year incidence, as well as the course, frequency, and intensity of pain in the neck, mid back, and low back (spinal pain). Methods This study was a school-based prospective cohort study. All 5th and 6th grade students (11–13 years) at 14 schools in the Region of Southern Denmark were invited to participate (N = 1,348). Data were collected in 2010 and again two years later, using an e-survey completed during school time. Results The lifetime prevalence of spinal pain was 86% and 89% at baseline and follow-up, respectively. A group of 13.6% (95% CI: 11.8, 15.6) at baseline and 19.5% (95% CI: 17.1, 22.0) at follow-up reported that they had pain frequently. The frequency of pain was strongly associated with the intensity of pain, i.e., the majority of the participants reported their pain as relatively infrequent and of low intensity, whereas the participants with frequent pain also experienced pain of higher intensity. The two-year incidence of spinal pain varied between 40% and 60% across the physical locations. Progression of pain from one to more locations and from infrequent to more frequent was common over the two-year period. Conclusions Spinal pain is common at the age of 11–15 years, but some have more pain than others. The pain is likely to progress, i.e., to more locations, higher frequency, and higher pain intensity over a two-year period. PMID:24885549

    OBJECTIVE—To investigate the prevalence of metabolic syndrome in the Spanish working population and determine how the prevalence varies according to occupation and sex. RESEARCH DESIGN AND METHODS—This was a cross-sectional study of 259,014 workers (mean age 36.4 years, range [16–74]; 72.9% male) who underwent a routine medical checkup. The Adult Treatment Panel III (2001) definition for metabolic syndrome was used. RESULTS—The prevalence of metabolic syndrome was 11.6% (95% CI 11.5–11.7) in male subjects and 4.1% (4.0–4.2) in female subjects and increased with age. The prevalence of metabolic syndrome varied in the different categories of occupational activity depending on the sex considered. Among female subjects, the age-adjusted prevalence of metabolic syndrome was higher in blue-collar than in white-collar workers, but this difference was not evident among male workers. CONCLUSIONS—The prevalence of metabolic syndrome varies in the different categories of occupational activity in the Spanish working population. This variation also depends on sex. PMID:18753667

    People who inject drugs (PWID) are at high risk for blood-borne pathogens transmitted during the sharing of contaminated injection equipment, particularly hepatitis C virus (HCV). HCV prevalence is influenced by a complex interplay of drug-use behaviors, social networks, and geography, as well as the availability of interventions, such as needle exchange programs. To adequately address this complexity in HCV epidemic forecasting, we have developed a computational model, the Agent-based Pathogen Kinetics model (APK). APK simulates the PWID population in metropolitan Chicago, including the social interactions that result in HCV infection. We used multiple empirical data sources on Chicago PWID tomore » build a spatial distribution of an in silico PWID population and modeled networks among the PWID by considering the geography of the city and its suburbs. APK was validated against 2012 empirical data (the latest available) and shown to agree with network and epidemiological surveys to within 1%. For the period 2010–2020, APK forecasts a decline in HCV prevalence of 0.8% per year from 44(±2)% to 36(±5)%, although some sub-populations would continue to have relatively high prevalence, including Non-Hispanic Blacks, 48(±5)%. The rate of decline will be lowest in Non-Hispanic Whites and we find, in a reversal of historical trends, that incidence among non-Hispanic Whites would exceed incidence among Non-Hispanic Blacks (0.66 per 100 per years vs 0.17 per 100 person years). APK also forecasts an increase in PWID mean age from 35(±1) to 40(±2) with a corresponding increase from 59(±2)% to 80(±6)% in the proportion of the population >30 years old. Our research highlight the importance of analyzing sub-populations in disease predictions, the utility of computer simulation for analyzing demographic and health trends among PWID and serve as a tool for guiding intervention and prevention strategies in Chicago, and other major cities.« less

    A high prevalence of hepatitis B (HBV) and C virus (HCV) infections has been reported among specific patient groups in Libya; a survey was thus designed to determine the extent of the problem at the national level. A multi-stage sampling design covering all administrative areas of Libya was applied, covering > 65,000 individuals of all age groups. All subjects gave a blood sample and completed a questionnaire on demographic and risk behaviour data. The prevalence of HBV surface antigen (HBsAg) and anti-HCV were 2.2% and 1.3% respectively. The prevalence of anti-HCV increased with age, rising gradually after age 30 years, in contrast to a stable prevalence of HBsAg in all age groups 10+ years. Age-adjusted risk factors for HCV infection were previous hospitalization, surgical operations, previous blood transfusions and intravenous drug use; for HBV infection only family exposure or contact with HBV case were identified.

    The School Health Examination Survey is a nationwide examination carried out annually in Japan, and the results are entered into a prefectural-level physical measurement database. We used this database to determine the geographical differences in a population-based cross-sectional growth curve and investigated the association between age at peak height velocity (PHV) and the prevalence rate of overweight in children among Japanese prefectures. Mean prefectural-level age at PHV was estimated by the cubic spline-fitting procedure using cross-sectional whole-year prefectural mean height data (5-17 years, 2006-2013), and 8-year (2006-2013) means of the standardized prevalence rates of overweight children and other anatomical data (8-year standardized weight and height) were recalculated. Mean prefectural age at PHV was more strongly correlated with the mean prefectural prevalence rate of overweight (age 5-8 years) than with other weights or heights in both sexes. On the basis of these findings and their confirmation by multiple regression analysis, the prevalence rate of overweight was selected as a primary factor to explain the geographical difference in age at PHV. These findings suggest that childhood overweight is a dominant factor responsible for the observed geographical differences in onset of puberty in Japan.

    Mature non-senescent leaves of evergreen species become gradually shaded as new foliage develops and canopy expands, but the interactive effects of integrated light during leaf formation (Q(int)G), current light (Q(int)C) and leaf age on foliage photosynthetic competence are poorly understood. In Quercus ilex L., we measured the responses of leaf structural and physiological variables to Q(int)C and Q(int)G for four leaf age classes. Leaf aging resulted in increases in leaf dry mass per unit area (M(A)), and leaf dry to fresh mass ratio (D(F)) and decreases in N content per dry mass (N(M)). N content per area (N(A)) was independent of age, indicating that decreases in N(M) reflected dilution of leaf N because of accumulation of dry mass (NA = N(M) M(A)). M(A), D(F) and N(A) scaled positively with irradiance, whereas these age-specific correlations were stronger with leaf growth light than with current leaf light. Area-based maximum ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) carboxylase activity (V(cmax)A), capacity for photosynthetic electron transport (J(max)A) and the rate of non-photorespiratory respiration in light (R(d)A) were also positively associated with irradiance. Differently from leaf structural characteristics, for all data pooled, these relationships were stronger with current light with little differences among leaves of different age. Acclimation to current leaf light environment was achieved by light-dependent partitioning of N in rate-limiting proteins. Mass-based physiological activities decreased with increasing leaf age, reflecting dilution of leaf N and a larger fraction of non-photosynthetic N in older leaves. This resulted in age-dependent modification of leaf photosynthetic potentials versus N relationships. Internal diffusion conductance (g(m)) per unit area (g(m)A) increased curvilinearly with increasing irradiance for two youngest leaf age classes and was independent of light for older leaves. In contrast, g(m) per dry

    Background: The objectives of this study were to quantitatively assess the geographic heterogeneity of cancer prevalence in selected Western Countries and to explore the associations between its determinants. Methods: For 20 cancer sites, 5-year cancer prevalence, incidence, and survival were observed and age standardised for the mid 2000s in the United States, Nordic European Countries, Italy, Australia, and France. Results: In Italy, 5-year crude prevalence for all cancers was 1.9% in men and 1.7% in women, while it was ∼1.5% in all other countries and sexes. After adjustment for the different age distribution of the populations, cancer prevalence in the United States was higher (20% in men and 10% in women) than elsewhere. For all cancers combined, the geographic heterogeneities were limited, though relevant for specific cancers (e.g., prostate, showing >30% higher prevalence in the United States, or lung, showing >50% higher prevalence in USA women than in other countries). For all countries, the correlations between differences of prevalence and differences of incidence were >0.9, while prevalence and survival were less consistently correlated. Conclusion: Geographic differences and magnitude of crude cancer prevalence were more strongly associated with incidence rates, influenced by population ageing, than with survival rates. These estimates will be helpful in allocating appropriate resources. PMID:23799856

    Background This study sought to describe stroke prevalence in Spanish elderly populations and compare it against that of other European countries. Methods We identified screening surveys -both published and unpublished- in Spanish populations, which fulfilled specific quality requirements and targeted prevalence of stroke in populations aged 70 years and over. Surveys covering seven geographically different populations with prevalence years in the period 1991–2002 were selected, and the respective authors were then asked to provide descriptions of the methodology and raw age-specific data by completing a questionnaire. In addition, five reported screening surveys in European populations furnished useful data for comparison purposes. Prevalence data were combined, using direct adjustment and logistic regression. Results The overall study population, resident in central and north-eastern Spain, totalled 10,647 persons and yielded 715 cases. Age-adjusted prevalences, using the European standard population, were 7.3% for men, 5.6% for women, and 6.4% for both sexes. Prevalence was significantly lower in women, OR 0.79 95% CI 0.68–0.93, increased with age, particularly among women, and displayed a threefold spatial variation with statistically significant differences. Prevalences were highest, 8.7%, in suburban, and lowest, 3.8%, in rural populations. Compared to pooled Spanish populations, statistically significant differences were seen in eight Italian populations, OR 1.39 95%CI (1.18–1.64), and in Kungsholmen, Sweden, OR 0.40 95%CI (0.27–0.58). Conclusion Prevalence in central and north-eastern Spain is higher in males and in suburban areas, and displays a threefold geographic variation, with women constituting the majority of elderly stroke sufferers. Compared to reported European data, stroke prevalence in Spain can be said to be medium and presents similar age- and sex-specific traits. PMID:17042941

    Background Hypertension and musculoskeletal disorders are highly prevalent in adult populations. The objective of this study was to investigate the association between hypertension and prevalence of low back pain (LBP) and osteoarthritis in Koreans. Methods A total 17,128 participants (age ≥20 years) who answered low back pain and osteoarthritis items in the 4th Korean National Health and Nutrition Examination Survey (2007–2009) were analyzed. Odds ratios were calculated using logistic regression and were adjusted for age, sex, income level, education, occupation, BMI, smoking status, alcohol consumption, and physical activity. Results Lifetime prevalence of LBP in hypertensive subjects was 34.4%, and that of osteoarthritis 26.2%. LBP prevalence was significantly lower in hypertensives (fully adjusted OR 0.79; 95% CI 0.70–0.90), and both LBP and osteoarthritis prevalence was significantly lower in participants with systolic blood pressure ≥140mmHg than those with <120mmHg (fully adjusted OR 0.81; 95% CI 0.70–0.94, and 0.81; 95% CI 0.68–0.96, respectively). Prevalence of LBP in subjects with diastolic blood pressure ≥90mmHg was also significantly lower than those with <80mmHg (fully adjusted OR 0.73; 95% CI 0.63–0.85). LBP and osteoarthritis prevalence did not differ by systolic or diastolic blood pressure interval in respondents taking antihypertensive medication. LBP and osteoarthritis prevalence increased with longer hypertension duration (fully adjusted p for trend 0.028, and 0.0008, respectively). Conclusions Hypertension showed an inverse relationship with LBP and osteoarthritis prevalence, which may be ascribed to hypertension-associated hypalgesia, and antihypertensive medication intake and longer hypertension duration attenuated this association.

    Background Age, period and cohort (APC) analyses, using representative, population-based descriptive data, provide additional understanding behind increased prevalence rates. Methods Data on obesity and diabetes from the South Australian (SA) monthly chronic disease and risk factor surveillance system from July 2002 to December 2013 (n = 59,025) were used. Age was the self-reported age of the respondent at the time of the interview. Period was the year of the interview and cohort was age subtracted from the survey year. Cohort years were 1905 to 1995. All variables were treated as continuous. The age-sex standardised prevalence for obesity and diabetes was calculated using the Australia 2011 census. The APC models were constructed with ‘‘apcfit’’ in Stata. Results The age-sex standardised prevalence of obesity and diabetes increased in 2002-2013 from 18.6% to 24.1% and from 6.2% to 7.9%. The peak age for obesity was approximately 70 years with a steady increasing rate from 20 to 70 years of age. The peak age for diabetes was approximately 80 years. There were strong cohort effects and no period effects for both obesity and diabetes. The magnitude of the cohort effect is much more pronounced for obesity than for diabetes. Conclusion The APC analyses showed a higher than expected peak age for both obesity and diabetes, strong cohort effects with an acceleration of risk after 1960s for obesity and after 1940s for diabetes, and no period effects. By simultaneously considering the effects of age, period and cohort we have provided additional evidence for effective public health interventions. PMID:25923664

    PubMed Central

    2014-01-01

    Background The aim of this study was to estimate the prevalence of tooth wear in the aging population of northwest China and to investigate the factors associated with such tooth wear. Methods Cross-sectional analytic clinical and questionnaire study was performed in 704 participants who had a mean age of 46.5 ± 0.2 SD and of which 367(52.13%) were males and 337(47.87%) female. These participants were invited when they attended the hospital which located in northwest China for routine oral examination. Results In the maxilla of the examined patients, the rate of tooth wear varied from 85.51% for molar group, 89.77% for premolar group, 100.0% for canine group to 87.22% for incisor group. In the mandible, the rates were 86.36%, 88.92%, 100.0% and 91.19% for the four groups respectively. Moreover, both the incisor and canine groups of these patients showed median scores of 3, the premolar group showed a median score of 1, and the molar group had a median score of 2. Additionally, multiple factors were considered to contribute to these patterns of tooth wear, especially the habitual consumption of a hard or sour diet (P < 0.05,odds ratio 1.21, 95% confidence intervals 1.04-1.49). Conclusions Tooth wear is a common disease in which the anterior teeth exhibit greater wear than posterior teeth. The data support an association between tooth wear and dietary patterns.

    This study reports the epidemiology of respiratory syncytial virus (RSV) in hospitalized children in Cyprus over three successive seasons (2010-2013) and the association between prevalent genotypes and disease severity. RSV infections had a circulation pattern from December to March. Most RSV-positive children (83%) were aged <2 years. Genotyping of RSV isolates showed that during the first winter season of the study (2010-2011), the only RSV genotype circulating was GA2 (RSV-A), followed by genotype BA (RSV-B) in the next winter season with only few sporadic cases of GA2. During the last winter season of the study (2012-2013) the newly emerged RSV genotype ON1 (RSV-A) was virtually the only circulating genotype. Children infected with genotype ON1 suffered a significantly milder illness compared to infections with genotypes GA2 and BA with a higher percentage of BA-infected children requiring oxygen. Our findings are in contrast to the majority of published reports that suggest RSV-A causes more severe illness than RSV-B. Therefore, further investigation of the association between RSV genotypes and disease severity is required, as it might affect treatment strategies in the future.

    Objective The aim of this study was to examine the prevalence of major congenital malformations associated with antiepileptic drug (AED) treatment in pregnancy. Patients and methods Using data from The Health Improvement Network, we identified women who have given live birth and their offspring. Four subgroups were selected based on the AED treatment in early pregnancy, valproate, carbamazepine, lamotrigine and women not receiving AED treatment. We compared the prevalence of major congenital malformations within children of these four groups and estimated prevalence ratios (PRs) using Poisson regression adjusted for maternal age, sex of child, quintiles of Townsend deprivation score and indication for treatment. Results In total, 240,071 women were included in the study. A total of 229 women were prescribed valproate in pregnancy, 357 were prescribed lamotrigine and 334 were prescribed carbamazepine and 239,151 women were not prescribed AEDs. Fifteen out of 229 (6.6%) women prescribed valproate gave birth to a child with a major congenital malformation. The figures for lamotrigine, carbamazepine and women not prescribed AEDs were 2.7%, 3.3% and 2.2%, respectively. The prevalence of major congenital malformation was similar for women prescribed lamotrigine or carbamazepine compared to women with no AED treatment in pregnancy. For women prescribed valproate in polytherapy, the prevalence was fourfold higher. After adjustments, the effect of estimates attenuated, but the prevalence remained two- to threefold higher in women prescribed valproate. Conclusion The results of our study suggest that lamotrigine and carbamazepine are safer treatment options than valproate in pregnancy and should be considered as alternative treatment options for women of childbearing potential and in pregnancy.

    The prevalence of goitre in areas with mildly excessive iodine in drinking-water is still under debate. The aim of the present study was to explore the prevalence of goitre and its epidemiological characteristics in these areas using WHO criteria. To this end, three towns with a median water iodine (MWI) of 150-300 μg/l were selected randomly in Hengshui City of Hebei Province of China, and one town with a MWI of 105 μg/l was chosen as a control. A total of 452 children in the three towns and 120 children in the control town were randomly selected to measure thyroid volume (T vol) by ultrasound. The goitre status of these children was judged using the criteria recommended by the WHO. The overall goitre prevalences in the three towns were 24·6 % (111/452) by age-specific T vol and 33·0 % (149/452) by body surface area (BSA)-adjusted T vol, which were significantly higher than that in the control town by both age-specific T vol (14·0 % (17/120), P= 0·015) and BSA-adjusted T vol (17·5 % (21/120), P= 0·001). Significant differences were found neither in goitre prevalences across sex by both age-specific T vol (P= 0·078) and BSA-adjusted T vol (P= 0·692) nor in that across age group by both BSA-adjusted T vol (P= 0·461) and age-specific T vol (P= 0·183). The present study found a high prevalence of goitre in children living in areas with mildly excessive iodine in drinking-water in Hebei Province. No significant differences were found in goitre prevalences across sex and age group. These results suggest that the T vol reference values recommended by the WHO could be too low for Chinese children.

    In 1989 a national survey was carried out on children aged 3 to 4 years attending nursery schools, to investigate the prevalence of caries experience, nursing bottle caries and enamel defects in the primary dentition, and these children's dentally related habits. In the first part of the study, examination of 482 Antiguan children showed that the dmft and dmfs values were 0.80 and 1.26 respectively, and that 77 per cent of the children were caries free; 4.6 per cent of children had nursing bottle caries; and enamel defects occurred in 24 per cent of children. No significant difference was found in oral health between urban and rural samples. In the second part, which was an interview survey, habits such as thumb sucking (13 per cent), not brushing their teeth (3 per cent), and swallowing fluoride toothpaste (13 per cent) were found among 369 children. In the third (a questionnaire) survey, a response rate of 63 per cent was obtained. Significantly more of the children with nursing bottle caries (78.6 per cent) had the habit of sleeping with a feeding bottle than occurred in caries free children (25.6 per cent), but there was no difference in the infant feeding pattern. The children with enamel defects were breast fed for a shorter period and had an earlier introduction to bottle feeding, compared with children without enamel defects. In the final part of the survey, an assessment of snack eating habits at school, a 58 per cent response rate was achieved. The majority of children often brought healthier snacks, together with daily sugar-rich drinks. Significantly more caries free children brought sugary snacks less frequently than children with caries experience.

    Older adults display alterations in neural reflections of conflict-related processing. We examined response times (RTs), error rates, and event-related potential (ERP; N2 and P3 components) indices of conflict adaptation (i.e., congruency sequence effects) a cognitive control process wherein previous-trial congruency influences current-trial performance, along with post-error slowing, correct-related negativity (CRN), error-related negativity (ERN) and error positivity (Pe) amplitudes in 65 healthy older adults and 94 healthy younger adults. Older adults showed generalized slowing, had decreased post-error slowing, and committed more errors than younger adults. Both older and younger adults showed conflict adaptation effects; magnitude of conflict adaptation did not differ by age. N2 amplitudes were similar between groups; younger, but not older, adults showed conflict adaptation effects for P3 component amplitudes. CRN and Pe, but not ERN, amplitudes differed between groups. Data support generalized declines in cognitive control processes in older adults without specific deficits in conflict adaptation.

    Short (≤6 hours) and long (>9 hours) sleep durations are risk factors for mortality and morbidity. To investigate whether the prevalences of short and long sleep durations have increased from the 1970s to the 2000s, we analyzed data from repeated cross-sectional surveys of 10 industrialized countries (38 nationally representative time-use surveys; n = 328,018 adults). Logistic regression models for each country were used to determine changes in the prevalence of short and long sleep durations over time, controlling for sampling differences in gender, age, number of weekend days included, and season of data collection. Over the periods covered by data, the prevalence of short sleep duration increased in Italy (adjusted odds ratio = 2.64, 95% confidence interval (CI): 2.41, 2.89) and Norway (adjusted odds ratio = 2.33, 95% CI: 1.77, 3.08) but decreased in Sweden, the United Kingdom, and the United States. The prevalence of long sleep duration increased in Australia (adjusted odds ratio = 1.14, 95% CI: 1.05, 1.25), Finland (adjusted odds ratio = 1.30, 95% CI: 1.14, 1.48), Sweden (adjusted odds ratio = 1.51, 95% CI: 1.35, 1.69), the United Kingdom (adjusted odds ratio = 2.03, 95% CI: 1.68, 2.46), and the United States (adjusted odds ratio = 1.50, 95% CI: 1.36, 1.65) but decreased in Canada and Italy. No changes were observed in Germany or the Netherlands. Limited increases in short sleep duration challenge the claim of increasingly sleep-deprived societies. Long sleep duration is more widespread than is short sleep duration. It has become more prevalent and thus should not be overlooked as a potential contributor to ill health.

    Aims This study aimed to evaluate the incidence and prevalence of blindness, sight impairment, and other visual acuity (VA) states in patients receiving ranibizumab for neovascular age-related macular degeneration (nAMD) in Gloucestershire. Methods Serial VA and injection data for all treatment-naive patients receiving their first intravitreal injections of ranibizumab for nAMD in the Gloucestershire National Health Service Ophthalmology department between 2008 and 2010 were extracted from an electronic medical record system. Results The prevalence of blindness (VA in the better-seeing eye ≤25 Early Treatment Diabetic Retinopathy Study (ETDRS) letters) at the time of first intravitreal injection was 0.8%, increasing to 3.5% after 3 years. The prevalence of sight impairment (VA in the better-seeing eye 26–39 ETDRS letters) increased from 4.1% at baseline to 5.5% after 3 years. The incidence of initiating ranibizumab treatment for nAMD in people aged ≥50 years in Gloucestershire was 111 people per 100 000 population in 2009, and 97 people in 2010. The incidence of patients meeting the visual criteria for blindness and sight impairment registration from treated nAMD in people aged ≥50 years in Gloucestershire was 3.5 and 9.7 people, respectively per 100 000 population in 2010. Conclusion This is the first real-world study on the incidence and prevalence of eligibility for blindness and sight impairment registration in treated nAMD in the UK based on VA data. The incidence and prevalence of eligibility for certification of blindness or sight impairment in patients treated with ranibizumab for nAMD is low in Gloucestershire, with only 3.6% of the incident population progressing to blindness in 2010.

    Background Physical inactivity is a leading cause of morbidity, disability and premature mortality in the U.S. and worldwide. This study aimed to map the prevalence of physical inactivity across U.S. states over the past three decades, and estimate the over-time adjusted changes in the prevalence of physical inactivity in each state. Methods Individual-level data (N = 6,701,954) were taken from the 1984–2015 Behavioral Risk Factor Surveillance System (BRFSS), an annually repeated cross-sectional survey of state-representative adult population. Prevalence of self-reported leisure-time physical inactivity was estimated by state and survey year, accounting for the BRFSS sampling design. Logistic regressions were performed to estimate the changes in the prevalence of physical inactivity over the study period for each state, adjusting for individual characteristics including sex, age, race/ethnicity, education, marital status, and employment status. Results The prevalence of leisure-time physical inactivity varied substantially across states and survey years. In general, the adjusted prevalence of physical inactivity gradually declined over the past three decades in a majority of states. However, a substantial proportion of American adults remain physically inactive. Among the 50 states and District of Columbia, 45 had over a fifth of their adult population without any leisure-time physical activity, and 8 had over 30% without physical activity in 2015. Moreover, the adjusted prevalence of physical inactivity in several states (Arizona, North Carolina, North Dakota, Utah, West Virginia, and Wyoming) remained largely unchanged or even increased (Minnesota and Ohio) over the study period. Conclusions Although the prevalence of physical inactivity declined over the past three decades in a majority of states, the rates remain substantially high and vary considerably across states.

    Most HPV prevalence studies have been carried out in high-resource countries with few studies focused on low-resource regions where highest HPV prevalence in the world occurs. This study reports on prevalence of IgG antibodies against HPVs among women of childbearing age in Port Harcourt, Nigeria. One hundred and eighty-two consented women (age-range 19-45 years) were consecutively recruited. Demographic/behavioral data and 5 mL blood samples were collected from each woman. Plasma of each sample was assayed for HPV-6/11/16/18 virus-like particles using a HPV IgG ELISA kit. The overall anti-HPV prevalence was 4.9% while 7.7% with itching/wound in the private part tested positive. Most (88.9%) of the seropositive women were sexually active. Group-specific seropositivity was low (0.0-10.0%). It also showed that all the 9(100.0%) who tested positive to the HPV responded "yes" to no information on the source of HPV information. Being younger, married, high educational level, religion, and lack of information on HPV were the main correlates of HPV positivity among these women. None was vaccinated and would have been naturally exposed to at least one of HPV-6/11/16/18. With 4.9% seropositivity and lack of information regarding HPV among these women, this study recommends a statewide enlightenment campaign and vaccination.

    The purpose of this study was to investigate the prevalence of hypothyroidism among hospitalized patients with type 2 diabetes mellitus and its related factors, and to assess the prevalence of macrovascular and microvascular diseases among type 2 diabetes mellitus inpatients with hypothyroidism and euthyroidism. A total of 1662 type 2 diabetes mellitus inpatients hospitalized at the Metabolic Diseases Hospital, Tianjin Medical University from 1 January 2008 to 1 March 2013 were included in this study. Information on demographic and anthropometric factors and additional variables related to hypothyroidism were collected from medical records. Prevalence rates were calculated and standardized using direct method based on the age-specific and sex-specific structure of all participants. Data were analyzed using binary logistic regression with adjustment for potential confounders. The prevalence of hypothyroidism among type 2 diabetes mellitus inpatients was 6.8 %, and 77.0 % of the patients with hypothyroidism had subclinical hypothyroidism. The prevalence of hypothyroidism increased with age, and was higher in women (10.8 %) than in men (3.4 %). Older age (odds ratio, 1.74; 95 % confidence interval, 1. 05 to 2.89), female gender (odds ratio, 2.02; 95 % confidence interval, 1.05 to 3.87), and positive thyroid peroxidase antibody (odds ratio, 4.99; 95 % confidence interval, 2.83 to 8.79) were associated with higher odds of hypothyroidism among type 2 diabetes mellitus inpatients. The type 2 diabetes mellitus inpatients with hypothyroidism had higher prevalence of cerebrovascular diseases than those with euthyroidism after adjustment for age and gender. The prevalence of hypothyroidism among type 2 diabetes mellitus inpatients was 6.8 %, and most patients had subclinical hypothyroidism. Older age, female gender, and positive thyroid peroxidase antibody could be indicators for detecting hypothyroidism in type 2 diabetes mellitus inpatients.

    Background. This study assesses the lifetime and active prevalence of epilepsy in Spain in people older than 18 years. Methods. EPIBERIA is a population-based epidemiological study of epilepsy prevalence using data from three representative Spanish regions (health districts in Zaragoza, Almería, and Seville) between 2012 and 2013. The study consisted of two phases: screening and confirmation. Participants completed a previously validated questionnaire (EPIBERIA questionnaire) over the telephone. Results. A total of 1741 valid questionnaires were obtained, including 261 (14.99%) raising a suspicion of epilepsy. Of these suspected cases, 216 (82.75%) agreed to participate in phase 2. Of the phase 2 participants, 22 met the International League Against Epilepsy's diagnostic criteria for epilepsy. The estimated lifetime prevalence, adjusted by age and sex per 1,000 people, was 14.87 (95% CI: 9.8–21.9). Active prevalence was 5.79 (95% CI: 2.8–10.6). No significant age, sex, or regional differences in prevalence were detected. Conclusions. EPIBERIA provides the most accurate estimate of epilepsy prevalence in the Mediterranean region based on its original methodology and its adherence to ILAE recommendations. We highlight that the lifetime prevalence and inactive epilepsy prevalence figures observed here were compared to other epidemiological studies. PMID:26783554

    Objective To present the prevalence of self-reported diabetes in Indigenous and non-Indigenous participants in the National Eye Health Survey. Research Design and Methods 3098 non-Indigenous Australians aged 50–98 years and 1738 Indigenous Australians aged 40–92 years were examined in 30 randomly selected sites, stratified by remoteness. A history of diabetes was obtained using an interviewer-administered questionnaire. Results 13.91% (431/3098) of non-Indigenous Australians and 37.11% (645/1738) of Indigenous Australians had self-reported diabetes. The age-adjusted prevalence of self-reported diabetes for non-Indigenous and Indigenous Australians was 11.49% and 43.77%, respectively (p <0.001). The prevalence of self-reported diabetes increased markedly with age (OR = 1.04 per year, p = 0.017). Indigenous Australians living in very remote areas were more likely to have self-reported diabetes than those in major city areas (OR = 1.61, p = 0.038). Conclusions The prevalence of self-reported diabetes in Australia was high, with the prevalence being almost 4 times higher in Indigenous Australians compared with non-Indigenous Australians. With the prevalence of diabetes likely to increase, the results of this national survey may inform future policy, planning and funding allocation to assist in controlling the diabetes epidemic.

    An early requirement of the UK's Diabetes National Service Framework is enumeration of the total affected population. Existing estimates tend to be based on incomplete lists. In a study conducted over one year in North Liverpool, we compared crude prevalence rates for type 1 and type 2 diabetes with estimates obtained by capture-recapture (CR) analysis of multiple incomplete patient lists, to assess the extent of unascertained but diagnosed cases. Patient databases were constructed from six sources-a hospital diabetes centre; general practitioner registers; hospital admissions with a diagnosis of diabetes; a hospital diabetic retinal clinic; a research list of patients with diabetes admitted with stroke; and a local children's hospital. Log linear modelling was used to estimate missing cases, hence total prevalence. The crude prevalence of diabetes was 1.5% (95% confidence interval [CI] 1.41, 1.52), compared with a CR-adjusted rate of 3.1% (CI 3.03, 3.19). Age-banded CR-adjusted prevalence was always higher in males than in females and the difference became more pronounced with increasing age. Among males, CR-adjusted prevalence rose from 0.4% at age 10-19 years to 18.3% at 80+ years; in females the corresponding figures were 0.4% and 9.3%. The gap between crude and CR-estimated prevalence points to a rate of 'hidden diabetes' that has substantial implications for future diabetes care.

    Introduction Racial disparities in obesity exist at the individual and community levels. Retail food environment has been hypothesized to be associated with racial disparities in obesity prevalence. This study aimed to quantify how much food environment measures explain racial disparities in obesity at the county level. Methods Data from 2009 to 2010 on 3,135 U.S. counties were extracted from the U.S. Department of Agriculture Food Environment Atlas and the Behavioral Risk Factor Surveillance System and analyzed in 2013. Oaxaca–Blinder decomposition was used to quantify the portion of the gap in adult obesity prevalence observed between counties with a high and low proportion of African American residents is explained by food environment measures (e.g., proximity to grocery stores, per capita fast food restaurants). Counties were considered to have a high African American population if the percentage of African American residents was >13.1%, which represents the 2010 U.S. Census national estimate of percentage African American citizens. Results There were 665 counties (21%) classified as a high African American county. The total gap in mean adult obesity prevalence between high and low African American counties was found to be 3.35 percentage points (32.98% vs 29.63%). Retail food environment measures explained 13.81% of the gap in mean age-adjusted adult obesity prevalence. Conclusions Retail food environment explains a proportion of the gap in adult obesity prevalence observed between counties with a high proportion of African American residents and counties with a low proportion of African American residents.

    Parkinson's disease (PD) is largely unstudied among American Indians. Unique populations might harbor clues to elusive causes. We describe the incidence and prevalence of PD among Navajo people residing in the Navajo Nation, home to the largest American Indian tribe in the United States. We analyzed 2001-2011 inpatient and outpatient visit data for Navajo people obtained from the Indian Health Service, which provides health care to American Indian people living on the Navajo Reservation. Cases were defined by at least two inpatient or outpatient visits with the diagnosis of PD. Crude and age-adjusted incidence and prevalence rates were calculated overall as well as by age, sex, region of residence, and time period. Five hundred twenty-four Navajo people with median age-at-onset of 74.0 years were diagnosed with PD during the study period, yielding an average annual crude incidence rate of 22.5/100,000. Age-specific incidence was 232.0 for patients 65 years of age or older and 302.0 for 80 years of age or older. Age-adjusted incidence was 35.9 overall (238.1 for ≥65 years), was higher in men than in women (47.5 vs. 27.7; P<0.001), varied by region (P=0.03), and was similar between time periods (2002-2004 vs. 2009-2011). The age-adjusted point prevalence rate was 261.0. The rate of PD among Navajo People appears to be as high as or higher than rates reported in many other populations. Rates increased to the highest age group, consistent with population-based studies. Further investigation is warranted to examine risk factors for PD in this remote population.

    This study assesses whether men's ART use mitigates HIV-risk within age-disparate partnerships. Using data from the 2012 South African National HIV survey, we analyzed differences in HIV prevalence and ART use between men in age-disparate and age-similar partnerships with young women aged 15-29 using multiple logistic regression analyses. Within partnerships involving women 15-24 years old, men in age-disparate partnerships were more likely to be HIV-positive (5-9 year age-gap: aOR 2.8, 95%CI 1.4-5.2; p < 0.01; 10+ year age-gap: aOR 2.2, 95%CI 1.0-4.6; p < 0.05). Men in age-disparate partnerships who were 5-9 years older were significantly more likely to be HIV-positive and ART-naïve (aOR 2.4, 95%CI 1.2-4.8; p < 0.05), while this was not the case for men 10+ years older (aOR 1.5, 95%CI 0.7-3.6; p = 0.32). No evidence was found that 25-29 year old women were at greater HIV-risk in age-disparate partnerships. Our results indicate that young women aged 15-24 have a greater likelihood of exposure to HIV through age-disparate partnerships, but ART use among men 10+ years older could mitigate risk.

    Background The majority of Americans consume alcoholic beverages. Alcohol interacts negatively with numerous commonly prescribed medications. Yet, on a population level, little is known about use of alcohol interactive (AI) prescription medications among drinkers. Purpose To determine the prevalence of AI prescription medication use among current drinkers in the US population. Methods Data were from the National Health and Nutrition Examination Survey (NHANES 1999–2010); 26,657 adults aged ≥20 years had data on past year alcohol consumption and past month prescription medication use. Analyses were adjusted for covariates: age, race/ethnicity, education, marital status, and smoking. Statistical procedures accounted for survey stratification, clustering, and non-response. Analyses were weighted to be nationally representative. Results The unadjusted total prevalence of AI medication use was 42.8% (95% CI [CI] 41.5–44.0). Among current drinkers, adjusted prevalence was 41.5% (CI 40.3–42.7). Among participants aged ≥65 total prevalence of AI medication use was 78.6% (CI 77.3–79.9) and adjusted prevalence among current drinkers was 77.8% (CI 75.7–79.7). The AI medications most commonly used by current drinkers were cardiovascular agents, central nervous system (CNS) agents, and metabolic agents. Conclusions Our results suggest that there could be substantial simultaneous exposure to alcohol and AI prescription medications in the US population. Given the adverse health risks of combining alcohol with AI prescription medications, future efforts are needed to collect data to determine actual simultaneous prevalence. PMID:25597432

  12. Adjusting for nonresponse bias in a health examination survey.

    There is a potential for nonresponse bias in most population studies using health examinations. This is true of the Mexican American portion of the Hispanic Health and Nutrition Examination Survey (HHANES), conducted by the National Center for Health Statistics, in which unit nonresponse to the examination accounted for 24 percent of the sample. Even though the full effect of nonresponse can never be really known, ancillary information from the interview sample can be used in an attempt to adjust for bias in estimates. Two techniques for nonresponse bias adjustment are presented and illustrated using health status level and hypertension status from published studies based on the HHANES of 1982-84. The first approach uses conditional probabilities and the second approach uses direct standardization. The examples examine whether or not an adjustment for socioeconomic status, sex, and age--variables related to both response status and the conditions under study--changes the prevalence estimates of (a) Mexican Americans who report poor, fair, or good health status and (b) hypertension among Mexican Americans.

    Studies of antenatal women form the predominant source of data on HIV-1 prevalence in Africa. Identifying factors associated with prevalent HIV is important in targeting diagnostic services and care. Between November 1997 and January 2000, 14,110 postnatal women from Harare, Zimbabwe were tested by ELISAs reactive to both HIV-1 and HIV-2; a subset of positive samples was confirmed with assays specific for HIV-1 and HIV-2. Baseline characteristics were elicited and modelled to identify risk factors for prevalent HIV infection. HIV-1 and HIV-2 prevalences were 32.0% (95% CI 31.2-32.8) and 1.3% (95% CI 1.1-1.5), respectively; 4% of HIV-1-positive and 99% of HIV-2-positive women were co-infected. HIV-1 prevalence increased from 0% among 14-year-olds to >45% among women aged 29-31 years, then fell to <20% among those aged>40 years. In multivariate analyses, prevalence increased with parity, was lower in married women than in single women, divorcees and widows, and higher in women with the lowest incomes and those professing no religion. Adjusted HIV-1 prevalence increased during 1998 and decreased during 1999. Age modified the effects of parity, home ownership and parental education. Among older women, prevalence was greater for women who were not homeowners. Among younger women, prevalence increased with parity and low parental education. None of these factors distinguished women co-infected with HIV-2 from those infected with HIV-1 alone. Prevalent HIV-1 infection is associated with financial insecurity and weak psychosocial support. The ZVITAMBO study apparently spanned the peak of the HIV-1 epidemic among reproductive women in Harare.

    Single high-dose therapy (HDT) followed by autologous peripheral blood stem cell (PBSC) support improves complete response and overall survival (OS) in untreated aggressive non-Hodgkin's lymphoma (NHL). However, patients with a high age-adjusted international prognostic index (aa-IPI equal to 3) still have poor clinical outcome despite high dose intensity regimen. To improve complete response in this subgroup, the French Groupe Ouest-Est des Leucémies et Autres Maladies du Sang (GOELAMS) conducted a pilot phase II trial (073) evaluating tandem HDT with PBSC support in a series of 45 patients with aa-IPI equal to 3 untreated aggressive non-Hodgkin's lymphoma. After induction with an anthracyclin-containing regimen, responders underwent tandem HDT conditioned by high-dose mitoxantrone plus cytarabine for the first HDT and total-body irradiation (TBI), carmustine, etoposide, and cyclophosphamide for the second HDT. Thirty-one patients out of 41 evaluable patients completed the program. There were 4 toxic deaths. The complete response rate was 49%. With a median follow-up of 114 months for surviving patients, the OS was 51%, and 19 out of the 22 patients (86%) who reached a complete response are alive and relapse-free. Recent prospective evaluation of quality of life and comorbidities of surviving patients does not reveal long-term toxicities of the procedure. In the era of monoclonal antibodies and response-adapted therapy, the role of tandem HDT still need to be determined.

    Objective To estimate the age-adjusted prevalence of general and centralized obesity among Chinese men living in urban Shanghai. Research Methods and Procedures A cross-sectional study was conducted in 61,582 Chinese men aged 40 to 75. Body mass index (BMI, kg/m2) was used to measure overweight (23≤BMI<27.5) and obesity (BMI≥27.5) based on the WHO recommended criteria for Asians. Waist-to-hip ratio (WHR) was used to measure moderate (75th≤WHR<90th percentile) and severe (WHR≥90th percentile) centralized obesity. Results The average BMI and WHR were 23.7 kg/m2 and 0.90, respectively. The prevalence of overweight was 48.6% and obesity, 10.5%. The prevalence of general and centralized obesity was higher in men with high income or who were unemployed, tea drinkers, or non-ginseng users than their counterparts. Men with high education had a higher prevalence of overweight and centralized obesity, but had a lower prevalence of obesity and severe centralized obesity compared to those with lower education. Current smokers or alcohol drinkers had a lower prevalence of general obesity but higher prevalence of centralized obesity than non-smokers or non-alcohol drinkers. Ex-smokers and ex-alcohol drinkers had a higher prevalence of general and centralized obesity compared to non-smokers and non-alcohol drinkers. Prevalence of obesity was associated with high energy intake and low daily physical activity. Conclusions The prevalence of obesity in Chinese men in urban Shanghai was lower than that observed in Western countries but higher than that in other Asian countries, and the prevalence of general and centralized obesity differed by demographic, lifestyle, and dietary factors.

    Objective To estimate the incidence and prevalence of systemic lupus erythematosus (SLE) in a sociodemographically diverse southeastern Michigan source population of 2.4 million people. Methods SLE cases fulfilling the American College of Rheumatology classification criteria (primary case definition) or meeting rheumatologist-judged SLE criteria (secondary definition) and residing in Wayne or Washtenaw Counties during 2002–2004 were included. Case finding was performed from 6 source types, including hospitals and private specialists. Age-standardized rates were computed, and capture–recapture was performed to estimate underascertainment of cases. Results The overall age-adjusted incidence and prevalence (ACR definition) per 100,000 persons were 5.5 (95% confidence interval [95% CI] 5.0–6.1) and 72.8 (95% CI 70.8–74.8). Among females, the incidence was 9.3 per 100,000 persons and the prevalence was 128.7 per 100,000 persons. Only 7 cases were estimated to have been missed by capture–recapture, adjustment for which did not materially affect the rates. SLE prevalence was 2.3-fold higher in black persons than in white persons, and 10-fold higher in females than in males. Among incident cases, the mean ± SD age at diagnosis was 39.3 ± 16.6 years. Black SLE patients had a higher proportion of renal disease and end-stage renal disease (ESRD) (40.5% and 15.3%, respectively) as compared to white SLE patients (18.8% and 4.5%, respectively). Black patients with renal disease were diagnosed as having SLE at younger age than white patients with renal disease (mean ± SD 34.4 ± 14.9 years versus 41.9 ± 21.3 years; P = 0.05). Conclusion SLE prevalence was higher than has been described in most other population-based studies and reached 1 in 537 among black female persons. There were substantial racial disparities in the burden of SLE, with black patients experiencing earlier age at diagnosis, >2-fold increases in SLE incidence and prevalence, and increased

    This cross-sectional study was performed to investigate the reference values for bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA) and the prevalence of osteoporosis in the Korean population by applying domestic reference data. In total, 25,043 Korean adults ≥20 yr of age (11,792 men and 13,251 women) participated in the study. The BMDs of the total hip, femoral neck, and lumbar spine were measured by DXA (Discovery-W, Hologic Inc.), and subjects with a BMD - 2.5 standard deviations or lower than the mean BMD for young adults (20-29 yr old) were considered to have osteoporosis. When applying the new reference values determined in this study from Korean subjects, the overall prevalence of osteoporosis increased in men aged ≥50 yr compared with that provided by the DXA manufacturer from Japanese subjects (12.2% vs. 7.8%, P<0.001) and decreased in postmenopausal women aged ≥50 yr (32.9% vs. 38.7%, P<0.001). According to the findings of this study, use of the reference values provided by the DXA manufacturer has resulted in the underdiagnosis of osteoporosis in Korean men and the overdiagnosis of osteoporosis in Korean women. Our data will serve as valuable reference standards for the diagnosis and management for osteoporosis in the Korean population.

    Background In Mexico, as in other developing countries, micronutrient deficiencies are common in infants between 6 and 24 months of age and are an important public health problem. The objective of this study was to determine the prevalence of anemia and of iron, folic acid, and zinc deficiencies in Mexican children under 2 years of age who use the health care services provided by the Mexican Institute for Social Security (IMSS). Methods A nationwide survey was conducted with a representative sample of children younger than 2 years of age, beneficiaries, and users of health care services provided by IMSS through its regular regimen (located in urban populations) and its Oportunidades program (services offered in rural areas). A subsample of 4,955 clinically healthy children was studied to determine their micronutrient status. A venous blood sample was drawn to determine hemoglobin, serum ferritin, percent of transferrin saturation, zinc, and folic acid. Descriptive statistics include point estimates and 95% confidence intervals for the sample and projections for the larger population from which the sample was drawn. Results Twenty percent of children younger than 2 years of age had anemia, and 27.8% (rural) to 32.6% (urban) had iron deficiency; more than 50% of anemia was not associated with low ferritin concentrations. Iron stores were more depleted as age increased. Low serum zinc and folic acid deficiencies were 28% and 10%, respectively, in the urban areas, and 13% and 8%, respectively, in rural areas. The prevalence of simultaneous iron and zinc deficiencies was 9.2% and 2.7% in urban and rural areas. Children with anemia have higher percentages of folic acid deficiency than children with normal iron status. Conclusion Iron and zinc deficiencies constitute the principal micronutrient deficiencies in Mexican children younger than 2 years old who use the health care services provided by IMSS. Anemia not associated with low ferritin values was more prevalent than

    The prevalence of skin mycoses in the elderly remains unclear. The proportion of people with skin eruptions who are positive for mycoses using direct microscopy is not known. The purpose of this study is to identify the prevalence of skin eruptions and skin mycoses (e.g. candidiasis and tinea) in the buttocks and feet, which are common sites of skin mycoses in residents of long-term care facilities. This multi-site cross-sectional study used visual inspection and direct microscopy to diagnose the type of skin eruption. Subjects were residents of facilities covered by long-term care insurance schemes in Japan. Of the 171 residents enrolled in this study, 72.5% had a skin eruption. Only 4.8% of participants had tinea in the buttocks; 2.4% had buttock candidiasis. In those with a nail abnormality, 58.3% of residents had tinea unguium. For tinea pedis, residents who had any form of interdigital or plantar region skin eruption, 22.5% and 31.4% of residents were positive, respectively. The prevalence of observed skin mycoses was: buttock candidiasis 1.8%; buttock tinea 3.5%; tinea unguium 56.2%; interdigital tinea pedis 20.5%; and plantar tinea pedis 22.5%. The very low proportion of residents with mycoses in the buttocks suggests that anti-inflammatory agents, such as steroids, should be used as first choice. Our observation that not all residents with skin eruptions on the feet had tinea, should remind clinicians to perform direct microscopy before initiating antifungal treatments.

    Cigarette smoking and the use of smokeless tobacco both cause substantial morbidity and premature mortality. The concurrent use of these products might increase dependence and the risk for tobacco-related disease and death. State-specific estimates of prevalence and relative percent change in current cigarette smoking, smokeless tobacco use, and concurrent cigarette smoking and smokeless tobacco use among U.S. adults during 2011-2013, developed using data from the Behavioral Risk Factor Surveillance System (BRFSS), indicate statistically significant (p<0.05) changes for all three behaviors. From 2011 to 2013, there was a statistically significant decline in current cigarette smoking prevalence overall and in 26 states. During the same period, use of smokeless tobacco significantly increased in four states: Louisiana, Montana, South Carolina, and West Virginia; significant declines were observed in two states: Ohio and Tennessee. In addition, the use of smokeless tobacco among cigarette smokers (concurrent use) significantly increased in five states (Delaware, Idaho, Nevada, New Mexico, and West Virginia). Although annual decreases in overall cigarette smoking among adults in the United States have occurred in recent years, there is much variability in prevalence of cigarette smoking, smokeless tobacco, and concurrent use across states. In 2013, the prevalence ranged from 10.3% (Utah) to 27.3% (West Virginia) for cigarette smoking; 1.5% (District of Columbia and Massachusetts) to 9.4% (West Virginia) for smokeless tobacco; and 3.1% (Vermont) to 13.5% (Idaho) for concurrent use. These findings highlight the importance of sustained comprehensive state tobacco-control programs funded at CDC-recommended levels, which can accelerate progress toward reducing tobacco-related disease and deaths by promoting evidence-based population-level interventions. These interventions include increasing the price of tobacco products, implementing comprehensive smoke-free laws

    To examine the relationship between measures of mother's caretaking, practice and individual agency on acute diarrhea and respiratory tract infections (ARTIs) of Indonesian children. Using population-based household data from the Indonesian Demographic Health Surveys for 2002-2003 (n = 9,151 children) and 2007 (n = 9,714 children), we selected 28 indicators related to mother' caretaking, and applied principal component analysis to derive indices for access to care, practice and experience, and agency. The association between index quartiles (level 1-4) and the prevalence of diarrhea and ARTIs in the youngest child <5 years of age was assessed with multivariate logistic regression adjusting for socioeconomic status, residence type, mother's age and education, family size, child's age and sex, immunization status and received vitamin A supplementation. Moderate levels (level 3) of practice and experience were associated with decreased diarrheal risk (adjusted OR 0.86, 95 % CI 0.75-0.98), but not for ARTIs. Children of mothers with higher levels (level 4) of agency were protected against both diarrhea (adjusted OR 0.68, 95 % CI 0.60-0.77) and ARTIs (adjusted OR 0.77, 95 % CI 0.66-0.91). Stratified analyses with child's age and mother's education, and tests of interaction, showed that agency had a stronger effect on diarrhea and ARTIs prevalence in children <2 years of age. Maternal caretaking, especially agency, is strongly associated with lower prevalence of diarrhea and ARTIs in younger children. Interventions specifically designed to promote maternal autonomy and decision-making may lead to improved child health.

    Periodontitis and type 2 diabetes mellitus are known to be associated. The relationship between periodontal microbiota and early diabetes risk has not been studied. We investigated the association between periodontal bacteria and prediabetes prevalence among diabetes-free adults. ORIGINS (the Oral Infections, Glucose Intolerance and Insulin Resistance Study) cross sectionally enrolled 300 diabetes-free adults aged 20 to 55 y (mean ± SD, 34 ± 10 y; 77% female). Prediabetes was defined as follows: 1) hemoglobin A1c values ranging from 5.7% to 6.4% or 2) fasting plasma glucose ranging from 100 to 125 mg/dL. In 1,188 subgingival plaque samples, 11 bacterial species were assessed at baseline, including Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, and Actinomyces naeslundii. Full-mouth clinical periodontal examinations were performed, and participants were defined as having no/mild periodontitis vs. moderate/severe periodontitis per the definition of the Centers for Disease Control and Prevention / American Academy of Periodontology. Modified Poisson regression evaluated prediabetes prevalence across bacterial tertiles. Prevalence ratios and 95% confidence intervals for third vs. first tertiles are presented. All analyses were adjusted for cardiometabolic risk factors. All results presented currently arise from the baseline cross section. Prediabetes prevalence was 18%, and 58% of participants had moderate/severe periodontitis. Prevalence ratios (95% confidence intervals) summarizing associations between bacterial levels and prediabetes were as follows: A. actinomycetemcomitans, 2.48 (1.34, 4.58), P = 0.004; P. gingivalis, 3.41 (1.78, 6.58), P = 0.0003; T. denticola, 1.99 (0.992, 4.00), P = 0.052; T. forsythia, 1.95 (1.0, 3.84), P = 0.05; A. naeslundii, 0.46 (0.25, 0.85), P = 0.01. The prevalence ratio for prediabetes among participants with moderate/severe vs. no/mild periodontitis was 1.47 (0.78, 2.74), P

Using the hemmagglutination inhibition test, we found a 98% prevalence of anti-rubella antibodies among pregnant women in Córdoba and of 96% among the women in Villa Mercedes, whereas the prevalence of anti-parvovirus 819 was 66% in the serum samples from Cordoba. These results coincide with those reported for other cities in the world, and establish an interest in continuing similar studies in order to monitor the immunization plan, which in Argentina has been going on since 1997. They also suggest the importance of the determination of IgM anti-parvovirus B19 in pregnant women who are symptomatic but with a negative result for rubella.
