    The aim of the present study was to report the usual nutrient intakes of sixteen micronutrients by schoolchildren, adults and the elderly in Greece and to further explore the role of age, sex and socio-economic status (SES) on meeting the recommended nutrient intakes. Dietary intake, demographic and SES data from three existing studies conducted in Greece (in 9–13-year-old children; 40–60-year-old adults; and 50–75-year-old women) were collected. The prevalence of study participants with inadequate micronutrient intakes were assessed using the estimated average requirement (EAR) cut-point method. Regarding sex and age differences, the highest prevalences of inadequate nutrient intakes occurred in post-menopausal women. In both sexes and all age groups, the prevalence of vitamin D intake below EAR reached 100%. Furthermore, nutrient intakes of 75% or more below EAR were found for vitamin E in all age groups, folate in women and for calcium and magnesium in post-menopausal women (p < 0.05). Regarding SES differences, the prevalences of inadequate calcium and vitamin C intakes were higher for children and postmenopausal women of lower SES compared to their higher SES counterparts (p < 0.05). The current study reported the highest prevalences of inadequate intakes for both sexes and all age and SES groups for calcium, folate and vitamins D and E. These findings could provide guidance to public health policy makers in terms of updating current dietary guidelines and fortifying foods to meet the needs of all population subgroups. PMID:25285410

    Socio-economic gradients in diet quality are well established. However, the influence of material socio-economic conditions particularly in childhood, and the use of multiple disaggregated socio-economic measures on diet quality have been little studied in the elderly. In the present study, we examined childhood and adult socio-economic measures, and social relationships, as determinants of diet quality cross-sectionally in 4252 older British men (aged 60-79 years). A FFQ provided data on daily fruit and vegetable consumption and the Elderly Dietary Index (EDI), with higher scores indicating better diet quality. Adult and childhood socio-economic measures included occupation/father's occupation, education and household amenities, which combined to create composite scores. Social relationships included social contact, living arrangements and marital status. Both childhood and adult socio-economic factors were independently associated with diet quality. Compared with non-manual social class, men of childhood manual social class were less likely to consume fruit and vegetables daily (OR 0.80, 95% CI 0.66, 0.97), as were men of adult manual social class (OR 0.65, 95% CI 0.54, 0.79), and less likely to be in the top EDI quartile (OR 0.73, 95% CI 0.61, 0.88), similar to men of adult manual social class (OR 0.66, 95 % CI 0.55, 0.79). Diet quality decreased with increasing adverse adult socio-economic scores; however, the association with adverse childhood socio-economic scores diminished with adult social class adjustment. A combined adverse childhood and adulthood socio-economic score was associated with poor diet quality. Diet quality was most favourable in married men and those not living alone, but was not associated with social contact. Diet quality in older men is influenced by childhood and adulthood socio-economic factors, marital status and living arrangements.

    The Survey of Sugar Intake among Children in Scotland was carried out in May to September 2006. The present study aimed to identify dietary patterns in school-aged children from the survey and investigate associations with socio-economic factors, obesity and physical activity. Habitual diet was assessed using the Scottish Collaborative Group FFQ. Height and weight were measured by trained fieldworkers. A total of 1233 FFQ were available for analysis. Dietary patterns were identified by age (5-11 and 12-17 years) and sex using principal components analysis. Associations between factor scores and socio-economic status, education level of the main food provider, physical activity levels and BMI category (based on UK 1990 charts) were examined. Three dietary patterns were identified in each age and sex group. 'Healthier' patterns loading highly for fruit and vegetables were significantly associated with higher socio-economic status and higher education levels of the main food provider whereas more 'unhealthy' patterns ('snacks' and 'puddings') were associated with lower socio-economic status and lower education levels of the main food provider. There was no consistent association between dietary patterns and BMI group or time spent in physical activity. However, inactivity (screen time) was inversely associated with 'healthier' patterns in all age and sex groups and positively associated with 'puddings' and 'snacks' in girls aged 5-11 years. Clear dietary patterns can be identified in school-age children in Scotland, which are consistently related to socio-economic factors and inactivity. This has implications for targeting health promotion at subgroups in terms of lifestyle changes required.

    The present focus is mostly laid on high risk behavior of commercial sex workers without any consideration of their location, educational status and other socio-cultural norms. Thus, we designed a study to understand socio demographic characteristics, lifestyle of female sex workers and search for driving factors for prostitution in eastern Nepal. A descriptive study was conducted in three districts of Eastern Nepal in 2012 over the period of six months. The data regarding their socio demographic characteristics, income, reason for joining sex trade and future choice regarding the profession were recorded from 210 female sex workers through face-to-face interviews. Majority (53.3%) of respondents belonged to the productive age group of 20-29 years, more than one thirds (43.3%) had not received any form of formal education and were unmarried. More than half (53.80%) were presently living alone and about one thirds of the women (31.90%) were minors when they joined this profession. Major portion of the sample (94.80%) worked more than three days a week with median income of 15 thousand per month and 41 percent had sex with more than or equal to ten clients per week. Poor economic condition was the most frequent (47.6%) factor leading to joining of sex trade however, more than two thirds, (72.80%) wanted to quit the profession. Given low level of education, relatively low income, and young age among this population, empowerment and alternative employment/education opportunities should be created to develop this part of Nepalese society.

    Socio-economic conditions during early life are known to affect later life outcomes such as health or social success. We investigated whether family socio-economic background may also affect facial attractiveness. We used the Wisconsin Longitudinal Study (n = 8434) to analyze the association between an individual's parental socio-economic background (in terms of father's highest education and parental income) and that individual's facial attractiveness (estimated by rating of high school yearbook photographs when subjects were between 17 and 20 years old), controlling for subjects' sex, year of birth, and father's age at subjects' birth. Subjects' facial attractiveness increased with increasing father's highest educational attainment as well as increasing parental income, with the latter effect being stronger for female subjects as well. We conclude that early socio-economic conditions predict, to some extent, facial attractiveness in young adulthood.

    The aim was to analyze prevailing oral hygiene practices among urban Saudi Arabians in relation to age, gender, and socio-economic background. Structured interviews were performed with 1155 regular patients at two centers providing dental care for university and military staff and their families, respectively, in the city of Makkah. Consecutive patients were stratified according to gender and age into 6 age categories from 10 to 60 years, with 50 male or female subjects in each group at each center. Oral hygiene habits were correlated with the subject's age and gender, and analyzed statistically using a generalized linear model. It was found that 73% used a toothbrush daily, while a miswak was used daily by 65%. Significant differences were found between genders and age groups, and between the centers. Regular miswak use was more prevalent among men (P < 0.01), while women used toothbrush more than miswak (P < 0.05). Regular miswak use was more frequent at older age (P < 0.001) and tooth brushing was less prevalent. Forty-four percent of the 51- to 60-year-old patients at the military center never used a toothbrush. Regular toothbrush use was more prevalent in the youngest age groups (P < 0.001). Among the 10- to 15-year-olds, 45% at the university center used only a toothbrush, while no adolescents at the military center used only a toothbrush. We conclude that there are large differences in current oral hygiene habits among Saudi Arabians, and that these are related mainly to age and socio-economic level, and to a lesser extent gender. This should be taken into account when planning oral health strategies for different categories.

  9. Socio-economic differentials in birth masculinity in China.

    2011-01-01

    This article examines the relationship between birth masculinity and socio-economic levels in China. Both 2000 and 2005 data suggest the presence of a non-linear relationship between the sex ratio at birth and socio-economic status, with a lower sex ratio at birth observed among both the poorest and the richest households. This inverted-U pattern is significantly different from what is observed in India and what has been assumed previously for China. Multivariate analyses indicate that this pattern persists after the introduction of several other covariates of birth masculinity such as ethnicity, fertility, migration status, age or parity. These results suggest that further economic advances and socio-economic mobility could contribute to the return to normalcy of the sex ratio at birth.

    In recent decades many industrialized countries experienced a substantial decrease in the working age population as a proportion of the total population. Demographic factors, such as declining fertility and increasing life expectancy, as well as institutional factors, such as the generosity of state-funded pension, both determined a change in the age distribution and a marked anticipation in retirement age. A lively debate among researchers and policymakers is currently taking place in Europe, as there are concerns that working longer may not be healthy for workers, or that it will be hard for older workers to get a job. Conversely, if working longer leads to higher employment rates and better health conditions, policies aimed at increasing peoples' retirement age may represent a "win-win" strategy both in terms of fiscal policies as well as in terms of healthy life expectancy. Unfolding this controversy is essentially an empirical matter which is also of paramount importance for public policy. In this study we first review the main findings of the socio-economic literature. Second, we highlight the main research avenues that are currently investigated in the area of Social Science and Health Economics at the Universitá Cattolica. Finally we discuss the policy implications and the prospects for future research.

    Orthodontic treatment is a common dental procedure in developed countries. However, the frequency and factors associated with treatment demand are different between countries. The aim of this study was to examine the frequency of orthodontic treatment in German children and adolescents and to analyse the influence of age, gender, and socio-economic status (SES; education and region) on the frequency of treatment. Subjects in a random population sample of 1538 German children and adolescents, aged 11-14 years, were interviewed at home in the autumn of 2008 regarding current orthodontic treatment and associated factors. Approximately one-third (33.5 per cent) of the subjects interviewed were undergoing orthodontic treatment at that time. In a multivariable logistic regression model, the likelihood of receiving orthodontic treatment was higher for girls [odds ratio (OR) = 1.32, 95 per cent confidence interval (CI): 1.06-1.65], for high school pupils (OR = 1.19, 95 per cent CI: 1.06-1.34), and for children and adolescents living in the western part of Germany (OR = 1.45, 95 per cent CI: 1.00-2.08) and increased with age (OR = 1.13 per year, 95 per cent CI: 1.02-1.25). Subjects undergoing orthodontic treatment more often received prophylactic measures (OR = 2.06, 95 per cent CI: 1.63-2.59) compared with those not currently receiving orthodontic treatment. The frequency of orthodontic treatment in Germany largely depends on gender and SES.

  12. Aging in Asia: a cultural, socio-economical and historical perspective.

    PubMed

    Goh, Victor H H

    2005-06-01

    Asia has about 60% of the world population and population aging is occurring more rapidly in Asia than in Western countries. The group aged 65 years and above will increase from 207 million in 2000 to 857 million in 2050, a staggering increase of 314%. The diversity in economic, demographic, religious, cultural and geo-political factors in Asia is unparalleled by any other continent, and is, in part, contributory to the rapid rise in population aging. By 2050, those under 15 years old will have shrunk from 30% in 2000 to 19%, while those aged 65 years and above will increase from 6% to 18%. In addition, the gender divide still persists with 100 elderly women to 70 elderly men. These projected demographic changes pose three major challenges: 1) how best to address the rising population of the group aged 65 years and above, 2) how to address the shrinking population of the young as well as the working adults, and 3) how to address the problems arising from the disproportionate increase in older women than men. From now to 2050, it will be expeditious for each country in Asia to look into ways of reversing the decline in total fertility rates (TFRs) and restore to replacement levels. If not, at least introduce measures to halt its free fall. Due to the complexity of factors that have influenced the fall in TFRs in Asia, it will be a daunting task to reverse this fall. There is no "single size fits all" solution to this complex problem. Research work in this short-term strategy in addressing the aging population is urgent. In the longer term, the East-West Centre have suggested four modalities, 1) establish policies and programmes that enhance traditional Asian systems of family support for the elderly; 2) introduce policy reform that encourages the elderly who are still capable of remaining in the work force; 3) create institutions and systems that support high levels of personal saving; and 4) formulate public programmes, including pension schemes and national

  14. Desirable rights: same-sex sexual subjectivities, socio-economic transformations, global flows and boundaries--in India and beyond.

    PubMed

    Boyce, Paul

    2014-01-01

    Sexual rights are increasingly and unevenly advanced internationally as constitutive of progressive legal possibilities for same-sex desiring subjects. Legislative progress in this area has taken place in the context of recognition of same-sex sexual subjects within the globalising flow of neo-liberal political-economic ideologies in some parts of the word, and resurgent homophobia as a countervailing trend elsewhere (or indeed even within the same context). Ambivalent responses to sexual rights praxis in people's day-to-day lives indicate complex relationships between sexual subjectivity, economy, law, the state, and people's most intimate aspirations. Rights on grounds of same-sex sexualities may or may not be perceived as universally desirable, even among those people who might otherwise be imagined as their beneficiaries. Given this, the relationship between sexual subjectivities, political economies, and rights must be understood in terms of multifaceted refractions, attending to generative and curtailing possibilities--imagined in people's differing responses to free-market capital, legislation, and possibilities for livelihood. These issues are explored in respect of ethnographic work in West Bengal, India, with a particular focus on male-bodied subjects who evince both masculine and feminine subjectivities, and in respect of recent contestations in law, polity, and sexual rights praxis.

    Individual-level data from the Florida Cancer Data System (1981–2007) were analysed to explore temporal trends of prostate cancer late-stage diagnosis, and how they vary based on race, income and age. Annual census-tract rates were computed for two races (white and black) and two age categories (40–65, >65) before being aggregated according to census tract median household incomes. Joinpoint regression and a new disparity statistic were applied to model temporal trends and detect potential racial and socio-economic differences. Multi-dimensional scaling was used as an innovative way to visualize similarities among temporal trends in a 2-D space. Analysis of time-series indicated that late-stage diagnosis was generally more prevalent among blacks, for age category 40–64 compared to older patients covered by Medicare, and among classes of lower socio-economic status. Joinpoint regression also showed that the rate of decline in late-stage diagnosis was similar among older patients. For younger patients, the decline occurred at a faster pace for blacks with rates becoming similar to whites in the late 90s, in particular for higher incomes. Both races displayed distinct spatial patterns with higher rates of late-stage diagnosis in the Florida Panhandle for whites whereas high rates clustered in South-eastern Florida for blacks.

  17. The influence of age, gender and socio-economic status on multimorbidity patterns in primary care. first results from the multicare cohort study

    PubMed Central

    2012-01-01

    Background Multimorbidity is a phenomenon with high burden and high prevalence in the elderly. Our previous research has shown that multimorbidity can be divided into the multimorbidity patterns of 1) anxiety, depression, somatoform disorders (ADS) and pain, and 2) cardiovascular and metabolic disorders. However, it is not yet known, how these patterns are influenced by patient characteristics. The objective of this paper is to analyze the association of socio-demographic variables, and especially socio-economic status with multimorbidity in general and with each multimorbidity pattern. Methods The MultiCare Cohort Study is a multicentre, prospective, observational cohort study of 3.189 multimorbid patients aged 65+ randomly selected from 158 GP practices. Data were collected in GP interviews and comprehensive patient interviews. Missing values have been imputed by hot deck imputation based on Gower distance in morbidity and other variables. The association of patient characteristics with the number of chronic conditions is analysed by multilevel mixed-effects linear regression analyses. Results Multimorbidity in general is associated with age (+0.07 chronic conditions per year), gender (-0.27 conditions for female), education (-0.26 conditions for medium and -0.29 conditions for high level vs. low level) and income (-0.27 conditions per logarithmic unit). The pattern of cardiovascular and metabolic disorders shows comparable associations with a higher coefficient for gender (-1.29 conditions for female), while multimorbidity within the pattern of ADS and pain correlates with gender (+0.79 conditions for female), but not with age or socioeconomic status. Conclusions Our study confirms that the morbidity load of multimorbid patients is associated with age, gender and the socioeconomic status of the patients, but there were no effects of living arrangements and marital status. We could also show that the influence of patient characteristics is dependent on the

    Street littering is considered an important environmental health issue in the Middle East. This problem is growing steadily and is attracting great concerns within the communities. The purpose of this paper, which focuses on Nablus district (Palestinian Territory), is to measure the perception and opinion of residents toward littering, in addition to studying prevailing attitudes and practices on littering. This was achieved using an interview survey approach. The influence of three socio-economic factors; level of education, age, and type of residence, on the littering behaviour of individuals was studied. As a result, possible remedial actions have been suggested. The data presented in this work can be considered as one piece of information, which can be compiled with other future data to design an effective litter control programrhe for Middle Eastern countries.

    Poor feeding practices among young children lead to malnutrition, and the poor are at a greater risk than the better off groups. Child-feeding practices in various socio-economic strata, especially in urban settings, have not yet been well studied in Indonesia. This study aims to explore the feeding practices of 12-23 months old children from different socio-economic status (SES) groups. A cross-sectional survey was conducted, which included low (n 207), medium-high (n 205), medium-low (n 208) and high SES households (n 194) in forty-three villages within thirty-three sub-districts of Bandung city. Two non-consecutive 24 h recall and eight core indicators of child-feeding practices were assessed through interviews. The results showed that children from the high SES group were more likely to be exclusively breast-fed and to continue breast-feeding up to 1 year of age, met minimum dietary diversity and minimum acceptable diet, and also consumed Fe-rich or Fe-fortified foods. In contrast, children from low SES consumed more energy-rich food (grain) but fewer foods from the other food groups. Consumption of major nutrients differed across the SES groups. Inadequate nutrition was higher among children from the lower SES groups. Fortified foods were consumed by a larger proportion of children from the high SES group and contributed considerably to their overall nutrient intake. This study shows that young children's feeding practices were not adequate, most notably among the low SES households. However, after adjusting with potential confounders, there was not enough evidence to conclude SES as a risk factor for feeding practice.

    2013-01-01

    Background Micronutrient deficiencies (MNDs) are a chronic lack of vitamins and minerals and constitute a huge public health problem. MNDs have severe health consequences and are particularly harmful during early childhood due to their impact on the physical and cognitive development. We estimate the costs of illness due to iron deficiency (IDA), vitamin A deficiency (VAD) and zinc deficiency (ZnD) in 2 age groups (6–23 and 24–59 months) of Filipino children by socio-economic strata in 2008. Methods We build a health economic model simulating the consequences of MNDs in childhood over the entire lifetime. The model is based on a health survey and a nutrition survey carried out in 2008. The sample populations are first structured into 10 socio-economic strata (SES) and 2 age groups. Health consequences of MNDs are modelled based on information extracted from literature. Direct medical costs, production losses and intangible costs are computed and long term costs are discounted to present value. Results Total lifetime costs of IDA, VAD and ZnD amounted to direct medical costs of 30 million dollars, production losses of 618 million dollars and intangible costs of 122,138 disability adjusted life years (DALYs). These costs can be interpreted as the lifetime costs of a 1-year cohort affected by MNDs between the age of 6–59 months. Direct medical costs are dominated by costs due to ZnD (89% of total), production losses by losses in future lifetime (90% of total) and intangible costs by premature death (47% of total DALY losses) and losses in future lifetime (43%). Costs of MNDs differ considerably between SES as costs in the poorest third of the households are 5 times higher than in the wealthiest third. Conclusions MNDs lead to substantial costs in 6-59-month-old children in the Philippines. Costs are highly concentrated in the lower SES and in children 6–23 months old. These results may have important implications for the design, evaluation and choice of the

    The prevalence of obesity among Italian children has reached such alarming levels as to require detailed studies of the causes of the phenomenon. A cross-sectional study was carried out in order to assess the weight status of 1164 Italian children aged 6–8 years (the Monitoring Air Pollution Effects on Children for Supporting Public Health Policy (MAPEC_LIFE) cohort) and to identify any associations between selected socio-economic and environmental factors and overweight/obesity. The data were obtained by means of a questionnaire given to parents, and any associations were examined by binomial logistic regression analyses. Overweight was found to be positively associated with male gender, parents of non-Italian origin, and parents who smoke, and negatively associated with the parents’ level of education and employment. In addition, the frequency of overweight varied in relation to the geographical area of residence, with a greater prevalence of overweight children in the cities of central-southern Italy. This study highlights the need to implement appropriate obesity prevention programs in Italy, which should include educational measures concerning lifestyle for parents from the earliest stages of their child’s life.

This study highlights the need to implement appropriate obesity prevention programs in Italy, which should include educational measures concerning lifestyle for parents from the earliest stages of their child's life.

    Childhood overweight and obesity have emerged as a public health concern in sub-Saharan Africa. We conducted a systematic review with the aim to examine the association between socio-economic status (SES) and overweight or obesity among school-age children in sub-Saharan Africa. In March 2014 we searched five electronic databases for reports which presented cross-sectional data on prevalence levels of overweight or obesity stratified by SES groups among school-age children in sub-Saharan Africa. We used a random-effect model to pool the relative indexes of inequality of the association from the individual studies. In total, 20 reports satisfied the inclusion criteria providing results of 21 datasets. The risk of overweight or obesity in children from highest SES households was 5.28 times as high as that of children from lowest SES households (95% confidence interval [CI] 2.62 to 10.66). On subgroup analysis, this association was statistically significant for household income and composite SES measures but not for parental educational attainment and occupation type. Similarly, the risk of overweight or obesity in children attending affluent (private) schools was 15.94 times as high as that of children going to either urban or rural public schools (95% CI 5.82 to 43.68). The magnitude of the association tended to be stronger for area or school-type compared with composite measures. In summary, children from higher SES households and those attending private schools tended to be overweight and obese.

    Different factors like stress and occlusion can decrease the adaptive capacity of the stomatognathic system and lead to the occurrence of temporomandibular dysfunction (TMD). The objective of this study was to verify the relation of the variables socio-economic level, schooling, sex and age with the occurrence of temporomandibular dysfunction. The population of this study consisted of a statistically significant sample of subjects of both sexes belonging to different socio-economic classes living in the urban area of the city of Piacatu, São Paulo, Brazil. The Criterion of Economic Classification Brazil (CCEB) was used for the economic stratification of the population. Fonseca's Questionnaire was applied to samples collected from each extract to verify the level of TMD. The data collected were statistically analyzed using the Chi-square Test, with a significance level of 5%. In total, 354 heads of families participated in the research. No statistically significant relation was found between socio-economic class, schooling, age group and temporomandibular dysfunction (TMD). There was a relation between sex and TMD (p<0.02). The variables socio-economic class, schooling and age group had no influence upon the occurrence of TMD, however there is a significant relation with the sex of the individual.

    School-based, free HPV vaccination for girls in the first year of secondary school was introduced in Flanders (Belgium) in 2010. Before that, non school-based, co-payment vaccination for girls aged 12-18 was in place. We compared vaccination coverage, age-specific coverage and socio-economic inequalities in coverage - 3 important parameters contributing to the effectiveness of the vaccination programs - under both vaccination systems. We used retrospective administrative data from different sources. Our sample consisted of all female members of the National Alliance of Christian Mutualities born in 1995, 1996, 1998 or 1999 (N=66,664). For each vaccination system we described the cumulative proportion HPV vaccination initiation and completion over time. We used life table analysis to calculate age-specific rates of HPV vaccination initiation and completion. Analyses were done separately for higher income and low income groups. Under non school-based, co-payment vaccination the proportions HPV vaccination initiation and completion slowly rose over time. By age 17, the proportion HPV vaccination initiation/completion was 0.75 (95% CI 0.74-076)/0.66 (95% CI 0.65-0.67). The median age at vaccination initiation/completion was 14.4 years (95% CI 14.4-14.5)/15.4 years (95% CI 15.3-15.4). Socio-economic inequalities in coverage widened over time and with age. Under school-based, free vaccination rates of HPV vaccination initiation were substantially higher. By age 14,the proportion HPV vaccination initiation/completion was 0.90 (95% CI 0.90-0.90)/0.87 (95% CI 0.87-0.88). The median age at vaccination initiation/completion was 12.7 years (95% CI 12.7-12.7)/13.3 years (95% CI 13.3-13.3). Socio-economic inequalities in coverage and in age-specific coverage were substantially smaller.

    Socio-economic groups differ in their material, living, working and social circumstances, which may result in different priorities about their daily-life needs, including the priority to make healthy food choices. Following Maslow's hierarchy of human needs, we hypothesised that socio-economic inequalities in healthy food choices can be explained by differences in the levels of need fulfilment. Postal survey data collected in 2011 (67·2 % response) from 2903 participants aged 20-75 years in the Dutch GLOBE (Gezondheid en Levens Omstandigheden Bevolking Eindhoven en omstreken) study were analysed. Maslow's hierarchy of human needs (measured with the Basic Need Satisfaction Inventory) was added to age- and sex-adjusted linear regression models that linked education and net household income levels to healthy food choices (measured by a FFQ). Most participants (38·6 %) were in the self-actualisation layer of the pyramid. This proportion was highest among the highest education group (47·6 %). Being in a higher level of the hierarchy was associated with a higher consumption of fruits and vegetables as well as more healthy than unhealthy bread, snack and dairy consumption. Educational inequalities in fruit and vegetable intake (B= -1·79, 95 % CI -2·31, -1·28 in the lowest education group) were most reduced after the hierarchy of needs score was included (B= -1·57, 95 % CI - ·09, -1·05). Inequalities in other healthy food choices hardly changed after the hierarchy of needs score was included. People who are satisfied with higher-level needs make healthier food choices. Studies aimed at understanding socio-economic inequalities in food choice behaviour need to take differences in the priority given to daily-life needs by different socio-economic groups into account, but Maslow's pyramid offers little help.

    Understanding the links between bone microstructure and human lifestyle is critical for clinical and anthropological research into skeletal growth and adaptation. The present study is the first to report correspondence between socio-economic status and variation in bone microstructure in ancient humans. Products of femoral cortical remodeling were assessed using histological methods in a large human medieval sample (N = 450) which represented two distinct socio-economic groups. Osteonal parameters were recorded in posterior midshaft femoral sections from adult males (N = 233) and females (N = 217). Using univariate and multivariate statistics, intact, fragmentary, and osteon population densities, Haversian canal area and diameter, and osteon area were compared between the two groups, accounting for sex, age, and estimated femoral robusticity. The size of osteons and their Haversian canals, as well as osteon density, varied significantly between the socio-economic groups, although minor inconsistencies were observed in females. Variation in microstructure was consistent with historical textual evidence that describes differences in mechanical loading and nutrition between the two groups. Results demonstrate that aspects of ancient human lifestyle can be inferred from bone microstructure.

    Two hundred and four patients who underwent renal transplantation were followed up as outpatients with a minimum of four years. They were divided into two socio-economic levels: group I - 104 patients who underwent transplantation in a private hospital and 120 patients (group II) with a lower socio-economic standard, treated in a public hospital. In both groups urinary infections and hepatitis were excluded. The incidence of infection in group I was 24% and in group II, 50% (p = 0.0002). There was no difference in relation to viral infection in either groups. However, bacterial infection and infection by opportunistic agents were significantly higher in group II (p = 0.0001 and p = 0.0282). The number of hospitalizations and the number of infections of patients were higher in group II. There was a tendency for an increase in mortality owing to infection in group II. There was no difference in the two groups as the parameters of: age, sex, type of donor, primary disease, number of rejections crises, level of serum creatinine and number of patients with ciclosporine. On the other hand, the dose of azathioprine and prednisone was mildly higher in those patients of group II. Low level of socio-economic conditions is a risk factor in renal transplant patients.

    Background Despite abundant evidence that socio-economic status (SES) is a fundamental determinant of health, there is a dearth of research examining association between SES, measured at the individual and community levels, and cardiovascular risk factors and morbidity among indigenous populations. Objectives To examine the influence of individual-level and community-level SES on systolic and diastolic blood pressure among Greenlandic Inuit. Methods Multilevel analysis of cross-sectional data from the Inuit Health in Transition – Greenland Survey, to which 3,108 Greenlandic Inuit aged 18 years and older participated. Blood pressure is measured using an automatic device, according to standardized protocol. Individual SES is measured by education. Community socio-economic conditions are measured using combined information on average disposable household income and settlement type. Results Education was not significantly associated with blood pressure. There was an inverse U-shape association between community socio-economic conditions and blood pressure with significantly lower SBP and DBP among participants living in remote traditional villages characterized by lower average disposable household income and in affluent more urbanized towns. Sex-stratified analyses demonstrate the salience of community conditions for men. Conclusions The association observed between blood pressure and community-level socio-economic conditions suggests that public health and social policies, programmes and interventions aiming to improve living conditions might improve cardiovascular health in Greenland. Studies are required to further examine social gradients in cardiovascular risk factors and morbidity among indigenous populations using different measures of SES. PMID:27938632

    Highlights: • We analyse ICT equipment reuse operations of socio-economic enterprises. • Most common ICT products dealt with are computers and related equipment. • In the UK in 2010, ∼143,750 appliances were reused. • Marketing and legislative difficulties are the common hurdles to reuse activities. • Socio-economic enterprises can significantly contribute to resource efficiency. - Abstract: In Europe, socio-economic enterprises such as charities, voluntary organisations and not-for-profit companies are involved in the repair, refurbishment and reuse of various products. This paper characterises and analyses the operations of socio-economic enterprises that are involved in the reuse of Information and Communication Technology (ICT) equipment. Using findings from a survey, the paper specifically analyses the reuse activities of socio-economic enterprises in the UK from which Europe-wide conclusions are drawn. The amount of ICT products handled by the reuse organisations is quantified and potential barriers and opportunities to their operations are analysed. By-products from reuse activities are discussed and recommendations to improve reuse activities are provided. The most common ICT products dealt with by socio-economic enterprises are computers and related equipment. In the UK in 2010, an estimated 143,750 appliances were reused. However, due to limitations in data, it is difficult to compare this number to the amount of new appliances that entered the UK market or the amount of waste electrical and electronic equipment generated in the same period. Difficulties in marketing products and numerous legislative requirements are the most common barriers to reuse operations. Despite various constraints, it is clear that organisations involved in reuse of ICT could contribute significantly to resource efficiency and a circular economy. It is suggested that clustering of their operations into “reuse parks” would enhance both their profile and their

    One of the most common sex chromosomal abnormalities in females is 47,XXX syndrome, which is characterized by tall stature and reduced IQ, but with a variable phenotype. In order to elaborate on the characteristics of this syndrome, we undertook an investigation in all diagnosed 47,XXX females at risk in Denmark and compared their socio-economic status with an age-matched cohort of the female background population as well as with all Danes diagnosed with Turner syndrome. We focused on cohabitation, motherhoods, income, education, retirement and convictions. Furthermore, we investigated whether some of these parameters influenced the increased mortality identified previously. Thus, socio-economic data were retrieved in 108 47,XXX persons, 10,297 controls, and 831 with Turner syndrome. Comparing the 47,XXX persons with their controls, we identified significantly decreased numbers of first partnership, number of mothers, and number of persons with an education in 47,XXX persons. Significantly more 47,XXX persons retired. In the younger age groups an increased number had income below the median among controls. The increased mortality identified previously was not explained by the reduced number of partnerships or the reduced number of persons with an education. Comparing the 47,XXX persons with Turner syndrome persons, we identified increased number of first partnership, number of mothers, and reduced level of education. We hypothesize that the significantly decreased number of 47,XXX persons becoming mothers could be due to hypogonadism in some. The affected socio-economic status suggests that the presence of an extra X chromosome has more detrimental effects than previously appreciated.

    Adequate vegetable and fruit consumption is necessary for preventing nutrition-related diseases. Socio-economically disadvantaged adolescents tend to consume relatively few vegetables and fruits. However, despite nutritional challenges associated with socio-economic disadvantage, a minority of adolescents manage to eat vegetables and fruit in quantities that are more in line with dietary recommendations. This investigation aimed to identify predictors of more frequent intakes of fruits and vegetables among adolescents over a 2-year follow-up period. Data were drawn from 521 socio-economically disadvantaged (maternal education ≤Year 10 of secondary school) Australian adolescents aged 12-15 years. Participants were recruited from 37 secondary schools and were asked to complete online surveys in 2004/2005 (baseline) and 2006/2007 (follow-up). Surveys comprised a 38-item FFQ and questions based on Social Ecological models examining intrapersonal, social and environmental influences on diet. At baseline and follow-up, respectively, 29% and 24% of adolescents frequently consumed vegetables (≥2 times/day); 33% and 36% frequently consumed fruit (≥1 time/day). In multivariable logistic regressions, baseline consumption strongly predicted consumption at follow-up. Frequently being served vegetables at dinner predicted frequent vegetable consumption. Female sex, rarely purchasing food or drink from school vending machines, and usually being expected to eat all foods served predicted frequent fruit consumption. Findings suggest nutrition promotion initiatives aimed at improving eating behaviours among this at-risk population and should focus on younger adolescents, particularly boys; improving adolescent eating behaviours at school; and encouraging families to increase home availability of healthy foods and to implement meal time rules.

    South Korea has the highest suicide rate among countries in the Organisation for Economic Co-operation and Development (OECD), with a rising trend that contrasts with the trend in most other OECD countries. This study assessed differential associations of socio-demographic factors with suicidal ideation in South Korea. We used five waves of data from the 2010 Korea National Health and Nutrition Examination Survey. Study subjects included 5803 men and women aged >25 years. We analysed weighted percentages with consideration of the complex survey sample design and unequal weights. Surveylogistic regressions were applied. Protective effects against suicidal ideation were found for higher household income, higher educational attainment, and being married. Functional limitations and depressive symptoms were risk factors for suicidal ideation. However, these significant factors may exert different effects on vulnerability for suicidal ideation among different genders and age groups. Thus, household income was mainly protective for women and subjects aged 25-44 years, and educational attainment was protective for individuals aged >65 years. Our findings suggest the need for extended social protection policies for the less privileged population and special strategies for different groups.

Reuse parks would also improve consumer confidence in and subsequently sales of the products. Further, it is advocated that industrial networking opportunities for the exchange of by-products resulting from the organisations' activities should be investigated. The findings make two significant contributions to the current literature. One, they provide a detailed insight into the reuse operations

    Birthweights of 3,451 infants of women registered for antenatal care in Uppsala County, Sweden, were analyzed using three different maternal socio-economic indicators; education, socio-economic status and work environment exposure characteristics. Other explanatory variables were maternal age, parity, height, smoking habits, and length of gestation. Mean birthweights increase with longer education and higher socio-economic status. No general pattern was seen for work environment characteristics. When smoking habits are controlled for, social differences in birthweight decrease to non-significant values. A regression model with a socio-economic indicator alone explains only a minor part, less than 1%, of the variation in birthweight. When smoking is included, adding a socio-economic indicator does not significantly improve the model. Practically all social differences in birthweight are related to the differences in maternal age, parity, height, and smoking habits. If a socio-economic indicator is to be included in the analysis of birthweights (for other reasons like international comparisons), we recommend education.

    Background Somatisation disorder can result from an interplay between suboptimal family environment and socio-economic deprivation, which enhances the underlying cognitive tendency for this disorder. There are pertinent familial and socio-economic factors associated with this disorder, but research addressing this is sparse. Aim and setting The study aims to evaluate family and socio-economic factors that are associated with somatisation disorder amongst patients presenting to the Family Medicine clinic, University College Hospital, Ibadan, Nigeria. Methods This is an observational case-control study of 120 participants who presented to the clinic between May and August 2009. Data collection was by interviewer-administered structured questionnaire using the World Health Organization Screener for Somatoform Disorder and Somatoform Disorder Schedule to ascertain somatisation in 60 patients who were then matched with 60 controls. The respondents’ demographic and family data were also collected and their interpersonal relationships were assessed with the Family Relationship Index. Results The somatising patients were mostly females (70%), with a female to male ratio of 2.3:1 and mean age of 43.65 ± 13.04years.Living in a polygamous family (as any member of the family) was significantly related to somatisation (p = 0.04). Somatisation was also more common in people who were separated, divorced or widowed (p = 0.039). Somatisers from a lower social class or those earning below a dollar a day experienced poorer cohesion (p = 0.042) and more conflicts (p = 0.019) in their interpersonal relationship. Conclusion This study was able to demonstrate that a polygamous family setting, disrupted marriage, low social status and financial constraints are correlates of somatisation. It is of essence to identify these factors in holistic management of somatising patients. PMID:26245602

    Socio-economic networks are of central importance in economic life. We develop a method of identifying and studying motifs in socio-economic networks by focusing on “dynamic motifs,” i.e., evolutionary connection patterns that, because of “node acquaintances” in the network, occur much more frequently than random patterns. We examine two evolving bi-partite networks: i) the world-wide commercial ship chartering market and ii) the ship build-to-order market. We find similar dynamic motifs in both bipartite networks, even though they describe different economic activities. We also find that “influence” and “persistence” are strong factors in the interaction behavior of organizations. When two companies are doing business with the same customer, it is highly probable that another customer who currently only has business relationship with one of these two companies, will become customer of the second in the future. This is the effect of influence. Persistence means that companies with close business ties to customers tend to maintain their relationships over a long period of time.

    The aim of this study is to investigate the association of allergic rhinitis in female university students with socio-economic factors and sex-hormone markers, including age at menarche, menstrual disorders, and selected anthropometrics indexes. The research was conducted among 640 female university students, aged 19-25 years. The measurements of body height, body mass, waist and hip circumference were taken. Each person completed a questionnaire. The occurrence of allergy was determined on the basis of answers to the questions whether the allergy and its allergens were defined on the basis of medical workup. We found that a significantly larger number of cases of allergic rhinitis were recorded in the university students coming from families of high socio-economic level than those from lower level. Allergic rhinitis also was more frequent in the students who spent their childhood in cities than in those who lived in the countryside. The prevalence of allergic rhinitis was inversely correlated to the number of siblings. There were no differences in the prevalence of allergic rhinitis in relation to the birth order. The estrogen level seemed unassociated with rhinitis. However, there were slightly more allergic among females with an earlier age of menarche.

    AIM: To evaluate the association between various lifestyle factors and achalasia risk. METHODS: A population-based case-control study was conducted in Northern Ireland, including n = 151 achalasia cases and n = 117 age- and sex-matched controls. Lifestyle factors were assessed via a face-to-face structured interview. The association between achalasia and lifestyle factors was assessed by unconditional logistic regression, to produce odds ratios (OR) and 95% confidence interval (CI). RESULTS: Individuals who had low-class occupations were at the highest risk of achalasia (OR = 1.88, 95%CI: 1.02-3.45), inferring that high-class occupation holders have a reduced risk of achalasia. A history of foreign travel, a lifestyle factor linked to upper socio-economic class, was also associated with a reduced risk of achalasia (OR = 0.59, 95%CI: 0.35-0.99). Smoking and alcohol consumption carried significantly reduced risks of achalasia, even after adjustment for socio-economic status. The presence of pets in the house was associated with a two-fold increased risk of achalasia (OR = 2.00, 95%CI: 1.17-3.42). No childhood household factors were associated with achalasia risk. CONCLUSION: Achalasia is a disease of inequality, and individuals from low socio-economic backgrounds are at highest risk. This does not appear to be due to corresponding alcohol and smoking behaviours. An observed positive association between pet ownership and achalasia risk suggests an interaction between endotoxin and viral infection exposure in achalasia aetiology. PMID:27099443

    Reduced quality of life (QoL) is a known consequence of chronic disease in children, and this association may be more evident in those who are socio-economically disadvantaged. The aims of this systematic review were to assess the association between socio-economic disadvantage and QoL among children with chronic disease, and to identify the specific socio-economic factors that are most influential. MEDLINE, Embase and PsycINFO were searched to March 2015. Observational studies that reported the association between at least one measure of social disadvantage in caregivers and at least one QoL measure in children and young people (age 2-21 years) with a debilitating non-communicable childhood disease (asthma, chronic kidney disease, type 1 diabetes mellitus and epilepsy) were eligible. A total of 30 studies involving 6957 patients were included (asthma (six studies, n = 576), chronic kidney disease (four studies, n = 796), epilepsy (14 studies, n = 2121), type 1 diabetes mellitus (six studies, n = 3464)). A total of 22 (73%) studies reported a statistically significant association between at least one socio-economic determinant and QoL. Parental education, occupation, marital status, income and health insurance coverage were associated with reduced QoL in children with chronic disease. The quality of the included studies varied widely and there was a high risk of reporting bias. Children with chronic disease from lower socio-economic backgrounds experience reduced QoL compared with their wealthier counterparts. Initiatives to improve access to and usage of medical and psychological services by children and their families who are socio-economically disadvantaged may help to mitigate the disparities and improve outcomes in children with chronic illnesses.

    It is well known that socio-economic status is a strong predictor of screening attendance, with women of higher socioeconomic status more likely to attend breast cancer screening. We investigated whether socio-economic status was related to the detection of cancer at breast screening centres. In two separate projects we combined UK data from the population census, the screening information systems, and the cancer registry. Five years of data from all 81 screening centres in the UK was collected. Only women who had previously attended screening were included. The study was given ethical approval by the University of Warwick Biomedical Research Ethics committee reference SDR-232-07- 2012. Generalised linear models with a log-normal link function were fitted to investigate the relationship between predictors and the age corrected cancer detection rate at each centre. We found that screening centres serving areas with lower average socio-economic status had lower cancer detection rates, even after correcting for the age distribution of the population. This may be because there may be a correlation between higher socio-economic status and some risk factors for breast cancer such as nullparity (never bearing children). When applying adjustment for age, ethnicity and socioeconomic status of the population screened (rather than simply age) we found that SDR can change by up to 0.11.

  9. The development of socio-economic health differences in childhood: results of the Dutch longitudinal PIAMA birth cohort

    PubMed Central

    2011-01-01

    Background People with higher socio-economic status (SES) are generally in better health. Less is known about when these socio-economic health differences set in during childhood and how they develop over time. The goal of this study was to prospectively study the development of socio-economic health differences in the Netherlands, and to investigate possible explanations for socio-economic variation in childhood health. Methods Data from the Dutch Prevention and Incidence of Asthma and Mite Allergy (PIAMA) birth cohort study were used for the analyses. The PIAMA study followed 3,963 Dutch children during their first eight years of life. Common childhood health problems (i.e. eczema, asthma symptoms, general health, frequent respiratory infections, overweight, and obesity) were assessed annually using questionnaires. Maternal educational level was used to indicate SES. Possible explanatory lifestyle determinants (breastfeeding, smoking during pregnancy, smoking during the first three months, and day-care centre attendance) and biological determinants (maternal age at birth, birthweight, and older siblings) were analysed using generalized estimating equations. Results This study shows that socio-economic differences in a broad range of health problems are already present early in life, and persist during childhood. Children from families with low socio-economic backgrounds experience more asthma symptoms (odds ratio (OR) 1.27; 95% Confidence Interval (CI) 1.08-1.49), poorer general health (OR 1.36; 95% CI 1.16-1.60), more frequent respiratory infections (OR 1.57; 95% CI 1.35-1.83), more overweight (OR 1.42; 95% CI 1.16-1.73), and more obesity (OR 2.82; 95% CI 1.80-4.41). The most important contributors to the observed childhood socio-economic health disparities are socio-economic differences in maternal age at birth, breastfeeding, and day-care centre attendance. Conclusions Socio-economic health disparities already occur very early in life. Socio-economic

    Whilst high-resolution spatial variables contribute to a good fit of spatially explicit deforestation models, socio-economic processes are often beyond the scope of these models. Such a low level of interest in the socio-economic dimension of deforestation limits the relevancy of these models for decision-making and may be the cause of their failure to accurately predict observed deforestation trends in the medium term. This study aims to propose a flexible methodology for taking into account multiple drivers of deforestation in tropical forested areas, where the intensity of deforestation is explicitly predicted based on socio-economic variables. By coupling a model of deforestation location based on spatial environmental variables with several sub-models of deforestation intensity based on socio-economic variables, we were able to create a map of predicted deforestation over the period 2001-2014 in French Guiana. This map was compared to a reference map for accuracy assessment, not only at the pixel scale but also over cells ranging from 1 to approximately 600 sq. km. Highly significant relationships were explicitly established between deforestation intensity and several socio-economic variables: population growth, the amount of agricultural subsidies, gold and wood production. Such a precise characterization of socio-economic processes allows to avoid overestimation biases in high deforestation areas, suggesting a better integration of socio-economic processes in the models. Whilst considering deforestation as a purely geographical process contributes to the creation of conservative models unable to effectively assess changes in the socio-economic and political contexts influencing deforestation trends, this explicit characterization of the socio-economic dimension of deforestation is critical for the creation of deforestation scenarios in REDD+ projects.

    Background Socio-economic inequalities may have an impact on the uptake of selfpaid vaccines. The aim of the study was to identify the effect of some socio economic determinants on vaccination rates with self-paid human papilloma virus (HPV) and rotavirus (RV) vaccines. Methods Vaccination coverage data, available in electronic database cepljenje.net (administered by the National Institute of Public Health), were collected at administrative unit level. The socio-economic determinants (the average gross pay in euros, the unemployment rate, the educational and households structure, the population density, the number of inhabitants, the number of children aged from 0 to 4, the number of women aged from 15 to 30) were extracted from Statistical Office of the Republic of Slovenia web page. The strength of the correlation between socioeconomic variables and self-paid HPV and RV vaccination rates was determined. Results Rotavirus vaccination rates show a slight negative correlation with the number of residents per administrative unit (ρ=−0.29, p=0.04), and no correlation with other socio-economic variables. Likewise, no correlation has been found between HPV vaccination rates and the selected socio-economic variables. Conclusion Ecological study did not reveal any correlations between socio economic variables and vaccination rates with RV and HPV self-paid vaccines on administrative unit level. PMID:27647088

    Background Individual and area socio-economic status (SES) are significant predictors of morbidity and mortality in developed and developing countries. However, the span in health from poorest to richest, that is, the socio-economic gradient, appears steeper for men than women. Objective Our aim is to understand women's apparent immunity to the health harms of the SES gradient. Design Findings from a non-systematic search of Medline for population-based, SES gradient studies reporting results for both men and women and with health outcomes of morbidity, mortality or self-rated health (SRH) were reflectively analyzed. Results The 36 papers reviewed generally showed women to be relatively immune to the SES gradient for all but cardiovascular health outcomes. However, addressing the interconnected nature of socio-economic circumstances, exploring whether some measures of SES had ambiguous meanings for either women or men, including modifiers of SES such as household circumstances, social capital or area gender equity, or using indicators of area SES that were contextual rather than aggregates of individual, compositional measures increased the SES gradient for women. Outcome measures that combined mental and physical health, accounted for gender differences in SRH and adjusted for sex-specific differences in causes of mortality also explained some of the observed amelioration of the SES gradient among women. Conclusions Socio-economic circumstances have a real and sustained impact on individual health. The SES gradient appears stronger for men than for women for all health outcomes other than heart disease. However, some of the observed variability between men and women may be an artifact of biased methodology. Considering webs of causation rather than individual markers of SES along with other sources of gender bias can explain much of women's blunted socio-economic gradient and deepen understanding of the pathways from SES to morbidity and mortality overall.

    Previous research shows that, compared to children without ADHD, children with ADHD have worse socio-emotional outcomes and more experience of socio-economic disadvantage. In this study, we explored if and how the increased emotional and behavioural difficulties faced by children with ADHD may be accounted for by their more disadvantaged socio-economic circumstances. Our study, using data from 180 children (149 boys) with ADHD from the Millennium Cohort Study, had two aims. First, to examine the role of socio-economic disadvantage in the trajectories of emotional and conduct problems in children with ADHD at ages 3, 5, 7 and 11 years. Second, to explore the roles of the home environment (household chaos) and parenting (quality of emotional support, quality of the parent-child relationship and harsh parental discipline) in mediating any associations between socio-economic disadvantage and child emotional and conduct problems. Using growth curve models, we found that socio-economic disadvantage was associated with emotional and conduct problems but neither the home environment nor parenting attenuated this association. Lower quality of the parent-child relationship and harsher discipline were associated with more conduct problems. It appears that socio-economic disadvantage and parenting contribute independently to the prediction of comorbid psychopathology in children with ADHD.

    The aim of the study was to describe the associations between socio-economic status and type 2 diabetes in a non-institutionalised population aged 70 years or over. Diabetes was assessed on the basis of self-reports and additionally 2-h oral glucose tolerance test for the subjects on diet treatment. Socio-economic status was assessed by questions on marital status, number of residents in household, basic education, self-rated income and economic status. In the population of 379 subjects (141 men), 14% (n = 19) of men and 19% (n = 46) of women had known diabetes. Known diabetes was less common among married compared to unmarried, widowed or divorced subjects. Diabetes was also more common among men with higher compared to lower level of basic education, while a reverse trend was seen among women. Women, who had been engaged in manual labour, had diabetes more often compared to those engaged in administrative work. Diabetes was more common among men who rated their income as good, but the opposite was true of women. Higher income among men and lower income among women were the most powerful variables associated with known diabetes. Known diabetes was more common in elderly women with lower socio-economic status, whereas the opposite was true of men. This finding suggests that the impact of the socio-economic changes that have taken place in Finland in the 20th century on the risk factors for diabetes has been greater among men with higher and women with lower socio-economic status.

    Objective: To analyze the association between influenza and pneumococcus vaccination and blood cholesterol and blood sugar measurement by Belgian elderly respondents (≥65 years) and socio-demographic characteristics, risk factors, health status and socio-economic status (SES). Methods: A cross-sectional study based on 4,544 non-institutionalized elderly participants of the Belgian Health Interview Surveys 2004 and 2008. Multivariate logistic regression models were constructed to examine the independent effect of socio-demographic characteristics, risk factors, health status and SES on the four preventive services. Results: After adjustment for age, sex, region, survey year, living situation, risk factors (body mass index, smoking status, physical activity) and health status (self-assessed health and longstanding illness) lower educated elderly were significantly less likely to report a blood cholesterol and blood sugar measurement. For instance, elderly participants with no degree or only primary education were less likely to have had a cholesterol and blood sugar measurement compared with those with higher education. Pneumococcus vaccination was not related to educational level, but lower income groups were more likely to have had a pneumococcus immunization. Influenza vaccination was not significantly related to SES. Conclusion: The results highlight the need to promote cholesterol and blood sugar measurement for lower SE groups, and pneumococcus immunization for the entire elderly population. Influenza immunization seems to be equally spread among different SE groups. PMID:24368427

    Background: Informal/unorganised sector covers 92% of the total work force in India. About 50% of the construction industrial workers belonged to informal/unorganised sector. Material and Methods: The present study was undertaken to know the socio-economic status of construction worker and availing of the social security measures by this working group. Results and Conclusion: The study covered 150 subjects with an average age of 32 years and mean duration of work was nine years. They were poorly paid with an average income of Rs. 4956/-per month. Though the literacy rate was high (79%) yet most of them were addicted to different habits like drinking alcohol, smoking bidi, tobacco chewing etc., Abusing the family members were noted in (30%) of the cases. Their regular intake of food, usually inadequate in quantity and was mainly consisted of rice, pulses, vegetables. Though most of the subjects (73%) were living in kacha houses yet the latrine facilities were available to 62% of total covered houses. Majority of them were unaware of the different social security schemes/measures. The details have been discussed here. PMID:23580836

    Socio-economic differences in diet are a potential contributor to health inequalities. The present study provides an up-to-date picture of socio-economic differences in diet in the UK, focusing on the consumption of three food groups and two nutrients of public health concern: fruit and vegetables; red and processed meat; oily fish; saturated fats; non-milk extrinsic sugars (NMES). We analysed data for 1491 adults (age ≥ 19 years) from the National Diet and Nutrition Survey 2008-2011. Socio-economic indicators were household income, occupational social class and highest educational qualification. Covariate-adjusted estimates for intakes of fruit and vegetables, red and processed meat, and both nutrients were estimated using general linear models. Covariate-adjusted OR for oily fish consumption were derived with logistic regression models. We observed consistent socio-economic gradients in the consumption of the three food groups as estimated by all the three indicators. Contrasting highest and lowest levels of each socio-economic indicator, we observed significant differences in intakes for the three food groups and NMES. Depending on the socio-economic indicator, highest socio-economic groups consumed up to 128 g/d more fruit and vegetables, 26 g/d less red and processed meat, and 2·6% points less NMES (P< 0·05 for all). Relative to lowest socio-economic groups, highest socio-economic groups were 2·4 to 4·0 times more likely to eat oily fish. No significant patterns in saturated fat consumption were apparent. In conclusion, socio-economic differences were identified in the consumption of food groups and one nutrient of public health importance. Aligning dietary intakes with public health guidance may require interventions specifically designed to reduce health inequalities.

    Background A relatively consistent body of literature, mainly from high-income countries, supports an inverse association between socio-economic status (SES) and risk of cardiovascular disease (CVD). Data from low- and middle-income countries are scarce. This study explores SES differences in cardiovascular health (CVH) in the Republic of Srpska (RS), Bosnia and Herzegovina, a middle-income country. Methods We collected information on SES (education, employment status and household’s relative economic status, i.e. household wealth) and the 7 ideal CVH components (smoking status, body mass index, physical activity, diet, blood pressure, total cholesterol, and fasting blood glucose) among 3601 participants 25 years of age and older, from the 2010 National Health Survey in the RS. Based on the sum of all 7 CVH components an overall CVH score (CVHS) was calculated ranging from 0 (all CVH components at poor levels) to 14 (all CVH components at ideal levels). To assess the differences between groups the chi-square test, t-test and ANOVA were used where appropriate. The association between SES and CVHS was analysed with multivariate linear regression analyses. The dependent variable was CVHS, while independent variables were educational level, employment status and wealth index. Results According to multiple linear regression analysis CVHS was independently associated with education attainment and employment status. Participants with higher educational attainment and those economically active had higher CVHS (b = 0.57; CI = 0.29–0.85 and b = 0.27; CI = 0.10–0.44 respectively) after adjustment for sex, age group, type of settlement, and marital status. We failed to find any statistically significant difference between the wealth index and CVHS. Conclusion This study presents the novel information, since CVHS generated from the individual CVH components was not compared by socio-economic status till now. Our finding that the higher overall CVHS was independently

    This research examines the Health Promotion Behavior (HPB) models regarding elderly pedestrians' behaviors and attitudes. We studied cognitive-psychological variables, such as risk estimation, self-efficacy and demographic variables and compared elderly pedestrians' attitudes and behaviors in a city with higher socio-economic level (Tel Aviv) versus a city with low socio-economic level (Beer Sheva). We expected to find more problematic behaviors among elderly pedestrians in the low socio-economic city compared to the high socio-economic city, and also less feeling of self-efficacy, and lessened awareness of the risks, that leads to lessened willingness to adopt preventive behaviors. The research was conducted in two studies. The first study was based on observations on 2591 pedestrians in six similar crosswalks in both cities. It revealed that pedestrians in the high socio-economic city demonstrated safer road crossing patterns than in the low socio-economic city and that elderly pedestrians reveal safer crossing patterns than younger pedestrians. We found an interaction of location and age due to greater gap of safe behaviors of elderly and young pedestrians in the high socio-economic city than in the low socio-economic city. In Tel Aviv elderly adhere to the crossing rules much more than the young while in Beer Sheva elderly and young people are almost similar in their crossing patterns. The second study used questionnaires that have been completed by 143 elderly in both cities. The questionnaires referred to (a) demographic variables such as gender, age, marital status, education, socio-economic level, (b) variables related to the affiliation to the main culture such as migration, date of migration, knowledge in Hebrew (local language) and connectivity to media and (c) cognitive as well as psychological variables related to the decline to adopt healthy behaviors based on Schwarzer and Fuchs (1995). This part also indicated that elderly in Tel Aviv have higher

    Background Malnutrition in children under five years remains a significant problem in Bangladesh, despite substantial socio-economic progress and a decade of interventions aimed at improving it. Although several studies have been conducted to identify the important risk factors of malnutrition, none of them assess the role of low birth weight (LBW) despite its high prevalence (36%). This study examines the association between LBW and malnutrition using data from the Bangladesh Demographic and Health Survey (BDHS) 2011 and provides practical guidelines for improving nutritional status of children. Methods Malnutrition in children is measured in terms of their height-for-age, weight-for-height, and weight-for-age. Children whose Z-scores for either of these indices are below two standard deviations (–2SD) from median of WHO’s reference population are considered as stunted, wasted or underweight, respectively. The association between malnutrition and LBW was investigated by calculating adjusted risk-ratio (RR), which controls for potential confounders such as child’s age and sex, mother’s education and height, length of preceding-birth-interval, access to food, area of residence, household socio-economic status. Adjusted RR was calculated using both Cochran-Mantel-Haenszel approach and multivariable logistic regression models controlling for confounder. Results The prevalence of malnutrition was markedly higher in children with LBW than those with normal birth-weights (stunting: 51% vs 39%; wasting: 25% vs 14% and underweight: 52% vs 33%). While controlling for the known risk factors, children with LBW had significantly increased risk of becoming malnourished compared to their counter part with RR 1.23 (95% CI:1.16–1.30), 1.71 (95% CI:1.53–1.92) and 1.47 (95% CI: 1.38–1.56) for stunting, wasting and underweight, respectively. The observed associations were not modified by factors known to reduce the prevalence of malnutrition, such as higher education of

    2012-01-01

    Cultural traditions at the end of life solidify societal members. As the world becomes more globalized, socio-economic factors affect how traditional practices are expressed, and the role and toll they make on modern societies. This article examines the contemporary Akan funeral practices in Ghana. Akan lineage members, from birth through puberty, marriage, maturity, old age, go through various rites of passage that bond them culturally and spiritually to others in society. One such ritual is funeral celebration. Funeral celebration, an old practice, has always been at the heart of public social events of Akan people. However, the changes in Ghanaian Akan funerals over the past 4 decades, and their impact on the people, make this an important topic. The article describes the Akan belief of life after death, the respect accorded to the dead, the prestige associated with successful funeral celebrations, and socio-economic factors that continue to shape Akan funeral practices. Socio-economic impact and the resulting challenges are discussed.

    Background. Patterns of risk behaviour during teenage years may vary by socio-economic status (SES). We aimed to examine possible associations between individual and multiple risk behaviours and three measures of SES in mid-adolescence. Methods. The sample (n = 6406) comprised participants from the Avon Longitudinal Study of Parents and Children, a UK birth cohort. Thirteen risk behaviours spanning sexual health, substance use, self-harm, vehicle-related injury, criminality and physical inactivity were assessed in mid-adolescence (age 15–16 years). Associations between three measures of SES (maternal education, household income and parental social class) and (i) individual risk behaviours and (ii) the total number of risk behaviours were examined. Results. For a one-category reduction in social class, maternal education or income, the odds of having a greater number of multiple risk behaviours increased by 22, 15 and 12%, respectively. At the individual level, there was evidence of a strong relationship with decreasing SES across all three measures of SES and criminality, car passenger risk, TV viewing, scooter risk, early sexual behaviour and weekly tobacco use but insufficient evidence of a relationship for physical inactivity, cycling without a helmet and illicit substance use. There was weak evidence of association between SES and hazardous drinking, self-harm, cannabis use and unprotected sex, but this was not consistent across the SES measures. Conclusion. The association between multiple risk behaviours and SES suggests that prevention strategies should apply the principal of proportionate universalism with a focus on more deprived populations, within a population-wide strategy, to prevent widening of social inequalities.

    Ocean acidification is increasingly recognized as a component of global change that could have a wide range of impacts on marine organisms, the ecosystems they live in, and the goods and services they provide humankind. Assessment of these potential socio-economic impacts requires integrated efforts between biologists, chemists, oceanographers, economists and social scientists. But because ocean acidification is a new research area, significant knowledge gaps are preventing economists from estimating its welfare impacts. For instance, economic data on the impact of ocean acidification on significant markets such as fisheries, aquaculture and tourism are very limited (if not non-existent), and non-market valuation studies on this topic are not yet available. Our paper summarizes the current understanding of future OA impacts and sets out what further information is required for economists to assess socio-economic impacts of ocean acidification. Our aim is to provide clear directions for multidisciplinary collaborative research.

    Addressing social determinants in the field of tuberculosis (TB) has received great attention in the past years, mainly due to the fact that worldwide TB incidence has not declined as much as expected, despite highly curative control strategies. One of the objectives of the World Health Organization Global Task Force on TB Impact Measurement is to assess the prevalence of TB disease in 22 high-burden countries by active screening of a random sample of the general population. These surveys provide a unique opportunity to assess socio-economic determinants in relation to prevalent TB and its risk factors. This article describes methods of measuring the socio-economic position in the context of a TB prevalence survey. An indirect measurement using an assets score is the most feasible way of doing this. Several examples are given from recently conducted prevalence surveys of the use of an assets score, its construction, and the analyses of the obtained data.

    This paper investigates the relationship between suicide rates and prevalence of mental disorder and suicide attempts, across socio-economic status (SES) groups based on area of residence. Australian suicide data (1996-1998) were analysed in conjunction with area-based prevalences of mental disorder derived from the National Survey of Mental Health and Well-Being (1997). Poisson regression models of suicide risk included age, quintile of area-based SES, urban-rural residence, and country of birth (COB), with males and females analysed separately. Analysis focussed on the association between suicide and prevalences of (ICD-10) affective disorders, anxiety disorders, substance use disorders and suicide attempts by SES group. Prevalences of other psychiatric symptomatology, substance use problems, health service utilisation, stressful life-events and personality were also investigated. Significant increasing gradients were evident from high to low SES groups for prevalences of affective disorders, anxiety disorders (females only), and substance use disorders (males only); sub-threshold drug and alcohol problems and depression; and suicide attempts and suicide (males only). Prevalences of mental disorder, other sub-threshold mental health items and suicide attempts were significantly associated with suicide, but in most cases associations were reduced in magnitude and became statistically non-significant after adjustment for COB, urban-rural residence, and SES. For male suicide the relative risk (RR) in the lowest SES group compared to the highest was 1.40 (95% CI 1.29-1.52, p<0.001) for all ages, and 1.46 (95% CI 1.27-1.67, p<0.001) for male youth (20-34 years). This relationship was not substantially modified in males when regression models included prevalences of affective disorders, and other selected mental health variables and demographic factors. From a population perspective, SES remained significantly associated with suicide after controlling for the

    International case studies of protected area performance increasingly report that conservation and socio-economic outcomes are interdependent. Effective conservation requires support and cooperation from local governments and communities, which in turn requires that protected areas contribute to the economic well-being of the communities in which they are sited. Despite increasing recognition of their importance, robust studies that document the socio-economic impacts of protected areas are rare, especially in the developed world context. We proposed 3 potential pathways through which protected areas might benefit local communities in the developed world: the improved local housing value, local business stimulus, and increased local funding pathways. We examined these pathways by undertaking a statistical longitudinal analysis of 110 regional and rural communities covering an area of approximately 600,000 km(2) in southeastern Australia. We compared trends in 10 socio-economic indicators describing employment, income, housing, business development and local government revenue from 2000 to 2010. New protected areas acquisitions led to an increased number of new dwelling approvals and associated developer contributions, increased local business numbers, and increased local government revenue from user-pays services and grants. Longer-term effects of established protected areas included increased local council revenue from a variety of sources. Our findings provide support for each of our 3 proposed benefit pathways and contribute new insights into the cycling of benefits from protected areas through the economy over time. The business and legislative models in our study are typical of those operating in many other developed countries; thus, the benefit pathways reported in our study are likely to be generalizable. By identifying and communicating socio-economic benefits from terrestrial protected areas in a developed world context, our findings represent an important

    Socio-economic inequality is characterized from data using various indices. The Gini (g) index, giving the overall inequality is the most common one, while the recently introduced Kolkata (k) index gives a measure of 1 - k fraction of population who possess top k fraction of wealth in the society. Here, we show the relationship between the two indices, using both empirical data and analytical estimates. The significance of their relationship has been discussed.

We find variations in the prevalence and timing of widowhood across the study countries, and associations between widowhood and being in the poorest wealth quintile for all five countries. For other deprivations, national experiences varied, with stronger and more consistent effects for India and China. These findings challenge generalised claims about widowhood and call for more contextualised analysis. PMID:27594712

    Pediculosis is a common infestation in schoolchildren but little is known about the factors influencing its prevalence. The aim of this study was to determine the prevalence of head lice in schoolchildren in Ghent and to investigate the independent association between individual characteristics of the child, socio-economic status (SES) of the family and head lice. The prevalence of head lice at baseline and 14 days after treatment advice was determined by the wet combing method in a total of 6,169 schoolchildren age 2.5 to 12 years from Ghent (Belgium). Age, sex, educational level and hair characteristics of the child, SES of the family, and number of children in the family was collected by the school health department. The prevalence of head lice was 8.9%. The only statistically significant factors at the child level are SES, the number of children in the family, hair length and hair colour. Treatment failure was recorded in 41% of the children positive at baseline screening and was significantly related to hair colour and SES. This study demonstrated that the prevalence of head lice is determined by clustering of children rather than by characteristics of the child. The management of head lice should take a community-based approach equally involving families, schools, health care professionals and the government.

    Purpose To estimate the prevalence and causes of blindness and visual impairment in Cape Town, South Africa and to explore socio-economic and demographic predictors of vision loss in this setting. Methods A cross sectional population-based survey was conducted in Cape Town. Eighty-two clusters were selected using probability proportionate to size sampling. Within each cluster 35 or 40 people aged 50 years and above were selected using compact segment sampling. Visual acuity of participants was assessed and eyes with a visual acuity less than 6/18 were examined by an ophthalmologist to determine the cause of vision loss. Demographic data (age, gender and education) were collected and a socio-economic status (SES) index was created using principal components analysis. Results Out of 3100 eligible people, 2750 (89%) were examined. The sample prevalence of bilateral blindness (presenting visual acuity <3/60) was 1.4% (95% CI 0.9–1.8). Posterior segment diseases accounted for 65% of blindness and cataract was responsible for 27%. The prevalence of vision loss was highest among people over 80 years (odds ratio (OR) 6.9 95% CI 4.6–10.6), those in the poorest SES group (OR 3.9 95% CI 2.2–6.7) and people with no formal education (OR 5.4 95% CI 1.7–16.6). Cataract surgical coverage was 68% in the poorest SES tertile (68%) compared to 93% in the medium and 100% in the highest tertile. Conclusions The prevalence of blindness among people ≥50 years in Cape Town was lower than expected and the contribution of posterior segment diseases higher than previously reported in South Africa and Sub Saharan Africa. There were clear socio-economic disparities in prevalence of vision loss and cataract surgical coverage in this setting which need to be addressed in blindness prevention programs. PMID:22363476

    In this paper, we present different applications of finite state mean field games to socio-economic sciences. Examples include paradigm shifts in the scientific community or consumer choice behaviour in the free market. The corresponding finite state mean field game models are hyperbolic systems of partial differential equations, for which we present and validate different numerical methods. We illustrate the behaviour of solutions with various numerical experiments, which show interesting phenomena such as shock formation. Hence, we conclude with an investigation of the shock structure in the case of two-state problems.

    The study assessed inequalities in mortality of Lithuanian urban and rural populations throughout the period of socio-economic transition (1990-2000). Mortality from major causes of death, except cancers in females, was higher among the rural population. Inequality in mortality increased during the period of transition, especially among males, mainly due to more rapidly improving health of the urban population. Cardiovascular diseases and external causes made the largest contribution to the inequality. Differences in mortality of urban and rural populations point to greater social and psychological stress affecting the rural population, unhealthy life styles, inequities in accessibility of health care and lack of preventive programs in rural areas.

    Although new technologies and treatments have improved the quality of life of people with haemophilia, they still face many health and socio-economic problems. We designed this study to identify some of these problems according to patients' attitudes towards efforts to solve them. This cross-sectional study was conducted in Shiraz, southern Iran, during January and May 2010. The participants were 100 patients with haemophilia who were referred to Shiraz Hemophilia Center, a major referral centre in southern Iran. A questionnaire was used to obtain data on the attitudes of haemophilic patients about some of their health and socio-economic problems. Mean age of the patients was 28.2 ± 9.0 (range of 16-67 years). In univariate analysis, disease severity, joint involvement, HCV status, income level and educational level of the patients were found to have possible effect on patients' attitude towards their health and socio-economic problems. However, in multivariate model we found that only income level, educational level and HCV status as independent factors influencing the patients' attitude towards childbearing, employment problems, occupational problems, social and friend relationship and continuing education. Haemophilic patients had many social and health problems, which could be alleviated with interdisciplinary interventions to improve their quality of life. Financial support of these patients should be taken into account to reduce their economic problems. Also, encouraging them and providing facilities to achieve a higher educational level could help them to have a better attitude towards their health and overcome the disease-related problems.

    International and interethnic differences in prostate cancer incidence suggest an environmental aetiology, and lifestyle and socio-economic factors have been studied, but with divergent results. Information on a cohort of 22 895 Norwegian men aged 40 years and more was obtained from a health examination and two self-administered questionnaires. Information on incident cases of prostate cancer was made available from the Cancer Registry. We used the Cox proportional hazards model to calculate incidence rate ratios as estimates of the relative risk (RR) with 95% confidence interval (CI). Reported P -values are two-sided. During a mean follow-up of 9.3 years, 644 cases were diagnosed. Risk was elevated among men in occupations of high compared to low socio-economic status (RR = 1.30; 95% CI 1.05–1.61), and among men with high education compared to the least educated (RR = 1.56; 95% CI 1.11–2.19). A RR of 1.56 (95% CI 0.97–2.44) suggests a higher risk among divorced or separated men, compared with married men. We also found indications of a weak negative association with leisure-time physical activity (RR = 0.80; 95% CI 0.62–1.03 for high vs low activity), a weak positive association with increasing number of cigarettes (P = 0.046), while alcohol consumption was not related to the risk of prostate cancer. These results show that high socio-economic status is associated with increased risk of prostate cancer, and that divorced or separated men might be at higher risk than married men. Data from this study also indicate that high levels of physical activity may reduce prostate cancer risk. © 2000 Cancer Research Campaign PMID:10755415

    Because of the global nature of climate change, any assessment of the effects of plans, policies, and response to climate change demands a model that encompasses the entire Earth System, including socio- economic factors. Physics-based climate models of the factors that drive global temperatures, rainfall patterns, and sea level are necessary but not sufficient to guide decision making. Actions taken by farmers, industrialists, environmentalists, politicians, and other policy makers may result in large changes to economic factors, international relations, food production, disease vectors, and beyond. These consequences will not be felt uniformly around the globe or even across a given region. Policy models must comprehend all of these considerations. Combining physics-based models of the Earth's climate and biosphere with societal models of population dynamics, economics, and politics is a grand challenge with high stakes. We propose to leverage our recent advances in modeling and simulation of military stability and reconstruction operations to models that address all these areas of concern. Following over twenty years' experience of successful combat simulation, JPL has started developing Minerva, which will add demographic, economic, political, and media/information models to capabilities that already exist. With these new models, for which we have design concepts, it will be possible to address a very wide range of potential national and international problems that were previously inaccessible. Our climate change model builds on Minerva and expands the geographical horizon from playboxes containing regions and neighborhoods to the entire globe. This system consists of a collection of interacting simulation models that specialize in different aspects of the global situation. They will each contribute to and draw from a pool of shared data. The basic models are: the physical model; the demographic model; the political model; the economic model; and the media

    The socio-economic aspects of areca nut consumption have been overlooked. A narrative review was conducted to establish some of these features of areca nut consumption. Medline, Pubmed and the World Wide Web were searched using the terms: areca nut, betel nut, areca catechu and pan masala. Further analysis was conducted of datasets describing aspects of United Kingdom areca nut sales and consumption. South Asian economies at different stages of development have varying areca nut cultivation practices, employment opportunities and marketing strategies. Attempts at regulation of areca nut import and sales are described. Retail practice among the South Asian communities of the United Kingdom was found to reflect the diverse consumer practices current in their countries of origin. A study of areca nut consumption patterns and motivations among Bangladeshi women resident in East London identified differences between those chewing areca nut in paan with and without tobacco. Further research into the socio-economic aspects of areca nut consumption is needed which should be multidisciplinary in focus, of sound scientific quality and incorporating the opinions of consumers.

    Objective: To determine the coverage of childhood immunization appropriate for age among socio-economically disadvantaged recent migrants living in East China and to identify the determinants of full immunization uptake among these migrant children. Methods: This is a cross-sectional survey of 1,426 migrant mothers with a child aged ≤24 months, who were interviewed with a pretested questionnaire. Various vaccines, migration history and some other social-demographic and income details were collected. Single-level logistic regression analyses were applied to identify the determinants of full immunization status. Results: Immunization coverage rates are lower among migrants and even lower among recent migrants. The likelihood of a child receiving full immunization rise with parents’ educational level and the frequency of mother’s utilization of health care. Higher household income also significantly increase the likelihood of full immunization, as dose post-natal visits by a health worker. Conclusions: Recent migrant status favours low immunization uptake, particularly in the vulnerability context of alienation and livelihood insecurity. Services must be delivered with a focus on recent migrants. Investments are needed in education, socio-economic development and secure livelihoods to improve and sustain equitable health care services. PMID:23839061

    Social scientists generally agree that better individual economic prospects enhance the probability of marriage for men, whereas there are conflicting views with regard to women. Moreover, it is argued that cohabitation does not require as strong an economic foundation as marriage. The aim of this study, which was based on Finnish register data, was to find out how the socio-economic resources of young adults affect first-union formation, and whether the effects vary by sex or union type. The results show that high education, labour-force participation, and high income seem to promote union formation. The findings are similar for women and men, which is plausible given the comparatively gender-egalitarian societal context. Similar factors encourage entry into both union types, although the union-promoting effects of university-level education and stable employment are stronger in the marriage models, suggesting that long-term prospects are more important when marriage is contemplated.

    The demographic and socio-economic determinants of post-neonatal deaths (n = 475) in a special project area of rural northern India (Ballabgarh) were ascertained from 1991 to 1999 using the electronic database system of the project area for data extraction, and were compared with the eligible living children of the same age using a matched population-based case-control study design. Similar determinants were also ascertained in neonatal deaths (n = 212) using the same study design. After controlling for the potential confounders using conditional logistic regression analyses, lower caste (a proxy measure for low socio-economic conditions in rural India) was found to be significantly associated with higher post-neonatal deaths (OR = 2.21). Higher maternal age (>30 years) and fathers' lower educational levels were significantly associated with higher neonatal deaths, in addition to higher post-neonatal deaths in the same area.

    Low socio-economic status (SES) has been associated with lower cervical screening rates. Mass media is one known strategy that can increase cervical screening participation. This study sought to determine whether a mass media campaign conducted in Victoria, Australia, in 2005 was effective in encouraging women across all SES groups to screen. Data were obtained from the Victorian Cervical Cytology Registry for each Pap test registered during 2005 and categorized into SES quintiles using the Index of Socio-Economic Advantage/Disadvantage. Negative binomial regression was used to determine the impact of the campaign on the weekly number of Pap tests and whether the media campaign had a differential effect by SES, after adjusting for the number of workdays per week, age group and time since previous test. Cervical screening increased 27% during the campaign period and was equally effective in encouraging screening across all SES groups, including low-SES women. Mass media campaigns can prompt increased rates of cervical screening among all women, not just those from more advantaged areas. Combining media with additional strategies targeted at low-SES women may help lessen the underlying differences in screening rates across SES.

    Can traces of rapid socio-economic changes within a society be reflected in experimental games? The post-Mao reforms in China provide a unique natural quasi-experiment to study people from the same society who were raised with radically different values about distribution of wealth and altruistic behavior. We tested whether the size of offers in the ultimatum and dictator games are an increasing function of the number of years Chinese citizens experienced of the Mao era ("planned economy"). For the cohort that lived throughout the entire Mao era, we found that mean offers in the two games were substantially higher than what is typically offered in laboratory studies. These offers were also higher than those of two younger Chinese cohorts. In general, the amount offered decreased with less time spent under Mao, while in the oldest group in which every member spent the same amount of time under Mao, the younger members tended to offer more, suggesting an additional effect of early education under Mao and contradicting the alternative hypothesis that generosity increases with age. These results suggest that some of the observed individual differences in the offers made in experimental games can be traced back to the values of the socio-economic era in which individuals grew up.

    While sex and socio-economic disparities in physical activity have been well documented, not all disadvantaged women are inactive. This study aimed to examine correlates of achieving recommended levels of physical activity among women of low socio-economic position. In 2005, a population-based sample of 291 women with low educational attainment provided survey data on leisure time physical activity (LTPA). Participants reported potential personal (enjoyment and self-efficacy; barriers; intentions; guilt and priorities; routines and scheduling; occupational physical activity; television viewing), social (support from family/friends; social participation; sport/recreation club membership; dog ownership) and environmental (aesthetics; safety; local access; footpaths; interesting walks; busy roads to cross; heavy traffic) correlates of physical activity. Nearly 40% of participants achieved recommended LTPA (150 min week(-1)). Multivariable analyses revealed that higher levels of self-efficacy for walking [prevalence ratio (PR) 2.05, 95% confidence interval (CI) 1.19-3.53], higher enjoyment of walking (PR 1.48, 95% CI 1.04-2.12), greater intentions to be active (PR 1.97, 95% CI 1.12-3.45) and having set routines for physical activity (PR 1.91, 95% CI 1.18-3.09) were significantly associated with achieving recommended LTPA. Personal factors were the characteristics most strongly associated with achieving recommended levels of LTPA among women from socio-economically disadvantaged backgrounds.

    Background Human immunodeficiency virus (HIV) is a significant contributor to Malawi's burden of disease. Despite a number of studies describing socio-economic differences in HIV prevalence, there is a paucity of evidence on socio-economic inequity in HIV testing in Malawi. Objective To assess horizontal inequity (HI) in HIV testing in Malawi. Design Data from the Demographic and Health Surveys (DHSs) 2004 and 2010 in Malawi are used for the analysis. The sample size for DHS 2004 was 14,571 (women =11,362 and men=3,209), and for DHS 2010 it was 29,830 (women=22,716 and men=7,114). The concentration index is used to quantify the amount of socio-economic-related inequality in HIV testing. The inequality is a primary method in this study. Corrected need, a further adjustment of the standard decomposition index, was calculated. Standard HI was compared with corrected need-adjusted inequity. Variables used to measure health need include symptoms of sexually transmitted infections. Non-need variables include wealth, education, literacy and marital status. Results Between 2004 and 2010, the proportion of the population ever tested for HIV increased from 15 to 75% among women and from 16 to 54% among men. The need for HIV testing among men was concentrated among the relatively wealthy in 2004, but the need was more equitably distributed in 2010. Standard HI was 0.152 in 2004 and 0.008 in 2010 among women, and 0.186 in 2004 and 0.04 in 2010 among men. Rural–urban inequity also fell in this period, but HIV testing remained pro-rich among rural men (HI 0.041). The main social contributors to inequity in HIV testing were wealth in 2004 and education in 2010. Conclusions Inequity in HIV testing in Malawi decreased between 2004 and 2010. This may be due to the increased support to HIV testing by global donors over this period. PMID:27790970

    Material deprivation is an important determinant of health inequalities in adults but there remains debate about the extent of its importance for adolescent wellbeing. Research has found limited evidence for an association between adolescent health and socio-economic status, leading authors to suggest that there is an 'equalisation' of health across socio-economic groups during the adolescent stage of the life-course. This paper explores this 'equalisation' hypothesis for adolescent psychological wellbeing from a geographical perspective by investigating associations between neighbourhood deprivation and self-esteem in Britain and Canada. Data from the British Youth Panel (BYP) and the National Longitudinal Survey of Children and Youth (NLSCY) on adolescents aged 11-15 for the time period 1994-2004 were used to estimate variations in low self-esteem between neighbourhoods using multilevel logistic regression. Models were extended to estimate associations between self-esteem and neighbourhood deprivation before and after adjustment for individual and family level covariates. Moderation by age, sex, urban/rural status, household income and family structure was investigated. There were no significant differences in self-esteem between the most deprived and most affluent neighbourhoods (Canada unadjusted OR = 1.00, 95% CI 0.76, 1.33; Britain unadjusted OR = 1.25, 95% CI 0.74, 2.13). The prevalence of low self-esteem was higher (in Canada) for boys in the least deprived neighbourhoods compared to other neighbourhoods. No other interactions were observed. The results presented here offer some (limited) support for the socio-economic equalisation in youth hypothesis from a geographical perspective: with specific reference to equalisation of the relationship between neighbourhood deprivation and self-esteem and psychological health in early adolescence. This contrasts with previous research in the United States but supports related work from Britain. The lack of

    In South Africa, a country where almost half the population lives in poverty, we have built the multi-million dollar Southern African Large Telescope, we have begun on the even more expensive Karoo Array Telescope, and we are one of the two finalists bidding to host the multi-billion dollar Square Kilometre Array! In trying to communicate astronomy to the public, how do we justify such spending to a family in a rural area living in poverty? This presentation will expand on efforts in South Africa, specifically the SALT Collateral Benefits Programme, which are trying to answer these seemingly difficult questions. The socio-economic impact of astronomy on societies, especiallythose in the vicinity of these large telescope projects, will be investigated, with examples and experiences being shared, especially from the sparsely populated Northern Cape Province of South Africa.

    Global losses from floods are increasing, with renewed calls for action to reduce their impact. In each country, region or city, many actions can protect the population and help rebuild and recover: building dikes and restoring mangroves; land-use planning; early warning and evacuation; insurance and social safety nets. What should be the priorities? How to build a comprehensive strategy? Is progress being made? We propose a tool - a national-level scorecard based on welfare economics - to assess a country's socio-economic resilience to river floods and identify the most promising policy options in different contexts to reduce the impact of floods on well-being. The tool is applied to 90 countries using open databases, and can serve as a starting point for designing policies and more in-depth local studies.

    Among the numerous factors that influence the pattern of children's growth and development there are factors of the changeable socio-economic environment. The inequalities among the socio-economic strata in the Hungarian society have increased during last decades. The main objective of the study was to examine the body structure of children and adolescents living in different socio-economic backgrounds. The subjects of the present paper (9479 boys, 9304 girls) were examined in the 2nd Hungarian National Growth Study 2003-2006. Body structure was assessed by some absolute body dimensions, BMI, body composition and body shape indices. Children were grouped into relatively good, average and poor socio-economic subgroups by considering the education and occupation of the parents as well as the number of children in the family. Significant differences were found in the body structure of children varying in the socio-economic background: the better the socio-economic conditions the higher stature in both genders, while the lower relative fatness was found only in pubertal girls. The prevalence of unhealthy nutritional statuses (both underweight and overweight/ obese) was significantly lower in children living in better socio-economic conditions in both genders. Differences that were found in the body structure of children living in different socio-economic backgrounds emphasize the importance of using reference growth values layered also to socio-economic strata for screening nutritional status in childhood and adolescence.

    Background Interventions to prevent rape perpetration must be designed to address its drivers. This paper seeks to extend understanding of drivers of single and multiple perpetrator rape (referred to here as SPR and MPR respectively) and the relationships between socio-economic status, childhood trauma, peer pressure, other masculine behaviours and rape. Method 1370 young men aged 15 to 26 were interviewed as part of the randomised controlled trial evaluation of Stepping Stones in the rural Eastern Cape. We used multinomial to compare the characteristics of men who reported rape perpetration at baseline. We used structural equation modelling (SEM) to examine pathways to rape perpetration. Results 76.1% of young men had never raped, 10.0% had perpetrated SPR and 13.9% MPR. The factors associated with both MPR and SPR (compared to never having raped) were indicators of socio-economic status (SES), childhood trauma, sexual coercion by a woman, drug and alcohol use, peer pressure susceptibility, having had transactional sex, multiple sexual partners and being physically violent towards a partner. The SEM showed the relationship between SES and rape perpetration to be mediated by gender inequitable masculinity. It was complex as there was a direct path indicating that SES correlated with the masculinity variable directly such that men of higher SES had more gender inequitable masculinities, and indirect path mediated by peer pressure resistance indicated that the former pertained so long as men lacked peer pressure resistance. Having a higher SES conveyed greater resistance for some men. There was also a path mediated through childhood trauma, such that men of lower SES were more likely to have a higher childhood trauma exposure and this correlated with a higher likelihood of having the gender inequitable masculinity (with or without the mediating effect of peer pressure resistance). Discussion Both higher and lower socio-economic status were associated with raping

    PubMed Central

    2011-01-01

    Background Despite free healthcare to pregnant women and children under the age of six, access to healthcare has failed to secure better child health outcomes amongst all children of the country. There is growing evidence of socioeconomic gradient on child health outcomes Methods The objectives of this study were to measure inequalities in child mortality, HIV transmission and vaccination coverage within a cohort of infants in South Africa. We also used the decomposition technique to identify the factors that contribute to the inequalities in these three child health outcomes. We used data from a prospective cohort study of mother-child pairs in three sites in South African. A relative index of household socio-economic status was developed using principal component analysis. This paper uses the concentration index to summarise inequalities in child mortality, HIV transmission and vaccination coverage. Results We observed disparities in the availability of infrastructure between least poor and most poor families, and inequalities in all measured child health outcomes. Overall, 75 (8.5%) infants died between birth and 36 weeks. Infant mortality and HIV transmission was higher among the poorest families within the sample. Immunisation coverage was higher among the least poor. The inequalities were mainly due to the area of residence and socio-economic position. Conclusion This study provides evidence that socio-economic inequalities are highly prevalent within the relatively poor black population. Poor socio-economic position exposes infants to ill health. In addition, the use of immunisation services was lower in the poor households. These inequalities need to be explicitly addressed in future programme planning to improve child health for all South Africans. PMID:21463530

    ABSTRACT Objective: To identify the sociodemographic, socio-economic, clinical and behavioural factors that modify the experience of decayed, missing and filled teeth (DMFT) and caries prevalence in Nicaraguan children 9-12 years old. Subjects and Methods: We conducted a cross-sectional study in 800 school children 9-12 years old in the city of León, Nicaragua. The clinical oral examinations to identify caries experience were undertaken by two trained and certified examiners. Sociodemographic, socio-economic and behavioural data were collected using questionnaires. Negative binomial regression (NBR) and binary logistic regression (BLR) models were used to model caries experience and caries prevalence, respectively. Results: Mean DMFT index was 0.98 ± 1.74 and caries prevalence (DMFT > 0) was 37.9%. In the NBR model, the categories that increase the expected DMFT mean were: older age, female gender, presence of plaque, and if the school children received curative and curative/preventive dental care in the last year. In the BLR model, the odds of presenting with caries in the permanent dentition were increased in older children, those from large families, mothers with a positive dental attitude, and those school children who received curative and curative/preventive dental care in the last year. Conclusions: Using different models, we identified several sociodemographic, socio-economic, clinical and behavioural factors that modify the experience (NBR) and prevalence (BLR) of dental caries.

    Hodgkin's disease (HD) incidence in whites is described by age, sex, Rye histologic subtype and time period for ten US locations, using recently available data with Rye histologic diagnoses for most cases. Some distinctive features of incidence in young persons - stable childhood rates, and high and increasing rates in young adults, particularly women - resulted from the elevated rates of the Nodular Sclerosis (NS) subtype. NS was the only histologic form with a rising incidence. Unexpectedly, among middle-aged and older persons rates of all subtypes declined during the 1970s. HD incidence varied little across study regions and became more geographically homogeneous with time, notably among women. HD rates were positively correlated with regional socio-economic levels. In areas with the highest young adult incidence, higher risk also affected a broader age range, including older children. Rates for young adults were positively associated with community socioeconomic status but did not covary with older adult rates. Rates for the NS and Lymphocyte Predominance subtypes were inversely correlated across areas. NS incidence increased with community economic levels. These features suggest the incidence of HD in a well-developed country is not static but evolves, characterized by higher rates of NS in an increasingly broad age range of young, particularly female, adults, rising with small increments in socioeconomic status, and occurring over the relatively short study interval. 27 figures, 50 tables.

  14. Relative importance of climatic, geographic and socio-economic determinants of malaria in Malawi

    PubMed Central

    2013-01-01

    Background Malaria transmission is influenced by variations in meteorological conditions, which impact the biology of the parasite and its vector, but also socio-economic conditions, such as levels of urbanization, poverty and education, which impact human vulnerability and vector habitat. The many potential drivers of malaria, both extrinsic, such as climate, and intrinsic, such as population immunity are often difficult to disentangle. This presents a challenge for the modelling of malaria risk in space and time. Methods A statistical mixed model framework is proposed to model malaria risk at the district level in Malawi, using an age-stratified spatio-temporal dataset of malaria cases from July 2004 to June 2011. Several climatic, geographic and socio-economic factors thought to influence malaria incidence were tested in an exploratory model. In order to account for the unobserved confounding factors that influence malaria, which are not accounted for using measured covariates, a generalized linear mixed model was adopted, which included structured and unstructured spatial and temporal random effects. A hierarchical Bayesian framework using Markov chain Monte Carlo simulation was used for model fitting and prediction. Results Using a stepwise model selection procedure, several explanatory variables were identified to have significant associations with malaria including climatic, cartographic and socio-economic data. Once intervention variations, unobserved confounding factors and spatial correlation were considered in a Bayesian framework, a final model emerged with statistically significant predictor variables limited to average precipitation (quadratic relation) and average temperature during the three months previous to the month of interest. Conclusions When modelling malaria risk in Malawi it is important to account for spatial and temporal heterogeneity and correlation between districts. Once observed and unobserved confounding factors are allowed for

    Droughts and the socioeconomic impact it makes are expected to increase in the coming years due to climate change. Here, we review the possible changes in hazard and vulnerability posed by future droughts as a result of anthropogenic global warming in the state of Texas. An ensemble of downscaled and bias corrected meteorological and hydrologic projections representing the future scenarios were used for drought analysis. Quantification of the risk posed by droughts was then performed by considering a composite Drought Risk Index (DRI). DRI consists of two components: (1) Drought Hazard expressed in terms of joint drought magnitude and frequency of occurrence, and (2) Drought Vulnerability which is expressed in terms of the potential indicators representing the future socio-economic scenario of the study region. A set of drought hazard, vulnerability, and composite risk maps were then developed. These maps serve as an aid to identify the regions vulnerable to droughts in future, thus helping in development of mitigation strategies. The results are expected to be relevant for effective water resources management in a consistently drought prone state like Texas.

    The etiology of cancer is multifactorial. Various factors, including physical carcinogens, chemicals and viral carcinogens affect patients with known predisposing factors who subsequently develop malignancies. Here is a retrospective study of 18 patients who developed rare malignancies in clinical situations like xeroderma pigmentosum, tuberous sclerosis, neurofibromatosis, hereditary multiple exostosis, second malignancies due to radiotherapy and chronic irritation. The predisposing factors like chronic infection in leprosy, filariasis, poverty and ignorance leading to the chronicity of the lesion, lack of available health care facilities and socio-cultural background, i.e. consanguinity marriage in some community are responsible for the development of these rare malignancies. They were treated at A.H Regional Cancer Centre, Cuttack, Odisha, which is located at Eastern part of India for various malignancies, between January 1989 and January 2008. Malignancies that developed in patients with the above predisposing factors are being reported here due to their rarity and to highlight the impact of socio cultural background in developing these malignancies. Patients with above clinical situations should be kept under close observation for early detection of malignancy so their chances of survival can be improved. In addition, those oncogenic stimuli that initiated or propagated the malignancies, due to socio-economic factors, should be addressed promptly to prevent their eventual development.

  18. Diabetes and depression comorbidity and socio-economic status in low and middle income countries (LMICs): a mapping of the evidence

    PubMed Central

    2012-01-01

    Non-communicable diseases account for more than 50% of deaths in adults aged 15–59 years in most low income countries. Depression and diabetes carry an enormous public health burden, making the identification of risk factors for these disorders an important strategy. While socio-economic inequalities in chronic diseases and their risk factors have been studied extensively in high-income countries, very few studies have investigated social inequalities in chronic disease risk factors in low or middle-income countries. Documenting chronic disease risk factors is important for understanding disease burdens in poorer countries and for targeting specific populations for the most effective interventions. The aim of this review is to systematically map the evidence for the association of socio-economic status with diabetes and depression comorbidity in low and middle income countries. The objective is to identify whether there is any evidence on the direction of the relationship: do co-morbidities have an impact on socio-economic status or vice versa and whether the prevalence of diabetes combined with depression is associated with socio-economic status factors within the general population. To date no other study has reviewed the evidence for the extent and nature of this relationship. By systematically mapping the evidence in the broader sense we can identify the policy and interventions implications of existing research, highlight the gaps in knowledge and suggest future research. Only 14 studies were found to analyse the associations between depression and diabetes comorbidity and socio-economic status. Studies show some evidence that the occurrence of depression among people with diabetes is associated with lower socio-economic status. The small evidence base that considers diabetes and depression in low and middle income countries is out of step with the scale of the burden of disease. PMID:23181626

    This study presents a method for assessing conservation opportunity on private land based on landholders' socio-economic, behavioral, and farm characteristics. These characteristics include age, gender, education, level of off-farm income, farm size, proportion of remnant native vegetation on-farm, and ecological value of native vegetation on-farm. A sample of landholders who own greater than 2 ha of land in the South Australian Murray-Darling Basin region were sent a mail-based survey about their values and preferences for environmental management (N = 659, 52% response). Cross-tabulations and ANOVA statistical analysis techniques were used to compare the socio-economic attributes across three landholder classes: disengaged, moderately engaged, and highly engaged in native vegetation planting. Results indicate that highly engaged landholders were more likely to be female, formally educated, hobby farmers who managed small parcels of land and have high off-farm incomes, whereas disengaged landholders held significantly stronger farming connections (more farming experience, family have lived on the farm for more generations). Spatial analysis revealed area-specific differences in conservation opportunity and conservation priority. In some areas, properties of high ecological value were managed by highly engaged landholders, but nearby properties of high value were managed by moderately engaged or disengaged landholders. Environmental managers therefore cannot assume areas of high conservation priority will be areas of high conservation opportunity. At the regional scale, the potential for revegetation seems most promising within the moderately engaged landholder group considering the vast amount of land managed by this group in areas of high ecological value, particularly within the less represented Mallee and Coorong and Rangelands sub-regions. We suggest that incentive schemes which purchase conservation need to be targeted at disengaged landholders; mentoring

    2006-01-01

    The global obesity pandemic has been well-documented and widely discussed by the public, the media, health officials, the food industry and academic researchers. While the problem is widely recognised, the potential solutions are far less clear. There is only limited evidence to guide decisions as to how best to manage obesity in individuals and in populations. While widely viewed as a clinical and public health problem in developed countries, it is now clear that many developing countries also have to grapple with this problem or face the crippling healthcare costs resulting from obesity-related morbidity. There is also abundant evidence that obesity is socio-economically distributed. In developed countries persons of lower socio-economic position are more likely to be affected, while in developing countries, it is often those of higher socio-economic position who are overweight or obese. The aim of this paper is to briefly review the evidence that links socio-economic position and obesity, to discuss what is known about underlying mechanisms, and to consider the role of social, physical, policy and cultural environments in explaining the relationships between socio-economic position and obesity. We introduce the concept of 'resilience' as a potential theoretical construct to guide research efforts aimed at understanding how some socio-economically disadvantaged individuals manage to avoid obesity. We conclude by considering an agenda to guide future research and programs focused on understanding and reducing obesity among those of low socio-economic position.

  1. Determining age and sex of American coots

    Reliable techniques for age and sex determination of migrating and wintering American Coots (Fulica americana) have not been available. Breeding coots can be ages through age 3 by tarsal color (birds 4 years and older were placed in a 4+ age class) (Crawford 1978), and males and females have sex-specific behaviors and calls while on breeding territories (Gullion 1950, 1952). Externally, juvenile coots differ from adults in having gray (as opposed to white) bills and brown (as opposed to red) eyes to an age of 75 days (Gullion 1954-394). Bill color changes to white by about 120 days. No quantitative data have been available, however, on the proportion of juveniles retaining these traits throughout fall and early winter. Nonbreeding coots can be ages as juvenile or adult by internal examination of the thickness of the wall of the bursa of Fabricius, although bursal depth does not predictably decline with age (Fredrickson 1968). Attempts to sex coots by single external measurements of combinations of measurements have met with mixed success. Eight-five percent of 101 fall migrants in Wisconsin could be sexed by the length of the metatarsus-midtoe including claw by using 139.5 mm as a cutoff point (Burton 1959), whereas 88% of 67 coots in California were correctly sexed by the length of the metatarsus-midtoe without claw using 127.5 mm as the cutoff point (Gullion 1952). Two-hundred-thirty-two of 291 coots collected in Iowa, however, were in the zone of overlap between the sexes for this measurement (Fredrickson 1968). Previous studies attempting to develop aging and sexing techniques for American Coots have been limited to a few study sites or to 1 season or year, often failing to take geographical, annual, and seasonal morphological variation into account (e.g., Visser 1976, Fjeldsa 1977). We designed the present study to refine and quantify external and internal age and sex criteria for postbreeding coots, with the objective of defining techniques applicable for all

    2015-09-01

    The socio-economic and cultural evolution in the last decades encouraged a significant process of transformation of the life conditions in advanced societies, particularly the average duration of the life of the elderly population, which since the second half of the past century has increased by about 60%, becoming from an average of fifty years to about eighty two for women and eighty for men. This phenomenon enables scholars and in particular demography scholars, to assume that in 2030 the number of elderly persons will reach about two billion worldwide. This development of an increasingly longer life expectancy, justifies the trust in the great progress that characterizes our society. The rapid growth of this segment of population, due to the improved living conditions and the related progress in science, technology and medicine, in addition to its positive aspects, also includes negative elements, which already affect the Welfare State and, more generally, the public administration that is called to fill the gaps that the transformation of the family and kinship networks have treated with indifference. The problems of the increasingly long-lived, is not freed from new elements of negativity related to the physical and mental decline that leads to the development of new diseases in addition to those already present, ans is increasingly motivated to seek the best remedies to shorten or eliminate the diseases of the elderly. In this context, Depression assumes a central dimension which will surely be a central concern for the economic, social and health impact and for the multitude of changes that put in crisis many of the traditional institutions. This work aims to analyze through a careful review of the scientific literature, the causes of the spread of this disease, the diagnostic difficulties and possible solutions for prevention and care.

The aim of the present study was to describe sex- and age-specific distributions of anthropometric measurements and body composition in Mexican older adults. The methods included in the present study were assessment of height, weight, BMI, calf circumference (CC), waist circumference (WC) and hip circumference (HC) as well as knee height in a sample of 8883 Mexican adults aged 60 years and above and the estimation of sex- and age-specific differences in these measures. Results of the study (n 7865, 54% women) showed that men are taller, have higher BMI, and larger WC than women, whereas women presented higher prevalence of obesity and adiposity. Overall prevalence of underweight was 2·3% in men and 4·0% in women, with increasing prevalence with advancing age. Significant differences were found by age group for weight, height, WC, HC, CC, BMI and knee height (P<0·001), but no significant differences in waist-hip circumference were observed. Significant differences between men and women were found in height, weight, circumferences, BMI and knee height (P<0·001). These results, which are consistent with studies of older adults in other countries, can be used for comparison with other Mexican samples including populations living in the USA and other countries with similar developmental and socio-economic conditions. This information can also be used as reference in clinical settings as a tool for detection of individuals at risk of either underweight or overweight and obesity.

    The relative contribution of early or later life Socio Economic Position (SEP) to later life health is not fully understood and there are alternative hypotheses about the pathways through which they may influence health. We used data from the English Longitudinal Study of Ageing with a formal approach for the identification of mediating factors in order to investigate alternative hypotheses about life course influences on biomarkers of later life health. We found that early life SEP predicts physical health at least 65 years later. However, a more complicated pattern of associations than that implied by previous findings was also observed. Age group specific effects emerged, with current SEP dominating the effect on later life physical health and fibrinogen levels in participants under 65, while early life SEP had a more prominent role in explaining inequalities in physical health for men and women over 75. We extend previous findings on mid adulthood and early old age, to old age and the beginnings of late old age. The complexity of our findings highlights the need for further research on the mechanisms that underlie the association between SEP and later life health.

    Routine childhood immunizations against measles and DPT are part of the World Health Organization's (WHO) Expanded Program on Immunization (EPI) set up in 1974, with the aim of reducing childhood morbidity and mortality. Despite this, immunization rates are sub-optimal in developing countries such as India, with wide heterogeneity observed across districts and socio-economic characteristics. The aim of this paper is to examine district-level variations in the propensity to vaccinate a child in India for measles and DPT3, and analyse the extent to which these immunizations are given age-inappropriately, either prematurely or delayed. The present study uses data from the Indian District Level Household Survey (DLHS-3) collected in 2008, and the final sample contains detailed information on 42157 children aged between 12 and 60 months, across 549 Indian districts for whom we have complete information on immunization history. Our empirical study analyses: (i) the district-level average immunization rates for measles and DPT3, and (ii) the extent to which these immunizations have been given age-appropriately. A key contribution of this paper is that we link the household-level data at the district level to data on availability and proximity to health infrastructure and district-level socio-economic factors. Our results show that after controlling for an array of socio-economic characteristics, across all our models, the district's income per capita is a strong predictor of better immunization outcomes for children. Mother's education level at the district-level has a statistically significant and positive influence on immunization outcomes across all our models.

    The link between reproductive health, sexual and reproductive right, and development was highlighted at the International Conference on Population and Development held in Egypt. Developmental disparities are related to socio-economic differences which have led to the identification of distinct socio-economic classifications of nations. Human development represents the socioeconomic standing of any nation, in addition to literacy status and life expectancy. Africa accounts for 25% of the world's landmass but remains the world's poorest continent. Nigeria, the most populous country in Africa, has policies and programmes geared towards the improvement of its socio-economic standing and overal development, with little positive result. Reproductive health is a panacea towards reversing the stalled socio-economic growth of Nigeria as evident from the linkage between reproductive health and development, highlighted in Millennium Development Goals 3, 4, 5 and 6. Fast tracking Nigeria's development requires implementation of reproductive health policies and programmes targeted on women and children.

    Research has previously shown a gap of near 0.5 of a standard deviation (SD) in cognition and language development between the top and bottom household wealth quartile in children aged 6–42 months in a large representative sample of low- and middle-income families in Bogota, using the Bayley Scales of Infant and Toddler Development. The gaps in fine motor and socio-emotional development were about half that size. Developmental deficits increased with age. The current study explored the associations amongst child development, household socio-economic status (SES), and a set of potential mediating variables—parental characteristics, child biomedical factors, and the quality of the home environment—in this sample. We ran mediation tests to quantify the contribution of these variables to the SES gap, and explored the role of age as a moderator. Parental education, particularly maternal education, and the quality of the home environment mediated the SES gap in all outcomes examined. Height-for-age mediated a small amount of the deficit in language scales only. More educated mothers provided better home stimulation than less educated mothers and the home environment partly mediated the effect of maternal education. These results suggested that in interventions aimed at promoting child development, those focusing on the quality of the home environment should be effective. PMID:27885311

    This study examined the effects of socio-economic and behavioural factors on childhood malnutrition in Yemen. The three anthropometric indicators such as height-for-age, weight-for-height and weight-for-age are used to examine the nutritional status of children aged less 5 years in Yemen. The independent variables include background characteristics, behavioural risk factors and illness characteristics. Data for the study come the most recent Yemen Demographic and Health Survey, a nationally representative sample, conducted in Yemen in 1997. Logistic regression analysis is used to estimate the odds of being malnourished. The three anthropometric indicators show high to very high levels of child malnutrition in Yemen. The prevalence of stunting and underweight is so widespread that almost every other child under the age of 5 is either stunted or underweight. Social, economic and behavioural factors show very significant association with childhood malnutrition. The study results indicate the importance of social and behavioural factors in describing childhood malnutrition in Yemen. The study results will help develop nutritional and health promotion policies in order to improve childhood malnutrition in this country.

    Multinomial logistic regression analysis was used to develop statistical model that can predict the probability of breast cancer in Southern Karnataka using the breast cancer occurrence data during 2007-2011. Independent socio-economic variables describing the breast cancer occurrence like age, education, occupation, parity, type of family, health insurance coverage, residential locality and socioeconomic status of each case was obtained. The models were developed as follows: i) Spatial visualization of the Urban- rural distribution of breast cancer cases that were obtained from the Bharat Hospital and Institute of Oncology. ii) Socio-economic risk factors describing the breast cancer occurrences were complied for each case. These data were then analysed using multinomial logistic regression analysis in a SPSS statistical software and relations between the occurrence of breast cancer across the socio-economic status and the influence of other socio-economic variables were evaluated and multinomial logistic regression models were constructed. iii) the model that best predicted the occurrence of breast cancer were identified. This multivariate logistic regression model has been entered into a geographic information system and maps showing the predicted probability of breast cancer occurrence in Southern Karnataka was created. This study demonstrates that Multinomial logistic regression is a valuable tool for developing models that predict the probability of breast cancer Occurrence in Southern Karnataka.

    This paper describes characters on the wing plumage of the mallard that indicate age and sex. A key outlines a logical order in which to check age and sex characters on wings. This method was tested and found to be more than 95 percent reliable, although it was found that considerable practice and training with known-age specimens was required to achieve this level of accuracy....The implications of this technique and the sampling procedure it permits are discussed. Wing collections could provide information on production, and, if coupled with a banding program could permit seasonal population estimates to be calculated. In addition, representative samples of wings would provide data to check the reliability of several other waterfowl surveys.

    The integration of socio-economic and environmental objectives is a major challenge in developing strategies for sustainable landscapes. We investigated associations between socio-economic variables, landscape metrics and measures of forest condition in the context of Portugal. The main goals of the study were to 1) investigate relationships between forest conditions and measures of socio-economic development at national and regional scales, 2) test the hypothesis that a systematic variation in forest landscape metrics occurs according to the stage of socio-economic development and, 3) assess the extent to which landscape metrics can inform strategies to enhance forest sustainability. A ranking approach and statistical techniques such as Principal Component Analysis were used to achieve these objectives. Relationships between socio-economic characteristics, landscape metrics and measures of forest condition were only significant in the regional analysis of municipalities in Northern Portugal. Landscape metrics for different tree species displayed significant variations across socio-economic groups of municipalities and these differences were consistent with changes in characteristics suggested by the forest transition model. The use of metrics also helped inform place-specific strategies to improve forest management, though it was also apparent that further work was required to better incorporate differences in forest functions into sustainability planning.

    Abstract This paper describes the current prevalence and time trends of childhood obesity worldwide, and the association between childhood obesity and socio-economic status (SES). Childhood obesity has become a global public health crisis. The prevalence is highest in western and industrialized countries, but still low in some developing countries. The prevalence also varies by age and gender. The WHO Americas and eastern Mediterranean regions had higher prevalence of overweight and obesity (30-40%) than the European (20-30%), south-east Asian, western Pacific, and African regions (10-20% in the latter three). A total of 43 million children (35 million in developing countries) were estimated to be overweight or obese; 92 million were at risk of overweight in 2010. The global overweight and obesity prevalence has increased dramatically since 1990, for example in preschool-age children, from approximately 4% in 1990 to 7% in 2010. If this trend continues, the prevalence may reach 9% or 60 million people in 2020. The obesity-SES association varies by gender, age, and country. In general, SES groups with greater access to energy-dense diets (low-SES in industrialized countries and high-SES in developing countries) are at increased risk of being obese than their counterparts.

    Background Mortality and morbidity have been shown to follow a ‘social gradient’ in Canada and many other countries around the world. Comparatively little, however, is known about whether ageing amplifies, diminishes or sustains socio-economic inequalities in health. Methods Growth curve analysis of seven cycles of the Canadian National Population Health Survey (n=13 682) for adults aged 20 and older at baseline (1994/95). The outcome of interest is the Health Utilities Index Mark 3, a measure of health-related quality of life (HRQL). Models include the deceased so as not to present overly optimistic HRQL values. Socio-economic position is measured separately by household-size-adjusted income and highest level of education attained. Results HRQL is consistently highest for the most affluent and the most highly educated men and women, and is lower, in turn, for middle and lower income and education groups. HRQL declines with age for both men and women. The rate of the decline in HRQL, however, was related neither to income nor to education for men, suggesting stability in the social gradient in HRQL over time for men. There was a sharper decline in HRQL for upper-middle and highest-income groups for women than for the poorest women. Conclusion HRQL is graded by both income and education in Canadian men and women. The grading of HRQL by social position appears to be ‘set’ in early adulthood and is stable through mid- and later life. PMID:21441176

    Mortality among males with 47,XYY is increased due to a host of conditions and diseases. Clinical studies have suggested a poorer educational level and social adaptation among 47,XYY persons. We wanted to study the socio-economic profile in 47,XYY persons and the impact on mortality. We conducted a register study using several Danish nationwide registries. 206 47,XYY men and 20,078 controls from the background population and 1,049 controls with Klinefelter syndrome were included. Information concerning marital status, fatherhood, education, income, and retirement were obtained. Compared to the background population, 47,XYY men had fewer partnerships, were less likely to become fathers, had lower income and educational level, and retired at an earlier age. The mortality among 47,XYY men was significantly increased with a hazard ratio (HR) of 3.6 (95% confidence interval: 2.6-5.1). Adjusting for marital and educational status reduced this HR to 2.7. Compared to Klinefelter syndrome, 47,XYY had significantly fewer partnerships, were more likely to become fathers, but had lower income. Mortality among 47,XYY men was increased compared with Klinefelter syndrome with a HR of 1.36. The results show a severely inferior outcome in all investigated socio-economic parameters compared to the background population and an affected profile compared with Klinefelter syndrome, even though the population in Denmark has equal and free access to health care and education. We conclude that 47,XYY is often associated with a poorer socio-economic profile, which partly explains the increased mortality.

    Background: Stroke is the leading cause of adult disability. Stroke, which affects mostly the productive age group, leaves about 65% of its victims disabled, leads to increased loss of manpower both at individual and national levels. Little is known about the socio-economic burden of the disease in terms of its impacts on the individual, family and community both directly and indirectly in Sub-Sahara Africa region and Zambia at large. Aim: The study was aimed at assessing the socio-economic impact of stroke households in Livingstone district, Zambia. Subjects and Methods: A total of 50 households were randomly selected from the registers of Livingstone General Hospital. Self-administered questionnaires and focus group discussions were used to collect quantitative and qualitative data respectively. The data was analyzed using Statistical Package for Social Sciences version 16 (IBM Corporation) and content analysis. Chi-square test was used to make associations between variables. Results: The social impacts on the victim were depression, difficult to get along with, resentfulness, apathy, needy, separation, divorce, general marital problems, neglect on the part of the victim and fear. The economic impacts were loss of employment, reduced business activity and loss of business on the part of the victim. Economic activities such as food provision, payment of school fees, accommodation were affected as a result of stroke and this led to financial insecurities in households with lost incomes in form of salaries and businesses. The activities forgone by stroke households were food provision, housing and education. The study also revealed an association between period of stroke and relationship changes (P < 0.001). Gender and family relationship changes were highly associated (P < 0.00), as more females than males experienced relationship changes. Conclusion: The results of the present study show that stroke has considerable socio-economic impact on households in

    It is well known that gross social crises greatly influence the change in epidemiological features of suicide. The aim of this study is to determine whether the social-economic crisis in Yugoslavia influenced the change in epidemiological features of suicide in the region of Nis (southeastern Serbia). The material included death certificates for 1987-1999. The rates were calculated per 100,000 inhabitants (1991 Census) and standardization was performed by direct method (Segi's world population was used as standard population). Generally, trends for suicide rates in the region of Nis from 1987 to 1999 have decreasing tendency among both sexes. The average annual suicide rate in the region during the period 1987/1989 (relatively economically and politically stable) was 14.8 among males, and 6.8 among females. In 1999 (maximum influence of socio-economical and political crisis) suicide rate among males was 13.8 and among females it was 3.7. The decrease in suicide rate in females can be observed in all age groups, and in males in the age groups 15-29 and 50-64. During 1999, compared to 1987/1989, the increase in the number of suicides is perceived in the summer months (1999 -41.5%; 95% CI: 30.8-52.2%; 1987/ 1989 -23.8%; 95% CI: 18.9-28.7%), as well as the decrease of suicide on Monday (1987/1989 -21.2%; 95% CI: 16.2-26.1%; 1999 -9.8%; 95% CI: 3.4 16.2%). During 1999 the rate of suicides committed by fire arms increased (from 8.1 to 14.5%), while there was a decrease in poisoning, in both males (from 26.3 to 9.7%; p < 0.05) and females (from 39.1 to 10.0%; p < 0.05). During 1999 significant changes in epidemiological features of suicide were registered, compared to 1987/1989. These changes were probably enhanced by changed socio-economic factors (primarily war action and the bombing of Serbia, as well as the decline of standard of living and other aspects of economic and political crisis), which requires additional, more complete and thorough research.

    Age of woodcock (Philohela minor) can be accurately determined throughout the year by differences in pattern, color, and wear of secondary feathers. Immature woodcock retain most secondaries during the postjuvenal molt that begins in July or August and ends in October. In contrast, subadults (first-year adults) and older woodcock molt all secondaries during the postnuptial molt beginning in June or July and ending in October. Retention of juvenal secondaries by immatures and molt of these feathers by adults form the basis for age determination. Sex of woodcock can be accurately determined by width of the outer three primaries, which are conspicuously narrower on males.

    Childhood wasting is a global problem and is significantly more pronounced in low and middle income countries like Bangladesh. Socio Economic Status (SES) and Water, Sanitation and Hygiene (WASH) practices may be significantly associated with wasting. Most previous research is consistent about the role of SES, but the significance of WASH in the context of wasting remains ambiguous. The effect of SES and WASH on weight for length (WHZ) is examined using a Structural Equation Model (SEM) to explicitly describe the direct and indirect role of WASH in the context of SES.A nationally representative survey of 10,478 Bangladeshi children under 5 were examined. An expert defined SEM was used to construct latent variables for SES and WASH. The SEM included a direct pathway from SES to WHZ and an indirect pathway from SES to WHZ via WASH along with regression of relevant covariates on the outcome WHZ and the latent variables. Both SES (p<0.01) and WASH (p<0.05) significantly affect WHZ. SES (p<0.01) also significantly affects WASH. Other structural components showed that child’s age (p<0.01) affects WHZ and types of residence (p<0.01) affects SES. WASH practices at least partially mediate the association between SES and wasting status. WASH and SES are both significantly associated with WHZ. PMID:28278161

    Background In Denmark patients are entitled to rehabilitation regardless of socio-economic status (SES). During this process therapists have to balance cost effectiveness with providing equal treatment. Aim To investigate whether occupational therapists and physiotherapists were influenced by the patient's SES. Material and method An experimental factorial vignette survey was used. Four different vignettes describing fictitious patient cases with different SES variables were randomly allocated to therapists working in somatic hospitals. Thereafter, the therapists judged specific clinical situations and general attitudes in relation to the patient's SES. Chi-square was used to test the statistical association between the variables. Results No statistically significant associations were found between the specific clinical situations and the patient's SES. A statistical significant association was found between general attitudes and the patient's SES. Subgroup analysis revealed a statistically significant association between the therapist's gender, age, and the therapeutic judgement in relation to SES. Conclusion In the specific clinical situations, Danish therapists seem to maintain their professional ethical principles, although they might face ethical dilemmas during their clinical decision-making. In order to prevent and resolve these dilemmas, they have to be made explicit. However, further research on how SES influences the health care professional's judgement is warranted.

    Introduction Rotavirus vaccine efficacy ranges from >90% in high socio-economic settings (SES) to 50% in low SES. With the imminent introduction of rotavirus vaccine in low SES countries, understanding reasons for reduced efficacy in these settings could identify strategies to improve vaccine performance. Methods We developed a mathematical model to predict rotavirus vaccine efficacy in high, middle and low SES based on data specific for each setting on incidence, protection conferred by natural infection and immune response to vaccination. We then examined factors affecting efficacy. Results Vaccination was predicted to prevent 93%, 86% and 51% of severe rotavirus gastroenteritis in high, middle and low SES, respectively. Also predicted was that vaccines are most effective against severe disease and efficacy declines with age in low but not high SES. Reduced immunogenicity of vaccination and reduced protection conferred by natural infection are the main factors that compromise efficacy in low SES. Discussion The continued risk of severe disease in non-primary natural infections in low SES is a key factor underpinning reduced efficacy of rotavirus vaccines. Predicted efficacy was remarkably consistent with observed clinical trial results from different SES, validating the model. The phenomenon of reduced vaccine efficacy can be predicted by intrinsic immunological and epidemiological factors of low SES populations. Modifying aspects of the vaccine (e.g. improving immunogenicity in low SES) and vaccination program (e.g. additional doses) may bring improvements. PMID:22879893

    High levels of social capital may be associated with positive mental health in adults. However, quantifying the various dimensions of social capital has presented a challenge due in part to the diverse definitions and measures used. Data from a representative, population-wide survey of Australian adults aged 16 years and older were used to investigate the links between dimensions of social capital and mental health morbidity. Social capital comprised three constructs and was measured at the individual level: feelings of trust and safety, community participation and neighbourhood connections and reciprocity. Mental health was measured by the 10-item Kessler (K10) instrument and assessed symptoms of psychological distress (i.e., depression and anxiety) over the previous month. Community participation showed a weak, and neighbourhood connections and reciprocity a moderate association with distress. Having higher levels of trust and feeling safe were consistently associated with low levels of psychological distress, after adjusting for socio-demographic characteristics and health conditions. The results clearly demonstrate that having trust in people, feeling safe in the community and having social reciprocity are associated with lower risk of mental health distress. The implications for conceptualising and measuring the individual and collective (contextual) dimensions of social capital are discussed. The findings also suggest the importance of examining the interrelationships between socio-economic status, social capital and mental health for community-dwelling adults.

    SummaryThe importance of securing water supply necessitates that all options be explored. Research has indicated that demand on water catchments can be substantially decreased when a large proportion of households reuse greywater and/or install rainwater tanks. This paper reports on an internet survey completed by 354 households residing in the Australian Capital Territory and surrounding regions. Statistical analyses examined the relationship between socio-economic and psychological variables and the likelihood of the garden being irrigated with greywater and/or rainwater. The results show income, gender, age and education could not differentiate residents who were irrigating their garden with water from a tank from residents who were not. Residents who used tank water on their gardens had a higher self-reported understanding of a range of water supply options. Female participants and lower income residents were more likely to use greywater on their garden. Participants who irrigated the garden with greywater were more likely to judge various other water collection and recycling proposals as being appropriate. General concerns about water collection and reuse risks were not found to predict which households used tank water and/or greywater on their garden.

    In Greater Mekong Sub-region (GMS), economic liberalization and deregulation facilitated by GMS Regional Economic Corporation Program (GMS-ECP) has triggered urbanization in the region. However, the urbanization rate and its linkage to socio-economic activities are ambiguous. The objectives of this paper are to: (a) determine the changes in urban area from 1972 to 2013 using remote sensing data, and (b) analyse the relationships between urbanization with respect to socio-economic activities in central Laos. The study employed supervised classification and human visible interpretation to determine changes in urbanization rate. Regression analysis was used to analyze the correlation between the urbanization rate and socio-economic variables. The result shows that the urban area increased significantly from 1972 to 2013. The socio-economic variables such as school enrollment, labour force, mortality rate, water source and sanitation highly correlated with the rate of urbanization during the period. The study concluded that identifying the highly correlated socio-economic variables with urbanization rate could enable us to conduct a further urbanization simulation. The simulation helps in designing policies for sustainable development.

    SETTING Tuberculosis (TB) affected households in impoverished shantytowns, Lima, Peru. OBJECTIVE To evaluate socio-economic interventions for strengthening TB control by improving uptake of TB care and prevention services. DESIGN Barriers to TB control were characterised by interviews with TB-affected families. To reduce these barriers, a multidisciplinary team offered integrated community and household socio-economic interventions aiming to: 1) enhance uptake of TB care by education, community mobilisation and psychosocial support; and 2) reduce poverty through food and cash transfers, microcredit, microenterprise and vocational training. An interim analysis was performed after the socio-economic interventions had been provided for 2078 people in 311 households of newly diagnosed TB patients for up to 34 months. RESULTS Poverty (46% earned socio-economic interventions were associated with increases in household contact TB screening (from 82% to 96%); successful TB treatment completion (from 91% to 97%); patient human immunodeficiency virus testing (from 31% to 97%); and completion of preventive therapy (from 27% to 87%; all P < 0.0001). CONCLUSIONS Socio-economic interventions can strengthen TB control activities. PMID:21740659

    Methods for identifying the sex and age of the Akiapolaau (Hemignathus munroi), an endangered honeycreeper found only on the island of Hawaii, were developed by examination and measurement of 73 museum specimens and 24 live birds captured in mist nests. Akiapolaau probably undergo a single annual molt, with most birds molting between February and July. The mottled juvenal plumage is replaced by a first basic plumage characterized by yellowish-gray or yellowish-green underparts and often by retained wingbars. Male Akiapolaau may not attain adult plumage until their third molt. In adult females, only the throat and upper breast become yellow, whereas in adult males the superciliaries, cheeks, and entire underparts are yellow. Adult males have greater exposed culmen, gonys, wing chord, tail, and tarsus lengths than do females. Akiapolaau in first prebasic molt or older can be identified as to sex by culmen length, that of males being >23.4 mm.

    We present methods to determine the age and sex of Akohekohe (Palmeria dolei), an endangered Hawaiian honeycreeper, developed on the basis of 45 museum specimens and 91 live birds captured on the island of Maui. Akohekohe retained all Juvenal primaries, some Juvenal secondaries, and some body feathers after the first prebasic molt; they attained full adult plumage after the second prebasic molt. Retention of brown Juvenal body feathers, especially on the head, distinguished most birds in the first basic plumage from adults, which have a full complement of distinctive, black lanceolate body feathers with white, gray, or orange tips. Male Akohekohe were heavier than females and had longer wing, tail, and tarsometatarsus lengths. We present a linear discriminant function to sex both adults and juveniles using lengths of their wing and tarsometatarsus.

    This study examines traffic-related air pollution in London in relation to area- and individual-level socio-economic position (SEP). Mean air pollution concentrations were generally higher in postcodes of low SEP as classified by small-area markers of deprivation (Index of Multiple Deprivation (IMD) domains) and by the postcode-level ACORN geodemographic marker. There were exceptions, however, including reversed directions of associations in central London and for SEP markers relating to education. ACORN predicted air pollution independently of IMD and explained additional variation at the postcode level, indicating the potential value of using both markers in air pollution epidemiology studies. By contrast, after including IMD and ACORN there remained little relationship between air pollution and individual-level SEP or smoking, suggesting limited residual socio-economic confounding in epidemiological studies with comprehensive area-level adjustment.

  8. Local knowledge and socio-economic determinants of traditional medicines' utilization in livestock health management in Southwest Nigeria

    Smallholder livestock farmers in Nigeria utilize traditional medicines derived from medicinal plants (PMs) for the maintenance of their animals' health. This study was designed to determine the PMs used in the study area and their level of utilization by livestock farmers, compare the level of utilization of PMs across the three states surveyed and identify the socio-economic factors influencing farmer's utilization of PMs. Thirty-five PMs were identified. Farmers had considerable knowledge about the identified PMs but about 80.0% of them used the PMs to poor/moderate extent. There were statistical differences in the utilization level of PMs among the three states. Six socio-economic variables were found to be statistically significant in influencing PMs' utilization. Farmer's age, household size, distance to the nearest veterinary hospital/clinic and extent of travels, had positive effects while negative effects were exhibited by farm income and number of heads of livestock. It was concluded that there was considerable knowledge about PMs and that utilization of PMs varied between the three states. It was recommended that local knowledge of PMs be preserved in the study area through screening and documentation. PMID:22239949

    While deleterious consequences of smoking on health have been widely publicized, in many developing countries, smoking prevalence is high and increasing. Little is known about the dynamics underlying changes in smoking behavior. This paper examines socio-economic and demographic characteristics associated with smoking initiation and quitting in Mexico between 2002 and 2010. In addition to the influences of age, gender, education, household economic resources and location of residence, changes in marital status, living arrangements and health status are examined. Drawing data from the Mexican Family Life Survey, a rich population-based longitudinal study of individuals, smoking behavior of individuals in 2002 is compared with their behavior in 2010. Logistic models are used to examine socio-demographic and health factors that are associated with initiating and quitting smoking. There are three main findings. First, part of the relationship between education and smoking reflects the role of economic resources. Second, associations of smoking with education and economic resources differ for females and males. Third, there is considerable heterogeneity in the factors linked to smoking behavior in Mexico indicating that the smoking epidemic may be at different stages in different population subgroups. Mexico has recently implemented fiscal policies and public health campaigns aimed at reducing smoking prevalence and discouraging smoking initiation. These programs are likely to be more effective if they target particular socio-economic and demographic sub-groups. PMID:23888371

    The incidence of multiple sclerosis is increasing in Danish women. Their risk of developing multiple sclerosis has more than doubled in 25 years while it has remained virtually unchanged for men. The explanation for these epidemiological changes should be sought in the environment as they are too rapid to be explained by gene alterations. We investigated the effect of numerous biological social physical and chemical environmental exposures in different periods of life. These data were available from population-based registries and were used in a case-control approach. This study database included all multiple sclerosis cases (n = 1403) from the Danish MS Registry with clinical onset between 2000 and 2004 as well as 35,045 controls drawn by random from the Danish Civil Registration System and matched by sex year of birth and residential municipality at the reference year. Having newborn children reduced the risk of multiple sclerosis (MS) in women but not in men. Childbirths reduced the risk of MS by about 46% during the following 5 years. Even pregnancies terminated early had a protective effect on the risk of developing MS suggesting a temporary immunosuppression during pregnancy. Our data on social behaviour regarding educational level income and relationship stability did not indicate reverse causality. A greater likelihood to be exposed to common infections did not show any effect on the risk of MS neither in puberty nor in adulthood. Socio-economic status and lifestyle expressed in educational level and sanitary conditions in youth were not associated with the risk of MS.

    The data presented is part of the findings from a four-year collaborative research project between Universiti Putra Malaysia, the Institute for Medical Research and the Ministry of Health Malaysia. The project assessed the nutritional status of the major functional groups in Peninsular Malaysia. Mukim Sayong and Pulau Kemiri in the District of Kuala Kangsar, Perak were two of the subdistricts selected to represent small rubber holdings in Peninsular Malaysia. This paper attempts to analyse the socio-economic profile of the households and the nutritional status of children below 9 years of age. A total of 307 households were studied. Approximately 63% of the households were involved in rubber activities and the majority of them were hired tappers. The average monthly income of the households was RM467 and the income ranged between RM30 to RM2120. Based on the per capita poverty line income of RM84.38, it was found that 14.1% of the households earned less than RM42.19, which can be considered as hard-core poor, while 32.7% were poor (monthly per capita income between RM42.19 and RM84.38). Slightly more than half (52.7%) earned income above the poverty line. The average family size was 4.5, ranging from 1 through to 16. The majority of the heads of households (56.6%) had between 3 and 6 years of education, and 14.5% did not receive any formal education. The prevalence of stunting among children 0-5 years of age was 26%, while 31.5% were underweight and 3.8% wasted. Among children aged between 5 and 9 years, almost the same pattern of nutritional status was noted. The overall percentages of stunting, underweight and wasting among these children were 29.2%, 26.1% and 0.62%, respectively. Analysis on nutritional status according to income level showed a noticeable difference in the prevalence of malnutrition in children above and below the poverty line income. The Student's t-test indicated significant differences in weight-for-age and weight-for-height between the two

    Attainment of 70 years life expectancy by 2020 is one of the millennium development goals in Nigeria. This study examined the socio-economic determinants of life expectancy in Nigeria using data from 1980-2011. Judging from the endogeneity feature of the variables, A VAR and VECM frameworks were employed. Socio-economic features were proxy by secondary school enrolment, government expenditure on health, per capita income, unemployment rate and the Naira foreign exchange rate. It was found that, the conventional socio-economic variables such as per capita income, education and government expenditure on health considered to be highly effective in determining life expectancy of developing countries are not significant in the case of Nigeria. The study however suggests that, life expectancy in Nigeria could be improved if attention is given to quality of government health expenditure, unemployment and measures to halt the depreciation of the Nigerian Naira against major foreign currency.

    Climate change has significant repercussions on the natural environment, triggering obvious changes in the natural processes that have a severe socio-economic impact on the coastal zone; where a great number of human activities are concentrated. So far, the estimation of coastal vulnerability was based primarily on the natural processes and less on socio-economic variables, which would assist in the identification of vulnerable areas. The present investigation proposes a methodology to examine the vulnerability of a highly touristic area in the Island of Crete to an expected sea level rise of up to ~40 cm by the year 2100, according to the A1B scenario of IPCC 2007. The methodology includes the combination of socio-economic indicators into a GIS-based coastal vulnerability index for wave-induced erosion. This approach includes three sub-indices that contribute equally to the overall index. The sub-indices refer to coastal forcing, socio-economic and coastal characteristics. All variables are ranked on a 1-5 scale with 5 indicating higher vulnerability. The socio-economic sub-index includes, as indicators, the population of the study area, cultural heritage sites, transport networks, land use and protection measures. The coastal forcing sub-index includes the frequency of extreme events, while the Coastal Vulnerability Index includes the geological variables (coastal geomorphology, historical coastline changes, and regional coastal slope) and the variables representing the marine processes (relative sea level rise, mean significant wave height, and tidal range). The main difficulty for the estimation of the index lies in assessing and ranking the socio-economic indicators. The whole approach was tested and validated through field and desktop studies, using as a case study the Elouda bay, Crete Isl., an area of high cultural and economic value, which combines monuments from ancient and medieval times, with a very high touristic development since the 1970s.

  15. Long-term care use and socio-economic status in Belgium: a survival analysis using health care insurance data

    PubMed Central

    2013-01-01

    Background The small but growing literature on socio-economic inequality in morbidity among older persons suggests that social inequalities in health persist into old age. A largely separate body of literature looks at the predictors of long-term care use, in particular of institutional care. Various measures of socio-economic status are often included as control variables in these studies. Review articles generally conclude that the evidence for such variables being a predictor for institutionalization is “inconclusive”. In this paper we look at the association among older persons in Belgium between one particular measure of socio-economic status – preferential status in public health care insurance – and first use of home long-term care and residential care. Preferential status entitles persons to higher reimbursement rates for health care from the public health care insurance system and is conditional on low income. We also study whether preferential status is related to the onset of five important chronic conditions and the time of death. Methods We use survival analysis; the source of the data is a large administrative panel of a sample representative for all older persons in Belgium (1,268,740 quarterly observations for 69,562 individuals). Results We find a strong association between preferential status and the likelihood of home care use, but for residential care it is small for men and non-existent for women. We also find that preferential status is significantly related to the chance of getting two out five chronic conditions – COPD and diabetes, but not dementia, hip fracture and Parkinson’s disease – and to the probability of dying (not for women). For home care use and death, the association with preferential status declines with increasing age from age 65 onwards, such that it is near zero for those aged around 90 and older. Conclusion We find clear associations between an indicator of low income and home care use, some chronic

    This paper examines the relationship between adolescent behaviour, television viewing and family socio-economic status (SES) using the Canadian National Longitudinal Survey of Children and Youth (NLSCY). The effect of television viewing on adolescents' behaviour, ranging from pro-social to aggressive, and whether this effect is moderated by family socio-economic status is investigated. An adolescent fixed effects model is used to estimate the effect of television viewing on behaviour. The results indicate that the effect of television viewing varies between males and females. Family SES has a role in the effect of television on adolescents' behaviour, although the results do not distinguish between the two proposed hypotheses.

    The Arabian Gulf, one of the driest parts of the world, is already passing the water scarcity line as defined by the World Health Organization (WHO). The scarcity of renewable water resources and the growing discrepancy between demand and supply of water is a major challenge. Water scarcity is further worsened by rapidly growing demands due to rapid population growth, unsustainable consumption, climate change and weak management institutions and regulations. Water scarcity erodes the socio-economic sustainability of the communities that depend on the depleting storage. In this paper, an analysis of the water security situation within the Arabian Gulf region and the consequent socio-economic implications is presented.

    Methods to sex and age Palila (Loxioides bailleui), an endangered Hawaiian finch restricted to subalpine woodlands on Hawai'i, were identified on the basis of measurements and plumage characteristics of 17 museum specimens and 96 known-age, live Palila. Palila undergo a single annual molt during September-December following the breeding season. Presence of a complete or partial wingbar distinguishes hatch-year and second-year Palila from after-second-year birds. Adult male Palila are distinguished from females by a distinct napeline and lt 30% gray feathers intermixed with yellow feathers on the head. The black or gray feathers of the lores and chin of males are darker than those on the back, whereas the lores and chin of females are lighter or of the same shade as back feathers.

  20. Integration of Socio-Economic Measures in Benefit-Cost Analysis for Groundwater Remediation

    Groundwater quality is a major concern since sources of contamination are common and degraded water quality has severe economic and health impacts to the society. Management of contaminated groundwater resources has been a challenge due to limited resources committed to monitor and remediate a large number of contaminated sites. Therefore, there is a prominent question on the optimal allocation of resources for additional data collection and actual remedial measures. In this work, we extended the risk assessment methodology under subsurface heterogeneity and population variability proposed by others to estimate individuals' willingness-to-pay(WTP) for a proposed risk reduction by adding socio-economic measures. We introduced one of the early applications of welfare measures namely, health state, utility, and WTP concepts to study the benefits and costs of collecting additional data to reduce uncertainty for groundwater remediation. The proposed framework considered uncertainty due to subsurface heterogeneity and public health risk through a utility theory based approach that can be used in decision-making. Our framework replaced costly contingent valuation approaches and used a meta analysis which considered a theoretical structure on population age, income, and health state and used empirical estimates from previous contingent valuation methods. We also performed sensitivity analysis on important variables such as WTP and utility levels. Our findings showed that health state and age have vital impacts on WTP. The predictions of WTP trends are consistent with patterns expected in economic theory. We illustrated the proposed framework by evaluating two scenarios of gathering additional information to better describe subsurface heterogeneity. In this example we considered a small addition of data at a correlation scale of 112 m versus a large addition of data at a correlation scale of 22 m. The results showed the two scenarios have annual individuals' WTP of 258 and

    The aim of this study was to investigate factors that influence morbidity patterns and health-seeking decisions in an urban slum community. Data were collected between May and August 2003 as part of the ongoing Nairobi urban demographic surveillance system and were analysed to identify factors that influence morbidity patterns and health-seeking decisions. The results show that the factors that influenced morbidity were the child's age, ethnicity and type of toilet facility. Predictors for seeking health care were the child's age, type and severity of illness, survival of father and mother, mother's education, mother's work status and wealth class. The conclusions drawn show that economic resources fall short in preventing child illnesses where children live in poor environmental conditions. However, by enhancing access to health care services, socio-economic status is critical for mitigating disease burden among children in slum settlements.

    With rapid economic development and urbanization, land use in China has experienced huge changes in recent years; and this will probably continue in the future. Land use problems in China are urgent and need further study. Rapid land-use change and economic development make China an ideal region for integrated land use change studies, particularly the examination of multiple factors and global-regional interactions in the context of global economic integration. This paper presents an integrated modeling approach to examine the impact of global socio-economic processes on land use changes at a regional scale. We develop an integrated model system by coupling a simple global socio-economic model (GLOBFOOD) and regional spatial allocation model (CLUE). The model system is illustrated with an application to land use in China. For a given climate change, population growth, and various socio-economic situations, a global socio-economic model simulates the impact of global market and economy on land use, and quantifies changes of different land use types. The land use spatial distribution model decides the type of land use most appropriate in each spatial grid by employing a weighted suitability index, derived from expert knowledge about the ecosystem state and site conditions. A series of model simulations will be conducted and analyzed to demonstrate the ability of the integrated model to link global socioeconomic factors with regional land use changes in China. The results allow an exploration of the future dynamics of land use and landscapes in China.

    The mechanism of bilateral interaction between natural water cycle evolution and socio-economic development has been obscured in current research due to the complexity of the hydrological process and the socio-economic system. The coupling of economic model CGE (Computable General Equilibrium) and distributed hydrological model WEP (Water and Energy transfer Processes) provides a model-based tool for research on response and feedback of water cycle and social development, as well as economic prospects under the constraint of water resources. On one hand, water policies, such as water use limitation and water price adjustment under different levels of socio-economic development, are to be evaluated by CGE model as assumed conditions and corresponding results of water demand could be put into WEP model to simulate corresponding response during the whole process of water cycle. On the other hand, variation of available water resources quantity under different scenarios simulated by WEP model may provide proper limitation for water demand in CGE model, and corresponding change of economic factors could indicate the influence of water resources constraints on socio-economic development. The research is believed to be helpful for better understanding of bilateral interaction between water and society.

    We study the impact of socio-economic status on enrollment and study decisions in higher education. We use a discrete choice approach to distinguish between three channels. First, students from disadvantaged backgrounds may be more sensitive to the costs of education. Second, they may have lower preferences for education. Third, they may have…

  10. Socio-economic health differences in The Netherlands: a review of recent empirical findings.

    1992-02-01

    Evidence on variation in the frequency of health problems between socio-economic groups in the Dutch population has accumulated rapidly in recent years. This paper presents a review of these recent data. It is clear now that a lower socio-economic status is associated with a higher frequency of a wide range of health problems. This negative association has consistently been found for the following health indicators: birth weight; adult body height; prevalence of health complaints; prevalence of many chronic conditions; prevalence of disability; incidence of long-term work incapacity; perceived general health; adult mortality. Inconsistent findings were reported for: children's body height; prevalence of some chronic conditions; incidence of sickness absence (short-term work incapacity); perinatal mortality. The magnitude of the differences varies from study to study, and possibly from health problem to health problem. In studies categorizing the study population in 3-6 hierarchically ordered socio-economic groups on the basis of either education or occupational status, the Relative Risks (of the lowest versus the highest socio-economic group) mostly lie between 1 and 2. Exceptions are prevalence of disability and incidence of long-term work incapacity where Relative Risks between 2 and 4 have been found. A direct comparison with data from other countries is problematic, but at first sight the differences as observed in the Netherlands seem to be of the same order of magnitude as those observed in other industrialized countries. Although most Relative Risks imply 'weak associations' from a technical-epidemiological point of view, the Population Attributable Risks are substantial (generally between 0.25 and 0.40), underlining the public health impact of socio-economic health differences. Information on trends in health inequalities over time is limited to children's body height and adult mortality. For children's body height a substantial decrease of inequalities was

  11. Suicide in young adults: psychiatric and socio-economic factors from a case–control study

    PubMed Central

    2014-01-01

    Background Suicide in young adults remains an important public health issue in Australia. The attributable risks associated with broader socioeconomic factors, compared to more proximal psychiatric disorders, have not been considered previously in individual-level studies of young adults. This study compared the relative contributions of psychiatric disorder and socio-economic disadvantage associated with suicide in terms of relative and attributable risk in young adults. Method A population-based case–control study of young adults (18–34 years) compared cases of suicide (n = 84) with randomly selected controls (n = 250) from population catchments in New South Wales (Australia), with exposure information collected from key informant interviews (for both cases and controls). The relative and attributable risk of suicide associated with ICD-10 defined substance use, affective, and anxiety disorder was compared with educational achievement and household income, adjusting for key confounders. Prevalence of exposures from the control group was used to estimate population attributable fractions (PAF). Results Strong associations were evident between mental disorders and suicide for both males and females (ORs 3.1 to 18.7). The strongest association was for anxiety disorders (both males and females), followed by affective disorders and substance use disorders. Associations for socio-economic status were smaller in magnitude than for mental disorders for both males and females (ORs 1.1 to 4.8 for lower compared to high SES groups). The combined PAF% for all mental disorders (48% for males and 52% for females) was similar in magnitude to socio-economic status (46% for males and 58% for females). Conclusion Socio-economic status had a similar magnitude of population attributable risk for suicide as mental disorders. Public health interventions to reduce suicide should incorporate socio-economic disadvantage in addition to mental illness as a potential target for

    This study sought to determine the contributions of socio-economic position and health insurance enrollment in explaining racial disparities in preventive dental visits (PDVs) among South Africans. Data on the dentate adult population participating in the last South African Demographic and Health Survey conducted during 2003–2004 (n = 6,312) was used. Main outcome measure: Reporting making routine yearly PDVs as a preventive measure. Education, material wealth index and nutritional status indicated socio-economic position. Multi-level logistic regression analysis was conducted to determine the predictors of PDVs. A variant of Blinder-Oaxaca decomposition analysis was also conducted. Health insurance coverage was most common among Whites (70%) and least common among black Africans (10.1%) in South Africa. Similarly, a yearly PDV was most frequently reported by Whites (27.8%) and least frequently reported among black Africans (3.1%). Lower education and lower material wealth were associated with lower odds of making PDVs. There was significant interaction between location (urban/rural) and education (p = 0.010). The racial and socio-economic differences in PDVs observed in urban areas were not observed in rural areas. In the general dentate population, having health insurance significantly increased the odds of making PDVs (OR = 4.32; 3.04–6.14) and accounted for 40.3% of the White/non-White gap in the probability of making PDVs. Overall, socio-economic position and health insurance enrollments together accounted for 55.9% (95% CI = 44.9–67.8) of the White/non-White gap in PDVs. Interventions directed at improving both socio-economic position and insurance coverage of non-White South Africans are likely to significantly reduce racial disparities in PDVs. PMID:23282482

  18. Participatory Approach to Long-Term Socio-Economic Scenarios as Building Block of a Local Vulnerability and Risk Assessment Tool - The Case Study Lienz (East-Tyrol)

    Risks associated with climate change are mostly still understood and analyzed in a sector- or hazard-specific and rarely in a systemic, dynamic and scenario-based manner. In addition, socio-economic trends are often neglected in local vulnerability and risk assessments although they represent potential key determinants of risk and vulnerability. The project ARISE (Adaptation and Decision Support via Risk Management Through Local Burning Embers) aims at filling this gap by applying a participatory approach to socio-economic scenario building as building block of a local vulnerability assessment and risk management tool. Overall, ARISE aims at developing a decision support system for climate-sensitive iterative risk management as a key adaptation tool for the local level using Lienz in the East-Tyrol as a test-site City. One central building block is participatory socio-economic scenario building that - together with regionalized climate change scenarios - form a centrepiece in the process-oriented assessment of climate change risks and vulnerability. Major vulnerabilities and risks may stem from the economic performance, the socio-economic or socio-demographic developments or changes in asset exposition and not from climate change impacts themselves. The IPCC 5th assessment report underlines this and states that for most economic sectors, the impact of climate change may be small relative to the impacts of other driving forces such as changes in population growth, age, income, technology, relative prices, lifestyle, regulation, governance and many other factors in the socio-economy (Arent et al., 2014). The paper presents the methodology, process and results with respect to the building of long-term local socio-economic scenarios for the City of Lienz and the surrounding countryside. Scenarios were developed in a participatory approach using a scenario workshop that involved major stakeholders from the region. Participatory approaches are increasingly recognized as

    Diet quality is influenced by socio-economic and geographical factors. The present study sought to assess whether adolescents' diet quality is affected by their parents' socio-economic status and whether the relationship between these factors is similar in northern and southern Europe. Data collected in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study in eight European countries were analysed. Dietary intake data were recorded via repeated 24 h recalls (using specifically developed HELENA Dietary Intake Assessment Tool software) and converted into an adolescent-specific Diet Quality Index (DQI-AM). Socio-economic status was estimated through parental educational level (Par-Educ-Lev) and parental occupation level (Par-Occ-Lev) as reported by the adolescents in a specific questionnaire. The DQI-AM data were then analysed as a function of Par-Educ-Lev and Par-Occ-Lev in northern European countries (Austria, Belgium, France, Germany and Sweden) and southern European countries (Greece, Italy and Spain). We studied a total of 1768 adolescents (age 14.7 (SD 1.3) years; percentage of girls: 52.8%; 1135 and 633 subjects from northern and southern Europe, respectively). On average, the DQI-AM score was higher in southern Europe than in northern Europe (69.1 (SD 0.1) v. 60.4 (SD 2.8), respectively; P < 0.001; Δ = 12.6%). The DQI was positively correlated with both paternal and maternal Par-Educ-Lev. However, this association was more pronounced in northern Europe than in southern Europe (P interaction = 0.004 for the mother and 0.06 for the father). The DQI was also positively correlated with Par-Occ-Lev (all P trends < 0.01), but this correlation was independent of the geographical area (P interaction = 0.51 for the mother and 0.50 for the father). In conclusion, Par-Educ-Lev and Par-Occ-Lev are associated with diet quality in adolescents in Europe. However, this association differs between northern Europe and southern Europe.

  20. Identifying solutions to increase participation in physical activity interventions within a socio-economically disadvantaged community: a qualitative study

    PubMed Central

    2014-01-01

    Background There is an urgent need to increase population levels of physical activity, particularly amongst those who are socio-economically disadvantaged. Multiple factors influence physical activity behaviour but the generalisability of current evidence to such ‘hard-to-reach’ population subgroups is limited by difficulties in recruiting them into studies. Also, rigorous qualitative studies of lay perceptions and perceptions of community leaders about public health efforts to increase physical activity are sparse. We sought to explore, within a socio-economically disadvantaged community, residents’ and community leaders’ perceptions of physical activity (PA) interventions and issues regarding their implementation, in order to improve understanding of needs, expectations, and social/environmental factors relevant to future interventions. Methods Within an ongoing regeneration project (Connswater Community Greenway), in a socio-economically disadvantaged community in Belfast, we collaborated with a Community Development Agency to purposively sample leaders from public- and voluntary-sector community groups and residents. Individual semi-structured interviews were conducted with 12 leaders. Residents (n = 113), of both genders and a range of ages (14 to 86 years) participated in focus groups (n = 14) in local facilities. Interviews and focus groups were recorded, transcribed verbatim and analysed using a thematic framework. Results Three main themes were identified: awareness of PA interventions; factors contributing to intervention effectiveness; and barriers to participation in PA interventions. Participants reported awareness only of interventions in which they were involved directly, highlighting a need for better communications, both inter- and intra-sectoral, and with residents. Meaningful engagement of residents in planning/organisation, tailoring to local context, supporting volunteers, providing relevant resources and an ‘exit strategy

    Studies were carried out from June 1974 to May 1975 on the socio-economic status, health and nutritional status of the people in 4 villages, in the irrigation area of the Nong Wai Pioneer Agricultural Project of Khon Kaen Province, Northeast Thailand. The result obtained were compared with those in 2 non-irrigated villages in the same province, in order to identify the health and nutritional problems which might arise during the water resource development in the irrigation area. It was found that in the irrigated villages 90% of the peoples were farmers, while in the non-irrigated villages all were farmers. The socio-economic status of the people in the irrigated villages was much better than those in the non-irrigated ones. The income per family in the former was about three times greater than that in the latter. In the study of the health conditions of the villagers, the vulnerable age group including pre-school children under 7 years of age and school children in the elementary school class 1 and class 2, aged 7-9 years old, served as subjects for investigation. Haematological and physical examinations revealed many children with mild to moderate anaemia, vitamin B2 deficiency and a few cases of hepatomegaly. Anaemic children were found to be more prevalent in the non-irrigated villages than in the irrigated area. The overall parasitic infection rates in children in the irrigated and non-irrigated villages were similar with respect to severity of the infection. Hookworm infection, opisthorchiasis, strongyloidiasis and giardiasis were the leading parasitic infections, while amoebiasis was rare. Ascariasis and trichuriasis were not found. However, the first two helminthic infections had a low grade of intensity. The nutritional status of pre-school children, showed that there were more children with good growth in the irrigated villages than in the non-irrigated one. Serum proteins, albumin and globulin, and urinary urea nitrogen-creatinine ratio revealed normal

    1992-12-01

    Kenya's national survey data have shown patterns of fertility decline in the more socioeconomically advantaged regions. In the central areas, where urbanization and economic development is the highest, fertility has begun to decline rapidly. The lowest fertility was in Nairobi capital region; the Coast Province also experienced recent fertility decline. Fertility has remained high in the Western Province and in Nyanza, Rift Valley, and Eastern Provinces. The case study of Kisii district in Nyanza Province was used to illustrate the preconditions of high fertility. The district is an agriculturally rich region that includes rounded, steep-sided hills and narrow valleys. The district is a primary producer of cash crops such as coffee, tea, and pyrethrum, and other food crops including high-yielding varieties of maize. Farm size varies between 0.11 and 2.2 hectares and farms are owner occupied. All cultivable land is in use with traditional farming methods. Tractors are used in flat areas by 11.6% of farmers. 69.3% of farmers use fertilizers, but only 32% use insecticides and pesticides. Population density is 395 persons per square kilometer. The total fertility rate is 8.2 compared to 7.7 for the nation. 6% currently used contraception, and 23% have ever used. Fertility preferences of women under 25 years old is 6.9 children. Most farm labor, even among the wealthy farmers, is family labor organized by age and gender. Women are responsible for planting, weeding, harvesting and household chores. Male off-farm employment increases the agricultural production responsibilities of women. Only mothers of sons can control property and gain prestige. Modernization and land shortages have pressured families to increase nonfarm employment.

    Background The primary objective of this study was to make the first step in the modelling of pharmaceutical demand in Italy, by deriving a weighted capitation model to account for demographic differences among general practices. The experimental model was called ASSET (Age/Sex Standardised Estimates of Treatment). Methods and Major Findings Individual prescription costs and demographic data referred to 3,175,691 Italian subjects and were collected directly from three Regional Health Authorities over the 12-month period between October 2004 and September 2005. The mean annual prescription cost per individual was similar for males (196.13 euro) and females (195.12 euro). After 65 years of age, the mean prescribing costs for males were significantly higher than females. On average, costs for a 75-year-old subject would be 12 times the costs for a 25–34 year-old subject if male, 8 times if female. Subjects over 65 years of age (22% of total population) accounted for 56% of total prescribing costs. The weightings explained approximately 90% of the evolution of total prescribing costs, in spite of the pricing and reimbursement turbulences affecting Italy in the 2000–2005 period. The ASSET weightings were able to explain only about 25% of the variation in prescribing costs among individuals. Conclusions If mainly idiosyncratic prescribing by general practitioners causes the unexplained variations, the introduction of capitation-based budgets would gradually move practices with high prescribing costs towards the national average. It is also possible, though, that the unexplained individual variation in prescribing costs is the result of differences in the clinical characteristics or socio-economic conditions of practice populations. If this is the case, capitation-based budgets may lead to unfair distribution of resources. The ASSET age/sex weightings should be used as a guide, not as the ultimate determinant, for an equitable allocation of prescribing resources to

    2011-01-01

    Background Diarrhoea disease which has been attributed to poverty constitutes a major cause of morbidity and mortality in children aged five and below in most low-and-middle income countries. This study sought to examine the contribution of individual and neighbourhood socio-economic characteristics to caregiver's treatment choices for managing childhood diarrhoea at household level in sub-Saharan Africa. Methods Multilevel multinomial logistic regression analysis was applied to Demographic and Health Survey data conducted in 11 countries in sub-Saharan Africa. The unit of analysis were the 12,988 caregivers of children who were reported to have had diarrhoea two weeks prior to the survey period. Results There were variability in selecting treatment options based on several socioeconomic characteristics. Multilevel-multinomial regression analysis indicated that higher level of education of both the caregiver and that of the partner, as well as caregivers occupation were associated with selection of medical centre, pharmacies and home care as compared to no treatment. In contrast, caregiver's partners' occupation was negatively associated with selection medical centre and home care for managing diarrhoea. In addition, a low-level of neighbourhood socio-economic disadvantage was significantly associated with selection of both medical centre and pharmacy stores and medicine vendors. Conclusion In the light of the findings from this study, intervention aimed at improving on care seeking for managing diarrhoea episode and other childhood infectious disease should jointly consider the influence of both individual SEP and the level of economic development of the communities in which caregivers of these children resides.

    A community-based cross-sectional study was carried out among Aboriginal schoolchildren aged 7-12 years living in remote areas in Pos Betau, Pahang, Malaysia to investigate the potential determinants influencing the cognitive function and educational achievement of these children. Cognitive function was measured by intelligence quotient (IQ), while examination scores of selected school subjects were used in assessing educational achievement. Blood samples were collected to assess serum Fe status. All children were screened for soil-transmitted helminthes. Demographic and socio-economic data were collected using pre-tested questionnaires. Almost two-thirds (67·6 %) of the subjects had poor IQ and most of them (72·6 %) had insufficient educational achievement. Output of the stepwise multiple regression model showed that poor IQ was significantly associated with low household income which contributed the most to the regression variance (r2 0·059; P = 0·020). Low maternal education was also identified as a significant predictor of low IQ scores (r2 0·042; P = 0·043). With educational achievement, Fe-deficiency anaemia (IDA) was the only variable to show significant association (r2 0·025; P = 0·015). In conclusion, the cognitive function and educational achievement of Aboriginal schoolchildren are poor and influenced by household income, maternal education and IDA. Thus, effective and integrated measures to improve the nutritional and socio-economic status of rural children would have a pronounced positive effect on their education.

    Climate change effects are expected to be more severe for some segments of society than others. In Mexico, climate variability associated with climate change has important socio-economic and environmental impacts. From the central mountainous region of eastern Veracruz, Mexico, we analyzed data of total annual precipitation and mean annual temperature from 26 meteorological stations (1922-2008) and from General Circulation Models. We developed climate change scenarios based on the observed trends with projections to 2025, 2050, 2075, and 2100, finding considerable local climate changes with reductions in precipitation of over 700 mm and increases in temperature of ~9°C for the year 2100. Deforested areas located at windward were considered more vulnerable, representing potential risk for natural environments, local communities, and the main crops cultivated (sugarcane, coffee, and corn). Socio-economic vulnerability is exacerbated in areas where temperature increases and precipitation decreases.

    The trade in soybean, an important animal feed product, exemplifies the environmental and socio-economic impact of global markets and global agricultural policy. This paper analyses the impact of increasing production of soybean in the exporting countries (deforestation and grassland conversion) as well as in importing regions (decrease in permanent grassland by substitution of grass as feed). Ecosystem services monetary values were used to calculate the environmental and socio-economic impact of observed land use changes. This is balanced against the economic value of the global soybean trade. The results prove that consumption choices in one region have real effects on the supply of ecosystem services at a large spatial scale. Conclusively, solutions to make this global market more sustainable are discussed. PMID:27244079

    The trade in soybean, an important animal feed product, exemplifies the environmental and socio-economic impact of global markets and global agricultural policy. This paper analyses the impact of increasing production of soybean in the exporting countries (deforestation and grassland conversion) as well as in importing regions (decrease in permanent grassland by substitution of grass as feed). Ecosystem services monetary values were used to calculate the environmental and socio-economic impact of observed land use changes. This is balanced against the economic value of the global soybean trade. The results prove that consumption choices in one region have real effects on the supply of ecosystem services at a large spatial scale. Conclusively, solutions to make this global market more sustainable are discussed.

    Assessing socio-economic vulnerability to climate change impacts to support regional decision-making is conceptually and practically challenging. We report on research that tested a rapid assessment approach of socio-economic vulnerability in Australia’s natural resource management regions. The approach focuses on regionally important economic sectors, identified using existing datasets, which are likely to be sensitive to climate change impacts. Disaggregated spatial representations of factors known to be associated with vulnerability function as multiple lines of evidence for highlighting intra-regional hotspots of high potential vulnerability. Our results show that a small number of factors based upon contextually relevant empirical evidence offers a low-cost, rapid assessment process, which is readily transferable across regions and provides end-users with guidance for interpreting the results within the context of regional conditions.

    The Jubba Environmental and Socio-economic Studies (JESS) investigated conditions in the Jubba Valley of southern Somalia. Projections from that baseline information were intended to elucidate changes likely to occur as a result of construction of a high dam near Baardheere and related developments. In particular, JESS was required to suggest ways of mitigating adverse impacts, enhancing potentially good impacts, and to draw up a program for future environmental and socio-economic monitoring. The report contains an analysis of the Terrestrial Ecology Baseline Studies (TEBS) section of the JESS project. Human use of biological resources is examined from the perspectives of land use, forestry, rangelands, and biological conservation. TEBS activities are used as the basis for a future monitoring program of terrestrial ecology.

    Estimation of sex and age in skeletons is essential in anthropological and forensic medicine investigations. The aim of the current study was to examine the potential of hyperostosis frontalis interna (HFI) as a criterion for determining sex and age in forensic cases. Macroscopic examination of the inner aspect of the frontal bone of 768 skulls (326 males and 442 females) aged 1 to 103, which had undergone a head computerized tomography scan, was carried out using the volume rendering technique. HFI was divided into two categories: minor and major. HFI is a sex- and age-dependent phenomena, with females manifesting significantly higher prevalence than males (p<0.01). In both females and males, prevalence of HFI increases as age increases (p<0.01). We present herein the probabilities of designating an unknown skull to a specific sex and age cohort according to the presence of HFI (standardized to age distribution in an Israeli population). Moreover, we present the probability of an individual belonging to a specific sex or age cohort according to age or sex (respectively) and severity of HFI. We suggest a valid, reliable, and easy method for sex and age identification of unknown skulls.

    Background Kenya and Uganda have reported different Human African Trypanosomiasis incidences in the past more than three decades, with the latter recording more cases. This cross-sectional study assessed the demographic characteristics, tsetse and trypanosomiasis control practices, socio-economic and cultural risk factors influencing Trypanosoma brucei rhodesiense (T.b.r.) infection in Teso and Busia Districts, Western Kenya and Tororo and Busia Districts, Southeast Uganda. A conceptual framework was postulated to explain interactions of various socio-economic, cultural and tsetse control factors that predispose individuals and populations to HAT. Methods A cross-sectional household survey was conducted between April and October 2008. Four administrative districts reporting T.b.r and lying adjacent to each other at the international boundary of Kenya and Uganda were purposely selected. Household data collection was carried out in two villages that had experienced HAT and one other village that had no reported HAT case from 1977 to 2008 in each district. A structured questionnaire was administered to 384 randomly selected household heads or their representatives in each country. The percent of respondents giving a specific answer was reported. Secondary data was also obtained on socio-economic and political issues in both countries. Results Inadequate knowledge on the disease cycle and intervention measures contributed considerable barriers to HAT, and more so in Uganda than in Kenya. Gender-associated socio-cultural practices greatly predisposed individuals to HAT. Pesticides-based crop husbandry in the 1970's reportedly reduced vector population while vegetation of coffee and banana's and livestock husbandry directly increased occurrence of HAT. Livestock husbandry practices in the villages were strong predictors of HAT incidence. The residents in Kenya (6.7%) applied chemoprophylaxis and chemotherapeutic controls against trypanosomiasis to a larger extent than

    A comprehensive assessment of the impacts of climate change on agro-ecosystems over this century is developed, up to 2080 and at a global level, albeit with significant regional detail. To this end an integrated ecological–economic modelling framework is employed, encompassing climate scenarios, agro-ecological zoning information, socio-economic drivers, as well as world food trade dynamics. Specifically, global simulations are performed using the FAO/IIASA agro-ecological zone model, in conjunction with IIASAs global food system model, using climate variables from five different general circulation models, under four different socio-economic scenarios from the intergovernmental panel on climate change. First, impacts of different scenarios of climate change on bio-physical soil and crop growth determinants of yield are evaluated on a 5′×5′ latitude/longitude global grid; second, the extent of potential agricultural land and related potential crop production is computed. The detailed bio-physical results are then fed into an economic analysis, to assess how climate impacts may interact with alternative development pathways, and key trends expected over this century for food demand and production, and trade, as well as key composite indices such as risk of hunger and malnutrition, are computed. This modelling approach connects the relevant bio-physical and socio-economic variables within a unified and coherent framework to produce a global assessment of food production and security under climate change. The results from the study suggest that critical impact asymmetries due to both climate and socio-economic structures may deepen current production and consumption gaps between developed and developing world; it is suggested that adaptation of agricultural techniques will be central to limit potential damages under climate change.

    Several global strategies for protected area (PA) expansion have been proposed to achieve the Convention on Biological Diversity's Aichi target 11 as a means to stem biodiversity loss, as required by the Aichi target 12. However, habitat loss outside PAs will continue to affect habitats and species, and PAs may displace human activities into areas that might be even more important for species persistence. Here we measure the expected contribution of PA expansion strategies to Aichi target 12 by estimating the extent of suitable habitat available for all terrestrial mammals, with and without additional protection (the latter giving the counterfactual outcome), under different socio-economic scenarios and consequent land-use change to 2020. We found that expanding PAs to achieve representation targets for ecoregions under a Business-as-usual socio-economic scenario will result in a worse prognosis than doing nothing for more than 50% of the world's terrestrial mammals. By contrast, targeting protection towards threatened species can increase the suitable habitat available to over 60% of terrestrial mammals. Even in the absence of additional protection, an alternative socio-economic scenario, adopting progressive changes in human consumption, leads to positive outcomes for mammals globally and to the largest improvements for wide-ranging species.

    Background Snakebite represents a significant health issue worldwide, affecting several million people each year with as many as 95,000 deaths. India is considered to be the country most affected, but much remains unknown about snakebite incidence in this country, its socio-economic impact and how snakebite management could be improved. Methods/Principal Findings We conducted a study within rural villages in Tamil Nadu, India, which combines a household survey (28,494 people) of snakebite incidence with a more detailed survey of victims in order to understand the health and socio-economic effects of the bite, the treatments obtained and their views about future improvements. Our survey suggests that snakebite incidence is higher than previously reported. 3.9% of those surveyed had suffered from snakebite and the number of deaths corresponds to 0.45% of the population. The socio-economic impact of this is very considerable in terms of the treatment costs and the long-term effects on the health and ability of survivors to work. To reduce this, the victims recommended improvements to the accessibility and affordability of antivenom treatment. Conclusions Snakebite has a considerable and disproportionate impact on rural populations, particularly in South Asia. This study provides an incentive for researchers and the public to work together to reduce the incidence and improve the outcomes for snake bite victims and their families. PMID:24278244

    What is the role of social interactions in the creation of price bubbles? Answering this question requires obtaining collective behavioural traces generated by the activity of a large number of actors. Digital currencies offer a unique possibility to measure socio-economic signals from such digital traces. Here, we focus on Bitcoin, the most popular cryptocurrency. Bitcoin has experienced periods of rapid increase in exchange rates (price) followed by sharp decline; we hypothesize that these fluctuations are largely driven by the interplay between different social phenomena. We thus quantify four socio-economic signals about Bitcoin from large datasets: price on online exchanges, volume of word-of-mouth communication in online social media, volume of information search and user base growth. By using vector autoregression, we identify two positive feedback loops that lead to price bubbles in the absence of exogenous stimuli: one driven by word of mouth, and the other by new Bitcoin adopters. We also observe that spikes in information search, presumably linked to external events, precede drastic price declines. Understanding the interplay between the socio-economic signals we measured can lead to applications beyond cryptocurrencies to other phenomena that leave digital footprints, such as online social network usage.

    An estuary area is a typical ecosystem where a vast array of fish breed to enlarge populations. These regions are made productive by organic material in the form of foodstuff, while receiving sunlight sufficient enough to illuminate the brackish waters. These zones must be protected due to their fertile waters and surrounding fertile land. Estuary areas are threatened by nearby landfill and waste debris along and upstream of the river, which consequently contaminate the estuary zone. Socio-economic conditions of the community also affect the sustainability of the estuary. In this case, the Socio-Economic Spatial Model, based on Geographical Information System (GIS) and trade off analysis, were used to elaborate the ecosystem sustainability in the Cimandiri estuary, West Java. This research also uses the temporal analysis of land use change upstream and monitors the community activity around the estuary. The research showed a change in the spatial and temporal land use consequently altering the watershed and the socio-economic analysis showed the community use of the estuary as unsustainable for the region and ecosystems within.

    Background Breast cancer remains a major cause of morbidity and mortality among women in the US, and despite numerous studies documenting racial disparities in outcomes, the survival difference between Black and White women diagnosed with breast cancer continues to widen. Few studies have assessed whether observed racial disparities in outcomes vary by insurance type e.g. Medicare/Medicaid versus private insurance. Differences in coverage, availability of networked physicians, or cost-sharing policies may influence choice of treatment and treatment outcomes, even after patients have been hospitalized, effects of which may be differential by race. Purpose The aim of this analysis was to examine hospitalization outcomes among patients with a primary diagnosis of breast cancer and assess whether differences in outcome exist by insurance status after adjusting for age, race/ethnicity and socio-economic status. Methods We obtained data on over 67,000 breast cancer patients with a primary diagnosis of breast cancer for this cross-sectional study from the 2007-2011 Healthcare Cost and Utilization project Nationwide Inpatient Sample (HCUP-NIS), and examined breast cancer surgery type (mastectomy vs. breast conserving surgery or BCS), post-surgical complications and in-hospital mortality. Multivariable regression models were used to compute estimates, odds ratios and 95% confidence intervals. Results Black patients were less likely to receive mastectomies compared with White women (OR: 0.80, 95% CI: 0.71 - 0.90), regardless of whether they had Medicare/Medicaid or Private insurance. Black patients were also more likely to experience post-surgical complications (OR: 1.41, 95% CI: 1.12-1.78) and higher in-hospital mortality (OR: 1.57, 95%: 1.21-2.03) compared with White patients, associations that were strongest among women with Private insurance. Women residing outside of large metropolitan areas were significantly more likely to receive mastectomies (OR: 1.89, 95% CI: 1

    The present study aimed to investigate socio-economic disparities in food and nutrient intakes among young Irish women. A total of 221 disadvantaged and seventy-four non-disadvantaged women aged 18-35 years were recruited. Diet was assessed using a diet history protocol. Of the total population, 153 disadvantaged and sixty-three non-disadvantaged women were classified as plausible dietary reporters. Food group intakes, nutrient intakes and dietary vitamin and mineral concentrations per MJ of energy consumed were compared between the disadvantaged and non-disadvantaged populations, as was compliance with dietary fibre, macronutrient and micronutrient intake guidelines. The disadvantaged women had lower intakes than the non-disadvantaged women of fruit, vegetables, fish, breakfast cereals, low-fat milk and wholemeal bread (all P< 0·001), yogurt (P= 0·001), low-fat spread (P= 0·002) and fresh meat (P= 0·003). They also had higher intakes of butter, processed red meats, white bread, sugar-sweetened beverages, fried potatoes and potato-based snacks (all P< 0·001) and full-fat milk (P= 0·014). Nutritionally, the disadvantaged women had higher fat, saturated fat and refined sugar intakes; lower dietary fibre, vitamin and mineral intakes; and lower dietary vitamin and mineral densities per MJ than their more advantaged peers. Non-achievement of carbohydrate (P= 0·017), fat (P< 0·001), saturated fat (P< 0·001), refined sugar (P< 0·001), folate (P= 0·050), vitamin C (P< 0·001), vitamin D (P= 0·047) and Ca (P= 0·019) recommendations was more prevalent among the disadvantaged women. Both groups showed poor compliance with Fe and Na guidelines. We conclude that the nutritional deficits present among these socially disadvantaged women are significant, but may be potentially ameliorated by targeted food-based interventions.

    Background Oral health has improved in France. However, there are still inequalities related to the socio-economic status. Objectives The aim of this study was to measure the prevalence of dental care needs in an adult population and to identify the demographic, socio-economic and behavioral variables that may explain variations in this parameter. Methods A cross-sectional analysis of the French SIRS cohort (n = 2,997 adults from the Paris region; 2010 data) was carried out to determine the prevalence of self-reported dental care needs relative to demographic, socio-economic and behavioral variables. A logistic regression model was used to identify the variables that were most strongly associated with the level of need. Results In 2010, the prevalence of the need for dental care in the SIRS cohort was 35.0% (95% CI [32.3–37.8]). It was lower in people with higher education levels (31.3% [27.9–34.6]), without immigrant background (31.3% [28.0–34.6]) and with comprehensive health insurance (social security + complementary health cover; 32.8% [30.2–35.4]). It decreased as the socio-economic status increased, but without following a strict linear change. It was also lower among individuals who had a dental check-up visit in the previous two years. In multivariate analyses, the socioeconomic variables most strongly associated with the need for dental care were: educational attainment (OR = 1.21 [1.02–1.44]), income level (OR = 1.66 [1.92–2.12]) and national origin (OR = 1.53 [1.26–1.86]). Conclusion These results confirm that the prevalence of dental care needs is higher among adults with low socio-economic status. Education level, income level and also national origin were more strongly associated with the need for dental care than insurance cover level. PMID:27441841

    With most youths now using the Internet and social networking sites (SNSs), the public has become increasingly concerned about risks posed by online predators. In response, lawmakers have begun to pass laws that ban or limit sex offenders' use of the Internet and SNSs. At the time of this article, 12 states and the federal government have passed legislation attempting to restrict or ban the use of SNSs by registered sex offenders. These laws have been successfully challenged in 4 states. In this article, we discuss examples of case law that illustrate evolving trends regarding Internet and social networking site restrictions on sex offenders on supervised release, as well as those who have already completed their sentences. We also review constitutional questions and empirical evidence concerning Internet and social networking use by sex offenders. To our knowledge, this is the first paper in the psychiatric literature that addresses the evolving legal landscape in reference to sex offenders and their use of the Internet and SNSs. This article is intended to help inform forensic mental health professionals who work with sex offenders on current concerns in this rapidly evolving legal landscape.

    This study examined the association between romanticism (operationalized as mean score on the Romantic Beliefs Scale) and age, sex, and ethnicity in a large community sample (N = 436). Age was negatively correlated with romanticism scores; as age increased, romanticism scores decreased. No sex differences were found; men and women had similar, moderate scores. Although ethnicity largely was unrelated to romanticism, Asian/Pacific Islander participants were significantly more romantic than were African-American participants.

    ♦ Background and Objectives: A large proportion of the patients on peritoneal dialysis (PD) in Brazil have low levels of education and family income. The present study assessed whether education level and family income are associated with baseline and longitudinal changes in health-related quality of life (HRQOL) scores during the first year of PD therapy. ♦ Methods: We evaluated 1624 incident patients from the Brazilian Peritoneal Dialysis Multicenter Study (BRAZPD) at baseline, and 486 of them after 12 months. The SF-36 was used to determine HRQOL and the Karnofsky index (KI), physical performance. ♦ Results: At baseline, patients received high KI scores compared with scores on the SF-36. The means of the mental and physical components at baseline and after 12 months were 39.9 ± 10.5 compared with 38.7 ± 11.7 and 41.8 ± 9.6 compared with 40.7 ± 9.8 respectively, which were not statistically different. A multivariate regression analysis showed that age, sex, diabetes, and cardiovascular disease were predictors of the mental component (respectively, β = 0.12, p < 0.001; β = 0.11, p < 0.001; β = -0.08, β = 0.007; and β = -0.07, p = 0.007) and that age, sex, diabetes, cardiovascular disease, hemoglobin, glucose, and creatinine were predictors of the physical component (respectively, β = -0.28, p < 0.001; β = 0.06, p = 0.009; β = -0.09, p = 0.002; β = -0.09, p = 0.001; β = 0.07, p = 0.004; β = -0.05, p = 0.040; and β = 0.05, p = 0.040). Education level and family income were not significantly associated with HRQOL (mental and physical components) in the multivariate regression. ♦ Conclusions: The results indicate that, as predictors, family income and education level have no impact on HRQOL, supporting the idea that socio-economic status should not be a barrier to the selection of PD as a treatment modality in Brazil.

    Few studies have assessed if Sweden's injury prevention work has been equally effective for children of different socio-economic backgrounds. The goal of this paper is to review the country's injury rates for children over time, stratified by socio-economic status (SES), to see if the effects are similar across SES levels. This study employs a retrospective case-control study design, using data from the hospitalisation records of 51,225 children, which were linked to family socio-economic data. Children and adolescents in families receiving social welfare benefits, and those living with single parents and mothers with less education had higher risks of injuries leading to hospitalisation. The population-based safety work over the past decades seems to have had only minor effects on reducing the impact of socio-economic based difference in injury risks to younger Swedes.

  9. Sex through the ages in China.

    PubMed

    Gross, A

    1981-11-01

    This brief article summarizes some of the Chinese sexual customs as revealed by Van Gulik, Needham, Levy, the author, and others. Chinese sexology is related to medicine, philosophy, and cosmology, all of which form a unified view of the universe. Cosmologically, the Chinese view human life as between the sun ("Ying"/man) and the earth ("Yin"/women). Energy particles from the sun continually enter the fingers, pass through arms, head, and body, and exit via the toes, while energy from the earth enter through the toes and exits through the fingers. Illness occurs if there is an imbalance in this system; if either flow stops death ensues. Chinese medicine corrects the energy flow of the sun and earth by means of needles, heat, gymnastics, massage, and sexual practices. Sexual practices, affect this energy exchange by special techniques for relieving physical complaints and ultra-orgasmic practices, sometimes termed "coitus reservatus." Chinese reason that if either man or woman achieve orgasm, then considerable energy can be produced over a longer duration, perhaps increasing one's health and longevity. These beliefs flourished from the Han Dynasty (202 B.C.-220 A.D.) until the close of the Ming Dynasty (1368-1644 A.D.). Practices during this period were to encourage orgasms for men and women with age, health, seasonal factors, and the need for heirs as variables in the practices. For example, in a Sui Dynasty (589-608 A.D.) sex manual, once a day is right for a healthy male of 30, while once every 5-10 days is proper for a 50 year old man. However, these techniques took time to learn and even "perversions" developed. Excesses encouraged the belief that sexual expression should be limited. The Confucionists during the Ching Dynasty (1644-1912) saw ultra-orgasmic exercises as a threat to government and encouraged its end. Ultra-orgasmic techniques may be used today at the village level and are inseparable from the Chinese language and literature. Male homosexuality

Methods Cross-sectional data from 9993 Chinese, Malay and Indian adults aged 40–80 years who participated in the Singapore Epidemiology of eye Diseases (2004–2011) in Singapore. Based on the presenting visual acuity (PVA) in the better-seeing eye, VI was categorized into normal vision (logMAR≤0.30), low vision (logMAR>0.30<1.00), and blindness (logMAR≥1.00). Any VI was defined as low vision/blindness in the PVA of better-seeing eye. Individual-level low-SES was defined as a composite of primary-level education, monthly income<2000 SGD and residing in 1 or 2-room public apartment. An area-level SES was assessed using a socio-economic disadvantage index (SEDI), created using 12 variables from the 2010 Singapore census. A high SEDI score indicates a relatively poor SES. Associations between SES measures and presence and severity of VI were examined using multi-level, mixed-effects logistic and multinomial regression models. Results The age-adjusted prevalence of any VI was 19.62% (low vision = 19%, blindness = 0.62%). Both individual- and area-level SES were positively associated with any VI and low vision after adjusting for confounders. The odds ratio (95% confidence interval) of any VI was 2.11(1.88–2.37) for low-SES and 1.07(1.02–1.13) per 1 standard deviation increase in SEDI. When stratified by unilateral/bilateral categories, while low SES showed significant associations with all categories, SEDI showed a significant association with bilateral low vision only. The association between low SES and any VI remained significant among all age, gender and ethnic sub-groups. Although a consistent positive association was observed between area-level SEDI and any VI, the associations were significant among participants aged 40–65 years and male. Conclusion In this

    Background Public health research is shifting focus to the role of socioeconomic indicators in the promotion of health. As such an understanding of the roles that socio-economic factors play in improving health and health-seeking behaviour is important for public health policy. This is because the share of resources devoted to different policy options should depend on their relative effectiveness. Objective To measure the effect of socio-economic status (age, education, occupation, income, religion and family structure) of mothers on the management of febrile conditions in under-fives children Method Two hundred mothers who brought their febrile under-five children to a health facility were interviewed on the treatment they gave to their children before reporting at health facility. Data collected were entered and analyzed using the SPSS software. Binary logistic regression was adopted for the quantitative analysis of the effect of socio-economic variables on the mothers' actions prior to utilizing the health facility. Results Results showed that while mothers' age was negatively correlated (-0.13), occupation was positively correlated (0.17) with under-fives mothers' action. Education, religion, income and family structure were however insignificant at 5% level Conclusion This poses a lot of challenges to policy makers in the developing nations where women's education and earning capacity is low. There is therefore a need to increase the number of women benefiting from micro credit. This will ensure that more women are engaged in a form of occupation that is profitable and can sustain the economic and health needs of the family. PMID:16426450

    Analysing urban regions is essential for their correct monitoring and planning. This is mainly accounted for the sharp increase of people living in urban areas, and consequently, the need to manage them. At the same time there has been a rise in the use of spatial and statistical datasets, such as the Urban Atlas, which offers high-resolution urban land use maps obtained from satellite imagery, and the Urban Audit, which provides statistics of European cities and their surroundings. In this study, we analyse the relations between urban fragmentation metrics derived from Land Use and Land Cover (LULC) data from the Urban Atlas dataset, and socio-economic data from the Urban Audit for the reference years 2006 and 2012. We conducted the analysis on a sample of sixty-eight Functional Urban Areas (FUAs). One-date and two-date based fragmentation indices were computed for each FUA, land use class and date. Correlation tests and principal component analysis were then applied to select the most representative indices. Finally, multiple regression models were tested to explore the prediction of socio-economic variables, using different combinations of land use metrics as explanatory variables, both at a given date and in a dynamic context. The outcomes show that demography, living conditions, labour, and transportation variables have a clear relation with the morphology of the FUAs. This methodology allows us to compare European FUAs in terms of the spatial distribution of the land use classes, their complexity, and their structural changes, as well as to preview and model different growth patterns and socio-economic indicators.

  15. A bridge between liquids and socio-economic systems: the key role of interaction strengths

    One distinctive and pervasive aspect of social systems is the fact that they involve several kinds of agents. Thus, in order to draw parallels with physical systems one is led to consider binary (or multi-component) compounds. Recent views about the mixing of liquids in solutions gained from neutron and X-ray scattering show these systems to have a number of similarities with socio-economic systems. It appears that such phenomena as rearrangement of bonds in a solution, gas condensation, and selective evaporation of molecules can be transposed in a natural way to some socio-economic phenomena. These connections provide with a novel perspective for looking at social systems which we illustrate through examples. For instance, we interpret suicide as an escape phenomenon and in order to test this interpretation we consider social systems characterized by very low levels of social interaction. For these systems suicide rates are found to be 10 to 100 times higher than in the general population. Another interesting parallel concerns the phase transition that occurs when locusts gather together to form swarms which may contain several billion insects. What hinders the thorough investigation of such cases from the standpoint of collective phenomena that we advocate is the lack or inadequacy of statistical data; up to now socio-economic data were collected for completely different purposes. Most essential, for further progress, are the statistics which would permit to estimate the strength of social ties and interactions. Once adequate data become available, rapid advancement may be expected. At the end of the paper, we will discuss whether or not the ergodic principle applies to social systems.

  16. Socio-economic analysis: a tool for assessing the potential of nanotechnologies

    Cost-Benefit Analysis (CBA) has a long history, especially in the USA, of being used for the assessment of new regulation, new infrastructure and more recently for new technologies. Under the denomination of Socio-Economic Analysis (SEA), this concept is used in EU safety and environmental regulation, especially for the placing of chemicals on the market (REACh regulation) and the operation of industrial installations (Industrial Emissions Directive). As far as REACh and other EU legislation apply specifically to nanomaterials in the future, SEA might become an important assessment tool for nanotechnologies. The most important asset of SEA regarding nanomaterials, is the comparison with alternatives in socio-economic scenarios, which is key for the understanding of how a nanomaterial "socially" performs in comparison with its alternatives. "Industrial economics" methods should be introduced in SEAs to make industry and the regulator share common concepts and visions about economic competitiveness implications of regulating nanotechnologies, SEA and Life Cycle Analysis (LCA) can complement each other : Socio-Economic LCA are increasingly seen as a complete assessment tool for nanotechnologies, but the perspective between Social LCA and SEA are different and the respective merits and limitations of both approaches should be kept in mind. SEA is a "pragmatic regulatory impact analysis", that uses a cost/benefit framework analysis but remains open to other disciplines than economy, and open to the participation of stakeholders for the construction of scenarios of the deployment of technologies and the identification of alternatives. SEA is "pragmatic" in the sense that it is driven by the purpose to assess "what happens" with the introduction of nanotechnology, and uses methodologies such as Life Cycle Analysis only as far as they really contribute to that goal. We think that, being pragmatic, SEA is also adaptative, which is a key quality to handle the novelty of

    San Francisco Bay is the largest estuary on the conterminous U.S. Pacific Coast and is one of the world's largest natural harbors. It is a biologically productive and diverse environment. San Francisco Bay has a maritime economy that annually generates over $7.5 billion, handles 50 million tons of cargo, and involves thousands of jobs. Recent investigations by the USGS in this estuary help address both socio-economic and scientific issues: *Trimming pinnacles may prevent a calamitous oil spill. *Can San Francisco Bay accept more dredge spoil? *Bay floor biological habitats are quite varied. *How thick and how variable is the sediment fill in central San Francisco Bay?

    The prevalence of myofacial pain dysfunction syndrome (MPDS) was investigated in Zimbabwe. The study was carried out at Government dental centres, where most of the patients seen were local indigenous Zimbabweans belonging to the lower and lower middle socio-economic group which forms more than 80 per cent of the population of the country. There was a very low prevalence in this group unlike the results of similar studies in more developed countries. Nervous tensions, stress and strains associated with a faster pace of life and often cited in the aetiology of MPDS could be the attributing factor.

    Adults from South Auckland, New Zealand who required acute admission to hospital were followed from admission to discharge. After adjusting for demographic factors, diagnosis, chronicity, severity, consultant psychiatrist and involuntary admission, the length of stay for those from more deprived areas was significantly longer by 7 days than for those from less deprived areas. Information on socio-economic deprivation should be used in discharge planning and in optimising access to community care. Research is needed on group-level factors that may affect recovery from mental disorders.

    The recent tobacco excise tax increase and economic crisis reduced cigarette affordability in Ukraine dramatically. Using survey data from Stakhanov (n = 1691), eastern Ukraine, we employed logistic regression analysis to examine whether socio-economic status was associated with the continuation of smoking in this environment in 2009. Low education (in women) and ownership of household assets (in men) were negatively associated with smoking continuation, whereas a positive association was found for personal monthly income. Our findings suggest that in a low-income setting where efficient cessation services are absent, reduced cigarette affordability may have only a limited effect in cutting down smoking.

  2. The socio-economic distribution of health-related occupational stressors among wage-earners in a Post-Fordist labour market

    2010-01-01

    Unequal exposure to occupational stressors is a central pathway towards socio-economic health inequalities in working populations. This paper assesses the differential exposure of such stressors within the population of Flemish wage-earners. Our focus is on differences in gender, age, skill levels, occupational and social class positions. Method The analyses are based on the "Flemish Quality of Labour Monitor 2004" (Vlaamse Werkbaarheidsmonitor 2004), a cross-sectional representative sample (N = 11,099) of 16- to 65-year-old wage-earners, living in Flanders. The investigated health-related working conditions are: high quantitative, emotional and physical demands, frequent repetitive movements, atypical work schedules, frequent overtime work and schedule changes, low job autonomy, task variation and superior-support, high job insecurity and exposure to bullying. The distribution of the working conditions is assessed by means of standard logistic regression analyses. Also gender specific analyses are performed. Results At least two clusters of health-related occupational stressors can be identified. On the one hand, high physical demands, atypical schedules, low control over the work environment and high job insecurity are more common in manual, unskilled and subordinate workers. On the other hand, high quantitative and emotional demands, as well as schedule unpredictability are characteristic of higher skilled, professional and managerial employees. Conclusion Since little empirical information on the socio-economic distribution of various health-related occupational stressors is available for Flanders, our results are important for obtaining more insight into the pathways linking occupational health risks to socio-economic health inequalities in the Flemish wage-earning population.

    Background: Socioeconomic inequalities in obesity are well established in high-income countries. There is a lack of evidence of the types of intervention that are effective in reducing these inequalities among adults. Objectives: To systematically review studies of the effectiveness of individual, community and societal interventions in reducing socio-economic inequalities in obesity among adults. Methods: Nine electronic databases were searched from start date to October 2012 along with website and grey literature searches. The review examined the best available international evidence (both experimental and observational) of interventions at an individual, community and societal level that might reduce inequalities in obesity among adults (aged 18 years or over) in any setting and country. Studies were included if they reported a body fatness-related outcome and if they included a measure of socio-economic status. Data extraction and quality appraisal were conducted using established mechanisms and narrative synthesis was conducted. Results: The ‘best available' international evidence was provided by 20 studies. At the individual level, there was evidence of the effectiveness of primary care delivered tailored weight loss programmes among deprived groups. Community based behavioural weight loss interventions and community diet clubs (including workplace ones) also had some evidence of effectiveness—at least in the short term. Societal level evaluations were few, low quality and inconclusive. Further, there was little evidence of long term effectiveness, and few studies of men or outside the USA. However, there was no evidence to suggest that interventions increase inequalities. Conclusions: The best available international evidence suggests that some individual and community-based interventions may be effective in reducing socio-economic inequalities in obesity among adults in the short term. Further research is required particularly of more complex, multi

    Two samples, male college students and convicted male child sex offenders, are compared on their abilities to accurately estimate the age group of a series of photographs of a sole female ranging in age from 11 to 29. Both samples tend to overestimate the age group of the subject photos, and no significant difference was found between college students and convicted child sex offenders in their ability to estimate the age of females. Both groups are compared demographically, and only limited differences were found. The implications are discussed in regard to theory and prevention of child sexual abuse.

    A dietary survey was carried out in 216 children (109 males, 107 females) aged 1-7 years, living in rural villages in Selangor, Malaysia to assess their nutrient intake and to determine the association between nutrient consumption and socio-economic background. All the children studied had inadequate intakes of energy, iron and niacin according to Recommended Daily Intake (RDI). Children aged of 4-9 years showed inadequate intake of calcium, thiamine and riboflavin. However, the intake of protein, vitamin A and ascorbic acid were above the recommended value. The mean percentage requirements of protein, iron and niacin were significantly higher in children from small families compared with children from large families. However the employment status of mothers had a significantly effect on the mean percentage requirements of niacin. The results indicate that education level of the mothers, is strongly associated with the mean percentage nutrient requirements of children and we strongly feel that this is a strategy to be adopted for improvement in nutrition of children.

    Background Dementia is a major public health challenge and China has the largest population with dementia in the world. However, dementia care and caregivers for Chinese are less investigated. Objectives and design To evaluate demographic and socio-economic influences on dementia care, management patterns and caregiver burden in a household community-dwelling-based survey, using participants’ care receipts and Zarit scale. Setting and participants Rural and urban communities across six provinces of China comprising 4837 residents aged ≥60 years, in whom 398 had dementia and 1312 non-dementia diseases. Results People with dementia were less likely to receive care if they were living in rural compared to urban areas (Odd ratio (OR) = 0.20; 95%CI: 0.10–0.41), having education level below compared to above secondary school (OR = 0.24; 95%CI: 0.08–0.70), manual labourer compared to non-manual workers (OR = 0.27; 95%CI: 0.13–0.55), having personal annual income below RMB 10,000 yuan (£1000) compared to above (OR = 0.37; 95%CI: 0.13–0.74) or having four or more than compared to less four children (OR = 0.52; 95%CI: 0.27–1.00). Caregivers for dementia compared with those for non-dementia diseases were younger and more likely to be patients’ children or children in-law, had lower education and spent more caring time. Caregiver burden increased with low education, cutback on work and caring for patients who were younger or living in rural areas, and this caregiver burden was three-fold greater than that for non-dementia diseases. Conclusions There are a number of inequalities in dementia care and caregiver burden in China. Reducing the socio-economic gap and increasing education may improve community care for people with dementia and preserve caregivers’ well-being. PMID:27478589

    Dogs play an important role in infectious disease transmission as reservoir hosts of many zoonotic and wildlife pathogens. Nevertheless, unlike wildlife species involved in the life cycle of pathogens, whose health status might be a direct reflection of their fitness and competitive abilities, dog health condition could be sensitive to socio-economic factors impacting the well-being of their owners. Here, we compare several dog health indicators in three rural communities of Panama with different degrees of socio-economic deprivation. From a total of 78 individuals, we collected blood and fecal samples, and assessed their body condition. With the blood samples, we performed routine hematologic evaluation (complete blood counts) and measured cytokine levels (Interferon-γ and Interleukin-10) through enzyme-linked immunosorbent assays. With the fecal samples we diagnosed helminthiases. Dogs were also serologically tested for exposure to Trypanosoma cruzi and canine distemper virus, and molecular tests were done to assess T. cruzi infection status. We found significant differences between dog health measurements, pathogen prevalence, parasite richness, and economic status of the human communities where the dogs lived. We found dogs that were less healthy, more likely to be infected with zoonotic pathogens, and more likely to be seropositive to canine distemper virus in the communities with lower economic status. This study concludes that isolated communities of lower economic status in Panama may have less healthy dogs that could become major reservoirs in the transmission of diseases to humans and sympatric wildlife.

    The advent of publishing anonymized call detail records opens the door for temporal and spatial human dynamics studies. Such studies, besides being useful for creating universal models for mobility patterns, could be also used for creating new socio-economic proxy indicators that will not rely only on the local or state institutions. In this paper, from the frequency of calls at different times of the day, in different small regional units (sub-prefectures) in Côte d'Ivoire, we infer users' home and work sub-prefectures. This division of users enables us to analyze different mobility and calling patterns for the different regions. We then compare how those patterns correlate to the data from other sources, such as: news for particular events in the given period, census data, economic activity, poverty index, power plants and energy grid data. Our results show high correlation in many of the cases revealing the diversity of socio-economic insights that can be inferred using only mobile phone call data. The methods and the results may be particularly relevant to policy-makers engaged in poverty reduction initiatives as they can provide an affordable tool in the context of resource-constrained developing economies, such as Côte d'Ivoire's.

    The objective of the research addressed in this paper is to identify and analyze the offsite effects of DOE activities at the Savannah River Site. The paper presents the socio-economic conditions of the areas surrounding the site in order to evaluate the possible effects of DOE activities. The study employed a geographic information system (GIS) in order to evaluate spatial relationships between otherwise unrelated factors. Socio-economic data used in the study are publicly available and were obtained mainly from the Bureau of the Census. The Department of Energy (DOE), currently dealing with the environmental management of a large number of sites throughout the United States, must consider the effects of its activities on surrounding populations and ensure compliance with the various federal regulations, such as the executive order on environmental justice. Environmental justice is the process of studying and achieving equal distribution of the effects of environmental pollution on populations across social and economic lines. An executive order signed by the President has directed federal agencies, including the Department of Energy, to make achieving environmental justice a part of the agency`s mission by identifying and addressing disproportionately high and adverse human health or environmental effects of its programs, policies, and activities on minority and low-income populations.

  10. Future Discounting in Congo Basin Hunter-Gatherers Declines with Socio-Economic Transitions.

    Humans have a tendency to discount the future; that is we value small, short-term rewards over larger, long-term rewards. The degree of future discounting, however, changes in response to socio-ecological factors. Here, we study Mbendjele BaYaka hunter-gatherers of northern Congo and their farmer neighbours to investigate adaptations in inter-temporal preferences in humans. We argue that in immediate-return systems, where food storage is absent and egalitarianism is enforced through levelling mechanisms, future discounting is an adaptive strategy to prevent wealth accumulation and the emergence of hierarchies. This ensures food sharing and allows for survival in unpredictable environments where there is risk of an energy shortfall. On the other hand, when food storage is made possible by the emergence of agriculture or as seen in some delayed-return hunter-gatherer populations, wealth accumulation, hierarchies and lower discount rates become the adaptive strategy. Therefore, individuals in immediate-return, egalitarian societies will discount the future more than those in non-egalitarian, delayed-return societies. Consistent with the predictions we found that market integration and socio-economic transitions decrease the future discounting in Mbendjele hunter-gatherers. Our measures of socio-economic differences marked this transition in hunter-gatherers living in a logging town. The degree of future-discounting was the same between more market-integrated hunter-gatherers and their farmer neighbours.

    Higher levels of nearby traffic increase exposure to air pollution and adversely affect health outcomes. Populations with lower socio-economic status (SES) are particularly vulnerable to stressors like air pollution. We investigated cumulative exposures and risks from traffic and from MNRiskS-modeled air pollution in multiple source categories across demographic groups. Exposures and risks, especially from on-road sources, were higher than the mean for minorities and low SES populations and lower than the mean for white and high SES populations. Owning multiple vehicles and driving alone were linked to lower household exposures and risks. Those not owning a vehicle and walking or using transit had higher household exposures and risks. These results confirm for our study location that populations on the lower end of the socio-economic spectrum and minorities are disproportionately exposed to traffic and air pollution and at higher risk for adverse health outcomes. A major source of disparities appears to be the transportation infrastructure. Those outside the urban core had lower risks but drove more, while those living nearer the urban core tended to drive less but had higher exposures and risks from on-road sources. We suggest policy considerations for addressing these inequities.

    Area-based socio-economic status (SES) measures are frequently used in epidemiology. Such an approach assumes socio-economic homogeneity within an area. To quantify the agreement between area-based SES measures and SES assessed at the individual level, we conducted a cross-sectional study of 943 children who resided in 155 small enumeration areas and 117 census tracts from 18 schools in Montreal, Quebec. We used street address information together with 1986 census data and parental occupation to establish area-based and individual level SES indicators, respectively. As compared with the SES score determined at the level of the individual, 13 different area-based SES indices classified the children within the same quintile 28.7% (+/- 2.8%) of the time. The discrepancy was within one quintile in 35.3% (+/- 2.3%) of cases, two quintiles in 20.6% (+/- 3.6%), three quintiles in 11.3% (+/- 4.2%) and four quintiles in 4.1% (+/- 0.2%). In conclusion, we observed a substantial discrepancy between area- based SES measures and SES assessed at the individual level. Caution should therefore be used in designing or interpreting the results of studies in which area-based SES measures are used to test hypotheses or control for confounding.

    2016-02-01

    In 2013, around 1336 desalination plants in the United States (US) provided purified water mainly to municipalities, the industry sector and for power generation. In 2013 alone, ∼200 million m(3) of water were desalinated; the amount that could satisfy annual municipal water consumption of more than 1.5 million people in the US. Desalination has proven to be a reliable water supply source in many countries around the world, with the total global desalination capacity of ∼60 million m(3)/day in 2013. Desalination has been used to mitigate water scarcity and lessen the pressure on water resources. Currently, data and information about desalination are still limited, while extensive socio-economic analyses are missing. This paper presents an econometric model to fill this gap. It evaluates the impact of selected socio-economic variables on desalination development in the US in the time span 1970-2013. The results show that the GDP and population growth have significantly impacted the desalination sector over the analyzed time period. The insights into the economics of desalination provided with this paper can be used to further evaluate cost-effectiveness of desalination both in the US and in other countries around the world.

    River floods generate a large share of the socio-economic impact of weather-driven hazards worldwide. Accurate assessment of their impact is a key priority for governments, international organization, reinsurance companies and emergency responders. Yet, available databases of flood losses over large domains are often affected by gaps and inconsistencies in reported figures. In this work, a framework to reconstruct the economic damage and population affected by river floods at continental scale is applied. Pan-European river flow simulations are coupled with a high-resolution impact assessment framework based on 2-D inundation modelling. Two complementary methods are compared in their ability to estimate the climatological average flood impact and the impact of each flood event in Europe between 1990 and 2013. The event-based method reveals key features, such as the ability to include changes in time of all three components of risk, namely hazard, exposure and vulnerability. Furthermore, it skilfully reproduces the socio-economic impact of major flood events in the past two decades, including the severe flooding hitting central Europe in June 2013. On the other hand, the integral method is capable of reproducing the average flood losses which occurred in Europe between 1998 and 2009. Strengths and limitations of the proposed model are discussed to stress the large potential for filling in the gaps of current datasets of flood impact.

    Despite the large literature on public health, few studies have examined the associations between public health outcomes and environmental and socio-economic factors. This study bridges this gap by demonstrating the relationships between public health and 10 selected environmental and socio-economic factors from the spatial perspective. In particular, three public health outcomes in China are investigated, namely the number of centenarians per 100,000 people (termed the centenarian ratio), the proportion of nonagenarians of the 65 years and older population (termed the longevity index), and life expectancy at birth. We base our analysis on stepwise regression and geographically weighted regression models, with study areas of 31 provinces in China. Our results show that SO2 (sulfur dioxide) concentration decreases the centenarian ratio; PM10 (particles with diameters of 10 μm or less) concentration and coal consumption (CC) per capita decrease the longevity index, and GDP (Gross Domestic Product) per capita prolongs life expectancy at birth, while energy consumption (EC) per capita decreases life expectancy at birth. Further, our findings demonstrate that public health outcomes show clear regional differences in China.

    The advent of publishing anonymized call detail records opens the door for temporal and spatial human dynamics studies. Such studies, besides being useful for creating universal models for mobility patterns, could be also used for creating new socio-economic proxy indicators that will not rely only on the local or state institutions. In this paper, from the frequency of calls at different times of the day, in different small regional units (sub-prefectures) in Côte d'Ivoire, we infer users' home and work sub-prefectures. This division of users enables us to analyze different mobility and calling patterns for the different regions. We then compare how those patterns correlate to the data from other sources, such as: news for particular events in the given period, census data, economic activity, poverty index, power plants and energy grid data. Our results show high correlation in many of the cases revealing the diversity of socio-economic insights that can be inferred using only mobile phone call data. The methods and the results may be particularly relevant to policy-makers engaged in poverty reduction initiatives as they can provide an affordable tool in the context of resource-constrained developing economies, such as Côte d'Ivoire's.

    Due to an increase in the volume of geohazards worldwide, not only are impoverished regions in less developed countries such as Haiti, vulnerable to risk but also low income regions in industrialized countries, e.g. USA, as well. This has been exemplified once again by Hurricanes Gustav, Hanna and Ike and the impact on the Caribbean countries during the summer of 2008. To date, extensive research has been conducted to improve the monitoring of human-nature coupled systems. However, there is little emphasis on improving and developing methodologies to a) interpret multi-dimensional and complex data and b) validate prediction and modeling results. This presentation tries to motivate more research initiatives to address the aforementioned issues, bringing together two academic disciplines, earth and social sciences, to research the relationship between natural and socio-economic processes. Results are presented where cyber-enabled methods based on artificial intelligence are applied to different geohazards and regions in the world. They include 1) modeling of public health risks associated with volcanic gas hazards, 2) prediction and validation of potential areas of mining-triggered earthquakes, and 3) modeling of socio-economic risks associated with tropical storms in Haiti and the Dominican Republic.

    Semi-arid regions are facing the challenge of managing water resources under conditions of increasing scarcity and drought. These are recently pressured by the impact of climate change favoring the shifting from using surface water to groundwater without taking sustainability issues into account. Likewise, water scarcity raises the competition for water among users, increasing the risk of social conflicts, as the availability of fresh water in sufficient quality and quantity is already one of the major factors limiting socio-economic development. In terms of hydrology, semi-arid regions are characterized by very complex hydro- and hydrogeological systems. The complexity of the water cycle contrasts strongly with the poor data availability, (1) which limits the number of analysis techniques and methods available to researchers, (2) limits the accuracy of models and predictions, and (3) consequently challenges the capabilities to develop appropriate management measures to mitigate or adapt the environment to scarcity and drought conditions. Integrated water resources management is a holistic approach to focus on both environmental as well as on socio-economic factors influencing water availability and supply. The management approaches and solutions adopted, e.g. in form of decision support for specific water resources systems, are often highly specific for individual case studies.

    AIM: To examine if dietary and socio-economic factors contribute to Helicobacter pylori (H pylori) re-infection. METHODS: The population of patients consisted of subjects in whom H pylori infection had been successfully treated in the past. Patients were divided into two groups: I-examined group (111 persons with H pylori re-infection) and II-control group (175 persons who had not been re-infected). The respondents were interviewed retrospectively on their dietary habits and socio-economic factors. RESULTS: A statistically significant lower frequency of fermented dairy products (P < 0.0001), vegetables (P = 0.02), and fruit (P = 0.008) consumption was noted among patients with H pylori re-infection as compared to those who had not been re-infected. CONCLUSION: High dietary intake of probiotic bacteria, mainly Lactobacillus, and antioxidants, mainly vitamin C (contained in fruit and vegetables), might decrease the risk of H pylori re-infection.

    Acacia senegal (locally: Hashab tree) is one of the most important tree species in Sudan as it considers the main Gum Arabic producing tree. The objective of this study is to investigate the socio-economic aspects of gum Arabic production and to assess contribution of gum Arabic to sustainable livelihood of local people in Dalanj Locality, South Kordofan State-Sudan. Social survey was carried out by using structured questionnaire for 80 respondents (gum producers) on random sample basis in eight villages, 10 respondents from each village. Issues pertaining to socio-economic factors affecting gum Arabic production and contribution of gum Arabic to sustainable livelihood of local people, in Dalanj Locality, were assessed. Results of the study revealed that expansion of agriculture lands at the expense of hashab trees, fires and illegal felling are the most important factors constraining gum production in the area. The results also indicated that agriculture is the main source of income and gum Arabic is a supplementary source of income. The importance of gum Arabic becomes apparent during (off farm season) the period between crops harvest and the preparation of the next agricultural season. Establishment of producers' associations and provision of loans to producers are highly recommended to ensure sustainability of gum production.

    Background There are few population-based studies from low- and middle-income countries that have described the association of socio-economic, gender and health factors with common mental disorders (CMDs) in rural women. Methods Population-based study of currently married rural women in the age group of 15–39 years. The baseline data are from the National Family Health Survey-II conducted in 1998. A follow-up study was conducted 4 years later in 2002–03. The outcome of CMD was assessed using the 12-item General Health Questionnaire (GHQ-12). Due to the hierarchical nature and complex survey design, data were analysed using mixed-effect logistic regression with random intercept model. Results A total of 5703 women (representing 83.5% of eligible women) completed follow-up. The outcome of CMD was observed in 609 women (10.7%, 95% confidence interval 9.8–11.6). The following factors were independently associated with the outcome of CMD in the final multivariable model: higher age, low education, low standard of living, recent intimate partner violence (IPV), husband’s unsatisfactory reaction to dowry, husband’s alcohol use and women’s own tobacco use. Conclusions Socio-economic and gender disadvantage factors are independently associated with CMDs in this population of women. Strategies that address structural determinants, for example to promote women’s education and reduce their exposure to IPV, may reduce the burden of CMDs in women. PMID:21037247

    Sex and age differences are particularly pronounced in car accidents. Current psychological research is exploring the relationship between risky driving and compliance with sex stereotypes, notably conformity with social expectations concerning masculinity. Some studies have already shown that sex stereotypes associated with driving (SSAD) may influence driving behaviors. The aim of this research was to explore the participants' sex and age differences in SSAD endorsement. A questionnaire was developed and validated on four dimensions of SSAD: male's driving skills and female's compliance with traffic rules, courtesy behind the wheel, and risk avoidance in driving. SSAD endorsement was measured for 291 licensed drivers from 18 to 64 years of age. Results revealed that females endorsed the female's risk avoidance stereotype more (p < .05), whereas males endorsed the male drivers (driving skills) stereotype more (p < .05). Results also revealed that the endorsement of male's driving skills decreases with age (p < .01) and the endorsement of female's courtesy increases with age among all participants (p = .01), while the endorsement of female's compliance with traffic rules increases with age only among female participants (p < .05). The results are discussed in terms of in-group/out-group relations and sex and age differences.

    Most recent studies of marriage patterns in China have emphasized the male-biased sex ratio but have largely neglected age structure as a factor in China's male marriage squeeze. In this paper we develop an index we call "spousal sex ratio" (SSR) to measure the marriage squeeze, and a method of decomposing the proportion of male surplus into age and sex structure effects within a small spousal age difference interval. We project that China's marriage market will be confronted with a relatively severe male squeeze. For the decomposition of the cohort aged 30, from 2010 to 2020 age structure will be dominant, while from 2020 through 2034 the contribution of age structure will gradually decrease and that of sex structure will increase. From then on, sex structure will be dominant. The index and decomposition, concentrated on a specific female birth cohort, can distinguish spousal competition for single cohorts which may be covered by a summary index for the whole marriage market; these can also be used for consecutive cohorts to reflect the situation of the whole marriage market.

    Exposure to diverse cultures and higher socio-economic status (SES) may increase knowledge of a wide variety of stimuli, including food, and be negatively associated with food neophobia. We contrasted questionnaire responses from two groups of Australian high school students (aged 12-18 years) from remote rural (rural, n=243) and cosmopolitan urban (city, n=696) locations to the food neophobia scale (FNS), familiarity with certain foods and willingness to try those foods. Cultural diversity measures and two SES scales were created. City students were less food neophobic than rural students (mean FNS scores 29.35 versus 34.68, p<0.001). City students were also significantly more familiar with different foods and more willing to try unfamiliar foods, were of higher SES and had greater exposure to cultural diversity. However, the association between the FNS and familiarity with foods, willingness to try unfamiliar foods, SES, and exposure to cultural diversity, were only weak or moderate for both city and rural students. Greater exposure to cultural diversity and higher SES has some influence on adolescents' responses to unfamiliar foods, but the relationship between these factors and the FNS score is tenuous.

    Water, sanitation, and hygiene (WaSH) in schools contributes to better health and educational outcomes among school-aged children. In 2012, UNICEF Nicaragua and partners conducted a cross-sectional survey of WaSH in 526 schools in 12 low socio-economic status municipalities in Nicaragua. The survey gathered information on: school characteristics; teacher and community participation; water and sanitation infrastructure; and hygiene education and habits. Survey results were analyzed for associations between variables. WaSH coverage was significantly higher in urban than rural areas. Presence of drinking water infrastructure (43%) was lower than sanitation infrastructure (64%). Eighty-one percent of schools had no hand washing stations and 74% of schools lacked soap. Sanitation facilities were not in use at 28% of schools with sanitation infrastructure and 26% of schools with water infrastructure had non-functional systems. Only 8% of schools had budgets to purchase toilet-cleaning supplies and 75% obtained supplies from students’ families. This study generates transferable WaSH sector learnings and new insights from monitoring data. Results can be used by donors, service providers, and policy makers to better target resources in Nicaraguan schools. PMID:26035665

    We examined the effects of single-parent family status and high parental socio-economic status (SES) on the trajectories of children's emotional/behavioural adjustment in early-to-middle childhood (ages 3-7 years). We also assessed whether these family characteristics interact with the equivalent neighbourhood characteristics of shares of single-parent families and high-SES adults in predicting these trajectories. Using data on 9850 children in England participating in the Millennium Cohort Study, we found that family status and parental SES predicted children's trajectories of adjustment. Even after controlling for these family factors and key child and parent characteristics, the neighbourhood shares of high-SES adults and single-parent families were related (negatively and positively, respectively) to child problem behaviour. Importantly, children of low-SES parents in neighbourhoods with a high concentration of high-SES adults had fewer emotional symptoms than their counterparts in areas with fewer high-SES adults. Surprisingly, the adverse effect of single-parent family status on child hyperactivity was attenuated in areas with a higher share of single-parent families.

    Studies that investigated the association between socio-economic position (SEP) and obesity in children suggest inconsistent results. The aim of this study is to summarize and quantify the current evidence on SEP and risks of overweight and obesity in children aged 0-15 years. Relevant studies published between 1990 to Sep 4, 2014 were searched in Medline, Web of Science, Embase, and the Cochrane Database of Systematic Reviews. Risk estimates from individual studies were pooled using random-effects models, according to lowest vs the highest SEP category. A total of 62 articles were included in the meta-analysis. The odds of both overweight risk and obesity risk were higher in the children with lowest SEP than in those with highest SEP (OR, 1.10, 95% CI: 1.03-1.17, and OR, 1.41, 95% CI: 1.29-1.55, respectively). Sub-group analyses showed that the inverse relationships between SEP and childhood overweight and obesity were only found in high-income countries and in more economic developed areas. In conclusion, our study suggests that children with lower SEP had higher risks of overweight and obesity, and the increased risks were independent of the income levels of countries.

    During the past few decades, people have been increasingly exposed to health-related messages in the mass media, conveying recommendations for healthy lifestyles. The present study investigates whether these messages represent a stressor, and whether coping responses increase levels of motivation or levels of negative affect. A sample of 403 women aged 45 years were surveyed twice, at an interval of 4 weeks. A substantial proportion of the participants perceived the health messages to be stressful (increased levels of threat). Overall, the participants reported a greater use of adaptive than non-adaptive coping when exposed to the health messages. Socio-economic status (defined in educational terms) was negatively correlated with non-adaptive coping, while health consciousness was positively correlated with adaptive coping. Adaptive coping was positively related, and non-adaptive coping was negatively related, to intentions and behaviours. Non-adaptive coping was associated with stronger negative emotions. The results indicate that less-educated women tend to respond more non-adaptively to health messages than more-educated women; for the former group, this has negative consequences in terms of increased levels of negative emotions and decreased levels of motivation to engage in healthy behaviours.

    South Asian (SA) children are less active but have enhanced metabolic risk factors. Physical activity (PA) is a modifiable risk factor for metabolic disease. Evidence suggests that environmental factors and socio-economic status influence PA behaviour. The purpose of this study was to understand PA environments, barriers and facilitators of PA in deprived environments for children from SA backgrounds. Focus groups were conducted with 5 groups of children aged 7-9 years (n = 33; male = 16, female = 17; SA = 17, White = 8 and Black = 8) from two schools in deprived wards of Coventry, England. Thematic analysis was used to identify key themes and subthemes across all transcripts. From the results, emergent themes included school and home environment, outdoor activity, equipment, weather, parental constraints and safety. Ethnic differences were apparent for sources of beliefs and knowledge and religious practice as constraints for PA. The findings suggest that school provides a good foundation for PA attitude, knowledge and behaviour, especially for SA children. To increase PA, multi-component interventions are needed, which focus on changing the home environment (i.e. junk food and media time), encouraging outdoors activity, changing perceptions of safety and weather conditions, which provide parental constraints for children. Interventions also need to be considerate to religious practices that might constrain time.

    There are considerable cross-national differences in public attitudes towards antibiotics use, use of prescribed antibiotics, and self-medication with antibiotics even within Europe. This study was aimed at investigating the relationships between socio-economic factors, cultural values, national personality characteristics and the antibiotic use in Europe. Data included scores from 27 European countries (14 countries for personality analysis). Correlations between socio-economic variables (Gross National Income per capita, governance quality, life expectancy, mean years of schooling, number of physicians), Hofstede's cultural value dimensions (power distance, individualism, masculinity, uncertainty avoidance, long-term orientation, indulgence), national personality characteristic (extraversion, neuroticism, social desirability) and antibiotic use were calculated and three regression models were constructed. Governance quality (r=-.51), mean years of schooling (r=-.61), power distance (r=.59), masculinity (r=.53), and neuroticism (r=.73) correlated with antibiotic use. The highest amount of variance in antibiotic use was accounted by the cultural values (65%) followed by socio-economic factors (63%) and personality factors (55%). Results show that socio-economic factors, cultural values and national personality characteristics explain cross-national differences in antibiotic use in Europe. In particular, governance quality, uncertainty avoidance, masculinity and neuroticism were important factors explaining antibiotics use. The findings underline the importance of socio-economic and cultural context in health care and in planning public health interventions.

    Assessment of socio-economic issues of fishing community is an important aspect in framing a strategy for the preservation of eco-systems which leads to sustainable lagoon management. The present investigation analyses the current potential socio-economic status of the fishing community of Pulicat lagoon, the second largest lagoon in India. The socio-economic indicators considered in the study include demography, economic aspects, social aspects and occupation details. The relevant details were collected from 300 fisher folk family by conducting field survey through a well prepared questionnaire in the villages around Pulicat lagoon. The data analysis was done using Statistical Program for Social Sciences (SPSS) to assess the adequacy and precision of the collected data. The important and encouraging socio-economic indicators identified from the field survey for effective lagoon management includes significant presence of younger generation in the region; affinity and self-belongingness of fisher folk towards the lake; better economic status and moderate education level; appreciable fishing income and affinity towards fishing profession. It is emphasized to motivate the fisher folk to improve their work attitude for betterment in economic status. The pertinent lagoon issues, comprising seasonal variation, local fishing issues, pollution from industries, water intake to thermal power plant which directly or indirectly affects the socio-economic status of fishing community, also need much emphasis while proposing sustainable lagoon management system. The information and observation from this study will be very helpful in formulating management policies on the conservation of the Pulicat lagoon ecosystem.

  18. Strong or Weak Handgrip? Normative Reference Values for the German Population across the Life Course Stratified by Sex, Age, and Body Height

    Handgrip strength is an important biomarker of healthy ageing and a powerful predictor of future morbidity and mortality both in younger and older populations. Therefore, the measurement of handgrip strength is increasingly used as a simple but efficient screening tool for health vulnerability. This study presents normative reference values for handgrip strength in Germany for use in research and clinical practice. It is the first study to provide normative data across the life course that is stratified by sex, age, and body height. The study used a nationally representative sample of test participants ages 17–90. It was based on pooled data from five waves of the German Socio-Economic Panel (2006–2014) and involved a total of 11,790 persons living in Germany (providing 25,285 observations). Handgrip strength was measured with a Smedley dynamometer. Results showed that peak mean values of handgrip strength are reached in men’s and women’s 30s and 40s after which handgrip strength declines in linear fashion with age. Following published recommendations, the study used a cut-off at 2 SD below the sex-specific peak mean value across the life course to define a ‘weak grip’. Less than 10% of women and men aged 65–69 were classified as weak according to this definition, shares increasing to about half of the population aged 80–90. Based on survival analysis that linked handgrip strength to a relevant outcome, however, a ‘critically weak grip’ that warrants further examination was estimated to commence already at 1 SD below the group-specific mean value.

    Handgrip strength is an important biomarker of healthy ageing and a powerful predictor of future morbidity and mortality both in younger and older populations. Therefore, the measurement of handgrip strength is increasingly used as a simple but efficient screening tool for health vulnerability. This study presents normative reference values for handgrip strength in Germany for use in research and clinical practice. It is the first study to provide normative data across the life course that is stratified by sex, age, and body height. The study used a nationally representative sample of test participants ages 17-90. It was based on pooled data from five waves of the German Socio-Economic Panel (2006-2014) and involved a total of 11,790 persons living in Germany (providing 25,285 observations). Handgrip strength was measured with a Smedley dynamometer. Results showed that peak mean values of handgrip strength are reached in men's and women's 30s and 40s after which handgrip strength declines in linear fashion with age. Following published recommendations, the study used a cut-off at 2 SD below the sex-specific peak mean value across the life course to define a 'weak grip'. Less than 10% of women and men aged 65-69 were classified as weak according to this definition, shares increasing to about half of the population aged 80-90. Based on survival analysis that linked handgrip strength to a relevant outcome, however, a 'critically weak grip' that warrants further examination was estimated to commence already at 1 SD below the group-specific mean value.

    Background There is a dearth of information on diet-related chronic diseases in West Africa. This cross-sectional study assessed the rate of obesity and other cardiovascular disease (CVD) risk factors in a random sample of 200 urban adults in Benin and explored the associations between these factors and socio-economic status (SES), urbanisation as well as lifestyle patterns. Methods Anthropometric parameters (height, weight and waist circumference), blood pressure, fasting plasma glucose, and serum lipids (HDL-cholesterol and triglycerides) were measured. WHO cut-offs were used to define CVD risk factors. Food intake and physical activity were assessed with three non-consecutive 24-hour recalls. Information on tobacco use and alcohol consumption was collected using a questionnaire. An overall lifestyle score (OLS) was created based on diet quality, alcohol consumption, smoking, and physical activity. A SES score was computed based on education, main occupation and household amenities (as proxy for income). Results The most prevalent CVD risk factors were overall obesity (18%), abdominal obesity (32%), hypertension (23%), and low HDL-cholesterol (13%). Diabetes and hypertriglyceridemia were uncommon. The prevalence of overall obesity was roughly four times higher in women than in men (28 vs. 8%). After controlling for age and sex, the odds of obesity increased significantly with SES, while a longer exposure to the urban environment was associated with higher odds of hypertension. Of the single lifestyle factors examined, physical activity was the most strongly associated with several CVD risk factors. Logistic regression analyses revealed that the likelihood of obesity and hypertension decreased significantly as the OLS improved, while controlling for potential confounding factors. Conclusion Our data show that obesity and cardio-metabolic risk factors are highly prevalent among urban adults in Benin, which calls for urgent measures to avert the rise of diet

    The "hygiene hypothesis" suggests that a reduction in the exposure to infectious agents due to improved health conditions has contributed to the increased incidence of autoimmune disorders in developed countries. In keeping with the hygiene hypothesis, many autoimmune disorders such as multiple sclerosis (MS) are more frequently observed in developed countries. To identify the relevance of hygiene hypothesis in neuro-Behçet's disease (NBD), another chronic inflammatory disease of the central nervous system, we developed and administered a multiple choice questionnaire to evaluate the hygiene conditions and practices of age and gender-matched NBD patients (n = 50) and control MS (n =5 0) and headache (n = 50) patients. Overall, MS patients had the highest socio-economic and hygiene features, whereas NBD patients displayed a lower socio-economic status group and showed poorer hygiene conditions than MS and headache controls. These poor hygiene conditions might be increasing the susceptibility of exposure to infectious agents that might, at least in part, trigger the inflammatory responses involved in NBD pathogenesis.

  2. Using GIS-based methods of multicriteria analysis to construct socio-economic deprivation indices

    Background Over the past several decades researchers have produced substantial evidence of a social gradient in a variety of health outcomes, rising from systematic differences in income, education, employment conditions, and family dynamics within the population. Social gradients in health are measured using deprivation indices, which are typically constructed from aggregated socio-economic data taken from the national census – a technique which dates back at least until the early 1970's. The primary method of index construction over the last decade has been a Principal Component Analysis. Seldom are the indices constructed from survey-based data sources due to the inherent difficulty in validating the subjectivity of the response scores. We argue that this very subjectivity can uncover spatial distributions of local health outcomes. Moreover, indication of neighbourhood socio-economic status may go underrepresented when weighted without expert opinion. In this paper we propose the use of geographic information science (GIS) for constructing the index. We employ a GIS-based Order Weighted Average (OWA) Multicriteria Analysis (MCA) as a technique to validate deprivation indices that are constructed using more qualitative data sources. Both OWA and traditional MCA are well known and used methodologies in spatial analysis but have had little application in social epidemiology. Results A survey of British Columbia's Medical Health Officers (MHOs) was used to populate the MCA-based index. Seven variables were selected and weighted based on the survey results. OWA variable weights assign both local and global weights to the index variables using a sliding scale, producing a range of variable scenarios. The local weights also provide leverage for controlling the level of uncertainty in the MHO response scores. This is distinct from traditional deprivation indices in that the weighting is simultaneously dictated by the original respondent scores and the value of the

    The combination of degrading natural conditions and resources, climate change, growing population, urban development, and competition in a global market complicate optimization of land for agricultural products. The use of pesticides and fertilizers for crop production in the agricultural fields has become excessive in the recent years and Golestan Province of Iran is no exception in this regard. For this, effective management with an efficient and cost-effective practice should be undertaken, maintaining public service at a high level and preserving the environment. Improving the production efficiency of agriculture, efficient use of water resources, decreasing the use of pesticides and fertilizers, improving farmer revenue, and conservation of natural resources are the main objectives of the allocation, ranking, and optimization of agricultural products. The goal of this paper is to use an optimization procedure to lower the negative effects of agriculture while maintaining a high production rate, which is currently a gap in the study area. We collected information about fertilizer and pesticide consumption and other data in croplands of eastern Golestan Province through face-to-face interviews with farmers to optimize cultivation of the agricultural products. The toxicity of pesticides according to LD50 was also included in the optimization model. A decision-support software system called multiple criteria analysis tool was used to simultaneously minimize consumption of water, chemical fertilizers, and pesticides and maximize socio-economic returns. Three scenarios for optimization of agricultural products were generated that alternatively emphasized on environmental and socio-economic goals. Comparing socio-economic and environmental performance of the optimized agricultural products under the three scenarios illustrated the conflict between social, economic, and environmental objectives. Of the six crops studied (wheat, barley, rice, soybeans, oilseed rape

    Food item use by coyotes was compared between sexes and among age classes at the Naval Petroleum Reserves, California. Item use did not differ significantly between males and females. Although leporid was the item most frequently used by all age classes, item use differed significantly between pups (< 1 year), yearlings (1 year), and adults (> 1 year), probably due to differential use of secondary items. Variation in item use among age classes could potentially bias results of coyote food habit studies.

    This study examines sex differences in the risk threshold for adolescent delinquency. Analyses were based on longitudinal data from the Pittsburgh Youth Study (n = 503) and the Pittsburgh Girls Study (n = 856). The study identified risk factors, promotive factors, and accumulated levels of risks as predictors of delinquency and nondelinquency, respectively. The risk thresholds for boys and girls were established at two developmental stages (late childhood: ages 10–12 years, and adolescence: ages 13–16 years) and compared between boys and girls. Sex similarities as well as differences existed in risk and promotive factors for delinquency. ROC analyses revealed only small sex differences in delinquency thresholds, that varied by age. Accumulative risk level had a linear relationship with boys’ delinquency and a quadratic relationship with girls’ delinquency, indicating stronger effects for girls at higher levels of risk.

    An examination of age and sex or gender (sex/gender) in HIV vaccine preparedness studies can contribute to an understanding of these demographic variables in preparation for actual HIV vaccine trials. In this descriptive review, age and sex or gender (sex/gender) were examined in relation to willingness to participate (WTP) and retention in an HIV vaccine trial. Twenty-five articles were retrieved from the Organization for Economic Co-operation and Development (OECD) countries and 28 articles were retrieved from the non-OECD countries. In US studies that involved mainly white MSM, older men were more likely to be WTP in a hypothetical HIV vaccine trial and more likely to be retained than younger men. In most OECD studies, sex/gender was not associated with WTP in a hypothetical HIV vaccine trial, while females were more likely to be retained in most studies. Largely, age was not associated with WTP in the non-OECD countries, but the results on sex/gender were more variable. The relationship between adolescent or adult WTP in hypothetical HIV vaccine trials in South Africa did not appear to be modified by high school student status. In addition, more studies in discordant couples in the context of HIV vaccine preparedness could be conducted to examine gender roles and inequalities in preparation for HIV vaccine trials.

    We analyse the urban mobility in the cities of Medellín and Manizales (Colombia). Each city is represented by six mobility networks, each one encoding the origin-destination trips performed by a subset of the population corresponding to a particular socio-economic status. The nodes of each network are the different urban locations whereas links account for the existence of a trip between two different areas of the city. We study the main structural properties of these mobility networks by focusing on their spatio-temporal patterns. Our goal is to relate these patterns with the partition into six socio-economic compartments of these two societies. Our results show that spatial and temporal patterns vary across these socio-economic groups. In particular, the two datasets show that as wealth increases the early-morning activity is delayed, the midday peak becomes smoother and the spatial distribution of trips becomes more localized.

    2014-01-01

    We examined the effects of nutritional stress on maternal mortality arising from short-term economic crises in eighteenth-century and nineteenth-century Germany, and how these effects might have been mitigated by socio-economic status. Historical data from six German villages were used to assess how socio-economic conditions and short-term economic crises following poor harvests may have affected maternal mortality. The results show that 1 year after an increase in grain prices the risk of maternal death increased significantly amongst the wives of those working outside the agricultural sector, and more so than for the wives of those working on farms. Nutritional crises seem to have had a significantly stronger impact on maternal mortality in the period 2-6 weeks after childbirth, when mothers were most prone to infections and indirect, obstetrical causes of maternal death. The findings indicate that both nutritional stress and socio-economic factors contributed to maternal mortality.

    In integrative biomedical research, methods assessing the clinical or even socio-economic impact of more complex technologies such as Information and Communication Technology (ICT)-based tools for modelling and simulation of human physiology have rarely been applied. The EU funded Osteoporotic Virtual Physiological Human (VPHOP) research project, part of the Virtual Physiological Human (VPH) European initiative, will create a patient-specific hypermodel to predict the absolute risk of bone fracture much more accurately than predictions based on current clinical practice. The project has developed an innovative, multilevel generic methodological framework to assess the clinical and socio-economic impact of biocomputational models. The assessment framework consists of three components: a socio-economic cost benefit analysis, health economic analysis of care pathways, and disease cost simulation models. Through its holistic perspective, the method provides a tool to appraise the overall value of biocomputational models for society.

    Business has played a central role in the debate over Britain's place in the European Union. This paper examines the socio-economic characteristics of directors of Britain's largest corporations who affiliated either to Business for Sterling or Britain in Europe. It reports associations between directors' social backgrounds and their probabilities of affiliation. Elite university education, club membership, wealth and multiple directorships were all associated with higher propensities to affiliate. The associations are consistent with the idea that directors' social resources allow them to overcome collective action problems as well as supplying them with the motivations to affiliate. They also indicated that directors form a privileged group in that they have a number of very powerful actors who can take unilateral political actions.

    We use a parallelized spatial analytics platform to process the twenty-one year totality of the longest-running time series of night-time lights data—the Defense Meteorological Satellite Program (DMSP) dataset—surpassing the narrower scope of prior studies to assess changes in area lit of countries globally. Doing so allows a retrospective look at the global, long-term relationships between night-time lights and a series of socio-economic indicators. We find the strongest correlations with electricity consumption, CO2 emissions, and GDP, followed by population, CH4 emissions, N2O emissions, poverty (inverse) and F-gas emissions. Relating area lit to electricity consumption shows that while a basic linear model provides a good statistical fit, regional and temporal trends are found to have a significant impact. PMID:28346500

    In this study, flood risks in the present and the end of the 21st century in Asia are estimated using a future socio-economic scenario. Using the runoff data of 7 GCMs (RCP 8.5) of CMIP5, the river discharge, inundation area, and inundation depth are calculated for the assessment of flood risk. Finally, the flood risk is estimated using a function of damage. The flood frequency in the end of the 21st century in Asia tends to increase. Inundation area in Japan, Taiwan, and Kyrgyz is almost unchanged. At the same time, that in Sri Lanka, Bangladesh, Laos, and Myanmar reached about 1.4-1.6 times compared to present. Damage cost is largely influenced by economic growth, however, we show that it is important that we distinguish the influence of climate change from economic development and evaluate it when we think about an adaptation.

    Many industries have long since realised that applying macro-economic analysis methodologies to assess the socio-economic value of a programme is a critical step to convincing decision makers to authorise investment. The geospatial and earth observation industry has however been slow to embrace economic analysis. There are however a growing number of studies, published in the last few years, that have applied economic principles to this domain. They have adopted a variety of different approaches, including: - Computable General Equilibrium Modelling (CGE) - Revealed preference, stated preference (Willingness to Pay surveys) - Partial Analysis - Simulations - Cost-benefit analysis (with and without risk analysis) This paper will critically review these approaches and assess their applicability to different situations and to meet multiple objectives.

    A major paradigm shift with potentially profound implications has been taking place over the past 3 decades at a rapidly accelerating pace. The Copernican revolution of half a millennium ago is now being extended to place humanity on the Earth in its correct cosmic perspective -- an assembly of cosmically derived viral genes, no more, no less, pieced together over 4 billion years of geological history against the processes of Darwinian natural selection. The evidence for our cosmic ancestry has now grown to the point that to deny it is a process fraught with imminent danger. We discuss the weight of modern scientific evidence from diverse sources, the history of development of the relevant ideas, and the socio-economic and historical forces that are responsible for dictating the pace of change.

Interior dwelling characteristics and amenities located within a 2-block radius were similar across the four neighborhood types. However, Houses in urban, working, and lower class neighborhoods reported more alcohol/drug intoxicated persons. Most importantly, despite the greater potential for environmental temptations and easier access for substances, none of the neighborhood factors including neighborhood socio-economic status significantly predicted relapse rates over a 12 month period.

    The influences of sex and age upon endurance performance have previously been documented for both running and swimming. A number of recent studies have investigated how sex and age influence triathlon performance, a sport that combines three disciplines (swimming, cycling and running), with competitions commonly lasting between 2 (short distance: 1.5-km swim, 40-km cycle and 10-km run) and 8 h (Ironman distance: 3.8-km swim,180-km cycle and 42-km run) for elite triathletes. Age and sex influences upon performance have also been investigated for ultra-triathlons, with distances corresponding to several Ironman distances and lasting several days, and for off-road triathlons combining swimming, mountain biking and trail running. Triathlon represents an intriguing alternative model for analysing the effects of age and sex upon endurance and ultra-endurance ([6 h) performance because sex differences and age-related declines in performance can be analysed in the same individuals across the three separate disciplines. The relative participation of both females and masters athletes (age[40 years) in triathlon has increased consistently over the past 25 years. Sex differences in triathlon performance are also known to differ between the modes of locomotion adopted (swimming, cycling or running) for both elite and non-elite triathletes. Generally, time differences between sexes in swimming have been shown to be smaller on average than during cycling and running. Both physiological and morphological factors contribute to explaining these findings. Performance density (i.e. the time difference between the winner and tenth-placed competitor) has progressively improved (time differences have decreased) for international races over the past two decades for both males and females, with performance density now very similar for both sexes. For age-group triathletes, sex differences in total triathlon performance time increases with age. However,the possible difference in age

    Background: Depression is a mental health state whose frequency has been increasing in modern societies. It imposes a great burden, because of the strong impact on people’s quality of life and happiness. Depression can be reliably diagnosed and treated in primary care: if more people could get effective treatments earlier, the costs related to depression would be reversed. The aim of this study was to examine the influence of socio-economic factors and gender on depressed mood, focusing on Korea. In fact, in spite of the great amount of empirical studies carried out for other countries, few epidemiological studies have examined the socio-economic determinants of depression in Korea and they were either limited to samples of employed women or did not control for individual health status. Moreover, as the likely data endogeneity (i.e. the possibility of correlation between the dependent variable and the error term as a result of autocorrelation or simultaneity, such as, in this case, the depressed mood due to health factors that, in turn might be caused by depression), might bias the results, the present study proposes an empirical approach, based on instrumental variables, to deal with this problem. Methods: Data for the year 2008 from the Korea National Health and Nutrition Examination Survey (KNHANES) were employed. About seven thousands of people (N= 6,751, of which 43% were males and 57% females), aged from 19 to 75 years old, were included in the sample considered in the analysis. In order to take into account the possible endogeneity of some explanatory variables, two Instrumental Variables Probit (IVP) regressions were estimated; the variables for which instrumental equations were estimated were related to the participation of women to the workforce and to good health, as reported by people in the sample. Explanatory variables were related to age, gender, family factors (such as the number of family members and marital status) and socio-economic factors

    Estuaries are transitional areas between the land and sea and home to a large and growing proportion of the world's population. They are highly productive ecosystems which create jobs, and boosts local economic growth with a higher percentage of collective and private enterprises and a larger share of production. They serve many important socio-economic functions and therefore receive untreated urban wastes and riverine inputs and concentrate various pollutants coming from inland domestic, agricultural and industrial activities. Therefore such kinds of complex systems are highly vulnerable because they are usually the sink for the hinterlands. Due to serious environmental problems felt more intensively day by day, central and local governments must adopt an integrated policy and decision making process to promote a balance of uses. As surrounded by many historical attractions, heritage sites, buzzing cultural scenes and other natural resources, the Haliç (the Golden Horn estuary) offers great opportunities and has a vitality fed by widespread economic and cultural factors. The typical landscape of the estuary, its bridges, geomorphic features, oceanographic and hydrodynamic features of its waters, sea bottom characteristics, environmental pollution, make this estuary a critical marine environment which impacts to economy, environment and community. However, rapid urban growth and uncontrolled industrial development (1950-1985) led to a severe increase in pollution levels of its water and cohesive sediments. The siltation due to liquid and solid waste dumped by two streams caused anaerobic decomposition problems. In addition, the ecological processes occurring in the Haliç are rather complex as they are interacted with the socio-economic system. This study focuses on the essential elements of integrated coastal zone management for the Haliç, and its probable impacts to economy, environment and community. All objectives and probable impacts need to be integrated

    Strategic thinking and planning have been the hallmarks of Indian space programme, whose objectives are sharply focused on deriving socio-economic benefits of space technology. The purpose of this paper is to identify various strategies, which played a role in different phases of the programme, contributing to social and economic outcomes and effectiveness. While self-reliant development of technological capacity and evaluation of applications with involvement of users formed the backbone of strategy in the initial phase of the programme, subsequent strategies were centred on development of organisational culture and systems, industry role and promotion of spin offs. Other strategies dealt with the response to challenges inherent in space endeavours in terms of risk management, sustainability, investments and long-term commitments, judicious make or buy decisions, safeguard of sensitive technologies, space commerce and finally harmonising international cooperation with national objectives. The strategies in the programme were consistently driven by a clear-cut vision and objectives to develop and use space technology in diverse areas where space systems become relevant for socio-economic development such as telecommunications and broadcasting, meteorology, disaster management support, remote sensing of natural and anthropogenic phenomena, and positioning and navigation services. This paper synthesises various studies and experiences in India in order to analyse strategies in the face of changes in technology, application needs and international policies. It also examines the effectiveness of these strategies in terms of economic and social costs and benefits. Based on the above analysis, a typical conceptual model for use of space for development is suggested.

    Age and sex may influence both efficacy and side effects of second-generation antipsychotics. Women and elderly patients tend to have a higher prevalence for several side effects. Higher plasma levels in these groups of patients may be one reason. We studied the hypothesis that steady-state olanzapine plasma concentrations depend on age and sex. Sixty-seven inpatients on stable olanzapine dose were referred to routine therapeutic drug monitoring of olanzapine. Plasma levels were determined by high-performance liquid chromatography with electrochemical detection. Obtained data were then analyzed by analysis of covariance. Olanzapine plasma levels showed a marked sex difference with significantly higher mean concentrations in female patients (adjusted mean concentrations, 18.5 ng/mL for men and 31.7 ng/mL for women; P = 0.003). On average, the weight-corrected concentration/dose ratios shown by women were 33.5% higher than those shown by men, irrespective of age. Regarding the effect of age, weight-corrected concentration/dose ratios increased by an average of 9.4% per decade of life. All results were adjusted for smoking. Comedication did not significantly influence these results. In conclusion, age and sex are important variables to consider when prescribing olanzapine for women and in the elderly.

    Socio-economic and environmental based vulnerability models have been developed within the research context of the FP6 project BRAHMATWINN. The conceptualisation of vulnerability has been defined in the project and is characterised as a function of sensitivity and adaptive capacity, where sensitivity is used to refer to systems that are susceptible to the impacts of environmental stress. Adaptive capacity is used to refer to systems or resources available to communities that could help them adapt or cope with the adverse consequences of environmental stresses in the recovery phase. In a wider context the approach reflects the wider objective and conceptualizations of the IPCC (Intergovernmental Panel on Climate Change) framework, where vulnerability is characterized as a component of overall risk. A methodology has been developed which delineates spatial units of vulnerability (VULNUS). These units share a specific common characteristic and allow the independent spatial modelling of a complex phenomena independent from administrative units and raster based approaches. An increasing detail of spatial data and complex decision problems require flexible means for scaled spatial representations, for mapping the dynamics and constant changes, and delivering the crucial information. Automated techniques of object-based image analysis (OBIA, Lang & Blaschke, 2006), capable of integrating a virtually unlimited set of spatial data sets, try to match the information extraction with our world view. To account for that, a flexible concept of manageable units is required. The term geon was proposed by Lang (2008) to describe generic spatial objects that are homogenous in terms of a varying spatial phenomena under the influence of, and partly controlled by, policy actions. The geon concept acts as a framework for the regionalization of continuous spatial information according to defined parameters of homogeneity. It is flexible in terms of a certain perception of a problem

    Functional connectivity (FC) in resting-state functional magnetic resonance imaging (rs-fMRI) is widely used to find coactivating regions in the human brain. Despite its widespread use, the effects of sex and age on resting FC are not well characterized, especially during early adulthood. Here we apply regression and graph theoretical analyses to explore the effects of sex and age on FC between the 116 AAL atlas parcellations (a total of 6670 FC measures). rs-fMRI data of 494 healthy subjects (203 males and 291 females; age range: 22-36 years) from the Human Connectome Project were analyzed. We report the following findings. (1) Males exhibited greater FC than females in 1352 FC measures (1025 survived Bonferroni correction; [Formula: see text]). In 641 FC measures, females exhibited greater FC than males but none survived Bonferroni correction. Significant FC differences were mainly present in frontal, parietal, and temporal lobes. Although the average FC values for males and females were significantly different, FC values of males and females exhibited large overlap. (2) Age effects were present only in 29 FC measures and all significant age effects showed higher FC in younger subjects. Age and sex differences of FC remained significant after controlling for cognitive measures. (3) Although sex [Formula: see text] age interaction did not survive multiple comparison correction, FC in females exhibited a faster cross-sectional decline with age. (4) Male brains were more locally clustered in all lobes but the cerebellum; female brains had a higher clustering coefficient at the whole-brain level. Our results indicate that although both male and female brains show small-world network characteristics, male brains were more segregated and female brains were more integrated. Findings of this study further our understanding of FC in early adulthood and provide evidence to support that age and sex should be controlled for in FC studies of young adults.

    Worldwide 10-20 million individuals are living with disabilities after acute poliomyelitis. However, very little is known about the socio-economic consequences and health care costs of poliomyelitis. We carried out a historical register-based study including 3606 individuals hospitalised for poliomyelitis in Copenhagen, Denmark 1940-1954, and 13,795 age and gender-matched Danes. Participants were followed from 1980 until 2012, and family, socio-economic conditions and health care costs were evaluated in different age groups using chi-squared tests, boot-strapped t tests or hazard ratios (HR) calculated in Cox-regression models. The analyses were performed separately for paralytic and non-paralytic polio survivors and their controls, respectively. Compared with controls a higher percentage of paralytic polio survivors remained childless, whereas no difference was observed for non-paralytic polio survivors. The educational level among paralytic as well as non-paralytic polio survivors was higher than that among their controls, employment rate at the ages of 40, 50 and 60 years was slightly lower, whereas total income in the age intervals of 31-40, 41-50 and 51-60 years were similar to controls. Paralytic and non-paralytic polio survivors had a 2.5 [HR = 2.52 (95 % confidence interval (CI); 2.29-2.77)] and 1.4 [HR = 1.35 (95 % CI; 1.23-1.49)]-fold higher risk, respectively, of receiving disability pension compared with controls. Personal health care costs were considerably higher in all age groups in both groups of polio survivors. Individuals with a history of poliomyelitis are well educated, have a slightly lower employment rate, an income similar to controls, but a considerably higher cost in the health care system.

    Background Depression during pregnancy has been demonstrated to be predictive of low birthweight, prematurity, and postpartum depression. These adverse outcomes potentially have lasting effects on maternal and child well-being. Socio-economically disadvantaged women are twice as likely as middle-class women to meet diagnostic criteria for antenatal major depression (MDD), but have proven difficult to engage and retain in treatment. Collaborative care treatment models for depression have not been evaluated for racially/ethnically diverse, pregnant women on Medicaid receiving care in a public health system. This paper describes the design, methodology, culturally relevant enhancements, and implementation of a randomized controlled trial of depression care management compared to public health Maternity Support Services(MSS). Methods Pregnant, public health patients, ≥18 years with a likely diagnosis of MDD or dysthymia, measured respectively by the Patient Health Questionnaire-9(PHQ-9) or the Mini-International Neuropsychiatric Interview(MINI), were randomized to the intervention or to public health MSS. The primary outcome was reduction in depression severity from baseline during pregnancy to 18-months post-baseline(one-year postpartum). Baseline Results 168 women with likely MDD (96.4%) and/or dysthymia (24.4%) were randomized. Average age was 27.6 years and gestational age was 22.4 weeks; 58.3% racial/ethnic minority; 71.4% unmarried; 22% no high school degree/GED; 65.3% unemployed; 42.1% making ≤$10,000 annually; 80.4% having recurrent depression; 64.6% PTSD, and 72% an unplanned pregnancy. Conclusions A collaborative care team, including a psychiatrist, psychologist, project manager, and 3 social workers, met weekly, collaborated with the patients' obstetrics providers, and monitored depression severity using an electronic tracking system. Potential sustainability of the intervention within a public health system requires further study. PMID:25016216

    There was investigated the impact of socioeconomic factors on medical and demographic processes in working age population. For the assessment of the impact of living conditions and environmental factors on mortality rate in a population of the Sverdlovsk region factor-typological, correlation and regression analyzes were applied There was shown an availability of statistically significant correlation relationships between mortality of the population of working age and socio-economic characteristics (degree of home improvement, quality of medical care, the level of social tension, the level of the demographic load), as well as between their increments with taking into account the time shifts. The effect of the value of the purchasing power on the mortality rate of the working population has been established The purchasing power was shown to be connected with a mortality rate of working population from external causes more stronger than death from all causes.

    Objective Given that people who use illicit drugs (PWUD) often engage in prohibited income generation to support their basic needs, we sought to examine the role of these activities in shaping antiretroviral therapy (ART) adherence and plasma HIV RNA-1 viral load suppression among HIV-infected PWUD. Design Longitudinal analyses among HIV-positive, ART exposed PWUD in the AIDS Care Cohort to evaluate Exposure to Survival Services prospective cohort study (2005–2013). Methods Generalized linear mixed effects and mediation analyses examined the relationship between prohibited income generation (e.g. sex work, drug dealing, theft, street-based income) and virologic suppression (plasma viral load ≤ 50 copies/mL plasma) adjusting for adherence and potential confounders. Results Among 687 HIV-infected PWUD, 391 (56.9%) individuals reported prohibited income generation activity during the study period. In multivariate analyses, prohibited income generation remained independently and negatively associated with virologic suppression (adjusted odds ratio: 0.68, 95% confidence interval: 0.52–0.88) following adjustment for hypothesized confounders, including high-intensity drug use, ART adherence and homelessness. While partially mediated by ART adherence, the relationship between prohibited income generation and virologic suppression was maintained in mediation analyses (Sobel statistic = −1.95, p=0.05). Conclusions Involvement in prohibited income generation decreases the likelihood of virologic suppression directly and indirectly through its negative association with ART adherence. These findings suggest that linkages between socio-economic marginalization, the criminalization of illicit drug use and insufficient employment opportunities may produce barriers to access and retention in care. Programmatic and policy interventions that decrease socio-economic vulnerability may therefore reduce HIV-related morbidity, mortality and onward transmission. PMID:26558546

    This study assesses the potential of an integrated methodology for predicting local trends in invasive exotic plant species (invasive richness) using indirect, regional information on human disturbance. The distribution of invasive plants was assessed in North Portugal using herbarium collections and local environmental, geophysical and socio-economic characteristics. Invasive richness response to anthropogenic disturbance was predicted using a dynamic model based on a sequential modeling process (stochastic dynamic methodology-StDM). Derived scenarios showed that invasive richness trends were clearly associated with ongoing socio-economic change. Simulations including scenarios of growing urbanization showed an increase in invasive richness while simulations in municipalities with decreasing populations showed stable or decreasing levels of invasive richness. The model simulations demonstrate the interest and feasibility of using this methodology in disturbance ecology. - Highlights: {yields} Socio-economic data indicate human induced disturbances. {yields} Socio-economic development increase disturbance in ecosystems. {yields} Disturbance promotes opportunities for invasive plants.{yields} Increased opportunities promote richness of invasive plants.{yields} Increase in richness of invasive plants change natural ecosystems.

    Background: This study explored the relationship between socio-economic characteristics at the individual and neighbourhood levels, and wellbeing and lifestyle behaviours of young Iranian women. Methods: Cluster convenience sampling was used to select 391 Iranian women participated in this cross-sectional survey in Shiraz, Iran in 2013. A scale adapted from the British General Household Social Capital questionnaire was used to assess neighbourhood socio-economic characteristics. The satisfaction with life scale, WHO quality of life scale, and the International Health and Behaviours Survey were used to measure wellbeing outcomes and lifestyle behaviours. Results: Findings showed participants were dissatisfied with their neighbourhood socio-economic conditions (M: 36.3±9.8, score range: 11–60) as well as the availability of leisure facilities (M: 1.8, score range: 1–5) in their local areas. Correlations and regression analysis revealed that better neighbourhood socio-economic characteristics were positively associated with better wellbeing outcomes as well as healthier lifestyle behaviours. Conclusion: These findings suggest the need for transitioning economies to be cognisant of the importance of social policy and strategies for enhancing neighbourhood socioeconomic status in order to enhance wellbeing outcomes for sub-populations, including young women.

  1. Age of sex-determining mechanisms in vertebrates.

    PubMed

    WITSCHI, E

    1959-08-14

    Certain characteristic patterns of physiologic sex determination are not causally linked with types of genic and chromosomal constitution (XX-XY or ZW-ZZ). The observed widespread but not universal parallelism in the distribution of genetic and physiologic patterns among vertebrate groups expresses genealogic relationship. On the basis of this interpretation one may estimate the approximate evolutionary age of the mechanism of genetic sex determination. It is concluded that in all tetrapod vertebrates these mechanisms originated during the Jurassic period. Environmental conditions seem to affect the progress of this evolution.

    The MontanAqua project aims to study the water resources management in the region Sierre-Montana (Valais, Switzerland). Land use is known to have an influence on the water resources (soil moisture dynamic, soil sealing, surface runoff and deep percolation). Thus land use modelling is of importance for the water resources management. An actual land use map was produced using infrared imagery (Niklaus 2012, Fig.1). Land use changes are known to be mainly drived by socio-economic factors as well as climatic factors (Dolman et al. 2003). Potential future Land uses was separatly predicted according to 1-. socio-economic and 2-. climatic/abiotic drivers : 1. 4 socio-economic scenarios were developped with stakeholders (Schneider et al. 2013) between 2010 and 2012. We modeled those socio-economic scenarios into a GIS application using Python programming (ModelBuilder in ArcGIS 10) to get a cartographic transcription of the wishes of the stakeholders for their region in 2050. 2. Uncorrelated climatic and abiotic drivers were used in a BIOMOD2 (Georges et al. 2013) framework. 4 models were used: Maximum Entropy (MAXENT), Multiple Adaptive Regression Splines (MARS), Classification Tree Analysis (CTA) and the Flexible Discriminant Analysis (FDA) to predict grassland, alpine pasture, vineyards and forest in our study region. Climatic scenarios were then introduced into the models to predict potential land use in 2050 driven only by climatic and abiotic factors The comparison of all the outputs demonstrates that the socio-economic drivers will have a more important impact in the region than the climatic drivers (e.g. -70% grassland surface for the worst socio-economic scenario vs. -40% of grassland surface for the worst climatic models). Further analysis also brings out the sensitivity of the grassland/alpine pasture system to the climate change and to socio-economic changes. Future work will be to cross the different land use maps obtained by the two model types and to use

    Background Household characteristics are important influences on the risk of child death. However, little is known about this influence in HIV-endemic areas. We describe the effects of household characteristics on children’s risk of dying in rural South Africa. Methods We use data describing the mortality of children younger than 5 years living in the Agincourt health and socio-demographic surveillance system study population in rural northeast South Africa during the period 1994–2008. Using discrete time event history analysis we estimate children’s probability of dying by child characteristics and household composition (other children and adults other than parents) (N = 924 818 child-months), and household socio-economic status (N = 501 732 child-months). Results Children under 24 months of age whose subsequent sibling was born within 11 months experience increased odds of dying (OR 2.5; 95% CI 1.1–5.7). Children also experience increased odds of dying in the period 6 months (OR 2.1; 95% CI 1.2–3.6), 3–5 months (OR 3.0; 95% CI 1.5–5.9), and 2 months (OR 11.8; 95% CI 7.6–18.3) before another household child dies. The odds of dying remain high at the time of another child’s death (OR 11.7; 95% CI 6.3–21.7) and for the 2 months following (OR 4.0; 95% CI 1.9–8.6). Having a related but non-parent adult aged 20–59 years in the household reduces the odds (OR 0.6; 95% CI 0.5–0.8). There is an inverse relationship between a child’s odds of dying and household socio-economic status. Conclusions This detailed household profile from a poor rural setting where HIV infection is endemic indicates that children are at high risk of dying when another child is very ill or has recently died. Short birth intervals and additional children in the household are further risk factors. Presence of a related adult is protective, as is higher socio-economic status. Such evidence can inform primary health care practice and facilitate targeting of community health

    The study has been conducted in the Potka Block of East Singhbhum district of the state of Jharkhand. The district is mainly dominated by indigenous tribes, such as, Santhal, Munda, Ho, Bhumiz, Kharia, and Sabar. The unit of analysis of the study was an individual. The objectives were to: a) Understand the socio-economic and health status of LAP, b) Know the health seeking behavior and problems faced by the LAP, c) Assess the utilization of the programs related to Leprosy eradication in the study area and d), Suggest various measures for improving the socio-economic and health status of LAP. Fifty Leprosy affected persons (LAP) from the Potka block; comprising of 20% of LAP of that area have been selected as the study sample by using the method of Multi-Stage Random Sampling, with equal representation of men and women. The LAPs included leprosy patients, leprosy treated people and their family members. 39/50 (78%) of the respondents are illiterates and only 3/11 (6%) among the literate population have crossed matriculation and above. This seems to have resulted in the respondent's low level of awareness about the disease, resulting in delayed treatment. 14/25 (56%) percent of female and 13/25 (52%) of male respondents are considered untouchable by their natal families, thus forced to stay in congested leprosy colonies resulting in other social and health related issues. It was observed that leprosy cured children,and also children of LAP are being denied admission iany school, due to the social stigma attached to it. 27/50 (54%)of leprosy patients and leprosy cured people (mostly with visible deformities) were found to practice begging as their sole means of livelihood. Many LAPs are also engaged in cultivation and small scale business particularly among the rural population. An amount of gender disparity was also observed in the employment pattern among the LAPs. Among the, respondents 15/25 (60%) of the females are beggars as compared to 12/25 (48%) of the male

    Background: In cultured, dividing transformed T lymphocytes and in dividing bone marrow cells from normal men and those with a haematological malignancy, sex chromosome aneuploidy has been found to increase in prevalence and degree with age. This has rarely been investigated in non-dividing uncultured blood samples. The loss and gain of the X chromosome in dividing transformed lymphocytes in women with age is much more frequent than that of the Y chromosome in males. However, paradoxically X chromosome aneuploidy is rarely seen in the dividing cells of bone marrow of females. Methods: In blood samples from 565 men with breast cancer and 54 control men from the England and Wales general population, 80 cell nuclei per sample were scored for presence of X and Y chromosomes using fluorescent centromeric probes. Results: Sex chromosome aneuploidy, largely Y chromosome loss, was present in 63% of cases and 57% of controls, with the prevalence and degree of aneuploidy increasingly sharply and highly significantly with age. At ages 65–80 years, 71% of cases and 85% of controls showed aneuploidy and 15% and 25%, respectively, had ⩾10% of cells aneuploid. Allowing for age, aneuploidy was less prevalent (P=0.03) in cases than controls. Conclusion: Sex chromosome aneuploidy in non-dividing nuclei of peripheral blood cells is frequent in adult men, the prevalence and degree increasing sharply with age. The possible relation of sex chromosome aneuploidy to breast cancer risk in men, and to cancer risk generally, needs further investigation, ideally in cohort studies. PMID:23299533

    Structural and diffusion imaging studies demonstrate effects of age, sex, and asymmetry in many brain structures. However, few studies have addressed how individual differences might influence the structural integrity of the superficial white matter (SWM), comprised of short-range association (U-fibers), and intracortical axons. This study thus applied a sophisticated computational analysis approach to structural and diffusion imaging data obtained from healthy individuals selected from the International Consortium for Brain Mapping (ICBM) database across a wide adult age range (n=65, age: 18-74 years, all Caucasian). Fractional anisotropy (FA), radial diffusivity (RD), and axial diffusivity (AD) were sampled and compared at thousands of spatially matched SWM locations and within regions-of-interest to examine global and local variations in SWM integrity across age, sex, and hemisphere. Results showed age-related reductions in FA that were more pronounced in the frontal SWM than in the posterior and ventral brain regions, whereas increases in RD and AD were observed across large areas of the SWM. FA was significantly greater in left temporoparietal regions in men and in the posterior callosum in women. Prominent leftward FA and rightward AD and RD asymmetries were observed in the temporal, parietal, and frontal regions. Results extend previous findings restricted to the deep white matter pathways to demonstrate regional changes in the SWM microstructure relating to processes of demyelination and/or to the number, coherence, or integrity of axons with increasing age. SWM fiber organization/coherence appears greater in the left hemisphere regions spanning language and other networks, while more localized sex effects could possibly reflect sex-specific advantages in information strategies.

    This study attempts to understand the nature of violence suffered by the adolescents of Kolkata (erstwhile Calcutta) and to identify its relation with their socio-economic background and mental health variables such as anxiety, adjustment, and self-concept. It is a cross-sectional study covering a total of 370 adolescents (182 boys and 188 girls) from six higher secondary schools in Kolkata. The data was gathered by way of a semi-structured questionnaire and three standard psychological tests. Findings revealed that 52.4%, 25.1%, and 12.7% adolescents suffered psychological, physical, and sexual violence in the last year. Older adolescents (aged 17-18 years) suffered more psychological violence than the younger ones (15-16 years) (p<0.05). Sixty nine (18.6%) adolescent students stood witness to violence between adult members in the family. More than three-fifth (61.9%) adolescents experienced at least one type of violence, while one-third (32.7%) experienced physical or sexual violence or both. Whatever its nature is, violence leaves a scar on the mental health of the victims. Those who have been through regular psychological violence reported high anxiety, emotional adjustment problem, and low self-concept. Sexual abuse left a damaging effect on self-concept (p<0.05), while psychological violence or the witnessing of violence prompted high anxiety scores (p<0.05), poor emotional adjustment (p<0.05), and low self-concept (p<0.05). This study stresses the need to provide individual counselling services to the maltreated adolescents of Kolkata so that their psychological traumas can heal and that they can move on in life with new hopes and dreams.

    Objectives: Previous studies of older European populations have established that disability and morbidity vary with indicators of socio-economic position (SEP). We undertook a systematic narrative review of the literature to ascertain to what extent there is evidence of similar inequalities in the subjective health and well-being of older people in Europe. Method: Relevant original research articles were searched for using Medline, Global Health, Embase, Social Policy and Practice, Cinahl, Web of Science and International Bibliography of the Social Sciences (IBSS). We included studies of SEP and indicators of subjective health and well-being (self-rated health; life satisfaction; quality of life) conducted since 1991 using population-based samples of older people in Europe and published 1995–2013. Results: A total of 71 studies were identified. Poorer SEP was associated with poorer subjective health and well-being. Associations varied somewhat depending on the SEP measure and subjective health and well-being outcome used. Associations were weaker when social support and health-related behaviours were adjusted for suggesting that these factors mediate the relationship between SEP and subjective health and well-being. Associations tended to be weaker in the oldest age groups. The patterns of associations by gender were not consistent and tended to diminish after adjusting for indicators of health and life circumstances. Conclusion: The results of this systematic narrative review of the literature demonstrate the importance of social influences on later life subjective health and well-being and indicate areas which need further investigation, such as more studies from Eastern Europe, more longitudinal studies and more research on the role of mediating factors.

    Childhood circumstances such as socio-economic status and family structure have been found to influence psychological, psychosocial attributes and Oral Health Related Quality of Life (OHRQoL) in children. Therefore, the aim of this study was to conduct a systematic review of the published literature to assess the influence of parental Socio-Economic Status (SES) and home environment on children's OHRQoL. A systematic search was conducted in August 2013 using PubMed, Medline via OVID, CINAHL Plus via EBSCO, and Cochrane databases. Studies that have analysed the effect of parental characteristics (SES, family environment, family structure, number of siblings, household crowding, parents' age, and parents' oral health literacy) on children's OHRQoL were included. Quality assessment of the articles was done by the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative studies. Database search retrieved a total of 2,849 titles after removing the duplicates, 36 articles were found to be relevant. Most of the studies were conducted on Brazilian children and were published in recent two years. Early Childhood Oral Health Impact Scale and Children's Perception Questionnaire were the instruments of choice in preschool and school aged children respectively. Findings from majority of the studies suggest that the children from families with high income, parental education and family economy had better OHRQoL. Mothers' age, family structure, household crowding and presence of siblings were significant predictors of children's OHRQoL. However, definitive conclusions from the studies reviewed are not possible due to the differences in the study population, parental characteristics considered, methods used and statistical tests performed.

    Increasing population and socio-economic development have put great pressure on water resources of the Yellow River (YR) basin. The anticipated climate and socio-economic changes may further increase water stress. Many studies have investigated the changes in renewable water resources under various climate change scenarios, but few have considered the joint pressure from both climate change and socio-economic development. In this study, we assess water scarcity under various socio-economic pathways with emphasis on the impact of water scarcity on food production. The water demands in the 21st century are estimated based on the newly developed shared socio-economic pathways (SSPs) and renewable water supply is estimated using the climate projections under the Representative Concentration Pathway (RCP) 8.5 scenario. The assessment predicts that the renewable water resources would decrease slightly then increase. The domestic and industrial water withdrawals are projected to increase in the next a few decades and then remain at the high level or decrease slightly during the 21st century. The increase in water withdrawals will put the middle and lower reaches in a condition of severe water scarcity beginning in the next a few decades. If 40 % of the renewable water resources were used to sustain ecosystems, a portion of irrigated land would have to be converted to rain-fed agriculture, which would lead to a 2-11 % reduction in food production. This study highlights the links between water, food and ecosystems in a changing environment and suggests that trade-offs should be considered when developing regional adaptation strategies.

    Rift Valley fever (RVF) is a severe mosquito-borne disease affecting humans and domestic ruminants. RVF virus has been reported in most African countries, as well as in the Arabic Peninsula. This paper reviews the different types of socio-economic impact induced by RVF disease and the attempts to evaluate them. Of the 52 papers selected for this review, 13 types of socio-economic impact were identified according to the sector impacted, the level and temporal scale of the impact. RVF has a dramatic impact on producers and livestock industries, affecting public and animal health, food security and the livelihood of the pastoralist communities. RVF also has an impact on international trade and other agro-industries. The risk of introducing RVF into disease-free countries via the importation of an infected animal or mosquito is real, and the consequent restriction of access to export markets may induce dramatic economic consequences for national and local economies. Despite the important threat of RVF, few studies have been conducted to assess the socio-economic impact of the disease. The 17 studies identified for quantitative analysis in this review relied only on partial cost analysis, with limited reference to mid- and long-term impact, public health or risk mitigation measures. However, the estimated impacts were high (ranging from $5 to $470 million USD losses). To reduce the impact of RVF, early detection and rapid response should be implemented. Comprehensive disease impact studies are required to provide decision-makers with science-based information on the best intervention measure to implement ensuring efficient resource allocation. Through the analysis of RVF socio-economic impact, this scoping study proposes insights into the mechanisms underpinning its often-underestimated importance. This study highlights the need for comparative socio-economic studies to help decision-makers with their choices related to RVF disease management.

    In this article, several findings on socio-economic conditions derived from national reports and a web-based questionnaire are discussed and related to the changing role of forestry and the future forest policy development. A number of Central and South-eastern European countries taking part in a SEE-ERA-NET project ReForMan project ( www.reforman.de ) participated in data acquisition: Austria, Bosnia and Herzegovina, Croatia, Germany, Serbia and Slovenia. The aim of the research was to illustrate the present structure of forestry sector, as well as investigate newly emerging topics in forestry of Central and South-eastern Europe. The results indicated certain patterns in attitudes and perceptions among stakeholders that can be related to socio-economic conditions defined for each country. Clear differences between member and non-member countries exist only in level of implementation of EU legislation. Results showed consensus on main threats to the forests among all countries, but also some country specifics in perceptions of factors influencing forestry, their importance and professional competencies. These results could be additionally explained by influence of historical conditions which shaped development of forest sector in SEE region especially in its organizational dimension as well as in perceived role of forestry expressed through recognition of main forest functions. The influence of European forest policy processes in the region is evident through adaptation of EU legislation and perceived implications of international processes on national levels. Based on this observation, two possible options for future development of the forestry sector can be foreseen: (i) focusing on the productive function of forests and fostering its' sustainable use; or (ii) putting an emphasis on environmental and social issues.

    Boldness in dogs is believed to be one end of the shy-bold axis, representing a super-trait. Several personality traits fall under the influence of this super-trait. Previous studies have found that boldness is affected by breed and breed groups, influences performance in sporting dogs, and is affected in some cases by the sex of the dogs. This study investigated the effects of dog age, sex and reproductive status on boldness in dogs by way of a dog personality survey circulated amongst Australian dog owners. Age had a significant effect on boldness (F=4.476; DF=16,758; P<0.001), with boldness decreasing with age in years. Males were bolder than females (F=19.219; DF=1,758; P<0.001) and entire dogs were bolder than neutered dogs (F=4.330; DF=1,758; P<0.038). The study indicates how behaviour may change in adult dogs as they age and adds to the literature on how sex and reproductive status may affect personality in dogs.

    The rheological properties of blood (viscosity, concentration of red blood cells, erythrocyte sedimantation rate, prothrombin index, and fibrinogen and blood lipid concentration) were studied in apparently healthy subjects of both sexes within the age range from 1 to 75 years. We observed an increase in blood viscosity from infancy to adulthood, followed by a decrease in older age in males. A progressive increase in viscosity is observed in females with aging. We determined three age periods during which the viscosity values remain constant: 1) from the period of early infancy to the second childhood (3.6 ± 0.07 mPa s regardless of sex); 2) from adolescence to the second period of adulthood (5.1 ± 0.06 in men; 4.3 ± 0.05 mPa s in women); 3) elderly and senile age (4.7 ± 0.13 in men; 4.4 ± 0.09 mPa s in women). Sex-related differences in the absolute value of blood viscosity (p < 0.001) were discovered in the period of adulthood. Moreover, we observed sex-related differences in the values of determination coefficients of interrelation between viscosity and the level of red blood cells (R(M)2 = 0.41, p < 0.001; R(F)2 = 0.35, p < 0.001), and viscosity and cholesterol level (R(M)2 = 0.47, p < 0.001; R(F)2 = 0.68, p < 0.001) among men and women. The factor analysis showed that blood viscosity correlates with the concentration of red blood cells by 28%; with the level of fibrinogen, by 23%; with the cholesterol concentration, by 20%.

    The impact of certain exogenous factor (socio-economic, ecological) has been investigated with special attention paid to the parents' living standard, and number of family members on some anthropometric parameters like: body height, body mass, chest circumference, upper leg circumference, upper arm circumference, sitting height, arm length, leg length, pelvis width, shoulders width, lenght of head and with of head on the sample of 698 boys aged 11 to 16 (17) years in the Tuzla region (the northeastern Bosnia, Western Balkan peninsula). Anthropometric measurements have been carried out using methodology proposed by the International Biological program (IBP). The results of these investigations have shown that there is a certain impact of the socio-economic conditions on the growth and development of boys. Children from families that have better living standard are, as a rule, taller, which is indicated by the statistical significant differences (P > 0.01). This trend indicates also value of Body Mass Index (BMI), which is in younger children from the families with lower living standard 16, while in the same category in the children from the families with better living standard it has value 18.5. The real impact of living conditions on the dynamics of development could be the best seen in the period of puberty. The number of children in the family has negative relationship with anthropometric features. Statistically significant differences (P > 0.001) have been detected in numerous analysed features in families with one or two children in comparison with families with three, four, or five children. Therefore, BMI has been significantly lower (16) in children from families with several children, while in the families with one child in the same growth class (11 years) it was significantly higher (17.4). Similar value of BMI (17.9) have children from the families with five children and which are 17 years old. Besides socio-economic conditions, high level of

    Background Worldwide one billion people are living in slum communities and experts projected that this number would double by 2030. Slum populations, which are increasing at an alarming rate in Bangladesh mainly due to rural-urban migration, are often neglected and characterized by poverty, poor housing, overcrowding, poor environment, and high prevalence of communicable diseases. Unfortunately, comparisons between women living in slums and those not living in slums are very limited in Bangladesh. The objectives of the study were to examine the association of living in slums (dichotomized as slum versus non-slum) with selected public health-related variables among women, first without adjusting for the influence of other factors and then in the presence of socio-economic variables. Methods Secondary data was used in this study. 120 women living in slums (as cases) and 480 age-matched women living in other areas (as controls) were extracted from the Bangladesh Demographic and Health Survey 2004. Many socio-economic and demographic variables were analysed. SPSS was used to perform simple as well as multiple analyses. P-values based on t-test and Wald test were also reported to show the significance level. Results Unadjusted results indicated that a significantly higher percent of women living in slums came from country side, had a poorer status by household characteristics, had less access to mass media, and had less education than women not living in slums. Mean BMI, knowledge of AIDS indicated by ever heard about AIDS, knowledge of avoiding AIDS by condom use, receiving adequate antenatal visits (4 or more) during the last pregnancy, and safe delivery practices assisted by skilled sources were significantly lower among women living in slums than those women living in other areas. However, all the unadjusted significant associations with the variable slum were greatly attenuated and became insignificant (expect safe delivery practices) when some socio-economic

    Religion frequently indicates membership of socio-ethnic groups with distinct health behaviours and mortality risk. Determining the extent to which interactions between groups contribute to variation in mortality is often challenging. We compared socio-economic status (SES) and mortality rates of Protestants and Catholics in Scotland and Northern Ireland, regions in which interactions between groups are profoundly different. Crucially, strong equality legislation has been in place for much longer and Catholics form a larger minority in Northern Ireland. Drawing linked Census returns and mortality records of 404,703 people from the Scottish and Northern Ireland Longitudinal Studies, we used Poisson regression to compare religious groups, estimating mortality rates and incidence rate ratios. We fitted age-adjusted and fully adjusted (for education, housing tenure, car access and social class) models. Catholics had lower SES than Protestants in both countries; the differential was larger in Scotland for education, housing tenure and car access but not social class. In Scotland, Catholics had increased age-adjusted mortality risk relative to Protestants but variation among groups was attenuated following adjustment for SES. Those reporting no religious affiliation were at similar mortality risk to Protestants. In Northern Ireland, there was no mortality differential between Catholics and Protestants either before or after adjustment. Men reporting no religious affiliation were at increased mortality risk but this differential was not evident among women. In Scotland, Catholics remained at greater socio-economic disadvantage relative to Protestants than in Northern Ireland and were also at a mortality disadvantage. This may be due to a lack of explicit equality legislation that has decreased inequality by religion in Northern Ireland during recent decades.

    Mouse lemurs (Microcebus spp.) are an exciting new primate model for understanding human aging and disease. In captivity, Microcebus murinus develops human-like ailments of old age after five years (e.g., neurodegeneration analogous to Alzheimer's disease) but can live beyond 12 years. It is believed that wild Microcebus follow a similar pattern of senescence observed in captive animals, but that predation limits their lifespan to four years, thus preventing observance of these diseases in the wild. Testing whether this assumption is true is informative about both Microcebus natural history and environmental influences on senescence, leading to interpretation of findings for models of human aging. Additionally, the study of Microcebus longevity provides an opportunity to better understand mechanisms of sex-biased longevity. Longevity is often shorter in males of species with high male-male competition, such as Microcebus, but mouse lemurs are sexually monomorphic, suggesting similar lifespans. We collected individual-based observations of wild brown mouse lemurs (Microcebus rufus) from 2003–2010 to investigate sex-differences in survival and longevity. Fecal testosterone was measured as a potential mechanism of sex-based differences in survival. We used a combination of high-resolution tooth wear techniques, mark-recapture, and hormone enzyme immunoassays. We found no dental or physical signs of senescence in M. rufus as old as eight years (N = 189, ages 1–8, mean = 2.59±1.63 SE), three years older than captive, senescent congeners (M. murinus). Unlike other polygynandrous vertebrates, we found no sex difference in age-dependent survival, nor sex or age differences in testosterone levels. While elevated male testosterone levels have been implicated in shorter lifespans in several species, this is one of the first studies to show equivalent testosterone levels accompanying equivalent lifespans. Future research on captive aged individuals can determine

    Tropical lowland rainforests are increasingly threatened by the expansion of agriculture and the extraction of natural resources. In Jambi Province, Indonesia, the interdisciplinary EFForTS project focuses on the ecological and socio-economic dimensions of rainforest conversion to jungle rubber agroforests and monoculture plantations of rubber and oil palm. Our data confirm that rainforest transformation and land use intensification lead to substantial losses in biodiversity and related ecosystem functions, such as decreased above- and below-ground carbon stocks. Owing to rapid step-wise transformation from forests to agroforests to monoculture plantations and renewal of each plantation type every few decades, the converted land use systems are continuously dynamic, thus hampering the adaptation of animal and plant communities. On the other hand, agricultural rainforest transformation systems provide increased income and access to education, especially for migrant smallholders. Jungle rubber and rubber monocultures are associated with higher financial land productivity but lower financial labour productivity compared to oil palm, which influences crop choice: smallholders that are labour-scarce would prefer oil palm while land-scarce smallholders would prefer rubber. Collecting long-term data in an interdisciplinary context enables us to provide decision-makers and stakeholders with scientific insights to facilitate the reconciliation between economic interests and ecological sustainability in tropical agricultural landscapes.

  4. Socio-Economic Instability and the Scaling of Energy Use with Population Size.

    The size of the human population is relevant to the development of a sustainable world, yet the forces setting growth or declines in the human population are poorly understood. Generally, population growth rates depend on whether new individuals compete for the same energy (leading to Malthusian or density-dependent growth) or help to generate new energy (leading to exponential and super-exponential growth). It has been hypothesized that exponential and super-exponential growth in humans has resulted from carrying capacity, which is in part determined by energy availability, keeping pace with or exceeding the rate of population growth. We evaluated the relationship between energy use and population size for countries with long records of both and the world as a whole to assess whether energy yields are consistent with the idea of an increasing carrying capacity. We find that on average energy use has indeed kept pace with population size over long time periods. We also show, however, that the energy-population scaling exponent plummets during, and its temporal variability increases preceding, periods of social, political, technological, and environmental change. We suggest that efforts to increase the reliability of future energy yields may be essential for stabilizing both population growth and the global socio-economic system.

    In recent years scientific literature has seen an increase in publications describing new transgenic applications. Although technically-sound, these promising developments might not necessarily translate into products available to the consumer. This article highlights the impact of external factors on the commercial viability of Genetically Modified (GM) animals in the pharmaceutical and food sectors. Through the division of the production chain into three Policy Domains -Science, Market and Public- I present an overview of the broad range of regulatory and socio-economic components that impacts on the path towards commercialisation of GM animals. To further illustrate the unique combination of forces that influence each application, I provide an in-depth analysis of two real cases: GM rabbits producing human polyclonal antibodies (pharmaceutical case study) and GM cows producing recombinant human lactoferrin (food case study). The inability to generalise over the commercial success of a given transgenic application should encourage researchers to perform these type of exercises early in the R & D process. Furthermore, through the analysis of these case studies we can observe a change in the biopolitics of Genetically Modified Organisms (GMOs). Contrary to the GM plant biopolitical landscape, developing states such as China and Argentina are placing themselves as global leaders in GM animals. The pro-GM attitude of these states is likely to cause a shift in the political evolution of global GMO governance.

    This article serves as an introduction to this special issue, "China's Forest Carbon Sequestration", representing major results of a project sponsored by the Canadian International Development Agency and the Chinese Academy of Sciences. China occupies a pivotal position globally as a principle emitter of carbon dioxide, as host to some of the world's largest reforestation efforts, and as a key player in international negotiations aimed at reducing global greenhouse gas emission. The goals of this project are to develop remote sensing approaches for quantifying forest carbon balance in China in a transparent manner, and information and tools to support land-use decisions for enhanced carbon sequestration (CS) that are science based and economically and socially viable. The project consists of three components: (i) remote sensing and carbon modeling, (ii) forest and soil assessment, and (iii) integrated assessment of the socio-economic implications of CS via forest management. Articles included in this special issue are highlights of the results of each of these components.

    Wind power can play an interesting role in irrigation projects in different areas. A simple methodology has been developed in previous papers for technical evaluation of windmills for irrigation water pumping [1]. This methodology can determine the feasibility of the technology and the levels of daily irrigation demand satisfied by windmills at different levels of risk, using tomato (Lycopersicon esculentum Mill) as greenhouse crop. The present work compared the feasibility of the technology and the critical factors involved in three different countries: Cuba, Spain and Pakistan. The study considered as factors the wind speed level, the energy cost, the tomato prices, the reliability and distance to the electrical grid, and the crop development dates, determining the economic feasibility for each combination of factors in each country. Countries have been selected because of their different socio-economical frameworks, leading to different critical factors. References [1] Peillón, M., Sánchez, R., Tarquis, A.M., García, J.L.

    Growing interest in the equity and sustainability of water funds and other investment in watershed services programs has spurred interest in evaluation of program impacts on ecosystem services and human well-being. Yet, programs often lack a systematic framework to select indicators that are both important to stakeholders and relevant to hypothesized program impact. To fill this gap, we developed a participatory indicator selection methodology and piloted it in Fondo Agua por La Vida y la Sostenibilidad in the East Cauca Valley Colombia. We started by linking program activities to anticipated ecological and socio-economic impacts through stakeholder developed results chains. Using results chains as the framework, we constructed fuzzy cognitive models to explore the relative impact of program activities on social and ecological attributes. To prioritize indicators to monitor, we combined our fuzzy modelling results with an assessment of the perceived importance of different attributes for stakeholders in the water fund. We used the selected indicators to design a monitoring program that will allow the water fund to track and communicate its impact over the long-term.

    Deciding how best to respond to the challenge of climate change requires anticipating not only how climate might change in the future, but how society might change as well. Changes in population and economic growth, innovation, technological development, governance, culture, and lifestyle all will affect the energy use and land use that drive climate change, as well as society's capacity to reduce emissions or adapt to climate change impacts. Developing a set of alternative scenarios for societal development is one way to capture and explore the uncertainty in future conditions. The climate change research community has produced a new set of five such scenarios, called Shared Socio-Economic Pathways (SSPs), that is intended to underpin scientific studies, assessments, and policy dialogues for the next decade or more. The SSPs include both qualitative narratives and quantitative projections of key elements such as population, economic growth, urbanization, and educational attainment. They are designed to span a wide range of future conditions in terms of the challenges they present to both adaptation and mitigation. The SSPs are one component of a larger scenario framework which also includes a set of radiative forcing pathways and climate model simulations based on them. Alternative climate futures will be integrated with the alternative societal futures represented by the SSPs to investigate climate change impacts as well as mitigation and adaptation response options.

    The study of risk contagion in economic networks has most often focused on the financial liquidities of institutions and assets. In practice the agents in a network affect each other through social contagion, i.e., through herd behavior and the tendency to follow leaders. We study the coupled risk between social and economic contagion and find it significantly more severe than when economic risk is considered alone. Using the empirical network from the China venture capital market we find that the system exhibits an extreme risk of abrupt phase transition and large-scale damage, which is in clear contrast to the smooth phase transition traditionally observed in economic contagion alone. We also find that network structure impacts market resilience and that the randomization of the social network of the market participants can reduce system fragility when there is herd behavior. Our work indicates that under coupled contagion mechanisms network resilience can exhibit a fundamentally different behavior, i.e., an abrupt transition. It also reveals the extreme risk when a system has coupled socio-economic risks, and this could be of interest to both policy makers and market practitioners.

    2013-05-01

    Financial and economic history is strewn with bubbles and crashes, booms and busts, crises and upheavals of all sorts. Understanding the origin of these events is arguably one of the most important problems in economic theory. In this paper, we review recent efforts to include heterogeneities and interactions in models of decision. We argue that the so-called Random Field Ising model ( rfim) provides a unifying framework to account for many collective socio-economic phenomena that lead to sudden ruptures and crises. We discuss different models that can capture potentially destabilizing self-referential feedback loops, induced either by herding, i.e. reference to peers, or trending, i.e. reference to the past, and that account for some of the phenomenology missing in the standard models. We discuss some empirically testable predictions of these models, for example robust signatures of rfim-like herding effects, or the logarithmic decay of spatial correlations of voting patterns. One of the most striking result, inspired by statistical physics methods, is that Adam Smith's invisible hand can fail badly at solving simple coordination problems. We also insist on the issue of time-scales, that can be extremely long in some cases, and prevent socially optimal equilibria from being reached. As a theoretical challenge, the study of so-called "detailed-balance" violating decision rules is needed to decide whether conclusions based on current models (that all assume detailed-balance) are indeed robust and generic.

    Increasing scarcity, growing demand, and a burdened water supply have generated concerns about the sustainability of the southwest's regional water infrastructure. This necessitates the adoption of improved water management practices and policies better suited to contemporary water resource dilemmas. Scenarios introduce an innovative aspect to strategic long-term planning that is currently absent from current decision- making and resource management activities. For the purpose of assessing future water resources management and sustainability needs within the region, the formal approach to scenario development adopted by scientists and researchers at the University of Arizona's SAHRA (Sustainability of semi-Arid Hydrology and Riparian Areas) center is adopted. Through workshops and meetings with regional and state stakeholders, several dominant themes of interest for water resources management emerged. A historical analysis of several key variables associated with these major themes provided insight on the future uncertainty in projections and assumptions adopted in early examples of future planning in the southwest. Analysis of these key variables indicates that historical assumptions and projections in the dimensions of the environment, climate, and socio-economics lacked the dynamic planning foresight that tools such as scenarios can provide.

    Bushfires are becoming one of the environmental challenges confronting Ghana and increasingly it has become difficult for the Government to control it because this activity is deeply rooted in the socio-cultural and economic systems of the people. The effects of bushfire on rural livelihoods and on the ecosystem in Ghana are extensive and damaging. Bushfires have accelerated environmental degradation especially in the fragile savannah ecosystem, yet there is very little in the form of public education, published data and information concerning the frequency, intensity, duration and effects of bushfire on the environment and human welfare in Ghana. The study did a change detection of biomass cover using pre and post fire normalized burnt ratio of Landsat TM+ imageries of 2002 and 2003 to determine fire severity on vegetative cover. The socio-economic impact of this disaster was collected using social survey approaches such as interviews and focus group meetings. Some of the consequences of the bushfire include the burning of food stuffs, houses as well as domestic animals. The environmental impacts of these bushfires have been very devastating and these involve the lost of biodiversity (plants and animals) and the depletion of organic matter of the soil thus impoverishing the soils. The research found out that, the continuous prevalence of this activity was due to the laxity in the implementation of bye-laws regulating bushfire burning due to the lack of personnel and logistics to state agencies in the District to combat the problem.

    Studies of adults and adolescents suggest subjective socio-economic status (SES) is associated with health/well-being even after adjustment for objective SES. In adolescence, objective SES may have weaker relationships with health/well-being than at other life stages; school-based social status may be of greater relevance. We investigated the associations which objective SES (residential deprivation and family affluence), subjective SES and three school-based subjective social status dimensions (“SSS-peer”, “SSS-scholastic” and “SSS-sports”) had with physical symptoms, psychological distress and anger among 2503 Scottish 13–15 year-olds. Associations between objective SES and health/well-being were weak and inconsistent. Lower subjective SES was associated with increased physical symptoms and psychological distress, lower SSS-peer with increased psychological distress but reduced anger, lower SSS-scholastic with increased physical symptoms, psychological distress and anger, and lower SSS-sports with increased physical symptoms and psychological distress. Associations did not differ by gender. Objective and subjective SES had weaker associations with health/well-being than did school-based SSS dimensions. These findings underline the importance of school-based SSS in adolescence, and the need for future studies to include a range of school-based SSS dimensions and several health/well-being measures. They also highlight the need for a focus on school-based social status among those working to promote adolescent health/well-being. PMID:25306408

    New evidence for the tissue types exploited by early hominids from carcasses possibly acquired through scavenging is derived from the larger mammal bone assemblages from FLK I, level 22 (Zinjanthropus floor), and FLKN levels 1 and 2 from Bed I, Olduvai Gorge, Tanzania. Published skeletal part profiles from the two archaeological sites are evaluated using (i) modern observations on the sequence by which carnivores consume carcass parts in order to assess the timing of hominid access to carcasses, and (ii) measurements of flesh and marrow yields to assess the tissue types sought and acquired. These results suggest that the maximization of marrow (fat) yields, not flesh (protein) yields, was the criterion shaping decisions about carcass processing. Because of evidence for density-dependent destruction of some flesh-bearing parts by scavengers of the hominid-butchered assemblages, however, it is uncertain whether carcass parts were transported and acquired by hominids in a largely defleshed condition. The results on tissue types acquired are combined with a discussion of predation risk, feeding competition and the equipment needs of carcass processing in an attempt to identify archaeological test implications of competing hypotheses for the socio-economic function of the earliest archaeological sites.

    This study investigated students' scientific epistemological beliefs in relation to socio-economic status (SES) and gender. Data were obtained from 1,152 eight grade Turkish elementary school students using Scientific Epistemological Beliefs instrument. Canonical correlation analysis indicated that students with a working mother and educated parents as well as greater number of books at home together with a separate study room are more likely to have tentative views and less likely to have fixed views about science compared to students with unemployed mother, uneducated parents, less books at home, and no separate study room. Generally, results revealed while family SES correlated positively with tentative views, it was negatively associated with fixed views, implying that students from high SES family were more likely to believe that knowledge is uncertain and not handed down by authority compared to students from low SES family. This study, however, failed to indicate any relationship between father work-status, buying daily newspaper and epistemological beliefs. In addition, Multivariate Analysis of Variance indicated that boys more likely to have tentative beliefs compared to girls.

    Age and sex patterns of migration are essential for understanding drivers of population change and heterogeneity of migrant groups. We develop a hierarchical Bayesian model to estimate such patterns for international migration in the European Union and European Free Trade Association from 2002 to 2008, which was a period of time when the number of members expanded from 19 to 31 countries. Our model corrects for the inadequacies and inconsistencies in the available data and estimates the missing patterns. The posterior distributions of the age and sex profiles are then combined with a matrix of origin-destination flows, resulting in a synthetic database with measures of uncertainty for migration flows and other model parameters.

    Each component of the web space, a three-dimensional structure, should be carefully created during reconstruction of web space loss. One of these web space components is the web height. In this study, the dorsal view of subjects' hands was analyzed to determine the web height ratios. The web height ratios were then compared with respect to age and sex. The second and third web height ratios differed between adult men and women and between children and adults. However, no differences were observed among children. This study is unique because it focuses on the web height ratios of all web spaces according to age and sex and provides a very easy-to-use scale that may help surgeons to perform web space reconstruction. Moreover, the present study adds to the literature by providing information on the first web height ratios of the hand.

    Life-history (LH) theory predicts that selection will optimize the trade-off between reproduction and somatic maintenance. Reproductive ageing and finite life span are direct consequences of such optimization. Sexual selection and conflict profoundly affect the reproductive strategies of the sexes and thus can play an important role in the evolution of life span and ageing. In theory, sexual selection can favor the evolution of either faster or slower ageing, but the evidence is equivocal. We used a novel selection experiment to investigate the potential of sexual selection to influence the adaptive evolution of age-specific LH traits. We selected replicate populations of the seed beetle Callosobruchus maculatus for age at reproduction ("Young" and "Old") either with or without sexual selection. We found that LH selection resulted in the evolution of age-specific reproduction and mortality but these changes were largely unaffected by sexual selection. Sexual selection depressed net reproductive performance and failed to promote adaptation. Nonetheless, the evolution of several traits differed between males and females. These data challenge the importance of current sexual selection in promoting rapid adaptation to environmental change but support the hypothesis that sex differences in LH-a historical signature of sexual selection-are key in shaping trait responses to novel selection.

The mechanisms responsible for the changes in age-sex capture ratios are discussed and indicate that modified Clover traps selectivity capture mule deer, thus introducing bias into population sampling.

    As age and sex affect the function of the lower urinary tract, we studied the characteristics of adrenergic and cholinergic receptors in various parts of lower urinary tract smooth muscle of young (6 months) and old (4 1/2-5 years) male and female rabbits. Saturation experiments performed with (3H)prazosin, (3H)yohimbine, (3H)dihydroalprenolol and (3H)quinuclidinyl benzylate in rabbit bladder base, bladder dome and urethra indicate the presence of regional, sex- and age-related differences in the density of alpha-1, alpha-2, and beta adrenergic and muscarinic cholinergic receptors. Alpha-2 adrenergic receptor density is considerably higher in the female than in the male urethra of both age groups, whereas the higher density of beta adrenergic receptors in the female than in the male bladder base is observed only in the younger animals. The density of muscarinic receptors is higher in bladder dome than in bladder base or urethra in young rabbits of both sexes. In the old animals, the density of muscarinic receptors in bladder base increases to the level observed in bladder dome. Inhibition experiments with selective adrenergic agonists and antagonists indicate that the pharmacological profiles of alpha-2 adrenergic receptors in the urethra and beta adrenergic receptors in the bladder dome and bladder base are similar in both sexes and at both ages. Beta-2 adrenergic receptors are shown to be predominant in bladder base and bladder dome of rabbits. Parallel studies in rabbit urethra, adult rat cortex and neonatal rat lung show that the urethral alpha-2 adrenergic receptors are of the alpha-2A subtype.

    Abstract Functional connectivity (FC) in resting-state functional magnetic resonance imaging (rs-fMRI) is widely used to find coactivating regions in the human brain. Despite its widespread use, the effects of sex and age on resting FC are not well characterized, especially during early adulthood. Here we apply regression and graph theoretical analyses to explore the effects of sex and age on FC between the 116 AAL atlas parcellations (a total of 6670 FC measures). rs-fMRI data of 494 healthy subjects (203 males and 291 females; age range: 22–36 years) from the Human Connectome Project were analyzed. We report the following findings.

    Are cognitive sex differences magnified by individual differences in age, sex hormones, or puberty development? Cross-sectional samples of 12- to 14-year-old boys (n = 85) and girls (n = 102) completed tasks assessing episodic memory, face recognition, verbal fluency, and mental rotations. Blood estradiol, free testosterone, and self-rated puberty scores were obtained. Sex differences were found on all cognitive measures. However, the magnitude was not larger for older children, hormones and cognitive performance were not associated, and early maturers did not perform better than late maturers. Thus, cognitive sex differences were not associated with age, levels of sex hormones, or puberty development.

    Objective: Due to importance and progressive growth of apartment-living phenomenon in the world today, it is essential to survey the different dimensions of this modern lifestyle. The aim of this study is to predict rate of apartment-living based on the different predicted variables of socio-economic and demographic factors with approach to different health aspects. Methods: A descriptive- analytic study was carried out between 600 apartment and 800 non-apartment residents in the Shiraz (Southern Region of Iran) through multi-stage cluster sampling during the year 2011. The statistical analysis was performed on the obtained data using multi-variable logistic regression as well as ANOVA analysis. Result: The rate for apartment-living in above 30 years old age group was 8.31 times more than 15-30 years old, 9.6 times more in employed vs. unemployed; 6.57 and 9.49 times more in families with average and high monthly incomes, respectively, vs. family with low monthly income; 8.73 times more in owner sub-group vs. renter sub-group; and 1.30 times more in people living lonely than those living with family. People living in an apartment are in poor health status considering physical, mental and social aspects. Conclusion: Based on the results, it is very important that policy makers in urban areas consider the determinative role of socio-economic and demographic factors, which are involved in selecting apartment-living lifestyle by urban residents and also are effective on health.

    The objective of our study was to identify how actors from the main socio-economic sectors perceive their interactions and impacts on a sensitive wetland in an arid climate, specifically the salt pans of Chott Merouane in Algeria. The results revealed that there are three main economic stakes including agriculture, livestock production and salt mining, each activity providing a great benefit for local and national populations. The local population perceived that the current activities are conducted in such a way that they created conflict between socio-economic sectors and caused a threat for long term sustainability of the wetlands. The results highlighted the need to initiate an integrated management approach between the different sectors and to develop a shared vision for the territory.

    Bushmeat represents an important source of animal protein for humans in tropical Africa. Unsustainable bushmeat hunting is a major threat to wildlife and its consumption is associated with an increased risk of acquiring zoonotic diseases, such as Ebola virus disease (EVD). During the recent EVD outbreak in West Africa, it is likely that human dietary behavior and local attitudes toward bushmeat consumption changed in response to the crisis, and that the rate of change depended on prevailing socio-economic conditions, including wealth and education. In this study, we therefore investigated the effects of income, education, and literacy on changes in bushmeat consumption during the crisis, as well as complementary changes in daily meal frequency, food diversity and bushmeat preference. More specifically, we tested whether wealthier households with more educated household heads decreased their consumption of bushmeat during the EVD crisis, and whether their daily meal frequency and food diversity remained constant. We used Generalized Linear Mixed Models to analyze interview data from two nationwide household surveys across Liberia. We found an overall decrease in bushmeat consumption during the crisis across all income levels. However, the rate of bushmeat consumption in high-income households decreased less than in low-income households. Daily meal frequency decreased during the crisis, and the diversity of food items and preferences for bushmeat species remained constant. Our multidisciplinary approach to study the impact of EVD can be applied to assess how other disasters affect social-ecological systems and improve our understanding and the management of future crises.

    Management changes can induce significant alterations of soil organic carbon (SOC) stocks. Including trends in SOC within a certain land-use category can thus strongly influence the annual national inventory reports for greenhouse gas emissions. In 2013, the European Union has therefore decided that all member states shall report the evolvement of SOC within agricultural soils to increase the incentives to mitigate climate change by improving the management of those soils. Here, we present the country and county-wise SOC trends in Swedish agricultural mineral soils on the basis of three soil inventories conducted between 1988 and 2013. In the past two decades, the average topsoil (0-20 cm) SOC content of the whole country increased from 2.48% to 2.67% representing a relative change of 7.7% or 0.38% yr-1. This is in contrast to trends observed in neighboring countries such as Norway and Finland. We attributed this positive SOC trend to the increasing cultivation of leys throughout the country. Indeed, the below-ground carbon input of perennial grasses is up to fourfold as compared to cereals, which leads to a significant soil carbon sequestration potential under cropping systems with ley. The increase in ley proportion was significantly correlated to the increase in horse population in each county (R2=0.71), which has more than doubled in the past three decades. Due to subsidies introduced in the early 1990s, the area as long-term set-aside land (mostly old leys) also contributed to an increase in leys. This discloses the strong impact of rather local socio-economic trends on soil carbon storage, which also need to be considered in larger-scale model applications. This database is used in the continuous validation process of the Swedish national system for reporting changes in SOC stocks.

  10. Childhood disability and socio-economic circumstances in low and middle income countries: systematic review

    PubMed Central

    2011-01-01

    Background The majority of children with disability live in low and middle income (LAMI) countries. Although a number of important reviews of childhood disability in LAMI countries have been published, these have not, to our knowledge, addressed the association between childhood disability and the home socio-economic circumstances (SEC). The objective of this study is to establish the current state of knowledge on the SECs of children with disability and their households in LAMI countries through a systematic review and quality assessment of existing research. Methods Electronic databases (MEDLINE; EMBASE; PUBMED; Web of Knowledge; PsycInfo; ASSIA; Virtual Health Library; POPLINE; Google scholar) were searched using terms specific to childhood disability and SECs in LAMI countries. Publications from organisations including the World Bank, UNICEF, International Monetary Fund were searched for. Primary studies and reviews from 1990 onwards were included. Studies were assessed for inclusion, categorisation and quality by 2 researchers. Results 24 primary studies and 13 reviews were identified. Evidence from the available literature on the association between childhood disability and SECs was inconsistent and inconclusive. Potential mechanisms by which poverty and low household SEC may be both a cause and consequence of disability are outlined in the reviews and the qualitative studies. The association of poor SECs with learning disability and behaviour problems was the most consistent finding and these studies had low/medium risk of bias. Where overall disability was the outcome of interest, findings were divergent and many studies had a high/medium risk of bias. Qualitative studies were methodologically weak. Conclusions This review indicates that, despite socially and biologically plausible mechanisms underlying the association of low household SEC with childhood disability in LAMI countries, the empirical evidence from quantitative studies is inconsistent and

    The present study comprised 1000 child and young workers in small and medium-size industries in Alexandria, as well as 250 control subjects. Almost all young workers work for more than 40 hours/week and suffer from fatigue. Workers' family needs rather than the lack of family care is the responsible factor for sending the child to work, and the economic problems seem to be the underlying factor for all other problems of child labour. Work improves labourers' socio-economic status and smoking habit, and provides a chance for their personal contacts and interactions, which are reflected on their level of intellectual capabilities; however, it has some impact on their food habits affecting their achievement of balanced diet; and no drug addiction exists among all the studied subjects. Noise and dust represent the main occupational exposures (84.4% and 55.8% respectively), followed by exposure to heat (25.3%), vapors and gases (10.4%) and biological materials (9.0%), and nearly 2/3 of the workers have combined exposures. Work injuries occurred to 18.4% of the workers and 7.4% had more than one injury during employment; however, nearly 1/3 of the injuries required absenteeism off work and/or hospitalization. The injuries have been typically related to industrial operations, occurring mostly to hands and fingers (80.4%), and are mainly attributed to lack of training (63.0%). The health services presented to the workers are very poor. The study has been concluded by recommending making the work safe, free from hazards, and ergonomically fit to children, providing educational and training services, covering young workers by social security, and revising legislation of child labour.

    In spite of official intentions to reduce inequalities at University, students' socio-economic status (SES) is still a major determinant of academic success. The literature on the dual function of University suggests that University serves not only an educational function (i.e., to improve students' learning), but also a selection function (i.e., to compare people, and orient them towards different positions in society). Because current assessment practices focus on the selection more than on the educational function, their characteristics fit better with norms and values shared by dominant high-status groups and may favour high-SES students over low-SES students in terms of performances. A focus on the educational function (i.e., mastery goals), instead, may support low-SES students' achievement, but empirical evidence is currently lacking. The present research set out to provide such evidence and tested, in two field studies and a randomised field experiment, the hypothesis that focusing on University's educational function rather than on its selection function may reduce the SES achievement gap. Results showed that a focus on learning, mastery-oriented goals in the assessment process reduced the SES achievement gap at University. For the first time, empirical data support the idea that low-SES students can perform as well as high-SES students if they are led to understand assessment as part of the learning process, a way to reach mastery goals, rather than as a way to compare students to each other and select the best of them, resulting in performance goals. This research thus provides a theoretical framework to understand the differential effects of assessment on the achievement of high and low-SES students, and paves the way toward the implementation of novel, theory-driven interventions to reduce the SES-based achievement gap at University.

    Abstract Introduction The behaviour of parents in ensuring car passenger safety for their children is associated with socio-economic (SE) status of the family; however, the influence of parental education has rarely been researched and the findings are contradictory. The aim of the study was to clarify whether parental education influences the use of a child car seat during short rides. Methods A cross-sectional survey was carried out in outpatient clinics for children’s healthcare across Slovenia. 904 parents of 3-year-old children participated in the study; the response rate was 95.9%. A self-administered questionnaire was used. A binary multiple logistic regression was applied to assess the association between parental unsafe behaviour as dependent variable, and education and other SE factors as independent variables. Results 14.6% of parents did not use a child car seat during short rides. Families where mother had low or college education had higher odds of the non-use of a child car seat than families where mother had a university education. Single-parent families and those who lived in areas with low or medium SE status also had higher odds of the non-use of a child car seat. Conclusions Low educational attainment influences parents’ behaviour regarding the non-use of a child car seat. Low parental education is not the only risk factor since some highly educated parents also have high odds of unsafe behaviour. All parents should therefore be included in individually tailored safety counselling programmes. SE inequalities could be further reduced with provision of free child car seats for eligible families.

    Scent is used across taxa to communicate information about signaler identity. Eurasian otters Lutra lutra are mainly solitary and thought to use scent as their primary means of communication. Little is known, however, about what information otters communicate through scent or what social function this performs. Headspace solid-phase microextraction and gas chromatography-mass spectrometry were used to sample and analyze volatile organic compounds from anal scent gland secretion from 158 otters of differing sex, age, and female reproductive status. Univariate and multivariate differences were clear between adult and juvenile otters. Complex sex differences were apparent in adult otters but not in younger individuals, suggesting the use of this scent secretion in mate attraction. The scent of pregnant and lactating females was highly differentiated from male and juvenile scent, but anecdotal reports suggest females avoid communication during these times.

    Nowadays, many forms of reproduction coexist in nature: Asexual, sexual, apomictic and meiotic parthenogenesis, hermaphroditism and parasex. The mechanisms of their evolution and what made them successful reproductive alternatives are very challenging and debated questions. Here, using a simple evolutionary aging model, we give a possible scenario. By studying the performance of populations where individuals may have diverse characteristics-different ploidies, sex with or without crossing over, as well as the absence of sex-we find an evolution sequence that may explain why there are actually two major or leading groups: Sexual and asexual. We also investigate the dependence of these characteristics on different conditions of fertility and deleterious mutations. Finally, if the primeval organisms on Earth were, in fact, asexual individuals we conjecture that the sexual form of reproduction could have more easily been set and found its niche during a period of low-intensity mutations.

    Financial restraints and poverty lead to poor diets and poor health outcomes. Limited research shows that socioeconomic status is related to home availability of certain foods. However, studies in this area have used different socio-economic indicators, which may not equally influence eating-related behaviors. Using multiple indicators of socio-economic status may provide a more accurate picture of these relationships. The aim of this study was to investigate whether several socio-economic indicators are independently associated with home availability of selected foods known to influence chronic disease risk in 50 year olds from Canterbury, New Zealand, participating in the CHALICE study. Participants were selected randomly from health research extracts from Canterbury. Data from 216 participants (110 females, 106 males) were included. The presence (but not quantity) of foods/beverages in the home was measured by a validated home food inventory. Linear regression analyses were performed for the following home food inventory scores: fruit, vegetables, lower fat dairy, obesogenic foods and sweetened beverages with household income, standard of living and education using multivariate models. Higher household income and standard of living were individually associated with a 2% to 3% higher fruit and vegetables (3 to 5 types/forms) and total food scores (6 to 9 types/forms) (p<0.03). Higher education level was associated with a 2.5% increase in fruit and vegetables score (4 types/forms) and an 8% decrease in sweetened beverages score (0.4 beverages) (p<0.02). These results suggest that using only one measure of socio-economic status cannot accurately capture the effects of social inequalities in food availability. Those experiencing the most social disadvantage had a lesser availability of fruit and vegetables which may be detrimental to good health.

    This paper investigates household dissolution and changes in asset wealth (socio-economic position) in a rural South African community containing settled refugees. Survival analysis applied to a longitudinal dataset indicated that the covariates increasing the risk of forced household dissolution were a reduction in socio-economic position (asset wealth), adult deaths and the permanent outmigration of more than 40% of the household. Conversely, the risk of dissolution was reduced by bigger households, state grants and older household heads. Significant spatial clusters of former refugee villages also showed a higher risk of dissolution after 20 years of permanent residence. A discussion of the dynamics of dissolution showed how an outflow/inflow of household assets (socio-economic position) was precipitated by each of the selected covariates. The paper shows how an understanding of the dynamics of forced household dissolution, combined with the use of geo-spatial mapping, can inform inter-disciplinary policy in a rural community.

    Vladimir (Volodya) Keilis-Borok has pioneered the use of pattern recognition as a technique for analyzing and forecasting developments in natural as well as socio-economic systems. Keilis-Borok's work on predicting earthquakes and landslides using this technique as a leading geophysicist has been recognized around the world. Keilis-Borok has also been a world leader in the application of pattern recognition techniques to the analysis and prediction of socio-economic systems. He worked with Allan Lichtman of American University in using such techniques to predict presidential elections in the U.S. Keilis-Borok and I have worked together with others on the use of pattern recognition techniques to analyze and to predict socio-economic systems. We have used this technique to study the pattern of macroeconomic indicators that would predict the end of an economic recession in the U.S. We have also worked with officers in the Los Angeles Police Department to use this technique to predict surges of homicides in Los Angeles.

    HIV related stigma and discrimination is a known barrier for HIV prevention and care. We aimed to assess the relationship between socio-economic status (SES) and HIV related stigma in Zimbabwe. This paper uses data from Project Accept, which examined the impact of community-based voluntary counseling and testing intervention on HIV incidence and stigma. Total of 2522 eligible participants responded to a psychometric assessment tool, which assessed HIV related stigma and discrimination attitudes on 4 point Likert scale. The tool measured three components of HIV-related stigma: shame, blame and social isolation, perceived discrimination, and equity. Participants’ ownership of basic assets was used to assess the socio-economic status. Shame, blame and social isolation component of HIV related stigma was found to be significantly associated with medium [odds ratio (OR)=1.73, P<0.01] and low SES (OR=1.97, P<0.01), indicating more stigmatizing attitudes by participants belonging to medium and low SES in comparison to high SES. For HIV related stigma and discrimination programs to be effective, they should take into account the socio-economic context of target population. PMID:28299151

    This study aimed at establishing the determinants and distribution of the health-seeking behaviours of Port Harcourt residents, and comparing them between the upper and lower socio-economic classes. A descriptive cross-sectional study using 204 respondents was carried out. The socio-economic classification used occupation and average monthly income. Multi-staged sampling technique was used; stage one being by stratified sampling using socio-economic classes for stratification; stage two involved clustered sampling; following which five-sectioned structured questionnaires were administered. Differences (P<0.05) in Health facility used existed: the upper class used mostly Government and Private Hospitals; the lower class additionally used health centres and un-orthodox health facilities. Reasons for using a health facility was similar (P>0.05) as both classes mostly go for treatment or medical check-ups. Health facility preference was mostly for good treatment outcome and accessibility; cost also, for the lower class. Commonly and last used health-care giver differed (P<0.05); upper class mostly saw a doctor, the lower saw the doctor, pharmacist and nurse. Competence; the major reason for health-care giver selection by the upper class differed (P<0.05) from the lower that had previous good treatment outcome and illness severity. The upper socioeconomic classed have better health-seeking behaviours because they use more competent Health facilities and health-care givers. PMID:28299098

    Availability of Highly Active Anti-Retroviral Treatment (HAART) has modified the natural history of HIV infection, resulting in increase of seropositive subjects survival. The aim of the study was to assess patients' survival in relation to socio-economic status in HAART era using Functional Multidimensional Evaluation questionnaire. A three-level Socio-Economic Index (SEI) combining results from self-perception of unmet needs and objective data from the assessment of the two dimensions has been set up by the authors. Of the 382 subjects interviewed, 102 had been lost to follow-up. SEI showed that 66.4% of the sample faced unmet social or economic needs and 17.1% had unmet needs in both areas. There was a significant relationship between the self-sufficiency in performing Activities of Daily Living (ADL), Clinical Staging, CD4 cell count, SEI and risk of death. The lowest level of SEI was associated with a doubled risk of death compared to SEI upper level. Availability of social and economics support have a positive effect upon survival in patients with HIV infection, also in case of availability of HAART. The combination of subjective and objective assessment of socio-economic resources allows a better understanding of their impact on survival.

    Alam, Rashidah Zainal; Siwar, Chamhuri; Ludin, Norasikin Ahmad

    Malaysia's energy sector is highly dependent on fossil fuels as a primary energy source. Economic growth and socio-economic wellbeing also rely on the utilization of energy in daily life routine. Nevertheless, the increasing cost for electricity and declining fossil fuels resources causes various negative impacts to the people and environment especially in rural areas. This prompted Malaysia to shift towards alternative energy sources such as solar energy to ensure social, economic and environmental benefits. The solar energy is one of the potential renewable energy sources in tropical countries particularly in Malaysia. The paper attempts to analyze the benefits and advantages related to energy efficiency of solar for sustainable energy use and socio economic wellbeing in rural areas, Malaysia. The paper uses secondary sources of data such as policies, regulations and research reports from relevant ministries and agencies to attain the objectives. As a signatory country to the UN Convention on Climate Change and the Kyoto Protocol, Malaysia has taken initiatives for decreasing energy dependence on oil to reduce greenhouse gas emissions (GHG) for sustainable development. The paper shows solar energy becomes one of the promising alternative energy sources to alleviate energy poverty in Malaysia for rural areas. Finally, solar energy has increased socio-economic wellbeing and develops green potential and toward achieving energy efficiency in energy sector of Malaysia by preserving environment as well as reducing carbon emission.

    Potatoes are one of the commodities with the highest loss shares along the entire supply chain. In the present study, we analyzed six potential loss reduction scenarios concerning their environmental-socio-economic sustainability compared with the current situation by using the "SustainOS" methodology. For this purpose, life cycle assessments, full-cost calculations and an online consumer survey were conducted. Environmental improvements through loss reduction were rather small and did not cross limits of significance, but the socio-economic performance of the entire supply chain can be improved considerably. Pearson correlation coefficients and linear regression analyses were used to predict the influence of specific subjective items like the intention to avoid food loss, knowledge related to food loss and consumers' price sensitivity on the assigned preference. Results show that perceived risks, perceived inconvenience and the general acceptance of loss-reducing instruments influence consumers' preferences. Altogether, only three out of six tested scenarios seem realistic: selling unwashed potatoes in a lightproof box, selling unpacked potatoes, and improved quality sorting at farms. For two of the other scenarios, consumers significantly indicated their refusal even if losses decreased considerably, whereas the sixth scenario was unfavorable from a socio-economic perspective.

    Background Dengue is a major mosquito-borne viral disease and an important public health problem. Identifying which factors are important determinants in the risk of dengue infection is critical in supporting and guiding preventive measures. In South-East Asia, half of all reported fatal infections are recorded in Indonesia, yet little is known about the epidemiology of dengue in this country. Methodology/Principal findings Hospital-reported dengue cases in Banyumas regency, Central Java were examined to build Bayesian spatial and spatio-temporal models assessing the influence of climatic, demographic and socio-economic factors on the risk of dengue infection. A socio-economic factor linking employment type and economic status was the most influential on the risk of dengue infection in the Regency. Other factors such as access to healthcare facilities and night-time temperature were also found to be associated with higher risk of reported dengue infection but had limited explanatory power. Conclusions/Significance Our data suggest that dengue infections are triggered by indoor transmission events linked to socio-economic factors (employment type, economic status). Preventive measures in this area should therefore target also specific environments such as schools and work areas to attempt and reduce dengue burden in this community. Although our analysis did not account for factors such as variations in immunity which need further investigation, this study can advise preventive measures in areas with similar patterns of reported dengue cases and environment.

Immature pigeons began the post-juvenal molt at 35 days which continued up to 340 days. The only 3 plumage characters useful for identification and estimation of age were presence of juvenal lesser, middle, and greater secondary coverts, juvenal secondaries, and juvenal primaries. While juvenal primaries were still present, hatching dates could be estimated up to 252 days (N = 84). Secondary feather presence and molt stage could be used to identify juvenile pigeons for more than 340 days (N = 24). Using coloration of the crown and breast feathers, 96 percent of the immature pigeons examined (106 of 110) at 80 days of age were classified accurately as to sex.

    In South Africa, dating violence is known to be widespread among adolescents, and is therefore a major public health issue because of its association with sexual risk behaviours. The objective of the study was to examine the relationship between dating violence and self-efficacy for delayed sex among school-going adolescents in Cape Town, South Africa. The study is based on analyses of data from a school-based health education programme targeting sexual and reproductive health issues.The study involved 3,655 school-going adolescents aged between 12 and 17 in Cape Town, South Africa. The data was collected by means of a self-administered questionnaire composed of 153 items on sexual and reproductive health, dating violence as well as sociodemographic characteristics. The results indicated that males showed a higher percentage of both dating violence victimization and perpetration, as compared to females. It was also found that adolescents from lower socio-economic backgrounds were more likely to be the victims of dating violence as compared to those from a higher socio-economic background. Female learners showed higher levels of self-efficacy for delayed sex than their male counterparts. Although the result revealed that there was a significant association between self-efficacy for delayed sex and socio-economic status, this link decreased with age. It is concluded that educational programmes aimed solely at improving self-efficacy for delayed sex is insufficient. Such programmes must also aim at preventing dating violence and equipping adolescents with the skills to negotiate their way out of dating violence.

    Recently, it has been demonstrated that men outperform women in spatial analysis of complex auditory scenes (Zündorf et al., 2011). The present study investigated the relation between the effects of ageing and sex on the spatial segregation of concurrent sounds in younger and middle-aged adults. The experimental design allowed simultaneous presentation of target and distractor sound sources at different locations. The resulting spatial "pulling" effect (that is, the bias of target localization toward that of the distractor) was used as a measure of performance. The pulling effect was stronger in middle-aged than younger subjects, and female than male subjects. This indicates lower performance of the middle-aged women in the sensory and attentional mechanisms extracting spatial information about the acoustic event of interest from the auditory scene than both younger and male subjects. Moreover, age-specific differences were most prominent for conditions with targets in right hemispace and distractors in left hemispace, suggesting bilateral asymmetries underlying the effect of ageing.

    The sex-age-kill (SAK) model is widely used to estimate abundance of harvested large mammals, including white-tailed deer (Odocoileus virginianus). Despite a long history of use, few formal evaluations of SAK performance exist. We investigated how violations of the stable age distribution and stationary population assumption, changes to male or female harvest, stochastic effects (i.e., random fluctuations in recruitment and survival), and sampling efforts influenced SAK estimation. When the simulated population had a stable age distribution and λ > 1, the SAK model underestimated abundance. Conversely, when λ < 1, the SAK overestimated abundance. When changes to male harvest were introduced, SAK estimates were opposite the true population trend. In contrast, SAK estimates were robust to changes in female harvest rates. Stochastic effects caused SAK estimates to fluctuate about their equilibrium abundance, but the effect dampened as the size of the surveyed population increased. When we considered both stochastic effects and sampling error at a deer management unit scale the resultant abundance estimates were within ±121.9% of the true population level 95% of the time. These combined results demonstrate extreme sensitivity to model violations and scale of analysis. Without changes to model formulation, the SAK model will be biased when λ ≠ 1. Furthermore, any factor that alters the male harvest rate, such as changes to regulations or changes in hunter attitudes, will bias population estimates. Sex-age-kill estimates may be precise at large spatial scales, such as the state level, but less so at the individual management unit level. Alternative models, such as statistical age-at-harvest models, which require similar data types, might allow for more robust, broad-scale demographic assessments.

    Long term management of water resources is challenging for decision makers given the range of uncertainties that exist. Such uncertainties are a function of long term drivers of change, such as climate, environmental loadings, demography, land use and other socio economic drivers. Impacts of climate change on frequency of extreme events such as drought make it a serious threat to water resources and water security. The release of probabilistic climate information, such as the UKCP09 scenarios, provides improved understanding of some uncertainties in climate models. This has motivated a more rigorous approach to dealing with other uncertainties in order to understand the sensitivity of investment decisions to future uncertainty and identify adaptation options that are as far as possible robust. We have developed and coupled a system of models that includes a weather generator, simulations of catchment hydrology, demand for water and the water resource system. This integrated model has been applied in the Thames catchment which supplies the city of London, UK. This region is one of the driest in the UK and hence sensitive to water availability. In addition, it is one of the fastest growing parts of the UK and plays an important economic role. Key uncertainties in long term water resources in the Thames catchment, many of which result from earth system processes, are identified and quantified. The implications of these uncertainties are explored using a combination of uncertainty analysis and sensitivity testing. The analysis shows considerable uncertainty in future rainfall, river flow and consequently water resource. For example, results indicate that by the 2050s, low flow (Q95) in the Thames catchment will range from -44 to +9% compared with the control scenario (1970s). Consequently, by the 2050s the average number of drought days are expected to increase 4-6 times relative to the 1970s. Uncertainties associated with urban growth increase these risks further

    Carps are the mainstay of Indian aquaculture, contributing over 90% to the total fish production, which was estimated to be 1.77 million metric tonnes in 1996. Carp culture has a great potential for waste utilization and thus for pollution abatement. Many wastes such as cow, poultry, pig, duck, goat, and sheep excreta, biogas slurry, effluents from different kinds of factories/industries have been efficiently used for enhancing the productivity of natural food of carps and related species. Besides, several organic wastes/byproducts such as plant products, wastes from animal husbandry, and industrial by-products have been used as carp feed ingredients to lower the cost of supplementary feeding. However, to ensure the continued expansion of fish ponds and the pollution control, there must be a market for the fish (carps) produced in these ponds. The carps have, however, a low market value due to the presence of intra-muscular bones, which reduces their consumer acceptability. Thus, a need was felt to develop some boneless convenience products for enhancing the consumer acceptability of the carps. Efforts were made to prepare three value-added fish products, namely fish patty, fish finger and fish salad from carp flesh and were compared with a reference product ('fish pakoura'). Sensory evaluation of these products gave highly encouraging results. The methods of preparation of these products were transferred to some progressive farmers of the region who prepared and sold these products at very attractive prices. Carp processing has a great potential for the establishment of a fish ancillary industry and thus for boosting the production of these species. In Punjab alone, there is a potential of consuming 32,448 metric tonnes per annum of such value-added products (which would require 54,080 metric tonnes of raw fish). The development of value-added products has a significant role in raising the socio-economic status of the people associated with carp culture. The

    Urban expansion accompanied by losses of vegetated spaces and their ecological services raises significant concerns about the future of humans in metropolitan "habitats". Despite recent growth of urban studies globally, it is still not well understood how environmental effects of urbanization vary with the rate and socioeconomic context of development. Our study hypothesized that with urban development, spatial patterns of surface thermal properties and green plant cover would shift towards higher occurrence of relatively warmer and less vegetated spaces such as built-up areas, followed by losses of greener and cooler areas such as urban forests, and that these shifts would be more pronounced with higher rate of economic and/or population growth. To test these ideas, we compared 1992-2011 changes in remotely sensed patterns of green vegetation and surface temperature in three example cities that experienced peripheral growth under contrasting socio-economic context - Dallas, TX, USA, Beijing, China and Kyiv, Ukraine. To assess their transformation, we proposed a metric of thermal-vegetation angle (TVA) estimated from per-pixel proxies of vegetation greenness and surface temperature from Landsat satellite data and examined changes in TVA distributions within each city's core and two decadal zones of peripheral sprawl delineated from nighttime satellite data. We found that higher economic and population growth were coupled with more pronounced changes in TVA distributions, and more urbanized zones often exhibited higher frequencies of warmer, less green than average TVA values with novel patterns such as "cooler" clusters of building shadows. Although greener and cooler spaces generally diminished with development, they remained relatively prevalent in low-density residential areas of Dallas and peripheral zones of Kyiv with exurban subsistence farming. Overall, results indicate that the effects of modified green space and thermal patterns within growing cities

This integrated model allows to quantitatively explore possible trajectories of future evolution of the hydropower systems under the combined effect of climate and socio-economic drivers. In a multi-objective perspective, the model can test how different hydropower operation strategies perform in terms of power production, reliability and flexibility of supply, profitability of operation, and ecosystem conservation. This contribution presents the methodological framework designed to formulate the integrated model, its expected outcomes, and some preliminary results on a pilot study.

    Background Both antenatal and postpartum depression have adverse, lasting effects on maternal and child well-being. Socio-economically disadvantaged women are at increased risk for perinatal depression and have experienced difficulty accessing evidence-based depression care. The authors evaluated whether “MOMCare,”a culturally relevant, collaborative care intervention,providing a choice of brief interpersonal psychotherapy and/or antidepressants,is associated with improved quality of care and depressive outcomes compared to public health Maternity Support Services(MSS-Plus). Methods A randomized multi-site controlled trial with blinded outcome assessment was conducted in the Seattle-King County Public Health System. From January 2010-July 2012, pregnant women were recruited who met criteria for probable major depression and/or dysthymia, English-speaking,had telephone access, and ≥18-years-old. The primary outcome was depression severity at 3-,6-,12-,18-month postbaseline assessments; secondary outcomes included functional improvement, PTSD severity, depression response and remission, and quality of depression care. Results All participants were on Medicaid and 27-years-old on average; 58% were non-white; 71% were unmarried; and 65% had probable PTSD. From before birth to 18-months-postbaseline, MOMC are (n=83) compared to MSS-Plus participants (n=85) attained significantly higher rates of depression remission (Wald'sχ2=3.67,df=1,p=.05), lower levels of depression severity (Wald's χ2=6.09, df=1,p=.01) and PTSD severity (Wald'sχ2=4.61,df=1,p=.04), and had a greater likelihood of receiving ≥4 mental health visits (Wald'sχ2=58.23,df=1,p<.0001) and of adhering to anti-depressants in the prior month (Wald'sχ2=10.00,df =1,p<.01). Conclusion Compared to MSS-Plus, MOMCare showed significant improvement in quality of care, depression severity and remission rates from before birth to 18-months-postbaseline for socioeconomically disadvantaged women.

    "This paper focuses on the effects of age at marriage and the sex-ratio on patterns of ethnic homogamy among Israeli women. We hypothesize that later marriages are more likely than early marriages to be heterogamous as the 'marriage market' shifts from school to the work-place. By the same token, when facing severe marriage squeezes women will be forced to out-marry. Employing data from the 1983 census, we model mate selection of women from Afro-Asian and Euro-American origin in various birth-cohorts. The results do not fully support our hypotheses: we find that in and of itself, age at marriage does not enhance ethnic heterogamy."

    It has been held for a long time that the young are more susceptible than adults to the induction of cancer by radiation. The data in support of that contention are accumulating especially from human studies. In an exposed population a significant fraction of the total population risk may be attributed to the risk associated with those who were young at the time of exposure. Since cancer may not appear for decades after exposure estimates of risk may require models for projecting the lifetime risk. Two such models, additive or absolute risk and multiplicative or relative risk have been used. The appropriateness of the latter model is supported by the finding in mice of a positive relationship between natural incidence and the susceptibility for induction by radiation of solid cancer. The choice of model for leukemias is not clear cut. The incidence of cancer increases with age, but the susceptibility for induction decreases. The incidence of cancers increases to a peak and then begins to decline at different ages, dependent on the type of cancer. Sex-dependent differences in both the natural incidence and the susceptibility for induction of cancer are not restricted to sex organs. For example, the susceptibility for the induction by radiation for myeloid leukemia is greater in males than females, whereas in the case of thymic lymphoma it is vice versa. 25 refs., 5 figs., 3 tabs.

  18. Socio-economic influences on gender inequalities in child health in rural Bangladesh.

    During February 1989-June 1990 in Bangladesh, local field assistants collected data on 1366 children 2-6 years old, attending maternal and child health clinics operated by a nongovernmental organization, and living in 13 villages in Jamalpur District situated on the banks of the Jamuna River. The field assistants made home visits to record child morbidity every 2 weeks and to measure child height and weight once a month. During January-April 1989, this area suffered from extensive food shortages due to a prolonged drought and one of the worst floods recorded in Bangladesh. Gender bias was not apparent in farming and trading/employee households. In landless households (i.e., fathers' occupation was laborer), girls were significantly shorter and less heavy than boys (p 0.001), however. During a natural disaster, fathers' occupation significantly interacted with sex (p 0.05). Specifically, children who were both female and living in a landless household were more likely to have poor nutritional status than children who were female and living in a farming or trading/employee household and children who were male and living in a landless household. This interaction was not apparent as local conditions improved. Over the 16 months following the natural disaster, landless girls grew significantly more in height-for-age and weight-for-age than landless boys (p 0.001). In other words, these girls experienced more catch-up growth than the boys. At the end of the study, nutritional status varied only according to socioeconomic status but not according to gender. These findings suggest that gender bias within this population depends on changes in food availability and the rural economy. Thus, child nutrition programs should target landless girls, who are at highest risk of gender discrimination and malnutrition during economic adversity.

    Cancer diagnosis at an early stage increases the chance of curative treatment and of survival. It has been suggested that delays on the pathway from first symptom to diagnosis and treatment may be socio-economically patterned, and contribute to socio-economic differences in receipt of treatment and in cancer survival. This review aimed to assess the published evidence for socio-economic inequalities in stage at diagnosis of lung cancer, and in the length of time spent on the lung cancer pathway. MEDLINE, EMBASE and CINAHL databases were searched to locate cohort studies of adults with a primary diagnosis of lung cancer, where the outcome was stage at diagnosis or the length of time spent within an interval on the care pathway, or a suitable proxy measure, analysed according to a measure of socio-economic position. Meta-analysis was undertaken when there were studies available with suitable data. Of the 461 records screened, 39 papers were included in the review (20 from the UK) and seven in a final meta-analysis for stage at diagnosis. There was no evidence of socio-economic inequalities in late stage at diagnosis in the most, compared with the least, deprived group (OR=1.04, 95% CI=0.92 to 1.19). No socio-economic inequalities in the patient interval or in time from diagnosis to treatment were found. Socio-economic inequalities in stage at diagnosis are thought to be an important explanatory factor for survival inequalities in cancer. However, socio-economic inequalities in stage at diagnosis were not found in a meta-analysis for lung cancer.

    Within the last decades severe flooding events occurred in many parts of Europe. Especially in 2002, Upper Austria was seriously affected. Beside the natural variability of precipitation events the increase of losses is strongly connected with socio-economic developments. Especially the increase of settlement areas and the specific values of such modern settlement areas in flood prone areas induced this increase of losses. The presented case study was initiated to analyse different consequences of the currently observed socio-economic trend and further socio-economic projections within the watershed of the so-called Ottnanger Redl in Upper Austria, a watershed which was affected by the event in 2002. The temporal dimension of this change in damage potential is analysed for the 1990s, current conditions and future scenarios (Statistics Austria). Beside the socio-economic development the common structural vulnerability but also the positive effect of legislation and standards concerning flood-adapted constructions are considered. The hydrological-hydraulic is realized based on a scaled scenario approach. Therefore, documented precipitation events at rain gauges are considered for precipitation run-off simulations. To include further events the gauged events are scalled in their intensity. The hydrological loads of these scenarios are considered within different 2D hydraulic simulations; representation of past, current and future settlement structure. Based on the current settlement structure and its transfer in an asset value database, the past structure of the 1990s is reconstructed with remote sensing methods. The future structure (different pragmatic scenarios) in contrast is estimated on the basis of the current situation, socio-economic projections of Statistics Austria, land-use planes and local development concepts of the individual communities and in cooperation with the Regional Government of Upper Austria.

    Methods to determine the sex and age of Apapane (Himatione sanguinea) and Iiwi (Vestiaria coccinea) were developed on the basis of 189 museum specimens and 91 live birds captured in mist nets on the Island of Hawaii (USA). Both species retain all juvenal primaries and some juvenal secondaries and body feathers after the first prebasic molt and attain full adult plumage after the second prebasic molt. Apapane in their first basic plumage retain some buff-edged juvenal secondaries (particularly secondaries five and six) and sometimes retain a few gray-brown feathers on the head. The first basic plumage of Iiwi is characterized by secondaries 6-9 being longer and darker than secondaries 1-4 and the presence of a few yellowish juvenal body feathers with black spots at the tips. Adult male Apapane and Iiwi have longer wing, tail, exposed culmen, culmen and tarso-metatarsus lengths than females. Linear discriminant functions are presented to sex adult Apapane and Iiwi from lengths of their wing chord and exposed culmen.

    Socio-emotional well-being, established through nurturing relationships and community experiences, enables children and adults to evolve into caring, nonviolent, emotionally healthy citizens. This paper analyses purposefully selected development texts, authored by three prominent contributors of socio-economic development discourse: the United Nations, the World Bank and the International Monetary Fund. On the basis of a socio-emotional capacity development framework that draws from research produced in the areas of developmental psychology, biopsychology, brain research and peace psychology, the study evaluates texts' tendencies to make socio-emotionally conducive -- or neglectful -- programme recommendations. The study finds that United Nations conference reports indirectly acknowledge the relevance for socio-emotional enablement and protection, in the context of discussions related to human and children's rights, education or women's empowerment. However, they only marginally discuss the need to foster socio-emotional well-being as a human capacity development rationale per se. The International Monetary Fund, while acknowledging responsibility for the social conduciveness of macro-economic development interventions, does not address socio-emotional capacity development issues. The World Bank's strategic plan and other strategy papers touch on issues of socio-emotional capacity development only tangentially. The study concludes that the discourse communities authoring the selected development texts largely ignore the question of socio-emotional capacity development. Their discourses 'background' discussions about the kind and nature of social structures necessary for nurturing socio-emotional enablement. Developmental psychologists are challenged to 'infect' socio-economic development discourse by calling for the effective integration of the theme of socio-emotional well-being into socio-economic development publications.

    Background: Despite significant reduction in global disease prevalence, leprosy still has a high rate of disability while its determinants are unfair and many of them are amendable. The objective of this study was to measure inequality of disability in leprosy in Iran. Methods: This was a cross-sectional study (2006-2007) on all living people affected by leprosy registered in W. Azerbaijan province health center, Western North of Iran. The outcome of the study was the socio-economic inequality considering presence or absence of grade 2 disability (G2D) based on the WHO classifications. An extended concentration index decomposition approach was used for analysis. Results: Among 452 cases, 65.3% were male and 67% were affected by the multi bacillary type. Overall G2D was 65.3%. The estimated Concentration Index was −0.0782, showing presence of pro-poor socio-economic inequality of G2D, while extended CI estimation (ѵ = 5) was −0.163. Achievement index with coefficient (ѵ = 5) revealed that G2D mean was 16% more than classic mean in the poorest group. The result of decomposition of the existing inequality revealed that, some of the determinants such as receiving mono-therapy, education, urbanization, and bacillus calmette guerin (BCG) vaccination had shared contribution (67.4%, 61.8%, 59.2%, and 57.5% respectively). Conclusions: This study provided new perspective for the health system to leprosy control considering the significant gap between rich and poor (inequality) regarding G2D disability, and its effective elements in socio-economic strata. Some effective actions can be considered to reduce the scale of existing inequality. PMID:24829728

    Cooperation between the social and natural sciences has become essential in order to encompass all the dimensions of coastal zone management. Socio-economic approaches are increasingly recommended to complement integrated assessment in support of these initiatives. A systematic review of the academic literature was carried out in order to analyze the main types of socio-economic assessments used to inform the coastal zone management process as well as their effectiveness. A corpus of 1682 articles published between 1992 and 2011 was identified by means of the representative coverage approach, from which 170 were selected by applying inclusion/exclusion criteria and then classified using a content analysis methodology. The percentage of articles that mention the use of socio-economic assessment in support of coastal zone management initiatives is increasing but remains relatively low. The review examines the links between the issues addressed by integrated assessments and the chosen analytical frameworks as well as the various economic assessment methods which are used in the successive steps of the coastal zone management process. The results show that i) analytical frameworks such as 'risk and vulnerability', 'DPSIR', 'valuation', 'ecosystem services' and 'preferences' are likely to lead to effective integration of social sciences in coastal zone management research while 'integration', 'sustainability' and 'participation' remain difficult to operationalize, ii) risk assessments are insufficiently implemented in developing countries, and iii) indicator systems in support of multi-criteria analyses could be used during more stages of the coastal zone management process. Finally, it is suggested that improved collaboration between science and management would require that scientists currently involved in coastal zone management processes further educate themselves in integrated assessment approaches and participatory methodologies.

    Why do some countries, regions and schools have more bullying than others? What socio-economic, socio-political and other larger contextual factors predict school bullying? These open questions inspired this study with 53.316 5th- and 9th-grade students (5% of the national student population in these grades), from 1,000 schools in Colombia. Students completed a national test of citizenship competencies, which included questions about bullying and about families, neighborhoods and their own socio-emotional competencies. We combined these data with community violence and socio-economic conditions of all Colombian municipalities, which allowed us to conduct multilevel analyses to identify municipality- and school-level variables predicting school bullying. Most variance was found at the school level. Higher levels of school bullying were related to more males in the schools, lower levels of empathy, more authoritarian and violent families, higher levels of community violence, better socio-economic conditions, hostile attributional biases and more beliefs supporting aggression. These results might reflect student, classroom and school contributions because student-level variables were aggregated at the school level. Although in small portions, violence from the decades-old-armed conflict among guerrillas, paramilitaries and governmental forces predicted school bullying at the municipal level for 5th graders. For 9th graders, inequality in land ownership predicted school bullying. Neither poverty, nor population density or homicide rates contributed to explaining bullying. These results may help us advance toward understanding how the larger context relates to school bullying, and what socio-emotional competencies may help us prevent the negative effects of a violent and unequal environment.

    Over the past decade, the effects of AIDS-related parental death on children's socio-economic, educational and psychological well-being have become apparent. Most studies, however, have compared the plight of so-called AIDS orphans with non-orphaned children only. Consequently, such study designs are unable to establish if the AIDS-related cause of death of the parents confers effects additional to those of parent-bereavement. We therefore conducted a cross-sectional survey to assess the psychological well-being and socio-economic hardship among 140 non-orphaned children, 133 children orphaned by causes other than AIDS (O) and 124 children orphaned by AIDS (O-A) in Conakry, N'Zerekore and the villages around N'Zerekore, Guinea. Multi-way analysis of variance and multiple (ordinal) logistic regression models were applied to measure the association between the orphan status and psychological well-being, school attendance, economic activities, frequency of going to bed hungry and sleeping commodity. After adjustment for confounding factors, the psychological well-being score (PWS) was significantly lower among AIDS-orphaned children than among O (P<0.001). Additionally, AIDS-orphaned children were more likely to be engaged in economic activities (adjusted odds ratio (AOR) = 3.04; 95% CI: 1.45-6.36) and to go to bed hungry on a daily basis (AOR = 2.73; 95% CI: 1.24-6.02) than other orphans. The differences in school attendance and the proportion of children with a bed or couch to sleep between AIDS-orphaned children and O were not statistically significant. This situation calls for sustainable and holistic approaches to ensure the psychological and socio-economic stability of AIDS orphans and other vulnerable children.

    Neuroscientific and psychological research on moral development has until now developed independently, referring to distinct theoretical models, contents, and methods. In particular, the influence of socio-economic and cultural factors on morality has been broadly investigated by psychologists but as yet has not been investigated by neuroscientists. The value of bridging these two areas both theoretically and methodologically has, however, been suggested. This study aims at providing a first connection between neuroscientific and psychological literature on morality by investigating whether socio-economic dimensions, i.e., living socio-geographic/economic area, immigrant status and socio-economic status (SES), affect moral reasoning as operationalized in moral domain theory (a seminal approach in psychological studies on morality) and in Greene et al. (2001) perspective (one of the main approaches in neuroethics research). Participants were 81 primary school (M = 8.98 years; SD = 0.39), 72 middle school (M = 12.14 years; SD = 0.61), and 73 high school (M = 15.10 years; SD = 0.38) students from rural and urban areas. Participants' immigrant status (native vs. immigrant) and family SES level were recorded. Moral reasoning was assessed by means of a series of personal and impersonal dilemmas based on Greene et al. (2001) neuroimaging experiment and a series of moral and socio-conventional rule dilemmas based on the moral domain theory. Living socio-geographic/economic area, immigrant status and SES mainly affected evaluations of moral and, to a higher extent, socio-conventional dilemmas, but had no impact on judgment of personal and impersonal dilemmas. Results are mainly discussed from the angle of possible theoretical links and suggestions emerging for studies on moral reasoning in the frameworks of neuroscience and psychology. PMID:23015787

    The impacts of climate and associated socio-economic changes on water availability, including supply and demand, quality, and storage volume, were evaluated for the Vale do Gaio reservoir in southern Portugal, located in a dry Mediterranean climate and already under drought stress. The SWAT model was applied with 6 scenarios for 2071-2100, involving two storylines (A1B and B1) with individual changes in climate (-9% rainfall, increasing in winter by +28 to +30%), socio-economic conditions (an increase in irrigation demand by 11%, and a replacement of cereals and pastures by sunflower), and a combination of both. Most future scenarios resulted in lower water availability, due to lower supply (-19 to -27%) combined with higher irrigation demand (+3 to +21%). This resulted in more years with limited irrigation supplies (presently: 28%; scenarios: 37 to 43%), although limitations were mitigated by lower losses to excess discharge. Land-use changes also decreased quality by increasing P concentrations (+29 to +93%). Impacts were more severe in scenario A1B than in B1, and in combined changes than in climate or socio-economic changes only. Water availability was resilient to climate change, as impacts led only to a moderate aggravation of present-day conditions. Lower future water availability could be addressed by supply and demand management strategies and, in the most extreme scenario, by water transfers from regional water reserves; water quality issues could be addressed through land-use policies. Results also highlighted the importance of taking the characteristics of water supply systems into account when designing adaptation measures for future changes.

    Background: Although needle and syringe sharing is one of the main routs of transmission of HIV in several countries in the middle east, very little is known about how socio-economic status of injecting drug users (IDUs) is linked to the receptive syringe sharing behaviors in these countries. Aim: To study socio-economic correlates of receptive needle and syringe sharing among IDUs in Iran. Methods: The study used data from the Unhide Risk Study, a national survey of IDUs. This study sampled 636 IDUs (91% male) via snowball sampling from eight provinces in Iran in 2009. Socio-demographic and drug use characteristics were collected. We used a logistic regression to determine factors associated with receptive needle and syringe sharing during the past 6 months. Results: From 636 IDUs enrolled in this study, 68% (n = 434) reported receptive needle and syringe sharing behaviors in the past 6 months. Odds of receptive needle and syringe sharing in the past 6 months was lower among IDUs who were male [odds ratios (OR) = 0.29, 95% confidence interval (CI) = 0.12–0.70], had higher education (OR = 0.74, 95% CI = 0.64–0.86) but higher among those who were unemployed (OR = 4.05, 95% CI = 1.50–10.94), and were single (OR = 1.47, 95% CI = 1.02–2.11). Conclusion: This study presented factors associated with risk of receptive needle and syringe sharing among Iranian IDUs. This information may be used for HIV prevention and harm reduction purposes. Socio-economic status of Iranian IDUs may be closely linked to high-risk injecting behaviors among them. PMID:25852577

    The approaches for vulnerability and risk assessment have found different and often contrasting solutions by various schools of thought. The two most prominent communities in this field are: climate change adaptation (CCA), and disaster risk reduction (DRR). Although those communities have usually in common the aim of reducing socio-economic vulnerability and risk to natural hazards, they have usually referred to different definitions and conceptualizations. For example, the DRR community has always driven more emphasis on the concept of risk and vulnerability is considered as a physical/environmental input for the quantification of risk, while the CCA research stream, mainly under the auspices of the Intergovernmental Panel on Climate Change (IPCC), considered vulnerability as an output deriving from social conditions and processes such as adaptation or maladaptation. Recently, with the publication of the IPCC Special Report on extreme events and disasters (IPCC-SREX), the notions of vulnerability and risk are somehow integrated in order to jointly consider both climate change adaptation and disaster risk management. The IPCC-SREX indeed is expected to significantly contribute to find common language and methodological approaches across disciplines and, therefore, the opportunity emerges for proposing new operational solutions, consistent with the most recent evolution of concepts and terminology. Based on the development of the IPCC Report, the KULTURisk project developed an operational framework to support integrated assessment and decision support through the combination of contributions from diverse disciplinary knowledge, with emphasis on the social and economic dimensions. KIRAF (KULTURisk Integrated Risk Assessment Framework) is specifically aimed at comprehensively evaluate the benefits of risk mitigation measures with consideration of the dynamic context deriving from the consideration of climatic changes and their effects on natural disasters, within the

  12. Socio-economic Evaluation Of Different Alternatives For Flood Protection Within The Rivierenland-project

    Boot, S. P.; van Ast, J. A.

    The Netherlands have a tradition of protecting land against flooding from the main rivers Rhine, Meuse and Scheldt by means of an extensive system of dikes. In recent years, however, this approach to protection has been increasingly questioned with re- gard to its sustainability and cost-effectiveness. The argument is that although the continued elevation of dikes may be technically feasible, there are several disadvan- tages to this approach. Firstly, a vast network of dikes requires a very high degree of organisation of water management, in which mistakes can not be afforded. Such a high degree of organisation may not always be maintainable in the future, due to changed economic or political circumstances. Secondly, it may not be the most cost- effective system for maintaining safety in the long term. Thirdly, it may not be the most desirable approach in terms of sustainability. One of the alternatives to contin- ued dike-elevation is the concept 'room for the river' ('ruimte voor de rivier'), which aims to give more space to rivers in the horizontal in stead of the vertical dimen- sion. This approach would reduce the risk of flooding, defined as the product of the probability and the consequences of flooding. In order to explore the long term con- sequences of both alternatives ('dike elevation' and 'room for the river'), the ministry of Verkeer en Waterstaat (Public Works, Transport and Water Management) started the 'Rivierenland'-project. The comparison of the alternatives mentioned was based on a fictitious project to adjust a region of The Netherlands, between the rivers Rhine and Meuse, to the concept of 'room for water'. The consequence of this adjustment would be that safety within that region would no longer be safeguarded by dikes, but by adjusting daily life to the 'demands of the water'. Part of the 'Rivierenland'-project was an analysis of the socio-economic costs and benefits of the alternative approaches. Within this analysis, a study was performed

    The current land cover of Ukraine is very heterogeneous. While on average forest covers 15.9% of its land, substantial part of the country is basically forestless. The agricultural potential of Ukraine is high. However, in spite of the fact that 68% of the arable land in Ukraine consists of the famous Ukrainian black soils (chernozems), the quality of the country's arable land (69.5% of the total land) is not satisfactory. The country has the highest over the globe share of the tilled land (~80% of the agricultural land in the country) and processes of soil erosion impact about one third of arable land. Air pollution, soil and water contamination are widespread. Substantial problems are generated by the Chernobyl disaster. Overall, about half of the country is in the critical and pre-critical ecological situation. Climatic predictions suppose that the country will live in much warmer and drier climate by end of this century. Taking into account that major pat of Ukraine lies in the xeric belt, the expected climatic change generates divers risks for both environment and vegetation ecosystems of the country, particularly for forests and agriculture. The presentation considers the role of forests and trees outside of forests in transition to integrated ecosystem management and sustainable structure of landscapes within two scenarios of socio-economic development for the next 20 yeas. The "business-as-usual" scenario prolongs tendencies of dynamics of the land-use and forest sectors during the last 20 years. This scenario leads to further deterioration of quality of land and environment in Ukraine. The "progressive" scenario is considered as a crucial initial step of adaptation to climatic change and includes a system of pressing measures which are needed to decrease destructive processes that are observed at the landscape level. It is shown that it would require development of 1.62 M ha of protective forests including 0.62 M ha on unstable elements of landscapes

    During the course of serious discussion, an unexpected interruption may induce forgetting of the original topic of a conversation. Sex, age, and sex hormone levels may affect frequency and extension of forgetting. In a list-method directed forgetting paradigm, subjects have to learn two word lists. After learning list 1, subjects receive either a forget or a remember list 1 cue. When the participants had learned list 2 and completed a distraction task, they were asked to write down as many recalled items as possible, starting either with list 1 or list 2 items. In the present study, 96 naturally cycling women, 60 oral contraceptive users, 56 postmenopausal women, and 41 young men were assigned to one of these different experimental conditions. Forget-cued young subjects recall fewer list 1 items (list 1 forgetting) but more list 2 items (list 2 enhancement) compared with remember-cued subjects. However, forget-cued postmenopausal women showed reduced list 1 forgetting but enhanced list 2 retention. Remember-cued naturally cycling women recalled more list 1 items than oral contraceptive users, young men, and postmenopausal women. In forget-cued follicular women, salivary progesterone correlated positively with recalled list 2 items. Salivary 17β-estradiol did not correlate with recalled list 1 or list 2 items in either remember- or forget-cued young women. However, salivary 17β-estradiol correlated with item recall in remember-cued postmenopausal women. Our findings suggest that sex hormones do not globally modulate verbal memory or forgetting, but selectively affect cue-specific processing. © 2016 Wiley Periodicals, Inc.

    On a sample of n = 25,346 individuals from Vienna (10,855 males, 14,491 females) the iris pigmentation has been typed by the author. In this sample 65 cases of different types of heterochromia were found. The frequency of the occurrence of the different types of this anomaly could be calculated for the first time. Neglecting age, sex, and type of heterochromia the total frequency amounts to 0.256 (males: 0.157; females: 0.37) %. The variants of heterochromia very from cases of total heterochromia to those of various size; in addition to it a number of special types could be observed. The localization of the heterochrome parts of the iris shows certain variations; mostly, however, it is seen in the lower half of the iris. The nasal part is concerned in only one case; the temporal region never. Thus, the partial heterochromia is characteristic by a marked dependency of its localization. The colour of heterochromia varies from 2 a-14 according to the Martin-Schultz standard set of coloured eyes. However, No. 9 (ca. 50%) and No. 7 (ca. 20%) were the most frequent colours. The age variations are considerable. 5/6 of all heterochromias were found between the age from 2-19 years. Finally, a marked sexual dimorphism was observed, as in females heterochromia is much more frequent than in males.

    Forty healthy men and women 19 to 80 years old received a single 10 mg oral dose of the 7-nitro benzodiazepine nitrazepam. Nitrazepam plasma concentrations were measured during the next 72 hours. Among men, the elderly had a larger volume of distribution (Varea) than did younger subjects (1.96 vs. 1.63 L/kg; P less than 0.05); because clearance did not change with age (0.84 vs. 0.95 ml/min/kg), the prolonged t1/2 in elderly men (28 vs. 20 hours; P less than 0.01) was a result of the larger Varea. Elderly and young women did not differ in nitrazepam Varea (2.58 vs. 2.55 L/kg), t1/2 (26 vs. 27 hours), or total clearance (1.19 vs. 1.09 ml/min/kg). The nitrazepam free fraction in plasma (18% to 19% unbound) was not related to age or sex. Among 18 subjects who also received antipyrine, the clearance of nitrazepam and antipyrine were not correlated (r = 0.23). Thus age minimally influences nitrazepam clearance (accomplished mainly by nitroreduction), which in turn is not significantly related to antipyrine oxidizing capacity.

    Previous studies analysing personality and cannabis use in adult samples suggest that cannabis users show significant higher levels of impulsivity, sensation seeking and schizotypy. However, there are few studies exploring this relationship in adolescence using psychobiological models of personality. Given the relevance of identifying individual differences that lead adolescents to early cannabis use to prevent future health problems, the present study aimed to explore the relationship between age, sex, personality and early cannabis use using a psychobiological model of personality in a sample of 415 students (51.8% boys) from 12 to 18 years. Chi(2) tests showed significant higher prevalence of cannabis use in boys and in the group aged 15-18 years. Multiple analysis of variance showed significant higher scores in psychoticism, sensation seeking and in all its subscales in cannabis users group, while an interaction with age was found for extraversion and neuroticism: cannabis users scored higher than non-users in the youngest group (12-14 years) but lower in the oldest group in both dimensions. Finally, regression analysis showed that narrower traits of sensation seeking (experience seeking and disinhibition) were the most associated to early cannabis use. Results are discussed in terms of early cannabis users' personality profiles and in terms of the self-medication theory.

    A global water scarcity assessment for the 21st century was conducted under the latest socio-economic scenario for global change studies, namely Shared Socio-economic Pathways (SSPs). SSPs depict five global situations with substantially different socio-economic conditions. In the accompanying paper, a water use scenario compatible with the SSPs was developed. This scenario considers not only quantitative socio-economic factors such as population and electricity production but also qualitative ones such as the degree of technological change and overall environmental consciousness. In this paper, water availability and water scarcity were assessed using a global hydrological model called H08. H08 simulates both the natural water cycle and major human activities such as water abstraction and reservoir operation. It simulates water availability and use at daily time intervals at a spatial resolution of 0.5° × 0.5°. A series of global hydrological simulations were conducted under the SSPs, taking into account different climate policy options and the results of climate models. Water scarcity was assessed using an index termed the Cumulative Abstraction to Demand ratio, which is expressed as the accumulation of daily water abstraction from a river divided by the daily consumption-based potential water demand. This index can be used to express whether renewable water resources are available from rivers when required. The results suggested that by 2071-2100 the population living under severely water-stressed conditions for SSP1-5 will reach 2588-2793 × 106 (39-42% of total population), 3966-4298 × 106 (46-50%), 5334-5643 × 106 (52-55%), 3427-3786 × 106 (40-45%), 3164-3379 × 106 (46-49%) respectively, if climate policies are not adopted. Even in SSP1 (the scenario with least change in water use and climate) global water scarcity increases considerably, as compared to the present-day.

    Central Asia, encompassing the republics of Kazakhstan, Kyrgyz, Uzbekistan, Turkmenistan, Tajikistan and China's western Sinkiang, is a typical arid and semi-arid area. The climate in Central Asia is extreme arid, where summer is hot, cloudless and dry, and winter is moist and relatively warm in the south and cold and dry in the north. Rangeland, accounting for 46% of the entire area, is the main vegetation type in this area. Recent findings showed that climate change had caused unprecedented rangeland degradation in Central Asia over the past 30 years. Socio-economical change and environmental change due to the collapse of Soviet Union also accelerated rangeland degradation. Rangeland degradation adversely further deteriorated the environment. With the development of high resolution remote sensing images, an increasing attention has paid to study rangeland degradation in this area. However, previous investigations based on either Advanced Very High Resolution Radiometer (AVHRR) or Moderate Resolution Imaging Spectroradiometer (MODIS) data, has not integrate multi-resolution satellite data for investigating vegetation change and its response to climatic and socio-economic change . In this paper, we employed 30 years' remote sensing data, including both AVHRR ( 1982-2006) and MODIS (2000-2011) satellite data, and in-situ meteorological and social data (e.g. population, economic, and land use change data), to investigate rangeland degradation in the central Asia. We 1) analyzed the spatial-temporal variations of vegetation changes during the past 30 years, and 2) evaluated the roles of climatic and socio-economic factors as potential causes of observed vegetation changes. The results showed extensive area had statistically significant degradation trends (p<0.05). Precipitation was the main driver of rangeland degradation, while there were relatively weaker relationships between temperature and NDVI, indicating that water deficit largely limited vegetation activity

    The objective of this work is to assess the impacts of climate change and socio economics on agriculture in the Columbia River basin (CRB) in the Pacific Northwest region of the U.S. and a portion of Southwestern Canada. The water resources of the CRB are managed to satisfy multiple objectives including agricultural withdrawal, which is the largest consumptive user of CRB water with 14,000 square kilometers of irrigated area. Agriculture is an important component of the region's economy, with an annual value over 5 billion in Washington State alone. Therefore, the region is relevant for applying a modeling framework that can aid agriculture decision making in the context of a changing climate. To do this, we created an integrated biophysical and socio-economic regional modeling framework that includes human and natural systems. The modeling framework captures the interactions between climate, hydrology, crop growth dynamics, water management and socio economics. The biophysical framework includes a coupled macro-scale physically-based hydrology model (the Variable Infiltration Capacity, VIC model), and crop growth model (CropSyst), as well as a reservoir operations simulation model. Water rights data and instream flow target requirements are also incorporated in the model to simulate the process of curtailment during water shortage. The economics model informs the biophysical model of the short term agricultural producer response to water shortage as well as the long term agricultural producer response to domestic growth and international trade in terms of an altered cropping pattern. The modeling framework was applied over the CRB for the historical period 1976-2006 and compared to a future 30-year period centered on the 2030s. Impacts of climate change on irrigation water availability, crop irrigation demand, frequency of curtailment, and crop yields are quantified and presented. Sensitivity associated with estimates of water availability, irrigation demand, crop

    Car use is associated with substantial health and environmental costs but research in deprived populations indicates that car access may also promote psychosocial well-being within car-oriented environments. This mixed-method (quantitative and qualitative) study examined this issue in a more affluent setting, investigating the socio-economic structure of car commuting in Cambridge, UK. Our analyses involved integrating self-reported questionnaire data from 1142 participants in the Commuting and Health in Cambridge study (collected in 2009) and in-depth interviews with 50 participants (collected 2009-2010). Even in Britain's leading 'cycling city', cars were a key resource in bridging the gap between individuals' desires and their circumstances. This applied both to long-term life goals such as home ownership and to shorter-term challenges such as illness. Yet car commuting was also subject to constraints, with rush hour traffic pushing drivers to start work earlier and with restrictions on, or charges for, workplace parking pushing drivers towards multimodal journeys (e.g. driving to a 'park-and-ride' site then walking). These patterns of car commuting were socio-economically structured in several ways. First, the gradient of housing costs made living near Cambridge more expensive, affecting who could 'afford' to cycle and perhaps making cycling the more salient local marker of Bourdieu's class distinction. Nevertheless, cars were generally affordable in this relatively affluent, highly-educated population, reducing the barrier which distance posed to labour-force participation. Finally, having the option of starting work early required flexible hours, a form of job control which in Britain is more common among higher occupational classes. Following a social model of disability, we conclude that socio-economic advantage can make car-oriented environments less disabling via both greater affluence and greater job control, and in ways manifested across the full socio-economic

    The impacts associated with unconventional oil and gas (UOG) extraction will be cumulative in nature and will most likely occur on a regional scale, highlighting the importance of using strategic decision-making and management tools. Managing possible impacts responsibly is extremely important in a water scarce country such as South Africa, versus countries where more water may be available for UOG extraction activities. This review article explains the possible biophysical and socio-economic impacts associated with UOG extraction within the South African context and how these complex impacts interlink. Relevant policy and governance frameworks to manage these impacts are also highlighted.

    Dietary habits established in early childhood contribute to lifelong dietary pattern and the development of early risk factors for disease in adulthood. Although a large body of epidemiologic data from Western countries show that the dietary pattern of children is influenced by maternal socio-economic and lifestyle characteristics, information on this topic in non-Western countries is absolutely lacking. The present study identified dietary patterns among infants aged 16-24 months, and then examined the influence of maternal socio-economic and lifestyle characteristics on identified dietary patterns. Subjects were 758 Japanese mother-child pairs. Dietary data of infants were collected from the mothers using a questionnaire. Dietary patterns were extracted from the consumption of 15 foods (times week(-1)) by cluster analysis. The following two dietary patterns were identified: 'fruits, vegetables and high-protein foods' (n = 483) and 'confectionaries and sweetened beverages' (n = 275) patterns. After adjustment for all other predictors, maternal educational level, number of infants' siblings and maternal dietary patterns were independently associated with dietary patterns of infants. Infants whose mothers had a higher educational level and the 'rice, fish and vegetables' dietary pattern were less likely to belong to the 'confectionaries and sweetened beverages' pattern, whereas infants whose mothers had a higher number of children and the 'wheat product' dietary pattern were more likely to belong to the 'confectionaries and sweetened beverages' than the 'fruits, vegetables and high-protein foods' pattern. In conclusion, the mother's socio-economic position and dietary patterns were associated with the dietary patterns of infants in the Japanese pairs as observed in the Western populations.

    The study of the socio-economic impacts of natural disasters is still in its infancy. Social scientists have historically regarded natural disasters as exogenous or essentially random perturbations. More recent scholarship treats disaster shocks as endogenous, with pre-existing social, economic and political conditions determining the form and magnitude of disaster impacts. One apparently robust conclusion is that direct economic losses from natural disasters, similar to human losses, are larger (in relative terms) the poorer a country is, yet cross-country regressions show that disasters may accrue economic benefits due to new investments in productive infrastructure, especially if the investment is funded by externally provided capital (Work Bank assistance, private donations, etc) and do not deplete national savings or acquire a debt burden. Some econometric studies also show that the quality of a country's institutions can mitigate the mortality effects of a disaster. The effects on income inequality are such that the poor suffer greater 'asset shocks' and may never recover from a disaster leading to a widening of existing disparities. Natural disasters affect women more adversely than men in terms of life expectancy at birth. On average they kill more women than men or kill women at a younger age than men, and the more so the stronger the disaster. The extent to which women are more likely to die than men or to die at a younger age from the immediate disaster impact or from post-disaster events depends not only on disaster strength itself but also on the socioeconomic status of women in the affected country. Existing research on the economic effects of disasters focus almost exclusively on the impact on economic growth - the growth rate of GDP. GDP however is only a partial indicator of welfare, especially for countries that are in the lower ranks of development status. Very poor communities are typically involved in subsistence level activities or in the

  7. Knowledge and valuation of Andean agroforestry species: the role of sex, age, and migration among members of a rural community in Bolivia

    2013-01-01

    Background Agroforestry is a sustainable land use method with a long tradition in the Bolivian Andes. A better understanding of people’s knowledge and valuation of woody species can help to adjust actor-oriented agroforestry systems. In this case study, carried out in a peasant community of the Bolivian Andes, we aimed at calculating the cultural importance of selected agroforestry species, and at analysing the intracultural variation in the cultural importance and knowledge of plants according to peasants’ sex, age, and migration. Methods Data collection was based on semi-structured interviews and freelisting exercises. Two ethnobotanical indices (Composite Salience, Cultural Importance) were used for calculating the cultural importance of plants. Intracultural variation in the cultural importance and knowledge of plants was detected by using linear and generalised linear (mixed) models. Results and discussion The culturally most important woody species were mainly trees and exotic species (e.g. Schinus molle, Prosopis laevigata, Eucalyptus globulus). We found that knowledge and valuation of plants increased with age but that they were lower for migrants; sex, by contrast, played a minor role. The age effects possibly result from decreasing ecological apparency of valuable native species, and their substitution by exotic marketable trees, loss of traditional plant uses or the use of other materials (e.g. plastic) instead of wood. Decreasing dedication to traditional farming may have led to successive abandonment of traditional tool uses, and the overall transformation of woody plant use is possibly related to diminishing medicinal knowledge. Conclusions Age and migration affect how people value woody species and what they know about their uses. For this reason, we recommend paying particular attention to the potential of native species, which could open promising perspectives especially for the young migrating peasant generation and draw their interest in

    Behavior problems of 703 children seen in a clinical setting were examined for interactions between and effects of family type (i.e., parental marital status) and age and sex of child. Significant differences were found based on family type, with children of separated, divorced, and remarried parents having more problems. Expected interactions between marital status and age and sex of child were not obtained, although results support prior research with regard to the effects of age and sex.

    Tanzania has a generalised AIDS epidemic but the estimated adult HIV prevalence of 6% is much lower than in many countries in Southern Africa. HIV infection rates are reportedly higher in urban areas, among women and among those with more education. Stigma has been found to be more common in poorer, less-educated people, and those in rural areas. We examined associations between poverty and other variables and a stigmatising attitude (belief that HIV/AIDS is punishment for sinning). The variables we examined in a multivariate model included: food sufficiency (as an indicator of poverty), age, sex, marital status, education, experience of intimate partner violence, condom-related choice disability, discussion about HIV/AIDS, sources of information about HIV/AIDS and urban or rural residence. Of the 1,130 men and 1,803 women interviewed, more than half (58%) did not disagree that "HIV/AIDS is punishment for sinning". Taking other variables into account, people from the poorest households (without enough food in the last week) were more likely to believe HIV/AIDS is punishment for sinning (Odds Ratio [OR] 1.29, 95% confidence intervals [CI] 1.06-1.59). Others factors independently associated with this stigmatising attitude were: having less than primary education (OR 1.29, 95% CI 1.03-1.62); having experienced intimate partner violence in the last year (OR 1.40, 95% CI 1.12-1.75); being choice disabled for condom use (OR 1.36, 95% CI 1.08-1.71); and living in rural areas (OR 1.76, 95% CI 1.06-2.90). The level of HIV and AIDS stigma in Tanzania is high with independent associations with several disadvantages: poverty, less education and living in rural areas. Other vulnerable groups, such as survivors of intimate partner violence, are also more likely to have a stigmatising attitude. HIV prevention programmes should take account of stigma, especially among the disadvantaged, and take care not to increase it.

    Background: Assessment and appraisal of new medical technologies require a balance between the interests of different stakeholders. Final decision should take into account the societal value of new therapies. Objective: This perspective paper discusses the socio-economic burden of disease as a specific reimbursement decision-making criterion and calls for the inclusion of it as a counterbalance to the cost-effectiveness and budget impact criteria. Results/Conclusions: Socio-economic burden is a decision-making criterion, accounting for diseases, for which the assessed medical technology is indicated. This indicator is usually researched through cost-of-illness studies that systematically quantify the socio-economic burden of diseases on the individual and on the society. This is a very important consideration as it illustrates direct budgetary consequences of diseases in the health system and indirect costs associated with patient or carer productivity losses. By measuring and comparing the socio-economic burden of different diseases to society, health authorities and payers could benefit in optimizing priority setting and resource allocation. New medical technologies, especially innovative therapies, present an excellent case study for the inclusion of socio-economic burden in reimbursement decision-making. Assessment and appraisal have been greatly concentrated so far on cost-effectiveness and budget impact, marginalizing all other considerations. In this context, data on disease burden and inclusion of explicit criterion of socio-economic burden in reimbursement decision-making may be highly beneficial. Realizing the magnitude of the lost socio-economic contribution resulting from diseases in question could be a reasonable way for policy makers to accept a higher valuation of innovative therapies.

    Patellar height is one of the important parameter in patellar stability. Growth spurt or excessive physical strain can lead to high-riding patella or patella alta. But this is not yet proved. This study was mainly targeted at eliciting the influence of age on Insall-Salvati index, one of the important index to measure patellar height. As the present study is meant for measuring the patellar height separately in male and female, it is also to find out the effect of gender on patellar height if any. The study was been conducted in North Bengal Medical College and Hospital among 93 subjects covering both adult and adolescent age groups. Patellar height of respective subjects was measured radiologically using Insall-Salvati Index; results were extrapolated for statistical analysis. It revealed that value of Insall-Salvati index was higher in adult compared to adolescent group but the difference was not statistically significant. Statistical tests shows no significant difference in Insall-Salvati index according to sex. While screening the athletes patella alta must be kept in mind as this can be associated with patellofemoral pain syndrome, chondromalacia patellae, knees with apophysitis of tibial tubercle (Osgood-Schiatter disease). Not only that, significant cause of recurrent patellar dislocation can be associated with patella alta

    We determined the best plumage and morphometric variables for ageing and sexing the Maui Parrotbill (Pseudonestor xanthophrys), an endangered Hawaiian honeycreeper found only on east Maui, Hawaii, by examining and measuring 30 museum specimens and 71 live birds captured in mist nets. Juvenal plumage was identified by the presence of pale-tipped wing bars on the middle and greater coverts, grayish olive dorsal plumage, and dingy white underparts and superciliaries. Birds undergoing first prebasic molt retained the juvenal remiges, rectrices, and wing coverts. Birds in first basic plumage possessed juvenal wing bars and a dull juvenal-like plumage. Subsequent molts were complete, and adults lacked wing bars. Adult males had bright yellow plumage on the cheeks, throat, and superciliaries, as did 27% of adult females. All other adult females had less yellow in the underparts. The dorsal plumage of adult females was more variable than adult males and was either yellow-olive like the males or grayish olive. Adult males had longer wing, bill, tail, and tarsometatarsus and greater mass than adult females. Virtually all males and females could be distinguished by wing length. Morphometrics of immature birds were significantly smaller than for adult males. Only immature male wing chord was significantly larger than that of adult females. Although it was difficult to distinguish between immatures and some adult females based on plumage coloration or measurements, a cut-off point of 70.4 mm for wing chord separated 91% of females from 93% of males, regardless of age.

    2015-01-01

    Background Obstructive sleep apnea syndrome (OSAS) is a major public health problem which affects between 5 to 10% of the general population. OSAS is known to be associated with high rates of morbidity and mortality mainly due to cardiovascular diseases and traffic accidents. The burden of illness is high for the individual and society. There are 2 treatment options for OSAS, Continuous Positive Airway Pressure (CPAP) and Mandibular Advancement Device therapy (MAD). CPAP is known to be an effective but very constraining treatment. Patients are usually poorly adherent. MAD is a more recent treatment easier to use and consequently better tolerated, but MAD can only be prescribed to patients with satisfactory oral hygiene. Oral health constitutes a real issue particularly among underprivileged groups in France. Through this link, the question of whether low socio-economic status constitutes a barrier to access to care for patients with OSAS is raised. Methods and Principal Findings In a multicenter prospective cohort of 2822 consecutive OSAS patients in whom MAD has been proposed as an alternative to CPAP between May 15, 2007 and December 1st, 2014, we identified the factors that lead to a patient diagnosed with OSAS to be treated by MAD instead of CPAP. A logistic regression was performed using a stepwise forward procedure. The main outcome of the study was that treatment by MAD was significantly associated with both educational attainment, as determined by the age at which the patient left full-time education, ≥18 years compared with <18 (adjusted odds ratio (aOR): 1.64, 95% CI 1.23 to 2.20), and the patient's occupational category. Executives and higher intellectual professions, intermediate professions, technicians, foremen and employees were significantly more likely to be treated by MAD than workers (aOR: 2.21, 95% CI 1.88 to 2.58; aOR: 1.74, 95% CI 1.15 to 2.63; aOR: 1.96, 95% CI 1.11 to 3.47, respectively). Conclusions Overall, these results suggest that low

    The aim of the present study was to identify geographical areas and time periods of potential clusters of dengue cases based on ecological, socio-economic and demographic factors in northern Sri Lanka from January 2010 to December 2013. Remote sensing (RS) was used to develop an index comprising rainfall, humidity and temperature data. Remote sensing data gathered by the AVNIR-2 instrument onboard the ALOS satellite were used to detect urbanisation, and a digital land cover map was used to extract land cover information. Other data on relevant factors and dengue outbreaks were collected through institutions and extant databases. The analysed RS data and databases were integrated into a geographical information system (GIS) enabling space-time clustering analysis. Our results indicate that increases in the number of combinations of ecological, socio-economic and demographic factors that are present or above the average contribute to significantly high rates of space-time dengue clusters. The spatio-temporal association that consolidates the two kinds of associations into one can ensure a more stable model for forecasting. An integrated spatiotemporal prediction model at a smaller level using ecological, socioeconomic and demographic factors could lead to substantial improvements in dengue control and prevention by allocating the right resources to the appropriate places at the right time.

    Developed decades ago for spatial choice problems related to zoning in the urban planning field, multicriteria analysis (MCA) has more recently been applied to environmental conflicts and presented in several documented cases for the creation of protected area management plans. Its application is considered here for the development of zoning as part of a proposed marine protected area management plan. The case study incorporates specially-explicit conservation features while considering stakeholder preferences, expert opinion and characteristics of data quality. It involves the weighting of criteria using a modified analytical hierarchy process. Experts ranked physical attributes which include socio-economically valued physical features. The parameters used for the ranking of (physical) attributes important for socio-economic reasons are derived from the field of ecosystem services assessment. Inclusion of these feature values results in protection that emphasizes those areas closest to shore, most likely because of accessibility and familiarity parameters and because of data biases. Therefore, other spatial conservation prioritization methods should be considered to supplement the MCA and efforts should be made to improve data about ecosystem service values farther from shore. Otherwise, the MCA method allows incorporation of expert and stakeholder preferences and ecosystem services values while maintaining the advantages of simplicity and clarity. PMID:27183224

    Bacillary dysentery (BD) remains a big public health problem in China. Effective spatio-temporal monitoring of BD incidence is important for successful implementation of control and prevention measures. This study aimed to examine the spatio-temporal pattern of BD and analyze socio-economic factors that may affect BD incidence in Sichuan province, China. Firstly, we used space-time scan statistic to detect the high risk spatio-temporal clusters in each year. Then, bivariate spatial correlation and Bayesian spatio-temporal model were utilized to examine the associations between the socio-economic factors and BD incidence. Spatio-temporal clusters of BD were mainly located in the northern-southern belt of the midwest area of Sichuan province. The proportion of primary industry, the proportion of rural population and the rates of BD incidence show statistically significant positive correlation. The proportion of secondary industry, proportion of tertiary Industry, number of beds in hospitals per thousand persons, medical and technical personnel per thousand persons, per capital GDP and the rate of BD incidence show statistically significant negative correlation. The best fitting spatio-temporal model showed that medical and technical personnel per thousand persons and per capital GDP were significantly negative related to the risk of BD.

    This study aims to examine the spatio-temporal dynamics of Rocky Mountain spotted fever (RMSF) prevalence in four contiguous states of Midwestern United States, and to determine the impact of environmental and socio-economic factors associated with this disease. Bayesian hierarchical models were used to quantify space and time only trends and spatio-temporal interaction effect in the case reports submitted to the state health departments in the region. Various socio-economic, environmental and climatic covariates screened a priori in a bivariate procedure were added to a main-effects Bayesian model in progressive steps to evaluate important drivers of RMSF space-time patterns in the region. Our results show a steady increase in RMSF incidence over the study period to newer geographic areas, and the posterior probabilities of county-specific trends indicate clustering of high risk counties in the central and southern parts of the study region. At the spatial scale of a county, the prevalence levels of RMSF is influenced by poverty status, average relative humidity, and average land surface temperature (>35°C) in the region, and the relevance of these factors in the context of climate-change impacts on tick-borne diseases are discussed.

    A mountain system bound to have a different path of development owing to its fragile ecological and geological setup. Any drastic and abrupt changes in this system can have repercussion beyond mitigation in form of natural disasters. The present study furnish socio-economic vulnerability mapping of the Bhagirathi basin through computation of the Socio vulnerability Index (SoVI). SVI correlates vulnerability to natural disasters to socio - economic development and illustrates how developmental parameters alter equation of potential effect and recovery in event of a natural catastrophe in the study region. An analytical framework has been imparted to understand possible triggering factors of natural disasters. Built up area expansion; land use land cover change (LULCC) - deforestation, conversion of forested land into agricultural land and residential settlements, and dam project area; road network development; urbanization; population growth & migration and pilgrimage activities are major drivers which put burden on limited carrying capacity of the natural resources. A guideline for policy making has been presented for an integrated and wholesome development incorporating regional developmental aspiration of the people and ingredients of sustainable development.

    The island Tenerife is characterized by an increasing tourism, which causes an enormous change of the socio-economic situation and a rural exodus. This development leads - beside for example sociocultural issues - to fallow land, decreasing settlements, land wasting etc., as well as to an economic and ecological problem. This causes to a growing interest in geoecological aspects and to an increasing demand for an adequate monitoring database. In order to study the change of land use and land cover, the technology of remote sensing (LANDSAT 3 MSS and 7 ETM+, orthophotos) and geographical information systems were used to analyze the spatial pattern and its spatial temporal changes of land use from end of the 70s to the present in different scales. Because of the heterogeneous landscape and the unsatisfactory experience with pixel-based classification of the same area, object-oriented image analysis techniques have been applied to classify the remote sensed data. A post-classification application was implemented to detect spatial and categorical land use and land cover changes, which have been clipped with the socio-economic data within GIS to derive the driving forces of the changes and their variability in time and space.

    Socio-economic status during childhood has been shown to be a strong predictor of adult health outcome. Therefore, we examined associations of parental educational level, household income and migrant background with physical fitness, spinal flexibility, spinal posture as well as retinal vessel diameters in children of an urban Swiss region. A total of 358 first graders of the Swiss canton Basel-Stadt (age: 7.3, SD: 0.4) were examined. Physical fitness (20 m shuttle run test, 20 m sprint, jumping sidewards and balancing backwards), spinal flexibility and spinal posture (MediMouse®, Idiag, Fehraltdorf, Switzerland) and retinal microcirculation (Static Retinal Vessel Analyzer, Imedos Systems UG, Jena, Germany) were assessed. Parental education, household income, migrant background and activity behaviour were evaluated with a questionnaire. Parental education was associated with child aerobic fitness (P = 0.03) and screen time (P < 0.001). Household income was associated with jumping sidewards (P = 0.009), balancing backwards (P = 0.03) and sports club participation (P = 0.02). Migrant background was associated with BMI (P = 0.001), body fat (P = 0.03), aerobic fitness (P = 0.007), time spent playing outdoors (P < 0.001) and screen time (P < 0.001). For spinal flexibility and retinal vessel diameter, no associations were found (0.06 < P < 0.8). Low parental education, low household income and a migrant background are associated with poor physical fitness, higher BMI and body fat percentage and low-activity behaviour.

    Previous neuroimaging studies indicate that lower socio-economic status (SES) is associated with reduced effects of selective attention on auditory processing. Here, we investigated whether lower SES is also associated with differences in a stimulus-driven aspect of auditory processing: the neural refractory period, or reduced amplitude response at faster rates of stimulus presentation. Thirty-two children aged 3 to 8 years participated, and were divided into two SES groups based on maternal education. Event-related brain potentials were recorded to probe stimuli presented at interstimulus intervals (ISIs) of 200, 500, or 1000 ms. These probes were superimposed on story narratives when attended and ignored, permitting a simultaneous experimental manipulation of selective attention. Results indicated that group differences in refractory periods differed as a function of attention condition. Children from higher SES backgrounds showed full neural recovery by 500 ms for attended stimuli, but required at least 1000 ms for unattended stimuli. In contrast, children from lower SES backgrounds showed similar refractory effects to attended and unattended stimuli, with full neural recovery by 500 ms. Thus, in higher SES children only, one functional consequence of selective attention is attenuation of the response to unattended stimuli, particularly at rapid ISIs, altering basic properties of the auditory refractory period. Together, these data indicate that differences in selective attention impact basic aspects of auditory processing in children from lower SES backgrounds.

    The impact of socio- economic and demographic status (SEDS) factors on the stage of cervical cancer rat diagnosis, symptom duration and delay-time from diagnosis to registration was determined by analysing data for the year 2006 from the Regional Cancer Centre (RCC), Trivandrum, Kerala, India. Patients (n=349) were included if they were from the states of Kerala or Tamil Nadu. SEDS factors included age, residing district, religion, marital status, income, education and occupation. Associations between SEDS factors by stage at diagnosis and symptom duration were tested using chi-square statistics with odds ratios (OR) estimated through logistic regression modeling. Elevated risks for late stage reporting among cervical cancer patients were observed for women who were widowed/divorced (OR=2.08; 95%CI: 1.24-3.50) and had a lower education (OR=2.62; 95%CI:1.29-5.31 for women with primary school education only). Patients who had symptoms of bleeding/bleeding with other symptoms (77%) were more likely to seek treatment within one month, compared to patients with other symptoms only (23%) (p=0.016). This analysis helped to identify populations at increased risk of diagnosis at later stages of cancer with the ultimate intent of providing health education and detecting cancer at earlier stages.

    Object control skills provide children the tools to be physically active-a major societal priority. At the fundamental movement level, object control skills form the foundation of further sports skill development. The purpose of this study was to examine children's (ages 5 to 14 years, Grades K-8) development of four key object control skills: catching, throwing, kicking, and striking. 186 children were tested on selected items from the Object Control Subtest of the Test of Gross Motor Development-2, using a cross-sectional and correlational design. As anticipated, significant differences were found for age on all four skills. These improvements were characterized by early, rapid gains at ages 9 to 10, beyond which development occurred at a slower rate for catching, throwing, and kicking; striking development continued at a steady rate to age 14 years. Contrary to previous findings, no overall sex differences were found for catching or kicking. Overall sex differences favoring boys were observed for throwing and striking. Implications for evolutionary contributions to throwing and striking were discussed.

    A cross-sectional population-based survey was undertaken to evaluate the relationship between nutritional status and parasitic infections of schoolchildren and demographic, socio-economic factors in Sanliurfa province, southern Turkey. Nine hundred and eight schoolchildren took part in the survey: 57.2% boys and 42.7% girls. The children's mean z scores were as follows: height for age-0.8 (+/-1.0) and weight for age-1.0 (+/-0.9). The mean haemoglobin concentration was 123 g/l (+/-2.1) and the prevalence of parasitic infections was 55.1%. In total, 50.2% of children were hungry when they arrived at school and 13.4% worked after school. Over 70% (70.4%) of mothers and 18.1% of fathers were illiterate, 16.1% of fathers were unemployed and 46.3% of fathers were engaged in low-income labour. The mean number of children in each family was 5.4 (+/-2.5), and the mean number of children from each family who attended school was 2.1 (+/-1.1). The school-attendance ratio was 0.4 (+/-1.0). Data indicated that older children had significantly lower mean z scores of height (P < 0.0001) and weight for age (P < 0.0001) than younger children, and boys had significantly lower mean z scores of height for age than girls (P < 0.0001). Children living in shantytown areas had significantly lower mean z scores of height for age (P < 0.0001) and weight for age (P < 0.0001), lower mean haemoglobin concentrations (P : 0.003)and a worse parasitic infection status (P < 0.0001) than those living in apartment areas. Children who were hungry when they arrived at school had significantly lower mean haemoglobin concentrations than those who had eaten (P : 0.04). Multiple regression analyses indicated that mean z scores of height for age were significantly related to maternal (multiple R = 0.183; P < 0.0001) and paternal illiteracy (multiple R = 0.216; P : 0.004). Mean z scores of weight for age were significantly related to maternal illiteracy (multiple R = 0.154; P < 0.0001), as was parasitic

    Introduction Overweight and obesity are a public health problem in India not only in adults but also in children. The authors sought to estimate the prevalence of overweight and obesity in school-going children of 6–17 years of age and examine its demographic and dietary correlates in context of their urban-rural status and socio-economic status. Methods In this cross-sectional survey height and weight were measured in 1266 school children in government and private schools of urban and rural areas. Dietary assessment was done using single day 24-hour dietary recall method. The data were analyzed using SPSS (IBM SPSS Statistics Version 19) and WHO AnthroPlus Software. Factorial ANOVA was used for testing interaction within and between subgroups for continuous variables and Chi-square test was used for categorical variables. Results It was found that the overall prevalence of overweight was 15.6% of which 5.4% were obese, with maximum prevalence in boys attending urban private schools. The mean caloric intake in the study population with 24-hour dietary recall method was 1558.2 kilocalories (SD: 428 kilocalories). Conclusion Overweight and obesity is a significant problem in school-going children. Higher socio-economic status continues to remain an important driver of this epidemic in the younger generation and affects demographic and dietary determinants of this problem. PMID:27227780

    The associate learning subtest from the Wechsler Memory Scale; Benton's Visual Retention test and a Controlled Word Association Task (FAS) were administered to a random sample of normal, healthy individuals whose age ranged from 20 to 79 years, recruited within the Italian peninsula. The neuropsychological examination took place on a mobile unit and the tests were given by the same team of neuropsychologists to reduce variability among examiners. The Research Project was known as Progetto Memoria. Corrections to the scores of these tests were calculated for age, sex, and education. These corrected values will allow clinicians to screen for memory impairment with greater precision among normally aging individuals, thus improving differential diagnosis between physiologic and pathologic deterioration of cognitive functions.

  12. Assessment of environmental change and its socio-economic impacts in the mangrove ecological zone of the Niger Delta, Nigeria

    James, Godstime Kadiri

    The Niger Delta, located in the central part of Southern Nigeria, is endowed with immense Mangrove resources, estimated to be the fourth largest in the world. The term Mangrove refers to salt tolerant species of trees or shrubs that grow on shores and in estuaries located in the coastal tropics and sub-tropical regions of the world. They support highly productive marine food chains. However, Mangrove ecosystems are in serious decline around the world due to the rapid increase in maritime commerce and exploration of mineral resources in the last few decades. These pressures often have immediate consequences on sensitive coastal environments and can potentially impact future human use of coastal space and resources. This dynamic process presents unique opportunities for research to explore the nature and consequences of these pressures. This dissertation focused on the Mangrove ecological zone of the Niger Delta, where resource exploitation and indigenous use of the environment are in direct conflict with important socio-economic implications. Environmental accounting metrics derived from the Driver-Pressure-State-Impact-Response (DPSIR) framework were used to assess changes in the spatial extent of the Niger Delta Mangrove ecosystem and the socio-economic impacts of the observed changes. Landsat remotely sensed satellite data from the mid-1980s through 2003 was used to assess change in the spatial extent of the Mangrove vegetation in the region. A total of 21,340 hectares of Mangrove forest was determined to be lost over the study period. Field research in the region confirmed that this loss was primarily driven by urbanization and activities of the multinational oil and gas corporations operating in the region. To estimate the socio-economic impacts of the Mangrove loss in the region, neoclassical economic valuation and participatory social valuation approaches were adopted. Results from the economic valuation revealed that the net present value of future income

    There are considerable data addressing sex-related differences in cardiovascular system aging and disease risk/progression. Sex differences in cardiovascular aging are evident during resting conditions, exercise, and other acute physiological challenges (e.g., orthostasis). In conjunction with these sex-related differences-or perhaps even as an underlying cause-the impact of cardiorespiratory fitness and/or physical activity on the aging cardiovascular system also appears to be sex-specific. Potential mechanisms contributing to sex-related differences in cardiovascular aging and adaptability include changes in sex hormones with age as well as sex differences in baseline fitness and the dose of activity needed to elicit cardiovascular adaptations. The purpose of the present paper is thus to review the primary research regarding sex-specific plasticity of the cardiovascular system to fitness and physical activity in older adults. Specifically, the paper will (1) briefly review known sex differences in cardiovascular aging, (2) detail emerging evidence regarding observed cardiovascular outcomes in investigations of exercise and physical activity in older men versus women, (3) explore mechanisms underlying the differing adaptations to exercise and habitual activity in men versus women, and (4) discuss implications of these findings with respect to chronic disease risk and exercise prescription.

    Background In Kasensero fishing community, home of the first recorded case of HIV in Uganda, HIV transmission is still very high with an incidence of 4.3 and 3.1 per 100 person-years in women and men, respectively, and an HIV prevalence of 44%, reaching up to 74% among female sex workers. We explored drivers for the high HIV transmission at Kasensero from the perspective of fishermen and other community members to inform future policy and preventive interventions. Methods 20 in-depth interviews including both HIV positive and HIV negative respondents, and 12 focus-group discussions involving a total of 92 respondents from the Kasensero fishing community were conducted during April-September 2014. Content analysis was performed to identify recurrent themes. Results The socio-economic risk factors for high HIV transmission in Kasensero fishing community cited were multiple and cross-cutting and categorized into the following themes: power of money, risk denial, environmental triggers and a predisposing lifestyle and alcoholism and drug abuse. Others were: peer pressure, poor housing and the search for financial support for both the men and women which made them vulnerable to HIV exposure and or risk behavior. Conclusions There is a need for context specific combination prevention interventions in Kasensero that includes the fisher folk and other influential community leaders. Such groups could be empowered with the knowledge and social mobilization skills to fight the negative and risky behaviors, perceptions, beliefs, misconceptions and submission attitudes to fate that exposes the community to high HIV transmission. There is also need for government/partners to ensure effective policy implementation, life jackets for all fishermen, improve the poor housing at the community so as to reduce overcrowding and other housing related predispositions to high HIV rates at the community.

    Blood pressure and other risk factors of cardiovascular diseases were studied in two rural communities of 631 adults (greater than or equal to 18 years old) with different socio-economic statuses, populations A and B. Population A (n = 381) lived in a tourist village on an island, and population B (n = 250) in a remote mountain village. The socio-economic status of population A had improved considerably over the last decade but the physical environment, habits, culture and way of life had been disrupted. Blood pressure, prevalence of hypertension and other risk factors were higher than in population B where socio-economic status was lower but where there had been no disruption of the environment, traditional habits, culture or way of life. These findings might be due to the lack of preventive medicine services in the community.

    Sex-typed behavior in childhood is significantly related to sexual orientation in adulthood. In addition, same-sex attractions in early adolescence are more non-exclusive than in adulthood and can differ from later same-sex orientations. However, little research has focused on romantic attractions as they emerge during early adolescence. Drawing a sample from the Avon Longitudinal Study of Parents and Children (197 girls, 204 boys), the current study examined whether same-sex romantic attractions at age 13 years were exclusive, and whether they were predicted by sex-typed behavior at age 3.5 years. No young adolescents in this sample reported exclusive same-sex attractions, and increased same-sex attractions were not significantly related to reduced other-sex sexualities. Childhood sex-typed behavior did not significantly predict early same-sex attractions, suggesting that early same-sex attractions differ from later same-sex orientations. The current study highlights the importance of studying the development of sexuality beginning prior to adulthood.

    Research on micro-level assessment of the changes of socio-economic status following health interventions is very scarce. The use of household asset data to determine wealth indices is a common procedure for estimating socio-economic position in resource poor settings. In such settings information about income is usually lacking, and the collection of individual consumption or expenditure data would require in-depth interviews, posing a considerable risk of bias. In this study, we determined the socio-economic status of 213 households in a community population in an island in the north-western Tanzania before and 3 year after implementation of a participatory hygiene and sanitation transformation (PHAST) intervention to control schistosomiasis and intestinal worm infections. We constructed a household 'wealth index' based housing construction features (e.g., type of roof, walls, and floor) and durable assets ownership (e.g., bicycle, radio, etc.). We employed principal components analysis and classified households into wealth quintiles. The study revealed that asset variables with positive factor scores were associated with higher socio-economic status, whereas asset variables with negative factor scores were associated with lower socio-economic status. Overall, households which were rated as the poorest and very poor were on the decrease, whereas those rated as poor, less poor, and the least poor were on the increase after PHAST intervention. This decrease/increase was significant. The median shifted from -0.4376677 to 0.5001073, and the mean from -0.2605787 (SD; 2.005688) to 0.2605787 (SD; 1.831199). The difference in socio-economic status of the people between the 2 phases was highly statistically significant (P<0.001). We argue that finding of this study should be treated with caution as there were other interventions to control schistosomiasis and intestinal worm infections which were running concurrently on Kome Island apart from PHAST intervention.

    For its fifth assessment report, the Intergovernmental Panel on Climate Change divided future scenario projections (2005-2100) into two groups: Socio-Economic Pathways (SSPs) and Representative Concentration Pathways (RCPs). Each SSP has country-level urban and rural population projections, while the RCPs are based on radiative forcing caused by greenhouse gases, aerosols and associated land-use change. In order for these projections to be applicable in earth system models, SSP and RCP population projections must be at the same spatial scale. Thus, a gridded population dataset that takes into account both RCP-based urban fractions and SSP-based population projection is needed. To support this need, an annual (2000-2100) high resolution (approximately 1km at the equator) gridded population dataset conforming to both RCPs (urban land use) and SSPs (population) country level scenario data were created.

    Human newborns are vulnerable to infectious diseases that account for majority of the morbidity and mortality, particularly in first year of life. Vaccines have become the most effective public health intervention strategy to curtail the prevalence of these infectious diseases. Although vaccines against a number of diseases exist, there are no vaccines against many other diseases that commonly affect children. The adequate assessment of immune responses to vaccines is an important step in the development of vaccines. However, a number of biological and "non-medical" socio-economic and ethical factors could influence either the administration and/or evaluation of vaccines in infants. Recognition and understanding of these determinants are crucial in planning interventions and for logical interpretations of results.

    Arguably one of the most important effects of climate change is the potential impact on human health. While this is likely to take many forms, the implications for future transmission of vector-borne diseases (VBDs), given their ongoing contribution to global disease burden, are both extremely important and highly uncertain. In part, this is owing not only to data limitations and methodological challenges when integrating climate-driven VBD models and climate change projections, but also, perhaps most crucially, to the multitude of epidemiological, ecological and socio-economic factors that drive VBD transmission, and this complexity has generated considerable debate over the past 10-15 years. In this review, we seek to elucidate current knowledge around this topic, identify key themes and uncertainties, evaluate ongoing challenges and open research questions and, crucially, offer some solutions for the field. Although many of these challenges are ubiquitous across multiple VBDs, more specific issues also arise in different vector-pathogen systems.

Finally the concept of Social Health shall be expounded as a category of analysis which may permit the understanding of the methodological inexactitude which involves creating the characteristics and possibilities of a health service outside the socio-economic model.

    The relationships between ethnicity, socio-economic status (SES) and health-related quality of life (HRQoL) have not been well characterised in most Asian populations. We therefore studied the influence of ethnicity and SES on HRQoL in a multi-ethnic urban Asian population, adjusting for the influence of other known determinants of HRQoL. In a disproportionately stratified, cross-sectional, population-based survey, Chinese, Malay and Indian subjects in Singapore completed the Short Form 36 Health Survey (SF-36) HRQoL measure and were assessed to determine demographic, socio-economic, psychosocial and other characteristics. Multiple linear regression models were used to study the influence of ethnicity and SES on SF-36 scores while adjusting for the influence of other determinants of HRQoL. The survey participation rate was 92.8%. Ethnic differences in HRQoL were present for all 8 SF-36 scales (p<0.001 for all scales except General Health) among the 4122 Chinese, Malays and Indians surveyed. These ethnic groups also differed in several known determinants of HRQoL (e.g., Chinese had more years of education and Indians had more chronic medical conditions). After adjusting for the influence of these factors, ethnicity and SES independently influenced HRQoL, with mean differences in SF-36 scores due to ethnicity ranging from 1.4 to 13.1 points. Educational level and housing type (markers of SES) were also associated with SF-36 scores (0.5-0.6 point increase per year of education and 3.5-4.0 point increase with better housing type, respectively). Better HRQoL was also associated with better family support, and poorer HRQoL with acute and chronic medical conditions and sick days. The study concludes that ethnicity and SES are associated with clinically important differences in HRQoL in a multi-ethnic, urban Asian population.

    The development of the Water Framework Directive aimed to establish an integrated framework of water management at European level. This framework revolves around inland surface waters, transitional waters, coastal waters and ground waters. In the process of achieving the environment and ecological objectives set from the Directive, the role of economics is put in the core of the water management. An important feature of the Directive is the recovery of total economic cost of water services by all users. The total cost of water services can be disaggregated into environmental, financial and resource costs. Another important aspect of the directive is the identification of major drivers and pressures in each River Basin District. We describe a methodology that is aiming to achieve sustainable and environmental and socioeconomic management of freshwater ecosystem services. The Ecosystem Services Approach is in the core of the suggested methodology for the implementation of a more sustainable and efficient water management. This approach consists of the following three steps: (i) socio-economic characterization of the River Basin area, (ii) assessment of the current recovery of water use cost, and (iii) identification and suggestion of appropriate programs of measures for sustainable water management over space and time. This methodology is consistent with a) the economic principles adopted explicitly by the Water Framework Directive (WFD), b) the three-step WFD implementation approach adopted in the WATECO document, c) the Ecosystem Services Approach to valuing freshwater goods and services to humans. Furthermore, we analyze how the effects of multiple stressors and socio-economic development can be quantified in the context of freshwater resources management. We also attempt to estimate the value of four ecosystem services using the benefit transfer approach for the Anglian River Basin, which showed the significance of such services.

    Azerbaijan is a country with one of the highest child mortality rates in the regions of Eastern Europe and the former Soviet Union. Drawing on the nationally representative Demographic and Health Survey, this study examines the utilization of antenatal care in Azerbaijan to identify the socio-economic determinants of the usage, and its frequency, timing and quality. Consequently, binomial logit, two ordered logit and negative binomial regression models are specified to estimate the effect of various socio-economic characteristics on the likelihood of utilization. Place of living is an important determinant of antenatal healthcare utilization in Azerbaijan. It is important in determining the likelihood of utilization, its timing and quality of care received, whereas it is not significant in the model predicting the frequency of antenatal utilization. Women's education is also significant in three models out of four. Education is important in explaining the frequency and timing of utilization as well as the quality of services received, but it is not significant in predicting the likelihood of utilization. Wealth gradient is another important determinant of antenatal care utilization in Azerbaijan inasmuch as it is significant in explaining the likelihood of prenatal care utilization and its frequency. In addition, two variables, birth order and desirability of the last child or current pregnancy, are significant only in explaining the likelihood of utilization. Therefore, we confirm the findings of previous studies, which reported that the utilization of prenatal health care is a multistage process in which decisions are sequential. Although the same set of factors may affect decision-making at all stages, the effect of these factors is different at different stages. Implications for reforms in the healthcare sector to improve antenatal care utilization in Azerbaijan are provided and discussed.

    Climate change is predicted to negatively impact many agricultural communities across the globe, particularly smallholder farmers who often do not have access to appropriate technologies to reduce their vulnerability. To better predict which farmers will be most impacted by future climate change at a regional scale, we use remote sensing and agricultural census data to examine how cropping intensity and crop type have shifted based on rainfall variability across Gujarat, India from 1990 to 2010. Using household-level interviews, we then identify the socio-economic, biophysical, perceptional, and psychological factors associated with smallholder farmers who are the most impacted and the least able to adapt to contemporaneous rainfall variability. We interviewed 750 farmers in 2011 and 2012 that span a rainfall, irrigation, socio-economic, and caste gradient across central Gujarat. Our results show that farmers shift cropping practices in several ways based on monsoon onset, which farmers state is the main observable rainfall signal influencing cropping decisions during the monsoon season. When monsoon onset is delayed, farmers opt to plant more drought-tolerant crops, push back the date of sowing, and increase the number of irrigations used. Comparing self-reported income and yields, we find that switching crops does not improve agricultural income, shifting planting date does not influence crop yield, yet increasing the number of irrigations significantly increases yield. Future work will identify which social (e.g. social networks), psychological (e.g. risk preference), and knowledge (e.g. information sources) factors are associated with farmers who are best able to adapt to rainfall variability.

    One of the problems in an ecosystem approach to fisheries management is the lack of economic analyses which clearly define the performance of different fishing fleets within the system. We describe a comparative multi-fleet analysis of socio-economic indicators applicable for inclusion into ecosystem modeling and management. Based on a survey of different industrial fishing fleets in São Paulo, Southeastern Brazil, an inter-fleet comparison of economic attributes such as investment, fixed costs, effort, labour, sailing-related costs and profits, as well as a set of performance indicators, was conducted. Costs varied between fleets with fuel being the largest component on average, representing almost 37% of total costs. Similarities between fleets were driven by fuel costs, gross incomes and profits. In general, the best economic performance was associated with indicators of profitability and economic efficiency. Bottom-longliners and both surface and bottom-gillnet fleets showed the best economic performance per fishing trip due to their low percentage of variable costs. Purse-seiners and pink-shrimp trawlers had the lowest average rate of return and economic efficiency because of their high variable costs and relatively low catch values, and were considered economically net losers. However, in terms of jobs generated, purse-seiners had the greatest value creating about 49% of total jobs by all fleets. The sea-bob-shrimp fleet had the lowest crew size per vessel but generated the second highest total number of direct jobs (23%), with high economic viability as a whole. The inter-fleet cost and socio-economic performance analysis revealed that additional attention should be given to the poor profitability and overcapacity of fleets, fishing impacts, and open-access related issues, while social indicators may also be considered. This study provides information useful for evaluating different fisheries management scenarios and fleet size optimization in the South

    Background/Objectives Understanding the factors underlying the spatio-temporal distribution of infectious diseases provides useful information regarding their prevention and control. Dengue fever spatio-temporal patterns result from complex interactions between the virus, the host, and the vector. These interactions can be influenced by environmental conditions. Our objectives were to analyse dengue fever spatial distribution over New Caledonia during epidemic years, to identify some of the main underlying factors, and to predict the spatial evolution of dengue fever under changing climatic conditions, at the 2100 horizon. Methods We used principal component analysis and support vector machines to analyse and model the influence of climate and socio-economic variables on the mean spatial distribution of 24,272 dengue cases reported from 1995 to 2012 in thirty-three communes of New Caledonia. We then modelled and estimated the future evolution of dengue incidence rates using a regional downscaling of future climate projections. Results The spatial distribution of dengue fever cases is highly heterogeneous. The variables most associated with this observed heterogeneity are the mean temperature, the mean number of people per premise, and the mean percentage of unemployed people, a variable highly correlated with people's way of life. Rainfall does not seem to play an important role in the spatial distribution of dengue cases during epidemics. By the end of the 21st century, if temperature increases by approximately 3°C, mean incidence rates during epidemics could double. Conclusion In New Caledonia, a subtropical insular environment, both temperature and socio-economic conditions are influencing the spatial spread of dengue fever. Extension of this study to other countries worldwide should improve the knowledge about climate influence on dengue burden and about the complex interplay between different factors. This study presents a methodology that can be used as a

This paper describes an empirical study based on biographical life narrative interviews with 45 16-year olds from inner London who were considering applying to medical school, drawn mainly from the most socio-economically deprived 25% of the population. Most of them were immigrants or the children of immigrants, and all had been selected by their teachers as highly able and motivated. Students were asked to "tell the story of your life so far". Interviews were tape recorded, transcribed and analysed thematically. Five influences on the development of academic identity and medical ambition were identified: (1) the private sphere (Bourdieu's 'family habitus'), especially a family meta-narrative of immigration to secure a better future and of education as the vehicle to regaining a high social position previously held in the family of origin; (2) the school (Bourdieu's 'institutional habitus'), and especially the input of particular teachers who inspired and supported the student; (3) friends and peers, many of whom the student had chosen strategically because of shared aspirations to academic success; (4) psychological resources such as maturity, determination and resilience; and (5) past experiences (especially meeting the challenge of immigration, changing school, or dealing with illness or death in a relative), which had proved formative and strengthening to the individual's developing ego. Despite their talents and ambitions, many students had important gaps in their knowledge of the application process and lacked sophistication in the 'admissions game'. The findings are discussed in relation to contemporary educational and social theories.

    Both planning and design of integrated municipal solid waste management systems require accurate prediction of waste generation. This research predicted the quantity and distribution of biodegradable municipal waste (BMW) generation within a diverse 'landscape' of residential areas, as well as from a variety of commercial establishments (restaurants, hotels, hospitals, etc.) in the Dublin (Ireland) region. Socio-economic variables, housing types, and the sizes and main activities of commercial establishments were hypothesized as the key determinants contributing to the spatial variability of BMW generation. A geographical information system (GIS) 'model' of BMW generation was created using ArcMap, a component of ArcGIS 9. Statistical data including socio-economic status and household size were mapped on an electoral district basis. Historical research and data from scientific literature were used to assign BMW generation rates to residential and commercial establishments. These predictions were combined to give overall BMW estimates for the region, which can aid waste planning and policy decisions. This technique will also aid the design of future waste management strategies, leading to policy and practice alterations as a function of demographic changes and development. The household prediction technique gave a more accurate overall estimate of household waste generation than did the social class technique. Both techniques produced estimates that differed from the reported local authority data; however, given that local authority reported figures for the region are below the national average, with some of the waste generated from apartment complexes being reported as commercial waste, predictions arising from this research are believed to be closer to actual waste generation than a comparison to reported data would suggest. By changing the input data, this estimation tool can be adapted for use in other locations. Although focusing on waste in the Dublin region

    Developing countries often have rich natural resources but poor infrastructure to capitalize on them, which leads to significant challenges in terms of balancing poverty alleviation with conservation. The underlying premise in development strategies is to increase the socio-economic welfare of the people while simultaneously ensuring environmental sustainability, however these objectives are often in direct conflict. National progress is dependent on developing infrastructure such as effective transportation networks, however roads can be ecologically catastrophic in terms of disrupting habitat connectivity and facilitating illegal activity. How can national development and conservation be balanced? The proposed Serengeti road epitomizes the conflict between poverty alleviation on one hand, and the conservation of a critical ecosystem on the other. We use the Serengeti as an exemplar case-study in which the relative economic and social benefits of a road can be assessed against the ecological impacts. Specifically, we compare three possible transportation routes and ask which route maximizes the socio-economic returns for the people while minimizing the ecological costs. The findings suggest that one route in particular that circumnavigates the Serengeti links the greatest number of small and medium sized entrepreneurial businesses to the largest labour force in the region. Furthermore, this route connects the most children to schools, provisions the greatest access to hospitals, and opens the most fertile crop and livestock production areas, and does not compromise the ecology and tourism revenue of the Serengeti. This route would improve Tanzania’s food security and self-reliance and would facilitate future infrastructure development which would not be possible if the road were to pass through the Serengeti. This case study provides a compelling example of how a detailed spatial analysis can balance the national objectives of poverty alleviation while

    Frequent consumption of energy-dense foods has been strongly implicated in the global increase of obesity. The World Cancer Research Fund suggests a population-level energy density (ED) goal for diets of 523 kJ/100 g (125 kcal/100 g) as desirable for reducing weight gain and related co-morbidities. However, there is limited inform
