OBJECTIVES—As self rated health and mortality represent different dimensions of public health and as risk behaviours have been closely related to mortality, we wanted to examine whether (poor) self rated health on the one hand and risk behaviours on the other can be attributed to different causes. METHODS—The Taganrog household survey (1998) was conducted in the form of face to face interviews and included 1009 people and their families. To estimate health differences and differences in risk behaviours between groups, logistic regressions were performed. RESULTS—In Taganrog between 1993/94 and 1998, changes in self rated health seem to have been much more dramatic than changes in smoking and different in direction from changes in heavy alcohol consumption. Moreover, self rated "poor" health was especially common among those whose economic situation was worse in 1998 than 10 years before. However, having a poorer economy during the period 1988-1998, does not seem to have affected drinking or smoking habits significantly. CONCLUSIONS—Self rated health seems to be closely related to three indicators of economic circumstances. Risk behaviours are probably important for the poor state of public health in Russia, but may be less sensitive to the economic aspects of the transition than is self rated health.

Using the 1980 to 2002 General Social Survey, a repeated cross-sectional study that has been linked to the National Death Index through 2008, this study examines the changing relationship between self-rated health and mortality. Research has established that self-rated health has exceptional predictive validity with respect to mortality, but this validity may be deteriorating in light of the rapid medicalization of seemingly superficial conditions and increasingly high expectations for good health. Yet the current study shows the validity of self-rated health is increasing over time. Individuals are apparently better at assessing their health in 2002 than they were in 1980 and, for this reason, the relationship between self-rated health and mortality is considerably stronger across all levels of self-rated health. Several potential mechanisms for this increase are explored. More schooling and more cognitive ability increase the predictive validity of self-rated health, but neither of these influences explains the growing association between self-rated health and mortality. The association is also invariant to changing causes of death, including a decline in accidental deaths, which are, by definition, unanticipated by the individual. Using data from the final two waves of data, we find suggestive evidence that exposure to more health information is the driving force, but we also show that the source of information is very important. For example, the relationship between self-rated health and mortality is smaller among those who use the internet to find health information than among those who do not.

Several studies have found that older women report lower self-rated health than men. However, it is not clear why older women are more likely to report poor self-rated health than older men. Data for this study came from a national cross-sectional survey, Mental Health and Quality of Life of Older Malaysians (MHQoLOM). Included in the survey were…

OBJECTIVE To analyze the association between negative self-rated health and indicators of health, wellbeing and sociodemographic variables in older adults. METHODS Cross-sectional study that used data from a population-based health survey with a probability cluster sample that was carried out in Campinas, SP, Southeastern Brazil,, in 2008 and 2009. The participants were older adults (≥ 60 years) and the dependent variable was self-rated health, categorized as: excellent, very good, good, bad and very bad. The adjusted prevalence ratios were estimated by means of Poisson multiple regression. RESULTS The highest prevalences of bad/very bad self-rated health were observed in the individuals who never attended school, in those with lower level of schooling, with monthly per capita family income lower than one minimum salary. Individuals who scored five or more in the physical health indicator also had bad self-rated health, as well as those who scored five or more in the Self-Reporting Questionnaire 20 and those who did not refer feeling happiness all the time. CONCLUSIONS The independent effects of material life conditions, physical and mental health and subjective wellbeing, observed in self-rated health, suggest that older adults can benefit by health policies supported by a global and integrative view of old age.

The purpose of this study was to study the determinants of self rated health in the low-risk pregnant women of Melaka Tengah in Malaysia. A total of 387 subjects were analysed. The role of mental health, psychosocial stressors, support from husband, coping skills, socio-economic status and pregnancy characteristics in determining self- rated health were studied. Health items were taken from the Duke Health Profile. Bad obstetric history, poor mental health, stress from the family were found to be significantly associated with poor self - rated health whereas good support from the husband was related to good self - rated health.

OBJECTIVES: This study tested the hypothesis that disparities in political participation across socioeconomic status affect health. Specifically, the association of voting inequality at the state level with individual self-rated health was examined. METHODS: A multilevel study of 279,066 respondents to the Current Population Survey (CPS) was conducted. State-level inequality in voting turnout by socioeconomic status (family income and educational attainment) was derived from November CPS data for 1990, 1992, 1994, and 1996. RESULTS: Individuals living in the states with the highest voting inequality had an odds ratio of fair/poor self-rated health of 1.43 (95% confidence interval [CI] = 1.22, 1.68) compared with individuals living in the states with the lowest voting inequality. This odds ratio decreased to 1.34 (95% CI = 1.14, 1.56) when state income inequality was added and to 1.27 (95% CI = 1.10, 1.45) when state median income was included. The deleterious effect of low individual household income on self-rated health was most pronounced among states with the greatest voting and income inequality. CONCLUSIONS: Socioeconomic inequality in political participation (as measured by voter turnout) is associated with poor self-rated health, independently of both income inequality and state median household income.

We study whether migrant health in Europe is associated with the cultural distance between their host country and country of origin. To this end, we run multilevel regression models on data merging self-rated health and social background of ≥3800 migrants from the European Social Survey with an index of cultural distance based on country differences in values, norms and attitudes measured in the World Values Survey. We find that higher levels of cultural distance are associated with worse migrant health. This association is comparable in size with the negative association between health and female (compared with male) gender but less important than the association between health and education level. In addition, this association is less significant among second-generation than first-generation migrants.

Objectives Self-rated health (SRH) is a commonly used measure in surveys to assess general health status or health-related quality of life. Differences have been detected in how different ethnic groups and nationalities interpret the SRH measure and assess their health. This review summarizes the research conducted on SRH within and between ethnic groups, with a focus on indigenous groups. Study design and methods A search of published academic literature on SRH and ethnicity, including a comprehensive review of all relevant indigenous research, was conducted using PubMed and summarized. Results A wide variety of research on SRH within ethnic groups has been undertaken. SRH typically serves as an outcome measure. Minority respondents generally rated their health worse than the dominant population. Numerous culturally-specific determinants of SRH have been identified. Cross-national and cross-ethnicity comparisons of the associations of SRH have been conducted to assess the validity of SRH. While SRH is a valid measure within a variety of ethnicities, differences in how SRH is assessed by ethnicities have been detected. Research in indigenous groups remains generally under-represented in the SRH literature. Conclusions These results suggest that different ethnic groups and nationalities vary in SRH evaluations, interpretation of the SRH measure, and referents employed in rating health. To effectively assess and redress health disparities and establish culturally-relevant and effective health interventions, a greater understanding of SRH is required, particularly among indigenous groups, in which little research has been conducted.

The aim of this study was to investigate what psychosocial predictors, life-style factors and health behaviors in early adulthood are of importance for self-ratings of health after the age of 45. Like-sexed adult twins born 1926-1950 (n = 16,080) from the Swedish Twin Registry that participated in a questionnaire in 1973 and in a telephone interview conducted between 1998 and 2002 were included. Exposure data was collected in 1973 and information on self-rated health and covariates was collected at the second contact 25 years later. Logistic regression using Generalized Estimating Equations was used to evaluate the associations. Conditional logistic regression was used to control for familial and genetic effects in the sample. Pain, lack of exercise, smoking, obesity, unemployment, perceived stress and personality are associated with future poor self-rated health, after controlling for age, sex, illness, education and socio-economic status. Familial and genetic effects influence the associations between recurrent headache, exercise, obesity, and poor self-rated health. Overall, these findings provide support for long-term effects of health behavior and psychosocial risk factors on poor self-ratings of health, beyond the influence of obvious health consequences such as disorders or illnesses. Genetic and familial factors are of importance only for some of these associations.

Objective: The study examined the relationship of self-rated health and self-rated economic situation with depressed mood, and life satisfaction as mediator of this relationship among older adults in Costa Rica. Method: A longitudinal study was conducted with a subsample (N = 1,618) from the Costa Rican Longevity and Healthy Aging Study (CRELES). Self-rated health, self-rated economic situation, depressed mood, and life satisfaction were measured at baseline, and depressed mood was reassessed 18 months later. Putative mechanisms for changes in depressed mood were examined by means of conditional process analysis. Results: Self-rated health was negatively associated to depressed mood. This effect took place via life satisfaction. An interaction showed that better economic situation compensated the effect of a low self-rated health on life satisfaction. Discussion: This study suggests that subjective variables such as self-rated health, economic situation, and life satisfaction should be considered when addressing the onset of depressed mood.

Although research has explored the association between marital quality and physical health in marriage, existing research fails to consider possible bidirectional associations between changes in individuals' marital quality and self-rated health. To address this gap, this study used latent change models to assess whether adults' marital happiness and problems over a 20-year period predicted subsequent changes in self-rated health, as well as whether self-rated health over the same time period was associated with changes in marital happiness and problems. The sample included 707 continuously married adults who participated in all six waves of the Marital Instability Over the Life Course panel study. Participants averaged 35 years in age at the first wave and were continuously married to the same spouse over the 20-year period. Latent differential models in AMOS 19 showed that unidirectional coupling existed for marital happiness and self-rated health only, such that higher levels of marital happiness predicted subsequent elevations in self-rated health over time. No evidence was found for bidirectional coupling between marital problems and self-rated health. Possible explanations for these patterns of results are discussed, including important directions for future researchers.

Abstract Both clinical diagnoses and self-rated measures of mental illness are associated with a variety of outcomes, including physical well-being, health utilization, and expenditure. However, much of current literature primarily utilizes clinically diagnosed data. This cross-sectional study explores the impact of mental illness and health care expenditure using 2 self-rated measures: self-rated measured of perceived mental health status (SRMH) and Kessler Screening Scale for Psychological Distress (K6). Data from the 2011 Medical Expenditure Panel Survey Household Component, a nationally representative sample of noninstitutionalized individuals (n = 18,295), were analyzed using bivariate χ2 tests and a 2-part model (logistics regression and generalized linear model regression for the first and second stages, respectively). Although predictive of any health expenditure, SRMH alone was not highly predictive of the dollar value of that health expenditure conditional on any spending. By comparison, the K6 measure was significantly and positively associated with the probability of any health expenditure as well as the dollar value of that spending. Taken together, both the K6 and SRMH measures suggest a positive relationship between poor mental health and the probability of any health expenditure and total expenditure conditional on any spending, even when adjusting for other confounding factors such as race/ethnicity, sex, age, educational attainment, insurance status, and some regional characteristics. Our results suggest that psychological distress and SRMH may represent potential pathways linking poor mental health to increased health care expenditure. Further research exploring the nuances of these relationships may aid researchers, practitioners, and policy makers in addressing issues of inflated health care expenditure in populations at risk for poor mental health.

Objectives The aim of the study is to expand knowledge about predictors of the self-rated health and mental health in fifty-year-old women. The study exploring links between self-rated mental/health and optimism, self-esteem, acceptance of the changes in physical look and some sociodemographic factors. Methods Participants in this study were 209 women aged 50 to 59. A single-items measures of self-rated health and mental health were used. Self-esteem was measured through the Rosenberg Self-Esteem Scale; optimism through the OPEB questionnaire; acceptance of the changes in physical look was rated by respondents on a seven-point scale. Participants were also asked about weight loss attempts, the amount of leisure time, and going on vacation during the last year. Results Predictors of the self-rated mental health in women in the age range of 50 to 59 were: acceptance of the changes in physical look, self-esteem and optimism. Predictors of the self-rated health were: optimism and acceptance of the changes in physical look. Conclusion Optimism and acceptance of the changes in physical look seem to be important factors that may impact subjective health both physical and mental of women in their 50s. The role of the leisure time and vacation in instilling the subjective health requires further investigation. PMID:26793678

Self-rated general health is one element of the standard health assessment required of U.S. military service members upon completion of major deployments. A cohort study of 22,229 male U.S. Army and Air Force personnel returning from Europe or Southwest Asia in 2000 used survival analysis methods and Cox proportional hazard models to examine postdeployment self-rated health (SRH) status and subsequent hospitalization, separation, and ambulatory care visits. Self-rated health was fair/poor for 1.5% and good for 20.4%; 11% documented at least one health concern. During 30,433 person-years of follow-up (median, 1.5 person-years), there were 22.8 hospitalizations per 1,000 person-years and 4.0 ambulatory care visits per person-years. After adjustment, deployers with fair/poor SRH had an increased risk for hospitalization (hazard ratio [HRI, 1.6; 95% confidence interval [CI], 1.0,2.7); the risk was lower for those with good SRH (HR, 1.3; 95% CI,1.1,1.5). Deployers with fair/poor SRH health had an increased risk for illness-related ambulatory care visits (HR, 1.8, 95%; CI, 1.6,2.1) and administrative visits (HR, 1.4; 95% CI, 1.1,1.7), but not injury-related visits (HR, 1.2; 95% CI, 0.8,1.7). Self-reported low health status and other health concerns identify military members with higher levels of health care needs following return from major deployments.

The erosion of social capital in more unequal societies is one mechanism for the association between income inequality and health. However, there are relatively few multi-level studies on the relation between income inequality, social capital and health outcomes. Existing studies have not used different types of health outcomes, such as dental status, a life-course measure of dental disease reflecting physical function in older adults, and self-rated health, which reflects current health status. The objective of this study was to assess whether individual and community social capital attenuated the associations between income inequality and two disparate health outcomes, self-rated health and dental status in Japan. Self-administered questionnaires were mailed to subjects in an ongoing Japanese prospective cohort study, the Aichi Gerontological Evaluation Study Project in 2003. Responses in Aichi, Japan, obtained from 5715 subjects and 3451 were included in the final analysis. The Gini coefficient was used as a measure of income inequality. Trust and volunteering were used as cognitive and structural individual-level social capital measures. Rates of subjects reporting mistrust and non-volunteering in each local district were used as cognitive and structural community-level social capital variables respectively. The covariates were sex, age, marital status, education, individual- and community-level equivalent income and smoking status. Dichotomized responses of self-rated health and number of remaining teeth were used as outcomes in multi-level logistic regression models. Income inequality was significantly associated with poor dental status and marginally significantly associated with poor self-rated health. Community-level structural social capital attenuated the covariate-adjusted odds ratio of income inequality for self-rated health by 16% whereas the association between income inequality and dental status was not substantially changed by any social capital

The purpose of this study is to develop and test a conceptual model that assesses the following theoretical linkages: (1) people who go to church more often tend to receive more spiritual support from fellow church members (i.e., encouragement to adopt religious teachings and principles); (2) individuals who get more frequent spiritual support are more likely to be humble; and (3) people with greater humility tend to rate their health more favorably. The data come from the third wave of a nationwide longitudinal survey of older adults. The data provide support for each of the conceptual linkages identified above.

Citizenship facilitates home ownership, which promotes access to additional resources and structures social context, factors that improve the health of individuals and communities. The objective of this study was to examine whether citizenship moderated the association between homeownership and self-rated health. We used multivariate logistic regression models and propensity score matching techniques to examine this association using pooled years 2000-2010 of the Medical Expenditure Panel Survey data linked with the National Health Interview Survey to examine U.S. adults aged 18 and older (N=170,429). Rates of fair/poor health among homeowners vs. non-homeowners were comparable for foreign-born non-citizens. However, native- and foreign-born citizen non-homeowners showed significantly higher rates of reporting fair/poor health, with native-born citizens having the highest rates of poor health. While homeownership is protective for self-rated health, not meeting the "American Dream" of home ownership may be embodied more in the health of native-born citizens as "failure" and translate into poorer self-rated health. However, the economic privileges of homeownership and its association with better self-rated health are limited to citizens. Non-citizens may be disadvantaged despite socioeconomic position, particularly wealth as considered by homeownership, placing citizenship at the forefront as the most proximate and important burden besides socioeconomic status that needs further investigation as a fundamental health determinant.

Background China’s rapidly changing economic landscape has led to widening social inequalities. Occupational status in terms of occupational type and prestige may reflect these socio-structural shifts of social position and be more predictive of self-rated health status than income and education, which may only reflect more gradual acquisitions of social status over time. The goals of this study were to understand the role of occupational status in predicting self-rated health, which is well known to be associated with long-term mortality, as well as compare the occupational status to the other major socioeconomic indicators of income and education. Methods Data from the 2010 baseline surveys of the China Family Panel Studies, which utilized multi-stage probability sampling with implicit stratification was used. Logistic regression was used to examine the relationship of various socioeconomic indicators (i.e. occupational status, income, and education) with self-rated health as the primary outcome of interest. A series of models considered the associations of occupational category or occupational prestige with self-rated health. Results The final sample consisted of 14,367 employed adults aged 18–60, which was nationally representative of working adults in China. We found that occupation was not a major predictor of self-rated health in China when age, ethnicity, location, marital status, physical and mental health status were controlled for, with the exception of women working in lower grade management and professional jobs (OR = 1.82, 95% CI: 1.03–3.22). In comparison, income followed by education exhibited greater association with self-rated health. The highest income group had the least probability to report poor health (In men: OR = 0.30, 95% CI: 0.21–0.43. In women: OR = 0.44, 95% CI: 0.26–0.73). People educated with junior high school had better self-rated health than those with primary and below education level (In men: OR = 0.62, 95% CI: 0.50–0

The prevalence of different neighborhood environmental stressors and associations between the stressors and self-rated health are described in a representative sample of 2,077 individuals, aged 18-85 years, in southern Sri Lanka. Mosquito menace (69.4%), stray dog problems (26.8%), nuisance from neighbors (20.3%), and nuisance from drug users (18.7%) were found to be the most prevalent environmental stressors. None of the stressors investigated were associated with self-rated physical health, but nuisance from neighbors, nuisance from drug users, shortage of water and having poor water/sewage drainage system were associated with self-rated mental health among the respondents.

Objective To investigate factors associated with tourism experiences, and the association between tourism experiences and subsequent self-rated health. Method Multilevel logistic regression models and four waves of panel data from a large nationally representative survey of older adults in China were employed. Results Those who had a tourism experience tended to be younger, men, urban residents, have a higher socioeconomic status (SES), and frequently participate in leisure activities and exercise. However, controlling for SES, women were more likely than men to have a tourism experience. Notably, tourism was negatively associated with poor self-rated health and the association was robust to adjustments for a wide range of confounders. Discussion The net beneficial impact of tourism on self-rated health may operate through several mechanisms such as improvements in tourists’ cognitive functioning, healthy lifestyles, self-esteen, family and social relations, and psychological and spirtual well-being. Tourism participation is an effective way to promote healthy aging. PMID:26486781

The pathways between parenting behaviours, personality and physical health have all been separately studied. Prior research has paid little attention to the indirect effects of personality in the path between parenting behaviours and better health. The purpose of this study was to explore the mediational effects of conscientiousness on the relationships between parental socialisation of responsibility and self-rated health, and to examine potential age differences in this mediational pathway. In total, 736 female and 749 male members across Japan participated in this study. They were divided into three groups by age category: younger-, middle-aged and older-aged. Conscientiousness and health were concurrently rated, while parental socialisation of responsibility was retrospectively assessed. Our analyses revealed that parental socialisation of responsibility is positively associated with conscientiousness and self-rated health, that conscientiousness is positively associated with self-rated health, and that conscientiousness fully mediated the effect of parental socialisation of responsibility on self-rated health. The mediational links were consistent across younger, middle-aged and older-aged cohorts. Our findings suggest that greater parental socialisation of responsibility relates to higher conscientiousness, and consequently healthier adults. These findings imply that parental behaviours could be a plausible target for intervention to foster the development of conscientiousness and better health.

Americans' distrust in the health care system has increased in the past decades; however, little research has explored the impact of distrust on self-rated health and even less is known about whether neighborhood social environment plays a role in understanding the relationship between distrust and self-rated health. This study fills these gaps by investigating both the direct and moderating associations of neighborhood social environment with self-rated health. Our analysis is based on the 2008 Philadelphia Health Management Corporation's household survey and neighborhood-level data. Findings from multilevel logistic regression show that after controlling for individual- and neighborhood-level covariates, distrust is directly and adversely related to self-rated health, and that neighborhood social affluence and stability are directly and negatively associated with the odds of reporting poor/fair health. Neighborhood disadvantage and crime rates are not directly related to self-rated health, but increase the odds of having poor/fair health via distrust. Overall, our results suggest that macro-level actions can alter individual's perception of residential environment and lead to improved health. To improve the public health in an urban setting, rebuilding confidence in the health care system is integral, and the policies that help establish safe and cohesive neighborhoods may reduce the adverse effect of distrust on self-rated health.
Adverse economic shocks exert an influence on health perceptions, but little is known about the effect of sudden positive changes in a person's financial situation on self-rated health, particularly among low income people. This paper explores the association between an increase in the amount of non-contribution pensions, public cash transfers given to Costa Rican elderly of low socio-economic status (SES) and changes in self-rated health over time. The analysis is based on data from CRELES, the "Costa Rican Study on Longevity and Healthy Aging", which is based on a probabilistic sample of people born in 1945 or earlier, and living in Costa Rica by 2002. The fieldwork for the first and second waves of CRELES was conducted from 2004 to 2006, and from 2006 to 2008, respectively. The Costa Rican Government raised the amount of the non-contribution pension for the poor 100% before July 2007, and an additional 100% after that date. Due to the CRELES fieldwork schedule, the data have a natural quasi-experimental design, given that approximately half of CRELES respondents were interviewed before July 2007, independently of their status in receiving the public cash transfers. Using random effects ordered probit regression models, we find that people who experienced such increase report a greater improvement in self-rated health between waves than those who experienced a smaller increase and than the rest of the interviewees. Results suggest that increases in income may lead to a greater improvement in self-rated health.

This cross-sectional survey explored the depression status of new migrant women and its relationship with self-rated health in the Hong Kong Chinese context. A convenience sample of 68 migrant women volunteered to participate in the study. The data were collected by using the Problem Solving Inventory, the Center for Epidemiological Studies-Depression questionnaire, and a self-rated health scale. The respondents were found to have a lesser degree of problem-solving appraisal, compared with other populations, and almost half of the volunteers were found to be depressed. Approximately 50% of the women reported their general health as "excellent", "very good", or "good". The Pearson's correlation showed a positive significant correlation between problem-solving appraisal, depression, and self-rated health. The results of the regression analysis showed that family income, self-rated health, and problem-solving confidence are predictive factors of depression. Community nurses could consider using multidisciplinary interventions that focus on life-skills training in order to promote the psychological and general wellness of migrant women in addition to the use of counseling or medication interventions.

Background There is mounting evidence that discriminatory experiences can harm health. However, previous research has mainly focused on the health effects of racial discrimination in U.S. or European countries although there is pervasive discrimination by gender, age, education and other factors in Asian countries. Methods We analyzed the data from the 7th wave of Korean Labor and Income Panel Study to investigate the association between perceived discriminatory experience and poor self-rated health in South Korea. Perceived discriminatory experiences were measured in eight situations through a modified Experience of Discrimination questionnaire. In each of eight situations, the lifetime prevalence of perceived discriminatory experience was compared between men and women and the main causes of those experiences were identified separately by gender. After adjusting for potential confounders, we examined the association between perceived discriminatory experience and poor self-rated health in each of eight social situations and also checked the association using the number of situations of perceived discriminatory experiences. Results For both men and women, education level and age were the main sources of work-related perceived discriminatory experiences. Gender was one of the main causes among women across eight situations and more than 90% of women reported their gender as a main cause of discriminatory experience in getting higher education and at home. Discriminatory experiences in four situations were positively associated with poor self-rated health. The odds ratio for poor self-rated health for those exposed to one, two, three or four or more social situations of perceived discrimination were respectively 1.06 (95% CI : 0.87–1.29), 1.15 (95% CI : 0.96–1.55), 1.59 (95% CI : 1.19–2.14), and 1.78 (95% CI :1.26–2.51). Conclusion There is consistent association between perceived discriminatory experience and poor self-rated health across eight social

Purpose: I examine whether less favorable self-rated health raises the risk of outmigration more for young-old adults (aged 53-63 at the start of the 10-year longitudinal study in 1994) in nonmetro than metro counties and increases the odds that both groups of outmigrants will choose metro over nonmetro destinations. Finally, I examine whether…

Using previous data from a random sample of 300 single mothers from rural Alabama, multiple regression analysis indicated that food insecurity and employment status had a modest effect on self-rated health status, while educational attainment and income had the greatest effect. These variables explained 29% of the variance in health status. Social and economic policies that affect educational attainment and income distribution may have important consequences for health status in these rural areas.

Health literacy (HL) is a key determinant of health in a contemporary society characterized by abundant information. Previous studies have suggested that basic or functional HL is positively associated with health, whereas evidences on the association between health and communicative/critical HL are scarce. Furthermore, confounding by socioeconomic status on HL-health association has been poorly tested. Using cross-sectional data from a nationally representative community-based survey in Japan, we investigated whether communicative/critical HL is associated with self-rated health independent of socioeconomic status. A total of 1237 subjects participated in this study; the response rate was 62%. To measure communicative/critical HL, we used three questions assessing the respondents' ability to select, to communicate to others and to evaluate specific health-related information. Potential confounders included demographic factors, household income, employment status, and educational attainment. A multivariate model revealed that good self-reported health was significantly associated with younger age [odds ratio (OR), 0.99; 95% confidence interval (CI), 0.97-0.99], employment (OR, 2.89; 95% CI, 1.06-7.88) and higher communicative/critical HL scores (OR 2.75; 95%CI, 1.93-3.90). Respondents with lower education were likely to have poorer communicative/critical HL. These results imply that to close the health gap, policy interventions should focus on the promotion of HL among deprived sociodemographic groups.

Existing research has found a positive association between countries’ level of democratic governance and the health of their populations, although that research is limited by the use of data from small numbers of high-income countries or aggregate data that do not assess individual-level health outcomes. We extend prior research by using multilevel World Health Survey (2002-2004) data on 313,554 individuals in 67 countries, and find that the positive association between democratic governance and self-rated health persists after adjusting for both individual- and country-level confounders. However, the mechanisms linking democracy and self-rated health remain unclear. Individual-level measures of socioeconomic status, and country-level measures of economic inequality and investments in public health and education, do not significantly mediate the association between democratic governance and self-rated health. The persistent association between democratic governance and health suggests that the political organization of societies may be an important upstream determinant of population health. PMID:26356825

Aims Our study extends research on the social determinants of health by exploring the association between a new, potentially very significant dimension, cultural capital by type and self-rated health among low-income women living in outer Beirut, Lebanon. Methods Self-rated general health was assessed using household data from a cross-sectional survey of 1869 women, conducted in 2003. Three types of cultural capital were included: watching cultural TV programs, producing art (e.g., drawing, theatre performance) and consuming art or literature (e.g., attending exhibits, reading literary books). Associations between self-rated health status and types of cultural capital were assessed using odds ratios from binary logistic regression models. Results With the exception of art production, lack of cultural capital increased the odds of self-perceived poor health status adjusting for socio-demographics and other risk factors. The adjusted odds ratios were 1.86 (95% CI: 1.07 to 3.22) for watching cultural TV programs and 1.52 (95% CI: 1.12 to 2.06) for consuming art. As expected, health risk factors, age, social support and community of residence were also associated with health status. Conclusions Two types of cultural capital were strong predictors of self perceived health status among women living in poor urban communities, regardless of social capital, income and other relevant risk factors.

Many studies, but not all, suggest that immigrant health worsens with duration of residence in the U.S. Cohort effects may explain the inconsistent findings; not only are cohort effects confounded with duration, but the timing of entry into the US may also create qualitatively different migration experiences. The present study tests for duration and cohort patterns among Asian immigrants to the United States across six year-of-entry cohorts (pre-1980, 1981-1985, 1986-1990, 1991-1995, 1996-2000, 2001-2005). Data come from the Asian American sample (n=44,002) from the 1994-2009 waves of the National Health Interview Survey. The data show cohort differences for self-rated health, such that more recent cohorts showed improved baseline health compared to older cohorts. After accounting for cohorts, there was no significant change in self-rated health by duration. Older cohorts actually showed improving self-rated health with longer duration. Obesity showed the opposite pattern; there were no differences across cohorts, but duration in the United States correlated with higher obesity. These results imply that immigrant health is not simply an issue of duration and adaptation, but underscore the utility of considering cohorts as broader contexts of migration. Collectively, the results encourage future research that more carefully examines the etiological mechanisms that drive immigrant health. PMID:25879262

Objectives To evaluate ethnic group differences in the association between trauma exposure and health status among an ethnically diverse sample originating in Hawai‘i. Design Across a ten-year period (1998–2008), participants (N = 833) completed five waves of questionnaire assessments. Trauma exposure was measured retrospectively at the most recent assessment (wave 5), socioeconomic resources (educational attainment and employment status) were measured at wave 1, and self-rated health was measured at each of the five waves. Results Results indicated that greater exposure to trauma was associated with poorer self-rated health, as were lower educational attainment and lower work status. In addition there was ethnic group variation in health ratings, as well as in how strongly trauma exposure predicted health status. Specifically, within Filipino American and Native Hawaiian ethnic groups, there was a stronger negative association between trauma exposure and self-rated health. Conclusion These results suggest complex interrelations among trauma, ethnicity, socioeconomic status, and physical health. Further understanding these relations may have implications for medical and behavioral interventions in vulnerable populations. PMID:22732011

Background Biobehavioral correlates of self-rated health in pregnancy are largely unknown. Purpose The goals of this study were to examine, in pregnant women, associations of self-rated health with 1) demographics, objective health status, health behaviors and psychological factors and 2) serum inflammatory markers. Methods In the 2nd trimester of pregnancy, 101 women provided a blood sample, completed measures of psychosocial stress, health status, and health behaviors, and received a comprehensive periodontal examination. Results The following independently predicted poorer self-rated health: 1) greater psychological stress, 2) greater objective health diagnoses, 3) higher body mass index, and 4) past smoking (versus never smoking). Poorer self-rated health was associated with higher serum interleukin-1β (p = .02) and marginally higher macrophage migration inhibitory factor (p = .06). These relationships were not fully accounted for by behavioral/psychological factors. Conclusions This study provides novel data regarding factors influencing subjective ratings of health and the association of self-rated health with serum inflammatory markers in pregnant women.

Socioeconomic inequalities in health are well documented. Recently, researchers have shown interest in exploring the mechanisms by which measures of SES operate through it to impact SRH, such as material, psychosocial and behavioral factors. To examine the relationships between SES indicators and self-rated health (SRH); and to determine whether health behaviors and obesity mediate the association between SES indicators and SRH. A secondary analysis of data previously collected through the third survey of socioeconomic and health status of the Arab population in Israel, in which the SRH of 878 Arab-Israelis age 50 or older were analyzed using logistic regression. The results showed that higher education level and current employment in old age are associated with better SRH. However, neither subjective economic status nor family income was associated with SRH. Greater physical activity was found to be related to good\\very good SRH, while obesity was associated with less than good SRH. Finally, health behaviors (physical activity) and obesity were revealed as mediators between SES indicators (education and employment status) and SRH. The results highlight the importance of high education level and employment status in old age to reduce health inequalities. The findings also show that the relationship between SES and SRH can operate through behavioral mechanisms (i.e., physical activity) and their consequences (i.e., obesity), that can, however, be changed in old age.

This paper analyzes data from a nationally representative survey of adults in the United Kingdom (Understanding Society, N = 37,253) to explore the marital status/health nexus (using categories that include a measure of relationship distress) and to assess the role that sleep problems play as a potential mediator. Findings indicate how it is not just the "form" marital status takes but also the absence or presence of relationship distress that is essential to self-rated health. We demonstrate two further findings that: (1) sleep problems act as a mediator of the link between marital status/relationship distress and self-rated health, most notably for those in cohabiting relationships with medium/high distress or who have a history of relationship loss, and (2) the mediating role of sleep problems differs for divorced men and women.

Older Chinese immigrants are a growing population in the United States who experience multiple healthcare communication barriers such as limited English proficiency and low health literacy. Each of these obstacles has been associated with poor health outcomes but less is known about their effects in combination. This study examined the association between healthcare communication barriers and self-rated health among older Chinese immigrants. Cross-sectional survey data were obtained from 705 Chinese American immigrants ages 50-75 living in San Francisco, California. Communication barriers examined included spoken English proficiency, medical interpreter needs, and health literacy in written health information. The study sample (81 % females, mean age = 62) included 67 % who spoke English poorly or not at all, 34 % who reported needing a medical interpreter, and 37 % who reported "often" or "always" needing assistance to read health information. Two-thirds reported poor self-rated health; many reported having access to racial-concordant (74 %) and language-concordant (86 %) healthcare services. Both poor spoken English proficiency and low health literacy were associated with poor self-rated health, independent of other significant correlates (unemployment, chronic health conditions, and having a primary doctor who was ethnic Chinese). Results revealed that spoken English proficiency and print health literacy are independent communication barriers that are directly associated with health status among elderly Chinese American immigrants. Access to racial- or language-concordant health care services did not appear to resolve these barriers. These findings underscore the importance of addressing both spoken and written healthcare communication needs among older Chinese American immigrants.
Adverse economic shocks exert an influence on health perceptions, but little is known about the effect of sudden positive changes in a person’s financial situation on self-rated health, particularly among low income people. This paper explores the association between an increase in the amount of non-contribution pensions, public cash transfers given to Costa Rican elderly of low socio-economic status (SES) and changes in self-rated health over time. The analysis is based on data from CRELES, the “Costa Rican Study on Longevity and Healthy Aging”, which is based on a probabilistic sample of people born in 1945 or earlier, and living in Costa Rica by 2002. The fieldwork for the first and second waves of CRELES was conducted from 2004 to 2006, and from 2006 to 2008, respectively. The Costa Rican Government raised the amount of the non-contribution pension for the poor 100% before July 2007, and an additional 100% after that date. Due to the CRELES fieldwork schedule, the data have a natural quasi-experimental design, given that approximately half of CRELES respondents were interviewed before July 2007, independently of their status in receiving the public cash transfers. Using random effects ordered probit regression models, we find that people who experienced such increase report a greater improvement in self-rated health between waves than those who experienced a smaller increase and than the rest of the interviewees. Results suggest that increases in income may lead to a greater improvement in self-rated health. PMID:21440352

Despite recent declines, racial segregation remains a detriment to minority neighborhoods. However, existing research is inconclusive as to the effects racial segregation has on health. Some argue that racial segregation is related to poor health outcomes, whereas others suspect that racial segregation may actually lead to improved health for some minority communities. Even less is known about whether minority access to white neighborhoods improves health. We address these gaps with individual data from the 2010 Public Health Management Corporation's Southeastern Pennsylvania Household Health Survey and census tract data from the 2010 Decennial Census and the 2006-2010 American Community Survey. We implement logistic multilevel models to determine whether and how a resident's self-rated health is affected by the racial/ethnic segregation of their neighborhoods. Our key finding suggests that the effects of segregation on self-rated health depend on an individual's race/ethnicity, with blacks and Latino residents most likely to experience adverse effects. Particularly, minorities living in predominantly white communities have a significantly higher likelihood to report poor/fair health than they would in segregated minority neighborhoods. These findings make clear that access to white neighborhoods is not sufficient to improve minority health; fuller neighborhood integration is necessary to ensure all have health equity.

There exists controversy as to the impact gentrification of cities has on the well-being of minorities. Some accuse gentrification of causing health disparities for disadvantaged minority populations residing in neighborhoods that are changing as a result of these socioeconomic shifts. Past scholarship has suggested that fears of displacement and social isolation associated with gentrification lead to poorer minority health. However, there is a lack of research that directly links gentrification to minority health outcomes. We address this gap with individual data from the 2008 Philadelphia Health Management Corporation's Southeastern Pennsylvania Household Health Survey and census tract data from the 2000 Decennial Census and the 2006-2010 American Community Survey. We implement logistic multilevel models to determine whether and how a resident's self-rated health is affected by gentrification of their neighborhoods. We find that while gentrification does have a marginal effect improving self-rated health for neighborhood residents overall, it leads to worse health outcomes for Blacks. Accounting for racial change, while gentrification leading to increases in White population has no measurable effect on minority health, "Black gentrification" leads to marginally worse health outcomes for Black respondents. These results demonstrate the limitations that improvements of neighborhood socioeconomic character have in offsetting minority health disparities.

Background Although self-rated health has been extensively studied in community older people, its determinants have seldom been investigated in institutional settings. We carried out a cross-sectional study to describe the physical, mental, and social factors associated with self-rated health in nursing homes and other geriatric facilities. Methods A representative sample of 800 subjects 65 years of age and older living in 19 public and 30 private institutions of Madrid was randomly selected through stratified cluster sampling. Residents, caregivers, physicians, and nurses were interviewed by trained geriatricians using standardized instruments to assess self-rated health, chronic illnesses, functional capacity, cognitive status, depressive symptoms, vision and hearing problems, and social support. Results Of the 669 interviewed residents (response rate 84%), 55% rated their health as good or very good. There was no association with sex or age. Residents in private facilities and those who completed primary education had significantly better health perception. The adjusted odds ratio (95% confidence interval) for worse health perception was 1.18 (1.07–1.28) for each additional chronic condition, 2.37 (1.38–4.06) when comparing residents with moderate dependency to those functionally independent, and 10.45 (5.84–18.68) when comparing residents with moderate/severe depressive symptoms to those without symptoms. Visual problems were also associated with worse health perception. Similar results were obtained in subgroup analyses, except for inconsistencies in cognitively impaired individuals. Conclusion Chronic conditions, functional status, depressive symptoms and socioeconomic factors were the main determinants of perceived health among Spanish institutionalized elderly persons. Doubts remain about the proper assessment of subjective health in residents with altered cognition. PMID:18304308

Focusing on Asian Americans, Hawaiians, and Caucasians in Hawaii, this study contributes to the literature by examining (1) the geographical distributions of education in relation to self-rated general health at neighborhood levels, and (2) the individual variations in self-rated health by ethnicity and education at both individual and neighborhood levels. Using the 2007 Hawaii Health Survey with linked zip-code information, and applying GIS (Geographic Information System) and binary logistic regression models, this study found that (1) there are significant between ethnic differences in self-rated health in Hawaii, with Hawaiians being the most disadvantaged population compared to Japanese, Chinese, and Caucasians; (2) individual socioeconomic characteristics are all related to self-rated health, and education (in particular) mediates the Japanese vs. Hawaiian and Chinese vs. Hawaiian health differences; (3) the neighborhood level of education has an independent effect on self-rated health over and above individual characteristics for the whole sample and it partially mediates the between ethnic health differences; and (4) the relative importance of education to self-rated health is more significant and salient for Caucasians and Japanese/Chinese than for Filipinos and Hawaiians. In sum, this study not only demonstrates a geographical profile of health and education distributions in Hawaii, but also reveals significant mediating effects of education, at both individual and neighborhood levels, in explaining the between and within ethnic differentials in self-rated health.

To investigate adolescent students' self-rated health status and to identify the influencing factors that affect students' health status. A stratified cluster sampling method and the Self-assessed General Health Questionnaires were used to enroll 503 adolescent students from Sichuan Province, Southwest part of China. Most adolescent students perceived their self-rated health as “Fair” (29.4%), “Good” (52.1%), or “Very Good” (16.3%). Regarding the sleep quality, most of them rated them as “Fair” (24.9%), “Good” (43.1%), or “Very Good” (19.7%), but 59.7% students reported to sleep less than 8 hours a day, even a few reported to sleep less than 6 hours (4.4%) or more than 9 hours (9.7%). A considerable number of students (41.1%) reported that they “Never” or just “Occasionally” participated in appropriate sports or exercises. As to the dietary habit, a significant number of students (15.7%) reported that they “Never” or “Occasionally” have breakfast. Students from different administrative levels of schools (municipal level, county level, and township level) rated differently (P < 0.05) in terms of their self-rated health, Health Behaviors, Sleeping, Dietary behaviors, Safety Awareness, and Drinking and Smoking behaviors. In general, Chinese teenage students perceived their own health status as fairly good. However, attention needs to be paid to health problems of some of the students, such as lack of sleep and exercise and inadequate dietary habits, etc. More concerns need to be addressed to students from different administrative levels of schools, and strategies should be put forward accordingly.

Using baseline data from ELSA-Brasil (N = 15,105), we investigated whether subjective social status, measured using three 10-rung "ladders," is associated with self-rated health and smoking, independently of objective indicators of social position and depression symptoms. Additionally, we explored whether the magnitude of these associations varies according to the reference group. Subjective social status was independently associated with poor self-rated health and weakly associated with former smoking. The references used for social comparison did not change these associations significantly. Subjective social status, education, and income represent distinct aspects of social inequities, and the impact of each of these indicators on health is different.

Aim: This study examined the influence of the social context in which people live on self-ratings of their oral health. Method: This study involved a representative sample of 2,907 South African adults (≥16 years) who participated in the 2007 South African Social Attitude Survey (SASAS). We used the 2005 General Household Survey (n = 107,987 persons from 28,129 households) to obtain living environment characteristics of SASAS participants, including sources of water and energy, and household cell-phone ownership (a proxy measure for the social network available to them). Information obtained from SASAS included socio-demographic data, respondents’ level of trust in people, oral health behaviors and self-rated oral health. Results: Of the respondents, 76.3% self-rated their oral health as good. Social context influenced women’s self-rated oral health differently from that of men. Good self-rated oral health was significantly higher among non-smokers, employed respondents and women living in areas with higher household cell-phone ownership. Furthermore, trust and higher social position were associated with good self-rated oral health among men and women respectively. Overall, 55.1% and 18.3% of the variance in self-rated oral health were explained by factors operating at the individual and community levels respectively. Conclusion: The findings highlight the potential role of social capital in improving the population’s oral health. PMID:23202757
Background: To analyse time trends in self-rated health in older people by gender and age and examine disability in the time trends of self-rated health. Methods: The data used come from the Spanish National Health Surveys conducted in 2001, 2003, 2006 and 2011–12. Samples of adults aged 16 yr and older were selected. Multivariate logistic regression was used to assess the association between age, gender, socio-economic status, marital status, disability and self-rated health across period study. Results: Women exhibited lower (higher) prevalence of good self-rated health (disability) compared to men. The multivariate analysis for time trends found that good self-rated health increased from 2001 to 2012. Overall, variables associated with a lower likelihood of good self-rated health were: being married or living with a partner, lower educational level, and disability. Conclusion: Trends of good self-rated health differ by gender according to socio-demographic factors and the prevalence of disability. PMID:27141490

Self- assessed general health status is a commonly-used survey technique since it can be used as a predictor for several public health risks such as mortality, deprivation, and fear of crime or poverty. Therefore, it is a useful alternative measure to help assessing the public health situation of a neighborhood or town, and can be utilized by authorities in many decision support situations related to public health, budget allocation and general policy-making, among others. It can be considered as spatial decision problems, since both data location and spatial relationships make a prominent impact during the decision making process. This paper utilizes a recently-developed spatial intelligent decision system, named, Spatial RIMER(+), to model the self-rated health estimation decision problem using real data in the areas of Northern Ireland, UK. The goal is to learn from past or partial observations on self-rated health status to predict its future or neighborhood behavior and reference it in the map. Three scenarios in line of this goal are discussed in details, i.e., estimation of unknown, downscaling, and predictions over time. They are used to demonstrate the flexibility and applicability of the spatial decision support system and their positive capabilities in terms of accuracy, efficiency and visualization.

Despite growing research emphasis on understanding the health effects of ethnic discrimination, little work has focused on how such exposures may influence a woman's biology and health during pregnancy. Understanding such effects is important given evidence that maternal stress experience in pregnancy can have long term effects on offspring health. Here we present data evaluating the relationship between perceived discrimination, self-rated health, and the stress hormone cortisol measured in late pregnancy among a diverse sample of women living in Auckland, New Zealand (N = 55). We also evaluated possible intergenerational impacts of maternal discrimination on stress reactivity in a subset of offspring (N = 19). Pregnant women were recruited from two antenatal care clinics in Auckland. Women were met in their homes between 34 and 36 weeks gestation, during which time a prenatal stress questionnaire was administered and saliva samples (morning and evening from two days) were obtained. Offspring cortisol reactivity was assessed at the standard six week postnatal vaccination visit. We found that 34% of women reported having experienced ethnic discrimination, with minority and immigrant women being more likely to report being angry or upset in response to discrimination experience compared with NZ-born women of European descent. Women reporting discrimination experience had worse self-rated health, higher evening cortisol and gave birth to infants with higher cortisol reactivity, all independent of ethnicity and material deprivation. These findings suggest that discrimination experience can have biological impacts in pregnancy and across generations, potentially contributing to the ethnic gradient in health.

This study examined mechanisms of the effect of involuntary retirement on self-rated health and mental health among adults aged 50 or older. Using two waves of the Health and Retirement Study (2006 and 2010), we selected a sample of 1,195 individuals working for pay at baseline who responded to a lifestyle questionnaire in both waves. Regression-based path analyses were conducted to test the mediating effects of financial control, positive and negative family relationships, and social integration on the relationship between involuntary retirement and self-rated health and mental health. Results of mediation analyses indicated that transition to involuntary retirement was directly negatively associated with subsequent self-rated health and indirectly negatively associated with mental health via perception of less financial control. Voluntary retirement was indirectly positively associated with both self-rated and mental health via perception of more financial control. No significant direct or indirect effects of retirement were found when retirement was measured with an aggregate measure without specifying its voluntariness. Findings emphasize the importance of specifying the voluntariness of retirement and recognizing the heterogeneity in the mechanisms of involuntary and voluntary retirement.

OBJECTIVES: This study investigated whether objective health indicators explained lower self-rated health among Hispanics compared with non-Hispanic Whites. It also considered socioeconomic and cultural explanations. METHODS: Health ratings of 429 Hispanics and 583 non-Hispanic Whites aged 20 through 74 were analyzed with logistic regression. RESULTS: Illness indicators were found to be strongly correlated with self-rated health in both ethnic groups, but after such markers were controlled for, Hispanics remained 3.6 times more likely to report fair or poor health (95% confidence interval = 2.4, 5.3). Adjustment for socioeconomic factors accounted for a portion of Hispanics' lower health rating, but the strongest explanatory factor was acculturation. CONCLUSIONS: Because of cultural and economic influences on definitions of health, ethnic differences in self-assessed health may not accurately reflected patterns resulting from objective health measurements.

Background In epidemiological research, self-rated health is an independent predictor of mortality, cardiovascular diseases, and other critical outcomes. It is recommended for clinical use, but research is lacking. Aim To investigate what happens in consultations when the question ‘How would you assess your general health compared with others your own age?’ is posed. Design and setting Authentic consultations with GPs at health centres in Sweden. Method Thirty-three planned visits concerning diabetes, pain, or undiagnosed symptoms were voice-recorded. Dialogue regarding self-rated health was transcribed verbatim and analysed using a systematic text condensation method. Speaking time of patients and doctors was measured and the doctors’ assessment of the value of the question was documented in a short questionnaire. Results Two overarching themes are used to describe patients’ responses to the question. First, there was an immediate reaction, often expressing strong emotions, setting the tone of the dialogue and influencing the continued conversation. This was followed by reflection regarding their functional ability, management of illnesses and risks, and/or situation in life. The GPs maintained an attitude of active listening. They sometimes reported a slight increase in consultation time or feeling disturbed by the question, but mostly judged it as valuable, shedding additional light on the patients’ situation and making it easier to discuss difficulties and resources. The patients’ speaking time increased noticeably during this part of the consultation. Conclusion Asking patients to comparatively self-rate their health is an effective tool in general practice.

Objective Self-rated health (SRH) predicts mortality above and beyond objective health risks and as such comprises an important aspect of health. Established contributors to self-rated health include affect, age, and disease, but neither their dynamic nor their synergistic contributions to SRH have been comprehensively tested. Methods The present study employed older adults (N = 150; M age = 75 years) and a longitudinal design with 6-month waves over up to 5 years. Positive and negative affect (PA, NA), chronic disease, and SRH were assessed at each wave. Results In multilevel models with single predictors, older age, more chronic disease, and higher NA predicted worse SRH, whereas higher PA predicted better SRH. Affect predicted SRH both between and within people. In multilevel models with interactions between affect and age or disease, individual differences in NA predicted worse SRH primarily in older people. Within people, changes in NA were associated with changes in SRH, but more so in younger than in older people. Within people, changes in PA were associated with changes in SRH, but only when health was better than usual. Conclusions There were both dynamic and synergistic relationships between affect and SRH that could only emerge in a multilevel, multivariable design. In the case of NA, between-person, trait NA had the opposite relationship to SRH and age compared with within-person, state NA. Which component of this relationship predicts mortality is an important question for future research. PMID:23914813

Although there is increasing evidence supporting the associations between social capital and health, less is known of potential effects in Latin American countries. Our objective was to examine associations of different components of social capital with self-rated health in Colombia. The study had a cross-sectional design, using data of a survey applied to a nationally representative sample of 3025 respondents, conducted in 2004-2005. Stratified random sampling was performed, based on town size, urban/rural origin, age, and sex. Examined indicators of social capital were interpersonal trust, reciprocity, associational membership, non-electoral political participation, civic activities and volunteering. Principal components analysis including different indicators of social capital distinguished three components: structural-formal (associational membership and non-electoral political participation), structural-informal (civic activities and volunteering) and cognitive (interpersonal trust and reciprocity). Multilevel analyses showed no significant variations of self-rated health at the regional level. After adjusting for sociodemographic covariates, interpersonal trust was statistically significantly associated with lower odds of poor/fair health, as well as the cognitive social capital component. Members of farmers/agricultural or gender-related groups had higher odds of poor/fair health, respectively. Excluding these groups, however, associational membership was associated with lower odds of poor/fair health. Likewise, in Colombians with educational attainment higher than high school, reciprocity was associated with lower odds of fair/poor health. Nevertheless, among rural respondents non-electoral political participation was associated with worse health. In conclusion, cognitive social capital and associational membership were related to better health, and could represent important notions for health promotion.

In this study, we examine race/ethnic consciousness and its associations with experiences of racial discrimination and health in New Zealand. Racism is an important determinant of health and cause of ethnic inequities. However, conceptualising the mechanisms by which racism impacts on health requires racism to be contextualised within the broader social environment. Race/ethnic consciousness (how often people think about their race or ethnicity) is understood as part of a broader assessment of the 'racial climate'. Higher race/ethnic consciousness has been demonstrated among non-dominant racial/ethnic groups and linked to adverse health outcomes in a limited number of studies. We analysed data from the 2006/07 New Zealand Health Survey, a national population-based survey of New Zealand adults, to examine the distribution of ethnic consciousness by ethnicity, and its association with individual experiences of racial discrimination and self-rated health. Findings showed that European respondents were least likely to report thinking about their ethnicity, with people from non-European ethnic groupings all reporting relatively higher ethnic consciousness. Higher ethnic consciousness was associated with an increased likelihood of reporting experience of racial discrimination for all ethnic groupings and was also associated with fair/poor self-rated health after adjusting for age, sex and ethnicity. However, this difference in health was no longer evident after further adjustment for socioeconomic position and individual experience of racial discrimination. Our study suggests different experiences of racialised social environments by ethnicity in New Zealand and that, at an individual level, ethnic consciousness is related to experiences of racial discrimination. However, the relationship with health is less clear and needs further investigation with research to better understand the racialised social relations that create and maintain ethnic inequities in health in

Mental health can be influenced by a number of neighbourhood physical and social environmental characteristics. We aimed to determine whether urban sprawl (based on population density) in Sydney, Australia, is associated with self-rated health and psychological distress. We used a cross-sectional multilevel study design. Individual level data on self-rated health and psychological distress were obtained from the 2006 and 2007 NSW Population Health Survey. We did not find significant associations between urban sprawl and self-rated health and psychological distress after controlling for individual and area level covariates. However, positive neighbourhood factors were generally associated with better self-rated health and lower psychological distress but few of these associations were statistically significant.

Few studies have considered the work environment in relation to workplace conflicts and those who have been published have included relatively few psychosocial work environment factors. Little research has been published on the consequences of workplace conflicts in terms of employee health. In this study, the statistical relationships between work and workplace characteristics on one hand and conflicts on the other hand are examined. In addition, the relationship between conflicts at work and self-rated health are described. The study population was derived from the Swedish Longitudinal Occupational Survey of Health (SLOSH) 2006; n=5,141. Among employees at workplaces with more than 20 employees (n=3,341), 1,126 (33.7%) responded that they had been involved in some type of conflict during the two years preceding the survey. Among the work and workplace characteristics studied, the following factors were independently associated with increased likelihood of ongoing conflicts: Conflicting demands, emotional demands, risk of transfer or dismissal, poor promotion prospects, high level of employee influence and good freedom of expression. Factors that decreased the likelihood of ongoing conflicts were: Good resources, good relations with management, good confidence in management, good procedural justice (fairness of decisions) and good social support. After adjustment for socioeconomic conditions the odds ratio for low self-rated health associated with ongoing conflict at work was 2.09 (1.60-2.74). The results provide a good starting point for intervention and prevention work.

Objective: By 2030, older adults will account for 20% of the U.S. population. Over 80% of older adults live in urban areas. This study examines associations between neighborhood environment and self-rated health (SRH) among urban older adults. Methods: We selected 217 individuals aged 65+ living in a deindustrialized Midwestern city who answered questions on the 2009 Speak to Your Health survey. The relationship between neighborhood environment and self-rated health (SRH) was analyzed using regression and GIS models. Neighborhood variables included social support and participation, perceived racism and crime. Additional models included actual crime indices to compare differences between perceived and actual crime. Results: Seniors who have poor SRH are 21% more likely to report fear of crime than seniors with excellent SRH (p = 0.01). Additional analyses revealed Black seniors are 7% less likely to participate in social activities (p = 0.005) and 4% more likely to report experiencing racism (p < 0.001). Discussion: Given the increasing numbers of older adults living in urban neighborhoods, studies such as this one are important for well-being among seniors. Mitigating environmental influences in the neighborhood which are associated with poor SRH may allow urban older adults to maintain health and reduce disability. PMID:26703659

This research evaluated the association between women's self-rated health and a number of socioeconomic and environmental health indicators relating to drinking water services in an underserved Lebanese community. A population-based, cross-sectional survey using interviews was adopted to obtain information from female homemakers of 2,223 households in the town of Bebnine, Lebanon. The questionnaire included indicators on self-rated health, satisfaction with water quality, source of drinking water, occurrence of diarrhea, and socioeconomic variables, such as education, occupation, and perceived economic status. Self-rated health was categorized as poor, fair, and good. Odds ratios for poor and fair compared to good self-rated health values were calculated using multinomial logistic regression. A total of 712 women (32%) reported poor self-rated health. Women who perceived their household income to be worse than others in town were four times as likely to report poor health. Compared to women who were satisfied with drinking water quality, dissatisfied women were 42% more likely to report poor health. Women living in households reporting recent episodes of diarrheal illness had poorer health ratings than those without. The findings suggest a positive relationship between individual perceptions of water quality and self-rated health. Community concerns over their surrounding environment serve as a primary guide for infrastructural development and government policy.

Three main opposing camps exist over how social capital relates to population health, namely the social support perspective, the inequality thesis, and the political economy approach. The distinction among bonding, bridging, and linking social capital probably helps close the debates between these three camps, which is rarely investigated in existing literatures. Moreover, although self-rated health is a frequently used health indicator in studies on the relationship between social capital and health, the interpersonal incomparability of this measure has been largely neglected. This study has two main objectives. Firstly, we aim to investigate the relationship between bonding, bridging, and linking social capital and self-rated health among Chinese adults. Secondly, we aim to improve the interpersonal comparability in self-rated health measurement. We use data from a nationally representative survey in China. Self-rated health was adjusted using the anchoring vignettes technique to improve comparability. Two-level ordinal logistic regression was performed to model the association between social capital and self-rated health at both individual and community levels. The interaction between residence and social capital was included to examine urban/rural disparities in the relationship. We found that most social capital indicators had a significant relationship with adjusted self-rated health of Chinese adults, but the relationships were mixed. Individual-level bonding, linking social capital, and community-level bridging social capital were positively related with health. Significant urban/rural disparities appeared in the association between community-level bonding, linking social capital, and adjusted self-rated health. For example, people living in communities with higher bonding social capital tended to report poorer adjusted self-rated health in urban areas, but the opposite tendency held for rural areas. Furthermore, the comparison between multivariate analyses

Despite a vast improvement in the survival of people living with HIV (PLHIV) since the introduction of combination antiretroviral treatment (cART), little change in the self-rated health of PLHIV has been observed since the introduction of cART in Australia. Difficulties with attaining employment or achieving financial security have been noted as some of the key challenges still facing PLHIV in the post-cART era. As a result, we investigated the independent association of a number of key social determinants of health with self-rated health among HIV-positive gay and bisexual men in Australia. Data from two recent national, cross-sectional surveys of PLHIV (the HIV Futures 5 and 6 surveys) were used. Logistic regression was used to assess the independent association of ethnicity, region of residence, education level, employment status, after-tax income, experience of HIV-related discrimination, level of social support, relationship status and recent sexual activity with reporting good-excellent self-rated health, after adjusting for clinical factors and other social determinants of health. Multiple imputation was used to estimate missing data for variables with >5% missing data. Of the 1713 HIV-positive gay/bisexual men who responded to the HIV Futures 5 and 6 surveys, information on self-rated health was available for 99.3%. Close to three-quarters of these respondents (72.1%) reported their self-rated health as good or excellent; the remainder (27.9%) reported their self-rated health as poor or fair. In multivariable analysis involving 89.3% of respondents, being employed, reporting recent sexual activity, a greater number of sources of social support and a higher weekly after-tax income were found to be independently associated with reporting good-excellent self-rated health. Despite the inability of this study to detect causal associations, addressing barriers to employment and sexual activity, and mechanisms to increase social support, is likely to have

This paper examines the association between cultural capital and self-rated psychosocial health among poor, ever-married Lebanese women living in an urban context. Both self-rated general and mental health status were assessed using data from a cross-sectional survey of 1,869 women conducted in 2003. Associations between self-rated general and mental health status and cultural capital were obtained using chi (2) tests and odds ratios from binary logistic regression models. Cultural capital had significant associations with self-perceived general and mental health status net of the effects of social capital, SES, demographics, community and health risk factors. For example, the odds ratios for poor general and mental health associated with low cultural capital were 4.5 (CI: 2.95-6.95) and 2.9 (CI: 2.09-4.05), respectively, as compared to participants with high cultural capital. As expected, health risk factors were significantly associated with both measures of health status. However, demographic and community variables were associated with general health but not with mental health status. The findings pertaining to social capital and measures of SES were mixed. Cultural capital was a powerful and significant predictor of self-perceived general and mental health among women living in poor urban communities.

Background The deprived physical environments present in slums are well-known to have adverse health effects on their residents. However, little is known about the health effects of the social environments in slums. Moreover, neighbourhood quantitative spatial analyses of the mental health status of slum residents are still rare. The aim of this paper is to study self-rated mental health data in several slums of Dhaka, Bangladesh, by accounting for neighbourhood social and physical associations using spatial statistics. We hypothesised that mental health would show a significant spatial pattern in different population groups, and that the spatial patterns would relate to spatially-correlated health-determining factors (HDF). Methods We applied a spatial epidemiological approach, including non-spatial ANOVA/ANCOVA, as well as global and local univariate and bivariate Moran's I statistics. The WHO-5 Well-being Index was used as a measure of self-rated mental health. Results We found that poor mental health (WHO-5 scores < 13) among the adult population (age ≥15) was prevalent in all slum settlements. We detected spatially autocorrelated WHO-5 scores (i.e., spatial clusters of poor and good mental health among different population groups). Further, we detected spatial associations between mental health and housing quality, sanitation, income generation, environmental health knowledge, education, age, gender, flood non-affectedness, and selected properties of the natural environment. Conclusions Spatial patterns of mental health were detected and could be partly explained by spatially correlated HDF. We thereby showed that the socio-physical neighbourhood was significantly associated with health status, i.e., mental health at one location was spatially dependent on the mental health and HDF prevalent at neighbouring locations. Furthermore, the spatial patterns point to severe health disparities both within and between the slums. In addition to examining health

Extensive evidence leads us to expect that health disparities by race and socioeconomic status found in one generation might be reproduced in the next. To the extent that this occurs it is important to assess life course processes responsible for the reproduction. Prospective evidence concerning such life course processes is hard to come by as it requires long-term follow-up of individuals from childhood through adult life. We present data from the Child Health and Development Disparities study that provides evidence relevant to this issue with respect to self-rated health. Mothers and offspring recruited in California's Bay Area between 1959 and 1967 were assessed during pregnancy with follow-up exams of offspring along with in-person interviews with mothers (at offspring ages 5, 9–11, 15–17) and offspring (at ages 15–17, ~50). Available data allow us to assess the importance of three potential life course pathways in the reproduction of inequalities in self-rated health – socioeconomic pathways, cognitive pathways and pathways involving emerging health itself. As expected we found that race and SES disparities in SRH are reproduced across generations. They are evident in mothers, not strong or significant in offspring at 15–17, but present once again in offspring at age ~50. Concerning potential pathways, we found that indicators of child health were related to adult SRH and played some role in accounting for race but not SES disparities in adult SRH. Cognitive abilities were unrelated to adult SRH with childhood SES controlled. Childhood SES was associated with adult SRH independent of other childhood factors and is reduced to non-significance only when offspring college attainment is controlled. Race and SES disparities in self-reported health in one generation are re-expressed in the next with strongest support for SES pathways in this transmission. PMID:27987434

As part of a prospective cohort study of 1354 female and 347 male healthcare personnel, we examined the stability of subjective social status over ~7 months and the prospective association between subjective social status and self-rated health status. Most (82%) subjective social status ratings were stable (within ±1 point). Lower baseline subjective social status among healthcare personnel was associated with more subsequent reports of fatigue and headache and worsening global self-rated health status. Healthcare personnel who placed themselves on the bottom half of the subjective social status ladder were four times more likely to experience a decline in global self-rated health status and half as likely to improve to excellent self-rated health status.

This study was an investigation of prevalence and associations between self-rated health and working conditions for small-scale enterprisers in a county in Sweden. A postal questionnaire was answered by 340 male and 153 female small-scale enterprisers in different sectors, with a response rate of 66%. For comparative purposes, data from a population study of 1,699 employees in private companies was included in the analyses. Differences were tested by Chi(2)-test and associations were presented as odds ratios (OR) with a 95% confidence interval (95% CI). The frequency of health problems in male enterprisers was higher than in employees in the private sector, while the frequency of health problems in female enterprisers was equal to that of the control employees. The main findings highlighted that male enterprisers reported higher rate of health problems and female enterprisers equal rate compared with employees in the private sector. Enterprisers stated musculoskeletal pain (women 59%, men 56%) and mental health problems (women 47%, men 45%) as the most frequent health problems. Poor job satisfaction, reported by 17% of the females and 20% of the male enterprisers, revealed an OR of 10.42 (95% CI 5.78-18.77) for poor general health. For the enterprisers, the most frequent complaints, musculoskeletal pain and mental health problems, were associated with poor job satisfaction and poor physical work environment. An association between poor general health and working as an enterpriser remained after adjusting for working conditions, sex and age.

Focusing on Asian Americans, this study examines how self-rated physical and mental health depends on the layered social connections (including 4 types: family cohesion, relative support, friend support, and neighborhood cohesion), socioeconomic status, and immigration-related factors (including nativity, length of residence in the U.S., and proficiency of the English language). It draws on the 2002-2003 National Latino and Asian American Study, a nationally representative household survey of Latino and Asian Americans. Findings of this study include: (1) there are significant differences in self-rated physical health among Asian Americans of different national origin, but their self-rated physical health differences diminish after indicators of socioeconomic status and immigration-related factors are considered; (2) four types of social connections are all related to the self-rated physical and mental health of Asian Americans, but the patterns of the associations as well as the mechanisms linking the associations vary; and (3) family cohesion has independent and direct effects on both self-rated physical and mental health over and above controls and mediators, whereas the effects of other social connection measures are partially mediated by socioeconomic status and immigration-related factors. In sum, this study indicates the significant effects of social connections, socioeconomic status, and immigration-related factors on the self-rated physical and mental health of Asian Americans.

Purpose The cognitive, social, and biological transitions of adolescence suggest that subjective perceptions of social position based on the socioeconomic hierarchy may undergo important changes during this period, yet how such perceptions develop is poorly understood and no studies assess if changes in such perceptions influence adolescents’ health. This study describes adolescents’ subjective perceptions of familial socioeconomic status (SSS), how SSS changes over time, and how age, race, and objective socioeconomic status (SES) indicators influence SSS. In addition, the study determines if SSS independently influences adolescents’ self-rated health, an important predictor of morbidity and health service utilization. Methods 1179 non-Hispanic black and white baseline 7–12th graders from a Midwestern public school district completed a validated, teen-specific measure of SSS annually for 4 consecutive years. A parent provided information on SES. Markov modeling assessed transitions in SSS over time. Results SSS declined with age (p=.001) and stabilized among older teens. In addition to age, SES and race, but not gender, were significant correlates of SSS, but the relationships between these factors were complex. In cross-sectional and longitudinal analyses, black teens from families with low parent education had higher SSS than white teens from similarly educated families, while white teens from highly educated families had higher SSS than black teens from highly educated families. Lower SSS and changes in SSS predicted poor self rated health even when adjusting for race and objective SES measures. Conclusion Subjective evaluations of socioeconomic status predict adolescents’ global health ratings even when adjusting for the sociodemographic factors which shape them. PMID:17950168

Purpose We determined the association of neighborhood foreclosure risk on the health status of a statewide sample of breast cancer survivors (n = 1047) and the extent to which covariates accounted for observed associations. Methods Measures of self-rated health and several covariates were obtained by telephone interview 1 year after diagnosis. We used the federal Housing and Urban Development agency's estimated census-tract foreclosure-abandonment-risk score and multilevel, logistic regression to determine the association of foreclosure risk (high, moderate versus low) with self-rated health (fair-poor versus good, very good, excellent) and whether covariates could explain the observed association. Results Women who resided in high-foreclosure-risk (HFR) areas were 2.39 times (95% CI: 1.83–3.13) more likely to report being in fair-poor health than women who lived in low-foreclosure-risk areas. The odds ratio (OR) was reduced for women who lived in high-foreclosure-risk versus low-foreclosure-risk areas after adjusting for income (HFR OR: 1.78; 95% CI: 1.01–3.15), physical activity (HFR OR: 1.74; 95% CI: 0.98–3.08), and perceived neighborhood conditions (HFR OR: 1.76; 95% CI: 1.02–3.05). Conclusions Breast cancer survivors who lived in census tracts with high- versus low-foreclosure risk reported poorer health status. This association was explained by differences in household income, physical activity, and perceived neighborhood conditions. PMID:21590510
The purpose of this study is to assess the effects of helping others on self-rated health in middle and late life. Data are from a nationwide sample of middle-aged and older adults (N=1154). The findings indicate that women and Blacks are more likely than men or Whites to help others. Moreover, the results suggest that people who attend church more often are especially likely to help others. The data further reveal that people who help others are more likely to have a greater sense of self-worth and people with more self-esteem, in turn, tend to rate their health in a more favorable way. The findings help clarify issues in the assessment of helping others in middle and late life.

Objective: This study examines associations between neighborhood environment and self-rated health (SRH) among urban older adults. Method: We selected 217 individuals aged 65+ living in a de-industrialized Midwestern city who answered questions on the 2009 Speak to Your Health survey. The relationship between neighborhood environment and SRH was analyzed using regression models. Neighborhood variables included social support and participation, perceived racism, and crime. Additional models included actual crime indices to compare differences between perceived and actual crime. Results: Seniors who have poor SRH are 21% more likely to report fear of crime than seniors with excellent SRH (p = .01). Additional analyses revealed Black seniors are 7% less likely to participate in social activities (p = .005) and 4% more likely to report experiencing racism (p < .001). Discussion: More than 80% of older adults live in urban areas. By 2030, older adults will account for 20% of the U.S.

Education's benefits for individuals' health are well documented, but it is unclear whether health benefits also accrue from the education of others in important social relationships. We assess the extent to which individuals' own education combines with their spouse's education to influence self-rated health among married persons ages 25 and older in the United States (N = 337,846) with pooled data from the 1997-2010 National Health Interview Survey. Results from age and gender-specific models revealed that own education and spouse's education each share an inverse association with fair/poor self-rated health among married men and women. Controlling for spousal education substantially attenuated the association between individuals' own education and fair/poor self-rated health and the reduction in this association was greater for married women than married men. The results also suggest that husbands' education is more important for wives' self-rated health than vice versa. Spousal education particularly was important for married women ages 45-64. Overall, the results imply that individuals' own education and spousal education combine to influence self-rated health within marriage. The results highlight the importance of shared resources in marriage for producing health.
This paper evaluates racial/ethnic differences in self-rated mental health for adults in the United States, while controlling for demographic and socioeconomic characteristics as well as length of stay in the country. Using data from the 2010 National Health Interview Survey Cancer Control Supplement (NHIS-CCS), binomial logistic regression models are fit to estimate the association between race/ethnicity and poor/fair self-reported mental health among US Adults. The size of the analytical sample was 22,844 persons. Overall prevalence of poor/fair self-rated mental health was 7.72%, with lower prevalence among Hispanics (6.93%). Non-Hispanic blacks had the highest prevalence (10.38%). After controls for socioeconomic characteristics are incorporated in the models, Hispanics were found to have a lower probability of reporting poor/fair self-rated mental health in comparison to non-Hispanic whites (OR = 0.70; 95% CI [0.55–0.90]). No difference was found for other minority groups when compared to the reference group in the final model. Contrary to global self-rated health, Hispanics were found to have a lower probability of reporting poor/fair self-rated mental health in comparison to non-Hispanic whites. No difference was found for non-Hispanic blacks when they were compared to non-Hispanic whites. Self-rated mental health is therefore one case of a self-rating of health in which evidence supporting the epidemiological paradox is found among adults in the United States. PMID:27688982

Using a national sample of single mothers from the 2007 and 2009 waves of the Panel Study of Income Dynamics, this study examined the effects of multiple employment statuses on the selfrated health of single mothers during the recent economic recession. Unlike other studies, the current study minimized selection bias by controlling for prior self-rated health, in addition to other predisposing factors, enabling factors, and need factors. We found that underemployment, but not unemployment, is associated with lower levels of self-rated health of single mothers. Results further indicate that the 25-39 age range (compared to the 18-24 age range), lower family income, prior lower self-rated health, more chronic diseases, and binge drinking place single mothers at an increased risk of lower levels of self-rated health. In contrast, strength-building physical activity is significantly associated with higher levels of self-rated health. Implications for health care policy and social work practice are drawn from the results.

In this study we conduct a multilevel analysis to investigate the association between regional income inequality and self-rated health in Japan, based on two nationwide surveys. We confirm that there is a significant association between area-level income inequality and individual-level health assessment. We also find that health assessment tends to be more sensitive to income inequality among lower income individuals, and to degree of area-level poverty, than income inequality for the society as a whole. In addition, we examine how individuals are averse to inequality, based on the observed association between inequality and self-rated health.
Background Loneliness is associated with peer victimization, and the two adverse experiences are both related to ill health in childhood and adolescence. There is, however, a lack of knowledge on the importance of loneliness among victimized children. Therefore, possible modifying effects of loneliness on victimized school children’s self-rated health were assessed. Methods A population based cross-section study included 419 children in grades 1–10 from five schools. The prevalence of loneliness and victimization across grades was analyzed by linear test for trend, and associations of the adverse experiences with four health symptoms (sadness, anxiety, stomach ache, and headache) were estimated by logistic regression. Results In crude regression analysis, both victimization and loneliness showed positive associations with all the four health symptoms. However, in multivariable analysis, the associations of victimization with health symptoms were fully attenuated except for headache. In contrast, loneliness retained about the same strength of associations in the multivariable analysis as in the crude analysis. More detailed analyses demonstrated that children who reported both victimization and loneliness had three to seven times higher prevalence of health symptoms compared to children who reported neither victimization nor loneliness (the reference group). Rather surprisingly, victimized children who reported no loneliness did not have any higher prevalence of health symptoms than the reference group, whereas lonely children without experiences of victimization had almost the same prevalence of health symptoms (except for stomach ache) as children who were both victimized and lonely. Conclusions Adverse effects of loneliness need to be highlighted, and for victimized children, experiences of loneliness may be an especially harsh risk factor related to ill health. PMID:22643050
Abstract Objective Aiming at preparing the basis for evidence-based dental public health policy making in Slovenia, the objective of the study was to assess the strength of association between oral health status measured by the number of missing teeth and self-rated health (SRH). Methods The study was designed as a pooled individual-level data study from four national cross-sectional studies carried out in the period 2001-2012, based on CINDI Health Monitor methodology. Altogether, 34,412 participants were included. A logistic regression model with poor SRH as observed outcome and the number of teeth as explanatory factor (adjusted for selected biologic, socio-economic and health factors) was proposed. Results In the sample, women represented 55.7% and men 44.3%, median age was 45 years. Persons with more missing teeth more likely rated their health as poor. The association was persistent even when different confounding variables were included in the model. In the group with 1-5 missing teeth, in comparison to the group with none missing teeth, OR was 1.23 (p=0.049), whereas for the group with 6-10 missing teeth, OR was 1.32 (p=0.019); for the group with >10 missing teeth, but not all, OR was 1.77 (p<0.001), and for the group with all missing teeth, OR was 2.19 (p<0.001). Conclusions Study results showed clear association of SRH with dentate status, which confirms the oral-general health connection. This indicates the need for the development of proper dental public health policies for better oral health, and presents a new view on the importance of preserving teeth. PMID:28289473

Self-rated health (SRH) is an inclusive measure of public health that is correlated with quality of life and subsequent mortality. Extensive literature has identified multiple determinants of SRH in different populations. However, such studies on centenarians are scarce and parsimonious. Our objective is to identify SRH determinants in centenarians. This is a nationwide cross-sectional study on 400 Greek centenarians that was carried out between 2007 and 2010. SRH was evaluated by a simple question with a 5-point scale. Three categories of SRH were formed (very good/good/poor), which served as the dependent variable in multinomial regression models. Various sociodemographic, disease-related, lifestyle and psychosocial variables were assessed as candidate determinants of SRH. According to our results, SRH ratings among centenarians were better than that expected according to previous studies showing worse SRH ratings with increasing age in Greece. The 22.4% of the variance in SRH among centenarians was predicted by gender, habitat region and status, financial problems, disease presence and autonomy. Among lifestyle and psychosocial variables, obesity, good relationships with children, lack of feelings of loneliness, high optimism, adaptability and an internal health locus of control profile were independently associated with good SRH. These results indicate that SRH in individuals of extreme longevity were related to specific personal psychosocial factors that contribute to healthy aging and thus support the biopsychosocial model of health promotion.

Epidemiological evidence suggests that sleep duration and poor sleep are associated with mortality, as well as with a wide range of negative health outcomes. However, few studies have examined the association between sleep and self-rated health, particularly through the combination of sleep complaints. The objective of this study was to examine whether self-rated health is associated with sleep complaints, considering the combination of sleep duration, insomnia, and sleep sufficiency. This cross-sectional study was performed in the 18 largest public hospitals in the city of Rio de Janeiro, Brazil. A total of 2518 female nurses answered a self-filled multidimensional questionnaire. The adjusted odds ratios and 95% confidence intervals (CIs) estimated the chance of poor self-rated health in the presence of different combinations of sleep duration and quality. Compared with women who reported adequate sleep duration with no sleep quality complaints (reference group), the odds ratios (95% CI) for poor self-rated health were 1.79 (1.27–2.24) for those who reported only insufficient sleep, 1.85 (0.94–3.66) for only a short sleep duration, and 3.12 (1.94–5.01) for only insomnia. Compared with those who expressed all three complaints (short sleep duration, insomnia, and insufficient sleep), the odds ratio for poor self-rated health was 4.49 (3.25–6.22). Differences in the magnitude of the associations were observed, depending on the combination of sleep complaints. Because self-rated health is a consistent predictor of morbidity, these results reinforce the increasing awareness of the role of sleep in health and disease. Our findings contribute to the recognition of sleep as a public health matter that deserves to be better understood and addressed by policymakers. PMID:25961874

There is scarcity of research investigating the validity of self-report of attention deficit hyperactivity disorder (ADHD) symptoms compared to other informants, such as parents. This study aimed to compare the predictive associations of ADHD symptoms rated by parents and their children across adolescence on a range of adverse socioeconomic and health outcomes in early adulthood. Parent- and self-rated ADHD symptoms were assessed in 2960 individuals in early (13-14 years) and late adolescence (16-17 years). Logistic regression analyses were used to compare the associations between parent- and self-rated ADHD symptoms at both time points and adverse life outcomes in young adulthood obtained from Swedish national registries. Both parent- and self-ratings of ADHD symptoms were associated with increased risk for adverse outcomes, although associations of parent-ratings were more often statistically significant and were generally stronger (OR = 1.12-1.49, p < 0.05) than self-ratings (OR = 1.07-1.17, p < 0.05). After controlling for the other informant, parent-ratings of ADHD symptoms in both early and late adolescence significantly predicted academic and occupational failure, criminal convictions and traffic-related injuries, while self-ratings of ADHD symptoms only in late adolescence predicted substance use disorder and academic failure. Our findings suggest that both parent- and self-ratings of ADHD symptoms in adolescence provides valuable information on risk of future adverse socioeconomic and health outcomes, however, self-ratings are not valuable once parent-ratings have been taken into account in predicting most outcomes. Thus, clinicians and researchers should prioritize parent-ratings over self-ratings.

Objectives This paper examines the ethnic and gender differentials in high blood pressure (HBP), diabetes, coronary heart disease (CHD), arthritis and asthma among older people in Malaysia, and how these diseases along with other factors affect self-rated health. Differentials in the prevalence of non-communicable diseases among older people are examined in the context of socio-cultural perspectives in multi-ethnic Malaysia. Methods Data for this paper are obtained from the 2004 Malaysian Population and Family Survey. The survey covered a nationally representative sample of 3,406 persons aged 50 and over, comprising three main ethnic groups (Malays, Chinese and Indians) and all other indigenous groups. Bivariate analyses and hierarchical logistic regression were used in the analyses. Results Arthritis was the most common non-communicable disease (NCD), followed by HBP, diabetes, asthma and CHD. Older females were more likely than males to have arthritis and HBP, but males were more likely to have asthma. Diabetes and CHD were most prevalent among Indians, while arthritis and HBP were most prevalent among the Indigenous groups. Older people were more likely to report poor health if they suffered from NCD, especially CHD. Controlling for socio-economic, health and lifestyle factors, Chinese were least likely to report poor health, whereas Indians and Indigenous people were more likely to do so. Chinese that had HBP were more likely to report poor health compared to other ethnic groups with the same disease. Among those with arthritis, Indians were more likely to report poor health. Conclusion Perceived health status and prevalence of arthritis, HBP, diabetes, asthma and CHD varied widely across ethnic groups. Promotion of healthy lifestyle, early detection and timely intervention of NCDs affecting different ethnic groups and gender with socio-cultural orientations would go a long way in alleviating the debilitating effects of the common NCDs among older people.

The purpose of this study was to explore associations of spiritual well-being, spiritual perspective, and religiosity with self-rated health in a convenience sample of 340 adult Jordanian Arab Christians. Data were collected through church and community groups. Results indicated that spiritual well-being and religiosity were positively associated with self-rated health, but in the final regression model only spiritual well-being retained a significant association after controlling for the other spiritual and religious measures. In conclusion, spirituality and religiosity are important to Jordanian Arab Christians' health and well-being, and the implications for nursing practice are explored.

This study evaluated the associations between social and physical environments and self-rated health (SRH) for urban and rural Korean adults, using data from the Korean Community Health Survey (KCHS) of 199,790 participants (115,454 urban and 84,336 rural). The main dependent variable was SRH, while the primary independent variables were social and physical characteristics. Urban residents reported better SRH than did rural residents. Five social environmental variables (trust of neighbors, residence in the area for over 20 years, exchanging help with neighbors, friend and fellowship activities, contact with relatives and neighbors over five times per month) were more prevalent among rural residents. Satisfaction with physical environment was more common among rural residents, but satisfaction with traffic and healthcare facilities was more common among urban areas. After adjusting for relevant factors, positive associations between SRH and trust of neighbors, exchanging help with neighbors, participation in social activities or organizations, and physical environment existed in both rural and urban populations. Also, in both areas, there was no demonstrated association between SRH and years of residence or frequency of contact with relatives. Our findings suggest the existence of an association between social and physical factors and perceived health status among the general population of Korea.
The purpose of this study was to see if feelings of God-mediated control are associated with change in self-rated health over time. In the process, an effort was made to see if a sense of meaning in life and optimism mediated the relationship between God-mediated control and change in health. The following hypothesized relationships were contained in the conceptual model that was developed to evaluate these issues: (1) people who go to church more often tend to have stronger God-mediated control beliefs than individuals who do not attend worship services as often; (2) people with a strong sense of God-mediated control are more likely to find a sense of meaning in life and be more optimistic than individuals who do not have a strong sense of God-mediated control; (3) people who are optimistic and who have a strong sense of meaning in life will rate their health more favorably over time than individuals who are not optimistic, as well as individuals who have not found a sense of meaning in life. Data from a longitudinal nationwide survey of older adults provided support for each of these hypotheses.

Edentulism is associated with various adverse health outcomes but treatment options in low- and middle-income countries (LMICs) are limited. Data on its prevalence and its effect on mental health and overall-health is lacking, especially from LMICs. Self-reported data on complete edentulism obtained by standardized questionnaires on 201,953 adults aged ≥18 years from 50 countries which participated in the World Health Survey (WHS) 2002-2004 were analyzed. Age and sex-standarized edentulism prevalence ranged from 0.1% (95% CI = 0.0-0.3) (Myanmar) to 14.5% (95% CI = 13.1-15.9) (Zimbabwe), and 2.1% (95% CI = 1.5-3.0) (Ghana) to 32.3% (95% CI = 29.0-35.8) (Brazil) in the younger and older age groups respectively. Edentulism was significantly associated with depression (OR 1.57, 95% CI = 1.23-2.00) and poor self-rated health (OR 1.38, 95% CI = 1.03-1.83) in the younger group with no significant associations in the older age group. Our findings highlight the edentulism-related health loss in younger persons from LMICs. The relative burden of edentulism is likely to grow as populations age and live longer. Given its life-long nature and common risk factors with other NCDs, edentulism surveillance and prevention should be an integral part of the global agenda of NCD control.

Background Self-rated oral health is a valid and useful summary indicator of overall oral health status and quality of life. However, few studies on perception of oral health have been conducted among Japanese young adults. This study investigated whether oral health behavior, subjective oral symptoms, or clinical oral status were associated with self-rated oral health in Japanese young adults. Methods This cross-sectional survey included 2,087 students (1,183 males, 904 females), aged 18 and 19 years, at Okayama University, Japan. A self-administered questionnaire was distributed and an oral examination was performed. Results In a structural equation modeling analysis, the score of decayed, missing and filled teeth (DMFT) significantly affected self-rated oral health (p <0.05) and the effect size was highest. Malocclusion, subjective symptoms of temporomandibular disorders (TMD) and stomatitis, and poor oral health behavior significantly induced self-rated poor oral health with small effect sizes (p <0.05). Clinical periodontal conditions and Oral Hygiene Index-simplified were not related to self-rated oral health. Conclusion Self-rated oral health was influenced by subjective symptoms of TMD and stomatitis, oral health behavior, the score of DMFT, and malocclusion. The evaluation of these parameters may be a useful approach in routine dental examination to improve self-rated oral health in university students. PMID:24195632

A study described situations of later-life career disruption in older workers in Canada (n=2,592); large numbers had experienced job interruption or loss. Disruptions were significantly associated with self-ratings of poor health. However, the causal relationship between unemployment and poor health was complex. (Contains 49 references.) (JOW)

To examine associations between work–family conflict and self-rated health among Japanese workers and to determine whether the associations differed by household income. Data was derived from the Japan Public Health Center-based Prospective Study for the Next Generation in Saku area in 2011–2012 (7,663 men and 7,070 women). Multivariate odds ratios (ORs) and 95% confidence intervals (CIs) for poor self-rated health by work–family conflict consisting of two dimensions (work-to-family and family-to-work conflicts) were calculated by gender and household income. Multivariate ORs of high work-to-family and family-to-work conflicts for poor self-rated health were 2.46 (95% CI; 2.04–2.97) for men and 3.54 (95% CI; 2.92–4.30) for women, with reference to the low work-to-family and family-to-work conflicts (p-value for gender interaction = 0.02). Subgroup analysis indicated that health effects of work–family conflict were likely to be more evident in the low income group only among women. Work–family conflict was associated with poor self-rated health among middle-aged Japanese men and women; its health impact was relatively stronger among women, and particularly economically disadvantaged women.

Using 1996/1997 to 2000/2001 data from the Canadian National Longitudinal Survey of Children and Youth, this paper examines the effects of harassment on self-rated and mental health status among Canadian adolescents aged 16-17 years. Forty-six percent of the children experienced harassment and victimization (verbal aggression, threat, and physical harm/assault) at school and 40% outside of school. Harassment at school, rather than otherwise, was associated with poor health status and higher levels of depression even when previous health conditions and socio-demographic variables were held constant. The relationship between harassment and mental health is particularly pronounced among girls, immigrant children and those living in single-parent households. Given the sizable proportion of adolescents as victims of harassment at school and its significant relationship with both health status and depression, the issue warrants serious public health attention through school-based intervention programs.

The Great Recession of 2008 has led to elevated unemployment in Europe and thereby revitalised the question of causal health effects of unemployment. This article applies fixed effects regression models to longitudinal panel data drawn from the European Union Statistics on Income and Living Conditions for 28 European countries from 2008 to 2011, in order to investigate changes in self-rated health around the event of becoming unemployed. The results show that the correlation between unemployment and health is partly due to a decrease in self-rated health as people enter unemployment. Such health changes vary by country of domicile, and by individual age; older workers have a steeper decline than younger workers. Health changes after the unemployment spell reveal no indication of adverse health effects of unemployment duration. Overall, this study indicates some adverse health effects of unemployment in Europe--predominantly among older workers.

Objective The purpose of this study was to employ a multivariate approach to examine the correlates of self-rated health in a college sample of women, with particular emphasis on sexual assault history and related mental health outcomes. Participants A national sample of 2,000 female college students participated in a structured phone interview between January and June, 2006. Methods Interview modules assessed demographics, posttraumatic stress disorder, major depressive episode, substance use, rape experiences, and physical health. Results Logistic regression analyses showed that poor self-rated health was associated with low income (OR = 2.70), lifetime posttraumatic stress disorder (OR = 2.47), lifetime major depressive episode (OR = 2.56), past year illicit drug use (OR = 2.48), and multiple rape history (OR = 2.25). Conclusions These findings highlight the need for university mental health and medical service providers to assess for rape history, and to diagnose and treat related psychiatric problems in order to reduce physical morbidity.

Previous research suggests that green environments positively influence health. Several underlying mechanisms have been discussed; one of them is facilitation of social interaction. Further, greener neighborhoods may appear more aesthetic, contributing to satisfaction and well-being. Aim of this study was to analyze the association of residential surrounding greenness with self-rated health, using data from 4480 women and men aged 45-75 years that participated in the German population-based Heinz Nixdorf Recall study. We further aimed to explore the relationships of greenness and self-rated health with the neighborhood environment and social relations. Surrounding greenness was measured using the Normalized Difference Vegetation Index (NDVI) within 100 m around participants' residence. As a result, we found that with higher greenness, poor self-rated health decreased (adjusted OR 0.90, 95% CI 0.82-0.98; per 0.1 increase in NDVI), while neighborhood satisfaction (1.41, 1.23-1.61) and neighborhood social capital (1.22, 1.12-1.32) increased. Further, we observed inverse associations of neighborhood satisfaction (0.70, 0.52-0.94), perceived safety (0.36, 0.22-0.60), social satisfaction (0.43, 0.31-0.58), and neighborhood social capital (0.53, 0.44-0.64) with poor self-rated health. These results underline the importance of incorporating green elements into neighborhoods for health-promoting urban development strategies.

Although over 1.5 million African immigrants live in the US, few studies have examined the relationship of language acculturation to health outcomes among African immigrant adults. The primary objective of this research was to investigate the relationship between English proficiency and current self-rated health among African immigrant adults. Using a cross-sectional design, a secondary data analysis was performed on baseline data from the African immigrant adult subsample (n = 763) of the 2003 New Immigrant Survey, a longitudinal study of lawful permanent residents. Limited English proficiency (LEP), increased duration of US residence, older age at immigration, being male, less than 12 years of education, poor pre-migration health, and chronic disease were associated with good/fair/poor current self-rated health. Findings support consideration of pre-migration health and chronic disease in future acculturation and health studies, and provision of linguistically competent interventions for LEP African immigrants at risk for poor health outcomes.
Little is known about how different lifestyle factors mediate the relationship between socioeconomic status (SES) and health among middle-aged and older adults in Korea. Using data from the Korean Longitudinal Study of Aging, this study examined the direct effects of SES on self-rated health and how lifestyle factors mediate the relationships between SES and self-rated health. This study further tested whether the effects of SES and lifestyle factors differ as people age. The findings indicate that higher levels of income and education as well as not being in poverty predicted better self-rated health. Meanwhile, engaging in regular exercise and being underweight significantly mediated the relationship between education and self-rated health as well as between poverty and self-rated health. Finally, poverty and regular exercise had a greater impact on self-rated health in old age than in middle age. Implications for enhancing antipoverty policies and exercise programs are discussed.

Neighborhood problems constitute sources of chronic stress that may increase the risk of poor self-rated health. The associations of census tract level income and perceived neighborhood problems with self-rated health were examined in Florianópolis, Santa Catarina State, Brazil (1,720 adults). Odds ratios (OR) and their 95% confidence intervals (95%CI) of poor self-rated health were estimated through multilevel models. Residents in census tracts in the lower and intermediate tertiles of income reported poorer health than those in the highest tertile. OR of reporting poorer health was 2.44 (95%CI: 2.35- 2.54) in the higher tertile of social disorder (adjusting for mental health). The chances of reporting the poorer health with neighborhood problems ranged from 1.07 (95%CI: 1.03-1.11) to 2.02 (95%CI: 1.95-2.10) for the higher tertile of social disorder (physical health) and physical problem (health-related variables). Perceived neighborhood problems were independently associated with poor health. The perception of a neighborhood among its residents should be considered by health policymakers.

Health status is often analyzed in population surveys. Self-rated health (SRH) is a single-item summary measure of the perception of one's health. In Brazil, studies on the SRH of adolescents remain scarce, especially those aiming to understand the domains that compose this construct. Therefore, the aim of this study is to determine the prevalence of poor SRH and its associated factors among 11- to 13-year-olds and 14- to 17-year-olds living in a large urban center in Brazil. This cross-sectional study was conducted using a household survey across Belo Horizonte that included 1,042 adolescents. Stratified logistic regression models were used for each age group to assess the associations between worse SRH and the following variables: socio-demographic, social and family support, lifestyles, psychological health, and anthropometry. Approximately 11% (95% CIs = 8.7-13.6) of the studied adolescents rated their health as poor, and SHR decreased with age among males and females. This trend was more pronounced among girls (from 6.9% among 11- to 13-year-old girls to 16.9% among 14- to 17-year-old girls) than boys (from 8.3% among 11- to 13-year-old boys to 11% among 14- to 17-year-old boys). Worse SRH was associated with family support (as assessed by the absence of parent-adolescent conversations; odds ratio [OR] = 3.5 among 11- to 13-year-olds), family structure (OR = 2.8 among 14- to 17-year-olds), and argument reporting (OR = 8.2 among 14- to 17-year-olds). Among older adolescents, the consumption of fruit fewer than five times per week (OR = 2.4), life dissatisfaction (OR = 2.8), underweight status (OR = 6.7), and overweight status (OR = 2.7) were associated with poor SRH. As adolescents age, their universe expands from their relationship with their parents to include more complex issues, such as their lifestyles and life satisfaction. Therefore, these results suggest the importance of evaluating SRH across adolescent age groups and demonstrate the influence of the

Ability to predict and prevent incipient functional decline in older adults may help prolong independence. Cognition is related to everyday function and easily administered, sensitive cognitive tests may help identify at-risk individuals. Factors like depressive symptoms and self-rated health are also associated with functional ability and may be as important as cognition. The purpose of this study was to investigate the relationship between concurrent longitudinal changes in cognition, depression, self-rated health and everyday function in a well-defined cohort of healthy 85 year olds that were followed-up at the age of 90 in the Elderly in Linköping Screening Assessment 85 study. Regression analyses were used to determine if cognitive decline as assessed by global (the Mini-Mental State Examination) and domain specific (the Cognitive Assessment Battery, CAB) cognitive tests predicted functional decline in the context of changes in depressive symptoms and self-rated health. Results showed deterioration in most variables and as many as 83% of these community-dwelling elders experienced functional difficulties at the age of 90. Slowing-down of processing speed as assessed by the Symbol Digits Modality Test (included in the CAB) accounted for 14% of the variance in functional decline. Worsening self-rated health accounted for an additional 6%, but no other variables reached significance. These results are discussed with an eye to possible preventive interventions that may prolong independence for the steadily growing number of normally aging old-old citizens. PMID:27551749

Chronic musculoskeletal pain is widespread in the working population and leads to muscular fatigue, reduced work capacity, and fear of movement. While ergonomic intervention is the traditional approach to the problem, physical exercise may be an alternative strategy. This secondary analysis of a randomized controlled trial investigates the effect of strength training on muscular fatigue resistance and self-rated health among workers with chronic pain. Sixty-six slaughterhouse workers with chronic upper limb pain and work disability were randomly allocated to 10 weeks of strength training or usual care ergonomic training (control). At baseline and follow-up, participants performed a handgrip muscular fatigue test (time above 50% of maximal voluntary contraction force) with simultaneous recording of electromyography. Additionally, participants replied to a questionnaire regarding self-rated health and pain. Time to fatigue, muscle strength, hand/wrist pain, and self-rated health improved significantly more following strength training than usual care (all P < 0.05). Time to fatigue increased by 97% following strength training and this change was correlated to the reduction in fear avoidance (Spearman's rho = -0.40; P = 0.01). In conclusion, specific strength training improves muscular fatigue resistance and self-rated health and reduces pain of the hand/wrist in manual workers with chronic upper limb pain. This trial is registered with ClinicalTrials.gov NCT01671267.

Purpose To examine rural status and social factors as predictors of self-rated health in community-dwelling adults in the United States. Methods This study uses multinomial logistic and cumulative logistic models to evaluate the associations of interest in the 2006 US Behavioral Risk Factor Surveillance System, a cross-sectional survey of 347,790 non-institutionalized adults. Findings Self-rated health was poorer among rural residents, compared to urban residents (OR = 1.77, 95% CI: 1.54, 1.90). However, underlying risk factors such as obesity, low income, and low educational attainment were found to vary by rural status and account for the observed increased risk (OR = 1.03, 95% CI: 0.94, 1.12). There was little evidence of effect modification by rural status, though the association between obesity and self-rated health was stronger among urban residents (OR = 2.50, 95% CI: 2.38, 2.64) than among rural residents (OR = 2.18, 95% CI: 2.03, 2.34). Conclusions Our findings suggest that differences in self-rated health by rural status were attributable to differential distributions of participant characteristics and not due to differential effects of those characteristics.

This study provides an empirical test of two mechanisms (social capital and exposure to air pollution) that are theorized to mediate the effect of neighborhood on health and contribute to racial disparities in health outcomes. To this end, we utilize the Social Capital Benchmark Study, a national survey of individuals nested within communities in the United States, to estimate how multiple dimensions of social capital and exposure to air pollution, explain racial disparities in self-rated health. Our main findings show that when controlling for individual-confounders, and nesting within communities, our indicator of cognitive bridging, generalized trust, decreases the gap in self-rated health between African Americans and Whites by 84%, and the gap between Hispanics and Whites by 54%. Our other indicator of cognitive social capital, cognitive linking as represented by engagement in politics, decreases the gap in health between Hispanics and Whites by 32%, but has little impact on African Americans. We also assessed whether the gap in health was explained by respondents' estimated exposure to toxicity-weighted air pollutants from large industrial facilities over the previous year. Our results show that accounting for exposure to these toxins has no effect on the racial gap in self-rated health in these data. This paper contributes to the neighborhood effects literature by examining the impact that estimated annual industrial air pollution, and multiple measures of social capital, have on explaining the racial gap in health in a sample of individuals nested within communities across the United States.

Introduction While seasonal influenza vaccination is recommended for individuals with asthma, uptake in this population is low. We examined how self-rated health impacts reasons for not being immunized against influenza in Canadian adults with asthma, focusing on those who have never been immunized. Methods We pooled four cycles of the Canadian Community Health Survey (cycles 3.1(2005), 2007/08, 2009/10 and 2011/12), grouping individuals by whether their reasons for not having been vaccinated were perceptual or technical. We used a multivariable logistic regression model, adjusted for confounders, to quantify the relationship between self-rated health and their reported reasons for not vaccinating. Results Among the 9,836 respondents, 84.4% cited perceptual barriers as a reason for not being vaccinated. After adjusting for socio-demographic characteristics and province of residence, we determined that reporting perceptual barriers was associated with self-rated health status, with the adjusted odds ratios ranging from 1.42 (95%CI: 0.97, 2.09) to 2.64 (95%CI: 1.74, 3.99) for fair and excellent health versus poor health, respectively. Each increase in self-rated health category was associated with greater odds of citing a perceptual rather than technical barrier as a reason for non-vaccination. Discussion Self-reported health influences people’s perception of the need for influenza vaccination. Viewing the results through the lens of the precaution adoption process model suggests that personalizing communication around both the risk of influenza and the effectiveness of the vaccine may improve uptake amongst adults with asthma.

We examined associations between adults’ use of a prominent rail-trail and their weight status and self-rated health. In 2014, a random-digit-dial survey of Greenville County, South Carolina, residents (n = 639) was used to collect data on trail use, height and weight, self-rated health, and demographics. Trail users were half as likely to be overweight or obese as trail nonusers (odds ratio [OR] = 0.56; 95% confidence interval [CI], 0.33–0.95). Similarly, trail users were significantly more likely to report high self-rated health than were trail nonusers (OR = 1.83; 95% CI, 1.13–2.97). Findings suggest that trail use is associated with healthier weight status and higher self-rated health and supports the development, maintenance, and promotion of trail resources. PMID:27978409

This study aimed to analyze the prevalence of negative self-rated health and associated factors in the quilombola community (descendants of escaped slaves) in Vitória da Conquista, Bahia State, Brazil. A household survey was conducted with 797 adults in 2011. Data on self-rated health, socioeconomic and demographic characteristics, lifestyle, social support, health status, and access to health services were obtained through questionnaires. Multivariate logistic regression analysis was performed, adjusted for sex and age. Prevalence of negative self-rated health was 12.5%. After statistical modeling, the following variables remained associated with self-rated health: skin color, schooling, adequate consumption of fruits and vegetables, chronic illness, physical limitations, and at least one medical visit in the previous 12 months. Self-rated health was associated with socioeconomic/demographic dimensions, lifestyle, social support, and health status.

Evidence of health inequities associated with sexual orientation has been gathered for industrialized countries. The situation for lesbians, gay males, and bisexuals (LGB) from middle- or low-income countries may be worse than those in industrialized nations. Here, we analyze the relationship of sexual orientation with self-rated health and cigarette and alcohol use among a representative sample of Mexican adolescents and youths between the ages of 12 and 29 years, in order to explore whether this association is mediated by discrimination and violence. Three dimensions of sexual orientation (affective attraction, sexual behavior, and identity) were assessed. The outcomes were self-rated health and cigarette and alcohol use. Compared to heterosexuals, LGB youths more frequently smoked >or=6 cigarettes per day, reported having experienced family violence, having crimes perpetrated against them, and having experienced violations of their rights. Among males, gays and bisexuals exhibited a higher risk of poor health than heterosexuals. Compared to heterosexual women, lesbians and bisexual women were more likely to consume alcohol. Many differences in self-rated health and substance use according to sexual orientation were explained by having experienced discrimination and violence. We concluded that lesbian and bisexual females have a higher prevalence of cigarette and alcohol use. It is necessary to develop policies and programs aimed at the reduction of substance abuse among LGB youths (focusing on females who engage in sexual contact with persons of the same gender) and to work against discrimination and violence experienced by LGB people, particularly against non-heterosexual males.

Chronic diseases, signals and symptoms of health problems and objective losses in functionality are seen as strongly related to low levels of life satisfaction in old age. Among seniors, self-rated health is associated with both quality of health and life satisfaction, but its relationships with objective health measures are controversial. This study aimed at identifying the influence of self-rated health as a mediator of the relationships between objectives indicators of physical and mental health and the elderly's life satisfaction. Self-reporting and physical performance measures were derived from the data basis of the FIBRA Study, which investigated frailty and associated variables in a cross-sectional sample of 2164 subjects aged 65 and above, randomly selected in seven Brazilian cities. A model considering satisfaction as a dependent variable, the number of diseases, frailty, cognitive status and depressive symptoms as predictors and self-rated health as a mediating variable was tested through path analysis. The model fit the data well and explained 19% of life satisfaction's variance. According to the bootstrapping method, indirect effects were significant for all trajectories, suggesting that self-rated health is a mediator variable between physical and mental health and elderlýs life satisfaction. In conclusion, adverse conditions of physical and mental health can influence the elderlýs life satisfaction, mostly when they determine a decrease in their levels of self-rated health.

Abstract The lack of social support in elderly populations incurs real societal costs and can lead to their poor health. The aim of this study is to investigate the self-rated health (SRH) and social support among older people as well as its associated factors. We conducted a cross-sectional study among 312 urban community-dwelling elderly aged 65 to 90 years in Tainan Taiwan and Fuzhou Fujian Province from March 2012 to October 2012. A Spearson correlation test, independent t test, a Pearson χ2 test, a linear regression analysis, and a multiple-level model were performed to analyze the results. The participants identified children as the most important source of objective and subjective support, followed by spouse and relatives. Tainan's elderly received more daily life assistance and emotional support, showed stronger awareness of the need to seek help, and maintained a higher frequency of social interactions compared with the elderly in Fuzhou. The mean objective support, subjective support, and support utilization scores as well as the overall social support among Tainan's elderly were significantly high compared with the scores among Fuzhou's elderly. Further, Tainan's elderly rated better SRH than Fuzhou's elderly. Correlation analysis showed that social support was significantly correlated with city, age, living conditions, marital status, and SRH. Multiple linear regression analysis, with social support as a dependent variable, retained the following independent predictors in the final regression model: city (4.792, 95% confidence interval [CI]: 3.068–6.516, P = 0.000), age (−0.805, 95% CI: −1.394 to −0.135, P = 0.013), marital status (−1.260, 95% CI: −1.891 to −0.629, P = 0.000), living conditions (4.069, 95% CI: 3.022–5.116, P = 0.000), and SRH −1.941, 95% CI: −3.194 to −0.688, P = 0.003). The multiple-level model showed that city would impact older people's social support (χ2 = 5.103, P < 0.001). Marital status (−2.133, 95
Background Self-Rated Health (SRH) correlates with risk of illness and death. But how are different questions of SRH to be interpreted? Does it matter whether one asks: “How would you assess your general state of health?”(General SRH) or “How would you assess your general state of health compared to persons of your own age?”(Comparative SRH)? Does the context in a questionnaire affect the answers? The aim of this paper is to examine the meaning of two questions on self-rated health, the statistical distribution of the answers, and whether the context of the question in a questionnaire affects the answers. Methods Statistical and semantic methodologies were used to analyse the answers of two different SRH questions in a cross-sectional survey, the MONICA-project of northern Sweden. Results The answers from 3504 persons were analysed. The statistical distributions of answers differed. The most common answer to the General SRH was “good”, while the most common answer to the Comparative SRH was “similar”. The semantic analysis showed that what is assessed in SRH is not health in a medical and lexical sense but fields of association connected to health, for example health behaviour, functional ability, youth, looks, way of life. The meaning and function of the two questions differ – mainly due to the comparing reference in Comparative SRH. The context in the questionnaire may have affected the statistics. Conclusions Health is primarily assessed in terms of its sense-relations (associations) and Comparative SRH and General SRH contain different information on SRH. Comparative SRH is semantically more distinct. The context of the questions in a questionnaire may affect the way self-rated health questions are answered. Comparative SRH should not be eliminated from use in questionnaires. Its usefulness in clinical encounters should be investigated. PMID:23046741

Objectives: Civic participation, that which directly influences important decisions in our personal lives, is considered necessary for developing a society. We hypothesized that civic participation might be related to self-rated health status. Methods: We constructed a multi-level analysis using data from the World Value Survey (44 countries, n=50 859). Results: People who participated in voting and voluntary social activities tended to report better subjective health than those who did not vote or participate in social activities, after controlling for socio-demographic factors at the individual level. A negative association with unconventional political activity and subjective health was found, but this effect disappeared in a subset analysis of only the 18 Organization for Economic Cooperation and Development (OECD) countries. Moreover, social participation and unconventional political participation had a statistically significant contextual association with subjective health status, but this relationship was not consistent throughout the analysis. In the analysis of the 44 countries, social participation was of borderline significance, while in the subset analysis of the OECD countries unconventional political participation was a stronger determinant of subjective health. The democratic index was a significant factor in determining self-rated health in both analyses, while public health expenditure was a significant factor in only the subset analysis. Conclusions: Despite the uncertainty of its mechanism, civic participation might be a significant determinant of the health status of a country. PMID:25652707

Background Research suggests that refugees are at an increased risk for poor health outcomes as compared to immigrants. However, prior studies have compared refugees and immigrants from different countries and have failed to isolate specific war-related factors. Objective To compare health outcomes and their determinants in refugees and immigrants from the same country of origin. Methods A cross-sectional study based on a convenient sample and on self-report participants were conducted at Southeast Michigan during the period September to December 2009. A validated survey was used to examine refugees (n = 75) and immigrants (n = 65) from Iraq. The survey covered socioeconomics, lifestyle, violence exposure, self-rated health, and number of medical conditions (high blood pressure, fatigue, and backache, shortness of breath, gastrointestinal disorders, skin problems, and musculoskeletal problems). Group differences and predictors of health outcomes were assessed. Results Refugees reported significantly more violence exposure than immigrants (p < 0.001). There were no significant differences in self-rated health or medical disorders between groups; however, violence exposure was the main predictor of health outcomes in refugees, whereas age was the main predictor in immigrants. Other predictors also varied by migratory group. Conclusion Even though migration status did not directly influence health outcomes, results suggest that factors associated with migration status, e.g., violence exposure and age, do impact health. Future studies need to more carefully define and control for country-specific variables. PMID:26644795

There are concerns about the meaning of SRH and the factors individuals consider. To illustrate how SRH is contextualized, we examine how the obesity-SRH association varies across age, periods, and cohorts. We decompose SRH into subjective and objective components and used a mechanism-based APC model approach with four decades (1970s-2000s) and five birth cohorts of NHANES data (N=26,184). Obese adults rate their health more negatively than non-obese when using overall SRH with little variation by age, period, or cohort. However, when we decomposed SRH into objective and subjective components, the obesity gap widened with increasing age in objective SRH, but narrowed in subjective SRH. Additionally, the gap narrowed for more recently-born cohorts for objective SRH, but widened for subjective SRH. The results provide indirect evidence that the relationship between obesity and SRH is socially patterned according to exposure to information about obesity and the availability of resources to manage it.

Objectives: Despite the well-established association between self-rated health and mortality, research findings have been inconsistent regarding how men and women differ on this link. Using a national sample in the United States, this study compared American male and female older adults for the predictive role of baseline self-rated health on the short-term risk of mortality. Methods: This longitudinal study followed 1500 older adults (573 men (38.2%) and 927 women (61.8%)) aged 66 years or older for 3 years from 2001 to 2004. The main predictor of interest was self-rated health, which was measured using a single item in 2001. The outcome was the risk of all-cause mortality during the 3-year follow-up period. Demographic factors (race and age), socio-economic factors (education and marital status), and health behaviors (smoking and drinking) were covariates. Gender was the focal moderator. We ran logistic regression models in the pooled sample and also stratified by gender, with self-rated health treated as either nominal variables, poor compared to other levels (i.e. fair, good, or excellent) or excellent compared to other levels (i.e. good, fair, or poor), or an ordinal variable. Results: In the pooled sample, baseline self-rated health predicted mortality risk, regardless of how the variable was treated. We found a significant interaction between gender and poor self-rated health, indicating a stronger effect of poor self-rated health on mortality risk for men compared to women. Gender did not interact with excellent self-rated health on mortality. Conclusion: Perceived poor self-rated health better reflects risk of mortality over a short period of time for older men compared to older women. Clinicians may need to take poor self-rated health of older men very seriously. Future research should test whether the differential predictive validity of self-rated health based on gender is due to a different meaning of poor self-rated health for older men and women

This study examines whether health inequalities exist between lone and cohabiting mothers across Europe, and how these may differ by welfare regime. Data from the European Social Survey were used to compare self-rated general health, limiting long-standing illness and depressive feelings by means of a multi-level logistic regression. The 27 countries included in the analyses are classified into six welfare regimes (Anglo-Saxon, Bismarckian, Southern, Nordic, Central East Europe (CEE) (new EU) and CEE (non-EU). Lone motherhood is defined as mothers not cohabiting with a partner, regardless of their legal marital status. The results indicate that lone mothers are more at risk of poor health than cohabiting mothers. This is most pronounced in the Anglo-Saxon regime for self-rated general health and limiting long-standing illness, while for depressive feelings it is most pronounced in the Bismarckian welfare regime. While the risk difference is smallest in the CEE regimes, both lone and cohabiting mothers also reported the highest levels of poor health compared with the other regimes. The results also show that a vulnerable socioeconomic position is associated with ill-health in lone mothers and that welfare regimes differ in the degree to which they moderate this association.

We examined the relationship between self-rated health and use of parks and recreation program participation by using logistic regression to analyze data from representative national surveys conducted in 1991 and 2015. Neither park use nor program participation were significantly related to self-rated health in 1991; however, both were significantly related in 2015. The growing relationship between use of parks and recreation programs and self-rated health during this period is likely the result of broad national health promotion efforts and provides support for funding of capital and operational expenses for park and recreation services.

Optimism has been shown to be important in maintaining wellbeing into old age, but little is known about the sources of variation in optimism and its links to mental and somatic health. Optimism, mental, and self-rated health were measured in 3,053 twin individuals (501 MZF, 153 MZM, 274 DZF, 77 DZM, and 242 DZ opposite-sex twin pairs and 561 single twins) over 50 years using the life orientation test, the General Health Questionnaire and a single-item question for self-rated health. Additive genetic factors explained 36, 34, and 46% of the variation in optimism, mental, and self-rated health, respectively, with the remainder being due to non-shared environmental influences. Genetic influences accounted for most of the covariance between the variables (14-20% of the genetic variance) indicating that in older adults genes predisposing to high optimism also predispose to good mental health and self-rated health.

Purpose/Objectives To describe factors related to diagnosis, identity disclosure, and social support among lesbian, gay, bisexual, and transgender (LGBT) patients with cancer, and to explore associations between these factors and self-rated health. Design Cross-sectional self-report survey design using descriptive and exploratory multivariate statistical approaches. Setting Online, Internet-based. Sample 291 LGBT patients (89% Caucasian; 50% gay, 36% lesbian, 7% bisexual, 3% transgender) with mixed cancers. Methods Participants completed a researcher-designed online survey assessing experiences of cancer diagnosis among LGBT patients at a single time point. Main Research Variables Demographics, which provider(s) delivered the patients’ cancer diagnoses, to whom patients had disclosed their LGBT identity, how they disclosed, who was on their social support team at the time of diagnosis, and current self-rated health. Findings 79% of participants reported disclosing their identities to more than one cancer care provider. Participants most commonly introduced the topic of LGBT identity themselves, sometimes as a way to correct heterosexual assumptions (34%). Friends were the most common members of LGBT patients’ support teams (79%). Four disclosure and support factors were consistently associated with better self-rated health. Conclusions Disclosure of LGBT identity is a common experience in the context of cancer care, and disclosure and support factors are associated with better self-reported health among LGBT patients. Implications for Nursing Creating safe environments for LGBT patients to disclose could improve cancer care delivery to this underserved population. Nurses and other providers should acknowledge and include diverse support team members in LGBT patients’ care. PMID:25542320

Despite accumulating evidence of associations between social capital and health in public health research, a criticism of the field has been that researchers have exclusively focused on concepts of social cohesion to the exclusion of individual-level approaches. In the present study, we evaluated the association between social capital measured by the Resource Generator (an individual-level assessment of access to social capital) and self-rated health among Japanese population in a cross-sectional study. A postal survey of 4000 randomly selected residents in Okayama City (western Japan) was conducted in February 2009. We divided the overall scores from the Resource Generator Japan scale into quartiles. Odds ratios (ORs) and 95% confidence intervals (CIs) for self-rated health were calculated separately by sex. Individuals with the highest quartile of scores had significantly lower odds of poor health compared to the lowest group after covariate adjustment among both men and women (men; OR: 0.45, 95% CI: 0.24-0.86, women; OR: 0.44, 95% CI: 0.25-0.79, respectively) and there were also significant dose-response relationships. In the sub-domains of Resource Generator Japan scale, a differential pattern was observed by sex. Women showed a clear dose-response relationship with health across all four sub-scales (domestic resources, expert advice, personal skills, and problem solving resources). In contrast, only the domain of expert advice exhibited a strong association with men's health. Among both men and women individual-level social capital measured by the Resource Generator was related to reduced odds of poor health even after taking into account individual confounders. Although we cannot exclude reverse causation due to the cross-sectional design, our study adds to the accumulating evidence of the potential utility of the Resource Generator for evaluating the relationship between individual-level access to social capital and health.

The purpose of the study is (1) to compare the effects of factors on self-rated health (SRH) among older non-Hispanic Whites (NHW), Hispanic, and Asian Californians and (2) to provide estimated influence size of each factor on SRH. This study analyzed secondary data drawn from the 2005 California Health Interview Survey. Binary logit regressions were used to analyze data with the Jackknife replication sampling weights. Significant differences were found in SRH among the three groups. Hispanics and Asians reported poorer health than NHW. Socioeconomic status, acculturation, and health access significantly accounted for an association between ethnicity and SRH. However, the magnitudes of their effects on SRH varied across the groups and by the factors examined. This study discusses and concludes with some recommendations on the opportunities presented by the Affordable Care Act and Healthy People 2020.

The effects of exposure to terror on physical health were investigated by relating objective exposure to terror and fear of terror to self-rated health (SRH), a proxy measure of health status. Our respondents were apparently healthy (N=4,877, 38% women) adults who completed self-report questionnaires. Objective exposure was assessed by the number of terrorist attacks and their casualties in a respondent's urban area prior to her/his completion of the questionnaire. Using several alternative assessments, objective exposure to terror did not predict SRH for both the genders. As hypothesized, fear of terror negatively predicted SRH for both females and males (beta=-0.04, -0.05, respectively). The effects of subjective and objective exposure were not found to be more pronounced among women relative to men, thus disconfirming our hypotheses in this regard. Our findings suggest that living under continuous fear of terror may adversely influence physical health irrespective of objective exposure.

Introduction: Self-rated health (SRH) has beeen considered an important marker of quality of life and an independent predictor of mortality in older adults. Objective: To determine the prevalence of poor SRH and identify risk factors associated with poor SRH among older adults residing in the Commune 18 of the city of Cali, Colombia, in 2009. Methods: A population-based cross-sectional study with a single-stage cluster sampling design. Sample included 314 persons aged 60 and older. The dependent variable, SRH was dichotomized into good (excellent, very good, good) and poor (fair, poor). Independent variables were sociodemographic, biological, mental, functional and geriatric syndromes. Logistic regression was used for multivariate statistical modeling. Results: Overall, 40.1% reported poor SRH (women 42.9%, men 35.0%). Factors independently associated with poor SRH were diabetes mellitus, depression, fear of falling and frailty syndrome (frail and pre-frail vs. non-frail). Widowed men reported poorer health than married men while other marital status (single/separated/divorced) was associated with better self-rated health in women.

The current study examined whether dispositional gratitude predicts physical health among adults, and if so, whether this relationship occurs because grateful individuals lead healthier lives, either psychologically or physically. Specifically, we examined whether psychological health, healthy activities, and willingness to seek help for health concerns mediated the link between gratitude and self-reported physical health, as well as if these mediational pathways are moderated by age, in a broad sample of Swiss adults (N = 962, M(age) = 52 years, age range: 19 to 84). Dispositional gratitude correlated positively with self-reported physical health, and this link was mediated by psychological health, healthy activities, and willingness to seek help for health concerns. However, the indirect effects for psychological health and healthy activities were stronger for older than younger adults. In other words, the mechanisms explaining why gratitude predicts health appear to differ across adulthood.

Stress in the social environment can affect individual health. Election of the first Black President of the United States provides an opportunity to assess how a positive change in the macro-political climate impacts the health of Americans. Past research suggests that race-related political events influence the health of non-dominant racial groups. Yet many questions remain, including the types of events that affect health, the timing and durability of health effects, and whether effects are similar for Blacks and Hispanics in the United States. The present study uses data from the Ohio Family Health Survey, which was in the field from August 6, 2008 until January 24, 2009, to assess whether immediate changes in average self-rated health occurred after key events in the election of President Barack Obama. We find better average health ratings among Blacks and Hispanics immediately following Obama's nomination by the Democratic Party. Similar effects did not occur after the election or inauguration, and Whites showed no effect of any of the events. We discuss the implications of these findings in terms of the theoretical links between macro-level social conditions, race/ethnicity, and health.

Chewing xylitol gum provides oral health benefits including inhibiting Streptococcus mutans plaque. It is thought to be especially effective in conditions where it is difficult to perform daily oral cleaning. Our study aim was to determine the effects of chewing xylitol gum on self-rated and objective oral health status under a condition interfering with oral hygiene maintenance. A randomized controlled intervention trial was conducted on 55 healthy ≥ 20-year-old men recruited from the Japan Ground Self Defense Force who were undergoing field training. Participants were randomly assigned to a test group (chewing gum; n = 27) or a control group (no gum; n = 28) and the researchers were blinded to the group assignments. The Visual Analog Scale (VAS) scores of oral conditions subjectively evaluated oral health, and the stimulated salivary bacteria quantity objectively evaluated oral health 1 day before field training (baseline) and 4 days after the beginning of field training (follow-up). VAS scores of all three oral conditions significantly increased in the control group (malodor: p < 0.001; discomfort: p < 0.001; dryness: p < 0.001), but only two VAS scores increased in the test group (malodor: p = 0.021; discomfort: p = 0.002). The number of salivary total bacteria significantly increased in the control group (p < 0.01), while no significant change was observed in the test group (p = 0.668). Chewing xylitol gum positively affects self-rated and objective oral health status by controlling oral hygiene under conditions that interfere with oral hygiene maintenance.

This comparative, cross-sectional study analyzed negative self-rated health in elderly people, according to sociodemographic and health variables, use of public or private health services, functional performance, frailty and depressive symptoms. The participants lived in Belém (n = 571) and Campinas (n = 676), cities with different socioeconomic conditions, and the research formed part of a multicentric study on frailty (Fibra Study, Unicamp). Multivariate regression analysis showed that in both cities, negative self-rated health was associated with low education, three or more chronic diseases and sight deficiencies. In Belem, additional observations included associations with fatigue, three or more signs and symptoms and use of public health services; in Campinas, negative self-rated health was also associated with depressive symptoms. The associations suggest that poor health in old age is the result of an accumulation of deficits for lack of socioeconomic resources throughout life and that deficits are not sufficiently compensated for health services in old age.
Social scientists have long demonstrated that socioeconomic resources benefit health. More recently, scholars have begun to examine the potential stratification in the health returns different groups receive for a given resource. Motivated by fundamental cause theory, this paper examines homeownership as a salient health resource with potentially stratified benefits. Homeowners have significantly greater housing quality, wealth, neighborhood quality and integration, and physical and mental health than renters. However, there are compelling theoretical reasons to expect the health advantage of homeownership to be unequally distributed across racial and ethnic groups. Regression analyses of 71,874 household heads in the United States from the 2012 March Current Population Survey initially suggest all homeowners experience a significant health advantage. Further examination finds robust evidence for a homeowner health advantage among Whites, on par with the difference between the married and divorced. The advantage among minority households is considerably smaller, and not significant among Latinos or Asians. Conditioning on a broad array of observable characteristics, White homeowners emerge as exceptionally healthy compared to White renters and all minority groups. This leads to the unexpected finding that racial/ethnic differences in health are concentrated among homeowners. The findings demonstrate the interactive nature of racial/ethnic stratification in health through both access to and returns from socioeconomic resources.

We systematically reviewed studies to identify the association between acculturation and self-rated health (SRH) and the impact of nativity and language use in Asian and Hispanic adult immigrants. Six electronic databases were searched. Data on nativity and limited English proficiency (LEP) was extracted and analyzed. Nine studies met review criteria. A positive association between acculturation and fair/poor SRH among Asians and Hispanics was found. For both Asians and Hispanics, six out of eight studies showed nativity and all three studies reporting LEP were associated with worse SRH compared to whites. Nativity and LEP were found to be risk factors for reporting worse SRH in Hispanics compared to Asians. The degree of association between nativity and LEP and worse SRH was found to vary by Asian and Hispanic subgroup. Further studies are needed to accurately assess the health status of these populations, which will be essential to eliminating disparities.

The association between many psychosocial factors and risk of suicide was examined. A cohort was conducted over 14 years of follow up among the general population (15,597 people) in Japan. A baseline survey of psychosocial characteristics was conducted by self-administrated questionnaire. The relative risks of occasional emotional stress, difficulty maintaining sleep, and reporting unhealthy as their self-rated health are 3.2 (95% CI: 1.3, 7.6), 2.4 (95% CI: 1.3, 4.3) and 2.6 (95% CI: 1.1, 6.2), respectively. The importance of these observations lie in its potential for improving physician and public awareness of psychosocial factors as an early indication of mental health morbidity.

Objectives. The purpose of this study is to examine the relationship between religiously based beliefs about suffering and health among older Mexicans. Methods. A nationwide survey of older Mexican Americans was conducted (N = 1,005). Questions were administered to assess beliefs about finding positive outcomes in suffering, the benefits of suffering in silence, other dimensions of religion, and health. Results. The findings suggest that older Mexican Americans who use their faith to find something positive in the face of suffering tend to rate their health more favorably. In contrast, older Mexican Americans who believe that it is important to suffer in silence tend to rate their health less favorably. Discussion. Moving beyond measures of church attendance to explore culturally relevant beliefs about suffering provides important insight into the relationship between religion and health among older Mexican Americans.

BACKGROUND This study examined gender differences in the impact of warfare exposure on self-reported physical health. METHODS Data are from the 2010 National Survey of Veterans, a nationally representative survey of veterans from multiple eras of service. Regression analyses assessed gender differences in the association between warfare exposure (deployment to a war zone, exposure to casualties) and health status and functional impairment, adjusting for sociodemographics. FINDINGS Women reported better health status but greater functional impairment than men. In men, those who experienced casualties only or both casualties and deployment to a war zone had worse health compared to those who experienced neither stressor or deployment to a war zone only. In women, those who experienced casualties only or both stressors reported worse health than those who experienced war zone only, who did not differ from the unexposed. No association was found between warfare exposure and functional impairment in women, but in men, those who experienced exposure to casualties or both stressors had greater odds of functional impairment compared to those who experienced war zone only or neither stressor. CONCLUSIONS Exposure to casualties may be more predictive of health than deployment to a war zone, especially for men. We did not find a stronger association between warfare exposure and health for women than men. Given that the expansion of women's military roles has allowed them to serve in direct combat, their degree and scope of warfare exposure is likely to increase in the future. PMID:25442366

Policy Points Despite beliefs that baby boomers are healthier than previous generations, we found no evidence that the health of baby boomers is substantially different from that of the previous or succeeding cohorts. The effects of increased education, higher income, and lower smoking rates on improving self-rated health were nearly counterbalanced by the adverse effect of increasing body mass index (BMI). Assumptions that baby boomers will require less health care as they age because of better education, more prosperity, and less propensity to smoke may not be realized because of increases in obesity. Context Baby boomers are commonly believed to be healthier than the previous generation. Using self-rated health (SRH) as an indicator of health status, this study examines the effects of age, period, and birth cohort on the trajectory of health across 4 generations: World War II (born between 1935 and 1944), older baby boomers (born between 1945 and 1954), younger baby boomers (born between 1955 and 1964), and Generation X (born between 1965 and 1974). Methods We analyzed Canada’s longitudinal National Population Health Survey 1994-2010 (n = 8,570 at baseline), using multilevel growth models to estimate the age trajectory of SRH by cohort, accounting for period and incorporating the influence of changes in education, household income, smoking status, and body mass index (BMI) on SRH over time. Findings SRH worsened with increasing age in all cohorts. Cohort differences in SRH were modest (p = 0.034), but there was a significant period effect (p = 0.002). We found marked cohort effects for increasing education, income, and BMI, and decreasing smoking from the youngest to the oldest cohorts, which were much reduced (education and smoking) or removed (income and BMI) once period was taken into account. At the population level, multivariable analysis showed the benefits of increasing education and income and declines in smoking on the trajectory of improving SRH were

This paper uses data from the U.S. National Health Interview Surveys (N = 1,513,097) to describe and explain temporal patterns in black-white health disparities with models that simultaneously consider the unique effects of age, period, and cohort. First, we employ cross-classified random effects age–period–cohort (APC) models to document black-white disparities in self-rated health across temporal dimensions. Second, we use decomposition techniques to shed light on the extent to which socio-economic shifts in cohort composition explain the age and period adjusted racial health disparities across successive birth cohorts. Third, we examine the extent to which exogenous conditions at the time of birth help explain the racial disparities across successive cohorts. Results show that black-white disparities are wider among the pre-1935 cohorts for women, falling thereafter; disparities for men exhibit a similar pattern but exhibit narrowing among cohorts born earlier in the century. Differences in socioeconomic composition consistently contribute to racial health disparities across cohorts; notably, marital status differences by race emerge as an increasingly important explanatory factor in more recent cohorts for women whereas employment differences by race emerge as increasingly salient in more recent cohorts for men. Finally, our cohort characteristics models suggest that cohort economic conditions at the time of birth (percent large family, farm or Southern birth) help explain racial disparities in health for both men and women.

This article examines the association between material hardships and self-rated mental health (SRMH) among older black Americans and determines whether the effect varies by race and ethnicity. Using data from the National Survey of American Life, multiple logistic regression models were specified on a sample of older white Americans (n = 289), African Americans (n = 1,135), and black Caribbean Americans (n = 377). Material hardship was measured as an index of seven items that occurred within the past year. Material hardship (odds ratio = 0.48; 95 percent confidence interval = 0.29-0.79) was associated with SRMH for both groups. None of the interactions were significant. The study concludes that material hardship may contribute to poorer SRMH among older African Americans and black Caribbean Americans. Future studies should examine these associations by using longitudinal designs, which may be better designed to confirm these results.

Objective The aim of this study was to explore the validity of self-rated health across different populations of older adults, when compared to the Short Physical Performance Battery. Design Cross-sectional analysis of the International Mobility in Aging Study. Setting Five locations: Saint-Hyacinthe and Kingston (Canada), Tirana (Albania), Manizales (Colombia), and Natal (Brazil). Participants Older adults between 65 and 74 years old (n = 1,995). Methods The Short Physical Performance Battery (SPPB) was used to measure physical performance. Self-rated health was assessed with one single five-point question. Linear trends between SPPB scores and self-rated health were tested separately for men and women at each of the five international study sites. Poor physical performance (independent variable) (SPPB less than 8) was used in logistic regression models of self-rated health (dependent variable), adjusting for potential covariates. All analyses were stratified by gender and site of origin. Results A significant linear association was found between the mean scores of the Short Physical Performance Battery and ordinal categories of self-rated health across research sites and gender groups. After extensive control for objective physical and mental health indicators and socio-demographic variables, these graded associations became non-significant in some research sites. Conclusion These findings further confirm the validity of SRH as a measure of overall health status in older adults. PMID:27089219
This thesis is centered on self-rated health (SRH) as an outcome measure, as a predictor, and as a marker. The thesis uses primary data from the WHO Study on global AGEing and adult health (SAGE) implemented in India in 2007. The structural equation modeling approach is employed to understand the pathways through which the social environment, disability, disease, and sociodemographic characteristics influence SRH among older adults aged 50 years and above. Cox proportional hazard model is used to explore the role of SRH as a predictor for mortality and the role of disability in modifying this effect. The hierarchical ordered probit modeling approach, which combines information from anchoring vignettes with SRH, was used to address the long overlooked methodological concern of interpersonal incomparability. Finally, multilevel model-based small area estimation techniques were used to demonstrate the use of large national surveys and census information to derive precise SRH prevalence estimates at the district and sub-district level. The thesis advocates the use of such a simple measure to identify vulnerable communities for targeted health interventions, to plan and prioritize resource allocation, and to evaluate health interventions in resource-scarce settings. The thesis provides the basis and impetus to generate and integrate similar and harmonized adult health and aging data platforms within demographic surveillance systems in different regions of India and elsewhere.

Both clinical diagnoses and self-rated measures of mental illness are associated with a variety of outcomes, including physical well-being, health utilization, and expenditure. However, much of current literature primarily utilizes clinically diagnosed data.This cross-sectional study explores the impact of mental illness and health care expenditure using 2 self-rated measures: self-rated measured of perceived mental health status (SRMH) and Kessler Screening Scale for Psychological Distress (K6).Data from the 2011 Medical Expenditure Panel Survey Household Component, a nationally representative sample of noninstitutionalized individuals (n = 18,295), were analyzed using bivariate χ tests and a 2-part model (logistics regression and generalized linear model regression for the first and second stages, respectively).Although predictive of any health expenditure, SRMH alone was not highly predictive of the dollar value of that health expenditure conditional on any spending. By comparison, the K6 measure was significantly and positively associated with the probability of any health expenditure as well as the dollar value of that spending. Taken together, both the K6 and SRMH measures suggest a positive relationship between poor mental health and the probability of any health expenditure and total expenditure conditional on any spending, even when adjusting for other confounding factors such as race/ethnicity, sex, age, educational attainment, insurance status, and some regional characteristics.Our results suggest that psychological distress and SRMH may represent potential pathways linking poor mental health to increased health care expenditure. Further research exploring the nuances of these relationships may aid researchers, practitioners, and policy makers in addressing issues of inflated health care expenditure in populations at risk for poor mental health.

Objectives Although there is evidence that socioeconomic conditions in adulthood are associated with worse self-rated health, the putative effect of early adverse life circumstances on adult self-rated health is not consistent. Besides, little is known on this subject in the context of middle-income countries. We aimed to investigate the association between indicators of socioeconomic position in early life and self-rated health in adulthood, taking into account the influence of current socioeconomic position. Design Cross-sectional. Participants 3339 civil servants (44.5% male) working at a public university in Rio de Janeiro, Brazil, participants of the Pró-Saúde cohort study. Measurements Through a lifecourse approach, we evaluated if seven indicators of participants’ socioeconomic position earlier in life were associated with worse self-rated health in adulthood. Ordinal logistic regression analysis with a proportional odds model was used. Results After adjusting for socioeconomic position in adulthood (education and income), the indicators of early socioeconomic position associated with poor self-rated health were as follows: not eating at home due to lack of money at the age of 12 (OR=1.29 95% CI 1.06 to 1.57) and having lived in a small city or rural area at the age of 12 (OR=1.51 95% CI 1.21 to 1.89). Conclusions Self-rated health was associated with two indicators of remarkable experiences of poverty in early life, even when socioeconomic conditions improved throughout life. Our findings have shown a long-term impact of extreme socioeconomic hardship during childhood and/or adolescence on the development of social inequalities in health. In terms of implications for public health, our work emphasises that health policies, usually focused on adult lifestyle interventions, should be complemented by initiatives aimed at reducing socioeconomic inequalities during the earliest stages of development, such as childhood and adolescence.

Objective Self-rated health is a powerful predictor of long-term health and mortality, hence the importance of a better understanding of its biological determinants. Previous studies have shown that low-grade inflammation is associated with poor self-rated health in clinical and healthy populations, but the evidence is sparse in men and completely lacking for men in late adolescence. The aim of this study was to investigate the association between low-grade inflammation and self-rated health among conscripts. It was hypothesised that high levels of inflammatory factors would be associated with poor self-rated health. Design Data from 49 321 men (18–21 years) conscripted for military service in 1969 and 1970 were used. Inflammation had been measured through erythrocyte sedimentation rate (ESR). Self-rated health had been assessed on a five-point scale, and was dichotomised into Good (‘Very good’/‘Good’/‘Fair’) versus Poor (‘Poor’/‘Very poor’). Data from 43 110 conscripts with normal levels of ESR, and who reported self-rated health remained after exclusion of those with ESR <1 and >11 mm/h. Associations were calculated using logistic regression analyses. Adjustments were made for body mass index, socioeconomic position, inflammatory disease, emotion regulation, smoking, risky use of alcohol and physical activity. Results High levels of ESR were associated with higher odds for poor self-rated health (OR: 1.077 for each unit mm/h increase in ESR, 95% CI 1.049 to 1.105). Conclusions The present study shows for the first time a significant association between a marker of inflammation and self-rated health in late adolescent men, adding to evidence of an association between low-grade inflammation and subjective health perception also in men, as previously demonstrated in women. Further support for inflammation as part of a general psychobiological process that underpins subjective health perception is hereby provided. PMID:27113233

Purpose of the Study: With increasing longevity in industrialized populations, there is growing interest in what defines “successful aging” (SA). Various SA measures have been proposed but no consensus has been reached and many have been criticized for not representing the views and priorities of older people. We consider whether the Rowe–Kahn SA model captures older individual’s perceptions of their own health and aging. Methods: Using two cohorts of 886 and 483 men and women from the West of Scotland Twenty-07 Study, aged around 57 and 76, respectively, we explored associations between Rowe–Kahn SA dimensions (absence of disease/disability; good physical/cognitive functioning; good interpersonal/productive social engagement) and four aspects of self-rated health and satisfaction (current general health; health for age; satisfaction with health; satisfaction with life). Results: Respondents’ self-rated health and satisfaction was generally good but few had all six Rowe–Kahn dimensions positive, the conventional definition of SA. All individual positive SA dimensions were associated with better self-rated health and satisfaction. This was consistent across age, gender, manual/nonmanual occupations, and personality. The prevalence of good self-rated health and satisfaction increased with increasing numbers of positive SA dimensions. Implications: The Rowe–Kahn model provides a functional definition of SA. Future work on ageing should include all Rowe–Kahn dimensions and consider SA as a continuum. PMID:26970606

Cancer self-efficacy (CSE) and spiritual well-being (SWB) have been associated with better self-rated health (SRH) among breast cancer survivors (BCS), but have not been well studied among Latina BCS (LBCS). Multivariate logistic regression analyses of secondary data from a cross-sectional population-based telephone survey of 330 LBCS explored relationships of language acculturation, CSE, and SWB subdomains of inner peace and faith with SRH. English proficiency was associated with SRH, independent of other covariates (OR=2.26, 95% CI 1.15, 4.45). Cancer self-efficacy attenuated this effect and was positively associated with SRH (OR=2.24, 95% CI 1.22, 4.10). Adding inner peace (a SWB subscale) attenuated the association of CSE and SRH (OR=1.67, 95% CI 0.88, 3.18). Inner peace remained associated with SRH (OR= 2.44, 95% CI 1.30, 4.56), controlling for covariates. Findings support the importance of a sense of inner peace and control over breast cancer to LBCS' perceived health. PMID:25418229

Although the relation between self-rated health (SRH) and mortality is widely known, most of the studies have relied in baseline measurements unheeding the dynamics of the phenomenon. Our aim was to analyze how SRH both as a constant and as a time-dependent covariate predicts mortality in older men and women and to compare these different approaches. Subjects consisted of 110 male and 208 female (n=318) residents in the city of Jyväskylä, central Finland, aged 75 years at the baseline in 1989. The follow-up data was gathered in 1994 and mortality was followed for 10 years. Results showed that poor SRH was strongly associated with higher mortality risk in women in all models. In men, the association was found only in time-dependent and 5 year follow-up models and these associations were explained by baseline health status. To conclude, our analyses showed that there are gender differences in association between SRH and mortality and that the use of time-dependent covariate in a Cox regression model enables advantage to be taken of all the information in a longitudinal study design.

Objective Due to the growing proportion of older employees in the work force in several countries, the importance of age in the association between work and health is becoming increasingly relevant. Few studies have investigated whether age modifies the association of physical work demands with health. We hypothesized that the association of demanding body postures with deteriorated self-rated health (SRH) is stronger among older employees than among younger employees. Method We analyzed three 5-year cohorts in the Danish Work Environment Cohort Study comprising 8318 observations from 5204 employees (follow-up participation rate 83%) with good baseline SRH. Physical work demands were assessed as demanding body postures. Age was divided into tertiles; young (18-32 years), middle-aged (33-43 years) and old (44-59 among men and 44-54 years among women). Poor SRH ("fairly good", "poor", and "very poor") was measured with a single item. Log binomial regressions were stratified by gender. Effect modification (ie, interaction) was defined as deviation from additivity and examined by calculating the relative excess risk due to interaction (RERI). The reference group was employees aged 18-32 years with low physical exposure. Results When predicting deterioration of SRH, an interaction between demanding body postures and age was found among men [RERI: 0.75, 95% confidence interval (95% CI) 0.16-1.34, regarding the age group 44-59 years] and among women (RERI: 0.84, 95% CI 0.19-1.34, for the age group 33-43 years; and 1.17, 95% CI 0.42-1.93, for the age group 44-54 years). Conclusion The study findings suggest that demanding body postures have a stronger impact on health among older compared to younger employees.

The predictive effects of age and self-rated health (SRH) on all-cause mortality are known to differ across race and ethnic groups. African American adults have higher mortality rates than Whites at younger ages, but this mortality disparity diminishes with advancing age and may "crossover" at about 75-80 years of age, when African Americans may show lower mortality rates. This pattern of findings reflects a lower overall association between age and mortality for African Americans than for Whites, and health-related mechanisms are typically cited as the reason for this age-based crossover mortality effect. However, a lower association between poor SRH and mortality has also been found for African Americans than for Whites, and it is not known if the reduced age and SRH associations with mortality for African Americans reflect independent or overlapping mechanisms. This study examined these two mortality predictors simultaneously in a large epidemiological study of 12,181 African Americans and 17,436 Whites. Participants were 45 or more years of age when they enrolled in the national REasons for Geographic and Racial Differences in Stroke (REGARDS) study between 2003 and 2007. Consistent with previous studies, African Americans had poorer SRH than Whites even after adjusting for demographic and health history covariates. Survival analysis models indicated statistically significant and independent race*age, race*SRH, and age*SRH interaction effects on all-cause mortality over an average 9-year follow-up period. Advanced age and poorer SRH were both weaker mortality risk factors for African Americans than for Whites. These two effects were distinct and presumably tapped different causal mechanisms. This calls into question the health-related explanation for the age-based mortality crossover effect and suggests that other mechanisms, including behavioral, social, and cultural factors, should be considered in efforts to better understand the age-based mortality

Objective. To explore racial differences in self-rated health (SRH) and its relationship to activities of daily living (ADLs) and mobility limitations among stroke survivors. Method. Data from 580 Black and White participants of the North Carolina Established Populations for Epidemiologic Studies of the Elderly (EPESE) were used to assess relationships between SRH, ADLs, and mobility variables. Fisher's exact tests, t tests, and logistic regression with backward selection (p < .20) were used. Results. No racial difference in SRH was found. SRH was significant in predicting ADL status among Whites only (OR = 0.23; CI = 0.08-0.69; p < .01). Participants older than 75 years had a greater likelihood of being in the lowest functioning ADL categories (OR = 2.31; CI = 1.48-3.60; p < .01). Discussion. Though no racial differences in SRH were found, the relationship between SRH, ADLs, and mobility status was moderated by race. SRH was predictive of limitations in Whites only. Observed differences suggest SRH construct may differ by race.

The objective of this study was to examine the prevalence and consequences of coexisting vision and cognitive impairments in an Asian population. Data were collected from 4508 community-dwelling Singaporeans aged 60 years and older. Cognition was assessed by the Short Portable Mental Status Questionnaire whereas vision, disability, and self-rated health (SRH) were determined by self-report. Vision impairment was present in 902 (18.5%) participants and cognitive impairment in 835 (13.6%), with 232 (3.5%) participants experiencing both impairments. Persons with the comorbidity experienced higher odds of disability than persons with either single impairment. The association of vision impairment with SRH was stronger among women (odds ratio [OR] = 6.79, 95% confidence interval [CI] = 4.64-9.92) than among men (OR = 1.71, 95% CI = 1.21-2.41). Concurrent cognitive and vision impairment is prevalent in older Singaporeans and is associated with high rates of disability. Gender differences in vision-dependent roles may affect the patient-perceived impact of this comorbidity.

Symmetric, aligned and luminous smiles are usually classified as 'beautiful' and aesthetic. However, smile perception is not strictly governed by standardised rules. Personal traits may influence the perception of non-ideal smiles. We aimed to determine the influence of personality traits in self-rated oral health and satisfaction and in the aesthetic preference for different strategically flawed smiles shown in photographs. Smiles with dark teeth, with uneven teeth, with lip asymmetry and dental asymmetry were ordered from 1 to 4 as a function of the degree of beauty by 548 participants, of which 50·7% were females with a mean age of 41·5 ± 17·6 years (range: 16-89 years). Self-assessment and oral satisfaction were recorded on a Likert scale. Personality was measured by means of the Big Five Inventory (extraversion, agreeableness, conscientiousness, neuroticism and openness), and the Life Orientation Test was used to measure optimism and pessimism. Of the four photographs with imperfect smiles, dental asymmetry was the most highly assessed in 63% of the sample, and the worst was lip asymmetry, in 43·7% of the sample. Some personality traits (above all conscientiousness and openness) were significantly correlated with the position assigned to the photographs with dental and lip asymmetry or with misaligned teeth. The extraversion, agreeableness and openness traits were correlated with the self-perceptions of oral health and aesthetics of the participants. Dental asymmetry seems to be better tolerated than lip asymmetry. Personality traits are weakly but significantly correlated with the aesthetic preference and oral health values, conscientiousness and openness being the most relevant domains in this sense.

The evidence base for women's oral health is emerging from legislative action, clinical research, and survey documentation. The Women's Health in the Dental School Curriculum study (1999) followed a similar study (1996) of medical school curricula. Both of these major efforts resulted from statutory mandates in the National Institutes of Health Revitalization Act of 1993 (updated October 2000). A major study of the Institute of Medicine (IOM) National Academy of Sciences in 2001 concluded that "the study of sex differences is evolving into a mature science." This IOM study documented the scientific basis for gender-related policy and research and challenged the dental research enterprise to conduct collaborative, cross-disciplinary research on gender-related issues in oral health, disease, and disparities. This report chronicles some of the factors that have and continue to influence concepts of women's oral health in dental education, research, and practice. Gender issues related to women's health are no longer restricted to reproductive issues but are being considered across the life span and include psychosocial factors that impact women's health and treatment outcomes.

This paper investigates the relationship between anticipation that employers may discriminate against certain people (not specified, but not specifically the respondent) according to race, colour of skin, religion or cultural background, and self-rated health, adjusting for social capital in the form of generalised (horizontal) trust in other people. It also investigates ethnic differences in anticipated discrimination in relation to self-rated health. The 2004 Public Health Survey in the Scania region of Sweden is a cross-sectional study. Twenty-seven thousand nine hundred and sixty-three respondents aged 18-80 years answered a postal questionnaire, which represents 59% of the random sample. A logistic regression model was used to assess the association between anticipated discrimination and self-rated health. Multivariate analyses of self-rated health were performed in order to investigate the importance of possible confounders (age, country of origin, education, economic stress, and generalised trust) on this association. Of the men and the women, 28.7 and 33.2%, respectively, rated their health as poor. Of the respondents, 16.0 and 28.7% reported that they anticipated that 'most employers' or 'approximately 50% of employers' would discriminate, respectively. Respondents with high age, born outside Sweden, with low/medium education, economic stress, low horizontal trust, and with anticipation that most or approximately 50% of employers (among men born in Sweden and all women) would discriminate had significantly higher odds ratios of poor self-rated health. Multiple adjustments had a slight effect on the significant relationship between anticipated discrimination and poor self-rated health for both men and women. The introduction of generalised trust in the models reduced the odds ratios to a limited extent. In conclusion, the anticipation that employers may discriminate against certain people (not the respondent) according to race, colour of skin, religion or
Background With increasing life expectancy the number of people affected by multimorbidity rises. Knowledge of factors associated with health-related quality of life in multimorbid people is scarce. We aimed to identify the factors that are associated with self-rated health (SRH) in aged multimorbid primary care patients. Methods Cross-sectional study with 3,189 multimorbid primary care patients aged from 65 to 85 years recruited in 158 general practices in 8 study centers in Germany. Information about morbidity, risk factors, resources, functional status and socio-economic data were collected in face-to-face interviews. Factors associated with SRH were identified by multivariable regression analyses. Results Depression, somatization, pain, limitations of instrumental activities (iADL), age, distress and Body Mass Index (BMI) were inversely related with SRH. Higher levels of physical activity, income and self-efficacy expectation had a positive association with SRH. The only chronic diseases remaining in the final model were Parkinson’s disease and neuropathies. The final model accounted for 35% variance of SRH. Separate analyses for men and women detected some similarities; however, gender specific variation existed for several factors. Conclusion In multimorbid patients symptoms and consequences of diseases such as pain and activity limitations, as well as depression, seem to be far stronger associated with SRH than the diseases themselves. High income and self-efficacy expectation are independently associated with better SRH and high BMI and age with low SRH. Trial registration MultiCare Cohort study registration:ISRCTN89818205.

Background Acculturation is for indigenous peoples related to the process of colonisation over centuries as well as the on-going social transition experienced in the Arctic today. Changing living conditions and lifestyle affect health in numerous ways in Arctic indigenous populations. Self-rated health (SRH) is a relevant variable in primary health care and in general public health assessments and monitoring. Exploring the relationship between acculturation and SRH in indigenous populations having experienced great societal and cultural change is thus of great importance. Methods The principal method in the Survey of Living Conditions in the Arctic (SLiCA) was standardised face-to-face interviews using a questionnaire. Very high overall participation rates of 83% were obtained in Greenland and Alaska, whilst a more conventional rate of 57% was achieved in Norway. Acculturation was conceptualised as certain traditional subsistence activities being of lesser importance for people’s ethnic identity, and poorer spoken indigenous language ability (SILA). Acculturation was included in six separate gender- and country-specific ordinal logistic regressions to assess qualitative effects on SRH. Results Multivariable analyses showed that acculturation significantly predicted poorer SRH in Greenland. An increased subsistence score gave an OR of 2.32 (P<0.001) for reporting poorer SRH among Greenlandic men, while an increased score for Greenlandic women generated an OR of 1.71 (P=0.01). Poorer SILA generated an OR of 1.59 in men (p=0.03). In Alaska, no evidence of acculturation effects was detected among Iñupiaq men. Among Iñupiaq women, an increased subsistence score represented an increased odds of 73% (p=0.026) for reporting poorer SRH. No significant effects of acculturation on SRH were detected in Norway. Conclusions This study shows that aggregate acculturation is a strong risk factor for poorer SRH among the Kalaallit of Greenland and female Iñupiat of Alaska, but

Personality traits change across the lifespan, and trait change, in addition to trait level, may be related to health. Longitudinal data from the Hawaii Personality and Health Cohort were used to investigate associations between changes in traits and self-rated health (SRH). Participants (N = 733, Mage = 44.4) completed measures of the Big Five personality traits and SRH twice approximately 3 years apart. Personality trait changes were associated with SRH change. Additionally, increases on Agreeableness, Conscientiousness, and Openness, and decreases on Neuroticism, predicted increases in SRH, even when controlling for gender and education. Relating correlated trait change at mid-life, when traits reach peak stability, to a consequential health outcome such as SRH change, demonstrates the value of treating both traits and health indicators as dynamic variables.

Health literacy skills are important for health and self-management for people with chronic illness. Neighborhood social capital can provide resources, such as access to information and informal social control over unhealthy behavior. The benefit of these resources, and the access people have to these resources, might depend on levels of health literacy. We investigated whether neighborhood social capital is differentially related to the health of people with chronic illness according to health literacy skills. This study focused on health literacy skills in 4 domains related to the ability to access and understand health information and to the ability to perform self-management. We found a significant positive interaction between social capital and health literacy skills for accessing and understanding health information. This suggests that health literacy enhances people's ability to gain access to and use neighborhood resources to benefit health. There was no interaction effect between social capital and health literacy skills in the other 2 domains. More research is needed to investigate how people with chronic illness can benefit from knowledge, support, and other social resources for health and self-management also whether they have limited health literacy skills.

Objectives We investigated the associations between self-rated health and social capital among Croatian high school students. Design A cross-sectional survey among high school students was carried out in the 2013–2014 school year. Setting High schools in Croatia. Participants Subjects were 3427 high school students (1688 males and 1739 females), aged 17–18 years. Main outcome measure Self-rated health was assessed by the single item: “How do you perceive your health?”. Possible responses were arranged along a five-item Likert-type scale: 1 very poor, 2 poor, 3 fair, 4 good, 5 excellent. The outcome was binarised as ‘good health’ (excellent, good or fair) versus ‘poor health’ (poor or very poor). Methods We calculated ORs and 95% CIs for good self-rated health associated with family, neighbourhood and school social capital, while adjusting for gender, self-perceived socioeconomic status, psychological distress, physical activity and body mass index. We used generalised estimating equations using an exchangeable correlation matrix with robust SEs. Results Good self-rated health was significantly associated with higher family social capital (OR 2.43; 95% CI 1.55 to 3.80), higher neighbourhood trust (OR 2.02; 95% CI 1.48 to 2.76) and higher norms of reciprocity at school (OR 1.79; 95% CI 1.13 to 2.84). When all of the social capital variables were entered simultaneously, good self-rated health remained significantly associated with higher family social capital (OR 1.98; 95% CI 1.19 to 3.30), neighbourhood trust (OR 1.77; 95% CI 1.25 to 2.51) and reciprocity at school (OR 1.71; 95% CI 1.08 to 2.73). Conclusions Higher levels of social capital were independently associated with higher self-rated health among youth. Intervention and policies that leverage community social capital might serve as an avenue for health promotion in youth. PMID:26056122

Nursing staff are exposed to stressful work load which in turn is associated with poor physical and psychological health, sickness absence and job exit. The effort-reward imbalance (ERI) model is a validated approach to measure chronic psychosocial work stress by identifying nonreciprocity between occupational efforts spent and rewards received, and has been found to predict poor health. The aim of this cross-sectional study (n = 367 nurses and nurses aides) was first to test the psychometric properties of the Danish questionnaire measuring ERI, and secondly to analyse whether psychosocial work stress is associated with six indicators of poor self-rated health. Results derived from confirmatory factor analysis indicate satisfying psychometric properties. Elevated risks of poor self-rated health (odds ratios varying from 1.92 to 4.76) are observed in nursing staff characterized by high effort in combination with low reward. Effects are enhanced in those respondents who additionally exhibit a high level of work-related overcommitment. In conclusion, despite methodological limitations, this study contributes to the validation of the ERI questionnaire in Danish language. Furthermore, by documenting associations with poor self-rated health, it supports efforts of theory-guided prevention of work stress in health care professions.

Although there has been extensive research on the adverse impacts of perceived discrimination on health, it remains unclear how perceived discrimination gets under the skin. This paper develops a comprehensive structural equation model (SEM) by incorporating both the direct effects of perceived discrimination on self-rated health (SRH), a powerful predictor for many health outcomes, and the indirect effects of perceived discrimination on SRH through health care system distrust, neighborhood social capital, and health behaviors and health conditions. Applying SEM to 9,880 adults (aged between 18 and 100) in the 2008 Southeastern Pennsylvania Household Health Survey, we not only confirmed the positive and direct association between discrimination and poor or fair SRH, but also verified two underlying mechanisms: 1) perceived discrimination is associated with lower neighborhood social capital, which further contributes to poor or fair SRH; and 2) perceived discrimination is related to risky behaviors (e.g., reduced physical activity and sleep quality, and intensified smoking) that lead to worse health conditions, and then result in poor or fair SRH. Moreover, we found that perceived discrimination is negatively associated with health care system distrust, but did not find a significant relationship between distrust and poor or fair SRH.

Background China is in the midst of history's largest flow of rural-urban migration in the world; a flow that includes growing numbers of children and adolescents. Their health status is an important public health issue. This study compares self-rated physical and mental health of migrant and local adolescents in China, and examines to what extent layered social connections account for health outcomes. Methods In 2010, we conducted a cross-sectional study among middle school students in Pudong New Area, Shanghai. Information about health status, social connections, and demographic factors were collected using a questionnaire survey. After controlling for sociodemographic factors, we used the t-test, Chi-square analysis, and a series of regression models to compare differences in health outcomes and explore the effects of social connections. Results Migrant adolescents reported significantly higher rates of good physical health. However, they also had significantly fewer social connections, lower self-esteem, and higher levels of depression than their native peers. Family cohesion was associated with depressive symptoms and low self-esteem among all adolescents; peer association and social cohesion played major roles in migrants' well-being. Gender, age, and socioeconomic (SES) factors also affected adolescents' self-rated physical and mental health. Conclusions Self-rated data suggest that migrant adolescents enjoy a physical health advantage and a mental health disadvantage. Layered social connections, such as peer association and social cohesion, may be particularly important for migrants. A public health effort is required to improve the health status of migrant youth.

Recent discourses in the area of neighbourhood effects on health have advocated for a relational perspective of space and place, focussing on the mutually reinforcing and reciprocal relationship between the environment and the individual. An example of such relationship is that of the interaction between area deprivation and individual ethnicity on reports of self-rated health, which we explored using cross-sectional data from the 2007 Citizenship Survey linked to the 2001 UK census. We aimed to examine whether the association between area deprivation and poor self-rated health differs for ethnic minority groups, as compared to white British people. Following from this, we also examined whether possible differential associations were mediated by ethnic density effects and perceptions of and satisfaction with neighbourhood characteristics. Results of random effects multilevel logistic regression models showed the detrimental association between area deprivation and self-rated health to be of greater magnitude and stronger for white British people than for ethnic minority people. This differential association was not mediated by ethnic density effects or perceptions of and satisfaction with neighbourhood characteristics.

Background Few studies have examined the psychosocial mechanisms through which self-reported discrimination may influence the health status of Latinos. Purpose This study examined the mediating role of subjective social status in the US and psychological distress on the relation between everyday discrimination and self-rated physical health, and the moderating role of gender and ethnicity. Methods A US population-based sample of Latinos (N= 2,554) was drawn from the National Latino and Asian American Study. Respondents completed measures of everyday discrimination, subjective social status, psychological distress, and self-rated physical health. Results Path analysis revealed that among the total sample, subjective social status and psychological distress sequentially mediated the effect of everyday discrimination on self-rated physical health. Psychological distress was a more consistent mediator across Latino subgroups. Gender and ethnicity moderated the mediation model. Conclusions This study provides a systematic examination of how psychosocial mechanisms may operate differently or similarly across Latino subgroups. PMID:23054945

Background This study explores the relationships between social capital, self-rated health, and happiness and suggests ways to improve the happiness level of a community. Methods The survey was conducted with 445 people using stratified random sampling in a medium-sized city in Korea. Collected information included socio-demographic characteristics, social capital, self-rated health, and happiness. Results Among the demographic characteristics, age had a statistically significant association with happiness level. People in their 40s (OR = 0.33, 95% CI = 0.13–0.88) and 50s (OR = 0.19, 95% CI = 0.06–0.57) were less happy than people of other ages. Married people (OR = 4.58, CI = 1.99–10.53) were more likely to have a high happiness level compared to unmarried people. Cognitive social capital (OR = 1.34, CI = 1.19–1.51) and self-rated health (OR = 2.22, CI = 1.59–3.09) were positively associated with happiness. Conclusion The results suggest that social capital and level of health are determinants of subjective happiness. Public policies and programs for improving social capital are needed to support happiness among community residents. PMID:26770893

Background The objective of this study is to estimate occupational differences in self-rated health, both in cross-section and over time, among older individuals. Methods We use hierarchical linear models to estimate self-reported health as a function of 8 occupational categories and key covariates. We examine self-reported health status over 7 waves (12 years) of the Health and Retirement Study. Our study sample includes 9,586 individuals with 55,389 observations. Longest occupation is used to measure the cumulative impact of occupation, address the potential for reverse causality, and allow the inclusion of all older individuals, including those no longer working. Results Significant baseline differences in self-reported health by occupation are found even after accounting for demographics, health habits, economic attributes, and employment characteristics. But contrary to our hypothesis, there is no support for significant differences in slopes of health trajectories even after accounting for dropout. Conclusions Our findings suggest that occupation-related differences found at baseline are durable and persist as individuals age. PMID:19196689

Introduction: The measurement of health status of the elderly remains one important topic. Self-rated health status (SRH) is considered to be a simple indicator to measure the health status of the old population. But some researchers still take a skeptical view about its reliability. This study aims to investigate the association between SRH indicator and health status of the elderly and discuss its subsequent public health implications. Methods: In a total 1096 people who were 60 years of age or older from 1784 households from a suburban area of Beijing were interviewed using multistage stratified cluster sampling. SRH was measured by a single question “please choose one point in this 0–100 scale, which can best represent your health today.” The disease status and physical functional status were also obtained. A multiple linear regression was conducted to test the associate between SRH and individual’s disease/functional status. Results: The average of SRH scores of the elderly was 72.49 ± 15.64 (on a 1–100 scale). The SRH scores declined not only with the severity of self-reported mental/disease status, but also with the decrease of physical functional status. Multiple linear regression showed that after adjustment for other variables, 2-week sickness, chronic diseases, hospitalization, and ability of self-care (washing and dressing) were able to explain 35% of the variation in SRH among the elderly. Among them, disease status and self-care ability were the most powerful predictor of SRH. After adjusting other variables, physical functional status could explain only 5% of the variation in SRH. Conclusion: Self-rated health reflects the disease/functional health status of the elderly. It is an easy-to-implement variable and it can reduce both recall bias and investigator bias, thus being widely used in health surveys. It is a cost-effective means of measuring the health status. However, the comparability of SRH in different populations should be

Poverty, both absolute and relative, is associated with poorer health. This is of particular concern in middle- and low-income countries facing a significant and growing burden of disease. There has been limited research specifically on whether interventions that increase income may foster better health outcomes. The establishment of a "living wage" apparel factory in the Dominican Republic provided a minimum income standard for factory workers, thus creating a natural experiment through which to study the effects of increased income on health indicators. The primary component of the intervention was a 350% wage increase, but apparel workers in the intervention factory also received education and professional development and were exposed to an enhanced occupational health and safety program. Workers at the intervention factory (n = 99) were compared with workers at a matched apparel factory (n = 105). Data were collected via in-person interviews in July and August of 2011, which was 15-16 months after workers were initially hired at the intervention site. Primary analyses used employment at the intervention factory as the independent variable and examined associations with two dependent variables: subjective social status and self-rated health. Results showed that receiving a 350% higher wage was associated with substantially higher subjective social status scores, as well as higher global and comparative self-rated health scores; effects were strongest in women. Subjective social status and self-rated health are associated with future health outcomes, so these results indicate that income increases for apparel workers may have positive long-term health outcomes, particularly for women.

A growing body of research seeks to understand how language bias in survey research impacts our abilities to make generalizations in the study of racial and ethnic disparities. This research uses a wording experiment to assess self-rated health among a representative study of the Latino population (n=1,200). Our analysis shows that by manipulating only the translation of the category fair health into Spanish we are able to directly test the hypothesis that the translation of fair to regular in Spanish suppresses Latino self-rated health. We find convincing evidence through the use of logistic and multinomial logistic regressions that respondents provided with the term regular report poorer health when compared to those who were given the alternative translation of mas o menos. We also find that this translation effect is driven solely by a movement of respondents to choose fair rather than good health, which can in fact explain lower than expected health status rates in studies looking to explore differences between Latinos and non-Latinos. This research informs the study of racial and ethnic disparities, providing a detailed explanation for mixed findings in the Latino health disparities literature. PMID:26439110
Much of the literature on mental and physical health among religious LGB individuals has relied on small-N convenience samples. This study takes advantage of a unique, large-N, population-based dataset to test the relationship between religious identity, religious activity, and health, with a specific emphasis on Utah Mormons. In a surprising finding, Mormon LGBs report better mental health than non-Mormon LGBs, while their self-rated and physical health is not significantly different. However, there is some evidence that Mormon LGBs derive fewer health benefits from church attendance than their non-LGB Mormon counterparts. These results may nuance the conventional wisdom regarding the health dynamics of LGB individuals who identify with a conservative, heteronormative religious tradition, and plausible explanations are discussed.
OBJECTIVES: With an increasing number of studies highlighting regional social capital (SC) as a determinant of health, many studies are using multi-level analysis with merged and averaged scores of community residents’ survey responses calculated from community SC data. Sufficient examination is required to validate if the merged and averaged data can represent the community. Therefore, this study analyzes the validity of the selected indicators and their applicability in multi-level analysis. METHODS: Within and between analysis (WABA) was performed after creating community variables using merged and averaged data of community residents’ responses from the 2013 Community Health Survey in Korea, using subjective self-rated health assessment as a dependent variable. Further analysis was performed following the model suggested by WABA result. RESULTS: Both E-test results (1) and WABA results (2) revealed that single-level analysis needs to be performed using qualitative SC variable with cluster mean centering. Through single-level multivariate regression analysis, qualitative SC with cluster mean centering showed positive effect on self-rated health (0.054, p<0.001), although there was no substantial difference in comparison to analysis using SC variables without cluster mean centering or multi-level analysis. CONCLUSIONS: As modification in qualitative SC was larger within the community than between communities, we validate that relational analysis of individual self-rated health can be performed within the group, using cluster mean centering. Other tests besides the WABA can be performed in the future to confirm the validity of using community variables and their applicability in multi-level analysis. PMID:27292102

Active traveling to a daily occupation means that an individual uses an active way of traveling between two destinations. Active travel to work or other daily occupations offers a convenient way to increase physical activity levels which is known to have positive effects on several health outcomes. Frequently used concepts in city planning and regional planning today are to create environments for active commuting and active living. Even then, little research has focused on traveling modes and subjective health outcomes such as self-rated health (SRH). This study aimed to explore and investigate associations between travel mode and health-related outcomes, such as self-rated health (SRH), body mass index (BMI) and overall physical activity, in an adult population in Sweden. A cross-sectional study was conducted in a randomly selected population-based sample (n = 1786, age 45-75 years); the respondents completed a questionnaire about their regular travel mode, demographics, lifestyle, BMI and SRH. Chi-square tests and logistic regressions found that inactive traveling was associated with poor SRH, a greater risk of obesity or being overweight and overall physical inactivity. In addition, lifestyle factors, such as choice of food and smoking habits, were associated with SRH, BMI and overall physical activity.
Introduction Women have in general poorer self-rated health than men. Both material and psychosocial conditions have been found to be associated with self-rated health. We investigated whether two such factors, financial insecurity and condescending treatment, could explain the difference in self-rated health between women and men. Methods The association between the two factors and self-rated health was investigated in a population-based sample of 35,018 respondents. The data were obtained using a postal survey questionnaire sent to a random sample of men and women aged 18-75 years in 2008. The area covers 55 municipalities in central Sweden and the overall response rate was 59%. Multinomial odds ratios for poor self-rated health were calculated adjusting for age, educational level and longstanding illness and in the final model also for financial insecurity and condescending treatment. Results The prevalence of poor self-rated health was 7.4% among women and 6.0% among men. Women reported more often financial insecurity and condescending treatment than men did. The odds ratio for poor self-rated health in relation to good self-rated health was 1.29 (95% CI: 1.17-1.42) for women compared to men when adjusted for age, educational level and longstanding illness. The association became, however, statistically non-significant when adjusted for financial insecurity and condescending treatment. Conclusion The present findings suggest that women would have as good self-rated health as men if they had similar financial security as men and were not treated in a condescending manner to a larger extent than men. Longitudinal studies are, however, required to confirm this conclusion. PMID:22937777

The article seeks to investigate patterns of performance and relationships between grip strength, gait speed and self-rated health, and investigate the relationships between them, considering the variables of gender, age and family income. This was conducted in a probabilistic sample of community-dwelling elderly aged 65 and over, members of a population study on frailty. A total of 689 elderly people without cognitive deficit suggestive of dementia underwent tests of gait speed and grip strength. Comparisons between groups were based on low, medium and high speed and strength. Self-related health was assessed using a 5-point scale. The males and the younger elderly individuals scored significantly higher on grip strength and gait speed than the female and oldest did; the richest scored higher than the poorest on grip strength and gait speed; females and men aged over 80 had weaker grip strength and lower gait speed; slow gait speed and low income arose as risk factors for a worse health evaluation. Lower muscular strength affects the self-rated assessment of health because it results in a reduction in functional capacity, especially in the presence of poverty and a lack of compensatory factors.
Evidence suggests that living in a socioeconomically deprived neighborhood is associated with worse health. Yet most research relies on cross-sectional data, which implicitly ignore variation in longer-term exposure that may be more consequential for health. Using data from the 1970 to 2011 waves of the Panel Study of Income Dynamics merged with census data on respondents' neighborhoods (N = 1,757), this study estimates a marginal structural model with inverse probability of treatment and censoring weights to examine: (1) whether cumulative exposure to neighborhood disadvantage from birth through age 17 affects self-rated health in early adulthood, and (2) the extent to which variation in such exposure helps to explain racial disparities therein. Findings reveal that prolonged exposure to neighborhood disadvantage throughout childhood and adolescence is strikingly more common among nonwhite versus white respondents and is associated with significantly greater odds of experiencing an incidence of fair or poor health in early adulthood.

This paper aims to clarify the association between various social capital components at the municipal level (community social capital) and two quality-of-life factors at the individual level [individual self-rated life satisfaction and self-rated health (SRH)] based on data from a nationwide social capital survey that the authors carried out in 2013 in Japan (N = 3406 in 99 municipalities). The survey covers residents in Japan between the ages of 20 and 79 years. We focus on both contextual social capital and household income inequality in terms of the Gini coefficient at the municipality level since, to the best of our knowledge, no paper has explicitly dealt with municipalities in Japan as the units of contextual social capital and the Gini. Our analyses show that the subjective life satisfaction of individuals, after controlling for socioeconomic status and health at the individual level, is associate with both an income gap and social capital at the municipal level. Every component of community social capital in this study except for generalized reciprocity, both cognitive (generalized trust, particularized trust, and particularized reciprocity), and structural (three types of group participation and daily contacts with neighbors, friends/acquaintances, and colleagues), and the Gini coefficient on earned income were associated with self-rated life satisfaction at the individual level with statistical significance. However, SRH is associated only with cognitive social capital at the community level. SRH has no significant association with structural components of community social capital or with a community income gap in terms of the Gini coefficient on personal income. Judging from the results of estimates in the study, most of the components of community social capital at the municipal level seem to play an important role in enhancing self-rated life satisfaction. Life satisfaction may be associated with the broad atmosphere of the municipal level where one
Background The association between self-rated health (SRH) and mortality is well documented in the literature, but studies on the subject among young adults in Latin America are rare, as are those evaluating this association using repeated SRH measures, beyond the baseline measurement. This study aims to evaluate the association between SRH evaluated at three data collection stages and mortality. Methods Cox regression models were used to examine the association between SRH (Very good, Good, Fair/Poor) varying over time and mortality, over a 10 year period, in a cohort of non-faculty civil servants at a public university in Rio de Janeiro, Brazil (Pró-Saúde Study, n = 4009, men = 44.4%). Results About 40% of the population changed their self-rating over the course of follow-up. After adjustment for self-reported physician-diagnosed chronic diseases and other covariates, men who reported “Fair/Poor” SRH showed relative hazard of death of 2.13 (CI95% 1.03-4.40) and women, 3.43 (CI95% 1.23-9.59), as compared with those who reported “Very good” SRH. Conclusions In a population of young adults, our findings reinforce the role of SRH as a predictor of mortality, even controlling for objective measures of health. PMID:22905737

Objective: To examine the influence of sociodemographic and neighbourhood factors on self rated health, quality of life, and perceived opportunities for change (as one measure of empowerment) in rural Irish communities. Design: Pooled data from cross sectional surveys two years apart. Setting: Respondents in four randomly selected rural district electoral divisions with a population size of between 750 and 2000. Participants: 1738 rural dwellers aged 15–93, 40.5% men, interviewed at two time points. Main outcome measures: Determinants of self rated health (SRH), quality of life (QOL), and perceived opportunities for change, rated on a closed option Likert scale and assessed in multivariate logistic regression models. Main results: Overall 23.8% of the sample reported poor SRH, 22.2% poor QOL, and 50.1% low perceived opportunities for change. Low financial security and dissatisfaction with work were each significantly associated with poor SRH (OR = 1.96 (1.50 to 2.56) and 1.54 (1.11 to 2.14)), with poor QOL (OR = 2.04 (1.56 to 2.68) and 1.87 (1.34 to 2.61). Concern about access to public services was significantly predictive of SRH (OR = 1.47 (1.11 to 1.94)) rather than access to health care (that is, hospital and GP services). There were distinct sex specific patterns and a generational effect for educational status in men. Variables associated with social networks and social support were less strongly predictive of SRH and QOL when economic measures were accounted for. Conclusion: Inter-relations between indicators of health status, wellbeing, and deprivation are not well studied in rural communities. Material deprivation has a direct influence on both health status and quality of life, although immediate sources of support are relatively well preserved. PMID:15483305

This study examines the physical health status of immigrants with specific considerations of Asian and Hispanic populations and explores possible mechanisms through which health outcomes of interest can be explained. Analyses of the National Health Interview Surveys (NHIS) of 2000 and 2001 revealed that foreign-born individuals reported fewer chronic diseases (hypertension, heart disease, asthma, cancer and diabetes) and had lower prevalences of various chronic diseases compared with U.S.-born whites, controlling for possible confounders and mediators. However, U.S-born minority groups did not show the health advantage seen in foreign-born immigrants, reflecting the importance of nativity distinctions in studying immigrant health. Despite having fewer chronic diseases, foreign-born Asians were more likely to rate their health negatively relative to their U.S.-born counterparts and to U.S.-born whites. In addition, our findings provide evidence that failure to consider comorbid status may attenuate the nativity effect on certain chronic diseases.

Rationale The social, emotional, and mental health benefits associated with gardening have been well documented. However, the processes underlying the relationship between garden participation and improvements in health status have not been sufficiently studied. Methods Using population-based survey data (n = 469 urban residents), objective street environment data, and area-level measures, this research used a path analytic framework to examine several theoretically based constructs as mediators between gardening history and self-reported health. Results The results showed that garden participation influenced health status indirectly through social involvement with one’s community, perceived aesthetic appeal of the neighborhood, and perceived collective efficacy. Gardeners, compared to non-gardeners, reported higher ratings of neighborhood aesthetics and more involvement in social activities, whereas aesthetics and involvement were associated with higher ratings of collective efficacy and neighborhood attachment. Collective efficacy, but not neighborhood attachment, predicted self-rated health. Gardening also directly influenced improved fruit and vegetable intake. The physical and social qualities of garden participation may therefore stimulate a range of interpersonal and social responses that are supportive of positive ratings of health. Conclusion This research suggests that community planners and health professionals should aim to strengthen the social and aesthetic relationships while designing environments and policies as a way to ignite intermediate processes that may lead to improved health status.

The aim of this study was to examine whether changes over time in reported area crime and perceived area safety were related to self-rated general health and physical activity (PA), in order to provide support for a causal relationship between social safety and health. Additionally, we investigated whether social cohesion protects the residents against the negative impact of unsafe areas on health and PA. Multilevel logistic regression analyses were performed on Dutch survey data, including 47,926 respondents living in 2974 areas. An increase in area level unsafety feelings between 2009 and 2011 was associated with more people reporting poor general health in 2012 in that area, but was not related to PA. Changes in reported area crime were not related to either poor general health or PA. The social cohesion in the area did not modify the effect of changes in social safety on health and PA. The results suggest that tackling feelings of unsafety in an area might contribute to the better general health of the residents. Because changes in area social safety were not associated with PA, we found no leads that such health benefits were achieved through an increase in physical activity.

Previous research suggests that higher incomes, safe workplaces, job security and healthcare access all contribute to favorable health. Reflecting the interest of economic and political sociologists in power relations and institutions, union membership has been linked with many such influences on health. Nevertheless, the potential relationship…

Online search for consumer health information is a public health concern. General-purpose search engines have historically returned health-related query results of dubious relevance and quality. Meanwhile, consumers have become increasingly reliant on and trusting of these engines. General-purpose search engines have attempted to make their interfaces more consumer-friendly with respect to consumer health queries and their results more relevant and trustworthy. We illustrate the characteristics of the evolving health search landscape using network visualization.

The aim of this study was to analyse concordance between Danish adults' recorded diet quality and their own assessment of the healthiness and to examine socio-demographic, health and behavioural characteristics associated with an optimistic or pessimistic self-assessment. Data were derived from The Danish National Survey of Diet and Physical Activity 2011-2013 and included a random sample of 3014 adults (18-75 y). Diet quality was evaluated on the basis of seven-day pre-coded food diaries and categorised 'unhealthy', 'somewhat healthy' and 'healthy'. Self-assessment of the healthiness of own diets was registered via personal interviews and categorised healthy enough 'to a high degree', 'to some degree' or 'not at all/only partly'. Highly and somewhat optimistic self-assessment, respectively, were defined as assessing own diets as healthy enough to a high degree or to some degree while having unhealthy diets. Highly and somewhat pessimistic self-assessment, respectively, were defined as assessing own diets as not healthy enough or healthy enough to some degree while having healthy diets. Multiple logistic regression models were used to examine characteristics associated with optimistic and pessimistic self-assessments, respectively. Among individuals with unhealthy diets, 13% were highly optimistic and 42% somewhat optimistic about the healthiness of their diets. Among individuals with healthy diets, 14% were highly pessimistic and 51% somewhat pessimistic about the healthiness of their diets. Highly optimistic self-assessment was associated with increasing age, excellent self-rated health, normal weight and a moderate activity level. Highly pessimistic self-assessment was associated with decreasing age, good self-rated health and being obese. The findings indicate that people seem to use personal health characteristics as important references when assessing the healthiness of their diets.

Objectives. We investigated how much the Human Development Index (HDI), a global measure of development, modifies the effect of education on self-reported health. Methods. We analyzed cross-sectional World Health Survey data on 217 642 individuals from 49 countries, collected in 2002 to 2005, with random-intercept multilevel linear regression models. Results. We observed greater positive associations between educational levels and self-reported good health with increasing HDI. The magnitude of this effect modification of the education–health relation tended to increase with educational attainment. For example, before adjustment for effect modification, at comparable HDI, on average, finishing primary school was associated with better general health (b = 1.49; 95% confidence interval [CI] = 1.18, 1.80). With adjustment for effect modification by HDI, the impact became 4.63 (95% CI = 3.63, 5.62) for every 0.1 increase in HDI. Among those who completed high school, these associations were, respectively, 5.59 (95% CI = 5.20, 5.98) and 9.95 (95% CI = 8.89, 11.00). Conclusions. The health benefits of educational attainment are greater in countries with greater human development. Health inequalities attributable to education are, therefore, larger in more developed countries. PMID:24028233

Introduction Nordic countries do not have the smallest health inequalities despite egalitarian social policies. A possible explanation for this is that drivers of class differences in health such as financial strain and labour force status remain socially patterned in Nordic countries. Methods Our analyses used data for working age (25–59) men (n = 48,249) and women (n = 52,654) for 20 countries from five rounds (2002–2010) of the European Social Survey. The outcome was self-rated health in 5 categories. Stratified by gender we used fixed effects linear regression models and marginal standardisation to instigate how countries varied in the degree to which class inequalities were attenuated by financial strain and labour force status. Results and Discussion Before adjustment, Nordic countries had large inequalities in self-rated health relative to other European countries. For example the regression coefficient for the difference in health between working class and professional men living in Norway was 0.34 (95% CI 0.26 to 0.42), while the comparable figure for Spain was 0.15 (95% CI 0.08 to 0.22). Adjusting for financial strain and labour force status led to attenuation of health inequalities in all countries. However, unlike some countries such as Spain, where after adjustment the regression coefficient for working class men was only 0.02 (95% CI −0.05 to 0.10), health inequalities persisted after adjustment for Nordic countries. For Norway the adjusted coefficient was 0.17 (95% CI 0.10 to 0.25). Results for women and men were similar. However, in comparison to men, class inequalities tended to be stronger for women and more persistent after adjustment. Conclusions Adjusting for financial security and labour force status attenuates a high proportion of health inequalities in some counties, particularly Southern European countries, but attenuation in Nordic countries was modest and did not improve their relative position.

Little is known regarding the longitudinal effects of bonding and bridging social capital on health. This study examined the longitudinal associations of bonding and bridging social capital with self-rated health, depressive mood, and cognitive decline in community-dwelling older Japanese. Data analyzed in this study were from the 2010 (baseline) and 2012 (follow-up) Hatoyama Cohort Study. Bonding social capital was assessed by individual perception of homogeneity of the neighborhood (the level of homogeneity among neighbors) and of networks (the amount of homogeneous personal networks) in relation to age, gender, and socioeconomic status. Bridging social capital was assessed by individual perception of heterogeneity of networks (the amount of heterogeneous personal networks) in relation to age, gender, and socioeconomic status. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the effects of baseline social capital on poor health outcome at follow-up by logistic regression analysis. In total, 681 people completed baseline and follow-up surveys. The mean age of participants was 71.8 ± 5.1 years, and 57.9% were male. After adjusting for sociodemographics, lifestyle factors, comorbidity, functional capacity, baseline score of each outcome, and other bonding/bridging social capital, stronger perceived neighborhood homogeneity was inversely associated with poor self-rated health (OR = 0.55, 95% CI = 0.30-1.00) and depressive mood assessed by the Geriatric Depression Scale (OR = 0.58, 95% CI = 0.34-0.99). When participants who reported a depressive mood at baseline were excluded, stronger perceived heterogeneous network was inversely associated with depressive mood (OR = 0.40, 95% CI = 0.19-0.87). Neither bonding nor bridging social capital was significantly associated with cognitive decline assessed by the Mini-Mental State Examination. In conclusion, bonding and bridging social capital affect health in different ways, but they both have
Background This paper has two objectives. Firstly, it provides an overview of the social network module, data collection procedures, and measurement of ego-centric and complete-network properties in the Korean Social Life, Health, and Aging Project (KSHAP). Secondly, it directly compares the KSHAP structure and results to the ego-centric network structure and results of the National Social Life, Health, and Aging Project (NSHAP), which conducted in-home interviews with 3,005 persons 57 to 85 years of age in the United States. Methods The structure of the complete social network of 814 KSHAP respondents living in Township K was measured and examined at two levels of networks. Ego-centric network properties include network size, composition, volume of contact with network members, density, and bridging potential. Complete-network properties are degree centrality, closeness centrality, betweenness centrality, and brokerage role. Results We found that KSHAP respondents with a smaller number of social network members were more likely to be older and tended to have poorer self-rated health. Compared to the NSHAP, the KSHAP respondents maintained a smaller network size with a greater network density among their members and lower bridging potential. Further analysis of the complete network properties of KSHAP respondents revealed that more brokerage roles inside the same neighborhood (Ri) were significantly associated with better self-rated health. Socially isolated respondents identified by network components had the worst self-rated health. Conclusions The findings demonstrate the importance of social network analysis for the study of older adults’ health status in Korea. The study also highlights the importance of complete-network data and its ability to reveal mechanisms beyond ego-centric network data. PMID:25217892

Aim To examine the relationship between quality of life, self-rated health, and well-being and to establish the relationship between discontent with familial financial situation and health in adolescents living in the Tuzla Canton. Method The study comprised a random sample of 356 high school students aged 16, coming from 15 different classes of 16 high schools in the Tuzla municipality. Data were obtained using a validated self-reporting questionnaire on demographic and socioeconomic background, structure, and dynamics of the adolescent’s family, life-style, perception, and satisfaction with the financial situation and current health status, as well as social relationships and health care provided in school settings. Results In 11% (n = 40) of students’ households several poverty indicators were present. Twenty three percent (n = 82) of the examinees were dissatisfied with the financial situation in their families, and 73% of them came from local, non-refugee families. They presented with progressive symptoms of unhappiness and expressed discontent with their health condition, and even self-hate in comparison with adolescents who were satisfied with the financial situation in their families (χ2 = 21.5; P = 0.001). The prevalence of self-rated mental symptoms was significantly lower among adolescents who were satisfied with their financial situation than in those who were dissatisfied (symptoms of depression 57/274 vs 40/82, P = 0.001; sadness 73/274 vs 45/82, P = 0.001; moroseness 34/274 vs 19/82, P = 0.001; under-sedation 29/274 vs 18/82, P = 0.001; bad marks and school failures 31/274 vs 20/82, P = 0.001; suicidal attempts 11/274 vs 7/82, P = 0.001, respectively). Using linear regression analysis we found that adolescents’ satisfaction with the financial situation was a major factor predicting depression (OR, 1.57; 95% CI, 1.158-1.855), loss of appetite (OR, 0.82; 95% CI, 0.561-1.235), distraction (OR, 1.19; 95% CI

Background: To examine whether stress management mediates the relationship between purpose in life and self-rated health status (SRH). Methods: A cross-sectional survey was conducted among 6840 teachers in 2013 in Guangzhou, China. Purpose in life was assessed through the Purpose in Life Subscale of the Psychological Well-being Scale. Stress management was assessed using the eight-item questionnaire adapted from the Health-promoting Lifestyle Profile II. SRH was assessed by the Suboptimal Health Measurement Scale Version 1.0. The mediation hypothesis was tested by the structural equation model for path analysis. Results: It was found that purpose in life had direct and indirect effects on SRH. The path analysis showed the total effect (β = 0.563) of purpose in life on SRH was comprised of a direct effect (β = 0.319) and an indirect effect (β = 0.244), which was mediated by stress management. Conclusions: By supporting the mediation hypothesis, our results indicate that stress management mediated the effect of purpose in life on SRH. Enhancement of teachers’ purpose in life and improvement of training skills of stress management should be incorporated in the strategy of improving teachers’ health. PMID:27438843
A recent systematic review and meta-analysis has shown the effect of indoor mildew odour on allergic rhinitis risk, but its relation to other common chronic health outcomes in adults has not been investigated. Therefore, it was aimed to examine the relationship of indoor mildew odour and common health outcomes in adults in a national and population-based setting. Data was retrieved from the United States National Health and Nutrition Examination Surveys, 2005-2006, including the available information on demographics, housing characteristics, self-reported health conditions and urinary concentrations of environmental chemicals. T test, chi-squared test and survey-weighted logistic regression modelling were performed. Of all American adults (n = 4979), 744 (15.1%) reported indoor mildew odour or musty smell in their households. People who reported indoor mildew odour or musty smell also reported poorer self-rated health, sleep complaints, chronic bronchitis, asthma attack, itchy rash, sneezing and poor vision. In addition, people who reported indoor mildew odour or musty smell also tended to reside in older housing that were built 20 years earlier. However, there were no significant statistical associations found between indoor mildew odour or musty smell and urinary concentrations of environmental chemicals, which was also found to be associated with old housing. People who lived in older housing with indoor mildew odour or musty smell tended to have chronic health problems. To protect occupants in old housing from chronic illnesses associated with indoor mildew odour, elimination of the odour sources should be explored in future research and therefore public health and housing programs. Graphical abstract Pathway from old housing to musty smell, environmental chemicals and then health outcomes.

Objective To assess the joint association of passive and active smoking with self-rated health and life satisfaction among Iranian children and adolescents. Methods Using a multistage random cluster sampling method, a representative sample of 14 880 school students were selected from urban and rural areas of 30 provinces of Iran. Data were gathered using a questionnaire, a weight scale and metre. Participants were classified into four groups based on their smoking patterns: ‘non-smoker’, ‘only active smoker’, ‘only passive smoker’ and ‘active and passive smoker’. Life satisfaction (LS) and self-rated health (SRH) were assessed by self-administered validated questionnaires based on the WHO-Global School-based student Health Survey (WHO-GSHS). Data were analysed using a t-test, χ2 test and multiple logistic regression. Results A total of 13 486 individuals (6640 girls and 6846 boys) out of 14 880 invited participated in the study (response rate 90.6%). LS and good SRH showed linearly negative associations with smoking status in both sexes. The proportions of LS and SRH categories were significantly different among all subsets of smoking status. Those classified as ‘non-smokers’ had the highest proportions of LS and good SRH, followed by ‘only passive smokers’ and ‘only active smokers’, while those with ‘active and passive smoking’ had the lowest proportions of LS and good SRH. In a multivariate model, students in the ‘active and passive smoking’ group had lower odds of LS (OR 0.43; 95% CI 0.32 to 0.57) and good SRH (OR 0.51; 95% CI 0.38 to 0.68) than those in the ‘non-smoker’ group. Students in the ‘only passive smoker’ group also had lower odds of LS (OR 0.75; 95% CI 0.67 to 0.83) and good SRH (OR 0.72; 95% CI 0.66 to 0.80) compared with the ‘non-smoker’ group. Conclusions Adolescents with different smoking habits and exposure patterns have poorer SRH and LS than non-smokers. Both active and passive smoking
Background Social conditions, social relationships and neighbourhood environment, the components of social capital, are important determinants of health. The objective of this study was to investigate the association of neighbourhood and individual social capital with consistent self-rated health in women between the first trimester of pregnancy and six months postpartum. Methods A multilevel cohort study in 34 neighbourhoods was performed on 685 Brazilian women recruited at antenatal units in two cities in the State of Rio de Janeiro, Brazil. Self-rated health (SRH) was assessed in the 1st trimester of pregnancy (baseline) and six months after childbirth (follow-up). The participants were divided into two groups: 1. Good SRH – good SRH at baseline and follow-up, and, 2. Poor SRH – poor SRH at baseline and follow-up. Exploratory variables collected at baseline included neighbourhood social capital (neighbourhood-level variable), individual social capital (social support and social networks), demographic and socioeconomic characteristics, health-related behaviours and self-reported diseases. A hierarchical binomial multilevel analysis was performed to test the association between neighbourhood and individual social capital and SRH, adjusted for covariates. Results The Good SRH group reported higher scores of social support and social networks than the Poor SRH group. Although low neighbourhood social capital was associated with poor SRH in crude analysis, the association was not significant when individual socio-demographic variables were included in the model. In the final model, women reporting poor SRH both at baseline and follow-up had lower levels of social support (positive social interaction) [OR 0.82 (95% CI: 0.73-0.90)] and a lower likelihood of friendship social networks [OR 0.61 (95% CI: 0.37-0.99)] than the Good SRH group. The characteristics that remained associated with poor SRH were low level of schooling, Black and Brown ethnicity, more children

It is hypothesized that unconditional (given without obligation) publicly funded financial credits more effectively improve health than conditional financial credits in high-income countries. We previously reported no discernible short-term impact of an employment-conditional tax credit for families on self-rated health (SRH) in adults in New Zealand. This study estimates the effect of an unconditional tax credit for families, called Family Tax Credit (FTC), on SRH in the same study population and setting. A balanced panel of 6900 adults in families was extracted from seven waves (2002-2009) of the Survey of Family, Income and Employment. The exposures, eligibility for and amount of FTC, were derived by applying government eligibility and entitlement criteria. The outcome, SRH, was collected annually. Fixed effects regression analyses eliminated all time-invariant confounding and adjusted for measured time-varying confounders. Becoming eligible for FTC was associated with a small and statistically insignificant change in SRH over the past year [effect estimate: 0.013; 95% confidence interval (CI) -0.011 to 0.037], as was an increase in the estimated amount of FTC by $1000 (effect estimate: -0.001; 95% CI -0.006 to 0.004). The unconditional tax credit for families had no discernible short-term impact on SRH in adults in New Zealand. It did not more effectively improve health status than an employment-conditional tax credit for families.

Despite advertised health warnings regarding the deadly hazards of smoking, many people have not heeded recommendations to quit smoking. We examined factors that affect self-rated subjective health status (SRH) scores among lifestyle, nutrient intake and biochemical parameters, and the association of SRH scores and smoking status in a large Korean adult population. Adjusted odd ratios for SRH were calculated for smoking status, selected biochemical data, and food and nutrient intake obtained using the 24-hr recall method after covariate adjustment in the 2007-2012 Korean National Health and Nutrition Examination Survey (27,534 men and women aged ≥ 20 yr). Age, sex, income, education, drinking, exercise and stress levels were associated with SRH scores, regardless of smoking status (P < 0.001). Interestingly, people in any smoking status groups considered the well-known indicators for metabolic diseases (HDL cholesterol, glucose, aspartate aminotransferase, and alanine aminotransferase in the circulation), and the intake of fiber, total vitamins A, and vitamin C as indicators of SRH. Especially in current smokers, higher intake of nutritious food groups such as grains (OR = 1.227), vegetables (OR = 1.944), and milk (OR = 2.26) significantly increased the adjusted odds ratio of SRH. However, smoking status was not associated with SRH scores. In conclusion, SRH is affected by the indices related to health but not smoking status in Korean adults. The development of a new indicator of the direct adverse effects of smoking at regular health check-ups might be required to modulate the SRH in smokers and a nutritional education should not include the possible attenuation of adverse effects of smoking by good nutrition.

This study analyzed the impact of area residential property values, an objective measure of socioeconomic status (SES), on self-rated health (SRH) in Seattle, Washington and Paris, France. This study brings forth a valuable comparison of SRH between cities that have contrasting urban forms, population compositions, residential segregation, food systems and transportation modes. The SOS (Seattle Obesity Study) was based on a representative sample of 1394 adult residents of Seattle and King County in the United States. The RECORD Study (Residential Environment and Coronary Heart Disease) was based on 7131 adult residents of Paris and its suburbs in France. Socio-demographics, SRH and body weights were obtained from telephone surveys (SOS) and in-person interviews (RECORD). All home addresses were geocoded using ArcGIS 9.3.1 (ESRI, Redlands, CA). Residential property values were obtained from tax records (Seattle) and from real estate sales (Paris). Binary logistic regression models were used to test the associations among demographic and SES variables and SRH. Higher area property values significantly associated with better SRH, adjusting for age, gender, individual education, incomes, and BMI. The associations were significant for both cities. A one-unit increase in body mass index (BMI) was more detrimental to SRH in Seattle than in Paris. In both cities, higher area residential property values were related to a significantly lower obesity risk and better SRH. Ranked residential property values can be useful for health and weight studies, including those involving social inequalities and cross-country comparisons.

Younger people with heart failure often experience poor self-rated health. Furthermore, poor self-rated health is associated with long-term sick leave and disability pension. Socio-demographic factors affect the ability to return to work. However, little is known about people on sick leave due to heart failure. The aim of this study was to investigate associations between self-rated health, mood, socio-demographic factors, sick leave compensation, encounters with healthcare professionals and social insurance officers and self-estimated ability to return to work, for people on sick leave due to heart failure. This population-based investigation had a cross-sectional design. Data were collected in Sweden in 2012 from two official registries and from a postal questionnaire. In total, 590 subjects, aged 23-67, responded (response rate 45.8%). Descriptive statistics, correlation analyses (Spearman bivariate analysis) and logistic regression analyses were used to investigate associations. Poor self-rated health was strongly associated with full sick leave compensation (OR = 4.1, p < .001). Compared self-rated health was moderately associated with low income (OR = .6, p = .003). Good self-rated health was strongly associated with positive encounters with healthcare professionals (OR = 3.0, p = .022) and to the impact of positive encounters with healthcare professionals on self-estimated ability to return to work (OR = 3.3, p < .001). People with heart failure are sicklisted for long periods of time and to a great extent receive disability pension. Not being able to work imposes reduced quality of life. Positive encounters with healthcare professionals and social insurance officers can be supportive when people with heart failure struggle to remain in working life.

We sought to examine the joint and independent contributions of working conditions and health-related behaviours in explaining social gradients in self-rated health (SRH). Nationally representative cross-sectional data from the Swiss Health Survey of 2007 were used for this study. Bi- and multivariate statistical analyses were carried out on a sample of 6950 adult employees of working age. We examined a comprehensive set of five health behaviours and lifestyle factors as well as twelve physical and psychosocial work factors as potential mediators of the relationship between social status and SRH. Analyses were stratified by sex and performed using two measures of social status, educational level and occupational position. Strong social gradients were found for SRH, but mainly in men whereas in women the associations were either not linear (educational level) or not statistically significant (occupational position). Social gradients were also found for most lifestyle and all physical and psychosocial work factors studied. These three groups of factors equally contributed to and largely accounted for the social gradients in SRH although not all of the individual factors turned out to be independent and significant risk factors for poor SRH. Such risk factors included physical inactivity and obesity, poor posture and no or low social support at work (both sexes), heavy smoking (men) and underweight, overweight, uniform arm or hand movements at work, monotonous work and job insecurity (women). In conclusion, social inequalities (or more precisely educational and occupational status differences) in SRH were more pronounced in men and can be attributed for the most part to a sedentary lifestyle and to a physically demanding and socially unsupportive and insecure work environment. Apart from this main finding and overall pattern, sex-specific risk profiles were observed with regard to SRH and need to be taken into consideration.

Objective Several studies indicate that ethnicity may be a strong predictor of poor self-rated health (SRH). The aims of the present study were to investigate whether there was an association between ethnicity and poor SRH in subjects with type 2 diabetes and to determine if the association remained after adjusting for possible confounders such as age, gender employment, marital status, and education. Design A cross-sectional study based on a patient population in the town of Södertälje. An unconditional logistic regression was performed to estimate the odds ratios (ORs) and 95% confidence intervals (95% CIs). Setting Four primary health care centers. Subjects A total of 354 individuals were included: Assyrian/Syrian-born (n = 173) and Swedish-born (n = 181). Results The odds ratio for rating poor SRH for Assyrian/Syrian subjects with type 2 diabetes was 4.5 times higher (95% CI = 2.7–7.5) than for Swedish patients in a crude model. After adjusting for possible confounders, unemployed/retired people had 5.4 times higher odds for reporting poor SRH than employees (OR = 5.4; 95% CI = 2.3–12.5). Women had 1.8 times higher odds (95% CI = 1.0–3.0) for reporting poor SRH than men. In the final model poor SRH among Assyrians/Syrians decreased but still remained significant (OR=3.7; 95% CI = 2.5–6.6). Conclusions The findings in this study are important for planning primary health care services. They highlight the crucial importance of being aware of the subjective health status of immigrants fleeing from war in the Middle East and resettling in Sweden. PMID:20608888

The recent housing crisis offers the opportunity to understand the effects of unique indicators of macroeconomic conditions on health. We linked data on the proportion of mortgage borrowers per US metropolitan-area who were at least 90 days delinquent on their payments with individual-level outcomes from a representative sample of 1,021,341 adults surveyed through the Behavioral Risk Factor Surveillance System (BRFSS) between 2003 and 2010. We estimated the effects of metropolitan-area mortgage delinquency on individual health behaviors, medical coverage, and health status, as well as whether effects varied by race/ethnicity. Results showed that increases in the metropolitan-area delinquency rate resulted in decreases in heavy alcohol consumption and increases in exercise and health insurance coverage. However, the delinquency rate was also associated with increases in smoking and obesity in some population groups, suggesting the housing crisis may have induced stress-related behavioral change. Overall, the effects of metropolitan-area mortgage delinquency on population health were relatively modest.

The Mormon church has long been seen as an unusual group in relation to its health practices. But its health traditions and practices go much further than the ban on tobacco, coffee, and alcohol for which it is so well known. Church teachings and influences pervade the entire Mormon existence. This paper briefly discusses these traditions, first by examining their roots in the teachings of its first two prophet/presidents, Joseph Smith and Brigham Young. Then, how these ideas have evolved into the church's current thought is examined; and finally, the church's responses to many modern-day health care issues are presented.
Background The lack of culturally adapted and validated instruments for child mental health and psychosocial support in low and middle-income countries is a barrier to assessing prevalence of mental health problems, evaluating interventions, and determining program cost-effectiveness. Alternative procedures are needed to validate instruments in these settings. Methods Six criteria are proposed to evaluate cross-cultural validity of child mental health instruments: (i) purpose of instrument, (ii) construct measured, (iii) contents of construct, (iv) local idioms employed, (v) structure of response sets, and (vi) comparison with other measurable phenomena. These criteria are applied to transcultural translation and alternative validation for the Depression Self-Rating Scale (DSRS) and Child PTSD Symptom Scale (CPSS) in Nepal, which recently suffered a decade of war including conscription of child soldiers and widespread displacement of youth. Transcultural translation was conducted with Nepali mental health professionals and six focus groups with children (n = 64) aged 11-15 years old. Because of the lack of child mental health professionals in Nepal, a psychosocial counselor performed an alternative validation procedure using psychosocial functioning as a criterion for intervention. The validation sample was 162 children (11-14 years old). The Kiddie-Schedule for Affective Disorders and Schizophrenia (K-SADS) and Global Assessment of Psychosocial Disability (GAPD) were used to derive indication for treatment as the external criterion. Results The instruments displayed moderate to good psychometric properties: DSRS (area under the curve (AUC) = 0.82, sensitivity = 0.71, specificity = 0.81, cutoff score ≥ 14); CPSS (AUC = 0.77, sensitivity = 0.68, specificity = 0.73, cutoff score ≥ 20). The DSRS items with significant discriminant validity were "having energy to complete daily activities" (DSRS.7), "feeling that life is not worth living" (DSRS.10), and "feeling

In this analysis we employed the International Health Behaviour Among School Aged Children (HBSC) 1998 data, comprising 8326 Irish children and 115,327 children in the International dataset, to examine influences on self reported health among young people. Factors were similar for both boys and girls and between countries. Daily smokers, those reporting intoxication at least once, those taking infrequent exercise and those reporting difficulty in making friends were all predictive of poor self-rated health in adjusted odds ratio models. Disposable means, as measured by the Family Affluence Score was also a significant predictor of self-rated health but not as influential as reported lifestyle. In a multi-level between country comparison of 15 OECD countries, individual health behaviours explained much, but not all of the variability in poor self reported health (0.26, SE 0.08), and of various ecological level indicators considered in the final model only % voting and % males with minimum 2nd level of male education in the population were influential factors, with between-country variations still not fully explained (0.10, SE 0.03).
Background Pelvic girdle pain (PGP) in pregnancy is distinct from pregnancy-related low back pain (PLBP). However, women with combined PLBP and PGP report more serious consequences in terms of health and function. PGP has been estimated to affect about half of pregnant women, where 25% experience serious pain and 8% experience severe disability. To date there are relatively few studies regarding persistent PLBP/PGP postpartum of more than 3 months, thus the main objective was to identify the prevalence of persistent PLBP and PGP as well as the differences over time in regard to pain status, self-rated health (SRH) and family situation at 12 months postpartum. Methods The study is a 12 month follow-up of a cohort of pregnant women developing PLBP and PGP during pregnancy, and who experienced persistent pain at 6 month follow-up after pregnancy. Women reporting PLBP/PGP (n = 639) during pregnancy were followed up with a second questionnaire at approximately six month after delivery. Women reporting recurrent or persistent LBP/PGP at the second questionnaire (n = 200) were sent a third questionnaire at 12 month postpartum. Results A total of 176 women responded to the questionnaire. Thirty-four women (19.3%) reported remission of LBP/PGP, whereas 65.3% (n = 115) and 15.3% (n = 27), reported recurrent LBP/PGP or continuous LBP/PGP, respectively. The time between base line and the 12 months follow-up was in actuality 14 months. Women with previous LBP before pregnancy had an increased odds ratio (OR) of reporting ‘recurrent pain’ (OR = 2.47) or ‘continuous pain’ (OR = 3.35) postpartum compared to women who reported ‘no pain’ at the follow-up. Women with ‘continuous pain’ reported statistically significant higher level of pain at all measure points (0, 6 and 12 months postpartum). Non-responders were found to report a statistically significant less positive scoring regarding relationship satisfaction compared to responders
Health-related quality of life in Huntington's disease patients: a comparison of proxy assessment and patient self-rating using the disease-specific Huntington's disease health-related quality of life questionnaire (HDQoL).
Hocaoglu, Mevhibe B; Gaffan, E A; Ho, Aileen K
Huntington's disease (HD) is a fatal, neurodegenerative disease for which there is no known cure. Proxy evaluation is relevant for HD as its manifestation might limit the ability of persons to report their health-related quality of life (HrQoL). This study explored patient-proxy ratings of HrQoL of persons at different stages of HD, and examined factors that may affect proxy ratings. A total of 105 patient-proxy pairs completed the Huntington's disease health-related quality of life questionnaire (HDQoL) and other established HrQoL measures (EQ-5D and SF-12v2). Proxy-patient agreement was assessed in terms of absolute level (mean ratings) and intraclass correlation. Proxies' ratings were at a similar level to patients' self-ratings on an overall Summary Score and on most of the six Specific Scales of the HDQoL. On the Specific Hopes and Worries Scale, proxies on average rated HrQoL as better than patients' self-ratings, while on both the Specific Cognitive Scale and Specific Physical and Functional Scale proxies tended to rate HrQoL more poorly than patients themselves. The patient's disease stage and mental wellbeing (SF-12 Mental Component scale) were the two factors that primarily affected proxy assessment. Proxy scores were strongly correlated with patients' self-ratings of HrQoL, on the Summary Scale and all Specific Scales. The patient-proxy correlation was lower for patients at moderate stages of HD compared to patients at early and advanced stages. The proxy report version of the HDQoL is a useful complementary tool to self-assessment, and a promising alternative when individual patients with advanced HD are unable to self-report.
Relationship of Self-Rated Health to Stroke Incidence and Mortality in Older Individuals with and without a History of Stroke: A Longitudinal Study of the MRC Cognitive Function and Ageing (CFAS) Population
Mavaddat, Nahal; van der Linde, Rianne; Parker, Richard; Savva, George; Kinmonth, Ann Louise; Brayne, Carol; Mant, Jonathan
Introduction Poor self-rated health (SRH) has been associated with increased risk of death and poor health outcomes even after adjusting for confounders. However its’ relationship with disease-specific mortality and morbidity has been less studied. SRH may also be particularly predictive of health outcomes in those with pre-existing conditions. We studied whether SRH predicts new stroke in older people who have never had a stroke, or a recurrence in those with a prior history of stroke. Methods MRC CFAS I is a multicentre cohort study of a population representative sample of people in their 65th year and older. A comprehensive interview at baseline included questions about presence of stroke, self-rated health and functional disability. Follow-up at 2 years included self-report of stroke and stroke death obtained from death certificates. Multiple logistical regression determined odds of stroke at 2 years adjusting for confounders including disability and health behaviours. Survival analysis was performed until June 2014 with follow-up for up to 13 years. Results 11,957 participants were included, of whom 11,181 (93.8%) had no history of stroke and 776 (6.2%) one or more previous strokes. Fewer with no history of stroke reported poor SRH than those with stroke (5 versus 21%). In those with no history of stroke, poor self-rated health predicted stroke incidence (OR 1.5 (1.1–1.9)), but not stroke mortality (OR 1.2 (0.8–1.9)) at 2 years nor for up to 13 years (OR 1.2(0.9–1.7)). In those with a history of stroke, self-rated health did not predict stroke incidence (OR 0.9(0.6–1.4)), stroke mortality (OR 1.1(0.5–2.5)), or survival (OR 1.1(0.6–2.1)). Conclusions Poor self-rated health predicts risk of stroke at 2 years but not stroke mortality among the older population without a previous history of stroke. SRH may be helpful in predicting who may be at risk of developing a stroke in the near future. PMID:26928666

The lack of social support in elderly populations incurs real societal costs and can lead to their poor health. The aim of this study is to investigate the self-rated health (SRH) and social support among older people as well as its associated factors.We conducted a cross-sectional study among 312 urban community-dwelling elderly aged 65 to 90 years in Tainan Taiwan and Fuzhou Fujian Province from March 2012 to October 2012. A Spearson correlation test, independent t test, a Pearson χ test, a linear regression analysis, and a multiple-level model were performed to analyze the results.The participants identified children as the most important source of objective and subjective support, followed by spouse and relatives. Tainan's elderly received more daily life assistance and emotional support, showed stronger awareness of the need to seek help, and maintained a higher frequency of social interactions compared with the elderly in Fuzhou. The mean objective support, subjective support, and support utilization scores as well as the overall social support among Tainan's elderly were significantly high compared with the scores among Fuzhou's elderly. Further, Tainan's elderly rated better SRH than Fuzhou's elderly. Correlation analysis showed that social support was significantly correlated with city, age, living conditions, marital status, and SRH. Multiple linear regression analysis, with social support as a dependent variable, retained the following independent predictors in the final regression model: city (4.792, 95% confidence interval [CI]: 3.068-6.516, P = 0.000), age (-0.805, 95% CI: -1.394 to -0.135, P = 0.013), marital status (-1.260, 95% CI: -1.891 to -0.629, P = 0.000), living conditions (4.069, 95% CI: 3.022-5.116, P = 0.000), and SRH -1.941, 95% CI: -3.194 to -0.688, P = 0.003). The multiple-level model showed that city would impact older people's social support (χ = 5.103, P < 0.001). Marital status (-2.133, 95% CI: -2.768 to -1.499, P = 0

Sexual health is an evolving paradigm that integrates a positive approach to sexuality with existing public health policy and practice for reducing the burdens of sexually transmitted infections, including those due to HIV. The sexual health paradigm rests in commitment to sexual rights, sexual knowledge, sexual choice, and sexual pleasure, as well as key elements of sexuality addressed by sexual desire, sexual arousal, and sexual function, and sexual behaviors. The sexual health paradigm offers new approaches to supporting general health and well being while reducing the burdens of sexual diseases and their consequences.
Building a new life in Australia: an analysis of the first wave of the longitudinal study of humanitarian migrants in Australia to assess the association between social integration and self-rated health
Chen, Wen; Ling, Li; Renzaho, Andre M N
Objectives To assess the relationship between social integration and physical and mental health among humanitarian migrants (HMs) in Australia. Design, setting and participants We used the recently released first wave of data from the 2013 ‘Building a New Life in Australia’ survey, which is an ongoing nationwide longitudinal study. A total of 2399 HMs participated in the survey. Main outcome measures Self-rated physical health was measured using four items selected from the SF-36 which is a generic measure of health status. The 6-item Kessler Screening Scale for Psychological Distress (K6) was used to measure mental health. Social integration was measured using four dimensions: economic integration, acculturation, social capital and self-identity. Results More than half (63%), 47% and 49% of participants self-rated well on the general health, physical function and role-physical dimensions, respectively and 46% reported not having any bodily pain. Seventeen per cent of participants had a serious mental illness. There was a positive relationship between social integration and physical and mental health. That is, factors associated with better health included less financial hardship (economic integration dimension), better English proficiency and self-sufficiency (acculturation dimension), having the capacity to communicate with locals, having friends from different ethnic/religious groups and attending a place of worship weekly or more often (social capital dimension) and feeling welcomed and having a strong sense of belonging in Australia (self-identity dimension). Conclusions Using a more comprehensive framework of social integration, we found that greater social integration was associated with better physical and mental health outcomes among HMs. Social integration should be embedded in HMs' resettlement programmes in order to reduce migration-related health inequities.

Community Health Information Network (CHIN) developments have slowed, due to the chaotic change in the health care system and stakeholders' attendant short-sighted focus. CHINs are a long-term investment that is necessary for the health care system's evolution to maturity. Several arenas of essential CHIN activity are given that would be characteristic of a mature, goal-directed health care system Lack of enterprise-wide computer-based patient record systems is a major barrier. Even in the short term, however, trends and incentives exist that are likely to push stakeholders toward CHIN development. Some of these trends include changes in organizational structure and political pressures. Practical incentives include the need for stakeholder cooperation to achieve healthy communities, the prospects for telemedicine, and the demand for greater quality assurance. PMID:8947737
Do perceived job insecurity and annoyance due to air and noise pollution predict incident self-rated poor health? A prospective analysis of independent and joint associations using a German national representative cohort study
Riedel, Natalie; Loerbroks, Adrian; Bolte, Gabriele; Li, Jian
Background Current economic and social change has contributed to increasing job insecurity and traffic-related pollution in residential areas. Both job insecurity and exposure to noise and air pollution are known determinants of population health and can concur in peoples' lives. This may hold true particularly for socially disadvantaged subpopulations. Nevertheless, the potential independent and joint links of those exposures to health have been rarely examined so far. We aimed to contribute to the scarce body of evidence. Methods Information on perceived job insecurity and exposures to noise and air pollution as expressed by annoyance as well as on self-rated health were gathered from 2 waves of the population-based German Socio-Economic Panel (2009 and 2011, N=6544). We performed multivariable Poisson regression to examine the independent and joint risk of poor health in 2011 by perceived job insecurity and annoyance due to noise and air pollution in 2009. Results After the 2-year follow-up in 2011, 571 (8.7%) participants rated their health as poor. The risk of reporting incident poor health was increased by roughly 40% in employees reporting high versus low perceived job insecurity and annoyance due to noise and air pollution, respectively. This risk increased when both exposures were present at higher levels (risk ratio=1.95 (1.49 to 2.55)). Conclusions Work-related and environmental exposures may accumulate and have a joint health impact. Elaboration on the link between occupational and residential exposures is warranted in the light of their concurrence and their implications for health inequities. PMID:28115332

This study investigates the relation between overweight/obesity and self-rated health (SRH), and whether this relation varies by social factors. Data was taken from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS, baseline 2003‒2006). For the definition of overweight and obesity, body mass index was calculated based on standardized height and weight measurements. SRH of adolescents (n = 6813, 11‒17 years) was raised with the question: "How would you describe your health in general?" The response categories were "very good", "good", "fair", "poor", and "very poor". We dichotomized these responses into: "very good/good" vs. "fair/poor/very poor". Socio-economic status (SES) in the family of origin and adolescents' school type were analyzed as modifying factors. Prevalence and age-adjusted odds ratios with 95% confidence intervals were calculated by binary logistic regression models. We found that overweight and obese boys and obese girls reported fair to very poor SRH more often than their normal weight peers, and that these differences were more apparent in early than late adolescence. In addition, the relation between obesity and SRH was similarly strong in all sub-groups, but there was seldom a relation between overweight and SRH. In summary, the results show that obesity is linked to poor SRH regardless of SES and school type, while the relation between overweight and SRH varies by social factors among adolescents.

There has been growing tension at the intersection of health and economic policymaking as global governance has increased across sectors. This tension has been particularly evident between tobacco control and trade policy, as the international norms that frame them – particularly the Framework Convention on Tobacco Control and the World Trade Organization (WTO) – have continued to institutionalize. Using five case studies of major tobacco-related trade disputes from the principal multilateral system of trade governance – the WTO/General Agreement on Tariffs and Trade – we trace the evolution of these interacting norms over nearly 25 years. Our analytic framework particularly focuses on the actors that advance, defend and challenge these norms. We find that an increasingly broad network, which includes governments, intergovernmental organizations, non-governmental organizations and members of the epistemic community, is playing a more active role in seeking to resolve these tensions. Moreover, key economic actors are beginning to incorporate health more actively in their messaging and activities. We also demonstrate that the most recent resonant messages reflect a more nuanced integration of the two norms. The tobacco control example has direct relevance to related policy areas, including environment, safety, access to medicines, diet, and alcohol. PMID:24603086

In this study, we investigated whether self-rated health (SRH) can be predicted by in-work poverty and how between-persons and within-person differences in the poverty status of people who are working contribute to this relationship. We used a logistic random-effects model designed to test within-person and between-persons differences with data from a nationally representative German sample with 19 waves of data collection (1995-2013) to estimate effects of between-persons and within-person differences in working poverty status on poor SRH. Interactions by age and sex were tested, and models controlled for sociodemographic, socioeconomic, and work-related characteristics. We found significant differences in SRH between individuals with different working poverty status but no evidence that within-person differences in working poverty status are associated with poor SRH. The association between in-work poverty and SRH was significantly stronger for women but did not differ significantly by age. All findings were robust when including sociodemographic, socioeconomic, and working characteristics. In this sample of German adults, we found a polarization of poor SRH between the working nonpoor and the working poor but no causal association of within-person differences in working poverty status with SRH.

Background Self-rated health (SRH) has strong predictive value for mortality in different contexts and cultures, but there is inconsistent evidence on ethnoracial disparities in SRH in Latin America, possibly due to the complexity surrounding ethnoracial self-classification. Materials/Methods We used 370,539 Single Nucleotide Polymorphisms (SNPs) to examine the association between individual genomic proportions of African, European and Native American ancestry, and ethnoracial self-classification, with baseline and 10-year SRH trajectories in 1,311 community dwelling older Brazilians. We also examined whether genomic ancestry and ethnoracial self-classification affect the predictive value of SRH for subsequent mortality. Results European ancestry predominated among participants, followed by African and Native American (median = 84.0%, 9.6% and 5.3%, respectively); the prevalence of Non-White (Mixed and Black) was 39.8%. Persons at higher levels of African and Native American genomic ancestry, and those self-identified as Non-White, were more likely to report poor health than other groups, even after controlling for socioeconomic conditions and an array of self-reported and objective physical health measures. Increased risks for mortality associated with worse SRH trajectories were strong and remarkably similar (hazard ratio ~3) across all genomic ancestry and ethno-racial groups. Conclusions Our results demonstrated for the first time that higher levels of African and Native American genomic ancestry—and the inverse for European ancestry—were strongly correlated with worse SRH in a Latin American admixed population. Both genomic ancestry and ethnoracial self-classification did not modify the strong association between baseline SRH or SRH trajectory, and subsequent mortality. PMID:26680774

Until recently, most studies on social capital and health have been cross-sectional making it difficult to draw causal conclusions. This longitudinal study used data from 33,621 individuals (15,822 men and 17,799 women) from the Västerbotten Intervention Program, to analyse how changes in access to individual social capital influence self-rated health (SRH) over time. Two forms of structural social capital, i.e. informal socializing and social participation, were measured. Age, sex, education, marital status, smoking, snuff, physical activity, alcohol consumption, high blood pressure, and body mass index were analysed as potential confounders. The association between changes in access to structural social capital and SRH in the follow-up was adjusted for SRH at baseline, as well as for changes in the socio-demographic and health-risk variables over time. The results support that changes in access to structural social capital over time impact on SRH. Remaining with no/low level of informal socializing over time increased the odds ratio for poor SRH for both men and women (OR of 1.45; 95%CI = 1.22-1.73 among men and OR of 1.56; 95%CI = 1.33-1.84 among women). Remaining with no/low levels of social participation was also detrimental to SRH in men and women (OR 1.14; 95%CI = 1.03-1.26 among men and OR 1.18; 95%CI = 1.08-1.29 among women). A decrease in informal socializing over time was associated with poor SRH for women and men (OR of 1.35; 95%CI = 1.16-1.58 among men and OR of 1.57; 95%CI = 1.36-1.82 among women). A loss of social participation had a negative effect on SRH among men and women (OR of 1.16; 95%CI = 1.03-1.30 among men and OR of 1.15; 95%CI = 1.04-1.27 among women). Gaining access to social participation was harmful for SRH for women (OR 1.17; 95%CI = 1.05-1.31). Structural social capital has complex and gendered effects on SRH and interventions aiming to use social capital for health promotion purposes require an awareness of its gendered nature.

The landscape of foodborne infections is in flux. New pathogens emerge, established pathogens may acquire new characteristics and appear in unexpected food vehicles, while many existing problems remain unsolved. Consumers want more fresh foods year round, populations age and migrate, and the technologies and trade practices that produce foods change. Protecting the public health and minimizing the burden of foodborne illness mean expecting the unexpected, and being prepared to understand it when it occurs, so that prevention can be improved. Public health surveillance is also constantly evolving, as new diseases emerge and are judged worthy of notification, as new diagnostic tests change the ease and specificity of routine diagnosis and as social interest in particular issues waxes and wanes. Accurate health information, including reliable estimates of the burden of foodborne disease, can improve foodborne disease prevention, foster global health security, promote economic growth and development and strengthen evidence-based policy making.

The statist approach, which is primarily security-focused, seeks to link health initiatives to a foreign or defence policy remit. The globalist approach, in contrast, seeks to advance health not because of its intrinsic security value but because it advances the well-being and rights of individuals. This article charts the evolution of these approaches and demonstrates why both have the potential to shape our understanding of the evolving global health agenda. It examines how the statist and globalist perspectives have helped shape contemporary initiatives in global health governance and suggests that there is evidence of an emerging convergence between the two perspectives. This convergence is particularly clear in the articulation of a number of UN initiatives in this area - especially the One World, One Health Strategic Framework and the Oslo Ministerial Declaration (2007) which inspired the first UN General Assembly resolution on global health and foreign policy in 2009 and the UN Secretary-General's note "Global health and foreign policy: strategic opportunities and challenges". What remains to be seen is whether this convergence will deliver on securing states' interest long enough to promote the interests of the individuals who require global efforts to deliver local health improvements.

Early environmental justice studies were exposure-oriented, lacked an integrated approach, and did not address the health impact of environmental inequalities. A coherent conceptual framework, needed to understand and tackle environmental inequalities and the related health effects, was lacking. We analyzed the more recent environmental justice literature to find out how conceptual insights have evolved. The conceptual framework of the WHO Commission on Social Determinants of Health (CSDH) was analyzed for additional explanations for environmental inequalities and the related health effects. This paper points out that recent environmental justice studies have broadened their scope by incorporating a broader set of physical and social environmental indicators, and by focusing on different geographic levels and on health impacts of environmental inequalities. The CSDH framework provided additional elements such as the role of structural determinants, the role of health-related behavior in relation to the physical and social environment, access to health care, as well as the life course perspective. Incorporating elements of the CSDH framework into existing environmental justice concepts, and performing more empirical research on the interactions between the different determinants at different geographical levels would further improve our understanding of environmental inequalities and their health effects and offer new opportunities for policy action.

This article summarizes personal views on the rapidly evolving field of functional health assessment and comments on their implications for advances in assessment methods used in rehabilitation medicine. Topics of strategic importance included (1). a new formulation of the structure of health status designed to distinguish role participation from the physical and mental components of health for purposes of international studies; (2). applications of item response theory that offer advantages in constructing better functional health measures and cross-calibrating their underlying metrics; (3). computerized dynamic assessment technology, well proven in education and psychology, which may lead to more practical assessments and more precise score estimates across a wide range of functional health levels; and (4). intellectual property issues involved in standardizing and promoting readily available assessment tools, ensuring their scientific validity, and achieving the best possible partnership between the scientific community and those developing commercial applications. Promising results from preliminary attempts to standardize and improve the metrics of functional health assessment constitute grounds for optimism regarding their potential usefulness in rehabilitation medicine. Someday, all tools used to measure each functional health concept, including the best single-item measure and the most precise computerized dynamic health assessment, will be scored on the same metric and their results will be directly comparable. To achieve this goal in rehabilitation medicine, we have much work to do.

We report on the development, reliability, and validity of the Altman Self-Rating Mania Scale (ASRM). The ASRM was completed during medication washout and after treatment by 22 schizophrenic, 13 schizoaffective, 36 depressed, and 34 manic patients. The Clinician-Administered Rating Scale for Mania (CARS-M) and Mania Rating Scale (MRS) were completed at the same time to measure concurrent validity. Test-retest reliability was assessed separately on 20 depressed and 10 manic patients who completed the ASRM twice during washout. Principal components analysis of ASRM items revealed three factors: mania, psychotic symptoms, and irritability. Baseline mania subscale scores were significantly higher for manic patients compared to all other diagnostic groups. Manic patients had significantly decreased posttreatment scores for all three subscales. ASRM mania subscale scores were significantly correlated with MRS total scores (r = .718) and CARS-M mania subscale scores (r = .766). Test-retest reliability for the ASRM was significant for all three subscales. Significant differences in severity levels were found for some symptoms between patient ratings on the ASRM and clinician ratings on the CARS-M. Mania subscale scores of greater than 5 on the ASRM resulted in values of 85.5% for sensitivity and 87.3% for specificity. Advantages of the ASRM over other self-rating mania scales are discussed.

This paper provides a theoretical review of self-rated competences questionnaires. This topic is influenced by the ongoing world-wide reform of higher education, which has led to a focus on the learner outcomes of higher education. Consequently, questionnaires on self-rated competences have increasingly been employed. However, self-ratings are…
A war hospital installed close to the front by a group of young Bangladeshi doctors during the 1971 war of liberation from Pakistan was the origin of the new "Gonoshasthaya Kendra" (GK), or people's health center, 40 km north of Dhaka in Savar. At the new center, as in the hospital, trained paramedics furnish basic health care for the population. The center at Savar was applying the principles of primary health care 6 years before they were recognized at the Alma Ata conference. Today, GK has integrated programs to fight poverty into its health activities, with educational, nutrition, and employment programs. The paramedics have a long training course, working under the supervision of a senior paramedic for a year and receiving theoretical training in the evenings. They do not become senior paramedics for several years. The work of the paramedics is oriented toward health education, prevention, and demoepidemiologic surveillance and registration. Each paramedic is responsible for 2 or 3 villages with about 3 thousand inhabitants. The paramedics visit and motivate the population, register births and deaths, identify and care for pregnant women, and vaccinate children and pregnant women. They provide health and nutrition education, treat diarrhea and instruct mothers in use of oral rehydration therapy, and provide family planning information and supplies. Persons in need are referred to "clinic days" held regularly in the larger villages. The paramedics maintain records for each family which allow calculation of vital rates and epidemiologic data. In the region of Savar served by the paramedics, the rates of general mortality and infant mortality are 12/1000 and 85/1000 respectively, vs. 17 and 124/1000 in Bangladesh as a whole. The GK has a new goal of reducing infant mortality to 60/1000. The paramedics have been taught to recognize 2 new symptoms, convulsions and respiratory distress, and to refer infants showing these symptoms to doctors. The GK doctors believe

Objective An investigation into evolving food retail systems in Thailand Design Rapid assessment procedures based on qualitative research methods such as interviews, focus groups discussions and site visits Setting Seven freshmarkets located in the four main regions of Thailand Subjects Managers, food specialists, vendors and shoppers from seven freshmarkets who participated in interviews and focus group discussions. Results Freshmarkets are under economic pressure and are declining in number. They are attempting to resist the competition from supermarkets by improving convenience, food diversity, quality and safety. Conclusions Obesity has increased in Thailand at the same time as rapid growth of modern food retail formats has occurred. As freshmarkets are overtaken by supermarkets there is a likely loss of fresh, healthy, affordable food for poorer Thais, and a diminution of regional culinary culture, women’s jobs and social capital with implications for the health and nutrition transition in Thailand.

Prior to the advent of the coronary care unit (CCU), patients having an acute myocardial infarction (AMI) were managed on the general medicine wards with reported mortality rates of greater than 30%. The first CCUs are believed to be responsible for reducing mortality attributed to AMI by as much as 40%. This drastic improvement can be attributed to both advances in medical technology and in the process of health care delivery. Evolving considerably since the 1960s, the CCU is now more appropriately labeled as a cardiac intensive care unit (CICU) and represents a comprehensive system designed for the care of patients with an array of advanced cardiovascular disease, an entity that reaches far beyond its early association with AMI. Grouping of patients by diagnosis to a common physical space, dedicated teams of health care providers, as well as the development and implementation of evidence-based treatment algorithms have resulted in the delivery of safer, more efficient care, and most importantly better patient outcomes. The CICU serves as a platform for an integrated, team-based patient care delivery system that addresses a broad spectrum of patient needs. Lessons learned from this model can be broadly applied to address the urgent need to improve outcomes and efficiency in a variety of health care settings.
Examining Associations between Self-Rated Health and Proficiency in Literacy and Numeracy among Immigrants and U.S.-Born Adults: Evidence from the Program for the International Assessment of Adult Competencies (PIAAC).
Prins, Esther; Monnat, Shannon
This paper uses data from the Program for the International Assessment of Adult Competencies (PIAAC) to analyze the relationship between self-reported health (SRH) and literacy and numeracy proficiency for immigrants compared to U.S.-born respondents and for Hispanic versus Asian immigrants. The research questions were: (1) Are literacy and numeracy scores associated with adults' SRH? (2) Are associations between SRH and literacy and numeracy proficiency moderated by immigrant status? (3) Among immigrants, are literacy and numeracy scores more strongly associated with SRH for Hispanics versus Asians? Immigrants had significantly lower literacy and numeracy scores, yet reported better health than U.S.-born respondents. Ordinal logistic regression analyses showed that literacy and numeracy were both positively related to SRH for immigrants and U.S.-born adults, and should therefore be viewed as part of the growing evidence that literacy is an independent and significant social determinant of health. Second, U.S.-born and immigrant adults accrued similarly positive health benefits from stronger literacy and numeracy skills. Third, although Hispanic immigrants were more disadvantaged than Asian immigrants on almost all socioeconomic characteristics and had significantly lower literacy and numeracy scores and worse SRH than Asian immigrants, both Hispanic and Asian immigrants experienced similar positive health returns from literacy and numeracy proficiency. These findings underscore the potential health benefits of providing adult basic education instruction, particularly for immigrants with the least formal schooling and fewest socioeconomic resources.

The Children's Health Insurance Program (CHIP) Reauthorization Act (CHIPRA) reauthorized CHIP through federal fiscal year 2019 and, together with provisions in the Affordable Care Act, federal funding for the program was extended through federal fiscal year 2015. Congressional action is required or federal funding for the program will end in September 2015. This supplement to Academic Pediatrics is intended to inform discussions about CHIP's future. Most of the new research presented comes from a large evaluation of CHIP mandated by Congress in the CHIPRA. Since CHIP started in 1997, millions of lower-income children have secured health insurance coverage and needed care, reducing the financial burdens and stress on their families. States made substantial progress in simplifying enrollment and retention. When implemented optimally, Express Lane Eligibility has the potential to help cover more of the millions of eligible children who remain uninsured. Children move frequently between Medicaid and CHIP, and many experienced a gap in coverage with this transition. CHIP enrollees had good access to care. For nearly every health care access, use, care, and cost measure examined, CHIP enrollees fared better than uninsured children. Access in CHIP was similar to private coverage for most measures, but financial burdens were substantially lower and access to weekend and nighttime care was not as good. The Affordable Care Act coverage options have the potential to reduce uninsured rates among children, but complex transition issues must first be resolved to ensure families have access to affordable coverage, leading many stakeholders to recommend funding for CHIP be continued.

Recent federal health care legislation contains explicit and implicit drivers for medical-dental collaboration. These laws implicitly promote health care evolution through value-based financing, "big data" and health information technology, increased number of care providers and a more holistic approach. Additional changes--practice aggregation, consumerism and population health perspectives--may also influence dental care. While dentistry will likely lag behind medicine toward value-based and accountable care organizations, dentists will be affected by changing consumer expectations.
The purpose of this study is to develop and test a conceptual model that assesses the following theoretical linkages: (1) people who go to church more often tend to receive more spiritual support from fellow church members (i.e., encouragement to adopt religious teachings and principles); (2) individuals who get more frequent spiritual support are…
At least 1.5 million preventable injuries because of adverse drug events occur in the United States each year, according to an Institute of Medicine report. IOM and other organizations at the forefront of health care improvement emphasize that stronger partnerships between patients, their families, and health care providers are necessary to make health care safer. Health educators possess a skill set and an ethical framework that effectively equip them to advance patient and family-centered care and contribute in other significant ways to a safer health care system. Health educators in clinical settings are playing varied and significant roles in advancing patient safety. They are removing barriers to clear communication and forging partnerships between patients, their families, and staff. Health educators are leading patient safety culture change within their institutions and contributing to the shift from provider-centric to patient-centric systems. To expand their impact in improving patient safety, health educators in clinical settings are participating in public awareness campaigns. In seeking to enhance patient safety, health educators face a number of challenges. To successfully manage those, health educators must expand their knowledge, broaden connections, and engage patients and families in meaningful ways.

The current state of health insurance coverage in the United States is deteriorating. Historically, efforts to address access at the federal level have met with insurmountable opposition. This article describes a model utilizing the Partnership Approach to Community Health Improvement to engage communities in developing creative ways of addressing local health issues, discusses the policy implications of such a model, and explores ethical issues inherent in the discussion of universal access. An argument is presented for a national dialogue seeking societal agreement to approach access and health from a perspective of solidarity.

Since the University of Chicago Health Management program was first initiated in 1932, programs and health delivery organizations have dealt with the issue of how to best provide a meaningful transition from academia to entry-level management. Today, new challenges face the same old questions: New federal legislation and increased demand for a finite supply of services cause increased revenue and expense pressures and result in the need for a higher performance level by a well-coordinated management team. In addressing these challenges, mentoring is an essential requirement for survival and success in health services. The long-term success of future practitioners will require both an understanding and incorporation of mentoring in their skill set. The University of Virginia Medical Center recently sponsored a health management education summit to examine the role of mentoring in health services administration education. Leading the program were John Westerman, former interim president of Association of University Programs in Healthcare Administration and chief executive officer emeritus of the University of Minnesota Health System, and R. Edward Howell, chief executive officer of the University of Virginia Medical Center. Summit participants included individuals who had completed administrative fellowship training programs. What follows is a review of the discussions during the summit, including a valuation of the health services fellowship as a learning experience as well as structure and essential elements of administrative mentoring programs.

Extensive research has demonstrated a relationship between socioeconomic factors and health among older adults, yet fewer studies have explored this relationship with older immigrants. This study aims to examine the influence of employment and self-rated economic condition on the subjective well-being of older Korean immigrants in the United States. Data were drawn from a cross-sectional study of 205 older Korean immigrants, aged 65 to 90, in Los Angeles County. Hierarchical regression was employed to explore the independent and interactive effects of employment status and self-rated economic condition. The study found that employment and self-rated economic status were positively associated with subjective well-being. Also, the interaction between employment and self-rated economic status was significantly associated with higher levels of subjective well-being, such that the influence of self-rated economic condition was stronger for unemployed older Korean immigrants compared with those who were employed. This population-based study provides empirical evidence that employment and self-rated economic condition are directly associated with subjective well-being for older Korean immigrants.

Global health spending share of low/middle income countries continues its long-term growth. BRICS nations remain to be major drivers of such change since 1990s. Governmental, private and out-of-pocket health expenditures were analyzed based on WHO sources. Medium-term projections of national health spending to 2025 were provided based on macroeconomic budgetary excess growth model. In terms of per capita spending Russia was highest in 2013. India's health expenditure did not match overall economic growth and fell to slightly less than 4% of GDP. Up to 2025 China will achieve highest excess growth rate of 2% and increase its GDP% spent on health care from 5.4% in 2012 to 6.6% in 2025. Russia's spending will remain highest among BRICS in absolute per capita terms reaching net gain from $1523 PPP in 2012 to $2214 PPP in 2025. In spite of BRICS' diversity, all countries were able to significantly increase their investments in health care. The major setback was bold rise in out-of-pocket spending. Most of BRICS' growing share of global medical spending was heavily attributable to the overachievement of People's Republic of China. Such trend is highly likely to continue beyond 2025.

As Latin American countries seek to guarantee sexual and reproductive health and rights, opponents of women's rights and reproductive choice have become more strident in their opposition, and are increasingly claiming conscientious objection to providing these services. Conscientious objection must be seen in the context of the rights and interests at stake, including women's health needs and right to self-determination. An analysis of law and policy on conscientious objection in Peru, Mexico and Chile shows that it is being used to erode women's rights, especially where it is construed to have no limits, as in Peru. Conscientious objection must be distinguished from politically-motivated attempts to undermine the law; otherwise, the still fragile re-democratisation processes underway in Latin America may be placed at risk. True conscientious objection requires that a balance be struck between the rights of the objector and the health rights of patients, in this case women. Health care providers are entitled to their beliefs and to have those beliefs accommodated, but it is neither viable nor ethically acceptable for conscientious objectors to exercise this right without regard for the right to health care of others, or for policy and services to be rendered ineffectual because of individual objectors.

Objective: The authors' goal was to assess changes in the role of librarians in informatics education from 2004 to 2013. This is a follow-up to “Metropolis Redux: The Unique Importance of Library Skills in Informatics,” a 2004 survey of informatics programs. Methods: An electronic survey was conducted in January 2013 and sent to librarians via the MEDLIB-L email discussion list, the library section of the American Association of Colleges of Pharmacy, the Medical Informatics Section of the Medical Library Association, the Information Technology Interest Group of the Association of College and Research Libraries/New England Region, and various library directors across the country. Results: Librarians from fifty-five institutions responded to the survey. Of these respondents, thirty-four included librarians in nonlibrary aspects of informatics training. Fifteen institutions have librarians participating in leadership positions in their informatics programs. Compared to the earlier survey, the role of librarians has evolved. Conclusions: Librarians possess skills that enable them to participate in informatics programs beyond a narrow library focus. Librarians currently perform significant leadership roles in informatics education. There are opportunities for librarian interdisciplinary collaboration in informatics programs. Implications: Informatics is much more than the study of technology. The information skills that librarians bring to the table enrich and broaden the study of informatics in addition to adding value to the library profession itself. PMID:25552939

The twenty-first century will provide exciting challenges for life and health sciences librarians that will force us to redefine our position in the world of information. This rapidly changing environment influences the profession in a variety of ways including whom we serve and through what service, how and where we practice librarianship, and even the very composition of the profession itself. We must look at the changes in society and make the appropriate reciprocal changes in how we educate future librarians, how we market the profession, and how we develop the profession as a whole. We, as life and health sciences librarians, need to meet these challenges head on in order to continue the evolution of the profession well into the twenty-first century. PMID:9681173

History tells us of the overwhelming destructive influence of exotic culture, politics and knowledge forms upon the worldview and wellbeing of Indigenous Australians. The power of dominant culture to oppress, control and dominate traditional Indigenous ways of knowing and being has been identified as a being a crucial influence on the health status, future hopes and aspirations of Indigenous Australians. Fundamental to this assertion is that the alienating effect of the belief in and application of the scientific method in relation to learning and knowing is a phenomenon that is incompatible with the law and cultural ways of traditional Indigenous people. The establishment of the Centre of Clinical Research Excellence (CCRE) is predicated upon and responds to a deep need in our community today to synthesise the ideological and epistemological premises of an increasing range of cultures and world views. It recognises that clinical research, for example, is important to the health of Aboriginal and Torres Strait Islander peoples, but also that the way such research is designed and carried out is also crucial to its potential to effect change in and improve the state of Indigenous health in Australia. This paper examines knowledge principles and processes associated with research in Indigenous communities, explores emerging research trends in science and proposes an epistemological framework for synthesis of traditional approaches with those of the scientific paradigm.

The organizational structures of academic health centers (AHCs) vary widely, but they all exist along a continuum of integration--that is, the degree to which the academic and clinical missions operate under a single administrative and governance structure. This author provides a brief overview of the topic of AHC integration, including the pros and cons of more integrated or less integrated models. He then traces the evolution of the University of Florida (UF) Health Science Center, which was created in the 1950s as a fully integrated AHC and which now operates under a more distributed management and governance model. Starting as a completely integrated AHC, UF's Health Science Center reached a time of maximal nonintegration (or dys-integration) in the late 1990s and at the beginning of this decade. Circumstances are now pushing the expanding clinical and academic enterprises to be more together as they face the challenges of market competition, federal research budget constraints, and reengineering clinical operations to reduce costs, enhance access, and improve quality and patient safety. Although formal organizational integration may not be possible or appropriate for any number of legal or political reasons, the author suggests that AHCs should strive for "functional integration" to be successful in the current turbulent environment.

Why is strategic positioning so important to health care organizations struggling in a managed care environment and what are the sources of value? In Part 1 of this article, entitled "The Sources of Value under Managed Care," the authors presented four sources of value relative to the evolution of the market from fee-for-service to managed care. These value sources are: (1) assets, (2) price/performance, (3) distribution, and, ultimately, (4) capabilities and brand equity. In this article, the authors further elaborate on the sources of value as the market moves beyond the historical fee-for-service position to a managed care marketplace. Part 2 presents the marketing and financial challenges to organizational positioning and performance across the four stages of managed care.

Although self-rated wellbeing is an indicator of health status, it has been receiving little attention; its relationship with physical activity among adults remains inconclusive. The purpose of this study was to analyse the relationship between physical activity and several dimensions of self-rated wellbeing in European adults. This cross-sectional study was based on data from the European Social Survey round 6, 2012, comprising 40,600 European adults (18,418 men, 22,186 women) from 27 countries, with mean age 42.1±13.3. Meeting physical activity guidelines was assessed using World Health Organization criteria. Six dimensions of the self-rated wellbeing were assessed (evaluative wellbeing, emotional wellbeing, functioning, vitality, community wellbeing, supportive wellbeing). Men and women who attained physical activity recommended levels had better evaluative wellbeing (men, p=0.009; women, p<0.001), emotional wellbeing (men, p<0.001; women, p<0.001), functioning (men, p<0.001; women, p<0.001), vitality (men, p<0.001; women, p<0.001), supportive relationships (men, p<0.001; women, p<0.001), and wellbeing total score (men, p<0.001; women, p<0.001). Physical activity frequency was linearly associated with self-rated wellbeing in the 6 dimensions as well as the wellbeing total score (p<0.001). Attaining recommended physical activity levels is related to better self-rated wellbeing, and more frequent physical activity is linearly associated with better self-rated wellbeing in its 6 dimensions.

Although often discussed, there is a lack of empirical research on the role of leadership in the management and delivery of health services. The implementation leadership scale (ILS) assesses the degree to which leaders are knowledgeable, proactive, perseverant, and supportive during evidence-based practice (EBP) implementation. The purpose of this study was to examine the psychometric properties of the ILS for leaders' self-ratings using a sample of mental health clinic supervisors (N = 119). Supervisors (i.e., leaders) completed surveys including self-ratings of their implementation leadership. Confirmatory factor analysis, reliability, and validity of the ILS were evaluated. The ILS factor structure was supported in the sample of supervisors. Results demonstrated internal consistency reliability and validity. Cronbach alpha's ranged from 0.92 to 0.96 for the ILS subscales and 0.95 for the ILS overall scale. The factor structure replication and reliability of the ILS in a sample of supervisors demonstrates its applicability with employees across organizational levels.

Effective communication is a vital component of nursing care, however, nurses often lack the skills to communicate with patients, carers and other health care professionals. Communication skills training programs are frequently used to develop these skills. However, there is a paucity of data on how best to evaluate such courses. The aim of the current study was to evaluate the relationship between student self rating of their own ability and their satisfaction with a nurse training course as compared with an objective measure of communication skills. 209 first year nursing students completed a communication skills program. Both qualitative and quantitative data were collected and associations between measures were investigated. Paired samples t-tests showed significant improvement in self-rated ability over the course of the program. Students generally were very satisfied with the course which was reflected in both qualitative and quantitative measures. However, neither self-rated ability nor satisfaction was significantly correlated with the objective measure of performance, but self-rated ability and satisfaction were highly correlated with one another. The importance of these findings is discussed and implications for nurse education are proposed.

Traditionally, research focussing on psychosocial factors in the construction industry has focused mainly on the negative aspects of health and on results such as occupational accidents. This study, however, focuses on the specific relationships among the different positive psychosocial factors shared by construction workers that could be responsible for occupational well-being and outcomes such as performance. The main objective of this study was to test whether personal resources predict self-rated job performance through job resources and work engagement. Following the predictions of Bandura's Social Cognitive Theory and the motivational process of the Job Demands-Resources Model, we expect that the relationship between personal resources and performance will be fully mediated by job resources and work engagement. The sample consists of 228 construction workers. Structural equation modelling supports the research model. Personal resources (i.e. self-efficacy, mental and emotional competences) play a predicting role in the perception of job resources (i.e. job control and supervisor social support), which in turn leads to work engagement and self-rated performance. This study emphasises the crucial role that personal resources play in determining how people perceive job resources by determining the levels of work engagement and, hence, their self-rated job performance. Theoretical and practical implications are discussed.

E-Health services comprise a broad range of healthcare services delivered by using information and communication technology. In order to support existing as well as emerging e-Health services over converged next generation network (NGN) architectures, there is a need for network QoS control mechanisms that meet the often stringent requirements of such services. In this paper, we evaluate the QoS support for e-Health services in the context of the Evolved Packet System (EPS), specified by the Third Generation Partnership Project (3GPP) as a multi-access all-IP NGN. We classify heterogeneous e-Health services based on context and network QoS requirements and propose a mapping to existing 3GPP QoS Class Identifiers (QCIs) that serve as a basis for the class-based QoS concept of the EPS. The proposed mapping aims to provide network operators with guidelines for meeting heterogeneous e-Health service requirements. As an example, we present the QoS requirements for a prototype e-Health service supporting tele-consultation between a patient and a doctor and illustrate the use of the proposed mapping to QCIs in standardized QoS control procedures.

This paper reports the views of participants from key multilaterals and related agencies in the evolving global negotiations on the post-2015 development agenda on the strategic location of sexual and reproductive health and rights. The research was carried out in June and July 2013, following the release of the report of the High-Level Panel of Eminent Persons on the Post-2015 Development Agenda, and comprised 40 semi-structured interviews with 57 participants and two e-mail respondents. All respondents were responsible for the post-2015 health and development agenda, or the post-2015 agenda more broadly, within their organisations. The interviews provide an insight into the intention to ensure that sexual and reproductive health and rights are integrated into the post-2015 trajectory by key players who sit at the interface of UN and Member State interaction. They reveal both an awareness of the shortcomings of the Millennium Development Goal process and its impact on advocacy for sexual and reproductive health and rights in early post-2015 engagement, as well as the vulnerability of sexual and reproductive health and rights in the remaining phases of post-2015 negotiations. Recent events bear these concerns out. Ensuring sexual and reproductive health and rights are included in the final post-2015 outcome document in the time remaining for negotiations, will be anything but a "doddle".

Using research from country case studies, this paper offers insights into the range of institutional and structural changes in development assistance between 2005 and 2011, and their impact on the inclusion of a sexual and reproductive health and rights agenda in national planning environments. At a global level during this period, donors supported more integrative modalities of aid - sector wide approaches, poverty reduction strategy papers, direct budgetary support - with greater use of economic frameworks in decision-making. The Millennium Development Goals brought heightened attention to maternal mortality, but at the expense of a broader sexual and reproductive health and rights agenda. Advocacy at the national planning level was not well linked to programme implementation; health officials were disadvantaged in economic arguments, and lacked financial and budgetary controls to ensure a connection between advocacy and action. With increasing competency in higher level planning processes, health officials are now refocusing the post-2015 development goals. If sexual and reproductive health and rights is to claim engagement across all its multiple elements, advocates need to link them to the key themes of sustainable development: inequalities in gender, education, growth and population, but also to urbanisation, migration, women in employment and climate change.

Health workforce shortages in Sub-Saharan Africa are widely recognized, particularly of physicians, leading the training and deployment of Non-physician clinicians (NPCs). The paper by Eyal et al provides interesting and legitimate viewpoints on evolving role of physicians in context of decisive increase of NPCss in Sub-Saharan Africa. Certainly, in short or mid-term, NPCs will continue to be a proxy solution and a valuable alternative to overcome physicians’ shortages in sub-Saharan Africa. Indeed, NPCs have an important role at primary healthcare (PHC) level. Physicians at PHC level can certainly have all different roles that were suggested by Eyal et al, including those not directly related to healthcare provision. However, at secondary and higher levels of healthcare, physicians would assume other roles that are mainly related to patient clinical care. Thus, attempting to generalize the role of physicians without taking into account the context where they will work would be not entirely appropriate. It is true that often physicians start the professional carriers at PHC level and progress to other levels of healthcare particularly after clinical post-graduation training. Nevertheless, the training programs offered by medical institutions in sub-Saharan Africa need to be periodically reviewed and take into account professional and occupational roles physicians would take in context of evolving health systems in sub-Saharan Africa.

Universal Health Coverage's evolving location in the post-2015 development agenda: Key informant perspectives within multilateral and related agencies during the first phase of post-2015 negotiations.
Brolan, Claire E; Hill, Peter S
In 2001, technocrats from four multilateral organizations selected the Millennium Development Goals mainly from the previous decade of United Nations (UN) summits and conferences. Few accounts are available of that significant yet cloistered synthesis process: none contemporaneous. In contrast, this study examines health's evolving location in the first-phase of the next iteration of global development goal negotiation for the post-2015 era, through the synchronous perspectives of representatives of key multilateral and related organizations. As part of the Go4Health Project, in-depth interviews were conducted in mid-2013 with 57 professionals working on health and the post-2015 agenda within multilaterals and related agencies. Using discourse analysis, this article reports the results and analysis of a Universal Health Coverage (UHC) theme: contextualizing UHC's positioning within the post-2015 agenda-setting process immediately after the Global Thematic Consultation on Health and High-Level Panel of Eminent Persons on the Post-2015 Development Agenda (High-Level Panel) released their post-2015 health and development goal aspirations in April and May 2013, respectively. After the findings from the interview data analysis are presented, the Results will be discussed drawing on Shiffman and Smith (Generation of political priority for global health initiatives: a framework and case study of maternal mortality.The Lancet2007; 370: : 1370-79) agenda-setting analytical framework (examining ideas, issues, actors and political context), modified by Benzianet al.(2011). Although more participants support the High-Level Panel's May 2013 report's proposal-'Ensure Healthy Lives'-as the next umbrella health goal, they nevertheless still emphasize the need for UHC to achieve this and thus be incorporated as part of its trajectory. Despite UHC's conceptual ambiguity and cursory mention in the High-Level Panel report, its proponents suggest its re-emergence will occur in

Prolonged stress (≥ six months) may cause a condition which has been named exhaustion disorder (ED) with ICD-10 code F43.8. ED is characterised by exhaustion, cognitive problems, poor sleep and reduced tolerance to further stress. ED can cause long term disability and depressive symptoms may develop. The aim was to construct and evaluate a self-rating scale, the Karolinska Exhaustion Disorder Scale (KEDS), for the assessment of ED symptoms. A second aim was to examine the relationship between self-rated symptoms of ED, depression, and anxiety using KEDS and the Hospital Anxiety and Depression Scale (HAD). Items were selected based on their correspondence to criteria for ED as formulated by the Swedish National Board of Health and Welfare (NBHW), with seven response alternatives in a Likert-format. Self-ratings performed by 317 clinically assessed participants were used to analyse the scale’s psychometric properties. KEDS consists of nine items with a scale range of 0–54. Receiver operating characteristics analysis demonstrated that a cut-off score of 19 was accompanied by high sensitivity and specificity (each above 95%) in the discrimination between healthy subjects and patients with ED. Reliability was satisfactory and confirmatory factor analysis revealed that ED, depression and anxiety are best regarded as different phenomena. KEDS may be a useful tool in the assessment of symptoms of Exhaustion Disorder in clinical as well as research settings. There is evidence that the symptom clusters of ED, anxiety and depression, respectively, reflect three different underlying dimensions. PMID:24236500

Transnational food retailers expanded to middle-income countries over recent decades responding to supply (liberalized foreign investment) and demand (rising incomes, urbanization, female workforce participation, and time poverty). Control in new markets diffuses along three axes: socio-economic (rich to poor), geographic (urban to rural), and product category (processed foods to fresh foods). We used a mixed method approach to study the progression of modern retail in Thailand on these three axes and consumer preferences for food retailing. In Thailand modern retail controls half the food sales but traditional fresh markets remain important. Quantitative questionnaires administered to members of a large national cohort study revealed around half of respondents were primarily traditional shoppers and half either utilized modern and traditional formats equally or primarily shopped at supermarkets. Fresh foods were mainly purchased at traditional retail formats and dry packaged foods at supermarkets. Qualitative interviews found price and quality of produce and availability of culturally important products to be significant reasons for continued support of fresh markets. Our results show socio-economic and geographic diffusion is already advanced with most respondents having access to and utilizing modern retail. Control of the fresh food sector by transnationals faces barriers in Thailand and may remain elusive. The short to mid-term outcome may be a bifurcated food system with modern and traditional retail each retaining market share, but fresh markets longer term survival may require government assistance as supermarkets become more established. Fresh markets supply affordable, healthy foods, and livelihoods for poorer Thais and are repositories of Thai food culture and social networks. If they survive they will confer cultural, social, economic, and health benefits.

The study assessed television viewing >2 h a day and its association with sedentary behaviors, self-rated health, and academic performance among secondary school adolescents. A cross-sectional survey was conducted among randomly selected students in Lima in 2015. We measured self-reported responses of students using a standard questionnaire, and conducted in-depth interviews with 10 parents and 10 teachers. Chi-square test, correlation and multivariate logistic regression analysis were performed among 1234 students, and thematic analysis technique was used for qualitative information. A total of 23.1% adolescents reported watching television >2 h a day. Qualitative findings also show that adolescents spend most of their leisure time watching television, playing video games or using the Internet. Television viewing had a significant positive correlation with video game use in males and older adolescents, with Internet use in both sexes, and a negative correlation with self-rated health and academic performance in females. Multivariate logistic regression analysis shows that television viewing >2 h a day, independent of physical activity was associated with video games use >2 h a day, Internet use >2 h a day, poor/fair self-rated health and poor self-reported academic performance. Television viewing time and sex had a significant interaction effect on both video game use >2 h a day and Internet use >2 h a day. Reducing television viewing time may be an effective strategy for improving health and academic performance in adolescents.

Physician-rating scales remain the standard in antidepressant clinical trials. The current study aimed to examine the discrepancies between physician-rating scales and self-rating scales for symptoms and functioning, before and after treatment, in newly hospitalized patients. A total of 131 acutely ill inpatients with major depressive disorder were enrolled to receive 20 mg of fluoxetine daily for 6 weeks. Symptom severity and functioning were assessed at baseline and again at week 6. Symptom severity was rated using the 17-item Hamilton Depression Rating Scale (HDRS-17) and the Zung Self-rating Depression Scale (ZDS). Functioning was measured by the Global Assessment of Functioning (GAF) and the Work and Social Adjustment Scale (WSAS). Pearson correlation coefficients (r) between HDRS-17 and ZDS and between GAF and WSAS were calculated at week 0 and week 6. Sensitivity to change was measured using effect sizes. One-hundred twelve patients completed the 6-week trial. After 6 weeks of treatment, correlations between HDRS-17 and ZDS or correlations between GAF and WSAS became larger from baseline to end point. All correlations were statistically significant (P < 0.001). Effect sizes measured by physician-rating scales (ie, HDRS-17 and GAF) were larger than by self-rating scales (ie, ZDS and WSAS). Correlations between baseline physician-rating scale scores and self-rating scale scores improved after 6 weeks of treatment. Physician-rating scales had larger effect sizes than self-rating scales. Physician-rating scales were more sensitive in detecting symptom or functional changes than self-rating scales.

An evolvable synthetic neural system includes an evolvable neural interface operably coupled to at least one neural basis function. Each neural basis function includes an evolvable neural interface operably coupled to a heuristic neural system to perform high-level functions and an autonomic neural system to perform low-level functions. In some embodiments, the evolvable synthetic neural system is operably coupled to one or more evolvable synthetic neural systems in a hierarchy.

Health Care Aides (HCAs) provide up to 80% of the direct care to older Canadians living in long-term care facilities, or in their homes. They are an understudied workforce, and calls for health human resources strategies relating to these workers are, we feel, precipitous. First, we need a better understanding of the nature and scope of their work, and of the factors that shape it. Here, we discuss the evolving role of HCAs and the factors that impact how and where they work. The work of HCAs includes role-required behaviors, an increasing array of delegated acts, and extra-role behaviors like emotional support. Role boundaries, particularly instances where some workers over-invest in care beyond expected levels, are identified as one of the biggest concerns among employers of HCAs in the current cost-containment environment. A number of factors significantly impact what these workers do and where they work, including market-level differences, job mobility, and work structure. In Canada, entry into this 'profession' is increasingly constrained to the Home and Community Care sector, while market-level and work structure differences constrain job mobility to transitions of only the most experienced workers, to the long-term care sector. We note that this is in direct opposition to recent policy initiatives designed to encourage aging at home. Work structure influences what these workers do, and how they work; many HCAs work for three or four different agencies in order to sustain themselves and their families. Expectations with regard to HCA preparation have changed over the past decade in Canada, and training is emerging as a high priority health human resource issue. An increasing emphasis on improving quality of care and measuring performance, and on integrated team-based care delivery, has considerable implications for worker training. New models of care delivery foreshadow a need for management and leadership expertise--these workers have not historically been

Background and Aims Adjacent flowers on Mimulus ringens floral displays often vary markedly in selfing rate. We hypothesized that this fine-scale variation in mating system reflects the tendency of bumble-bee pollinators to probe several flowers consecutively on multiflower displays. When a pollinator approaches a display, the first flower probed is likely to receive substantial outcross pollen. However, since pollen carryover in this species is limited, receipt of self pollen should increase rapidly for later flowers. Here the first direct experimental test of this hypothesis is described. Methods In order to link floral visitation sequences with selfing rates of individual flowers, replicate linear arrays were established, each composed of plants with unique genetic markers. This facilitated unambiguous assignment of paternity to all sampled progeny. A single wild bumble-bee was permitted to forage on each linear array, recording the order of floral visits on each display. Once fruits had matured, 120 fruits were harvested (four flowers from each of five floral displays in each of six arrays). Twenty-five seedlings from each fruit were genotyped and paternity was unambiguously assigned to all 3000 genotyped progeny. Key Results The order of pollinator probes on Mimulus floral displays strongly and significantly influenced selfing rates of individual fruits. Mean selfing rates increased from 21 % for initial probes to 78 % for the fourth flower probed on each display. Conclusions Striking among-flower differences in selfing rate result from increased deposition of geitonogamous (among-flower, within-display) self pollen as bumble-bees probe consecutive flowers on each floral display. The resulting heterogeneity in the genetic composition of sibships may influence seedling competition and the expression of inbreeding depression. PMID:19218584

Sleep interventions have rarely explored reductions in night-to-night fluctuations [i.e. intra-individual variability (IIV)] in sleep, despite the negative impacts of such fluctuations on affective states and cognitive and physical symptoms. In a community-based randomized controlled trial we evaluated whether physical exercise reduced IIV in self-rated sleep outcomes among middle-aged and older adults with sleep complaints. Under-active adults 55 years and older (n = 66, 67% women) with mild to moderate sleep complaints were randomized to 12 months of a moderate-intensity endurance exercise (n = 36) or a health education control group (n = 30). Daily sleep logs, Pittsburgh Sleep Quality Index (PSQI) and in-home polysomnographic sleep recordings (PSG) were collected at baseline, 6 months and 12 months. Sleep log-derived means and IIV were computed for sleep-onset latency (SOL), time in bed, feeling rested in the morning, number of nighttime awakenings, and wake after final awakening (WAFA). Using intent-to-treat methods, at 6 months no differences in IIV were observed by group. At 12 months, SOL-based IIV was reduced in the exercise group compared with the control (difference = 23.11, 95% CI: 3.04-47.18, P = 0.025, Cohen's d = 0.57). This change occurred without mean-level or IIV changes in sleep-wake schedules. For all sleep variables, except SOL and WAFA, IIV changes and mean-level changes in each variable were negatively correlated (r = -0.312 to -0.691, P < 0.05). Sleep log-derived IIV changes were modestly correlated with mean-level PSQI and PSG-based changes at 12 months. Twelve months of moderate-intensity exercise reduced night-to-night fluctuations in self-rated time to fall asleep, and this relationship was independent of mean-level time to fall asleep.

Maternal depression has been widely studied but paternal depression is often overlooked. Depression in men is generally more difficult to detect as the symptoms are not apparent. Furthermore, Japanese couples tend to suppress their real emotions to avoid confrontation. We aimed to investigate the reliability and validity of the K6, K10 and PHQ-9 in assessing the mental health status of men when used by their pregnant partners, as well as the prevalence of paternal prenatal depression in a Japanese study sample. A total of 136 couples participated in this study. The prevalence of paternal prenatal depression reported by the men themselves was higher compared to that reported by their female partners (K6, 10.3 %; K10, 6.6 %; PHQ-9, 3.7 % vs. K6-FP, 2.2 %; K10-FP, 1.5 %; PHQ-9-FP, 0 %, respectively). Mental health issues in men may not be accurately rated by their female partners, suggesting the importance of self-rating and direct consultation.

In the last two decades, quality of life and health-related quality of life have become commonly used outcome measures in the large number of studies evaluating healthcare and home care nursing. The objective of this systematic search and review was to evaluate studies that include self-rated generic quality of life instrument used among elderly patients receiving home care nursing. Searches were conducted in Medline, Embase, PsycINFO and Cinahl for articles published between January 2005 and June 2016, with 17 studies in eight countries meeting the inclusion criteria and assessed for quality. Overall, the review shows great variations in the included studies regarding characteristics of the participants and place of origin, the generic quality of life instruments applied and their dimensions. In this review, we raise the question of whether the generic questionnaires used to measure quality of life do in fact measure what is essential for quality of life in elderly users of home care nursing. The psychological and physical dimensions of quality of life were assessed in almost all included studies, while older-specific dimensions like autonomy, control and sensation were less frequently assessed. There is reason to believe that generic quality of life instruments frequently do not capture the dimensions that are most important for elderly people with health problems in need of home care nursing.

Abstract Introduction Medically unexplained symptoms (MUS) are very common in family medicine, despite being a poorly-defined clinical entity. This study aimed to evaluate the effect of an educational intervention (EI) on self-rated quality of life, treatment satisfaction, and the family physician-patient relationship in patients with MUS. Methods In a multi-centre longitudinal intervention study, which was performed between 2012 and 2014, patients were asked to rate their quality of life, assess their depression, anxiety, stress and somatisation, complete the Hypochondriasis Index, the Medical Interview Satisfaction Scale and the Patient Enablement Instrument for assessing the physician-patient relationship, before and after the EI. Results The mean values before and after the intervention showed that after the EI, patients with MUS gave a lower (total) mean rating of their health issues and a higher rating of their quality of life, and they also had a more positive opinion of their relationship with the physician (p<0.05). However, there were no differences in the (total) rating of treatment satisfaction before and after the EI (p=0.423). Significant differences in the symptoms in patients with MUS before and after the intervention were confirmed for stress, somatisation and hypochondriasis (p<0.05). Conclusions It could be beneficial to equip family physicians with the knowledge, skills and tools to reduce hypochondriasis and somatisation in MUS patients, which would improve patients’ self-rated health status.

Genomic medicine is rapidly evolving. Next-generation sequencing is changing the diagnostic paradigm by allowing genetic testing to be carried out more quickly, less expensively and with much higher resolution; pushing the envelope on existing moral norms and legal regulations. Early experience with implementation of next-generation sequencing to diagnose rare genetic conditions in symptomatic children suggests ways that genomic medicine might come to be used and some of the ethical issues that arise, impacting test design, patient selection, consent, sequencing analysis and communication of results. The ethical issues that arise from use of new technologies cannot be satisfactorily analyzed until they are understood and they cannot be understood until the technologies are deployed in the real world.

The present study predicted vocational purpose from thinking styles, a construct at the interface of intelligence and personality. 233 students majoring in history and computer science from a large research-oriented university in the People's Republic of China completed the Thinking Styles Inventory and the Iowa Vocational Purpose Inventory. The participants also rated their own analytical, creative, and practical abilities. In general, results indicated that thinking styles contributed to vocational purpose beyond self-rated abilities. Specifically, the more creativity-generating and complex thinking styles tended to contribute positively to vocational purpose, whereas the more conforming and simplistic thinking styles tended to contribute negatively to vocational purpose. This article points to the need theoretically for integrating the construct of thinking style into the definition of differential psychology. Practical data argue for a collaborative working relationship between teachers and vocational counselors in institutions of higher education.

Organization skills are defined broadly to include both materials and temporal features. Given its symptoms and neurobiological features, attention-deficit hyperactivity disorder (ADHD) should be susceptible to impairment in organization. A valid organization scale is imperative to assess and intervene individuals with ADHD. However, there is no validated organization scale in Japan. Referring to existing scales and clinical experience, the self-rating organization scale (SOS) was developed and tested in terms of its psychometric properties with 1,017 adults and students including 47 adults with ADHD. Additionally, cutoffs for disorganization were set for clinical utility. Three factors (materials disorganization, temporal disorganization, and mess) were extracted by factor analyses. The index for reliability and validity of the SOS was acceptable. The factor "mess" could reflect the unique aspect of the Japanese environment. Further study is needed to enhance the clinical utility of the SOS.

People often claim that they perform better in memory performance tasks when they are more motivated. However, past research has shown minimal effects of motivation on memory performance when factors contributing to item-specific biases during encoding and retrieval are taken into account. The purpose of the present study was to examine the generality of this apparent dissociation by using more sensitive measures of experienced motivation and memory performance. Extrinsic motivation was manipulated through competition instructions, and subjective ratings of intrinsic and extrinsic motivation were obtained before and after study instructions. Participants studied a series of words, and memory performance was assessed by content recall (Experiment 1) and source recall (Experiment 2). Both experiments showed dissociation between subjective ratings of extrinsic motivation and actual memory performance, so that competition increased self-rated extrinsic motivation but had no effects on memory performance, including source recall. Inconsistent with most people's expectations, the findings suggest that extrinsic motivation has minimal effects on memory performance.

Background Massive efforts in Canada have been made to renew primary healthcare. However, although early evaluations of initiatives and research on certain aspects of the reform are promising, none have examined the link between patient assessments of care and health outcomes or the impacts at a population level. The goal of this project is to examine the effect of patient-centred and effective primary healthcare on the evolution of chronic illness burden and health functioning in a population, and in particularly vulnerable groups: the multi-morbid and the poor. Methods/Design A randomly selected cohort of 2000 adults aged 25 to 75 years will be recruited within the geographic boundaries of four local healthcare networks in Quebec. At recruitment, cohort members will report on socio-demographic information, functional health and healthcare use. Two weeks, 12 months and 24 months after recruitment, cohort participants will complete a self-administered questionnaire on current health and health behaviours in order to evaluate primary healthcare received in the previous year. The dependent variables are calculated as change over time of functional health status, chronic illness burden, and health behaviours. Dimensions of patient-centred care and clinical processes are measured using sub-scales of validated instruments. We will use Poisson regression modelling to estimate the incidence rate of chronic illness burden scores and structural equation modelling to explore relationships between variables and to examine the impact of dimensions of patient-centred care and effective primary healthcare. Discussion Results will provide valuable information for primary healthcare clinicians on the course of chronic illness over time and the impact on health outcomes of accessible, patient-centred and effective care. A demonstration of impact will contribute to the promotion of continuous quality improvement activities at a clinical level. While considerable advances have been

The motivational styles of 25 children with attention-deficit/hyperactivity disorder, combined type (ADHD/C), 13 children with ADHD, inattentive type (ADHD/IA), and 25 nondiagnosed controls (NC) were compared using parent, teacher, and self-ratings. Both ADHD subtypes demonstrated motivational impairment characterized by a preference for easy work, less enjoyment of learning, less persistence, and a greater reliance on external than on internal standards to judge their performance relative to NC. Some motivational style differences between ADHD subtypes were also revealed, with the ADHD/C group more motivated by competitiveness and a desire to be perceived as superior to others and the ADHD/IA group less uncooperative and possibly more passive in their learning styles. When IQ was statistically controlled, these results were generally unchanged. The contributing role of motivational deficits to the generally poor academic functioning of children with ADHD is discussed, along with potential intervention implications of the divergent motivational styles of different ADHD subtypes.

This population-based cross-sectional study examined the relationship between self-rated living environment and excess body weight in a sample of 216 adults from Itirapuã, São Paulo State, Brazil. Logistic regression adjusted for gender and age showed that people living far from outdoor areas for physical exercise [OR = 2.05 (95%CI: 1.15; 3.66)] and primary schools [OR = 1.99 (95%CI: 1.13; 3.47)] had higher odds of excess weight. Satisfaction with the quality of available supermarkets [OR = 0.14 (95%CI: 0.03; 0.69) p = 0.02], adequate street lighting [OR = 0.37 (95%CI: 0.14; 0.96) p = 0.02], and pedestrians walking on sidewalks within one's line-of-sight [OR = 0.41 (95%CI: 0.18; 0.94) p = 0.03] were inversely associated with excess weight. The results suggest that small-town individuals' negative perceptions of their living environment are associated with excess weight.

The Children's Sleep Comic is a standardized self-report questionnaire for assessing insomnia in children ages 5-11 years. The goal of the present study is to introduce a revised version of this measure and to present psychometrics and a cut-off score. Therefore, the revised Children's Sleep Comic, the Sleep Self Report, the Children's Sleep Habits Questionnaire, and the Child Behavior Checklist were applied to a sample of 393 children and their parents. Of the parents who participated voluntarily, a subsample (n = 176) was interviewed on the phone to diagnose their children with sleep disorders according to the International Classification of Sleep Disorders, if applicable. The results indicated that the Children's Sleep Comic is a reliable self-rating instrument for diagnosing childhood insomnia. Internal consistency was α = 0.83; and convergent and divergent validity were adequate. The child-friendly format can foster a good therapeutic relationship, and thus establish the basis for successful intervention.
Dream books have a very long history, but systematic research on how many people have read magazine articles or books on dreams and whether reading such literature is beneficial to the dreamer is scarce. In the present sample of 444 people (mostly psychology students), about 75% of the participants stated that they had read at least one magazine article on dreams, and more than 40% had read at least one book about dreams. The main factor associated with the frequency of reading dream literature was a positive attitude toward dreaming, whereas personality factors play a minor role in explaining interindividual differences in this variable. The self-rated benefit of reading dream literature varied greatly, from not helpful at all to very helpful, and was associated with dream recall frequency and positive attitude toward dreaming. Using this approach in a more sophisticated way, eliciting details about the kinds of information participants have read would help researchers learn more about what techniques of dream work are effective and thus complement the research carried out in therapist-guided sessions.

Aim To investigate abnormalities in automatic information processing related to self- and observer-rated alexithymia, especially with regard to somatization, controlling for confounding variables such as depression and affect. Sample 89 healthy subjects (60% female), aged 19–71 years (M = 32.1). 58 subjects were additionally rated by an observer. Measures Alexithymia (self-rating: TAS-20, observer rating: OAS); automatic information processing (priming task including verbal [illness-related, negative, positive, neutral] and facial [negative, positive, neutral] stimuli); somatoform symptoms (SOMS-7T); confounders: depression (BDI), affect (PANAS). Results Higher self-reported alexithymia scores were associated with lower reaction times for negative (r = .19, p < .10) and positive (r = .26, p < .05) verbal primes when the target was illness-related. Self-reported alexithymia was correlated with number (r = .42, p < .01) and intensity of current somatoform symptoms (r = .36, p < .01), but unrelated to observer-rated alexithymia (r = .11, p = .42). Discussion Results indicate a faster allocation of attentional resources away from task-irrelevant information towards illness-related stimuli in alexithymia. Considering the close relationship between alexithymia and somatization, these findings are compatible with the theoretical view that alexithymics focus strongly on bodily sensations of emotional arousal. A single observer rating (OAS) does not seem to be an adequate alexithymia-measure in community samples. PMID:26090893

We propose a novel modular network called the Self-Evolving Modular Network (SEEM). The SEEM has a modular network architecture with a graph structure and these following advantages: (1) new modules are added incrementally to allow the network to adapt in a self-organizing manner, and (2) graph's paths are formed based on the relationships between the models represented by modules. The SEEM is expected to be applicable to evolving functions of an autonomous robot in a self-organizing manner through interaction with the robot's environment and categorizing large-scale information. This paper presents the architecture and an algorithm for the SEEM. Moreover, performance characteristic and effectiveness of the network are shown by simulations using cubic functions and a set of 3D-objects.

The Evolvable Neural Software System (ENSS) is composed of sets of Neural Basis Functions (NBFs), which can be totally autonomously created and removed according to the changing needs and requirements of the software system. The resulting structure is both hierarchical and self-similar in that a given set of NBFs may have a ruler NBF, which in turn communicates with other sets of NBFs. These sets of NBFs may function as nodes to a ruler node, which are also NBF constructs. In this manner, the synthetic neural system can exhibit the complexity, three-dimensional connectivity, and adaptability of biological neural systems. An added advantage of ENSS over a natural neural system is its ability to modify its core genetic code in response to environmental changes as reflected in needs and requirements. The neural system is fully adaptive and evolvable and is trainable before release. It continues to rewire itself while on the job. The NBF is a unique, bilevel intelligence neural system composed of a higher-level heuristic neural system (HNS) and a lower-level, autonomic neural system (ANS). Taken together, the HNS and the ANS give each NBF the complete capabilities of a biological neural system to match sensory inputs to actions. Another feature of the NBF is the Evolvable Neural Interface (ENI), which links the HNS and ANS. The ENI solves the interface problem between these two systems by actively adapting and evolving from a primitive initial state (a Neural Thread) to a complicated, operational ENI and successfully adapting to a training sequence of sensory input. This simulates the adaptation of a biological neural system in a developmental phase. Within the greater multi-NBF and multi-node ENSS, self-similar ENI s provide the basis for inter-NBF and inter-node connectivity.

We report on the longitudinal stability of personality traits across an average 40 years in the Hawaii Personality and Health Cohort relating childhood teacher assessments of personality to adult self- and observer- reports. Stabilities based on self-ratings in adulthood were compared to those measured by the Structured Interview for the Five-Factor Model (SIFFM; Trull & Widiger, 1997), and trait ratings completed by interviewers. Although convergence between self-reports and observer-ratings was modest, childhood traits demonstrated similar levels of stability across methods in adulthood. Extraversion and Conscientiousness generally showed higher stabilities, whereas Neuroticism showed none. For Agreeableness and Intellect/Openness, stability was highest when assessed with observer-ratings. These findings are discussed in terms of differences in trait evaluativeness and observability across measurement methods.

This study sought to investigate the level of knowledge of language constructs in a cohort of Australian teachers and to examine their self-rated ability and confidence in that knowledge. Seventy-eight teachers from schools across the Australian state of Victoria completed a questionnaire which included items from existing measures, as well as newly developed items. Consistent with a number of earlier Australian and international studies, teachers' explicit and implicit knowledge of basic linguistic constructs was limited and highly variable. A statistically significant correlation was found between (1) total self-rated ability and (2) years since qualification and experience teaching the early years of primary school; however, no relationship was found between self-rated ability and overall performance on knowledge items. Self-rated ability to teach phonemic awareness and phonics had no relationship with demonstrated knowledge in these areas. Teachers were most likely to rate their ability to teach skills including spelling, phonics, comprehension or vocabulary as either moderate or very good. This was despite most respondents demonstrating limited knowledge and stating that they did not feel confident answering questions about their knowledge in these areas. The findings from this study confirm that in the field of language and literacy instruction, there is a gap between the knowledge that is theoretically requisite, and therefore expected, and the actual knowledge of many teachers. This finding challenges current pre-service teacher education and in-service professional learning.

The proposition that chewing gum can improve alertness was investigated via both physiological and self-rated measures. The Pupillographic Sleepiness Test (PST) provided a measure of pupillary unrest (PUI); a physiological index of daytime sleepiness. Chewing gum reduced the extent of sleepiness as measured by both PUI and self-rated sleepiness. Specifically, in comparison with sham chewing and no chewing controls, the chewing gum condition significantly limited the increase in pupillary unrest following the 11-minute PST within a darkened laboratory: a finding indicating moderation of the daytime sleepiness increase for the chewing gum condition. In addition, there was some evidence that chewing gum (relative to the no-chewing condition only) moderated the increase in a self-rated measure of sleepiness (Stanford Sleepiness Scale). However, there was no evidence that chewing gum moderated the decrease in self-rated alertness (Bond-Lader Visual Analogue Mood Scale). Although the precise mechanism underpinning the effect of chewing gum is unclear, the reduction in daytime sleepiness may be underpinned via heightened cerebral activity following the chewing of gum or the arousing effects of mint flavour.

Professor Blumstein's timely article deals with two competing paradigms that provide the poles in the spectrum of legal liability regimes. The "professional" or "scientific" model of liability assumes a rigidly normative approach to medical practice while the second more recent paradigm reflects the principles of marketplace economics in considering cost and resource availability to determine quality of care standards. Professor Blumstein concludes that the traditional approach to determining legal liability is being eroded by both the economics of managed care and the recent emphasis on systemic management of health care to promote patient safety, and that the traditional regime will have to "bend" in order to remain legally viable.

The ways in which the IUE has proved useful in studying highly evolved stars are reviewed. The importance of high dispersion spectra for abundance analyses of the sd0 stars and for studies of the wind from the central star of NGC 6543 and the wind from the 0 type component of Vela X-1 is shown. Low dispersion spectra are used for absolute spectrophotometry of the dwarf nova, Ex Hya. Angular resolution is important for detecting and locating UV sources in globular clusters.

The Regolith Evolved Gas Analyzer (REGA) is a high-temperature furnace and mass spectrometer instrument for determining the mineralogical composition and reactivity of soil samples. REGA provides key mineralogical and reactivity data that is needed to understand the soil chemistry of an asteroid, which then aids in determining in-situ which materials should be selected for return to earth. REGA is capable of conducting a number of direct soil measurements that are unique to this instrument. These experimental measurements include: (1) Mass spectrum analysis of evolved gases from soil samples as they are heated from ambient temperature to 900 C; and (2) Identification of liberated chemicals, e.g., water, oxygen, sulfur, chlorine, and fluorine. REGA would be placed on the surface of a near earth asteroid. It is an autonomous instrument that is controlled from earth but does the analysis of regolith materials automatically. The REGA instrument consists of four primary components: (1) a flight-proven mass spectrometer, (2) a high-temperature furnace, (3) a soil handling system, and (4) a microcontroller. An external arm containing a scoop or drill gathers regolith samples. A sample is placed in the inlet orifice where the finest-grained particles are sifted into a metering volume and subsequently moved into a crucible. A movable arm then places the crucible in the furnace. The furnace is closed, thereby sealing the inner volume to collect the evolved gases for analysis. Owing to the very low g forces on an asteroid compared to Mars or the moon, the sample must be moved from inlet to crucible by mechanical means rather than by gravity. As the soil sample is heated through a programmed pattern, the gases evolved at each temperature are passed through a transfer tube to the mass spectrometer for analysis and identification. Return data from the instrument will lead to new insights and discoveries including: (1) Identification of the molecular masses of all of the gases

Self-rating Anxiety Scale (SAS), introduced by Zung, has been widely used in research and in clinical practice for the detection of anxiety. The present study aims at standardizing the Greek version of SAS. SAS consists of 20 items rated on a 1-4 likert type scale. The total SAS score may vary from 20 (no anxiety at all) to 80 (severe anxiety). Two hundred and fifty four participants (114 male and 140 female), psychiatric patients, physically ill and general population individuals, aged 45.40±11.35 years, completed the following: (a) a demographic characteristics' questionnaire, (b) the SAS Greek version, (c) the Spielberg's Modified Greek State-Trait Anxiety Scale (STAI-Gr.-X) and (d) the Zung Depression Rating Scale (ZDRS). Seventy six participants answered the SAS twice within a 12th-day median period of time. The following parameters were calculated: (a) internal consistency of the SAS in terms of Cronbach's α co-efficient, (b) its test-retest reliability in terms of the Intraclass Correlation Coefficient (ICC) and (c) its concurrent and convergent validities through its score's Spearman's rho correlations with both the state and trait subscales of STAI-Gr X and the ZDRS. In addition, in order to evaluate SAS' discriminant validity, the scale's scores of the three groups of participants (psychiatric patients, physically ill and general population individuals) were compared among each other, in terms of Kruskall Wallis and Mann Whitney U tests. SAS Cronbach's alpha equals 0.897 while ICC regarding its test-retest reliability equals 0.913. Spearman's rho concerning validity: (a) when SAS is compared to STAI-Gr.-X (state), equals it 0.767, (b) when SAS is compared to STAI-Gr. X (trait), it equals 0.802 and (c) when SAS is compared to ZDRS, it equals 0.835. The mentally ill scored significantly higher in SAS compared to both the healthy and the general population. In conclusion, the SAS Greek version presents very satisfactory psychometric properties regarding

In 2001, technocrats from four multilateral organizations selected the Millennium Development Goals mainly from the previous decade of United Nations (UN) summits and conferences. Few accounts are available of that significant yet cloistered synthesis process: none contemporaneous. In contrast, this study examines health’s evolving location in the first-phase of the next iteration of global development goal negotiation for the post-2015 era, through the synchronous perspectives of representatives of key multilateral and related organizations. As part of the Go4Health Project, in-depth interviews were conducted in mid-2013 with 57 professionals working on health and the post-2015 agenda within multilaterals and related agencies. Using discourse analysis, this article reports the results and analysis of a Universal Health Coverage (UHC) theme: contextualizing UHC’s positioning within the post-2015 agenda-setting process immediately after the Global Thematic Consultation on Health and High-Level Panel of Eminent Persons on the Post-2015 Development Agenda (High-Level Panel) released their post-2015 health and development goal aspirations in April and May 2013, respectively. After the findings from the interview data analysis are presented, the Results will be discussed drawing on Shiffman and Smith (Generation of political priority for global health initiatives: a framework and case study of maternal mortality. The Lancet 2007; 370: 1370–79) agenda-setting analytical framework (examining ideas, issues, actors and political context), modified by Benzian et al. (2011). Although more participants support the High-Level Panel’s May 2013 report’s proposal—‘Ensure Healthy Lives’—as the next umbrella health goal, they nevertheless still emphasize the need for UHC to achieve this and thus be incorporated as part of its trajectory. Despite UHC’s conceptual ambiguity and cursory mention in the High-Level Panel report, its proponents suggest its re

Kwan, John, Kenny, Bond, and Robins conceptualize self-enhancement as a favorable comparison of self-judgments with judgments of and by others. Applying a modified version of Kwan et al.'s approach to behavior observation data, we show that the resulting measure of self-enhancement bias is highly reliable, predicts self-ratings of intelligence as well as does actual intelligence, interacts with item desirability in predicting responses to questionnaire items, and also predicts general life satisfaction. Consistent with previous research, however, self-ratings of intelligence did not become more valid when controlling for self-enhancement bias. We also show that common personality scales like the Rosenberg Self-Esteem Scale reflect self-enhancement at least as strongly as do scales that were designed particularly for that purpose (i.e., "social desirability scales"). The relevance of these findings in regard to the validity and utility of social desirability scales is discussed.

The primitive land plant life cycle featured the production of spores of unimodal size, a condition called homospory. The evolution of bimodal size distributions with small male spores and large female spores, known as heterospory, was an innovation that occurred repeatedly in the history of land plants. The importance of desiccation-resistant spores for colonization of the land is well known, but the adaptive value of heterospory has never been well established. It was an addition to a sexual life cycle that already involved male and female gametes. Its role as a precursor to the evolution of seeds has received much attention, but this is an evolutionary consequence of heterospory that cannot explain the transition from homospory to heterospory (and the lack of evolutionary reversal from heterospory to homospory). Enforced outcrossing of gametophytes has often been mentioned in connection to heterospory, but we review the shortcomings of this argument as an explanation of the selective advantage of heterospory. Few alternative arguments concerning the selective forces favouring heterospory have been proposed, a paucity of attention that is surprising given the importance of this innovation in land plant evolution. In this review we highlight two ideas that may lead us to a better understanding of why heterospory evolved. First, models of optimal resource allocation - an approach that has been used for decades in evolutionary ecology to help understand parental investment and other life-history patterns - suggest that an evolutionary increase in spore size could reach a threshold at which small spores yielding small, sperm-producing gametophytes would return greater fitness per unit of resource investment than would large spores and bisexual gametophytes. With the advent of such microspores, megaspores would evolve under frequency-dependent selection. This argument can account for the appearance of heterospory in the Devonian, when increasingly tall and complex

The evolution of plastids from cyanobacteria is believed to represent a singularity in the history of life. The enigmatic amoeba Paulinella and its 'recently' acquired photosynthetic inclusions provide a fascinating system through which to gain fresh insight into how endosymbionts become organelles.The plastids, or chloroplasts, of algae and plants evolved from cyanobacteria by endosymbiosis. This landmark event conferred on eukaryotes the benefits of photosynthesis--the conversion of solar energy into chemical energy--and in so doing had a huge impact on the course of evolution and the climate of Earth 1. From the present state of plastids, however, it is difficult to trace the evolutionary steps involved in this momentous development, because all modern-day plastids have fully integrated into their hosts. Paulinella chromatophora is a unicellular eukaryote that bears photosynthetic entities called chromatophores that are derived from cyanobacteria and has thus received much attention as a possible example of an organism in the early stages of organellogenesis. Recent studies have unlocked the genomic secrets of its chromatophore 23 and provided concrete evidence that the Paulinella chromatophore is a bona fide photosynthetic organelle 4. The question is how Paulinella can help us to understand the process by which an endosymbiont is converted into an organelle.

Cooperators forgo their own interests to benefit others. This reduces their fitness and thus cooperators are not likely to spread based on natural selection. Nonetheless, cooperation is widespread on every level of biological organization ranging from bacterial communities to human society. Mathematical models can help to explain under which circumstances cooperation evolves. Evolutionary game theory is a powerful mathematical tool to depict the interactions between cooperators and defectors. Classical models typically involve either pairwise interactions between individuals or a linear superposition of these interactions. For interactions within groups, however, synergetic effects may arise: their outcome is not just the sum of its parts. This is because the payoffs via a single group interaction can be different from the sum of any collection of two-player interactions. Assuming that all interactions start from pairs, how can such synergetic multiplayer games emerge from simpler pairwise interactions? Here, we present a mathematical model that captures the transition from pairwise interactions to synergetic multiplayer ones. We assume that different social groups have different breaking rates. We show that non-uniform breaking rates do foster the emergence of synergy, even though individuals always interact in pairs. Our work sheds new light on the mechanisms underlying such synergetic interactions. PMID:27466437

Introducción y objetivo: Una mayor adherencia a la dieta mediterránea es un factor protector de la mortalidad atribuida principalmente a las enfermedades crónico-degenerativas en países desarrollados. La salud auto-percibida constituye un buen indicador para medir el estado de salud poblacional y como predictor de la mortalidad. Son escasos los estudios que han explorado la relación entre la adherencia a la dieta mediterránea y la salud auto- percibida especialmente en población joven. En este estudio analizamos los factores relacionados con el estado de salud auto-percibido en población joven universitaria, prestando especial atención a la adherencia a un patrón de dieta mediterránea definido a priori. Método: Se han analizado los datos de 1110 participantes recogidos en el momento de ingreso en el del Estudio Di- SA-UMH (Dieta, Salud y Antropometría en universitarios de la Universidad Miguel Hernández). La dieta se evaluó mediante cuestionario de frecuencia alimentaria validado y se estimó la adherencia a la dieta mediterránea mediante el índice relative Mediterranean Diet Score que incluye 9 componentes y un rango entre 0-18 puntos. El estado de salud auto-percibida se recogió mediante la pregunta “En general, ¿cómo diría que es su salud?” con cinco opciones: muy buena, buena, regular, mala y muy mala. Se recogió información sobre variables sociodemográficas y estilos de vida. Se usó regresión logística multinomial (usando razón de riesgos relativos RRR) para analizar la asociación entre adherencia a la dieta mediterránea (rMED baja: 0-6; media: 7-10 puntos; alta: 11-18) y salud auto-percibida (muy buena (referencia), buena y regular/mala/muy mala). Resultados: Un 26.8%, 58.7% y 14.4% de los participantes presentaron respectivamente una adherencia a la dieta mediterránea baja, media o alta; un 23.1%, 65.1% y 11.8%, refirieron una salud muy buena, buena o regu lar/mala/muy mala, respectivamente. En el análisis multivariante, una menor adherencia a la dieta mediterránea se asoció significativamente a un peor estado de salud auto-percibido (p.

We present a system that can evolve the morphology and the controller of virtual walking and block-throwing creatures (catapults) using a genetic algorithm. The system is based on Sims' work, implemented as a flexible platform with an off-the-shelf dynamics engine. Experiments aimed at evolving Sims-type walkers resulted in the emergence of various realistic gaits while using fairly simple objective functions. Due to the flexibility of the system, drastically different morphologies and functions evolved with only minor modifications to the system and objective function. For example, various throwing techniques evolved when selecting for catapults that propel a block as far as possible. Among the strategies and morphologies evolved, we find the drop-kick strategy, as well as the systematic invention of the principle behind the wheel, when allowing mutations to the projectile.

Previous research using self-report measures has shown an association between nonsuicidal self-injurious behavior (NSSI) and impulsive tendencies. However, self-injurers have not been shown to be different from comparison groups on laboratory tasks putatively assessing impulsive behavior. One explanation for these contradictory findings is that self-report and laboratory measures of impulsive behavior tap into distinct but related constructs. Moreover, performance on laboratory measures of impulsive behavior can be influenced by myriad contextual and affective factors not present during past self-reported NSSI events. Accordingly, a relationship between behavioral tasks of impulsivity and self-injurious behavior could emerge if both are assessed relatively close in time under controlled laboratory conditions. To test this possibility, both self-ratings and laboratory task measures of self-injurious and impulsive behavior were employed in the current study. This multi-modal assessment approach revealed that self-rated impulsivity was associated with both self-report and behavioral measures of self-injurious behavior. Moreover, behavioral measures of impulsivity were associated with self-injurious behavior, but not NSSI history. These results provide support for the notion that a multi-modal approach to assessing self-injurious behavior is important for better understanding the correlates of nonsuicidal self-injury.

The primary goal of this study was to address the stability-despite-loss paradox of subjective well-being. Performance-based and self-evaluative measures of cognitive functioning were examined as predictors of subjective well-being in middle-aged and older adults using data from the Interdisciplinary Longitudinal Study of Adult Development (ILSE). Consistent with past work, subjective well-being remained relatively stable over a period of 12 years in both age groups, although performance-based and self-rated cognition declined over time. Cognitive status, as determined by standard psychometric tests of fluid cognitive abilities, was unrelated to longitudinal change in subjective well-being. A symmetrical measure of self-rated cognitive performance predicted intraindividual change in subjective well-being in middle-aged but not older adults. This pattern of findings helps clarify why many older people may be able to maintain their subjective well-being, while their cognitive abilities decline. (PsycINFO Database Record

Behavioral intervention technologies (BITs) are web-based and mobile interventions intended to support patients and consumers in changing behaviors related to health, mental health, and well-being. BITs are provided to patients and consumers in clinical care settings and commercial marketplaces, frequently with little or no evaluation. Current evaluation methods, including RCTs and implementation studies, can require years to validate an intervention. This timeline is fundamentally incompatible with the BIT environment, where technology advancement and changes in consumer expectations occur quickly, necessitating rapidly evolving interventions. However, BITs can routinely and iteratively collect data in a planned and strategic manner and generate evidence through systematic prospective analyses, thereby creating a system that can “learn.” A methodologic framework, Continuous Evaluation of Evolving Behavioral Intervention Technologies (CEEBIT), is proposed that can support the evaluation of multiple BITs or evolving versions, eliminating those that demonstrate poorer outcomes, while allowing new BITs to be entered at any time. CEEBIT could be used to ensure the effectiveness of BITs provided through deployment platforms in clinical care organizations or BIT marketplaces. The features of CEEBIT are described, including criteria for the determination of inferiority, determination of BIT inclusion, methods of assigning consumers to BITs, definition of outcomes, and evaluation of the usefulness of the system. CEEBIT offers the potential to collapse initial evaluation and postmarketing surveillance, providing ongoing assurance of safety and efficacy to patients and consumers, payers, and policymakers.

The cilium is a characteristic organelle of eukaryotes constructed from over 600 proteins. Bacterial flagella are entirely different. 9 + 2 motile cilia evolved before the divergence of the last eukaryotic common ancestor (LECA). This chapter explores, compares, and contrasts two potential pathways of evolution: (1) via invasion of a centriolar-like virus and (2) via autogenous formation from a pre-existing microtubule-organizing center (MTOC). In either case, the intraflagellar transport (IFT) machinery that is nearly universally required for the assembly and maintenance of cilia derived from the evolving intracellular vesicular transport system. The sensory function of cilia evolved first and the ciliary axoneme evolved gradually with ciliary motility, an important selection mechanism, as one of the driving forces.

The hypothesis that evolvability - the capacity to evolve by natural selection - is itself the object of natural selection is highly intriguing but remains controversial due in large part to a paucity of direct experimental evidence. The antigenic variation mechanisms of microbial pathogens provide an experimentally tractable system to test whether natural selection has favored mechanisms that increase evolvability. Many antigenic variation systems consist of paralogous unexpressed 'cassettes' that recombine into an expression site to rapidly alter the expressed protein. Importantly, the magnitude of antigenic change is a function of the genetic diversity among the unexpressed cassettes. Thus, evidence that selection favors among-cassette diversity is direct evidence that natural selection promotes antigenic evolvability. We used the Lyme disease bacterium, Borrelia burgdorferi, as a model to test the prediction that natural selection favors amino acid diversity among unexpressed vls cassettes and thereby promotes evolvability in a primary surface antigen, VlsE. The hypothesis that diversity among vls cassettes is favored by natural selection was supported in each B. burgdorferi strain analyzed using both classical (dN/dS ratios) and Bayesian population genetic analyses of genetic sequence data. This hypothesis was also supported by the conservation of highly mutable tandem-repeat structures across B. burgdorferi strains despite a near complete absence of sequence conservation. Diversification among vls cassettes due to natural selection and mutable repeat structures promotes long-term antigenic evolvability of VlsE. These findings provide a direct demonstration that molecular mechanisms that enhance evolvability of surface antigens are an evolutionary adaptation. The molecular evolutionary processes identified here can serve as a model for the evolution of antigenic evolvability in many pathogens which utilize similar strategies to establish chronic infections.

Workers' health is a central theme in public health surveys, but the specificity of work activities should be considered. This study aimed to analyze the health of rural workers in Brazil that perform both agricultural and non-agricultural work, based on self-rated health and self-reported diseases. The Brazilian National Household Sample Survey (PNAD 2008) was used, incorporating information from the complex sampling plan. Agricultural workers 18 years or older were selected, stratified according to those with and without non-agricultural work. Logistic regression was performed for self-rated health, and odds ratios were calculated for self-reported diseases. Exclusive agricultural work decreased the odds of reporting good health and increased the odds of reporting back pain, high blood pressure, and arthritis/rheumatism. Exclusive agricultural workers reported more diseases and worse living conditions. Self-rated health was generally better in workers with non-agricultural occupations.

This paper contributes evidence documenting the continued decline in all-cause mortality and changes in the cause of death distribution over time in four developing country populations in Africa and Asia. We present levels and trends in age-specific mortality (all-cause and cause-specific) from four demographic surveillance sites: Agincourt (South Africa), Navrongo (Ghana) in Africa; Filabavi (Vietnam), Matlab (Bangladesh) in Asia. We model mortality using discrete time event history analysis. This study illustrates how data from INDEPTH Network centers can provide a comparative, longitudinal examination of mortality patterns and the epidemiological transition. Health care systems need to be reconfigured to deal simultaneously with continuing challenges of communicable disease and increasing incidence of non-communicable diseases that require long-term care. In populations with endemic HIV, long-term care of HIV patients on ART will add to the chronic care needs of the community. PMID:27304429

This study investigates the joint effect of office type (cell, shared room, open-plan, and flex) and personality, measured by the Big Five personality traits, on self-rated measures of distraction, job satisfaction, and job performance (measured by professional efficacy). Regression analyses with interactions between personality and office type were conducted on 1205 participants working in 5 organizations from both the private and public sectors. While few interactions were observed in the cases of professional efficacy and job satisfaction, several were observed between personality traits and office type on the level of distraction reported. Specifically, more emotionally stable participants reported lower distraction, particularly those working in flex offices. Both agreeableness and openness to experience were associated with higher levels of distraction among participants in open-plan compared to cell offices. PMID:27223898

We demonstrate how the need to cope with operational faults enables evolving circuits to find more fit solutions. The analysis of the results obtained in different experimental conditions indicates that, in absence of faults, evolution tends to select circuits that are small and have low phenotypic variability and evolvability. The need to face operation faults, instead, drives evolution toward the selection of larger circuits that are truly robust with respect to genetic variations and that have a greater level of phenotypic variability and evolvability. Overall our results indicate that the need to cope with operation faults leads to the selection of circuits that have a greater probability to generate better circuits as a result of genetic variation with respect to a control condition in which circuits are not subjected to faults.

The Indian pharmaceutical industry, like any other industry, has undergone significant change in the last decade. The role of a Medical advisor has always been of paramount importance in the pharmaceutical companies in India. On account of the evolving medical science and the competitive environment, the medical advisor's role is also increasingly becoming critical. In India, with changes in regulatory rules, safety surveillance, and concept of medical liaisons, the role of the medical advisor is evolving continuously and is further likely to evolve in the coming years in important areas like health economics, public private partnerships, and strategic planning.

We investigate the sensitivity of Boolean Networks (BNs) to mutations. We are interested in Boolean Networks as a model of Gene Regulatory Networks (GRNs). We adopt Ribeiro and Kauffman’s Ergodic Set and use it to study the long term dynamics of a BN. We define the sensitivity of a BN to be the mean change in its Ergodic Set structure under all possible loss of interaction mutations. Insilico experiments were used to selectively evolve BNs for sensitivity to losing interactions. We find that maximum sensitivity was often achievable and resulted in the BNs becoming topologically balanced, i.e. they evolve towards network structures in which they have a similar number of inhibitory and excitatory interactions. In terms of the dynamics, the dominant sensitivity strategy that evolved was to build BNs with Ergodic Sets dominated by a single long limit cycle which is easily destabilised by mutations. We discuss the relevance of our findings in the context of Stem Cell Differentiation and propose a relationship between pluripotent stem cells and our evolved sensitive networks. PMID:22586459

The Thermal and Evolved Gas Analyzer (TEGA) instrument will perform calorimetry and evolved gas analysis on soil samples collected from the Martian surface. TEGA is one of three instruments, along with a robotic arm, that form the Mars Volatile and Climate Survey (MVACS) payload. The other instruments are a stereo surface imager, built by Peter Smith of the University of Arizona and a meteorological station, built by JPL. The MVACS lander will investigate a Martian landing site at approximately 70 deg south latitude. Launch will take place from Kennedy Space Center in January, 1999. The TEGA project started in February, 1996. In the intervening 24 months, a flight instrument concept has been designed, prototyped, built as an engineering model and flight model, and tested. The instrument performs laboratory-quality differential-scanning calorimetry (DSC) over the temperature range of Mars ambient to 1400K. Low-temperature volatiles (water and carbon dioxide ices) and the carbonates will be analyzed in this temperature range. Carbonates melt and evolve carbon dioxide at temperatures above 600 C. Evolved oxygen (down to a concentration of 1 ppm) is detected, and C02 and water vapor and the isotopic variations of C02 and water vapor are detected and their concentrations measured. The isotopic composition provides important tests of the theory of solar system formation.

In many different cell types proper polarization is essential for cell function. Polarization mechanisms however, differ between cell types and even closely related species use a variety of polarization machines. Budding yeast, for example, depends on several parallel mechanisms to establish polarity. One mechanism (i) depends on reaction and diffusion of proteins in the membrane. Another one (ii) depends on reorganization of the actin cytoskeleton. So why does yeast use several mechanisms simultaneously? Can yeast also polarize robustly in the absence of one of them? We addressed these questions by evolving budding yeast in the absence of mechanism (i) or (ii). We deleted a mechanism by deleting one or two genes that are essential for its function. After the deletion of either mechanism the growth rate of cells was highly decreased (2-5 fold) and their cell shape was highly perturbed. Subsequently, we evolved these cells for 10 days. Surprisingly, the evolved cells rapidly overcame most of their polarity defects. They grow at 0.9x wildtype growth rate and their cell shape is signifigantly less perturbed. Now we will study how these cells rescued polarization. Did they fix the deleted mechanism, strengthen other mechanisms or evolve a completely new one?

Measurement invariance is a prerequisite for comparing measurement scores from different groups. In medical education, multi-source feedback (MSF) is utilized to assess core competencies, including the professionalism. However, little attention has been paid to the measurement invariance of assessment instruments; that is, whether an instrument holds the same meaning across different rater groups. To examine the measurement invariance of the National Taiwan University professionalism MSF (NTU P-MSF) in order to determine whether medical students' self-rating can be compared to their peers' rating. An eight-factor model was specified for confirmatory factor analysis to examine the construct validity of the NTU P-MSF. Cronbach's alpha was computed for the items of each domain to evaluate internal consistent reliability. The same eight-factor model was used for multi-group confirmatory factor analyses. Four hierarchical models were specified to test configural (i.e., identical factor-item relationship), metric (i.e., identical factor loadings), scalar (i.e., identical intercepts), and error variance across self-rating and peer rating groups. One hundred and twenty second-year medical students from weekly discussion groups conducted as part of a medical professionalism course agreed to use the NTU P-MSF to assess themselves or their discussion group peers. NTU P-MSF assessment scores were a good fit for the eight-factor model among self group and peer group. The Cronbach's alpha coefficients of students' NTU P-MSF scores and peers' scores ranged from 0.76 to 0.89 and 0.84 to 0.91, respectively indicating that the NTU P-MSF scores also have good internal consistent reliability between both groups. In addition, same factor structure and similar factor loadings and intercepts of NTU P-MSF scores between both groups indicate that NTU P-MSF scores had configural, metric, and scalar invariance. Thus, students' self-assessments and peer assessments can be compared in terms of

Firstly, this paper proposes a non-uniform evolving hypergraph model with nonlinear preferential attachment and an attractiveness. This model allows nodes to arrive in batches according to a Poisson process and to form hyperedges with existing batches of nodes. Both the number of arriving nodes and that of chosen existing nodes are random variables so that the size of each hyperedge is non-uniform. This paper establishes the characteristic equation of hyperdegrees, calculates changes in the hyperdegree of each node, and obtains the stationary average hyperdegree distribution of the model by employing the Poisson process theory and the characteristic equation. Secondly, this paper constructs a model for weighted evolving hypergraphs that couples the establishment of new hyperedges, nodes and the dynamical evolution of the weights. Furthermore, what is obtained are respectively the stationary average hyperdegree and hyperstrength distributions by using the hyperdegree distribution of the established unweighted model above so that the weighted evolving hypergraph exhibits a scale-free behavior for both hyperdegree and hyperstrength distributions.

Separate literatures have related volunteering to health gains and income gains. We study the association between volunteering, income and health within one statistical framework. A state-of-the-art mediation analysis is conducted on data concerning the health, volunteering and sociodemographic characteristics of 42926 individuals within 29 European countries. We find that volunteering is positively associated to self-rated health. This association is partially mediated by household income. PMID:28273163

Autism is usually defined by impairments in the social domain but has also been linked to deficient dorsal visual stream processing. However, inconsistent findings make the nature of this relationship unclear and thus, we examined the role of stimulus-driven transient attention, presumably activated by the dorsal stream in autistic tendency. Contrast thresholds for object discrimination were compared between groups with high and low self-rated autistic tendency utilizing the socially based Autism Spectrum Quotient (AQ). Visual stimuli were presented with either abrupt or with ramped contrast onsets/offsets in order to manipulate the demands of transient attention. Larger impairments in performance of abrupt compared with ramped object presentation were established in the high AQ group. Furthermore, self-reported social skills predicted abrupt task performance, suggesting an important visual perception deficiency in autism-related traits. Autism spectrum disorder may be associated with reduced utilization of the dorsal stream to rapidly activate attention prior to ventral stream processing when stimuli are transient.

This on-road field investigation employed, for the first time, a completely automated trigger-based data collection system capable of evaluating driver performance in an extended-duration real-world commercial motor vehicle environment. The study examined the use of self-assessment of fatigue (Karolinska Sleepiness Scale) and temporal separation (minimum time to collision, minimum headway, and mean headway) as indicators of driver fatigue. Without exception, the correlation analyses for both the self-rating of alertness and temporal separation yielded models low in associative ability; neither metric was found to be a valid indicator of driver fatigue. In addition, based upon the data collected for this research, preliminary evidence suggests that driver fatigue onset within a real-world driving environment does not appear to follow the standard progression of events associated with the onset of fatigue within a simulated driving environment. Application of this research includes the development of an on-board driver performance/fatigue monitoring system that could potentially assist drivers in identifying the onset of fatigue.

This study aimed to assess patient's capacity to perform a patient-reported outcome (PRO) measure (i.e., a self-rating scale) and examine its relationship with clinical characteristics including cognition. Fifty patients with schizophrenia were asked to rate the Subjective Well-being under Neuroleptics scale - Short form (SWNS) twice; the second rating was started immediately after they completed the first to minimize the gap between ratings. At the same time, the Positive and Negative Symptoms Scale (PANSS) and Brief Neurocognitive Assessment (BNA) were administered. The correlations between the two ratings for the SWNS total and each item scores were high (rs=0.94 and rs=0.60-0.84, respectively); however, for 16 (80%) of 20 items, 5 or more patients (i.e., ≥10%) demonstrated a>1 point score difference. There was no significant correlation between the SWNS total score difference and any clinical characteristics including age, education duration, illness duration, antipsychotic dose, psychopathology, and cognition. In contrast, the number of items with a>1 point score difference was significantly correlated with disorganized symptoms and overall severity (rs=0.29 for both), as well as working memory and global cognition (rs=-0.41 and rs=-0.40, respectively). These findings suggest that PROs should be interpreted with caution in patients with schizophrenia with prominent disorganization and cognitive impairment.

In this work we study coupled oscillators on evolving networks. We find that the steady state behavior of the system is governed by the relative values of the spread in natural frequencies and the global coupling strength. For coupling strong in comparison to the spread in frequencies, the system of oscillators synchronize and when coupling strength and spread in frequencies are large, a phenomenon similar to amplitude death is observed. The network evolution provides a mechanism to build inter-oscillator connections and once a dynamic equilibrium is achieved, oscillators evolve according to their local interactions. We also find that the steady state properties change by the presence of additional time scales. We demonstrate these results based on numerical calculations studying dynamical evolution of limit-cycle and van der Pol oscillators.

We propose a new framework called Evolving Systems to describe the self-assembly, or autonomous assembly, of actively controlled dynamical subsystems into an Evolved System with a higher purpose. An introduction to Evolving Systems and exploration of the essential topics of the control and stability properties of Evolving Systems is provided. This chapter defines a framework for Evolving Systems, develops theory and control solutions for fundamental characteristics of Evolving Systems, and provides illustrative examples of Evolving Systems and their control with adaptive key component controllers.
Is there a difference between child self-ratings and parent proxy-ratings of the quality of life of children with a diagnosis of attention-deficit hyperactivity disorder (ADHD)? A systematic review of the literature.
Galloway, Helen; Newman, Emily
There are contemporary indicators that parent proxy-ratings and child self-ratings of a child's quality of life (QoL) are not interchangeable. This review examines dual informant studies to assess parent-child agreement on the QoL of children with attention-deficit/hyperactivity disorder. A systematic search of four major databases (PsycINFO, MEDLINE, EMBASE and Cochrane databases) was completed, and related peer-reviewed journals were hand-searched. Studies which reported quantitative QoL ratings for matched parent and child dyads were screened in accordance with relevant inclusion and exclusion criteria. Key findings were extracted from thirteen relevant studies, which were rated for conformity to the recommendations of an adapted version of the STROBE statement guidelines for observational studies. In the majority of studies reviewed, children rated their QoL more highly than their parents. There was some evidence for greater agreement on the physical health domain than psychosocial domains.

Background and Aims The pseudometallophyte Noccaea caerulescens is an excellent model to study evolutionary processes, as it grows both on normal and on heavy-metal-rich, toxic soils. The evolution and demography of populations are critically impacted by mating system and, yet, information about the N. caerulescens mating system is limited. Methods Mean selfing rates were assessed using microsatellite loci and a robust estimation method (RMES) in five metallicolous and five non-metallicolous populations of N. caerulescens in Southern France, and this measure was replicated for two successive reproductive seasons. As a part of the study, the patterns of gene flow among populations were analysed. The mating system was then characterized at a fine spatial scale in three populations using the MLTR method on progeny arrays. Key Results The results confirm that N. caerulescens has a mixed mating system, with selfing rates ranging from 0·2 to 0·5. Selfing rates did not vary much among populations within ecotypes, but were lower in the metallicolous than in the non-metallicolous ecotype, in both seasons. Effective population size was also lower in non-metallicolous populations. Biparental inbreeding was null to moderate. Differentiation among populations was generally high, but neither ecotype nor isolation by distance explained it. Conclusions The consequences of higher selfing rates on adaptation are expected to be weak to moderate in non-metallicolous populations and they are expected to suffer less from inbreeding depression, compared to metallicolous populations.

Although data are mixed, asthma and rheumatologic conditions may be associated with cognitive impairment. Medications may play a role because corticosteroids are associated with memory impairment. Therefore, an easily administered assessment of cognition would be useful in these patients. We assessed relationships between self-rated and clinician-rated cognitive performance and mood in patients with asthma and rheumatologic diseases. Participants included 31adults treated for asthma or rheumatologic disorders (17 receiving chronic prednisone therapy, and 14 not receiving prednisone). An objective assessment of a variety of cognitive domains was administered through clinician and patient-rated assessments of cognition. Composite scores for the objective (Global Clinical Rating [GCR]) and subjective (Neuropsychological Impairment Scale: Global Measure of Impairment [GMI]) measures of cognition were derived. Depression was assessed with the 17-item Hamilton Rating Scale for Depression (HRSD-17). A linear regression was conducted with GMI scores as dependent variable and GCR, HRSD-17 scores, and prednisone-use status, as independent variables. Significant differences between prednisone-treated patients and other patients were observed on the GCR, GMI, and HRSD-17. In the regression analysis, HRSD-17 scores, but not GCR scores, significantly predicted GMI scores. Prednisone-treated patients had higher levels of depressive symptoms and subjective and objective cognitive deficits than those not taking prednisone. In the combined patient groups, subjective cognitive assessment was more strongly related to depressive symptoms than objective cognition. Findings suggest physicians should be aware of the potential for cognitive deficits in patients taking corticosteroids and, when appropriate, should consider the use of objective neurocognitive tests or neuropsychology consultation to better characterize its presence and severity.

Endodontics is a constantly developing field, with new instruments, preparation techniques and sealants competing with trusted and traditional approaches to tooth restoration. Thus general dental practitioners must question and understand the significance of these developments before adopting new practices. In view of this, the aim of this article, and the associated presentation at the 2013 British Dental Conference & Exhibition, is to provide an overview of endodontic methods and constantly evolving best practice. The presentation will review current preparation techniques, comparing rotary versus reciprocation, and question current trends in restoration of the endodontically treated tooth.

Antimicrobial therapy is a key component of modern medical practice and a cornerstone for the development of complex clinical interventions in critically ill patients. Unfortunately, the increasing problem of antimicrobial resistance is now recognized as a major public health threat jeopardizing the care of thousands of patients worldwide. Gram-positive pathogens exhibit an immense genetic repertoire to adapt and develop resistance to virtually all antimicrobials clinically available. As more molecules become available to treat resistant gram-positive infections, resistance emerges as an evolutionary response. Thus, antimicrobial resistance has to be envisaged as an evolving phenomenon that demands constant surveillance and continuous efforts to identify emerging mechanisms of resistance to optimize the use of antibiotics and create strategies to circumvent this problem. Here, we will provide a broad perspective on the clinical aspects of antibiotic resistance in relevant gram-positive pathogens with emphasis on the mechanistic strategies used by these organisms to avoid being killed by commonly used antimicrobial agents.

Design and implementation of robust network modules is essential for construction of complex biological systems through hierarchical assembly of ‘parts’ and ‘devices’. The robustness of gene regulatory networks (GRNs) is ascribed chiefly to the underlying topology. The automatic designing capability of GRN topology that can exhibit robust behavior can dramatically change the current practice in synthetic biology. A recent study shows that Darwinian evolution can gradually develop higher topological robustness. Subsequently, this work presents an evolutionary algorithm that simulates natural evolution in silico, for identifying network topologies that are robust to perturbations. We present a Monte Carlo based method for quantifying topological robustness and designed a fitness approximation approach for efficient calculation of topological robustness which is computationally very intensive. The proposed framework was verified using two classic GRN behaviors: oscillation and bistability, although the framework is generalized for evolving other types of responses. The algorithm identified robust GRN architectures which were verified using different analysis and comparison. Analysis of the results also shed light on the relationship among robustness, cooperativity and complexity. This study also shows that nature has already evolved very robust architectures for its crucial systems; hence simulation of this natural process can be very valuable for designing robust biological systems.

The time process of transport on randomly evolving trees is investigated. By introducing the notions of living and dead nodes, a model of random tree evolution is constructed which describes the spreading in time of objects corresponding to nodes. It is assumed that at t=0 the tree consists of a single living node (root), from which the evolution may begin. At a certain time instant τ⩾0 , the root produces ν⩾0 living nodes connected by lines to the root which becomes dead at the moment of the offspring production. In the evolution process each of the new living nodes evolves further like a root independently of the others. By using the methods of the age-dependent branching processes we derive the joint distribution function of the numbers of living and dead nodes, and determine the correlation between these node numbers as a function of time. It is proved that the correlation function converges to 3/2 independently of the distributions of ν and τ when q1→1 and t→∞ . Also analyzed are the stochastic properties of the end nodes; and the correlation between the numbers of living and dead end nodes is shown to change its character suddenly at the very beginning of the evolution process. The survival probability of random trees is investigated and expressions are derived for this probability.

We present an approach for engineering evolving DNA barcodes in living cells. A homing guide RNA (hgRNA) scaffold directs the Cas9-hgRNA complex to the DNA locus of the hgRNA itself. We show that this homing CRISPR-Cas9 system acts as an expressed genetic barcode that diversifies its sequence and that the rate of diversification can be controlled in cultured cells. We further evaluate these barcodes in cell populations and show that they can be used to record lineage history and that the barcode RNA can be amplified in situ, a prerequisite for in situ sequencing. This integrated approach will have wide-ranging applications, such as in deep lineage tracing, cellular barcoding, molecular recording, dissecting cancer biology, and connectome mapping.

The Gleason grading system for prostate adenocarcinoma has evolved from its original scheme established in the 1960s-1970s, to a significantly modified system after two major consensus meetings conducted by the International Society of Urologic Pathology (ISUP) in 2005 and 2014, respectively. The Gleason grading system has been incorporated into the WHO classification of prostate cancer, the AJCC/UICC staging system, and the NCCN guidelines as one of the key factors in treatment decision. Both pathologists and clinicians need to fully understand the principles and practice of this grading system. We here briefly review the historical aspects of the original scheme and the recent developments of Gleason grading system, focusing on major changes over the years that resulted in the modern Gleason grading system, which has led to a new "Grade Group" system proposed by the 2014 ISUP consensus, and adopted by the 2016 WHO classification of tumours of the prostate.
Treatment modalities for heart diseases have considerable evolved during the last 20 years. Coronary and valvular heart disease are treated increasingly by less invasive percutaneous catheter based procedures instead of open-heart surgery. In addition, new cutting-edge interventions allow to cure heart disease for which until recently only medical treatment options were available. Whilst many patients benefit from these innovative therapies, rapidly developing technologies potentially carry the risk of overtreatment. In order to select patients for the most appropriate treatment, an intensive interdisciplinary teamwork between cardiologists and cardiac surgeons is a mandatory requirement. Additionally, knowledge transfer between cardiologists, their growing subspecialties and practitioners should be encouraged. Finally, timely scientific evaluation of new therapies and subsequent incorporation in guidelines remains crucial.

Precise measurements of the chemical, elemental, and isotopic composition of planetary surface material and gases, and observed variations in these compositions, can contribute significantly to our knowledge of the source(s), ages, and evolution of solar system materials. The analyses discussed in this paper are mostly made by mass spectrometers or some other type of mass analyzer, and address three broad areas of interest: (1) atmospheric composition - isotopic, elemental, and molecular, (2) gases evolved from solids, and (3) solids. Current isotopic data on nine elements, mostly from in situ analysis, but also from meteorites and telescopic observations are summarized. Potential instruments for isotopic analysis of lunar, Martian, Venusian, Mercury, and Pluto surfaces, along with asteroid, cometary and icy satellites, surfaces are discussed.

We propose a model for evolving networks by merging building blocks represented as complete graphs, reminiscent of modules in biological system or communities in sociology. The model shows power-law degree distributions, power-law clustering spectra, and high average clustering coefficients independent of network size. The analytical solutions indicate that a degree exponent is determined by the ratio of the number of merging nodes to that of all nodes in the blocks, demonstrating that the exponent is tunable, and are also applicable when the blocks are classical networks such as Erdös-Rényi or regular graphs. Our model becomes the same model as the Barabási-Albert model under a specific condition.

Accepted 20 August 1996 AIM—To examine evolution of the physical characteristics of Marfan's syndrome throughout childhood. METHODS—40 children were ascertained during the development of a regional register for Marfan's syndrome. Evolution of the clinical characteristics was determined by repeat evaluation of 10 patients with sporadic Marfan's syndrome and 30 with a family history of the condition. DNA marker studies were used to facilitate diagnosis in those with the familial condition. RESULTS—Musculoskeletal features predominated and evolved throughout childhood. Gene tracking enabled early diagnosis in children with familial Marfan's syndrome. CONCLUSIONS—These observations may aid the clinical diagnosis of Marfan's syndrome in childhood, especially in those with the sporadic condition. Gene tracking has a role in the early diagnosis of familial Marfan's syndrome, allowing appropriate follow up and preventive care. PMID:9059160

Video-based consultation is the only telehealth service reimbursed by the Medicare Benefits Schedule in Australia, but the uptake of telehealth is still low and inconsistent. There is a clear need for the development of appropriate medical evidence to support implementation of telehealth services. With the ubiquitous use of mobile phones, mobile health becomes important in facilitating health services and impacting clinical outcomes anywhere.

Summary Reliance on self-rated health to proxy medical need can bias estimation of education-related inequity in healthcare utilization. We correct this bias both by instrumenting self-rated health with objective health indicators and by purging self-rated health of reporting heterogeneity that is identified from health vignettes. Using data on elderly Europeans, we find that instrumenting self-rated health shifts the distribution of visits to a doctor in the direction of inequality favouring the better educated. There is a further, and typically larger, shift in the same direction when correction is made for the tendency of the better educated to rate their health more negatively. PMID:21938140

This study describes the social networks of secondary school students in Moshi Municipality, and their association with self-rated risk of human immunodeficiency virus (HIV) infection. A cross-sectional analytical study was conducted among 300 students aged 15-24 years in 5 secondary schools in Moshi, Tanzania. Bonding networks were defined as social groupings of students participating in activities within the school, while bridging networks were groups that included students participating in social groupings from outside of the school environs. A structured questionnaire was used to ask about participation in bonding and bridging social networks and self-rated HIV risk behavior. More participants participated in bonding networks (72%) than in bridging networks (29%). Participation in bridging networks was greater among females (25%) than males (12%, p<.005). Of 300 participants, 88 (29%) were sexually experienced, and of these 62 (70%) considered themselves to be at low risk of HIV infection. Factors associated with self-rated risk of HIV included: type of school (p<.003), family structure (p<.008), being sexually experienced (p<.004), having had sex in the past three months (p<.009), having an extra sexual partner (p<.054) and non-condom use in last sexual intercourse (p<.001), but not the presence or type of social capital. The study found no association between bonding and bridging social networks on self-rated risk of HIV among study participants. However, sexually experienced participants rated themselves at low risk of HIV infection despite practicing unsafe sex. Efforts to raise adolescents' self-awareness of risk of HIV infection through life skills education and HIV/acquired immunodeficiency syndrome risk reduction strategies may be beneficial to students in this at-risk group.

When selecting a system from multiple candidates, the customer seeks the one that best meets his or her needs. Recently the desire for evolvable systems has become more important and engineers are striving to develop systems that accommodate this need. In response to this search for evolvability, we present a historical perspective on evolvability, propose a refined definition of evolvability, and develop a quantitative method for measuring this property. We address this quantitative methodology from both a theoretical and practical perspective. This quantitative model is then applied to the problem of evolving a lunar mission to a Mars mission as a case study.

Self-rated health is routinely used in research and practise among general populations. Older people, however, seem to change their health perceptions. To accurately understand these changed perceptions we therefore need to study the correlates of older people's self-ratings. We examined self-rated, nurse-rated and physician-rated health's association with common disabilities in older people (the geriatric giants), mortality hazard and life satisfaction. For this, we used an age-representative population of 501 participant aged 85 from a middle-sized city in the Netherlands: the Leiden 85-plus Study. Participants with severe cognitive dysfunction were excluded. Participants themselves provided health ratings, as well as a visiting physician and a research nurse. Visual acuity, hearing loss, mobility, stability, urinal and faecal incontinence, cognitive function and mood (depressive symptoms) were included as geriatric giants. Participants provided a score for life satisfaction and were followed up for vital status. Concordance of self-rated health with physician-rated (k = .3 [.0]) and nurse-rated health (k = .2 [.0]) was low. All three ratings were associated with the geriatric giants except for hearing loss (all p < 0.001). Associations were equal in strength, except for depressive symptoms, which showed a stronger association with self-rated health (.8 [.1] versus .4 [.1]). Self-rated health predicted mortality less well than the other ratings. Self-rated health related stronger to life satisfaction than physician's and nurse's ratings. We conclude that professionals' health ratings are more reflective of physical health whereas self-rated health reflects more the older person's mental health, but all three health ratings are useful in research.

Postmenopausal longevity may have evolved in our lineage when ancestral grandmothers subsidized their daughters' fertility by provisioning grandchildren, but the verbal hypothesis has lacked mathematical support until now. Here, we present a formal simulation in which life spans similar to those of modern chimpanzees lengthen into the modern human range as a consequence of grandmother effects. Greater longevity raises the chance of living through the fertile years but is opposed by costs that differ for the sexes. Our grandmother assumptions are restrictive. Only females who are no longer fertile themselves are eligible, and female fertility extends to age 45 years. Initially, there are very few eligible grandmothers and effects are small. Grandmothers can support only one dependent at a time and do not care selectively for their daughters' offspring. They must take the oldest juveniles still relying on mothers; and infants under the age of 2 years are never eligible for subsidy. Our model includes no assumptions about brains, learning or pair bonds. Grandmother effects alone are sufficient to propel the doubling of life spans in less than sixty thousand years.

Idiopathic pulmonary fibrosis (IPF) occurs predominantly in middle-aged and older adults and accounts for 20% to 30% of interstitial lung diseases. It is usually progressive, resulting in respiratory failure and death. Diagnostic criteria for IPF have evolved over the years, and IPF is currently defined as a disease characterized by the histopathologic pattern of usual interstitial pneumonia occurring in the absence of an identifiable cause of lung injury. Understanding of the pathogenesis of IPF has shifted away from chronic inflammation and toward dysregulated fibroproliferative repair in response to alveolar epithelial injury. Idiopathic pulmonary fibrosis is likely a heterogeneous disorder caused by various interactions between genetic components and environmental exposures. High-resolution computed tomography can be diagnostic in the presence of typical findings such as bilateral reticular opacities associated with traction bronchiectasis/bronchiolectasis in a predominantly basal and subpleural distribution, along with subpleural honeycombing. In other circumstances, a surgical lung biopsy may be needed. The clinical course of IPF can be unpredictable and may be punctuated by acute deteriorations (acute exacerbation). Although progress continues in unraveling the mechanisms of IPF, effective therapy has remained elusive. Thus, clinicians and patients need to reach informed decisions regarding management options including lung transplant. The findings in this review were based on a literature search of PubMed using the search terms idiopathic pulmonary fibrosis and usual interstitial pneumonia, limited to human studies in the English language published from January 1, 2000, through December 31, 2013, and supplemented by key references published before the year 2000.

Our understanding of the origins of new metabolic functions is based upon anecdotal genetic and biochemical evidence. Some auxotrophies can be suppressed by overexpressing substrate-ambiguous enzymes (i.e., those that catalyze the same chemical transformation on different substrates). Other enzymes exhibit weak but detectable catalytic promiscuity in vitro (i.e., they catalyze different transformations on similar substrates). Cells adapt to novel environments through the evolution of these secondary activities, but neither their chemical natures nor their frequencies of occurrence have been characterized en bloc. Here, we systematically identified multifunctional genes within the Escherichia coli genome. We screened 104 single-gene knockout strains and discovered that many (20%) of these auxotrophs were rescued by the overexpression of at least one noncognate E. coli gene. The deleted gene and its suppressor were generally unrelated, suggesting that promiscuity is a product of contingency. This genome-wide survey demonstrates that multifunctional genes are common and illustrates the mechanistic diversity by which their products enhance metabolic robustness and evolvability.

The flow of a geomorphic agent over a sediment bed creates patterns in the substrate composed of bedforms. Ice is no exception to this, organising soft sedimentary substrates into subglacial bedforms. As we are yet to fully observe their initiation and evolution beneath a contemporary ice mass, little is known about how patterns in subglacial bedforms develop. Here we study 36,222 drumlins, divided into 72 flowsets, left behind by the former British-Irish Ice sheet. These flowsets provide us with 'snapshots' of drumlin pattern development. The probability distribution functions of the size and shape metrics of drumlins within these flowsets were analysed to determine whether behaviour that is common of other patterned phenomena has occurred. Specifically, we ask whether drumlins i) are printed at a specific scale; ii) grow or shrink after they initiate; iii) stabilise at a specific size and shape; and iv) migrate. Our results indicate that drumlins initiate at a minimum size and spacing. After initiation, the log-normal distribution of drumlin size and shape metrics suggests that drumlins grow, or possibly shrink, as they develop. We find no evidence for stabilisation in drumlin length, supporting the idea of a subglacial bedform continuum. Drumlin migration is difficult to determine from the palaeo-record. However, there are some indications that a mixture of static and mobile drumlins occurs, which could potentially lead to collisions, cannibalisation and coarsening. Further images of modern drumlin fields evolving beneath ice are required to capture stages of drumlin pattern evolution.

A number of mechanisms, such as magnetic fields, (binary) companions and circumstellar disks have been suggested to be the cause of non-spherical PNe and in particular collimated outflows. This work investigates one of these mechanisms: the magnetic fields. While MHD simulations show that the fields can indeed be important, few observations of magnetic fields have been done so far. We used the VLBA to observe five evolved stars, with the goal of detecting the magnetic field by means of water maser polarization. The sample consists in four AGB stars (IK Tau, RT Vir, IRC+60370 and AP Lyn) and one pPN (OH231.8+4.2). In four of the five sources, several strong maser features were detected allowing us to measure the linear and/or circular polarization. Based on the circular polarization detections, we infer the strength of the component of the field along the line of sight to be between ~30 mG and ~330 mG in the water maser regions of these four sources. When extrapolated to the surface of the stars, the magnetic field strength would be between a few hundred mG and a few Gauss when assuming a toroidal field geometry and higher when assuming more complex magnetic fields. We conclude that the magnetic energy we derived in the water maser regions is higher than the thermal and kinetic energy, leading to the conclusion that, indeed, magnetic fields probably play an important role in shaping Planetary Nebulae.

One of the most exciting developments in astronomy in the last 15 years was the discovery of crystalline silicate stardust by the Short Wavelength Spectrometer (SWS) on board of ISO; discovery of the crystalline grains was indeed one of the biggest surprises of the ISO mission. Initially discovered around AGB stars (evolved stars in the range of 0.8 > M/M¤>8) at far-infrared (IR) wavelengths, crystalline silicates have since been seen in many astrophysical environments including young stellar objects (T Tauri and Herbig Ae/Be), comets and Ultra Luminous Infrared Galaxies. Low and intermediate mass stars (LIMS) comprise 95% of the contributors to the ISM, so study of the formation of crystalline silicates is critical to our understanding of the ISM, which is thought to be primarily amorphous (one would expect an almost exact match between the composition of AGB dust shells and the dust in the ISM). Whether the crystalline dust is merely undetectable or amorphized remains a mystery. The FORCAST instrument on SOFIA as well as the PACS instrument on Herschel will provide exciting observing opportunities for the further study of crystalline silicates.

We present a set of multi-scale interlinked algorithms to model the dynamics of evolving foams. These algorithms couple the key effects of macroscopic bubble rearrangement, thin film drainage, and membrane rupture. For each of the mechanisms, we construct consistent and accurate algorithms, and couple them together to work across the wide range of space and time scales that occur in foam dynamics. These algorithms include second order finite difference projection methods for computing incompressible fluid flow on the macroscale, second order finite element methods to solve thin film drainage equations in the lamellae and Plateau borders, multiphase Voronoi Implicit Interface Methods to track interconnected membrane boundaries and capture topological changes, and Lagrangian particle methods for conservative liquid redistribution during rearrangement and rupture. We derive a full set of numerical approximations that are coupled via interface jump conditions and flux boundary conditions, and show convergence for the individual mechanisms. We demonstrate our approach by computing a variety of foam dynamics, including coupled evolution of three-dimensional bubble clusters attached to an anchored membrane and collapse of a foam cluster.

Background The role of infection preventionists (IPs) is expanding in response to demands for quality and transparency in health care. Practice analyses and survey research have demonstrated that IPs spend a majority of their time on surveillance and are increasingly responsible for prevention activities and management; however, deeper qualitative aspects of the IP role have rarely been explored. Methods We conducted a qualitative content analysis of in-depth interviews with 19 IPs at hospitals throughout the United States to describe the current IP role, specifically the ways that IPs effect improvements and the facilitators and barriers they face. Results The narratives document that the IP role is evolving in response to recent changes in the health care landscape and reveal that this progression is associated with friction and uncertainty. Tensions inherent in the evolving role of the IP emerged from the interviews as 4 broad themes: (1) expanding responsibilities outstrip resources, (2) shifting role boundaries create uncertainty, (3) evolving mechanisms of influence involve trade-offs, and (4) the stress of constant change is compounded by chronic recurring challenges. Conclusion Advances in implementation science, data standardization, and training in leadership skills are needed to support IPs in their evolving role. PMID:23880116

Broad-band submillimeter observations of the thermal emission from evolved stars have been obtained with the United Kingdom Infrared Telescope on Mauna Kea, Hawaii. These observations, at an effective wavelength of 400 ..mu..m, provide the most direct method for estimating the mass loss rate in dust from these stars and also help to define the long-wavelength thermal spectrum of the dust envelopes. The mass loss rates in dust that we derive range from 10/sup -9/ to 10/sup -6/ M/sub sun/ yr/sup -1/ and are compared with mass loss rates derived from molecular line observations to estimate gas-to-dust ratios in outflowing envelopes. These values are found to be generally compatible with the interstellar gas-to-dust ratio of approx.100 if submillimeter emissivities appropriate to amorphous grain structures are assumed. Our analysis of the spectrum of IRC+10216 confirms previous suggestions that the grain emissivity varies as lambda/sup -1.2/ rather than as lambda/sup -2/ for 10

A new model for evolving Evolutionary Algorithms is proposed in this paper. The model is based on the Linear Genetic Programming (LGP) technique. Every LGP chromosome encodes an EA which is used for solving a particular problem. Several Evolutionary Algorithms for function optimization, the Traveling Salesman Problem and the Quadratic Assignment Problem are evolved by using the considered model. Numerical experiments show that the evolved Evolutionary Algorithms perform similarly and sometimes even better than standard approaches for several well-known benchmarking problems.

The Moon was thought to be completely anhydrous until indigenous water was found in lunar samples in 2008. This discovery raised two fundamental questions about the Moon: how much water is present in the bulk Moon and is water uniformly distributed in the lunar interior? To address these questions, I studied a suite of lunar samples rich in a chemical component called KREEP (K, Rare Earth Elements, P), all of which are incompatible elements. Water behaves as an incompatible element in magmas, so KREEP-rich lunar samples are potentially water rich. In this dissertation, I present the results of a petrologic study of KREEP-rich lunar rocks, measurements of their water contents and deuterium (D) to hydrogen (H) ratios (D/H), and examined where these rocks fit into our understanding of water in the Moon as a whole. We performed a study of highly evolved, KREEP-rich lunar rocks called felsites and determined that they contain quartz. Using cooling rates derived from quartz-Ti thermometry, we show the felsites originated at a minimum pressure of ˜1 kbar, corresponding to a minimum depth of 20-25 km in the lunar crust. We calculate that at that pressure water would have been soluble in the melt, indicating that degassing of H2O from the felsite parental melts was likely minimal and hydrogen isotopes in intrusive rocks are likely unfractionated. We then measured D/H in apatite in KREEP-rich intrusive rocks to clarify the solar system source of the Moon's water. When viewed in the context of other lunar D/H studies, our results indicate there are at least three distinctive reservoirs in the lunar interior, including an ultra-low D reservoir that could represent a primitive component in the Moon's interior. Furthermore, our measurements of residual glass in a KREEP basalt show that the KREEP basaltic magmas contained 10 times less water than the source of the Apollo 17 pyroclastic glass beads, indicating that, though wetter than previously thought, the concentration of

For decades, disparities in health have been well documented in the United States and regrettably, remain prevalent despite evidence and appeals for their elimination. Compared to the majority, racial and ethnic minorities continue to have poorer health status and health outcomes for most chronic conditions including diabetes, cardiovascular disease, cancer, and end-stage renal disease. Many factors, such as affordability, access, and diversity in the healthcare system, influence care and outcomes, creating challenges that make the task of eliminating health disparities and achieving health equity daunting and elusive. Novel strategies are needed to bring about much needed change in the complex and evolving United States health care system. Although not exhaustive, opportunities such as 1) developing standardized race measurements across health systems, 2) implementing effective interventions, 3) improving workforce diversity, 4) utilizing technological advances, and 5) adopting practices such as personalized medicine may serve as appropriate starting points for moving towards health equity. Over the past several decades, diversity in the U.S. population has increased significantly and is expected to increase exponentially in the near future. As the population becomes more diverse, it is important to recognize the possibilities of new and emerging disparities. It is imperative that steps are taken to eliminate the current gap in care and prevent new disparities from developing. Therefore, we present challenges and offer recommendations for facilitating the process of eliminating health disparities and achieving health equity across diverse populations. PMID:26802756

Objectives. We examined whether health literacy was associated with self-rated oral health status and whether the relationship was mediated by patient–dentist communication and dental care patterns. Methods. We tested a path model with data collected from 2 waves of telephone surveys (baseline, 2009–2010; follow-up, 2011) of individuals residing in 36 rural census tracts in northern Florida (final sample size n = 1799). Results. Higher levels of health literacy were associated with better self-rated oral health status (B = 0.091; P < .001). In addition, higher levels of health literacy were associated with better patient–dentist communication, which in turn corresponded with patterns of regular dental care and better self-rated oral health (B = 0.003; P = .01). Conclusions. Our study showed that, beyond the often-reported effects of gender, race, education, financial status, and access to dental care, it is also important to consider the influence of health literacy and quality of patient–dentist communication on oral health status. Improved patient–dentist communication is needed as an initial step in improving the population’s oral health. PMID:24832423
Pennebaker's expressive writing paradigm has helped to introduce the benefits of writing to health care. However, research in expressive writing has been largely dominated by an experimental and quantitative approach that does not take into account critical methodologies and approaches in health psychology, the increasingly complex ways in which creative writing is now being used in health care settings or recent research in the broader field of creative writing and personal development, health and well-being (developmental creative writing). This article contrasts expressive writing theories and methodologies with those evolving in the relatively new field of developmental creative writing. It investigates a number of theoretical and methodological problems with the expressive writing model and argues for a more critical approach to future research.

Objective To examine the association between behavioural factors and the risk of chronic conditions and 2-week prevalence. Design This was a cross-sectional survey. Setting The study was conducted in Zhongshan, China. Participants A multistage clustering sampling method was used to select a representative sample of residents from the household registration system between July and September 2011. The overall sample replacement rate was 9.4%, and the final sample included 43 028 individuals. Outcome measures Chronic conditions and 2-week prevalence. Results 4979 (11.6%) of the participants reported having at least one chronic condition, 1067 (2.5%) had two or more concurrent chronic conditions, and 6830 (15.9%) reported having at least one disease in a 2-week recall period. The most common chronic condition was primary hypertension, which was reported by 6.8% of participants. Logistic regression models demonstrated that the main factors for having a chronic condition and 2-week prevalence were older age (≥65 years of age; OR 44.91, 95% CI 33.05 to 61.03; and OR 12.71, 95% CI 10.44 to 15.46, respectively), obesity (OR 3.00, 95% CI 2.63 to 3.42; and OR 2.50, 95% CI 2.22 to 2.82, respectively) and being a former smoker (OR 3.02, 95% CI 2.54 to 3.58; and OR 3.24, 95% CI 2.74 to 3.82, respectively). Conclusions This study suggests that older age, obesity and unhealthy behaviours are high-risk factors for poorer health status among the residents of Zhongshan, China. The present findings highlight the importance of recognising and managing harmful behaviours in order to improve health. PMID:26560055

Prey that are unprofitable to attack are typically conspicuous in appearance. Conventional theory assumes that these warning signals have evolved in response to predator receiver biases. However, such biases might be a symptom rather than a cause of warning signals. We therefore examine an alternative theory: that conspicuousness evolves in unprofitable prey to avoid confusion with profitable prey. One might wonder why unprofitable prey do not find a cryptic means to be distinct from profitable prey, reducing both their risk of confusion with profitable prey and their rate of detection by predators. Here we present the first coevolutionary model to allow for Batesian mimicry and signals with different levels of detectability. We find that unprofitable prey do indeed evolve ways of distinguishing themselves using cryptic signals, particularly when appearance traits can evolve in multiple dimensions. However, conspicuous warning signals readily evolve in unprofitable prey when there are more ways to look different from the background than to match it. Moreover, the more unprofitable the prey species, the higher its evolved conspicuousness. Our results provide strong support for the argument that unprofitable species evolve conspicuous signals to avoid confusion with profitable prey and indicate that peak shift in conspicuousness-linked traits is a major factor in its establishment.

Environments equipped with intelligent sensors can be of much help if they can recognize the actions or activities of their users. If this activity recognition is done automatically, it can be very useful for different tasks such as future action prediction, remote health monitoring, or interventions. Although there are several approaches for recognizing activities, most of them do not consider the changes in how a human performs a specific activity. We present an automated approach to recognize daily activities from the sensor readings of an intelligent home environment. However, as the way to perform an activity is usually not fixed but it changes and evolves, we propose an activity recognition method based on Evolving Fuzzy Systems.

The concept of the primary health-care team involving an increasingly diverse range of health care professionals is widely recognized as central to the pursuit of a primary care-led health service in the UK. Although GPs are formally recognized as the team leaders, there is little by way of policy prescription as to how team roles and relationships should be developed, or evidence as to how their roles have in fact evolved. Thus the notion of the primary health-care team while commonly employed, is in reality lacking definition with the current contribution of practice managers to the operation of this team being poorly understood. Focusing on the career backgrounds of practice managers, their range of responsibilities, and their involvement in innovation in general practice, presents a preliminary account of a chief scientist office-funded project examining the role being played by practice managers in primary health-care innovation. More specifically, utilizing data gained from the ongoing study, contextualizes the role played by practice managers in the primary health-care team. By exploring the business environment surrounding the NHS general practice, the research seeks to understand the evolving world of the practice manager. Drawing on questionnaire data, reinforced by qualitative data from the current interview phase, describes the role played by practice managers in differing practice contexts. This facilitates a discussion of a set of ideal type general practice organizational and managerial structures. Discusses the relationships and skills required by practice managers in each of these organizational types with reference to data gathered to date in the research.
Background A parental/family history of poor oral health may influence the oral-health-related quality of life (OHRQOL) of adults. Objectives To determine whether the oral health of mothers of young children can predict the OHRQOL of those same children when they reach adulthood. Methods Oral examination and interview data from the Dunedin Study's age-32 assessment, as well as maternal self-rated oral health data from the age-5 assessment were used. The main outcome measure was study members' short-form Oral Health Impact Profile (OHIP-14) at age 32. Analyses involved 827 individuals (81.5% of the surviving cohort) dentally examined at both ages, who also completed the OHIP-14 questionnaire at age 32, and whose mothers were interviewed at the age-5 assessment. Results There was a consistent gradient of relative risk across the categories of maternal self-rated oral health status at the age-5 assessment for having one or more impacts in the overall OHIP-14 scale, whereby risk was greatest among the study members whose mothers rated their oral health as "poor/edentulous", and lowest among those with an "excellent/fairly good" rating. In addition, there was a gradient in the age-32 mean OHIP-14 score, and in the mean number of OHIP-14 impacts at age 32 across the categories of maternal self-rated oral health status. The higher risk of having one or more impacts in the psychological discomfort subscale, when mother rated her oral health as "poor/edentulous", was statistically significant. Conclusions These data suggest that maternal self-rated oral health when a child is young has a bearing on that child's OHRQOL almost three decades later. The adult offspring of mothers with poor self-rated oral health had poorer OHRQOL outcomes, particularly in the psychological discomfort subscale. PMID:21736754

The epidemiology of foodborne disease is changing. New pathogens have emerged, and some have spread worldwide. Many, including Salmonella, Escherichia coli O157:H7, Campylobacter, and Yersinia enterocolitica, have reservoirs in healthy food animals, from which they spread to an increasing variety of foods. These pathogens cause millions of cases of sporadic illness and chronic complications, as well as large and challenging outbreaks over many states and nations. Improved surveillance that combines rapid subtyping methods, cluster identification, and collaborative epidemiologic investigation can identify and halt large, dispersed outbreaks. Outbreak investigations and case-control studies of sporadic cases can identify sources of infection and guide the development of specific prevention strategies. Better understanding of how pathogens persist in animal reservoirs is also critical to successful long-term prevention. In the past, the central challenge of foodborne disease lay in preventing the contamination of human food with sewage or animal manure. In the future, prevention of foodborne disease will increasingly depend on controlling contamination of feed and water consumed by the animals themselves. PMID:9366593

The authors introduce a quantitative measure of the capacity of a small biological network to evolve. The measure is applied to a stochastic description of the experimental setup of Guet et al. (Science 2002, 296, pp. 1466), treating chemical inducers as functional inputs to biochemical networks and the expression of a reporter gene as the functional output. The authors take an information-theoretic approach, allowing the system to set parameters that optimise signal processing ability, thus enumerating each network's highest-fidelity functions. All networks studied are highly evolvable by the measure, meaning that change in function has little dependence on change in parameters. Moreover, each network's functions are connected by paths in the parameter space along which information is not significantly lowered, meaning a network may continuously change its functionality without completely losing it along the way. This property further underscores the evolvability of the networks.

Genetic algorithms usually use string or tree representations. We have developed a novel crossover operator for a directed and undirected graph representation, and used this operator to evolve molecules and circuits. Unlike strings or trees, a single point in the representation cannot divide every possible graph into two parts, because graphs may contain cycles. Thus, the crossover operator is non-trivial. A steady-state, tournament selection genetic algorithm code (JavaGenes) was written to implement and test the graph crossover operator. All runs were executed by cycle-scavagging on networked workstations using the Condor batch processing system. The JavaGenes code has evolved pharmaceutical drug molecules and simple digital circuits. Results to date suggest that JavaGenes can evolve moderate sized drug molecules and very small circuits in reasonable time. The algorithm has greater difficulty with somewhat larger circuits, suggesting that directed graphs (circuits) are more difficult to evolve than undirected graphs (molecules), although necessary differences in the crossover operator may also explain the results. In principle, JavaGenes should be able to evolve other graph-representable systems, such as transportation networks, metabolic pathways, and computer networks. However, large graphs evolve significantly slower than smaller graphs, presumably because the space-of-all-graphs explodes combinatorially with graph size. Since the representation strongly affects genetic algorithm performance, adding graphs to the evolutionary programmer's bag-of-tricks should be beneficial. Also, since graph evolution operates directly on the phenotype, the genotype-phenotype translation step, common in genetic algorithm work, is eliminated.

We formulate a Stefan problem on an evolving hypersurface and study the well posedness of weak solutions given L1 data. To do this, we first develop function spaces and results to handle equations on evolving surfaces in order to give a natural treatment of the problem. Then, we consider the existence of solutions for data; this is done by regularization of the nonlinearity. The regularized problem is solved by a fixed point theorem and then uniform estimates are obtained in order to pass to the limit. By using a duality method, we show continuous dependence, which allows us to extend the results to L1 data. PMID:26261364

The term "landrace" has generally been defined as a cultivated, genetically heterogeneous variety that has evolved in a certain ecogeographical area and is therefore adapted to the edaphic and climatic conditions and to its traditional management and uses. Despite being considered by many to be inalterable, landraces have been and are in a constant state of evolution as a result of natural and artificial selection. Many landraces have disappeared from cultivation but are preserved in gene banks. Using modern selection and breeding technology tools to shape these preserved landraces together with the ones that are still cultivated is a further step in their evolution in order to preserve their agricultural significance. Adapting historical landraces to present agricultural conditions using cutting-edge breeding technology represents a challenging opportunity to use them in a modern sustainable agriculture, as an immediate return on the investment is highly unlikely. Consequently, we propose a more inclusive definition of landraces, namely that they consist of cultivated varieties that have evolved and may continue evolving, using conventional or modern breeding techniques, in traditional or new agricultural environments within a defined ecogeographical area and under the influence of the local human culture. This includes adaptation of landraces to new management systems and the unconscious or conscious selection made by farmers or breeders using available technology. In this respect, a mixed selection system might be established in which farmers and other social agents develop evolved landraces from the variability generated by public entities.

Evolved lunar igneous lithologies, often referred to as the alkali suite, are a minor but important component of the lunar crust. These evolved samples are incompatible-element rich samples, and are, not surprisingly, most common in the Apollo sites in (or near) the incompatible-element rich region of the Moon known as the Procellarum KREEP Terrane (PKT). The most commonly occurring lithologies are granites (A12, A14, A15, A17), monzogabbro (A14, A15), alkali anorthosites (A12, A14), and KREEP basalts (A15, A17). The Feldspathic Highlands Terrane is not entirely devoid of evolved lithologies, and rare clasts of alkali gabbronorite and sodic ferrogabbro (SFG) have been identified in Apollo 16 station 11 breccias 67915 and 67016. Curiously, nearly all pristine evolved lithologies have been found as small clasts or soil particles, exceptions being KREEP basalts 15382/6 and granitic sample 12013 (which is itself a breccia). Here we reexamine the petrography and geochemistry of two SFG-like particles found in a survey of Apollo 16 2-4 mm particles from the Cayley Plains 62283,7-15 and 62243,10-3 (hereafter 7-15 and 10-3 respectively). We will compare these to previously reported SFG samples, including recent analyses on the type specimen of SFG from lunar breccia 67915.

Interoperability is a major focus of the quickly evolving world of Health IT. Easy, yet secure and confidential exchange of imaging exams and the associated reports must be a part of the solutions that are implemented. The availability of historical exams is essential in providing a quality interpretation and reducing inappropriate utilization of imaging services. Today, the exchange of imaging exams is most often achieved via a compact disc. We describe the virtues of this solution as well as challenges that have surfaced. Internet- and cloud-based technologies employed for many consumer services can provide a better solution. Vendors are making these solutions available. Standards for Internet-based exchange are emerging. Just as radiology converged on DICOM as a standard to store and view images, we need a common exchange standard. We will review the existing standards and how they are organized into useful workflows through Integrating the Healthcare Enterprise profiles. Integrating the Healthcare Enterprise and standards development processes are discussed. Health care and the domain of radiology must stay current with quickly evolving Internet standards. The successful use of the "cloud" will depend on both the technologies and the policies put into place around them, both of which we discuss. The radiology community must lead the way and provide a solution that works for radiologists and clinicians with use of the electronic medical record. We describe features we believe radiologists should consider when adding Internet-based exchange solutions to their practice.
Background Fragmentation of plant populations may affect mating patterns and female and male reproductive success. To improve understanding of fragmentation effects on plant reproduction, we investigated the pollen flow patterns in six adjacent local populations of Magnolia stellata, an insect-pollinated, threatened tree species in Japan, and assessed effects of maternal plant (genet) size, local genet density, population size and neighboring population size on female reproductive success (seed production rates), and effects of mating distance, paternal genet size, population size and separation of populations on male reproductive success. Results The seed production rate, i.e. the proportion of ovules that successfully turned into seeds, varied between 1.0 and 6.5%, and increased with increasing population size and neighboring population size, and with decreasing maternal genet size and local genet density. The selfing rate varied between 3.6 and 28.9%, and increased with increasing maternal genet size and with declining local genet density. Male reproductive success increased with increasing paternal genet size, and decreased with increasing mating distance and separation of population. Pollen flow between the populations was low (6.1%) and highly leptocurtic. Conclusions Our results indicate that habitat fragmentation, separation and reduced size of populations, affected mating patterns and reproductive success of M. stellata. Local competition for pollinators and plant display size were likely to alter the reproductive success. PMID:23517612

Respondents may answer sensitive questions differently depending on the mode of assessment (e.g., questionnaire, interview). The possibility of differences in these mode effects across groups is an important assessment consideration given the implications for test-score validity and bias. Although differences in mode effects are highly relevant to issues in clinical assessment, research is limited and generally fails to make use of psychometrically sound methods. The present research argues for greater attention to demographic differences in mode effects with regard to the assessment of psychopathology. Analyses of differences in mode effects in depression assessment are presented for gender, age, and education based on data from 440 community adults. Depression symptom ratings from a structured clinical interview were regressed on a self-report state depression composite score; analyses tested for differences of intercept and slope across gender, age, and education. Neither slope nor intercept differences were found for gender, but intercept differences were obtained for both age and level of education. These results indicate that younger and better educated respondents receive somewhat lower than expected ratings of depression in interviews, given their level of self-rated symptoms. These findings suggest that use of a single mode of assessment over- or underpredicts depression in certain participants. More generally, they demonstrate the value of multimethod assessment of psychopathology and justify further inquiry into mode-effect differences in clinical assessment. (PsycINFO Database Record

Asian Indians (AI) have a high risk of atherosclerotic cardiovascular disease. The study investigated associations between discrimination and (1) cardiovascular risk and (2) self-rated health among AI. Higher discrimination scores were hypothesized to relate to a higher cardiovascular risk score (CRS) and poorer self-rated health. Asian Indians (n = 757) recruited between 2010 and 2013 answered discrimination and self-reported health questions. The CRS (0–8 points) included body-mass index, systolic blood pressure, total cholesterol, and fasting blood glucose levels of AI. Multiple linear regression analyses were conducted to evaluate relationships between discrimination and the CRS and discrimination and self-rated health, adjusting for psychosocial and clinical factors. There were no significant relationships between discrimination and the CRS (p ≥ .05). Discrimination was related to poorer self-reported health, B = −.41 (SE = .17), p = .02. Findings suggest perhaps there are important levels at which discrimination may harm health. PMID:27039100

Secondary organic aerosols have been characterized by evolved gas analysis (EGA). Hydrocarbons selected as aerosol precursors were representative of anthropogenic emissions (cyclohexene, cyclopentene, 1-decene and 1-dodecene, n-dodecane, o-xylene, and 1,3,5-trimethylbenzene) and of biogenic emissions (the terpenes [alpha]-pinene, [beta]-pinene and d-limonene and the sesquiterpene trans-caryophyllene). Also analyzed by EGA were samples of secondary, primary (highway tunnel), and ambient (urban) aerosols before and after exposure to ozone and other photochemical oxidants. The major features of the EGA thermograms (amount of CO[sub 2] evolved as a function of temperature) are described. The usefulness and limitations of EGA data for source apportionment of atmospheric particulate carbon are briefly discussed. 28 refs., 7 figs., 4 tabs.

The effect of an evolving luminosity function (LF) on the ability of foreground galaxies to obscure background sources is discussed, using the Press-Schechter/CDM standard evolving LF model. Galaxies are modeled as simplified versions of local spirals and Poisson statistics are used to estimate the fraction of sky covered by intervening dusty galaxies and the mean optical depths due to these galaxies. The results are compared to those obtained in the case of nonevolving luminosity function in a low-density universe. It is found that evolution of the galaxy LF does not allow the quasar dust obscuration hypothesis to be sustained for dust disks with plausible sizes. Even in a low-density universe, where evolution at z = less than 10 is unimportant, large disk radii are needed to achieve the desired obscuring effect. The mean fraction of sky covered is presented as a function of the redshift z along with adequate diagram illustrations.

This paper discusses the problem of increased programming time for intrinsic evolvable hardware (EM) as the complexity of the circuit grows. As the circuit becomes more complex, then more components will be required and a longer programming string, L, is required. We develop equations for the size of the population, n, and the number of generations required for the population to converge, based on L. Our analytical results show that even though the design search space grows as 2L (assuming a binary programming string), the number of circuit evaluations, n*ngen, only grows as O(Lg3), or slightly less than O(L). This makes evolvable techniques a good tool for exploring large design spaces. The major hurdle for intrinsic EHW is evaluation time for each possible circuit. The evaluation time involves downloading the bit string to the device, updating the device configuration, measuring the output and then transferring the output data to the control processor. Each of these steps must be done for each member of the population. The processing time of the computer becomes negligible since the selection/crossover/mutation steps are only done once per generation. Evaluation time presently limits intrinsic evolvable hardware techniques to designing only small or medium-sized circuits. To evolve large or complicated circuits, several researchers have proposed using hierarchical design or reuse techniques where submodules are combined together to form complex circuits. However, these practical approaches limit the search space of available designs and preclude utilizing parasitic coupling or other effects within the programmable device. The practical approaches also raise the issue of why intrinsic EHW techniques do not easily apply to large design spaces, since the analytical results show only an O(L) complexity growth.
We study the advantages of quantum strategies in evolutionary social dilemmas on evolving random networks. We focus our study on the two-player games: prisoner's dilemma, snowdrift and stag-hunt games. The obtained result show the benefits of quantum strategies for the prisoner's dilemma game. For the other two games, we obtain regions of parameters where the quantum strategies dominate, as well as regions where the classical strategies coexist.

The Jet Propulsion Laboratory (JPL) performs research in fault tolerant, long life, and space survivable electronics for the National Aeronautics and Space Administration (NASA). With that focus, JPL has been involved in Evolvable Hardware (EHW) technology research for the past several years. We have advanced the technology not only by simulation and evolution experiments, but also by designing, fabricating, and evolving a variety of transistor-based analog and digital circuits at the chip level. EHW refers to self-configuration of electronic hardware by evolutionary/genetic search mechanisms, thereby maintaining existing functionality in the presence of degradations due to aging, temperature, and radiation. In addition, EHW has the capability to reconfigure itself for new functionality when required for mission changes or encountered opportunities. Evolution experiments are performed using a genetic algorithm running on a DSP as the reconfiguration mechanism and controlling the evolvable hardware mounted on a self-contained circuit board. Rapid reconfiguration allows convergence to circuit solutions in the order of seconds. The paper illustrates hardware evolution results of electronic circuits and their ability to perform under 230 C temperature as well as radiations of up to 250 kRad.

The diverse array of body plans possessed by arthropods is created by generating variations upon a design of repeated segments formed during development, using a relatively small "toolbox" of conserved patterning genes. These attributes make the arthropod body plan a valuable model for elucidating how changes in development create diversity of form. As increasingly specialized segments and appendages evolved in arthropods, the nervous systems of these animals also evolved to control the function of these structures. Although there is a remarkable degree of conservation in neural development both between individual segments in any given species and between the nervous systems of different arthropod groups, the differences that do exist are informative for inferring general principles about the holistic evolution of body plans. This review describes developmental processes controlling neural segmentation and regionalization, highlighting segmentation mechanisms that create both ectodermal and neural segments, as well as recent studies of the role of Hox genes in generating regional specification within the central nervous system. We argue that this system generates a modular design that allows the nervous system to evolve in concert with the body segments and their associated appendages. This information will be useful in future studies of macroevolutionary changes in arthropod body plans, especially in understanding how these transformations can be made in a way that retains the function of appendages during evolutionary transitions in morphology.

Crew health concerns for Space Station Freedom are numerous due to medical hazards from isolation and confinement, internal and external environments, zero gravity effects, occupational exposures, and possible endogenous medical events. The operational crew health program will evolve from existing programs and from life sciences investigations aboard Space Station Freedom to include medical monitoring and certification, medical intervention, health maintenance and countermeasures, psychosocial support, and environmental health monitoring. The knowledge and experience gained regarding crew health issues and needs aboard Space Station Freedom will be used not only to verify requirements and programs for long duration space flight, but also in planning and preparation for Lunar and Mars exploration and colonization.

Understanding of the definitions of wellness and illness has changed from the mid-20th century to modern times, moving from a diagnosis-focused to a person-focused definition of mental illnesses, and from an "absence of disease" model to one that stresses positive psychological function for mental health. Currently, wellness refers to the degree to which one feels positive and enthusiastic about oneself and life, whereas illness refers to the presence of disease. These definitions apply to physical as well as mental illness and wellness. In this article, we build on the essential concepts of wellness and illness, discuss how these definitions have changed over time, and discuss their importance in the context of health reform and health care reform. Health reform refers to efforts focused on health, such as health promotion and the development of positive well-being. Health care reform refers to efforts focused on illness, such as treatment of disease and related rehabilitation efforts.

Study objective: It is increasingly recognised that different dimensions of social inequality may be linked to health by different pathways. Furthermore, factors operating at the individual level such as employment conditions may affect health in a different way from household level factors. The paper examines the associations between self rated health and four measures of social position— occupational class, household social advantage, personal and household income. Design: Multilevel logistic regression models were used to predict self rated health using longitudinal data from the British Household panel survey (BHPS) with respondents nested within households. Separate analyses were carried out for economically active and inactive respondents. Setting: Interview based surveys of adults living within households that are representative of British households. Participants: Adult respondents from the BHPS. Main results: Occupational class has relatively strong effects on the self rated health of the economically active, although household level factors also seem to influence their health. Household social advantage has relatively strong effects on the self rated health of the economically inactive. Conclusions: The paper found evidence in support of the view that different dimensions of social inequality have different pathways to self rated health. There are unexplained similarities in health between household members, which require further investigation. PMID:12490650

This paper describes an evolutionary perspective on human development and wellbeing and contrasts it with the model of self-interest that is prominent in economics. The two approaches have considerably different implications for how human wellbeing might be improved. Research in psychology, prevention science, and neuroscience is converging on an evolutionary account of the importance of two contrasting suites of social behavior—prosociality vs. antisocial behaviors (crime, drug abuse, risky sexual behavior) and related problems such as depression. Prosociality of individuals and groups evolves in environments that minimize toxic biological and social conditions, promote and richly reinforce prosocial behavior and attitudes, limit opportunities for antisocial behavior, and nurture the pursuit of prosocial values. Conversely, antisocial behavior and related problems emerge in environments that are high in threat and conflict. Over the past 30 years, randomized trials have shown numerous family, school, and community interventions to prevent most problem behaviors and promote prosociality. Research has also shown that poverty and economic inequality are major risk factors for the development of problem behaviors. The paper describes policies that can reduce poverty and benefit youth development. Although it is clear that the canonical economic model of rational self-interest has made a significant contribution to the science of economics, the evidence reviewed here shows that it must be reconciled with an evolutionary perspective on human development and wellbeing if society is going to evolve public policies that advance the health and wellbeing of the entire population.

Rapidly changing technology coupled with the financial impact of organized health care, has required hospital Biomedical Engineering organizations to augment their traditional operational and business models to increase their role in developing enhanced clinical applications utilizing new and evolving technologies. The deployment of these technology based applications has required Biomedical Engineering organizations to re-organize to optimize the manner in which they provide and manage services. Memorial Sloan-Kettering Cancer Center has implemented a strategy to explore evolving technologies integrating them into enhanced clinical applications while optimally utilizing the expertise of the traditional Biomedical Engineering component (Clinical Engineering) to provide expanded support in technology / equipment management, device repair, preventive maintenance and integration with legacy clinical systems. Specifically, Biomedical Engineering is an integral component of the Medical Physics Department which provides comprehensive and integrated support to the Center in advanced physical, technical and engineering technology. This organizational structure emphasizes the integration and collaboration between a spectrum of technical expertise for clinical support and equipment management roles. The high cost of clinical equipment purchases coupled with the increasing cost of service has driven equipment management responsibilities to include significant business and financial aspects to provide a cost effective service model. This case study details the dynamics of these expanded roles, future initiatives and benefits for Biomedical Engineering and Memorial Sloan Kettering Cancer Center.

Physical processes that characterize living matter are qualitatively distinct in that they involve encoding and transfer of specific types of information. Such information plays an active part in the control of events that are ultimately linked to the capacity of the system to persist and multiply. This algorithmicity of life is a key prerequisite for its Darwinian evolution, driven by natural selection acting upon stochastically arising variations of the encoded information. The concept of evolvability attempts to define the total capacity of a system to evolve new encoded traits under appropriate conditions, i.e., the accessible section of total morphological space. Since this is dependent on previously evolved regulatory networks that govern information flow in the system, evolvability itself may be regarded as an evolved ability. The way information is physically written, read and modified in living cells (the "coding concept") has not changed substantially during the whole history of the Earth's biosphere. This biosphere, be it alone or one of many, is, accordingly, itself a product of natural selection, since the overall evolvability conferred by its coding concept (nucleic acids as information carriers with the "rulebook of meanings" provided by codons, as well as all the subsystems that regulate various conditional information-reading modes) certainly played a key role in enabling this biosphere to survive up to the present, through alterations of planetary conditions, including at least five catastrophic events linked to major mass extinctions. We submit that, whatever the actual prebiotic physical and chemical processes may have been on our home planet, or may, in principle, occur at some time and place in the Universe, a particular coding concept, with its respective potential to give rise to a biosphere, or class of biospheres, of a certain evolvability, may itself be regarded as a unit (indeed the arch-unit) of natural selection.

Many practical issues in medical ethics depend on an understanding of the concept of health. The main question is whether it is a purely descriptive or a partly evaluative or normative concept. After posing some puzzles about the concept, the views of C Boorse, who thinks it is descriptive, are discussed and difficulties are found for them. An evaluative treatment is then suggested, and used to shed light on some problems about mental illness and to compare and contrast it with physical illness and with political and other deviancies which are not illnesses.

Longstanding theory in behavioral ecology predicts that prey should evolve decreased foraging rates under high predation threat. However, an alternative perspective suggests that growth into a size refuge from gape-limited predation and the future benefits of large size can outweigh the initial survival costs of intense foraging. Here, I evaluate the relative contributions of selection from a gape-limited predator (Ambystoma opacum) and spatial location to explanations of variation in foraging, growth, and survival in 10 populations of salamander larvae (Ambystoma maculatum). Salamander larvae from populations naturally exposed to intense A. opacum predation risk foraged more actively under common garden conditions. Higher foraging rates were associated with low survival in populations exposed to free-ranging A. opacum larvae. Results demonstrate that risky foraging activity can evolve in high predation-risk habitats when the dominant predators are gape-limited. This finding invites the further exploration of diverse patterns of prey foraging behavior that depends on natural variation in predator size-selectivity. In particular, prey should adopt riskier behaviors under predation threat than expected under existing risk allocation models if foraging effort directly reduces the duration of risk by growth into a size refuge. Moreover, evidence from this study suggests that foraging has evolved over microgeographic scales despite substantial modification by regional gene flow. This interaction between local selection and spatial location suggests a joint role for adaptation and maladaptation in shaping species interactions across natural landscapes, which is a finding with implications for dynamics at the population, community, and metacommunity levels.

We consider a simple physical model for an evolving horizon that is strongly interacting with its environment, exchanging arbitrarily large quantities of matter with its environment in the form of both infalling material and outgoing Hawking radiation. We permit fluxes of both lightlike and timelike particles to cross the horizon, and ask how the horizon grows and shrinks in response to such flows. We place a premium on providing a clear and straightforward exposition with simple formulae. To be able to handle such a highly dynamical situation in a simple manner we make one significant physical restriction—that of spherical symmetry—and two technical mathematical restrictions: (1) we choose to slice the spacetime in such a way that the spacetime foliations (and hence the horizons) are always spherically symmetric. (2) Furthermore, we adopt Painlevé Gullstrand coordinates (which are well suited to the problem because they are nonsingular at the horizon) in order to simplify the relevant calculations. Of course physics results are ultimately independent of the choice of coordinates, but this particular coordinate system yields a clean physical interpretation of the relevant physics. We find particularly simple forms for surface gravity, and for the first and second law of black hole thermodynamics, in this general evolving horizon situation. Furthermore, we relate our results to Hawking's apparent horizon, Ashtekar and co-worker's isolated and dynamical horizons, and Hayward's trapping horizon. The evolving black hole model discussed here will be of interest, both from an astrophysical viewpoint in terms of discussing growing black holes and from a purely theoretical viewpoint in discussing black hole evaporation via Hawking radiation.

Wolf crater is an irregularly shaped, approximately 25 km crater in the south-central portion of Mare Nubium on the lunar nearside. While not previously identified as a lunar "red spot", Wolf crater was identified as a Th anomaly by Lawrence and coworkers. We have used data from the Lunar Reconnaissance Orbiter (LRO) to determine the area surrounding Wolf crater has composition more similar to highly evolved, non-mare volcanic structures than typical lunar crustal lithology. In this presentation, we will investigate the geomorphology and composition of the Wolf crater and discuss implications for the origin of the anomalous terrain.

The utilization of solar energy on a large scale requires efficient storage. Solar-to-fuels has the capacity to meet large scale storage needs as demonstrated by natural photosynthesis. This process uses sunlight to rearrange the bonds of water to furnish O2 and an H2-equivalent. We present a tutorial review of our efforts to develop an amorphous cobalt-phosphate catalyst that oxidizes water to O2. The use of earth-abundant materials, operation in water at neutral pH, and the formation of the catalyst in situ captures functional elements of the oxygen evolving complex of Photosystem II.

An evolvable circuit includes a plurality of reconfigurable switches, a plurality of transistors within a region of the circuit, the plurality of transistors having terminals, the plurality of transistors being coupled between a power source terminal and a power sink terminal so as to be capable of admitting power between the power source terminal and the power sink terminal, the plurality of transistors being coupled so that every transistor terminal to transistor terminal coupling within the region of the circuit comprises a reconfigurable switch.
The paradigm that the secretory pathway consists of a stable endoplasmic reticulum and Golgi apparatus, using discrete transport vesicles to exchange their contents, gained important support from groundbreaking biochemical and genetic studies during the 1980s. However, the subsequent development of new imaging technologies with green fluorescent protein introduced data on dynamic processes not fully accounted for by the paradigm. As a result, we may be seeing an example of how a paradigm is evolving to account for the results of new technologies and their new ways of describing cellular processes. PMID:22039065

Handheld devices are becoming more cost-effective to own, and their use in healthcare environments is increasing. Handheld devices currently are being used for e-prescribing, charge capture, and accessing daily schedules and reference tools. Future applications may include education on medications, dictation, order entry, and test-results reporting. Selecting the right handheld device requires careful analysis of current and future applications, as well as vendor expertise. It is important to recognize the technology will continue to evolve over the next three years.

Studies on the relationship between the optimal phenotype and its environment have had limited focus on genotype-to-phenotype pathways and their evolutionary consequences. Here, we study how multi-layered trait architecture and its associated constraints prescribe diversity. Using an idealized model of the emotion system in fish, we find that trait architecture yields genetic and phenotypic diversity even in absence of frequency-dependent selection or environmental variation. That is, for a given environment, phenotype frequency distributions are predictable while gene pools are not. The conservation of phenotypic traits among these genetically different populations is due to the multi-layered trait architecture, in which one adaptation at a higher architectural level can be achieved by several different adaptations at a lower level. Our results emphasize the role of convergent evolution and the organismal level of selection. While trait architecture makes individuals more constrained than what has been assumed in optimization theory, the resulting populations are genetically more diverse and adaptable. The emotion system in animals may thus have evolved by natural selection because it simultaneously enhances three important functions, the behavioural robustness of individuals, the evolvability of gene pools and the rate of evolutionary innovation at several architectural levels.

By definition fire prone ecosystems have highly combustible plants, leading to the hypothesis, first formally stated by Mutch in 1970, that community flammability is the product of natural selection of flammable traits. However, proving the “Mutch hypothesis” has presented an enormous challenge for fire ecologists given the difficulty in establishing cause and effect between landscape fire and flammable plant traits. Individual plant traits (such as leaf moisture content, retention of dead branches and foliage, oil rich foliage) are known to affect the flammability of plants but there is no evidence these characters evolved specifically to self-immolate, although some of these traits may have been secondarily modified to increase the propensity to burn. Demonstrating individual benefits from self-immolation is extraordinarily difficult, given the intersection of the physical environmental factors that control landscape fire (fuel production, dryness and ignitions) with community flammability properties that emerge from numerous traits of multiple species (canopy cover and litter bed bulk density). It is more parsimonious to conclude plants have evolved mechanisms to tolerate, but not promote, landscape fire. PMID:25414710

Evolution and maintenance of genetic recombination and its relation to the mutational process is a long-standing, fundamental problem in evolutionary biology that is linked to the general problem of evolution of evolvability. We explored a stochastic model of the evolution of recombination using additive fitness and infinite allele assumptions but no assumptions on the sign or magnitude of the epistasis and the distribution of mutation effects. In this model, fluctuating negative epistasis and predominantly deleterious mutations arise naturally as a consequence of the additive fitness and a reservoir from which new alleles arrive with a fixed distribution of fitness effects. Analysis of the model revealed a nonmonotonic effect of recombination intensity on fitness, with an optimal recombination rate value which maximized fitness in steady state. The optimal recombination rate depended on the mutation rate and was evolvable, that is, subject to selection. The predictions of the model were compatible with the observations on the dependence between genome rearrangement rate and gene flux in microbial genomes.

In a recent opinion piece, Denis Duboule has claimed that the increasing shift towards systems biology is driving evolutionary and developmental biology apart, and that a true reunification of these two disciplines within the framework of evolutionary developmental biology (EvoDevo) may easily take another 100 years. He identifies methodological, epistemological, and social differences as causes for this supposed separation. Our article provides a contrasting view. We argue that Duboule's prediction is based on a one-sided understanding of systems biology as a science that is only interested in functional, not evolutionary, aspects of biological processes. Instead, we propose a research program for an evolutionary systems biology, which is based on local exploration of the configuration space in evolving developmental systems. We call this approach-which is based on reverse engineering, simulation, and mathematical analysis-the natural history of configuration space. We discuss a number of illustrative examples that demonstrate the past success of local exploration, as opposed to global mapping, in different biological contexts. We argue that this pragmatic mode of inquiry can be extended and applied to the mathematical analysis of the developmental repertoire and evolutionary potential of evolving developmental mechanisms and that evolutionary systems biology so conceived provides a pragmatic epistemological framework for the EvoDevo synthesis.

Because of their small size and high reliability, microelectromechanical (MEMS) devices have the potential to revolution many areas of engineering. As with conventionally-sized engineering design, there is likely to be a demand for the automated design of MEMS devices. This paper describes our current status as we progress toward our ultimate goal of using an evolutionary algorithm and a generative representation to produce designs of a MEMS device and successfully demonstrate its transfer to an actual chip. To produce designs that are likely to transfer to reality, we present two ways to modify evaluation of designs. The first is to add location noise, differences between the actual dimensions of the design and the design blueprint, which is a technique we have used for our work in evolving antennas and robots. The second method is to add prestress to model the warping that occurs during the extreme heat of fabrication. In future we expect to fabricate and test some MEMS resonators that are evolved in this way.

Mechanisms for the formation of crust on planetary bodies remain poorly understood. It is generally accepted that Earth's andesitic continental crust is the product of plate tectonics, whereas the Moon acquired its feldspar-rich crust by way of plagioclase flotation in a magma ocean. Basaltic meteorites provide evidence that, like the terrestrial planets, some asteroids generated crust and underwent large-scale differentiation processes. Until now, however, no evolved felsic asteroidal crust has been sampled or observed. Here we report age and compositional data for the newly discovered, paired and differentiated meteorites Graves Nunatak (GRA) 06128 and GRA 06129. These meteorites are feldspar-rich, with andesite bulk compositions. Their age of 4.52 +/- 0.06 Gyr demonstrates formation early in Solar System history. The isotopic and elemental compositions, degree of metamorphic re-equilibration and sulphide-rich nature of the meteorites are most consistent with an origin as partial melts from a volatile-rich, oxidized asteroid. GRA 06128 and 06129 are the result of a newly recognized style of evolved crust formation, bearing witness to incomplete differentiation of their parent asteroid and to previously unrecognized diversity of early-formed materials in the Solar System.
Cooperation violates the view of "nature red in tooth and claw" that prevails in our understanding of evolution, yet examples of cooperation abound. Most work has focused on maintenance of cooperation within a single species through mechanisms such as kin selection. The factors necessary for the evolutionary origin of aiding unrelated individuals such as members of another species have not been experimentally tested. Here, I demonstrate that cooperation between species can be evolved in the laboratory if (1) there is preexisting reciprocation or feedback for cooperation, and (2) reciprocation is preferentially received by cooperative genotypes. I used a two species system involving Salmonella enterica ser. Typhimurium and an Escherichia coli mutant unable to synthesize an essential amino acid. In lactose media Salmonella consumes metabolic waste from E. coli, thus creating a mechanism of reciprocation for cooperation. Growth in a spatially structured environment assured that the benefits of cooperation were preferentially received by cooperative genotypes. Salmonella evolved to aid E. coli by excreting a costly amino acid, however this novel cooperation disappeared if the waste consumption or spatial structure were removed. This study builds on previous work to demonstrate an experimental origin of interspecific cooperation, and to test the factors necessary for such interactions to arise.

Game theory provides a quantitative framework for analyzing the behavior of rational agents. The Iterated Prisoner’s Dilemma in particular has become a standard model for studying cooperation and cheating, with cooperation often emerging as a robust outcome in evolving populations. Here we extend evolutionary game theory by allowing players’ payoffs as well as their strategies to evolve in response to selection on heritable mutations. In nature, many organisms engage in mutually beneficial interactions and individuals may seek to change the ratio of risk to reward for cooperation by altering the resources they commit to cooperative interactions. To study this, we construct a general framework for the coevolution of strategies and payoffs in arbitrary iterated games. We show that, when there is a tradeoff between the benefits and costs of cooperation, coevolution often leads to a dramatic loss of cooperation in the Iterated Prisoner’s Dilemma. The collapse of cooperation is so extreme that the average payoff in a population can decline even as the potential reward for mutual cooperation increases. Depending upon the form of tradeoffs, evolution may even move away from the Iterated Prisoner’s Dilemma game altogether. Our work offers a new perspective on the Prisoner’s Dilemma and its predictions for cooperation in natural populations; and it provides a general framework to understand the coevolution of strategies and payoffs in iterated interactions.

I reject the Darwinian assumption that larvae and their adults evolved from a single common ancestor. Rather I posit that, in animals that metamorphose, the basic types of larvae originated as adults of different lineages, i.e., larvae were transferred when, through hybridization, their genomes were acquired by distantly related animals. "Caterpillars," the name for eruciforms with thoracic and abdominal legs, are larvae of lepidopterans, hymenopterans, and mecopterans (scorpionflies). Grubs and maggots, including the larvae of beetles, bees, and flies, evolved from caterpillars by loss of legs. Caterpillar larval organs are dismantled and reconstructed in the pupal phase. Such indirect developmental patterns (metamorphoses) did not originate solely by accumulation of random mutations followed by natural selection; rather they are fully consistent with my concept of evolution by hybridogenesis. Members of the phylum Onychophora (velvet worms) are proposed as the evolutionary source of caterpillars and their grub or maggot descendants. I present a molecular biological research proposal to test my thesis. By my hypothesis 2 recognizable sets of genes are detectable in the genomes of all insects with caterpillar grub- or maggot-like larvae: (i) onychophoran genes that code for proteins determining larval morphology/physiology and (ii) sequentially expressed insect genes that code for adult proteins. The genomes of insects and other animals that, by contrast, entirely lack larvae comprise recognizable sets of genes from single animal common ancestors.
The way we get our funding, collaborate, do our research, and get the word out has evolved over hundreds of years but we can imagine a more open science world, largely facilitated by the internet. The movement towards this more open way of doing and presenting science is coming, and it is not taking hundreds of years. If you are interested in these trends, and would like to find out more about where this is all headed and what it means to you, consider downloding Opening Science, edited by Sönke Bartling and Sascha Friesike, subtitled The Evolving Guide on How the Internet is Changing Research, Collaboration, and Scholarly Publishing. In 26 chapters by various authors from a range of disciplines the book explores the developing world of open science, starting from the first scientific revolution and bringing us to the next scientific revolution, sometimes referred to as “Science 2.0”. Some of the articles deal with the impact of the changing landscape of how science is done, looking at the impact of open science on Academia, or journal publishing, or medical research. Many of the articles look at the uses, pitfalls, and impact of specific tools, like microblogging (think Twitter), social networking, and reference management. There is lots of discussion and definition of terms you might use or misuse like “altmetrics” and “impact factor”. Science will probably never be completely open, and Twitter will probably never replace the journal article,

Overall health status after a disaster may be associated with long-term physical morbidity and mortality. Little is known about factors associated with overall health status in the aftermath of disasters. We examined self-rated health in relation to disaster characteristics, social resources, and post-disaster outcomes in a sample of adults who experienced the 2004 Florida hurricanes. We interviewed a representative sample of 1,452 adults aged 18 years and older residing in the 33 Florida counties that were in the direct path of at least one of the 2004 hurricanes (Charley, Frances, Ivan, Jeanne). Overall health status was assessed using a self-rating format known to be predictive of mortality. Poor self-rated health was endorsed by 14.6% of the sample. Final multivariable models showed that poor self-rated health was associated with older age (p < 0.001), extreme fear during the hurricane (p = 0.03), low social support (p = 0.03), and depression (p = 0.003) since the hurricane. Self-rated health following the Florida hurricanes was strongly associated with two variables (social support and depression) that potentially can be mitigated through targeted interventions after disasters. Future work should evaluate secondary prevention strategies that can address general health-related concerns in the wake of a disaster.

: Background: In its 1999 report To Err Is Human: Building a Safer Health System, the Institute of Medicine (IOM) suggested that between 44,000 and 98,000 Americans die annually as a result of medical errors. The report urged health care institutions to break the silence surrounding such errors and to implement changes that would promote a culture of safety.

Recovery was first officially promoted in New Zealand in 1998 and it became a key concept in mental health service development. Since the mid 2000s however, recovery has been on the wane in New Zealand, but the fundamental concepts within the term live on in two more recently adopted terms: whanau ora and well-being. He Korowai Oranga (Maori Health Strategy) defines whanau ora as families being supported to achieve health and well-being. The extended family is recognized as a source of strength, identity, security and support. Whanau ora is underpinned by Te Whare Tapa Wha, a well-being model that focuses on health being a balance between Taha Wairua (spiritual health), Taha Tinana (physical health), Taha Hinengaro (psychological health) and Taha Whānau (family health). New Zealanders are also using the term well-being, not just for the whole population but for people diagnosed with mental illness. The advantages of placing recovery into the larger well-being agenda are reduced discrimination and segregation of people with a diagnosis into a distinct population group, reduced association with medical and deficits approaches that can counter the recovery approach, and bypassing the dilution of the recovery approach that has occurred in traditional services.

Latin America is one of the most ethnoracially heterogeneous regions of the world. Despite this, health disparities research in Latin America tends to focus on gender, class and regional health differences while downplaying ethnoracial differences. Few scholars have conducted studies of ethnoracial identification and health disparities in Latin America. Research that examines multiple measures of ethnoracial identification is rarer still. Official data on race/ethnicity in Latin America are based on self-identification which can differ from interviewer-ascribed or phenotypic classification based on skin color. We use data from Brazil, Colombia, Mexico, and Peru to examine associations of interviewer-ascribed skin color, interviewer-ascribed race/ethnicity, and self-reported race/ethnicity with self-rated health among Latin American adults (ages 18-65). We also examine associations of observer-ascribed skin color with three additional correlates of health - skin color discrimination, class discrimination, and socio-economic status. We find a significant gradient in self-rated health by skin color. Those with darker skin colors report poorer health. Darker skin color influences self-rated health primarily by increasing exposure to class discrimination and low socio-economic status.

In this paper we study an evolving email network model first introduced by Wang and De Wilde, to the best of our knowledge. The model is analyzed by formulating the network topology as a random process and studying the dynamics of the process. Our analytical results show a number of steady state properties about the email traffic between different nodes and the aggregate networking behavior (i.e., degree distribution, clustering coefficient, average path length, and phase transition), and also confirm the empirical results obtained by Wang and De Wilde. We also conducted simulations confirming the analytical results. Extensive simulations were run to evaluate email traffic behavior at the link and network levels, phase transition phenomena, and also studying the behavior of email traffic in a hierarchical network. The methods established here are also applicable to many other practical networks including sensor networks and social networks.

In recent decades, sporotrichosis, caused by thermally dimorphic fungi Sporothrix schenckii complex, has become an emerging infection in many parts of the world. Pulmonary infection with S. schenckii still remains relatively uncommon, possibly due to underrecognition. Pulmonary sporotrichosis presents with distinct clinical and radiological patterns in both immunocompetent and immunocompromised hosts and can often result in significant morbidity and mortality despite treatment. Current understanding regarding S. schenckii biology, epidemiology, immunopathology, clinical diagnostics, and treatment options has been evolving in the recent years with increased availability of molecular sequencing techniques. However, this changing knowledge has not yet been fully translated into a better understanding of the clinical aspects of pulmonary sporotrichosis, as such current management guidelines remain unsupported by high-level clinical evidence. This article examines recent advances in the knowledge of sporotrichosis and its application to the difficult challenges of managing pulmonary sporotrichosis.

The central stars of highly evolved planetary nebulae (PNe) are expected to have closely similar absolute visual magnitudes MV. This enables us to determine approximate distances to these sources where one knows their central star visual magnitudes, and levels of extinction. We find that such an analysis implies values of D which are similar to those determined by Phillips; Cahn, Kaler & Stanghellin; Acker, and Daub. However, our distances are very much smaller than those of Zhang; Bensby & Lundstrom, and van de Steene & Zijlstra. The reasons for these differences are discussed, and can be traced to errors in the assumed relation between brightness temperature and radius. Finally, we determine that the binary companions of such stars can be no brighter than MV~ 6mag, implying a spectral type of K0 or later in the case of main-sequence stars.

The interaction between the evolution of the game and the underlying network structure with evolving snowdrift game model is investigated. The constructed network follows a power-law degree distribution typically showing scale-free feature. The topological features of average path length, clustering coefficient, degree-degree correlations and the dynamical feature of synchronizability are studied. The synchronizability of the constructed networks changes by the interaction. It will converge to a certain value when sufficient new nodes are added. It is found that initial payoffs of nodes greatly affect the synchronizability. When initial payoffs for players are equal, low common initial payoffs may lead to more heterogeneity of the network and good synchronizability. When initial payoffs follow certain distributions, better synchronizability is obtained compared to equal initial payoff. The result is also true for phase synchronization of nonidentical oscillators.

This paper discuss the problem of increased programming time for intrinsic evolvable hardware (EHW) as the complexity of the circuit grows. We develop equations for the size of the population, n, and the number of generations required for the population to converge, ngen, based on L, the length of the programming string. We show that the processing time of the computer becomes negligible for intrinsic EHW since the selection/crossover/mutation steps are only done once per generation, suggesting there is room for use of more complex evolutionary algorithms m intrinsic EHW. F i y , we review the state of the practice and discuss the notion of a system design approach for intrinsic EHW.

Neuromorphic computing - brain-like computing in hardware - typically requires myriad complimentary metal oxide semiconductor spiking neurons interconnected by a dense mesh of nanoscale plastic synapses. Memristors are frequently cited as strong synapse candidates due to their statefulness and potential for low-power implementations. To date, plentiful research has focused on the bipolar memristor synapse, which is capable of incremental weight alterations and can provide adaptive self-organisation under a Hebbian learning scheme. In this paper, we consider the unipolar memristor synapse - a device capable of non-Hebbian switching between only two states (conductive and resistive) through application of a suitable input voltage - and discuss its suitability for neuromorphic systems. A self-adaptive evolutionary process is used to autonomously find highly fit network configurations. Experimentation on two robotics tasks shows that unipolar memristor networks evolve task-solving controllers faster than both bipolar memristor networks and networks containing constant non-plastic connections whilst performing at least comparably.

Life-cycle planning is an evolving concept in the management of oil and gas projects. BHP Petroleum now interprets this idea to include all development planning from discovery and field appraisal to final abandonment and includes safety, environmental, technical, plant, regulatory, and staffing issues. This article describes in the context of the Timor Sea, how despite initial successes and continuing facilities upgrades, BHPP came to perceive that current operations could be the victim of early development successes, particularly in the areas of corrosion and maintenance. The search for analogies elsewhere lead to the UK North Sea, including the experiences of Britoil and BP, both of which performed detailed Life of Field studies in the later eighties. These materials have been used to construct a format and content for total Life-cycle plans in general and the social changes required to ensure their successful application in Timor Sea operations and deployment throughout Australia.
A single-column model of the evolving stable boundary layer (SBL) is tested for self-similar properties of the flow and effects of ambient forcing. The turbulence closure of the model is diagnostic, based on the K-theory approach, with a semi-empirical form of the mixing length, and empirical stability functions of the Richardson number. The model results, expressed in terms of local similarity scales, are universal functions, satisfied in the entire SBL. Based on similarity expression, a realizability condition is derived for the minimum allowable turbulent heat flux in the SBL. Numerical experiments show that the development of "horse-shoe" shaped, fixed-elevation hodographs in the interior of the SBL around sunrise is controlled by effects imposed by surface thermal forcing.
Social living ultimately depends on coordination between group members, and communication is necessary to make this possible. We suggest that this might have been the key selection pressure acting on the evolution of language in humans and use a behavioural coordination model to explore the impact of communication efficiency on social group coordination. We show that when language production is expensive but there is an individual benefit to the efficiency with which individuals coordinate their behaviour, the evolution of efficient communication is selected for. Contrary to some views of language evolution, the speed of evolution is necessarily slow because there is no advantage in some individuals evolving communication abilities that much exceed those of the community at large. However, once a threshold competence has been achieved, evolution of higher order language skills may indeed be precipitate. PMID:28083091

Organisms have a remarkable capacity to respond to environmental change. They can either respond directly, by means of phenotypic plasticity, or they can slowly adapt through evolution. Yet, how phenotypic plasticity links to evolutionary adaptability is largely unknown. Current studies of plasticity tend to adopt a phenomenological reaction norm (RN) approach, which neglects the mechanisms underlying plasticity. Focusing on a concrete question - the optimal timing of bacterial sporulation - we here also consider a mechanistic approach, the evolution of a gene regulatory network (GRN) underlying plasticity. Using individual-based simulations, we compare the RN and GRN approach and find a number of striking differences. Most importantly, the GRN model results in a much higher diversity of responsive strategies than the RN model. We show that each of the evolved strategies is pre-adapted to a unique set of unseen environmental conditions. The regulatory mechanisms that control plasticity therefore critically link phenotypic plasticity to the adaptive potential of biological populations.

A systematic inspection of the far-infrared (FIR) properties of evolved stars allows not only to constrain physical models, but also to understand the chemical evolution that takes place in the end of their lives. In this work we intend to study the circumstellar envelopes (CSE) on a sample of stars in the THROES catalogue from AGB/post-AGB stars to planetary nebulae using photometry and spectroscopy provided by the PACS instrument on-board Herschel telescope. In the first part we are interested in obtaining an estimate of the size of FIR emitting region and to sort our targets in two classes: point-like and extended. Secondly, we focus on the molecular component of the envelope traced by carbon monoxide (CO) rotational lines. We conduct a line survey on a sample of evolved stars by identifying and measuring flux of both 12CO and 13CO isotopologues in the PACS range, while looking at the overall properties of the sample. Lastly, we will be interested in obtaining physical parameters of the CSE, namely gas temperature, mass and mass-loss rate on a sample of carbon stars. For that, we make use of PACS large wavelength coverage, which enables the simultaneous study of a large number of CO transitions, to perform the rotational diagram analysis. We report the detection of CO emission in a high number of stars from the catalogue, which were mostly classified as point-like targets with a few exceptions of planetary nebulae. High J rotational number transitions were detected in a number of targets, revealing the presence of a significant amount of hot gas (T ˜ 400-900 K) and high mass-loss rates. We conclude that Herschel/PACS is in a privileged position to detect a new population of warmer gas, typically missed in sub-mm/mm observations.

The growing discrepancy between the need and the availability of donor livers has resulted in evolving surgical approaches in liver transplantation during the last two decades to expand the donor pool. One approach is to transplant partial grafts, obtained either from a living donor or splitting a cadaveric donor liver. For both surgical methods, it is important to obtain a minimal viable graft volume to prevent small-for-size syndrome and graft failure. This minimal volume, expressed as graft-to-whole body ratio, must be between 0.8 and 1%. Living donor liver transplantation (LDLT) became the primary transplant option in many Asian countries and is increasingly performed as an adjunct transplant option in countries with low donation rates. Split liver transplantation (SLT) is a surgical method that creates two allografts from one deceased donor. The most widely used splitting technique is the division of the liver into a left lateral sectoral graft (segments 2 and 3) for a pediatric patient and a right trisegmental graft (segments 1 and 4 to 8) for an adult patient. Both LDLT and SLT are also important and established methods for the treatment of pediatric patients. Another evolving surgical approach is auxiliary liver transplantation, which describes the transplanting a whole or partial graft with preservation of the partial native liver. This bridging technique is applied in patients with fulminate liver failure and should allow the regeneration of the injured liver with the potential to discontinue immunosuppression. Other methods such as xenotransplantation, as well as hepatocyte and stem cell transplantation, are promising approaches that are still in experimental phases.

Driven by intergroup competition, social norms, beliefs, and practices can evolve in ways that more effectively tap into a wide variety of evolved psychological mechanisms to foster group-beneficial behavior. The more powerful such evolved mechanisms are, the more effectively culture can potentially harness and manipulate them to generate greater phenotypic variation across groups, thereby fueling cultural group selection.

The Centers for Disease Control and Prevention (CDC) transformed its approach to preparing for and responding to public health emergencies following the anthrax attacks of 2001. The Office of Public Health Preparedness and Response, an organizational home for emergency response at CDC, was established, and 4 programs were created or greatly expanded after the anthrax attacks: (1) an emergency management program, including an Emergency Operations Center; (2) increased support of state and local health department efforts to prepare for emergencies; (3) a greatly enlarged Strategic National Stockpile of medicines, vaccines, and medical equipment; and (4) a regulatory program to assure that work done on the most dangerous pathogens and toxins is done as safely and securely as possible. Following these changes, CDC led responses to 3 major public health emergencies: the 2009-10 H1N1 influenza pandemic, the 2014-16 Ebola epidemic in West Africa, and the ongoing Zika epidemic. This article reviews the programs of CDC's Office of Public Health Preparedness, the major responses, and how these responses have resulted in changes in CDC's approach to responding to public health emergencies.

A life-span health-behavior model was investigated in this longitudinal study of personality influences on health. Teachers assessed 963 elementary school children on traits that formed scales assessing the dimensions of the five-factor (Big Five) model of personality. Smoking, alcohol use, body mass index (BMI), and self-rated health were assessed 40 years later in midlife. Childhood personality traits were significantly associated with all four outcomes, and the effects were consistently larger for women than men. For men and women, childhood Conscientiousness was associated with less adult smoking and better adult self-rated health and, for women only, with lower adult BMI. Mediation analyses suggested that the effects of Conscientiousness on self-rated health were partially mediated by smoking and BMI. These findings add to the growing evidence that childhood personality traits predict adult health outcomes, and are discussed in terms of future testing of the life-span health-behavior model.

The Association of American Veterinary Medical College's (AAVMC's) role in the progression of academic veterinary medical education has been about building successful partnerships in the US and internationally. Membership in the association has evolved over the past 50 years, as have traditions of collaboration that strengthen veterinary medical education and the association. The AAVMC has become a source of information and a place for debate on educational trends, innovative pedagogy, and the value of a diverse learning environment. The AAVMC's relationship with the American Veterinary Medical Association Council on Education (AVMA COE), the accreditor of veterinary medical education recognized by the United Sates Department of Education (DOE), is highlighted here because of the key role that AAVMC members have played in the evolution of veterinary accreditation. The AAVMC has also been a partner in the expansion of veterinary medical education to include global health and One Health and in the engagement of international partners around shared educational opportunities and challenges. Recently, the association has reinforced its desire to be a truly international organization rather than an American organization with international members. To that end, strategic AAVMC initiatives aim to expand and connect the global community of veterinary educators to the benefit of students and the profession around the world. Tables in this article are intended to provide historical context, chronology, and an accessible way to view highlights.

This paper examines the association of political ideology with health lifestyle practices and self-rated health in Belarus, Russia, and Ukraine. The political trajectory of post-Soviet societies has taken two divergent paths, either toward democracy or autocracy. The health trajectory has followed the same pattern with the more autocratic states continuing to experience a mortality crisis, while those former socialist countries that have embraced democracy and moved closer to the West have escaped this crisis. This paper investigates whether political ideology in three post-Soviet countries that are firmly (Belarus), increasingly (Russia), or recently (Ukraine) autocratic is related to health lifestyles and health self-ratings. Data were collected by face-to-face interviews (N = 8406) with a representative national sample of the adult population. The results show that respondents who are against restoring communism have healthier lifestyles and rate their health better than respondents who wish to see communism return.

Most studies of disease spreading consider the underlying social network as obtained without the contagion, though epidemic influences people's willingness to contact others: A "friendly" contact may be turned to "unfriendly" to avoid infection. We study the susceptible-infected disease-spreading model on signed networks, in which each edge is associated with a positive or negative sign representing the friendly or unfriendly relation between its end nodes. In a signed network, according to Heider's theory, edge signs evolve such that finally a state of structural balance is achieved, corresponding to no frustration in physics terms. However, the danger of infection affects the evolution of its edge signs. To describe the coupled problem of the sign evolution and disease spreading, we generalize the notion of structural balance by taking into account the state of the nodes. We introduce an energy function and carry out Monte Carlo simulations on complete networks to test the energy landscape, where we find local minima corresponding to the so-called jammed states. We study the effect of the ratio of initial friendly to unfriendly connections on the propagation of disease. The steady state can be balanced or a jammed state such that a coexistence occurs between susceptible and infected nodes in the system.
Freud based his oedipal theory on three clinical observations of adult romantic relationships: (1) Adults tend to split love and lust; (2) There tend to be sex differences in the ways that men and women split love and lust; (3) Adult romantic relationships are unconsciously structured by the dynamics of love triangles in which dramas of seduction and betrayal unfold. Freud believed that these aspects of adult romantic relationships were derivative expressions of a childhood oedipal conflict that has been repressed. Recent research conducted by evolutionary psychologists supports many of Freud's original observations and suggests that Freud's oedipal conflict may have evolved as a sexually selected adaptation for reproductive advantage. The evolution of bi-parental care based on sexually exclusive romantic bonds made humans vulnerable to the costs of sexual infidelity, a situation of danger that seriously threatens monogamous bonds. A childhood oedipal conflict enables humans to better adapt to this longstanding evolutionary problem by providing the child with an opportunity to develop working models of love triangles. On the one hand, the oedipal conflict facilitates monogamous resolutions by creating intense anxiety about the dangers of sexual infidelity and mate poaching. On the other hand, the oedipal conflict in humans may facilitate successful cheating and mate poaching by cultivating a talent for hiding our true sexual intentions from others and even from ourselves. The oedipal conflict in humans may be disguised by evolutionary design in order to facilitate tactical deception in adult romantic relationships.

MR enterography is playing an evolving role in the evaluation of small bowel Crohn's disease (CD). Standard MR enterography includes a combination of rapidly acquired T2 sequence, balanced steady-state acquisition, and contrast enhanced T1-weighted gradient echo sequence. The diagnostic performance of these sequences has been shown to be comparable, and in some respects superior, to other small bowel imaging modalities. The findings of CD on MR enterography have been well described in the literature. New and emerging techniques such as diffusion-weighted imaging (DWI), dynamic contrast enhanced MRI (DCE-MRI), cinematography, and magnetization transfer, may lead to improved accuracy in characterizing the disease. These advanced techniques can provide quantitative parameters that may prove to be useful in assessing disease activity, severity, and response to treatment. In the future, MR enterography may play an increasing role in management decisions for patients with small bowel CD; however, larger studies are needed to validate these emerging MRI parameters as imaging biomarkers.

By mimicking Nature, we can design and synthesize inorganic smart materials that are reactive to biological tissues. These smart materials can be utilized to design innovative third-generation biomaterials, which are able to not only optimize their interaction with biological tissues and environment, but also mimic biogenic materials in their functionalities. The biomedical applications involve increasing the biomimetic levels from chemical composition, structural organization, morphology, mechanical behavior, nanostructure, and bulk and surface chemical–physical properties until the surface becomes bioreactive and stimulates cellular materials. The chemical–physical characteristics of biogenic hydroxyapatites from bone and tooth have been described, in order to point out the elective sides, which are important to reproduce the design of a new biomimetic synthetic hydroxyapatite. This review outlines the evolving applications of biomimetic synthetic calcium phosphates, details the main characteristics of bone and tooth, where the calcium phosphates are present, and discusses the chemical–physical characteristics of biomimetic calcium phosphates, methods of synthesizing them, and some of their biomedical applications.

Observations of galaxies using large surveys (SDSS, COSMOS, PRIMUS, etc.) have firmly established a global view of galaxy properties out to z~1. Galaxies are broadly divided into two classes: blue, typically disk-like star forming galaxies and red, typically elliptical quiescent ones with little star formation. The star formation rates (SFR) and stellar masses of star forming galaxies form an empirical relationship referred to as the "star formation main sequence". Over cosmic time, this sequence undergoes significant decline in SFR and causes the overall cosmic star formation decline. Simultaneously, physical processes cause significant fractions of star forming galaxies to "quench" their star formation. Hierarchical structure formation and cosmological models provide precise predictions of the evolution of the underying dark matter, which serve as the foundation for these detailed trends and their evolution. Whatever trends we observe in galaxy properties can be interpreted within the narrative of the underlying dark matter and halo occupation framework. More importantly, through careful statistical treatment and precise measurements, this connection can be utilized to better constrain and understand key elements of galaxy evolution. In this spirit, for my dissertation I connect observations of evolving galaxy properties to the framework of the hierarchical Universe and use it to better understand physical processes responsible for the cessation of star formation in galaxies. For instance, through this approach, I constrain the quenching timescale of central galaxies and find that they are significantly longer than the quenching timescale of satellite galaxies.

In the era of big data, information regarding the same objects can be collected from increasingly more sources. Unfortunately, there usually exist conflicts among the information coming from different sources. To tackle this challenge, truth discovery, i.e., to integrate multi-source noisy information by estimating the reliability of each source, has emerged as a hot topic. In many real world applications, however, the information may come sequentially, and as a consequence, the truth of objects as well as the reliability of sources may be dynamically evolving. Existing truth discovery methods, unfortunately, cannot handle such scenarios. To address this problem, we investigate the temporal relations among both object truths and source reliability, and propose an incremental truth discovery framework that can dynamically update object truths and source weights upon the arrival of new data. Theoretical analysis is provided to show that the proposed method is guaranteed to converge at a fast rate. The experiments on three real world applications and a set of synthetic data demonstrate the advantages of the proposed method over state-of-the-art truth discovery methods.

The view of species as entities subjected to natural selection and amenable to change put forth by Charles Darwin and Alfred Wallace laid the conceptual foundation for understanding speciation. Initially marred by a rudimental understanding of hereditary principles, evolutionists gained appreciation of the mechanistic underpinnings of speciation following the merger of Mendelian genetic principles with Darwinian evolution. Only recently have we entered an era where deciphering the molecular basis of speciation is within reach. Much focus has been devoted to the genetic basis of intrinsic postzygotic isolation in model organisms and several hybrid incompatibility genes have been successfully identified. However, concomitant with the recent technological advancements in genome analysis and a newfound interest in the role of ecology in the differentiation process, speciation genetic research is becoming increasingly open to non-model organisms. This development will expand speciation research beyond the traditional boundaries and unveil the genetic basis of speciation from manifold perspectives and at various stages of the splitting process. This review aims at providing an extensive overview of speciation genetics. Starting from key historical developments and core concepts of speciation genetics, we focus much of our attention on evolving approaches and introduce promising methodological approaches for future research venues.

The insular dwarfism seen in Pleistocene elephants has come to epitomize the island rule; yet our understanding of this phenomenon is hampered by poor taxonomy. For Mediterranean dwarf elephants, where the most extreme cases of insular dwarfism are observed, a key systematic question remains unresolved: are all taxa phyletic dwarfs of a single mainland species Palaeoloxodon antiquus (straight-tusked elephant), or are some referable to Mammuthus (mammoths)? Ancient DNA and geochronological evidence have been used to support a Mammuthus origin for the Cretan 'Palaeoloxodon' creticus, but these studies have been shown to be flawed. On the basis of existing collections and recent field discoveries, we present new, morphological evidence for the taxonomic status of 'P'. creticus, and show that it is indeed a mammoth, most probably derived from Early Pleistocene Mammuthus meridionalis or possibly Late Pliocene Mammuthus rumanus. We also show that Mammuthus creticus is smaller than other known insular dwarf mammoths, and is similar in size to the smallest dwarf Palaeoloxodon species from Sicily and Malta, making it the smallest mammoth species known to have existed. These findings indicate that extreme insular dwarfism has evolved to a similar degree independently in two elephant lineages.

Populations of mobile and communicating agents describe a vast array of technological and natural systems, ranging from sensor networks to animal groups. Here, we investigate how a group-level agreement may emerge in the continuously evolving networks defined by the local interactions of the moving individuals. We adopt a general scheme of motion in two dimensions and we let the individuals interact through the minimal naming game, a prototypical scheme to investigate social consensus. We distinguish different regimes of convergence determined by the emission range of the agents and by their mobility, and we identify the corresponding scaling behaviors of the consensus time. In the same way, we rationalize also the behavior of the maximum memory used during the convergence process, which determines the minimum cognitive/storage capacity needed by the individuals. Overall, we believe that the simple and general model presented in this talk can represent a helpful reference for a better understanding of the behavior of populations of mobile agents.

The form of fluvial landscapes is known to attain stationary network configurations that settle in dynamically accessible minima of total energy dissipation by landscape-forming discharges. Recent studies have highlighted the role of the dendritic structure of river networks in controlling population dynamics of the species they host and large-scale biodiversity patterns. Here, we systematically investigate the relation between energy dissipation, the physical driver for the evolution of river networks, and the ecological dynamics of their embedded biota. To that end, we use the concept of metapopulation capacity, a measure to link landscape structures with the population dynamics they host. Technically, metapopulation capacity is the leading eigenvalue λM of an appropriate "landscape" matrix subsuming whether a given species is predicted to persist in the long run. λM can conveniently be used to rank different landscapes in terms of their capacity to support viable metapopulations. We study how λM changes in response to the evolving network configurations of spanning trees. Such sequence of configurations is theoretically known to relate network selection to general landscape evolution equations through imperfect searches for dynamically accessible states frustrated by the vagaries of Nature. Results show that the process shaping the metric and the topological properties of river networks, prescribed by physical constraints, leads to a progressive increase in the corresponding metapopulation capacity and therefore on the landscape capacity to support metapopulations—with implications on biodiversity in fluvial ecosystems.

There are a number of toroidal equilibrium (such as JSOLVER, ESC, EFIT, and VMEC) and transport codes (such as TRANSP, BALDUR, and TSC) in our community that utilize differing equilibrium representations. There are also many heating and current drive (LSC and TORRAY), and stability (PEST1-3, GATO, NOVA, MARS, DCON, M3D) codes that require this equilibrium information. In an effort to provide seamless compatibility between the codes that produce and need these equilibria, we have developed two Fortran 90 modules, MEQ and XPLASMA, that serve as common interfaces between these two classes of codes. XPLASMA provides a common equilibrium representation for the heating and current drive applications while MEQ provides common equilibrium and associated metric information needed by MHD stability codes. We illustrate the utility of this approach by presenting results of PEST-3 tearing stability calculations of an NSTX discharge performed on profiles provided by the TRANSP code. Using the MEQ module, the TRANSP equilibrium data are stored in a Fortran 90 derived type and passed to PEST3 as a subroutine argument. All calculations are performed on the fly, as the profiles evolve.

Mutants of Lactobacillus kefir short-chain alcohol dehydrogenase, used here as ketoreductases (KREDs), enantioselectively reduce the pharmaceutically relevant substrates 3-thiacyclopentanone and 3-oxacyclopentanone. These substrates differ by only the heteroatom (S or O) in the ring, but the KRED mutants reduce them with different enantioselectivities. Kinetic studies show that these enzymes are more efficient with 3-thiacyclopentanone than with 3-oxacyclopentanone. X-ray crystal structures of apo- and NADP(+)-bound selected mutants show that the substrate-binding loop conformational preferences are modified by these mutations. Quantum mechanical calculations and molecular dynamics (MD) simulations are used to investigate the mechanism of reduction by the enzyme. We have developed an MD-based method for studying the diastereomeric transition state complexes and rationalize different enantiomeric ratios. This method, which probes the stability of the catalytic arrangement within the theozyme, shows a correlation between the relative fractions of catalytically competent poses for the enantiomeric reductions and the experimental enantiomeric ratio. Some mutations, such as A94F and Y190F, induce conformational changes in the active site that enlarge the small binding pocket, facilitating accommodation of the larger S atom in this region and enhancing S-selectivity with 3-thiacyclopentanone. In contrast, in the E145S mutant and the final variant evolved for large-scale production of the intermediate for the antibiotic sulopenem, R-selectivity is promoted by shrinking the small binding pocket, thereby destabilizing the pro-S orientation.

The 7th edition of the TNM defines multifocal breast cancer as multiple simultaneous ipsilateral and synchronous breast cancer lesions, provided they are macroscopically distinct and measurable using current traditional pathological and clinical tools. According to the College of American Pathologists (CAP), the characterization of only the largest lesion is considered sufficient, unless the grade and/or histology are different between the lesions. Here, we review three potentially clinically relevant aspects of multifocal breast cancers: first, the importance of a different intrinsic breast cancer subtype of the various lesions; second, the emerging awareness of inter-lesion heterogeneity; and last but not least, the potential introduction of bias in clinical trials due to the unrecognized biological diversity of these cancers. Although the current strategy to assess the lesion with the largest diameter has clearly its advantages in terms of costs and feasibility, this recommendation may not be sustainable in time and might need to be adapted to be compliant with new evolving paradigms in breast cancer.

Understanding the structure and evolution of online bipartite networks is a significant task since they play a crucial role in various e-commerce services nowadays. Recently, various attempts have been tried to propose different models, resulting in either power-law or exponential degree distributions. However, many empirical results show that the user degree distribution actually follows a shifted power-law distribution, the so-called Mandelbrot’s law, which cannot be fully described by previous models. In this paper, we propose an evolving model, considering two different user behaviors: random and preferential attachment. Extensive empirical results on two real bipartite networks, Delicious and CiteULike, show that the theoretical model can well characterize the structure of real networks for both user and object degree distributions. In addition, we introduce a structural parameter p, to demonstrate that the hybrid user behavior leads to the shifted power-law degree distribution, and the region of power-law tail will increase with the increment of p. The proposed model might shed some lights in understanding the underlying laws governing the structure of real online bipartite networks.
