Nonlinear Associations Between Working Hours and Overwork-Related Cerebrovascular and Cardiovascular Diseases (CCVD)
Long working hours are recognized as a risk factor for cerebrovascular and cardiovascular diseases (CCVD). We investigated the relationship between working hours and different CCVD severity outcomesādeath, disability, and illnessāacross industries in Taiwan from 2006 to 2016. We applied a generalized additive mixed model to estimate the association between working hours and the rate of each severity outcome, adjusted for salary, unemployment rate, time, and a random intercept. Industry-average working hours were significantly associated with each outcome level of overwork-related CCVD, especially when monthly working hours increased from 169 (relative risk [RR]ā=ā1.46, 95% confidence interval [CI] 1.002ā2.12) to 187 (RRā=ā5.73, 95% CI 3.61ā9.08). Although RR trends declined after monthly working hours exceeded 187, excess risks remained statistically significant. Each 1-hour increase in working hours had a stronger effect on the RR increase in death and disability than on illness. Variations in CCVD risks existed across industries, with the highest risk in transportation and information. Reducing working hours is essential to preventing overwork-related CCVD, especially the more severe outcomes. We recommend further research to address possible underreporting of less severe cases, and to explore actions to narrow the gaps in risk across industries
Mortality among Lifelong Nonsmokers Exposed to Secondhand Smoke at Home: Cohort Data and Sensitivity Analyses
Evidence is growing that secondhand smoke can cause death from several diseases. The association between household exposure to secondhand smoke and disease-specific mortality was examined in two New Zealand cohorts of lifelong nonsmokers (āānever smokersāā) aged 45ā77 years. Individual census records from 1981 and 1996 were anonymously and probabilistically linked with mortality records from the 3 years that followed each census. Age- and ethnicity-standardized mortality rates were compared for never smokers with and without home exposure to secondhand smoke (based on the reported smoking behavior of other household members). Relative risk estimates adjusted for age, ethnicity, marital status, and socioeconomic position showed a significantly greater mortality risk for never smokers living in households with smokers, with excess mortality attributed to tobacco-related diseases, particularly ischemic heart disease and cerebrovascular disease, but not lung cancer. Adjusted relative risk estimates for all cardiovascular diseases were 1.19 (95 % confidence interval: 1.04, 1.38) for men and 1.01 (95 % confidence interval: 0.88, 1.16) for women from the 1981ā1984 cohort, and 1.25 (95 % confidence interval: 1.06, 1.47) for men and 1.35 (95 % confidence interval: 1.11, 1.64) for women from the 1996ā1999 cohort. Passive smokers also had nonsignificantly increased mortality from respiratory disease. Sensitivity analyses in-dicate that these findings are not due to misclassification bias. cohort studies; mortality; myocardial ischemia; neoplasms; New Zealand; respiratory tract diseases; tobacc

Are Maternal Social Networks and Perceptions of Trust Associated with Suspected Autism Spectrum Disorder in Offspring? A Population-Based Study in Japan
Objective: To investigate the associations of maternal social networks and perceptions of trust with the prevalence of suspected autism spectrum disorders in 18-month-old offspring in Japan. Methods: Questionnaires included measurements of maternal social networks (number of relatives or friends they could call upon for assistance), maternal perceptions of trust, mutual assistance (i.e. individual measures of ācognitive social capitalā), and social participation (i.e. individual measures of āstructural social capitalā) as well as the Modified Checklist for Autism in Toddlers to detect suspected autism spectrum disorder (ASD). These tools were mailed to all families with 18-month-old toddlers in Chiba, a city near Tokyo (N = 6061; response rate: 64%). The association between social capital or social network indicators and suspected ASD were analyzed, adjusted for covariates by logistic regression analysis. Results: Low maternal social trust was found to be significantly positively associated with suspected ASD in toddlers compared with high maternal social trust (adjusted odds ratio [OR]: 1.82, 95% confidence interval [CI]: 1.38 to 2.40); mutual aid was also significantly positively related (low vs. high: OR, 1.82, 95% CI: 1.38 to 2.40). However, maternal community participation showed U-shape association with suspected ASD of offspring. Maternal social network showed consistent inverse associations with suspected ASD of offspring, regardless of the type of social connection (e.g., relatives, neighbors, or friends living outside of their neighborhood). Conclusions: Mothers' cognitive social capital and social networks, but not structural social capital, might be associated with suspected ASD in offspring
Less comprehensive social policies may contribute to lower life expectancies and worse health in the U.S. compared to other high-income countries
Americans lead shorter and less healthy lives than people in other high-income countries. Is this US health disadvantage specific to some US populations, diseases, or particular age groups? And what explains these variations in the length and quality of life between Americans and other high-income countries? Mauricio Avendano and Ichiro Kawachi review the evidence and find the American health disadvantage begins at birth and extends across the life-course, and it is particularly marked for American women and for regions in the US South and Midwest. They propose explanations that include differences in health care, individual behaviors, socioeconomic inequalities, and the physical and the built environment. However, crucial differences in social policy between the US and other high income countries may also underlie an important part of the USā health disadvantage

Do residents of food deserts express different food buying preferences compared to residents of food oases? A mixed-methods analysis
Background: Many people lack access to food stores that provide healthful food. Neighborhoods with poor supermarket access have been characterized as āfood desertsā (as contrast with āfood oasesā). This study explored factors influencing food buying practices among residents of food deserts versus food oases in the city of Boston, USA. Methods: We used the mixed-methods approach of concept mapping, which allows participants to identify, list, and organize their perceptions according to importance. Resulting maps visually illustrate priority areas. Results: Sixty-seven low-income adults completed the concept mapping process that identified 163 unique statements (e.g. relating to affordability, taste, and convenience) that influence food buying practices. Multivariate statistical techniques grouped the 163 statements into 8 clusters or concepts. Results showed that average cluster ratings and rankings were similar between residents of food deserts and food oases. Conclusions: The implication of this study pertains to the importance of community resources and emergency food assistance programs that have served to minimize the burden associated with hunger and poor food access among low-income, urban populations
Discrimination and Telomere Length Among Older Adults in the United States
Abstract Objectives:
Chronic stress from experiencing discrimination can lead to long-term changes in psychological and physiologic responses, including shorter leukocyte telomere length. We examined the association between leukocyte telomere length and variations in the association by race or type of discrimination. Methods:
Our study consisted of 3868 US-born non-Hispanic black (hereinafter, black) and non-Hispanic white (hereinafter, white) adult participants from the 2008 Health and Retirement Study biomarker sample with complete sociodemographic and discrimination information. We examined major lifetime unfair treatment and everyday discrimination. Coarsened exact matching matched exposed and unexposed participants on several sociodemographic factors. Coarsened exact matching creates analytic weights for the matched data sets. We applied weighted linear regression to the matched data sets. We conducted 2 subanalyses in which we matched on potential mediatorsāphysical activity, smoking status, and obesityāand examined if racism was associated with shorter telomere length compared with other attributes. All analyses were stratified by race. Results:
We found no difference in telomere length for black and white participants reporting major lifetime unfair treatment (Ī² = 0.09; 95% CI, ā0.33 to 0.15) or everyday discrimination (Ī² = 0.04; 95% CI, ā0.12 to 0.40). Everyday discrimination was associated with shorter leukocyte telomere length among black people (Ī² = ā0.23; 95% CI, ā0.44 to ā0.01) but not among white people (Ī² = 0.05; 95% CI, ā0.01 to 0.10). Matching on potential mediators generally decreased the effect estimate among black people. Conclusions:
Experiencing everyday discrimination was associated with shortened telomere length among older black adults. Further research is needed to understand the adverse physiologic effects of discrimination to create effective interventions

Social Capital and Health: A Review of Prospective Multilevel Studies
Background: This article presents an overview of the concept of social capital, reviews prospective multilevel analytic studies of the association between social capital and health, and discusses intervention strategies that enhance social capital. Methods: We conducted a systematic search of published peer-reviewed literature on the PubMed database and categorized studies according to health outcome. Results: We identified 13 articles that satisfied the inclusion criteria for the review. In general, both individual social capital and area/workplace social capital had positive effects on health outcomes, regardless of study design, setting, follow-up period, or type of health outcome. Prospective studies that used a multilevel approach were mainly conducted in Western countries. Although we identified some cross-sectional multilevel studies that were conducted in Asian countries, including Japan, no prospective studies have been conducted in Asia. Conclusions: Prospective evidence from multilevel analytic studies of the effect of social capital on health is very limited at present. If epidemiologic findings on the association between social capital and health are to be put to practical use, we must gather additional evidence and explore the feasibility of interventions that build social capital as a means of promoting health

Social participation and mental health: moderating effects of gender, social role and rurality
Background: Previous studies have reported that older peopleās social participation has positive effects on their health. However, some studies showed that the impacts of social participation on health differ by gender. We sought to examine whether the effects of social participation on mental health differ for men and women in a Japanese population. We also examined the moderating influence of social position within the organization as well as urban/rural locality. Methods: We used two waves of the Aichi Gerontological Evaluation Studyās longitudinal survey, which targeted residents with aged 65 years or over (n = 2,728) in a central part of Japan. The first wave survey was conducted in 2003, and the second wave in 2006. Depressive symptoms of the study participants were assessed using the short version of the Geriatric Depression Scale (GDS-15). A multilevel logistic regression model was used with individual-level as level 1 and the school district-level as level 2. Results: We found that higher social participation and performing key roles in the organization had protective effects on depressive symptoms for women. However, there were no main effects of these variables for the mental health of men. We found an interaction between social participation, organizational position, and rural residence among men only. That is, men who occupied leadership positions in organizations reported better mental health, but only in rural areas. Conclusions: Our findings support the notion that increasing the opportunities for social participation improves older peopleās heath, especially for women. However, in the rural Japanese context, offering men meaningful roles within organizations may be important
Prenatal Alcohol Exposure and Child Psychosocial Behavior: A Sibling Fixed-Effects Analysis
Background: The association between low levels of alcohol consumption during pregnancy and children's health remains unclear because of the difficulty in ruling out residual genetic and environmental confounding factors. In this study, using a within-family sibling fixed effects design, we sought to examine the association between low prenatal alcohol exposures (PAE) and children's overall psychosocial behavior in a Japanese cohort.Methods: We used maternal and sibling data from the Japanese Study of Stratification, Health, Income and Neighborhood 2012-2013. Households were recruited from the Tokyo metropolitan area through clustered random sampling. Children under 18 years old who have siblings (n = 1,600) and their mothers were selected. PAE status was retrospectively measured, and classified by binominal and continuous measurements. Outcome measures of children's psychosocial behavior were assessed with the Child Behavior Checklist T-score.Results: Low PAE was significantly associated with the offspring's anxiety problems (Ī² = 1.54, 95%CI = 0.26, 2.82) and internalizing problems (Ī² = 2.73, 95%CI = 0.87, 4.60), and marginally significant with the offspring's total problem scores (Ī² = 2.34, 95%CI = ā0.24, 4.92). There was no significant difference in PAE between boys and girls when it comes to behavioral problems.Conclusions: Low PAE was associated with children's anxiety, internalizing problems and overall problems, taking into account possible unobserved genetic and environmental confounding influences
