Characteristics of employment history and self-perceived barriers to healthcare access.

BACKGROUND: Research suggests that people in disadvantaged social positions are more likely to perceive barriers to accessing healthcare, especially to specialists and preventive services. In this study, we analyze if adversity during past employment histories (e.g. spells of unemployment) is linked to subsequent subjectively perceived barriers in healthcare access. Further, we investigate if the associations vary according to national healthcare access and quality indicators. METHODS: We use data from the Survey of Health, Ageing and Retirement in Europe with a study sample of 31 616 men and women aged 52-80 from 25 countries. Data include retrospective information on employment histories allowing us to derive characteristics of past careers, including the number of unemployment periods, main occupational position and pension contributions. Barriers to healthcare access are measured by self-perceived forgone care due to costs and unavailability of services. We apply multilevel Poisson regression for binary outcomes and test for cross-level interactions between career characteristics and national healthcare system characteristics. RESULTS: Career characteristics are linked to later self-perceived healthcare access barriers, consistently in the case of cost barriers and less consistently for unavailability of services. Associations are similar for men and women, and persist after controlling for current income, wealth and subjective health. We find no cross-level interactions between career characteristics and country-level healthcare access and quality indicators. CONCLUSION: Self-perceived barriers to healthcare access are linked to people's past working lives. More in-depth investigation is needed to identify the reasons for the lingering effects of characteristics of employment history on reduced healthcare access.

Associations of state-level and county-level hate crimes with individual-level cardiovascular risk factors in a prospective cohort study of middle-aged Americans: the National Longitudinal Survey of Youths 1979.

BACKGROUND: There have been long-standing debates about the potential health consequences of hate crimes over and above other types of crimes. Besides the direct consequences for victims, less is known about whether hate crimes have spillover effects onto the health of local residents. METHODS: We drew data on cardiovascular disease risk factors from middle-aged Americans in the National Longitudinal Survey of Youths 1979 and on hate crimes from the FBI's Uniform Crime Reports. Employing multivariable logistic regression, we estimated the associations between changes in state/county-level all and group-specific hate crime rates from 2000 to 2006 and incident individual-level diabetes, hypertension, obesity and depressive symptoms from 2008 to 2016. All models controlled for individual-level sociodemographic factors and financial strain, county-level and state-level changes in the total crime rate, the percentage of non-Hispanic Black and Hispanic/Latino residents, and median household income, as well as state-level changes in the percentage of residents aged 65 years or older and the unemployment rate. RESULTS: 1-SD increases in state-level all and race/ethnicity-based hate crime rates were associated with 20% (OR 1.20, 95% CI 1.05 to 1.35) and 15% higher odds (OR 1.15, 95% CI 1.01 to 1.31) of incident diabetes, respectively. At the county level, a 1-SD increase in the all hate crime rate was linked to 8% higher odds (OR 1.08, 95% CI 1.00 to 1.16) of obesity, while a 1-SD increase in the race/ethnicity-based hate crime rate was associated with 8% higher odds (OR 1.08, 95% CI 1.01 to 1.15) of obesity and 9% higher odds (OR 1.09, 95% CI 1.02 to 1.17) of hypertension. We found no significant associations for depressive symptoms, and no interactions between race/ethnicity-based hate crime rates and individual-level race/ethnicity. CONCLUSION: Living in areas with higher hate crime rates may confer higher odds of hypertension, diabetes and obesity.

Comparison of three indices of relative income deprivation in predicting health status.

Relative income deprivation (RID) is a known risk factor for poor health. Previous research has proposed several measures to assess RID, e.g., Income Rank and the Yitzhaki Index. Hounkpatin et al. (2020) presented a new approach - the CR˜i index - to account for the observation that individuals are more sensitive to the differences in incomes of others who are closer to them, rather than to comparisons with incomes of others far above them. Using a Japanese nationwide cohort of older adults (n = 62,438; mean [SD] age: 73.0 [5.6] years), this study compared the performance of alternative indices of RID in predicting health outcomes (depressive symptoms, functional capacity, and self-rated health), as well as the use of alternative CR˜i index weights (α weight range: -0.9 to 0.9). When 0<α<1, higher income differences lead to a more significant increase in relative deprivation, while when -1< α <0, excessively high incomes contribute less to the relative deprivation of lower income individuals in the same reference group. Results showed that all measures of relative income deprivation were associated with deteriorating mental and physical health among older Japanese adults. However, while the CR˜i index consistently outperformed the Yitzhaki Index, this did not hold true invariably when compared to the Income Rank - depending on the health outcome and the reference group. Also, while negative α parameters showed a good statistical fit in most models, the findings were not conclusive - the best-fitting CR˜i weight parameters ranged from -0.9 to 0.9. Therefore, a clear direction for the contribution of higher incomes to relative deprivation could not be established based on the study population.

Dispositional Optimism and Disaster Resilience: A natural experiment from the 2011 Great East Japan Earthquake and Tsunami.

OBJECTIVE: Dispositional optimism - the general belief that good things will happen - is considered a key asset for the preservation of mental health after a traumatic life event. However, it has been hypothesized that in extreme situations such as major disasters where positive expectations cannot overcome the grim reality on the ground, being optimistic might be a disadvantage. To test this mismatch hypothesis, this study explores whether higher pre-disaster dispositional optimism is associated with higher posttraumatic stress (PTS) and depressive symptoms among individuals who experienced the 2011 Great East Japan Earthquake and Tsunami. METHODS: Information on optimism was collected from community-dwelling residents aged ≥65 years seven months before the 2011 Earthquake/Tsunami in Iwanuma, a Japanese city located 80-km from the epicenter. Data on disaster-related personal experiences (e.g., loss of relatives or friends/housing damage), as well as depressive and PTS symptoms, were collected during a follow-up survey in 2013, 2.5 years after the earthquake and tsunami. Multiple logistic regression models were utilized to evaluate the associations between disaster experiences, optimism, and depressive/PTS symptoms among 962 participants. RESULTS: Higher pre-disaster dispositional optimism was associated with lower odds of developing depressive symptoms (OR = 0.78, 95% CI: 0.65 to 0.95) and PTS symptoms (OR = 0.83, 95% CI: 0.69 to 0.99) after the earthquake. Contrary to the mismatch hypothesis, high dispositional optimism buffered the adverse impact of housing damage on depressive symptoms (interaction term coefficient = -0.63, p = 0.0431), but not on PTS symptoms. CONCLUSIONS: In contrast to the mismatch hypothesis, the results suggest that dispositional optimism is a resilience resource among survivors of a disaster.

Evaluation of Trust Within a Community After Survivor Relocation Following the Great East Japan Earthquake and Tsunami.

Importance: Trust is a core component of social cohesion, facilitating cooperation and collective action in the face of adversity and enabling survivors to remain resilient. Residential stability is an important prerequisite of developing trusting relations among community members. However, little is known about whether the movement of internally displaced persons (IDPs) after a disaster might change community relations. Objective: We explored perceived changes in trust within 1 community directly impacted by the 2011 Great East Japan Earthquake and Tsunami. Design, Setting, and Participants: This prospective cohort study examined survey data from 3594 residents of Iwanuma City, Japan, aged 65 years or older. Data were obtained from the Iwanuma Study-part of the Japan Gerontological Evaluation Study, a nationwide cohort study established in 2010-approximately 7 months before the disaster. All Iwanuma City residents age 65 years or older (8576 residents) were eligible to participate in 2010. The response rate was 59.0% (5058 residents). A follow-up survey was conducted in 2013, approximately 2.5 years after the disaster. Of the 4380 remaining participants who answered the baseline survey, 3594 were recontacted (follow-up rate, 82.1%). Data analysis was performed from July 1, 2019, to January 9, 2020. Exposures: The number of temporarily relocated Iwanuma City survivors within 100 m and 250 m of a nonrelocated resident's home address. Main Outcomes and Measures: Perceived changes in particularized trust (ie, trusting people from the same community) and generalized trust (trusting people from other communities) measured on a 5-point Likert scale. Results: Among 3250 nonrelocated residents (1808 [55.6%] women; mean [SD] age, 76.5 [6.2] years) of Iwanuma City included in the analytic sample, multivariable-adjusted multinomial logistic regression analyses found that each standard deviation increase in the influx of internally displaced persons (1 SD = 11 IDPs) within 250 m of a resident's home address was associated with higher odds of a decrease in the resident's particularized and generalized trust (odds ratio, 1.17; 95% CI, 1.04-1.32). Conclusions and Relevance: The influx of IDPs in the host community appeared to be associated with an erosion of trust among locals. To avoid the erosion of social cohesion after a disaster, it may be crucial to provide opportunities for social interaction between old and new residents of communities.

Prospective associations between US state-level corruption and individual-level cardiovascular risk factors among middle-aged Americans: The National Longitudinal Survey of Youths 1979.

OBJECTIVES: To estimate the associations between US state-level corruption and risk factors for cardiovascular disease, one of the leading causes of mortality and morbidity in the nation. METHODS: We used a US nationally-representative sample of middle-aged adults from the National Longitudinal Survey of Youths 1979 and data from the Corruption in America Survey to estimate the associations between state-level illegal (private gains) corruption and legal (political gains) corruption in 2013 and individual-level risks of incident diabetes, hypertension, obesity, and depression between 2014 and 2016. RESULTS: Medium and higher levels of illegal corruption were associated with odds ratios (ORs) of 1.75 (95% CI 1.06-2.88) for incident diabetes and 1.70 (95% CI 1.15-2.51) for incident hypertension, respectively. Furthermore, a higher level of legal corruption was associated with ORs of 1.84 (95% CI 1.08-3.13) for diabetes and 1.58 (95% CI 1.05-2.38) for hypertension. No consistent associations were observed for obesity or depression. CONCLUSIONS: Our findings suggest that higher levels of corruption contribute to increased risks of developing diabetes and hypertension. Investing resources into fighting corruption may be means to reduce the national burden of cardiovascular disease.

Associations Between Community Social Capital and Preservation of Functional Capacity in the Aftermath of a Major Disaster.

The strength of social connections in the community ("social capital") is hypothesized to be a crucial ingredient in disaster resilience. We examined whether community-level social capital is correlated with the ability to maintain functional capacity among older residents who experienced the 2011 Great East Japan Earthquake and Tsunami. The baseline of our cohort (mean age, 74 years) was established in 2010, 7 months before the disaster in Iwanuma, a Japanese city located 80 km from the epicenter. Disaster-related personal experiences (e.g., housing damage or relocation) were assessed through a follow-up survey (n = 3,594; follow-up rate, 82.1%) conducted in 2013, 2.5 years after the earthquake. Multiple membership multilevel models were used to evaluate the associations between functional capacity, measured by the Instrumental Activities of Daily Living scale, and 3 subscales of community-level social capital: social cohesion, social participation, and reciprocity. Community-level social participation was associated with a lower risk of functional decline after disaster exposure. The average level of social participation in the community also mitigated the adverse impact of housing damage on functional status, suggesting a buffering mechanism.

An Age-Period-Cohort Analysis of Stroke Mortality Attributable to Low Physical Activity in China and Japan: Data from the GBD Study 1990-2016.

Stroke is the first and fourth leading cause of death in China and Japan, respectively. Physical inactivity was suggested to be one of the most important risk factors for stroke mortality. Therefore, this study aimed to assess long-term trends in stroke mortality attributable to low physical activity (LPA) in China and Japan during the period 1990-2016. Mortality data were obtained from the Global Burden of Disease Study 2016 (GBD 2016) and were analyzed with an age-period-cohort method. The age-standardized mortality rates (ASMRs) showed declining trends for LPA-attributable stroke mortality. The overall net drift per year was -1.3% for Chinese men, -2.9% for Chinese women, -3.9% for Japanese men, and -5.6% for Japanese women. In both countries, the local drift values were below zero in all age groups. The longitudinal age curves of LPA-attributable stroke mortality were higher in men than in women in all age groups. The period and cohort rate ratios showed similar downward patterns for both sexes, with a faster decline for women than for men. However, the physically active population is still small in both countries. Therefore, policymakers should further promote physical activity as one of the most recommended effective strategies in stroke prevention.

Relative Income Deprivation and All-Cause Mortality in Japan: Do Life Priorities Matter?

BACKGROUND/PURPOSE: Relative deprivation (RD) is proposed to affect health through psychosocial stress stemming from upward social comparisons. This study hypothesized that prioritizing values, such as social engagement and personal growth (as opposed to prioritizing work), would inoculate against the toxic effects of upward social comparisons. METHODS: Prospective data of 9,533 subjects (4,475 men and 5,058 women) participating in the Komo-Ise study answering a baseline questionnaire in 1993 and a follow-up survey in 2000 were analyzed. Associations between RD-using Yitzhaki Index (YI) and Income Rank (IR)-and mortality were evaluated using Cox proportional-hazard regression models. At follow-up, people were also asked about what they prioritized in life: work, social engagement, or personal growth. RESULTS: 1,168 deaths (761 men and 407 women) occurred during follow-up (to the end of 2011). Controlling for sociodemographic factors, the hazard ratio (HR) for mortality was 1.22 (95% confidence interval [CI] = 1.08-1.38) per a standard deviation (SD) increase in YI and 1.18 (95% CI = 1.03-1.35) per an SD decrease in IR. Life priorities (LP) were not statistically significantly associated with mortality. In women, the interaction between LP and YI was statistically significant. In fully adjusted models, women who endorsed only work as very important in their lives had a 2.66 (95% CI = 1.23-5.77) times higher HR for mortality per SD increase in YI compared to women who valued social engagement/personal growth. An interaction between LP and RD was not found in men. CONCLUSIONS: Increased relative income deprivation was associated with a higher risk of all-cause mortality independently of absolute income. Focusing on social engagement/personal growth (as opposed to work) appears to inoculate women against the toxic effects of relative deprivation.

Age, period, cohort trends of suicide in Japan and Korea (1986-2015): A tale of two countries.

Japan and South Korea have among the highest suicide rates in the world. However, the age, gender, and time trends in each country differ substantially. Age-Period-Cohort (APC) analysis of suicide rates was conducted to better understand these differences. Using age- and gender-specific data on suicide between 1986 and 2015 in Japan and Korea, we implemented APC analysis to decompose the country-specific trends into age, calendar period, and birth cohort effects. APC analysis revealed three trends: (1) there was a sharp increase in suicide around retirement age in Korea but not in Japan (age effect); (2) there was a dramatic increase in suicide during the three decades of observation in Korea (period effect) whereas rates were more stable in Japan; and (3) the post-War generation in Japan (including baby boomer) had lower rates of suicide compared to generations born before 1916 or after 1961 (birth cohort effect), whereas suicide rate has increased linearly in each generation in Korea. Although Japan & Korea share high suicide rates, our APC analysis suggests divergent causes underlying these trends. Japanese suicide rates plateaued among the cohorts who experienced the post-War rapid economic growth (women born in 1951-1956 and men born in 1916-1961) (birth cohort effect) due to a strong social safety net for this cohort, while suicide rates in Korea continue to rise with each generation and is particularly elevated in post-retirement age. Japan and Korea need to pay more attention to suicide prevention in more recent birth cohorts.

Age-Period-Cohort Analysis of Stroke Mortality Attributable to High Sodium Intake in China and Japan.

Background and Purpose- The aim of this study is to assess the long-term trends in stroke mortality attributable to high sodium intake in China and Japan during the period 1990 to 2016. Methods- The mortality data were obtained from the GBD study (Global Burden of Disease) 2016 and were analyzed using an age-period-cohort method. Results- The age-standardized mortality rates showed declining trends for high sodium intake-related stroke mortality. The overall net drifts per year were -3.1% for Chinese men and -5.0% for Chinese women; and -4.6% for Japanese men and -5.7% for Japanese women. The local drift values were below zero in all age groups for both sexes in both countries, and all local drift values of female participants were below their counterparts of male participants. The longitudinal age curves of high sodium intake-attributable stroke mortality increased rapidly for both sexes in China, whereas those of Japanese were slowly rising. The period and cohort rate ratios were found to have similar downward patterns for both sexes in both countries, with a quicker decline for women than for men (significantly with P<0.05 for all). Conclusions- The age-standardized mortality rates, the period effect and the cohort effect of stroke mortality attributable to high sodium intake in China and Japan have been declining in both sexes and all age groups from 1990 to 2016. Consequently, sodium-reduction strategies are of low cost and effective for the prevention of stroke. It is necessary to educate the nation with the correct knowledge on healthy diet and techniques to reduce salt consumption.

Cardiovascular disease mortality in relation to physical activity during adolescence and adulthood in Japan: Does school-based sport club participation matter?

We examined potential associations of sport club participation during adolescence and sports-related physical activity during adulthood with mortality from cardiovascular diseases (CVD) in a Japanese population. Between 1988 and 1990, 29,526 men and 41,043 women aged 40-79 years responded to a questionnaire including questions about the frequency of sports participation at baseline and sport club participation during junior/senior high school. Subjects were followed-up until the end of 2009, and 4230 cardiovascular deaths (870 CHD, 1859 stroke) were identified. Cox proportional-hazard regression models were used to estimate hazard ratios (HR). During the first-two thirds of the follow-up - where the proportional hazards assumption was met - the multivariate-adjusted HR (95% confidence interval) for total CVD mortality was 0.77 (0.61-0.98) among men and 0.82 (0.61-1.10) among women who were physically active at baseline (≥5 h/week versus 1-2 h/week). The corresponding HRs for coronary heart disease (CHD) mortality were 0.65 (0.39-1.07) and 0.40 (0.17-0.91), respectively. The combined associations of sports participation during adulthood and adolescence were also examined. Among men who participated in sports for ≥5 h/week at baseline, the multivariate-adjusted HR for those who also engaged in sport club activities during adolescence was 0.89 (0.61-1.30) for total CVD mortality and 0.24 (0.08-0.71) for CHD mortality when compared to non-participants. Among women, no statistically significant differences were found between sport club participants and non-participants. In conclusion, participating in sport clubs during adolescence might lead to a more pronounced risk-reduction for CHD mortality among men who also participate in sport activities during adulthood.

Associations of relative deprivation and income rank with depressive symptoms among older adults in Japan.

INTRODUCTION: Income is hypothesized to affect health not just through material pathways (i.e., the ability to purchase health-enhancing goods) but also through psychosocial pathways (e.g., social comparisons with others). Two concepts relevant to the psychosocial effects of income are: relative deprivation (for example expressed by the Yitzhaki Index, measuring the magnitude of difference in income among individuals) and Income Rank. This study examined whether higher relative deprivation and lower income rank are associated with depressive symptoms in an older population independently of absolute income. METHOD: Using cross-sectional data of 83,100 participants (40,038 men and 43,062 women) in the Japan Gerontological Evaluation Study (JAGES), this study applied multiple logistic regression models to calculate the odds ratios (OR) of depression associated with relative deprivation/Income Rank. The Japanese Geriatric Depression Scale (GDS-15) was used to assess depressive symptoms, and subjects with a score of ≥5 were categorized as depressed. Reference groups for calculating the Yitzhaki Index and income rank were constructed based on same gender, age-group, and municipality of residence. RESULTS: The findings indicated that after controlling for demographic factors, each 100,000 yen increase in relative deprivation and 0.1 unit decrease in relative rank was associated with a 1.07 (95% CI = 1.07, 1.08) and a 1.15 (95% CI = 1.14, 1.16) times higher odds of depression, respectively, in men. The corresponding ORs in women were 1.05 (95% CI = 1.05, 1.06) and 1.12 (95% CI = 1.11, 1.13), respectively. After adjustment for other covariates and stratification by income quartiles, the results remained statistically significant. Women in the highest income quartile appeared to be more susceptible to the adverse mental health effects of low income rank, while among men the associations were reversed. Low income rank appeared to be more toxic for the poor. CONCLUSION: Concepts of relative income appear to be relevant for mental health over and above the effects of absolute income.

Health Disparities in Ischaemic Heart Disease Mortality in Hungary From 1970 to 2010: An Age-Period-Cohort Analysis.

BACKGROUND: The objective of this study was to examine long-term trends in rates of ischaemic heart disease (IHD) mortality, a leading cause of mortality in Hungary. The study examined the effects of age, period, and cohort on IHD mortality rates and compared mortality rates between the capital (Budapest) and non-capital counties. METHODS: Data on IHD deaths and population censuses were obtained from the Hungarian Central Statistical Office. Age-period-cohort analysis utilized nine age-group classes for ages 40 to 84 years, eight time periods from 1970 to 2009, and 16 birth cohorts from 1886 to 1969. RESULTS: Age-adjusted IHD mortality rates for men and for women generally increased from 1970 to 1993 and from 1980 to 1999, respectively, decreasing thereafter for both sexes. IHD mortality rates for men and for women from Budapest were lower from 1991 and from 1970, respectively, than corresponding rates in non-capital counties, with the difference increasing after 1999. Age had a more significant influence on mortality rates for women than for men. The period effect increased from 1972 to 1982 and decreased thereafter for men, while the period effect decreased consistently for women from 1972 to 2007. The decline in period effect for both sexes was larger for individuals from the capital than for those from non-capital counties. The cohort effect for both sexes declined from birth years 1890 to 1965, with a steeper decline for individuals from the capital than for those from non-capital counties. CONCLUSIONS: The findings indicate a need for programs in Hungary for IHD prevention, especially for non-capital counties.
