Explaining the cross-national variation in the relationship between religious organization membership and civic organization participation.

We examine the relationship between belonging to religious organizations and participating in nonreligious civic organizations through use of a large international sample of individuals. Moreover, we assess how this relationship is contingent upon social context, that is Protestant percentage, economic condition, and democratic level of a nation. Using data from the sixth wave of the World Values Survey (2010-2014), our multilevel analyses reveal that religious organization members are more likely than non-members to participate in civic organizations cross-nationally. In addition, societal context is found to moderate this association. Specifically, the differences between religious organization members and non-members in this regard are larger in societies characterized by a smaller Protestant population, poorer economic condition, and nondemocratic institutions. We discuss our findings in light of theories on religion, social capital, and social context.

Caregiver Burden, Care Recipient Depressive Symptomology, and Social Exchange: Does Race Matter?

Informal caregivers play a vital role in supporting seriously ill patients. However, informal caregiving is burdensome and can lead to negative health outcomes for the caregiver and the care recipient. The study's aim was to evaluate relationships among caregiver burden, care recipient depressive symptomology, and race. Guided by the social exchange perspective, we examined cross-sectional dyadic data from the National Long-Term Care Survey (N = 1279). Using ordinal logistic regression, we found that higher caregiver-reported objective burden was associated with higher care recipient depressive symptoms ( P < .05), an association that was stronger for blacks. Interestingly, despite significant levels of objective burden, there was an association between lower depressive symptoms in black care recipients when there was an exchange of the social good "helpful company" with a caregiver. These findings illustrate the importance of supporting reciprocal exchange as a promising component of maintaining balanced caregiver-care recipient relationships among black older adults and their informal caregivers.

Population differences in associations of serotonin transporter promoter polymorphism (5HTTLPR) di- and triallelic genotypes with blood pressure and hypertension prevalence.

Based on prior research finding the 5HTTLPR L allele associated with increased cardiovascular reactivity to laboratory stressors and increased risk of myocardial infarction, we hypothesized that the 5HTTLPR L allele will be associated with increased blood pressure (BP) and increased hypertension prevalence in 2 large nationally representative samples in the United States and Singapore. METHODS: Logistic regression and linear models tested associations between triallelic (L'S', based on rs25531) 5HTTLPR genotypes and hypertension severity and mean systolic and diastolic blood pressure (SBP and DBP) collected during the Wave IV survey of the National Longitudinal Study of Adolescent to Adult Health (Add Health, N=11,815) in 2008-09 and during 2004-07 in 4196 Singaporeans. RESULTS: In US Whites, L' allele carriers had higher SBP (0.9 mm Hg, 95% CI=0.26-1.56) and greater odds (OR=1.23, 95% CI=1.10-1.38) of more severe hypertension than those with S'S' genotypes. In African Americans, L' carriers had lower mean SBP (-1.27mm Hg, 95% CI=-2.53 to -0.01) and lower odds (OR = 0.78, 95% CI=0.65-0.94) of more severe hypertension than those with the S'S' genotype. In African Americans, those with L'L' genotypes had lower DBP (-1.13mm Hg, 95% CI=-2.09 to -0.16) than S' carriers. In Native Americans, L' carriers had lower SBP (-6.05mm Hg, 95% CI=-9.59 to -2.51) and lower odds of hypertension (OR = 0.34, 95% CI=0.13-0.89) than those with the S'S' genotype. In Asian/Pacific Islanders those carrying the L' allele had lower DBP (-1.77mm Hg, 95% CI=-3.16 to -0.38) and lower odds of hypertension (OR = 0.68, 95% CI=0.48-0.96) than those with S'S'. In the Singapore sample S' carriers had higher SBP (3.02mm Hg, 95% CI=0.54-5.51) and DBP (1.90mm Hg, 95% CI=0.49-3.31) than those with the L'L' genotype. CONCLUSIONS: These findings suggest that Whites carrying the L' allele, African Americans and Native Americans with the S'S' genotype, and Asians carrying the S' allele will be found to be at higher risk of developing cardiovascular disease and may benefit from preventive measures.

Personality and the Intergenerational Transmission of Educational Attainment: Evidence from Germany.

Research based in the United States, with its relatively open educational system, has found that personality mediates the relationship between parents' and child's educational attainment and this mediational pattern is especially beneficial to students from less-educated households. Yet in highly structured, competitive educational systems, personality characteristics may not predict attainment or may be more or less consequential at different points in the educational career. We examine the salience of personality in the educational attainment process in the German educational system. Data come from a longitudinal sample of 682 17 to 25 year-olds (54% female) from the 2005 and 2015 German Socio-Economic Panel (SOEP). Results show that adolescent personality traits-openness, neuroticism, and conscientiousness-are associated with educational attainment, but personality plays a negligible role in the intergenerational transmission of education. Personality is influential before the decision about the type of secondary degree that a student will pursue (during adolescence). After that turning point, when students have entered different pathways through the system, personality is less salient. Cross-national comparisons in a life course framework broaden the scope of current research on non-cognitive skills and processes of socioeconomic attainment, alerting the analyst to the importance of both institutional structures and the changing importance of these skills at different points in the life course.

Sex Differences in Associations Between Subjective Social Status and C-Reactive Protein in Young Adults.

OBJECTIVE: In middle-aged and older samples, perceived subjective socioeconomic status (SSS) is a marker of social rank that is associated with elevated inflammation and cardiovascular disease risk independent of objective indicators of SES (oSES). Whether SSS is uniquely associated with elevated inflammation during young adulthood and whether these linkages differ by sex have not been studied using a nationally representative sample of young adults. METHODS: Data came from the National Longitudinal Study of Adolescent to Adult Health. At Wave IV, young adults aged mostly 24 to 32 years reported their SSS, oSES, and a range of covariates of both SES and elevated inflammation. Trained fieldworkers assessed medication use, body mass index, and waist circumference, and also collected bloodspots from which high-sensitivity C-reactive protein (hs-CRP) was assayed. The sample size for the present analyses was n = 13,236. RESULTS: Descriptive and bivariate analyses revealed a graded association between SSS and hs-CRP (b = -0.072, standard error [SE] = 0.011, p < .001): as SSS declined, mean levels of hs-CRP increased. When oSES indicators were taken into account, this association was no longer significant in women (b = -0.013, SE = 0.019, p = .514). In men, a small but significant SSS-hs-CRP association remained after adjusting for oSES indicators and additional potential confounders of this association in the final models (b = -0.034, SE = 0.011 p = .003; p < .001 for the sex by SSS interaction). CONCLUSIONS: SSS is independently associated with elevated inflammation in young adults. The associations were stronger in men than in women. These data suggest that subjective, global assessments of social rank might play a role in developing adverse health outcomes.

Parental and adolescent health behaviors and pathways to adulthood.

This paper examines associations among parental and adolescent health behaviors and pathways to adulthood. Using data from the National Longitudinal Study of Adolescent to Adult Health, we identify a set of latent classes describing pathways into adulthood and examine health-related predictors of these pathways. The identified pathways are consistent with prior research using other sources of data. Results also show that both adolescent and parental health behaviors differentiate pathways. Parental and adolescent smoking are associated with lowered probability of the higher education pathway and higher likelihood of the work and the work & family pathways (entry into the workforce soon after high school completion). Adolescent drinking is positively associated with the work pathway and the higher education pathway, but decreases the likelihood of the work & family pathway. Neither parental nor adolescent obesity are associated with any of the pathways to adulthood. When combined, parental/adolescent smoking and adolescent drinking are associated with displacement from the basic institutions of school, work, and family.

Evaluating measurement error in readings of blood pressure for adolescents and young adults.

Readings of blood pressure are known to be subject to measurement error, but the optimal method for combining multiple readings is unknown. This study assesses different sources of measurement error in blood pressure readings and assesses methods for combining multiple readings using data from a sample of adolescents/young adults who were part of a longitudinal epidemiological study based in Cebu, Philippines. Three sets of blood pressure readings were collected at 2-year intervals for 2127 adolescents and young adults as part of the Cebu National Longitudinal Health and Nutrition Study. Multi-trait, multi-method (MTMM) structural equation models in different groups were used to decompose measurement error in the blood pressure readings into systematic and random components and to examine patterns in the measurement across males and females and over time. The results reveal differences in the measurement properties of blood pressure readings by sex and over time that suggest the combination of multiple readings should be handled separately for these groups at different time points. The results indicate that an average (mean) of the blood pressure readings has high validity relative to a more complicated factor-score-based linear combination of the readings.

Self-rated health and C-reactive protein in young adults.

BACKGROUND: Poor self-rated health (SRH) and elevated inflammation and morbidity and mortality are robustly associated in middle- and older-aged adults. Less is known about SRH-elevated inflammation associations during young adulthood and whether these linkages differ by sex. METHODS: Data came from the National Longitudinal Study of Adolescent Health. At Wave IV, young adults aged 24­34 reported their SRH, acute and chronic illnesses, and sociodemographic and psychological characteristics relevant to health. Trained fieldworkers assessed medication use, BMI, waist circumference, and also collected bloodspots from which high-sensitivity CRP (hs-CRP) was assayed. The sample size for the present analyses was N = 13,236. RESULTS: Descriptive and bivariate analyses revealed a graded association between SRH and hs-CRP: Lower ratings of SRH were associated with a higher proportion of participants with hs-CRP >3 mg/L and higher mean levels of hs-CRP. Associations between SRH and hs-CRP remained significant when acute and chronic illnesses, medication use, and health behaviors were taken into account. When BMI was taken into account, the association between SRH and hs-CRP association fully attenuated in females; a small, but significant association between SRH and hs-CRP remained in males. CONCLUSION: Poor SRH and elevated hs-CRP are associated in young adults, adjusting for other health status measures, medication use, and health behavior. In males, SRH provided information about elevated hs-CRP that was independent of BMI. In females, BMI may be a better surrogate indicator of global health and pro-inflammatory influences compared to SRH.

Twentieth-Century Change in the Educational Costs of Adolescent Childbearing.

Although studies observe heterogeneity in the effects of adolescent childbearing on schooling, little is currently known about when this pattern emerged or how it changed across cohorts of women who lived in distinct periods of US history. This article identifies the potential origins of effect heterogeneity in the educational costs of adolescent childbearing and extends recent advances in causal inference to detect group differences in heterogeneity. The analysis applies this approach to four cohorts of women from the National Longitudinal Surveys (NLS) who entered adolescence before, during, and after expansive economic, demographic, and cultural change in the twentieth century. Results suggest that the educational costs of adolescent childbearing, as well as heterogeneity in those costs, increased for women in the latter half of the twentieth century, especially for millennial women born 1980-84. The authors conclude that midcentury social changes fundamentally altered the educational costs of adolescent childbearing for women.

Educational Inequalities in Dual-Function Life Expectancy.

OBJECTIVES: This study investigates educational inequalities in dual functionality, a new concept that captures a combination of physical and cognitive functioning, both of which are important for independent living and quality of life. METHODS: Using data from the Health and Retirement Study and the National Health Interview Survey Linked Mortality Files, we define a measure of dual functionality based on the absence of limitations in activities of daily living and dementia. We estimate age-graded dual-function rates among adults 65+ and age-65 dual-function life expectancy across levels of education stratified by gender. RESULTS: In their mid-60s, 67% of women with less than a high school degree manifest dual functionality as compared with over 90% of women with at least a 4-year college degree. A similar pattern holds among men. These education-based gaps in dual functionality remain across later life, even as dual-function rates decline at older ages. Lower dual-function rates among older adults with less education translate into inequalities of 6.7 and 7.3 years in age-65 dual-function life expectancy between men and women, respectively, with at least a 4-year college degree compared to their counterparts with less than a high school degree. DISCUSSION: Older adults, particularly women, with less than a high school degree are estimated to live a smaller percentage of their remaining years with dual functionality compared with older adults with at least a college degree. These inequalities have implications for the distribution of caregiving resources of individuals, family members, and the broader healthcare community.

Adult Children's Education and Mothers' Psychological Well-Being: Do Adult Children's Problems Mediate This Relationship?

OBJECTIVES: A growing body of literature documents a positive association between adult children's education and older parents' health, and existing studies have identified social support, social influence, and material transfers as factors linking adult children's education and various dimensions of older parents' health. The present study joins this literature by assessing adult children's problems as mechanisms that may underlie disparities in psychological well-being between mothers whose adult children have completed higher and lower levels of education. METHODS: Using 2 waves of longitudinal data collected in 2001-2003 and 2008-2011 from 400 mothers aged 73-85 years at the second wave as part of the Within-Family Differences Study, we examine the role of adult children's problems in mediating the association between adult children's education and mothers' depressive symptoms. RESULTS: Mothers with children who completed post-high school education reported fewer depressive symptoms than mothers whose children all completed high school or less. We found evidence that this relationship was mediated by the proportion of adult children who have experienced physical and emotional problems in the last 5 years. DISCUSSION: This study underscores the importance of considering how resources and risks that affect well-being accumulate both across the life course and across generations. Providing education opportunities to younger generations and enhancing programs that address challenges that low-attaining children may face have the potential to help minimize socioeconomic disparities in psychological well-being among older adults.

Racial-Ethnic Disparities in Dual-Function Life Expectancy.

BACKGROUND: This study develops a new concept, dual functionality, that integrates physical and cognitive function. We use the concept to define a measure of dual-function life expectancy (2FLE) and assess racial-ethnic inequalities in aging. METHODS: Drawing on data from the National Health Interview Survey Linked Mortality Files and the Health and Retirement Study, we define dual functionality as having no limitations in activities of daily living and being free of dementia. We use this measure and Sullivan life tables to estimate age-50 total life expectancy and age-50 2FLE for women and men across 4 racial-ethnic and nativity groups. RESULTS: At ages 50-54, between 79.0% (95% CI: 73.5, 84.5) and 87.6% (95% CI: 84.0, 91.2) of (non-Hispanic) Black, foreign-born Hispanic, and U.S.-born Hispanic women and men remain dual functional as compared with 90.4% (95% CI: 89.3, 91.4) and 91.4% (95% CI: 90.2, 92.5) of (non-Hispanic) White women and men, respectively. These and corresponding racial-ethnic disparities in dual functionality through ages 85 and older translate into substantial inequalities in 2FLE. For instance, the Black-White gap in age-50 2FLE is 6.9 years (95% CI: -7.5, -6.4) for women and 6.0 years (95% CI: -6.6, -5.4) for men. CONCLUSIONS: Black, foreign-born Hispanic, and U.S.-born Hispanic older adults are estimated to live a smaller percentage of their remaining years with dual functionality than White older adults. These results reveal stark racial-ethnic inequalities in aging that have significant implications for quality of life, caregiving, and health needs.

Dual Functionality in Later Life.

Gerontologists have long shown interest in both longevity and quality of life during later life, but considerable debate has ensued as scholars sought to integrate the two. Drawing from research on the topics of exceptional longevity, successful aging, and active life expectancy, we propose the concept of dual functionality to examine how humans reach advanced ages while maintaining physical and cognitive function. Dual functionality refers to being free of both physical and cognitive impairment. The loss of dual functionality challenges social networks to respond to the functional loss and is a harbinger of additional losses. Evidence of change in the percent of the older population maintaining dual functionality would be helpful for evaluating public health policies to aid quality of life during later life. This article is based on the first author's Robert W. Kleemeier Award Lecture at The Gerontological Society of America 2022 Annual Scientific Meeting.

Media consumption and psychological distress among older adults in the United States.

The consumption of news media covering national and global events, particularly those that invoke fear or worry, such as pandemics or terrorist attacks, may affect older adults' mental wellbeing. Using the COVID-19 pandemic as a case study, this research analyzes nationally representative data from older adults in the US to address the following research questions: (1) What is the relationship between COVID-19-based media consumption and psychological distress? (2) Does any relationship between media consumption and psychological distress vary by gender, race/ethnicity, education, and marital status? Results indicate that (1) older adults who closely followed the news about the pandemic scored higher on psychological distress than those following less closely and (2) this relationship was more pronounced among Hispanic older adults. These findings are contextualized in the broader stress process model with a focus on a macro-level stressor and differential exposure and vulnerability resulting in variability in the relationship between the stressor and psychological distress.

Life Course Stressors and Functional Limitations in Later Life Among White, Black, and Hispanic Adults: Deleterious, Hardening, or Benign?

OBJECTIVES: Although striking racial and ethnic disparities in health are manifest during later life, they may be rooted in early-life exposures. Drawing from cumulative inequality theory, we investigate whether life course stressors are associated with the risk of later-life functional limitations and whether this relationship differs by race and ethnicity. METHODS: We utilize longitudinal data from the Health and Retirement Study to test whether child and adult stressors predict trajectories of the occurrence and severity of functional limitations among a diverse sample of older adults. RESULTS: Child and adult stressors are associated with greater occurrence and severity of functional limitations during later life. Mediation analyses reveal the indirect influence of child stressors via adult stressors on occurrence and severity of functional limitations; however, the indirect effects are slightly stronger for Black and Hispanic adults than their White counterparts. DISCUSSION: Child stressors, in and of themselves, do not increase functional limitations among Black and Hispanic people but are associated with greater adult stress exposure, predisposing them to more functional limitations. Results suggest that childhood stressors are associated with distinct social pathways to functional limitations among White, Black, and Hispanic older adults.

Obesity-Related Health Lifestyles of Late-Middle Age Black Americans: The Jackson Heart Study.

INTRODUCTION: This article examines the obesity-related health lifestyle practices of a late-middle age cohort of socioeconomically diverse Black Americans. Black people have the highest prevalence of obesity of any racial group in the U.S. Consequently, the obesity-related health lifestyles of this population is an important topic of investigation, including those in late-middle age for whom there is little data. METHODS: This study employs latent class analysis (LCA) and multinomial logit models to investigate dietary habits, levels of exercise, alcohol use, and smoking. The analysis sample is from the first examination of the Jackson Heart Study (2000‒2004) analyzed in 2021 using LCA. The sample consists of 739 Black men and 1,351 women between the ages of 50 and 64 years. RESULTS: Three classes of lifestyles were found for both genders: healthy diet, unhealthy diet, and unhealthy smokers. For women only, a most healthy lifestyle was added. Major findings are the low levels of physical activity, a clear socioeconomic pattern in healthy lifestyles among Black men and women, and the association of diagnoses of diabetes and cardiovascular disease with healthier lifestyle practices among Black men but not among women. CONCLUSIONS: Obesity-related health lifestyles among late-middle aged Black Americans generally do not converge toward a healthier norm with impending old age. An exception is men who have been diagnosed as having diabetes or heart disease. Otherwise, healthy and unhealthy lifestyle practices remain aligned by social class during this period of the life course.

Mourning in a Pandemic: The Differential Impact of COVID-19 Widowhood on Mental Health.

OBJECTIVES: The death of a spouse is an established predictor of mental health decline that foreshadows worsening physical health and elevated mortality. The millions widowed by COVID-19 worldwide may experience even worse health outcomes than comparable pre-pandemic widows given the particularities of dying, mourning, and grieving during a pandemic defined by protracted social isolation, economic precarity, and general uncertainty. If COVID-19 pandemic bereavement is more strongly associated with mental health challenges than pre-pandemic bereavement, the large new cohort of COVID-19 widow(er)s may be at substantial risk of downstream health problems long after the pandemic abates. METHODS: We pooled population-based Survey of Health, Ageing and Retirement in Europe data from 27 countries for two distinct periods: (1) pre-pandemic (Wave 8, fielded October 2019-March 2020; N = 46,266) and (2) early pandemic (COVID Supplement, fielded June-August 2020; N = 55,796). The analysis used a difference-in-difference design to assess whether a spouse dying from COVID-19 presents unique mental health risks (self-reported depression, loneliness, and trouble sleeping), compared with pre-pandemic recent spousal deaths. RESULTS: We find strong associations between recent spousal death and poor mental health before and during the pandemic. However, our difference-in-difference estimates indicate those whose spouses died of COVID-19 have higher risks of self-reported depression and loneliness, but not trouble sleeping, than expected based on pre-pandemic associations. DISCUSSION: These results highlight that the millions of COVID-19 widow(er)s face extreme mental health risks, eclipsing those experienced by surviving spouses pre-pandemic, furthering concerns about the pandemic's lasting impacts on health.

MODEL IDENTIFICATION AND COMPUTER ALGEBRA.

Multiequation models that contain observed or latent variables are common in the social sciences. To determine whether unique parameter values exist for such models, one needs to assess model identification. In practice analysts rely on empirical checks that evaluate the singularity of the information matrix evaluated at sample estimates of parameters. The discrepancy between estimates and population values, the limitations of numerical assessments of ranks, and the difference between local and global identification make this practice less than perfect. In this paper we outline how to use computer algebra systems (CAS) to determine the local and global identification of multiequation models with or without latent variables. We demonstrate a symbolic CAS approach to local identification and develop a CAS approach to obtain explicit algebraic solutions for each of the model parameters. We illustrate the procedures with several examples, including a new proof of the identification of a model for handling missing data using auxiliary variables. We present an identification procedure for Structural Equation Models that makes use of CAS and that is a useful complement to current methods.

A Note on Algebraic Solutions to Identification.

Algebraic methods to establish the identification of structural equation models remains a viable option. However, sometimes it is unclear whether the algebraic solution establishes identification. One example is when there is more than one way to solve for the parameter, but one way leads to a single value and a second way leads to a function with more than one value. This note proves that one explicit and unique solution is sufficient for model identification even when other explicit solutions permit more than one solution. The results are illustrated with an example. The results are useful to attempts to use algebraic means to address model identification.
