Researchers generally recognize that racial identification may shift over the life course. However, there is less consensus about the prevalence of these shifts. Previous estimates suggest as many as 6% of Americans shift their racial identity. Using administrative data on Social Security applications from 1984 to 2007, we quantify the magnitude and direction of shifts in racial and ethnic self-identification among Black, White, Asian, American Indian, and Hispanic members of the “Greatest Generation,” those born between 1901 and 1927 (N = 410,388). Approximately 9,274 (2.3%) persons in this dataset changed their racial or Hispanic identity, with distinct patterns of change for racial-ethnic subgroups. Overall, the most common shift was from a non-White identity to a non-Hispanic White identity. We then link to the 1940 Census to investigate whether social status in youth and young adulthood predicts a shift in identity in later life, and we find a positive and significant association between socioeconomic status in early life and a shift from non-White to non-Hispanic White identity. These systematic patterns would be unlikely if these shifts were due entirely to measurement error. We conclude the prevalence of racial fluidity is itself contingent, varying across time and cohort with response to racial climate, events in greater society, and social position.

Abstract Background Cardiovascular diseases are an important component of the multi-morbidity syndrome which is associated with negative health outcomes resulting in a major societal economic burden. An objective way to assess multi-morbidity is to calculate a frailty index based on medical deficit accumulation. Late-life frailty has been validated to predict mortality, but little is known about the association between life-course frailty and cardiovascular health in later-life. Purpose To study the association between life-course frailty and later-life heart size and function using data from the world's longest running birth cohort with continuous follow-up. Methods A 45-deficit frailty index (FI) was calculated at 4 age-intervals across the life-course (0 to 16 years old, 19 to 44 years old, 45 to 54 years old and 60 to 64 years old) in participants from the UK 1946 Medical Research Council (MRC) National Survey of Heath and Development (NSHD) birth cohort. The life-course frailty indices (FI0_16, FI19_44, FI45_54 and FI60_64) reflect the cumulative medical deficits at the corresponding age-intervals. They were used to derive FImean and FIsum reflecting overall-life frailty. The step change in deficit accumulation between age-intervals was also calculated (FI2-1, FI3-1, FI4-1, FI3-2, FI4-2, FI4-3). Echocardiographic data at 60–64 years provided: E/e' ratio, ejection fraction (EF), myocardial contraction fraction index (MCFi) and left ventricular mass index (LVmassi). Generalized linear mixed models with gamma distribution and log link assessed the association between FIs and echo parameters after adjustment for sex, socio-economic position and body mass index. Results 1.805 NSHD participants were included (834 male). Accumulation of a single deficit had a significant impact (p<0.0001 to p<0.049) on LVmassi and MCFi in all the life-course FIs and overall FIs. LVmassi increased by 0.89% to 1.42% for the life-course FIs and by 0.36%/1.82% for FIsum and FImean respectively. MCFi decreased by 0.62% to 1.02% for the life-course FIs and by 0.33%/ 1.04%. for FIsum and FImean respectively. One accumulated deficit translated into higher multiplicative odds (13.2 for FI60-64, 2.1 for FI4-1, 75.4 for FI4-2 and 78.5 for FI4-3) of elevated filling pressure (defined as E/e' ratio >13, p<0.0.005 to p<0.02).A unit increase in frailty decreased LV EF (%) by 11%/12% for FI45-54 and FI60-64 respectively, by 10% to 12% for FI2-1, FI3-1, FI4-1 and FI4-2, and 4%/15% for FIsum and FImean respectively (p<0.0014 to p<0.044). Conclusion Frailty during the life-course, overall life-frailty and the step change in deficit accumulation is associated with later-life cardiac dysfunction. Frailty strain appears to have its greatest impact on pathological myocardial hypertrophy (high LVmassi and low MCFi) potentially paving the way to later-life systolic or diastolic dysfunction in susceptible individuals.

Abstract Background Existing evidence suggests that there is an association between body size and prevalent Benign Prostatic Hyperplasia (BPH)-related outcomes and nocturia. However, there is limited evidence on the association between body size throughout the life-course and incident BPH-related outcomes. Methods Our study population consisted of men without histories of prostate cancer, BPH-related outcomes, or nocturia in the intervention arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) (n = 4710). Associations for body size in early- (age 20), mid- (age 50) and late-life (age ≥ 55, mean age 60.7 years) and weight change with incident BPH-related outcomes (including self-reported nocturia and physician diagnosis of BPH, digital rectal examination-estimated prostate volume ≥ 30 cc, and prostate-specific antigen [PSA] concentration > 1.4 ng/mL) were examined using Poisson regression with robust variance estimation. Results Men who were obese in late-life were 25% more likely to report nocturia (Relative Risk (RR): 1.25, 95% Confidence Interval (CI): 1.11–1.40; p-trendfor continuous BMI < 0.0001) and men who were either overweight or obese in late-life were more likely to report a prostate volume ≥ 30 cc (RRoverweight: 1.13, 95% CI 1.07–1.21; RRobese: 1.10, 95% CI 1.02–1.19; p-trendfor continuous BMI = 0.017) as compared to normal weight men. Obesity at ages 20 and 50 was similarly associated with both nocturia and prostate volume ≥ 30 cc. Considering trajectories of body size, men who were normal weight at age 20 and became overweight or obese by later-life had increased risks of nocturia (RRnormal to overweight: 1.09, 95% CI 0.98–1.22; RRnormal to obese: 1.28, 95% CI 1.10–1.47) and a prostate volume ≥ 30 cc (RRnormal to overweight: 1.12, 95% CI 1.05–1.20). Too few men were obese early in life to examine the independent effect of early-life body size. Later-life body size modified the association between physical activity and nocturia. Conclusions We found that later-life body size, independent of early-life body size, was associated with adverse BPH outcomes, suggesting that interventions to reduce body size even late in life can potentially reduce the burden of BPH-related outcomes and nocturia.

Abstract Despite the well-established benefits of social participation for individuals and communities, little is known about how it varies throughout the life course. Drawing upon data collected between 1957 and 2011 by the Wisconsin Longitudinal Study (22,023 observations from a cohort of 6,627), this study provides four valuable results. One, I find evidence of five distinct social participation trajectories between the ages of 35 and 71; the majority of which demonstrate social disengagement over time. Two, these participation declines are primarily attributable to changes in meeting friends and group exercise activity. Three, the most pronounced activity differences separating those in more favorable and unfavorable participation trajectories are cultural event attendance and voluntary group membership. Lastly, I identify particular high school activities that are associated with social participation decades later. In total, these results highlight heterogeneity among different types of social activities, and underscore the possible consequences of membership decisions made in early adulthood.

School districts in the United States are required to monitor the overrepresentation of students of color in special education, yet recent studies have challenged these trends and suggest students of color may be underrepresented for services guaranteed under federal law. Missing in many of these discussions on disproportionality are the needs of Asian Americans and Pacific Islanders (AAPIs), a group consistently underrepresented in special education. Previous studies, however, do not examine the vast heterogeneity in experiences among AAPIs and how special education trends may differ across AAPI ethnic subgroups. Using longitudinal data on 10 cohorts of 42,807 total kindergartners from a school district over a 10-year period, this study probes deeper into underrepresentation by disaggregating participation trends and the timing of services for 11 AAPI ethnic subgroups. Results indicate that most AAPI student groups are underrepresented in special education and first receive services later than White peers. These patterns remain even after accounting for student background, level of acculturation, and school fixed effects.

Until recently the sex life of older people was more or less invisible in family and gerontological research. This chapter contributes to breaking this silence by focusing on the role and meaning of sex in intimate relationships in later life. Based on biographical case studies, the chapter investigates how sexual norms have changed over the life course of contemporary cohorts of older people and how they have experienced this change. The chapter considers sexual intimacy as part of new intimate relationships established late in life and questions the persistent assumption that older people who date are primarily looking for companionate relationships. It is shown that older people’s ideas about sex are deeply embedded in an ideology of love, where sex tends to be viewed as a natural part of a loving relationship, while sex outside of a loving relationship – also in a loveless marriage – is frowned on.

(1) Background: Despite having consistently lower rates of obesity than other ethnic groups, Asian Americans (AAs) are more likely to be identified as metabolically obese, suggesting an ethnic-specific association between BMI and cardiometabolic outcomes. The goal of this study was to provide an estimate of metabolic syndrome (MetS) prevalence among AAs using national survey data and to compare this rate to that of non-Hispanic Whites (NHWs) over the BMI continuum. (2) Methods: Using the NHANES 2011–2016 data, we computed age-adjusted, gender-specific prevalence of MetS and its individual components for three BMI categories. Furthermore, we conducted multivariate binary logistic regression to examine the risk of MetS in AAs compared to NHWs, controlling for sociodemographic and lifestyle factors. The analysis sample consisted of 2121 AAs and 6318 NHWs. (3) Results: Among AAs, the prevalence of MetS and its components increased with higher BMI levels, with overall prevalence being 5.23% for BMI < 23, 38.23% for BMI of 23–27.4, and 77.68% for BMI ≥ 27.5 in men; and 18.61% for BMI < 23, 47.82% for BMI of 23–27.4, and 67.73% for BMI ≥ 27.5 in women. We also found that for those with a BMI > 23, AAs had a higher predicted risk of MetS than their NHW counterparts of the same BMI level, in both men and women. (4) Conclusions: Our findings support the use of lower BMI ranges for defining overweight and obesity in Asian populations, which would allow for earlier and more appropriate screening for MetS and may better facilitate prevention efforts.

Aim: To study the association between the life course accumulation of health deficits and later life heart size and function using data from the 1946 National Survey of Heath and Development (NSHD) British birth cohort, the longest running birth cohort with continuous follow up in the world. Methods and Results: A multidimensional health deficit index (DI) looking at 45 health deficits was serially calculated at 4 time periods of the life course in NSHD participants (0 to 16, 19 to 44, 45 to 54 and 60 to 64 years), and from these the mean and total DI for the life course was derived (DImean, DIsum). The step change in deficit accumulation from one time period to another was also calculated. Echocardiographic data at 60-64 years provided: ejection fraction (EF), left ventricular mass indexed to body surface area (LVmassi, BSA), myocardial contraction fraction indexed to BSA (MCFi) and E/e. Generalized linear models assessed the association between DIs and echocardiographic parameters after adjustment for sex, socioeconomic position and body mass index. 1,375 NSHD participants were included (46.47% male). For each single new deficit accumulated at any one of the 4 time periods of the life course, LVmassi increased by 0.91 to 1.44% (p<0.013), while MCFi decreased by 0.6 to 1.02% (p<0.05 except at 45 to 54 years). One unit increase in DI at age 45 to 54 and 60 to 64 decreased LV EF by 11 to 12% (p<0.013). A single deficit step change occurring between 60-64 years and one of the earlier time periods, translated into significantly higher odds (2.1 to 78.5, p<0.020) of elevated LV filling pressure defined as E/e>13. Conclusion: The accumulation of health deficits at any time period of the life course associates with a maladaptive cardiac phenotype in older age, dominated by myocardial hypertrophy and poorer function. The burden of health deficits appears to strain the myocardium potentially leading to future cardiac dysfunction. Keywords: frailty; cardiovascular disease; ejection fraction; left ventricular mass index; myocardial contraction fraction; E/e.

Socio-economic position (SEP) is associated with all-cause mortality across all stages of the life course; however, it is valuable to distinguish at what time periods SEP has the most influence on mortality. Our aim was to investigate whether the effect of SEP on all-cause mortality accumulates over the life course or if some periods of the life course are more important. Our study population were from the Uppsala Birth Cohort Multigenerational Study, born 1915–29 at Uppsala University Hospital, Sweden. We followed 3,951 men and 3,601 women who had SEP at birth available, during childhood (at age ten), in adulthood (ages 30–45) and in later life (ages 50–65) from 15 September 1980 until emigration, death or until 31 December 2010. We compared a set of nested Cox proportional regression models, each corresponding to a specific life course model (critical, sensitive and accumulation models), to a fully saturated model, to ascertain which model best describes the relationship between SEP and mortality. Analyses were stratified by gender. For both men and women the effect of SEP across the life course on all-cause mortality is best described by the sensitive period model, whereby being advantaged in later life (ages 50–65 years) provides the largest protective effect. However, the linear accumulation model also provided a good fit of the data for women suggesting that improvements in SEP at any stage of the life course corresponds to a decrease in all-cause mortality.

Older adults are particularly prone to function-limiting health issues that adversely affect their well-being. Previous work has identified factors from across the life course –childhood socio-economic status, childhood cognitive ability and education – that predict later-life functional outcomes. However, the independence of these contributions is unclear as later-in-the-life-course predictors are themselves affected by earlier ones. The present study capitalised on the recent linkage of the Scottish Mental Survey 1947 with the Scottish Longitudinal Study, using path analyses to examine the direct and indirect associations between life-course predictors and the risk of functional limitation at ages 55 (N = 2,374), 65 (N = 1,971) and 75 (N = 1,534). The odds of reporting a function-limiting long-term condition increased across later life. At age 55, reporting a functional limitation was significantly less likely in those with higher childhood socio-economic status, higher childhood cognitive ability and higher educational attainment; these associations were only partly mediated by other predictors. At age 65, adult socio-economic status emerged as a mediator of several associations, although direct associations with childhood socio-economic status and childhood cognitive ability were still observed. At age 75, only childhood socio-economic status and adult socio-economic status directly predicted the risk of a functional limitation, particularly those associated with disease or illness. A consistent pattern and direction of associations was observed with self-rated health more generally. These results demonstrate that early-life and adult circumstances are associated with functional limitations later in life, but that these associations are partly a product of complex mediation between life-course factors.
