ABSTRACT This study used a life course approach to examine the ways in which childhood socioeconomic status (SES) may account for some of the racial differences in disability in later life. Eight years (5 waves) of longitudinal data from the US Health and Retirement Study (HRS; 1998-2006), a nationally representative sample of community-dwelling Black and White Americans over age 50 (N=14,588), were used in nonlinear multilevel models. Parental education and father's occupation were used to predict racial differences in activities of daily living (ADL) and instrumental activities of daily living (IADL). The role of adult SES (education, income, and wealth) and health behaviors (smoking, drinking alcohol, exercising, and being obese) were also examined and models were adjusted for health conditions (heart problems, diabetes, stroke, hypertension, cancer, lung disease, and arthritis). With the inclusion of childhood SES indicators, racial differences in ADL and IADL disability were reduced. Adult SES and health behaviors mediated some of the relationship between low childhood SES and disability, though low childhood SES continued to be associated with disability net of these. In support of a life course approach, these findings suggest that socioeconomic conditions in early life may have implications for racial differences in disability between older Black and older White adults.

    ABSTRACT: This is the first analysis that demonstrates empirically the likely tie between activities (time spent) and disability (health-related difficulty in activities). We compare trends in activities and disability for Americans ages 55 to 69 in recent years, and assess cross-sectional linkages of activities and disability. Data are from the Health and Retirement Study, a longitudinal survey of community-dwelling U.S. adults. Trends are estimated by mixed-effects regression models (MRMs) with time, age, and time-age interaction predictors. Links of activities and disability also use MRM. For midlife adults, hobbies/leisure and sports/exercise increased, repairs/yard decreased, and several activities had convex patterns; by contrast, disability prevalence was stable. Personal care hours rise with disability, but most activities decline. Activities are more dynamic than disability, and time use is associated with disability. Taken together, the results encourage broader activities in disability measures to capture better disability's scope and dynamics.

    ABSTRACT: Despite persistent schooling-related health disparities in the United States, little is known about the multigenerational effects of schooling on adult health. As expected lifespans increase, direct influences of grandparental schooling on grandchildren's health may become increasingly important. We used multigenerational data spanning 41 years from a national sample of US families to investigate associations of grandparents' educational attainment with global health status, smoking, and obesity in their grandchildren who were aged 25-55 years in 2009. We estimated total effects of grandparental schooling and, by using marginal structural models, we estimated controlled direct effects that were independent of parents' and participants' schooling. Among whites, lower levels of grandparental schooling were monotonically associated with poor health status, current smoking, and obesity in adult grandchildren. There was also evidence suggesting direct effects, which was stronger for poor health status among participants whose highest-educated grandparent lived in the same state. Among blacks, the only association suggesting a total or direct effect of grandparental schooling was for smoking. Despite the relative imprecision of our estimates and possible residual bias, these results suggest that higher levels of grandparental schooling may benefit the health of grandchildren in adulthood, especially among whites. Furthermore, part of those apparent effects, especially for obesity, may not be mediated by parents' and grandchildren's schooling.

    ABSTRACT: The current study examined a 5-year cognitive change in untrained African American and White participants from the Advanced Cognitive Training in Independent and Vital Elderly (ACTIVE) study. Five-year trajectories of memory, reasoning, visual processing speed/useful field of view, digit-symbol substitution, and vocabulary were investigated. Education, health, gender, age, and retest/practice effects were controlled for, and a missing data pattern mixture approach was used to adjust for dropout effects. After considering age, education, health, and gender, being African American uniquely explained 2% to 7% of the variance in cognitive performance. There were virtually no significant race differences in the rates of change. Race-related results in the current study are consistent with previous research suggesting that social advantage factors such as education have a stronger influence on the level of performance than the rate of change. The small remaining effects of being African American on performance levels likely reflect uncontrolled variation in factors like literacy and financial advantage.
