This study examined the longitudinal reciprocal effects between health and social support in older adults’ relationships with their children and friends. Data are from the 2006 and 2010 waves of the Health and Retirement Study ( N = 3,760). We focused on three specific aspects of social support: frequency of contact, positive interactions, and negative interactions. We used autoregressive cross-lagged models to examine the bidirectional effects between social support and health. When the bidirectional effects between health and social support were simultaneously examined, the longitudinal effect of social support on health was not significant. In contrast, older adults’ poor health was associated with decreased contact and decreased positive interactions with friends as well as with increased negative interactions with their adult children and friends. The findings suggest that older adults’ poor health has a negative impact on their social relationships and that such effect surpasses the impact of social relationships on health.

Little is known about the cross-sectional or longitudinal relationships between body weight and health at older ages. Using multilevel modeling analyses, this study examined the trajectories of body mass index (BMI), chronic health conditions (CHC), and functional disability (FD); factors associated with the trajectories; and the relationships between the trajectories. The sample of elders aged 65 and older participated in the Americans Changing Lives longitudinal study. Participants showed decreasing BMI and increasing CHCand FD with time. Current smokers presented lowerBMI at Wave 1 and showed a slower decrease inBMIover time than those who never smoked. Obesity was associated with more CHC and greater FDatWave 1 but did not influence their changes. Elders who experienced a slower decrease in BMI showed a slower increase in CHC and FD; the change in health was not related to the change in BMI.
