There is a dearth of empirical research examining how patterns of stability and change in social engagement affect mortality. This study uses social integration theory within a life course framework to examine trajectories of social engagement over time and how those patterns relate to mortality.
Data are drawn from the Americans' Changing Lives survey, a nationally representative panel study, with mortality information spanning from 1986 to 2005.
Even after controlling for known predictors of mortality, membership in a trajectory of high and slightly increasing social engagement was related to lower risk of mortality. Sociodemographic, health condition, and health behavior variables mediated the impact of the other social engagement trajectories on mortality.
Findings suggest the importance of maintaining high levels of social engagement over time for the health of older adults.

    • "A second limitation is our assessment of social support trajectories. Although our trajectory analyses represent an advance over static baseline measures of social support, discrete trajectory classification " ignores the interindividual heterogeneity around each trajectory class " (Thomas, 2012:562). By clustering individual trajectories, the GMM procedure necessarily restricts our interpretation to differences in social support trajectory classes. "

    ABSTRACT: Although numerous studies of non-Hispanic whites and blacks show that social integration and social support tend to favor longevity, it is unclear whether this general pattern extends to the Mexican American population. Building on previous research, we employed seven waves of data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly to examine the association between perceived social support trajectories and the all-cause mortality risk of older Mexican Americans. Growth mixture estimates revealed three latent classes of support trajectories: high, moderate, and low. Cox regression estimates indicated that older Mexican American men in the low support trajectory tend to exhibit a higher mortality risk than their counterparts in the high support trajectory. Social support trajectories were unrelated to the mortality risk of older Mexican American women. A statistically significant interaction term confirmed that social support was more strongly associated with the mortality risk of men.

    • "One important aspect of volunteering is social engagement or participating in social life. Social engagement among older people has been well recognised as a predictor of health status, cognitive functioning and mortality (Thomas, 2012). However, Anderson et al. (2014) have reviewed many studies which point to the wellbeing benefits of volunteering over and above those of social engagement. "

    ABSTRACT: Social policy applications of 'active ageing' ideals have recently focussed on volunteering as a beneficial and valuable contribution that older people can make to their communities. In this paper we draw attention to the positive and negative effects of a general imperative to contribute. Understanding the benefits of contribution in terms of the moral force of reciprocity recognises that older people do need and want to contribute to society and these contributions are beneficial for their sense of identity and wellbeing. However, older people vary greatly in their health, financial resources, and social networks and should not be seen as a homogenous group whose members must contribute in the same way. A policy focus on the imperative to contribute as a participating citizen can be oppressive and lead to withdrawal from social engagement by those who are the most in need of support to participate. Priorities for social and organisational policies must include support for the many ways older people are able to be involved in their communities and to provide structures necessary to support their preferences. A focus on individual responsibility for active engagement in society, which does not take account of individual circumstances or past contributions, can be harmful. Copyright © 2015 Elsevier Inc.

    ABSTRACT: Abstract The SilverSneakers fitness program is a health plan benefit for Medicare beneficiaries that provides older adults with fitness center membership, customized group exercise classes, and a supportive social environment that promotes socialization among participants. This study evaluated the impact of the SilverSneakers program on physical and emotional health and activities of daily living (ADLs). A quasi-experimental retrospective analysis compared annual survey responses from SilverSneakers members (treatment N=5586) to a matched national random sample of Medicare Advantage organization beneficiaries (comparison N=22,344) in Cohort 10 of the Medicare Health Outcomes Survey. Matching was performed based on 6 demographic and 6 disease status variables. Survey responses from 2007 and 2009 were evaluated using categorical and logistic regression analysis. The treatment group showed significantly better physical and emotional health and lower impairment in both 2007 and 2009, less impairment for 4 of 6 ADLs in 2007, and all 6 in 2009, and a higher average number of days of good health within the prior month for both years. Three-year longitudinal analyses indicated a significantly more favorable survey response trend for the treatment group for nearly all measures of health and ADLs. Members who exercised less frequently had poorer health and functioning. Overall, participation in the SilverSneakers program was associated with more favorable overall physical and social/emotional health status and fewer activity impairments, suggesting that the provision of senior-oriented group fitness programs may be a valuable approach to improve quality of life and reduce the burden associated with declining health and functioning as older adults age.
