Socioeconomic status and health behaviors as predictors of changes in self-rated health among older persons in Israel.

Abstract

There is a considerable body of scientific knowledge about factors associated with self-rated health (SRH), a common measure of health status. However, less is known about the factors associated with changes in SRH over time. In order to fill this gap, the aim of the current study was to examine a combination of socioeconomic, psychosocial, and health behaviour variables in explaining changes in SRH among older adults. The study used data from two time periods in Israel of the Survey of Health, Aging and Retirement in Europe (SHARE) to analyse the predictive contribution of Time 1 socioeconomic, psychosocial and behavioural variables and changes in these variables over time to changes in SHR. The sample included 1,549 older persons interviewed at baseline (years 2009-2010) and four years later (year 2013). Using bivariate and multivariate regression models, the findings show that 26 percent and 23 percent of the participants reported either improvement or a deterioration in their SRH, respectively. Decline in SRH was predicted by a combination of Time 1 socioeconomic (subjective assessment of a household's ability to make ends meet), psychosocial (QoL and in trust in people), and behavioural factors (moderate physical activity) and decline in these factors over time. The findings demonstrate that changes in those variables make an additional significant contribution for explaining changes in SRH. The findings suggest that in addition to identification of low SES, poor psychosocial and behavioural factors as risk factors to poor SRH changes in these factors should be monitored among older populations.
