Earlier-life individual and spatial socioeconomic conditions and later-life physical activity.

Abstract

This study investigated the association between earlier-life (before age 16) individual and spatial socioeconomic conditions and later-life (mean age 61) physical activity (PA), and the role of later-life characteristics. Contemporary and historical Census data as well as three bi-annual waves of nationally representative panel data from the Understanding America Study (N=1,981) were used. Multilevel growth curve models were estimated to address the research questions. Father's education in respondents' earlier life was positively associated with light and moderate PA in respondents' later life. Growing up in a higher-poverty area was negatively associated with moderate and vigorous later-life PA. Findings underscore the long-term ramifications of earlier-life circumstances for later-life PA. Consideration should be given to socioeconomic conditions at both individual and spatial levels over the life course to promote PA at older ages.
