Role of Social Support in the Relationship Between Financial Strain and Frequency of Exercise Among Older Japanese: A 19-year Longitudinal Study.

Background: Previous studies have reported that financial strain has deleterious effects on healthy behaviors. Moreover, social support is expected to mitigate these effects, but few studies have investigated the effects of exercise; thus, the investigation can deepen our understanding of the relationship between social support and physical activity/exercise. We examined the relationship between financial strain and frequency of exercise, and the role of social support in this relationship in old age.
