Perception of aging in the relation between sport activity and self-rated health in middle and older age - A longitudinal analysis

BACKGROUND: This study aims to generate more comprehensive knowledge regarding underlying mechanisms of health production in middle and older age by focusing on perception of aging in the relation between sport activity and self-rated health. More differentiated information can be generated by using more age-specific data and applying advanced empirical methods. METHODS: Panel data from the German Ageing Survey (DEAS) (n = 1027) is used, whereby individuals are included, that participated at least in two waves. First, a blockwise fixed effects logistic regression model is carried out, which allows to investigate mediation as well as moderation effects and controls for time invariant unobserved heterogeneity. Additionally, two recursive bivariate probit models are conducted to identify further indirect pathways. FINDINGS: A mediating and moderating effect of perception of aging regarding self-rated health is found in the fixed effects model. Indirect pathways of perception of aging and retirement over sport activity (mediator) are confirmed in the recursive bivariate probit models. CONCLUSION: The results highlight the complexity of the underlying mechanisms as well as the importance of individual and needs-based designed health promotion. Here, public health policy should not solely focus on sport activity, rather it should include target group specific strategies to shape individual perceptions of aging towards a more positive view on aging, while considering the heterogeneity of middle and older age groups.
