Health behavior of working-aged Finns predicts self-reported life satisfaction in a population-based 9-years follow-up

Abstract

Background: Previous studies have shown positive association between health behavior and life satisfaction, but the studies have mostly been cross-sectional, had follow-up times up to 5 years or focused on only one health behavior domain. The aim of the study was to explore how principal health behavior domains predict life satisfaction as a composite score in a previously unexplored longitudinal setting.
