Subjective well-being predicts health behavior in a population-based 9-years follow-up of working-aged Finns

Abstract The cross-sectional association between measures of subjective well-being (SWB) and various health behaviors is well-established. In this 9-year (2003–2012) follow-up study, we explored how a composite indicator of SWB (range 4–20) with four items (interest, happiness, and ease in life, as well as perceived loneliness) predicts a composite health behavior measure (range 0–4) including dietary habits, physical activity, alcohol consumption, and smoking status. Study subjects (n = 10,855) originated from a population-based random sample of working-age Finns in the Health and Social Support study (HeSSup). According to linear regression analysis, better SWB predicted better health behavior sum score with a β = 0.019 (p
