Introduction: The aim of the present study was to assess the relation between these life-style factors and suboptimal self-reported health.
Methods: A cross-sectional study was carried out on a random sample of 12,040 men and women from Copenhagen, who had answered a questionnaire regarding smoking, alcohol intake, physical activity, socio-economic status, social network, and self-perceived health.
Results: Smoking, high alcohol intake, and physical inactivity are strongly associated with a suboptimal self-reported health.
Discussion: The assumption of a correlation between a high quality of life and a shorter life cannot be confirmed by this study.
