[Sedentary lifestyles. Classification of different target groups for the promotion of health-enhancing physical activities].

The article investigates different sub-groups of sedentary adults based on their socio-demographic characteristics and perceived barriers to physical activity. Data stem from the Germans Survey of Sedentary Adults (n=10.000) and the data analysis used logistic regressions and cluster analysis. The results indicate that sedentary adults are a diverse group when socio-demographic characteristics and perceived barriers to physical activity are considered. Barriers such as lack of social contacts or time for physical activity are perceived by specific subgroups of this population. In contrast, only few sedentary adults report multiple barriers to physical activity. The results also provide indications for potentially successful strategies to promote physical activity among sedentary adults.
