Physical inactivity, sedentary lifestyle and obesity in the European Union

Independent associations of leisure-time physical activity (inverse) and amount of time spent sitting down (direct) with BMI were found, consistent with the view that a reduction in energy expenditure during leisure time may be the main determinant of the current epidemic of obesity.

Abstract

Obesity and higher body weight are strongly associated with a sedentary lifestyle and lack of physical activity in the adult population of the European Union. These results, however, need to be interpreted with caution due to the cross-sectional design. Nonetheless, they are consistent with the view that a reduction in energy expenditure during leisure time may be the main determinant of the current epidemic of obesity.
