Associations of physical activity with depressiveness and coping in subjects with high-grade obesity aiming at bariatric surgery: a cross-sectional study

摘要

Background Reduced physical activity is supposed to be associated with depressiveness and more passive coping patterns. For further evaluation of this assumed relation we studied energy expenditure due to physical activity - usually referred to as activity thermogenesis (AT) - together with depressiveness (clinical diagnosis, depression module of the Patient Health Questionnaire), and coping behaviours (Brief COPE Inventory) in 50 patients with high-grade obesity (42?±?12?years; 9 with II° and 41 with III° obesity) aiming at bariatric surgery. Methods AT was assessed with a portable armband device (SenseWear? armband). Depressiveness and coping were assessed using validated questionnaires. Results Weight-adjusted non-exercise AT and intensity of physical activity (metabolic equivalent) correlated inversely with body mass index (non-exercise AT: r?=??0.32, P?r?=??0.37, P?r?=??0.34, P?r?=??0.36, P?r?=??0.36, P?r?=??0.38, P?r?=??0.38, P?r?=??0.40, P?r?=??0.36, P?r?=??0.38, P? Conclusions AT was not associated with depressiveness. Furthermore, supposed adaptive coping strategies of individuals aiming at bariatric surgery were negatively associated with AT.
