Activité physique, transport actif et sédentarité : facteurs individuels associés et conséquences sur la santé chez les adultes français

Abstract : Physical activity is a protective factor for common chronic diseases, while sedentary behavioris a risk factor. Among the different domains of habitual physical activity, active transportation (walking, cycling) is a topic of growing interest. A better understanding of the determinants and health effects of physical activity and sedentary lifestyles is essential to develop public health interventions targeted for at-risk populations. The objectives of this thesis were to investigate some individual factors associated with specific domains of walking and cycling, and to explore the relationship of specific areas of sedentary lifestyle with health outcomes, taking into account the effects of habitual physical activity. We measured physical activity and sedentary behavior cross-sectionally with questionnaire in the NutriNet-Santé French adults cohort (n = 39,295 subjects) and longitudinally in the SU.VI.MAX cohort (n =2,841). Our results indicate that the different domains of walking (commuting, leisure andutility) and their relationships with individual factors are not homogeneous, that during the transition to retirement the decrease in occupational physical activity was not offset by newly developed behaviors, and finally that specific physical activity and sedentary lifestyles could affect cardiometabolic risk factors and excessive daytime sleepiness. These results should contribute to a better understanding of the health behaviors of the French population, in order to better target preventive and health promotion interventions.
