Brief Summary:
The primary objectives of this randomized clinical trial are a to implement and test the impact of a 1-year lifestyle obesity treatment program based on Self-Determination Theory on 3-year change in physical activity and motivation for exercisephysical activity body weight and fat and selected eating variables b to identify behavioral and psychosocial theory-based moderators or mediators of primary outcomes especially physical activity and body weight
Detailed Description:
Obesity and sedentary lifestyles are worldwide threats to public health but feasible and effective strategies to tackle these problems are scarce The identification of variables that explain why only a sub-group of overweight persons succeeds at increasing physical activity and achieving long-term weight control is a key research topic in exercise and sports sciences Subjects are 260 healthy women BMI 25 to 40 kgm2 aged between 25 and 50 years premenopausal of whom half receive the treatment intervention the remaining being randomly assigned to a control group at baseline This RCT consists of a 1-year intervention plus a 2-year no contact follow-up period The intervention group attended 30 weekly group sessions designed to follow SDT basic tenets covering PA eatingnutrition body image and other cognitive and behavioral contents Central to the intervention model are autonomy intrinsic motivation and self-regulation of behavior change Autonomy-supportive treatment climate and internal causality orientations are predicted to enhance autonomous regulation perceived competence and intrinsic motivation for the targeted behaviors resulting in lasting behavioral and body weight changes The intervention was designed to follow SDT with an emphasis on promoting intrinsic self-regulated motivation for exercise and weight control The control group received a general health education curriculum based on several 3- to 6-week long educational topics eg food safety stress management self-care body image and others Results are expected to contribute to a better understanding of how individual characteristics particularly those related to physical activity and exercise influence success better screeningreadiness testing procedures improved matching of interventions to participants and lower rates of attrition and unsuccessful weight loss attempts
