Outcome Measures

Primary Outcomes (1)

• Change in global health status outcomes (metabolic, psychological and nutritional variables, physical activity habits) from baseline to the end of the intervention, and at 6 and 12 months post-intervention.

  Plasma LDL-cholesterol concentrations, Eating behaviors (restraint, disinhibition, and susceptibility to hunger), appetite ratings (desire to eat, hunger, fullness, and prospective food consumption), psychological variables (e.g. quality of life, self-esteem), physical activity habits, dietary intakes.

  At baseline and at the end of the intervention period (4 months), and at 6 months and 1 year post-intervention (10 months and 16 months, respectively).

Secondary Outcomes (1)

• Anthropometric and metabolic variables

  At baseline and at the end of the intervention period (4 months), and at 6 months and 1 year post-intervention (10 months and 16 months, respectively).

Interventions

Health-At-Every-Size (HAES) OTHER

1. HAES group: 14 weekly sessions. Focus on general well-being and positive ways of having a healthy and satisfying lifestyle. Supported by lectures, guided self-reflection, group discussions, as well as practical exercises, this intervention aims at enhancing awareness and knowledge about biological, psychological, and sociocultural aspects of body weight. 2. SS group: 14 weekly sessions. The objective is to reproduce a structural social support provided by the group itself. Each participant offers their support to each other. Each theme discussed in the HAES group is repeated in the SS group but the health professionals in charge of the group (dietitian \& psychologist) are not counselors (as in HAES group) but only facilitators. Outcome measures: For all women under study.
