PURPOSE: To report the outcomes of a Health at Every Size (HAES) intervention in a real-world setting. DESIGN: Quasi-experimental design evaluating eating behaviors and psychological factors. SETTING: The HAES intervention is offered in Health and Social Services Centers in Québec (Canada). PARTICIPANTS: ) from a comparison group. INTERVENTION: The HAES intervention is composed of 14 weekly meetings provided by health professionals. It focuses on healthy lifestyle, self-acceptance, and intuitive eating. MEASURES: Eating behaviors (ie, flexible restraint, rigid restraint, disinhibition, susceptibility to hunger, intuitive eating, and obsessive-compulsive eating) and psychological correlates (ie, body esteem, self-esteem, and depression) were assessed using validated questionnaires at baseline, postintervention, and 1-year follow-up. ANALYSIS: Group, time, and interaction effects analyzed with mixed models. RESULTS: Significant group by time interactions were found for flexible restraint ( P = .0400), disinhibition ( P < .0001), susceptibility to hunger ( P < .0001), intuitive eating ( P < .0001), obsessive-compulsive eating ( P < .0001), body-esteem ( P < .0001), depression ( P = .0057), and self-esteem ( P < .0001), where women in the HAES group showed greater improvements than women in the comparison group at short and/or long term. CONCLUSION: The evaluation of this HAES intervention in a real-life context showed its effectiveness in improving eating-, weight-, and psychological-related variables among women struggling with weight and body image.
