How are body mass and body attitude impacted by a behaviour change intervention in primary care? A pragmatic randomised controlled trial.

This study evaluated the effect of behaviour change interventions at Norwegian Healthy Life Centres on change in body mass index (BMI) and body attitude, and explored the predictors for change after 6 months. We randomised 118 participants to either an intervention or a control group. Eligible participants: ⩾18 years and able to take part in group-based interventions.
