Camp-based family treatment of childhood obesity: randomised controlled trial.

Abstract

To compare the effectiveness of a 2-year camp-based family treatment programme and an outpatient programme on obesity in two generations. Pragmatic randomised controlled trial. Rehabilitation clinic, tertiary care hospital and primary care. Families with at least one child (7-12 years) and one parent with obesity. Summer camp for 2 weeks and 4 repetition weekends or lifestyle school including 4 days family education<i>.</i> Behavioural techniques motivating participants to healthier lifestyle. Children: 2-year changes in body mass index (BMI) SD score (SDS). Parents: 2-year change in BMI. Main analyses: linear mixed models. Ninety children (50% girls) were included. Baseline mean (SD) age was 9.7 (1.2) years, BMI 28.7 (3.9) kg/m² and BMI SDS 3.46 (0.75). The summer-camp children had a lower adjusted estimated mean (95% CI) increase in BMI (-0.8 (-3.5 to -0.2) kg/m²), but the BMI SDS reductions did not differ significantly (-0.11 (-0.49 to 0.05)). The 2-year baseline adjusted BMI and BMI SDS did not differ significantly between summer-camp and lifestyle-school completers, BMI 29.8 (29.1 to 30.6) vs 30.7 (29.8 to 31.6) kg/m² and BMI SDS 2.96 (2.85 to 3.08) vs 3.11 (2.97 to 3.24), respectively. The summer-camp parents had a small reduction in BMI (-0.9 (-1.8 to -0.03) vs -0.8 (-2.1 to 0.4) in the lifestyle-school group), but the within-group changes did not differ significantly (0.3 (-1.7 to 2.2)). A 2-year family camp-based obesity treatment programme had no significant effect on BMI SDS in children with severe obesity compared with an outpatient family-based treatment programme. NCT01110096.
