Abstract
OBJECTIVE: To report 12-month outcomes from a multidisciplinary child obesity intervention program, targeting high-risk groups. METHODS: In this unblinded randomized controlled trial, participants (recruited January 2012-August 2014) were aged 5 to 16 years, resided in Taranaki, Aotearoa/New Zealand, and had BMI ≥ 98th percentile or BMI >; 91st percentile with weight-related comorbidities. Randomization was by minimization (age and ethnicity), with participants assigned to an intense intervention group (home-based assessments at 6-month intervals and a 12-month multidisciplinary program with weekly group sessions) or to a minimal-intensity control group with home-based assessments and advice at each 6-month follow-up. The primary outcome was the change in BMI standard deviation score (SDS) at 12 months from baseline. A mixed model analysis was undertaken, incorporating all 6- and 12-month data. RESULTS:Two hundred and three children were randomly assigned (47% Māori, 43% New Zealand European, 53% female, 28% from the most deprived quintile, mean age 10.7 years, mean BMI SDS 3.12). Both groups displayed a change in BMI SDS at 12 months from baseline (-0.12 control, -0.10 intervention), improvements in cardiovascular fitness (P < 0.0001), and improvements in quality of life (P < 0.001). Achieving ≥ 70% attendance in the intense intervention group resulted in a change in BMI SDS of -0.22. CONCLUSIONS: This program achieved a high recruitment of target groups and a high rate of BMI SDS reduction, irrespective of intervention intensity. If retention is optimized, the intensive program doubles its effect.
