Examine efficacy of U.S. primary care pediatric obesity treatment recommendations, within two randomized trials.
Between November 2005 - September 2007, 182 families (children aged 4–9 years, body mass index (BMI) ≥ 85th percentile) were recruited for two separate trials and randomized within trial to a 6-month intervention. Each trial had one intervention that increased child growth monitoring frequency and feedback to families (GROWTH MONITORING). Each trial also had two interventions, combining GROWTH MONITORING with an 8-session, behavioral, parent-only intervention targeting two energy-balance behaviors (Trial 1: reducing snack foods and sugar sweetened beverages [DECREASE] and increasing fruits, vegetables, and low-fat dairy [INCREASE]; Trial 2: decreasing sugar sweetened beverages and increasing physical activity [TRADITIONAL] and increasing low-fat milk consumption and reducing TV watching [SUBSTITUTES]). Child ZBMI and energy intake were assessed at 0, 6, and 12 months.
In both trials, main effects of time were found for ZBMI, which decreased at 6 and 12 months (p < 0.01). In Trial 1, ZBMI reduced from 0–6 months, which was maintained from 6–12 months (ΔZBMI 0–12 months = −0.12 ± 0.22). In Trial 2, ZBMI reduced from 0–6 and from 6–12 months (ΔZBMI 0–12 months = −0.16 ± 0.31). For energy intake, main effects of time were found in both trials and intake reduced from 0–6 months (p < 0.05), with Trial 1 reducing intake from 0–12 months (p < 0.05).
All interventions improved weight status. Future research should examine effectiveness and translatability of these approaches into primary care settings.
