Evaluating dose delivered of a behavioral intervention for childhood obesity prevention: a secondary analysis.

ABSTRACT: BACKGROUND:Current recommendations for intensive behavioral interventions for childhood obesity treatment do not account for variable participant attendance, optimal duration of the intervention, mode of delivery (phone vs. face-to-face), or address obesity prevention among young children. A secondary analysis of an active one-year behavioral intervention for childhood obesity prevention was conducted to test how "dose delivered" was associated with body mass index z-score (BMI-Z) across 3?years of follow-up. METHODS:Parent-child pairs were eligible if they qualified for government assistance and spoke English or Spanish. Children were between three and 5 years old and were at risk for but not yet obese (BMI percentiles ?50th and??6) and maintenance calls (>?8) were predicted to have lower BMI-Z. Sustained impacts were not statistically significant at 2- or 3-year follow-up. CONCLUSIONS:In a behavioral intervention for childhood obesity prevention, the combination of a modest dose of face-to-face sessions (>?6?h over 3?months) with sustained maintenance calls (>?8 calls over 9?months) was associated with improved BMI-Z at 1-year for underserved preschool aged children, but sustained impacts were not statistically significant at 2 or 3?year follow-up. CLINICAL TRIAL REGISTRATION:The trial was registered on ClinicalTrials.gov (NCT01316653) on March 16, 2011, which was prior to participant enrollment.
