ABSTRACT

BACKGROUND: A 6-month pediatric weight loss program showed modest success, but the sustainability of this success after 12 months was unclear. The present study aims tomeasure the medium-term effectiveness of family-based weight management in pediatric primary care to reduce body weight in children living with obesity. METHODS: In a retrospective cohort study, children ages 3 to 17 years with obesity in Kaiser Permanente Orange County, California, who enrolled in a weight management program between April 2014 and December 2018 (FB-WMG, n = 341) were compared to children referred but not enrolled (Ref-CG, n = 317) and controls matched by sex, age, zip code and BMI (Area-CG, n = 801). The relative distance from the median BMI-for-age at months 0, 6, and 12 were expressed as difference-in-differences (DID) using multivariable linear regressions with robust standard error. RESULTS: The baseline BMI-for-age was 98.6 (SD 1.08) percentile in FB-WMG, 98.2 (SD 1.22) percentile in Ref-CG, and 98.6 (1.13 in Area-CG). FB-WMG had a median of 3 visits (P25 1 visit, P75 5 visits) in the first 6 months. Despite a more considerable decrease in the relative distance to the median BMI-for-age in FB-WMG children with 3+ visits after 6 months, the success obtained was not sustained at 12 months (DID FB-WMG vs Area-CG -0.34, 95% CI - 3.00 to 2.33%, FB-WMG vs Ref-CG -0.39, 95% CI - 3.14 to 2.35%). At 12 months, there was no statistical significant difference between the three groups (FB-WWG, Ref-CG, Area-CG). CONCLUSIONS: The initial success in weight management was not sustained in the absence of continued support for healthy lifestyle changes. Based on current evidence, continued support is necessary to maintain and promote success beyond a brief 6 month intervention. Long-term pediatric weight management programs are needed to promote continuing progress.

ABSTRACT

INTRODUCTION: The evidence supporting the effectiveness of weight loss interventions with low to medium intensity is limited. OBJECTIVE: To measure the effectiveness of a family-based weight management intervention in pediatric primary care to reduce body weight in children. METHODS: Electronic medical record data of pediatric patients in Kaiser Permanente Orange County, California, who were enrolled in weight management between April 2014 and December 2018 (family-based behavior-changing weight management [FB-WMG], n = 162) and compared with a control group (CG) of patients who were referred but did not enroll (Ref-CG, n = 203) and an area-matched CG also matched by sex, age, zip code, and body mass index (BMI) (Area-CG, n = 287). BMI was measured at the first visit (or index date) and after 6 months. RESULTS: Children enrolled in the FB-WMG had 5 (interquartile range = 3-6) sessions over the first 6 months of the program. Most FB-WMG patients (69.1%) reduced or maintained BMI over 6 months, compared with 45.8% of Ref-CG (p < 0.001) and 57.8% of Area-CG (p = 0.02). In girls 3 to 12 years of age, 75% of participants reduced or maintained BMI, compared with 42% of Ref-CG (p < 0.001) and 59.8% of Area-CG (p = 0.07). On average, the difference in BMI change over the 6-month follow-up period was -0.85 kg/m² (95% confidence interval = -1.25 to -0.46 kg/m²) compared with Ref-CG and -0.28 kg/m² (95% confidence interval = -0.63 to 0.08 kg/m²) and Area-CG. CONCLUSION: Low- to moderate-intensity family-based weight management intervention in primary care can be successful after only 6 months compared with a referred control group.
