Guided Self-Help vs Group Treatment for Children With Obesity: A Randomized Clinical Trial.

BACKGROUND AND OBJECTIVES

Family-based behavioral treatment (FBT) for children with obesity is provided in weekly parent and child groups over 6 months. A guided self-help FBT program (gshFBT) is provided to the dyad in short meetings. Both interventions provide the same content; however, gshFBT provides this content in less time (FBT = 23 hours, gshFBT = 5.3 hours). This study aimed to evaluate whether gshFBT is noninferior to FBT on child weight loss and cost-effectiveness.

METHODS

150 children aged between 7.0 and 12.9 years with a BMI between the 85th and 99.9th percentile and their parent were recruited and randomized to a 6-month program of gshFBT (n = 75) or FBT (n = 75) and were followed 12 months post-treatment.

RESULTS

A total of 150 children (mean age = 10.1 years, 49% female, mean BMIz = 2.09) and their parent (mean age = 41.5 years, 87% female, 45% Hispanic, 37% White non-Hispanic, 9.7% Asian, 4.8% Black, 7.3% other) were recruited from the San Diego Metropolitan area. Joint LME models showed that gshFBT was noninferior to FBT on child weight loss (ΔBMIz = -0.02 [90% credible interval [CI] -0.08-0.05, P = .65]; ΔBMIp95% = -1.57 [90% CI -4.46-1.31, P = .28]) and cost less (cost/dyad gshFBT = $1498; FBT = $2775).

CONCLUSION

The gshFBT program provided similar weight losses for children with less contact hours and with lower cost than FBT. The reduced time and ease of scheduling for the family in gshFBT will allow for an increased reach of treatment to a greater proportion of families in need.
