18-month outcomes of a community-based treatment for childhood obesity

Few studies have evaluated community-based interventions for childhood obesity and even fewer provide efficacy data 1 year later.

This study assessed changes in relative weight 1 year after a 6-month treatment for childhood obesity.

Participants were 155 overweight/obese children/adolescents and their caregivers. The primary outcome was change in child percent over body mass index (BMI) from 6 to 18 months. The primary outcome was also assessed from 0 to 18 months and changes in secondary outcomes (BMI z-score, guardian weight, health-related quality of life [HRQoL]) were examined from 6-18 to 0-18 months.

From 6 to 18 months, there were no significant changes in any outcome. From 0 to 18 months, there were improvements in BMI z-score (P < 0.001), HRQoL (P < 0.001) and guardian weight (P = 0.02).

Changes in relative weight and HRQoL observed after 6 months persisted 1 year later. The programme produced reductions in BMI z-score and obesity prevalence but not in percent over BMI from 0 to 18 months.
