Effectiveness of a publicly funded clinical paediatric weight management program on obesity outcomes.

Objective: To determine the effectiveness of a publicly funded, paediatric weight management clinic in decreasing obesity.

Methods: A retrospective chart review of patients four to 16 years of age, from 2006 to 2009, was performed at a medically supervised weight management clinic (n=121). Patients participated in monthly visits and were educated about the cognitive behavioural and nutritional aspects of weight management.

Results: The sample included 51 male and 70 female patients with a mean (± SD) initial age of 11.7±3.0 years. Patients participated in 6.4±6.5 visits (range one to 31 visits) over 13.7±15.5 months and 7.4% of patients discontinued treatment after their initial visit. Of the patients who attended the clinic >1 time, 66.1% attended for at least four months, 48.2% attended for >8 months and 33.0% attended for >1 year. Over the course of their treatment, patients experienced a weight gain of 3.8±9.5 kg, but a reduction in body mass index (BMI) percentile (-1.1±3.6%). Post-treatment, the prevalence of obesity decreased from 96.7% to 87.5%. Patients with longer treatment times (>12 months) attained significantly lower final BMI percentiles than patients with shorter treatment times; however, there was no difference in the rate of reduction. Initial treatment age, sex and medical conditions were not related to BMI percentile change.

Conclusions: This paediatric weight management program effectively reduced the prevalence of obesity. Patients who had longer treatment times experienced greater reductions in obesity. Overall, the present study highlights that long-term patient attendance may be needed to better support paediatric weight management patients.
