ABSTRACT
OBJECTIVE:
To estimate lifetime cost effectiveness of lifestyle interventions to treat overweight and obese children, from the UK National Health Service perspective.DESIGN:
An adaptation of the National Heart Forum economic model to predict lifetime health service costs and outcomes of lifestyle interventions on obesity-related diseases.SETTING:
Hospital or community-based weight-management programmes. POPULATION Hypothetical cohorts of overweight or obese children based on body mass data from the National Child Measurement Programme.INTERVENTIONS:
Lifestyle interventions that have been compared with no or minimal intervention in randomized controlled trials (RCTs). MAIN OUTCOMEMEASURES:
Reduction in body mass index (BMI) standard deviation score (SDS), intervention resources/costs, lifetime treatment costs, obesity-related diseases and cost per life year gained.RESULTS:
Ten RCTs were identified by our search strategy. The median effect of interventions versus control from these 10 RCTs was a difference in BMI SDS of -0.13 at 12 months, but the range in effects among interventions was broad (0.04 to -0.60). Indicative costs per child of these interventions ranged from £108 to £662. For obese children aged 10-11 years, an intervention that resulted in a median reduction in BMI SDS at 12 months at a moderate cost of £400 increased life expectancy by 0.19 years and intervention costs were offset by subsequent undiscounted savings in treatment costs (net saving of £110 per child), though this saving did not emerge until the sixth or seventh decade of life. The discounted cost per life year gained was £13 589. Results were broadly similar for interventions aimed at children aged 4-5 years and which targeted both obese and overweight children. For more costly interventions, savings were less likely.CONCLUSION:
Interventions to treat childhood obesity are potentially cost effective although cost savings and health benefits may not appear until the sixth or seventh decade of life.
