Cost-effectiveness of school, early child care and afterschool based nutrition policies and programs to prevent obesity
Methods:The CHildhood Obesity Intervention Cost-Effectiveness Study (CHOICES) systematic review process and microsimulation model were used to estimate the impact and cost effectiveness of three nutrition policies targeting improved food and beverage offerings to children and reduced screen time. Healthcare costs averted and the cost-effectiveness of ten-year reductions in body mass index (BMI), childhood obesity prevalence and gains in quality-adjusted life years (QALYs) were estimated for the 2015 U.S. population.
Results: Costs of implementing these policies or programs in the first year range between $3.2 and $16 million with an estimated potential reach of between 370,000 and 13.3 million children aged 3-18 years. These interventions are estimated to reduce BMI by 0.023 – 0.243 unit per person on average. Over a ten-year period, these interventions are estimated to cost $15 to $627 per BMI unit reduced. Resulting healthcare cost reductions and cost-effectiveness to reduce childhood obesity and increase QALYs will be presented.
Conclusions: Cost-effectiveness analysis of interventions can assist in comparing the estimated impact of various policy and program options on short-term outcomes, costs and populations impacted. These interventions may reduce BMI at lower cost than recognized clinical interventions and have potential large population reach.
