The objective is to examine the prevalence and health-care costs associated with asthma, epilepsy, hypertension, food allergies, and diabetes in children aged 0–18 years. Prevalence was calculated using 2005–2012 Medical Expenditure Panel Survey (MEPS) data, a population-based, nationally representative sample. Using MEPS, two-part models estimated the cost of each condition for all children while controlling for sociodemographic categories. Prevalence rates varied by race and ethnicity across conditions. Females had higher prevalence of all chronic conditions, except epilepsy. An additional US$1,377.60–US$9,059.49 annually were spent on medical expenses for children aged 0–18 years, with asthma, diabetes, or epilepsy compared to children without these conditions. This is the first study to examine the costs and prevalence of chronic health conditions in children and adolescents using a single data set. Understanding the odds of having a condition by sociodemographic categories highlights disparities that can potentially inform school nurses on the best allocation of resources to serve students.
Community-based interventions may reduce and prevent childhood obesity by transforming the environments in which children live, learn, and play through a series of interventions implemented throughout the community that encourage healthy behaviors. While empirical support is building for the effectiveness of such interventions, little is known about the economic costs and benefits of community-wide childhood obesity interventions. This study examined whether the benefits of a community-wide, child-focused, obesity prevention intervention, Shape Up Somerville: Eat Smart Play Hard (SUS), exceeded its costs by estimating its return on investment.
The SUS intervention study occurred in Somerville, Massachusetts (and in two additional geographic areas, which were the study's control group) during the 2003/04 and 2004/05 school years. We estimated SUS's costs using SUS data over the two-year intervention. We estimated benefits (i.e., healthcare costs and productivity losses averted for children and their parents) over a ten-year time horizon using SUS effectiveness results and other sources. SUS generated an estimated $1.51 in savings for every $1.00 invested in the program (return on investment of $0.51). Over ten years, the estimated costs averted were over $500,000 with net benefits of $197,120 (2014 dollars).
SUS was estimated to be a cost-saving intervention when examined over a ten-year time horizon. The excess benefits generated by SUS likely arose from the community-wide nature of the intervention which extended exposure (and estimated benefits) beyond children to parents as well. These results illustrate that allocating resources to community-wide, child-focused obesity prevention interventions may be a beneficial investment.
The benefits of a community-based environmental change childhood obesity intervention can spill over to parents, resulting in decreased parental BMI. Further research is warranted to examine the effects of this type of intervention on parental health behaviors and health outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
