The cost of a primary care-based childhood obesity prevention intervention
Background: United States pediatric guidelines recommend that childhood obesity counseling be conducted in the primary care setting. Primary care-based interventions can be effective in improving health behaviors, but also costly. The purpose of this study was to evaluate the cost of a primary care-based obesity prevention intervention targeting children between the ages of two and six years who are at elevated risk for obesity, measured against usual care. Methods: High Five for Kids was a cluster-randomized controlled clinical trial that aimed to modify childrenâs nutrition and TV viewing habits through a motivational interviewing intervention. We assessed visit-related costs from a societal perspective, including provider-incurred direct medical costs, provider-incurred equipment costs, parent time costs and parent out-of-pocket costs, in 2011 dollars for the intervention (n = 253) and usual care (n = 192) groups. We conducted a net cost analysis using both societal and health plan costing perspectives and conducted one-way sensitivity and uncertainty analyses on results. Results: The total costs for the intervention group and usual care groups in the first year of the intervention were 64,522, 12,192 (95% CI [13,174]). The mean costs for the intervention and usual care groups were 255, 63 (95% CI [69]) per child, respectively, for a incremental difference of 191, $202]) per child. Children in the intervention group attended a mean of 2.4 of a possible 4 in-person visits and received 0.45 of a possible 2 counseling phone calls. Provider-incurred costs were the primary driver of cost estimates in sensitivity analyses. Conclusions: High Five for Kids was a resource-intensive intervention. Further studies are needed to assess the cost-effectiveness of the intervention relative to other pediatric obesity interventions. Trial registration ClinicalTrials.gov Identifier: NCT00377767

Examining Methods Used to Evaluate the Cost-Effectiveness of Childhood Obesity Interventions
This dissertation examines methods used to evaluate the cost-effectiveness of childhood obesity interventions in order to help decision-makers prioritize among competing health programs using standardized outcomes. Chapter 1 generates inputs for use in cost-effectiveness analyses (CEAs) of childhood obesity interventions. In Chapter 1.1, I use data from the Medical Expenditure Panel Survey to predict expenditures associated with obesity in childhood and adolescence. I found that obese children and adolescents have significantly different expenditures than their normal weight counterparts. I conclude that exclusion of obesity-related medical expenditures can potentially undervalue the cost-effectiveness of interventions. In Chapter 1.2, I use data from the Study of Early Child Care and Youth Development to examine the longitudinal trajectory of child weight. I derived probabilities of transitioning between weight classes that can be used in a decision-analytic model to extrapolate the effectiveness of childhood obesity interventions beyond childhood. I found that deviating from CDC BMI reference categories can more accurately capture the risk of future obesity. In Chapter 2, I evaluate the cost-effectiveness of a primary care-based obesity prevention program, High Five for Kids. Over two years, High Five for Kids was low-cost, but only marginally effective in reducing BMI. I used a decision analytic simulation model to extrapolate trial outcomes over a 10-year horizon, and found that in the long-term, primary care based obesity prevention was likely to be cost-effective relative to usual care. I also found that key methodological considerations can meaningfully influence the cost-effectiveness of childhood obesity interventions. In Chapter 3, I develop an agent-based model to explore the dynamics of the potential spread of obesity within families. I found that the âcontagionâ of obesity could result in significant collateral weight loss in family members not targeted in an intervention. As a result, CEAs may underestimate the benefits of obesity interventions. Moreover, I found that unless interventions are targeted toward all obese children in a family, the contagion of obesity can hinder weight loss in intervention targets. This model can be leveraged as a tool to optimize family-based obesity intervention strategies and inform randomized controlled obesity prevention trials

Replication Data for: Are Mechanical Turk worker samples representative of health status and health behaviors in the U.S.?
A cross-sectional survey comprised of questions from the nationally-representative 2014 Behavioral Risk Factor Surveillance System (BRFSS) and 2014 National Health and Nutrition Examination Survey (NHANES) was administered to 591 MTurk workers and 393 masters in 2016. Health status (asthma, depression, BMI, and general health), health behaviors (influenza vaccination, health insurance, smoking, and physical activity), and demographic characteristics of the two MTurk populations (workers and masters) were compared to each other and, using Poisson regression, to a nationally-representative BRFSS and NHANES samples
Exploring parent attitudes around using incentives to promote engagement in family-based weight management programs
Incentives can promote adult wellness. We sought to examine whether incentives might help overcome barriers to engagement in child weight management programs and the ideal value, type and recipient of incentives. In 2017, we conducted semi-structured phone interviews with parents of children â€17âŻyears old, formerly or currently affected by obesity, who had (nâŻ=âŻ11) or had never (nâŻ=âŻ12) participated in family-based behavioral treatment (FBT) for obesity. Interviews explored the range and type of incentives families would be willing to accept. Interview transcripts were coded and data were analyzed using a thematic analysis. We found that some parents were skeptical about receiving cash incentives. However, once treatment-related costs were identified, some became more interested in reimbursement for out of pocket expenditures. Most parents felt up to 50/month, but there was concern about incentives affecting a child's intrinsic motivation for behavior change. All parents acknowledged that moderate incentives alone couldn't overcome the realities of structural and familial barriers to engaging in weight management programs. In summary, we identified aspects of an incentive program to promote engagement in FBT that would be desirable and feasible to implement. Future quantitative work can reveal the value and structure of incentives that are effective for improving obesogenic health behaviors and outcomes.

Are Mechanical Turk worker samples representative of health status and health behaviors in the U.S.?
INTRODUCTION:Amazon's Mechanical Turk (MTurk) is frequently used to administer health-related surveys and experiments at a low cost, but little is known about its representativeness with regards to health status and behaviors. METHODS:A cross-sectional survey comprised of questions from the nationally-representative 2014 Behavioral Risk Factor Surveillance System (BRFSS) and 2014 National Health and Nutrition Examination Survey (NHANES) was administered to 591 MTurk workers and 393 masters in 2016. Health status (asthma, depression, BMI, and general health), health behaviors (influenza vaccination, health insurance, smoking, and physical activity), and demographic characteristics of the two MTurk populations (workers and masters) were compared to each other and, using Poisson regression, to a nationally-representative BRFSS and NHANES samples. RESULTS:Workers and master demographics were similar. MTurk users were more likely to be aged under 50 years compared to the national sample (86% vs. 55%) and more likely to complete a college degree than the national sample (50% vs. 26%). Adjusting for covariates, MTurk users were less likely to be vaccinated for influenza, to smoke, to have asthma, to self-report being in excellent or very good health, to exercise, and have health insurance but over twice as likely to screen positive for depression relative to a national sample. Results were fairly consistent among different age groups. CONCLUSIONS:MTurk workers are not a generalizable population with regards to health status and behaviors; deviations did not follow a trend. Appropriate health-related uses for MTurk and ways to improve upon the generalizability of MTurk health studies are proposed
Healthy, Wealthy, and Wise? Exploring Parent Comparative Optimism About Future Child Outcomes
Objectives. Comparative optimism is present in parental predictions of their childâs long-term, obesity-related health outcomes and some of this optimism is unrealistic. An understanding of how comparative optimism relates to parentsâ predictions of health versus other child outcomes could contribute to the development of interventions and strategies pediatricians can use to improve risk assessment. Methods. In a nationally representative survey, we asked American parents of 6- to 17-year-old children ( n = 410) to estimate the chances that their child and âa typical child in their communityâ would be affected by overweight, get married, and complete a 4-year college degree by age 30, and the childâs future salary at age 30. We collected data on family demographic and health characteristics. We modeled the difference in parent predictions for their child versus the typical child using multivariate linear regressions. Results. Compared to the typical child, parents were less likely to predict that their child would be affected by overweight (â26.6 percentage points, 95% confidence interval [CI]: â35.6, â17.7) and more likely to predict that their child would complete a 4-year degree (16.7 percentage points, 95% CI: 2.5, 31.0). Parents predicted their child would have a higher income than the typical child at age 30 (7,487, $23,046). Parents did not predict that their child would be more likely than the typical child to be married by age 30 (â2.2 percentage points, 95% CI: â8.1, 3.7). Conclusions. Some parents appear to exhibit comparative optimism around their childâs future weight status, education, and economic outcomes, but not marriage. Future experimental work should assess whether risk communication approaches that consider optimism bias influence parent risk perception and parenting behaviors
