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 children’s 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
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 ≤17 years old, formerly or currently affected by obesity, who had (n = 11) or had never (n = 12) 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 child’s long-term, obesity-related health outcomes and some of this optimism is unrealistic. An understanding of how comparative optimism relates to parents’ 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 “a typical child in their community” would be affected by overweight, get married, and complete a 4-year college degree by age 30, and the child’s 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 (−26.6 percentage points, 95% confidence interval [CI]: −35.6, −17.7) 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 (−2.2 percentage points, 95% CI: −8.1, 3.7). Conclusions. Some parents appear to exhibit comparative optimism around their child’s 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

The accuracy of parent-reported height and weight for 6–12 year old U.S. children
Abstract Background Previous studies have examined correlations between BMI calculated using parent-reported and directly-measured child height and weight. The objective of this study was to validate correction factors for parent-reported child measurements. Methods Concordance between parent-reported and investigator measured child height, weight, and BMI (kg/m2) among participants in the Neighborhood Impact on Kids Study (n = 616) was examined using the Lin coefficient, where a value of ±1.0 indicates perfect concordance and a value of zero denotes non-concordance. A correction model for parent-reported height, weight, and BMI based on commonly collected demographic information was developed using 75% of the sample. This model was used to estimate corrected measures for the remaining 25% of the sample and measured concordance between correct parent-reported and investigator-measured values. Accuracy of corrected values in classifying children as overweight/obese was assessed by sensitivity and specificity. Results Concordance between parent-reported and measured height, weight and BMI was low (0.007, − 0.039, and − 0.005 respectively). Concordance in the corrected test samples improved to 0.752 for height, 0.616 for weight, and 0.227 for BMI. Sensitivity of corrected parent-reported measures for predicting overweight and obesity among children in the test sample decreased from 42.8 to 25.6% while specificity improved from 79.5 to 88.6%. Conclusions Correction factors improved concordance for height and weight but did not improve the sensitivity of parent-reported measures for measuring child overweight and obesity. Future research should be conducted using larger and more nationally-representative samples that allow researchers to fully explore demographic variance in correction coefficients
Preferences and experiences of pediatricians on implementing national guidelines on universal routine screening of adolescents for major depressive disorder: A qualitative study
Background: To explore the preferences of pediatricians for key factors around the implementation of universal routine screening guidelines for major depressive disorder in adolescent patients in a primary care setting. Method: Semi-structured qualitative interviews were conducted with U.S. pediatricians. Participants were recruited by convenience sampling and snowball sampling. Qualitive data were summarized using thematic analysis to identify themes relevant to preferences around implementing screening strategies for adolescent patients. Recruitment ended upon reaching thematic saturation when no new themes were revealed. Results: Of the 14 participants, 11 identified as female, 3 male, 10 white, and 4 Asian. Top themes among pediatrician participants were around the screening modality (14/14 participants), screening validity (14/14), time barriers (14/14), and confidentiality barriers (12/14). Less frequently mentioned themes by pediatricians were workplace coordination and logistics (7/14), alternative starting ages for screening (7/14), more frequent screenings than annual screenings (3/14), and additional clinical training regarding depression diagnosis and treatment (2/14). Limitations: Pool of interviewed participants was limited by diversity in terms of geography, race/ethnicity, or practice settings. Conclusions: To promote the uptake of universal routine screening of adolescent major depression, pediatricians expressed it was important to address key implementation factors regarding the screening modality, screening validity, time constraints, and confidential care concerns in a primary care delivery context. Findings could be used to inform the development of implementation strategies to facilitate depression screening in primary care. Future research is needed to quantitively assess decisions and tradeoffs that pediatricians make when implementing universal screening to support adolescent mental health
