Youth mental health issues are a growing public health concern. Resilience has been identified as a mitigating factor for adverse mental health outcomes. Schools have shown an increasing interest in strategies to support students’ mental health. The purpose of this study was to evaluate a school-based 1:1 health coaching program designed to build resilience by teaching students coping skills and strategies to increase their self-efficacy. Single group intervention study with pre/post measures. Sixth grade students (aged 11-12 years) attending an urban middle school. Youth participated in up to 6 resiliency-focused, 1:1 health coaching sessions completed over 8 weeks and conducted during the school day. Health coaches utilized motivational interviewing techniques to set and work toward resilience-related goals focused on improving coping skills and self-efficacy with youth during the intervention (January through March 2020). The Child and Youth Resilience Measure-Revised and other mental health assessments were completed at baseline and immediately following completion of the intervention to evaluate outcomes. Paired sample t-tests and Hedges’ g effect sizes were conducted to evaluate intervention effectiveness. Student participation rates were assessed throughout the intervention. 287 youth participated in the study (87% participation rate) and participated in over 85% of health coaching sessions offered. A paired samples t-test revealed the youth resilience significantly increased from pre (M = 75.7, SD = 6.9) to post (M = 77.6, SD = 6.8) intervention (t[257] = 3.73, p < .001) and the size of the effect was medium (g = 0.29, 95% CI = 0.11, 0.46). The findings demonstrate that health coaching can be an effective strategy for improving resiliency in youth. Future studies evaluating how to effectively disseminate this intervention strategy are planned.

Objective: To examine the association of cord blood leptin with body mass index (BMI) growth velocity from birth to 12 months of age among infants exposed and not exposed to over-nutrition in utero (defined as maternal overweight/obesity or presence of gestational diabetes). Methods: 185 infants enrolled in the Exploring Perinatal Outcomes among Children study (76 exposed and 109 not exposed) had leptin and insulin measured in cord blood. Longitudinal weight and length measures in the first 12 months of life (average 4 per participant) obtained from medical records were used to compute BMI growth rates. Mixed models were used to examine associations of cord blood leptin with growth. Results: Compared with unexposed infants, those exposed had significantly higher cord blood insulin (8.64 v. 6.97 uU/ml, P<0.01) and leptin levels (8.89 v. 5.92 ng/ml, P=0.05) as well as increased birth weights (3438.04 v. 3306.89 g, P=0.04). There was an inverse relationship between cord leptin levels and BMI growth from birth to 12 months of age (P=0.005); however, exposure to over-nutrition in utero did not significantly modify this association (P=0.59). Conclusion: We provide support of a possible operational feedback mechanism by which lower cord blood leptin levels are associated with faster infant growth in the first year of life. Our data do not tend to support the hypothesis that this mechanism is altered in infants exposed to over-nutrition in utero; however our sample is too small to provide sufficient evidence. Larger epidemiological studies are needed to elucidate the mechanisms responsible for increased propensity for obesity in exposed offspring.
