Adolescent sources of stress, stress levels, and associations between stress and changes in weight outcomes at the time of COVID-19 related school closure in March 2020.

Objective: Stress is associated with weight changes, yet how level and sources of stress relate to this association is poorly understood. This mixed methods study examined associations between adolescent stress at the COVID-19 pandemic onset and standardized BMI (BMIz) over a three-month period. Methods: Participants (N = 197, mean age 13.66 ± 1.43 years, 85% Hispanic, 56% female) were recruited from a charter school in Texas to participate in a healthy lifestyle intervention during physical education class. We calculated BMIz using height and weight measurements taken December 2019 and the week of COVID-19 school closures in March 2020. We measured stress in March 2020 with the 4-item Perceived Stress Scale. We ran a multiple linear regression model controlling for baseline BMIz (December 2019), age, sex, intervention condition, and assessed the interaction between baseline BMIz and PSS-4 score on BMIz change. Results: Overall, our sample had an average PSS-4 score of seven and mean BMIz decrease of 0.04 over the three-month period. We observed a significant interaction between PSS-4 score and baseline BMIz. At lower baseline BMIz scores, higher PSS-4 scores were associated with decreases in BMIz over time. There was no significant association at higher baseline BMIz scores. COVID-19 pandemic-related concerns and school performance were the two primary stressors reported. Conclusions: The relation between stress and weight changes differed based on starting weight status. Future interventions should consider the influence of external stressors on intervention adherence and outcomes.

Outcomes From Healthy Eating and Physical Activity Recognition Programs in Early Child Care and Education: A Scoping Review.

OBJECTIVE: Recognition programs are designed to incentivize early care and education (ECE) settings to implement childhood obesity prevention standards, yet little is known regarding their efficacy. This scoping review details characteristics, methodologies, and criteria used to evaluate recognition programs, identifies gaps in evaluation, and synthesizes existing evidence. DATA SOURCE: A public health librarian created the search strategies for six databases: Ovid MEDLINE, AGRICOLA, CAB Abstracts, PAIS Index, ERIC, and Scopus. STUDY INCLUSION AND EXCLUSION CRITERIA: Inclusion criteria include recognition program, ECE setting, nutrition or physical activity, and qualitative or quantitative outcomes. Exclusion criteria include programming without recognition component, no ECE setting, no nutrition or physical activity outcome, case studies, or not written in English. DATA EXTRACTION: Three researchers independently extracted and complied data into an Excel spreadsheet. DATA SYNTHESIS: Tables were created describing location, recognition program criteria, award incentive, study design, study sample, risk of bias, and outcomes (e.g., menu nutrition) evaluated in each study. RESULTS: Three unique recognition programs (described in 7 studies) provided technical assistance, incentives, and training. While outcome measures and study designs varied across programs, it is clear that recognition programs are well accepted and feasible, and one study demonstrated beneficial weight outcomes. CONCLUSION: Although additional evaluation is needed, recognition programs may be a promising strategy to improve obesity prevention practices in ECE.

Response to school-based interventions for overweight and obesity: A systematic scoping review.

Heterogeneity of response to paediatric obesity interventions is one of the greatest challenges to obesity care. While evaluating school-based interventions by mean changes compared to control is important, it does not provide an understanding of the individual variability in response to intervention. The objective of this study was to comprehensively review school-based interventions that reported study results in terms of response and identify definitions of response used. A scoping review was conducted using a systematic search of five scientific databases from 2009 to 2021. Inclusion criteria included randomized controlled trial design, school-based setting, weight-based outcomes (e.g., BMI, BMI z-score), weight-based outcomes analysed among youth with overweight/obesity, a study conducted in a developed country and publication in English. A total of 26 reports representing 25 unique studies were included. Overall, 19% (5/26) of articles reported response. Response was defined in three ways: maintenance/decrease in BMI z-score, decrease in BMI z-score ≥0.10, and decrease in BMI z-score ≥0.20. Few school-based interventions identified an a priori intervention goal or identified the proportion of participants who responded to the intervention. Without such evaluation participants who do not benefit are likely to be overlooked.
