Objective: Healthy dietary habits, physical activity, and positive mental health help prevent or manage excess weight among adolescents. HealthyMe curriculum modules are designed to improve those health behaviors among middle and high school students. Methods: The HealthyMe curriculum was implemented through health classes and health-promoting activities. We evaluated the changes in weight and key health behaviors from 23 schools across 8 states in the 2017-2018 academic year. We analyzed pre-post comparisons adjusting for lesson attendance, race/ethnicity, and age, and for clustering effects of schools. We also compared percentages of improved behaviors between sexes and between rural and non-rural schools. Results: Data were available from 1463 students (44% boys, age = 15.6 (1.3) years). Body mass index (BMI) metrics, in general, were significantly improved among students who were overweight or obese. Significant positive health behavior changes reported by both boys and girls were increasing breakfast and decreasing sugary beverage consumption. Girls significantly increased fruit and vegetable intakes and physical activities; boys significantly decreased dinner at home and physical activities. Students in rural schools tended to have a smaller number of significant changes and improved behaviors. Conclusions: The HealthyMe curriculum improved weight among students, who were overweight or obese, even though it focuses on health behaviors rather than directly addressing weight issues. The positive health behavior changes in conjunction with weight improvements may reflect synergy between the health promotion teaching and school policies.

BACKGROUND: School health curricula should help students choose health goals related to the Dietary Guidelines (DG) recommendations addressing obesity. We aimed to identify characteristics associated with choice of DG recommendation items. METHODS: In 12 HealthCorps affiliated high schools, students completed a 19-item web-based questionnaire that provided a personalized health-behavior feedback report to guide setting SMART (Specific, Measurable, Action-oriented, Realistic, Time-bound) goals. We examined if gender, weight-status, and personalized feedback report messages were related to student-selected SMART Goals. RESULTS: The most frequent SMART Goals focused on breakfast (22.4%), physical activity (21.1%), and sugary beverages (20.4%). Students were more likely to choose a SMART goal related to breakfast, sugary beverages, fruit/vegetable intake or physical activity if their feedback report suggested that health behavior was problematic (p
