Background: The HEROES (Healthy, Energetic, Ready, Outstanding, Enthusiastic Schools) Initiative is a school-based childhood obesity prevention program to help schools in Southern Indiana and Illinois change their culture by implementing the U.S. Centers for Disease Control and Prevention's (CDC's) Coordinated School Health Model (CSHM).
Purpose: To examine predictors for persistent overweight/obesity, deteriorated weight (e.g., normal to overweight), and improved weight (e.g., overweight to normal) status among students (N = 5309, 11 schools) who participated in the HEROES Initiative from Fall 2009 to Spring 2011.
Significance: This study illustrates the characteristics of students who are responsive or nonresponsive to the CSHM-based obesity intervention program. Method: Weight and height of students were measured at baseline, 6 months, 12 months, and 18 months. CDC growth chart was used to group students into different weight categories. Then, students were further grouped into persistent overweight/obesity, deteriorated weight, or improved weight category. SAS 9.2 was employed to examine predictors for each of these three categories using logistic regression, accounting for clustering effects within the same school and correlated repeated measures.
Results: Drinking more soda, more screen time, lower socio-economic status (SES), and attending urban schools increased the odds of belonging to persistent overweight/obesity (30.6%) and deteriorated weight (6.9%) categories compared to persistent non-overweight group. SES at both school-level and individual-level and engaging in team sports significantly predicted weight improvement of students (6.2%).
Conclusion: While SES is an important determinant of weight category change, students' screen time, soda consumption, and team sports participation are also important determinants.
