Summary
Predictors of dropout in the "Mexa-se" intervention varied by body mass index (BMI) category. Increased age was a factor for adequate BMI, while age, socioeconomic status, and afternoon study predicted dropout in overweight students.
Area of Science:
- Public Health
- Pediatrics
- Behavioral Science
Background:
- Childhood obesity is a growing concern, necessitating effective interventions.
- Understanding dropout predictors is crucial for optimizing intervention effectiveness.
- The 'Mexa-se' intervention aimed to improve physical activity and health behaviors in students.
Purpose of the Study:
- To identify predictors of dropout in the 'Mexa-se' intervention.
- To analyze these predictors based on body mass index (BMI) categories.
- To inform future intervention strategies for student retention.
Main Methods:
- Controlled, non-randomized study design.
- Intervention included increased physical activity (PA) in physical education (PE), active recess, and educational sessions.
- Binary logistic regression analysis was used to identify independent predictors.
Main Results:
- The overall dropout rate was 26.8%.
- For students with adequate BMI, increased age predicted dropout.
- For overweight students, increased age, socioeconomic status, and afternoon study period predicted dropout.
Conclusions:
- Socio-demographic factors significantly predict dropout from the 'Mexa-se' intervention.
- Dropout predictors differ across BMI categories, highlighting the need for tailored approaches.
- Intervention strategies should consider individual student characteristics for improved engagement.
