A family-based healthy lifestyle intervention effectively reduced substance use, including alcohol, marijuana, and non-prescription drugs, in overweight Hispanic adolescents over 24 months. The intervention did not significantly impact sexual risk behaviors.
Area of Science:
- Public Health
- Adolescent Health
- Behavioral Science
Background:
- Overweight and obesity are prevalent among Hispanic adolescents.
- Substance use and sexual risk behaviors are significant public health concerns in this demographic.
- Family-based interventions show promise in addressing multiple health behaviors.
Purpose of the Study:
- To evaluate the efficacy of a family-based healthy lifestyle intervention.
- To reduce substance use and sexual risk behaviors in overweight/obese Hispanic adolescents.
- To compare the intervention group with a control group receiving prevention as usual over 24 months.
Main Methods:
- Randomized controlled trial with 280 overweight/obese Hispanic adolescents (7th/8th grade) and their caregivers.
- Intervention group received a healthy lifestyle family-based program.
- Control group received standard community services for overweight/obese youth.
Main Results:
- Significant reductions in adolescent alcohol use (b = -0.37).
- Significant reductions in adolescent marijuana use (b = -1.00).
- Significant reductions in adolescent non-prescription drug use (b = -3.77).
- No significant intervention effects on adolescent sexual risk behaviors.
Conclusions:
- The Familias Unidas for Health and Wellness intervention effectively reduces alcohol, marijuana, and non-prescription drug use in Hispanic adolescents.
- Family-based healthy lifestyle interventions can be a viable strategy for substance use prevention.
- Further research is needed to address sexual risk behaviors in this population.
