Project Overview +
The increasing rate of obesity has become a
major public health concern in the United States. Recent reports indicate that
40% of African American adolescents are considered overweight or obese. Although effective lifestyle approaches for weight loss have been demonstrated
in Caucasian youth, little is known about effective weight loss interventions
in ethnic minority adolescents.
In part, this is because research has shown
that ethnic minorities attend fewer intervention sessions, have higher
attrition rates and lose less weight compared to Caucasians. Two fundamental
problems related to this lack of progress are addressed in this proposal and
include 1) the lack of appropriate content of weight loss interventions for
African American adolescents that integrate cultural issues, parenting skills,
and motivational strategies for increasing long-term change and, 2) the poor
dose of weight loss interventions because of participant fatigue, drop out and
barriers faced by underserved families.
The goal of this project is to conduct a randomized controlled efficacy trial to address the problems with past intervention studies by 1) making the face-to-face group intervention shorter, 2) using an on-line program to compliment the group-based intervention for increasing dose, and by 3) tailoring a motivational and parenting skills program directly to parents' and adolescents' skill levels and cultural background.
Aim 1: To determine the efficacy of a brief 8-week face-to-face group motivation plus family program versus a basic health program on decreasing z-BMI in overweight African American adolescents at post- group intervention (8 weeks).
Aim 2: To determine the efficacy of an 8-week on-line intervention vs. control on-line program that extends the dose of the group intervention on reducing z-BMI at post-on-line intervention (16-weeks) in overweight African American adolescents.
Aim 3: To determine whether the intervention effects on reducing z-BMI in overweight African American are maintained at a 6-month follow-up. It is hypothesized the adolescents in the 8-week motivation plus family group plus 8-week on-line intervention program will show the greatest maintenance in z-BMI reductions.
The proposed project targets underserved African-American families who have an overweight adolescent (>=85th percentile) in Columbia, South Carolina. Families are recruited through community partners, including pediatric clinics, community centers, and local schools. The study plans to enroll 520 families.
In phase I of the trial we test the
efficacy of an 8-week face-to-face group randomized trial comparing a
motivational plus family-based intervention (M+FWL) to a basic health (BH)
education program on reducing z-BMI in overweight African American adolescents.
In phase two of the trial participants are re-randomized to either an 8-week on-line intervention or control on-line program resulting in a 2 (M+FWL vs. BH group) x 2 (intervention vs. control on-line program) factorial design. This design allows us to test both the effects of the M+FWL curriculum and the added dose effects of the on-line intervention component on reducing z-BMI in overweight African American adolescents and their parents.
