Background and Purpose: The prevalence of youth obesity has increased dramatically in the United States, becoming a severe concern in Hawai`i and disproportionally impacting Filipino youth. The main study objective was to describe the influence of parents and friends on adolescents’ dietary, physical activity, and sedentary behaviors. Methods: We collected quantitative and qualitative data from two classrooms in Hawai`i, from ethnic minority adolescents (N=42; 11th and 12th graders) and their parents (N=31). Participating adolescents were 86% female with a mean age of 16.5 + .6 years, and their parents were 77% female with a mean age of 45.9 + 6.9 years. The majority of participants described themselves as Filipino American. Self-report data were collected via adolescent surveys and follow-up group discussion, as well as individual adolescent-led parent interviews. Quantitative data were descriptive, and qualitative data were conceptualized into underlying themes based on the targeted health behavior and the source of influence (parents and friends). Results: The majority of students reported parents as the dominant influence on their dietary and sedentary behaviors; however, friends were reported as the principal influence on adolescents’ physical activity levels. Parents’ reported a strong dietary influence via home availability, but minimal influence on adolescents’ physical activity. Conclusion: Home food availability and reduced television time are prime targets for family-based interventions among ethnic minority Hawai`ian populations.
