Exercise Adherence in Hispanic Adolescents with Obesity or Type 2 Diabetes

Purpose: Hispanic adolescents experience high rates of obesity and type 2 diabetes. The purpose of this study was to examine adherence to a 16-week personalized exercise intervention and the perception of family support for exercise, benefits and barriers to exercise and overall health in Hispanic adolescents diagnosed with obesity or type 2 diabetes. Design and methods: Using a secondary analysis of a larger feasibility trial, data from 21 Hispanic adolescents, 13 with T2D and 8 who were obese and 14 that completed the entire 16-weekstudy (7T2D; 7 obese) were analyzed. Adolescents wore an ActigraphTM accelerometer for tracking exercise throughout the 16-week intervention. Results: The adherence rate for the intervention was 59% for those with T2D and was 88% for those with obesity. Overall perceptions of health improved for those completing the 16-week intervention. Barriers to exercise were negatively associated with moderate-to-vigorous physical activity and were higher in those with T2D. Conclusions: Adolescents with T2D were less adherent to their personalized exercise program than those who were obese. Practice implications: Strategies that address cultural preferences and family engagement are needed to address barriers to exercise for Hispanic youth, particularly those already diagnosed with T2D that have high risks for early onset of disease complications.
