The overall goal of this study is to examine the relationships between cultural identity and identity-based motivation, physical activity, diet and obesity risk in African-American adolescents. It was hypothesized that African-American youth who self-report a bicultural identity maintain health promotion beliefs and behaviors that reduce obesity risk compared to minority youth who only identify with one culture or neither culture. It was also hypothesized that African-American youth who self report a bicultural identity are more likely to hold beliefs about health promotion behaviors that are congruent with their cultural identity than compared to youth who only identify with one culture or neither culture.
