Obesity is a significant problem in African-American adolescents in the United States (US). The most recent data suggests a doubling of overweight (BMI percentile > 85th for age and gender) and obesity (BMI percentile >95th for age and gender) among these racial/ethnic minority youth in the last 10 years. In 2007-8, 39.5% of African-Americans a ages 12-19 were overweight and 24.4% were obese. These obesity rates were approximately double that of non-Latino whites. Until now, most of our efforts to reduce pediatric obesity have targeted at-risk youth who are physically inactive and over-consume energy dense foods. More recently, however, that focus has broadened as a result of new understanding about how cultural factors also shape physical activity behaviors and dietary patterns. With the rapid increase in cultural diversity of the US, Black culture is quickly becoming a part of mainstream American culture, evolving within the US, while simultaneously integrating aspects of different African and Black American cultures. Consequently, African- American youth who come of age in the US, a multicultural society, interact with people from different cultural backgrounds that can lead to an interchange of cultural attitudes, beliefs and behaviors. Specifically, these youth may adopt one of four general cultural identities: (a) bicultural identity-combining aspects of their family's culture with aspects of mainstream American culture; (b) US cultural identity- replacing their family's culture with mainstream American culture; (c) traditional cultural identity- retaining their family's culture while rejecting mainstream American culture; or (d) marginalized cultural identity- becoming alienated from both cultures. Biculturalism is considered the most adaptive process allowing individuals to function effectively in a multicultural society while still maintaining supportive connections to their own family's culture. Hence, it was hypothesized that racial/ethnic minority 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.
