Ethnic differences in cancer risk behaviors through the transition out of high school.

Differences were assessed by ethnic group in the performance of cancer risk related lifestyle behaviors through the transition out of high school. Data were obtained from a nationally representative probability sample survey, the 1992 National Health Interview Survey-Youth Risk Behavior Survey. A cross-sectional sub-sample included adolescents with an age range from high school freshmen to young adults within four years after high school. Self reported indicators of diet, physical activity, cigarette smoking, smokeless tobacco use, alcohol use, and sexual practices were the primary dependent measures. Cancer risk increased at the transition out of high school through changes in cancer related behaviors. Hispanic-American males experienced somewhat higher risks after the transition for chewing tobacco and snuff. African Americans experienced somewhat higher risks after the transition for physical activity, chewing tobacco, and number of sexual partners. Further research needs to verify these findings with longitudinal designs, assessment of tracking of behaviors through the transition, and of the ecological, social and psychosocial correlates that may explain why these changes occurred.
