Objective-Although ethnic diVerences in adolescent smoking have been well documented, smoking among multiethnic adolescents has received little research attention. This study examined smoking prevalence and tobacco related psychosocial risk factors among multiethnic adolescents in California, as compared with white, African American, Asian American, and Hispanic adolescents. Design-This study used a cross sectional design. Data were obtained from the independent evaluation of the California Tobacco Control, Prevention, and Education Program. Setting-Students completed a paperand-pencil survey in their classrooms. Subjects-Data were collected from a stratified random sample of 5072 eighth grade students (age 13-14 years) in California during the 1996-97 school year. The data were weighted by school enrollment in analyses to make the estimates representative of the population of California students attending public schools. Main outcome measures-Outcome variables included self reported smoking prevalence, susceptibility to smoking, access to tobacco, and related attitudes, beliefs, and behaviours. Ethnicity was assessed with a self reported, "check all that apply" question. Results-Results indicated that multiethnic adolescents were at higher risk than single-ethnic adolescents on several variables, including 30 day cigarette smoking prevalence, lifetime smokeless tobacco use, buying cigarettes, receiving cigarette oVers, and expected friends' reaction if the respondent smoked. For several other variables (lifetime cigarette smoking prevalence, susceptibility to smoking, and number of friends who smoked), Hispanic adolescents were at higher risk than all other ethnic groups including multi-ethnic adolescents. Although susceptibility to smoking was highest among Hispanics, multi-ethnic adolescents scored significantly higher on susceptibility than the three other single-ethnic groups. Conclusions-Multi-ethnicadolescents may be at increased risk for smoking and may have easier access to cigarettes. Culturally targeted smoking prevention interventions for adolescents should address the unique social challenges faced by multi-ethnic adolescents that may increase their risk for smoking.(Tobacco Control 2000;9(Suppl II):ii9-ii14)

Objective: To examine the odds of overweight and related correlates in Chinese adolescents. Method: Cross-sectional study in 9023 adolescents. Results: Chinese youth were more likely to be overweight if they spent more time being sedentary; slept <7 hours/night; were male; were younger; participated more in vigorous physical activity; and had higher levels of parental education, a higher frequency of veg-etable intake, and a lower frequency of sweet/fast food intake. Conclusions: Overweight-related correlates seem to play different roles in the Chinese culture than in Western cultures. This may be due to culture-specific perceptions and changes in lifestyle accompanying socioeconomic transitions.
