This study presents population estimates of cigarette use among adults of Korean descent residing in California. Data were drawn from telephone interviews with adults (N=2,830) developed from a random sampling of listed persons in California with Korean surnames. A total of 86% of attempted interviews were completed, and 85% of the interviews were conducted in Korean. Less acculturated men and more acculturated women reported higher present and predicted future rates of smoking after multivariate statistical controls were applied. Sharply divergent rates of cigarette use were found between the genders. Although men did not smoke their first cigarette or smoke cigarettes regularly earlier than women, both groups began smoking later than adults born in the United States. To be effective, tobacco intervention efforts must be tailored specifically to cultures of each minority. Results suggest that acculturation processes influence tobacco use differentially by gender, and future research is needed to identify the implications of processes in tobacco initiation and cessation.

This paper describes smoking cessation among adult California residents of Korean descent, based on a telephone survey (N = 2,830). The overall quit rate (number of former smokers divided by number of ever-smokers) was 55.0% (55.8% among males and 49.6% among females). Acculturation was negatively associated with 90-day abstinence after controlling for demographic, social support, health belief, environmental, lifestyle, and respiratory illness history variables (OR = 0.59, 95% CI = 0.38-0.91). Those with lower acculturation, higher body mass index, a social network discouraging smoking, home smoking restriction, correct beliefs about smoking harm, and significant concern about one's health were most likely to quit smoking for 90 days or longer. Results suggest that social and situational conditions should be included in the design of smoking cessation interventions among Koreans.

This research examines the influence of messages from religious leaders and congregants on whether Korean women are overweight or obese. Data were drawn from telephone interviews with a probability sample (N=591) of women of Korean descent living in California. Overweight or obese prevalence was measured using World Health Organization standards for Asians (BMI>23). Respondents reported the frequency of messages discouraging "excessive eating" or encouraging "exercise" from religious leaders and congregants during a typical month. When conditioned on leaders' messages, the frequency of congregants' messages was associated with a significantly lower probability of being overweight or obese, although messages from either in the absence of the other were unassociated with being overweight or obese. At least for Korean women, religion may help prevent obesity via religious-based social mechanisms.

This study describes aerobic exercise and walking for exercise behaviors among the Korean American population, a rapidly growing minority. Data for this study were drawn from a representative survey of Californians of Korean descent (N = 2,830) conducted by telephone; 86% of eligible participants completed interviews in either Korean or English. Sample characteristics closely approximated those for Koreans in the 2000 United States Census for California. The data show that 32.8% of Koreans vigorously exercise or walk for exercise, but walking regimens and more vigorous modes of exercise are employed by different subgroups. Women, less acculturated, married persons, and less well educated are particularly low in vigorous exercise. Korean Americans walk for exercise much less than majority groups, although they engage in vigorous physical activity on a roughly equivalent basis. Interventions to promote physical activity should be adapted not only for the Korean culture but also for specific subgroups defined demographically.
