Smoking cessation patterns and predictors among adult Californians of Korean descent.

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.
