BACKGROUND: The prevalence of smoking continues to be higher in some ethnic groups than in others, despite the overall decrease of smoking during the last 30 years. The goal of this project was to investigate the trends and predictors of cigarette smoking among a population of Caucasians, Japanese, Chinese, Filipino, and Native Hawaiians. METHODS: We combined data from 19 earlier studies conducted in Hawaii between 1975 and 2001. After excluding 1,885 individuals without smoking data, 158,629 subjects (40.0% Japanese, 30.3% Caucasian, 14.3% Hawaiian, 8.1% Filipino, 3.0% Chinese) were included in the analysis. The prevalence of current smoking and past smoking was estimated for 5-year periods by sex and ethnicity and age-adjusted to the state's population. We calculated odds ratios and 95% confidence intervals by using polytomous logistic regression to explore determinants of smoking, while controlling for clustering by study. RESULTS: Men were more likely to smoke than women throughout the study period, but they experienced a greater decline in smoking until 1994. We observed a small increase in smoking prevalence thereafter. Native Hawaiians reported the highest smoking prevalence, Japanese the lowest, and Caucasians intermediate levels. Graduate level education had the strongest inverse association with current and past smoking. Older age at interview, being married, and a higher body weight were related to lower smoking prevalence. CONCLUSIONS: Our data suggest a modest reversal in the declining smoking prevalence during the late 1990s. The persistent ethnic differences require new approaches that reach those groups who remain at high risk for adverse health effects from smoking.
