OBJECTIVES: Worldwide, cigarette Smoking is responsible for more than 5 million deaths and is expected to exceed 8 million by 2030. The objective of this study was to identify predictors of smoking in China India and Taiwan. METHODS: A cross-sectional study was conducted in convenient sample of adults using a pretested and validated questionnaire between 2008-2011 in China, India and Taiwan. Smoking status was ascertained among participants through one question inquiring if they had smoked cigarette within last 30days. RESULTS: A total of 2397 questionnaires were received. Approximately 44% of the participants reported that they smoked in the past 24 hours and around 48 % reported they smoked in the past 30 days.  The average age of the respondents was 33.5(±11). Smoking within 30 days was found to be significantly associated with male gender (OR=9.1; 95% CI= 2.751-30.132), Chinese nationality compared to Indian nationality (OR=29.104; 95% CI= 3.522- 240.531), smoking cigar (OR=23.334; 95%CI=4.152-131.122). Respondents were more likely to smoke if best friends offered cigarettes (OR=8.709; 95% CI=2.888-26.265), had siblings who smoke (OR=3.806; 95% CI=1.291-11.216), and were married  (OR=5.125; 95%CI=1.24 –21.26)  CONCLUSIONS: Smokers within last 30 days were significantly associated with being male gender, Chinese nationality compared to Indian nationality, married, having smoked cigars, accepting cigarette from a friend and having smoker siblings. These findings suggest the need for developing smoking cessation consultation and educational programs targeting individuals who are males,  married, and have smoker siblings. Also, smoking cessation program need to focus on individuals with friends who smoke. Smoking cessation programs must emphasize the harmful impact of smoking on health in short and long run. Chinese nationality was found to have higher likelihood of smoking, thus, there is a greater need for smoking cessation programs in China.
