Indonesia has one of the largest tobacco epidemics in Southeast Asia. According to the World Health Organization, smoking-related illnesses kill about 200,000 Indonesians annually. In Central Sulawesi, 26.1% are daily smokers and 6.0% are former smokers. The data show that a future burden of tobacco-related disease can be predicted if people still smoke. The objective of this study was to determine the factors related to smoking cessation in adults (aged 20-59 years old) in Palu City, Indonesia. The Health Belief Model was used as a conceptual framework to guide the study. This was a cross-sectional study and it was conducted with 183 adults. Data were collected by face-to-face interview using a structured questionnaire. Data were analyzed by using descriptive statistics, Chi-square, and logistic regression. The results revealed that significant predictors of smoking cessation included the perceived severity about the consequences of smoking (OR = 4.49, p < 0.001), attempts to quit (OR = 0.93, p < 0.001), and advice from peer/family/physician (OR = 0.32, p < 0.001), with R2 = 0.38. Health care providers can use the findings from this study as an evidence base to develop health promotion and prevention programs to encourage adults to quit smoking and so avoid developing diseases related to smoking. Furthermore, enhancing smoking cessation efforts in young smokers can significantly improve the health of the public.
