Background: The tobacco epidemic is one of the biggest public health threats the world has ever faced, killing more than 8 million people a year. An intention to quit is an important preliminary step for the behavioral change and it is highly associated with attempting to quit and with quitting. Therefore, this study examines the predictors of intention to quit and previous quitting attempts in Bahrain. Aim: To improve the overall quality of smoking cessation services in Bahrain. Objectives: 1) To study the prevalence of intention to quit smoking among adult smokers attending primary health care in Bahrain. 2) To explore predictors of an intention to quit and predictors of previous quitting attempts among adult smokers in Bahrain. Study design: Cross-sectional study. Settings: Data was collected from two primary care health centers in each health region in Kingdom of Bahrain using validated questionnaire. Participants 502 adult smokers aged ≥18 years, who were attending primary care within 10 days period in February 2018 (1st – 14th February), were included. Data was analyzed by using SPSS version 23.0. Results: We found that more than half of the smoker population (51.4%) are seriously thinking of quitting smoking in the next 12 months., while (70.9%) of them had previous quitting smoking attempts. Predictors noted to be significant in this study, include being a male, married, lower level of education, having shortness of breath and gastrointestinal symptoms. Conclusion: Results indicate high intention to quit smoking rate and along with the significant predictors found in this study, there is a great need to develop preventive and therapeutic interventions addressing these predictors to ensure higher rate of success and support the current tobacco smoking cessation services according to what predictors showed.
