Background: Auto-rickshaw drivers (ARDs) are under constant physical and mental pressure due to illiteracy, poverty, lack of awareness about hazards of addictions, and other factors that lead to various habits majority being tobacco use. Studies have found that tobacco use is very prevalent among ARDs in comparison to general population. Tobacco use is commonly associated with cancers. Oral Pre-Malignant Lesions (OPMLs) are the strongest risk factor for majority of oral cancers. We studied the prevalence of OPML among ARDs of Belagavi and their association with tobacco use. Methods: It was a cross-sectional study conducted among 600 regular ARDs of Belagavi City during January to December 2016. We selected two ARDs that were the last in line from 300 major auto-rickshaw stands. We adapted the questionnaire from Global Adult Tobacco Survey questionnaire. After getting informed consent, we collected the data by personal interview and performed an oral visual examination for OPML for all the study participants. Data were analyzed using SPSS software. Institutional Ethics Committee approved the study. Results: Prevalence of tobacco was 62.17%. One-third of participants (30.17%) had OPMLs. Leukoplakia (62.43%) was the most common lesion. OPMLs were significantly associated with tobacco use and duration of tobacco use. Conclusions: About 30% of ARDs had an OPML. Chewing tobacco, gutkha, lime with tobacco, and cigarette were significantly associated with OPML.
