Abstract
OBJECTIVES: This cross-sectional community based study was conducted to estimate the prevalence of consumption habits for non tobacco pan masala (ASU) and the risk of developing oral precancer in North India. METHODS: This study was conducted in the old town of Lucknow city in the state of Uttar Pradesh in India. Subjects residing for more than 6 months and aged 15 years or above, were enrolled in the study after their informed consent. A two page survey tool was used to collect the data. A three times more matched sample of non users was randomly obtained from this data to analyze and compare the final results. RESULTS: 0.45 million subjects were surveyed. Majority of tobacco users were in the age group of 20-35 years among males and 35-39 years among females. Consumption of non tobacco pan masala among males as well as females was most common in 15-19 years of age group. Prevalence of oral precancer (leukoplakia, submucous fibrosis, erythroplakia, lichen planus, smokers palate and verrucous hyperplasia) was 3.17% in non tobacco pan masala users and 12.22% in tobacco users. The odds of developing oral precancer in non tobacco pan masala users was 20.71 (18.79-22.82) and in tobacco users was 88.07 (84.02-92.31) at 95% confidence interval against non users of both. CONCLUSION: The odds of developing oral precancer even with consumption of pan masala is high, even when it is consumed without tobacco. It is hence recommended to discourage this habit.
