Background: Incidence rates of oral cancer in India are among the highest in the world mostly associated with lifestyle and food habits. Oral pre malignancies are also very common in tobacco users and about 10% of these undergo malignant transformation. Aim: The aim of the study was to assess the socio-demographic factors and magnitude of behavioral risk factors of fishermen population of Trissur district, Kerala, India. Materials and methods: A descriptive cross-sectional survey was conducted using a pre-designed and pre-tested questionnaire to assess the usage of alcohol, tobacco and its products among the fishermen community of Trissur dist, Kerala,India, from May 2014 to August 2014. Results: The study showed low socioeconomic(80.3%) and educational status(20.4% illiteracy) among the fishermen folks. The highest prevalence of tobacco smoking(40%), alcohol consumption(42.3%) and chewing tobacco(55%) was found more in age group of above 60 years. However pan masala use is highest among the men of age group of 20-40 years.(p = 0.001). Conclusions: The study results indicated high proportion of behavioral risk factors among fishermen subjects. Because of this high level of addiction to risk factors they are at increased risk of being oral cancer victims. We recommend health education for health promotion and immediate and effective implementation of national programs for tobacco and alcohol control policies .
