Background: Oral Cancer is a major public health problem in most of the South East Asian countries including Sri Lanka. Use of tobacco in the form of smokeless tobacco and smoking, use of alcohol and betel quid chewing are the major contributory factors for causation oral cancer. The aim of this study was to investigate the prevalence of lifestyle factors responsible for causation of oral cancer and Oral Potentially Malignant Disorders (OPMD) in the Sabaragamuwa province of Sri Lanka. Methods: A cross-sectional community based study was conducted in Sabaragamuwa province by interviewing, then conducting an oral examination, on 1029 subjects over 30 years of age, over a one year period from November 2006. The study protocol included an interviewer-administered questionnaire to gather socio-demographic factors, recording of habits that included areca/betel chewing, smoking, and alcohol consumption. A three-day food diary was obtained, particularly to assess the consumption of tea, fruits and vegetables. The weight and height of residents was taken for calculation of Body Mass Index (BMI). Results: One hundred and two individuals with one or more OPMD were detected among these 1029 subjects. The prevalence of OPMD, weighted according to the estate sector and gender, was estimated as 11.3%. The prevalence of daily betel quid chewing in this study was 53.8%: 15.7% without tobacco and 47.4% with tobacco. The prevalence of individuals who reported consumption of alcohol at least weekly was 13.4%. A significant minority, 31.7%, were under nourished, with a BMI < 18.5. Forty six percent of the males practiced combined habits of betel quid chewing, smoking and regular use of alcohol. Conclusions: This study discloses high prevalence of OPMD and of lifestyle factors for oral cancer in these communities. There is an urgent need for a comprehensive strategy to control the use of tobacco, betel quid chewing and alcohol for prevention of oral cancer.
口腔癌是包括斯里兰卡在内的大多数东南亚国家的一个主要公共卫生问题。无烟烟草、吸烟形式的烟草使用、酒精使用和槟榔咀嚼是导致口腔癌的主要因素。本研究的目的是调查斯里兰卡萨巴拉加穆瓦省导致口腔癌和口腔潜在恶性疾病（OPMD）的生活方式因素的患病率。方法：2006年11月起的一年时间里，在萨巴拉加穆瓦省对1029名30岁以上的受试者进行访谈，然后进行口腔检查，开展了一项基于社区的横断面研究。研究方案包括一份由访谈员填写的问卷，以收集社会人口学因素，记录包括槟榔/槟榔咀嚼、吸烟和饮酒在内的习惯。获取了一份为期三天的食物日记，特别是为了评估茶、水果和蔬菜的摄入量。测量了居民的体重和身高以计算体重指数（BMI）。结果：在这1029名受试者中，检测出102名患有一种或多种OPMD。根据种植园部门和性别加权后，OPMD的患病率估计为11.3%。本研究中每日槟榔咀嚼的患病率为53.8%：15.7%不伴有烟草，47.4%伴有烟草。报告至少每周饮酒一次的个体患病率为13.4%。相当一部分人（31.7%）营养不良，BMI<18.5。46%的男性有槟榔咀嚼、吸烟和经常饮酒的综合习惯。结论：本研究揭示了这些社区中OPMD和口腔癌生活方式因素的高患病率。迫切需要一项全面战略来控制烟草、槟榔咀嚼和酒精的使用，以预防口腔癌。
