title: Knowledge, attitudes and beliefs of adult South Asians living in London regarding risk factors and signs for oral cancer.
abstract: BACKGROUND
  South Asian communities in the UK are thought to be a high-risk group for oral cancer, primarily because of betel-quid (pan) chewing habits. However there has been little research on the communities' perception of oral cancer.
  
  
  OBJECTIVE
  This investigation was undertaken to assess the knowledge, attitudes and beliefs of South Asian adults (n = 367) regarding the risk factors and signs for oral cancer.
  
  
  METHODS
  The information was obtained by means of a self-administered questionnaire and structured interviews at six Asian community centres and three general medical practices in north west London.
  
  
  METHODS
  Subjects ranged in age from 16 to 80 years and came from diverse socio-economic and cultural backgrounds.
  
  
  RESULTS
  Tobacco use was the only risk factor correctly identified by most adults (82%). A significant difference (P < 0.001) was seen in betel-quid chewing habit among the age groups with 42.2% of adults in the 50-80 year age group practising this habit as compared to only 5.3% in the 16-29 year age group. Another finding was that the traditional method of betel-quid chewing is being replaced with readily available processed areca nut and tobacco products.
  
  
  CONCLUSIONS
  There is extensive misinformation and a general lack of awareness about the risk factors and signs of oral cancer among the South Asian communities irrespective of age, gender, South Asian subgroup and social class. It is clear that betel-quid chewing is a common habit among the population and especially in the elderly population. It is recommended that health promotion advice be targeted to this population and their carers.
