Sociocultural aspects of areca nut use.

This paper aims to describe the sociocultural context of areca nut use through exploring people's norms and values and the meaning underlying a wide range of different practices. A historical review is followed by an examination of more recent evidence, including quantitative and qualitative research conducted in the United Kingdom. It is concluded that some reports involving the various uses of areca nut and the conclusions drawn are confusing and that future studies need to be more explicit. While a sound scientific background is required, important sociocultural and religious issues around areca nut use must also be understood if health promotion initiatives are to be considered.
