Areca nut trade, globalisation and its health impact: perspectives from India and South-east Asia.

Abstract

Areca nut (AN) is consumed globally by 600 million people, and 10%-20% of the world population uses betel quid, a preparation containing areca nut. India and other South-east Asian countries are the largest consumers of AN in the world. The aim of this article is to review the economic impact and oral health effects of the consumption of AN. It will also discuss the role of dentists and auxiliary healthcare providers for increasing public awareness and the need for a strong public health policy. To address the concerned area, PubMed, Scopus and Google Scholar databases were explored from the year 1965 until 2017. Studies focusing on various aspects of AN only, and articles published in English were included. Anecdotal reports, case reports and unpublished data were excluded. This narrative review suggests India is the world's largest producer of AN along with the largest AN consuming population followed by other South-east Asian countries. AN chewing causes oral submucous fibrosis (OSF) and it is most commonly observed in people of India and South-east Asia. AN use is associated with various social and unsocial aspects. Dentists and dental auxiliaries can increase the knowledge and awareness of a health issue (OSF) among the target audience as well as the detrimental effects of AN chewing. There is a need for more aggressive public health measures and dentists and dental auxiliaries should be employed to bring awareness to the general public regarding AN use.
