Background:
Areca nut (AN) is one of the addictive substances known to cause deleterious effects on oral cavity as well as on various body organs including liver. But, scanty information is available reporting the adverse effects of AN chewing on the liver.
Aim:
To study the risk of liver disease in AN habitual based on the relevant published data.
Methods:
The literature search was performed by an electronic search of the PubMed/Medline, Scopus and Google Scholar databases using proper MESH headings and retrieved the articles published from 1998 to 2021. The eligibility criteria included: Human studies, AN habitual as study participants, use of controls and articles published in English. Data were extracted regarding characteristics of studies, characteristics of AN exposure, effect estimate and outcome of the studies.
Results:
Total 253 articles were identified from various databases and 15 studies were selected that met the inclusion criteria. Among these, thirteen studies showed an association between AN habit and attenuation of risk of liver disease as determined by relative risk/odds ratio/hazard ratio. Eleven studies described additive effect of AN and HBsAg and/or Anti hepatitis C virus status on development of liver disease. However, two of the studies showed opposite results. The heterogeneity in the study designs, exposure characteristics, outcomes and confounders precluded further meta-analysis.
Conclusion:
The association between AN chewing and an increased risk of developing liver disease is noted which necessitates the need for AN cessation campaign.
