Areca nut use following migration and its consequences.

Area of Science:

• Epidemiology
• Public Health
• Oncology

Background:

• Areca nut consumption affects 20% of the global population, particularly in Oriental countries.
• Combined use of areca nut and smokeless tobacco (ST) is common in Indo-Chinese regions.
• Migrant studies are crucial for understanding environmental exposures in cancer etiology.

Purpose of the Study:

• To review the prevalence of areca nut chewing among migrant populations.
• To examine the health consequences associated with areca nut and ST use in migrant communities.
• To assess the role of areca nut and ST in the etiology of cancers and other diseases.

Main Methods:

• Review of available data on areca nut chewing prevalence in migrant populations.
• Analysis of studies on Indian migrants in various global locations.
• Examination of health outcomes in Asian ethnic groups in the United Kingdom.

Main Results:

• High prevalence of areca nut (often with ST) consumption observed in Indian migrants and Asian communities globally.
• Increased risk of oral cancer in migrant populations due to areca nut and ST use.
• Evidence suggests areca nut and ST contribute to cardiovascular disease, hypertension, and diabetes in UK-based Indians.

Conclusions:

• Areca nut and ST use among migrants leads to excess oral cancer risk.
• Combined areca nut and ST use may be a significant factor in cardiovascular disease, hypertension, and diabetes.
• Psychological addiction and dependency syndromes are associated with areca nut and ST use in immigrants.
