Abstract

Background: WHO data on increased CVDs in India is estimated to be one of the greatest of any country in the world. The Nicobarese tribes of India are indigenous tribes, habited in difficult to reach, rural, and remote Islands in the Bay of Bengal.

Methods: A community-based cross-sectional study was conducted among 365 Nicobar Tribes using WHO HEARTS risk prediction charts to study the distribution and determinants of NCD risk factors and to predict the 10-year CVD risk.

Results: 66.8% were obese, 24.4% were smokers. Smokeless tobacco use was prevalent among 74.8 and 62.5% reported alcohol consumption. Based on the non-laboratory component of the CVD risk assessment chart, 83 (22.7%) had a risk <5%, 132 (36.2%) had a risk of 5-9%, 114 (31.2%) had a risk of 10-19%, 34 (9.3%) had a risk of 20-29%. Illiteracy (aRR: 2.24, 95% CI: 1.34 to 3.78, p=0.002) and lower vegetable consumption (aRR: 1.71, 95% CI: 1.04 to 2.81, p=0.035) were associated with a CVD risk score of 10-19%. Employment and lower vegetable consumption were associated with a higher risk score of ≥20% (aRR: 2.59, 95% CI: 1.14 to 6.01, p=0.024).

Conclusions: The prediction of 10-year CVD risk levels shows moderate to high CVD risk levels are higher among Nicobarese tribes than reported levels among general populations. Illiteracy, lower level of educational status, consumption of alcohol, and low consumption of vegetables in the diet are the main predictors of such moderate to high CVD risk levels.
