Abstract
Hemoglobinopathy is a major concern among the tribal population which constitutes 8.6% of the total population, and West Bengal (WB) is the home to 5.3 million tribes. The present study was conducted on 52,880 tribal school students from all the districts of WB. Written informed consent and peripheral blood were collected for complete blood count and high‑performance liquid chromatography analysis. Beta trait was 5.3%, sickle trait was 2.35%, and hemoglobin (Hb) E (HbE) trait was 1.4% in this population. About 37.8% of beta trait belonged to the Santal tribe and 21.5% belonged to Oraon. HbS is mainly found in Alipurduar and Jalpaiguri districts at the prevalence of 3.69% and 5.96%, respectively. HbE trait is found at 6.06% in Alipurduar, of which 51% of cases are from Mech tribe only found in this district. Unlike central and Western parts of India, HbS trait in WB was significantly low among the tribes. A high prevalence of consanguinity among the tribes is considered responsible for the high rate of hemoglobinopathy.
