Epidemiological studies of blood groups in the district of Bankura with special reference to tribals

Area of Science:

• Anthropology
• Genetics
• Public Health

Background:

• ABO blood group system is crucial for transfusions and understanding population genetics.
• Previous studies have indicated variations in blood group distribution across different ethnic and geographic groups.

Purpose of the Study:

• To investigate the distribution of ABO blood groups in tribal and non-tribal populations of Bankura district, West Bengal.
• To compare the ABO blood group frequencies between these two groups.

Main Methods:

• A cross-sectional study was conducted involving 4301 subjects.
• Blood samples were analyzed to determine ABO blood group phenotypes.

Main Results:

• Blood group O was the most prevalent, observed in the highest number of subjects.
• Blood group AB was the least prevalent, found in the smallest number of subjects.
• No statistically significant differences in ABO blood group distribution were found between tribal and non-tribal populations.

Conclusions:

• The ABO blood group distribution in Bankura district follows a general pattern with O being most common and AB least common.
• The findings suggest a lack of significant genetic differentiation in ABO blood group alleles between the studied tribal and non-tribal communities in this region.
