Association of ABO Blood Groups and Rh Systems with Body Mass Index, Body Surface Area and Body Fat Percentage.

Abstract

Background: The ABO blood group system is an important genetic marker in humans. Blood groups have been associated with susceptibility to various diseases and physiological characteristics. BMI, BSA and BF% are important parameters used to assess nutritional status, obesity, and overall health.

Aim: To analyse the association of ABO blood groups and the Rh system with BMI, BSA, and BF% among undergraduate dental students.

Methodology: A cross-sectional study was conducted among 155 undergraduate dental students aged 18–25 years. Blood grouping was carried out using the slide agglutination method. Anthropometric measurements were recorded using standard protocols. Statistical analysis was performed using Python version 3.11.4.

Results: A total of 155 undergraduate dental students participated in the study. Male students showed significantly higher BMI and BSA compared to females, while female students had significantly higher body fat percentage. Among the blood groups, AB blood group showed slightly higher median BMI and BSA values, whereas blood group O showed relatively higher body BF%. However, differences among blood groups were not statistically significant (p > 0.05).

Conclusion: Study suggests possible variations in body composition parameters among different ABO blood groups no statistically significant association was observed. Findings may help in understanding the relationship between genetic factors and anthropometric characteristics..
