Sexual dimorphism of Socio-economic status, Nutritional status and hypertension among the Oraon tribe of Paschim Medinipur, West Bengal, India

The nutritional status and socio-economic profile of tribal people is an important issue in India due to their marginalization from main stream population with respect to various facilities. This paper deals with the assessment of socio-economic status and health status among adult males and females of Oraon tribes. A community based cross sectional study was conducted among Oraon tribal people (N=100) from Oraon Para of Tantigeria, Paschim Medinipur, West Bengal, India. The overall prevalence of under nutrition (BMI < 18.5) was very high (56%). The prevalence was significantly higher in male than the female (72.0% vs. 40.0%; p <0.001). Sex wise mean differences was found in all anthropometric indicators (p= <0.001 & P= <0.01) except weight. The mean SBP, DBP and MAP increased with increasing BMI level. BMI category wise differences found between SBP, DBP& MAP among male and female (p=<0.001). Pearson correlation coefficient shows that very high significant association between all anthropometric and physiological variables (p= <0.01) except height wise SBP, DBP & MAP. This population was facing severe nutritional stress.
