Abstract

Background: Urbanization, shifts in diet, activity patterns because of rural-urban step migration can increase obesity and its associated diseases. Aim: To study anthropometric and body composition differences among rural and urban Ao Naga tribe and understand the correlation matrix between hypertension, haemoglobin of both sexes. Subjects and Methods:A cross-sectional method of anthropometric study was adopted for assessing the body composition and nutritional status of 1803 AoNagas, out of which 802 from urban and 1001 from rural area were selected. The mean age ± SD were 36.84 ± 14.1 for the urban settlers and 38.73 ± 14.9 for rural settlers. Result: Among males, both systolic blood pressure and diastolic blood pressure were higher in urban than rural males (p<0.05). The reverse is true for females. Hypertension, haemoglobin was more prevalent among rural population. Multivariate regression analysis for rural males showed age and body fat mass index (BFMI) as significant predictor of SBP (β= 0.258, R2= 0.157, p =0.016). For urban female, BFMI and age were significant predictors for SBP (β=3.646, R2= 0.353, p =0.000), and for the rural female, WSR, age and WHR were significant predictors for SBP (β=188.17, R2= 0.264, p < 0.000). Conclusion: Increasing rural-urban step migration among AoNagas result in changes in body composition variables which leads to higher WSR, overweight and obesity among them and anthropometric variables like age, %BF, BFMI, WSR and WHR were shown to impact systolic blood pressure.
