Body mass index and nutritional status of adult Savar tribals of Keonjhar District, Orissa, India.
A cross-sectional study was undertaken to determine sex differences in mean body mass index (BMI) and nutritional status (based on BMI), as well as the effect of age on BMI and nutritional status of adult Savars, a tribal population of Orissa, India. A total of 600 adult (aged > 18 years) Savars of four villages, namely, Bonianiposi, Morabali, Panchapolli and Sailong of Keonjhar District, Orissa, India, were studied. Height and weight were measured and BMI computed. Mean ages of both sexes were similar (men: mean = 38.9 years, sd = 15.3; women: mean = 38.0, sd = 13.9). Men had significantly greater mean height (p < 0.001), weight (p < 0.001) and BMI (p < 0.05). The prevalence (sex combined) of undernutrition (BMI < 18.5) was found to be very high (43.5%). Moreover, there was a significant (chi2 = 7.39, p = 0.025) difference in the prevalence of undernutrition between men (38%) and women (49%). Age was significantly (p < 0.001) negatively correlated with BMI in both sexes (men: r = -0.20; women: r = -0.16). In general, the frequency of undernutrition increased with increasing age. In conclusion, this study demonstrated that the prevalence of adult undernutrition was very high among Savar women and high among Savar men. These rates increased with increasing age. Therefore, from the public health point of view, immediate nutritional intervention programmes are needed for implementation among Savars, especially among older individuals. Moreover, further research is needed not only among this ethnic group but also other tribal populations of India to fully understand the causes and consequences of adult undernutrition.
