Women are generally vulnerable to undernutrition especially during pregnancy and lactation where the food and nutrient requirements are more during that period. The demographic consequences of the lower status in women have found expression in various forms such as female infanticide, higher mortality rate for women compared to men, lower sex ratio, literacy rate in female, lower level of employment of women as compared to men. The present investigation attempts to understand the health and nutritional status among indigenous Karbi tribal women of Karbi Anglong, Assam, Northeast India. The present community based cross-sectional investigation was undertaken among 150 Karbi women (aged 20-49 years) residing in rural areas of Diphu, Karbi Anglong Assam, using stratified random sampling method. Data on the anthropometric, socio-economic and demographic variable were collected using pre-structured questionnaire. Anthropometric measurements of weight and height were recorded using standard anthropometric procedures and Body Mass Index (BMI) was calculated using equation, BMI=Weight/Height2 kg/m2 . The nutritional status was assessed using proposed BMI classification for Asia Pacific population (WHO, 2000). The overall prevalence of obesity, overweight and undernutrition was observed to be 34.00%, 16.67% and 10.67%, respectively. The total prevalence of abortion or miscarriage and still births were observed to be 18.66% and 9.33%, respectively. Prevalence of abortion and still births were observed to be higher among obese women (p>0.05). Several socio-economic and demographic factors were not significantly associated with the nutritional status (p<0.05). There is scope of necessary improvement of the present health and nutritional status by introducing appropriate healthcare intervention strategies among women.
