The purpose of the study was to compare the Body Mass Index (BMI) of the sedentary female teachers related to the selected four disciplines General College, Medical College, Management College and Engineering College. The total eighty (twentysedentary female teachers from each discipline) female subjects ranging from 30 to 45 years (Mean ± SD; Age 42.34 ± 0.54 years, Height 1.59 ± 0.01 metre, Weight 65.28 ± 1.17 kg) of age were selected from the different colleges of NCR region (i.e., Delhi, Ghaziabad, Muzaffarnagar and Meerut). The subjects were tested by BMI method to categorize them according to the Indian norms of BMI. To compare all the means of BMI scores measured from sedentary female teachers in selected disciplines, one way analysis of variance (ANOVA) was used at the level of significance was set at 0.05. There was significant difference found between the BMI of the sedentary female teachers from selected disciplines. Since, the one way analysis of variance was found significant, the least significant difference (LSD) test was calculated. The Post Hoc test showed that the difference between General College Teachers and Medical College Teachers on their in terms of means of Body Mass Index is significant at 5% level, as the p-value for this mean difference is 0.00 which is less than 0.05. Similarly, the p-value for the significance of difference between General College Teachers and Management College Teachers on their in terms of means of Body Mass Index is significant at 5% level; the p-value is 0.00, which is less than 0.05. However, there is significant difference between the means of the General College Teachers and Engineering College Teachers as far as Body Mass Index are concerned because the p-value is less than 0.05.
