Background: Physical activity (PA) is one of the modifiable factors that is associated with the risk of type2 diabetes mellitus (T2DM). This study aimed to compare the level of PA assessed by using two subjective methods of PA assessment and to explore the effect of physical activity on the anthropometric indicators of T2DM in Bengalee young adult females. Methodology: This study was conducted on 114 Bengalee young adult females from Kolkata and surrounding areas. General socio-demographic information was collected in a pre-designed schedule. Level of PA was assessed by using International Physical Activity Questionnaire- Short form (IPAQ-SF) and values of Physical Activity Level (PAL). Indicators of T2DM in terms of Waist Circumference, and Body Fat Percentage of the participants were measured and BMI and Waist to Height Ratio were computed. Results: The mean age of the participating volunteers was 19.9 years. Study findings indicated that more than 70% of the participants was physically inactive. The spearman’s correlation coefficient values of PA assessed using IPAQ and PAL was statistically significantly correlated (P < 0.05). The correlation coefficient between predicted and assessed criterion value was 0.61. Mean BMI (kg.m-2), WC (cm), WHtR and BF (%) of the participants were 23.71, 84.8, 0.53 and 30.12 respectively. Conclusion: The physical activity as assessed by two methods of PA assessment was positively significantly (P<0.05) correlated. Physical activity was inversely significantly related with BF (%) in the present study.
