Background: We are facing a rising trend of NCDs (Non-communicable diseases) associated with sedentary lifestyle. Students who are obese or develop obesity during college years are at increased risk for continued obesity throughout adulthood. Present study was conducted with an objective to study prevalence of sedentary lifestyle among college students and its epidemiological correlates, in particular with the association with hostel residence. Methodology: Cross-sectional analysis of 50 female residential students of age ranged from 19-22 years was conducted for assessment of BMI and Physical activity level by Global Physical Acivity Questinnaire (GPAQ). Informed consent was obtained prior. From GPAQ questionnaire Physical activity level and BMI data was collected and analysis was done. Result: Out of 50 subjects 26% subjects were having vigorous PA. 62% subjects were having moderate PA. 12% subjects were having low PA. Out of 50 subjects 42% subjects were in normal categories. 10% subjects were Overweight. 48% subjects were Underweight. Discussion: In present study, reason for poor physical activity level in 12% students may be physical inactivity during the daily routine and travel domain. They can be encouraged to improve their physical activity level on daily basis. College activities should include compulsory extra-curricular activities to be undertaken by the students such as including sports, athletics, aerobics or yoga. Conclusion: 12% subjects were found to have low PA. 10% subjects were Overweight. 48% subjects were Underweight. There is still a need to encourage students in residential college to be active on routine basis to prevent shattering burden of non-communicable diseases in society.
