Malnutrition includes both over nutrition and under nutrition. Country like Indiaharbours burden of both types. College students are highly vulnerable to malnutrition as they seem tobe nonchalant about their dietary habits, physical activity and general health due to academic burdenand lack of time. With increasing importance given to physical appearance one group of students areinto diet, consumption of dietary pills and bulimia. On the other hand another set of students areaddictedto junk food andsedentarylife and end up in overnutrition. Our study aim is a) To estimate the prevalence of malnutrition among medical studentsb) To assessthefactorsassociated with malnutrition amongmedical students.Acrosssectionalstudy was done among undergraduate medical students. Asemi-structuredquestionnairewasselfadministeredamong200studentsandalsoanthropometricexaminationwasconducted andBMI wascalculatedwiththe quetlet’s equation(weightinkgdivided by height in m2 ) The dietary habits and intensity and frequency of physical activity werequestioned.Thedatawasentered in an Excel sheet and theresults weretabulated.According to the WHO BMI scale , 13 students were underweight , 113 were healthy ,55 were overweight and 19 were obese . Obese and Overweight students were found to be morelethargicand had worsedietaryhabits than thehealthystudents.Obesity and overweight is quite common among medical students . Awarenessabout the ill effects of malnutrition has to be provided and medical students should be encouraged totake care of their health so that they can adapt to a healthy lifestyle and also practice the education ofhealthpromotion amongtheirpatients in future
