Prevalence of Obesity in Medical students and its correlation with cardiovascular risk factors: Emergency Alarm for Today?

Abstract

BackgroundIt is predicted that the prevalence of overweight and obesity will rise significantly by 2015 in young population. Problem of overweight and obesity has been recognized as public health problem worldwide due to the fact that it increases the risk of chronic diseases such as Cardiovascular Diseases (CVD), stroke, diabetes, sleep apnoea, osteoarthritis etc. ObjectiveTo assess the body mass index in medical students and its association with various cardiovascular risk factors like blood pressure, dietary habits, and family history of cardiovascular diseases. MethodA university based cross-sectional analytical study was conducted in Department of Physiology, Smt. B.K. Shah Medical Institute & Research Center, Vadodara, Gujarat. Data was collected through convenient sampling technique by using selfadministered questionnaire followed by anthropometric measurement. Body Mass Index (BMI) of 138 first year medical students was assessed. Systolic blood pressure, diastolic blood pressure, pulse pressure, mean blood pressure, pulse rate and arterial oxygen saturation were measured. ResultData was compiled in excel sheet, analyzed for percentage and proportion. Chi square and Pearson correlation test were also applied and alpha error was set at 5% level. In comparison to the students with normal BMI, students with BMI >25 kg/m 2 (N=49) showed significantly high blood pressure indices. Dietary habits and family history of cardiovascular diseases were also noted. Highly significant association of high BMI was found with elevated blood pressure (X 2 =7.4042***, p<0.001) and presence of family history of cardiovascular diseases X 2 =9.8625***, p<0.001). BMI is negatively correlated with SpO 2 (r= -0.0504, p<0.05) and pulse rate, while positively correlated with systolic blood pressure (r=0.2736) and diastolic blood pressure (r=0.0275). ConclusionIn conclusion, majority (more than 35%) of medical students were overweight, high prevalence of cardiovascular risk factors like family history, elevated blood pressure and less SpO 2 .

Blood pressure measurement in overweight, underweight and normal BMI undergraduate students of a private medical college: correlation of BMI with blood pressure

“…The study is similar to studies done earlier which have reported similar correlation between BMI and blood pressure. 26,27 The results may be explained on the basis that with increase in BMI there is increase in sympathetic nervous system activity, endothelial dysfunction and increase in cytokines. 28 Limitation of this study analysis of dietary habits, physical activities and stress faced by the students will yield better results.…”

Study of Body Mass Index among Medical Students of a Medical College in Nepal: A Descriptive Cross-sectional Study

“…Similar studies that calculated BMI of medical students have been conducted in India, Pakistan, Poland, United Arab Emirates and Greece. [8][9][10][11] Amatya et al 12 in their study found that 18.31% medical students underweight, 77.18% normal, 4.23% overweight, and 0.3% obese (one male student).…”

Determinan Perilaku Konsumsi Makanan Siap Saji (Fast Food) Pada Siswa di SMA Negeri X Jakarta Timur Tahun 2020

“…3 Sebanyak 54,40 % siswa menyukai makanan siap saji (fast food) dan lebih dari 60% siswa tidak menyadari mengenai fakta bahwa makanan siap saji (fast food) adalah makanan yang tidak sehat. 4 Hasil survei yang dilakukan oleh Lemia dan Dalal (2019) Penelitian ini dapat dijadikan sebagai masukan dan bahan untuk penelitian selanjutnya, peneliti selanjutnya juga dapat melakukan intervensi dan mengembangkan penelitian ini mengenai konsumsi makanan siap saji pada siswa di SMA Negeri X Jakarta.…”
