Magnitude of general obesity, abdominal obesity and related risk factors among medical students

Abstract

Abstract Introduction Obesity is recognized to be one of the greatest public health problems worldwide. In addition to physical health problems, obesity is also linked to an increased risk of mental health disorders. We aimed to estimate the magnitude of overweight/obesity among medical students, to identify their risk factors and to assess their impact on mental health. Methods We conducted a cross-sectional questionnaire survey among 524 medical students randomized from different levels, at the Faculty of Medicine of Sfax, Tunisia, on October 2019. Results The prevalence of combined overweight/obesity and abdominal obesity were 21.9% and 22.3%, respectively. The independent risk factors of overweight/obesity were male gender (OR = 3.2; 95% confidence interval (CI) = [1.96-5.2]), internship (OR = 2; 95% CI = [1.1-3.9]) and residency (OR = 3.2; 95% CI = [1.7-6]) levels, as well as moderate (OR = 3.4; 95% CI = [1.4-8.3]) and high (OR = 6.7; 95% CI = [2.6-16.9]) stress scale. However, daily fresh vegetables (OR = 0.4, CI95% = [0.2-0.8]) and high-fiber cereals whole-grain bread (OR = 0.5; 95%CI = [0.28-0.83]) consumption, light (OR = 0.37; 95% CI = [0.16-0.86]), moderate (OR = 0.24; 95% CI = [0.06-0.89]) and vigorous exercise (OR = 0.091; 95% CI = [0.01-0.74]) were independent protective factors of overweight/obesity. Severe consequences of obesity were noted, such as less ability to concentrate (37.9% vs 47.6%; p = 0.024), living under stress (72.2% vs 60.6%; p = 0.023), feeling unhappy and depressed (57.4% vs 44.7% p = 0.016), losing confidence (45.2% vs 20.5%; p < 0.001) and inability to enjoy normal activities (53.9% vs 38.7% p = 0.03). Conclusions Unhealthy lifestyle was relatively high among students with obesity. Our study confirms the data from the literature, and underlines the need to set up a plans including nutrition and lifestyle education in their curriculum. Key messages Unhealthy lifestyle was relatively high among students. The need to set up a plans including nutrition and lifestyle education.
