Abstract

Abstract Background: Despite the rising popularity of vegetarian-ism, including in Saudi Arabia, there are relatively little data on the relationships between diet type, physical activity (PA) levels, and body composition, especially in young Saudi females. Aim of Study: To compare PA levels and body composition metrics in vegetarian and omnivorous female medical students attending the [redacted], Riyadh, Saudi Arabia. Material and Methods: One hundred and five students were enrolled, with a mean age of 21.86±2.02 years. Students were classified as omnivorous (n=63) or vegetarian (n=42). PA was measured using the International Physical Activity Questionnaire (IPAQ) short-form. Body composition [BMI, total muscle mass, total fat mass, total body water, protein, minerals, and basal metabolic rate (BMR)] were calculated using a bioelectrical impedance analyzer. Results: There were no significant differences in PA nor body composition variables between vegetarian and omnivo-rous students (all p>0.05). PA was significantly negatively correlated with BMI, total fat mass, and protein (all p<0.05) in omnivorous students, with weak, non-significant positive correlations between PA and body composition metrics in vegetarians. Conclusion: PA level and body composition variables were not significantly different between vegetarian and om-nivorous female medical students. PA was significantly cor-related with BMI, total fat mass, and protein in omnivores.
