RESUMO
Objective@#To investigate the correlation between body composition and eating habits among medical students, and to provide evidence for health promotion.@*Methods@#In December 2021, stratified cluster random sampling method was used to conduct a questionnaire survey and body composition assessment among 445 students in grade one to grade four in Jining Medical University.@*Results@#There were 152 girls (53.3%) and 45 boys (28.1%) with low skeletal muscle mass. Totally 167 students ( 37.5% ) had lower muscle mass, including 115 females (40.4%) and 49 males (30.6%). High body fat percentage was found in 259 (58.2%) students, including 179 females (62.8%) and 80 males (50.0%). There were 192 students (43.1%) with abnormal waist to hip ratio, with 139 females (48.8%) and 53 males (33.1%). In addition, emotional eating score of female students was significantly higher than that of male students(6.85±2.24, 6.11±2.69, t =2.96, P <0.05). Cognitive restricted eating was positively correlated with skeletal muscle mass and musde mass( r=0.13, 0.13, P <0.05). Emotional eating was positively correlated with body fat percentage, body fat and waist hip ratio( r =0.20, 0.20, 0.16, P <0.05). Unrestricted eating was positively correlated with body fat percentage, body fat and waist hip ratio( r =0.15, 0.18, 0.15, P <0.05). Multiple linear regression analysis showed that gender, family residence, physical activity and cognitive eating were associated with skeletal muscle mass and muscle mass of medical students( P <0.05).@*Conclusion@#With low skeletal muscle mass, low muscle mass, body fat percentage and waist and hip high ratio, reasonable eating habits combined with resistance exercise should be adopted to improve their physical health.
