          Abstract

          Objective To evaluate the nutritional status, food intake, eating behavior and physical activity level of college students in a medical college in Guangzhou, and to explore its association with dietary behavior.

          Methods A total of 263 students selected using stratified random sampling method from a medical college in Guangzhou were investigated by questionnaire from October to December in 2019. Chi-square test and Wilcoxon test were used to analyze group differences. Multivariate Logistic regression was used to analyze associated factors with thinness, overweight and obesity.

          Results The rate of thinness was 25.5%, and the rate of overweight and obesity was 11.8%. The intake of cereals, fruits, eggs, livestock, fried foods and carbonated drinks varied significantly by gender ( U = 3 278.00, 5 224.50, 5 981.00, 6 663.00, 5 460.00, 3 873.00, P<0.05). There was significant difference in total physical activity level in different grades ( U = 4 239.50, P<0.05). Multivariate analysis showed that egg intake was negatively correlated with emaciation ( OR = 0.20, P<0.01). Picky eating and partial eating were positively correlated with emaciation ( OR = 2.96, P<0.01). Eating fast was positively correlated with overweight and obesity ( OR = 5.35, P<0.05).

          Conclusion The detection rate of malnutrition among college students in this college is relatively high, and dietary behavior is associated with thinness, overweight and obesity.
