Abstract:
Objective To assess the nutritional status and dietary quality of medical students and its influencing factors.Methods Students from Shanghai Medicial College of Fudan University were recruited to complete the 7-day and 24-hour dietary records,with food consumption measured by weight.A comprehensive evaluation of the students'dietary quality was carried out by comparing their actual nutrient intake against recommended levels and calculating the component score of the Chinese Healthy Eating Index(CHEI).Factor analysis was used to extract dietary patterns.All subjects were further divided into high score group and low score group based on total CHEI.Binary Logistic regression was used to determine the factors influencing dietary quality.Results The study participants had an average daily energy intake of(2 057.02±501.87)kcal/d,80%from on-campus canteen meals.Carbohydrates,proteins and fats contributed to 48.90%,16.55%and 36.07%of the total energy intake,respectively.The CHEI median score was 67.55.Component scores for tubers,vegetables,fruits,dairy,fish and seafood,and nuts were below 60%,indicating an unbalanced diet.Being in the graduate stage(OR=0.53,95%CI:0.28-0.98)and having unreasonable body weight expectations(OR=0.37,95%CI:0.17-0.81)were associated with lower CHEI scores.Conversely,higher CHEI scores were associated with the fruit-dairy dietary pattern(OR=8.20,95%CI:3.39-19.84),the tuber-vegetable dietary pattern(OR=3.41,95%CI:1.58-7.32),and lower rates of on-campus dining(OR=1.92,95%CI:1.02-3.59).Conclusion The energy intake of students at Shanghai Medical College of Fudan University appears to be adequate.However,a relatively high proportion of energy supply from fat intake indicates a need for improvement in their dietary structure.The dietary quality of students is mainly influenced by their educational level,weight expectations and dietary patterns.
