Objective To explore the results of the survey on eating habits and nutritional status of university students and the correlation analysis between different lifestyles and body composition.
Methods College students enrolled in a university were selected as the study subjects, and a total sample size of 993 cases was included in this study from November 2021 to December 2021 to analyze the effects and correlations of different lifestyles on body composition through questionnaires as well as body composition measurements.
Results (1) Living habits. 3.02% of students smoked cigarettes, 9.96% of male students smoked cigarettes, and 0.42% of female students smoked cigarettes; 17.42% of students drank alcohol; 47.83% went online for 2-3h per day, and those who went online for ≥4h were 16.01%, 48.54% studied for 9-10h per day, and 20 48.74% of students slept less than 7h;(2) Analysis of the questionnaire on the frequency of raw and simplified food for college students. 46.32% of college students could manage to eat vegetables every day, 31.02% of college students could ensure that they ate fruits 3-4 days a week, 21.15% of college students hardly ate fish and shrimp, and 16.11% of college students could ensure that they ate dairy products every day. In terms of the frequency of major food intake types per week, there was a significant difference between male and female students in terms of the frequency of food intake types, except for soya bean products (P < 0.05);(3) Analysis of body composition of college students. The percentage of male students' body fat is significantly lower than that of female students (P < 0.05), and the percentage of male students' body water, body protein, and body mineral is higher than that of female students (P < 0.05); the rate of female students' insufficient body water content, the rate of insufficient protein content, and the rate of body fat content exceeding the standard are higher than that of male students (P < 0.05);(4) Analysis of nutritional status of college students. The hidden obesity of female students is significantly higher than that of male students (P < 0.05). The percentage of malnutrition in male students is higher than that of female students (P < 0.05);(5) Correlation analysis of body fat and protein content of university students with lifestyle. The frequency of fruit consumption was an independent influence on the body fat and protein content of college students (P < 0.05).
Conclusion College students' dietary structure is unbalanced, and sleep time is generally shorter, most college students' body protein content is insufficient, and female college students' hidden obesity problem is prominent, and increasing the frequency of fruit consumption can effectively improve the proportion of protein in college students' body.
