Dietary practices of university students according to the Dietary Guidelines for the Brazilian Population: PADu study

Abstract

Objective To evaluate factors associated with dietary practices in students of a institution of higher education, included in the PADu study: “Anxiety and depression symptoms among university students in Minas Gerais: a longitudinal study”. Methods Cross-sectional study of PADu project baseline with undergraduate first period students, who responded in person to a printed and self-administered questionnaire. Dietary practices were evaluated through a 24 items scale based on recommendations of Dietary Guidelines for the Brazilian Population. Answer choices are four-point Likert scale: “strongly agree”, “agree”, “disagree” and “strongly disagree”. The sum of the items corresponded a score ranging (0-72 points), a high score indicating greater adequacy. The explanatory variables were: sociodemographics (gender, age, knowledge area, skin color, marital status, monthly household income), behaviors (excess alcohol consumption, physical exercise, screen exposure, internet use), health conditions (self-rated health, nutritional status, symptoms of depression, anxiety, stress). Adjusted multiple linear regression model was used to estimate the coefficients and their 95% CI. Results 356 students participated in the study. The average of dietary practices was 34.9±9.3 (0-63) points. Physical exercise practice (β: 3.75; CI: 1.83; 5.67) was associated with higher scores in the eating students score. We observed factors associated with the lowest score greater exposure to screens (β: -0.44; CI: -0.67; -0.13), excessive internet use (β: -3.05; CI: -5.22; -0.88), poor health self-assessment (β: -3.63; CI: -4.97; -1.21), excessive alcohol consumption (β: -2.09; CI: -3.92;-0.26) and stress symptoms (β: -2.81; CI: -4.72; -0.77). Conclusion Most students have inadequate dietary practices associated with internet use, alcohol consumption and stress.
