Abstract

Introduction: Food choices affect physical and mental health. Environmental factors, such as social influence and access to food, are significant. Cognitive and biological factors, such as beliefs, preferences and genetic profile, also play an important role. Pourpouse: To assess how associations between chronotype and sleep quality may be associated with the dietary choices of nutrition students. Methods: This was a cross-sectional, qualitative and analytical study carried out with nutrition students between March and July 2022. Participants were university students over the age of 18, except pregnant women and people with severe cognitive impairment. Data was collected via online questionnaires on GoogleForms, disseminated via email and social networks. Questionnaires were used to characterize sociodemographics, calculate BMI, assess food choices, sleep quality and chronotype. The data was analyzed using SPSS with chi-square and Fisher's exact tests, with a significance level of 5%. Results: Data was collected from 80 nutrition students, with an average age of 22 ± 23 years. The majority were female, single and had a family income of between 1 and 3 minimum wages. Among the participants, 25.0% (N=20) were overweight, 63.75% (N=51) had inadequate eating habits and 33.8% (N=27) had sleep disorders. There was an association between chronotype and sleep disturbance (p=0.049), and between chronotype and food consumption (p<0.001), with 77.7% (N=14) of afternoon students having inadequate eating habits and 40.3% (N=25) of morning students making healthy choices. Conclusion: The university environment affects the quality of sleep and eating habits of students, which are often inadequate. Public health interventions are needed to deal with these problems.
