Introduction: Chronotype reflects individual circadian preferences regarding sleep and wake schedules and has been associated with factors that may influence cardiometabolic risk.
Objective: To evaluate chronotype and anthropometric indicators of cardiometabolic risk in university students.
Methodology: An observational, cross-sectional, descriptive study was conducted among 59 university students. Chronotype was assessed using the Morningness-Eveningness Questionnaire. Body mass, height, and waist circumference were measured, and body mass index and waist-to-height ratio were calculated. Differences among chronotypes were analyzed using one-way analysis of variance, and the association with cardiometabolic risk was assessed using Pearson’s chi-square test and Fisher’s exact test.
Results: The intermediate chronotype was the most prevalent (67.8%), followed by the moderate morning (25.4%) and moderate evening (6.8%) chronotypes. Mean body mass index was 26.33 ± 4.62 kg/m², corresponding to the overweight category. No significant differences in anthropometric indicators were observed among chronotypes, nor was there a significant association between chronotype and cardiometabolic risk.
Discussion: The predominance of the intermediate chronotype was consistent with findings reported in other university populations. Although descriptive differences in anthropometric indicators and the proportion of participants with cardiometabolic risk were observed across chronotypes, these differences and associations were not statistically significant.
Conclusions: The intermediate chronotype predominated, and mean body mass index corresponded to the overweight category, with no significant anthropometric differences or association between chronotype and cardiometabolic risk.
