Abstract
In a study of 2,135 university students, men exhibited a more pronounced eveningness preference compared to women.
- The distribution of morningness-eveningness preferences followed a normal curve, with scores ranging from 17 to 78 and a mean of 48.25.
- Among participants, 15.84% were identified as morning-types, 59.62% as intermediate-types, and 24.54% as evening-types.
- Significant differences were found between genders in mean MEQ scores and circadian typology distributions, with p-values less than 0.0001 and 0.00001, respectively.
- Factor analysis revealed three key elements related to circadian preference: time of greatest efficiency, sleep time/sleep phase, and awakening time/sleep inertia.
- Items sensitive to gender differences primarily belonged to the factors related to efficiency and sleep timing.
