Abstract	Investigated the association of the morningness-eveningness dimension in individuals with behavioral and health aspects in a sample of undergraduate students. The morningness-eveningness dimension in humans has been shown to influence social behavior and individual health. A total of 372 students (aged 18-29 years; 66.7% females) participated. Demographic data was assessed. Measures included the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Morningness/Eveningness Questionnaire (MEQ), the Alcohol Use Identification Test (AUDIT), and the Self-Reporting Questionnaire (SRQ-20) to assess minor psychiatric disorders. Among the participants, 92.2% did not smoke, 58.9% engaged in physical activities, and 19.7% were night-shift workers. In regard to morningness-eveningness, 55.9% of the participants were found to be intermediate types, between evening (39.5%) and morning (4.6%). Poor sleep quality (OR = 1.89), minor psychiatric disorders (OR = 1.92), and tobacco consumption (OR = 3.65) was more evident among evening types. Evening types were mostly male (OR = 1.72). Results from this study suggest that evening types are more vulnerable to sleep and psychiatric disturbances, and they tend to smoke more than morning types. (ZPID).
