Sleep disturbances associated with minor psychiatric disorders in medical students

We performed a cross-sectional study with 342 medical students (age range, 18-35 years) to identify, among a group of sleep disturbances. those which are related to minor psychiatric disorders in this population. The instruments employed for data collection were the self-reporting questionnaire (SRQ-20), the morningness/eveningness questionnaire, the Epworth sleepiness scale, and a general questionnaire regarding demographic characteristics, use of drugs, history of psychopathology, usual fall-asleep time, usual wake-up time, amount of sleep, arousal during the night, and insomnia. We used a logistic regression model to deter-mine independent factors associated with minor psychiatry disorders. Daytime sleepiness [odds ratio (OR), 2.12; 95% CI, 1.21-3.71], arousal [OR, 4.54; 95% CI, 1.97-10.47]. insomnia [OR, 2.45 95% CI, 1.32-4.56], and sleeping less than 7 hours per night [OR. 2.02: 95% CL 1.11-3.67] were associated with minor psychiatric disorders. This group of variables determined a cumulative risk ratio of 5.47 [95% CI. 2.87-10.41] for the main outcome.
