Chronotype and Problem Drinking in Medical Students

Objectives ： The aim of this study is to investigate the relationships between chronotype and alcohol use in young adult. Methods ： A total of 197 medical students (age range : 18-25 years, female : 34.5%) participated in this study voluntarily. Each participant completed a self-administered questionnaire that included demographics, plus the Morningness-Eveningness Questionnaire (MEQ), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Barratt Impulsiveness Scale (BIS), Pittsburgh Sleep Quality Index (PSQI), and Alcohol Use Disor-ders Identification Test (AUDIT). Results ： Sixty-one (30.96%) were problem drinkers, with men making up a higher percent-age of problem drinkers (p＜0.001). PD obtained a higher total score on the MEQ (p＜0.01). Evening types reported significant-ly greater levels of problem drinking and worse sleep quality (p ＜0.05). Multiple regression analysis revealed that MEQ was correlated with AUDIT after controlling for sex, age, BDI, STAI, BIS, and PSQI (p＜0.001). Conclusion : Our findings suggest a direct association between problem drinking and eveningness.
