Effects of chronotype and environmental factors upon sleep and mental health in Japanese students aged 18-40 yrs
Original language description
Integrated questionnaire was administered to 4142 university and medical training schools students (2137 females, 2005 males; answer rate: 94.4%) 18-40 years. The survey was carried out between May and October, 2004?2013. Questionnaire consisted of assessment of diurnal type, questions on sleep habits, mental health (upset emotionally, irritated, angered by small triggers, and suppressed), frequency of watching TV at night, use of mobile phone and playing TV games between 21pm and 3am, questions on lighting conditions during the daytime and night. Sleep length in evening-type students (E-type; diurnal-type scores = 7?12) was shorter than in intermediate-types (I-type; diurnal-type scale (DTS) = 13?16) and morning-types (M-type; DTS = 17?28) on weekdays(p < 0.001), whereas sleep length in evening-types was shorter than intermediate- and morning-type students at weekends (p < 0.001). Mental health index scores of the E-type students were significantly lower than those of I-type and M-ty
