Outline of Final Research Achievements

This study was conducted to examine the impact of sleep-wake problems on health-related quality of life of Japanese nursing college students. This cross-sectional study was conducted on 150 third and fourth-year nursing college students in Japan. Insomnia severity was assessed using the ISI and health-related quality of life using the SF-8 questionnaire. The total sleep time (TST) was divided into 3 groups: <6hr, 6-7hr, and ≧7hr. The total ISI score was divided into 2 groups: ≧ 8 points and <8 points. Logistic regression analysis was performed to evaluate sleep-wake problems related to decline in mental health.
The median mental health indicated in the SF-8 questionnaire was divided into two groups, and the factors causing decline in mental health were investigated. The odds ratios (95%Cl) for adjusted ISI 8 and TST on weekdays <6hr was 6.51 (2.96-14.30) and 3.38 (1.40-8.17). Mental health status was significantly lower when ISI≧8 and even lower when TST<6 hr.

Academic Significance and Societal Importance of the Research Achievements

看護大学生では、不眠と短時間睡眠の併存が精神的健康度の低下と最も関連していた。不眠症状に短時間睡眠を伴う場合は、学業だけでなく、看護師就業後の交代勤務生活に影響する恐れもある。そのため、学生のうちから自身の睡眠状況を自覚できるよう、睡眠衛生に関する教育や、不眠症に対する認知行動療法を含めたアプローチなど、スクリーニング結果に基づく適切な睡眠・覚醒相の理解を促し、適切に対処することが求められている。
