説明

本研究の目的は，女子総合大学学生の睡眠の特徴と生活習慣との関連について検討し，睡眠健康教育に必要な基礎的資料を得ることである。女子総合大学の学生1,037名，平均年齢20.3歳を対象とした質問紙調査を行った。調査内容は，睡眠の量（睡眠時間，就寝・起床時刻），睡眠の質（睡眠効率，熟眠感），睡眠のリズム（就寝・起床時刻の不規則頻度），日中の眠気と精神的健康状態，生活習慣，自己管理スキルである。対象者は，全体的に睡眠時間が短く睡眠の質が悪い者は4 割であった。睡眠の量，質，リズムによるクラスタ分析から不規則不足群168名，規則的短時間群648名，睡眠良好群221名の3 群に分類された。不規則不足群は，睡眠の量・質が最も悪くリズムの乱れと睡眠位相後退を認め，精神的健康状態も悪かった。日中の眠気や授業中の居眠り頻度に群間差はなかった。睡眠健康のための生活習慣実践を3 群で比較すると，規則的短時間群の生活習慣実践数が最も多く自己管理スキルが有意に高かった。不規則不足群に対する睡眠健康教育では，不規則な生活リズムの改善に着目することで睡眠状態が改善する可能性が示唆された。The purpose of this study was to acquire basic reference materials required for sleep health education regarding the correlation between sleeping habits and lifestyles of female university students through a questionnaire survey.The subjects consisted of 1,037 female university students having an average age of 20.3 years. Survey questions related to the amount of sleep（sleep time, bedtime, wakeup time）, quality of sleep（sleepefficiency, depth of sleep）, sleep rhythm（frequency of irregular bedtimes or wakeup times）, daytime drowsiness and mental health, lifestyle, and self-management skills.The subjects exhibited short sleep times and poor sleep quality overall. The subjects were divided into three groups consisting of an irregular, insufficient sleep group comprised of 168 subjects, a regular, short sleep time group comprised of 648 subjects and a proper sleep group comprised of 221 subjects based on a cluster analysis using the amount of sleep, sleep quality and rhythms of the subjects as standardized variables. Poor sleep quantity and quality as well as disturbances in sleep rhythm were observed in the irregular, insufficient sleep group in particular and these subjects were characterized by delayed sleep phase and poor mental health. There were no differences in daytime drowsiness or dozing off in class between the groups.When lifestyle practices for sleep health were compared among the three groups, the number of lifestyle practices in the regular, short sleep time group was the largest and self-management skills were significantly higher. The regular, short sleep time group led lifestyles that were more aware of entrainment factors in comparison with the irregular, insufficient sleep group. Sleep health education targeted at the irregular, insufficient sleep group suggested the possibility of being able to expect improvement of sleep state by making efforts towards improvement irregular lifestyle.
