高海拔地区塔吉克族中学生睡眠与非自杀性自伤行为的关联

  目的  分析高海拔地区塔吉克族中学生睡眠状况与非自杀性自伤行为(non-suicidal self-injury, NSSI)的关联，为改善中学生身心健康发展状况提供借鉴。  方法  采用分层随机整群抽样方法对新疆塔什库尔干地区1 224名塔吉克族中学生进行睡眠、NSSI、一般人口学状况等方面的调查，采用Logistic回归分析睡眠与NSSI之间的关系。  结果  高海拔地区塔吉克族中学生NSSI检出率为7.92%。有18.71%的学生存在失眠问题，14.62%的学生在过去1周有过至少1次做噩梦。中学生在不同性别、年级、自评身体状况、父亲学历、母亲学历、家庭月收入、吸烟状况、饮酒状况等方面NSSI检出率相比较，差异均有统计学意义(χ2值分别为6.45，19.12，13.83，12.39，8.32，11.45，17.31，9.72，P值均<0.05)。Logistic回归分析显示，上学日睡眠时间≥9 h/d与NSSI存在负相关(OR=0.62)；周末睡眠时间<5 h/d(OR=1.81)、5~<7 h/d(OR=1.45)，失眠(OR=1.33)、做噩梦(OR=1.64~3.27)与NSSI呈正相关(P值均<0.05)。  方法  塔吉克族中学生睡眠时间不足，失眠和做噩梦是非自杀性自伤行为的影响因素。应加强对高海拔地区塔吉克族中学生的睡眠干预，促进身心健康发展。

Relationship between sleep and non-suicidal self-injury behaviors of Tajik middle school students in high altitude areas

  Objective  To analyze the relationship between sleep and non-suicidal self-injury (NSSI) behaviors of Tajik middle school students in high altitude areas, and to provide references for physical and mental health promotion in middle school students.  Methods  The stratified random cluster sampling method was used to select 1 224 Tajik middle school students in the Taxkorgan area of Xinjiang as participants. Sleep, NSSI, general demographic were investigated, and Logistic regression analysis was used to analyze the relationship between sleep and NSSI.  Results  The detection rate of NSSI among Tajik middle school students in high altitude areas was 7.92%. About 18.71% of the students had insomnia problems and 14.62% of students had nightmares at least once in the past week. The detection rates of NSSI differed in gender, grades, physical conditions, father's education, mother's education, family monthly income, smoking status, and drinking status (χ2=6.45, 19.12, 13.83, 12.39, 8.32, 11.45, 17.31, 9.72, respectively, all P<0.05). Logistic regression analysis showed that sleep time ≥9 h/d on school days was negatively correlated with NSSI(OR=0.62); weekend sleep time <5 h/d(OR=1.81), weekend sleep time 5-7 h/d(OR=1.45), insomnia(OR=1.33), nightmares(OR=1.64-3.27) were positively correlated with NSSI(P<0.05).  Conclusion  Insufficient sleep time, insomnia and nightmares are the influencing factors of non-suicidal self-injury behavior in Tajik middle school students. Sleep intervention for Tajik middle school students in high altitude areas should be strengthened to promote physical and mental health.
