目的了解维吾尔族初中学生睡眠质量与其血压之间的关系,为促进维吾尔族青少年健康成长提供科学依据。方法对随机整群抽取的新疆喀什地区941名维吾尔族初中生测试身高、体重、血压,并采用匹兹堡睡眠质量指数量表(PSQI)进行问卷调查。结果维吾尔族初中生的收缩压随着年龄的增长呈上升趋势,由12岁时的102.81 mm Hg上升到15岁时的106.24 mm Hg。12~15岁各年龄段学生收缩压与舒张压差异均有统计学意义(F值分别为7.71,7.14,P值均<0.05)。维吾尔族初中生收缩压或舒张压在P95及以上者53人,占5.14%。无睡眠障碍组学生的血压低于有睡眠障碍组学生的血压,并且收缩压差异有统计学意义(t=-2.77,P<0.01)。在未调整和调整年龄、性别、体质量指数、是否吃咸、高血压家族史等因素的多元线性回归模型中,睡眠质量均和收缩压、舒张压有统计学联系(β值分别为4.41,3.45,P值均<0.01)。结论维吾尔族初中生的血压与睡眠质量存在相关。改善学生睡眠质量将有助于高血压的预防。
Objective To understand the relationship between sleep quality and blood pressure of Uighur junior high school students and to provide a scientific basis for promoting the healthy growth of Uighur adolescents. Methods A total of 941 Uighur junior high school students from Kashgar region in Xinjiang were tested for height, weight and blood pressure using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Results The Uygur junior high school students’ systolic blood pressure increased with the increase of age from 102.81 mm Hg at age 12 to 106.24 mm Hg at 15 years old. There were significant differences in systolic and diastolic blood pressures between 12 and 15 years old (F = 7.71 and 7.14, P <0.05 respectively). Uighur junior high school students systolic blood pressure or diastolic blood pressure in P95 and above 53, accounting for 5.14%. The blood pressure of students without sleep disturbance group was lower than that of students with sleep disturbance, and the difference of systolic pressure was statistically significant (t = -2.77, P <0.01). In the multivariate linear regression model without adjusting and adjusting the factors such as age, sex, body mass index, whether to eat salty, family history of hypertension and so on, the sleep quality had statistical relationship with systolic pressure and diastolic pressure (β values were 4.41, 3.45, P <0.01). Conclusion There is a correlation between the blood pressure and the quality of sleep among Uighur junior high school students. Improving the quality of student sleep will help to prevent high blood pressure.
