南京市鼓楼区高中学生睡眠状况及其与血压的关系分析

目的 了解南京市鼓楼区高中学生睡眠质量状况及其与血压之间的关系,为改善本区青少年睡眠质量及血压控制提供支持。方法 在南京市鼓楼区以班级为单位随机整群抽取6所高中学校54个班级的2 462名高中学生,对其进行匹兹堡睡眠质量指数量表( PSQI)调查以及身高、体重和血压的测试。结果 青少年睡眠质量差的人数检出率为37.12%。不同年龄青少年间收缩压和舒张压均存在统计学差异(F = 10.12、5.75,P＜0.01)。多元线性回归分析显示,睡眠质量与青少年的收缩压(β = 2.76,P＜0.01)、舒张压(β = 0.76,P＜0.01)存在关联,睡眠质量越差其收缩压和舒张压则越高。结论 青少年睡眠质量与血压之间存在关联,睡眠质量的提高将可能对青少年血压控制起到积极帮助。

Analysis of sleep status and blood pressure of high school students in Gulou district in Nanjing

The aim of this study was to understand the sleep quality status of high school students in Gulou district of Nanjing and its relationship with blood pressure, and thus to provide support for improving the quality of sleep and blood pressure control among adolescents in this area. Methods A total of 2462 high school students from 54 high schools in Gulou district of Nanjing were randomly selected from the class to conduct a Pittsburgh Sleep Quality Index(PSQI) survey and height, weight and blood pressure tests. Results The detection rate of poor sleep quality among adolescents was 37.12%.There were statistical differences in systolic and diastolic blood pressure among adolescents of different ages(F=10.12, 5.75,P<0.01). Multiple linear regression analysis showed that sleep quality was associated with systolic blood pressure(β=2.76, P<0.01) and diastolic blood pressure(β=0.76, P<0.01). The worse the sleep quality, the higher the systolic and diastolic blood pressure. Conclusion There was a correlation between adolescent sleep quality and blood pressure. Improvement of sleep quality might play a positive role in adolescent blood pressure control.
