初中生睡眠质量现况及其与血压的关系

Relationship between sleep quality and blood pressure in junior school students

目的探讨初中生睡眠质量与血压的关系,为减少和预防儿童青少年高血压提供科学依据。方法采用随机整群抽样方法,对潍坊市852名初中生进行匹兹堡睡眠质量指数量表(PSQI)问卷调查,并测量初中生的身高、体重和血压。结果 PSQI量表的7个成分中,不同主观睡眠质量、睡眠时间、催眠药物和日间功能障碍组初中生间血压差异均有统计学意义(P值均<0.05),睡眠效率和睡眠障碍与收缩压均有统计学意义(P值均<0.05),不同入睡难易组间血压差异无统计学意义(P>0.05)。多元线性回归模型调整了年龄、性别、体质量指数等因素后,初中生睡眠质量与舒张压(β=2.18)、收缩压(β=2.50)存在统计学关联(P值均<0.01)。结论初中生血压与睡眠质量相关。改善初中生睡眠质量有助于儿童青少年高血压的预防。

Objective To explore the relationship between sleep quality and blood pressure in junior school students,and to provide scientific evidence for the prevention.Methods By cluster sampling,852 junior school students were investigated with Pittsburgh Sleep Quality Index（PSQI） and their height,weight and blood pressure were examined.Results The components of subjective sleep quality,sleep duration,daytime dysfunction and use of sleep medication were related to blood pressure.Both sleep efficiency and sleep disturbance were related to systolic pressure.The association between sleep latency and blood pressure was not significant.Sleep quality of junior school students was related to diastolic and systolic pressure in multiple linear regression model adjusted for confoundings.Conclusion Sleep quality is related to blood pressure in junior school students.The improving of sleep quality will help to prevent from hypertension incident among children and adolescents.
