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 high school students and to provide a scientific basis for reducing and preventing hypertension in children and adolescents. Methods A randomized cluster sampling method was used to investigate Pittsburgh Sleep Quality Index (PSQI) questionnaire and measure the height, weight and blood pressure of 852 middle school students in Weifang City. Results Among the seven components of the PSQI scale, there were significant differences in the blood pressure among junior middle school students (P <0.05), sleep quality, sleep disturbance Systolic blood pressure were statistically significant (P values were <0.05), different difficulty falling asleep between the blood pressure was no significant difference (P> 0.05). Multivariate linear regression model adjusted for age, gender, body mass index and other factors, there was a significant correlation between sleep quality and diastolic blood pressure (β = 2.18) and systolic blood pressure (β = 2.50) in junior high school students (P <0.01). Conclusion Junior high school students blood pressure and sleep quality related. Improve the quality of sleep in junior high school students contribute to the prevention of hypertension in children and adolescents.
