睡眠时间和睡眠质量对我国中老年人高血压发病率的影响

Effect of sleep duration and quality on hypertension incidence in Chinese middle-aged and elderly people

目的了解我国中老年人高血压发病情况,并探讨睡眠时间和睡眠质量与我国中老年人高血压发病率之间的关系。方法运用2011年和2015年中国健康与养老追踪调查数据(China health and retirement longitudinal study,CHARLS),共纳入45岁及以上中老年6 047人。睡眠时间被定义为过去1个月平均每晚的实际睡眠时间,睡眠质量应用自编问卷进行评估。睡眠时间和睡眠质量对高血压发病率的影响采用多因素Logistic回归模型分析。结果经过4年随访,1 151人发生了高血压,累积发病率为19.03%。多因素Logistic回归模型分析结果显示,单纯睡眠时间异常或睡眠质量不佳均对高血压发病率无影响,在性别、年龄的亚组分析中结果保持不变。进一步研究不同组合的睡眠时间和睡眠质量与高血压的关系,结果显示睡眠时间和睡眠质量与高血压的联合效应差异均无统计学意义(均有P>0.05)。结论无充分证据显示睡眠时间和睡眠质量与我国中老年高血压发病率有关且年龄、性别对该相关性无影响。

Objective To investigate the incidence of hypertension among Chinese middle-aged and elderly people,and to explore the association of sleep duration and sleep quality with the incidence of hypertension.Methods Our data were collected from the 2011 and 2015 China health and retirement longitudinal study(CHARLS),a total of 6047 middle-aged and elderly individuals aged 45 years and over were included in this study,sleep duration were measured as self-reported average sleep time in the past month.Sleep quality was evaluated using the self-made questionnaire.The association of sleep duration and sleep quality with the incidence of hypertension was analyzed using multivariate logistic regression analysis.Results After four years of follow-up,1151 peoples developed hypertension,and the cumulative incidence rate was 19.03%.Logistic regression analysis showed that abnormal sleep time or poor sleep quality had no effect on the incidence of hypertension.The results remained unchanged in the subgroup analysis of sex and age.Further investigation of the association of different combinations of sleep duration and quality in relation to hypertension indicated that the combined effect of sleep time and sleep quality on hypertension was not statistically significant(all P>0.05).Conclusion There is no sufficient evidence supporting correlation between sleep time and sleep quality with the incidence of hypertension in the middle-aged and the elderly in China,and age and sex had no effect on the correlation.
