Abstract: Background　Insomnia is often found in older people with hypertension，which may be due to psychological，physiological or medication.，Hypertension patients are more prone to insomnia，which in turn aggravates hypertension.Increasing evidence shows that the patients with higher adherence to DASH diet have lower physical and mental health risk，so DASH diet may be an option for reducing the risk of insomnia in patients with hypertension.Objective　To assess the effectiveness of DASH diet on the risk of insomnia among older patients with hypertension.Methods　From April to July 2020，stratified，random sampling was used to select community-dwelling older adults（≥60 years） Taiyuan to attend a questionnaire survey，which consists of the flowing parts：general demographic characteristics（gender，age，marital status，hukou type），socioeconomic status（education duration，annual household income per capita），physiological characteristics（height，weight and hypertension stage），lifestyle characteristics〔smoking prevalence，alcohol consumption frequency，bedtime screen time and physical activity，evaluated by International Physical Activity Questionnaire-Short Form（IPAQ-S）〕，DASH diet（evaluated by the Chinese Revised DASH score scale），and insomnia〔evaluated by Taiwan version of Athens Insomnia Scale（AIS-T）〕.We divided patients into insomnia and non-insomnia groups according to insomnia prevalence.Binary logistic regression analysis and hierarchical linear regression analysis were used to explore the relationship between DASH diet and insomnia.Results　A total of 300 cases attended the survey，280 of them（93.3%） who handed in responsive questionnaires were finally included.Those with insomnia（n=116） had greater BMI ，alcohol consumption frequency and lower mean DASH diet score than those without（n=164）（P<0.05）.After controlling for age，alcohol consumption，bedtime screen time and BMI，Binary Logistic regression analysis demonstrated that insomnia was positively correlated with DASH diet score〔OR=0.86，95%CI（0.79，0.93）〕.After controlling for the covariates，the hierarchical linear regression with intergroup statistically significantly different variables incorporated revealed that the individual's DASH diet score was associated with the functioning during the day （in the AIS-T）（β=-0.41，P=0.04）.Conclusion　Insomnia may be associated with DASH diet among elderly patients with hypertension.

摘要： 背景　老年高血压患者由于心理、生理、用药等原因，常伴有失眠症。罹患高血压会增加罹患失眠症的风险，同时罹患失眠症又会引起高血压的病情恶化。越来越多的证据表明DASH饮食模式依从性较高者的生理和心理健康风险较低，DASH饮食模式可能会成为降低高血压患者罹患失眠症风险的一种方式。目的　DASH饮食模式与老年高血压患者失眠的关系。方法　采用分层随机抽样的方法于2020年4—7月，在太原市社区内进行了问卷调查，招募60岁及以上高血压患者，收集患者一般人口学特征（性别、年龄、婚姻类型、户籍类型）、社会经济地位特征（受教育时长、家庭人均年收入）、生理特征（身高、体质量和高血压级别）、生活方式特征（吸烟与否、饮酒频率、睡前屏幕使用时长和体力活动），体力活动采用国际体力活动量表的简短版（IPAQ-S）评价，DASH饮食模式评价使用中文修订版DASH得分量表，失眠情况评估使用台湾版阿森斯失眠量表（AIS-T）。根据患者是否发生失眠症分为失眠症组和无失眠症组。并通过二元Logistic回归分析和分层多元线性回归分析探讨DASH饮食模式及失眠症的关系。结果　共发放调查问卷300份，回收有效问卷280份，有效回收率为93.3%。280例患者中有失眠症116例（失眠症组），无失眠症164例（无失眠症组）。失眠症组BMI高于无失眠症组，饮酒频率、DASH得分低于无失眠症组（P<0.05）。控制了年龄、饮酒、睡前屏幕使用时长和BMI后，二元Logistic回归分析结果显示失眠症与DASH得分呈正相关〔OR=0.86，95%CI（0.79，0.93）〕。将差异性分析结果有意义的特征纳入分层多元线性回归分析中，控制了协变量后，DASH得分与失眠症的“日间功能”组分相关（β=-0.41，P=0.04）。结论　老年高血压患者失眠症与DASH饮食模式相关。
