Effect of sleep quality on hypertension patients with dysmnesia

Abstract

Objective To discuss the influence of sleep quality on hypertension patients with dysmnesia.Methods Hypertension patients from Department of Cardiology and Hypertension in Tangshan Gongren Hospital from September to December 2011 were chosen by convenience sampling.Self-designed questionnaire was used to collect their data,Pittshurge sleep Quality Index (PSQI) and the rivermead behavicural memory test second edition (RBMT-Ⅱ) were used to assess their sleep quality and memory function.After assessment,patients with dysmnesia were included in the observation group,and patients with normal memory function were included in the control group.The effect of sleep quality on hypertension patients with dysmnesia was analyzed by logistic regression analysis.Results 60％ hypertension patients with dysmnesia had poor sleep quality,and only 25％ hypertension patients with normal memory function had poor sleep quality.The score of PSQI was much higher in the observation group than in the control group [(10.23 ±4.0) vs (5.88 ±1.60)],and the differences was statistically significant (t =6.293,P ＜0.01).Single factor logistic regression analysis showed that hypertension patients with poor sleep quality had 4 times higher risk of dysmnesia than those who had normal sleep quality (OR =4.059,95％ CI =1.568-10.510).Conclusions Poor sleep quality was a risk factor of dysmnesia to hypertension patients,therefore improving sleep quality in hypertension patients is helpful to ease their decrease of memory function.
