A Study Of Sleep Quality And Related Factors Among The Rural Elderly With Hypertension In Anhui Province

ObjectivesThe purposes of this article were to know awareness, treatment and control forhypertension and sleep quality, figure out the correlation between sleep quality andblood pressure, further to explore the related factors of sleep quality among ruralelderly with hypertension in Anhui province. Our aim is to provide evidences for futuremeasures which focus on improving their sleep quality and better hypertension control.MethodsA total of1597patients with hypertension from4areas aged over60from ruralareas were sampled. Self-designed questionnaire and body measures were investigatedfor general condition, awareness、treatment、control for hypertension. Pittsburgh SleepQuality Index （PSQI） was used to assess sleep quality. EpiData3.1and SPSS13.0were used to statistically descriptive analysis. Spearman correlate, univariate, Binaryand Multivariate Logistic Regression were used to explore the correlation betweensleep quality and blood press and to analyze the related factors of poor sleep.ResultsAmong1597rural elderly with hypertension in Anhui province, the percent ofnormal blood pressure is18.48%, the precent of prehypertension, stage1, stage2,stage3is12.66%,40.23%,21.55%,7.08%;34.46%is ISH （isolated systolichypertension）, about72.64%knew themselves had hypertension,32.31%patients tookantihypertensive drugs,31.14%patients had a good control on blood pressure. Among 1597cases, the average PSQI score were7.31±3.92,765cases（47.84%） had poorsleep quality and832cases（52.16%）had good sleep quality. The average PSQI scoreis8.01±3.94in female, higher than in male（6.62±3.77）（t=-7.201, P=0.000）.Newhypertension cases had higher PSQI score than cases with hypertension history（t=5.377, P=0.001）. Cases with antihypertensive drugs had higher PSQI score thancases without antihypertensive drugs （t=3.472，P=0.001）. Cases with abnormal bloodpressure control had higher PSQI score than those with normal control （t=5.348，P=0.000）. PSQI score were significantly different between the subjects with differentblood pressure levels（F=11.799，P=0.000）. Correlate results between PSQI score andSBP、DBP show, there was a correlation between sleep duration, sleep disturbance, daytime dysfunction, PSQI and SBP（P<0.01）. However only sleep disturbance correlatedwith DBP （P<0.01）. Multivariate Logistic Regression results showed cases withfemale, age, living alone, farmer, coronary heart disease history, stomach diseasehistory, bronchitis history, using drug treatment, hypertension with stage1and3, ISHhad a poorer sleep quality than others.ConclusionOur data showed that rural elderly with hypertension in Anhui Province had apoor sleep quality, the related factors for sleep quality were sex, age, livingarrangement, occupation, coronary heart disease history, stomach disease history,bronchitis history, blood pressure levels, drug treatment, ISH. These results remind ussleep is important to control blood pressure and how to improve sleep quality, furtherto enhance their quality of life.
