Study On Sleep Quality And Its Associated Factors Among Young-and Middle-aged Hospitalized Patients With Hypertension

Objective: To understand the sleep quality of young-and middle-aged hospitalized patients with hypertension,and to explore the influence of sociodemographic characteristics,living and behavioral habits,hypertension-related characteristics and comorbidities,and psychological status on sleep quality of young-and middle-aged hospitalized patients with hypertension,and to further determine factors affecting sleep quality among young-and middle-aged hospitalized patients with hypertension.Methods: Using a cross-sectional study design,eligible young-and middle-aged hospitalized patients with hypertension who were admitted to the Cardiology Department of a tertiary hospital in Changsha City,Hunan Province from June 2020 to June 2021 were continuously selected.Information on sociodemographic characteristics,living and behavioral habits,hypertension-related characteristics and comorbidities were collected by issuing self-administered questionnaires.The Pittsburgh sleep quality index(PSQI),Zung’s Self-Rating Anxiety Scale(SAS),and Zung’s Self-Rating Depression Scale(SDS)were used to evaluate the sleep quality,anxiety,and depression of the subjects.Chi-square test was used to compare the difference of enumeration data between sleep disorder group and non-sleep disorder group,Pearson correlation was used to analyze the correlation between anxiety,depression and sleep quality,and unconditional multivariate logistic regression analysis was used to determine factors affecting sleep quality among young-and middle-aged hospitalized patients with hypertension.Results:(1)A total of 672 questionnaires were distributed in this study,616 valid questionnaires were recovered,and the pass rate was91.7%(616/672).The mean age of the 616 subjects was 46.73±12.15 years,370(58.4%)were male,555(90.1%)were Han,105(17.0%)had junior high school education and below,and 566(91.9%)had spouses,126(20.5%)with average monthly household income ≤ 3,000 yuan,461(74.8%)with working status,44(7.1%)living alone,and 122(19.8%)with new farming close,250(40.6%)were overweight or obese.(2)According to the criterion for the existence of sleep disorders of PSQI>7 points,among the 616 research subjects,296 had sleep disorders,and the positive rate of sleep disorders was 48.1%(292/616).(3)Pearson correlation analysis showed that the PSQI scale score and SAS scale score(r=0.455,P<0.001),PSQI scale score and SDS scale score(r=0.387,P<0.001),SAS scale score and SDS scale score(r=0.789,P<0.001)were all positively correlated.(4)Multivariate logistic regression analysis showed that physical exercise(OR=0.52,95%CI: 0.31-0.78,P=0.001)and nap habit(OR=0.70,95%CI: 0.52-0.89,P=0.013)were protective factors of sleep quality among young-and middle-aged hospitalized patients with hypertension,female(OR=1.41,95%CI: 1.13-3.69,P=0.023),hypertension grade II(OR=1.43,95%CI: 1.19-5.12,P =0.035)and grade III(OR=2.12,95%CI:1.67-7.15,P<0.001),number of comorbidities 2-3(OR=1.53,95%CI:1.12-4.53,P=0.021)and ≥ 4(OR=2.23,95%CI: 1.57-7.55,P<0.001),anxiety(OR=2.65,95%CI: 1.52-6.77,P<0.001),depression(OR=1.42,95%CI: 1.09-2.88,P=0.002)was a risk factor for sleep quality among young-and middle-aged hospitalized patients with hypertension.Conclusions:(1)The positive rate of sleep disorder among young-and middle-aged hospitalized patients with hypertension in the Cardiology Department was 48.1%.(2)Physical exercise and nap habits are associated with sleep disorders among young-and middle-aged hospitalized patients with hypertension;female,high blood pressure grades,a large number of co-morbidities,anxiety and depression are also associated with sleep disorders among young-and middle-aged hospitalized patients with hypertension in the Cardiology Department.
