Self-Reported Sleep Quality, Duration, and Health-Related Quality of Life in Older Chinese: Evidence From a Rural Town in Suzhou, China

Abstract

Study Objectives: To determine the associations of self-reported sleep quality and duration with health-related quality of life (HRQOL) in older Chinese. Methods: We analyzed community-based cross-sectional data of 5,539 individuals aged 60 years and older in the Weitang Geriatric Disease Study. Information of sleep quality and duration were self-reported through participants' responses to predefined questions; HRQOL data were collected by using the European Quality of Life-5 Dimensions (EQ-5D). We estimated the associations of sleep quality and duration with the EQ-5D index and visual analog scale (VAS) scores using linear regression models. The associations between sleep quality and duration and EQ-5D-detected health problems were modeled using logistic regression. Results: In multiple linear models adjusting sociodemographic factors, health conditions, and lifestyle habits, both EQ-5D index and VAS scores declined with deterioration of sleep quality. The coefficients for poor and intermediate sleep quality were −0.053 (95% confidence interval [CI]:−0.065, −0.042) and −0.022 (95% CI: −0.030, −0.013), respectively, in relation to EQ-5D index score. They were −5.2 (95% CI: −6.7, −2.4) and − 3.8 (95% CI: −4.9, −2.7) in modeling the EQ-5D VAS score. HRQOL declined as sleep duration decreased below 7.01 hours or exceeded 8.01 hours, though most of the associations did not reach statistical significance. In multiple logistic models, poor sleep quality was associated with problems of mobility, pain/discomfort, and anxiety/ depression; short sleep duration was associated with mobility problems. Conclusions: Poor sleep quality and extreme sleep durations appeared to be negatively associated with HRQOL in older Chinese adults.

Association of sleep duration with sleep disturbances, quality of life, and sociodemographic factors in general hospital outpatients

“…7 The association between sleep patterns and QOL is strongly influenced by ethnic and sociocultural factors, and therefore it is important to examine their relationship in different sociocultural contexts. 8 Several studies have examined the association between sleep duration and QOL in both general 9,10 and specific populations in China, including schizophrenia, 11 but the findings have been inconsistent. For example, Chiu et al 9 found that short sleep duration was associated with lower QOL, while others 11 did not confirm this finding.…”

Prevalence and associated factors of poor sleep quality among Chinese older adults living in a rural area: a population-based study

“…Evidence is emerging that the socio-demographic and lifestyle factors may play a role in sleep disorders among older adults. For instance, female gender, low education, divorce and widowhood, living alone, inadequate fruit intake, drinking tea, alcohol consumption, caffeine, use of certain medications, poor mental health, and physical inactivity have been reported to be associated with sleep disturbance [5,6,[11][12][13][14][15][16][17][18][19][20]. In addition, poor sleep quality or sleep disorders in old people are associated with highly prevalent chronic health conditions, such as hypertension [21], type 2 diabetes [22], cardiovascular disease [23], stroke [24], depression [25], and cognitive impairment [26].…”

Dose-response association of sleep quality with anxiety symptoms in Chinese rural population: the Henan Rural Cohort

“…Furthermore, the PSQI score was dichotomized to examine the association between poor sleep quality and anxiety symptoms with good sleep quality as reference group by performing logistic regression models. In the fully adjusted model, we included age, gender , physical activity, marital status, smoking status, drinking status, educational levels, average monthly income and BMI, night sleep duration and napping duration in the model as the underlying confounder according the previous studies [29,30]. Additionally, strati ed analyses were conducted by each potential modi er to examined whether poor sleep quality and anxiety symptoms were potentially changed by age, gender, marital status, smoking status, drinking status, average monthly income , physical activity, BMI, snoring, hypertension, type 2 diabetes mellitus(T2MD).…”
