Decrease in Sleep Duration and Poor Sleep Quality over Time Is Associated with an Increased Risk of Incident Non-Alcoholic Fatty Liver Disease

The impact of changes in sleep duration and sleep quality over time on the risk of non-alcoholic fatty liver disease (NAFLD) is not known. We investigated whether changes in sleep duration and in sleep quality between baseline and follow-up are associated with the risk of developing incident NAFLD. The cohort study included 86,530 Korean adults without NAFLD and with a low fibrosis score at baseline. The median follow-up was 3.6 years. Sleep duration and quality were assessed using the Pittsburgh Sleep Quality Index. Hepatic steatosis (HS) and liver fibrosis were assessed using ultrasonography and the fibrosis-4 index (FIB-4). Cox proportional hazard models were used to determine hazard ratios (HRs) and 95% confidence intervals (Cis). A total of 12,127 subjects with incident HS and 559 with incident HS plus intermediate/high FIB-4 was identified. Comparing the decrease in sleep duration of >1 h, with stable sleep duration, the multivariate-adjusted HR (95% CIs) for incident HS was 1.24 (1.15–1.35). The corresponding HRs for incident HS plus intermediate/high FIB-4 was 1.58 (1.10–2.29). Comparing persistently poor sleep quality with persistently good sleep quality, the multivariate-adjusted HR for incident HS was 1.13 (95% CI, 1.05–1.20). A decrease in sleep duration or poor sleep quality over time was associated with an increased risk of incident NAFLD, underscoring an important potential role for good sleep in preventing NAFLD risk.

Abstract Background : To assess the association of sleep duration and quality with the risk of preterm birth. Methods : Relevant studies were retrieved from the PubMed and Web of Science databases up to September 30, 2018. The reference lists of the retrieved articles were reviewed. Random effects models were applied to estimate summarized relative risks (RRs) and 95% confidence intervals (CIs). Results : Ten identified studies (nine cohort studies and one case-controlled study) examined the associations of sleep duration and quality with the risk of preterm birth. As compared with women with the longest sleep duration, the summary RR was 1.23 (95% CI = 1.01–1.50) for women with the shortest sleep duration, with moderate between-study heterogeneity ( I 2 = 57.4%). Additionally, as compared with women with good sleep quality, the summary RR was 1.54 (95% CI = 1.18–2.01) for women with poor sleep quality (Pittsburgh Sleep Quality Index > 5), with high between-study heterogeneity ( I 2 = 76.7%). Funnel plots as well as the Egger’s and Begg’s tests revealed no evidence of publication bias. Conclusions : This systematic review and meta-analysis revealed that short sleep duration and poor sleep quality may be associated with an increased risk of preterm birth. Further subgroup analyses are warranted to test the robustness of these findings as well as to identify potential sources of heterogeneity.

Stratified Analysis

Objective The aim of this study is to explore sleep status and hypertension among oil workers in Xinjiang, China. It may provide new ideas and basis for the precise prevention and treatment of hypertension in occupational population. Methods Sleep status and hypertension were investigated in 3,040 workers by a multi-stage cluster sampling method in six oil field bases in Karamay City, Xinjiang. The Pittsburgh Sleep Quality Index was used to evaluate the sleep status of workers. Logistic regression was used to analyze the relationship between sleep duration and sleep quality, and hypertension. Stratified analysis was also performed. Results Our results show: 1. Insufficient sleep duration (OR = 1.51, 95% CI [1.19–1.90]) and poor sleep quality (OR = 1.78, 95% CI [1.33–2.38] were positively associated with hypertension. 2. Stratified analysis indicated insufficient sleep duration was associated with increased risk of hypertension in females (OR = 1.54, 95% CI [1.16–2.04]) than males (OR = 1.49, 95% CI [1.00–2.23]), and the risk of hypertension in the group <30 years old (OR = 9.03, 95% CI [2.32–35.15]) was higher than that in the group of 30–45 years old (OR = 1.59, 95% CI [1.14–2.20]). However, in the group > 45 years old, sleeping > 8 h was associated with increased risk of hypertension (OR = 3.36, 95% CI [1.42–7.91]). Oil workers doing shift work had a higher risk of hypertension (OR = 1.55, 95% CI [1.16–2.07]) to no shift work (OR = 1.48, 95% CI [1.02–2.15]). The risk of hypertension in the group with < 10 years of service (OR = 4.08, 95% CI [1.92–8.83]) was higher than that in the group with length of service of 10–20 years (OR = 2.79, 95% CI [1.59–4.86]). Poor sleep quality was associated with risk for hypertension in females (OR = 1.78, 95% CI [1.26–2.49]), those doing shift work (OR = 1.70, 95% CI [1.17–2.47]), those with length of service of > 20 years (OR = 1.64, 95% CI [1.18–2.27]). The risk of hypertension in the group 30–45 years old is higher than that in the group > 45 years old (OR 30–45 years old = 1.71, 95% CI [1.10–2.66]; OR > 45 years old = 1.60, 95% CI [1.09–2.34]). Conclusion Insufficient sleep duration and poor sleep quality are the potential factors affecting hypertension in Xinjiang oil workers.

Short sleep duration or poor sleep quality has been associated with an increased risk of obesity. Although the underlying mechanism remains unclear, one proposed pathway is poor diet quality. This cross-sectional study investigated whether diet quality modifies the association between sleep status and obesity in Korean adults. We used the baseline data and samples of 737 men and 428 women (n = 1165) aged 19–64, who participated in the prospective Ewha–Boramae cohort study. Sleep duration was dichotomized into ≥7 h (adequate) and <7 h (insufficient). Pittsburgh Sleep Quality Index (PSQI) values, reflecting sleep quality, were dichotomized into >5 (poor quality) and ≤5 (good quality). Diet quality was evaluated by the Recommended Food Score (RFS). Obesity was associated with higher rates of insufficient sleep and poor sleep quality in women, but not in men. After adjustment for covariates, women with poor sleep quality had a higher risk of obesity than women with good sleep quality (OR = 2.198; 95% CI = 1.027–4.704); this association occurred only in the group with RFS ≤ median score. Our findings support a significant association between sleep quality and obesity, and this association has been potentially modified by dietary quality in women.

This study examined relationships between self-perceived sleep quality and resilience among 116 dance students (Mean age = 21.6 years; SD = 4.348). who self-reported sleep quality with the Pittsburgh Sleep Quality Index (PSQI) and personal resilience with the Resilience Scale (RS). Most participants (59.5%) reported poor sleep quality on the PSQI, with 62.9% of the women and 42.1% of the men ( p = .092) scoring higher than five points on this instrument. On the RS, a large majority of the participants (75%) obtained scores less than 147, indicating low resilience, with no significant gender differences observed. Those reporting poor sleep quality (PSQI scores > 5) obtained lower resilience scores (RS < 147) than those reporting good sleep quality (PSQI scores ≤ 5; p = .025), and participants with poorer sleep quality were at higher risk of low resilience (Odds Ratio = 3.273) relative to those with good sleep quality ( p = .006). Those with shorter duration sleep (claiming they slept <7 hours/night) were also at higher risk for low resilience (Odds Ratio = 3.266), relative to those with longer duration sleep (>7 hours/night). These findings can help students and dance professionals improve their performance and face pressures inherent in dance practice. Follow-up research should verify these findings in varied populations with objective sleep measures and observational data from multiple respondents.

Background: Previous studies have demonstrated a link between both sleep quantity and quality and an increased risk of CVD, stroke, and diabetes. However only a few population-based studies have information on the association of sleep quantity and quality and subclinical atherosclerosis as measured by coronary artery calcium (CAC) and ankle brachial index (ABI) -- a marker for peripheral arterial disease. Methods: CHAS data were used to investigate cross-sectional associations of short sleep duration and poor sleep quality assessed by the Pittsburgh Sleep Quality Index (PSQI) (see Table Footnote for definition of poor sleep quality and quantity) and prevalence of having CAC (score > 0) or low ABI (<0.99). CAC, assessed by multi-detector computed tomography, was quantified by the Agatston’s method. ABI was calculated as the ratio of Doppler recorded systolic pressures in the lower and upper extremities (ABI >1.4 was excluded). Results: The study sample consists of 1,005 men and 390 women ages 65-84 (mean age 71) in 2007-10; 9% were African American. There are no differences in CAC prevalence among participants with or without short sleep duration (11.2% vs. 11.0%). For low ABI, these figures are 20% and10.8%, respectively. With multiple adjustments (see Table Footnote), there are no significant associations of short sleep duration or poor sleep total score with prevalent CAC. However, participants with short sleep duration are more likely to have low ABI, i.e., the odds (95% confidence interval) of having ABI <0.99 with sleep duration of <6hrs was almost two fold (1.02-3.13) compared to others (see Table). Conclusion: In older age, shorter sleep duration is associated with peripheral vascular disease. Sleep may represent a modifiable risk factor for CVD.

Background: Sleep disturbance is associated with multiple adverse cardiovascular-related health outcomes. Little is known about the relationship between psychological well-being, an independent modifiable risk factor for cardiovascular disease, and sleep disruptions. This study examines cross-sectional and longitudinal associations of optimism with sleep duration and quality. Methods: Data were collected from 3,549 Black and White adults aged 33-45 years who participated in the Coronary Artery Risk Development in Young Adults (CARDIA) study during follow-up years 15 (2000-2001) and 20 (2005-2006). Optimism was assessed in 2000-2001 using the Life-Orientation Test—Revised, with possible scores ranging from 6 (least optimistic) to 30 (most optimistic). Single-item questions on sleep quality and duration in the past month were assessed during 2000-2001 and 2005-2006. Cross-sectional analyses considered optimism and sleep measures at follow-up year 15. Longitudinal analyses considered 5-year incidence of poor sleep quality (fairly/very bad) and duration (short/long sleep) in 2005-2006 by optimism in 2000-2001 (participants with poor sleep quality and duration in 2000-2001 were excluded). Results: Among 3,549 participants (56% female, 46% Black) with complete data on optimism in 2000-2001, 15.9% reported fairly/very bad sleep quality. Sleep duration was distributed as follows: short-sleep (47.9%), sufficient sleep (31.6%), and long-sleep (20.5%). In unadjusted and fully adjusted models, a 1-unit higher optimism score was cross-sectionally associated with 11% lower odds of having fairly/very bad sleep quality and 3-5% lower odds of having short-sleep duration (Table 1). Cross-sectional associations were attenuated after adjustment for depressive symptoms (not shown). Incidence of poor sleep quality in 2005-2006 was 7% lower with each unit higher optimism score, after full adjustment. Conclusion: Optimism is associated with lower incidence of poor self-reported sleep quality over a 5-year period.

Aims. It is known that sleep has a major role in the regulation of endocrine functions and glucose metabolism. However, it is not clear whether the sleep pattern is affected at or prior to the onset of diabetes, among those with prediabetes. The purpose of this study was to determine the association of sleep patterns and prediabetes in Qazvin, Iran.Methods. A representative sample of residents of Qazvin was selected by multistage cluster random sampling method in 2011. Plasma glucose level and sleep quality were measured cross-sectionally as well as demographic characteristics. A logistic regression analysis was used to examine the association of sleep status and prediabetes.Results. Mean age was 39.3 ± 10.1 years. Of 958, 474 (49.47%) were female. Poor sleep quality was associated with 2.197-fold increased risk of prediabetes after adjustment for age, gender, body mass index, and metabolic syndrome.Conclusion. This study provides evidences that subjects with poor sleep quality are more likely to develop prediabetes than people with good sleep quality.

ObjectiveTo investigate the associations of sleep duration, midday napping, sleep quality, and change in sleep duration with risk of incident stroke and stroke subtypes.MethodsAmong 31,750 participants aged 61.7 years on average at baseline from the Dongfeng-Tongji cohort, we used Cox regression models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for incident stroke.ResultsCompared with sleeping 7 to <8 hours/night, those reporting longer sleep duration (≥9 hours/night) had a greater risk of total stroke (hazard ratio [HR] 1.23; 95% confidence interval [CI] 1.07–1.41), while shorter sleep (<6 hours/night) had no significant effect on stroke risk. The HR (95% CI) of total stroke was 1.25 (1.03–1.53) for midday napping >90 minutes vs 1–30 minutes. The results were similar for ischemic stroke. Compared with good sleep quality, those with poor sleep quality showed a 29%, 28%, and 56% higher risk of total, ischemic, and hemorrhagic stroke, respectively. Moreover, we observed significant joint effects of sleeping ≥9 hours/night and midday napping >90 minutes (HR 1.85; 95% CI 1.28–2.66), and sleeping ≥9 hours/night and poor sleep quality (HR 1.82; 95% CI 1.33–2.48) on risk of total stroke. Furthermore, compared with persistently sleeping 7–9 hours/night, those who persistently slept ≥9 hours/night or switched from 7 to 9 hours to ≥9 hours/night had a higher risk of total stroke.ConclusionsLong sleep duration, long midday napping, and poor sleep quality were independently and jointly associated with higher risks of incident stroke. Persistently long sleep duration or switch from average to long sleep duration increased the risk of stroke.

Objectives: In this study, we explored the association between sleep quality, duration and prevalence of rheumatoid arthritis (RA) among low-income adults in rural areas of China. Methods: Face-to-face investigation were conducted in 2017, and completed questionnaires were obtained from 16,648 individuals. Sleep quality and duration were evaluated using the standard Pittsburgh Sleep Quality Index. RA was based on self-reported physician diagnosis. Logistic regression analysis and restricted cubic spline models were performed. Results: Sleep duration shorter than 7 hours was associated with increased odds of RA, with an odds ratio (OR) of 1.49 for 6–<7 hours and 1.70 for <6 hours. Poor sleep quality was associated with RA, with an OR of 1.68. The combination category of poor sleep quality and any group of sleep duration was associated with a significantly increased risk of developing RA. Combined groups of good sleep quality with short sleep duration (<7 hours) were also found to be related to prevalence of RA. There was a non-linear relationship between sleep quality, duration and the odds of RA. Conclusions: Poor sleep quality and short sleep duration may be trigger or risk factors for RA.
