“…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]. Most of these previous studies have been conducted in western societies.…”

Objective To investigate the prevalence and associated factors of poor sleep quality among community-dwelling elderly population in a rural area of Northern China. Methods We conducted a cross-sectional survey in August-December 2014 and recruited 2195 participants who were aged 65 years or older and living in Yanlou Town of Yanggu County in western Shandong Province, China. Data on demographics, health-related behaviors, and clinical conditions were collected through structured interviews. The Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality and patterns. Poor sleep quality was defined as a PSQI score > 7. We employed multiple logistic models to relate poor sleep quality to various factors. Results The overall prevalence rates of poor sleep quality were 33.8% in the total sample, 39.2% in women and 26.3% in men (P < 0.01). The most common abnormal sleep domains were prolonged sleep latency (39.7%), decreased sleep duration (31.0%), and reduced habitual sleep efficiency (28.8%). Multiple logistic regression analyses revealed that poor sleep quality was significantly associated with female sex (OR = 1.76, 95% CI 1.46-2.12) and clinical comorbidities such as hypertension (OR = 1.28, 95% CI 1.06-1.54), coronary heart disease (OR = 1.60, 95% CI 1.27-2.00), and chronic obstructive pulmonary disease (OR = 1.82, 95% CI 1.34-2.49). Conclusions The sleep disorders were highly prevalent among the elderly in rural China. Modifiable risk factors such as cardiometabolic risk factors and disorders were associated with poor sleep quality, which might be potential targets for interventions to improve sleep quality in elderly population.

“…In addition, short and long sleep duration can increase home-measured and visit-to-visit BP variability, which are closely related to the development and progression of brain damage by promoting micro-and macro-vascular remodeling, hemodynamic instability, and blood flow imbalance. 22,23 Sleep duration less than 6 or more than 9 hours per day was demonstrated to be one determinant of increased weight, hyperlipidemia, and drop in serum high-density lipoprotein cholesterol. [17][18][19][20][21] Short and long sleep duration has been associated with higher incidence of impaired glucose tolerance or diabetes mellitus and less tight glycemic control in diabetic patients.…”

“…The enhanced sympathetic activity can decrease the responsiveness of pancreatic ß-cells and glucose tolerance, whereas the reduced uptake of glucose by brain following chronic sleep debt may result into higher blood glucose concentrations and favor the development of insulin resistance. 22,23 Sleep duration less than 6 or more than 9 hours per day was demonstrated to be one determinant of increased weight, hyperlipidemia, and drop in serum high-density lipoprotein cholesterol. 24 Sleep loss and fragmentation induce alterations in neuroendocrine hormones, downregulate the satiety hormone leptin, upregulate the appetite stimulating hormone ghrelin, increase hunger and desire for fatty food, and impact energy expenditure through thermoregulation.…”

Stroke is the second cause of death and one of the leading causes of disability. 1 Worldwide, fifteen million people suffer a stroke every year, nearly six million die, and around five million are left permanently disabled. 2,3 The identification of the risk factors of stroke, especially those that can be modified, is of paramount relevance to control the burden of cerebrovascular diseases. 4,5 In the current issue of The Journal of Clinical Hypertension, the study by Dr Hua and colleagues aimed to examine the association between sleep duration and stroke risk in middle-aged and elderly population. 6 The cross-sectional study included 10 516 participants aged ≥45 years from the China Hypertension Survey study, a nationally representative cross-sectional survey designed to provide reliable and evidence-based data on the current status of hypertension and associated factors in Chinese adults. Longer sleep duration was associated with higher prevalence of stroke: the relationship resulted linear in non-hypertensive patients with a turning point of the smooth curve at 8 hours, whereas a threshold effect was found in hypertensive individuals. 6 Despite methodological issues inherent to the cross-sectional and self-reported nature of data, which may be subjected to recall biases and possible residual or unmeasured confounders, the study can offer intriguing insights for the understanding of behavioral contributors to stroke. | S LEEP DUR ATI ON AND S TROK E RIS KSleep is a tightly regulated phenomenon that takes up approximately to one-third of our lifetime. Although the actual purposes of sleep are still to be fully elucidated, there is indisputable evidence that it serves essential functions and affects many physiological processes.The average need for adults is between 7 and 9 hours of sound sleep per day on a regular basis, and deviations from such rhythm can have negative consequences for health. Epidemiological studies investigating the putative effect of habitual sleep on cerebrovascular risk demonstrated a J-shaped association between sleep duration and stroke incidence. Both insufficient and excessive sleep are predictors for future stroke, and the association is stronger for long than short sleep. 7 It has been estimated that every 1-hour increase in sleep duration can increase the risk of stroke by 10%-15% and individuals sleeping more than 8 hours can be approximately 50% more susceptible to stroke than those with normal sleep duration through 10 years of observation. 8Notably, this trend has been consistently identified across studies irrespective of nationality or ethnicity and after the adjustment for potential confounders like education, employment status, family income, depression, physical activities, and sleep-disordered breathing-related symptoms.Interestingly, sleep duration can significantly affect the traditional risk factors for stroke. The Sleep Hearth Health Study was the first one to suggest that the relationship between sleep duration and hypertension follows a U-shaped curve, being both sho...
