“…This is in accordance with an Italian centenarian study which reported that long-lived individuals had better selfrated quality of sleep. 28 This may also support the notion that the majority of healthy elders could experience satisfactory sleep quality. 49 Overall, these findings may support the argument that sleep problems at old and oldest-old ages likely arise from a variety of physiological and psychosocial factors rather than aging per se.…”

“…Education of Chinese elders is a variable reflecting their childhood condition rather than adult condition, since most current Chinese elders, especially women, could not go to school when they were children because of very indicated that Chinese elders who slept for 7-9 h per day were a homogeneous group rather a heterogeneous one. If these 3 categories of sleep hours were more likely to have lower mortality risks and better health conditions than other categories as noted in previous studies, [24][25][26][27][28][29][30][31] we may speculate that these elders who slept 7-9 h per day were more likely to be healthy, and that healthy elders, regardless of their characteristics, shared a similar frequency of sleep duration.…”

“…28 Empirical studies have shown that approximately 3% to 7% of seniors in China use sleep medicines, 1,3 so such biases might not be very harmful to our general conclusions. However, further research that controls for these confounders is warranted.…”

“…3 It is well documented that poor quality of sleep and insufficient or excessive hours of sleep are associated with poor physical function, poor cognitive function, higher morbidity, poor quality of life, and excessive mortality rates. [24][25][26][27][28][29][30][31] However, many studies have also shown that poor health is a risk factor for poor sleep quality. For instance, self-reported sleep problems are significantly greater among those with higher levels of depression/anxiety, 11 chronic illnesses, 1,11,20 mental illness, 1,2,11 poor self-rated health, 1,3,11 and poor functional status.…”

Study Objectives: To examine factors associated with self-reported sleep quality and duration among very old adults in China. Design: Cross-sectional analysis of the 2005 wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Setting: In-home interview with older adults in 22 provinces in mainland China. Participants: A total of 15,638 individuals aged 65 and older (5,047 aged 65-79, 3,870 aged 80-89, 3,927 aged 90-99, and 2,794 aged 100 and older, including 6,688 men and 8,950 women). Interventions: N/A Measurements and Results: Two self-reported sleep questions together with numerous sociodemographic and health status measures were used in this study. Sixty-five per cent of Chinese elders reported good quality of sleep. The average number of self-reported hours of sleep was 7.5 (SD 1.9), with 13.1%, 16.2%, 18.0%, 28.0%, 9.2%, and 15.5% reporting ≤ 5, 6, 7, 8, 9, and ≥ 10 hours, respectively (weighted). Multivariate analyses showed that male gender, rural residence, Han ethnicity, higher socioeconomic status, and good health conditions were positively associated with good quality of sleep. All other factors being equal, octogenarians, nonagenarians, and centenarians were more likely to have good sleep quality than the young elders aged 65-79. Elders with poorer health status or older age were more likely to have either relatively shorter (≤ 6 h) or longer (≥ 10 h) sleep duration. Married elders were more likely to have an average duration between these two values. Except for some geographic variations, associations between all other factors and sleep duration were weak compared to the effects of health. Conclusions: Age and health conditions are the two most important factors associated with self-reported sleep quality and duration. Good quality of sleep among long-lived old adults may have some implications for achieving healthy longevity. A commentary on this article appears in this issue on page 575.

“…Gu et al (2010) found that quality of sleep of the very elderly did not differ substantially from that of the young elders. Tafaro et al (2007) also reported that long-lived individuals showed better self-rated sleep quality. This disagreement could be explained by the following factors: (1) these two studies (Gu et al 2010;Tafaro et al 2007) used self-rated quality of sleep, which is a subjective measurement; (2) the participants included in these two studies were healthier than those included in our study; and (3) the healthy long-lived participants might have their own perception of what is "acceptable" sleep and, therefore, did not report poor sleep quality even if objective quality of sleep does in fact change with advancing age.…”

In this study, we examined the existence of relationship between sleep quality and dementia in subjects aged 90 years and above. The sample included 216 men and 444 women. Dementia and sleep quality were measured with 30-item mini-mental state examination (MMSE) and the Pittsburgh sleep quality index, respectively. Subjects with dementia had higher sleep quality score (7.83 ± 2.15 vs. 5.22 ± 2.49; P < 0.0001), longer sleep latency (50.97 ± 21.33 vs. 37.61 ± 12.53; P < 0.0001), and a lower sleep efficiency percentage (73.95 ± 8.783 vs. 81.32 ± 10.21; P < 0.0001) and more likely to report poor sleep quality (25.42 vs.17.13 %; P 0 0.035). Subjects with poor sleep quality had significantly lower MMSE scores (P 0 0.007) and higher prevalence of dementia (P 0 0.042). Multiple logistic regressions were performed by adjusting clinical factors that are thought to be associated with dementia or sleep quality. We found that poor sleep quality was a risk factor for dementia (unadjusted odds ratio (OR) 1.719, 95 % confidence interval (CI) 1.138-2.597; adjusted OR 1.759, 95 % CI 1.012-3.057). There was no significant difference in MMSE scores (11.25 ± 3.40, 16.26 ± 5.14, and 15.43 ± 5.51; P 0 0.105) among participants with daily average sleep durations of <5, 5-9, and >9 h, respectively. Among Chinese nonagenarians and centenarians, dementia was correlated with poor sleep quality, longer sleep latency, and lower sleep efficiency percentage.
