“…Previous studies have also shown that 'short' sleep duration is associated with 'poor' self-rated health in the populations of young adults [11], adults [12,13], and the elderly [6,14]. Contrary to our findings, Steptoe et al [10] showed that only 'short' sleep duration was associated with 'poor' self-rated health in a sample of 17,456 university students.…”

“…In both groups, studies have shown a U-shaped association between sleep duration and self-rated health, that is, both short and long sleep are associated with 'poor' self-rated health. Only a handful of studies examined the same associations in the elderly [6,14] and showed similar results, where both 'short' and 'long' sleep duration were associated with reporting 'poor' self-rated health. However, studies examining the associations between sleep quality and self-rated health are lacking, especially in the elderly population.…”

The main purpose of the present study was to explore the associations of sleep duration and sleep quality with self-rated health. In this cross-sectional study, participants were 894 elderly individuals. Self-rated health, sleep duration, and sleep quality were self-reported. The associations were examined using multiple logistic regression analyses.After adjusting for sex, physical activity, smoking consumption, alcohol consumption, psychological distress, socioeconomic status, and chronic disease/s, sleeping <6 h (OR (Odds ratio) = 3.21; 95% CI (95 percent confident interval) 1.61 to 6.39), 6–7 h (OR = 2.47; 95% CI 1.40 to 4.36), 8–9 h (OR = 3.26; 95% CI 1.82 to 5.83), and >9 h (OR = 3.62; 95% CI 1.57 to 8.34) and having ‘poor’ sleep quality (≥5 points; OR = 2.33; 95% CI 1.46 to 3.73) were associated with ‘poor’ self-rated health. When sleep duration and sleep quality were entered simultaneously into the model, the same associations remained. Our findings provide evidence that both ‘short’ and ‘long’ sleep and ‘poor’ sleep quality are associated with ‘poor’ self-rated health. Thus, interventions that promote healthy sleep hygiene in the elderly are warranted.

“…The mean sleep duration was 8.3 h, which is similar to a previous national study among individuals 50 years and older in South Africa (8.6 h) [ 12 ], but lower than in a national study on persons 50 years and older in Ghana (7.7 h), China (7.6 h), and India (7.1 h) [ 25 ]. The prevalence of short sleep (13.1%) was similar to the national study on persons 50 years and older in South Africa (11.4%), [ 12 ] but was lower than in individuals 50 years and older in China (20.3%) and India (29.3%) [ 27 ], and the prevalence of long sleep (40.0%) was similar to the national study on persons 50 years and older in South Africa (43.5%) [ 12 ], but was higher than in individuals 50 years and older in China (25.9%) and India (14.9%) [ 27 ].…”

This study aims to investigate sleep duration and its association with sociodemographic, health behaviour, mental health, and chronic disease factors among rural individuals 40 years and older in South Africa. Cross-sectional data from the “Health and Aging in Africa: A Longitudinal Study of an INDEPTH community in South Africa” (HAALSI) baseline survey were analysed. Socio-demographic, clinical, health, and sleep duration data were collected. The total sample included 4725 persons 40 years and older (mean age 61.5 years, SD = 13.0, age range of 40–111 years) in one sub-district in rural South Africa. The mean sleep duration was 8.28 ± 1.93 h. Short (<7 h) and long (≥9 h) sleepers accounted for 13.1% and 40.0% of the sample, respectively. In adjusted multinomial logistic regression, greater wealth status (p < 0.05), inadequate fruit and vegetable consumption (p < 0.001), and depressive symptoms (p < 0.05) were associated with a higher odds and physical inactivity (p < 0.05) with a lower odds of short sleep duration. Being male (p < 0.001) and depressive symptoms (p < 0.001) were associated with a higher odds and being 50 to 69 years old (p < 0.01), having Grade 1 to 11 education (p < 0.05), and greater wealth status (p < 0.001) were associated with a lower odds of long sleep duration. In adjusted multinomial logistic regression, compared to normal sleepers, long sleepers were more likely to have myocardial infarction (p < 0.05). In unadjusted analysis, compared to normal sleepers, short sleepers were more likely to have cataracts (p < 0.05). This study found that a significant proportion of rural dwellers 40 years and older in South Africa had a short sleep duration and a high proportion had a long sleep duration. Some associations, such as depression and myocardial infarction, with short and/or long sleep duration were confirmed, while no associations were found for many chronic conditions.

“…In the Indian component of this study, 4,500 older Indian adults from largely rural self-report average sleep duration of 7.1 hours (Gildner et al, 2014). About 30% of these individuals report sleeping six or fewer hours per night (Selvamani et al, 2018). Given that people tend to substantially overestimate their own sleep, such self-reported measures likely underestimate the true extent of sleep deprivation (Lauderdale et al, 2008).…”
