ABSTRACT Sleep quality is an important predictor of well being in the elderly. However, the effects of depression and physical activity on sleep quality among elderly are less clear.
One hundred older individuals who met the inclusion criteria were randomly sampled from a Taipei district elderly residential list. Door-to-door interviews were conducted. Sleep quality (the outcome variable), physical activity and depression symptoms were measured by the Pittsburgh Sleep Quality Index (PSQI), Physical Activity Scale for the Elderly (PASE), and Taiwanese Depression Questionnaire (TDQ), respectively. Logistic regression was performed to examine the relationship between the above major variables.
A half of the elderly had short sleep onset (<15 minutes) but reported poor sleep quality (PSQI > 5). Twenty-two percent of community-dwelling elders used psychoactive medication for sleep. The prevalence of depressive disorders (TDQ ≥ 19) was 7%. Although both physical activity and depression were significantly associated with sleep quality in the univariate analysis, only depression remained significant after adjusting for age, gender, education, marital status, and chronic illness confounders in logistic regression (OR=1.31, 95% confidence interval=1.12-1.52).
Elderly depression symptoms was the only factor significantly associating with poor sleep quality after adjustment. Higher level of physical activity was associated with better sleep quality in univariate analysis but not in multivariate analysis, which considered the factor of elderly depression symptoms in the elderly. The role of physical activity in late life potentially influence sleep quality but may have less significance compared with depression. Therefore, we suggest the need for more future research to investigate the relationship between elderly people's sleep and physical activity.

    ABSTRACT: Aging causes several physiological alterations, including alterations in sleep. It is possible that difficulty sleeping can be exacerbated by increased inflammation in older individuals. Moderate exercise training may be a modality of non-pharmacological treatment for sleep disorders and inflammation. We aimed to assess the effects of moderate exercise training on sleep in elderly people as well as their cytokine profiles. Additionally, we examined the effect of exercise training on quality of life parameters using a SF-36 questionnaire. Twenty-two male, sedentary, healthy, elderly volunteers performed moderate training for 60min/day, 3days/week for 24week at a work rate equivalent to their ventilatory aerobic threshold. The environment was kept at a temperature of 23±2°C, with a humidity of 60±5%. Blood and polysomnograph were collected twice: at baseline (1week before training began) and after 6months of training. Training increased aerobic capacity parameters (p<0.0001), decreased REM latency (p<0.02), and decreased time awake (p<0.05). After training, the levels of IL-6 (p<0.0001) and TNF-α (p<0.0001) and the ratio of TNF-α/IL-10 (p<0.0001) were decreased, whereas IL-10 levels were increased after training (p<0.001). Furthermore, exercise training was shown to improve quality of life parameters. Our results suggest that 6months of training can improve sleep in the elderly and is related to the anti-inflammatory effect of moderate training, which modifies cytokine profiles.

    ABSTRACT: Purpose: The purpose of this study was to identify the prevalence and risk factors of sleep disturbance among community dwelling adults in Korea. Methods: Data were collected from nine hundred fifty nine adults dwelling in a metropolitan city in Korea. Subjects were older than 45 years, did not take medication for sleep problems on a regular basis, and did not work at night. The Pittsburgh Sleep Quality Index was used to collect data about sleep disturbance. Sociodemographic, life style, and health related factors were included as risk factors. Chi square test and logistic stepwise regression were used to identify the risk factors. Results: The prevalence of sleep disturbance was 13.1%. The significant risk factors were being female, age, number of toilet use at night, perceived health, and pain. Risk factors were somewhat different by gender. Emotional and job status were the risk factors only for men and menopausal status were for women. Conclusion: Prevalence of sleep disturbance in community dwelling adults in Korea was not greater than those dwelling in other countries. Females, older adults, the number of toilet use at night, perceived health, and pain were the most important risk factors for sleep disturbances. Gender was a factor in reported sleep disturbances. It might be useful to investigate the factors that contribute to the number of toilet use at night as this might have some underlying factors that could be corrected.
