Prevalence and predictors of poor sleep quality in Korean older adults

Abstract

The purposes of this study were to evaluate the levels of sleep quality and to examine its related factors in the elderly Korean adults. A cross-sectional research design was used, and 157 adults, aged from 65 to 89, were recruited from five community health centres in Gyeonggi province and Seoul, Korea. All participants were informed about the purpose of the study and were asked to provide demographic characteristics, chronic conditions, self-rated health, pain, depression, life satisfaction and sleep quality. More than 60% of the participants reported having poor sleep quality. Hierarchical multiple regression analysis showed that age, self-rated health, pain and depression were related to poor sleep quality. The findings suggest that it is important to screen regularly for sleep quality, and attention to depression, poor self-rated health and perceived pain were needed to improve sleep quality of older adults.

Association of Sleep Quality with Socio-Demographic Characteristics in Elderly Referred to Health Centers in Qazvin, Iran

“…These results were in line with the findings of Park et al (Park, Yoo, & Bae, 2013), Oliviera et al (Oliviera Araújo & Ceolim, 2010) and Azri et al (Azri et al, 2016), indicating 64.3% of the Korean elderly, 63.1% of the Brazilian elderly and the Indonesian elderly had poor sleep quality, respectively (Azri et al, 2016). However, Niu et al reported that 33.7% of the Chinese elderly had poor sleep quality (Niu et al, 2016).…”

“…In their study, Park et al reported maximum level of mean sleep quality for the component scores "sleep latency" and "sleep duration" and minimum level of mean sleep quality for the component scores "use of sleep medication"; Further, the obtained results indicated that the sleep quality of the elderly was reduced with aging, but no statistically significant difference was observed, confirming the results of Niu et al (Niu et al, 2016), Kiejna et al (Kiejna, Rymaszewska, Wojtyniak, & Stokwiszewski, 2004) (Niu et al, 2016). However, the study of Park et al on the Korean elderly population showed no significant relationship between gender and sleep quality (Park, Yoo, & Bae, 2013).…”

“…So that, Park et al reported 60% of the elderly had poor sleep quality (Park, Yoo, & Bae, 2013). Sleep disorders in the elderly can be caused by various reason, such as medical disorders, atypical sleep-wake patterns, reduced amount of sleep or poor sleep quality.…”

Self-Reported Sleep Quality, Duration, and Health-Related Quality of Life in Older Chinese: Evidence From a Rural Town in Suzhou, China

“…First, sleep deprivation (ie, poor quality or short duration) has been found to be negatively associated with HRQOL in HK 22 and the Spain. 21 Second, health problems in HRQOL dimensions such as physical functioning, 16,18,19 mental health, 14,17 and pain 18,20 are correlated with extreme sleep duration and poor sleep quality, which may also have negative effect on selfrated health. 36 Third, sleep problems (eg, insomnia) 10,37 or sleep complaints 38 that normally accompany sleep disturbances are reported to have a negative relationship with HRQOL.…”

“…14,17,20,22 This was determined by the education level of study participants of whom nearly half did not receive formal education. A pilot study with a small sample showed that our participants had difficulties in understanding or completing PSQI in a face-to-face interview setting.…”
