SUMMARY  
Objectives: To investigate the association between sleep disturbances and sarcopenia  
among older adults. Subjects and methods: A cross-sectional study on 522 patients aged 60  
years old and over treated at the National Geriatric Hospital. Patients were interviewed  
according to a uniform questionnaire; sleep disturbances were assessed by using the PSQI  
instrument. The definition of the Asian Working Group for Sarcopenia 2019 was used for  
diagnosis of sarcopenia. Results: The mean age of the patients was 70.91 8.67 years. The  
ratio of female/male was 1.45. The prevalence of sleep disturbances in older adults was 85.8%.  
There was an association between sleep disturbance and sarcopenia among older adults with  
statistical significance after using both unilabiate and multivariable model logistic. Conclusion:  
The prevalence of sleep disturbance was high and was associated with sarcopenia among older  
people. Sleep disorders are very common in older adults and there was an association between  
sleep disturbance and sarcopenia. The sleep disturbance among patients in general, those with  
sarcopenia in particular, should be paid much attention.  
* Keywords: Sleep disturbance; The elderly; Sarcopenia.  
INTRODUCTION  
The above factors are attributed to a  
reduction in skeletal muscle mass,  
strength, and function. A combination of  
these changes has been called sarcopenia.  
Sarcopenia is a common clinical problem  
in people over 50 years of age, which  
leads to severe adverse outcomes,  
including loss of function, disability, and  
frailty. Degenerative changes in muscle  
tissue, unrelated to sarcopenia, were  
diagnosed in 14% of the male population  
and 13% of the female population in the  
age group 65 - 75 years, and 56% of men  
and 53% of women in the age group 80  
years or older [2].  
Aging is a worldwide phenomenon with  
significant social, economic, and health  
implications. Sleep disturbance is a group  
of conditions that affect the ability to sleep  
well on a regular basis and a decline in the  
quality of life, and it is considered to be a  
serious health problem. Approximately  
50% of older adults have complaints of  
sleep problems in their daily life [1]. Sleep  
disturbance is associated with a decline in  
activities of daily living, cognitive function,  
falling and slows down basic metabolism.

Nonetheless, the medical literature study was 522. Data were collected by  
using a unified research record.  
shows a gap between the role of sleep  
quality and its effects on the prevalence  
of sarcopenia [3]. Vietnam will soon move  
to an aging population pyramid, so earlier  
understanding of the relationship between  
sleep disturbance and sarcopenia is  
important for providing potential targets  
for preventing and treating sarcopenia.  
Besides, prevention is an advantage for  
improving people’s health status and  
decreasing the cost burden. We conduct  
this study: To investigate the association  
between sleep disturbances and sarcopenia  
among older adults.  
* Variables:  
- Demographic information includes:  
full name, age, sex, residual place, marital  
status, educational level.  
- Sleep disturbance was assessed by  
using the PSQI instrument. Total score  
PSQI is calculated by the sum of 7  
components. Evaluation results: Good  
sleep (< 5 points), poor sleep (5 points).  
- Sarcopenia diagnosis was performed  
by the standards of the Asian Working  
Group for Sarcopenia (AWGS). Based on  
the AWGS, sarcopenia is diagnosed with  
(1) low muscle mass and (2) low HGS [4].

A total of 522 participants, the age ranged from 60 to 98, with the mean age being  
70.91 8.67 years old. The greatest distribution was generated by people aged from  
60 to 69, with the percentage of 50.8%, of which the highest percentage of sarcopenia  
in the older adults aged 80 and above was 93.1%. Female accounted for 59.2% (n = 309),  
higher than the male (40.8%) (n = 213). The ratio of female/male was 1.45. More than  
half of the participants (78.7%) got married. The majority lived with family (95.8%).  
Among participants living in rural, the prevalence of sarcopenia was higher compared  
to people living in urban (69.9% and 56.0%). These differences were statistically  
significant with p = 0.001, respectively.

Table 2 demonstrated sleep disturbance factors related to sarcopenia. Among sarcopenia  
older adults, the people had long sleep latency more than the ones getting short sleep  
latency with OR = 1.017, 95%CI: 1.006 - 1.028. This rate was significant (p = 0.002).  
Patients with long sleep duration (OR = 0.759, 95%CI: 1.047 - 10.041, p = 0.027)  
and best sleep efficiency (OR = 0.988, 95%CI: 0.977 - 0.999, p = 0.026) had lower  
odds in sarcopenia. Patients with bad sleep quality (OR = 2.434, 95%CI: 1.801 - 3.288,  
p < 0.001) had higher odds in sarcopenia.  
Patients with sleep medication (OR = 1.550, 95%CI:1.160 - 2.071, p = 0.003) had higher  
odds in sarcopenia.

Regarding physical function in poor sleepers, the rate of impaired people higher  
2.007 times than the rate of normal ones (95%CI: 1.501 - 2.683). It was statistic significant  
(p < 0.001).  
Patients with sleep disturbances 2.086 (95%CI: 1.270 - 3.425) had higher odds in  
sarcopenia. This rate was significant (p = 0.004).

After adjustment for age, low education level, malnutrition, depression was associated

(MOR) 2.090, 95%CI (1.224 - 3.568) higher than before adjustment OR = 2.086,  
95%CI: 1.270 - 3.425) for sleep disturbances.  
DISCUSSION  
After adjustment for age, education level,  
nutrition status, and depression were  
associated with increased odds of greater  
sarcopenia remain significant (multivariable  
odds ratio (MOR) 2.090, 95%CI (1.224 -  
3.568), p = 0.007). This result similar to a  
systematic review research [7] showed  
that the prevalence of sarcopenia appears  
to be associated with sleep quality, with  
higher prevalence values in older adults  
who have an inadequate sleep. In addition,  
this prevalence seems to be higher in  
men than in women. This result lower with  
a study in Japan in 2019 with 318 patients.  
Adjusted odds ratios of sarcopenia and  
sleep disorder were 6.04 in men (95%CI:  
1.71 - 21.36, p=0.005) and 6.33 in women  
The majority of the elderly getting poor  
sleep was 448 people (85.80%) with the  
score of PSQI ranging from 1 to 23, mean  
score of 9.39 (SD = 4.37).  
In Malaysia’s study, the PSQI score  
ranged from 0 to 16 with a mean score of  
7.1 (SD 3.4) and the majority of poor  
sleep (76.8%, n = 116) [5]. The result was  
higher than a study in Japan (2019), the  
prevalence of sleep disorder was 44.8%.  
There was a statistically significant  
association between sleep disturbance  
and sarcopenia (p = 0.004). Patients with  
sleep disturbances (OR = 2.086, 95%CI:  
1.270 - 3.425) had high odds in sarcopenia.  
175  
Journal OF MILITARY PHARMACO - MEDICINE N05 - 2021  
(95%CI: 1.91 - 20.97, p=0.003) found a  
statistically significant association between  
sarcopenia and sleep disorder in older  
patients with diabetes using SARCF  
questionnaire [6]. This difference between  
this study and research can be explained  
by the fact that the sample size (n = 522  
> 318) and the prevalence of sarcopenia  
between each research were different.  
Among sarcopenia older adults, the people  
had long sleep latency more than the  
ones getting short sleep latency with  
OR = 1.017, 95%CI: 1.006 - 1.028. This  
rate was significant (p = 0.002). In the  
sarcopenia group, the prevalence of sleep  
disturbance was higher than in this study  
[8]. A research in 2019 reported lowest  
category of sleep duration (under 6h)  
versus the reference category (6 - 8h)  
was significantly related to the increased  
risk of sarcopenia (OR = 1.71; 95%CI:  
1.11 - 2.64). This meta-analysis indicates  
that the public should be aware of the  
negative consequences of long and short  
sleep for sarcopenia, especially among  
women [9]. A cross-sectional study of 607  
participants aged 60 years and older  
living in China. In women, the prevalence  
of sarcopenia was significantly higher in  
the short sleep duration group (< 6 hours  
- 27.5%) and long sleep duration group  
(> 8hours - 22.2%) compared with  
women in the normal sleep duration group  
(6 - 8 hours - 13.9%) (respectively; p  
=0.014). Similar results were found in  
men; however, the differences between  
groups were not statistically significant  
(18.5%, 20.6%, and 13.0%, respectively; p  
= 0.356). A U-shape relationship between  
self-reported  
sleep  
duration  
and  
sarcopenia was identified in a population  
of Chinese community-dwelling older  
adults, especially in women. These results  
could have a practical application for  
public health since they can help us to  
consider sleep quality as a risk factor, as  
well as the need to incorporate therapies  
in order to improve the sleep quality and  
to reduce the negative effects of age-  
associated sarcopenia.  
CONCLUSION  
The prevalence of sleep disturbance  
was high and was associated with  
sarcopenia among older people. Sleep  
disorders are very common in older adults  
and there was an association between  
sleep disturbance and sarcopenia.  
Medical staffs should concern more about  
the patient’s sleep disturbance, especially  
in patients with sarcopenia.
