Evaluation of the relationship between sleep quality and sleep duration with frailty in older adults

Abstract

Introduction: The older adults population is increasing. Given that population aging is not the only issue and healthy aging is an important issue, it should be considered. Frailty syndrome is one of the factors affecting the health of older adults population and Probably one of the clinical conditions associated with frailty syndrome is sleep quality. Therefore, we conducted this study to evaluation the relationship between sleep quality and sleep duration with frailty in older adults in Naghadeh city.

Methods: This cross-sectional correlational study was performed on 347 elderly people aged 60 years and older in Naghadeh. The sampling method was stratified. Data collection tools included demographic questionnaires, Edmonton frail scale , and Pittsburgh Sleep Quality index. SPSS 25 statistical software was used to analyze the study data.

Results: The mean age of the older people participating in the study was 68.34 ± 7.62. The mean scores of frailty and sleep quality included 4.16 ± 2.99 and 5.69 ± 3.2 . 29.1% of the older people were pre-frail and 1.2% were frail. 42.7% had poor sleep quality. There was a statistically significant correlation between sleep quality and sleep duration (r = 0.63, p˂ 0.000, r = -170 and p˂0.001). The highest average score in the areas of frailty is related to cognition. There was also a statistically significant relationship between all areas of frailty and sleep quality and the most relevant area was mood (r=0/487), medication (r= 0/397) and cognition (r= 0/381).

Conclusion: There is a significant relationship between sleep duration and sleep quality with frailty in theolder people. The most relevant areas of frailty to sleep quality include mood, medication , and cognition, respectively. Effective interventions in improving sleep quality and frailty, especially in the area of mood and contion of frailty , should be designed and implemented.
