Highlights
- •Sleep disorders and malnutrition are two common geriatric syndromes.
- •Poor sleep quality as well as short and long sleep duration are associated with a risk of malnutrition in older adults.
- •More attention should be paid to the sleep conditions and nutritional status of older adults.
Abstract
Objective
To identify the associations between sleep quality, sleep duration and nutritional
status in older adults.
Methods
Data from a total of 6792 community-dwellings adults aged 50 and over from the baseline
of the West China Health and Aging Trend (WCHAT) study were analyzed. Sleep quality
was assessed using the Pittsburgh Sleep Quality Index (PSQI). PSQI scores >5 were
categorized as poor sleep quality. Duration of sleep was classified as <6 h, 6–7 h,
7−8 h, 8–9 h and ≥9 h. The Mini Nutritional Assessment Short Form (MNA-SF) was used
to assess nutritional status and a score <12 was identified as indicating a risk of
malnutrition. Logistic regression models were used to explore the associations.
Results
Of 6792 participants (mean age 62.4 ± 8.3 years, 62.5 % women), 1831 (27.0 %) were
at risk of malnutrition. The prevalence of poor sleep quality was 47.1 %. In the logistic
regression model adjusted for potential confounders, poor sleep quality was significantly
associated with a risk of malnutrition (OR = 1.62, 95 %CI = 1.44, 1.82). Sleep durations
of less than 6 h and of more than 9 h were shown to increase the odds of malnutrition
risk (OR = 1.42, 95 %CI = 1.16, 1.73 and OR = 1.24, 95 %CI = 1.05, 1.47, respectively).
Conclusions
Sleep disorders were significantly associated with malnutrition risk among older adults.
Our results highlight the importance of good sleep quality and enough sleep in order
to maintain good nutritional status in older adults.
