Poor sleep quality is an overlooked risk for geriatric syndromes in older adults with type 2 diabetes mellitus

ABSTRACT

Background

Aging and type 2 diabetes mellitus (DM) are two different conditions that impair sleep quality. The primary objective of this study was to investigate the impact of sleep quality on geriatric syndromes in older diabetic adults.

Methods

Comprehensive geriatric assessment was performed on 236 patients. The assessment included the Geriatric Depression Scale (GDS), Beck Anxiety Inventory (BAI), European Quality of Life Questionnaire (EQ-5D), Mini Mental Statement Examination (MMSE), Pittsburgh Sleep Quality Index (PSQI), Mini Nutritional Assessment, and measurement of handgrip strength (HGS).

Results

Of the participants, 55% had DM, and 61.4% had poor sleep quality. Poor sleep prevalence was higher in diabetic patients (68.5%) than in non-diabetics (52.8%). Diabetic patients with poor sleep quality had higher frequencies of chronic pain, recurrent urinary tract infections, confirmed sarcopenia, and frailty (p = 0.015, p < 0.001, p = 0.027, and p < 0.001, respectively), a higher number of comorbidities and higher GDS and BAI scores (p = 0.046, p < 0.001 and p < 0.001, respectively), and lower scores of activities of daily living, HGS, and EQ-5D index (p = 0.023, p = 0.004, and p < 0.001, respectively) compared to diabetic patients with good sleep quality. According to the correlation analysis results, PSQI score had a positive correlation with GDS score (r = 0.461, p < 0.001) and a negative correlation with Mini Nutritional Assessment score (r = –0.317, p < 0.001), skeletal muscle mass index (r = –0.283, p = 0.002) and HGS (r = –0.307, p < 0.001) scores in diabetic older adults.

Conclusion

Poor sleep quality in older diabetic patients has a negative impact on several geriatric syndromes. Our findings suggest that poor sleep quality is an independent risk factor for depression, malnutrition, and lower muscle mass in older diabetic adults. Improving sleep quality may play a crucial role in preventing and managing geriatric syndromes in this population.
