Purpose

This secondary analysis examined the effect of excessive sleepiness on daytime function in older adults with diabetes from the National Sleep Foundation's Sleep and Aging poll.

Methods

Respondents were older adults (N = 1506; age range, 55-84 years) evaluated by telephone survey on their sleep duration, sleep disturbances, daytime functional outcomes, and self-reported height, weight, and comorbidities.

Results

Approximately 16% (n = 244) of the sample acknowledged a diagnosis of diabetes; they were older, had more comorbidities, had a higher body mass index (BMI), and were more likely to be sleepy during the daytime than nondiabetic respondents (all P < .05). Respondents with diabetes who reported frequent daytime sleepiness (n = 50; 20%) had significantly (P < .05) higher BMI, lower self-rated health, and more sleep disturbances than those who were not sleepy (n = 194). Sleepy respondents with diabetes also reported more frequent feelings of depression, decreased pleasure in life, naps, feeling drowsy, or dozing off while driving (all P < .05). Excessive sleepiness was significantly associated (P < .001) with an increased risk for depressive symptoms while controlling for BMI, age, and number of comorbidities.

Conclusions

These results indicate that sleep disturbances affect not only sleep quality but also daytime function in older adults with diabetes.
