This investigation into sleep problems among people of advanced age included 251 Māori and 398 non-Māori aged 79–90 years. The study researchers found that 25.5% of Māori and 31.7% of non-Māori reported a current sleep problem. Reporting a current sleep problem was more likely among non-Māori (adjusted OR 0.52; 95% CI, 0.30 to 0.90) and among those who reported a past sleep problem (adjusted OR 2.67; 95% CI, 1.25 to 5.72). In logistic regression analyses, sleep problems were related to poorer self-rated physical and mental health, as well as falls over the previous year. For instance, in regard to mental health, those reporting a current sleep problem were more likely to also score highly for symptoms of depression on the Geriatric Depression Scale than those who did not report a current sleep problem (OR 4.42; 95% CI, 2.40 to 8.14).
