Association between OSA and cognitive disorders by race.
| Prevalence of probable OSA (%) | CIND | Dementia | |||
|---|---|---|---|---|---|
| Crude OR (95% CI) | Adjusted ORa (95% CI) | Crude OR (95% CI) | Adjusted ORa (95% CI) | ||
| Total sample | 59.7 | ||||
| High vs low OSA risk | 1.21 (1.09, 1.34) | 1.22 (1.08, 1.37) | 1.12 (0.94, 1.34) | 1.27 (1.04, 1.54) | |
| Whites | 58.1 | ||||
| High vs low OSA risk | 1.25 (1.10, 1.42) | 1.35 (1.17, 1.57) | 1.04 (0.83, 1.32) | 1.24 (0.96, 1.60) | |
| Non-whites | 66.3 | ||||
| High vs low OSA risk | 1.01 (0.84, 1.21) | 0.98 (0.81, 1.19) | 1.13 (0.86, 1.48) | 1.23 (0.91, 1.66) | |
Association (adjusted OR and 95% CI) between OSA risk (exposure) and CIND or dementia (outcome), by race (Whites and non-Whites) (imputed dataset). aAdjusted for age, education, marital status, smoking, alcohol, and physical activity. The models for the total population were further adjusted for race/ethnicity. CI = confidence interval, CIND = cognitive impairment not dementia, OR = odds ratio, OSA = obstructive sleep apnea.
