We investigated the association between serum level of oxidized low-density lipoprotein (oxLDL) and risk of cognitive impairment (dementia or mild cognitive impairment) among 572 nondemented community-dwelling women from a prospective cohort study of aging. After 5 years of follow-up, 228 (39.9%) developed cognitive impairment; and this did not differ by tertile of baseline oxLDL level (highest compared with lowest tertile 38.2% vs. 39.5%; odds ratio, 0.90; 95% confidence interval, 0.63-1.43). Multivariate adjustment produced similar results (odds ratio, 0.91; 95% confidence interval, 0.60-1.39). These findings suggest that increased levels of serum oxLDL are not associated with a greater risk of incident cognitive impairment in older women.
