BACKGROUND/OBJECTIVE: We examine whether midlife vascular risk factors (VRFs) are associated with increased risk of incident Alzheimer's disease (AD) in a systematic review and meta-analysis of published cohort studies.
METHODS: Original cohort studies were included if they reported adjusted combined odds ratio (COR) and corresponding 95% confidence intervals (CIs) or enough information to quantify the association between risk for AD in late-life and baseline VRFs of midlife.
RESULTS: There were positive and significant associations between high blood pressure (COR 1.31; 95% CI: 1.01-1.70), hypercholesterolemia (COR 1.72; 95% CI: 1.32-2.24), obesity (COR 1.88; 95% CI: 1.32-2.69), and diabetes mellitus in midlife (COR 1.4; 95% CI: 1.25-1.57). Smoking and hyperhomocysteinemia (although only one high-quality paper) were also associated with an increased risk of AD generally.
CONCLUSIONS: These results strengthen the epidemiological evidence that VRFs of midlife significantly increase risk for AD.
