Objective: To explore the correlation between conventional vascular risk factors and the onset of Alzheimer's disease(AD). Methods: 495 subjects from Beijing Tiantan Hospital in 2015-2018 entered the study, including 219 AD patients with positive β-amyloid plaque imaging by PET-CT (AD group), and 276 normal cognitive individuals matched by age and gender (control group). Brain CT or MRI of all subjects showed no abnormal or mild - moderate white matter changes, excluding infarctions of cerebral cortex and medial thalamus and other lesions. Data of conventional vascular risk factors for all subjects were collected including hypertension, diabetes, hyperlipemia, smoking, body mass index (BMI).The correlation between conventionalvascular risk factors andonset of AD was analyzed by multivariate logistic regression analysis. Results: Multivariate logistic regression analysis found that the frequency of diabetes was positive related to the onset of AD [OR (95% CI): 1.796 (1.002~3.219), P=0.049], while level of BMI [OR (95% CI): 0.897 (0.846~0.953), P<0.001] and the frequency of hypertension [OR (95% CI): 0.424 (0.285~0.632), P<0.001] were negative related to onset of AD. Conclusion: The results of this study found that diabetes and lower BMI level might be related to the onset of AD, and didn't support the influence of hypertension on the onset of AD. Prospective cohort studies are need to confirm the above findings.
