Objective To investigate the assessment and influencing factors of the cerebrovascular function in 40-60 years old women in Guiyang city,and to provide information for the prevention of stroke in menopausal women.Methods Self-designed questionnaire was used among randomly selected healthy women aged 40-60 years who received health checkup from April 2016 to April 2017 in the Medical Examination Center of Affiliated Hospital of Guizhou Medical University.Levels of height,weight,blood pressure,blood lipid,blood glucose,blood uric acid and the cerebral hemodynamics were checked,comparing the influence of different factors for cerebrovascular function integral value differences,and assess the risk of stroke.Results A total of 439 cases were included in the study,the number of cases with abnormal cerebro vascular function (the score of cerebro vascular function score ＜75) accounted for 13.2％ (58/439).Increased age,being ethnic minorities,menopause,obesity,high blood pressure,high blood sugar,high blood uric acid,increased high-density lipoprotein cholesterol (HDL-C),total cholesterol and triglycerides were related to the abnormal scores of brain function,and the difference was statistically significant (P＜0.05).Logistic regression analysis indicated that minority,High HDL-C [OR(95％CI):0.38 (0.25-0.58),P=0.036],obesity [OR(95％CI):11.62 (5.17-26.14),P=0.001] and hypertension [OR(95％CI):14.87(2.46-89.75),P=0.001] are the factors influencing the cerebro vascular function.Conclusion The proportion of abnormal cerebrovascular function was 13.2％.Increased HDL-C is the protective factor for perimenopausal cerebro vascular function.Minority,obesity and high blood pressure are risk factors for cerebro vascular function,of which,the association between hypertension and cerebro vascular function worsens with elevated blood pressure.
