Epidemiological Study on Risk Factors for arteriosclerosis in cerebral small artery expressed as deep white matter signal hyperintensities on MRIs

我们进行了一项病例对照研究，探讨MRIs深白色信号高信号与体重指数、血压、血液样本生物标志物、既往病史、家族史、生活方式因素、日常生活活动能力和生活质量的关系。39起案件方法：对2003年和2004年经MRI诊断为Fazekas分级2级或2级以上的患者（男20例，女19例）和331例0级或1级对照者进行比较。高血压或眼底硬化改变，血清维生素B12水平低，血清γ-生育酚水平低，每周吃泡菜3-4次或更多，吃用酱料煮的食物每周3-4次或更多次，不能写养老金申请表，增加了脑深部白色病变的风险。以上因素与脑卒中的危险因素基本一致。在同时包括上述危险因素的校正分析中，高血压和高血压和/或视神经基底节硬化改变仍增加脑深部白色病变的危险，高血压和Keith-Wagener分级I及以上的OR（95%可信区间）分别为4.00（1.53-10.45）和3.40（1.25-9.24）。

We have conducted a case-control study on the relation of deep white matter signal hyperintensities on MRIs with body mass index, blood pressure, biomarkers of blood sample, past medical histories, family histories, life style factors, activity of daily living and quality of life. Thirty-nine cases (20 males and 19 females) with the Fazekas classification grade 2 or over diagnosed by MRI were compared with 331 controls with the grade 0 or 1 from the participants of examinees at a human dry doc in 2003 and 2004.Unconditional logistic regression analysis on sex, age and other factors revealed that females, ageing, hypertension, hypertensive or sclerotic change of optic funds, low serum vitamin B12 level, low serum γ tocopherol level, eating pickles 3-4 times per week or more, eating foods boiled down with soy sauce (tsukudani) 3-4 times per week or more, inability of writing down pension application form were increased risk for deep white matter lesions of the brain. Most factors above were consistent with the risk factors for stroke. In adjusted analysis included above risk factors at a time, hypertension and hypertensive and/or sclerotic change of optic funds were still increased the risk of deep white matter lesions of the brain as odds ratio (95% confidence intervals) of hypertension and Keith-Wagener classification I or over were 4.00 (1.53-10.45) and 3.40 (1.25-9.24), respectively.
