A型行为特征与脑出血的关系

Relationship Between Type A Behavior and Cerebral Hemorrhage

采用配比病例对照研究方法,将162例经颅脑CT扫描确诊的脑出血病例与同等数量的对照组作1:1配比分析,初步探讨了A型行为特征与脑出血的关系。分析结果表明,TH+CH总分,病例组明显地高于对照组(P<0.001),且与脑出血的OR间呈明显的剂量反映关系(OR:1.05,95％CI:1.02～1.07),与B(B+B^-)型性格相比,A型性格脑出血的OR为2.28(95％CI:1.36～3.82)。但是,按高血压病史调整以后,A型性格的作用不再具有显著性意义,提示A型行为特征对脑出血的作用可能是借助于影响血压来实现的。

In order to investigate the relationship between type A behavior and intracerebralhemorrhage, a matched case-control study, with 162 patients with intracerebral hemor-rhage diagnosed by head CT scan and same amount of community controls, wasconducted. Univariate conditional logistic regression analysis showed that a significantdose-response relationship existed between total counts of TH+CH and odds ratio(OR) of intracerebral hemorrhage. Comparing with type B behavior (B+B^-), the ORfor type A behavior was 2.28 (95%CI: 1.36～~3.82). After adjusting y the history ofhypertension, the effects of type A behavior became non-significant. So it was infer-red that type A behavior probably increased the risk of intracerebral hemorrhage byinfluencing blood pressure.
