神经症患者易于罹患心血管疾病
纽约（路透社健康频道）—英国研究者研究报道：神经症患者易于死于心血管疾病，而那些具有外向性格的人们，则较少因呼吸系统疾病死亡。
苏格兰爱丁堡大学的Beverly A. Shipley及其《心身医学杂志》的同事认为：神经质是一种易于烦恼，并且容易情绪波动的个性倾向，它与焦虑以及抑郁相关，这有助于解释该病与心脏病之间的关系。
Shipley及其研究组认为，外向性格倾向于友善以及喜欢社交。该研究组对神经症以及外向性格如何影响健康展开了协同研究，考察对象是5，424位中年成人的死亡率，他们均在21年前接受了个性测试。
神经症患者死亡率的上升程度与其他任何死亡风险相关，在研究者们对其他相关因素（如体重，酒精饮用量，社会等级以及教育程度）进行校正以后，就失去了这种相关性。
随着个体的神经症病情程度的上升，其死于心血管疾患的风险就上升，在统计学校正后，两者仍具有相关性。
外向性格则降低了个体死于呼吸系统疾患的可能性，但对死亡率其他方面没有影响。
基于以上发现，研究者们总结，神经症与心血管疾患死亡之间的联系可能与基因相关、也可能涉及到社会经济以及行为因素等各个方面。
Neuroticism hard on the heart: study
NEW YORK (Reuters Health) - Neurotic people are more likely to die from cardiovascular disease, while being extroverted seems to protect people from dying from respiratory illness, UK researchers report based on a study they conducted.
Neuroticism -- a proclivity toward worry and emotional ups and downs -- is related to anxiety and depression, which could help explain the relationship with heart trouble, note Beverly A. Shipley of the University of Edinburgh in Scotland and colleagues in the journal Psychosomatic Medicine.
Reports on the health effects of both neuroticism and extroversion, which is the tendency to be friendly and outgoing -- have been mixed, the researchers note. To clarify the relationship, Shipley and her team looked at mortality in 5,424 middle-aged adults who were followed for 21 years after they completed personality tests.
While an increasing degree of neuroticism was tied to an increased risk of death from any cause, the relationship disappeared after the researchers adjusted for other relevant factors such as body weight, alcohol use, social class and education.
Risk of death from cardiovascular disease also climbed as a person's level of neuroticism rose, and the relationship remained significant after statistical adjustment.
Extraversion reduced a person's likelihood of dying from respiratory disease, but had no other effects on mortality.
Based on the findings, the researchers conclude, the neuroticism-cardiovascular disease death link could be related to genes, but socioeconomic and behavioral factors are apt to be involved as well.
