Researchers in the United States 7 released the report says,Men over the age of 50 concerned,Daily use of a piece of compound vitamin will not decrease myocardial infarction/Stroke, and the risk of cardioascular disease.

　　相关研究报告当天发表在新一期《美国医学会杂志》上。哈佛大学医学院附属布里格姆妇科医院研究人员分析了参与“医生健康研究II”项目的近1.5万名男性的数据。该项目始于1997年，共招募了约1.5万名年龄在50岁以上的美国男性医生，其中包括754名有主要心血管疾病病史者。试验参与者被随机要求服用复合维生素或安慰剂，对他们进行的随访截至去年6月结束。

　　在平均时间为11.2年的随访中，共有1732人出现主要心血管疾病，其中服用维生素组稍低于服用安慰剂组，但这一差异并不具有统计学上的显著意义。

In the mean time of 11.2 years of follow-up,A total of 1732 people appear major cardiovascular disease,The vitamin group slightly lower than placebo,But the difference does not have statistical significance.

　　研究人员表示，尽管维生素的长期健康裨益存在不确定性，但美国仍有很多成年人为防止慢性疾病而服用维生素补充剂，其中一些人认为可因此获益从而较少进行其他预防性保健行为。这项新研究则表明，维生素补充剂永远不可能替代健康饮食，可能一些人需要维生素补充剂，但对大部分人而言并非如此。(记者任海军）
