多种维他命可避免老年人感染的证据不足
今天在线出版的BMJ的研究发现，多种维他命和矿物质的补充可避免老年人感染的证据不足。
年龄老化使发生感染的风险增加。随着发达国家老年人口的增加,通过补充物质预防感染的研究逐渐引起重视。
研究人员在老年人感染方面进行了8项补充维他命和矿物质的的研究。 虽然其中3项研究报告显示减少感染的时间，但是全部的证据还是不足。
专家说，研究并不支持常规地补充维他命和矿物质，然而，研究结果显示还需要更进一步地研究这一领域。

Not enough evidence that multivitamins prevent infections in the elderly
There is currently not enough evidence to suggest that multivitamin and mineral supplements prevent infections in elderly people, finds a study published online by the BMJ today.
Ageing is associated with an increased risk of infection. So, as the number of elderly people in developed nations continues to rise, there has been great interest in the use of supplements to help prevent infections.
Researchers identified eight trials evaluating the effect of multivitamin and mineral supplements on infections in elderly people. Although three studies reported fewer days spent with infection, overall the evidence was weak and conflicting.
The evidence does not support a policy recommending the routine use of such supplements in all elderly people, say the authors. However, the results are sufficiently encouraging to warrant further and more expansive studies in this area of considerable public health importance.
