维生素D可能预防流行性感冒的研究进展

Vitamin D for Prevention of Influenza

摘要: 流行性感冒是传染性强、传播速度快的上呼吸道疾病，其并发症病毒性肺炎会严重影响身体健康。维生素D具有骨骼健康效应和非骨骼健康效应，特别具有免疫调节作用和预防病毒感染作用。流行病学研究、荟萃分析和临床研究结果显示：维生素D可能具有预防流行性感冒的健康效应。为了收集维生素D确实能够预防流行性感冒的更多证据，相关的临床医师和营养学家应该进一步做好较大规模的随机双盲、安慰剂对照研究。当然，所有这些都不能代替通常预防流行性感冒的建议。

Abstract: Influenza is a viral upper respiratory disease with strong infectivity and rapid spread. Its complication, viral pneumonia will seriously affect the health of the body. Vitamin D has the effects of bone health and non-bone health, especially immune regulation and prevention of virus infection. The results of epidemiological study, meta-analysis and clinical research show that vitamin D may have the health effect of preventing influenza. In order to determine more evidence that vitamin D can actually prevent influenza, the relevant clinicians and nutritionists should further do a large-scale randomized double-blind, placebo-controlled study. Of course, none of this can replace the usual advice for the prevention of influenza.
