【摘要】：目的根据临床试验结果合成证据,分析有关保健产品、网上信息及相关专业教材关于维生素D促进钙吸收内容的科学性。方法通过Pub Med、Cochrane CENTRAL、Sino Med收集有关临床干预试验文献,产品信息在某购物网站,健康教育信息在百度搜索引擎收集,教材在北京大学医学部图书馆检索并提取。结果合成598人、37组临床试验数据,维生素D补充前后,钙吸收率变化0.421%(95%CI:-1.875~1.033)。14/30产品功效宣称、14/97网页内容传播"不补充维生素D钙不能很好吸收"的信息,51部营养学教材均只陈述"维生素D促进钙吸收"的内容。结论现有临床干预试验证据说明维生素D补充剂对钙吸收率没有影响,产品功效宣称和网上健康教育有关信息存在不科学的误导,营养教材有关知识陈旧。
[Abstract]:Objective to synthesize the evidence based on the results of clinical trials, and analyze the scientific nature of vitamin D promoting calcium absorption in relevant health products, online information and related professional textbooks. Methods the clinical intervention trials were collected through Pub Med#en1# Cochrane CENTRALN Sino Med. Product information was collected in a shopping website, health education information was collected in Baidu search engine, textbooks were retrieved and extracted from Peking University Medical Department Library. Results 598 patients received 37 groups of clinical trial data before and after vitamin D supplementation. Calcium absorptivity changes the efficacy of 0.421%(95%CI:-1.875~1.033).14/30 products claims that 14 / 97 web pages disseminate information that "calcium can't be absorbed very well without vitamin D supplementation." 51 nutrition textbooks all state only the contents of "vitamin D promotes calcium absorption". The evidence in the bed intervention trial showed that vitamin D supplementation had no effect on calcium absorption. Product efficacy claims and online health education related information is unscientific misleading, nutrition textbooks about the old knowledge.
