Vitamin D is a fat-soluble vitamin that performs an important role in calcium homeostasis and bone metabolism and also affects many other cellular regulatory functions outside the skeletal system. Vitamin D requirements may vary by individual; thus, no one serum vitamin D level cutpoint defines deficiency, and no consensus exists regarding the precise serum levels of vitamin D that represent optimal health or sufficiency.
To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on screening for vitamin D deficiency, including the benefits and harms of screening and early treatment.
Community-dwelling, nonpregnant adults who have no signs or symptoms of vitamin D deficiency or conditions for which vitamin D treatment is recommended.
The USPSTF concludes that the overall evidence on the benefits of screening for vitamin D deficiency is lacking. Therefore, the balance of benefits and harms of screening for vitamin D deficiency in asymptomatic adults cannot be determined.
The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for vitamin D deficiency in asymptomatic adults. (I statement).
维生素 D 是一种脂溶性维生素,在钙稳态和骨骼代谢中发挥着重要作用,也影响骨骼系统以外的许多其他细胞调节功能。个体的维生素 D 需求可能不同;因此,没有一个血清维生素 D 水平切点定义为缺乏,也没有关于代表最佳健康或充足的血清维生素 D 水平的确切共识。
为了更新其 2014 年的建议,美国预防服务工作组 (USPSTF) 委托对维生素 D 缺乏症的筛查进行了系统评价,包括筛查和早期治疗的益处和危害。
无维生素 D 缺乏或有维生素 D 治疗推荐指征的症状或体征的社区居住、非孕妇成年人。
USPSTF 得出的结论是,缺乏关于筛查维生素 D 缺乏症益处的总体证据。因此,无法确定在无症状成年人中筛查维生素 D 缺乏症的益处和危害之间的平衡。
USPSTF 得出的结论是,目前的证据不足以评估在无症状成年人中筛查维生素 D 缺乏症的利弊平衡。(I 声明)。
