Vitamin D deficiency is gaining increased attention nationally. Recent clinical cases suggest that this condition is a significant problem in local refugee populations. The Sioux Falls Health Department recently implemented a policy of screening and treating all new refugees as part of the new refugee examinations at Falls Community Health Center.
Data from this screening during the first nine months of 2009 were reviewed and analyzed for prevalence of hypovitaminosis D in this population. Results from a total of 157 individuals were included in this study.
Two percent of this population had initial calcidiol levels below the detection threshold. Six percent were severely deficient, defined as <15 ng/mL, and 58 percent were mildly deficient (15-32 ng/mL). Only 36 percent had levels above 32 ng/mL, considered adequate for bone health, with a mere 1 percent showing optimal levels of > 50 ng/mL.
Hypovitaminosis D represents a significant public health issue among recent immigrants in Minnehaha County, S.D., and warrants aggressive attention by both primary care and public health professionals.
维生素D缺乏在全国范围内日益受到关注。近期临床病例表明，这种情况在当地难民群体中是一个重大问题。苏福尔斯市卫生部门最近实施了一项政策，即在瀑布社区健康中心对所有新难民进行筛查和治疗，作为新难民检查的一部分。
对2009年前九个月此次筛查的数据进行回顾和分析，以了解该人群维生素D缺乏症的患病率。本研究纳入了总共157人的结果。
该人群中有2%的人最初的骨化二醇水平低于检测阈值。6%的人严重缺乏，定义为低于15纳克/毫升，58%的人轻度缺乏（15 - 32纳克/毫升）。只有36%的人水平高于32纳克/毫升，这被认为对骨骼健康足够，仅有1%的人显示最佳水平大于50纳克/毫升。
维生素D缺乏症是南达科他州明尼哈哈县近期移民中的一个重大公共卫生问题，值得初级保健和公共卫生专业人员积极关注。
