In a study of 185 elderly living in assisted care and 192 frail aged living in the community in the Sydney metropolitan area, nursing home residents were found to be at a 3-fold and hostel dwellers at a 2-fold risk of Vitamin D [25(OH)D] deficiency (<25 nmol/L) compared to self care residents. Middle Eastern people were found to be at 4-fold risk and Vietnamese a 3-fold risk of deficiency compared to their Australian counterparts. In recently arrived Chinese immigrants, Vitamin D deficiency, was found in 28%, and marginal levels (<37 nmol/L) in 60%, compared to the 34 and 76% found in our nursing home population, and 25 and 57% in hostel care residents. Of the Middle Eastern elderly, 58% were deficient and 83% marginal; although only 18% of Vietnamese were deficient, 68% had marginal Vitamin D status. Other factors associated with Vitamin D deficiency were mobility and sun exposure in assisted care, and low dietary Vitamin D and calcium intake, reduced exercise levels and high % body fat levels in the immigrant groups.
在一项针对悉尼都会区185名住在辅助护理机构的老年人以及192名住在社区的体弱老年人的研究中，发现与自理的居民相比，养老院居民维生素D[25(OH)D]缺乏（<25 nmol/L）的风险是其三倍，宿舍居住者的风险是其两倍。与澳大利亚同龄人相比，中东人缺乏维生素D的风险是其四倍，越南人是其三倍。在最近抵达的中国移民中，28%的人维生素D缺乏，60%的人处于边缘水平（<37 nmol/L），相比之下，我们养老院人群中的这一比例分别为34%和76%，宿舍护理居民中的比例为25%和57%。中东老年人中，58%缺乏维生素D，83%处于边缘水平；虽然只有18%的越南人缺乏维生素D，但68%的越南人维生素D水平处于边缘状态。与维生素D缺乏相关的其他因素包括辅助护理机构中的行动能力和日照情况，以及移民群体中膳食维生素D和钙摄入量低、运动水平降低和体脂百分比高。
