这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目及 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 具体目标 目标1：评估一家医院初级保健门诊健康婴幼儿的隐性维生素D缺乏症和佝偻病的患病率。 目标二：确定该样本中维生素D缺乏症和佝偻病的风险因素（母亲和儿童），包括年龄、营养、补充剂以及年龄和营养因素之间的相互作用。 目的#3：评价两种不同方案治疗维生素D缺乏症和佝偻病的疗效。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Specific Aims Aim#1: To evaluate the prevalence of occult vitamin D deficiency and rickets among a clinic sample of healthy infants and toddlers at a hospital-based primary care clinic. Aim #2: To identify risk factors (both maternal and child) for vitamin D deficiency and rickets within this sample, including age, nutrition, supplementation, and interaction between age and nutritional factors. Aim #3: To evaluate the efficacy of two different regimens for the treatment of vitamin D deficiency and rickets.
