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. We hypothesize that vitamin D supplementation reduced the progression of pre-diabetes [impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT)] in a dose-dependent manner compared to placebo administration. prior to resubmitting our NIH grant, we wish to obtain pilot data to determine if a) using a monthly dose of liquid vitamin D3) , we are able to raise serum 25-OHD into the upper normal range and 2) whether this effects glycemic indices, including fasting glucose levels and calculations o insulin sensitivity and insulin secretion. Aim: To treat primarily ethnic/racial minority patients with hypovitaminosis D [vitamin D levels less than 30 ni/mL] and pre-diabetes with placebo or two doses of vitamin D3 (300,000 IU of liquid Vit D on day 1 and day 30) designed to raise serum 25-Ohd into the upper normal range. Outcomes will include changes from baseline in fasting glucose levels and estimates of insulin sensitivity and insulin secretion.

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。子项目和 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。 我们假设，与安慰剂给药相比，维生素D补充剂以剂量依赖性方式降低了糖尿病前期[空腹血糖受损（IFG）和/或糖耐量受损（IGT）]的进展。在重新提交我们的NIH拨款之前，我们希望获得试验数据以确定a）使用每月剂量的液体维生素D3），我们是否能够将血清25-OHD提高到正常范围的上限，和2）这是否影响血糖指数，包括空腹葡萄糖水平和胰岛素敏感性和胰岛素分泌的计算。 目的：主要用安慰剂或两剂维生素D3（第1天和第30天300，000 IU液体维生素D）治疗维生素D缺乏症D [维生素D水平低于30 mg/mL]和糖尿病前期的少数民族/种族患者，旨在将血清25-Ohd升高至正常范围上限。结果将包括空腹血糖水平较基线的变化以及胰岛素敏感性和胰岛素分泌的估计值。
