据来自奥克兰大学的一项研究证实,婴儿的母亲在怀孕期服用维生素D补充剂的话,婴儿不太可能患呼吸道感染。

该研究显示,相较于安慰剂组,孕期孕妇补充维生素D后,婴儿发生呼吸道感染的比例较小。这项研究结果最近发表在杂志Acta Paediatrica上。

本次临床试验的主要目的,以确定维生素D的剂量对于怀孕期间孕妇是必要的,以防止婴儿维生素D不足。

Grant博士说,仔细而彻底的审查基层医疗记录后,研究人员能够确定在妊娠后半期的母亲,每天给予维生素D补充剂,然后他们的婴儿年龄在6个月时,较小出现任何呼吸道感染,这一效应持续长达18个月。这一有趣的效果在补充维生素D被中断后会持续下去。

通过在怀孕期间开始服用维生素D,即经常服用日常剂量的维生素D,而不是更大剂量的维生素D,能够安全有效地改善出生婴儿的维生素D水平。

Grant博士说,研究团队正专注于确定维生素D补充剂如何可能导致这种有益的影响。在中断补充剂后,维生素D的保护作用依然存在,这表明维生素D可导致儿童的免疫系统作出一些调整,导致他们呼吸道不容易受到病毒感染或一旦感染后不易发生严重不适症状。

JCEM:精神分裂?有可能是缺乏维生素D

近日,刊登在国际杂志Journal of Clinical Endocrinology & Metabolism上的一篇研究论文中,来自伊斯法罕大学的研究人员通过研究表明,维生素D缺失的个体患精神分裂症的风险是正常个体(维生素D水平充足)的两倍。维生素D可以帮助机体吸收钙质,其同样对于骨骼和肌肉的健康也至关重要,正常情况下皮肤暴露于太阳光后会产生维生素;人们通过食物比如牛奶等获得的维生素量

JCEM:维生素D是体外授精的关键

目前,一项大型前瞻性横断面研究结果显示,血清维生素D水平可影响体外授精成功几率。8月14日在线发表于the Journal of Clinical Endocrinology and Metabolism杂志的一项研究报告表明,行体外授精的患者其血清维生素D水平高于20 ng/mL者,获得3个或以上高质量胚胎、胚胎成功着床以及临床受孕的几率增高。 来自意大利米兰的Paffoni教授等人发

Prostate:炎症或是维生素D和前列腺癌发病之间缺失的关键环节

近日,来自科罗拉多大学癌症中心的研究人员通过研究发现,炎症或许是连接维生素D和前列腺癌发病之间的一个关键点,相关研究发表于国际杂志The Prostate上。文章中,研究者指出,被维生素D上调的基因GDF-15或许在由炎症驱动的人类前列腺癌组织样本中是明显缺失的。 James R. Lambert博士表示,当服用维生素D并且作用于前列腺癌细胞时,维生素D就会抑制癌细胞的生长,但这并不能证明其

Diabetes Care:维生素D在糖尿病前期并不能改善血糖指数

2014年7月4日讯 /生物谷BIOON/--根据发表在Diabetes Care杂志上的一则最新研究证实:补充维生素D似乎并没有改善糖尿病前期个体的血糖指数或心血管危险因素。 挪威大学科学家随机分配511空腹血糖异常(IFG)或糖耐量异常(IGT)者到维生素D3或安慰剂组。一年后,研究人员观察到维生素D组和安慰剂组之间糖代谢,胰岛素分泌或胰岛素敏感性无显著差异。各组的血压或血清高敏C-反应蛋

Am J Clin Nutr:维生素D或并不会阻断心脏病和中风的发生

近日,来自东安格利亚大学的研究人员通过研究表明,服用维生素D片并不能避免心脏病和中风的发生,相关研究刊登于国际杂志Am J Clin Nutr上。 近来有研究揭示维生素D水平和患多发性硬化症、糖尿病、精神分离症等病症发病数量增加直接相关;此前研究中研究人员发现,维生素D水平较低的个体更有可能患心血管疾病,而本文研究则发现维生素D的补充并不会降低个体患心血管疾病的风险,然而其却可以保护老年个体抵御

Lancet Diab & Endo:血循环25[OH]D浓度与患2型糖尿病风险的关系:孟德尔随机化研究

25[OH]D是维生素D的一种状态标志,研究已发现血循环中低的25[OH]D浓度与增加的2型糖尿病患病风险密切相关,但这种关系是否有因果关联目前还不是很清楚。为了研究25[OH]D浓度与2型糖尿病患病风险的因果关系,来自英国剑桥大学代谢科学研究所的科学家们根据多个欧洲裔人群数据源,包含患2型糖尿病与未患数据,利用单核苷酸多态性进行了一项大数据孟德尔随机化分析(研究共纳入28144病例数/76344
