Pediatrics:孕妇缺乏维生素D可影响后代牙齿发育

2014-05-16 desperado-c 丁香园

最近,加拿大的一项前瞻性队列研究发现,母亲产前维生素D水平较低与婴幼儿龋齿风险增加有关。 来自温尼伯曼尼托巴大学的Robert J. Schroth博士及其同事在文章中写道,宫内维生素D缺乏与胎儿牙釉质发育不全有关,并从而可增加其龋齿风险。这在妊娠中期尤为重要,因为妊娠中期是牙齿开始钙化的主要时期。 最初参加这项研究的207例女性受试者产前平均25羟维生素D(25OHD)水平为48nmol/l

最近,加拿大的一项前瞻性队列研究发现,母亲产前维生素D水平较低与婴幼儿龋齿风险增加有关。

来自温尼伯曼尼托巴大学的Robert J. Schroth博士及其同事在文章中写道,宫内维生素D缺乏与胎儿牙釉质发育不全有关,并从而可增加其龋齿风险。这在妊娠中期尤为重要,因为妊娠中期是牙齿开始钙化的主要时期。

最初参加这项研究的207例女性受试者产前平均25羟维生素D(25OHD)水平为48nmol/l。其中,大约三分之一的受试者(67例,32.5%)伴有维生素D缺乏(定义为25OHD<35nmol/l),24例受试者(12%)的维生素D处于最佳水平(≥75nmol/l)。

在135例返回医院复诊的婴儿中,研究者寻找有无乳牙腐烂和釉质龋。受试者的平均年龄为16个月,中位数年龄为19个月。

Schroth博士等发现,复诊婴儿中22%有牙釉质发育不全。当龋齿定义局限于成洞的釉质损伤时,接近四分之一婴儿(23%)在童年早期就出现龋齿。当将釉质白斑病变也纳入龋齿定义时,超过三分之一的婴儿在童年早期就出现龋齿。

当龋齿定义局限于成洞的釉质损伤时,童年早期有龋齿的婴儿,其母亲产前25OHD浓度低于无龋齿婴儿的母亲,但是,当将釉质白斑病变也纳入龋齿定义时,两者间的25OHD浓度没有显著差异。

使用维生素D缺乏和最佳水平的切点对25OHD浓度进行分组,发现不同组别孕妇的25OHD水平与其后代童年早期龋齿风险没有明显相关性。但是,Poisson回归显示婴儿龋齿的平均数量与母亲产前25OHD水平呈显著负相关。

校正家庭收入、就业状况、婴儿喂养方法、季节和婴儿口腔卫生习惯后,牙釉质发育不全、婴儿年龄和较低的25OHD水平与童年早期龋齿风险呈显著独立相关。

Schroth博士总结到,“应进一步调查改善牙齿形成期间的营养状况,是否能作为降低龋齿风险的一个潜在治疗策略。”Schroth博士还建议孕妇在妊娠早期就应采取预防措施改善营养状态,无论是通过增加膳食摄入,还是补充维生素D。”

来自美国加利福尼亚州旧金山市阳光、营养与健康研究中心的William B. Grant博士长期以来一直支持维生素D补充治疗。Grant博士告诉路透社健康版,“所有的孕妇和哺乳期妇女每天都需摄入4000–5000IU的维生素D3。这对妊娠结局有很多益处,包括降低妊娠糖尿病、呼吸道和其他部位感染、早产、先兆子痫的风险,以及减少维生素D缺乏对胎儿的不良影响,包括很可能出现的自闭症等在内的出生缺陷。”

Grant博士同时指出,“近来有大量关于维生素D的宣传,而且,与25OHD水平有关观察性研究与随机对照研究的结论往往不一致。这些差异的原因是,大多数的随机对照研究在普通人群中进行,研究人群的平均25OHD水平在20–30ng/ml之间。随机对照研究多根据药物治疗模型设计,这种试验仅能提供药品的信息,而且存在线性剂量效应关系。而且研究中关于维生素D的假设都不正确。

不久前,来自美国华盛顿大学的Philippe P. Hujoel博士回顾了已发表的临床对照试验中维生素D与龋齿的关系。Hujoel博士告诉路透社健康版,“在很久以前,美国国家科学院、美国医学会和美国牙科学会就推荐使用维生素D补充治疗预防龋齿。令人吃惊的是,关于维生素D预防龋齿作用这一常识竟然会逐渐被大部分人所遗忘。

然而,Hujoel博士不建议在妊娠期进行维生素D补充治疗。他指出,“当前,关于妊娠期维生素D补充治疗获益大于风险的证据尚不充分。”Hujoel博士建议在妊娠期通过自然途径维持适当的维生素D水平,如享受阳光,选择富含维生素D的食物,例如野生三文鱼、黄鳍金枪鱼、蘑菇和鸡蛋,而不是通过服用维生素D制剂。此外,减少碳水化合物摄入也会降低机体维生素D需求量。

Hujoel博士总结到,“这项研究带给医师最主要的信息是,如果孕妇维生素D水平欠佳,在胎儿发育过程中牙齿最先受累,而且,这种损伤是不可逆的。”

JCEM:维生素D可改善肿瘤病人预后

4月29日,国际学术期刊《临床内分泌代谢杂志》(Journal of Clinical Endocrinology & Metabolism)以Special Feature形式在线发表了营养所王慧研究组的论文,同时美国内分泌学会在华盛顿进行新闻发布,受到各国媒体关注。该研究表明诊断时体内25-羟维生素D水平较高的肿瘤病人预后较好。 维生素D是人体必需的脂溶性维生素,属固醇类衍生物,主要

BMJ:维生素D的健康益处仍有待确定

本周发表在BMJ上的两项大规模meta分析声称(BMJ:维生素D或能降低死亡风险),多种关于维生素D健康益处的主张是没有根据的。Kmietowicz对这两项研究及同期发表的评论进行了报道。 研究人员认为关于维生素D的益处不能得出通用的结论,仍需要深入研究和设计良好的临床试验。在一篇社论中,评论员说道,除了那些具有骨相关性疾病的患者外,医生应当停止为无症状患者处方昂贵的25-羟维生素D。 在第一

BMJ:维生素D或能降低死亡风险

维生素D具有广泛的抗炎和免疫调节作用,低浓度维生素D被认为是死亡的潜在决定因素。然而,维生素D缺乏与心血管疾病、癌症和其它疾病死亡的相关性仍不确定。因此,为了评价在各种情况下,血液生物标志物和维生素D补剂与心血管、癌症或其它疾病死亡的相关性程度。 来自剑桥大学公共卫生和初级护理部的Chowdhury博士等进行了一项研究,发现补充维生素D显著降低死亡率。文章发表在2014年4月1日的BMJ上。

Diabetologia:维生素D缺乏与1型糖尿病疾病进展无关
