近期有研究称补钙并不能增加骨健康,那还要补钙么?这些研究的具体内容是什么呢?

因为钙是骨健康的基石,多年来,老年人被建议增加膳食钙的摄入量,或者被建议补充钙片。同时,由于没有维生素D人体不能吸收钙,因此维生素D通常作为补钙的搭档被推荐补充。近期有研究者对于这个经验性观点,进行了系统回顾。以探究补钙或者补充维生素D究竟能不能预防骨折,使我们的骨骼更健康,但是结果却出乎意料!这些研究,有2项发表在英国医学期刊(BMJ)上,还要一项发表在JAMA Intern Med上。1.BM

因为钙是骨健康的基石,多年来,老年人被建议增加膳食钙的摄入量,或者被建议补充钙片。同时,由于没有维生素D人体不能吸收钙,因此维生素D通常作为补钙的搭档被推荐补充。



近期有研究者对于这个经验性观点,进行了系统回顾和对照临床试验。以探究补钙或者补充维生素D究竟能不能预防骨折,使我们的骨骼更健康,但是结果却出乎意料!这些研究,有2项发表在英国医学期刊(BMJ)上,还要一项发表在JAMA Intern Med上。

1.BMJ上的两项关于补钙的研究:

两项研究是同一个在新西兰的研究小组进行的。下面是两个研究的设计与结果:



(1)钙与骨密度(BMD):研究共纳入了2013-07至2014-09间的59个随机对照试验,研究对象均为50岁以上人群,主要钙来源为膳食与补钙剂/钙片(不管有没有VD),以腰椎、全髋关节、股骨颈、全身或前臂BMD作为研究观察指标。纳入的文献中,有15个(n=1533)研究的膳食钙与骨密度的关系,有51g个(n=12 257)研究的补钙剂/钙片与骨密度的关系。

经过Meta分析,研究人员发现:不管是通过膳食还是补钙剂/钙片(不管含不含VD)补钙,均只能小幅度非渐进性的增加骨密度(BMD)(增加0.6-1.8%之间),甚至膳食钙对前臂骨密度几乎没有影响。这远远达不到人们对补钙的期许。

(2)钙与骨折:研究者检索了2013-07至2014-09间Ovid Medline, Embase, PubMed等数据库,以及系统回顾相关参考文献中关于补钙与骨折的研究。纳入了年龄> 50岁,通过膳食钙、牛奶或乳制品的摄入、或补钙剂(单独或联合VD)补钙,对研究对象骨折风险影响的相关文献。纳入文章中关于饮食补钙有2个随机对照试验(n=262),44个队列研究共计50次试验,涉及膳食钙(n = 37)、牛奶(n = 14)、或奶制品摄入补钙(n = 8)与骨折风险的探究。

研究结果显示,大多数研究报道膳食钙摄入和骨折风险之间没有联系;大多数研究报道也没有发现牛奶和奶制品的摄入补钙可以减少骨折风险,预防骨折。在26个随机对照试验中,数据表明补钙剂可以减少全身骨折风险和脊柱骨折风险,但是不减少髋部骨折风险和前臂骨折风险。只有在一个对虚弱的老年妇女(低膳食钙摄入量和低维生素D浓度)的试验发现,补钙剂可以显著减少骨折的风险。

2.JAMA Intern Med上关于补充维生素D的研究:



这是一个
在威斯康星州麦迪逊市的单中心、
随机、双盲、安慰剂对照的临床试验,在近四年的试验及随访时间里,共230名75岁及以下的绝经后女性参与了此研究,这些参与者
均没有骨质疏松
,基线25(OH)D水平为14至27ng/mL。参与者随机分为三组,分别接受安慰剂、低剂量和高剂量维生素D3后,评估他们的总体钙吸收的1年变化、骨密度、计时起立-行走和5次坐立试验、以及肌肉质量的1年变化。

研究人员发现:在基线的钙吸收进行控制后,高剂量组的钙吸收增长了1%(10mg/d),但在低剂量组降低了2%(P=0.005 VS 高剂量组),安慰剂组下降了1.3%(P=0.03 VS 高剂量组)。研究人员在脊柱变化、平均总髋、平均股骨颈、或全身骨密度、骨小梁分数、肌肉质量、计时起立-行走和5次坐立测试成绩方面没有发现组间变化。同样地,研究人员在跌倒的次数、跌倒人数、体力活动、或功能状态方面也没有发现任何组间差异。



三个研究表明:无论是膳食钙还是钙剂,只能极小幅度的增加骨密度,可是这不足以预防骨折的发生,同时,高剂量的维生素D3虽然增加了钙的吸收,但效果不大,并没有转化为对骨密度、肌肉功能、肌肉质量、或跌倒有益的影响。

那么,我们还要不要继续补钙或者补充维生素D呢?

首先,这3项研究中的参与者都是没有骨质疏松的健康老年人。因此,这3个研究只能说明对于大多数正常人群,补钙或者补充维生素D对骨强度和骨骨折的几率几乎没有影响。

其次,我们每天需要大约700毫克钙,其实,膳食钙的良好来源(包括乳制品,如牛奶,奶酪和酸奶;油性鱼类,如沙丁油鱼和凤尾鱼;或坚果如杏仁和芝麻等)已经足够我们日常的基本需求了。再者,之前有研究表明,钙补充剂可以对部分人群产生包括便秘和肾结石在内的副作用,而且钙补充剂也有增加心脏病发作的几率。因此,对于没有骨质疏松的健康人群,可以尝试通过丰富的膳食补钙,但是最好少服用钙剂。

再者,BMJ的两项队列研究,存在队列研究本身的不足和发表偏倚,同时,
JAMA Intern Med上的研究存在样本量过小(n=230)的不足。因此,临床医生应该谨慎地看待3项研究的研究结果。



总而言之,对于没有骨质疏松症或者缺乏相关营养元素的健康人,补钙或者维生素D貌似只能增加花销。而对于有骨质疏松症,或者是缺乏这些营养元素的患者,临床医生应该建议他们继续服用钙和维生素D补充剂。

BMJ:补钙只能小幅度增加骨密度(META分析)

该荟萃分析表明,不管是通过膳食还是补钙剂/钙片(不管含不含VD)补钙,均只能小幅度非渐进性的增加骨密度(BMD),不大可能让骨骼变得人们期许的那么坚强。

BMJ:还在妄想通过补钙预防骨折吗?

补钙并不能有效预防骨折,不管是通过饮食、牛奶,还是钙片等保健品,不管有没有含VD,均不能有效预防骨折。
