避孕药能预防运动性膝盖损伤

2016-03-21 佚名 睿医

德克萨斯大学医学分校的研究人员发现,口服能降低并稳定雌激素水平的避孕药的女性膝盖严重受伤的概率比其他女性小。这一研究成果已经发表在《体育运动药物科学》上,这个期刊是美国运动医学协会的官方杂志。 女运动员前交叉韧带或ACL受伤的概率比男运动员高1.5倍到2倍。ACL是连接膝盖上下两部分的韧带。ACL损伤会导致严重的运动损伤甚至会改变运动员的职业生涯。ACL损伤后恢复运动率在足球运动员中只有49%。

德克萨斯大学医学分校的研究人员发现,口服能降低并稳定雌激素水平的避孕药的女性膝盖严重受伤的概率比其他女性小。这一研究成果已经发表在《体育运动药物科学》上,这个期刊是美国运动医学协会的官方杂志。

女运动员前交叉韧带或ACL受伤的概率比男运动员高1.5倍到2倍。ACL是连接膝盖上下两部分的韧带。ACL损伤会导致严重的运动损伤甚至会改变运动员的职业生涯。ACL损伤后恢复运动率在足球运动员中只有49%。而且,这种损伤会导致终身的膝盖不稳定、步态改变和早发型关节炎。

研究人员利用全国保险索赔与处方数据库中15到19岁间23428名年轻女性的数据,发现服用避孕药的ACL膝盖损伤的女性需要矫型手术的概率比同龄未服用避孕药的女性低。

研究人员曾认为雌性激素会使ACL减弱而导致女性ACL更容易受伤。前期的一项研究发现多数女性的ACL损伤都发生在雌激素水平较高的经期。

本研究的第一作者博士生Aaron Gray表示,避孕药能使女性的雌激素水平保持较低且更稳定,这就可能避免周期性的ACL减弱。考虑到这一点,我们研究了口服避孕药能否避免需要矫型手术的严重ACL损伤的发生。

需要ACL重建手术女性最多的年龄段是15-19岁,这些女性如果服用避孕药就会降低22%膝盖ACL损伤的风险。

Gray认为青春期的激素变化可能导致这个年龄段女性ACL损伤较多的原因。青春期女性的雌激素会突然大幅上升,同时腿部也会生长骤增。生长骤增后,这些青少年需要一段时间才能开始协调地运用突然长长的四肢。目前,年轻运动员因为各种原因服用避孕药,如为了月经周期更规律,周期间隔更长等。如果有进一步前瞻性研究,为了降低受伤率也可能成为女运动员服用避孕药的原因之一。
