长期植入型避孕药可能会导致体重增加问题

近日,90后夫妇生育10个孩子的采访引发了网友的广泛关注,大家也对于有关节育措施利弊问题开展了广泛讨论。

想必大家都知道,较为常见的节育措施有结扎、上环、避孕药、避孕套等。在西方国家,人们常采用口服避孕药的方式孕药,约有40%女性会口服短效避孕药,而在我国,大家主要采用避孕套方式避孕。

我国女性不愿使用避孕药方式避孕的主要原因是担心口服避孕药会带来副作用,而针对于避孕药可能带来的副作用问题,国内外有学者正在进行相关研究。

近日,来自美国科罗拉多大学医学院的学者对植入型避孕药的副作用进行了研究后发现,长期植入型避孕药可能会导致体重增加问题。

该项研究发表在Contraception上,其题目为Aaron Lazorwitz et al. An exploratory analysis on the influence of genetic variants on weight gain among etonogestrel contraceptive implant users,中文翻译为《植入型依托孕烯避孕药使用人群遗传因素对体重增加影响的探索性分析》。

本项研究主要是想确定与体重增加、个体遗传因素以及依托孕烯(etonogestrel)避孕药使用间的关系。依托孕烯是一种抑制排卵的孕激素,将依托孕烯避孕植入物植入皮肤,可以实现有效节育。

通过对使用依托孕烯避孕植入物的健康育龄父母的体重变化以及遗传基因进行分析,研究人员试图寻找它们之间的关联性。

研究人员对276名妇女从植入避孕药到研究期间的客观体重变化进行统计,结果表明,参与者平均使用药物27个月后,其平均体重增加了7磅(约6.3斤),有近四分之三的妇女出现体重增加现象。

研究人员通过进一步研究发现,雌激素受体1(ESR1)基因并不会直接导致肥胖问题,但在生理上,由孕激素介导的ESR1与体重增加间存在一定联系。

某些女性的ESR1与体重显着增加有关,拥有ESR1 rs9340799两种变体类型基因的妇女使用植入型避孕药后,其体重增加均在30磅(27斤)以上。

论文作者亚伦·拉佐维茨博士(Aaron Lazorwitz)说:“长久以来,女性一直在说这种节育方式会导致体重增加问题,但许多医生却根本没有认真对待这一问题。”“当使用这些药物时,必须更好地了解个体遗传特性如何提升女性体重增加的风险。”

研究人员表示,基于本项研究对妇女健康方面的理解,未来可以提供个性化的避孕咨询,以减少激素相关副作用的发生率,提高患者的满意度,减低女性未来的健康风险。

当前,尚无办法确定哪些群体在使用此类药物时会导致体重增加问题。研究人员建议,医疗部门可以向使用者提供体重增加风险的提示,或建议采用非激素形式的节育方式。

所以,做个好男人,别让对象吃苦,最好慎用这种避孕药哦。
