2017年9月,发表在《Hum Reprod》上的一项队列研究,研究了在经历ART的女性中,治疗前摄入酒精和咖啡因与不孕治疗结局的相关性。研究结果表明:不孕治疗开始前一年内低至中度酒精和咖啡因摄入对ART中间或临床结局没有不良作用。

2017年9月,发表在《Hum Reprod》上的一项队列研究,研究了在经历ART的女性中,治疗前摄入酒精和咖啡因与不孕治疗结局的相关性。研究结果表明:不孕治疗开始前一年内低至中度酒精和咖啡因摄入对ART中间或临床结局没有不良作用。

研究问题:在经历ART的女性中,治疗前摄入酒精和咖啡因是否与不孕治疗结局相关?

答案总结:生殖治疗前1年内低至中度酒精和咖啡因摄入与ART结局无关。

已知内容:许多研究发现酒精和咖啡因摄入与不孕相关。然而,与不孕治疗结局相关的数据很少且不一致。

研究设计、大小、持续时间:研究人员从正在进行的环境和生殖健康队列研究(2006-2016)中纳入300名女性(493例ART疗程)。

受试/材料、环境和方法:采用一个经验证的食品频率调查问卷回顾性评估治疗前酒精和咖啡因的摄入。从电子病例中提出ART的中间和临床终点。采用考虑每名女性多个ART疗程的一般线性混合模型以及随机截距评估与ART结局的关联(校正年龄、BMI、吸烟状态、不孕诊断、病例类型、种族、饮食模式、以及卡路里、维生素B12和叶酸的摄入)。

主要结果和机会角色:治疗前酒精和咖啡摄入量的中位数(范围)分别是5.6(0.0-85.8)g/日和124.9(0.3-642.2)mg/日。在治疗前酒精摄入类型递增分组的女性中,女性最初疗程活产的校正百分比(95%CI)分别为:未摄入者为34%(20,52%),12.1-24 g/日是42%(31,55%),>24 g/日是41%(22,63%)(P,趋势-0.87)。在咖啡因摄入类型递增分组的女性中,女性最初疗程活产的校正百分比(95%CI)分别为:<50 mg/日是46%(36-57%),50.1-100 mg/日是44%(29,60%),100.1-200 mg/日是42%(31,53%),200.1-300 mg/日是40%(28,53%),>300 mg/日是40%(21,63%)(P,趋势=0.34)。当评估酒精的特殊类型和咖啡因饮料时,未观察到与ART治疗结局相关。

局限性、谨慎的原因:由于本研究为观察性研究,而不能排除其他饮食和生活方式的残留混杂。目前仍不清楚这些结果如何推广到无ART辅助怀孕的女性。

结果更广泛的含义:研究人员的结果提供了保证,即不孕治疗开始前一年内低至中度酒精(例如,≤12 g/日)和咖啡因(例如,<200 mg/日)摄入对ART中间或临床结局没有不良作用。

研究基金/竞争利益:作者获得国家健康研究院(NIH)基金ES022955,R01ES009718,R01ES000002,P30DK46200和L50-HD085359。无利益冲突。
