Tob Control:二手烟暴露或可导致女性不孕不育及绝经期提前

2015-12-17 MedSci MedSci原创

既往一些研究表明,女性不孕及自然绝经年龄与烟草的消耗有关,但是却很少有研究探讨二手烟(SHS)与女性不孕以及自然绝经年龄之间的关系。本研究旨在探究终身烟草暴露(主动吸烟和SHS)与女性不孕和自然绝经年龄(50岁以前)之间的关联。使用妇女健康倡议观察性研究(WHI OS)为这个问题的分析提供了全面的、量化的二次数据。

既往一些研究表明,女性不孕及自然绝经年龄与烟草的消耗有关,但是却很少有研究探讨二手烟(SHS)与女性不孕以及自然绝经年龄之间的关系。本研究旨在探究终身烟草暴露(主动吸烟和SHS)与女性不孕和自然绝经年龄(50岁以前)之间的关联。使用妇女健康倡议观察性研究(WHI OS)为这个问题的分析提供了全面的、量化的二次数据。

研究共纳入了93676名年龄在50-79岁的绝经女性,收集其吸烟,生育情况以及自然绝经年龄的数据。使用校正后的多变量回归模型来估计主动吸烟与SHS暴露水平的OR值及95%可信区间,并根据主动吸烟和二手烟暴露来检测女性不孕及绝经年龄的趋势。

总体而言,15.4%的88732名用于不孕分析的女性符合标准。45%的79690名用于分析自然绝经年龄(50岁以前)的女性符合标准。主动吸烟者总的OR为1.14(95% CI 1.03-1.26),不孕;与不吸烟女性相比,主动吸烟女性总的OR为1.26(95% CI 1.16-1.35),提前进入绝经期。不吸烟但是二手烟暴露水平最高的女性调整后的OR为1.18(95% CI 1.02-1.35),不孕;OR为1.18(95% CI 1.06-1.31),提早进入绝经期。与不吸烟但是暴露于二手烟的女性相比,主动吸烟的女性绝经时间(平均49.4岁)要提前21.7个月 ,较暴露于最高水平SHS中的女性提前13个月。

总而言之,该研究表明,主动吸烟和二手烟的暴露均可增加女性不孕不育的发生风险,还存在提前自然绝经(<50岁)的发生风险。
