孕妇血清Hcy水平与子代认知能力相关性的队列研究

孕妇血清Hcy水平与子代认知能力相关性的队列研究摘要：

目的：研究孕妇血清高分子Hcy水平与子代认知能力的相关性，探讨血清Hcy水平是否对子代认知能力的发展产生影响，为孕妇保健提供科学参考。

方法：我们选取河南省某医院的270名产妇为研究对象，检测孕妇血清高分子Hcy水平，并对其子代进行智能测试。采用多元线性回归模型对数据进行分析。

结果：研究发现，孕妇血清Hcy水平与子代认知能力之间存在显著的负相关（P<0.05），即孕妇血清Hcy水平越高，子代认知能力表现越差。特别是在孕期中、晚期检测到的血清Hcy水平与子代认知能力的相关性更为显著。

结论：孕妇血清高分子Hcy水平与子代认知能力存在相关性，血清Hcy水平对子代认知能力的发展具有一定的影响。孕期应重视血清Hcy水平的监测，并通过合理的饮食和营养补充来降低孕妇的血清Hcy水平，保障胎儿的智能发育。
