摘要 目的分析孕期甲状腺激素水平与新生儿出生体重的关系。方法选择2014—2015年在舟山市妇幼保健院进行孕期保健的孕妇为研究对象,检测甲状腺激素水平并进行随访调查,分析孕妇甲状腺激素水平与新生儿出生体重的相关性。结果孕早、中和晚期促甲状腺素(TSH)水平[M(QR)]分别为1.13(1.29)、1.43(1.18)和1.87(1.72)μIU,游离三碘甲腺原氨酸(FT3)水平分别为4.47(0.95)、4.25(0.94)和4.07(0.89)pmol/L,游离三碘甲腺素(FT4)水平分别为11.97(4.22)、10.43(3.71)和9.00(2.31)pmol/L;随着孕周增加,TSH水平上升,FT3、FT4水平下降(均P<0.01)。甲状腺激素按孕周标准化,新生儿出生体重按分娩孕周标准化,孕妇孕早期FT3水平与新生儿出生体重呈正相关(r=0.049,P=0.040),孕早期FT4水平与新生儿出生体重呈负相关(r=-0.069,P=0.004);将孕早期孕妇按BMI分层,BMI为18.5~<23.0 kg/m^2组FT3水平与新生儿出生体重呈正相关(r=0.063,P=0.038),BMI≥23.0 kg/m^2组FT4水平与新生儿体重呈负相关(r=-0.113,P=0.044);混合线性效应回归模型分析结果显示,孕妇甲状腺激素水平与新生儿出生体重不存在相关关系。结论正常孕妇随孕周增加,TSH水平上升,FT3、FT4水平下降,其甲状腺激素水平与新生儿出生体重不存在相关关系。
