妊娠期间暴露于中频电磁场（IF-EMF）对出生结局的影响尚不确定。我们使用日本产前队列研究的数据，调查了怀孕期间使用感应加热（IH）炊具（IF-EMF的主要来源）和早产（PTB）、低出生体重（LBW）、小于胎龄（SGA）与出生体重之间的关系。研究参与者是1,565名单胎妊娠的母亲和这些妊娠所生的婴儿。我们使用自填式问卷收集了此处提供的数据。对母亲年龄、居住地区、子女数量、家庭结构、母亲教育、母亲就业、母亲饮酒、怀孕期间吸烟、母亲体重指数、婴儿性别和出生时胎龄进行了调整。怀孕期间使用IH炊具与PTB风险降低独立相关：调整后的比值比为0.28（95%置信区间：0.07-0.78）。怀孕期间使用IH炊具与LBW，SGA或出生体重无关。这是第一项研究表明，怀孕期间使用IH炊具与PTB独立负相关。
The effects of exposure to intermediate‐frequency electromagnetic fields (IF‐EMFs) during pregnancy on birth outcomes are uncertain. We investigated the association between the use of induction heating (IH) cookers, which are major sources of IF‐EMFs, during pregnancy and preterm birth (PTB), low birth weight (LBW), small‐for‐gestational‐age (SGA), and birth weight, using data from a prebirth cohort study in Japan. Study participants were 1,565 mothers with singleton pregnancies and the babies born from these pregnancies. We collected the data presented here using self‐administered questionnaires. An adjustment was made for maternal age, region of residence, number of children, family structure, maternal education, maternal employment, maternal alcohol intake, smoking during pregnancy, maternal body mass index, baby's sex, and gestational age at birth. IH cooker use during pregnancy was independently associated with a reduced risk of PTB: the adjusted odds ratio was 0.28 (95% confidence interval: 0.07–0.78). IH cooker use during pregnancy was not associated with LBW, SGA, or birth weight. This is the first study to show that IH cooker use during pregnancy is independently inversely associated with PTB.
