Cell phone use during pregnancy is a public health concern. We investigated the association between maternal cell phone use in pregnancy and child's language, communication and motor skills at 3 and 5 years.
This prospective study includes 45,389 mother-child pairs, participants of the MoBa, recruited at mid-pregnancy from 1999 to 2008. Maternal frequency of cell phone use in early pregnancy and child language, communication and motor skills at 3 and 5 years, were assessed by questionnaires. Logistic regression was used to estimate the associations.
No cell phone use in early pregnancy was reported by 9.8% of women, while 39%, 46.9% and 4.3% of the women were categorized as low, medium and high cell phone users. Children of cell phone user mothers had 17% (OR = 0.83, 95% CI: 0.77, 0.89) lower adjusted risk of having low sentence complexity at 3 years, compared to children of non-users. The risk was 13%, 22% and 29% lower by low, medium and high maternal cell phone use. Additionally, children of cell phone users had lower risk of low motor skills score at 3 years, compared to children of non-users, but this association was not found at 5 years. We found no association between maternal cell phone use and low communication skills.
We reported a decreased risk of low language and motor skills at three years in relation to prenatal cell phone use, which might be explained by enhanced maternal-child interaction among cell phone users. No evidence of adverse neurodevelopmental effects of prenatal cell phone use was reported.
孕期使用手机是一个公共卫生问题。我们调查了孕期母亲使用手机与孩子3岁和5岁时的语言、沟通及运动技能之间的关联。
这项前瞻性研究纳入了45389对母婴，他们是挪威母亲与儿童队列研究（MoBa）的参与者，于1999年至2008年孕中期招募。通过问卷调查评估孕早期母亲使用手机的频率以及孩子3岁和5岁时的语言、沟通及运动技能。采用逻辑回归来估计关联。
9.8%的女性报告在孕早期未使用手机，而39%、46.9%和4.3%的女性被归类为低、中、高手机使用者。与未使用者的孩子相比，使用手机母亲的孩子在3岁时句子复杂度低的调整风险降低了17%（比值比[OR]=0.83，95%置信区间[CI]：0.77，0.89）。母亲低、中、高手机使用情况对应的风险分别降低了13%、22%和29%。此外，与未使用者的孩子相比，使用手机母亲的孩子在3岁时运动技能得分低的风险较低，但在5岁时未发现这种关联。我们未发现母亲使用手机与沟通技能低之间存在关联。
我们报告了产前使用手机与3岁时语言和运动技能低的风险降低有关，这可能是由于手机使用者中母婴互动增强所致。未报告产前使用手机对神经发育有不良影响的证据。
