Recently, an association was reported between prenatal and postnatal exposure to cell phones and neurobehavioral problems in children at the age of 7 years.
A birth cohort was established in Sabadell, Spain between 2004 and 2006. Mothers completed questions about cell phone use in week 32 of the pregnancy (n = 587). Neurodevelopment of their children was tested at age 14 months using the Bayley Scales of Infant Development (n = 530).
We observed only small differences in neurodevelopment scores between the offspring of cell phone users and nonusers. Those of users had higher mental development scores and lower psychomotor development scores, which may be due to unmeasured confounding. There was no trend with amount of cell phone use within users.
This study gives little evidence for an adverse effect of maternal cell phone use during pregnancy on the early neurodevelopment of offspring.
最近有研究报告称，儿童在 7 岁时存在产前和产后暴露于手机与神经行为问题之间的关联。
西班牙萨瓦德尔于 2004 年至 2006 年期间建立了一个出生队列。母亲在妊娠第 32 周时完成了有关手机使用的问题（n=587）。在 14 个月大时，使用贝利婴幼儿发展量表对其子女的神经发育进行了测试（n=530）。
我们仅观察到手机使用者和非使用者的子女的神经发育评分存在微小差异。使用者的心理发育评分较高，精神运动发育评分较低，这可能是由于未测量的混杂因素所致。在使用者中，手机使用量与结果之间没有趋势关系。
本研究几乎没有证据表明母亲在怀孕期间使用手机会对后代的早期神经发育产生不良影响。
