{"id":"HHS-OASH-2026-0397-6354","number":"6354","name":"Alex Andreasen","organization":"","posted":"2026-10-28T04:00Z","received":"2026-10-21T04:00Z","body":"https://pmc.ncbi.nlm.nih.gov/articles/PMC5506372/pdf/nihms866566.pdf\n\n\"Methods—We used individual participant data from 83,884 mother-child pairs in the five cohorts\nfrom Denmark (1996–2002), Korea (2006–2011), the Netherlands (2003–2004), Norway (2004–\n2008), and Spain (2003–2008). We categorized cell phone use into none, low, medium, and high,\nbased on frequency of calls during pregnancy reported by the mothers. Child behavioral problems\n(reported by mothers using the Strengths and Difficulties Questionnaire or Child Behavior\nChecklist) were classified in the borderline/clinical and clinical ranges using validated cut-offs in\nchildren aged 5–7 years. Cohort specific risk estimates were meta-analyzed.\nResults—Overall, 38.8% of mothers, mostly from the Danish cohort, reported no cell phone use\nduring pregnancy and these mothers were less likely to have a child with overall behavioral,\nhyperactivity/inattention or emotional problems. Evidence for a trend of increasing risk of child\nbehavioral problems through the maternal cell phone use categories was observed for\nhyperactivity/inattention problems (OR for problems in the clinical range: 1.11, 95%CI 1.01, 1.22;\n1.28, 95%CI 1.12, 1.48, among children of medium and high users, respectively). This association\nwas fairly consistent across cohorts and between cohorts with retrospectively and prospectively\ncollected cell phone use data.\nConclusions—Maternal cell phone use during pregnancy may be associated with an increased\nrisk for behavioral problems, particularly hyperactivity/inattention problems, in the offspring. The\ninterpretation of these results is unclear as uncontrolled confounding may influence both maternal\ncell phone use and child behavioral problems.\"","attachments":[],"attachment_inventory":true,"withheld":false,"source":"https://www.regulations.gov/comment/HHS-OASH-2026-0397-6354","tags":["child-development","research-evidence"],"source_hash":"119ce27455d6d540b7748184012f59234cffe75a589bff2e483dfa2ca6343251","slug":"child-development-comment-6354","classification":{"id":"HHS-OASH-2026-0397-6354","body_sha256":"0cddb4fe7af53910ed62d8f75d19a56436d67ac1afb9e6c87a0c039a77e264f7","status":"ai_reviewed","primary_topic":"research","topics":[{"id":"research","evidence":"7 years.
