目標：手機使用已越趨頻繁，然而手機之電磁波對於孩童健康發展之不良影響仍有爭議。本研究之目的為，描述從妊娠期到產後一年之母親手機使用情形，並進一步探討其手機使用量和孩童神經認知行為發展之影響。方法：自2004年至2005年間，收集來自大台北地區不同醫療院所的產婦及其新生兒為研究對象，最終納入133對產婦及其新生兒進行分析。我們使用「嬰幼兒綜合發展測驗」（Comprehensive Developmental Inventory for Infants and Toddlers,簡稱CDIIT）以及「魏氏兒童智力量表第四版」（Wechsler Intelligence Scale for Children-Fourth edition,簡稱WISC-IV）評估孩童之神經認知行為發展。另外，我們也使用「瑞文氏圖形推理測驗」（Standard Progressive Matrices, 簡稱SPM+）評估母親智力。藉由自填式問卷評估母親的手機使用量，再使用迴歸模式進行統計分析。結果：從妊娠期至產後一年，多數的母親每天手機的接聽通數皆少於3通，且每通電話之通話時間皆少於3分鐘。研究結果並未發現手機暴露對於孩童的神經行為發展有不良之影響。結論：目前仍未有明確的證據足以證明手機之暴露會造成孩童神經行為之不良影響，未來仍需要更多的研究針對此議題進行探討。

Objectives: Today, mobile phone use is common and has increased rapidly in many countries. The health effects of exposure to mobile phone use on children are controversial. We described maternal mobile phone use from pregnancy until the 12 months post-birth and examined the association between exposure to mobile phone use and the children's neurocognitive development in the general population in Taipei, Taiwan. Methods: The study was a part of the Taiwan Birth Panel Study. A total of 133 pairs of parents and their singleton child were recruited into this study. We used the Comprehensive Developmental Inventory for Infants and Toddlers (CDIIT) and Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) to assess child neurocognitive development. We also assessed the intelligence of the mothers using the Standard Progressive Matrices Plus (SPM+). Mothers completed questionnaires to report their mobile phone use. Regression modeling was used to estimate the association between mobile phone exposure and children's neurocognitive development. Results: Most of the mothers answered less than 3 phone calls per day, and the call duration was less than 3 minutes for each phone call from pregnancy until 12 months post-birth. We found no significant association between maternal mobile phone use and neurocognitive development in young children. Conclusions: There is no convincing evidence that maternal mobile phone use has an adverse effect on the neurocognitive development of young children. Prospective research using a personal exposure assessment is needed to elucidate a causal relationship.
