新闻从业人士者写的跟研究人员写的, 可能带给读者的感受会有相当大的不同, 比方研究报告就不会用"胎儿头大=智力较高"这种标题杀人式的写法 建议大家看完这篇文章以後, 再来对新闻稿件或研究本身分开评论. 以下附上摘要. http://pediatrics.aappublications.org/cgi/content/abstract/118/4/1486 The Influence of Head Growth in Fetal Life, Infancy, and Childhood on Intelligence at the Ages of 4 and 8 Years Catharine R.

We investigated the effects of head growth prenatally, during infancy, and during later periods of development on cognitive function at the ages of 4 and 8 years. METHODS. We studied 633 term-born children from the Avon Longitudinal Study of Parents and Children cohort whose head circumference was measured at birth and at regular intervals thereafter. Their cognitive function was assessed with the Wechsler Preschool and Primary Scale of Intelligence at the age of 4 years and with the Wechsler Intelligence Scale for Children at the age of 8 years. Linear regression analysis was used to calculate postnatal head growth between successive time points, conditional on previous size, and to examine the relationship between head growth during different periods of development and later IQ. RESULTS. When the influence of head growth was distinguished for different periods, only prenatal growth and growth during infancy were associated with subsequent IQ. At 4 years, after adjustment for parental characteristics, full-scale IQ increased an average of 2.41 points for each 1-SD increase in head circumference at birth and 1.97 points for each 1-SD increase in head growth during infancy, conditional on head size at birth. At 8 years, head circumference at birth was no longer associated with IQ, but head growth during infancy remained a significant predictor, with full-scale IQ increasing an average of 1.56 points for each 1-SD increase in growth. CONCLUSION. The brain volume a child achieves by the age of 1 year helps determine later intelligence. Growth in brain volume after infancy may not compensate for poorer earlier growth. -- ┌─────◆ＫＫＣＩＴＹ◆─────┐KKMAN团队 全新力作 ◎◎KKBOX◎◎ │ bbs.kkcity.com.tw │知名歌手通通都有 所有新歌想听就听 └──《From:143.48.8.154 》──┘※※ 内容丰富多元的线上音乐台 ※※ --
