我只问大家一个问题 若你们将来生出一个 在一岁内头围增长缓慢的儿女 你们该怎办? 我对研究本身的评论是 凭空制造社会恐慌的研究人员 何不去死算了 就算他的研究结果都是对的又如何? 能治疗吗? 能弃养吗? 除非有一天 能在一岁内发现并能治疗 否则这种研究计划早该被否定 ※ 引述《[email protected] ( )》之铭言： : 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. Gale, PhDa, Finbar J. O'Callaghan, PhDb, Maria Bredow, MBChBc, : Christopher N. Martyn, DPhila and the Avon Longitudinal Study of Parents and : Children Study Team : a Medical Research Council Epidemiology Resource Centre, University of : Southampton, Southampton General Hospital, Southampton, United Kingdom : b Departments of Paediatric Neurology : c Community Child Health, Bristol Royal Hospital for Children, Bristol, : United Kingdom : OBJECTIVE. 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. --
