The study found that children who gain more weight, and whose heads grow quickly during the first month of life, tend to have a higher IQ when they start school. Researchers at the University of Adelaide, in Australia studied 13,800 children who were born at fullterm. They found that those who put on 40% of their birth weight in the first four weeks had an IQ points higher than those who only put on 15% of their birth weight. Those who experienced the biggest growth in head circumference (頭圍 ) also had the highest IQs by the age of six. ―Head circumference is an indicator of brain volume, so a greater increase in head circumference in a newlyborn baby suggests more rapid brain growth,‖ says the led author of the study, Dr. Lisa Smithers. She added, ―Overall, newlyborn children who grew faster in the first four weeks had higher IQ scores later in life. Those children who gained the most weight scored especially high on verbal (言語 ) IQ at age 6. This may be because the neural (神經(jīng)的 ) structures for verbal IQ develop earlier in life, which means the rapid weight gain during the first month could be having a direct cognitive benefit for the children.‖ Previous studies have shown the association between early postnatal (產(chǎn)后的 ) diet and IQ, but this is the first study of its kind to focus on the IQ benefits of rapid weight gain in the first month of life. Dr. Smithers says the study further highlights the need for successful feeding of newlyborn babies. ―We know that many mothers have difficulty establishing breastfeeding in the first week of their babies’ life,‖ Dr. Smithers said. ―The findings of our study suggest that if babies are having feeding problems, there needs to be early intervention (干預(yù) ) in the management of that feeding.‖ 28. The study mainly shows that ________ A. head circumference is certainly connected to IQ. B. babies’ heads grow quickly during the first month. C. fullterm babies tend to be cleverer than premature babies.

There are ups and downs and unexpected turns. Abuse or neglect by adult can make the ride even rougher. But being bullied(欺凌 ) by another child can leave especially lasting scars. That39。s the finding of a new study. Bullied kids face a high risk of mental health problems as teens and as young adults. Indeed bullied kids might be worse off than those who had suffered physical abuse or neglect, the study found. Dieter Wolke works at the University of Warwick in England. Until recently, most studies of child victims focused not on bullying but on maltreatment, this psychologist says. Maltreatment includes physical or emotional abuse, neglect or other behaviors that can harm a child. Wolke39。s team wanted to better understand how bullying39。s longterm effects pare to those due to maltreatment. They focused on 4,026 children in the United Kingdom and 1,420 more in the United States. Information about bullying and maltreatment was collected for American children to age collected the same information for British youth up to age 16. The researchers also gathered data on eac
