- 试题详情及答案解析
- A new study has found evidence of aggressive(富于攻击性的)behaviors in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3, 000 5-year-olds.
Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. The women were also asked to complete a checklist of their children’s behaviors.
The researchers found that 43 percent of the boys and girls drank at least one daily serving of soda, 4 percent of the youngsters had four or more servings of soda to drink every day.
Shakira Suglia is with Columbia University’s Mailman School of Public Health in New York City. She worked on the study with researchers from the University of Vermont and Harvard University School of Public Health. She says they found that children who drank the most soda were more than two times as likely as those who drank no soda to show signs of aggression.
“For the children whoconsumedfour or more servings of soft drinks per day, we see an association between aggressive behaviors, attention problems and withdrawn behaviors. ”
The aggressive behaviors included destroying possessions belonging to others, taking part in fights and physically attacking people.
Doctor Suglia says it’s not clear why young children who drink a lot of soda have behavior problems.
“We can’t prove that this is a direct cause and effect relationship, having said that, there are a lot of ingredients in soda, a lot of ingredients that have not been examined in relation to behaviors. ”
Earlier studies of young adults have found the highest sugar levels in those who carry weapons and show signs of negative social behaviors.
