Even at the tender age of 10, nearly 32 percent of girls felt“too fat“and 31 pe
28、rcent said they were trying to diet.McVey, a researcher at the Hospital for Sick Children in Toronto, and her colleagues analyzed data collected in a number of surveys of southern Ontario school girls between 1993 and 2003, reporting their findings in Tuesdays issue of the Canadian Medical Associati
29、on Journal.Nearly 80 percent of the girls had a healthy body weight and only 7. 2 percent were considered overweight using standard weight-to-height ratios. Most researchers suggest the rate of overweight children in this country is several times higher than that figure.Nearly 30 percent of the girl
30、s reported they were currently trying to lose weight, though few admitted to dangerous behavior such as self-induced vomiting.Still, a test that measured attitudes towards eating showed 10. 5 percent of survey participants were already at risk of developing an eating disorder.“Were not talking about
31、 kids whove been prescribed a diet because theyre above average weight or overweight. Were talking about children who are within a healthy weight range. And they have taken it upon themselves to diet to lose weight, “ McVey said, acknowledging she found the rates disturbing. She said striking a bala

One study of Chicago neighborhoods showed that after-school programs resulted in less violence even in poor neighborhoods.After-school programs can
37、help to reduce crime and violence because they offer activities to children and youths during their out-of-school time.

Th

Programs may be too expensive, of poor quality, or hard to join.

48、n California. But researchers in Israel have found that caf-feinated coffee halves the bodys levels of this sleep hormone.Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six volunteers slept less well after a cup of caffeinated coffee than after drinking the same
49、 amount of decaf. On average, subjects slept 336 minutes per night after drinking caffeinated coffee, compared with 415 minutes after decaf. They also took half an hour to drop offtwice as long as usualand jigged around in bed twice as much.In the second phase of the experiment, the researchers woke the volunteers every three hours and asked them to give a urine sample. Shilo measured concentrations of a breakdown product of melatonin. The results suggest that melatonin
