ChiLDhooD obesity

The rise in childhood obesity is believed to be due to increases in poor nutrition  and inactivity. Television, computers, and other electronics are more popular with children today but generally offer no physi- cal exercise.
National guidelines recommend 150 minutes of physical activity per week for elementary school–age children and 225 minutes per week for older children and teens. In one survey completed by the Centers for Disease Control, 27.8 percent of high school girls and 43.8 percent of high school boys reported at least 60 minutes of exercise at least five times per week. High school boys are more likely than girls to be active because they are more likely to participate in sports. According to researchers at the University of South Carolina, one-third of teens are unfit, based on a study of more than 3,000 teens from 1999 to 2002. The definition of unfit was determined by a treadmill test where the teens heart rates were monitored. The researchers found that overweight teens are much more likely to fail the fitness test than normal-weight teens and that boys are slightly more likely to meet the fitness standard than girls. The findings were troubling to medical professionals because it is well accepted that unfit teens are much more likely to be unfit adults.
