Lazy teens in line for metabolic risk

Watching several television shows a day at 16 years of age resulted in a twofold increased risk of metabolic syndrome at age 43 compared with those who watched one show a week.

Teens who exercised several times a month were more than twice as likely to develop metabolic syndrome compared with those exercising daily, the study showed.

TV viewing in the mid-teens was associated with central obesity, low HDL cholesterol and hypertension in middle age.
