TRENTON, N.J. – Use of cholesterol and blood pressure medicines by young adults appears to be rising rapidly – at a faster pace than among senior citizens, according to an industry report being released Tuesday.

Experts point to higher rates of obesity, high blood pressure and high cholesterol problems among young people. Also, doctors are getting more aggressive with preventive treatments.

“This is good news, that more people in this age range are taking these medicines,” said Dr. Daniel W. Jones, president of the American Heart Association.

Still, he said many more people should be on the drugs that lower cholesterol or blood pressure and which have been shown to reduce risks for heart attack and stroke.

The new data, from prescription benefit manager Medco Health Solutions Inc., indicate use of cholesterol-lowering drugs among people aged 20 to 44, while still low, jumped 68 percent over a six-year period.

The rate rose from 2.5 percent in 2001 to just over 4 percent in 2006 among Medco customers.

That means roughly 4.2 million Americans in that age group are now taking cholesterol medicines.

Meanwhile, use of blood pressure medicines increased 21 percent, from about 7 percent of 20- to 44-year-olds in 2001 to over 8 percent in 2006. That translates into about 8.5 million Americans in that age group taking drugs to lower their blood pressure.

“It was a surprise to us,” said Dr. Robert Epstein, chief medical officer at Franklin Lakes, N.J.-based Medco. “Maybe the fact that we’re seeing more young people with high cholesterol and blood pressure is indicative of the epidemic of obesity and overweight that we’re seeing in this country.”
