Kids’ cholestero­l levels down; fewer trans fats cited

- MIKE STOBBE

ATLANTA — Finally some good news about cholestero­l and kids: A big government study shows that in the past decade, the proportion of children who have high cholestero­l has fallen.

The results are surprising, given that the childhood obesity rate didn’t budge. How can that be? Some experts think that while most kids may not be eating less or exercising more, they may be getting fewer trans fats. That’s because the artery- clogging ingredient has been removed or reduced in many processed or fried foods such as doughnuts, cookies and french fries.

“That’s my leading theory,” said Dr. Sarah de Ferranti, director of preventive cardiology at Boston Children’s Hospital. She wrote an editorial that accompanie­s the study.

The study did not look at the reasons for the decline, but its lead author, Dr. Brian Kit of the Centers for Disease Control and Prevention, said the theory makes sense.

The research, released online Tuesday by the Journal of the American Medical Associatio­n, also showed that children’s average overall cholestero­l levels declined slightly.

Too much cholestero­l in the blood raises the risk of heart disease. It isn’t usually an immediate threat for most children, but those who have the problem often grow into adults with a high risk.

Kit and his colleagues drew data from an intensive national study that interviews people and does blood- cholestero­l tests. They focused on more than 16,000 children and adolescent­s over three periods — 1988- 94, 1999- 2002 and 2007- 10.

During the most recent period studied, 1 in 12 children ages 6 through 19 had high cholestero­l. That was down from 1 in 9 during each of the earlier periods — roughly a 28 percent decline.

The average overall cholestero­l level fell from 165 to 160. In children, 200 is con- sidered too high.

The study was the first in almost 20 years to show such a decline. Kids’ cholestero­l levels also fell between the 1960s and the early 1990s, probably because people were eating less fat.

The researcher­s in the latest study detected modest improvemen­ts in children’s levels of socalled good cholestero­l, which can protect the heart. That may be partly due to declines in teen smoking and childhood exposure to secondhand smoke over the last decade. Studies have found that chemicals in cigarette smoke can lower good cholestero­l.

The bigger news was what happened with bad cholestero­l and triglyceri­des. They went down by small but significan­t amounts.

Cholestero­l levels have been declining in adults, too. The incidence of high cholestero­l dropped about 27 percent in the last decade, from about 1 in 5 adults at the beginning of the period to 1 in 7 at the end.

But cholestero­l- lowering drugs known as statins were a big part of the reason for that decline — millions of adults take them. Children are rarely given statins.

Last year, a government- appointed panel urged widespread cholestero­l screening for children. It was controvers­ial because of concerns it would lead to more kids being given medicine. Experts say statins should be used in only the worst cases — less than 1 percent.

Artificial trans fats are known to decrease good cholestero­l and increase bad cholestero­l. In 2006, the federal government began requiring that packaged foods list the amount of trans fat per serving, a boon for careful shoppers.

Meanwhile, a push to take trans fats out of foods gained momentum. New York City banned artificial trans fats in restaurant food in 2008. California in 2010 became the first state to adopt such a ban. Even Crisco, the goopy shortening that was trans fat incarnate, was reformulat­ed to take it out.

“I love the idea that reduced use of hydrogenat­ed trans fats might be responsibl­e” for the new study’s results, Marion Nestle, a New York University professor of nutrition, food studies and public health, said in an email. “If so — and as usual it’s clear that more research is needed — it would mean that public health measures like the trans fat ban in New York City are actually doing enough good to be measurable.”

This is not the first study to suggest a payoff in trans fat policy efforts. The U. S. Department of Agricultur­e found that from 2005 to 2010, the average trans fat content in bakery items and other foods declined steeply. A small, preliminar­y CDC study published earlier this year found significan­t drops in trans fats in white adults between 2000 and 2009.

Despite the good news, experts remain worried.

Seventeen percent of U. S. children are obese, perhaps because they are still eating lots of carbohydra­tes and sugar. That, along with little exercise, can lead to diabetes and heart disease.

“We may have a small effect in the right direction from lower cholestero­l, but I’m worried it will be overwhelme­d by the earlier onset of obesity in younger and younger children,” de Ferranti said. “I’m still pretty worried about how many kids are going to wind up patients of adult cardiologi­sts.”
