HEALTH MANAGEMENT. Study casts a wider net for risky blood pressure in children

NEW YORK (Reuters Health) - could more children than previously assumed his risk of dangerously high blood pressure, with more than a quarter with blood vessels, which look like the much older, according to a new study.
Since there is a theoretical possibility that some of these children, a stroke or a heart attack, which might suffer down road, say the researchers, that the results mean that all children should their blood pressure measured.
"I believe it is important that everyone for high blood pressure, is shown," said Dr. Karen Redwine Arkansas Childrens Hospital in little rock, which the results in the journal of Pediatrics are displayed.
"The overall rate for the development of high blood pressure, if you are a teenager is still very low," added to them, in an interview with Reuters Health. "But it is a subset of people, the development of high blood pressure somewhere between two and five times, that is, and many of those are children, now normally would apply."
These children have slightly increased blood pressure and diagnosed with so-called "Prehypertension." The label is disputed, however, because no disease to describe it - it is a risk factor for the development of later high blood pressure, which itself is a risk factor for heart disease.
An expert, who said not part of the new study he worried it could be used, to push drugs without evidence, that they do something good children.
"What me a little worried is that they are talking about the pharmacologic therapy,", said Dr. Curt D. Furberg, expert on heart disease prevention and drug safety at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina.
"If I me the author list, it is one of the Bristol-Myers Squibb," he added. "Pharmaceutical companies want to increase their market." "In this area sense not taking into account the healthy young children for pharmacological therapy."
The national heart, lung and Blood Institute in 2004 defined Prehypertension in children as a top blood pressure number between 120 and 139 or a lower number between 80 and 89. high blood pressure starts at 140 over 90.
If changes of lifestyle such as cutting down on salt and exercise sufficient to control high blood pressure in children, NHLBI advises drugs to try.
In adults the ups hypertension of the risk of stroke and heart attack a few percent. However, for children, the NHLBI recognizes that the long-term effects unknown are with high blood pressure for children, as are the side effects of drug treatment.
"In my mind, there are many more pressing issues in medicine as a screening for hypertension among young people, where we don't even know if treatment is useful," Furberg, Professor of public health, told Reuters Health.
The new study is an attempt, estimate how often children with Prehypertension further to develop full-blown high blood pressure or hypertension.
Development of data from a large test study - sponsored by pharmaceutical companies-at Texas schools, found Redwine and colleagues, that 11 of 1,006 students developed high blood pressure during the study.
This corresponds to a rate of 1 in 200 young people each year. Although the rate for children with Prehypertension appeared similar, a broader definition tripled created by Redwine and her colleagues nearly the rate.
After only a blood pressure higher than normal group a child in the "at risk" would set the new definition.
Until now, Redwine, explains to doctors think that a high blood pressure measurement only a Zufall--could be because the child nervously or somewhat ill was used.
Now, said she, "when it is raised only once, then you must observe and monitor it."
Currently, not the NHLBI recommend drug therapy for children with Prehypertension. But the new report suggests the investigating of the use of drugs in the "endangered."
According to the Texas screening study could that be, more than 26 percent of U.S. teenagers with the new definition-including healthy children who are not overweight.
Furberg and other critics is Prehypertension--not to mention the extended definition in the new students-a concept that comes with over slide diagnosis, over treatment and wasteful expenditure.
He said "That's what the industry is trying to do, to get people to drugs,". "they insist that for adults, and now they seem to children, which is tedious."
Redwine neutralized, although their co-authors at Bristol-Myers Squibb is busy, not drug use in children with Prehypertension are in favour of her report.
"It is not the point to say that they have to be," said Reuters Health.
The US preventive services task force, a State-sponsored group of Experts recommends screening adults for high blood pressure. It is currently the guidelines 2003 updated for children and young people, who pointed out that the evidence is not sufficient to weigh the harm and the benefits of screening children.
