Parents should be vigilant when their children are in and around water, including pools, ponds and bathtubs, Gaines said. Do not overlook the water.Many techniques used to deny access to swimming pools, such as fencing, are more expensive than the same cell pools, he said. We must find other strategies that are effective and convenient for portable pools.

For the study, Smith’s team used data from the U.S. Commission of 2001-2009 s for the safety of consumer products.

Because these pools are inexpensive and easy to assemble, many parents can not be considered high-risk pools, he said. The greatest risk for children under 5 years, researchers have found.

Experts said the study also raises concerns about the pool ladders. Most of the children in the pool using a scale that came with the pool, Smith said.

EST is the incidence of 2 to 3.5 per 10,000 live births, which affects more boys than girls . About 90 percent of cases occur during the first year of life, but can affect children up to 4 years. Although some cases have an unknown cause , many experts cite tuberous sclerosis and the lack of oxygen to the baby at birth as a common cause of symptoms

About every five days per child drowns in a pool laptop in the U.S., said lead researcher Dr. Gary A.

In a new study, researchers at Nationwide Children’s Hospital in Columbus, Ohio, the details of the drowning death of more than 200 children under 12 years due to a series of above ground swimming pools, some large and deep, other small and shallow.

WATCH: Parents and caregivers should monitor their children or near water at all times, and not to socialize, read or sleep.

About 40 % of drownings occurred in a swimming pool for children, Smith said.

They found that 94 % of children were under 5 and most were boys. In addition, about three-quarters of the deaths occurred in the courtyard of the child’s, usually during the summer.

More than 40 % of drownings occurred when the child was supervised, 39 % success without the supervision of adults and 18 % was attributed to a lack of supervision.

Although a number of security measures such as alarms and fences are available in-ground pools, Smith said, this is not the case for portable pools. The researchers call for the development of the industry fence alarm affordable and reliable and portable swimming pool covers.

Close supervision of children around water is very important, but monitoring is not just isn t enough, he said.

The report, published in the online edition of Pediatrics June 20, emphasizes the need for security measures around all swimming pools, safety advocates said.

That’s 18 inches or less water, Smith said. Children can drown in very small amounts of water. It takes only a few centimeters and a few minutes.

Children safe was worried about the increasing use of residential swimming pools that are too small for consumers to consider investing in fencing, but too large to make it easy to empty after use safe, secure, Meri-K Appy a president said Safe Children United States in a statement Friday. This important study confirms our hypothesis that the portable swimming courses all over America are at risk for children.

Dr. Barbara Gaines, director of the Trauma and Injury Prevention at Children’s Hospital of Pittsburgh, said it reminds us that if the water is very familiar, it’s also extremely dangerous.
