NEW YORK (Reuters) - With the hot summer months arriving, a new study warns that caregivers need to be thinking about the drowning hazards posed by portable pools, including inflatable and wading pools. Parents need to be aware that these pools can present the same risks for drowning, especially for young children, as in-ground pools which are typically thought of as a greater safety hazard, said study author Dr. Gary Smith. He and his colleagues found 209 recorded cases of kids drowning in these pools between 2001 and 2009, most of them occurring in summer. Thats a child every five days that is drowning in a backyard portable pool during the summer months, Smith, head of the Center for Injury Research and Policy at Nationwide Childrens Hospital in Columbus, Ohio, told Reuters Health. While this doesnt suggest that families shouldnt use inflatable pools or wading pools, parents, he said, need to put some thought into the safety issues when they go to the store, pick one of these up, and put them up in their backyard.
