Good news for the United States: asthma rates among children have started falling. But, the childhood asthma rates for the poorest kids of the country are still a matter of concern, according to a government study.
Study researchers are trying to figure out sources behind the drop. The 13-year study suggests a plateau in obesity rates among US kids and the country’s declining air pollution could be the possible reason.
The study, which was conducted from 2001 to 2013, also showed slight increase in asthma rates among kids who are 17 or younger in the start. But it soon leveled off and then fell by the study’s end. Only 8.3% kids were with asthma, the study concluded at the end.
From 1980 to 1995, asthma rates in the US children doubled. The study noted slower increases after that. In 2010, childhood asthma rates were 9.3%. The study noticed downfall in the most recent years in children, younger than 5, and Mexican kids. “Rates plateaued among whites and those living in the Northeast and West, but increased in those ages 10 to 17, kids from poor families and those living in the South”, the study added.
During the study, the researchers noted increase among blacks, but at the end it plateaued. The study results are based on annual in-person government health surveys where over 150,000 kids’ parents were asked about their children’s asthma. The study didn’t include childhood asthma rates of 2014 which climbed slightly to 8.6%.
