Asthma rates have indeed showed a steep decline albeit only for a handful of kids from affluent families whereas it continues to be on the rise for the poor children. According to the researchers, at the National Center for Health Statistics of the Centers for Disease Control and Prevention (CDC), asthma rates continued to rise for the poor kids in between 10 to 17 years of age living in the South of the US. The reports also showed adverse outcomes such as visits to emergency departments and hospitalizations.
However, the report published in the Pediatrics journal also says that the overall prevalence rate of asthma among kids of 18 years or less has declined from 9.3 % in 2012 to 8.3% in 2013. It is noteworthy though that the asthma prevalence continued to be the same among the Puerto Rican and white children in between 2011 and 2013. Dr. Lara Akinbami and her colleagues from CDC used multivariate adjusted models during the research. These researchers found that there was a linear increase in the asthma rates among poor children in between 10 to 17 years of age.
Disparities in Distribution of Asthma
Even after repeated measures to control the disease among children and to spread awareness to every stratum of the society, the socioeconomic and racial disparities continue to plague the childhood asthma distribution. Similar conclusions were made after analyzing the government questionnaire, National Health Interview Survey data that recorded the health problems of around 150,000 children. According to authors of the study, the analysis will require support from more data whether the asthma rates have indeed reversed or not.
A report published in the MedPage Today has authors offering several hypotheses reflecting upon recent improvement in the asthma rates. According to the report, several factors such as increased sensitization towards indoor allergens, hygiene allergens and improved identification of asthma are responsible for the decline. The authors wrote that no single explanation for changes in the asthma rates could be enough since it involves the interplay of complex factors.
