A recent study found improvements in lung function and body mass index among children and young adults with cystic fibrosis both in the United States and Canada from 1990 to 2013, though the American patients improved faster than those in Canada.
The study, “Comparison of Nutrition and Lung Function Outcomes in Patients with Cystic Fibrosis Living in Canada and the United States,” appeared in the American Journal of Respiratory and Critical Care Medicine.
The analysis — which included data from 5,149 patients in the Canadian Cystic Fibrosis Registry and 37,772 patients in the U.S. Cystic Fibrosis Foundation Registry — compared changes in lung function and BMI among CF patients in both countries from 1990 to 2013.
It found that, while lung function improved in both countries, Americans with CF born after 1990 are nutritionally healthier than those north of the border, and that certain age groups showed faster improvement in the United States.
