TUESDAY, Dec. 10, 2024 (HealthDay News) — For adults with asthma, the prevalence of cost-related medication nonadherence (CRN) decreased from 2011 to 2022, according to a study published online Dec. 9 in Thorax.
Chun-Tse Hung, Pharm.D., from Taipei Medical University in Taiwan, and colleagues used data from the 2011 to 2022 National Health Interview Survey to examine trends, prevalence, and determinants of CRN and its impact on asthma control among U.S. adults with asthma. Data were included for 30,793 adults with asthma, representing 8.1 percent of the U.S. population.
The researchers observed a declining trend in the prevalence of CRN among U.S. adults with asthma from 2011 to 2022. Due to cost, about one in six adults with asthma were nonadherent to medications. Factors that were associated with CRN included demographics and comorbidities. The risk for experiencing asthma attacks and emergency department visits for asthma was increased among adults with asthma who had CRN (adjusted odds ratios, 1.95 and 1.63, respectively).
“Since asthma is one of the leading chronic diseases, the burden in cost-related nonadherence to medications highlights the need for appropriate policies and social support to address such problems,” the authors write.
