Flores KF, et al. - Using data from the enrollees in the National Health and Nutrition Examination Survey (2001–2016), researchers presented updated prevalence estimates of asthma and asthma medication use for women of childbearing age in the United States. They analyzed data from 11,383 women (aged 18–44 years), including 1,245 pregnant women. Having asthma was reported by 9.9% of women aged 18–44 years and 10.9% of pregnant women, following age-adjustment. In 2015–2016 and in 2003–2004, the highest and the lowest asthma prevalence rates were reported, respectively. The highest asthma prevalence rate was reported in women aged 18–44 years with Medicaid or State Children’s Health Insurance Program insurance coverage, obesity, diabetes, hypertension, and those who were current smokers. Use of asthma medications in the past 30 days was reported by 38.3% of asthmatic women. Overall, variations were observed in asthma burden across demographic and clinical features among women of childbearing ages.
