Summary Background. Adherence to asthma medications is a significant problem among pregnant women. Objective. To evaluate asthma medication adherence in pregnant women and to determine the factors that may predict non-adherence in a real-life setting. Methods. A cross-sectional study was performed with pregnant women with asthma followed in a specialized asthma consultation at the Pulmonology Department, between 2014 and 2019. Sociodemographic and clinical variables were collected. Structured telephone interviews were conducted to determine regular medication use during pregnancy. Multiple logistic regression was used to identify predictive factors of asthma medication non-adherence (cessation or dose reduction). Results. A total of 82 pregnant women were included: mean age of 31.3 ± 6.5 years, non-adherence was detected in 29% (n = 24). Multivariable logistic regression analysis revealed that mild asthma during pregnancy (OR, 4.8; 95% CI 1.4-17.1, p = 0.015) and single, separated or divorced mothers (OR, 4.0; 95% CI 1.3-11.8, p = 0.014) were independent predictors of poor adherence to asthma medications. Conclusions. Asthma severity and marital status can strongly predict the asthma medication non-adherence in pregnant females. These findings may help improve asthma education strategies to promote.
