BackgroundAsthma is the most common potentially serious medical complication in pregnancy. The purpose of this study was to determine the association between maternal asthma and a spectrum of adverse neonatal and maternal outcomes.MethodsEvents during pregnancy and birth outcome were evaluated in 34 asthmatic as well as 1569 non-asthmatic pregnant women who were enrolled in a prospective cohort study undertaken at the antenatal clinics of Mobini Hospital in Iran. The women were interviewed and classified according to clinical severity and asthma control as per GINA guidelines. Information on asthma symptoms was collected by a questionnaire as well as by spirometry and physical examination. All subjects were followed until delivery, and postpartum charts were reviewed to assess neonatal and maternal outcomes. Eosinophil cells counts were obtained and total IgE was measured by ELISA. Results were assessed by multivariate logistic regression adjusting for maternal age and parity, and for birth outcomes, for gestational diabetes, and hypertension/pre-eclampsia.ResultsThe well-known relationship between family history of asthma and asthma in pregnancy was again supported (p < 0.001). Women with asthma had more bleeding events 3 weeks or more before delivery (OR 3.30, 95% CI 1.41–7.26), more often placenta problems (OR 6.86, 95% CI 1.42–33.02), and gestational diabetes mellitus (OR 3.82, 95% CI 1.06–13.75). No significant differences between asthmatic and non-asthmatic mothers regarding duration of gestation, birthweight, low Apgar scores, or neonatal respiratory difficulties were found. Total IgE antibody levels and eosinophil counts did not differ by asthma control and severity.ConclusionsAsthma in pregnancy poses some risk for pregnancy complications and adverse perinatal outcomes. Managing asthma effectively throughout pregnancy could benefit women and their babies and help to reduce the health burden associated with asthma during pregnancy.
Background
Asthma is the most commonly occurring respiratory illness during pregnancy. Associations with complications of pregnancy and adverse perinatal outcome have been established. However, little is known about quality of life (QoL) in pregnant women with asthma and how it relates to asthma control particularly for Iran.
Objective
To determine the relationship between asthma related QoL and asthma control and severity.
Methods
We conducted a prospective study in pregnant women with asthma. We used the Asthma Control Questionnaire and the Asthma Quality of Life Questionnaire (AQLQ) and the guidelines of the Global Initiative for Asthma for assessment of asthma severity.
Results
Among 1603 pregnant women, 34 were diagnosed with asthma. Of these 13 had intermittent, 10 mild, 8 moderate and 3 severe persistent asthma. There was a significant decrease of QoL with poorer asthma control (p = 0.014). This decline could be due to limitations of activity in those with poorer asthma control, which is underlined by the significant decline of QoL with increasing asthma severity (p = 0.024).
Conclusion
Although the majority of pregnant women with asthma had a favorable score in AQLQ, reduced QoL was related to increased asthma severity and poor asthma control. This underlines the importance of controlling asthma during pregnancy not only for the prevention of adverse pregnancy outcomes but also for the preservation of QoL.
