Factors affecting asthma control in pregnant women with asthma.

<bold>Background:</bold> Asthma control in pregnant women is imperative as suboptimal control can have adverse repercussions on both fetal and naternal health. <bold>Objective:</bold> To identify factors that affect asthma control in pregnant women in local Pakistani population. <bold>Methods:</bold> Descriptive, cross-sectional study of 145 pregnant women with confirmed bronchial asthma. <bold>Results:</bold> Mean age was 30.39 ± 4.33 years with 65% being multiparous. 48% were non-compliant with treatment and less than 40% achieved asthma control. A chi-squared test applied showed that multiparity (p=0.003, treatment compliance (p<0.001), higher BMI (p<0.001), and proper inhaler technique (p<0.001) were statistically significant factors affecting affecting control in pregnant women while level of education and socioeconomic status did not exhibit any significant association. Multiple regression analysis qualified higher BMI, multiparity, treatment compliance, and inhaler technique as significant predictors of asthma control amongst pregnant women. <bold>Conclusion:</bold> Ensuring asthma control during pregnancy is important. High BMI, multiparity, correct inhaler technique and treatment compliance affect asthma control. Addressing these factors through regular ante-natal check-ups can significantly improve maternal and featal health.
