Spirometry is related to perinatal outcomes in pregnant women with asthma

A study is carried out to test the hypothesis that maternal asthma symptoms and pulmonary function are related to adverse perinatal outcomes. It is found that lower pulmonary function during pregnancy is associated with increased gestational hypertension and prematurity in the pregnancies of women with asthma, which can be due to inadequate asthma control or factors that are associated with increased asthma severity.
