Abstract

Background: Randomized trials of antenatal steroid administration (ANS) for extreme or moderate preterm pregnancies excluded women with diabetes mellitus (DM) and included few with preeclampsia. Methods: Cohort study (n = 1,813) including moderate preterm births [290/7–336/7wks’ gestational age GA)] before (Epoch-1) and after (Epoch-2) expansion of ANS administration to women with hypertensive disorders (HTN) and/or DM. We compared surfactant administration in Group-1 (neither HTN nor DM), Group-2a (HTN not DM), Group-2b (DM not HTN) and Group-2c (DM and HTN). Results: Surfactant administration was less frequent after ANS in Group-1 [adjusted odds ratio (aOR) 0.54, 95% confidence interval (CI) 0.31, 0.93, P = 0.03], Group-2a (aOR 0.36, CI 0.22, 0.58, P < 0.001) and Group-2c (aOR 0.29, CI 0.12, 0.71, P = 0.007) but not Group-2b (P = 0.64). Conclusions: ANS administration was independently associated with less surfactant administration in moderately preterm neonates whose mothers had neither HTN nor DM, and those with HTN, but not those with DM without HTN.
