PO-0640 Clinical Impact Of Maternal Characteristics In Preterm Infants With Low Birth Weight

Abstract

Maternal risk factors can cause prematurity. The aim of our study was to analyse the impact of maternal characteristics in preterm low birth weight. Methods A retrospective cohort study of a total of 81 preterm infants at our centre with low birth weight and ≤32 weeks of gestation was performed. We analysed perinatal risk factors. Data are expressed as a function of gestational age (GA) Results The mean maternal age was 30.3 ± 5.8 years. There were no statistically significant differences when comparing maternal age in according to birth weight (29.2 ± 5.7 vs. 31.5 ± 6.6 vs. 30.2 ± 4.6, p = 0.460 respectively) or gestational age (30.4 ± 5 vs. 30.3 ± 6, p = 0.964). The presence of maternal risk factors was very low: 3.7% were smokers, 2.5% had obesity. There were preeclampsia and diabetes gestational in 5 and 3 cases, respectively. Chorioamnionitis was diagnosed in 13.6% of pregnancies and 71.3% received antenatal steroids. The pregnancy was twins in 29.6% of cases. No significant differences were found when perinatal characteristics were examined in terms of birth weight, except for gestational diabetes (0% vs. 0% vs. 13.6% in low birth, p = 0,016). Maternal age did not influence in neonatal mortality (30.2 ± 5 years in preterm infants living vs. 30.7 ± 6 years in those died, p = 0.784. Conclusions In our series, the presence of maternal risk factors was very low. We were not found significant differences in according to birth weight or impact on neonatal mortality.
