Short-term clinical outcomes of neonates of secundiparous mothers: a single-center cohort study / 中国当代儿科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the short-term clinical outcomes of neonates of secundiparous mothers, and to provide a reference for the clinical practice after the change in birth policy.</p><p><b>METHODS</b>A cohort study was performed for the parturients and their neonates born in Yongkang Maternal and Child Health Care Hospital in Zhejiang, China between June 2015 and April 2016. According to the parity of the mother, the neonates were divided into primiparous group and secundiparous group. The short-term clinical outcomes of neonates were compared between the two groups.</p><p><b>RESULTS</b>A total of 4 091 neonates who met the inclusion criteria were enrolled, and there were 2 023 neonates in the primiparous group and 2 068 in the secundiparous group. In the secundiparous group, most mothers (57.16%) were aged 26-34 years, and 16.49% were aged above 35 years. Compared with the primiparous group, the secundiparous group had a significantly higher rate of births by cesarean section (42.55% vs 25.06%; P<0.05). The percentages of neonatal respiratory distress syndrome (NRDS; 8.6% vs 3.4%) and transient tachypnea of the newborn (TTN; 7.2% vs 2.6%; P<0.05) in hospitalized neonates from the secundiparous group were significantly higher than in those from the primiparous group.</p><p><b>CONCLUSIONS</b>Elderly parturient women are not the major population of secundiparous parturients. The neonates of secundiparous mothers have a higher rate of births by cesarean section, which might be associated with increased percentages of NRDS and TTN in hospitalized neonates from the secundiparous mothers.</p>
