Abstract：【Objective】 To explore the effect of different gestational interval on the pregnancy outcome of elderly singleton pregnancy.【Methods】 the clinical data of 880 cases of elderly singleton pregnancy in our hospital from January 2013 to December 2018 were retrospectively analyzed. According to the different delivery interval, they were divided into group A (1-4 years), group B(5-9 years) and group C (≥10 years). The incidence of maternal complications, labor process time and neonatal birth of the three groups were compared. 【Results】 The total incidence of maternal complications in group C was 21.25%(34/160), which was significantly higher than that in group A (14.04%,48/342) and group B (11.11%,42/378), and the difference was statistically significant (P<0.05). But there was no significant difference in the total incidence of maternal complications between group A and group B (P>0.05); the time of the first stage of labor in group A, group B and group C increased in turn, and the difference was statistically significant (P<0.05); The proportion of neonatal asphyxia and transfer to ICU in group C was significantly higher than that in group A and group B (P>0.05), but there was no significant difference between group A and group B (P>0.05). Among 880 cases of single pregnancy, 140 cases had adverse pregnancy outcomes, and the incidence rate was 15.91%. Univariate analysis showed that maternal age, delivery interval, abortion history, adverse pregnancy habits, pregnancy complications and pregnancy complications were related to adverse pregnancy outcome (P<0.05); multivariate logistic regression analysis showed that age ≥ 42 years old, delivery interval ≥ 10 years, abortion history, adverse pregnancy habits, pregnancy complications and pregnancy complications were independent risk factors for adverse pregnancy outcomes in elderly pregnant women (P<0.05). 【Conclusion】 The incidence of complications, the time of the first stage of labor, neonatal asphyxia and the probability of transferring to ICU increases with the extension of gestational interval.
