Interpregnancy Interval After Termination of Pregnancy and the Risks of Adverse Outcomes in Subsequent Birth

Abstract

Slightly but significantly increased estimated risk of preterm delivery in subsequent pregnancy was seen when the interpregnancy interval after termination of pregnancy was less than 6 months. These data emphasize the need for prompt initiation of effective contraception after termination and enable counseling the patient for optimal conception interval.

In vitro fertilization, interpregnancy interval, and risk of adverse perinatal outcomes

“…For both IVF and non-IVF deliveries following a non-live pregnancy outcome, short IPI was not associated with increased risk for adverse perinatal outcomes. These findings are consistent with some (4,8,9), but not all (10,11), studies. California birth certificate data showed slightly protective associations between short IPIs following a non-live pregnancy (4) outcome and PTB, similar to our findings for the non-IVF population.…”

“…California birth certificate data showed slightly protective associations between short IPIs following a non-live pregnancy (4) outcome and PTB, similar to our findings for the non-IVF population. In contrast, Finnish population-based data showed that PTB risk was higher with short IPI following pregnancy terminations (11). For those planning an IVF pregnancy after a pregnancy loss, the data from the current study did not suggest a significant increase in risk for the adverse outcomes when pregnancies are less than a year apart.…”

“…Adverse perinatal outcomes may be associated with short IPI due to insufficient maternal physiologic recovery from the previous pregnancy (5–7) and with long IPI due to comorbidities associated with increasing maternal age (1,3). Although fewer in number, most studies following non-live pregnancy outcomes suggest no increased risk for adverse perinatal outcomes after short IPIs (4,8–11). The most recent recommendation regarding pregnancy spacing is from 2005, when the World Health Organization (WHO) recommended IPIs >24 months following a live birth and >6 months following a spontaneous or induced abortion (12).…”

Hazards of Repeat Pregnancy during Adolescence: A Case-control Study

“…5 Some studies have shown obstetric outcomes as an independent determining factor in the incidence of adolescent repeated pregnancies, observing longer inter-pregnancy intervals among women who experienced prenatal and/ or childbirth complications. 7 However, it has been also observed the opposite, as many women with history of poor outcomes during their first pregnancy tend to have a rapid repeat pregnancy, with a less than 12 months between deliveries interval. 8 It appears that, to reduce adolescent pregnancy rates in developed and developing countries, actions should be focused on a multifaceted and interdisciplinary management that address not only the risk factors and risk-behavior, but also aims for social and cultural factors that influence young people's decision making.…”

Adverse Neonatal Outcomes and Its Associated Factors Among Mothers with Short and Recommended Interpregnancy Interval, in Awi Zone Public Hospitals, 2020.

“…Studies from developed countries showed that the risk of developing adverse neonatal outcomes to be higher in pregnancies with short IPI (10)(11)(12). Other reports from developed countries showed an increased risk of developing preterm birth and LBW eventhough they show insigni cant association for other adverse neonatal outcomes (13). Similarly the effect of short IPI on adverse neonatal outcomes among developing countries was also supported by many literatures (14,15).…”
