PURPOSE: The prevalence of short interpregnancy intervals (IPI) and associated rates of preterm birth has been understudied in Asian and Pacific Islander populations. We sought to estimate rates of short IPI among Asian subgroups and Pacific Islanders and associated risk of preterm birth. MATERIALS AND METHODS: For this retrospective cohort study, we linked records of women in California with a first birth in 1999-2000 and a second birth before 2005 with hospital discharge data...

INTRODUCTION: Reduced chorionic villous vascularization is associated with first trimester miscarriage and second trimester fetal loss. Differences in villous vascularization have been observed in combination with complications in the third trimester of pregnancy. The aim of this study was to investigate whether abnormal morphology and reduced chorionic villous vascularization in first trimester miscarriages are associated with an increased risk on adverse outcome and/or pregnancy complications in subsequent pregnancy...

BACKGROUND: Short interpregnancy interval (SIPI), defined as 18 months or fewer between delivery and subsequent conception, has become an independent marker of maternal and child health. METHODS: We performed a secondary analysis of 18 months of data from The First Baby Study, a prospective cohort of women followed from pregnancy through 3 years after their first birth. Women with SIPIs by 6, 6 to 12, and 12 to 18 months were compared with those without conceptions at those times...

OBJECTIVE: To examine the association between the interpregnancy interval (IPI) and preterm birth, low birth weight, and SGA birth in a developed country with universal health coverage. METHODS: We conducted a secondary analysis of data housed at the Manitoba Centre for Health Policy. All live births in Manitoba hospitals over a 29-year period were identified and consecutive births to the same mother were grouped into sibling pairs to calculate the IPI for the younger siblings...

Objective Our objective was to determine if the relationship between interpregnancy interval (IPI) and preterm delivery was related to cervical shortening. Methods This is a secondary analysis of a prospective cohort study designed to assess the relationship between cervical length (CL) and preterm delivery. Multiparous patients, who had transvaginal CLs obtained at 22 to 24 weeks and complete pregnancy outcome data available were included. The women were divided into two groups: Group 1 with an IPI of ≤ 1 year and Group 2 with an IPI of > 1 year...

BACKGROUND: Considerable racial and ethnic disparities have been identified in maternal and infant health in the United States, and access to postpartum care likely contributes to these disparities. Contraception is an important component of postpartum care that helps women and their families achieve optimal interpregnancy intervals and avoid rapid repeat pregnancies and preterm births. National quality measurements to assess postpartum contraception are being developed and piloted. OBJECTIVE: To assess racial/ethnic variation in receipt of postpartum care and contraception among low-income women in California...

BACKGROUND: Repeat pregnancies after a short interpregnancy interval are common and are associated with negative maternal and infant health outcomes. Few studies have examined the relative effectiveness of postpartum contraceptive choices. OBJECTIVE: We aimed to determine the initiation trends and relative effectiveness of postpartum contraceptive methods, with typical use, on prevention of short delivery intervals (≤27 months) among women with access to universal healthcare, including coverage that entails no co-payments and allows unlimited contraceptive method switching...

OBJECTIVE: To examine the association between interpregnancy interval and maternal-neonate health when matching women to their successive pregnancies to control for differences in maternal risk factors and compare these results with traditional unmatched designs. METHODS: We conducted a retrospective cohort study of 38,178 women with three or more deliveries (two or greater interpregnancy intervals) between 2000 and 2015 in British Columbia, Canada. We examined interpregnancy interval (0-5, 6-11, 12-17, 18-23 [reference], 24-59, and 60 months or greater) in relation to neonatal outcomes (preterm birth [less than 37 weeks of gestation], small-for-gestational-age birth [less than the 10th centile], use of neonatal intensive care, low birth weight [less than 2,500 g]) and maternal outcomes (gestational diabetes, beginning the subsequent pregnancy obese [body mass index 30 or greater], and preeclampsia-eclampsia)...

OBJECTIVE: To assess whether the length of the interpregnancy interval after termination of pregnancy influences the risk of preterm birth, low birth weight, and small-for-gestational-age neonates in a subsequent pregnancy. METHODS: In this register-based study, we included all women (N=19,894) who underwent termination of pregnancy between 2000 and 2009 and whose subsequent pregnancy ended in live singleton delivery. The women were divided into five groups depending on the interpregnancy interval between termination of pregnancy and subsequent conception: interpregnancy interval less than 6 months (n=2,956), 6 to less than 12 months (n=3,203), 12 to less than 18 months (n=2,623), 18 to less than 24 months (n=2,076), and 24 months or greater (n=9,036)...

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with lifelong impacts. Genetic and environmental factors contribute to ASD etiology, which remains incompletely understood. Research on ASD epidemiology has made significant advances in the past decade. Current prevalence is estimated to be at least 1.5% in developed countries, with recent increases primarily among those without comorbid intellectual disability. Genetic studies have identified a number of rare de novo mutations and gained footing in the areas of polygenic risk, epigenetics, and gene-by-environment interaction...

BACKGROUND: In Ohio, the infant mortality rate is above the national average and the black infant mortality rate is more than twice the white infant mortality rate. Having a short interpregnancy interval has been shown to correlate with preterm birth and low birthweight, but the effect of short interpregnancy interval on infant mortality is less well established. OBJECTIVE: We sought to quantify the population impact of interpregnancy interval on the risk of infant mortality...

AIM: Several population-based studies have been conducted to determine whether maternal exposures are involved in the pathophysiology of autism spectrum disorder (ASD). We review these studies and describe the factors not associated with increased risk for ASD development. METHODS: We identified studies describing associations between maternal exposures and ASD development. These studies include the Childhood Autism Risks from Genetics and the Environment, Nurses' Health Study II, and the Swedish population registry...

OBJECTIVE: Short interpregnancy interval (IPI), <18 months between pregnancies, is a potential cause of adverse delivery and birth outcomes, and may be a particular issue among those with other risks. Our goal was to examine IPI and delivery/infant complications in Tennessee. METHODS: Birth certificate/vital records data included 101,912 women with a previous delivery. IPI groups (<6, 6-12, 12-18, 18-60 months) were compared on outcomes. RESULTS: Thirty-nine percent of the deliveries had IPI <18 months, 9% were <6 months, rates 11% and 27% higher than nationally...

BACKGROUND: A short interpregnancy interval (IPI) following a delivery is believed to be associated with adverse outcomes in the next pregnancy. The optimum IPI following miscarriage is controversial. Based on a single large-scale study in Latin and South America, the World Health Organization recommends delaying pregnancy for 6 months after a miscarriage to achieve optimal outcomes in the next pregnancy. OBJECTIVE AND RATIONALE: Our aim was to determine if a short IPI (<6 months) following miscarriage is associated with adverse outcomes in the next pregnancy...

BACKGROUND: To date, several studies concerning the effects of induced abortion (IA) on women's later psychosocial well-being and future delivery complications have been published. However, the lack of reports on woman's physical well-being during their first full-term pregnancy occurring after IA is what inspired the current study. Here, we evaluate the physical well-being and use of maternity services of first-time mothers with a history of IA. METHODS: Finnish National Birth Registry data from 2008 to 2010 were linked with the Induced Abortion Registry data from 1983 to 2007...

BACKGROUND: Results from uterine artery Doppler investigations suggest that the aetiology of late preeclampsia with fetal growth restriction may be more similar to the aetiology of early preeclampsia than with late preeclampsia without fetal growth restriction. We hypothesised that a small-for-gestational-age (SGA) birth in a late preeclamptic pregnancy may be associated with increased subsequent risk of early preeclampsia. We also studied effects of maternal factors on risks of preeclampsia recurrence...

STUDY QUESTION: After an initial midtrimester loss, is the interval to the next conception associated with the risk of a recurrent loss? SUMMARY ANSWER: Among women who had a pregnancy loss at 14-19 weeks gestation, conception at least 3 months after this initial loss was associated with a reduced risk of a recurrent loss. WHAT IS KNOWN ALREADY: A short interpregnancy interval (IPI) has been thought to increase risk but recent studies of pregnancy after a loss have found no effect; however, these studies have been based almost entirely on an initial first trimester (<14 weeks) loss...

Objectives The goals of interconception care are to optimize women's health and encourage adequate spacing between pregnancies. Our study calculated trends in interpregnancy interval (IPI) patterns and measured the association of differing intervals with birth outcomes in California. Methods Women with "non-first birth" deliveries in California hospitals from 2007 to 2009 were identified in a linked birth certificate and patient discharge dataset and divided into three IPI birth categories: <6, 6-17, and 18-50 months...
