Interpregnancy interval

Sven Cnattingius, Anna-Karin Wikström, Olof Stephansson, Kari Johansson
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...

Objectives The purpose of this study is to evaluate the prevalence, impact, and interaction of short interpregnancy interval (IPI), pre-pregnancy body mass index (BMI) category, and pregnancy weight gain (PWG) on the rate of preterm birth. Methods This is a population-based retrospective cohort study using vital statistics birth records from 2006 to 2011 in OH, US, analyzing singleton live births to multiparous mothers with recorded IPI (n = 393,441). Preterm birth rate at <37 weeks gestational age was compared between the referent pregnancy (defined as normal pre-pregnancy maternal BMI, IPI of 12-24 months, and Institute of Medicine (IOM) recommended PWG) and those with short or long IPI, abnormal BMI (underweight, overweight, and obese), and high or low PWG (under or exceeding IOM recommendations)...

Objectives Assess the influence of maternal race on the association between interpregnancy interval (IPI) and risk of small for gestational age (SGA) and large for gestational age (LGA) births. Methods Statewide population-based cohort study of 380,520 singleton births. We calculated risk of SGA and LGA births following IPIs of 0 to <6, 6 to <12, 12 to <24 (referent), 24 to <60 months, and ≥60 months, by maternal race after adjustment for confounding influences. Results The highest risk for SGA among white women followed short IPI of 0 to <6 months [adjRR 1...

Objectives Pakistan is one of five nations contributing to half of the world's child mortality and holds under-five mortality rates which are nearly double global targets. Reasons for this shortfall include civil conflicts, political uncertainty, low education, poverty, rural-urban disparities, and limited health care access. The aim of this study was to explore associations between individual characteristics, community factors, and child mortality in Pakistan. Methods Data were derived from the 2012 to 2013 Pakistan Demographic and Health Survey, and included 7399 live births and 380 child deaths...

PURPOSE: The influence of the B-Lynch suture technique on subsequent fertility and pregnancy outcomes is not clear. In the present report, the authors describe the case of a very short interpregnancy interval following the successful placement of a B-lynch suture and discuss the associated problems. MATERIALS AND METHODS: A 33-year-old-woman underwent cesarean section after undergoing artificial induction of labor and subsequent atonic postpartum hemorrhage. Placement of a B-Lynch brace suture successfully stopped the bleeding and preserved the uterus...

OBJECTIVE: Elevated maternal psychosocial stress during pregnancy and accompanying changes in stress hormones may contribute to risk of adverse birth outcomes such as low birth weight and preterm birth. Relatedly, research on fetal programming demonstrates intriguing associations between maternal stress processes during pregnancy and outcomes in offspring that extend into adulthood. The purpose of this study was to test whether hypothalamic-pituitary-adrenal (HPA) patterns in mothers during the period between 2 pregnancies (i...
