Objectives To investigate the associations of interpregnancy interval (IPI) with miscarriage, stillbirth, preterm delivery and small for gestational age delivery. Methods The study population comprised all women who had a live birth and at least one subsequent pregnancy in Denmark during the period from 1994 to 2010 (N = 328,577). Linear regression was used to estimate risk differences for miscarriage, stillbirth, preterm delivery and small for gestational age delivery according to IPI. Results The results were heterogeneous: the risk of miscarriage increased monotonically with the length of the IPI...

OBJECTIVE: To evaluate pregnancy outcomes in patients with a history of wedge resection for interstitial ectopic pregnancy (WRIEP). METHODS: Retrospective cohort study of pregnancies with a history of WRIEP from 2000-2013 at two inner city hospitals in Detroit, MI. Pregnant matched controls (1:3) were selected and included patients with history of surgically treated tubal ectopic pregnancy and delivered patients without history of ectopic pregnancy. Pregnancy outcomes, including a composite, were compared among the groups...

We conducted this study to compare outcomes for pregnancies conceived ≤6 months after dilation and evacuation (D&E) with those conceived >6 months after D&E. This retrospective cohort study included women who underwent D&E (14-26 weeks) and were readmitted with a subsequent pregnancy. The primary outcome was the rate of preterm birth (<37 weeks). We identified 737 D&Es with 214 subsequent pregnancies. Outcomes were available for 85.5% of these pregnancies. Preterm birth <37 weeks occurred in 9...

BACKGROUND: The Solomon Islands is a Pacific nation with a maternal mortality of 114 per 100 000 births. Around 57% of pregnancies are unintended and only 15% of women attend their first antenatal visit in the first 12 weeks as recommended by the World Health Organization. AIMS: We sought to examine the socio-demographic predictors of unintended pregnancy and late antenatal booking (>18 weeks) among women attending antenatal care in Honiara. MATERIALS AND METHODS: From January 2014 to May 2015 we undertook a cross-sectional survey using a structured questionnaire on women presenting to the National Referral Hospital and community clinics in Honiara for antenatal care...

BACKGROUND: Closely spaced, unintended pregnancies are common among Medicaid beneficiaries and create avoidable risks for women and infants, including preterm birth. The Strong Start for Mothers and Newborns Initiative, a program of the Center for Medicare and Medicaid Innovation, intended to prevent preterm birth through psychosocially based enhanced prenatal care in maternity care homes, group prenatal care, and birth centers. Comprehensive care offers the opportunity for education and family planning to promote healthy pregnancy spacing...

BACKGROUND: Globally, prematurity is the leading cause of death in children under the age of 5. Many efforts have focused on clinical approaches to improve the survival of premature babies. There is a need, however, to explore psychosocial, sociocultural, economic, and other factors as potential mechanisms to reduce the burden of prematurity. Women's empowerment may be a catalyst for moving the needle in this direction. The goal of this paper is to examine links between women's empowerment and prematurity in developing settings...

OBJECTIVE: The objective of this study is to investigate the association between interpregnancy interval and success of vaginal birth after cesarean. STUDY DESIGN: Retrospective 10-year cohort study of pregnant women with one prior cesarean, who opted for trial of labor (n=36 653). Interpregnancy interval is the time between cesarean and next conception. Vaginal birth success rates were compared between six interval groups. Analysis was performed pooled as well as stratified for induction of labor...

OBJECTIVE: To assess whether interpregnancy interval length after a pregnancy loss is associated with risk of repeat miscarriage. METHODS: This analysis includes pregnant women participating in the Right From the Start (2000-2012) community-based prospective cohort study whose most recent pregnancy before enrollment ended in miscarriage. Interpregnancy interval was defined as the time between a prior miscarriage and the last menstrual period of the study pregnancy...

OBJECTIVE: To examine associations among interpregnancy interval, the duration from the preceding birth to the conception of the next-born index child, and adverse birth outcomes using designs that adjust for measured and unmeasured factors. METHODS: In this prospective cohort study, we used population-based Swedish registries from 1973 to 2009 to estimate the associations between interpregnancy interval (referent 18-23 months) and adverse birth outcomes (ie, preterm birth [less than 37 weeks of gestation], low birth weight [LBW; less than 2,500 g], small for gestational age [SGA; greater than 2 SDs below average weight for gestational age])...

PURPOSE: Examine associations between interpregnancy body mass index (BMI) change (difference in the pre-pregnancy BMIs of two consecutive pregnancies) and gestational diabetes mellitus (GDM), pre-eclampsia (PE), gestational hypertension (GHtn), primary cesarean delivery, and vaginal birth after cesarean delivery (VBAC). METHODS: Modified Poisson regression models estimated adjusted associations. RESULTS: Every 1-unit increase in interpregnancy BMI increased risks of GDM (relative risk [RR]: 1...

Intrauterine growth restriction was defined as occurring if birth weight of the newborn is below 10(th) percentile for gestational age. We investigated its maternal determinants in Riyadh, Saudi Arabia by comparing 76 cases to 76 controls to aid in early detection, diagnosis and proper prevention. A history of stillbirth, less than three years interpregnancy intervals, experiencing preeclampsia during pregnancy besides gaining less than nine kilograms during term pregnancy would signal a risk of having intrauterine growth restriction babies...

OBJECTIVE: Preeclampsia generally occurs in first pregnancies and tends not to recur when the interpregnancy interval (IPI) is short. We hypothesized that, in women experiencing preeclampsia in their first pregnancy, the difference in mean arterial pressure (MAP) across pregnancy between their index and subsequent pregnancy would be inversely associated with the length of time between pregnancies and that the interval between pregnancies will be directly associated with the likelihood of preeclampsia recurrence...

OBJECTIVES: Preterm premature rupture of membranes (PPROM) is a major contributor to overall preterm birth (PTB) rates. A short interpregnancy interval (IPI) is a well-known risk factor for PTB. It is unknown if a short IPI specifically affects the risk of developing PPROM in a subsequent pregnancy. We sought to determine the association between IPI and the risk of PPROM in a subsequent pregnancy. METHODS: A retrospective cohort study using the Missouri birth certificate database of singleton births from 2003 to 2013 was conducted...

BACKGROUND: Being overweight is an important risk factor for Gestational Diabetes Mellitus (GDM), but the underlying mechanisms are not understood. Weight change between pregnancies has been suggested to be an independent mechanism behind GDM. We assessed the risk for GDM in second pregnancy by change in Body Mass Index (BMI) from first to second pregnancy and whether BMI and gestational weight gain modified the risk. METHODS AND FINDINGS: In this observational cohort, we included 24,198 mothers and their 2 first pregnancies in data from the Medical Birth Registry of Norway (2006-2014)...

OBJECTIVE: Congenital anomalies are a serious public health issue, and relatively few modifiable risk factors have been identified. Our objective was to investigate one such potential risk factor, the interpregnancy interval (IPI). METHODS: We conducted a secondary analysis of data housed at the Manitoba Centre for Health Policy. In-hospital live births and stillbirths of at least 20 weeks' gestation were identified, and consecutive births to the same mother were grouped into sibling pairs to calculate the IPI for the younger siblings of each pair...

BACKGROUND: Anemia is a condition in which the number of red blood cells or their oxygen-carrying capacity is insufficient to meet physiologic needs, which varies by age, sex, altitude, smoking, and pregnancy status. The study aim is to determine the prevalence and factors associated with anemia among pregnant women attending a hospital in southern Ethiopia using a structured interview administered questionnaire. METHODS: Facility-based cross-sectional study was conducted from March 01-April 30 2015 at Butajira General Hospital, Ethiopia...
