OBJECTIVE: To assess the risks and trends of adverse pregnancy outcomes among mothers in common-law unions versus traditional marriage relationships. METHODS: We conducted a birth cohort-based study of all 720,586 births registered in Quebec for the years 1990 to 1997. RESULTS: The proportion of births to common-law mothers more than doubled from 20% in 1990 to 44% in 1997. Preterm birth, low birth weight, small for gestational age, and neonatal and postneonatal mortality rates increased… Expand
Adverse birth outcomes in relation to maternal marital and cohabitation status in Canada.
TLDR
In a nationally representative Canadian birth cohort, cohabiting and legally married women experienced similar birth outcomes, but most outcomes for single women were substantially worse. Expand
Impact of Marriage on Birth Outcomes: Pregnancy Risk Assessment Monitoring System, 2012–2014
TLDR
Marriage is associated with a lower risk of preterm delivery, small for gestational age infants, and neonatal intensive care unit admission and these differences persist even after correcting for potentially confounding socioeconomic factors. Expand
The Impact of Paternity and Marital Status on Low Birth Weight and Preterm Births
TLDR
Being unmarried and lack of established paternity appear to be significantly correlated with and may be important risk factors for preterm and low birth weight deliveries. Expand
Pregnancy outcome is associated with maternai marital status in Austria - even at the beginning
TLDR
The rate of preterm delivery and rate of low birth weight among term births were significantly higher among unmarried mothers in comparison to married mothers and the newborns of unmarried mothers were significantly lighter and shorter than those of married mothers. Expand
The Associations between Bridal Pregnancy and Obstetric Outcomes among Live Births in Korea: Population-Based Study
TLDR
Pregnancy outcomes among live births from bridal pregnancies are associated with higher risks for PTB and LBW in Korea and these outcomes were associated with a social disadvantage and particular risk factors. Expand
Pregnancy outcome is associated with maternal marital status in Austria--even at the beginning of the 21st century.
TLDR
The rate of preterm delivery and rate of low birth weight among term births were significantly higher among unmarried mothers in comparison to married mothers and the newborns of unmarried mothers were significantly lighter and shorter than those of married mothers. Expand
The Potential Contribution of Marital-Cohabitation Status to Racial, Ethnic, and Nativity Differentials in Birth Outcomes in Texas
TLDR
The results suggest that union status at birth is a very weak factor in accounting for disparities in birth outcomes, andDiffering patterns in union status did not account for the Black-White and Mexican Origin-White gaps in infant health outcomes. Expand
Missing paternal data and adverse birth outcomes in Canada.
TLDR
Estimates were robust to varying definitions of missing paternal information, based on the birth registration, census data, or both, and suggest that missing paternal data is a marker for increased risk of adverse birth outcomes, over and above maternal characteristics. Expand
Maternal marital status and the risk of stillbirth and infant death: a population-based cohort study on 40 million births in the United States.
TLDR
Nonmarital childbearing seems to be associated with an increased risk of fetal and infant death, including SIDS, and promoting access to care and targeting unmarried mothers-to-be with the goal of educating, increasing awareness, and providing resources for proper obstetrical and maternal care may be of great benefit to their pregnancies. Expand
The Effect of Prenatal Stress, Proxied by Marital and Paternity Status, on the Risk of Preterm Birth
TLDR
The adjusted effect of perceived prenatal stress differed with respect to parity (confirmed by statistically significant interactions between Marital-Father Data index levels and parity), with a higher magnitude of this effect noted among multiparous versus primiparous women. Expand

Marital status, cohabitation, and risk of preterm birth in Europe: where births outside marriage are common and uncommon.
TLDR
There is a significantly elevated risk of preterm birth associated with both cohabitation and single motherhood for women living in countries where fewer than 20 of births occur outside marriage, and there is no excess risk associated with marital status when out-of-marriage births are more common.

Association of Sociodemographic Variables With Risk for Very Preterm Birth in Twins
TLDR
Traditional sociodemographic risk factors were present for twin preterm birth, but mainly before 34 weeks' gestation, which indicates that dominant pathogenic mechanisms of early pre term birth in twin gestations are likely to be different from those causing later preterm twin birth. Expand
Maternal marital status as a risk factor for infant mortality.
The increased risk of infant mortality associated with single motherhood is neither consistent among social and demographic subgroups nor inevitable, according to data from national linked birth andExpand

TLDR
This study confirms prior work reporting an association of physical abuse during pregnancy with intrauterine growth retardation and, in addition, reports an association with antepartum hemorrhage and perinatal death. Expand

TLDR
The differential in infant mortality between social classes still exists, whereas the differential between sole and couple registrations has decreased, showing positive progress in the reduction of inequalities. Expand

TLDR
The differential in infant mortality between social classes still exists, whereas the differential between sole and couple registrations has decreased, showing positive progress in the reduction of inequalities. Expand
Exposure to tobacco smoke in utero and the risk of stillbirth and death in the first year of life.
TLDR
One in five stillbirths and 20% of all infant deaths in a population with 30% pregnant smokers could be avoided if all pregnant smokers stopped smoking by the sixteenth week of gestation. Expand
Maternal education and fetal and infant mortality in Quebec. Fetal and Infant Mortality Study Group of the Canadian Perinatal Surveillance System.
TLDR
Fetal and infant mortality rates were greater for the offspring of mothers with less than 12 years of education, compared with mothers with at least 14 years, even after adjusting for maternal age, parity, marital status and infant's sex. Expand
Prepregnancy weight and the risk of adverse pregnancy outcomes.
TLDR
Higher maternal weight before pregnancy increases the risk of late fetal death, although it protects against the delivery of a small-for-gestational-age infant. Expand

TLDR
There is a need for future research on the effect of maternal work, prenatal care, and certain vitamin and mineral deficiencies on intrauterine growth, and theeffect of genital tract infection, prenatal Care, maternal employment, stress and anxiety on prematurity. Expand
