Increased stress, psychosocial problems, economic disadvantages, and lack of prenatal care are proposed to explain discrepancies in the outcome of unintended pregnancies. Studies of maternal intention and pregnancy outcomes have yielded varied results. Objective is to review studies of the risk of low birth weight (LBW)/preterm births (PTB) associated with unintended pregnancies ending in a live birth. We reviewed studies reporting on maternal intentions and outcomes from Medline, Embase… Expand
Maternal pregnancy intention and its association with low birthweight and pregnancy complications in Bangladesh: findings from a hospital-based study.
TLDR
Women with unintended pregnancies are at increased risk of producing LBW babies and experiencing complications during pregnancy, and maternal pregnancy intention should be addressed in interventions aimed to reduce maternal and child morbidity and mortality. Expand
Pregnancy Intention and Pregnancy Outcome: Systematic Review and Meta-Analysis
TLDR
There seems to be an increased risk of adverse pregnancy outcome in unintended pregnancies and there has been little improvement in either the quantity of evidence from low-income countries or in the quality of evidence generally. Expand
The prevalence of unplanned pregnancy ending in birth, associated factors, and health outcomes.
TLDR
Pregnancies that were less planned were associated with women of lower socio-economic status (SES), an unhealthier lifestyle before and during the pregnancy, more stress, and less social support. Expand
Short interpregnancy interval and poor fetal growth: Evaluating the role of pregnancy intention
TLDR
Findings suggest that previously observed associations between short interpregnancy interval and lower birthweight may reflect confounding by socio‐economic and/or other unmeasured confounders. Expand
Research : Pregnancy Effect of pregnancy planning on maternal and neonatal outcomes in women with Type 1 diabetes
Aims To assess the effect of pregnancy planning on maternal and neonatal outcomes in women with Type 1 diabetes. Methods Pregnancy planning was assessed retrospectively in a cohort of women whoExpand
Effects of Maternal Pregnancy Intention, Depressive Symptoms and Social Support on Risk of Low Birth Weight: A Prospective Study from Southwestern Ethiopia
TLDR
The relationship between antenatal depressive symptoms and LBW was mediated by the presence of social support, while the association between LBW and unwanted pregnancy remained after multivariable adjustment. Expand
Unplanned pregnancy and risk of maternal depression: secondary data analysis from a prospective pregnancy cohort
TLDR
UP is an independent risk factor for persistent depression, but not for postpartum depression, according to secondary analysis of data from a prospective cohort study with pregnant women recruited from 10 primary care clinics of the public sector in São Paulo, Brazil. Expand
The effect of pregnancy intention on maternal prenatal behaviours and parent and child health: results of an irish cohort study.
TLDR
While there was little evidence to suggest that pregnancy intention was associated with adverse neonatal outcomes or developmental delay independent of other covariates, there was strong evidence that intention status had a bearing on the mother's psychosocial health. Expand

OBJECTIVE To describe pregnancy intention and contraceptive use among women with a recent delivery that occurred at 35 weeks gestation or fewer and who were enrolled in a large-scale randomizedExpand
Risk factors associated with preterm birth among singletons following assisted reproductive technology in Australia 2007–2009–a population-based retrospective study
TLDR
Preterm birth rate is approximately one-and-a-half-fold higher in ART mothers than non-ART mothers albeit for singleton births after controlling for confounding factors, however, ART mothers were less subject to the adverse influence from socio-demographic factors than other singleton birth mothers.

Pregnancy Intention and Its Relationship to Birth and Maternal Outcomes
TLDR
Pregnancy intention, specifically unwanted and ambivalent, may be an indicator of increased risk for some poor birth and maternal outcomes and should be considered in interventions aimed at improving the health of the mother and child. Expand
Pregnancy intention and preterm birth: differential associations among a diverse population of women.
TLDR
In unadjusted results, pregnancy intention was associated with preterm birth among both whites and immigrant Latinas, but not among blacks or U.S.-born Latinas. Expand
Pregnancy intention and birth outcomes: does the relationship differ by age or race?
TLDR
Contrary to the hypothesis, an intended pregnancy at a young age was associated with a higher risk of poor birth outcomes. Expand

TLDR
In this study of a cohort of urban, clinic-attending, low-income, pregnant black women, unintended pregnancy had a statistically significant association with preterm birth. Expand

Pregnancy Intendedness, Maternal Psychosocial Factors and Preterm Birth
TLDR
Pregnancy intendedness remains an important concept in the reproductive health literature integrally tied to indicators of maternal mental health, but not necessarily to pregnancy outcomes. Expand
The effects of pregnancy planning status on birth outcomes and infant care.
TLDR
Knowing the planning status of a pregnancy can help identify women who may need support to engage in prenatal behaviors that are associated with healthy outcomes and appropriate infant care. Expand
Pregnancy wantedness and adverse pregnancy outcomes: differences by race and Medicaid status.
TLDR
Mothers of very low birth weight infants were significantly more likely than those who had a normal-weight baby to report that they had felt unhappy about the pregnancy, and odds ratios associating these two unwantedness categories with low-birth-weight babies were higher among Medicaid recipients than among women not receiving Medicaid.

Unintended pregnancy and low birthweight in Ecuador.
TLDR
Unwanted pregnancy, but not mistimed pregnancy, is associated with low birthweight in Ecuador, and further research is needed to understand the mechanism through which pregnancy intention status affects birthweight. Expand
Associations of intrauterine growth restriction among term infants and maternal pregnancy intendedness, initial happiness about being pregnant, and sense of control.
TLDR
Prenatal care programs should focus on known risk factors for intrauterine growth restriction, and research should continue to explore associations between psychosocial factors and IUGR. Expand
