Information on pregnancy intention is often gathered retrospectively (after the birth of the child). This paper investigated whether retrospective assessment of pregnancy intention leads to biased estimates of the consequences or extent of unintended fertility. Comparison is made between pregnancy intentions ascertained during pregnancy or after birth in the National Longitudinal Survey of Youth. Such comparisons are found to be biased by selective recognition or acknowledgement or pregnancy. The longitudinal feature of the data is used to determine actual pregnancy status at interview, which in turn is used as an instrumental variable for prospective (versus retrospective) reporting of pregnancy intention. After correction for selective pregnancy recognition, there is no evidence that retrospective assessment of pregnancy intention produces misleading estimates of either the number of the consequences of unintended births. This finding is supported by additional analysis of a small subsample for which pregnancy intention information was collected both during pregnancy and after delivery.

Information on pregnancy intention is often gathered retrospectively (after the birth of a child). This article investigates whether the retrospective assessment of pregnancy intention leads to biased estimates of the extent or consequences of unintended fertility. Comparisons are made between pregnancy intentions ascertained during pregnancy and after birth using data from the National Longitudinal Survey of Youth. To address the bias caused by selective recognition or acknowledgment of pregnancy, we used the longitudinal feature of the data to determine actual pregnancy status at the time of interviews, which, in turn, was used as an instrumental variable for the retrospective (versus prospective) reporting of pregnancy intention. After correction for selective pregnancy recognition, we found no evidence that the retrospective assessment of pregnancy intention produces misleading estimates of either the number or the consequences of unintended births. This finding is supported by additional analyses of a small subsample of women for whom information on pregnancy intention was collected both during pregnancy and after birth.

Objectives: Our objectives were to characterize the stability of pregnancy intention and to examine whether stability is associated with the timing of prenatal care initiation, smoking during pregnancy, and breastfeeding. Methods: We use a sample of women from the National Longitudinal Survey of Youth (NLSY) for whom information on pregnancy intention was collected both during pregnancy and after delivery. In bivariate analyses we compare outcomes and characteristics of women whose pregnancy intention changed between the prenatal and postpartum periods. With multivariate methods, we analyze the correlates of switching pregnancy intention as well as the association between switching and maternal behaviors. Results: Women whose pregnancy intention changes between the two assessments are similar in marital status and socioeconomic background to those who report both during pregnancy and after delivery that the pregnancy is unintended. Disagreement during pregnancy between the parents' pregnancy intentions is the most important predictor of instability in the mother's pregnancy intention. Effects of unintended pregnancy on the timing of initiation of prenatal care, smoking during pregnancy, and breastfeeding based on reports after delivery are smaller than those based on reports during pregnancy, although differences are not statistically significant. Adverse effects of unintended pregnancy are greater when pregnancies reported by the mother to be unintended at either assessment are combined into a single category for unintended pregnancy. Conclusion: Unstable pregnancy intention may be a marker for adverse maternal behaviors related to infant health.

In this paper, we use data from the National Longitudinal Survey of Youth to investigate the empirical link between unintended pregnancy and child health and development. An important contribution of our study is the use of information on siblings to control for unmeasured factors that may confound estimates of the effect of pregnancy intentions on infant and child outcomes. Results from our study indicate that unwanted pregnancy is associated with prenatal and postpartum maternal behaviors that adversely affect infant and child health, but that unwanted pregnancy has little association with birth weight and child cognitive outcomes. Estimates of the association between unwanted pregnancy and maternal behaviors were greatly reduced after controls for unmeasured family background were included in the model. Our results also indicate that there are no significant differences in maternal behaviors or child outcomes between mistimed and wanted pregnancies.

CONTEXT: Despite the well-established literature on couples' pregnancy intention and on the consequences of unintended pregnancy, the effects of parents' disagreement in fertility intentions has not been explored. Parental disagreement in pregnancy intention,as well as a father's pregnancy intention, may affect infant health.

RESULTS: Infants whose conception was intended by their mother but not their father are at elevated risk of adverse health events. When a pregnancy was not intended by the mother, the risks are higher than they are if both parents intended the pregnancy, but they differ little according to the father's intention. Thus, it may be useful to classify pregnancies as intended by both parents or not intended by at least one. In comparisons of siblings, unintended fertility (so defined) is associated with delayed prenatal care and reduced initiation of breastfeeding.

CONCLUSION: Information on both parent's fertility intentions is needed to identify infants at risk of adverse health and developmental outcomes.

Unintended Pregnancy and the Consequences of Non-Marital Childbearing

We estimate consequences of non-marital childbearing for infant health and child development, including the first estimates of these effects based on comparisons of siblings or first cousins. We also estimate effects of non-marital births by treating non-martial births that result from unintended pregnancies as exogenously determined. To bolster the case for exogeneity, in some models we use information on the availability of abortion services and indicators of state child support policies and enforcement as instrumental variables for pregnancy intention and marital status. Estimates from models with standard controls for mother's family background suggest that non-marital childbearing delays prenatal care initiation, lowers birth weight, increases smoking during pregnancy, reduces breastfeeding, and, according to several indicators, adversely affects child development. However, comparisons of siblings and first cousins suggest that these estimates exaggerate the adverse consequences of non-marital childbearing for children. Evidence of substantial adverse effects remains in comparisons of siblings and first cousins in two cases: elevated risks of smoking during pregnancy among divorced mothers, and reduced breastfeeding among never married mothers. Evidence for an effect of non-marital childbearing on child development is weaker.
