The prevalence of unplanned pregnancy ending in birth, associated factors, and health outcomes

What are associated factors of unplanned pregnancies ending in birth? 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. In Europe, the prevalence of unplanned pregnancy leading to birth varies. Unplanned pregnancy is more common among socially disadvantaged women, and associated with adverse pregnancy outcomes. In a cross-sectional study, 517 women were recruited from May through September 2015. Women were recruited from six hospitals in Flanders, Belgium. Data from self-report and medical records were collected during the first 5 days postpartum. The validated London Measure of Unplanned Pregnancy was used to collect data regarding pregnancy planning. Data were analysed with Mann-Whitney U tests, Kruskal-Wallis tests, and multiple linear regression analysis. The majority of the pregnancies (83%) ending in birth were planned, 15% were ambivalent, and 2% unplanned. Women who are multigravida (95% CI -0.30 to -0.02), less well educated (95% CI 0.07-0.85), single or having a non-cohabiting relationship (95% CI 0.01-2.53), having history of drug abuse (95% CI -2.07 to -0.35), and experiencing intimate partner violence (95% CI -3.82 to -1.59) tended to have a significantly higher risk of a less planned pregnancy. Less planned pregnancies were significantly associated with initially unwanted pregnancies (P
