AB Psychological intimate partner violence (IPV), a global public health problem, afects mothersduring pregnancy. We evaluated its relationship with preterm birth. We established a cohort of 779consecutive mothers receiving antenatal care and giving birth in 15 public hospitals in Spain. Trainedmidwives collected IPV data using the Index of Spouse Abuse validated in the Spanish language.Preterm was defned as birth before 37 completed weeks of gestation. Gestational age was estimatedby early ultrasound. With multivariate logistic regression we estimated the relative association of IPVwith preterm birth as adjusted odds ratios (AOR), with 95% confdence intervals (CI). In propensityscore analysis, using weighting by inverse probability of exposure to IPV, the whole sample was usedfor estimating the absolute diference in probability of preterm amongst ofspring born to motherswith and without IPV. Socio-demographic and other pregnancy characteristics served as covariatesin both analyses. Preterm occurred in 57 (7.3%) pregnancies. Psychological IPV, experienced by151 (21%) mothers, was associated with preterm birth (11.9% vs 6.5%; AOR= 2.4; 95% CI = 1.1–5.0;p = 0.01). The absolute preterm diference in psychological IPV compared to normal was 0.08 (95%CI = 0.01–0.16; p = 0.04). The probability of preterm birth was 8% higher on average in women withpsychological IPV during pregnancy. As our analysis controlled for selection bias, our fndings givecredence to a causal inference. Screening and management for psychological IPV during pregnancy isan important step in antenatal care to prevent preterm birth.
