Between 2015 and 2023, 7.3 million Venezuelans have been displaced globally. We aimed to assess uptake of and factors associated with prenatal care among Venezuelan refugees and migrants in Colombia. We analyzed data from a cross-sectional survey of 6,221 urban-residing adult Venezuelans who were displaced to Colombia between 2015 and 2022. Analyses were restricted to 917 women aged 18-49 years who reported at least one pregnancy and delivered in Colombia; of these, 564 (61.5%) women completed ≥4 prenatal care visits in their most recent pregnancy. We used general linear models with negative binomial regression to identify associations and estimate the adjusted prevalence ratios (aPrR) of variables associated with completing ≥4 prenatal care visits during last complete pregnancy (WHO's pre-2016 recommendations). Having an irregular migration status was independently associated with a 12% lower likelihood (aPrR:0.88, 95%CI:0.78-0.99;
