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; p = 0.028) of completing ≥4 prenatal care visits compared to women with a regular status. Participants who reported an experience of denial of prenatal care at some point while Colombia ( n = 135; 15.2%) were 42.8% less likely (aPrR:0.57, 95%CI:0.45-0.73; p < 0.001) to complete ≥4 prenatal care visits than those with no reported denial of care. Urban area of residence was also independently associated with prenatal care, while there was no evidence of association with educational attainment, literacy levels, or year of migration. Prenatal care attendance is suboptimal among Venezuelan refugees and migrants, particularly those with an irregular migration status, despite that prenatal care became officially available in 2018 to all Venezuelans in Colombia regardless of migration status. Reducing barriers to prenatal care by ensuring Venezuelan refugees and migrants are aware of available care, are supported in navigating the health system, and by preventing discrimination and stigma in the health facility are critical to ensuring the health and wellbeing of displaced people, their children, and the surrounding community., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.

Background: Venezuela has experienced substantial human displacement since 2015. To inform HIV programmes and treatment distribution, we aimed to estimate HIV prevalence and associated indicators among migrants and refugees from Venezuela residing in Colombia, the largest receiving country., Methods: We conducted a biobehavioural, cross-sectional survey using respondent-driven sampling among Venezuelan people aged 18 years or older who had arrived in Colombia since 2015 and resided in four cities (ie, Bogotá, Soacha, Soledad, and Barranquilla). Participants completed sociobehavioural questionnaires and rapid HIV and syphilis screening with laboratory-based confirmatory testing, CD4 cell counts, and viral load quantification. Policies related to migration status affect access to insurance and HIV services in Colombia, as in many receiving countries, so we provided legal assistance and navigation support to participants with HIV for sustained access to treatment. Population-based estimates were weighted for the complex sampling design. Penalised multivariable logistic regression analysis was used to identify correlates of viral suppression (HIV-1 RNA <1000 copies per mL)., Findings: Between July 30, 2021, and Feb 5, 2022, 6506 participants were recruited through respondent-driven sampling, of whom 6221 were enrolled. 4046 (65·1%) of 6217 were cisgender women, 2124 (34·2%) of 6217 were cisgender men, and 47 (0·8%) of 6217 were transgender or non-binary people. 71 (1·1%) of all 6221 participants had laboratory-confirmed HIV infection, resulting in a weighted population HIV prevalence of 0·9% (95% CI 0·6-1·4). Among participants living with HIV, 34 (47·9%) of 71 had been previously diagnosed with HIV and 25 (35·7%) of 70 had viral suppression. Individuals with irregular migration status compared with individuals with regular migration status (adjusted odds ratio 0·3, 95% CI 0·1-0·9) and with a most recent HIV test in Colombia compared with a most recent test in Venezuela (0·2, 0·1-0·8) were less likely to have suppressed viral loads., Interpretation: HIV prevalence among migrants and refugees from Venezuela in Colombia suggests the HIV epidemic is close to being generalised, which could be addressed by the inclusion of migrants and refugees from Venezuela in local HIV services, improved access to and navigation support for HIV testing and care, and coordination with humanitarian programmes. There is an association between migration status and viral suppression, conferring both clinical and epidemiological implications. Therefore, legal support and access to insurance might lead to early detection of HIV and timely treatment for people with irregular migration status., Funding: US President's Emergency Plan for AIDS Relief through the US Centers for Disease Control and Prevention., Translation: For the Spanish translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2023 Elsevier Ltd.
