ABSTRACT
INTRODUCTION:
Brazil is integrated into the global context of population displacement. Since 2018, the influx of Venezuelans has become the primary migratory wave, with significant female participation, which points to the importance of reproductive health care.
OBJECTIVE:
To analyze changes in the characteristics of mothers, pregnancy, childbirth, and newborns of Venezuelan migrants in São Paulo city, Brazil, comparing the periods before and after 2018 and contrasting with the Brazilian population.
METHODS:
Cross-sectional study was conducted using data from the Live Birth Information System (SINASC). Venezuelan mothers' characteristics were compared across two periods (2012–2017 and 2018–2025) and against the profile of Brazilian mothers using descriptive statistics.
RESULTS:
Between 2012 and 2025, 1,532 live births were registered. A significant increase occurred starting in 2018, with the volume being 11 times greater in the period 2018-2025 compared to previous years. Comparing 2012-2017 with 2018-2025, shifts occurred in: mothers aged 35 and over (32.5% vs. 11.7%), aged 15 to 19 (0.8% vs. 10.3%), white mothers (74.2% vs. 34.5%), higher education (84.2% vs. 31.0%), having a partner (81.7% vs. 52.0%), and primiparity (42.5% vs. 32.8%). Regarding care, ≥7 prenatal visits dropped (83.3% vs. 80.5%), as did first-trimester initiation (87.5% vs. 80.1%). Vaginal delivery predominated in 2012–2017 (66.7%), whereas cesarean sections rose in 2018–2025 (56.2%), similar to Brazilian rates (52.4%). Low birth weight (7.5% to 7.0%) and preterm births (9.2% to 8.7%) decreased slightly, remaining lower than Brazilian averages.
CONCLUSIONS:
Notable changes occurred in the sociodemographic profile of Venezuelan mothers and their live births following the 2018 migration flow. While there were improvements in prematurity and low birth weight outcomes, access to prenatal care declined and the frequency of cesarean sections increased.
