We selected vulnerability indicators from sociodemographic data and tested the performance and risk association of multiple SVI models with any adverse outcome (preterm birth, gestational diabetes mellitus, pre\u2010eclampsia, small or large for gestational age, low 5\u2010min Apgar score, neonatal intubation, neonatal intensive care unit admission, fetal or neonatal death) using chi\u2010square tests, logistic regression, and receiver operating characteristic analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Advanced maternal age, non\u2010white ethnicity, and exclusive publicly funded antenatal care were the most consistent vulnerability predictors of adverse outcomes. The final three\u2010variable SVI demonstrated a significant dose\u2013response gradient, with maternal adverse outcomes increasing from 16.4% (no vulnerabilities) to 43.8% (3 vulnerabilities) and perinatal adverse outcomes rising from 22.1% to 35.6%. The model presented a sensitivity of 64.71%, a specificity of 42.56%, a positive predictive value of 47.46% and a negative predictive value of 60.07% for any adverse outcome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The three\u2010variable SVI offers a simple, reproducible, and context\u2010adapted screening tool for primary care.
