To explore the association between low birth weight and preterm birth with violence during pregnancy, we conducted a cross-sectional study by using the 2010 Colombian Demographic and Health Survey. We conducted bivariate analyses, binomial logistic regression, and stratified models by age, and 14,520 women were included. There was no association between violence and low birth weight. Nonetheless, an association with preterm birth in women aged over 35 was observed (OR 1.98, 95%CI 1.23, 3.17). Prenatal care appeared to be a protective factor for both outcomes. This research unexpectedly showed that supplementation with folic acid and iron was associated with preterm birth.
