This study aimed to determine the association between sociodemographic factors and the pre-birth monitoring associated with perinatal mortality in pregnant women from Colombia. Methods: this was a cross-sectional analysis from the 2010 Colombian Demographic and Health Survey and the National Nutritional Survey that included 14 754 pregnant women between 13 and 44 years old. Sociodemographic factors included: new born sex, geographic region, socioeconomic status (SISBEN), pre-birth monitoring (weight control, uterus height, blood pressure, fetal cardiac activity, biochemistry essays, urine analysis) and the supplementation of iron, calcium and folic acid, were collected by structured questionnaire. Associations were established through multivariable and binary regression models. Results: sociodemographic factors such as living in high-density cities, pacific and western regions and low socioeconomic status (SISBEN I) showed a highest perinatal mortality with rates of 1.7%, 1.5%, 1.4% and 1.4%, respectively. After adjustment by new born sex, geographic region and SISBEN score, an adequate monitoring of weight control (OR = 5.12), blood pressure (OR = 5.18), biochemistry essays (OR = 2.19), supplementation of iron (OR = 2.09), calcium (OR=1.73) and folic acid (OR = 2.73) were associated as facilitators of perinatal mortality. Conclusions: perinatal mortality is determined by the sociodemographic factors and pre-birth follow-up included in this study. Government and decision makers can take these results to garbage actions aiming to improve pregnancy monitoring.
