Objective. To determine the relationship between anemia and the threat of preterm birth in pregnant women at the Carlos Lanfranco La Hoz Hospital in the period 2020-2021. Materials and Methods. An observational, retrospective analytical case and control study was carried out in a population that consisted of all patients hospitalized in the gynecology and obstetrics service with a total population of 240, of which 120 pregnant women with preterm birth were cases and 120 with normal deliveries were controls. Results. The independent variable of anemia represented 36.7% of the total number of patients and the percentages of anemia with respect to the case groups was 48.3% and 28.3% in the controls, respectively. The multivariate analysis shows that anemia (OR: 2.24; CI: 95% 1.26-3.97; p:0.006) and insufficient prenatal controls (OR: 2.33; CI: 95% 1.32-4 .1; p:0.003) are significantly associated with the threat of preterm birth, adjusted to the variable’s history of premature birth, insufficient prenatal controls, age, obesity and being multi-pregnant. On the contrary, there was no significant association for the variables of obesity, history of preterm birth, age and multi-pregnancy. Conclusions. Having anemia and insufficient prenatal controls proved to be an important risk factor for developing threatened preterm birth.
