| description | To determine the association and its magnitude between prematurity and anemia in women in their third trimester of pregnancy and at labor. An incident case - control study was conducted using 2 controls per case. Data was obtained in a tertiary hospital in Valencia, Venezuela. A total of 543 women who delivered between May and December 1996 entered into the study. Women having a preterm delivery, less than 37 weeks of gestation at delivery, were defined as cases (n=181). Anemia was defined according to WHO as Hb less than 11g/dL. Logistic regression was used to analyze the data and likelihood ratio test was done for model comparison. Maternal anemia was found to be significantly associated with prematurity (Odds Ratio: 1.70; 95%CI = 1.18 to 2.57 P = .001), after adjusting for Placental Abruption, PROM, Previous Premature Labor, Prenatal Care Visits, and Uterine Bleeding during more than one trimester. Maternal anemia at the end of the third trimester of pregnancy, at labor, was associated with an increased risk of prematurity<br>Asociación entre prematuridad y anemia materna al final del tercer trimestre en embarazadas venezolanas. El objetivo de este estudio fue determinar la asociación y su magnitud entre prematuridad y anemia materna al final del tercer trimestre del embarazo ( en el momento del trabajo de parto). Estudio de Casos y Controles (2 controles por caso). Entre mayo y diciembre de 1996 fueron estudiadas 543 embarazadas al final del tercer trimestre gestacional y en trabajo de parto. Los casos fueron 181. La anemia fue definida como la presencia de Hb < de 11g/dL (OMS). Los datos fueron analizados mediante regresión logística. Para evaluar la significancia de los modelos reducidos se utilizó la prueba de razón verosimilitud.Se determinó que la prematuridad está asociada significativamente con anemia materna (OR: 1.70 IC95% = 1.18 a 2.57, P = .001), después de ajustar por desprendimiento placentario, ruptura prematura de membranas _ RPM - partos prematuros previos, menos de 5 visitas prenatales y sangramiento uterino en más de un trimestre. La anemia materna al final del tercer trimestre está asociada con un mayor riesgo de prematuridad |
