ESCUDERO V, Luz Stella; PARRA S, Beatriz Elena y RESTREPO M, Sandra Lucía. SOCIODEMOGRAPHIC AND PREGNANCY ASPECTS ASSOCIATED WITH HEMOGLOBIN CONCENTRATION IN WOMEN FROM PUBLIC HOSPITALS IN MEDELLÍN. Rev. chil. nutr. [online]. 2011, vol.38, n.4, pp.429-437. ISSN 0717-7518. http://dx.doi.org/10.4067/S0717-75182011000400005.
Objective: To explore associations of sociodemographic and gestational factors with blood hemoglobin concentration. Methodology: Randomized sample of 336 pregnant women medical records from the Public Hospital Network in Medellín. Hemoglobin concentration, sociodemographic, and pregnancy data analyzed by Student T test, ANOVA and Pearsons correlation. Results: Average age of pregnant women was 24±6; 3.3%; 67.6% of them were high school graduates; 62.2% had permanent partners. Number of attendance to prenatal appointments was 6+1. Pregestacional weight was 54.4+8.2 kg; average hemoglobin concentration on the first trimester was 13.0±1.0 g/dl, 11.9±1.1 g/dl on the second, and 12.2±1.1 g/dl on the third. There was a significant difference in hemoglobin concentration based on pregestacional body mass index (BMI) (p=0,035), a significant correlation between first trimester hemoglobin concentration and pregestacional BMI (r=0.178, p=0.028), and also with third trimester hemoglobin concentration (r=0.356 andp=0.000). Conclusion: Pregestacional BMI was associated with hemoglobin concentration at the beginning and at the end of pregnancy.
