Factores asociados con lactancia materna exclusiva hasta el sexto mes en madres adolescentes. Medellin, 2010 / Factors associated with exclusive breastfeeding until the sixth month in teenage mothers. Medellin, 2010

Objetivo Determinar los factores asociados con la lactancia materna exclusiva hasta el sexto mes en madres adolescentes de los niveles I y II del SISBEN de la ciudad de Medellín. Métodos Se realizó un estudio de casos y controles con 323 madres adolescentes, 197 casos y 126 controles de la "Estrategia Buen Comienzo Había una Vez-BCHV" de Metrosalud y la Alcaldía de Medellín. Se aplicó estadística descriptiva para el análisis univariado. Se hizo un análisis de correspondencias. La comparación de variables cualitativas se realizó mediante tablas de contingencia y para las variables cuantitaivas con distribución no normal, U-Mann-Whitney. Para identificar los factores asociados con la lactancia materna exclusiva hasta el sexto mes, se utilizó regresión logística. Se realizaron curvas de Kapplan-Meier para la duración de la lactancia materna y las variables significativas en el modelo. Se calcularon los riesgos atribuibles en expuestos y riesgos atribuibles poblacionales. Resultados El 27,9 % de las madres adolescente lograron lactancia materna exclusiva hasta el sexto mes. La media de la edad de la madre fue de 17,56 años. En el análisis de regresión logística se encontró que el tiempo en la Estrategia, recibir educación después del nacimiento del niño y pertenecer a una familia nuclear están asociados a una mayor duración de lactancia materna. Conclusiones De acuerdo a los resultados encontrados en la población de madres adolescentes, la duración de la lactancia materna exclusiva puede extenderse haciendo énfasis en el tipo de educación y la continuidad en el programa.(AU)

Objective Ascertaining factors associated with exclusive breastfeeding until the sixth month in teenage mothers included in SISBEN system levels I and II in the city of Medellin. Methodology This was a case-control study which included 323 teenage mothers, involving 197 cases and 126 controls for the "Buen comienzo había una vez -BCHV" (good start) strategy. Univariate analysis involved using descriptive statistics; a correspondence analysis was also made. Qualitative variables were compared using contingency tables and the Mann-Whitney U test was used for quantitative variables having non-normal distribution. Logistic regressions was used to identify factors associated with exclusive breastfeeding until the sixth month. Kapplan-Meier curves were made for the duration of breastfeeding and for the significant variable in the model. The attributable risk to which the population was exposed was calculated, as were population attributable risks. Results 27.9% of teenage mothers in the sample managed exclusive breastfeeding until the sixth month. Average maternal age was 17.56 years. Logistic regression analysis revealed that the time spent involved in the strategy and education following the birth of a child for those belonging to a nuclear family were associated with a longer duration of breastfeeding. Conclusions The duration of exclusive breastfeeding in the teenage mother population could be extended, emphasizing continuity and the type of education received by being in the program.(AU)
