Introduccion: la muerte fetal es un importante problema de salud publica. Es necesario establecer la magnitud con que se asocia a diferentes factores, para desarrollar planes de prevencion. Objetivo: estimar la asociacion entre muerte fetal y grupos etarios maternos. Materiales y metodos : estudio de casos y controles. Se consideraron todas las maternas que tuvieron parto en una institucion de alta complejidad de atencion sanitaria en Cartagena, Colombia, durante el ano 2012. Se conformaron tres grupos de acuerdo con la edad materna. Grupo 1 o mujeres adolescentes (igual o menos de 19 anos de edad). Grupo 2 o mujeres con edad materna avanzada (igual o mas de 35 anos de edad. Grupo 3 o mujeres con edad materna intermedia (20-34 anos de edad). Se describen las variables continuas por medio de medidas de tendencia central y de dispersion, se determinaron IC95% para las edades de las pacientes y variables categoricas por medio de proporciones. Se calcularon los OR y sus intervalos. Resultados: tuvieron 3939 mujeres: 7.9% adolescentes y 12.9% gestantes con edad avanzada. Se presentaron 27 casos de muerte fetal para una tasa de 6.9 x 1000 nacidos vivos. Para el grupo de mujeres con edad materna avanzada se obtuvo OR: 1.54 [IC95%: 0.21-5.24]. Para el grupo de adolescentes se obtuvo OR: 1.26 [IC95%: 0.30-3.68]. Conclusiones: las edades extremas de la vida reproductiva no se asociaron significativamente a elevacion en el riesgo de muerte fetal.

It is necessary to establish the magnitude with which it is associated to different factors, to develop prevention plans. Objective: To estimate the association between fetal death and maternal age groups. Methods: Case-control study. All mothers who had childbirth in a high-complexity level institution of healthcare in Cartagena, Colombia during 2012 were considered. Three groups were defined according to the maternal age. Group #1 or adolescent women (Less than or equal to 19 years of age), Group #2 or women with advanced maternal age (Greater than or equal to 35 years of age) and Group #3 or women with intermediate maternal age (20-34 years of age). Continuous variables were described by measures of central tendency and measures of dispersion; confidence intervals of 95% were determined for the ages of the patients and categorical variables were defined by proportions. OR values and the confidence intervals of 95% were calculated. Results: 3939 women had childbirth. 7.9% of them were adolescent women and 12.9% were pregnant women with advanced age. 27 cases of fetal death occurred, for a tax of 6.9 x 1000 live births. For the group of women with advanced maternal age an OR: 1.54 [CI95% 0.21-5.24] was obtained and for the group of adolescent women an OR: 1.26 [CI95% 0.30-3.68] was found. Conclusions: extreme ages of the reproductive life do not associate significantly to elevation in the risk of fetal death.
