Abstract
Adult height has increased around the world, especially in developed countries, probably due to the improvement in life conditions. To assess differences in women's height in two population samples of different socioeconomic status coming from the public and the private health system in Chile, and the influence of the year of birth on height. Data from 5,416 pregnant women attended in the public health system and 1,658 women attended in the private system, were analyzed. Among women attended in the private system, the association of maternal height with anthropometric indices of the newborn were also studied. Mean height difference in the two systems reached 3.78 cm. The correlation coefficient of maternal height and year of birth was significant although weak in the two health systems, but mean height differences between decades of birth were significant only in the public sector: 0.7 and 1 cm in each of the two most recent decades. Association of maternal height was significant although weak, with both weight and height at birth, controlling for newborn's sex. Socioeconomic factors influence maternal height. Maternal height has an influence on fetal growth.

Summary
Adult height has increased around the world, especially in developed countries, probably due to the improvement in life conditions. Los artículos publicados en los últimos quince años, y con información de la talla en mujeres embarazadas beneficiarias del sistema público de salud, señalan promedios entre 153,5 y 155 cm[6,7,8,9,10]. La información disponible sobre los resultados de la Encuesta Nacional de Salud (ENS) del año 2003, realizada en una muestra representativa de la población mayor de 17 años de todo el país, muestra un promedio de talla en mujeres de 155,6 cm[11]. El primer propósito de este estudio fue conocer los promedios de talla en muestras de mujeres embarazadas atendidas en los sistemas de salud público y privado. Que sólo pudo llevarse a cabo con los datos disponibles del sistema privado, fue estudiar la posible asociación de la talla materna con el peso y la talla del recién nacido, considerando la influencia del sexo
