          Abstract

          En Colombia, el embarazo adolescente es un problema de salud pública, con serias implicaciones en la salud y nutrición del binomio madre-hijo. El objetivo del estudio fue evaluar características sociodemográficas, económicas, de seguridad alimentaria, de salud y el estado nutricional por antropometría en adolescentes en el tercer trimestre de embarazo y asociar estos factores con el peso de los recién nacidos. Se realizó un estudio analítico de corte transversal con 294 embarazadas (semana 27-40) del programa de control prenatal de la Red Pública Hospitalaria de Medellín-Colombia. Se buscó asociación del peso al nacer del neonato con las variables explicativas. El bajo peso en embarazadas se presentó en mayor proporción en adolescentes cuyas familias devengaron menos de un Salario Mínimo Mensual -SMMLV-, en las que tenían 15 años o menos y con edad ginecológica menor de cinco años. La mayor proporción de pequeños para la edad gestacional se presentó en adolescentes con infecciones, bajo peso gestacional e ingresos menores a un SMMLV. Devengar menos de un SMMLV disminuye 118 gramos el peso del recién nacido (IC95%:-2,5a-234,7) y por cada kilogramo que aumentó el peso pregestacional materno, el peso al nacer aumentó 10,3 g (IC95%: 2,0 - 18,5). Los ingresos económicos inferiores a un SMMLV se asociaron con bajo peso materno y con recién nacidos pequeños para la edad gestacional. El peso pregestacional, el índice de masa corporal bajo en tercer trimestre de gestación y la presencia de infecciones urinarias y/o vaginales de la madre se asociaron con recién nacidos pequeños para la edad gestacional.

          In Colombia, adolescent pregnancy is a public health problem, with serious implications for the health and nutrition of the binomial mother-child. Objective: assess socio-demographic, economic, food security, health and maternal nutritional status characteristics by anthropometric measures in a group of pregnant adolescents in Medellin-Colombia on their third trimester of pregnancy and associate them with the newborns weight. Methods and materials: A cross sectional analytical study was made with 294 pregnant women (week 27 to 40), who participating in prenatal control program of the public hospital network in Medellin-Colombia. We sought Association of weight at birth with the explanatory variables. Results: underweight in pregnant women was presented in families that had lower income wages than the Standard Minimum Wage Income - SMWI-, adolescents who were younger than 15 years old and those who had a gynecological age less than five years. In newborns, the highest proportion of small children for pregnancy age was found in mothers who presented infections, low pregnancy weight and low family income less than the minimum wage. For those whose earnings was less than the minimum income the newborn weight decreased 118g (CI95%:-2,5 a - 234,7), in addition, for each kilogram that increased the prepregnancy weight, newborn weight increased in 10,26g (CI95%:1,98 a -18,5). Conclusions: low-weight pregnancy and low-weight newborns are associated with low family income. Pre-pregnancy weight, body mass index in the third trimester of pregnancy and mother`s presence of urinary tract and vaginal infections were associated with the newborn´s weight.
