ABSTRACT

The aim of this work was to compare the nutritional classification of pregnant women and their predictive value for the low birth weight, using the criteria of the Ministry of health (Rosso-Mardones curves) with the curves developed at the Department of Nutrition of the Faculty of Medicine and the body mass index. One thousand eight hundred four pregnancy women of the Metropolitan Region, that were devoid of factors affecting birth weight, were studied retrospectively. Initial and final nutritional status was calculated according to the three criteria in study. Results showed that 47 to 75 percent of women classified as undernourished using Rosso-Mardones curves, were normal according to the curves of the Department of Nutrition and body mass index. Rosso-Mardones curves had the lower predictive value, relative risk and risk attributable to maternal nutritional deficit, for low birth weight. Also these curves showed a higher of obesity and a low predictive value for macrosomia. It is concluded that the curves used by the Ministry of Health must be revised

ABSTRACT

Se realizó un estudio prospectivo en un grupo de 25 embarazadas adolescentes a las que se les practicó una determinación única de la relación sístole-diástole (S/D) con doppler continuo de arterias arcuatas a ambos lados del útero desde la semana 16 de amenorrea en adelante. Se estableció la relación entre los resultados de la velocimetría doppler y el peso del recién nacido (RN). Hubo 7 RN pequeños para la edad gestacional (PEG). La sensibilidad del método fue 94,4%, la especificidad 57,1%, el valor predictivo positivo 80,0% y el valor predictivo negativo 85,0%. Se destaca la importancia de la determinación de ambas arcuatas y de la influencia de la ubicación placentaria en los resultados

ABSTRACT

1. Se presenta el test de Estimulación Manual como test de screening fetal. 2. Se analiza su sensibilidad, especificidad, falsos negativos y positivos respecto del registro basal no estresante. 3. Se encuentra una alta sensibilidad del método respecto al registro basal no estresante (100%) con una buena especificidad (98%). 4. Dados los antecedentes presentados se recomienda su uso a nivel primario de atención de salud en aquellos casos en que los métodos tradicionalmente aceptados para evaluar la unidad feto placentaria están ausentes
