This study evaluated a group of 15 low-weight pregnant women, who underwent prenatal medical examinations at a City Health Center on the outskirts of Botucatu - SP, using the "Rosso Curve", and compared them with a group of 8 normal-weight pregnant women, also screened by the same institution at the same prenatal service. We verified that the children born from normal-weight pregnant women weighed an average 118g more than those of low-weight pregnant women. Independent of the mother's weight, those born from mothers whose height was greater than 155cm and were non-smokers weighed more. Pregnant women of normal weight had, on average, an additional 2 weeks of pregnancy: Amongst those born of low-weight pregnant women, we noted a connection between medium birth weight and an increase on the uterine height curve x gestational age. There was no connection between maternal anemia and interpartal intervals less than to 2 years and birth weight.
