Through the appreciated logistic regression function the possibilities of low weight at birth were calculated in the estimation sample, and that empiric distribution was fragmented in tertils to scrutinize zones allowing classifying pregnant women as low, medium and high risk of low weight births.

Results:

85.7% of the pregnant women showed low probability of low birth weight. 60.4% of them was classified as patient with a high probability of low birth weight, and most of the patients classified as of medium risk of low birth weight; 11 patients were not adequately classified by the prognostic index.

Conclusions:
