Objective:
This work was aimed at constructing curves relating birth-weight to gestational age; these can be used as a standard for the newborn in Colombia.
Method:
The curves were drawn up using birth-weights from pregnancies lasting 22-44 weeks. Three tables were drawn up; these are presented, along with their respective graphs. They were constructed using monotonic regression from the sample percentiles computed in strata defined by gender and the number of weeks.
Results:
Percentile curves were built for 5, 10, 25, 50, 75, 90 and 95% percentiles for the newborn in the form of tables and graphs.
Conclusions:
Constructing birth-weight curves from data pertaining to the target population led to better classification of the newborn.
