MONTOYA-RESTREPO, Nora E  and  CORREA-MORALES, Juan C. Birth-weight curves. Rev. salud pública [online]. 2007, vol.9, n.1, pp.1-10. ISSN 0124-0064.

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.
