Riesgo de morbilidad y mortalidad en recien nacidos de termino segun adecuacion del peso a la edad gestacional
1995
To assess neonatal prognosis in terms of hospitalizotion rates and mortaliry risks in term newborn infants from theirclassification as small (SGA), adequate (AGA) and low (LGA) birth weight for gestational age, by established chiieanintrauterine growth patterns, prospective information on 21 725 consecutive live term newborn infants (10% SGA;82% AGA and 8% LGA) was analized. Neonatal mortality and hospitalization rates in SGA (1% and 19%) wererespectively significantly higher (p < 0.001] than among AGA (0.13% and 10%) and LGA [0.23% and 13%). LGAinfants had significantly higher [p < 0.002) hospitalizction rates [13%] than those with AGA (10%). Risk of death(2.9%) and morbidity (41 ./%] were also significantly higher (p < 0.001 ( in SGA when their birth weight was belowpercentile 2 for gestational age than when it was between percentiles 2 and 10 |0.51% and 12% respectively}. AGAinfants had significantly lower risks than SGA between 2 and 10 percent;les [p < 0,001 and p < 0,002). Breakpointsin prognosis were found at 2, 10 and 90 of birth weight for gestational age percentiles.[Key words newborn , birth weight, gestational age, orogrosis.)
