[The growth of the low-birth-weight neonate: assessment at 3 years].

: Follow-up studies of low-birth-weight (LBW) neonates have shown a high incidence of growth failure in the first years of life. We evaluated the growth attainment (weight, length and head circumference) in 182 LBW neonates discharged from our Intensive Care Unit between 1982-84 and included in a 3 years follow-up program. The aim of the study is to analyze the correlation between gestational age (GA) and subsequent growth failure. Neonates included in the study were divided in 4 groups (G) according to GA: I G or = 37 weeks of gestational age. Growth was evaluated at 40 weeks GA on the basis of Lubchenco and Battaglia centiles, and thereafter at 12, 24 and 36 months according to Scalamandre greeds. Subnormal weight (< 10 degrees centile) was still evident at 3 years of age in 16.7% of the most premature babies (group I), in 6.2% of babies born between 31 and 33 weeks GA (group II), in 7.1% of babies in group III and in 16.6% of LBW babies born at term of gestation (group IV). Length measurements were satisfactory in PT babies as none of them showed a length < 10 degrees centile by 24 months of age. On the contrary, in the term LBW neonates group 15.6% of babies still showed subnormal length at 3 years of age. Head circumference remained < 10 degrees centile in 16.6% in the I group, in 6.2% in the II group, 21% in the III group and 30% in the IV group.(ABSTRACT TRUNCATED AT 250 WORDS)
