Longitudinal follow-up of growth in children born small for gestational age.

• Postnatal growth was followed in a population-based group of 123 small-for-gestational-age (SGA, birth weight < -2 SD) children (66 boys and 57 girls) to four years of age in order to determine the incidence and time of catch-up growth. Gestational age was determined by ultrasound in gestational weeks 16-17 in all pregnancies, thus eliminating the problem of distinguishing between SGA and preterm infants. Infants with well-defined causes for slow growth rate, i.e. those infants with chromosomal disorders, severe malformations, intrauterine viral infections or cerebral palsy, were excluded. The boys showed an extremely fast weight catch-up, 85% of them reaching weights greater than -2 SD at the age of three months and remaining above this level to the end of the study period. Such a fast catch-up growth was observed in only two-thirds of the girls, but at four years of age 85% of the girls were also above -2 SD. Length catch-up was more gradual than weight catch-up. Of the boys, 54% had lengths below -2 SD at birth, 26% at 1 year of age, 22% at 2 years of age, 17% at 2.5 years of age and 11% (n = 8) at 4 years of age. Corresponding figures for girls were: 69% at birth, 28% at 1 year, 15% at 2 years, 12% at 2.5 years and 5% (n = 3) at 4 years. At 4 years of age, only six boys and three girls remained below -2 SD for both weight and height.(ABSTRACT TRUNCATED AT 250 WORDS)
