Weight gain in infancy and physical development between 7 and 10 1/2 yr of age

Abstract

Heights and weights were measured in 963 10 yr old children, whose weight data from the 1st yr of life were available. Rapid weight gain in infancy was arbitrarily defined on the basis of sex specific percentiles of weight gain at 4 mth intervals and from birth to 12 mth. In girls, no significant association between rapid weight gain in infancy and overweight at 10.5 yr was found. In boys, the association was significant for severe overweight (>120% of standard weight for height). An estimation of the possible benefit of an intervention program (food restriction in all male infants with rapid weight gain) showed, however, that at the very best 12% of the boys treated in this way could be expected to gain some benefit. The results of a correlation analysis between weight gain in infancy and change in height and relative weight between 7 and 10.5 yr suggested that the factors which determined weight gain in infancy were no longer operative at ages between 7 and 10.5 yr.
