Relationship of weight gain in infancy to subcutaneous fat and relative weight at 10 1/2 yr of age

Abstract

In a representative sample of 895 schoolchildren, aged between 9 yrs 10 mths and 11 yrs 2 mths, the risk of being overweight or obese was compared between those who had gained weight rapidly during infancy and those whose weight gain had been normal. A substantially increased risk ratio was found only in boys for whom a correlation analysis showed that the total weight gain during the first year of life was associated with the total body mass in relation to height, more or less independently of the degree of fatness at 10 1/2 yr of age. In girls, a direct but very weak association was found between weight gain in infancy and the degree of fatness at 10 1/2 yrs. The implications of these findings with respect to etiology and the possibilities of prevention are briefly discussed.
