Abstract
Objective: To observe whether there exists a characteristic body fat mass at pubertal onset. Design: Longitudinal clinical follow-up (between ages of 10 and 15 y) with an annual visit in a sample of 469 children. They were grouped according to age of purbertal onset: boys with pubertal onset at the ages of 11 (n=59), 12 (n=88), 13 n=89) and 14 y (n=46), and girls with pubertal onset at the age of 10 (n=68), 11 (n=66), 12 (n=37) and 13 (n=16). Methods: Height, weight, upper arm circumference and four skinfold thicknesses were recorded annually. In boys testicular volume index was measured, and genital development was assessed on the Tanner scale; in girls mammary development was measured also using the Tanner scale. The sum of four skinfolds, body mass index, upper arm fat estimate and percentage body fat were calculated. Results: Boys presented a positive relation between the age of pubertal onset and body mass index (PPP=NS) or in boys (P=NS). The characteristic adiposity of the puberty onset is progressively acquired during the previous years in all the groups. Conclusions: Puberty seems to begin with a characteristic subcutaneous body fat mass that is independent of the age of onset. This study supports the hypothesis of a close link between maturation and the development of an energy store in the form of adipose tissue in both sexes.
