Over the same period, girls of similar age showed stature increases with a mean value of 2% for each 1 year age group and average mass increases of 11%. The magnitude of the secular increase declined with age from 12 to 17 years. Standard deviations for the 1940 data were not presented; hence, the statistical significance of any difference between mean values could not be established. The body mass index (BMI) estimates from 1940 were lower at all ages for both sexes than the actual BMI data from 1984. 0 1995 Wiley-Liss, Inc A great deal of evidence exists to show that relative to age, children today are taller and heavier, and mature earlier, than children of several decades ago (Malina, 1990).
