Comparison of skinfold thicknesses measured in childhood and again 15 years later in 318 male and 303 female subjects disclosed only a moderate relation between the two measurements. Where adult fatness could be predicted from combinations of skinfold thicknesses in childhood the accuracy in 95% of cases lay at the mean between +/- 8% and +/- 18% according to age and sex.
In a study of 256 families, among whom were twins, midparent-adult son correlations for height, weight, and combined skinfold measurements were 0.67, 0.47, and 0.23 respectively. The corresponding midparent-adult daughter correlations were 0.63, 0.42, and 0.24. Midparent-growing offspring correlations were highest for height, less for weight, and insignificant for combined skinfold measurements. These data and the resemblances found between twins and siblings led us to conclude that there is a significant genetic contribution to the variation of height and weight, but that body fatness appears largely to be determined by environmental factors.
