Summary

We have analyzed the degree of familial resemblance for a group of variables estimating the body fatness in a sample of 1350 biological siblings (685 boys and 665 girls) from the Biscay province. Correlations between siblings were estimated through maximum-likelihood methodology described by Rao et al (1982) using MLECOR program for PC, after a fitting for the sex and age the analyzed anthropometric variables (Model 1) and after considering the different environmental variables shared by all the members of the sibship (Model 2). The results show that it does not exist a link to sex for the studied variables and that the values of correlation are similar for both Models. In general, skin folds and BMI (Body Mass Index) have a higher degree of familial similarity that Livi index and CFR (Centripetal Fat Ratio), this last indicating the patterning of body fat.
