Fuentes genéticas y ambientales en la transmisión familiar del índice de Quetelet

ABSTRACT: A cross-sectional sample of 1024 individuals (115 fathers, 257 mothers, 309 sons and 343 daughters) of 442 nuclear families living in the province of Biscay (Basque Country) was studied. The aim was the estimation of the transmissible (genetic and cultural) and non-transmissible components that are acting on the familial resemblance for the Quetelet’s index, through a BETA model of path analysis. In addition, several models of familial transmissible were tested, in order to find out what was that best fitting the transmission from parents to their children, and to estimate the relative importance of the genetic, cultural transmitted and environmental non-transmitted factors have on the inheritance of this variable. The results have showed that the full model, which estimated 10 parameters, was the lest restrictive model that best fitted the Quetelet’s index transmission. Also, evidences of a possible maternal influence on this index, as well as estimations of the total transmissible component lower than those in the literature were found. However, we could not forget that these estimations are specific for each population.
