Changes of fat distribution were followed up in Czech and Slovak children from 1.5 to 15 years of age, using centrality indices, which relate the values of skinfolds on the trunk to the skinfolds on the extremities, head and neck. Up to 5 years of age, subcutaneous fat was deposited relatively more on the extremities, head and neck than on the trunk, which was expressed by lower values of the centrality indices. After the age of 5 years, the accumulation of subcutaneous fat was greater on the trunk, which was also expressed by higher values of the centrality indices. The comparison of the individual indices revealed in both genders a relatively higher amount of subcutaneous fat on the trunk in boys until 12 years of age. During puberty subcutaneous fat over triceps and on the forearm was reduced. In girls the deposition of the subcutaneous fat was relatively greater at different sites of the trunk than in boys, with the exception of the age of 14-15 years. The deposition of subcutaneous fat was greater on the trunk than on the head (cheek) and on the extremities in Czech compared to Slovak children, except for 12-year-old girls. During the period between the fifties and the seventies of the last century, in Czech children, especially in girls, the deposition of subcutaneous fat on the trunk was relatively smaller than on other parts of the body surface, which was expressed by the reduction of the centrality indices. Index 12 was therefore considered as the most valuable for the characterization of fat distribution on the body surface.
