Anthropometric changes in urban Sardinian children 7 to 10 years between 1975-1976 and 1996

This study is a comparison of several anthropometric variables in school children of the same age (7-10 years) and sex measured in two primary schools in Cagliari (Sardinia, Italy) at an interval of 20 years (1996 vs. 1975-1976). For both males and females of each age-class, there are significant differences in the following dimensions: weight, stature, estimated lower limb length, biacromial breadth, xiphoid chest circumference, xiphoid chest depth, and bicristal breadth, and also in relative sitting height, cephalic index, and facial index. The means of the relative sitting height, cephalic, and facial indexes are higher in the children measured in 1975-1976 than in those measured in 1996. There are no significant differences in sitting height and arm length. In addition, the estimated BMIs of the 1975-1976 sample are, on average, lower than those of the 1996 sample. The results suggest that urban Sardinian children sampled in 1996 are generally taller, heavier, and larger and have a longer head and wider face than their peers of 20 years earlier. The increase in stature is due more to an increase in lower limb length than in sitting height. Am J. Hum. Biol. 12:782-791, 2000. Copyright 2000 Wiley-Liss, Inc.
