[Saarland Growth Study: analyses of body composition of children, aged 3 to 11 years. Measurement of height, weight, girth (abdomen, upper arm, calf) and skinfolds (triceps, biceps, subscapular,suprailiacal, abdominal) and bioelectric impedance (BIA)].
This study aimed to set up current reference charts of anthropometric data in the Saarland. Only national and international data were available to be compared but no former Saarland charts could be found. In the period between 1994 and 1995 we investigated children of 3 to 11 years in a cross-sectional study. Therefore we measured body height, weight, circumferences, skinfolds and bioelectrical impedance (BIA). No significant gender differences were found for body height and weight. Boys of all groups of age showed bigger abdominal circumferences than girls of the same age. On the other hand upper-arm and calf-girth of younger girls were larger than that from boys. In higher age groups circumferences become rather equal. The skinfolds of Saarland girls are thicker than those of boys. The urban rural comparison indicated no significant differences. Nor was any social divergence found among the aforementioned parameters. Regarding height Saarland children are seen to be similar or somewhat shorter than those examined in national or international studies. By the way, in higher percentiles the children in our study were heavier. Thus high BMI values of our study are bigger compared with former studies. According to the definition of obesity by the ECOG almost 20 to 30% of our children are obese. The older children become the higher is the percentage of obesity. Comparing girls and boys, bioelectrical impedance shows higher values for girls. In higher age classes resistance levels gets smaller, in boys more so than in girls. Body fat estimated by a formula based on BIA test parameters yielded negative values. So we propose the use of sex- and age-specific raw charts of BIA test parameters.
