|Zusammenfassung||Objective: To analyse the importance of intra-abdominal fat and its relation with anthropometric parameters, blood pressure and plasma cholesterol levels in German primary school students. To examine the prevalence of cardiovascular risk factors in this sample.
Design: Cross-sectional assessment in the context of a randomized intervention study. The data were found in 2006.
Subjects: 1038 German school children aged 6 - 9 years.
Methods: During a physical examination height, weight, skinfold thicknesses, circumferences and blood pressure were measured. Intra-abdominal depth was measured by ultrasound. Plasma levels of total cholesterol, high-density cholesterol and low-density cholesterol were determined.
Results: Age-, height- and sex-specific percentiles of intra-abdominal depth were established. Intra-abdominal depth was significantly correlated with anthropometric parameters such as height, weight, body mass index, skinfold thicknesses and circumferences (r = 0.26 - r = 0.47). A significant correlation of intra-abdominal depth with systolic blood pressure (r = 0.17) and with high-density cholesterol (r = 0.20) was found. The prevalence of pre-hypertensive or hypertensive systolic blood pressure was 20.2 % and in diastolic blood pressure it was 6.2 %. In 52.9 % elevated total cholesterol values were found, and 22.9 % of the children had high low-density cholesterol levels. In 8.8 % high-density cholesterol was low.
Conclusions: Intra-abdominal depth as well as anthropometric parameters may be helpful in identifying children with adverse blood pressure and high-density-cholesterol levels. Cardiovascular risk factors can already be found in 6 - 9 year old children.||dc.description.abstract
