title: The usefulness of measuring body fat deposition for detecting obesity and atherogenesity in Japanese school children.
abstract: Body fat deposition was measured in overweight and non-overweight children using a bioelectrical impedance method, and its relationship with serum lipids and apolipoproteins was investigated in 90 overweight children (over 120% of their ideal weight) and 241 non-overweight children aged 10-15 years in Niigata Prefecture. The results were as follows. Overweight boys had significantly higher levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), atherogenic index (AI), RLP-cholesterol (RLP-C), apoA1, apoA2, apoB, apoC2, apoC3, apoE and the ratio of apoB to apoA1 than non-overweight boys. Overweight girls had significantly higher levels of TC, LDL-C, AI, remnant-like lopoprotein cholesterol (RLP-C), apoA2, apoB, apoC2, apoC3, apoE and the ratio of apoB to apoA1 than non-overweight girls. It has been reported that of all children studied 2.1% had higher levels of RLP-C than its upper limit known for adults (12 mg/dL). Of the overweight children in the present study, 4.4% had a high level of RLP-C whereas only 1.2% of non-overweight children had a high RLP-C level. No difference in the lipoprotein levels was found between overweight and non-overweight children. In both boys and girls, relative weight, body fat, skinfold thickness and body mass index (BMI) were correlated with the lipoprotein levels. Non-overweight boys whose body fat was over 20% had significantly higher levels of TC, LDL-C, apoA2, apoB, apoC2, apoE and apoB/A1 than those whose body fat was less than 20%. It was concluded that the measurement of body fat deposition, together with relative weight, was useful for detecting obesity and atherogenesity in Japanese school children.
