Study on blood biochemical variables of obese children screened by new BMI and weight-for-height criterion / 中华流行病学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the abnormal state of liver function and plasma lipid levels of obese schoolchildren who were screened by weight-for-height criterion and new body mass index criterion respectively.</p><p><b>METHODS</b>280 obese children were screened by weight-for-height criterion and 125 obese children were screened by body mass index criterion in a routine school check-up program. All of the latter subjects was included in the former one. One obese child and 1 non-obese child were matched for gender and age. 14 items related to liver functions and plasma lipids were measured.</p><p><b>RESULTS</b>Of the abnormal items,7 items in 125 obese children screened by new BMI criterion and 5 items in 155 "obese children" excluded by BMI criterion, were significantly higher than those children among controlled group. The abnormal rates were 10.4%-22.9% in the former and 3.2%-13.0% in the latter.</p><p><b>CONCLUSIONS</b>The new BMI criterion seemed to be more stringent than weight-for-height. Less than a half of the obese children screened by weight-for-height were taken on obese children by new BMI criterion. The overweight children who were screened by BMI criterion also had abnormal liver functions and plasma lipids.</p>
