Ghrelin and leptin response to oral glucose challenge among antipsychotic drug-treated children.

We investigated ghrelin, leptin, glucose, and insulin response to an oral glucose tolerance test among children receiving antipsychotics. Hormone concentrations were assayed at fasting, 30, 60, and 120 minutes. The sample was composed of 9 obese (defined as at or above the 95th percentile for age) and 10 overweight/normal children (defined as less than the 95th percentile in weight) based on National Institutes of Health criteria.
