A study of the adverse effects of 4 second-generation antipsychotics in children and adolescents documented substantial weight gain during 11 weeks of treatment with each agent, with the increased abdominal fat that has been associated with development of metabolic syndrome in adults. Metabolic abnormalities emerged with 3 of the 4 agents, differing in type and severity with the agent and, in some cases, with the dose.
In this analysis from the Second-Generation Antipsychotic Treatment Indications, Effectiveness and Tolerability in Youth (SATIETY) study, 10% to 36% of 272 patients between 4 and 19 years of age (mean, 13.9 years) who had not previously received antipsychotic medication became overweight or obese. There was minimal weight change in a comparison group of patients who had refused the agent, or who discontinued it within 4 weeks.1
Christoph Correll, MD, Zucker Hillside Hospital, Glen Oaks, NY, and colleagues conducted this observational cohort study as the largest to date of adverse experiences with second-generation antipsychotics in antipsychotic treatment–naive children. The researchers noted that there has been increasing use of these agents in younger patients for psychotic and bipolar disorders as well as nonpsychotic disorders, despite little available age-specific data on adverse reactions.
