Antipsychotics have already been linked to type II diabetes in adults. Now a new study shows a connection between these medications and the chronic medical condition in kids as well. Researchers report in the journal JAMA Psychiatry that children taking antipsychotics have three times the risk of developing type II diabetes, compared to children taking other psychotropic medications (drugs prescribed to treat mental disorders). The study authors were surprised by the magnitude of the results. But the findings make sense, given that the side effects of antipsychotics include weight gain and insulin resistance, said Wayne A. Ray, study co-author and researcher in the Department of Preventive Medicine at Vanderbilt University School of Medicine. However, the study shows an association, not a cause-effect relationship. It's not uncommon for an adult taking antipsychotic medications to gain 20 to 40 pounds in a relatively short period of time, Ray said. Similar weight gain effects have been observed in children, proportionate to their body sizes.

Antipsychotics are prescribed to some children with
attention and conduct disorders because these medications are potent tranquilizers, and can reduce the occurrence of some types of behavior problems such as aggressiveness, Ray said. But all of these mental conditions have other therapeutic options, and antipsychotics are often a secondary or off-label choice, the study said.

Researchers examined the medical records of patients between the ages of 6 and 24 who were enrolled in the Tennessee Medicaid program. The sample size was large: There were 28,858 participants who had recently started taking antipsychotic drugs, and 14,429 in the control group who had recently begun a different psychotropic medication. The
most common diagnoses in the study group were ADHD and other problems of conduct, Ray said. Other conditions for which antipsychotics were prescribed included depression and bipolar disorders.
Results
Study authors found a
three-fold increased risk of type II diabetes in the patients taking antipsychotics, compared to those who were taking other psychotropic drugs.
The risk was found particularly in children ages 6 to 17.. Researchers observed this association between antipsychotics and diabetes
within one year of follow-up. "We typically think of type II diabetes as a disease that takes a long time to develop, but what our finding implies is that even rather short-term use of these drugs in children and youth might not be safe with regard to diabetes," Ray said. The total amount of antipsychotics patients took during the study period affected their risk of developing type II diabetes as well, researchers found; the higher the cumulative dose, the higher the risk. And for up to a year after participants stopped using antipsychotics, the risk remained heightened.

This study did not examine patients who had type II diabetes and whether the condition could be reversed, but Ray said there could be diabetes cases among users of psychotropic drugs in which it becomes a lifetime chronic disease. "Before you’re going to expose a child to a medication that has many dangers –- not just the one we’ve uncovered, but many others –- you should think carefully about alternatives," Ray said. "My opinion is that only after you've tried those other things, should you then think about antipsychotics."
