Objective: Antipsychotics are associated with weight gain and diabetes. The risk and rate of diabetes in children and adolescents treated with antipsychotics is unclear., Method: A longitudinal register linkage case-control study of diabetes in all psychiatric patients aged <18 years in Denmark was performed from January 1999 through the end of June 2010. Patients with and without antipsychotic exposure were compared regarding the occurrence of type 2 diabetes, defined as the prescription of oral antidiabetic medication. Regression analyses with type 2 diabetes as the dependent variable were conducted with sex, age, and diagnoses as covariates., Results: We compared the risk of diabetes in 48,299 psychiatrically ill youth. Of 7,253 youth exposed to antipsychotics, 52 (0.72%; 95% CI = 0.52% - 0.91%) developed type 2 diabetes. Of 41,046 youth without exposure to antipsychotics, 111 (0.27%; 95% CI = 0.22% - 0.32%) developed type 2 diabetes. In a 25,033 + 16,013 logistic regression analysis, type 2 diabetes development was associated with antipsychotic drug exposure (odds ratio [OR] = 1.60; 95% CI = 1.08 - 2.36, p < .05) female sex, (OR = 4.48; 95% CI = 2.90 - 6.91, p < 0.001) and older age at first psychiatric diagnosis (OR = 1.19; 95% CI = 1.12 - 1.27, p < 0.001), but not with psychiatric diagnosis. In a Cox-regression analysis, shorter time to type 2 diabetes onset was associated with female sex (Hazard Ratio (HR) = 4.83; 95% CI = 3.05-7.66, p = 0.001), and older age at first psychiatric diagnosis (HR = 1.19; 95% CI = 1.12-1.28, p = 0.001), while antipsychotic exposure (HR) = 1.41; 95% CI = 0.92-2.16, p = 0.11) trended towards increasing the rate of diabetes., Conclusion: Antipsychotic treatment, female sex, and older age at psychiatric diagnosis were associated with a significantly more frequent type 2 diabetes onset in children and adolescents. Strict indications for antipsychotic treatment and routine cardiometabolic monitoring are crucial., (Copyright © 2014 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc.

Objective: To explore changes in the diagnosed incidence of early onset schizophrenia (EOS) from 1971 to 2010., Method: Examination of incidence rates of schizophrenia in patients under 18 years of age, using a nationwide, population-based, mental health register., Results: The age-standardized incidence rate (IR) of EOS in the period 1971-2010 was 3.17 (95% CI: 3.16, 3.18) per 100 000 person years in the age group 0-18 years, and 9.10 (95% CI: 9.00, 9.21) in the age group 12-18 years. In the period 1971-1993, the age-standardized IR of EOS was 1.80 (95% CI: 1.79, 1.82) per 100 000 person years in the age group 0-18 years, and 5.02 (95% CI: 4.92, 5.11) in the age group 12-18 years. In the period 1994-2010, the age-standardized IR of EOS was 5.15 (95% CI: 5.10, 5.20) per 100 000 person years in the age group 0-18 years, and 15.73 (95% CI: 15.22, 16.22) in the age group 12-18 years. The IR was higher for males than females in the periods 1971-1993 and 1971-2010, but in the period 1994-2010 the IR was higher for females than males., Conclusion: In recent years, the diagnosed incidence of EOS has increased and the usual male excess has disappeared. The changes in IR could be a result of changes in the diagnostic system, increased awareness of early psychosis or a reflection of actual underlying incidence of the disorder., (© 2012 John Wiley & Sons A/S.)
