Glycosylated hemoglobin as a screening test for hyperglycemia in antipsychotic-treated patients: a follow-up study.

Purpose: To assess the point prevalence of undetected prediabetes (preDM) and diabetes mellitus (DM) in patients treated with antipsychotics and to compare metabolic parameters between patients with normoglycemia (NG), preDM, and DM. Furthermore, conversion rates for preDM and DM were determined in a 1-year follow-up.

Patients And Methods: In a naturalistic cohort of 169 patients, fasting glucose (FG) and hemoglobin A1c (HbA1c) criteria were applied at baseline and at follow-up after 1 year.
