BackgroundWeight gain is a major side effect of antidepressant (AD) drugs. We assessed whether early weight gain is a predictor for long term weight gain in depressed patients treated with antidepressants.MethodsIn the six month prospective METADAP cohort, 260 non-overweight patients with a major depressive disorder (MDD), who have recently experienced a Major Depressive Episode (MDE) were assessed for early weight gain (>3%,>5%, and >7%) after one month of treatment, and for long term weight gain (>15% and >20%) after three and six months of treatment. ROC analysis was used to determine the predictive power of early weight gain.Results12.4% (21/170) of patients became overweight after three months of treatment and 21.1% (26/123) were overweight after six months. Compared to non-early weight gainers, patients with early weight gain (>3%, >5% and >7%) were 11.3 (OR = 11.3, 95%CI: 4.6-27.6)], 9.9 (OR = 9.9, 95%CI: 3.6-26.9)] and 17.8 (OR = 17.8, 95%CI: 6.4-49.4)] times, respectively, more at risk of late weight gain (>15%). ROC analysis showed that early weight gain (>3%) after one month of treatment, was the best predictor of long term weight gain (≥15%) after three months [Area Under the Curve (AUC )= 87%] and six months of treatment (AUC = 88%) PERSPECTIVES: Given that our baseline sample consisted of strictly non-overweight patients, the 3% threshold for weight gain after one month should be used as an indicator to initiate early weight monitoring in depressed patients treated with antidepressants. High attrition rate remains a limitation in this cohort and other cohorts in psychiatric settings.DisclosuresBruno Falissard consults for and received lecture fees from for E.
