Abstract:

Importance: Antidepressants are one of the most commonly prescribed classes of psychotropic medications among US youths. For adults, there is emerging evidence on the increased risk of type 2 diabetes in association with antidepressant use. However, little is known about the antidepressant treatment-emergent risk of type 2 diabetes among youths.

Objective: To assess the association between antidepressant use and the risk of incident type 2 diabetes in youths by antidepressant subclass and according to duration of use, cumulative dose, and average daily dose.

Design, Setting, and Participants: A retrospective cohort study was conducted using Medicaid claims data from 4 geographically diverse, large states of youths 5 to 20 years of age who initiated antidepressant treatment from January 1, 2005, to December 31, 2009.

Exposures: Antidepressant use (selective serotonin reuptake inhibitors [SSRIs] or serotonin-norepinephrine reuptake inhibitors [SNRIs], tricyclic or other cyclic antidepressants, and other antidepressants) was assessed using the following 4 time-varying measures: current or former use, duration of use, cumulative dose, and average daily dose.

Main Outcomes and Measures: Incident type 2 diabetes was assessed using discrete-time failure models, adjusting for disease risk score estimated using more than 125 baseline and time-dependent covariates.

Results: In this cohort of 119 608 youths aged 5 to 20 years who initiated antidepressant treatment (59 087 female youths and 60 521 male youths; 54.7% between 5 and 14 years of age) with a mean follow-up of 22.8 months, 79 285 [66.3%] had SSRI or SNRI exposure. The risk of type 2 diabetes was significantly greater during current use than former use of SSRIs or SNRIs (absolute risk, 1.29 per 10 000 person-months vs 0.64 per 10 000 person-months; adjusted relative risk [RR], 1.88; 95% CI, 1.34-2.64) and tricyclic or other cyclic antidepressants (absolute risk, 0.89 per 10 000 person-months vs 0.48 per 10 000person-months; RR, 2.15; 95% CI, 1.06-4.36), but not of other antidepressants (absolute risk, 1.15 per 10 000 person-months vs 1.12 per 10 000 person-months; RR, 0.99; 95% CI, 0.66-1.50). Furthermore, for youths currently using SSRIs or SNRIs, the risk of type 2 diabetes increased with the duration of use (RR, 2.66; 95% CI, 1.45-4.88 for>210 days and RR, 2.56; 95% CI, 1.29-5.08 for 151-210 days compared with 1-90 days) and with the cumulative dose (RR, 2.44; 95% CI, 1.35-4.43 for>4500 mg and RR, 2.17; 95% CI, 1.07-4.40 for 3001-4500 mg compared with 1-1500 mg in fluoxetine hydrochloride dose equivalents). By contrast, neither the duration nor the cumulative dose of other antidepressants was associated with an increased risk of type 2 diabetes. The risk of type 2 diabetes increased significantly with the average daily dose among youths with more than 150 days of SSRI or SNRI use (RR, 2.39; 95% CI, 1.04-5.52 for>15.0 vs≤15.0 mg/d) but not among youths with 1 to 150 days of SSRI or SNRI use.

Conclusions and Relevance: In a large cohort of youths insured by Medicaid, the use of SSRIs or SNRIs-the most commonly used antidepressant subclass-was associated with an increased risk of type 2 diabetes that intensified with increasing duration of use, cumulative dose, and average daily dose.
