Association Between Pharmacological Treatment of Attention-Deficit/Hyperactivity Disorder and Long-term Unemployment Among Working-Age Individuals in Sweden

• Importance: Adults with attention-deficit/hyperactivity disorder (ADHD) are at greater risk for unemployment. Pharmacological treatment is effective in reducing the core symptoms of ADHD, but whether it helps to reduce the unemployment rate among adult patients remains unclear.Objective: To investigate the association between use of ADHD medication and long-term unemployment in working-age adults with ADHD.Design, Setting, and Participants: Data for this population-based cohort study were extracted from Swedish national registers. Among 25 358 individuals with ADHD born from 1958 to 1978, 12 875 middle-aged adults among the workforce were included. The longitudinal cohort was followed up from January 1, 2008, to December 31, 2013. Data were analyzed from March 1, 2020, through May 31, 2021.Exposures: Use of medication for ADHD during the previous 2 years was the main exposure, as both categorical and continuous variables.Main Outcomes and Measures: Yearly accumulated unemployed days were derived from the Public Employment Service, and long-term unemployment was defined as 90 or more days of unemployment per year. Overall and sex-specific relative risks (RRs) with 95% CIs were estimated using generalized estimating equations.Results: Among 12 875 individuals with ADHD (5343 women [41.50%] and 7532 men [58.50%]; mean [SD] age, 37.9 [5.6] years), the use of ADHD medications during the previous 2 years was associated with a 10% lower risk of long-term unemployment in the following year (adjusted RR, 0.90 [95% CI, 0.87-0.95]). An association between use of ADHD medications and long-term unemployment was found among women (RR, 0.82 [95% CI, 0.76-0.89]) but not men (RR, 0.96 [95% CI, 0.91-1.01]). Longer treatment duration was associated with a lower risk of subsequent long-term unemployment among women (RR for use of 1-6 months, 0.86 [95% CI, 0.78-0.95]; RR for use of 18-24 months, 0.72 [95% CI, 0.58-0.90]; P < .001 for trend). Within-individual comparisons showed that the long-term unemployment rate was lower during periods of ADHD medication treatment compared with nontreatment periods (RR, 0.89; 95% CI, 0.85-0.94).Conclusions and Relevance: The findings of this cohort study suggest that the use of ADHD medication is associated with a lower risk of subsequent long-term unemployment for middle-aged women. These findings should be considered together with the existing knowledge of risks and benefits of ADHD medication when developing treatment plans for working-age adults.
