HealthDay News — Young adults with attention-deficit/hyperactivity disorder (ADHD) have an increased prevalence of substance use disorders (SUDs), including alcohol use disorder, according to a study published online in Alcohol and Alcoholism.

Esme Fuller-Thomson, PhD, from the University of Toronto, and colleagues conducted a secondary analysis of the Canadian Community Health Survey-Mental Health, which included 6872 respondents aged 20 to 39 years, of whom 270 had ADHD. Data on SUDs were derived from lifetime algorithms for alcohol, cannabis, and other substance abuse or dependence.

The researchers found that 36% of young adults with ADHD had a lifetime alcohol use disorder compared with 19% of those without ADHD. Those with ADHD had increased odds of developing alcohol use disorders, cannabis use disorders, other drug use disorders, and any SUD after adjustment for all control variables (odds ratios, 1.38, 1.46, 2.07, and 1.69, respectively). The largest attenuation of the ADHD-SUD relationship was seen when controlling for a history of depression and anxiety, followed by childhood adversities and socioeconomic status.

“These results emphasize the importance of addressing depression and anxiety when providing care to those with co-occurring ADHD and SUD,” Fuller-Thomson said in a statement. “Individuals with untreated depression and anxiety may self-medicate to manage the symptoms of an untreated psychiatric disorder, which can result in greater substance use.”
