Sex/Gender Differences in Addictive Disorders

Addictive disorders are characterized by a decrease in functionality, leading to significant disruptions in daily life, due to the excessive use of certain substances or behaviors that initially induce pleasure, but ultimately result in a loss of control. There are sex/gender differences in the pathophysiology, clinical symptoms, and treatment of addictive disorders, since these disorders are caused by an interplay of biological and socio- environmental factors. It is crucial to take these differences into account in both research and clinical practice. From a neurobiological perspective, women may exhibit a faster progression toward addictive disorders, due to their reward circuit’s heightened sensitivity when exposed to addictive substances. Additionally, they may be more prone to relapse because of their increased sensitivity to stress and withdrawal symptoms. The prevalence of alcohol and drug use disorders is higher in men, but in Korea that belongs to Asia, alcohol use disorder is now more common among women in their 30s than among men of the same age group, reflecting an increase in prevalence among women over the last 10 years. Gaming disorders are more prevalent among men, while social media overuse is higher among women, who have a stronger emotional and interpersonal orientation than men. In treating addictive disorders, it is necessary to implement specialized programs for women. However, these programs should not perpetuate bias, while given the rising number of women with addictive disorders, we need strategies to improve their access to these programs.
