Alcohol use disorder (AUD) is a prominent public health issue. Heterogeneity among the patients with AUD makes its management even more challenging. Sex is an important biological factor contributing to the variations in the development and maintenance of AUD. Sex-related variations are also reported in disorders comorbid with AUD and in AUD-related outcomes, such as relapse and drop-out from alcohol treatment and negative life consequences, including suicidal behavior.
This doctoral thesis aimed to explore the sex-specific factors associated with neurobiological mechanisms, comorbidity, treatment adherence, and suicidal behavior in AUD patients.
Through an observational study conducted on AUD patients receiving rehabilitative services at three different residential in Norway, we obtained information on patients’ background, alcohol use, and mental health. In addition, the patients were assessed for alcohol use-related biomarkers.
We found that factors associated with the level of prolactin, a marker reflecting the neurobiological mechanism involved in AUD, were sex specific. Alcohol use trait-related factors, including age at alcohol debut, level of response to early alcohol use, and history of a parental drinking problem, were associated with the level of prolactin in the female AUD patients but not among males.
Similarly, antisocial personality disorder, which is a common comorbidity in AUD, was detected only among males, and relapse or drop-out in these patients were related to severe traumatic experiences and a higher biological drive to drinking.
In addition, although mental health-related factors were related to suicide attempts among both male and female AUD patients with a seemingly higher effect among the females, alcohol use-related factors were related to suicide attempts only among males.
These findings underline the need to consider sex differences while planning preventive, curative, and rehabilitative programs for AUD management.
