Young women more affected by alcohol use than men: Study

New York-  Female college students are more likely to depend on alcohol to improve mental well-being, say researchers, adding that the young women appear to be more affected by high alcohol use than men, which may lead to less interest in academics.

"Cognitive aptitudes of young women appear to be more affected than for men with high alcohol use," said study lead author Lina Begdache, Assistant Professor at Binghamton University in the US.

"These behaviours are regulated by the limbic system of the brain. However, the cognitive functions for high alcohol use among the young men and women were different," Begdache added.

For the findings, published in the journal Trends in Neuroscience and Education, researchers sought to compare neurobehaviours and academic effort among college students with low alcohol use with those of high alcohol consumption and build conceptual models that represent the integration of the different variables.

They sent an anonymous survey to assess college students' alcohol use and frequency along with questions on sleep, academic performance and attitude toward learning. They compared gender responses and found that both young men and women exhibit common behavioural responses to high alcohol use such as abuse of other substances and risk-taking.

The findings showed that young women reported generally less interest in the academic work and performance than young men. The latter reported more risky behaviours, such as being arrested, from excessive drinking.

The study also found that young women are more likely to depend on alcohol to improve mental well-being, which is also concerning, as they may self-medicate through drinking. In both genders, the researchers reported an increase in impulsive behaviours, which are under the control of the limbic system (the oldest part of the brain, evolutionary speaking).

Another reason for the difference seen is the differential metabolism of alcohol. Women metabolise alcohol at a slower rate, therefore, they are more likely to feel the effect of alcohol. Consequently, their brain is more likely to accumulate a toxic metabolite, acetaldehyde, which may be altering brain chemistry further to add to the differential behaviours identified in this study.

"Academic performance and risky behaviours among college students may be linked to their drinking habits, so more education and awareness should be shared with college students," said Begdache.

"These findings are also explained by the fact that women tend to have higher connectivity between cortices, while men have a large cortical volume in the areas on the limbic system that support impulsivity," Begdache added.
