Stress, by Itself, Can Lead to Excessive Drinking in Women but Not Men

Participants consumed alcoholic beverages in a simulated bar while experiencing stressful and non-stressful situations. Stress led women, but not men, to drink more than intended, a finding that demonstrates the importance of studying sex differences in alcohol consumption. The study was published in Psychology of Addictive Behaviors.
"Some people can intend to have one or two alcoholic beverages and stop drinking, but other people just keep going. This impaired control over drinking is one of the earliest indicators of alcohol use disorders, and we know stress contributes to both impaired control over drinking and dysregulated drinking. The role of stress in impaired control over drinking is understudied, especially in women," said Julie Patock-Peckham, assistant research professor at ASU and lead author on the study.
The study took place in a research laboratory designed to simulate a bar, complete with a bartender, bar stools and lively conversations. The participants included 105 women and 105 men. They were randomized into different groups, with some either experiencing a stressful situation and others a non-stressful situation. Next, half the participants received an alcoholic drink that was equivalent to three cocktails, and the other half received three non-alcoholic drinks. After that, all participants had unrestricted access to alcoholic drinks from the bar for 90 minutes.
[...] The experimental set-up let the research team determine whether stress, the initial drink or the combination of the two caused how much alcohol the participants consumed. The team measured alcohol consumption in total number of drinks consumed and by using breath blood alcohol content (BAC).
