Background:
Most individuals with alcohol use disorder (AUD) do not seek treatment. Stigma and the desire to self-manage the problem are likely explanations. Exercise is an emerging treatment option but studies in non-treatment seeking individuals are lacking. We compared the effects of aerobic exercise, yoga, and treatment as usual (phone-based support) on alcohol consumption in non-treatment seeking adults with AUD.
Methods:
Three-group parallel, single blind, randomized controlled trial. 140 physically inactive adults aged 18-75 diagnosed with AUD were included in this community-based trial. Participants were randomized to either aerobic exercise (n = 49), yoga (n = 46) or treatment as usual (n = 45) for 12-weeks. The primary study outcome was weekly alcohol consumption at week 13 (Timeline Follow-back).
Results:
A significant decrease in weekly alcohol consumption was seen in all three groups: aerobic exercise (mean ∆ = - 5.0, 95% C = - 10.3, - 3.5), yoga group (mean ∆ = - 6.9, 95% CI = - 10.3, - 3.5) and TAU (mean ∆ = - 6.6, 95% CI = - 8.8, - 4.4). The between group changes were not statistically significant at follow-up. Per-protocol analyzes showed that the mean number of drinks per week reduced more in both TAU (mean ∆ = - 7.1, 95% CI = - 10.6, - 3.7) and yoga (mean ∆ = - 8.7, 95% CI = - 13.2, - 4.1) compared to aerobic exercise (mean ∆ = - 1.7, 95% CI = - 4.4, 1. 0), [F(2, 55) = 4.9, p = 0.011].
Conclusions:
Participation in a 12-week stand-alone exercise program was associated with clinically meaningful reductions in alcohol consumption comparable to usual care (phone counseling) by an alcohol treatment specialist.
