Researchers at Henry Ford Well being, collaborating with WeightWatchers Worldwide, report that greater than 40% of people utilizing in style weight reduction drugs whereas taking part in a WeightWatchers clinic decreased their alcohol use.
Earlier associations have been famous between particular medicine and a decrease incidence of alcohol use dysfunction. Well being-conscious behavioral modifications in weight administration packages are additionally linked to decreased alcohol consumption. Inspecting alcohol use amongst people utilizing numerous drugs for weight reduction might provide insights into behavioral versus medicine results on alcohol discount.
In a examine, “Alcohol Use and Antiobesity Medication Treatment,” revealed in JAMA Community Open, researchers analyzed knowledge from members within the WeightWatchers telehealth weight administration program between January 2022 and November 2023.
Members had a imply age of 43.17 years and a imply physique mass index (BMI) of 35.97; 86.0% had been feminine. Most members (86.2%) had been prescribed a second-generation glucagon-like peptide-1 receptor agonist (GLP-1 RA). Roughly half (53.3%) reported alcohol use at baseline.
Drugs included metformin, bupropion mixed with naltrexone (Contrave), liraglutide (Saxenda), dulaglutide (Trulicity), tirzepatide (Zepbound), and semaglutide (Ozempic, Rybelsus). A number of the medicine used within the examine usually are not FDA-approved for weight reduction, and others weren’t accepted in the course of the examine timeframe.
Among the many 7,491 members reporting alcohol use at baseline, 52.4% reported no change, 45.3% decreased their consumption, and a pair of.3% reported a rise after becoming a member of the WeightWatchers telehealth weight administration program and initiating what the authors confer with as anti-obesity medicine (AOM). Members with increased weight problems ranges and better baseline alcohol use had been extra prone to cut back their alcohol consumption.
People receiving bupropion and naltrexone had the best chance of reducing alcohol use in comparison with these taking different medicine. Naltrexone is FDA-approved for treating alcohol dependence on account of its capability to cut back cravings and diminish rewarding results.
Bupropion has identified dangers when used with alcohol, with elevated seizure danger and damaging behavioral results, and sufferers receiving the mixed model would have been suggested by their doctor or pharmacist of the interplay warnings.
After statistically adjusting for weight reduction, the importance of bupropion and naltrexone’s impact disappeared, suggesting the discount could also be mediated by weight reduction somewhat than the medicine itself. This can be a exceptional discovering contemplating naltrexone’s identified pharmacological results in different examine settings.
If AOMs cut back alcohol use partly by selling weight reduction, adjusting for weight reduction might obscure this impact. This might decrease the obvious function of AOMs in alcohol consumption discount.
As an example, if GLP-1 RAs cut back the rewarding results of each meals and alcohol by way of related neural mechanisms, weight reduction isn’t a confounder however a mediator of alcohol use discount. On this case, adjusting for weight reduction would possibly downplay the contribution of AOMs to alcohol use modifications.
Members utilizing metformin reported the least lower in alcohol use, doubtlessly attributed to engagement within the weight administration program and related behavioral methods encouraging decreased alcohol consumption, as this is able to maintain for all members as they had been all enrolled in the identical program.
Problematic elements of the examine design
A number of limitations have an effect on the interpretation of the examine’s findings. The absence of a management group taking part within the weight administration program with out anti-obesity drugs makes it troublesome to isolate the results of medicines from behavioral interventions. Inclusion of such a bunch might have clarified whether or not behavioral modifications alone affect alcohol discount.
Statistical changes for weight reduction could obscure the direct results of medicines on alcohol consumption. If anti-obesity drugs cut back alcohol use partly by selling weight reduction, adjusting for weight reduction would possibly decrease the obvious function of the drugs.
Potential conflicts of curiosity exist, as a number of authors are workers of WeightWatchers Worldwide, which gives the burden administration program and sells a medicine seen favorably within the examine. This connection might introduce bias in reporting outcomes favorably for the corporate’s packages and merchandise.
Additional analysis is required to disentangle the results of medicines from behavioral interventions in influencing alcohol use.
