Abstract

Background: Chronic hepatitis B virus (HBV) infection may evolve into cirrhosis and hepatocellular carcinoma, and this progression may be accelerated by specific risk factors, including overweight and obesity. Although evidence for a protective effect of cannabis use on elevated body weight has been found for other populations, no data are available for HBV-infected patients.

Aims: We aimed to identify risk factors (including cannabis use) for overweight and obesity in patients with HBV chronic infection.

Methods: Using baseline data from the French ANRS CO22 Hepather cohort, we performed two separate analyses, one using “central obesity” (based on waist circumference) and the other “overweight” and “obesity” (based on body mass index) as outcomes. Logistic and multinomial regressions were used to model central obesity and overweight/obesity, respectively.

Results: Among the 3706 patients in the study population, 50.8% had central obesity, 34.7% overweight, and 14.4% obesity. After multivariable adjustment, current cannabis use was associated with a 59% lower risk of central obesity compared with no lifetime use (adjusted odds ratio [95% CI]: 0.41 [0.24 to 0.70]). It was also associated with a 54% and 84% lower risk of overweight (adjusted relative risk ratio [95% CI]: 0.46 [0.27 to 0.76]) and obesity (0.16 [0.04 to 0.67]), respectively.

Conclusions: Cannabis use was associated with lower risks of overweight and obesity in patients with HBV chronic infection. Future studies should test whether these potential benefits of cannabis and cannabinoid use translate into reduced liver disease progression in this high-risk population.
