ABSTRACT
INTRODUCTION AND OBJECTIVES:
Hepatitis B virus (HBV) infection can lead to cirrhosis, hepatocellular carcinoma, and death if untreated. In Mexico, HBV vaccination for all children and adolescents was implemented in 1999. In 2000 the estimated HBV was 0.21% in the population aged 20 years and older. We estimated the national prevalence for hepatitis B surface antigen (HBsAg) and its association with sociodemographic characteristics, including sexual behavior information for those aged 20 to 49 years. MATERIALS ANDMETHODS:
From the 2018 National Health and Nutrition Survey, blood samples were collected from a subsample of 2,280 adults to determine HBsAg. We estimated the national prevalence for HBsAg and evaluated its association with sociodemographic characteristics, adding sexual behavior information for those aged 20 to 49 years. We performed a multiple logistic regression to estimate the association of HBsAg and relevant variables.RESULTS:
The 2018 estimated prevalence of HBsAg in the Mexican adult population was 0.51% (95%CI 0.19, 2.33), which represents 411,000 cases. This prevalence was higher than previously estimated and it was higher in women than in men (0.54% versus 0.46%, respectively). We did not find an association between HBsAg and sociodemographic characteristics or sexual behaviors.CONCLUSIONS:
Vaccination and screening strategies towards the elimination of viral hepatitis should be reinforced to further reduce the prevalence over the next years.Palabras clave
