Background: The purpose of this study was to provide health screening for low-income people and early diagnosis and treatment for health risk factors and diseases for the promotion of the health of vulnerable people. This study was also aimed toward the implementation of a comprehensive cancer health screening system to improve quality of life.
Methods: This study was conducted in 1,546 subjects aged >40 years who underwent free cancer screening between February and December 2017 in the Jeollanam-do region. In the first, we performed a survey HBsAg, Anti-HBs, 54 peoples with hepatitis B abnormalities were checked to secondary screening, HBeAg/Anti-HBe, HBV DNA.
Results: The overall HBsAb total seropositivity rate was 59.8% (924/1,546), and the HBsAb total seronegativity rate was 40.2% (622/1,546). The HBsAg total seropositivity rate was 3.8% (58/1,546) overall, 1.7% (26/1,546) in the men, and 2.1% (32/1,546) in the women. The HBeAg seropositivity rate was 11.1% (6/54) in the second hepatitis B screening.
Conclusion: We found that the positivity and negativity rates of HBsAb (Anti-HBs) were similar to those reported in other studies, but the positivity rate of HBeAg was slightly higher in the second hepatitis screening. In future surveys, factors must be analyzed, including an additional investigation of the related health risk factors to confirm the factors that affect diagnosis and initial evaluation results.
