Prevalence, Awareness, and Treatment of Hepatitis C Virus Infection in South Korea: Evidence from the Korea National Health and Nutrition Examination Survey.

ABSTRACT: Background/Aims:This study aimed to investigate the epidemiology of hepatitis C virus (HCV) infection in the Korean general population and the awareness and treatment status of HCV infection among anti-HCV-positive persons. Methods:We used data from the Korea National Health and Nutrition Examination Survey (KNHNES) collected between 2012 and 2016. All the participants aged ?10 years in the KNHNES were tested for the anti-HCV antibody. Anti-HCV-positive persons were tested for HCV RNA and assessed for their awareness and treatment experience regarding HCV infection. Results:The prevalence of anti-HCV was 0.66% (95% confidence interval, 0.56% to 0.78%) among Koreans aged ?10 years, representing an estimated 278,819 anti-HCV-positive persons, and 0.71% (95% confidence interval, 0.60% to 0.84%) among Koreans aged ?20 years. The prevalence of anti-HCV increased with age and had significant geographic variation. The positive rate of HCV RNA in anti-HCV-positive persons was 33.5% and increased with age. The rate of HCV infection awareness was 15.2% (35/250) among anti- HCV-positive persons and 30.5% (18/59) among HCV RNApositive persons. Among the participants, 13.5% of HCV RNA-positive persons had been treated for HCV infection. Conclusions:The prevalence of anti-HCV among Koreans aged ?20 years was 0.71%; one-third of anti-HCV-positive persons tested HCV RNA-positive. The awareness and treatment rates of HCV infection were low among HCV-infected persons. Therefore, active measures should be taken to diagnose and treat persons unaware of HCV infection.

Project description:BackgroundFamily history (FH) is one of important risk factors for cardiovascular disease (CVD). However, little is known about its impact on dyslipidemia prevalence and management status. Thus, we aimed to investigate the impact of FH of CVD on dyslipidemia prevalence, awareness, treatment, control, and healthy behaviors in Korean adults.MethodsWe conducted a cross-sectional study using representative data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2014-2018. A total of 22,024 participants aged ≥ 19 years without histories of CVDs were classified into two groups according to the presence of FH of CVD (with FH, n = 3,778; without FH, n = 18,246). FH of CVD was defined as having a first-degree relative with ischemic heart disease or stroke. Multivariate logistic regression analyses were performed to evaluate the association between FH of CVD and dyslipidemia prevalence, awareness, treatment, control, and healthy behaviors (weight control, non-smoking, non-risky drinking, sufficient physical activity, and undergoing health screening).ResultsFH of CVD was significantly associated with a higher dyslipidemia prevalence (adjusted odds ratio [aOR] 1.34, 95% confidence interval [CI] 1.18-1.51), better awareness (aOR 1.54, 95%CI 1.19-2.00), and treatment rates (aOR 1.34, 95%CI 1.12-1.60), but not control. Having an FH of CVD was not predictive of any healthy behaviors in dyslipidemia patients. For non-dyslipidemia patients, FH of CVD even showed significant association with smoking (aOR 1.18, 95%CI 1.02-1.36), and risky drinking (aOR 1.20, 95%CI 1.03-1.40) while it was predictive of receiving health screening (aOR 1.14, 95% CI 1.02-1.27).ConclusionsHaving an FH of CVD might positively trigger dyslipidemia patients to start pharmacological intervention, but not non-pharmacological interventions. Therefore, physicians should make more efforts to educate and promote the importance of non-pharmacological behavioral modification in dyslipidemia patients with an FH of CVD.
