Background Although hepatitis B seroprevalence has been studied extensively in California and New York, detailed information for other high-risk areas in the United States is lacking. To study current prevalence and risk for hepatitis B virus (HBV) infection in Hawaii, we analyzed cross-sectional data from Hawaii residents screened between July 2003 and April 2006. Methods We retrospectively reviewed the screening records of 3,989 participants recruited at health fairs and clinics. Prevalence and risk factors for HBV infection were estimated using univariate and multivariate logistic regression models. Results Total prevalence of hepatitis B surface antigen (HBsAg) was 3.6%. Gender, age, and ethnicity were independently associated with HBsAg seropositivity. In a multivariate logistic regression model, males were at increased risk for HBsAg compared with females (odds ratio [OR] = 1.53, 95% confidence interval [CI]: 1.09-2.16) and persons aged 70 years or older were less likely to test positive than those younger than 30 (OR = 0.25, 95% CI: 0.11-0.61). In addition, multivariate ORs of HBsAg seropositivity were 3.24 (95% CI: 1.04-10.09), 4.13 (95% CI: 1.66-10.29), and 7.47 (95% CI: 2.52-22.11) for Vietnamese, Chinese, and Pacific Islanders, respectively, compared with Whites. Conclusions This study furthers current knowledge of HBV epidemiology in areas with large populations of highrisk immigrants and demonstrates the relevance of screening programs for hepatitis B.
In this community-based sample of older adults, higher levels of WC are significantly associated with RAC independently of CVD risk factors. Adults who meet World Health Organization criteria for high WC may be at higher risk for complications of calcified atherosclerosis in the renal arteries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
