Abstract

Background and purpose: Asian-Americans suffer from significant liver cancer disparity caused by chronic hepatitis B virus (HBV) infection. Understanding psychosocial predictors of HBV screening is critical to designing effective interventions.

Methods: Chinese-, Korean-, and Vietnamese-Americans in the Baltimore-Washington metropolitan region (N=877) were recruited from community-based organizations. Applying the Social Cognitive Theory (SCT), three main theoretical constructs (knowledge, outcome expectancy, and self-efficacy) were tested. Descriptive analyses using Chi-square and ANOVA and multivariate logistic regression models were conducted.

Results: About 47% of participants reported ever having screening for HBV. Vietnamese-Americans had the lowest HBV screening rate (39%), followed by Korean-Americans (46%) and Chinese-Americans (55%). Multiple logistic regression analyses showed significant effects of HBV-related knowledge on screening in all three groups, whereas self-efficacy had significant effects in the Chinese and Korean subgroups, but not Vietnamese. HBV outcome expectancy had no effect on the screening outcome in any of the groups. Additionally, consistent in all three groups, those who had lived in the United States longer were less likely to have screening.

Conclusion: HBV screening rates in Asian Americans remain low; targeted interventions need to consider the differences across ethnic subgroups and address the psychosocial risk factors.

基于社会认知理论的亚裔美国人乙型肝炎病毒筛查行为评估
背景与目的:慢性乙型肝炎病毒(HBV)感染导致的亚裔美国人患肝癌的比例存在显著差异。了解HBV筛查的社会心理预测因素对于设计有效的干预措施至关重要。方法:从社区组织中招募巴尔的摩-华盛顿大都市区的华裔、韩裔和越南裔美国人(N=877)。运用社会认知理论(SCT)对三个主要理论构念(知识、结果期望和自我效能)进行了测试。描述性分析采用卡方、方差分析和多元logistic回归模型。结果:约47%的参与者报告曾接受过HBV筛查。越南裔美国人的HBV筛查率最低(39%),其次是韩裔美国人(46%)和华裔美国人(55%)。多元逻辑回归分析显示,在所有三组中,hbv相关知识对筛查有显著影响,而自我效能感在中国和韩国亚组中有显著影响,但在越南没有显著影响。在任何一组中,HBV预后预期对筛查结果都没有影响。此外,在所有三组中一致的是,那些在美国生活时间较长的人不太可能进行筛查。结论:亚裔美国人的HBV筛查率仍然很低;有针对性的干预措施需要考虑不同族裔群体之间的差异,并解决社会心理风险因素。
