In the United States (US), rates of cervical cancer screening among Asian American women (notably Korean American women) lag far behind other populations. Thus, guided by the Health Belief Model, we developed a multi-component intervention to enhance Korean American women's knowledge and beliefs about screening and to increase screening uptake. The intervention group (N=341) received a culturally-relevant cancer education program and navigation services. The control group (N=335) received a similar program on cervical cancer risk and screening, along with information about free/low-cost screening sites. Women's knowledge and beliefs were measured at baseline and post-program, and screening behavior was assessed at 12-months post-program. It was hypothesized that the intervention would lead to positive changes in health beliefs and knowledge about cervical cancer and screening, which were then evaluated as potential mediators of the intervention on screening behavior. From pre- to post-program, the intervention group reported significantly greater increases in knowledge (<0.01) and perceived risk (=0.02) and significantly greater decreases in perceived barriers (<0.001) compared to the control group. However, changes in knowledge and health beliefs did not mediate intervention effects on screening behavior. Use of navigation services was associated with greater odds of obtaining screening (OR=3.15, 95% CI=2.28-4.01, <0.001) and attenuated the significant effect of group assignment (intervention vs. control) on screening behavior to non-significance. In conclusion, although our intervention program was effective in improving women's knowledge and beliefs about screening, delivery of navigation services was the critical component in increasing cervical cancer screening rates in this underserved population.
在美国,亚裔美国女性(尤其是韩裔美国女性)的宫颈癌筛查率远远落后于其他人群。因此,在健康信念模型的指导下,我们开发了一种多成分干预措施,以增强韩裔美国女性对筛查的知识和信念,并提高筛查接受率。干预组(N = 341)接受了与文化相关的癌症教育项目和导航服务。对照组(N = 335)接受了一个关于宫颈癌风险和筛查的类似项目,以及有关免费/低成本筛查地点的信息。在基线和项目结束后测量女性的知识和信念,并在项目结束后12个月评估筛查行为。假设该干预将导致对宫颈癌和筛查的健康信念和知识产生积极变化,然后将这些变化评估为干预对筛查行为的潜在中介因素。从项目前到项目后,与对照组相比,干预组报告的知识(<0.01)、感知风险(=0.02)显著增加,感知障碍显著降低(<0.001)。然而,知识和健康信念的变化并未介导干预对筛查行为的影响。使用导航服务与进行筛查的几率更高相关(OR = 3.15,95% CI = 2.28 - 4.01,<0.001),并使组分配(干预组与对照组)对筛查行为的显著影响减弱至不显著。总之,尽管我们的干预项目在改善女性对筛查的知识和信念方面是有效的,但导航服务的提供是提高这一服务不足人群宫颈癌筛查率的关键组成部分。
