Abstract A37: Outcomes of a Randomized Community Trial to Increase Pap Testing among Pacific Islanders in Southern California

Abstract

Background: Pap tests comprise an essential cervical cancer prevention and detection method for women in the U.S. Unfortunately, the Pap test remains significantly underutilized among many ethnic/racial groups, particularly Pacific Islanders (PIs) who have low rates of Pap testing and high rates of cervical cancer incidence and mortality. Methods: A randomized community trial tested the efficacy of a social support-informed culturally developed intervention on increasing Pap testing among Chamorro, Samoan and Tongan women in Southern California. Using community-based participatory research (CBPR), Pacific Islander women and their husbands/partners were recruited from social organizations (churches and clans) that had been randomly assigned to receive the intervention or control education. Three waves (pretest, posttest and 6-month follow-up) of data collection included demographics, cervical cancer beliefs, social support between women and their husbands/partners, and Pap test attitudes and behaviors. Results: CBPR recruitment resulted in a total of 81 social organizations recruited that included n=575 Pacific Islander women and n=461 husbands/partners. Significant differences between groups at baseline included acculturation and health insurance coverage. Six month follow-up found that all women from baseline significantly increased knowledge and decreased fatalistic attitudes towards Pap testing. Women who were not adherent to Pap test guidelines in the intervention group had significantly higher rates of Pap testing compared to controls at six month follow-up. No differences were found in either women's perceived social support nor men's provision of social support for Pap testing. Conclusion: CBPR-informed behavioral interventions can increase cervical cancer screening in Pacific Islander women. Although social support did not mediate the relationship between women's knowledge and behavior, it did inform the development of a culturally tailored intervention for Chamorro, Samoan and Tongan women. Future studies can build upon these results by addressing other early detection (e.g., mammograms, colorectal exams, etc) and prevention (e.g., HPV vaccination) in these and other disparity populations.

Awareness of and Support for HPV Vaccination Among Pacific Islander Women in Southern California

“…Data were drawn from a longitudinal community randomized social support study to increase Pap testing among Chamorro, Samoan, and Tongan women in southern California. The study was led by a CBPR partnership involving 1 academic institution, 4 PI-serving community-based organizations, and a Community Advisory Board (CAB) that guided all aspects of the study including the original research questions, designing and translating all instruments, and engaging community members as partners and participants [10]. Participants were members of PI faith-based organizations or social clans, 21-65 years of age, and in a long-term partnership or marriage for at least 5 years (since the intervention targeted women and their husbands/partners).…”

“…All participants received $10 for completing the pre-test survey and $15 for completing the 6-month follow-up survey, either in person (by paper and pencil) or online. See a previous publication for more details on the data collection measures [10].…”
