Abstract
Data from the National Cancer Database indicates prostate cancer (CPa) prevalence in the Pacific Islander (PI) community to be nearly 1.6 times higher than the national standard. Recent data suggests that prostate cancer rates seen in United States PI men are comparable to that of African American men, the community with the longstanding recognition as having the highest rates of the disease in the US. PIs are defined as those originating from or being indigenous to the islands of Polynesia, Melanesia, and Micronesia including the US governed Hawaiian islands, Guam, Northern Marianas Islands, and American Samoa. PIs make up a grossly underrepresented minority group, often being overshadowed by their mainland Asian counterparts when aggregated together as a group defined as “AANHPI” in sociological and epidemiological data sets and studies. In addition, Pacific Islanders, at least in the mainland US, are considered a “new” minority population, and with the exception of those indigenous to US territories, the vast majority of the population are post 1970 first or second generation immigrants. Research into health disparities in the PI community is thus unsurprisingly sparse, and there is great work to be done to explore these alarming trends. The purposes of this study are threefold: further explore the data pertaining to prostate cancer prevalence in the pacific islander community; disaggregate the data between ethnic lines; and provide a foundation for future research that can further elucidate the causes and outcomes of this disease in the Pacific Islander community. Data was taken from the 2014 Native Hawaiian and Pacific Islander National Health Interview Survey (NHPI NHIS). The NHPI NHIS is a national survey administered by the CDC-NCHS to collect disease data including health condition and characteristics, health care access and service utilization but specific to the national NHPI population. Among 2588 participants, 4% indicated ever having been diagnosed with cancer among which prostate cancer was the second most commonly diagnosed. This study relies heavily on large-scale national questionnaires, thus future research should incorporate additional qualitative exploratory research, including targeted and ethnicity-specific canvassing and interviews in order to better understand the real life manifestations of the disease. The preliminary findings highlight an ever growing concern for the health outcomes of this community, and provide compelling evidence in support for both disaggregation of the community from Asian Americans, as well as interethnic disaggregation in data sets. A common thread of distancing between PI communities and the healthcare system was particularly evident, raising the concern that PIs are not being screened early enough and are not seeking life saving medical attention until advanced disease progression. A hopeful outcome of this study is a recognition that more outreach and community work must be done to bridge the gap between PIs and the Western healthcare system in order to mitigate the observed disparities.
