186147 Challenges and Strategies to Oversampling Pacific Islanders for Health SurveillanceTuesday, October 28, 2008: 1:30 PM
Despite enormous health disparities experienced by Pacific Islanders (PIs) in California, there is a dearth of data to guide intervention and policy development to address them. California is second only to Hawaii in the number of Pacific Islander residents (221,458 based upon Census 2000). The California Health Interview Survey (CHIS) is the nation's largest state health survey and routinely produces relatively large samples of many Asian ethnic groups through a large statewide sample and targeted oversampling. CHIS does not, however, produce an adequate sample of PIs to calculate reliable estimates. Given the need for a scientific representative sample of PIs in California, CHIS collaborators undertook an effort to 1) develop a plan for oversampling PIs; 2) identify costs associated with the oversampling plan; and 3) promote the plan to potential funders to support implementation of a PI oversample in CHIS 2009. Oversampling strategies evaluated include geographic targeting of RDD sample, surname list sample, and social network sampling. With the input of a working group of experts in the area of Pacific Islander health and survey methodology, these strategies were evaluated for scientific rigor and feasibility. Outcomes of this process hold promise for informing the development of oversamples for other underrepresented ethnic/racial populations across the country.

Presenting author's disclosure statement:
Qualified on the content I am responsible for because: Dr. Sora Park Tanjasiri is Associate Professor in the Department of Health Science at California State University, Fullerton. Her work focuses on the community health needs of diverse populations, particularly Asian Americans and Pacific Islanders (AAPIs). Dr. Tanjasiri’s scholarship involves participatory action research principles and techniques, and health issues of interest include tobacco prevention, cancer early detection and cancer control. She is the Principal Investigator of WINCART: Weaving an Islander Network for Cancer Awareness, Research and Training, which is a five year, NCI funded U01 collaborative with 8 community-based non profit organizations and 4 other universities. Dr. Tanjasiri is also the Co-PI on a two year NIH funded R03 study to increase cervical cancer screening among Thais, a three year study to map pro- and anti-tobacco influences in Cambodian and Chamorro communities, a four year project to decrease breast, cervical, colon, prostate and liver cancers among Chinese and Koreans, and a five year CDC-funded effort to increase breast and cervical cancer screening among Southeast Asian and Pacific Islander women.
In addition to her professional work, Dr. Tanjasiri has also served as an advisor to numerous non-profit organizations and coalitions, including the Board of Directors of the Orange County Asian Pacific Islander Community Alliance, the Advisory Committee of the Asian Pacific Partners for Empowerment and Leadership (a national Asian American and Pacific Islander tobacco control network), and the Susan G. Komen Foundation’s Asian American/Pacific Islander National Advisory Committee. Dr. Tanjasiri received her masters and doctoral degrees in Community Health Sciences from the UCLA School of Public Health.
