Translating diabetes prevention into native Hawaiian and Pacific Islander communities: the PILI 'Ohana Pilot project.

BACKGROUND: Native Hawaiians (NH) and Other Pacific Islanders (OPI) bear an excess burden of diabetes health disparities. Translation of empirically tested interventions such as the Diabetes Prevention Program Lifestyle Intervention (DPP-LI) offers the potential for reversing these trends. Yet, little is known about how best to translate efficacious interventions into public health practice, particularly among racial/ethnic minority populations. Community-based participatory research (CBPR) is an approach that engages the community in the research process and has recently been proposed as a means to improve the translation of research into community practice. OBJECTIVES: To address diabetes health disparities in NHOPIs, CBPR approaches were used to: (1) culturally adapt the DPP-LI for NHOPI communities; and (2) implement and examine the effectiveness of the culturally-adapted program to promote weight loss in 5 NHOPI communities. METHODS: Informant interviews (n=15) and focus groups (n=15, with 112 NHOPI participants) were completed to inform the cultural adaptation of the DPP-LI program. A team of 5 community investigators and 1 academic research team collaboratively developed and implemented the 12-week pilot study to assess the effectiveness of the culturally adapted program. RESULTS: A total of 127 NHOPIs participated in focus groups and informant interviews that resulted in the creation of a significantly modified version of the DPP-LI, entitled the PILI 'Ohana Lifestyle Intervention (POLI). In the pilot study, 239 NHOPIs were enrolled and after 12 weeks (post-program), mean weight loss was -1.5 kg (95%CI -2.0, -1.0) with 26% of participants losing > or = 3% of their baseline weight. Mean weight loss among participants who completed all 8 lessons at 12 weeks was significantly higher (-1.8 kg, 95%CI -2.3, -1.3) than participants who completed less than 8 lessons (-0.70 kg, 95%CI -1.1, -0.29). CONCLUSION: A fully engaged CBPR approach was successful in translating an evidence based diabetes prevention program into a culturally relevant intervention for NHOPI communities. This pilot study demonstrates that weight loss in high risk minority populations can be achieved over a short period of time using CBPR approaches.

Partnerships to address obesity disparities in Hawai'i: the PILI 'Ohana Project.

Community-based participatory research (CBPR) is an approach to scientific research that is gaining broader application to address persistent problems in health care disparities and other hypothesis-driven research. However, information on how to form CBPR community-academic partnerships and how to best involve community partners in scientific research is not well-defined. The purpose of this paper is to share the experience of the Partnership for Improving Lifestyle Interventions (PILl) 'Ohana Project in forming a co-equal CBPR community-academic partnership that involved 5 different community partners in a scientific research study to address obesity disparities in Native Hawaiians and other Pacific Peoples (i.e., Samoans, Chuukese, and Filipinos). Specifically, the paper discusses (1) the formation of our community-academic partnership including identification of the research topic; (2) the development of the CBPR infrastructure to foster a sustainable co-equal research environment; and (3) the collaboration in designing a community-based and community-led intervention. The paper concludes with a brief summary of the authors' thoughts about CBPR partnerships from both the academic and community perspectives.

Epidemiologic and clinical factors associated with chronic kidney disease among Asian Americans and Native Hawaiians.

OBJECTIVE: To examine the association between key susceptibility factors and measures of chronic kidney disease in Asian American and Native Hawaiian participants enrolled in the Hawai'i site of the national Kidney Early Evaluation Program (KEEP-2) study community screening program. DESIGN: In 2001-2003, 793 participants from five ethnic groups (Japanese, Native Hawaii an, Chinese, Filipino and Caucasian) were enrolled in the Hawai'i KEEP-2 program. Odds ratios were used as the measure of association and were computed using unconditional logistic regression. Renal susceptibility factors for chronic kidney disease were included in a multivariable model if found to be statistically significant in univariate analysis. The proportion of Hawai'i KEEP-2 study participants manifesting various clinical characteristics were compared by ethnicity with Japanese as the referent group. RESULTS: Significant ethnic differences in the occurrence of chronic kidney disease were found, with Japanese having the lowest occurrence of chronic kidney disease (18%) and Native Hawaiians the highest (40%). Within each ethnic group, the occurrence of chronic kidney disease was associated with a different ethnic-specific clustering of susceptibility factors. Hypertension was associated with chronic kidney disease among four of the five ethnic groups: Japanese, Caucasian, Native Hawaiian and Filipino. Overweight was associated with a decreased occurrence of chronic kidney disease among Caucasians, while diabetes and lower educational attainment were associated with increased occurrence of chronic kidney disease among Native Hawaiians. For Filipinos, diabetes and age 65 years and older were both associated with an increased occurrence for chronic kidney disease while lower educational attainment was associated with a reduced occurrence of chronic kidney disease. Among Chinese, no factors were significantly associated with chronic kidney disease, although trends for all factors paralleled those of the overall study group. CONCLUSIONS: The occurrence of chronic kidney disease in the Hawai'i KEEP-2 study was nearly fourfold greater compared with the general US population. The clustering of susceptibility factors for chronic kidney disease occurrence was found to differ for all five ethnic groups.
