夏威夷原住民的超重/肥胖率几乎为75%。过度肥胖与癌症风险增加和癌症预后不良有关。我们提出了一项随机对照试验(RCT)，以适应和测试基于证据的减肥干预措施，用于夏威夷的土著服务组织，使用基于社区的参与性研究(CBPR)方法。这项拟议的为期5年的研究是根据我们之前两个由NIH资助的项目--设计健康工作场所(DHW)--的结果而提出的。项目和PILI生活方式干预(PILI)。PILI已经在夏威夷的土著社区进行了改造和测试。这项提案将在那些表示有兴趣建立工作场所健康计划的夏威夷原住民服务的工作场所进行调整和测试。具体来说，我们将 1)在夏威夷原住民服务组织中调整和实施菌毛丢失和菌毛维护，与员工代表合作，确定如何最好地对工作场所的员工实施干预(菌毛丢失和菌毛维护一起称为PILI(G)工作)。 2)在参与PILI@Work的员工中，测试DVD格式的PILI维护是否与集团中的PILI维护一样有效地为完成PILI Wt减肥的员工保持减肥效果。 在成功完成后，我们希望展示减肥后的维护计划可以使用简单的技术，如DVD或同龄人小组教师来维持。我们希望这些调查结果可以推论到其他太平洋岛民社区，或者可能是全国和更广阔的太平洋地区的其他土著社区。未来的研究可能包括基于我们目前的PILI@Work研究的设计和实施，在部落或其他太平洋岛民社区进行的文化定制项目。我们还设想在工作场所使用DVD来鼓励有超重、肥胖或其他慢性健康问题风险的员工的其他健康行为。

Prevalence of overweight/obesity in Native Hawaiians is almost 75%. Excess adiposity is associated with increased risks of cancer and poor cancer outcomes. We propose a randomized control trial (RCT) to adapt and test an evidence-based weight loss intervention for use in Native Hawaiian-serving organizations in Hawai'i, using a community-based participatory research (CBPR) approach. The proposed 5-year study is informed by findings from our two previous NIH-funded projects CThe Designing Healthy Worksites (DHW) . Project and The PILI Lifestyle Intervention (PILI). PILI already has been adapted and testing in Native Hawaiian communities in Hawaii. This proposal would adapt and test it in Native Hawaiian-serving worksites who have expressed an interest in establishing worksite wellness programs. Specifically, we will 1) Adapt and implement PILI Wt Loss and PILI Maintenance in Native Hawaiian-serving organizations, working with employee representatives to determine how the intervention can be best implemented with employees in worksites (PILI Wt Loss and PILI Maintenance together wdll be called PILI(g)Work). 2) Among employees participating in PILI@Work, to test whether PILI Maintenance in DVD format is as effective as PILI Maintenance in Group in maintaining weight loss for employees who complete PILI Wt Loss. Upon successful completion, we hope to demonstrate that maintenance programs after weight-loss can be sustained using simple technology, such as DVDs or peer group instructors. We expect that these findings can be extrapolated to other Pacific Islander communities or perhaps other Native communities nationwide and in the broader Pacific. Future studies could include culturally-tailored programs in tribal or other Pacific Islander communities based on the design and implementation of our current PILI@Work study. We also envision use of DVDs at the workplace to encourage other healthy behaviors among employees at risk for overweight, obesity, or other chronic health conditions.
