Partnerships to Overcome Obesity Disparities in Hawaii: 18-month CBPR Study

University of Hawaii240 enrolled

Overview

This is a 5-year community-based participatory research intervention study with the goals of 1) conducting a more definitive study of weight loss maintenance in Native Hawaiians and Pacific Peoples and 2) identifying the aspects of the community-academic partnership that fosters a co-learning and co-equal environment.

Obesity and overweight are well recognized public health concerns in the US and the magnitude of excess weight is greater among racial/ethnic minority populations. For NHs and PPs 70 to 80% of adults are estimated to be overweight or obese. Obesity-related disparities such as diabetes and heart disease (CVD) are also increasing among NHs and PPs. To address obesity and related disparities, a community-based participatory research (CBPR) partnership was formed entitled, the Partnership for Improving Lifestyle Interventions (PILI) 'Ohana Program (Pili meaning relationship and 'Ohana meaning family). The PILI 'Ohana Program (POP) consists of 5 community organizations and the Department of Native Hawaiian Health (DNHH) at the John A. Burns School of Medicine (JABSOM) of the University of Hawai'i (UH). With a 3-year CBPR planning grant from the National Center on Minority Health and Health Disparities (NCMHD), the POP was successful at establishing this community-academic partnership aimed at obesity-related disparities in Hawai'i and in implementing a pilot intervention to address weight loss maintenance (the PILI 'Ohana Intervention) in NHs and PPs, which serves as preliminary data for this application. The specific aims are as follow: 1) To identify the aspects of the PILI 'Ohana (family + community focused) Intervention deemed effective by former participants and community-peer educators of the pilot intervention. 2) To test whether a face-to-face or DVD delivery method of the PILI 'Ohana intervention is effective in improving weight loss maintenance versus a control group in NHs and PPs. 3) To identify the strengths of the PILI 'Ohana Program that supports a co-learning and co-equal environment.

Interventions

PILI 'Ohana 18-month weight loss maintenanceBEHAVIORAL

All participants will receive a 8 lesson 3-month weight loss intervention. They will then be randomized. Those continuing with the intervention will receive 17 more lessons delivered face-to-face or via DVD over 15 months for a total of 18 months. Each lesson lasts approximately 1 hour and helps participants integrate healthy eating and physical activity into their lifestyles. Participants will also be encouraged to attend 13 community activities during the last 13 months of the intervention.
