- Brief Summary
Native Hawaiians' traditional lifestyles and diets ensured the mutual health and well-being of the land and its inhabitants, which stand in stark contrast to the disproportionately high prevalence of diet-related, cardiometabolic diseases they experience today. In this project, the investigators will adapt and test an evidence-based multilevel intervention entitled PILI 'Āina to improve the self-management of prevalent cardiometabolic diseases and reduce risk factors for developing new diet-related illnesses and implement and evaluate the impact and sustainability of community-wide cooking demonstrations. The objectives of this project are to optimize the effectiveness and sustainability of PILI 'Āina, improve diet quality, cardiometabolic markers, promote traditional Native Hawaiian diets, and improve social cohesion.
- Detailed Description
The investigators will conduct a group-randomized controlled trial to test the effectiveness of PILI Aina for improving diet and health at the individual and household levels compared to a Diabetes Prevention Program Lifestyle Intervention only group. The investigators will enroll 180 Native Hawaiian adults with overweight or obesity and at least 1 other diet-related cardiometabolic condition (Type 2 diabetes, pre-diabetes, hypertension, pre-hypertension, dyslipidemia). These index participants will receive the 3-month educational program and then be randomized at the household level to the 6-month PILI Aina intervention or to a control group. Data collection will occur at baseline and 3, 9, and 12 months. Other adult household members will be invited to participate in data collection at the same time to evaluate household-level effects.

Household participants must live in an index participant's household. Index participants are allowed to have up to 3 household participants.
- Primary Outcome Measures
Name Time Method Household Food Patterns Month 3, Month 9, Month 12 Household food patterns will be measured by 4 questions that assess the frequency of meal planning, eating meals with household members, bringing prepared restaurant foods home, and preparing meals with household members. The responses and scores range from 1- 1 day, 2- 2-3 days, 3- 4-5 days, 4- 6 days, 5- 7 days. Higher scores indicate greater household food patterns.
Food insecurity Month 3, Month 9, Month 12 Food insecurity will be measured by the 10-item Household Food Security Survey Module, which captures the qualitative and quantitative dimensions of household food supply, including psychological and behavioral responses of household members, and generates a binary indicator of food insecurity at the household level. The responses and scores range from 1-often true, 2-sometimes true, 3-never true. Higher scores indicate low food insecurity.
Nutrition Environment Month 3, Month 9, Month 12 The perceived 9-item nutrition environment will be measured by the Gustafson Perceived Nutrition Environment Measures questionnaire, which examines perceived access and availability of healthy foods within \~1 mile of the participant's home, and the availability and affordability of produce in the participant's primary food store. The responses and scores vary depending on the question including 0- disagree, 1-agree, and 0-not important, 1-slightly important, 2-moderately important, 3- important, 4-very important. Higher scores indicate higher perceived access and availability of food.
Physical Activity Month 3, Month 9, Month 12 The 3-item Physical Activity Questionnaire, which has been used with Native Hawaiians, will assess exercise frequency during the past month. It contains 3 items that assess moderate and vigorous exercise and changes in activity levels. The responses and scores vary depending on the question, including 0- rarely or never, 1- 2-3 times over the month, 2- about once a week, 3- 2-4 times a week, 4- more than 4 times a week. Higher scores indicate greater physical activity.
