What is the purpose of this trial?

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.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is the PILI 'Āina Program safe for humans?

The PILI 'Āina Program, similar to other traditional Hawaiian diet programs, has shown positive health effects like weight loss and improved blood pressure without any reported safety issues. These programs focus on culturally appropriate diets and have been well-received in the Hawaiian community, suggesting they are generally safe for human use. ^{1 2 3 4 5}

How is the PILI 'Āina treatment different from other treatments for diet-related diseases?

The PILI 'Āina treatment is unique because it incorporates traditional Hawaiian dietary practices and cultural teachings, focusing on a community-based approach to address diet-related diseases. This treatment emphasizes cultural sensitivity, family support, and a whole-person approach, which are not typically found in standard treatments for these conditions. ^{1 2 3 5 6}

What data supports the effectiveness of the PILI 'Āina treatment for diet-related diseases?

The PILI 'Āina treatment is similar to the Diabetes Prevention Program Lifestyle Intervention, which has shown significant improvements in weight, blood pressure, and diet among Native Hawaiians and Pacific Islanders. This suggests that culturally tailored, community-based programs can be effective in managing diet-related diseases. ^{1 7 8 9 10}

What Are the Treatments Tested in This Trial?

Interventions

• PILI 'Āina

Trial Overview The PILI 'Āina program is being tested against a control group. The program includes adapting traditional Hawaiian lifestyles and diets through community-wide cooking demonstrations to see if they can improve diet quality and cardiometabolic health.

How Is the Trial Designed?

Group I: PILI 'Āina Experimental Treatment 1 Intervention

Participants will receive the 3-month adapted Diabetes Prevention Program's Lifestyle Intervention. At 3 months, participants randomized to the PILI 'Āina intervention will receive a 6-month intervention centered around the use of a raised-bed home garden as the means of engaging household members to 1) increase their access to and intake of vegetables, 2) learn culturally relevant ways of preparing/cooking fresh vegetables through hands-on cooking lessons with local experts, and 3) build family cohesion through family bonding activities. The participating households will be given all the equipment and materials (e.g., soil, seeds, instructions, setup of equipment) needed to grow their vegetables using their raised-bed home garden box throughout the entire study. The investigators will provide seeds for the vegetables that can grow in a relatively short period (i.e., within 6 weeks). All lessons will be delivered by a trained community health worker .

Group II: Control Active Control 1 Intervention

Participants randomized to the control group will receive monthly untailored health education information and links to community resources from the community health worker via United States Postal Service or electronic messaging. Examples include information on food assistance programs, farmers markets, cultural events, and physical activity events.

Published Research Related to This Trial

In a survey of 3,000 consumers, 17% reported experiencing adverse events from health food use, but only 11% of these cases were reported to public health centers, highlighting a significant gap in reporting.

Physicians and pharmacists often do not report adverse events due to health foods because they struggle to establish a clear cause-and-effect relationship, indicating a need for better education on the importance of reporting such incidents.
