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.

In Years 1 - 5, the investigators will hold quarterly cooking demonstrations and cultural lessons for a total of 36 events. The lessons will be aimed at improving family and community eating environments of participants and social cohesion of these communities. Attendance at each lesson will be limited to 30 individuals. Attendees will register via REDCap using their names and email addresses. There is no limit to how many lessons an individual can attend, but after the first lesson the investigators reserve 15 of the 30 spots for people who have not attended previously, as identified by their registration information. At each quarterly event, the investigators survey participants to assess their reaction to the lesson, their vegetable and fruit intake, self-efficacy for healthy diet, and perceptions of community cohesion. Surveys will take ~5-10 minutes to complete. Additionally, the investigators will survey random samples of homestead households (n = 20 per homestead, total n = 140 per year) in Projects Years 1 - 5. Total sample for this activity is 700. Each sample will be selected independent of previous samples, and it is possible the same households will be sampled multiple times.

"Hands-on Cooking and Cultural Lessons" These lessons will be widely advertised. Each 2-hour presentation will involve hands-on cooking demonstrations and tastings, accompanied by lessons on the cultural significance of featured food items. Demonstrations will link the consumption of vegetables (e.g., sweet potato, breadfruit, kalo) to Native Hawaiian (NH) history and traditional beliefs to help participants rediscover their heritage through the meals they prepare.
Time frame: Baseline, 1-year, 2-year, 3-year, 4-year
Three subscales, Cohesion, Expressiveness, and Conflict, assess the degree of commitment and support family members provide for one another, the extent to which family members are encouraged to express their feelings directly, and the amount of openly expressed anger and conflict among family members.
Time frame: Baseline, 1-year, 2-year, 3-year, 4-year
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.
Time frame: Baseline, 1-year, 2-year, 3-year, 4-year
4-item subscale of the neighborhood level stressors which asks about perceived shared values and trust.
Time frame: Baseline, 1-year, 2-year, 3-year, 4-year
The 11-item Diet Self Efficacy Scale will measure self-efficacy in avoiding tempting high caloric food and managing social and internal cues and negative emotions. The responses and scores range from 1-strongly disagree, 2-somewhat disagree, 3-neutral, 4-somewhat agree, and 5-strongly agree. Higher scores indicate greater self-efficacy with diet.
Time frame: Baseline, 1-year, 2-year, 3-year, 4-year
Food literacy, defined as the ability to make healthy food choices in different settings and situations, will be assessed by the 11-item self-perceived food literacy scale, which encompasses knowledge, skills, and behaviors pertinent to planning, selecting, preparing, and eating healthy food. The responses and scores range from 1-not at all/never, 2-disagree, 3-slightly disagree, 4- slightly agree, 5-yes/always. Higher scores indicate greater food literacy.
Time frame: Baseline, 1-year, 2-year, 3-year, 4-year
Social support for a healthy diet will be measured as the perceived support that people who make dietary changes receive from family and friends. An 11-item questionnaire on social support will be used to ask participants' perceived level of support from friends and family regarding diet choices. The responses and scores range from 1-strongly disagree, 2-somewhat disagree, 3-neutral, 4-somewhat agree, and 5-strongly agree. Higher scores indicate greater social support.
Time frame: Baseline, 1-year, 2-year, 3-year, 4-year
Cultural factors will be measured by the 4-item Cultural Identity Scale that will assess the degree of identification with NH cultural heritage. The responses and scores range from 0-not at all knowledgeable, 1- somewhat not knowledgeable, 2-neutral or no response, 3-somewhat knowledgeable, and 4-very knowledgeable. Higher scores indicate greater cultural identity.
