Diet‐related chronic diseases are at epidemic levels in low‐income ethnic minority populations. The purpose of this study is to decrease risk for obesity in children by modifying the food environment and conducting point‐of‐purchase promotions that will lead to changes in psychosocial factors and behaviors associated with healthier food choices among low‐income communities with a preponderance of Native Hawaiians and Pacific Islanders. We implemented an intervention trial over a 9–11‐month period in five food stores in two low‐income multiethnic communities in Hawaii, targeting both children and their adult caregivers. The Healthy Foods Hawaii (HFH) intervention consisted of an environmental component to increase store stocking of nutritious foods, point‐of‐purchase promotions, interactive sessions, and involved local producers and distributors. We evaluated the impact of the program on 116 child–caregiver dyads, sampled from two intervention and two comparison areas before and after intervention implementation. Program impacts were evaluated using multivariable linear regression. The HFH program had a significant impact on caregiver knowledge and the perception that healthy foods are convenient. Intervention children significantly increased their Healthy Eating Index (HEI) score for servings of grains, their total consumption of water, and showed an average 8.5 point (out of 90 total, eliminating the 10 points for variety, giving a 9.4% increase) increase in overall HEI score. A food store intervention was effective in improving healthy food knowledge and perception that healthy foods are convenient among caregivers, and increased the consumption of several targeted healthy foods by their children. Greater intensity, sustained food system change, and further targeting for children are needed to show greater and sustained change in food‐related behaviors in low‐income Native Hawaiian and Pacific Islander communities.
The Pacific Tracker (PacTrac) is a new dietary assessment program that can be used to evaluate dietary data for nutrition studies in the Pacific Islands. PacTrac is a modification of the Interactive Healthy Eating Index (IHEI) developed by the US Department of Agriculture's Center for Nutrition Policy and Promotion as an online interactive dietary assessment tool for use by the public. Creation of PacTrac required several modifications to the IHEI, including a function to save data to allow for later access and addition of Pacific Island foods. Sources for Pacific Island foods included the Cancer Research Center of Hawaii (CRCH) Food Composition Table (FCT) and recipes from Guam and the Commonwealth of the Northern Mariana Islands (CNMI). Initially, 344 foods in the CRCH FCT were added to the IHEI. Feedback from pilot sessions indicated it was too large and therefore difficult to navigate. Therefore, we removed the original IHEI database (over 7000 foods) and replaced it with the CRCH FCT (2778 foods) plus 85 recipes from Guam and 40 recipes from CNMI. We are currently using PacTrac to evaluate dietary data in Hawaii, Guam and CNMI.
