Abstract
Background: Children's diets affect multiple health outcomes. Dietary indices are a useful tool for quantifying the quality of overall diet, but their performance may differ among children of different ages and in understudied populations.
Objectives: This analysis aimed to validate two dietary indices and examine their associations with physical body measures among 2-8-year old children of the US-Affiliated Pacific region.
Methods: Data were collected on children (n=2,359) from 5 jurisdictions of the Children's Healthy Living (CHL) randomized control trial in independent cross-sectional cluster samples over 3 time points. Anthropometric measurements were taken and dietary intakes ascertained from 2 days of dietary records completed by caregivers. The Healthy Eating Index (HEI)-2020 and Dietary Approaches to Stop Hypertension (DASH) scores were calculated using a simple scoring algorithm, their construct validity and performance were evaluated, and associations with nutrient intake, body measures and obesity status were examined using covariate-adjusted means and unconditional logistic regression.
Results: We observed a wide range of variation in DASH (9-38 points) and HEI-2020 (10-94.7 points), clear separation of mean component scores by quintile of total score and multiple dimensions for each index. Significant trends in polyunsaturated and saturated fat were observed from lowest to highest quintile of HEI-2020 (12% increase and 21% reduction, respectively) but not for DASH. Statistically significant differences by quintile of DASH and HEI-2020 were found for mean BMI z-score among 6-8-year-olds and for waist circumference among boys and 6-8-year-olds.The odds of obesity exhibited statistically significant downward trends across quintiles of HEI-2020 among all participants and in all sexes and age groups, and across quintiles of DASH among all participants, boys and 6-8-year-olds.
Conclusions: We found that HEI-2020 is a better measure of dietary intake than DASH in this population of 2-8-year-old children of the US-Affiliated Pacific region.
