claimThe quantitative scoring indices ELD-I and WISH show a positive, weak correlation with most PANDiet metrics, including total PANDiet score, sub-scores, and nutrient adequacies.

claimThe World Index for Sustainability and Health (WISH) was developed using data from Vietnam, incorporates quantitative scoring, adjustments for energy intake, and interchangeability between food components, and is positively associated with health indicators.

measurementWomen had significantly higher means in WISH, ELI, PHDI, and ELDS dietary index scores than men.

measurementThe WISH and ELI indices have moderate effects on the PANDiet index (η2 = 0.121 and 0.083, respectively), while the PHDI and ELD-I indices have small effects (η2 = 0.059 and 0.053, respectively).

measurementThe EAT-Lancet Diet-Index (ELD-I) and the WISH index exhibited the best internal consistency among the indices evaluated, while the ELDS index showed lower lambda coefficients.

measurementThe WISH index outperforms the EAT-Lancet Diet-Index (ELD-I) regarding the assessment of essential fatty acids.

measurementCorrelations between energy intake and other dietary indices were low (p < 0.0001): HSDI (r = -0.23), WISH (r = -0.25), ELI (r = -0.28), and ELDS (r = -0.30).

measurementThe ELD-I index had the highest split-half reliability (λ4 = 0.57), followed by WISH (λ4 = 0.47), ELI (λ4 = 0.47), and PHDI (λ4 = 0.46).

claimThe WISH dietary index showed significant differences across quartiles, but trends were ruled out for terrestrial eutrophication and fossil resource indicators.

measurementThe indices based on EAT-Lancet recommendations are generally negatively correlated with the Product Environmental Footprint (PEF) and 14 individual environmental metrics (highest ρ = −0.33), except for water use and photochemical ozone formation, which showed positive correlations for the WISH and ELI indices.

claimStructural Equation Modeling (SEM) confirmed the unidimensional structural validity of the WISH, PHDI, ELD-I, and ELI dietary indices.

referenceThe World Index for Sustainability and Health (WISH) is a quantitative scoring index consisting of 13 food components, where each component is scored on a scale from 0 (non-compliance) to 10 (full compliance) based on reference values in grams that account for both healthiness and environmental sustainability.

measurementNon-smokers have higher mean scores for WISH, ELD-I, and ELI dietary indices.

measurementSignificant positive correlations were found between the PANDiet adequacy sub-score (Mean = 63.42; SD = 12.10) and the WISH, PHDI, ELD-I, and ELI indices, with ρ ranging from 0.07 to 0.17.

measurementThe WISH index has its main effects on vitamin C, the moderation subscore, and sugars; the PHDI index has its main effect on fiber and vitamin C; and the ELD-I index shows positive trends with moderate to large effect sizes for vitamin C, fiber, folate, and manganese.

claimWISH and PHDI are bounded continuous measures that restrict variability to specific values within a finite set.

measurementThe ELD-I index correlated inversely with linoleic acid, vitamin B12, phosphorus, carbohydrates, and sodium, while the WISH index correlated inversely with niacin, and the PHDI index correlated inversely with total fat.

claimThe WISH index score was lower in the study compared to the original study, potentially reflecting variations in dietary habits between France and Vietnam.

measurementThe ELD-I index showed the greatest score difference between the 1st percentile (-84.01) and the 99th percentile (74.72), followed by WISH (6.92 vs. 75.44) and PHDI (10.31 vs. 63.62).

procedureIn the World Index for Sustainability and Health (WISH), saturated fats and added sugars are scored using a binary system: 10 points if consumption is equal to or below the recommended intake, and 0 points if it exceeds it.

measurementELD-I, PHDI, and WISH explain the variability of food components at 57%, 47%, and 32% respectively, supporting their structural validity.

measurementPhysical activity levels were only related to the WISH and ELD-I dietary indices.

measurementThe total score for the World Index for Sustainability and Health (WISH) ranges from 0 to 130, with higher scores indicating greater adherence to a healthy and sustainable diet.

measurementThe WISH, PHDI, and ELD-I indices, which use quantitative scoring, were positively correlated with the adequacy of most nutrients, including polyunsaturated fatty acids, vitamins (e.g., A, thiamine, B-6, and E), and minerals (e.g., manganese, magnesium, copper, and selenium).

measurementThe WISH, PHDI, and ELD-I indices are related to an antioxidant and anti-inflammatory diet, showing positive weak correlations with the Composite Dietary Antioxidant Index (CDAI) (correlation coefficients between 0.19 and 0.25) and negative very weak correlations with the Dietary Inflammatory Index (DII) (correlation coefficients between −0.12 and −0.17).
