摘要

BACKGROUND AND OBJECTIVES: Diet quality has improved over time for US adults and youth aged ≥2 years. Trends over time and disparities in the diet quality of toddlers 12 through 23 months old have not been documented. Our objective was to investigate the direction and magnitude of toddler diet quality trends from 1999 to 2018 overall and by household socioeconomic status. METHODS: This serial cross-sectional analysis of National Health and Nutrition Examination Survey (NHANES) data was performed with 2541 toddlers from 10 NHANES cycles from 1999 to 2018. Dietary intake was measured by NHANES study staff using proxy-reported 24-hour recalls. Healthy Eating Index-Toddlers-2020 total scores (0–100 points, higher scores indicate healthier diets) and component scores were calculated from the 24-hour dietary recalls using the population ratio method. Multivariable linear regression was used to evaluate the association between time in years (measured as the midpoint of each NHANES cycle) and diet quality. RESULTS: Toddler diet quality improved significantly from 1999 to 2018 (P < .001), from 63.7 points on average in 1999-2000 to 67.7 points in 2017-2018. A significant positive linear trend in total diet quality was observed for all socioeconomic status groups (P < .05). Several dietary component scores improved, as follows: Whole Fruits (P < .001), Whole Grains (P = .016), Fatty Acids (P = .002), Refined Grains (P = .009), and Added Sugars (P < .001). Scores did not significantly change for Total Fruit, Total Vegetables, Greens and Beans, Dairy, Total Protein Foods, Seafood and Plant Proteins, Sodium, or Saturated Fats. CONCLUSIONS: From 1999 to 2018, toddler diet quality improved significantly, but mean scores still fell short of dietary guidance.
