Background: Low‐income racially and ethnically diverse children are at higher risk for obesity compared with their counterparts; yet, few studies have assessed their diet quality.Objective: The aim of the study was to evaluate the diet quality of a racially and ethnically diverse cohort of 2‐year‐olds using the Healthy Eating Index (HEI)‐2010.Methods: We used 24‐hour dietary recall data from caregivers of toddlers (24–34 months) at 4 pediatric resident clinics that participated in the Greenlight Study to calculate compliance with the Dietary Guidelines for Americans (DGA) using total HEI score (range 0–100) and 12 component scores.Results: Participants (n = 231) were mostly Hispanic (57%) or non‐Hispanic black (27%) and from low‐income families. Mean HEI‐2010 score was 62.8 (standard deviation [SD] 10.5). Though not significant, Hispanics had the highest HEI score. Toddlers of caregivers without obesity, older than 35 years and born outside the United States had higher HEI scores. Most had high HEI component scores for dairy, fruit, and protein foods, but few achieved maximum scores, particularly for whole grains (13%), vegetables (10%), and fatty acid ratio (7%).Conclusions: Despite scores reflective of DGA recommendations for fruit, dairy and protein foods, toddlers in this diverse sample had low quality diets as measured by the HEI, driven largely by low component scores for whole grains, vegetables, and ratio of unsaturated to saturated fatty acids.

Background: Little is known about intended breastfeeding duration of women who initiate breastfeeding. We describe the association between intended and actual breastfeeding duration among low-income, diverse mothers who report maintaining breastfeeding for the first 2 months postpartum. Materials and Methods: We included mothers (64% Hispanic, 17% non-Hispanic black) participating in Greenlight, a cluster randomized childhood obesity prevention trial, who were providing breast milk at the 2-month preventive service visit and reported intended breastfeeding duration at this visit. Breastfeeding status was assessed at subsequent visits, up to 24 months. Poisson regression with a robust variance estimator was used to estimate risk ratios and 95% confidence intervals for meeting breastfeeding intentions. Covariates included race/ethnicity, income, receiving benefits from the Special Supplemental Nutrition Assistance Program for Women, Infants and Children (WIC), education, age, employment, depression, maternal obesity, U.S. born, whether infant was first born, and study site. Results: Median intended breastfeeding duration was 11.5 months (interquartile range [IQR]: 6–12) and median actual breastfeeding duration was 8.6 months (IQR: 4–14) (n = 349). Approximately half (49%) met intended breastfeeding duration. Breastfeeding duration differed based on milk type provided at the 2-month visit in that mothers providing mostly or only breast milk had increased likelihood of meeting breastfeeding intentions. Regardless of milk type provided at 2 months, the longer a mother intended to breastfeed, the less likely she was to meet her breastfeeding intentions. Conclusions: In this diverse sample of women less than half met breastfeeding intentions despite maintaining breastfeeding for 2 months. Understanding factors that prevent mothers from attaining intended breastfeeding duration is critical to improving breastfeeding outcomes, especially in low income and ethnic minority populations.

The chapters and reports in this book explore a wide variety of topics related to how health literacy can impact clinical practice and public health. While health literacy is relevant to healthcare issues across populations, it has unique implications in the field of pediatrics, where parents and other caregivers are responsible for managing their child's healthcare. Younger children have varying roles and involvement; over time, as children reach adolescence, they have an increasing understanding of and participation in their healthcare. This chapter will review the epidemiology of health literacy in parents, adolescents, and children, and how this compares to the general adult population. It will highlight unique considerations regarding health literacy and pediatric health. The chapter will then focus on the impact of health literacy and relevant health literacy-informed interventions on pediatric health. Finally, the chapter will discuss gaps in the literature and future directions.
