Nutrition health disparities include differences in incidence, prevalence, morbidity, and mortality of diet-related diseases and conditions. Often, race, ethnicity, and the social determinants of health are associated with dietary intake and related health disparities. This report describes the nutrition health disparities research supported by NIH over the past decade and offers future research opportunities relevant to NIH's mission as described in the Strategic Plan for NIH Nutrition Research. ⋯ The gaps and trends identified in this analysis highlight the need for future nutrition and health disparities research, including a focus on American Indian and Asian populations and the growing topics of rural health, maternal health, and food insecurity. In alignment with the Strategic Plan for NIH Nutrition Research, health equity may be advanced through innovative research approaches to develop effective targeted interventions to address these disparities.

Epidemiologic studies relating health outcomes to dietary patterns captured by diet quality indices have shown better quality scores associated with lower mortality and chronic disease incidence. However, changing chronic disease risk factors only alters population health over time, and initial diet quality systematically varies across the population by sociodemographic status. This study uses microsimulation to examine 30-year impacts of improved diet quality by sociodemographic group. ⋯ Dynamic microsimulation enables predictions of socially important outcomes of prevention efforts, most of which are many years in the future and beyond the scope of trials. This paper estimates the 30-year population health and economic impact of poor diet quality by sociodemographic group.

The Supplemental Nutrition Assistance Program; Free/Reduced Priced Lunch Program; and Special Supplemental Nutrition Program for Women, Infants, and Children reduce food insecurity for millions of Americans with lower incomes. However, critics have questioned whether they increase obesity. This study examined whether program participation was associated with BMI z-score from kindergarten to fifth grade. ⋯ Previous findings of relationships between program participation and BMI may have been because of weaker study designs and uncontrolled confounding. Participation in the Supplemental Nutrition Assistance Program; Free/Reduced Priced Lunch; and Special Supplemental Nutrition Program for Women, Infants, and Children was not associated with increased risk of childhood obesity in this recently conducted longitudinal study.

Childhood exposure to neighborhood firearm violence adversely affects mental and physical health across the life course. Study objectives were to (1) quantify racial disparities in these exposures across the U.S. and (2) assess changes during the COVID-19 pandemic, when firearm violence increased. ⋯ Large-scale racial disparities exist in child exposure to neighborhood firearm violence, and these disparities grew during the pandemic. Equitable access to trauma-informed programs, community-based prevention, and structural reforms are urgently needed.

This study examines the associations of neighborhood environments with BMI, HbA1c, and diabetes across 6 years in Hispanic/Latino adults. ⋯ Neighborhood deprivation and disorder were related to worse metabolic health in San Diego Hispanic/Latino adults of mostly Mexican heritage. Multilevel interventions emphasizing individual and structural determinants may be most effective in improving metabolic health among Hispanic/Latino individuals.
