Association of the 2020 Healthy Eating Index with asthma in children and adolescents in the United States: a cross-sectional study of NHANES

Our goal was to investigate the connection between asthma and HEI-2020. A cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2020. Diet quality was measured as HEI-2020 scores using 24-h and 2-day dietary recall data. A range of statistical methods, including as sensitivity analysis, restricted triple spline analysis, subgroup analysis, and multivariate logistic regression, were used to assess the relationship between the HEI-2020 and asthma. 2,740 (17.5%) of the 15,667 said a doctor or other health care provider had diagnosed them with asthma.

The adjusted odds ratios (OR) for asthma in the second (Tertiles 2, 42.92– There is a negative correlation between asthma and the Healthy Eating Index-2020 in children and adolescents in the United States.
