Key Points

  • To explore the relationship between serum vitamin D levels and asthma risk in U.S. adolescents.
  • Analyzed data from NHANES 2013-2018
  • Examined serum vitamin D levels
  • Investigated asthma prevalence
  • Utilized nonlinear modeling approaches
  • Identified a U-shaped relationship between vitamin D levels and asthma risk
  • Higher asthma susceptibility associated with both low and high vitamin D levels
  • Findings support the need for balanced vitamin D strategies

Abstract

a U-shaped relationship was observed between serum vitamin D levels and asthma risk in adolescents, suggesting that both deficiency and excess may be associated with higher susceptibility. These findings underscore the need for individualized, balanced vitamin D strategies and nonlinear modeling approaches in asthma research and public health policy.
