Overview

Cross-sectional analysis investigates urinary arsenic's association with vitamin D deficiency in adults, suggesting public health implications.

Key Points

  • This analysis aims to characterize the relationship between urinary arsenic and vitamin D deficiency in the general U.S. population.
  • Cross-sectional analysis using NHANES data from 6,148 adults aged ≥ 18 years (2011–2018)
  • Estimated odds ratios (ORs) for deficiency per interquartile-range increase in arsenic using survey-weighted logistic regression
  • Adjusted for demographics, lifestyle, dietary, and clinical factors.
  • Total urinary arsenic associated with vitamin D deficiency (OR 1.30, 95% CI 1.16, 1.45)
  • Dimethylarsinate (DMA) associated with vitamin D deficiency (OR 1.50, 95% CI 1.27, 1.78)
  • Strongest associations in women, adults <60 years, and those with certain socioeconomic factors.
