Abstract

The prevalence of (CircS) was 41.3%, decreasing from 47.3% in the lowest to 35.2% in the highest quartile of magnesium intake.

  • Higher dietary magnesium intake is linked to a lower prevalence of CircS in U.S. adults.
  • Adjusted odds ratios indicate a trend of decreasing CircS prevalence with increasing magnesium intake: 1.00, 0.80, 0.75, and 0.61 across quartiles.
  • The association between magnesium intake and CircS prevalence remains significant after adjusting for various demographic and lifestyle factors.
  • No significant interactions were found between magnesium intake and factors like race, gender, smoking, alcohol use, or physical activity.
