The Magnesium Depletion Score is associated with increased likelihood of kidney stone disease among female adults

Abstract

Abstract Object: The association between magnesium depletion score (MDS) and kidney stone disease (KSD) remains unknown. This study was designed to investigate the association of MDS with KSD in adults. Methods: A total of 19,654 participants were enrolled from the National Health and Nutrition Examination Surveys (NHANES). The MDS was calculated by assessing four aspects, including alcohol assumption, renal function, and use of diuretics and proton pump inhibitor (PPI). Multivariable logistic regressions were performed to explore the associations between MDS and the prevalence of KSD. Linear correlations were conducted explore the relationship of testosterone with MDS. Results: In the multivariable logistic regressions with full adjustment for confounding variables, the odds ratio of MDS associating with KSD was 1.28 (95% CI: 1.04–1.58, P = 0.022) in total population, and 1.70 (95% CI: 1.16–2.50, P = 0.007) in female participants. Besides, compared to the lowest MDS, the highest MDS was associated with a lower testosterone (β = -11.548, P = 0.001) after full adjustment in non-menopause women. Conclusion: This study highlighted a positive correlation of high MDS with KSD in female population, which may be associated low level of serum testosterone.
