Introduction: This study aimed to examine the associations of dietary magnesium (Mg) intake and serum Mg concentration with the high-sensitivity C-reactive protein (hsCRP) level in early radiographic knee osteoarthritis (OA) patients. Methods: Multivariable logistic regression was used to test the associations of dietary and serum Mg with the serum hsCRP in early radiographic knee OA patients after adjustment of a number of potential confounding factors. Results: A total of 936 early radiographic knee OA patients were included. A significant association between dietary Mg intake and hsCRP was observed. The multivariable-adjusted odds ratio (OR) (95% CI) for elevated hsCRP (3.0 mg/l) in the second, third, fourth, and fifth dietary Mg intake quintile were 0.44 (95% CI: 0.24-0.82), 0.58 (95% CI: 0.31-1.10), 0.34 (95% CI: 0.15-0.77), and 0.19 (95% CI: 0.06-0.57), respectively, compared with the lowest (first) quintile, and p for trend was 0.01. A significant association between serum Mg concentration and hsCRP was observed. The multivariable-adjusted OR (95% CI) for elevated hsCRP in the second, third, fourth, and fifth serum Mg concentration quintile were 0.63 (95% CI: 0.35-1.12), 0.83 (95% CI: 0.50-1.39), 0.53 (95% CI: 0.31-0.91), and 0.46 (95% CI: 0.25-0.85), respectively, compared with the lowest quintile, and p for trend was 0.01. Conclusion: The present study indicated that both dietary and serum Mg were inversely associated with serum hsCRP in early radiographic knee OA patients. [ABSTRACT FROM AUTHOR]
