• This study assessed the relationship between magnesium status and C-reactive protein concentration in obese and nonobese women. This cross-sectional study included 131 women, aged between 20 and 50 years, who were divided into two groups: obese ( n  = 65) and control ( n  = 66) groups. Magnesium intake was monitored using 3-day food records and NutWin software version 1.5. The plasma, erythrocyte, and urinary magnesium concentrations were determined by flame atomic absorption spectrophotometry. C-reactive protein concentration in serum was measured by immunoturbidimetric assay. The mean values of the magnesium content in the diet were lower than those recommended, though there was no significant difference between groups ( p  > 0.05). The mean concentrations of plasma and erythrocyte magnesium were within the normal range, with no significant difference between groups ( p  > 0.05). Urinary excretion of this mineral was less than the reference values in both groups, with no significant difference ( p  > 0.05). The mean concentration of serum C-reactive protein was within the normal range in both groups, with no significant difference ( p  > 0.05). There was a positive correlation between urinary magnesium and serum C-reactive protein ( p  = 0.015). Obese patients ingest low dietary magnesium content, which seems to induce hypomagnesuria as a compensatory mechanism to keep plasma concentrations of the mineral at adequate levels. The study shows a positive correlation between urinary magnesium concentrations and serum C-reactive protein, suggesting the influence of hypomagnesuria on this inflammatory protein in obese women.
