Magnesium intake and serum C-reactive protein levels in children.

The objective of this study was to determine whether magnesium consumption is associated with inflammation (C-reactive protein [CRP]) in children. The study was an analysis of child (age 6-17 years) participants in the cross-sectional, nationally representative National Health and Nutrition Examination Survey (NHANES). Children consuming less than 75% of RDA were 1.94 times more likely (p < 0.05) to have elevated serum CRP levels than children consuming above the RDA. In adjusted analyses controlling for demographics, cardiovascular risk factors, and BMI, children with consumption of less than 75% RDA were 58% more likely to have elevated CRP (OR 1.58, 95% CI 1.07-infinity). Children with intakes below the RDA are more likely to have elevated CRP levels.
