Associations of dietary magnesium intake with mortality from cardiovascular disease: the JACC study.
The authors sought to investigate the relationship between dietary magnesium intake and mortality from cardiovascular disease in a population-based sample of Asian adults. Reported findings are based on dietary magnesium intake in 58,615 healthy Japanese aged 40-79 years, in the Japan Collaborative Cohort (JACC) Study. Dietary magnesium intake was assessed by a validated food frequency questionnaire administered between 1988 and 1990. ⋯ The multivariable hazard ratio (95% CI) for the highest vs. the lowest quintiles of magnesium intake after adjustment for cardiovascular risk factor and sodium intake was 0.49 (0.26-0.95), P for trend = 0.074 for hemorrhagic stroke in men, 0.68 (0.48-0.96), P for trend = 0.010 for total stroke, 0.47 (0.29-0.77), P for trend < 0.001 for ischemic stroke, 0.50 (0.30-0.84), P for trend = 0.005 for coronary heart disease, 0.50 (0.28-0.87), P for trend = 0.002 for heart failure and 0.64 (0.51-0.80), P for trend < 0.001 for total cardiovascular disease in women. The adjustment for calcium and potassium intakes attenuated these associations. In conclusion, dietary magnesium intake was associated with reduced mortality from cardiovascular disease in Japanese, especially for women.
