The relationship between dietary intake and urinary excretion of sodium, potassium, calcium and magnesium: Belgian Interuniversity Research on Nutrition and Health. 1990

Division of Epidemiology, School of Public Health, University of Leuven, Belgium.

During an epidemiological survey, the dietary intake and urinary excretion of sodium, potassium, calcium and magnesium were measured by means of the 24 h food record method and a 24 h urine collection in 2,112 men and 1,943 women. Significant correlations (P less than 0.001) were found between dietary intake and urinary excretion of the above cations in men and women by univariate analysis and after adjustment for age, height, weight and total caloric intake. Taking into account the difficulty of estimating dietary cation intakes and obtaining complete 24 h urine collections, and the non-coincidence of the 24 h urine collection and the food recording periods, our findings point to a strong positive association between dietary intake and urinary excretion of sodium, potassium, calcium and magnesium. No significant relationship was found between these urinary cations and blood pressure.

UI	MeSH Term	Description	Entries
D008274	Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D001794	Blood Pressure	PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS.	Systolic Pressure,Diastolic Pressure,Pulse Pressure,Pressure, Blood,Pressure, Diastolic,Pressure, Pulse,Pressure, Systolic,Pressures, Systolic
D001827	Body Height	The distance from the sole to the crown of the head with body standing on a flat surface and fully extended.	Body Heights,Height, Body,Heights, Body
D001835	Body Weight	The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.	Body Weights,Weight, Body,Weights, Body
D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
