Demographic, Dietary, and Urinary Factors and 24-h Urinary Calcium Excretion

Demographic, dietary, and urinary factors and 24-h urinary calcium excretion.

BACKGROUND AND OBJECTIVES Higher urinary calcium is a risk factor for nephrolithiasis. This study delineated associations between demographic, dietary, and urinary factors and 24-h urinary calcium. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Cross-sectional studies were conducted of 2201 stone formers (SF) and 1167 nonstone formers (NSF) in the Health Professionals Follow-up Study (men) and...

Association of Serum Calcium and 24 Hours Urinary Excretion of Calcium in Patients of Preeclampsia

ORIGINAL ARTICLE Bangladesh J Med Biochem 2010; 3(2): 57-60 premature delivery. In the developing countries, preeclampsia affects 4.4 percent of all deliveries and may be as high as 18 percent in some settings in Africa4. Development of a simple and reliable biochemical test is, therefore, important to detect pregnant women in the early stage of preeclampsia. Several biochemical changes occur d...

Determinants of 24-hour urinary oxalate excretion.

BACKGROUND AND OBJECTIVES Higher levels of urinary oxalate substantially increase the risk of calcium oxalate kidney stones. However, the determinants of urinary oxalate excretion are unclear. The objective was to examine the impact of dietary factors, age, body size, diabetes, and urinary factors on 24-h urinary oxalate. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS We conducted a cross-se...

Effect of Variation in Dietary Calcium on Plasma Concentration and Urinary Excretion of Calcium.

Association between Parent and Child Dietary Sodium and Potassium Intakes as Assessed by 24-h Urinary Excretion

The aim of this study was to assess the association between parent and child sodium (Na) and potassium (K) intake as assessed by 24-h urinary excretion (24hUE). Primary school children and their parent(s) provided one 24-h urine sample and information on cooking and children's discretionary salt use. Valid urine samples were provided by 108 mothers (mean age 41.8 (5.1) (SD) years, Na 120 (45) m...
