Calcium and deoxipyridinoline in three different samples of urine and calcium intake: Interrelationship

Abstract:

This study was carried out in 14 healthy, premenopausal women, aged 22-35 years, living in Comodoro Riuadavia (46degrees South Latitude). They had body weight: 57.7 +/- 3.8 Kg; BMI: 21.8 +/- 1.7 kg / m(2) and normal femoral neck and lumbar spine (L2-L4) bone mineral density. Usual daily Calcium intake (CaI) was calculated according to a dietary survey and the National Food. Composition Tables. The following samples of urine were collected in successive days: (A), basal (the second in the morning, with fasting of liquids and solids); (B) the second in the morning after drinking 200 ml of water; (C), that of 24-h collection. Calcium (Ca), creatinine (crea) and deoxypiridinoline (D-Pyr) were determined; Ca/crea and D-Pyr/crea were calculated. The results as mean value standard deviation (ranges) were: CaI (mg/d): 720 284; Ca/crea (mg/mg) A: 0.065 +/- 0.039, B: 0.050 +/- 0.022, C: 0.089 +/- 0.027, D-Pyr/crea …
