[Bone mineral density (BMD) of the calcaneus bone in 72 dialysis patients measured by ultrasonic bone absorptiometry].
BACKGROUND
To determine what factors contribute to and change BMD in dialysis patients.


METHODS
Bone parameters, namely, osteosono-assessment index (calculated by speed of sound and transmission index) were measured at calcaneus bone by ultrasonic bone absorptiometry with an Aloka Acoustic Osteoscreener (Model AOS-100). Seventy two patients were 62. 8 +/- 10.5 years of age (mean +/- SD) (range 36-81) and 70.8% were males; the patients had received dialytic therapy for 52.7 +/- 41.7 months (range 2-205). The effects of sex, age, height, weight, postmenoposal years, dialysis duration, various blood parameters, oral phosphorus binding agent (CaCO3 dosage) and oral vitamin D3 treatment (D3 dosage) on BMD were assessed statistically.


RESULTS
BMD in male patients were significantly higher than those in female patients (Mann-Whitney test, p < 0.01). BMD showed significant correlations with age (Spearman's correlation coefficient r = -0.384, p < 0.01), height (r = 0.479, p < 0.00001), postmenoposal years (r = -0.692, p < 0.05), dialysis duration (r = 0.250, p < 0.01), blood Ca level (r = 0.292, p < 0.05) and CaCO3 dosage, postmenoposal years and dialysis duration were the variables that significantly correlated with the BMD (multiple correlation coefficient = 0.646).
