Year 2009, Volume: 44 Issue: 4, 31 - 34, 01.12.2009

Abstract

Aim: Measurement of calcium creatinine ratio in spot urine sample is a practical screening method for hypercalciuria This study aimed to identify age related reference percentile values for urinary calcium creatinine ratio in healthy children and to determine the frequency of hypercalciuria Material and Method: A total of 614 children were included Second morning urine samples were collected and calcium creatinine ratio mg mg was calculated Results were examined for the following six age groups: Group 1 1 6 months; Group 2 7 12 months; Group 3 13 months 2 years; Group 4 25 months 6 years; Group 5 7 12 years; and Group 6 13 16 years Results: The mean±SD values for calcium creatinine ratios of the age groups were as follows: Group 1 0 33±0 10; Group 2 0 23±0 06; Group 3 0 15±0 08; Group 4 0 13±0 08; Group 5 0 09±0 07; and Group 6 0 08±0 07 respectively Corresponding 95th percentile values for the age groups 1 to 6 were 0 57 0 40 0 32 0 26 0 23 and 0 23 respectively Hypercalciuria prevalence was found as 4 7 in our area Urinary calcium creatinine ratio was negatively correlated with age and body mass index Conclusions: Our findings suggest that age of the child 95th percentile values and geographical differences should be taken into account in detecting the reference values for urinary calcium creatinine ratio Turk Arch Ped 2009; 44: 131 4 Key words: Children hypercalciuria urinary calcium to creatinine ratio normal values percentilee
