Abstract
Background. Very few studies have evaluated the role of urinary calcium excretion as marker of bone metabolism in children. Normative data are lacking in these age groups. Methods. In a group of 122 children (66 females e 56 males), mean age 108.13±18.73 months, attending a primary school in Nocera Superiore (Southern Italy) the following parameters were evaluated: sex, age, weight, height, BMI (weight/height2), urinary calcium excretion which was measured as the urinary calcium/creatinine concentration ratio (Uca/cr) in extemporaneous sample of the second urine in the morning. The Uca/cr ratio was not normally distributed in this childhood population. Natural logarithmic transformation was used to analyze the data. Results. The mean value of Uca/cr was 0.125±0.102 mg/mg. A significant correlation was found between the Uca/cr ratio and sex. The Uca/cr ratio values were higher in girls than in boys. Mean Uca/cr was 0.144±0.113 mg/mg in females while it was 0.102±0.083 mg/mg in males ("t"-test: p
