Patients (n=62) were 53±13 yrs of age, and 40 (66%) were male. Mean dietary calcium was 1,054 mg/d (range 225-1,945 mg/d), and mean urine calcium was 250 mg/d (range 24-398 mg/d). Mean dietary sodium was 4,208 mg/d (range 2,032-7,696 mg/d), and mean urine sodium was 183 mEq/d (range 37-398 mEq/d). Most patients (61%) consumed <1,200 mg/d of calcium (the Recommended Dietary Allowance, RDA, for calcium is 1,000-1,200 mg/d for adults). Sodium intake for all patients (100%) exceeded the Adequate Intake (1,500 mg/d). When using the common risk cutoff for 24-h urine sodium (200 mEq = 4,600 mg/d), 44% consumed more than this. Nearly half (45%) of patients had hypercalciuria. Of these, calcium intake was >1,200 mg/d for 36% and < 1,000 mg/d for 50%. When patients with hypercalciuria were compared to those without (urine calcium
