title: [Calcium intake of osteoporotic patients in Japan].
abstract: Osteoporotic patients appear to have low calcium intake, however, their average intake was around 750-800 mg/day investigated by food frequency questionnaire in Japanese women, and it was much higher than the analysis of the 2002 National Nutrition Survey in Japan (557 +/- 270 mg/day). Calcium intakes in these patients were widely ranged from 169 to 2,021 mg/day. The minimum is so low that high bone turnover may increase fracture risk, and the maximum is so high that renal dysfunction might occur in patients treated with active vitamin D and/or calcium supplementation. Therefore, physicians should observe carefully the patient's dietary calcium intake during the treatment with active vitamin D and/or calcium administration.
