Introduction: Clinical practice guidelines recommend a daily intake of calcium of 1-1, 5 g for posmenopausical osteoporosis. However, giving the possible adverse effects of calcium supplements, their use remains controversial.

Aims: Validate the dietary assessment of calcium. Evaluate the degree of compliance of the medical advice and discuss the adequacy of prescribing calcium supplements.

Patients and methods: Sample cohort comprised 337 patients (292 women; and 45 men) recruited from consecutive patients submitted to perform a bone densitometry. Anthropometric measurements, osteoporosis risk factors, dairy intake of calcium, antecedents of bone fractures, co-morbidity, and treatments were recorded in all participants. Also, a sample of 79 female subjects was re-evaluated across the time to evaluate the adherence to the recommendation of increase the intake of Ca. Data were analyzed with the statistical package IBM-SPSS.

Results and discussion: Daily intake of calcium showed a good correlation (r=0.42; P<0.001) with information obtained by means of a 24 h dietary record administered by trained personal. Patients increased the intake of Ca from 663±321 to 762±359 mg/day, (P=0.015) after medical advice. A 24.0% of the patients were treated with anti-osteoporotic drugs and a 31.0% of them takes Ca supplements but their medical prescription has not been associated with the intake of calcium of the sample (no prescription in 86.8% of patients with dairy Ca intake <700 mg/day and 18.2% with Ca intake≥1200).

Conclusions: As patient’s follows medical recommendation, it would be useful for the future, the evaluation of the real requirement of calcium supplements before supplements prescription. The questionnaire previously used for calcium assessment seems to be valid for this purpose.
