Popis:	Objective. To assess the repeatability of the validated Flinders Calcium Food Frequency Questionnaire(FFQCA)for estimating dietary calcium intake in a sample of community dwelling older Australians.Methods. A test-retest repeatability study involving 100 subjects (≥65 years) living independently in metropolitan Adelaide, Australia. Estimates of daily calcium intake from the first(FFQCA1)and repeated administration(FFQCA2)were calculated from two versions (35-item and 15-item) of theFFQCA. The intraclass correlation coefficient (ICC) was used to assess the repeatability.Results. Moderate and comparable ICC values (r=0.5,r=0.6) were found across the two versions of theFFQCA.Conclusion. BothFFQCAversions demonstrated moderate repeatability, supporting the results of previous studies.
