Objective. To assess the repeatability of the validated Flinders Calcium Food Frequency Questionnaire (FFQ CA) 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 (FFQ CA1) and repeated administration (FFQ CA2) were calculated from two versions (35-item and 15-item) of the FFQ CA. 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 the FFQ CA. Conclusion. Both FFQ CA versions demonstrated moderate repeatability, supporting the results of previous studies.
