Sumario: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.
