Abstract
Objective: The purpose of this study was to validate the short and long version of the IPAQ in adults with diabetes in Tijuana.Methods: Direct interview of the short version (IPAQ-S) and long (IPAQ-L) version was applied twice over a period of five days. The participants wore an Actigraph accelerometer (AA) model GT1M during seven days. Data from accelerometer was processed usingActilife v4.4.1 and Meterplus v4.0 software. The test-retest reliability and the validity of the questionnaires were assessed using the Spearman’s correlation coefficient.Results: 31 subjects with type 2 diabetes participated in the study. The mean age was 51.5 years old and BMI was 30.8 Kg/m2. The tes-retest results for the IPAQ-S were for vigorous PA 0.89(p=0.0001), for light PA 0.74(p=0.001), for the IPAQ-L were for vigorous PA 0.74 (p=0.0001), for light PA 0.70 (p=0.01), for moderate PA was 0.69 (p=0.02). The correlation coefficients between AA counts/min/d with moderate PA from IPAQ-S and IPAQ-L were 0.37 (p=0.04) and 0.39 (p=0.03) respectively.Conclusions: Although it was shown a good reproducibility there was modest significant correlations between the direct measures of PA and the questionnaires for moderate and light PA.
