Examination of the validity of the Japanese version of the IPA questionnaire for the evaluation of the physical activity of diabetes patients

Abstract

[Purpose] We investigated whether the International Physical Activity Questionnaire (IPAQ) was valid for use in assessing the physical activity levels of diabetes patients, who are expected to have reduced physical activity. [Subjects] The subjects were 16 type 2 diabetes mellitus patients. [Method] Using Pearson;s correlation coefficient and Student's t-test we investigated the correspondence of 1-week exercise energy consumption calculated from the Short Version of the Japanese IPAQ, and 1-week exercise energy consumption calculated by a Suzuken Lifecorder GS/Me. [Results] We found no significant difference between the two measures according to the Student's t-test result, and the correlation coefficient for the two measures was, r=0.69. [Conclusion] The level of physical activity of diabetes patients calculated from IPAQ was confirmed and validated against the level of physical activity measured by Lifecorder. © 2013 by the Society of Physical Therapy Science.
