| Abstract |
International Physical Activity Questionnaire (IPAQ) was evaluated to confirm whether the instrument couldbe adapted to Korean middle aged women. 203 women (48.1±10.5 yrs, 154.5±16.2cm, 59.3±9.6kg) responded toIPAQ translated as guided and it was re-administered 1 week after the first test. The test-retest physical activity levelof this population were 4,599±6,161 and 4,444±5,825 MET-min/week, respectively (P>0.05). The test-retest correlationcoefficient was highly significant as Kappa, 0.462; Spearman, 0.566; and Pearson, 0.562 (P<0.05). When three levelsof physical activity pattern (inactive, minimally active, HEPA active) was analyzed, those who ‘minimally active’ and‘HEPA active’ were heavily relied on the activity intensities of both ‘walking’ and ‘vigorous intensity’. In conclusion,IPAQ was reliable for this population. However, the average physical activity level was higher and the standard deviationof the mean was also higher than previous reports. It may have to be careful to administer IPAQ for this particularpopulation. |
