Comparing physical activity levels of Malay version of the IPAQ and GPAQ with accelerometer in nurses
COMPARING PHYSICAL ACTIVITY LEVELS OF IPAQ, GPAQ WITH ACCELEROMETER
Objectives: There is strong evidence that regular physical activity (PA) is associated with significant health benefits for individuals of all ages. Therefore, it is necessary to have an accurate assessment of PA levels to ensure that individuals participate in sufficient PA to gain health benefits. This study compared PA levels obtained from the Malay language versions of the International Physical Activity Questionnaire (IPAQ-L: M) and Global Physical Activity Questionnaire (GPAQ: M) with those from a PA log and accelerometer. Study Design: Experimental – Cross Sectional study Methods: Data were collected from 43 female nurses aged 24 to 55 years (44.48 ± 8.38 years). In this cross-sectional study, participants answered the IPAQ-L:M or GPAQ:M and wore the accelerometer for seven consecutive days and answered GPAQ:M or IPAQ-L:M and PA log on the eight day. Physical activity levels (low, moderate and high) and total MET-min/week−1 were calculated and compared to determine if individuals have sufficient energy expenditure during Physical activity . Results: All forty three participants reported high levels of PA on both questionnaires (IPAQ-L: M = 81.4%; GPAQ: M = 67.4%). However, all participants were categorised as low PA with the Sense Wear accelerometer. There was no significant difference in the moderate (IPAQ-L: M 2.3%; GPAQ: M = 18.6%) and low (IPAQ-L: M = 16.3%; GPAQ: M = 14%) levels of PA reported in the IPAQ and GPAQ (p > 0.05). Conclusion: The PA self-assessment instruments (questionnaires) yielded high overestimation in classifying PA level and underestimation in terms of Metabolic Equivalent of Task. Therefore, when classifying people as active or inactive, special attention must be given to the assessment method used. Further study is needed to produce a more accurate subjective measure which is equivalent to objective measures like the accelerometer.
