- Abstract
Objectively measured population physical activity (PA) data is lacking in Malaysia. Objective measurement is currently viewed as the minimum standard for PA assessment in epidemiological research because it decreases the element of bias commonly found through self-report methods. The aim of this study was to determine the feasibility of measuring physical activity (PA) level and sedentary behaviour of Malay adults using an ActiGraph GT3X accelerometer. All twenty participants (mean age 58.6 ± 18.1 years) in the study were compliant in wearing the accelerometer for at least 12 hours per day for 7 consecutive days, and the desired PA parameters were properly measured. All subjects were sedentary for 59 % of the wear time. Participants spent on average 24 minutes daily at a moderate intensity of PA and at least one bout of sustained 10 minutes of PA per week. Mean activity counts per minute were in the 'light intensity' category (vector magnitude 486.7 ± 170.3) and step counts per day were in the 'active' category (12,462.0 ± 3,813.0 steps). Overall, the results demonstrate that participants are generally inactive and the high compliancy means that the use of accelerometers is feasible for studying the PA level of the Malay adult population.
