Physical activity measurement by accelerometry among older Malay adults living in semi-rural areas-a feasibility study

We evaluated feasibility of physical activity measurement by accelerometry among older Malay adults living in semi-rural areas in Malaysia. Results showed that 95% of 146 participants (aged [SD] 67.6 [6.4] years) were compliant in wearing the accelerometer for at least fve days. Fifteen participants were asked for re-wear the accelerometer because they did not have enough valid days during the frst assessment. Participants wore the accelerometer an average of 15.3 hr in a 24-hr day, with 6.5 (1.2) valid wear days. No signifcant difference in valid wear day and time was found between men and women. Participants who are single provide more valid wear days compared with married participants (p <.05), and participants with higher levels of education provide longer periods of accelerometer wearing hours (p <.01). Eighty-seven percent of participants reported 'no issues' with wearing the meter. This study suggests that accelerometry is a feasible method to assess the physical activity level among older Malay adults living in semi-rural areas.
