ABSTRACT
BACKGROUND:
Raw data from accelerometers can provide valuable insights into specific attributes of physical activity, such as time spent in intensity-specific activity. The aim of this study was to describe physical activity assessed with raw data from triaxial wrist-worn accelerometers in mid-age Australian adults.METHODS:
Data were from 700 mid-age adults living in Brisbane, Australia (mean age 60.4; SD7.1 years). Data from a non-dominant wrist worn triaxial accelerometer (Actigraph wGT3X-BT), expressed as acceleration in gravitational equivalent units (1 mg = 0.001 g), were used to estimate time spent in moderate-vigorous intensity physical activity (MVPA; >100 mg) using different bout criteria (non-bouted, 1-, 5-, and 10-min bouts), and the proportion of participants who spent an average of at least one minute per day in vigorous physical activity.RESULTS:
Mean acceleration was 23.2 mg (SD 7.5) and did not vary by gender (men 22.4; women 23.7; p-value 0.073) or education (p-value 0.375). On average, mean acceleration was 10% (2.5 mg) lower per decade of age from age 55y. The median durations in non-bouted, 1-min, 5-min and 10-min MVPA bouts were, respectively, 68 (25th -75th 45-99), 26 (25th -75th 12-46), 10 (25th -75th 3-24) and 8 (25th -75th 0-19) min/day. Around one third of the sample did at least one minute per day in vigorous intensity activities.CONCLUSION:
This population-based cohort provided a detailed description of physical activity based on raw data from accelerometers in mid-age adults in Australia. Such data can be used to investigate how different patterns and intensities of physical activity vary across the day/week and influence health outcomes.Palavras-chave
