The mean±SD of two continuous variables for participants who meet the MVPA, MSA guidelines and with low sedentary behaviour (≤7 hours/day) are as follows: age (51.8±0.3 for ‘meeting MVPA guideline’ group; 51.8±0.4 for ‘meeting MSA guideline’ group; 52.9±0.2 for ‘low sedentary’ group), work time per week (35.7±0.5 for ‘meeting MVPA guideline’ group; 35.6±1.0 for ‘meeting MSA guideline’ group; 38.7±0.5 for ‘low sedentary’ group).
*Values are presented as population-weighted estimated percentage (95% CI) which are given relative to the total number within each sociodemographic and work-related variable or mean±SD.
†Proportion of participants not meeting MVPA guideline (<150 min/week).
‡Proportion of participants not meeting MSA guideline (<2 days/week).
§Proportion of participants with high sedentary behaviour (>7 hours/day).
¶P values were derived from Rao-Scott χ2 test for categorical variables and the complex sample general linear model for continuous variables comparing between ‘not meeting PA guideline’ versus ‘meeting PA guideline’ or ‘high sedentary’ versus ‘low sedentary’ groups.
MSA, muscle-strengthening activity; MVPA, moderate-to-vigorous physical activity; PA, physical activity.
