Outcomes
The primary outcome was the change in total weekly energy expenditure at 3 months compared with the baseline, measured using an accelerometer, in MET-min. Secondary outcomes for objective measures were changes at 3 and 12 months compared with baseline for accelerometer-recorded step count and time spent performing light, moderate and vigorous physical activity, weight, waist circumference, and blood pressure.Secondary outcomes for self-reported measures were changes at 3 and 12 months compared with baseline for weekly physical activity level in MET-min calculated using IPAQ and quality of life measured using the SF-36 questionnaire, and perceived barriers to physical activity at 3 and 12 months assessed using the DPAQ.
