Table 2 Mean differences (95% confidence intervals) in rates of change in accelerometer-assessed sedentary time, light-intensity physical activity (LPA), moderate-to-vigorous intensity physical activity (MVPA), and overall physical activity in men and women, adjusted for all of the covariates of interest, baseline levels of the corresponding activity, season at baseline and follow-up, and wear time at baseline and follow-upa in men (n=528) and women (n=731)

  1. a Bolded values represent the estimated effects that have at least a small effect based on 95% confidence intervals. Season was coded as a continuous periodic variables at both baseline and follow-up (spring = sin (2 * π * day of year /365.25); winter = cos (2 *π* day of year/365.25)); No paid job versus paid job at present; married/living with partner versus single/widowed/separated/divorced; depressed versus not depressed (based on self-reported depression requiring treatment – yes versus no); car as primary mode of transport outside of work versus walking, public transport or cycling; current smoker versus former/never smoker; very good/excellent/good self-rated health versus fair/poor; urban versus rural home neighbourhood location
