  1. aA valid assessment occasion was defined as having all three days of pedometer data.
  2. Note: Paired t-tests were performed for participants who had two valid assessment occasions. Repeated measures ANOVA were performed for participants with three valid assessment occasions. JHS: Jackson Heart Study. ICC: Intraclass correlation coefficient. BMI = Body mass index.
