^*The response rate for the 24-week survey was 84%.

^†MET minutes are a quantification of physical activity that reflect both intensity (in METs) and duration (in minutes) of activity.

^‡n=27 for this measure.

^§Higher scores signify more of that behavior.

^||n=29 for this measure.

^**Employer-sponsored personal health coaching, employer financial incentive for fitness club attendance, or commercial weight loss program.

With Bonferroni correction for three-way comparison, threshold for statistical significance = 0.0167.
