Changes in self-reported moderate- to vigorous-intensity leisure-time physical activity by condition and time, M (95% CI) unless otherwise noted

Self-reported MVPA Exercise Nutrition Model 1a Condition × Time
Leisure-time MVPA (hours/week)b F=4.22 (p=0.015)
    Baseline 2.1 (1.5, 2.9) 1.8 (1.2, 2.4)
    12 weeks 3.1 (2.4, 3.8) 2.3 (1.7, 2.9)
    d (% change)c 0.45 (44.3) 0.13 (13.8) 0.34
    9 months 3.0 (2.3, 3.7) 2.7 (2.0, 3.3)
    d (% change)c 0.34 (33.0) 0.21 (21.8) 0.14
Leisure-time MVPA (% reporting ≥2 hours/week) F=4.50 (p=0.01)
    Baseline 25.5 (17.5, 35.7) 22.4 (15.2, 31.7)
    12 weeks 53.0 (40.5, 65.0) 25.0 (16.7, 35.6)
    d (% change)c 0.59 (107.4) 0.06 (11.6) 0.55
    9 months 39.0 (27.7, 51.7) 26.0 (17.3, 37.0)
    d (% change)c 0.29 (52.9) 0.08 (16.0) 0.22

Note: Boldface indicates significant difference from baseline value (p <0.05).

a

Adjusted for condition assignment, time, marital status, education, gender, and age.

b

For leisure-time MVPA, means in original units are reported, but statistical analyses, effect sizes, and percent change are based on square root transformation.

c

Effect size d and % change are calculated relative to baseline values and use adjusted means.

MVPA, moderate- to vigorous-intensity physical activity.
