Decomposition Model of Life Events and MVPA on 24-Month Weight (in kilograms)
| β (95% CI) | P | |
|---|---|---|
| Adjusted effects of life events with 24-moa PA | ||
| Total effect | 1.63 (0.30 to 2.96) | .02 |
| CDE | 2.31 (0.29 to 4.33) | .03 |
| INTref | −0.84 (−2.31 to 0.64) | .26 |
| INTmed | −0.24 (−0.72 to 0.25) | .34 |
| PIE | 0.39 (−0.17 to 0.95) | .17 |
| Percent mediation | 9% (−7% to 26%) | .28 |
| Percent interaction | −66% (−199% to 57%) | .31 |
Abbreviations: CDE, controlled direct effect; CI, confidence interval; INTmed, mediated interaction; INTref, reference interaction; MVPA, moderate to vigorous physical activity; PIE, pure indirect effect.

Adjustment variables include age, gender, race, education level, marital status, baseline and 12-month weight, baseline physical activity, 12-month calorie intake, life-event frequency during active weight loss, and randomization arm.
