Four Way Decomposition Estimates for the Mediation of the Effect of Marriage on Change in MVPA from EAT-III to EAT-IV by Having a Child

	Proportion of Estimate [95% CI]
Controlled Direct Effect: Marriage --> MVPA	0.3 [−0.18 to 0.79]
Reference Interaction: (Marriage * Child) --> MVPA	0.27 [−0.08 to 0.63]
Mediated Interaction: (Marriage * Child) & (Marriage --> Child) --> MVPA	0.26 [−0.06 to 0.59]
Pure Indirect Effect: Marriage --> Child --> MVPA	0.16 [−0.17 to 0.48]
Proportion of Marriage - MVPA Effect Mediated by having a Child^a	0.42 [0.16 to 0.69]
Overall Proportion of MVPA Effect Attributable to Interaction between Marriage and having a Child^a	0.54 [−0.12 to 1.2]
Overall Proportion of Marriage - MVPA Effect Eliminated if participant does not also have a Child	0.7 [0.21 to 1.18]

Proportion mediated and proportion attributed to interaction can add to more than 100% because there is a proportion that is due to both mediation and interaction
