N = 338. B = unstandardized parameter estimate, β = standardized parameter estimate. POMP = Proportion of maximum possible score in the endogenous variables per unit change in the exogenous variable. Treat (intervention) was an exogenous variable (a predictor or an independent variable). FAT (high fat intake) and FAST (fast food intake) were endogenous variables (outcome or dependent variables). STRESS (perceived stress) was a mediator (an endogenous variable). The analysis controlled for education, employment status, age, and postpartum status.
