Predictors of 18-Year Post Delivery Body Mass Index

Variable	18-Year Postdelivery BMI (N=298)
Variable	B	95% CI
Constant	5.437	[−4.284, 15.157]
Prepregnancy BMI	1.167^**	[1.003, 1.331]
Gestational weight gain	0.148^**	[0.100, 0.196]
Maternal age at conception	−0.250	[−0.711, 0.210]

R² (adjusted)	0.43
F	37.83^**

Note. BMI=body mass index; CI = confidence interval. Model 2 for 18-year postdelivery BMI had no significant interactions so testing for interactions was excluded from the table.
