Table 4. Regression models predicting birth weights in offspring of female participants (n = 675).

	Model 1a	Model 2	p	Model 3	p	Model 4	p	Model 5	p
Mother’s birth weight (kg)		253 (53)	0.0001	286 (55)	0.0001	271 (58)	0.0001	−0.67 (1.46)	0.647
Mother’s gestational age at birth (weeks)				−24.9 (11.8)	0.035	−24.5 (11.8)	0.039	−24.2 (11.9)	0.042
Mother’s height (cm)						4.0 (4.9)	0.423	−14.3 (29.3)	0.625
Mother’s height–by-mother’s birth weight								0.006	0.520
Model adjusted R2	0.030	0.067		0.074		0.074		0.073

Values are β (SE).

^aBase model adjusts for mother’s age, first born, born early, born late, male baby, worked during pregnancy, prenatal care during pregnancy.
