Table 4.

Results from adjusted regression models quantifying the association between treatment group and breastfeeding outcomes at the postpartum clinic visit.

	Model	Estimate	95% CI	P
Ever Breastfed (n = 1444)	Log-binomial	0.99 (aRR)	0.93 – 1.05	0.78
Current Breastfeeding at postpartum visit (n = 1124)	Log-binomial	1.01 (aRR)	0.94 – 1.10	0.75
Total Weeks Breastfeeding (n = 1108)	Cumulative Logit	0.87 (aOR)	0.68 – 1.12	0.30

CI, confidence interval; aRR, adjusted risk ratio; aOR, adjusted odds ratio.

All models compare active treatment group (receive antihypertensive medications with goal blood pressure of < 140/90 mm Hg) to control group (defer antihypertensive treatment until blood pressure ≥ 160/105 mm Hg) as a predictor for breastfeeding outcomes. All models adjusted for gestational age (at enrollment and delivery), body mass index, and discharged on antihypertensive medication.
