History of infertility and pregnancy outcomes in Project Viva: a prospective study

Table 3 Unadjusted and adjusted β coefficients for systolic blood pressure in women with vs. without infertility, according to the use of MAR^a

	Unadjusted		Model 1		Model 2
Average SBP across pregnancy, mmHg^b	β	95% CI	β	95% CI	β	95% CI
Without history of infertility (n = 1646) [ref]	0.00		0.00		0.00
History of infertility without MAR (n = 250)	0.68	(−0.22, 1.57)	0.66	(−0.24, 1.56)	0.42	(−0.41, 1.25)
History of infertility with MAR (n = 127)	1.30	(0.09, 2.52)	1.46	(0.25, 2.67)	1.32	(0.21, 2.44)

Model 1: age at enrollment (18–29, 30–34, ≥35 years), race/ethnicity (white, Black, Asian, Hispanic, other), age at menarche (<12, 12–14, 15 years)
Model 2: model 1 + pre-pregnancy BMI (continuous) and pregnancy smoking status (former, smoker during pregnancy, never smoker)
MAR medically assisted reproduction, SBP systolic blood pressure
^aThe sample may not add 2201 due to missing outcome data
^bβ coefficient obtained from mixed regression models
