This study sought to evaluate the associations between social determinants of health (SDOH) at the time of first pregnancy and subsequent cardiometabolic health, defined as the development of metabolic syndrome. nuMoM2b-HHS (Nulliparous Pregnancy Outcomes Study- Monitoring Mothers-to-Be-Heart Health Study) is an ongoing prospective cohort study. Eight academic medical centers enrolled and continue to follow participants. 4484 participants followed a mean of 3.2 years from the time of their first pregnancy. N/a. Unadjusted and adjusted Poisson regression models with robust standard errors were used to obtain relative risks and 95% confidence intervals estimating the risk of metabolic syndrome for each baseline SDOH. In secondary analyses we examined the associations between SDOH and incident hypertension, obesity, and diabetes mellitus. Metabolic syndrome developed in 13.6% of participants. Higher socioeconomic position at the time of pregnancy was associated with lower rates of metabolic syndrome [income > 200% poverty level aRR 0.55 (95% CI, 0.42–0.71), attainment of a bachelor's degree aRR 0.62 (0.46–0.84) or higher aRR 0.50 (0.35–0.71)], while being single [aRR 1.45 (95% CI, 1.18–1.77)] and having low health literacy were associated with a greater risk of metabolic syndrome [aRR 1.98 (95% CI, 1.28–3.07)]. Over a short interval following first pregnancy, participants accumulated high proportions of cardiovascular risk factors and metabolic syndrome, with some risk associated with SDOH. The impact of interventions addressing SDOH in pregnant people on cardiometabolic health should be tested as a means of reducing health inequities at the population level. Central illustration. Associations between social determinants of health at first pregnancy and future cardiometabolic health. Data shown are adjusted relative risks and associated 95% confidence intervals. Models are adjusted for age, self-reported race/ethnicity, body mass index, tobacco use, and physical activity at baseline. Bold type indicates p
