We explored associations between SDOH (race-ethnicity, nativity, insurance, nutrition program enrollment, education, and parity) and time to first follow-up test\/rate of A1C testing using Cox proportional hazards and Poisson regression, respectively. We constructed models that were unadjusted, mutually adjusted, and further adjusted for clinical characteristics (body mass index, gestational diabetes mellitus, and age).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Few women received all biannual recommended follow-up tests over the study period (13.0%). Non-Hispanic Black women were more likely to receive their first follow-up test later (adjusted HR (aHR): 0.90, 95%\u2009CI 0.80 to 1.00) and had a lower rate of testing over 3 years (adjusted rate ratio (aRR): 0.92, 95%\u2009CI 0.84 to 0.99) compared with non-Hispanic White women. Women insured by Medicaid at delivery experienced a higher hazard of an earlier first follow-up A1C test (aHR: 1.14, 95%\u2009CI 1.06 to 1.22) and higher rates of testing (aRR: 1.09, 95%\u2009CI 1.03 to 1.15) than those with private or other insurance. Women with more children experienced lower rates of testing and a longer time to first A1C test compared with those with no prior children.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Few women with postpartum-onset diabetes met A1C monitoring guidelines, suggesting a need to improve routine diabetes monitoring, particularly among Black women.
