The association of hyperuricemia and immediate postpartum hypertension in women without a diagnosis of chronic hypertension

Our objective was to determine if elevated uric acid (UA) is associated with postpartum hypertension (PP HTN) in women without chronic hypertension. This is a secondary analysis of a randomized trial. We compared those with elevated UA to those with normal UA. Logistic regression was conducted to determine the association of elevated UA with PP HTN. Five hundred and fifty-six women met criteria. An UA level ≥ 5.2 mg/dL was associated with immediate PP HTN (adjusted odds ratio 2.44, 95% CI 1.63–3.64). The association was stronger among overweight and obese women. We conclude that hyperuricemia is associated with PP HTN, especially among obese women.
