CI, confidence interval; HDP, hypertensive disorders of pregnancy; HR, hazard ratio.
Prevalence defined as at least one maternal hospital encounter (with a qualifying diagnosis) in 12 weeks after delivery.
All comparisons between groups without versus with HDP had P < 0.001.
Adjusted for maternal age category, race/ethnicity, insurance status, prepregnancy obesity, chronic diabetes, gestational diabetes, mode of delivery, gestational age category, and birth outcome [term not small for gestational age (SGA), versus preterm or SGA, versus stillborn].
See Table 1 for the condition-specific diagnostic categories included in each major category. The most common conditions in each major category were hypertensive disorders and acute cardiovascular disease (hypertension-related); urinary tract infection and uncontrolled pain (childbirth-related); and nonspecific postpartum diagnosis and gallbladder disease/pancreatitis (other).
Ten most common condition-specific diagnostic categories, and hypertensive disorders. See Supplement 3, http://links.lww.com/HJH/B507 for less common diagnoses.
