However, the relationship between these conditions is uncertain.

To reduce limitations of administrative coding for placenta accreta spectrum, the analysis was restricted to deliveries at &lt;37 weeks\u2019 gestation. Incidence rates and unadjusted incidence rate ratios were calculated, using gestational weeks to account for the person\u2010time\u2010at\u2010risk of developing hypertensive disorders of pregnancy.

A total of 0.7% of individuals had placenta accreta spectrum, and 29.8% had hypertensive disorders of pregnancy. The incidence of hypertensive disorders of pregnancy significantly differed between those with and without placenta accreta spectrum (11.5 vs. 20.6 cases per 1000 person\u2010gestational weeks) with an unadjusted incidence rate ratio of 0.56 (95% confidence interval [CI] 0.51\u20130.61).
