Hypertensive disorders of pregnancy (HDP) are the leading cause of pregnancy-related mortality worldwide [1], [2]. HDPs are particularly common in sub-Saharan African countries such as Tanzania [3], [4]. For women with HDP in low-income countries, data are lacking to describe the persistence of hypertension beyond puerperium [5], [6]. Persistent postpartum hypertension is often missed as women transition from obstetric care to general primary care [7], [8], [9]. Most studies from Africa only report outcomes up to 6 weeks postpartum, the typical duration of postpartum follow-up [10], [11], [12].

We sought to determine the persistence of hypertension and its predictors among women delivering with HDP in Tanzania.
