Prevalence, risk factors and associated complications of postpartum hypertension in rural Haiti

The prevalence of hypertensive disorders during pregnancy is high in developing countries such as Haiti, however little is known about postpartum hypertension (PPHTN).

This is a prospective study done at Hospital Albert Schweitzer in rural Haiti among pregnant women age 18 or older who were admitted for labor. Blood pressures were collected before and after delivery and medical charts were reviewed to gather delivery characteristics and fetal/neonatal outcomes. Differences between groups are presented based on postpartum blood pressures (BP) as mild PPHTN (systolic BP≥140 or diastolic BP≥90) and severe PPHTN (systolic BP≥160 or diastolic BP≥110).

Of 175 women, the prevalence of PPHTN during the two-month study period was 57.1% (97/172) and included 56 parturients with mild and 41 with severe PPHTN. Severe PPHTN was associated with a higher proportion of complications including abruption (14.6%), fetal (14.6%) and neonatal death (7.3%). Thirty-nine (69.6%) patients with mild PPHTN and 9 (21.9%) patients with severe PPHTN did not receive any antihypertensive medications postpartum. Patients with severe PPHTN had prolonged hospitalization compared to the normal group (3.5 vs. 2.0days, p=0.0003). There was a strong correlation between antepartum and postpartum systolic and diastolic BP's (r=0.62 and 0.54, p<0.0001, respectively).

In this study, we identified a high prevalence of PPHTN in rural Haiti. Severe PPHTN was associated with adverse outcomes and treatment is not universal. This data is a starting point to develop region-specific protocols to treat and control PPHTN.
