Objectives
To assess the prevalence of high blood pressure amongst postpartum women in rural Tanzania, and to explore factors associated with hypertension prevalence, awareness of their own hypertension, treatment, and control.
Methods
We conducted a cross-sectional study of 1,849 women in Tanzania’s Pwani Region who delivered a child in the prior year. We measured blood pressure, administered a structured questionnaire, and assessed factors associated with hypertension (HTN) prevalence, women’s awareness of their own HTN, treatment, and control of HTN using bivariable and multivariable logistic regressions.
Findings
26.7% of women had high blood pressure and/or were taking antihypertensive medication. Women were on average 27.5 years old (range 15–54). Nearly all women (99.5%) reported contact with the health system during their pregnancy and delivery, with 97.0% reporting at least one antenatal care visit, 81.4% reporting facility delivery, and an overall average of 5.2 visits for their own care in the past year. Only 23.5% of those with HTN were aware of their diagnosis, 17.4% were taking medication, and only 10.5% had controlled blood pressure. In multivariable analysis, facility delivery, health insurance, and increased distance from a hospital were associated with increased likelihood of HTN awareness; facility delivery and hospital distance were associated with current hypertensive treatment; younger age and increased hospital distance were associated with control of HTN.
Conclusion
The prevalence of high blood pressure in this postpartum population was high, and despite frequent recent contacts with the health system, awareness, treatment and control of HTN were low. These findings highlight an important missed opportunity to improve women’s health during antenatal and postnatal care.
