Chronic Hypertension Is Contributing Substantially to Maternal Deaths

A new study has found that chronic hypertension could be a risk factor for maternal death among black women in particular. Researchers from Rutgers Robert Wood Johnson Medical School’s Department of Obstetrics, Gynecology, and Reproductive Sciences suggest that mortality rates among women with chronic hypertension have increased substantially.

For the study, researchers analyzed data from more than 155 million births and 3,287 hypertension-related maternal deaths among women aged 15 to 49 from 1979 to 2018 in the United States. The conclusion published in Hypertension showed a 15-fold increase in maternal mortality rates associated with chronic hypertension over the 40-year period.


Researchers note that hypertension-related deaths declined in the US over the last 40 years, but this decline was restricted to women who had pre-eclampsia/eclampsia as the cause. When the data on women with chronic hypertension is isolated, mortality rates increase substantially. Researchers define chronic hypertension as a pre-existing hypertensive condition or hypertension diagnosed within the first 20 weeks of pregnancy.

On average, mortality rates among women with chronic hypertension have risen about 9.2 percent per year over the last 40 years. This shows that chronic hypertension has really driven the maternal mortality trends over the past 40 years.

Age can be a factor in mortality linked to chronic hypertension, as the incidence among older women sharply increased, with the highest among women aged 45 – 49. Obesity was also found to be a factor in maternal mortality.

Researchers also noted a substantial race disparity in maternal mortality trends due to hypertensive conditions. Black women had a three- to four-fold increased risk of dying from a hypertension-related cause compared to white women in the US. Researchers believe this may be due to problems with access to care and higher risk factors in the group.


Strategies are needed to reduce the mortality rates among women with chronic hypertension. Researchers believe the key is focusing on improvements in advanced maternal age, obesity, and racial inequalities. The need to better identify and treat women with chronic hypertension and develop better interventions are needed, including blood pressure control and management of body mass index.

A Common Condition

Blood pressure is a condition that not only affects pregnant women, but nearly half of the adult population in the US have hypertension. The condition can lead to a host of health problems, so it is vital to take steps to help reduce blood pressure readings.

Health Blood Pressure Support is formulated to provide comprehensive support of healthy blood pressure and overall health. Using several ingredients, this formula has been shown in human clinical studies to help support healthy blood pressure, cholesterol levels, and overall cardiovascular health.

Sarah began her interest in nutritional healing at an early age. After going through health problems and becoming frustrated with the conventional ways doctors wanted to treat her illness (which were not working), she took it upon herself to find alternative treatments. This led her to revolutionize her own diet to help her get healthier and tackle her health problems. She began treating her illness by living a more balanced lifestyle through healthy food choices, exercise and other alternative medicine such as meditation. This total positive lifestyle change led her to earn a diploma in Nutritional Therapy from Health Sciences Academy in London, England. Today, Sarah enjoys helping others by teaching healthy lifestyle changes through her personal consultations and with her regular contributions to the Doctors Health Press. Also, passionate about following her dreams in life, Sarah moved to France and lived in Paris for over 5 years where she earned a certification in beadwork and embroidery from Lesage (an atelier owned by Chanel). She then went on to be a familiar face sitting front row and reporting from Paris Fashion Week. Sarah continues to practice some of the cultural ways of life she learned while in Europe. They enjoy their food, and take the time to relax and enjoy many of life’s little moments. These are life lessons she is glad to have brought back home with her.
