The United States is one of the countries with the highest rates of maternal mortality in the world, with significantly higher rates than other developed countries. Maternal mortality is defined as the death of women who are pregnant or recently gave birth. Many studies suggest that those deaths are preventable and result from a lack of quality care and unnecessary medical interventions. It is notable that there are specific populations, which I describe as “vulnerable,” that are at increased risk of maternal mortality, including women of color, women in poverty, and women with low socioeconomic statuses. The United States also has lower rates of midwife-assisted births than other developed countries, which suggests that there is an association between adverse birth outcomes, such as maternal mortality, and midwifery care. In my thesis, I investigate that association and answer the question: Do midwives lower rates of adverse birth outcomes in vulnerable populations? I describe the history of midwifery in the United States and analyze the factors that lead to lower adverse birth outcomes in midwife-attended births. I then suggest methods for integrating midwives into the United States healthcare system, which I suggest will lower rates of maternal mortality.
