Maternal health refers to the health of women during pregnancy, childbirth, and the postnatal period. It encompasses everything from physical wellness and mental health to the social and economic conditions that shape whether a pregnancy is safe. While the term sounds straightforward, maternal health in practice spans a wide continuum of care, starting before conception and extending well beyond delivery.
The Continuum of Care
Maternal health isn’t limited to the nine months of pregnancy. It begins with preconception health, the set of interventions designed to identify and address risks before a woman becomes pregnant. This includes screening for chronic conditions like diabetes or thyroid disorders, ensuring adequate folic acid intake to prevent neural tube defects, reviewing medications that could harm a developing fetus, and addressing substance use or mental health concerns. The goal is to enter pregnancy in the best possible condition.
Once pregnancy begins, care follows a structured schedule. Prenatal visits typically occur once a month through week 28, twice a month from weeks 28 to 36, and weekly from week 36 until birth. These visits include blood type screening, tests for infections like hepatitis B and HIV, monitoring for anemia, and glucose challenge testing between weeks 26 and 28 to check for gestational diabetes. An ultrasound between weeks 18 and 20 evaluates fetal development. In the final weeks, screening for group B streptococcus (a bacteria that can cause serious newborn infections) happens around weeks 36 to 37.
The postpartum period, sometimes called the “fourth trimester,” extends care after delivery. Current guidelines recommend that all women have contact with their care provider within the first three weeks after birth, with a comprehensive visit no later than 12 weeks postpartum. Women who had high blood pressure during pregnancy should be seen even sooner, within 7 to 10 days.
Physical Risks During Pregnancy and Birth
The leading causes of maternal death worldwide are hemorrhage (severe bleeding), hypertensive disorders like preeclampsia, and indirect obstetric causes, meaning pre-existing conditions worsened by pregnancy. Infections, complications from abortion or miscarriage, and blood clots also contribute significantly. These causes rank consistently across most regions of the world, though the rates vary dramatically depending on access to care.
Many of these complications are preventable or treatable when caught early. Preeclampsia, for example, involves dangerously high blood pressure that can damage organs. Regular prenatal monitoring of blood pressure and urine (which can show signs of preeclampsia) helps detect it before it becomes life-threatening. Hemorrhage during or after delivery can often be managed in facilities equipped for emergency obstetric care, which is one reason where a woman gives birth matters enormously for her survival.
Mental Health Before, During, and After Pregnancy
Perinatal mental health is a core part of maternal health that has historically received less attention than physical complications. Depression related to pregnancy doesn’t always start after delivery. Research from one study found that 27% of women experienced depression onset before pregnancy, 33% during pregnancy, and 40% in the postpartum period. This means the majority of cases actually begin before the baby arrives.
Beyond depression, the perinatal period carries risk for anxiety disorders, post-traumatic stress disorder, and bipolar disorder. Screening tools exist for each of these: short questionnaires with as few as four questions for PTSD and up to 14 for bipolar disorder. The challenge is making sure screening actually happens at prenatal and postpartum visits. The fourth trimester brings a particular cluster of stressors, including sleep deprivation, fatigue, pain, breastfeeding difficulties, hormonal shifts, and loss of sexual desire, all of which can trigger or worsen mental health conditions.
How Social Conditions Shape Outcomes
A woman’s health during pregnancy depends heavily on factors outside the exam room. Education, income, and insurance status all correlate with maternal outcomes in ways that are well documented. Eight out of 12 studies in one systematic review found that lower education levels were associated with increased risk of maternal death and severe complications. Women with more education consistently had lower mortality rates, though the protective effect was stronger for vaginal deliveries than cesarean sections.
Insurance coverage tells a similar story. Out of 30 studies reviewed, 21 found that women with public insurance (like Medicaid) or no insurance faced higher risks of maternal death or severe complications compared to those with private insurance. These women also had higher rates of hospitalization, readmission, and emergency department visits within 90 days of delivery. Food insecurity likely plays a role too, though it hasn’t been as directly studied as insurance or education.
Racial Disparities in the United States
In the United States, maternal mortality varies starkly by race. In 2024, Black women died at a rate of 44.8 per 100,000 live births. That’s more than three times the rate for white women (14.2) and nearly four times the rate for Hispanic women (12.1). Asian women fell in between at 18.1 per 100,000. These gaps persist even when controlling for education and income, pointing to systemic factors in how care is delivered and experienced.
These numbers aren’t just statistics. They reflect differences in how symptoms are assessed, how pain is treated, how concerns are listened to, and how conditions are followed up on. Addressing racial disparities in maternal health requires changes at every level, from individual clinical encounters to hospital policies to the broader social conditions that put some women at higher risk before they ever walk into a clinic.
Global Progress and Goals
The United Nations set a specific target under its Sustainable Development Goals: reduce the global maternal mortality ratio to fewer than 70 deaths per 100,000 live births by 2030. Progress has been uneven. While some regions have dramatically reduced maternal deaths over the past three decades, others, particularly in sub-Saharan Africa and South Asia, still bear a disproportionate burden. The gap between high-income and low-income countries remains one of the starkest inequalities in global health.
Tracking progress relies on data from civil registration systems, population surveys, surveillance systems, and censuses, compiled by an inter-agency group that includes the WHO, UNICEF, and the World Bank. The most recent comprehensive estimates run through 2022. Reducing maternal mortality at the global level depends on the same fundamentals that matter locally: access to skilled birth attendants, emergency obstetric care, prenatal monitoring, and postpartum follow-up, layered on top of the social conditions that determine whether women can actually reach and afford that care.
