Study Notes
Maternal Morbidity and Mortality
- Maternal morbidity and mortality are significant health concerns
- Anemia during pregnancy is a common concern
- Anemia is a reduction in red blood cell measurements (hemoglobin, hematocrit, or RBC count)
- Pregnant women are at higher risk due to increased blood volume needed to nourish the fetus
- Untreated anemia can be dangerous, impacting both the mother and baby
- Anemia during pregnancy is linked to low birth weight, premature birth, and maternal mortality
- Prevalence of anemia in reproductive-age females is estimated at 30%
- WHO estimates over 40% of pregnancies are complicated by anemia
- Variations in anemia's prevalence reflect socioeconomic status and nutritional deficiencies
- Anemia definition varies by trimester (e.g., first trimester hemoglobin <11.0 g/dL, second trimester hemoglobin <10.5 g/dL, third trimester hemoglobin <11.0 g/dL, postpartum hemoglobin <10.0 g/dL)
- Physiologic anemia of pregnancy, a dilutional type, is due to increased plasma volume exceeding RBC increase, typically peaking between 24-26 weeks.
- Iron deficiency is the most common pathologic cause of anemia in pregnancy (responsible for approximately 95% of cases)
- Many pregnant individuals have already have iron deficiency
- Factors contributing to iron deficiency include insufficient dietary iron, blood loss from prior pregnancies or menstruation, and short interpregnancy intervals
- Folate deficiency is another cause of anemia in pregnancy and a type of megaloblastic anemia and is often associated with diets low in animal proteins, leafy vegetables and legumes.
- Recommended daily folate intake is 400–800 mcg during pregnancy.
- Common risk factors for anemia during pregnancy include twin pregnancies, poor nutrition, smoking, high alcohol consumption, and multiple vitamin deficiencies
- Routine screening for anemia and iron deficiency is recommended in pregnancy
- Complications associated with anemia include placental abruption, preterm birth, severe postpartum hemorrhage, and increased risk of maternal mortality
- Urinary tract infections (UTIs) are common in pregnant women.
Urinary Tract Infections (UTIs)
- Asymptomatic bacteriuria (presence of significant bacteria in urine without symptoms) affects 2%–7% of pregnant women, typically occurring during early pregnancy
- Untreated asymptomatic bacteriuria increases the risk of symptomatic UTI from 20% to 35%
- Treatment of asymptomatic bacteriuria reduces that risk significantly to below 10%.
- Hormonal changes, enlarging uterus, changes in vaginal flora and immune system adjustments predispose pregnant women to UTIs.
- Routine screening for asymptomatic bacteriuria is done in most cases between 12–16 weeks of gestation
- Untreated asymptomatic bacteriuria is related to preterm birth, low birth weight, and preventable perinatal mortality.
Gestational Diabetes Mellitus (GDM)
- Gestational diabetes (GDM) is hyperglycemia developing during pregnancy, particularly the second or third trimester
- GDM is due to increasing insulin resistance during gestation
- GDM usually resolves after pregnancy, but women who had GDM have a higher risk of developing type 2 diabetes later in life
- Worldwide prevalence of GDM is estimated at 17%
- Variations in prevalence reflect population differences (e.g., maternal age, BMI, and screening/diagnostic criteria)
- GDM risk factors include prior GDM (40% risk of recurrence), family history of diabetes, pre-pregnancy BMI ≥30, medical conditions associated with diabetes development (e.g., PCOS), older maternal age (≥35), and prior delivery of an infant weighing ≥4000 g
- Complications of GDM for the mother include Cesarean section, polyhydramnios (excess amniotic fluid), pre-eclampsia, and type 2 diabetes development (50% risk within 5–10 years of delivery)
- GDM complications for the fetus include increased risk of macrosomia (oversized baby), shoulder dystocia, obesity, and other complications like autism spectrum disorders, cardiomyopathy, neonatal respiratory problems, including hypoglycemia, stillbirth, and medically-indicated preterm birth
Maternal Mortality
- Maternal mortality is the leading cause of death among reproductive age women in most developing countries
- In 2020, 287,000 women globally died during and after pregnancy or childbirth
- Maternal mortality risk factors include lack of adequate medical care, socioeconomic factors, and high total fertility rate
- Causes of maternal mortality include severe bleeding, infections, high blood pressure, delivery complications, and unsafe abortions accounting for nearly 75% of deaths
- Improving maternal health is a key priority for WHO and efforts include addressing inequalities in access to and quality of maternal and child health services, ensuring universal health coverage, and strengthening health systems.
- Postnatal care is essential but often neglected
- WHO recommends several stages of postnatal evaluation throughout the first 6 weeks after child birth.
- Poor postnatal care can lead to high maternal and infant mortality.
Postnatal Care
- Women and newborns need support and careful monitoring after birth
- Postnatal care is a critical but often overlooked component in preventing maternal and child mortality
- WHO recommends regular postpartum checkups (e.g., within 24 hours, 3 days, 7–14 days, and six weeks)
- Key aspects of postnatal care include observing physical status, advising and supporting on breast-feeding, providing emotional and psychological support, health education on weaning and food preparation, and advising on family planning.
