Study Notes
Overview of Maternal Nutrition
- Nutritional requirements vary throughout a woman's life, especially before, during pregnancy, and while breastfeeding.
- Highest risk for nutritional inadequacy occurs during pregnancy and lactation.
- Optimal nutrition prior to pregnancy helps build nutrient reserves, preparing the body for increased nutritional demands.
Importance of Adequate Maternal Nutrition
- Adequate maternal nutrition is crucial for the health of both the mother and developing infant, promoting safe deliveries and long-term health.
- Supports lactation by ensuring sufficient nutrient intake for breast milk production.
Physiology of Pregnancy
- Begins at conception, typically assessed as a 40-week duration from the last menstrual period.
- Significant physiological changes occur, increasing demands on maternal nutrient reserves.
- Maternal circulating nutrients support plasma volume expansion necessary for fetal development.
Normal Changes During Pregnancy
- Body water capacity expands from approximately 7 to 10 liters; high body water gain can lead to edema.
- Birthweight correlates strongly with plasma volume.
Maternal Nutrient Metabolism Changes
- Nutrient metabolism begins within weeks of conception to ensure fetal nutrient availability.
- Carbohydrate metabolism shifts; glucose serves as the fetus's primary fuel source, influenced by hormonal changes throughout pregnancy.
Effects of Pregnancy on Metabolism
- Diabetogenic effect arises due to increased maternal insulin resistance.
- Accelerates fat metabolism to primarily utilize stored fat for energy, sparing glucose for the fetus.
Protein and Fat Metabolism
- Increased protein and nitrogen requirements necessitate adequate maternal dietary intake.
- Enhanced fat mobilization occurs in the second half of pregnancy; blood lipid levels rise for hormone synthesis and fetal development.
Mineral Metabolism Changes
- Changes support plasma volume expansion and nutrient transfer to the fetus, with significant roles for calcium and sodium.
- Calcium is vital for bone formation; sodium accumulation is essential for fetal development.
Placental Functions
- The placenta is critical for hormone production, nutrient exchange, and waste removal, with a cellular structure separating maternal and fetal blood.
Fetal Nutritional Dynamics
- Fetal nutrient needs are prioritized last after maternal and placental requirements, making fetal health sensitive to maternal nutritional status.
Factors Influencing Maternal Nutrition
- Geographic location and socioeconomic status affect food accessibility and dietary choices.
- Social and cultural norms can limit women's decision-making regarding nutrition, impacting overall nutrient intake and health outcomes.
Maternal Nutrition in Ghana
- Poor maternal nutrition is linked to high child mortality rates in Ghana, highlighting its public health significance.
- Despite improvements, child mortality rates remain high compared to other African countries.
Pregnancy Weight Gain Recommendations
- Weight gain during pregnancy is critical and linked to the newborn's health, taking into account pre-pregnancy weight status and body mass index.
