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.
