Study Notes

Nutrition During Pregnancy (Part 2)

General Outcome: Be familiar with physiological changes during pregnancy and how these changes affect nutritional needs.
Specific Outcomes:
- Describe physiological changes in pregnancy.
- Identify recommended weight gain ranges for different pre-pregnancy BMI categories (underweight, normal weight, overweight, obese).
- Identify relationships between nutritional status during pregnancy and long-term health outcomes in offspring.

Pregnancy Weight Gain

Weight gain during pregnancy indicates plasma volume expansion, positive calorie balance, and dietary adequacy.
Adequate weight gain improves newborn weight and health.
Women should not diet during pregnancy, as the fetus may not receive critical nutrients.
Insufficient weight gain can lead to premature birth and low birth weight infants, increasing risk for heart disease, diabetes, hypertension, and other chronic diseases later in life.

Pregnancy Weight Gain Recommendations

Pre-pregnancy weight status affects the relationship between weight gain and birthweight.
Women with higher weights before pregnancy need lower weight gains to produce healthy-sized infants.
Underweight women need to gain more weight in pregnancy.
Overweight/obese women need to gain less weight in pregnancy, using their energy stores to support fetal growth.

Recommended Weight Gains

Pre-pregnancy BMI categories and the corresponding recommended weight gain by full-term.
Weight gain for twin pregnancies is higher, from 11.4–24.5 kg.
Exceeding recommended ranges can lead to large for gestational age newborns, cesarean deliveries, and higher postpartum weight retention.
Restricting weight gain below recommended ranges is not advisable.
Uncontrolled weight gain could increase risk of pregnancy-related hypertension.

Rate of Pregnancy Weight Gain

Low rates of gain in the first half of pregnancy might lead to slow fetal growth and low birth weight.
Weight gain in the third trimester that is higher than 0.7 kg /week may lead to increased postpartum weight retention.
Weight gain generally increases around mid-pregnancy for optimal fetal growth.

Composition of Weight Gain in Pregnancy

Fetus accounts for only 50% of total weight gained during pregnancy.
Most weight is from increased weight of maternal tissues (e.g., placenta, uterus, amniotic fluid, breasts, blood, and fat stores)

Body Fat Changes

Pregnant women increase body fat to meet their own and the fetus's energy needs, as well as for lactation.
Body fat storage increases most between 10 and 20 weeks of pregnancy and then can decrease before the end of pregnancy.
Only a small amount (0.5 kg) of the stored fat is deposited in the fetus.

Postpartum Weight Retention

Average weight retained by women 1 year after delivery has increased from around 1 kg in the past, to higher weight ranges currently.
Women tend to lose around 6.4 kg in the first 6 weeks after delivery.
Weight loss rate slows after 6 weeks.
Weight loss is often more difficult for those who gained greater than 20 kg during pregnancy.
Overweight/obese women are more likely to gain weight between pregnancies.

Prevention of Excessive Body Weight After Delivery

Appropriate weight loss of 0.5 to 1 kg per month through diet and exercise is recommended.
Exclusive breastfeeding can facilitate postpartum weight loss.

Energy & Nutrient Needs During Pregnancy

All nutrient requirements increase during pregnancy, requiring attention to macronutrients, micronutrients, and fluids.

Energy Requirements During Pregnancy

Energy requirements increase primarily due to protein synthesis, fat synthesis, and expanded metabolic activity in the body's tissues, especially in the mother.
The fetus accounts for half of the increased energy needs during pregnancy, but the exact energy requirements changes over time.
Calorie intake adequacy is assessed by pregnancy weight gain.

Recommendations of additional energy needs for pregnant women in Malaysia

Additional energy needs in pregnancy increase over the three trimesters, varying by age.

Carbohydrate Requirements During Pregnancy

Glucose is a preferred fuel for early fetal development.
Carbohydrate metabolism changes, with increased insulin production and conversion of glucose to glycogen and fat in early pregnancy and increased reliance on fats to maintain glucose supply for the late pregnancy /developing fetus).
Women should consume at least 175 g of carbohydrates to ensure glucose for fetal brain development.
Healthy carbohydrate sources like vegetables, fruits, and whole grains can support pregnancy weight management and provide nutrients like fiber and antioxidants.
Artificial sweeteners and alcohol during pregnancy can have negative effects on the developing fetus.

Protein Requirements During Pregnancy

Protein requirements increase due to protein tissue accretion in the mother and fetus.
Protein is used less for energy generation during pregnancy.
Additional protein intake is needed to support the growing fetus.
Protein supplements are not beneficial for well-nourished women.

Fat Requirements During Pregnancy

Fats are crucial for fetal growth and development, acting as a source of energy, fat-soluble vitamins, and essential fatty acids.
Important omega-3 fatty acids in the fetus include linoleic and alpha-linolenic acids.
DHA is an important structural component of fetal nervous system, and is accumulated during pregnancy, and first year of life.

Micronutrients in Pregnancy

Essential during pregnancy.
Requirements increase due to placental and fetal growth, expansion of maternal tissues, plasma volume, and increased nutrient needs for tissue maintenance.
Example micronutrients include folate, iron, choline, water, sodium, iodine, calcium, vitamin A, and vitamin D.

Folate

Critical for DNA replication, gene expression and amino acid metabolism.
Critical role in the first 28 days of neural tube development.
Deficiency can cause neural tube defects.
Insufficient folate may cause anemia.
Good sources: bananas, avocados, orange juice, and leafy green vegetables.
Folic acid in supplements is typically more readily absorbed by the body than folate in food.

Choline

Essential nutrient for pregnant mothers.
Water-soluble compound, neither a vitamin nor a mineral.
Critical for synthesis of phospholipids in cell membranes.

Vitamin A

Involved in cellular differentiation.
Insufficient levels can affect fetal development.
Excessive intake (above 10,000 IU/day) can cause fetal birth defects.
Most supplements contain beta-carotene, a precursor to Vitamin A.

Vitamin D

The body produces it when exposed to UV rays.
Essential for fetal growth.
Supports calcium deposition in fetal bones, affecting tooth and enamel formation.
Obese and vegan women may have higher risk of low vitamin D levels.

Calcium

Important for fetal skeletal mineralization and maternal bone health.
Approximately 30 grams of calcium is transferred from the mother to the fetus during pregnancy.
Peak calcium demand by fetus is in third trimester.

Iron

Essential for delivering oxygen to the growing fetus and increasing maternal red cell mass during pregnancy.
Sources include meat, fish, poultry, and iron-fortified food.
Iron deficiency marked by reduced iron stores leads to signs such as fatigue and irritability.
Iron-deficiency anemia may lead to preterm delivery and low-birth-weight infants.

Iodine

Crucial for thyroid function and fetal brain development.
Iodine deficiency during pregnancy can lead to hypothyroidism in the offspring.
Sources include fish, shellfish, seaweed.

Sodium

Important for maintaining the body's water balance.
The body requires more sodium during pregnancy.

Water

Increased fluid intake is required for increased blood volume, regulating body temperature, producing amniotic fluid, and preventing issues like urinary tract infections and constipation.
Pregnant women should drink 8-12 glasses of water a day.

Potential problems that can frequently arise, such as nausea, vomiting, heartburn, constipation, cravings, aversions, edema, leg cramps, gestational diabetes, and pregnancy-induced hypertension.

Nausea & Vomiting

Occurs throughout pregnancy and may be related to increased hormones.
Symptom management includes: avoiding trigger foods, frequent smaller meals, avoiding smells, and selecting foods tolerated well.

Heartburn

Symptoms may be present throughout pregnancy, and related to changes in esophageal sphincter activity/relaxation, hormone changes, and uterine enlargement.
Managing heartburn includes: eating frequent small meals, avoiding trigger foods, not lying down after a meal, and avoiding smoking.

Constipation

Hormonal changes in pregnancy may affect gastrointestinal muscle function leading to constipation.
Managing constipation is important for avoiding problems such as hemorrhoids.
Treatment would include dietary fiber, plenty of fluid intake, and exercise.

Cravings & Aversions

Changes in taste and smell during pregnancy.
Can potentially be related to deficiencies but in some cases, no clear cause is found.

Edema & Leg Cramps

Mild, physiological edema in third trimester related to uterus pressure on vena cava affecting blood flow to the heart.
Leg cramps can be caused by pregnancy and lactation, potentially magnesium deficiency.

Gestational Diabetes

Insufficient insulin production or insulin resistance raise blood glucose levels during pregnancy.
Resolved after delivery.
Concerns for both mother and offspring, leading to potential complications.

Pregnancy-Induced Hypertension

Includes gestational hypertension, preeclampsia, and eclampsia.
Potential for grand mal seizures, dizziness, headaches, and other complications related to high maternal blood pressure during pregnancy.
High blood pressure during pregnancy can damage vital organs in both mother and fetus.

Effects of Nutritional Status & Lifestyle on Pregnancy Outcome

Various factors influence pregnancy outcomes, including obesity, multifetal pregnancies, adolescence, HIV, alcohol consumption, vegetarianism, dieting, caffeine consumption, exercise, smoking, illegal drugs, and food safety. Each has a range of effects on both maternal and fetal health.
Detailed data for each factor influencing pregnancy outcome is available.
