Study Notes
Preconception Health Care
- Preconception period is the time before a woman becomes pregnant and a man becomes a father
- Healthy lifestyle choices can improve fertility and likelihood of having a normal pregnancy and healthy baby
- Men's lifestyle choices can affect fertility, such as obesity leading to erectile dysfunction and sperm defects
- Both women and men should:
- Consume a nutritionally adequate diet
- Achieve and maintain a healthy body mass index (BMI)
- Avoid harmful drugs
- Exercise regularly
The Prenatal Period
- Prenatal period (gestation) is from conception to birth, about 38-42 weeks
- First 2 weeks: fertilized egg divides and forms a mass of cells that enters the uterus
- 2-8 weeks: mass of cells develops into an embryo, forming organs
- After 8 weeks: developing human being is referred to as a fetus
- Prenatal period divided into three stages or trimesters
Fetal Development and Risk
- First trimester: embryo/fetus develops most organs, critical stage in human development
- Second trimester: fetus grows and matures, begins to look like a human infant
- Third trimester: fetus nearly doubles in length and multiplies its weight by three to four times
- By full-term: fetus weighs about 6-8 pounds and is 19-21 inches long
Nutrition-Related Signs of Pregnancy
- Breast changes: hormones signal breasts to increase in size, preparing for lactation
- Morning sickness: nausea and vomiting, possibly due to hormonal changes
- Fatigue: physiological anemia, a normal response to pregnancy
- Digestive tract discomforts: constipation, heartburn, and edema due to hormonal changes
Pregnancy: General Dietary Recommendations
- Women of childbearing age should analyze their diets and correct any marginal or deficient intakes
- Pregnant women should follow a diet that meets their own and their offspring's nutritional needs
- Energy needs increase in the second and third trimesters
- Folate and iron needs are 50% higher than those of nonpregnant women### Nutrition During Pregnancy
- A sample daily meal plan for pregnant women includes:
- Breakfast: oatmeal with milk and raisins, orange juice
- Mid-morning Snack: orange juice, graham cracker, peanut butter
- Lunch: cheese sandwich, apple slices, fat-free milk, orange sherbet
- Mid-afternoon Snack: English muffin, margarine, jelly, fat-free milk
- Dinner: broiled salmon, mixed salad greens, Italian dressing, enriched white rice, steamed broccoli
- Evening Snack: frozen yogurt
- Fish and shellfish are excellent sources of minerals, omega-3 fatty acids, and high-quality protein, but pregnant women should avoid eating swordfish, shark, king mackerel, tilefish, marlin, orange roughy, and bigeye tuna due to high levels of methylmercury.
Cravings and Pica
- Cravings are common during pregnancy and may be responses to hormonal changes or emotional state.
- Pica, the practice of eating nonfood items, may be linked to iron and zinc deficiency, and pregnant women should refrain from practicing pica, especially eating clay or soil.
Weight Gain During Pregnancy
- Nearly all pregnant women experience weight gain, and gaining an appropriate amount of weight is crucial during pregnancy.
- Recommended weight gain during pregnancy depends on prepregnancy weight:
- Underweight: 28-40 pounds
- Healthy weight: 25-35 pounds
- Overweight: 15-25 pounds
- Obese: 11-20 pounds
- Excessive weight gain during pregnancy is associated with retaining extra pounds after birth, giving birth to high-birth-weight babies, and increased risk of obesity, diabetes, and hypertension in the baby.
- Underweight pregnant women should try to reach healthy weights by the end of the first trimester and then meet recommended weight-gain goals.
Accounting for Weight Gain
- Much of the weight gained during pregnancy is not body fat:
- Fetus: 7.5 pounds
- Placenta and amniotic fluid: 3.5 pounds
- Maternal weight gain: 11 pounds (blood, breasts, uterus, fat, protein, and retained fluid)
Rate of Weight Gain
- The rate of weight gain is important, as well as the amount of weight gained.
- Healthy women typically gain 3-4 pounds per month during the second and third trimesters.
Importance of Prenatal Care
- Prenatal care is specialized to meet the health care needs of pregnant women.
- Routine prenatal health care includes measuring and monitoring weight, blood pressure, blood glucose level, and uterine growth.
- Prenatal care helps diagnose and treat health problems early, and advises pregnant women on lifestyle choices.
Gestational Diabetes and Hypertension
- Gestational diabetes can be detected during routine prenatal care and is associated with giving birth to high-birth-weight babies.
- Gestational hypertension is a common condition that can develop after the 20th week of pregnancy and may lead to preeclampsia.
- Preeclampsia is characterized by sudden weight gain, high blood pressure, edema, headache, vision problems, and protein in urine.
Drug Use and Physical Activity
- Exposure to alcohol and tobacco is harmful to the embryo/fetus.
- Pregnant women should avoid drinking concentrated sources of caffeine and limit their caffeine consumption to 200 mg/day.
- The use of illegal drugs, herbal supplements, and medications during pregnancy can harm the embryo/fetus.
- Physical activity during pregnancy can have many benefits, including enhanced muscle tone and strength, reduced edema, and improved mood and sleep.
