OVERVIEW

Masalah-masalah Kehamilan

INCREASED NUTRITIONAL RISK

Pregnant women who are:• Drug or alcohol abusers• Vegetarians• Smokers• Anorexic or bulimic, underweight, or obese

Pregnant women with:• Hyperemesis • Poor weight gain or weight loss • Dehydration, constipation• Pre-existing medical conditions

OBSTETRICAL HISTORY

Past medical history (wt gained in pregnancy)

Current dietary intake patterns and ETOH Vitamin, mineral and herbal intake PICA: dirt, starch, clay, ice, detergent Caffeine and other fluids Nausea, vomiting, and heartburn Constipation

OBSTETRICAL PHYSICAL EXAM

Low pre-pregnancy weight and low maternal weight gain are risk factors for: Intrauterine growth retardationLow birth weight baby Increased incidence of perinatal death

Need to asses:Pre-pregnancy weight (BMI)Current weight (BMI)Weight gain from previous visit

NAUSEA AND VOMITING Associated with increased levels of

HCG (Chronionic Gonadotropin)asal dari plasenta Peaks at 12 weeks gestation

Strategies for managing morning sickness: Eat small, low-fat meals and snacks Drink fluids between meals, avoid caffeine Reduce citrus, spearmint, peppermint Limit spicy and high-fat foods Avoid lying down after eating or drinking Take a walk after meals Wear loose-fitting clothes

CONSTIPATION Constipation during pregnancy is associated

with: increased progesterone levels and smooth-

muscle relaxation of the GI tract.

This results in GI discomfort, a bloated sensation, increased hemorrhoids, and decreased appetite.

Increase fluid and fiber intake to reduce constipation.

GENERAL OVERVIEW OF NINE MONTHS OF PREGNANCYFrom Conception to Birth

THE FIRST TRIMESTER

Lasts from conception to the twelfth week of pregnancy

3 periods during the first trimester: The Germinal Period

Fertilized egg travels and implants in wall of uterus Implantation occurs 10-14 days after conception

The Period of the Embryo Lasts from third through eighth week of pregnancy Major organs and anatomical structures begin to form

The Period of the Fetus Lasts from ninth week of pregnancy until birth All major organs continue rapid growth and become

interconnected

THE SECOND TRIMESTER

Fetus assumes distinct human appearance The nails harden and skin thickens, as well as

the eye lashes, eye brows, and scalp hair appear during fifth and sixth months

Fetus’s visual and auditory senses are functional

THE THIRD TRIMESTER

All organ systems mature rapidly Fetus prepares for birth Fetus reaches ‘age of viability’, the

point at which the fetus can survive outside of the uterus

Fetus shows better-organized gross motor activity, and sleepiness/ waking activity

Towards end of ninth month, fetus is positioned head-down with limbs curled up in ‘fetal position’

TERATOGENS

External agents such as viruses, drugs, chemicals and radiation that can harm a developing embryo or fetus.

Time when organ system or body part is at highest risk of effects from teratogens is known as ‘sensitive period’.

Effects of teratogens on a body part or organ system are worst during the period when that structure is forming and growing most rapidly.

TERATOGENS The same defect can be caused by

different teratogens. A variety of defects can be caused by

a single teratogen. The longer the exposure or the higher

the ‘dose’ of the teratogen, the more likely it is that serious harm will be done.

The long-term effects of a teratogen often depend on the quality of the postnatal environment.

RATE OF WEIGHT GAIN

Pattern of weight gain in pregnancy as important as total weight gain.

Deviations from expected patterns of weight gain are signals for intervention.

Pre-term birth doubles when 3rd trimester weight gain is low or inadequate.

Pregnancy is an anabolic state, resulting in increased energy (300 kcal/day) utk wanita umur 25-50

Select the orange to proceed.

GOOD SOURCES OF OMEGA-3 FATTY ACIDS

Fish oil capsules Certain fish such as salmon, trout, mackerel,

sardines, and fresh tuna Vegetable oils such as sunflower, rapeseed,

flaxseed, and walnut oils


VITAMIN AND MINERALREQUIREMENTS IN PREGNANCY

• Pregnant women are at increased risk for folic acid, iron, and calcium deficiencies.

• Recommendations are: Iron – indonesia 30-60 mg/hari Folate – indo 400 mg/hari Calcium -indo 1200mg/hari Magnesium - —indo 320 Vitamin C – indo 70 mg/day Iodine—indonesia 175mg/hari

CALCIUM AND VITAMIN D Calcium and

vitamin D are needed for strong bones and teeth

Vitamin D is needed for the formation of the fetal bones

Recommended 10 micrograms of Vitamin D per day


GOOD SOURCES OF CALCIUM AND VITAMIN D

Milk and other dairy products Eggs Meat Certain fish such as salmon, trout, mackerel,

sardines, and fresh tuna


CALCIUM REQUIREMENTS

DRI Calcium Recommendations 9 - 18 y/o: 1300 mg/day 19 - 50 y/o: 1000 mg/day (adults, pregnant and lactating) >51 y/o: 1200 mg/day Increased requirements during the third trimester Supplementation shown to reduce hypertension during

pregnancy

Dietary sources Milk, yogurt (8 oz), cheese (1 oz) ~ 300 mg calcium Orange juice- fortified (1 cup = 300 mg) Broccoli, kale (1 cup cooked = 90 mg) Bok choy, mustard green (1 cup cooked =180 mg) Tofu (made with calcium citrate- (½ cup =260 mg) Canned salmon (3 oz = 180 mg)

NEURAL TUBE DEFECTS (NTD) PREVENTION: ROLE OF FOLATE Folate deficiency is the most common deficiency during

pregnancy

Functions: Serves as a co-factor in one-carbon transfers, (nucleic acids

and amino acids) and therefore required during periods of rapid growth.

Increased maternal erythropoesis causes increased folate needs during second and third trimesters.

Role in Prevention: NTD are thought to result from a dietary deficiency of folate

and/or a genetic defect affecting folate metabolism.

During pregnancy, the neural tube is formed from the 18th to the

26th DAY of gestation.

NEURAL TUBE DEFECTS


FOLATE REQUIREMENTS IN PREGNANCY

Adequate folate is critical before and during the first 4 weeks of pregnancy.

Since 50% of pregnancies are unplanned and most women do not seek prenatal care until 8 weeks gestation, folate supplements prior to conception are critical to prevent NTD.

Folate Antagonists (taken during 2nd or 3rd trimester doubles fetal CV defects): Phenobarbiotic Phenytoin Primidone Carbamazepine Trimethoprin Triamterene

IRON IN PREGNANCY

Iron is an essential element in all cells of the body.

During pregnancy, maternal blood volume increases 20-30%.

Iron needs increase from 18 to 27 g/day during pregnancy.

Deficiency increases risk of maternal and infant death, preterm delivery, and low birth weight babies.

DIAGNOSIS OF IRON DEFICIENCY ANEMIA

The CDC reference criteria for anemia during pregnancy:

First trimester Hgb <11.0 g/dl or Hct <33%

Second trimester Hgb < 10.4 g/dl or Hct <32%

Third trimester Hgb <11.0 g/dl or Hct <33%

IRON DEFICIENCY ANEMIA Susceptible Populations:

Pregnant women who have not been taking iron supplements

Infants and childrenMenstruating femalesTeensLow income women

Etiology: Poor iron intake - only 25% of females 12 - 49 meet

needs Diet with low bioavailable iron

IRON DEFICIENCY ANEMIA

Weakness, fatigue, poor work performance, and changes in behavior.

Physical signs include pallor, fatigue, coldness and paresthesia of the extremities, greater susceptibility to infections.

Infants and young children with iron deficiency may have low IQ levels, poor cognitive and motor development, learning, and behavioral problems.

IRON TREATMENT RECOMMENDATIONS

Iron-rich foods: Meat, fish, poultry, eggs Organ meats Peas and beans Dried fruit Whole grain and enriched cereal

Therapeutic dose/supplements 30 mg TID but can be constipating IV iron, but may cause a reaction

VITAMIN A AND IODINE Vitamin A is needed in small(indo +300 mg/hari)

amounts to protect the fetus from immune system problems, blindness, infections, and death Can cause birth defects in high doses

Lack of iodine could contribute to stillbirth, birth defects, and decreased brain development

Iodine is important for brain development


NO ALCOHOL AND LIMITED CAFFEINE

Protect the infant from fetal alcohol syndrome and other birth defects Avoid alcohol, including all wines, beers, hard liquor,

and wine coolers High caffeine intake linked to low birth weight and

spontaneous fetal death Avoid food and beverages such as teas, coffee, colas,

energy drinks, and chocolate


FOOD BORNE ILLNESS

Raw and highly carnivorous fish should be avoided. Including: fresh tuna, shark, tilefish, swordfish, king mackerel

All dairy foods and juices should be pasteurized.

Food contaminated with heavy metals can have neurotoxic effects for the fetus. (Mercury) Minamata disaster

Listeria monocytogenes contamination in pregnancy develop into a serious blood borne, transplacental infection. Wash vegetables and fruits Cook meats Avoid processed, precooked meats (cold cuts) Avoid soft cheeses (brie, blue cheese, etc.)

EXERCISE DURING PREGNANCY

Benefits of exercise during pregnancy: Helps reduce backaches, constipation, bloating, and swelling May help prevent or treat gestational diabetes Increases energy, improves mood and sleep Improves your posture, promotes muscle tone, strength, and

endurance

Acceptable activities: Walking, dancing, biking Swimming, Yoga

Exercises to avoid: Downhill Skiing, Scuba Diving, Trampoline Contact Sports (Ice Hockey, Basketball, Amusement Slides) Hot tubs

Warning Signs to stop exercise: Vaginal bleeding, uterine contractions, decreased fetal movement,
