Accepting the importance of fetal programming places responsibility on the mother-to-be to do all she can to insure her body provides nutrients and oxygen to her growing infant while avoiding possible risks and toxins. At the same time, genetic and environmental factors contribute greatly to the potential for some disorders and problems that arise. Thus, we must be careful in assigning guidelines for acceptable behavior or blame for poor outcomes to pregnant women.

On the one hand, we can all see the negative consequences of something like fetal alcohol syndrome…clearly the result of maternal behavior. Is a pregnant woman whose baby has been damaged in this way guilty of abuse?

But, what if a mother is obese, eats poorly and ends up with an infant with a disturbed metabolism. Is this abuse? What if the mother has an infection that results in cerebral palsy? Or what if she lives near a highway and involuntarily inhales fumes that negatively affect the placenta?

How do you get a healthy baby? Of course, there are no guarantees. There remain many unknown factors that can affect the course and outcome of a pregnancy. Some factors we are aware of, such as avoiding certain fumes or chemicals.  There are some behaviors we know can maximize the potential for a good outcome, such as eating adequate protein, aerobic conditioning and strength training. [Note for new readers…lots of these factors have been covered in our previous posts.]

But, what about all the things we don’t know about?

If these goats eat the wrong grass, will they go into labor?

Here is a cautionary tale:  There is a species of goat that, if they eat a certain type of skunk grass on day 14 (and only day 14) of pregnancy, will not go into labor. Why? Plant toxins in this grass interfere with the development of a small portion of fetal brain, the paraventricular nucleus. This nucleus is involved in the signaling cycle of labor. Without it, the mother will not go into labor!

What are the take-home messages here?

• Probably no one is ever a perfect fetus…too many possible threats.
• There are some threats we can avoid…being lazy, over-eating, smoking.
• There are some threats we cannot avoid, so we do the best we can.

Do the best you can by your baby…aerobic fitness, good nourishment, sleep, good hygiene and de-stressing your life.

With the recent emphasis on the importance of movement in the fight against childhood obesity, there is recognition that beneficial fetal programming through maternal exercise can make a big contribution to this effort. A combination of proper maternal nutrition and maternal fitness may well prove to be most efficient and potentially effective way to help children develop an appetite for motion!

One factor in this is the finding that regular, moderate-intensity exercise helps prevent obesity in the newborn: http://www.nlm.nih.gov/medlineplus/news/fullstory_97212.htmlt. This, may in turn, help prevent childhood obesity.

Recess for everyone!!!

1. Women who return to vigorous (vigorous, as in jogging or aerobic dance) prior to six weeks postpartum…

• have less weight to lose
• experience a more joyful state of mind
• do better on the Lederman Maternal Adaptation scales (how well they adapt to motherhood)

…than women who are sedentary during this period (Sampselle, 1999…this is not new information)

2. Postpartum obesity is a dangerous short and long term health risk (Leddy, 2008).

Who should exercise and when, following birth?

Day 1: If you have a vaginal birth, begin your “body scan” the first chance you get. Within the first day, the first chance you get to focus on yourself, take a mental trip through your body. See if you can squeeze the kegel muscles. Try exhaling and sucking in your deep abdominal muscles. Note if your shoulders need to relax. Take some deep breathes and begin to help your body recover.

If you had a cesarean: Wait a few days to 2 weeks at most to work on this.

After that: As soon as you can, get up and walk around. Start walking in 5 or 10 minute strolls several times a day (ask someone to hold or watch baby so you can allow your body to recover a non-pregnant upright). If you had a cesarean, hold a pillow to your abdomen until you have control of your abdominal muscles and stand tall.

How can you get more information on this?

Go to our website:

http://dancingthrupregnancy.com/take-a-class/postpartum-exercise/

Find a class. If you had a typical birth and your baby has been slowly and safely exposed to new people, by four to six weeks you and baby should be ready for a structured activity session that includes baby. It will also provide focus and adult interaction during the week.

How do you know if you did too much?

Your lochia, or the bleeding/discharge from the placental site, will increase if you have been too vigorous. If you are healthy and have no anemia issues, your lochia will likely cease by three to four weeks, six at most.

What are safety issues?

Don’t exercise if you have a fever, a warm red spot on your leg that may be painful (or not), or sore nipples that need attention. Call your care provider. If you or your baby are sick, it is best not to go into a group setting. If your baby is not well or just doesn’t seem right, call your pediatrician.

The most important reason to join a mom-baby fitness program may be that it will help keep you sane.

Here is the link to the Guidelines:

IOM Pregnancy Weight Gain Guidelines

Fresh fruit = vitamins & minerals!!

Question:

How many extra calories do you need in each trimester to offset the metabolic cost of pregnancy?

Answer:

First trimester — 0; Second trimester — 300; Third trimester — 500 (source: Institute of Medicine).

Keep in mind that you may also need calories for any fitness program you are doing. If you are continuing a program, the only change is due to the pregnancy.

If you begin or increase your activity, you need to take that into account. One yoga class = 100 — 150 calories. One aerobics class = 200–400 calories. Walk one mile = 100 calories.

1 slice whole grain bread = 50–100 calories

Be sure you read food labels so that you can balance your food intake and your calorie output. A small woman (under 5’3″ & 130 lbs.) probably needs about 1200 calories per day as a base. A medium sized woman needs about 1400, and a large woman (over 5’9″ & 160 lbs.) probably needs 1600 to 1800 calories. Add your activity and pregnancy needs to your base amount.

Question:

What foods are necessary for a healthy pregnancy?

Answer, part A:

PROTEIN. Lean proteins like turkey and those with omega 3 fats like ocean fish and eggs.…yes! EGGS!

Turkey is a good protein

Ocean fish 1 or 2 times/wk = good protein & omega 3 fat

Eggs are a perfect pregnancy food!

70–90 grams of protein are necessary each day, along with  adequate water.  These are needed to make an extra 40% blood volume required to support the placenta.

Answer, part B:

WATER. Two (2) quarts of water…more if you are very active…are needed to make extra blood and to prevent dehydration.

Question: What else?

Fresh vegetables also provide fiber

Answer: CARBS. Fresh, colorful fruits & veggies provide necessary vitamins and minerals, as well as fiber. Eat 5 servings a day from all the colors:  yellow, orange, red, purple and green, and you will get live vitamins all day long that help your baby develop properly! Fruits, vegetables and whole grains are low glycemic index carbohydrates — the good ones!

Dairy provides calcium

Question:

Do I need dairy products and red meat? Can I get the needed minerals in other ways?

Answer:

Calcium is needed in adequate amounts for bones and teeth. It is most easily obtained by drinking milk or eating cheese, yogurt or cottage cheese. Soy, dark green leafy vegetables and calcium fortified juice are alternatives.

Iron is necessary for red blood cells to take up oxygen. It is found in high amounts in beef,  and lesser amounts in raisins, spinach, and prune juice. Prenatal vitamins are your insurance against deficiencies of these essential minerals.

Question:

Anything else that’s essential?

Answer:

Yes! Healthy FAT!!

Avocado is an excellent source of omega 6 fat

In addition to omega 3 fats found in fish, walnuts and flax seeds, you need also need omega 6 fats, which are found in avocados, olive oil and other vegetable oils. Healthy fats help balance cardiovascular constriction and dilation, reducing the risk for hypertension.

Last Question:

What is a healthy weight gain?

Answer:

In 2009, the National Academy of Sciences revised its recommendations. It now bases desirable weight gain on pre-pregnancy BMI (Body Mass Index…google this!).

BMI less than 18.5 (low) — 28 to 40 lbs.; BMI between 18.5–24.9 (normal) — 25 to 35 lbs.; BMI 25.0 to 29.9 (high) — 15 to 25 lbs.; obese women (BMI over 30.0) — 11 to 20 lbs.

Coming Next: Avoiding Risks.

So, what is safe? Well, first, unless you have a very few conditions that your health care provider considers unsafe, every woman — fit, currently sedentary, young or a little older — can exercise safely in pregnancy. How much of what kind depends on your fitness level and exercise history. Get medical screening first.

If you are fit, you can do vigorous exercise

If you are fit, you just need to learn how to modify some movements to accommodate your biomechanics. As your body changes, stress on the joints and tissues means a little less jumping or ballistic motion will be more comfortable and safer. If you are fit, you can continue with vigorous exercise and it will be of benefit to you and your baby.

If you are not so fit or are sedentary, find a certified pre/postnatal instructor and join a group where you will have fun, get some guidance and be monitored for safety. How do you find such a person? Try our Find A Class or Trainer page.

What is effective? Don’t spend your time on things that may be nice to do but don’t help you focus and prepare for birth, relieve discomforts or have the stamina for birth and parenting. There is substantial scientific evidence and information from large surveys that these things are helpful.

Cardiovascular or aerobic activity is the most important activity you can do. Already fit? Keep working out; join a class if you want support or new friends. If you are sedentary or somewhat active, you can improve your fitness by doing at least 20 — 30 minutes of aerobic activity 3 times a week. Work at a moderate pace — somewhat hard to hard — so that you can talk, but not sing an aria! If you are more than 26 weeks and have not been doing cardio, you can walk at a comfortable pace. Aerobics is key because it gives you endurance to tolerate labor and promotes recovery.

Strength and flexibility exercises that do not hurt and are done correctly are also safe. There are some special pregnancy exercises that actually help you prepare for birth. Essential exercises that aid your comfort, alignment and birth preparation include:

• Kegels (squeezing and relaxing pelvic floor muscles) — squeezing strengthens them and thus supports the contents of the abdomen, and learning to release these muscles is necessary for pushing and birth.

• Abdominal hiss/compress and C-Curve® - contracting the transverse abdominal muscles reduces low back discomfort and strengthens the muscle used to push and later to recover abdominal integrity after birth.

Squatting

• Squatting — getting into this position strengthens the entire leg in a deeply flexed position; start seated and use arms for support, stability and safety. Leg strength improves mobility and comfort in pregnancy and postpartum; plus, deep flexion is a component of pushing in almost all positions.

• Strengthening for biomechanical safety — strengthening some parts of the body helps prevent injury to bone surfaces, nerves and blood vessels within joints re-aligned in pregnancy. This can be done using resistance repetitions (weights, bands, calisthentics or pilates) or isometrics (yoga or ballet). A responsible class will focus on upper back (rowing), push-ups, abdominals, gluteals, hamstrings, and muscles of the lower leg.

• Stretching of areas that tend to get tight — relieving some discomforts through flexibility helps you maintain a full range of motion. Static stretches, used in combination with strength exercises or following aerobics, is most effective. Stretching prior to exercise tends to produce more injuries than not stretching. Areas needing stretching include the chest, low back, hamstrings and hip flexors (psoas).

Mind/Body skills are very important. There are two activities that exercisers constantly tell us are a big help in pregnancy, birth and parenting.

• Centering employs a balanced or neutral posture, deep breathing and mindfulness to help you work in a relaxed way. Athletes and dancers call this “the zone.” Starting your workout in association with your body establishes economy of motion, something very useful in birth and parenting, and reduces risk of injury.

• Relaxation is another key activity; it relieves stress, promotes labor in the early stages and helps you enter the zone!

Remember: Birth is a Motor Skill™

Behavior Affects Pregnancy Outcome

Physical exertion (we call it “exercise” nowadays) is a normal state for healthy humans. Only in the last century has the desire to rest or the need to store extra calories as fat become more possible to achieve than our need to move about to survive.

Pregnancy is a state in which both of these factors (resting and storing calories) are enhanced through organic changes in body chemistry, adaptations that favor fetal survival. The current sedentary lifestyle exaggerates these metabolic changes and results in syndromes that increase the risk for a number of metabolic, cardiovascular and immunological disorders of pregnancy.

When confronted by the idea that it is counterintuitive to think exercise in pregnancy might be safe (let alone beneficial) I am dumbfounded. To me, it is counterintuitive to think that a sedentary lifestyle in pregnancy might be safe!

Burning Calories in Pregnancy Improves Outcomes!

What is the evidence that exercise in pregnancy is beneficial? Keep in mind that some studies have been executed more expertly than others. But, what is compelling is that numerous well-respected researchers have sought to test the hypothesis that exercise is not safe, but come away with results that indicate the opposite!

Here are some of the major findings:

• The placenta is larger and has more transport surface in exercisers than sedentary women

• The fetuses of (aerobic) exercising mothers make beneficial cardiovascular adaptations

• Women who do aerobic exercise are less likely to develop severe preeclampsia or gestational diabetes, and the long term health problems that accompany these disorders

• Women who are aerobically fit recover from birth 10 times faster than sedentary women (as measured by time needed to metabolize free radicals produced in labor)

• Women who exercise in pregnancy are more likely to be physically fit in midlife

What revisions would most benefit pregnant women, their offspring, families and communities?

1. Reward healthy behaviors. A system that provides reduced premiums for health care for women who exercise, eat well, do not smoke and are in a normal weight range is evidence-based.

Yes! We could provide financial incentives for being healthy during pregnancy. Why? Healthy moms have healthy babies; healthy babies cost the payer less money.

2. Review best practices. Is a 40 or 50% cesarean rate the best practice?  Accompanying the rise in cesarean births is growing information that babies born by cesarean are at increased risk for a number of immune disorders. But the business model of medicine rewards cesarean because it both pays the provider more and is defensive medical practice.

Fetal monitoring to determine if a cesarean may be necessary, is wrong 3/4 of the time. In an effort to change this, guidelines are changing for the use of monitors during labor. What is the evidence that this change of practice is beneficial? Will it lead to more or less monitoring, which may itself be an intervention that can disrupt normal labor?

Why does insurance pay for cesareans? Well, they will do it once. After all, the care providers have to practice defensive medicine. But, once you have a cesarean, you become a risk for the insurance company (they know what the research says about cesareans and offspring health problems) and may be denied insurance. They can no longer afford you.

Because care providers are paid fee for service and must practice defensive medicine, pregnancy and birth have become increasingly burdened with intervening procedures that do not necessarily promote a healthy pregnancy or birth process. How is this playing out? Increasingly, we see women giving birth in what they perceive as a more supportive and health-inducing setting:  their own homes. Think of it this way:  many women now believe that it is safer to stay home than go to a hospital to give birth.

Unless health care becomes about best practices and healthy outcomes — not price, size, and getting paid for passing money back and forth — the U.S. will continue to have some of the worst maternal/infant outcomes in the developed world.

Preconditions

Pre-existing factors that can influence health outcomes include genetic factors (family risk for heart disease, for example), environmental factors (living in a building with mold, for example), and behavior (eating well and exercising, for example). In each category, factors will contribute to the health of the mother and eventually to offspring health.

It is important to understand what major genetic factors may affect your offspring and whether the environment or behavior can help offset negative factors. For example, there may be a history of preeclampsia during pregnancy in your family, but vigorous aerobic exercise in the six months prior to pregnancy provides a high degree of protection from this risk. Preeclampsia puts both mother and offspring at risk for complications.

Other genetic factors that may be of consequence include autoimmune disorders, allergies, and metabolic syndromes. For example, so-called “thrifty genes” may predispose you to a high weight gain in pregnancy. But, you may be able to offset health problems associated with this by staying active and eating well.
