What is Fetal Programming?

What is fetal pro­gram­ming? Every per­son liv­ing on earth was first exposed to a uter­ine envi­ron­ment that helped deter­mine their life­time health and devel­op­ment. The term for this phe­nom­e­non is fetal pro­gram­ming. It is a hot topic and deserves attention.

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.

How to Get Pregnant — Coaching Topic #1

So let’s get on with the topic of How to Get Preg­nant, start­ing with why do we need to know this?

In the past few decades, the aver­age age for a first preg­nancy in the U.S. has moved from the mid twen­ties into the mid thir­ties. In the same time period, the facts of con­cep­tion — sperm enters egg released in mid cycle, then zygote implants in the uterus, along with how sex allows this to hap­pen and how to pre­vent it — seems to have dis­ap­peared from mid­dle and high school health classes. If that weren’t enough, as women have become more and more essen­tial in the work force, the cost of hav­ing chil­dren as well as start­ing later, have dri­ven down the birth rate. Sim­i­lar con­di­tions exist in most devel­oped nations, although teen preg­nancy rates are lower every­where else.

The birthing pop­u­la­tion has bifur­cated — we see older women (over 35) and teens as the major groups hav­ing chil­dren. On the one hand we have been work­ing to reduce teen preg­nancy while help­ing older and older women become first time moms. To a cer­tain extent, they need the same infor­ma­tion; its just that with teens we use this infor­ma­tion to pre­vent preg­nancy and with older women we use infor­ma­tion to help them increase their odds of get­ting pregnant.

Under­stand­ing the men­strual cycle, ovu­la­tion, chart­ing tem­per­a­ture — all the basic tech­niques of using the “nat­ural” method of birth con­trol — have become the first steps of the how-to-get-pregnant coaches. Beyond this, a num­ber of sites have their own essen­tial lists to help women be healthy and ready. Sites such as gettingpregnant.com, pregnancy.org/getting-pregnant, and storknet.com/cubbies/preconception/ pro­vide addi­tional infor­ma­tion. Many sug­ges­tions — things to avoid eat­ing, what pro­teins are needed for ovu­la­tion, how to reduce stress, what to do if there are sperm prob­lems, how to find IVF clin­ics, donors and sur­ro­gates — are addressed.

How effec­tive are these sug­ges­tions? Well, research tells us they are some­what effec­tive. None of the sites I con­tacted answered my query about how they mea­sure or assess con­sumer out­comes when fol­low­ing their suggestions.

An inter­est­ing arti­cle in the NY Times 9/1/2011, enti­tled Are You as Fer­tile as You Look? openened with this sen­tence: “FORTY may be the new 30, but try telling that to your ovaries.” The real­ity is that being under 35 is still the best pre­dic­tor of how dif­fi­cult it may be for you to become preg­nant. As the arti­cle makes clear, look­ing 30 and being 30 are not the same thing. Even healthy liv­ing does not pre­vent the loss of good eggs.

So, what con­clu­sions can we draw? First, even if you come from a “fer­tile fam­ily,” it may behoove you to have your chil­dren in your late 20s or early 30s. Sec­ond, if you are putting off hav­ing chil­dren beyond that time, ask your­self what extremes you are will­ing to go to to have your own bio­log­i­cal off­spring. And, third, con­sider adop­tion. Frankly, it would be won­der­ful if adop­tion were eas­ier, but in the drive to con­ceive at later and later ages we see the hand of biol­ogy and under­stand why adop­tion is not easy:  Our own off­spring — our own DNA out there in the world — is a heady motivation.

If you are on the path­way of becom­ing preg­nant, being under 35 is the best ally you have. If not, maybe some of the sug­ges­tions on the web will work for you. What­ever you decide, all the best.

One part­ing com­ment:  Reg­u­lar mod­er­ate exer­cise — while it helps you stay young and healthy — will not pre­vent your eggs from being popped out every month. It will help you have a healthy preg­nancy if you con­ceive, so stay with it!

Birth of Pregnancy Exercise: Evolution of DTP

Some­times it is fun to look back at the long road to the present! Recently, I was inter­viewed by our local online media out­let (the Bran­ford CT Patch) and was really thrilled with the result­ing story. It focused on the 30 year road of DTP and I thought you might find it interesting.

Here is the link to the story and the subtitle:

http://branford.patch.com/articles/ann-cowlin-a-prenatal-fitness-pioneer-celebrates-30-years-of-work

What started as a “fledg­ling exper­i­ment” has become one Bran­ford woman’s life work.

Thank you for tak­ing a look!

Still look­ing for new ways to develop core strength & coor­di­na­tion for new moms…start with the pos­ture on the left (inhale) and move to the one on the right (exhale). Keep the trans­verse abdom­i­nal sucked in. Repeat.…

34 Years of Mom & Baby Fitness!

Wow! Look­ing over 34 years of prepar­ing moms for birth at Yale and beyond, we reflect on all the changes we have seen over the years. The impact of the inter­net is felt every­where now, includ­ing the con­sumer move­ment to improve prepa­ra­tion for birth and inform­ing women of the choices avail­able to them as the pre­pare for this major life event. Research has long demon­strated that aer­o­bic exer­cise, strength train­ing and mind/body exer­cise are effec­tive as a prepa­ra­tion for a tol­er­a­ble labor with reduc­tion of risk for dis­or­ders and med­ical inter­ven­tions. The inter­net has helped tremen­dously in get­ting the word out. It’s been a long road…50 years or more…to show that exer­cise is safe and effec­tive for moms-to-be. We are glad to play a part in this progress!

Safe Motherhood

The chal­lenges to safe moth­er­hood vary depend­ing where in the world you live. In some areas the chal­lenge may be to get ade­quate nutri­tion or clean water; in other areas, it may be to pre­vent infec­tion; and in still other loca­tions it may be try­ing to avoid preg­nancy before your body is ready or get­ting access to pre­na­tal care. In the U.S., it may mean avoid­ing being seden­tary and mak­ing poor food choices, or hav­ing to deal with the high tech­nol­ogy envi­ron­ment of med­ical birth that can sab­o­tage the innate phys­i­o­log­i­cal process of labor and birth.

Birth begins the bond­ing or unique love between mother and child.

The biol­ogy of birth is a com­plex series of cause-effect processes…baby’s brain releases chem­i­cal sig­nals to the mother and the pla­centa begins to man­i­fest the mater­nal immune system’s rejec­tion of the fetus.

To help the ball get rolling, relax­ation (the trophotropic response) helps pro­mote the release of oxy­tocin. With the help of grav­ity, the head presses on the cervix, ampli­fy­ing the uter­ine con­trac­tions. After an ultra-distance aer­o­bic endurance test, the cervix opens enough to let the baby move into the vagina and the mother’s dis­com­fort moves from sharp cramp­ing into the bony struc­ture as she tran­si­tions to the strength test of push­ing. She tran­si­tions. Relax­ation mod­u­lates into an ergotropic — adrenal — response to gather her power.

Push­ing is an inter­est­ing term…more mas­cu­line, I think, than the one I pre­fer:  Releas­ing. Releas­ing or let­ting go of the baby. It’s a cathar­sis. In this por­tion of the labor another set of impor­tant processes help the baby clear its lungs of amni­otic fluid, stim­u­late its adrenal sys­tem and chal­lenge its immune sys­tem, as the con­trac­tions drive the baby down­ward. The mother’s deep trans­verse abdom­i­nal mus­cles — if strong enough — squeeze the uterus like a tube of tooth paste, to aid this expul­sion. In the mean­time, the labor is help­ing set up the mother to fall in love and pro­duce milk. When the baby emerges and moves onto the mother’s chest, s/he smells and tastes the mother, rec­og­niz­ing her mother’s fla­vor and set­ting up the poten­tial for bonding.

Any way you slice it, there are two parts to safe moth­er­hood. One is a safe preg­nancy…healthy nutri­tion, phys­i­cal fit­ness, safe water, infec­tion pre­ven­tion, sup­port and a safe envi­ron­ment. The other is a safe labor. In a safe labor, there is both an envi­ron­ment that pro­motes the nat­ural process of labor and the means nec­es­sary for med­ical assis­tance when needed. Women die at an alarm­ing rate from preg­nancy or birth-related prob­lems. Despite some progress made in recent years, women con­tinue to die every minute as a result of being preg­nant or giv­ing birth.

What keeps us from hav­ing a bet­ter record on moth­er­hood is often lack of care in the devel­op­ing world and too much inter­ven­tion in the U.S.. They are two sides of a coin. Moth­ers’ expe­ri­ence and health needs are not on equal foot­ing with other cul­tural val­ues. In places where basic pre­na­tal care or fam­ily plan­ning are low pri­or­i­ties, at-risk women are vul­ner­a­ble to the phys­i­cal stresses of preg­nancy and birth. In the U.S., machine-measured data is para­mount, even if it pro­duces high rates of false pos­i­tives, unnec­es­sary inter­ven­tions or coun­ter­pro­duc­tive pro­ce­dures. We are learn­ing that obe­sity and seden­tary lifestyles have detri­men­tal effects, but fewer preg­nant women than their non-pregnant coun­ter­parts exercise.

Despite the money spent to sup­port the tech­no­log­i­cal model of preg­nancy and birth in the U.S., there are parts of the world with lower rates of mater­nal deaths — espe­cially Scan­di­navia, North­ern Europe and parts of the Mediter­ranean and Mid­dle East (Greece, the United Arab Emi­rates, Israel, Italy and Croa­tia). In fact, in the U.S., mater­nal deaths are on the rise.

It’s a tricky busi­ness. Clearly West­ern med­i­cine has a lot to offer the devel­op­ing world when there are med­ical con­cerns. On the other hand, import­ing the U.S. model could cre­ate more prob­lems than it solves. Instead, the micro-solutions now being devel­oped in many loca­tions will be observed and evi­dence col­lected by orga­ni­za­tions such as the White Rib­bon Alliance and UNICEF.

There is an effec­tive inter­na­tional mid­wives model adopted by JHPIEGO, the Johns Hop­kins NGO work­ing toward improved birthing out­comes. It assesses the local power struc­ture, social con­nec­tions, poten­tial for trained birth assis­tants, and loca­tion of avail­able trans­porta­tion to cre­ate a net­work so that locals will know when a labor is in trou­ble and who can get the woman to the near­est hospital.

In the U.S., there are in-hospital birth cen­ters that allow low-risk moth­ers the oppor­tu­nity to labor and birth in a set­ting designed to encour­age the innate processes. Women are begin­ning to vote with their feet…staying home for birth. Women are going abroad to give birth. At the same time, women are com­ing to this coun­try to give birth, believ­ing it is safer than where they are. There are sev­eral ways these scenes could play out.

But, I’ll wager, improv­ing out­comes will involve com­pro­mise:  Watch­ful­ness and sup­port in most births, plus bet­ter ways to assess dan­ger and pro­vide tech­nol­ogy. No mat­ter where you live in the world, the solu­tion may be essen­tially the same.

Active Pregnancy — the rationale

Mov­ing into Motherhood

It’s time to hit the main theme again:  Aer­o­bi­cally fit women are at reduced risk for things that go wrong in preg­nancy, improve their tol­er­ance for labor and birth, and recover more rapidly in the post­par­tum period.

Mov­ing into Motherhood

The arrival of the hol­i­days pro­vides a good rea­son to bring this up, yet again! Preg­nancy is a gate­way time in women’s lives…we become more aware of our bod­ies, our sen­sa­tions, our feel­ings, our needs, and how ver­sa­tile and amaz­ing our bod­ies are. We can make peo­ple with our bod­ies! Dur­ing preg­nancy, we often take precautions…we eat more care­fully, avoid tox­ins, try to avoid stress. When the hol­i­days arrive, we see indul­gent behav­ior in a dif­fer­ent light.

Yet, even with all this focus on behav­ior, we some­times miss the biggest aid to a healthy preg­nancy:  phys­i­cal fit­ness. Research clearly demon­strates that fit women do bet­ter, are health­ier and hap­pier. More and more in the U.S. we see dis­or­ders of nor­mal organ func­tion that accom­pany seden­tary pregnancy.

Let’s look at this a lit­tle closer (yes, I am going to repeat myself some more, but it is an impor­tant con­cept to spread). We live in a body model that rewards an active lifestyle.

Being seden­tary causes things to go wrong

Not mov­ing cre­ates bio­chem­i­cal imbal­ances because the car­dio­vas­cu­lar sys­tem atro­phies and mol­e­cules cre­ated in the brain or brought in through the diges­tion may not get where they need to go for a healthy metabolism.

Your car­dio­vas­cu­la­ture is the high­way that brings usable sub­stances to the place they are used. You have to help it grow and develop, use it to pump things around and give it a chance to be healthy. Aer­o­bic fit­ness does all these things.

Advice for young women of child­bear­ing age

If you are think­ing of preg­nancy, have recently become preg­nant, or work with women of child­bear­ing age, we encour­age you to open avenues of activ­ity for your­self or oth­ers in this pop­u­la­tion. You can learn more from our blog dancingthrupregnancy.wordpress.com. You can seek out local pre/postnatal fit­ness experts on this site. Yoga is nice…we use some of it in our work, along other spe­cific exer­cises for which there is a direct health ben­e­fit. But, we also see yoga con­verts who come into our pro­gram in mid preg­nancy unable to breathe after walk­ing up a flight of stairs. How will they do in labor? Not as well as those who have been doing aer­o­bic dance or an ellip­ti­cal machine 2 or 3 times a week.

The AHA/ACSM guide­lines for the amount of aer­o­bic exer­cise needed to improve car­dio­vas­cu­lar sta­tus hold true for preg­nant women just as they do for the rest of the pop­u­la­tion – a min­i­mum of 150 min­utes of mod­er­ate, or 75 min­utes of vig­or­ous, or a com­bi­na­tion of these lev­els of inten­sity, per week. If you are not get­ting this level of activ­ity, you are putting your health – and that of your off­spring – at risk.

Buy the Book!

Recently, we have expe­ri­enced grow­ing inter­est in infor­ma­tion included in the text­book, Women’s Fit­ness Pro­gram Devel­op­ment. So, we decided that site read­ers might want to pur­chase this text if they are seri­ously inter­ested in sub­jects per­tain­ing to women’s health fit­ness. The book opens with a chap­ter on how women dif­fer from men in their phys­i­cal, men­tal, emo­tional and social devel­op­ment and how these dif­fer­ences affect our moti­va­tion to be active. Sec­tions on ado­les­cence, preg­nancy, the post­par­tum period and menopause explain what hap­pens dur­ing these crit­i­cal and uniquely female life tran­si­tions, what is known about the impact of exer­cise on health dur­ing these times, and how to develop effec­tive pro­gram­ming for these pop­u­la­tions. It is avail­able through the pub­lisher, Human Kinet­ics, or through Ama­zon or Barnes & Noble.

Fitness Starts Early!

Preg­nancy fit­ness is not only impor­tant for moms, but for the fetus as well. Evi­dence is clear that aer­o­bic fit­ness improves brain, heart, immune and meta­bolic function…at all ages, includ­ing in utero. If con­tin­ued early in life, healthy phys­i­cal adap­ta­tions that occur in the uterus become rein­forced behav­ior, prepar­ing a good foun­da­tion for a healthy lifestyle. Babies are acute observers of move­ment and activ­ity, and learn from each other. A key com­po­nent of a good mom-baby pro­gram is the inter­ac­tion of the babies them­selves. A good teacher will facil­i­tate healthy activ­ity among our small­est class members!

There is grow­ing evi­dence that at all ages, aer­o­bic fit­ness pro­duces the great­est num­ber of ben­e­fits. Recently, researchers deter­mined that aer­o­bic fit­ness in 9 and 10 year olds pro­duced ben­e­fits in the devel­op­ment of two impor­tant brain regions — the basal gan­glia and the hip­pocam­pus — that are sig­nif­i­cant fac­tors in problem-solving intel­li­gence. This is just one of the lat­est reports that tells us the capac­ity to absorb and use oxy­gen (which improves with aer­o­bic fit­ness) is a key to health, qual­ity and length of life…beginning in the womb!

CDC Fitness Guidelines Include Pregnancy

Recent CDC Guide­lines on Exer­cise for the gen­eral pop­u­la­tion include preg­nant and post­par­tum women. Spe­cific infor­ma­tion for preg­nant women is included at this URL:

http://www.cdc.gov/physicalactivity/everyone/guidelines/pregnancy.html

James Pivarnik, PhD, pres­i­dent of the Amer­i­can Col­lege of Sports Med­i­cine has released a Med­scape video for health care providers encour­ag­ing them to be aware of the fact that the CDC con­sid­ers a min­i­mum of 150 min­utes per week of mod­er­ate activ­ity (or 75 min­utes of vig­or­ous activ­ity for ath­letic women, or a com­bi­na­tion of inten­sity for fit women) to be impor­tant for preg­nant women, along with the gen­eral population.

DTP’s Total Preg­nancy Fit­ness instruc­tors learn how to com­bine activ­i­ties so that women receive an ade­quate amount of exer­cise each week dur­ing their preg­nancy. To find out about becom­ing a teacher, click on Become a Teacher above.
