dha supplementation saves moneyA recent study has estimated that taking DHA supplements during pregnancy, specifically in the last two trimesters, could save the US healthcare system close to $6 billion/year (Shireman et al, Prostaglandins, Leukotrienes and Essential Fatty Acids, 111: 8-10, 2016) .

Another study has come to similar conclusion in Australia (Ahmed et al, Prostaglandins, Leukotrienes and Essential Fatty Acids, 102-103: 5-11, 2015) .

When you have two well done studies by different investigators in different countries that come to the same conclusion, it is time to take the studies seriously and start to ask some important questions. For example:

  • Are these studies true?
  • Should we change our public health recommendations during pregnancy?
  • Is this just a public health issue, or does it affect you personally?

The Value of DHA Supplements During Pregnancy

dha supplements during pregnancyThe US study was called “Kansas University DHA Outcomes Study” (KUDOS). It studied health outcomes for 197 pregnant moms who gave birth to a single baby at the Kansas University Hospital between 2006 and 2010. The moms came from the Kansas City metropolitan area and consisted of 42% moms who self-identified as Black and 58% as other races.

The women were randomly assigned to consume 3 capsules per day containing either 600 mg DHA or a placebo containing corn and soybean oil during their second and third trimesters (starting around 14.5 weeks after gestation). Multiple pregnancy outcomes were assessed, but the main focus was on early preterm birth (infants born before 34 week’s gestation). That’s because a recent meta-analysis has reported that omega-3 fatty acid supplementation during pregnancy reduces early preterm births by 58% (Kar et al, European Journal of Obstetrics & Gynecology and Reproductive Biology 198: 40-46, 2016) .

The results of the KUDOS study were:

  • Taking DHA supplements during pregnancy, specifically in the last two trimesters, reduced early preterm birth from 4.8% to 0.6%.
  • DHA supplementation reduced average hospital costs per infant born in the Kansas Medical Center by $1678. This was primarily because of a significant reduction in the average length of time spent in the neonatal intensive care unit because of the reduction in early preterm births.
  • When the cost of supplementation was taken into account, there was a 10-fold return in hospital cost savings for every dollar spent on supplementation.
  • When the authors extrapolated this analysis to the 4 million live births in the US each year, they estimated a potential savings of $6.6 billion.
  • This corresponds to a net savings of $5.94 billion to the US health care system if you take into account the cost of providing all pregnant women in the US with 600 mg of DHA/day during the last two trimesters of pregnancy.

The authors of the KUDOS study concluded “…a public health policy to increase DHA intake during pregnancy could result in significant cost savings to the health care system in our country”.

Are These Studies True?

truthTruth in science is always elusive. It requires many years of research and multiple clinical studies. However, two well done studies in two different countries have concluded that taking DHA supplements during pregnancy significantly reduces health care costs. In addition, a recent meta-analysis of 6 published clinical studies (Kar et al, European Journal of Obstetrics & Gynecology and Reproductive Biology 198: 40-46, 2016) has concluded that omega-3 fatty acid supplementation during pregnancy reduces early preterm births by 58%.

These are all small studies, but their results are remarkably consistent. If you were to generalize the conclusions of all these studies into a statement saying “Omega-3 fatty acid supplementation during pregnancy significantly reduces health care costs”, there is a good probability that statement would be true. However:

  • The exact cost savings is uncertain.
  • The source of omega-3s (DHA, EPA, or a mixture of the two) is uncertain.
  • The amount of omega-3 fatty acids needed to reduce early preterm births is uncertain.

Let’s look at each of these in turn:

Cost Savings of Using DHA Supplements During Pregnancy

  • On the minus side, 42% of the women in the KUDOS study were Black, while the national average is 16%. That is significant because the rate of early preterm births is twice as high for black women as it is for White and Asian women. If the results of the KUDOD study were extrapolated to the percentage of Black women in the US population, the cost savings to the US health care system would only be around $4 billion – still a pretty substantial number!
  • On the plus side, the initial hospital costs associated with early preterm birth are just the tip of the iceberg. There are also considerable long-term expenses for special education services associated with disabling conditions common with premature infants.  A recent study (Mangham et al, Pediatrics 123: e312-e327, 2009) calculated the costs of preterm birth in the UK from birth to 18 years of age and came up with an estimate of $4.567 billion in US dollars. If we assume that omega-3 supplementation results in a 58% decrease in early preterm birth (Kar et al, European Journal of Obstetrics & Gynecology and Reproductive Biology 198: 40-46, 2016) and extrapolate that cost savings to the US population, the total cost savings would be $13.2 billion. Now we’re talking real money!

Source of Omega-3s:

  • DHA has been the focus of the two most recent studies on cost savings because of the role of DHA in nerve, brain and visual development, but EPA is also likely to be important in neonatal development. In addition, the efficiency of conversion of EPA to DHA is very high.
  • In fact, when we look at the individual studies included in the meta-analysis described above (Kar et al, European Journal of Obstetrics & Gynecology and Reproductive Biology 198: 40-46, 2016), DHA, EPA, and EPA+DHA supplementation all gave comparable reductions in early preterm births.

Amount of Omega-3s:

  • While the 600 mg/day used in the KUDOS study is probably a good starting point, the individual studies in the meta-analysis used a wide range of dose. All of them seemed to have at least some efficacy in reducing early preterm births. Obviously, more studies are needed to determine the optimal dose.

What Does This Mean For You?

All this talk about reducing health care costs may seem esoteric. You may be wondering “What does this have to do with me?”

  • Don’t be lulled to complacency by the estimated cost savings of $1678/birth mentioned above. That is the average costs of all births. Early preterm births represent only 4.78% of all the births in the study. If you give birth to a baby earlier than 34 weeks of gestation, there is a high probability your infant will end up in the neonatal intensive care unit and your health care costs will be orders of magnitude more than $1678. How that affects your wallet will depend on your insurance plan.
  • Early preterm birth is associated with increased risk of global and selective cognitive defects. These can range from relatively mild impairment of IQ, memory, executive function, non-verbal skills, and motor skills to much more serious conditions like cerebral palsy, mental retardation, and disorders of psychological development. The possibility of avoiding those kinds of defects in your child is priceless.

 

The Bottom Line

  • Recent studies in the US and Australia have shown that taking 600 mg of DHA supplements during pregnancy during the last two trimesters  significantly reduces early preterm births (infants born before 34 weeks gestation) resulting in an estimated savings to the US health care system of around $6 billion/year.
  • Other studies suggest that supplementation with EPA and EPA+DHA mixtures give similar results.
  • Discussions of cost savings to the US healthcare system sound somewhat esoteric. However, if you are pregnant or considering becoming pregnant, there are real benefits to you associated with reducing the risk of early preterm birth. That is because:
  • The costs associated with early preterm births are substantial. How much they affect your wallet will depend on your health insurance policy.
  • Early preterm births are associated with a variety of global and selective cognitive defects (for details, read the article above). The possibility of avoiding those kinds of defects in your child is priceless.

How to Choose the Right Pillow

Posted April 17, 2018 by Dr. Steve Chaney

Wake Up Each Morning Pain Free

how to choose the right pillow without headachesThe way you sleep is often a key to discovering the cause of headaches and more. If you wake up with neck pain, a headache, or you suffer from ringing in your ears, dizziness, or ear pain, there is a good possibility that it may be caused by the way you are sleeping. Your pillow may be the culprit.  But if you need to know how to choose the right pillow for you, it’s easy.   It just takes a little “investigation.”

 

How to Choose the Right Pillow if You Sleep On Your Side

Your head, neck, and spine need to always stay in a nice straight line, just as it is when you are standing up, but that takes a little thought and understanding of the way you sleep.  So, get comfy in your bed and then notice how your head is resting.

how to choose the right pillow to sleep painfreeIf you sleep on your side, your pillow needs to be just the right size, so your head doesn’t point down toward the mattress (your pillow is too soft) or up to the ceiling (your pillow is too thick). Either of these positions will make the muscles on the side of your neck stay in the contracted position for hours and pull your vertebrae in that direction, especially when you try to turn over to your other side.

Your SCM Muscle May Cause Serious Problems

You also need to notice if you turn your head a bit, especially if you are turning into your pillow or turning your head up toward away from your pillow. In either of these two cases you will be causing your sternocleidomastoid (SCM for short) to be held shortened for hours.

Your SCM originates on your collarbone and inserts into the bone behind your ear.  When it contracts you turn your head to the opposite side. However, if the muscle is tight (for example, when you’ve held your head turned toward one side for an extended period of time) and then you bring your head back so you are facing forward, the tight muscle will pull on the bone behind your ear and cause havoc.

The symptoms for a tight SCM are tinnitus (ringing in the ear), dizziness, loss of equilibrium, ear pain, headaches, pain in the eye and around the skull, pain at the top of the head, and even pain in the throat. Amazing! What’s even more amazing is that it’s rare that this muscle is considered when a medical professional is searching for the cause of your symptoms.

These are the things to know when considering how to choose the right pillow if you sleep on your side.

How To Choose The Right Pillow If You Sleep On Your Back

how to choose the right pillow for sleeping on your backIf you sleep on your back, your head should be on the mattress (not propped up with a pillow) and you should have a tiny support (like a folded washcloth) under your neck.  Or, you can have a wedge pillow that starts at your mid-back and gently raises your entire trunk and head up while still allowing your head and back to be in a straight line.

It’s always a challenge for people who toss and turn during the night, sometimes on their side and sometimes on their back.  The best thing I’ve found for this situation is to have the pillow below shoulder level so when you turn on your side your shoulder will automatically slide to the edge of the pillow while still supporting your head properly, and when you turn onto your back, the pillow will start at shoulder level so your head and neck are supported, but your head is being pushed in a way that causes your chin to move down to your chest.

hip pain causes and treatment pain freeIt’s tricky, but I can personally attest to the fact that it will work.  I can always tell when I’ve had my head tilted (I toss and turn during the night) because I will wake with a headache. When that happens I’m grateful that I know how to self-treat the muscles of my neck and shoulders so the headache is eliminated quickly.  If you already have Treat Yourself to Pain Free Living,  you can self-treat all your neck and shoulder muscles to release the tension.

How To Choose The Right Pillow If You Sleep On Your Stomach

If you sleep on your stomach, this is the one position that is so bad that it behooves you to force yourself to change your position. Your head is turned to the side and held still for hours, putting a severe strain on all your cervical and upper thoracic vertebrae. Not only will this cause headaches, tinnitus, and a list of other pains, but it can cause problems down your entire spine. It can also impinge on the nerves that pass through the vertebrae on their way to your organs.

If you do sleep that way, let me know and I’ll give you some suggestions that work to change your habit of sleeping. It takes time and energy, but the results are worth the effort.

In every case, the way you sleep may cause neck pain that won’t go away until the pillow situation is resolved.

Now you should know how to choose the right pillow for the way you sleep.

Wishing you well,
