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.

One of the Little known Causes of Headaches

Posted August 15, 2017 by Dr. Steve Chaney

Your Sleeping Position May Be Causing Your Headaches!

Author: Julie Donnelly, LMT – The Pain Relief Expert

Can sleeping position be one of the causes of headaches?  

A Sleeping position that has your head tilted puts pressure on your spinal cord and will cause headaches. I’ve seen it happen hundreds of times, and the reasoning is so logical it’s easy to understand.

causes of headachesYour spinal cord runs from your brain, through each of your vertebrae, down your arms and legs. Nerves pass out of the vertebrae and go to every cell in your body, including each of your organs. When you are sleeping it is important to keep your head, neck, and spine in a horizontal plane so you aren’t straining the muscles that insert into your vertebrae.

The graphic above is a close-up of your skull and the cervical (neck) vertebrae. Your nerves are shown in yellow, and your artery is shown in red.  Consider what happens if you hold your head to one side for hours. You can notice that the nerves and artery will likely be press upon. Also, since your spinal cord comes down the inside of the vertebrae, it will also be impinged.

In 2004 the Archives of Internal Medicine published an article stating that 1 out of 13 people have morning headaches. It’s interesting to note that the article never mentions the spinal cord being impinged by the vertebrae. That’s a major oversight!

Muscles merge into tendons, and the tendons insert into the bone.  As you stayed in the tilted position for hours, the muscles actually shortened to the new length.  Then you try to turn over, but the short muscles are holding your cervical vertebrae tightly, and they can’t lengthen.

The weight of your head pulls on the vertebrae, putting even more pressure on your spinal cord and nerves.  Plus, the tight muscles are pulling on the bones, causing pain on the bone.

Your Pillow is Involved in Your Sleeping Position and the Causes of  Headaches

The analogy I always use is; just as pulling your hair hurts your scalp, the muscle pulling on the tendons hurts the bone where it inserts.  In this case it is your neck muscles putting a strain on your cervical bones.  For example, if you sleep on your left side and your pillow is too thick, your head will be tilted up toward the ceiling. This position tightens the muscles on the right side of your neck.

Dozing off while sitting in a car waiting for someone to arrive, or while working for hours at your desk can also horizontal line sleepcause headaches. The pictures above show a strain on the neck when you fall asleep without any support on your neck. Both of these people will wake up with a headache, and with stiffness in their neck.

The best sleeping position to prevent headaches is to have your pillow adjusted so your head, neck, and spine are in a horizontal line. Play with your pillows, putting two thin pillows into one case if necessary. If your pillow is too thick try to open up a corner and pull out some of the stuffing.

If you sleep on your back and have your head on the mattress, your spine is straight. All you need is a little neck pillow for support, and a pillow under your knees.

Stomach sleeping is the worst sleeping position for not only headaches, but so many other aches and pains. It’s a tough habit to break, but it can be done. This sleeping position deserves its own blog, which I will do in the future.

 

Treating the Muscles That Cause Headaches

sleeping position causes of headachesAll of the muscles that originate or insert into your cervical vertebrae, and many that insert into your shoulder and upper back, need to be treated.  The treatments are all taught in Treat Yourself to Pain Free Living, in the neck and shoulder chapters.  Here is one treatment that will help you get relief.

Take either a tennis ball or the Perfect Ball (which really is Perfect because it has a solid center and soft outside) and press into your shoulder as shown.  You are treating a muscle called Levator Scapulae which pulls your cervical vertebrae out of alignment when it is tight.

Hold the press for about 30 seconds, release, and then press again.

Your pillow is a key to neck pain and headaches caused by your sleeping position.  It’s worth the time and energy to investigate how you sleep and correct your pillow.  I believe this blog will help you find the solution and will insure you have restful sleep each night.

Wishing you well,
