teen obesity and heart diseaseI don’t need to tell you that we are in the midst of an obesity epidemic. Sadly, that obesity epidemic has even affected our children. Currently, one third of the adolescent population of the United States and other developed countries is overweight or obese, and those numbers are rapidly increasing.  Teen obesity and heart disease are not uncommon.

You probably also knew already that overweight and obesity in the early years increases the risk of death from cardiovascular disease and other causes among young adults, but a new study suggests that the consequences of overweight during the teen years may be much worse than we thought.

How Was This Study Done?

This study (Twig et al, The New England Journal of Medicine, DOI:10.1056/NEJMoa1503840, Published April 13, 2016) was based on a national database of 2.3 million Israeli adolescents ages 16-19 (average 17.1) for whom height and weight were measure between 1967 and 2010. Israel has such an extraordinarily large database because one year before military service all Israeli adolescents are required to undergo a medical evaluation. This is predominantly a male population because Orthodox women are excluded from service.

military studyIsrael also has a national health service that keeps a comprehensive database of deaths. Therefore, the investigators were able to record all deaths in this group that were attributable to coronary heart disease, stroke, sudden death from an unknown cause, or a combination of all three categories, which they classified as total cardiovascular deaths through June 30, 2011. That means that the median age at the end of the study was around 40.

The investigators divided the subjects into groups based on their BMI (weight (kg)/ height (m)2), a measure of the leanness or obesity of each individual and compared BMI with deaths due to various kinds of heart disease.

What sets this study apart from all previous studies was the size of the database (2.3 million). Because of the very large number of subjects in the study the investigators:

  1.  Were able to accurately measure the effect of BMI on cardiovascular deaths in people aged 30-40, an age at which the incidence of cardiovascular deaths is relatively low.
  2. Were able to divide the subjects into seven BMI groupings, rather than the two or three used in most previous studies.

For example, most previous studies have simply compared individuals who were obese (BMI > 95th percentile) or overweight (BMI in 85th to 94th percentile) with everyone in the normal range (BMI in the 5th to 84th percentile).

This study further separated individuals within the normal BMI range to high-normal (BMI in the 75th to 84th percentile), mid-normal (BMI in the 50th to 74thpercentile), and low normal (BMI in the 25th to 49th percentile) and compared each group to individuals with BMIs in the 5th to 24th percentile.

Teen Obesity and Heart Disease:  Will Your Teen Die Prematurely?

The results of the study were pretty sobering.

teen deaths from heart disease1)     For teens who are obese (210 pounds for a 6’ boy and 175 pounds for a 5’6” girl) at 17, their risk of dying prematurely from:

  • Heart attack increases 4.9 fold
  • Stroke increases 2.6 fold
  • All cardiovascular causes increases 3.5 fold
  • The increased risk of dying from all kinds of cardiovascular disease was 2-fold greater by age 27 and 4-fold greater by the time the subjects had reached age 37-47.

2)     For teens who are overweight (185-209 pounds for a 6’ boy and 155-174 pounds for a 5’6” girl) at 17, their risk of dying prematurely from:

  • Heart attack increases 3.0 fold
  • Stroke increases 1.8 fold
  • All cardiovascular causes increases 2.2 fold

3)     For teens who are at high-normal weight (175-184 pounds for a 6’ boy and 145-154 pounds for a 5’6” girl) at 17, their risk of dying prematurely from:

  • Heart attack increases 2.0 fold
  • Stroke increases 1.4 fold
  • All cardiovascular causes increases 1.8 fold

4)     Perhaps the most surprising finding was that even for teens who are at mid-normal weight (155-174 pounds for a 6’ boy and 130-144 pounds for a 5’6” girl) at 17, their risk of dying prematurely from:

  • Heart attack increase 1.5 fold
  • All cardiovascular causes increases 1.3 fold

5)     The number of teen girls in the study was much less, but they appeared to have similar increased risk of cardiovascular deaths with increased BMI compared to the boys in the study.

The message is clear on teen obesity and heart disease.

  • Obesity and overweight during the teen years are killers. They can lead to a significant increase in deaths due to heart attacks, strokes and all cause cardiovascular mortality long before those teens reach the age of 50.
  • Even teens who are in the higher end of what is considered a normal weight range are at increased risk of cardiovascular mortality long before they reach their golden years.

The Bottom Line

A recent study compared the BMI of 2.3 million Israeli teens (average age 17) with cardiovascular deaths over the next few decades

1)     Teens who were overweight or obese had a 2-fold greater risk of dying from cardiovascular disease by age 27 and 4-fold greater risk by the time they reached age 37-47.

2)     Even teens who were at the upper end of the normal weight range had a 1.8-fold increased risk of dying from cardiovascular disease.

The message is clear.

  • Obesity and overweight during the teen years are killers. They can lead to a significant increase in deaths due to heart attacks, strokes and all cause cardiovascular mortality long before those teens reach the age of 50.
  • Even teens who are in the higher end of what is considered a normal weight range are at increased risk of cardiovascular mortality before they reach their golden years.

One of the Little known Causes of Headaches

Posted August 15, 2017 by Dr. Steve Chaney

Your Sleeping Position May Be Causing Your Headaches!

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,
