Extreme obesity may shorten life expectancy up to 14 years

Extreme obesity may shorten life expectancy up to 14 years

Adults with extreme obesity have increased risks of dying at a young age from cancer and many other causes including heart disease, stroke, diabetes, and kidney and liver diseases, according to results of an analysis of data pooled from 20 large studies of people from three countries. The study, led by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health, found that people with class III (or extreme) obesity had a dramatic reduction in life expectancy compared with people of normal weight.

The findings appeared July 8, 2014, in PLOS Medicine.

“While once a relatively uncommon condition, the prevalence of class III, or extreme, obesity is on the rise. In the United States, for example, six percent of adults are now classified as extremely obese, which, for a person of average height, is more than 100 pounds over the recommended range for normal weight,” said Cari Kitahara, Ph.D., Division of Cancer Epidemiology and Genetics, NCI, and lead author of the study. “Prior to our study, little had been known about the risk of premature death associated with extreme obesity.”

In the study, researchers classified participants according to their body mass index (BMI), which is a measure of total body fat and is calculated by dividing a person’s weight in kilograms by their height in meters squared. BMI classifications (kilogram/meter-squared) are:

  • Normal weight: 18.5-24.9
  • Overweight: 25.0- 29.9
  • Class I obesity: 30.0-34.9
  • Class II obesity: 35.0-39.9
  • Class III obesity: 40.0 or higher
Fat Loss

The 20 studies that were analyzed included adults from the United States, Sweden and Australia. These groups form a major part of the NCI Cohort Consortium, which is a large-scale partnership that identifies risk factors for cancer death. After excluding individuals who had ever smoked or had a history of certain diseases, the researchers evaluated the risk of premature death overall and the risk of premature death from specific causes in more than 9,500 individuals who were class III obese and 304,000 others who were classified as normal weight.

The researchers found that the risk of dying overall and from most major health causes rose continuously with increasing BMI within the class III obesity group. Statistical analyses of the pooled data indicated that the excess numbers of deaths in the class III obesity group were mostly due to heart disease, cancer and diabetes. Years of life lost ranged from 6.5 years for participants with a BMI of 40-44.9 to 13.7 years for a BMI of 55-59.9. To provide context, the researchers found that the number of years of life lost for class III obesity was equal or higher than that of current (versus never) cigarette smokers among normal-weight participants in the same study.

The accuracy of the study findings is limited by the use of mostly self-reported height and weight measurements and by the use of BMI as the sole measure of

    UP24 — the Holistic Wrist gets better!, December 7, 2013
    RST10 (USA) –


    Last November, I reviewed the Jawbone UP, and later compared it to the Fitbit Flex. A year later, Jawbone has now released the UP24. This review will primarily focus on making a choice between UP, UP24 and Fitbit Flex. When I originally reviewed the devices, I thought the main differences would be in the hardware appearance and fit/feel. I was a bit wrong– the biggest functionality difference was in the quality, function and aesthetic value of the software that comes with it. With the UP24 now having bluetooth syncing, the biggest difference for me is now only the software. I’ll let you make your own conclusions.

    And now a year later, I will refresh my thoughts about the UP & Flex devices, and how the UP24 adds to the mix of options.

    If you want to read my original in depth review of the UP, you can see it here:

    http://www.amazon.com/review/R1CVXEEYIAIR0W/ref=cm_cr_rdp_perm (copy & paste if click isn’t allowed)

    If you want to read my original review of the Fitbit One, you can see it here:
    http://www.amazon.com/review/RU12ENFFFWD02/ref=cm_cr_rdp_perm (copy & paste if click isn’t allowed)

    Hardware Comparison
    UP24, UP and Flex are equally easy and comfortable for me to wear. The Flex requires a bit more work to latch, and the UPs both can get in the way when keyboarding on a laptop. Flex is charged by removing a horse pill sized module from the rubber arm band, and plugging it in to USB. UP is charged by plugging the band into an adapter and charging in USB.

    In the UP vs Flex, I got about the same battery life in both, slightly leaning toward the Flex. In UP24, I get about 7 days of battery usage, and this includes it automatically bluetooth syncing. On both devices, if you have a bluetooth 4+ device, you should not see any noticeable drop in battery life by staying connected all the time, and I have not seen a difference.

    I have worn the UP and Flex in extensive swimming, and while none are rated to track your swimming, none encountered any technical issues from the water. The Flex seemed to get a bit “funky/gross” in the portal where the horse pill goes. UP did not get gunky under its cap. Not a deal breaker on the Flex, but a bit more work to maintain.

    From a physical and appearance perspective, the UP24 and UP are identical on the outside. The only difference is that the UP24 has a smaller sync jack inside the cap which is smaller than a standard headphone jack. The UP syncs through a headphone jack of your phone, while the UP24 and Flex use bluetooth.

    Charging in both devices takes about at the same amount of time– 30-60 minutes. I recommend for both that you only use a computer or PC– not a USB wall charger. Some devices fail quickly when charged with more than 1.5V and while I don’t have scientific proof to back it, this is my conclusion from what I’ve seen in discussions and on forums.

    When you buy an UP or UP24, you are committing to a color. When you buy a Flex, you can change the band and can choose any color you can find in a replacement band.

    Wearing each isn’t terribly different. The UP/24 is more like a slap bracelet or a twisty metal that retains its original shape. You stretch it to put it on and it overlaps again to hold on. You can push it tighter if you want, as the rubber grips itself and lets you adjust the tension. The Flex is a thinner but wider band and feels more out of the way, but the clasp can be a bit difficult to operate. For absolute adherence I would say the Flex stays on better in most normal situations. The UP will stay on on roller coasters and probably even a NASA launch, but it can sometimes get entangled in backpack shoulder straps and pull itself from your arm to the strap. This is the only negative thing I have to say about the design of the UP.

    Sleep Function
    All three devices are equally accurate for day time walking for me and report almost identical steps. The UP and UP24 are equally good at sleep monitoring, both deep & shallow. The Fitbit didn’t give nearly as much detail about sleep, and for that matter about activity, intensity, etc. throughout the day in such a clear simple beautiful presentation. The UP products now can auto add your sleep if you forgot to put it in sleep mode and you give it appropriate sleep and awake times. This is a really nice addition since all devices require you to tell them when you sleep, and sometimes it’s easy to forget. Now, you don’t lose that data. A great improvement.

    One feature I like about the UP is the “power nap” function. It learns your sleep patterns, and lets you make it through one cycle of sleep and slowly begins to vibrate to wake you up. For me,…

    My favorite fitness band – UP24 vs Fitbit Force, December 24, 2013

    This review is from: UP 24 by Jawbone – Bluetooth Enabled – Medium – Retail Packaging – Onyx (Wireless Phone Accessory)

    First off, I would like to point out that I own both the Jawbone UP24 and the Fitbit Force and will compare a few features in this review, but if you want a full review on the Fitbit Force I will be posting one on the actual product here soon.


    The UP24 features new curved design on the top, has a smaller headphone jack that is only used for charging, and now syncs via Bluetooth. It has two green LED lights indicating day/night mode, a vibrating motor and a physical button for changing modes.
    There is no clasp, you just twist it on and it fits fairly comfortably if you chose the right size. It is thin and bulky so it tends to get in the way and raise my wrist when I type or use a mouse and can get annoying, I prefer a wider, flatter design.

    The Fitbit Force has a beautiful OLED Screen that shows you all of your stats without having to pull out your phone. The design is very minimalist, and to me is much more comfortable to wear vs the UP. It also does not snag on my jackets or long sleeve shirts and is very thin at the bottom so it is comfortable to type with it on where as the up can be very uncomfortable to type or use a mouse with it on.

    Battery Life – Battery lasts me about 7-8 days and takes about an hour to charge. The manual says to charge it only on a USB port on your computer, but I have charged it using my iPhone wall charger and car charger just fine.

    Pedometer – The UP seems fairly accurate for tracks your steps. If I wave my arm around or if I’m driving, the UP does not count steps whereas the Fitbit Force seems to count steps for any slight movement I make.


    The App is just plain beautiful and intuitive. It is indeed what makes this product what it is. This is where this product shines over the Fitbit Force in my opinion, and is the reason I chose the UP24 even though it lacks a screen. Also works on Android OS.

    Activity Logging – Made extreme simple. You double tap + hold the physical button and it will start logging your work out. Once you are done, do it again and it will add an “activity” to your timeline in which you go to the iOS app and choose what type of activity it was from a preset list [walk, weights, run, cross train, hike, cardio, bike, yoga, stationary bike, pilates, elliptical, basketball, video games, tennis, dance, soccer, ski, other).
    Once you choose your workout, you can choose what the intensity was and it will adjust the calorie burn accordingly. What I also like is that if you forget to log your activity, or remember half way through your workout, after your stop logging the workout you can edit what time you began the workout and it will analyze those prior movements and add them to your logged activity.
    You can also calibrate your UP to your stride, by logging a known walking/running distance (track preferred) and going into your settings and choosing that activity and it will calculate your future walks/runs more accurately.

    The Fitbit Force lacks in this department, it seems very finicky to me, especially after having used the UP. When I log an activity it only shows up on the web app but not on my iOS app (not sure why) and it only lets me name the workout but does not let me choose what type of exercise it was or the intensity level. The only way I have found to do this is to manually add your activity every time which is annoying and not as accurate.

    Sleep tracking – The UP does this very well, you hold the button before you go to sleep until you see the LED moon, and feel it vibrate and press it again when you wake up. If you forget to put it in sleep mode, hit manually add sleep and it will automatically fill in your sleep and estimate what times you slept and woke up based on your movements. I’ve tried purposely sleeping without logging it to test this feature out and it has been very accurate. It likewise includes a power nap mode (double tap 3 times + hold) and you can record your naps throughout the day and it will automatically wake you up based off your sleep cycle.
    It will show you a pretty graph with your deep sleep/light sleep cycle, and how many times you woke up based off your movements throughout the night.

    The Fitbit Force does at pretty good job at tracking sleep also, but doesn’t break down your stats as well as the UP.

    Alarms – One of my favorite features, you can set smart vibration alarms that wake you up slowly based off your sleep cycle, I much prefer this over a loud obnoxious cellphone alarm. There is also an idle alarm that will vibrate after you have been inactive for a preset amount of time to remind you to get off your butt (Something the Fitbit Force does not have).

    Social – I loove the social aspect of the UP (Something the Fitbit Force also lacks) you have the ability to add your friends or random people (which I did because none of my friends own an UP) and cheer…

    Its good buts its bulky., January 9, 2014
    kolimit “Soldier in Iraq” (Near the Border of Iraq) –

    This review is from: UP 24 by Jawbone – Bluetooth Enabled – Medium – Retail Packaging – Onyx (Wireless Phone Accessory)
    I was initially given the Up24 as a Christmas Gift. My fianc? saw that I had been searching for weeks trying to decide the right one. She did some research on her own and decided to get me this product. But after a week, I returned it and brought the Nike Fuelband SE. BUT here is my product review.
    1. Software: The Jawbone's software is FAR ahead of Fitbit and Nike Fuelband. It was very comprehensive and easy to understand. The Software integrated with all the popular Fitness tracking apps, i.e. Myfitness Pal. Fitbit does too. Nike Fuelband does NOT! That's a huge negative for me. I digress. The software automatically synced with Myfitness Pal. What I would offer as a suggestion to Jawbone is to improve the software would allow for the individual to put in Calories manually. It allows it, sort of. But you have to do some playing around. ALL, I REPEAT ALL, Fitness trackers are horrible at recording Weight Training and Static Exercise Machines (treadmills). BUT jawbone does better than all to help the user put the actually calories that they think may have burned and sync with MyFitnessPal.

    2. Sleep tracking: Another good one. Their sleep tracking and integration was awesome and provided me an insight into how I sleep. I noticed that I do my heavy sleeping early and light sleep as the night wears on. I think that is military training. I digress.

    3. Battery Life: 7 days is great. Before I decided to switch, my plan was to wear the device Monday-Saturday and take it off on Sundays for charging. I personally believe that too much tracking and syncing will derail your fitness plans. Need to give it a rest. No matter. This is still a plus.

    4. Ease of use. Very easy to remove and expands. This was useful for weight training when I had to put on my gloves (w/ wrist support). My Fuelband, I must replace the links.

    5. The Silent wakeup. Great idea. TOO bad the Nike FB DOES NOT have this feature ?.

    Cons: Ultimately, I decided I had to return this product because it did not integrate into my routine smooth enough

    1. Software: Jawbone needs to have a desktop app.

    2. Feels Cumbersome: I could never find the right position to wear this thing around my wrist. I initially have the thicker piece facing up. Then I switched to it being down. Jawbone needs to be on board and design the next Up24 as something you strap to your wrist, not wrap around. This was the main reason (if not, the only) I returned the product.

    3. Need to allow the user to manually input his/her calories burned after a workout. Why does Jawbone care if people cheat. They are only cheating themselves.

    4. Need to thin it out. It is too thick and gets in the way. It came off while I was sleep. I believe it's too easy to lose this item. Por Que $150 es mucho dinero (Because $150 is a lot of money).

    5. Where the heck is the heart rate monitor? If it's too much to put into the product, an idea would be to team up with a popular heart rate tracking company to integrate a HR monitor to link in with the UP to give accurate calories burned. Just a thought.
    If Jawbone Up was similar in design to Nike FB SE, I would return the Nike FB SE in a heartbeat.
