Every single hour of television watched after the age of 25 reduces the viewer’s life expectancy by 22 minutes

By comparison, smoking a single cigarette reduces life expectancy by about 11 minutes.

An adult who spends an average of six hours a day watching TV over the course of a lifetime can expect to live 4.8 years fewer than a person who does not watch TV.

Comments from Twitter and Google Plus:

Humera Naqvi, MD @nayab78: hmmm that means we ppl should be dying early taking the amount of tv watched but life expectancy has increased.

K Dillon, RDMS,CPC-A @comalliwrites: Confounders & confirmation bias not accounted for...

@ShadolooDoll: Misleading. It isn't TV itself, but the lack of activity. A person who is dedicated to exercise can still watch TV, right?

Timothy Cook: Great, since I stopped watching TV.  I can start smoking again!  ;-)

Davíð Þórisson: Phew - no mention of watching Youtube! :-)

Jimena Yosara Aguilar Jimenez: I'll never watch tv again

Dimiter Stanev: Does that mean that disabled people suffer from this too?

The Lancet: Commonest cause of maternal death is post-partum haemorrhage - one woman dies every 7 minutes

99% of all deaths in childbirth are in the least developed countries - 45 million women deliver without a skilled birth attendant every year, a situation in which the greatest number of maternal deaths occur.

The commonest single cause of maternal death is from post-partum haemorrhage, from which one woman dies every 7 minutes.

30 minutes is not enough - middle-aged need full hour of exercise to avoid gaining weight as they age

Prticipation in sport is associated with a with a 20—40% reduction in all-cause mortality compared with non-participation. Exercise might also be considered as a fifth vital sign, according to the Lancet: http://goo.gl/gyxYf

Middle-aged women need to get at least an hour a day of moderate exercise if they hope to ward off the creep of extra pounds that comes with aging.

According to JAMA, among women consuming a usual diet, physical activity was associated with less weight gain only among women whose BMI was lower than 25. Women successful in maintaining normal weight and gaining fewer than 2.3 kg over 13 years averaged approximately 60 minutes a day of moderate-intensity activity throughout the study.

Already, two-thirds of U.S. adults and nearly one in three children are overweight or obese.

Sheila Anderson, 50, works out at the fitness center three to four times a week, doing 45 minutes of cardiovascular training and a couple of hours a week of weight training.

"Does it strike me as too much?" she said of the finding. "Maybe. It sure is hard to fit in an hour each day. I could not come to the gym seven days a week," she said.

One hour per day of exercise is difficult to achieve. However, even 30 minutes is better than no exercise at all.



Dr. Michael Roizen, Cleveland Clinic Chief Wellness Officer, answers the question "How much exercise is enough?"

Three parts of exercise have been shown to be beneficial to health:

1. Moving the equivalent to 10,000 steps a day.
2. Resistance exercise for 30 minutes a week.
3. 20 minutes of cardiovascular exercise.

For doctors: How to be a Twitter superstar in 2 easy steps and 30 minutes per day

Warning: The purpose of this article is to inspire you to use Twitter, not to scare you. There are plenty of other blog posts and newspaper articles about doctors posting pictures of body parts on Facebook and getting fired. This is not it. Social media is amazingly useful for doctors and patients if you use the tools responsibly, have common sense, and never share the 18 HIPAA identifiers online or offline with unauthorized parties. The advice below is derived from extensive personal experience. I have used social media for professional purposes, as a physician, for more than 7 years, while working at some of the leading institutions in the U.S. such as the Cleveland Clinic and the University of Chicago. My account @DrVes was ranked #6 on the list of the Most Influential People from Chicago on Twitter (selected by Chicago Tribune and Klout.com). My blog websites have had more than 8 million page views. Just as an example, every time I hit the "publish" button of the sites, the message reaches more than 30,000 people every single day: 17,000 RSS and email subscribers, 9,000 Twitter followers, 3,000 daily visitors, and 1,500 Facebook fans (statistics for the sites ClinicalCases.org and CasesBlog, AllergyCases.org and AllergyNotes, and the Twitter accounts @DrVes and @Allergy).

This is somewhat of a typical example nowadays. There are many other physicians who are much more popular than me on social media and make the stats above look minuscule. You can be one of them. Here is how.

The basics of Twitter use for busy doctors

Most doctors are really busy. Several questions always come up when doctors consider the use of social media for professional purposes: Who has time for Twitter? What am I going to say there? To whom? And why Twitter, to begin with? What about Facebook or YouTube? My office is a mess and I always say "ehhh" when recorded -- I don't want to do video. Do I need a blog too?

Good questions. Here are the answers.

The circle of online information for me is as follows: Google Reader -> Share on Twitter -> Get feedback -> Write a blog post -> Share via RSS and Twitter -> Get feedback, go on. You don't need to use all services.

Here is how to facilitate the Rise of the ePhysican who works hand in hand with the ePatient:



1. Who has time for Twitter?

You do. Twitter should take no more 30 minutes per day and it will be beneficial for you, your colleagues and your patients. You will learn more and will feel better about it. Make it part of your normal routine - just like checking the news. In fact, Twitter is just that - checking the news - and then sharing the ones that you find most interesting with your followers. This takes a single click, and 2 seconds. Ten tweets per day, 2 seconds each. This is 20 seconds. You can do it.

2. Why Twitter?

Start on Twitter because it is quick and relatively easy. Twitter has the lowest barrier to entry among all social media services. "Being on Twitter" requires just 10 short sentences per day, with approximately 7 words each. You can reach thousands of people with a single sentence. Would you like to share the latest guidelines for food allergy? Just click and all your Twitter followers will know about them instantly. You will also get feedback to your tweets via replies and re-tweets.

3. What am I going to say on Twitter?

The answer is simple. You are an expert. There is a flood of medical news that hits the wires every day. I want to know what YOU think is important. Share the 3-10 news items per day that you find interesting. I will subscribe to read them. Many will do the same.

4. Who is going to read my tweets?

As a physician, you are an expert in your field. You provide valuable insight - just be selecting what you think it’s important from the news of the day. Embed this little personal news stream in your practice page. Your patients will appreciate the helpful updates, hand-picked by their doctor. Your colleagues may find it interesting too.

5. What about Facebook or YouTube?

Those are nice but I would start on Twitter first, and then expand if you see the need to do so. It may be a good idea to start a like/fan page on Facebook for your practice and re-post some of the tweets there. This is simple and not time-consuming. It can be done automatically.

6. Do I need a blog too?

Only you can tell if you need a blog. If you feel that you need to expand beyond 7-8 words on Twitter, by all means, start a free blog on Blogger.com by Google or WordPress.com and see how that works for you. Start on Twitter and expand to a blog as a natural extension if you need to write longer or provide some background. Post your blog items in your Twitter feed.

How to be a Twitter "star" in two easy steps

This is easy. It’s a two-step process for beginners and it takes about 30 minutes per day. The best time is just after your kids go to sleep.

1. Review the news of the day from Google Reader. I have ready-made subscription RSS bundles for you below. Alternatively, you can check a service such as Webicina.com for RSS feeds in your specialty.

2. Post the news items that you like best on Twitter. Don’t post all 10 tweets at once. Schedule them evenly throughout the next day. The first tweet goes on at 7:30 am EST and the last one at 8:30 pm EST. You can use Seesmic Web to schedule tweets - it is simple, free, and just works. The alternatives include HootSuite and any number of scheduling services (some of them have a limitation of up to 10 tweets per day).

This summary did no address the other Twitter activities such as listening, engaging, search, chat, HIPAA compliance, etc. They will be discussed in future articles.

RSS bundles of medical news

You can use the following RSS bundles to subscribe to medical news items. The bundles are exported from my personal Google Reader page. They update automatically several times per day. When in Google Reader, just select the ones that you find interesting and share them on Twitter. Feel free to add your own comments to some of the tweets.
