Can Your Fitness Tracker Save Your Life?

Fitness trackers and ‘wearables’ are becoming ubiquitous.

Fitness tracker “wearables” have become mainstream, with sales projected to reach $19 billion by 2018. If you don’t have one, many of your patients probably do, particularly this time of year when fitness goals are at the forefront of many New Year’s resolution lists. Wearables can track a lot of things, and people are claiming that they save lives. Are they all that? First, here’s a brief overview of wearables types and their uses.

Popular wearable brands include Fitbit (with 79% of sales), Jawbone, Nike, Apple (Apple Watch is a smart watch that has fitness tracker functionality), Garmin, and Misfit. Prices run from about $50 to as much as you want to spend: an Apple Watch costs from $275 to more than $10,000, depending on the model.

Increased functions. Wearables have far surpassed their pedometer function. They do all count steps, but now they also track sleep and heart rate and have increasingly more bells and whistles. The newer Fitbits and the new watchOS operating system for the Apple Watch even have “breathe” functions, intended to remind the wearer to take a few minutes several times a day and breathe to promote relaxation.

Wearables (including smart watches) now have extra features such as replaceable bands […]

2016: An ‘Unbelievable’ Year

“When I think about 2016, one word that keeps coming to mind is ‘unbelievable.’ It’s a word I’ve found myself using many times over the past year, often while shaking my head in disbelief.”

That’s the opening of AJN editor-in-chief Shawn Kennedy’s January editorial. In it, she lists serious public health challenges facing this country and the ways political considerations get in the way of acting in the public’s best interest—whether in relation to gun violence, funding to fight infectious disease threats, the ever-increasing cost of essential medications, or health care reform. Too often lies and distortions are now treated by people who know better as the equals of truth and fact.

But you probably have your own list of ‘unbelievable’ things that happened in 2016, perhaps some of them hopeful. Click the above link to read the article, which is free.

Metabolic Syndrome: Lifestyle Factors and Prevention

Metabolic syndrome: one-third of U.S. adults.

Cycling Mother and Daughter, Netherlands/via Wikimedia CommonsConversations about health—whether between neighbors or between clinicians and patients—often revolve around weight problems, blood pressure, blood sugar, and cholesterol levels. Taken together, these are the cardiovascular risk factors referred to as metabolic syndrome.

In the United States, more than one-third of all adults have metabolic syndrome. This is an astonishing figure, especially because these risk factors can be modified.

What keeps some who are obese or overweight ‘metabolically healthy’?

In recent years, researchers have learned that some people who are overweight or obese do not demonstrate the other risk factors that are part of metabolic syndrome, and therefore these people have a lower-than-expected risk of cardiovascular disease. In a study reported in this month’s AJN (“Examining the Links Between Lifestyle Factors and Metabolic Syndrome“), a group of Taiwanese nurse researchers set out to learn whether there might be lifestyle factors that keep this subgroup of people “metabolically healthy,” protecting them from the other cardiovascular risk factors that usually come with extra weight.

Lifestyle factors associated with prevention.

Dr. Shu-Hung Chang and colleagues performed community-based physical exams on more than 700 people in northern Taiwan and questioned them about lifestyle factors including smoking, drinking, exercise, and the foods they ate. The researchers […]

A Status Update for World AIDS Day

Photo of AJN editor-in-chief Shawn KennedyIn light of the recent focus on Zika virus and the last few years’ attention to Ebola, there’s been little attention to HIV/AIDS. Today, December 1, World AIDS Day, is a good time to remember that millions still suffer from this disease and thousands contract it annually.

According to the MMWR report released last week by the Centers for Disease Control and Prevention (CDC), the statistics are still sobering:

  • Globally, over 36 million people have AIDS and 2.1 million were newly infected in 2015; 1.1 million died.
  • In the United States in 2013, approximately 1.2 million people had an AIDS diagnosis; approximately 44,000 were newly diagnosed in 2014.

There is good news, in that global access to treatment has increased greatly—in 2010, 7.5 million had access to antiretroviral treatment; by June 2016, over 18 million had access to antiretrovirals.

It’s been over 35 years since AIDS was first reported by the CDC—you can read an overview of the CDC’s response here. I recall the AIDS epidemic only too well. As I wrote in an editorial in 2010:

In 1975, while attending graduate school, I worked part time as a chemotherapy nurse for a hematologist in New York City. Because of his expertise, he was increasingly being asked to consult on cases involving seemingly healthy young men, most of them gay, who […]

Remembering a Tough NYC Detective on the 41st Great American Smokeout

Photo of AJN editor-in-chief Shawn Kennedy AJN editor-in-chief Shawn Kennedy

My uncle Joe embodied the persona of the old-time tough NYC Irish detective—he was over six feet tall, had piercing blue eyes and white hair, always wore a tan raincoat, and always had a cigarette in his hand. As a child, my siblings and I were always a little bit afraid of him. That image faded, though, and my last image of him was hunched over, with an oxygen cannula, trying to breathe. All those cigarettes added up, and after a lifetime of smoking, he died from chronic lung disease. This was before the landmark report on smoking and health issued by the U.S. surgeon general in 1964. Tiffany, 35, Louisiana; quit smoking at 34; smoke-free since January 2012.
