Health Apps Could Be Doing More Harm Than Good, Warn Scientists (theguardian.com) 93

According to several scientists, fitness apps might be doing more harm than good because they don't work but force people to focus on ambitious goals that they will never reach. Some are so appalled by these apps that they have called it "snake oil salesmen of the 1860s." From a report on The Guardian: Greg Hager, professor of computer science at Johns Hopkins University, said that in the absence of trials or scientific grounding it was impossible to say whether apps were having the intended effect. "I am sure that these apps are causing problems," he told the American Association for the Advancement of Science annual meeting in Boston. [...] Hager claimed the 10,000 steps target dated back to a 1960s Japanese study that showed there were health benefits for men who burned at least 2,000 calories per week through exercise -- roughly equivalent to 10,000 steps each day. An early pedometer was known as the manpo-kei, which means "10,000-step meter" in Japanese. "But is that the right number for any of you in this room?" Hager asked. "Who knows. It's just a number that's now built into the apps." "We have an incredible number of apps in the wild basically being downloaded by people who may or may not understand what they are actually telling them or what the context for that is," he said. "Until we have evidence-based apps you could amplify issues. I mean, imagine everyone thinks they have to do 10,000 steps but you are not actually physically capable of doing that, you could actually cause harm or damage by doing so."

    Without scientific study we can't say for sure that these apps are working, but we can say for sure that they're causing problems... Makes sense. As to pushing someone to walk 10,000 steps per day, if a person's not physically capable of walking 10,000 steps it's on them and their doctor to determine that. No app is going to force me to do something I'm not capable of just because it says on the screen that I should.

      If your liver is not working right, and an app advises you to eat certain amounts of certain foods, you won't know you were not capable of eating those foods until your doctor is telling you you have only 4 days to live unless you luck into a liver transplant.

      You're right though, the claim "I'm sure they are doing harm" would require some evidence.

        If your doctor hasn't already told you not to eat certain foods because of your liver, how does the app have any more probability of harming you than your own subjectively selected diet? If the doctor has warned you but you weren't listening, then how is the app any more likely to be harmful than your own subjectively selected diet?

          A lot of people don't have any individual to call "my doctor" and an app may ask you to do unusual things or things that push you past limits that you are unaware of.

I haven't seen anything that would be dangerous unless you're seriously out of shape or suffer from some extreme affliction. Considering how lawsuit happy people are, I doubt any of these apps are recommending anything dangerous to 99.99999% of the public.

        You'd KNOW you were sick LOOOONG before you had 4 days left. In most cases, your liver would be enlarged due to inflammation (aka hepatitis) at the very least, which would be quite painful and you'd notice, but you'd still be a ways off from liver failure (and indeed your liver is resilient enough to recover from this point so long as you eliminate whatever is causing it harm.)

        Let me help you with that. The science has been settled on that study long ago. Exercise and movement = good. It's right up there with the climate is changing, gravity exists, and the air is breathable. There's not been a single scientific study that says exercise and movement is bad and it isn't back by any medical principles either.

        Now the amount of benefit will likely vary but that's not what was being discussed, what was being discussed is that health apps come with a default setting and that setting is bad and we need science to determine a solution to suit everyone. That, my friend, is absurd.

        Also answering whether having an app tell you to get off your ass actually does get you off your ass will vary greatly.

        Science can not help you there. But having the app certainly doesn't produce a negative result there either, and if you are really contrarian you probably wouldn't have the app in the first place.

              I wouldn't argue that point. However, they're already doing it-- my major carrier employer healthcare plan for example, offers a discount if you buy a FitBit and meet certain goals with it. Goals that, according to some fellow employees who've attempted to meet them, are next to impossible to achieve. No one ever said it was going to be "sane."

      To cut to the core of what I'm saying here: Many people see that number, see they NEVER meet it, and feel LESS motivated. People don't like failure--even if it's just a lack of "star" icon appearing on their app to remind them of their perceived failure.

    It's worse that being built into a crappy little "health app" - it can actually cost you hundreds of dollars a month.

    I was recently at a company where you got a discount on your health care plan if you walked 3,500 steps a day. With that in mind, I downloaded the related health-care app so I could reverse-engineer the web services and feed them the appropriate numbers each day to avoid paying more.

      I want you to define what apps need science behind them. Based on the universal concensus of exercise / movement / not sitting on your fat arse at the TV all day = good for you I would say every single fitness app has science behind it.

      The actual science itself is already done. Most fitness apps that I've seen ask for weight, and age, and then use generally medically accepted figures to determine target heart rates for exercise etc. Every other fitness app is nothing more than a tracker and is completely at the control of the person using it: i.e. no science needed by the developer. They don't care if you run 1km or 5km.

      Quite frankly the entire premise of science hasn't determined a one size fits all approach so you shouldn't use apps is simply stupid.

Science does support exercise being vastly beneficial, and all the 10,000 steps really amounts to is an admonition to move more than most people probably do already.
