The affluent tend to use popular mobile phone apps that track sleep habits more than those who actually need to track their sleep.
These are some of the surprise findings, say the study authors, of the first national survey of sleep-specific mobile health app use among men and women in the United States.
The research team says that the widespread use of mobile devices to monitor daily habits may offer healthcare providers a way to more quickly diagnose and more effectively treat sleep problems, which are tied to increased rates of heart disease, cancer, and diabetes.
Sleep App Users
But the NYU School of Medicine research team cautions that the value of sleep apps to either users or sleep specialists is unclear so far. They say the current study sets the stage for future investigations to determine what aspects of sleep can be measured effectively by the apps, and how these measurements can be used to gauge changes, both good and bad, in sleep patterns.
"People are getting all this information on their sleep patterns and not really knowing how to interpret it, or even if it's legitimate data," says study lead investigator, Rebecca Robbins, PhD, a postdoctoral research fellow in the Department of Population Health at NYU Langone Health.
The new study findings are based on results of a survey conducted in June 2015. The survey group comprised an ethnically diverse population of 934 mobile phone users, of whom 263 (28 percent) say they use a health app to keep tabs on how long they sleep, what time they turn out the lights, whether they wake up in the middle of the night, and whether they snore, have trouble breathing, or change sleeping position.
In addition to the overall health and wealth of the majority of users, the results showed that :
- More men than women track their sleep (35 percent versus 20 percent, respectively)
- The average age of those who use sleep apps was 34
- People with yearly incomes above $75,000 and those who already use a health app to remind them about taking their medications were also more likely to track their sleeping habits.
- Sleep app users typically had between 16 and 25 health apps on their smartphones
- The most popular apps for sleep tracking (of 24 health apps identified in the survey) are Fitbit (10 percent), Lose It (3.5 percent), and Apple Health (2.6 percent)
Once validated, says Robbins, sleep apps could become a powerful tool as not just a "health coach," but also as a "sleep coach." Ideally, she hopes that mobile apps will serve as a key tool for monitoring patients between check-ups.
