Studies show that Fitbit is making an impact
on health and wellbeing.
For decades, medical research has proven that healthy lifestyle behaviors such as regular physical activity, sufficient sleep, a well-balanced diet, and stress management can have a tremendous impact on our health and longevity. Walking has been shown to reduce hypertension, diabetes and high cholesterol¹. A good night’s sleep helps maintain a healthy weight and improves mental health². A healthy diet can prevent cardiovascular disease³. Lower stress levels can mean lower blood pressure⁴. The science is plentiful, and very encouraging: it means you can help your population take control of their health, and help reduce the healthcare costs associated with many chronic conditions.
Poor sleep is associated with significantly higher rates of healthcare utilization, adding $94.9 billion in costs each year to the US healthcare system⁵
The estimated global direct health expenditure on diabetes is expected to grow to $825 billion by 2030 and $845 billion by 2045⁶
Lack of physical activity
is linked to approx. $117 billion in annual US healthcare costs⁷
We’re proud to say that Fitbit has played a critical role in health and wellness research, powering over 1,700 studies and interventions across a dozen focus areas. Many of these studies have demonstrated that adding the Fitbit experience, including a Fitbit tracker or smartwatch and the Fitbit app, to existing health and wellness interventions can help improve outcomes.
Select Study Type
3rd Party Studies
Health2Sync, the leading diabetes management app in Taiwan and Japan, conducted a clinical trial to determine the impact of Fitbit intervention on people with diabetes.
average decrease in HbAlc
average decrease in blood glucose
average decrease in LDL cholesterol
The National Institutes of Health’s research program All of Us conducted one of the longest and largest studies of its kind to examine associations between physical activity over time and rates of chronic disease. The study included 6,000 participants who measured their activity with Fitbit devices.
25% reduced risk
of type 2 diabetes with each increase of 1,000 steps in participants’ average daily step count
44% reduced risk
of type 2 diabetes among participants who took over 10,000 steps a day
Those who maintained over 10,000 steps a day also saw reductions in obesity (-41%) depression (-33%), gastroesophageal reflux disease (-36%), high blood pressure (-25%), and sleep apnea (-46%).
37 randomized controlled trials of interventions related to healthy lifestyles with groups that used Fitbit and groups that did not.
more steps per day
more minutes of activity per day
more pounds of weight loss
Fitbit User Analysis
Here at Fitbit, we offer our users the opportunity to participate in our own research.
Analysis to determine if users who engaged with Fitbit more saw improvements in their health above users who engaged less, using anonymous, aggregated consenting user data; users used Fitbit in different ways and at different frequencies.
Improved Stress Management & Better Sleep Score
These results seen through 6 x 6-minute sessions of relaxation & mindfulness activities over 5 days and 4 EDA sessions over 28 days
Lower Resting Heart Rate
This results seen through 1 EDA session, 2-minute guided breathing, listening to meditation audio
Analysis to determine whether hitting the American Heart Association’s recommended physical activity target of 150 minutes per week of moderate intensity aerobic activity leads to measurable improvements in Fitbit users.
Those who met activity goals of 10,000 steps per day and 150 Active Zone Minutes per week for just 2 weeks saw:
higher heart rate variability
lower resting heart rate
management & sleep score
by 3.4% and 4.2%
AFib & The Fitbit Heart Study
Atrial Fibrillation (AFib) is the most common type of irregular heart rhythm, and is associated with a 5x risk of stroke. The incidence and prevalence of AFib is on the rise, affecting 33.5 million people around the world. Wearable devices have been shown to be an effective early-detection tool, and can help reach more people who may otherwise not have access to detection.
To help reduce the impact of AFib, we launched the Fitbit Heart Study, our first large-scale, virtual study to validate the use of our wearable technology to identify episodes of irregular heart rhythm suggestive of AFib.
Positive Predictive Value (similar across males and females)
Positive Predictive Value (for participants over 65)
“My hope is that advancing research on innovative and accessible technology, like Fitbit devices, will lead to more tools that help improve health outcomes and reduce the impact of AFib on a large scale.”
