Therefore, it is advisable for people to use discretion when considering Fitbit measurements and not rely on them to inform healthcare decisions. The researchers identified a vulnerability in Fitbit software that may make users’ data easier to access or change by malicious third-party applications on the Fitbit. One 2018 study notes that although Fitbits are a useful tool for motivating people to become more active, their measurements are not always entirely accurate.Ī 2019 study concluded that Fitbits were not as accurate as medical-grade devices, and users should also be aware of potential data security risks. It is worth mentioning that some studies have shown that not all Fitbit measurements are 100% accurate. This study included 51 postmenopausal women and found that participants with a Fitbit increased their overall physical activity and number of steps each week compared with participants using standard pedometers. Therefore, tracking steps may encourage a person to walk more.Īnother 2015 study showed that Fitbits could motivate people to exercise more frequently. In the study, older adults who took part in a 12-week walking program with a pedometer were less likely to experience heart problems and fractures than the control group. This finding builds on evidence from a 2015 study, which showed that regular walking was associated with decreased mortality for males aged 65–74 years.Ī 2019 study found that the use of pedometers - a device that tracks a person’s daily steps, similar to a Fitbit - can positively affect a person’s health. Walking regularly can have positive effects on a person’s fitness and general health.Ī 2020 study suggests that adults who take 8,000 or more steps each day have a lower risk of death from numerous diseases than those who take fewer than 4,000 steps each day. Some people find that Fitbits help motivate them to walk more regularly.
