Recent analyses estimate that physical inactivity contributes to 5.3 million deaths per year worldwide and that it is responsible for a worldwide economic burden of $67.5 billion through health-care expenditure and productivity losses. People who are physically active tend to live longer, have lower risk for heart disease, stroke, Type 2 diabetes, depression, and some cancers, and are more likely to maintain a healthy weight ( e.g., ). Physical activity is critical to human health. Mobile apps combining game play with physical activity lead to substantial activity increases, and in contrast to many existing interventions and mobile health apps, have the potential to reach activity-poor populations. Pokémon Go was able to sustain the engagement of its current user base, the game could have a measurable effect on life expectancy, adding an estimated 2.825 million years of additional lifetime to its US users alone.
While challenges remain in sustaining engagement of users over the long-term, if In particular, we find that Pokémon Go is able to reach low activity populations while all four leading mobile health apps studied in this work largely draw from an already very active population. Furthermore, Pokémon Go has been able to increase physical activity across men and women of all ages, weight status, and prior activity levels showing this form of game leads to increases in physical activity with significant implications for public health. In the short time span of the study, we estimate that Pokémon Go has added a total of 144 billion steps to US physical activity. We find that Pokémon Go leads to significant increases in physical activity over a period of 30 days, with particularly engaged users ( i.e., those making multiple search queries for details about game usage) increasing their activity by 1,473 steps a day on average, a more than 25% increase compared to their prior activity level ( p < 10 − 15). Pokémon Go players are identified through search engine queries and activity is measured through accelerometry. We study the effect of Pokémon Go on physical activity through a combination of signals from large-scale corpora of wearable sensor data and search engine logs for 32 thousand users over a period of three months. Quantify the impact of Pokémon Go on physical activity. The most recent and salient example of such a game is Pokémon Go, which has reportedly reached tens of millions of users in the US and worldwide. While many interventions are found to be ineffective at increasing physical activity or reaching inactive populations, there have been anecdotal reports of increased physical activity due to novel mobile games that embed game play in the physical world. Although this knowledge is widely recognized, adults and children in many countries around the world do not get recommended amounts of physical activity. Physical activity helps people maintain a healthy weight and reduces the risk for several chronic diseases.
