German National Cohort (NAKO) Level 3 Project SWEAT-DE Study


Smartphone- & Wearable-based Activity Trackers – Determinants of Engagement

We are pleased to introduce the SWEAT-DE Study, a research project dedicated to exploring the influence of smartphone and wearable-based activity trackers on health behavior among adults in Germany.


Project Description:

In recent years, there has been a noteworthy increase in the popularity and availability of activity trackers. They are smart devices that can monitor your physical activity levels and provide personalized feedback. These devices, typically in the form of smartphones or wearable gadgets, combine sensors and algorithms to capture and quantify various aspects of movement, such as the number of steps you take, the distance you travel, calories burned, and even your sleep patterns.

Our study specifically focuses on smartphone and wearable-based activity trackers and how they can impact health behavior changes among adults in Germany. We want to understand how people use these devices, what motivates them to engage with the technology, and how it affects their health and lifestyle choices.

Conducted by the Leibniz Institute for Prevention Research and Epidemiology – BIPS, the study uses a web-based questionnaire integrated into the NAKO Health Study. The questionnaire will cover topics related to participants' personal experiences with activity trackers, as well as their motivation and attitudes towards using these devices.

The findings from the SWEAT-DE Study have the potential to inform various stakeholders, including public health professionals, app developers, and health service providers. By enhancing our understanding of how these trackers influence behavior, we can work towards improving digital interventions and encouraging greater adoption and engagement with such technologies.
