How Do Portable Devices Enhance Data Collection?

Portable devices streamline data collection by allowing epidemiologists to gather information directly from individuals in their natural environments. This reduces the reliance on self-reported data, which can be prone to recall bias and inaccuracies. For instance, wearable devices can continuously monitor physical activity levels, providing objective and precise data that can be used to study the relationship between physical activity and various health outcomes.
