NHANES 2003-2006: Minute-Level Accelerometer Activity Data

NHANES 2003-2006 accelerometer data processed by vandomed provides physical activity metrics derived from wearable devices used in the National Health and Nutrition Examination Survey. Updated in 2020, the repository focuses on converting raw sensor readings into structured data for sedentary-life and exercise analysis.

Use Cases

• Quantifying sedentary-life duration using accelerometer activity counts
• Modeling physical-activity intensity levels from wearable-device sensors
• Analyzing exercise patterns across different NHANES demographic cohorts

Strengths

• Derived from the NHANES 2003-2006 national survey cycles
• Includes wearable-device accelerometer sensor data
• GPL-3.0 licensed for open redistribution

Limitations

• Temporal staleness as data is from the 2003-2006 period
• Metadata lacks specific record counts and column definitions
