CPS-3 Accelerometry Sub-Study Tracks Participants’ Daily Activity

Studies have shown that being physically active decreases the risk of various cancers, but much more remains to be learned. On the original CPS-3 Enrollment Survey and on follow-up ones, participants are asked questions about different types of physical activity, sedentary behavior, and sleep.

In the Accelerometry Sub-Study, we are inviting 20,000 randomly selected CPS-3 participants to wear an activity monitor (also called an accelerometer) around their waists for 7 days while they’re awake.

Our CPS-3 team will use the data to study patterns of physical activity and sitting time in a more detailed way, such as whether ‘weekend warriors’—people who work out only on weekends and are sedentary during the work week—gain the same cancer risk-reducing benefits from their physical activity as people who spread out their physical activity throughout the week.

Data gathered from the Accelerometry Sub-Study will help researchers better understand how physical activity and sitting time affect health, and the study findings will be used to advance public health prevention recommendations for cancer and other diseases.
