Physical Inactivity-Related Cancers
This is a predefined variable created using ICD-O-3 site, histology, and sex to define physical inactivity-related cancers.1 2
Considerations for Use
- Cancer registries do not routinely collect data on physical inactivity, so the number of cancers associated with this risk factor cannot be determined definitively.2 3 4
- However, other sources of information can be used to obtain the proportion of cancers probably caused by the risk factor, known as the attributable fraction.5 The number of attributable cancers can be estimated by multiplying the attributable fraction by the number of associated cancers.
- For more information, please see the referenced publications and Predefined Variables for Risk Factor-Associated Cancers documentation.
- Please note that in official federal cancer statistics publications, CDC reports malignant (invasive) cancers except for bladder cancers (includes in situ and invasive cancers).
