Description

For sample adults aged 40 years or older who had not had a colonoscopy in the past 10 years, sigmoidoscopy in the past 5 years, CT colonography in the past 5 years, or home blood stool test in the last year, COLTDR1YR indicates whether, in the past 12 months, a physician or other health professional recommended testing to look for problems in their colon or rectum.

If respondents indicate that a health professional recommended additional testing for problems in their colon or rectum, the following variables report which tests had been recommended:

  • COLCANBST: Doctor recommended blood stool test to check for colon cancer
  • COLCANCOLG: Doctor recommended Cologuard/FIT DNA test to check for colon cancer
  • COLCANCOLCT: Doctor recommended CT colonoscopy to check for colon cancer
  • COLCANSIG: Doctor recommended sigmoidoscopy to check for colon cancer
  • COLCANCOL: Doctor recommended colonoscopy to check for colon cancer
  • COLCANOTH: Doctor recommended other test to check for colon cancer
 

According to the 2010 and forward Field Representative's Manual, this and related questions were asked:

...to determine the practices and knowledge of the public with regard to cancer screening practices. This includes practices that are known to reduce mortality from cancer and some for which evidence of effectiveness is not available. The 2010 Cancer Screening Supplement will be the first time questions about having a breast MRI, virtual colonoscopy, and lung x-ray are in the NHIS.

The Manual in 2010 and forward further provided the following definition for cancer:

A term for diseases in which abnormal cells divide without control. Cancer cells can invade nearby tissue and can spread through the bloodstream and lymphatic system to other parts of the body.

The Manual in 2010 and forward also provided the following statement regarding how the data from the Cancer Screening questions would be used:

. . . It also allows for comparisons among subgroups of the population to examine factors that may influence . . . cancer screening exam practices. Together, this information will be useful in developing public health and health services programs to increase . . . the use of regular and effective screening.

Comparability

Aside from a slight change to the universe introduced in 2018, there are no comparability issues. Before 2018, this variable was collected for sample adults 40 and older who had not had a colonoscopy in the past 10 years, sigmoidoscopy in the past 5 years, CT colonography in the past 5 years, or home blood stool test in the last year. Beginning in 2018, it was collected for the same group of adults with the additional qualification: "or home blood stool test in the last year (including Cologuard)."
