In the 2007 NHIS on-line analysis system why does the variable "comtbnpain" only code for children

#1

I was interested in examining the age distributions of the use of acupuncture, chiropractic and massage therapy for backpain. When I used the following variables (below) in the on-line analysis system for 2007 data, only children (4-17) used chirorpatic for backpain which is clearly incorrect. Any thoughts?

| Row | comtbnpain | Used chiropractor for: Back or neck pain | 0-2 | | 1 |
| Column | age | Age | 0-85 | | 1 |
| Weight | sampweight | Sample Person Weight |

The back pain variable that you used, COMTBNPAIN, is specific to sample children. For sample adults, you should use the back pain variable COMTBACPAIN.

Hope this helps.

Thanks. I would suggest that on the on-line system variable list you specify which are for children and which are for adults and which are for both,
