Note. OR = odds ratio. Pain was defined as interfering with usual activities fairly often or all the time over the previous 12 months. Survey respondents worked 25 hours per week or more. All estimates were weighted to reflect the population and adjusted for the sampling design.

^aStanding and moving around a fair amount (e.g., from 1 office or building to another).

^bStanding and moving around a little bit (e.g., from 1 machine or desk to another).

^cStanding in a fixed position with no ability to move around or in a relatively fixed position, with the ability to make 1 or 2 steps.

^dSitting in a fixed position with no possibility of getting up and moving around or with the possibility of getting up once in a while.

^eSample size too small for multivariate analyses or too few women exposed.

^fLow psychological demands, high decision latitude.

^gLow psychological demands, low decision latitude.

^hHigh psychological demands, high decision latitude.

ⁱHigh psychological demands, low decision latitude.

*P < .05; **P < .01, for differences between men and women.
