Smoking expands expected lifetime with musculoskeletal disease regardless of educational level.

Lifetime with musculoskeletal disease were estimated for never smokers and smokers at three educational levels. Expected lifetime with musculoskeletal disease was 7.4 and 10.6 years for 30-year-old men and women, respectively. Regardless of educational level smokers could expect more years with the diseases than never smokers. Thus, the impact of smoking on the burden of musculoskeletal diseases is not confounded by educational level.
