A history of prior chronic pain anywhere in the body is the strongest predictor of chronic back pain (CBP), according to a new study, which surveyed 2,184 adults in 1996 and again in 2000.

Overall, 16% of those surveyed reported CBP in 1996. This prevalence had grown to 27% in 2000.

Results revealed that "factors in 1996 independently associated with persistent compared with recovered CBP were preexisting arthritis, high [Level of Expressed Need (LEN)], poor mental health and not living alone. Factors independently predicting new CBP compared with no previous CBP were previous chronic pain elsewhere and poor physical health. Persistent CBP was associated with more severe pain, higher LEN, and poorer general health than new CBP."

"CBP is a common and lasting problem, whose persistence and onset are predicted by clinical (especially pain) and help-seeking behavior factors, rather than socio-demographic. Prevention should focus on these factors," conclude the study's authors.
