Objective Low back pain (LBP) is a major problem in modern society and it is important to study possible risk factors for this disorder. People with diabetes are often affected by LBP, but whether diabetes represents a risk factor for LBP has not been studied in detail. The aim of this study was to explore the association between diabetes and subsequent risk of chronic LBP.
Design An 11-year follow-up study.
Setting The Nord-Trøndelag Health Study (HUNT2; 1995–1997) and HUNT3 (2006–2008) surveys of Nord-Trøndelag County in Norway.
Main outcome measure Chronic LBP, defined as LBP persisting at least 3 months continuously during the last year.
Participants A total of 18 972 persons without chronic LBP at baseline in HUNT2, and 6802 persons who reported chronic LBP at baseline in HUNT2.
Methods Associations between diabetes and risk of chronic LBP among individuals aged 30–69 years were examined by generalised linear modelling.
Results Men without chronic LBP at baseline showed a significant association between diabetes and risk of chronic LBP (relative risk (RR) 1.43, 95% CI 1.04 to 1.96, p=0.043). In women, no association was found (RR 1.01, 95% CI 0.69 to 1.48, p=0.98). No association could be established between diabetes and recurrence or persistence of chronic LBP after 11 years in either sex.
Conclusions Men with a diagnosis of diabetes may have a higher risk of subsequently experiencing chronic LBP.
