Abstract

Objectives: To investigate health-related and sociodemographic risk factors for disability pensions (DP) due to low back disorders (LBD).

Methods: Questionnaire data in 1975 of the Finnish Twin Cohort Study with record linkage to information on DP due to LBD from the official pension registers during follow-up 1975 to 2004 was analyzed with Cox proportional hazard models.

Results: Musculoskeletal pain (Hazards Ratio [HR] = 2.36 to 2.39; 95% CI 1.97 to 2.88), smoking (HR = 1.82; 1.49 to 2.22), frequent analgesics use (HR = 1.67; 1.38 to 2.02), and presence of other chronic disease (HR = 1.44; 1.22 to 1.70) increased the risk for DP due to LBD. Years of education decreased the risk (HR = 0.81; 0.77 to 0.85). Associations remained significant when adjusted for familial background.

Conclusions: Health-related and sociodemographic risk factors for DP due to LBD can be identified early in life, and they seem independent from familial effects.
