Abstract
Methods Municipal employees aged 44–58 years were studied in 1981 (n=6257) with follow-ups in 1985, 1992, 1997 and 2009. Pain in the neck, low back, and upper and lower limbs was assessed in each survey. Trajectories of the number (0–4) of pain sites were defined using growth mixture modelling (n=3093). Workload, lifestyle and morbidity were elicited by questionnaire and retirement from registries. Associations of baseline factors with pain trajectories were assessed by multinomial logistic regression. Cumulative hazard curves for retirement by trajectory group were calculated.
Results Three trajectories of pain over 28 years emerged: low (25%), moderate (52%) and high-decreasing (23%). In the latter, the number of pain sites first decreased sharply, stabilising to a moderate level after most subjects had retired. The disability pension rate was highest in this trajectory, which associated with high baseline morbidity, particularly musculoskeletal disorder (OR 8.06; 95% CI 5.97 to 10.87). Also high biomechanical exposure (2.86;95% CI 2.16 to 3.78), high job demands (1.79; 95% CI 1.39 to 2.30), high job control (OR 0.70; 95% CI 0.54 to 0.90), body mass index (BMI) ≥25.0 kg/m2 (1.40; 95% CI 1.09 to 1.80) and low leisure-time physical activity (LTPA) (1.39; 95% CI 1.09 to 1.78) at baseline were associated with this trajectory. However, high LTPA and BMI in repeated surveys also associated with the high-decreasing trajectory.
Conclusion MSP in midlife often persists to old age. However, high widespreadness of pain may decrease with retirement from work.
