O-074 COMBINATIONS OF LOW CARDIORESPIRATORY FITNESS AND HIGH PHYSICAL WORKLOAD AND THE RISK OF DISABILITY PENSIONS DUE TO MUSCULOSKELETAL DISORDERS

Description
Summary:Abstract Introduction The aim of this study was to investigate the combined effect of low cardiorespiratory fitness and high physical workload on disability pension (DP) due to musculoskeletal disorders (MSD: s). Methods 279 353 men were followed regarding MSD DP between 2006-2020, ages 45-64 at the start of follow up. Cardiorespiratory fitness was assessed during military conscription, using an ergometer bicycle test, and physical workload was based on a job-exposure matrix (JEM) linked to occupational titles in 2005. DP cases were taken from register data. Cox regression models estimated the combined association with MSD DP. Results Workers with the combination of the highest level of physical workload and the lowest level of cardiorespiratory fitness showed the highest risk (HR 6.21 95% CI 4.93-7.83); higher than would be expected from adding the effects of the single exposures After adjustment for age, birth year, childhood socioeconomic position, cognitive ability, body mass index, previous unemployment, and education (fully adjusted model), the association attenuated but remained statistically significant (HR 2.39 95% CI 1.87-3.07). Discussion Preventive measures targeting both increased cardiorespiratory fitness and a reduced physical workload could help reduce the risk of MSD DP. Conclusion The combination of low cardiorespiratory fitness and high physical workload was associated with a higher risk of MSD DP than would be expected from adding the effects of the single exposures.
