CONCLUSIONS: Workers with high physical work demands during early life experience higher intensity of LBP later in life in an exposure–response manner. This finding was observed among currently employed sedentary workers aged ≥50 years, which indicates that early work exposure may matter for musculoskeletal health in later working years. This underscores the importance of careful introduction and instruction to the labour market for retaining musculoskeletal health and prolonging working life.
