Occupational lifting predicts hospital admission due to low back pain in a cohort of airport baggage handlers.

Cessation of work as a baggage handler was associated with a decreasing trend in the risk of LBP with time since cessation (HR = 0.72, 95% CI 0.54–0.95, P = 0.02 for every 5 years since cessation) There was an interaction between time since cessation and cumulative years of employment ( P = 0.01), so that the effect decreased more among baggage handlers with 10 years or more of employment than among baggage handlers with less than 10 years of employment.
