[Pre-surgical period and non-work-related sickness absence due to inguinal hernia].

Background And Objective: To analyze non-work-related sickness absence (NWR-SA) due to inguinal hernia and the factors related to its duration, paying particular attention to the pre-surgical period of NWR-SA.

Material And Methods: Prospective cohort study was conducted on 1,003 workers with an episode of NWR-SA due to an inguinal hernia, belonging to the insured population of a mutual insurance company. We assessed the duration of the NWR-SA episodes and the main demographic, occupational and clinical variables potentially related to it.
