IntroductionNight work and shift work are part of the so-called ‘atypical’ working hours. Due to their specificities, they can be risk factors for workers’ health as well as aggravating factors for certain pathologies.AimsTo study the impact of chronic pathologies on the medical aptitude of patients for NPT.MethodsRetrospective descriptive study of patients with chronic pathologies who consulted the Occupational Medicine Department at Charles Nicolle Hospital over a six-year period from January 2016 to June 2022 and who benefited from an eviction from work with atypical hours.ResultsAmong 224 employees working non-standard hours, 52.6% (n=118) had chronic pathologies. The average age was 43.32±8.64 years. The sex ratio (M/F) was 1.62. The average professional seniority was 18.06±10.48 years. The most represented sectors were health (38%), transport (10%), food industry (7%) and automotive industry (6%). The most common occupations were manual workers (26%), drivers (12%), security guards (11%) and senior technicians (12%). The most common chronic pathologies were insulin-dependent diabetes (20%), epilepsy (18%), poorly controlled arterial hypertension (6%), myocardial infarction (5%), multiple sclerosis (4%), breast cancer (3.5%) and sleep apnoea hypopnoea syndrome (3%). Concerning the medical aptitude to work of the patients, a definitive avoidance of shift/night work was indicated in 91% of the cases.ConclusionAccording to our study, several chronic pathologies contraindicate working atypical hours. The role of the occupational physician is to evaluate the risk for each pathology.
