Many administrative workers are exposed daily to long hours of work in a prolonged sitting position, which can favour the onset of diabetes. The aim of the study was to determine the prevalence and factors associated with diabetes among workers at a town hall in Benin in 2019. Methods: This was a descriptive cross-sectional study conducted from December 2018 to January 2019. Exhaustive recruitment was carried out. Data were collected during a face-to-face interview, using a standardized questionnaire including socio-professional factors, behavioral factors, anthropometric measurements, and blood glucose. Frequencies were calculated. Frequencies were compared using the chi-square and Fisher tests. The significance threshold was 5%. Results: A total of 85 workers were included. Their mean age was 41.55 ± 9.82 years, with a sex ratio of 6.1. = The prevalence of diabetes was estimated at 8.2% [95% CI: 3.38 - 16.23%] and 3 of the workers knew they had diabetes. A family history of diabetes was associated with diabetes (p = 0.032). Occupationally, 10.77% of permanent employees had diabetes, compared with 0.0% of non-permanent employees;12.50% of employees with at least 10 years’ seniority had diabetes, compared with 7.25% of those with less seniority;19.05% of employees who spent at least 6 hours a day sitting at work had diabetes, compared with 4.69% of those who spent less time sitting. Conclusion: Preventing chronic disease in the workplace is part of promoting workers’ health, and must take into account occupational factors such as prolonged sitting.展开更多
