Abstract

Background: Seafarers are at increased risk of diabetes due to their lifestyle and working conditions on board ships. There is, however, limited evidence regarding the magnitude of diabetes and its risk factors. In this study, we aimed to assess the prevalence of self-reported diabetes among seafarers on board ships and identify risk factors associated with it. Materials and methods: A cross-sectional epidemiological survey was conducted among seafarers aboard ships between November and December 2022. The study enrolled a total of 4, 500 seafarers aged 18 and older. Data were collected using anonymous, standardized questionnaires. The association between the outcome variable and the independent variables was assessed using binary logistic regression models. Results: In total, 2, 986 participants were included in the study. The prevalence of self-reported diabetes among seafarers was found to be 8.2% (95% CI: 7.2–9.2). Self-reported diabetes prevalence among officers and non-officers was 7% and 9%, respectively. The mean age of study participants was 37.96 ± 10.22, while the mean age of participants with diabetes was 47.5 ± 9.46. Independent predictors of self-reported diabetes mellitus were age (51+ years) [adjusted odds ratio (AOR): 3.52, 95% confidence interval (CI): 1.46–8.95], rank (non-officer) [AOR: 1.65; 95% CI: 1.14–2.40], worksites (engine) (AOR: 2.08, 95% CI: 1.19–3.77), work experience (10–20 years) (AOR: 4.66, 95% CI: 2.33–10.05), work experience (21+ years) (AOR: 5.01, 95% CI: 2.32–11.55), working hours per week (57–70 hours) (AOR: 1.57, 95% CI: 1.08–2.31), working hours per week (71+ hours) (AOR: 1.80, 95% CI: 1.17–2.80), self-reported hypertension (AOR: 1.44, 95% CI: 1.03–1.99), overweight (AOR: 1.74; 95% CI: 1.24–2.47), and obesity (AOR: 2.93; 95% CI: 1.84–4.65). Conclusions: This study revealed that one in twelve seafarers between the ages of 19 and 70 have self-reported diabetes. The present study identified significant risk factors associated with diabetes. Risk factor mitigation strategies aimed at high-risk groups should be implemented on board ships.
