This cross-sectional observational study evaluated the prevalence and determinants of metabolic syndrome
(MetS) among 1432 seafarers aboard 76 trade vessels in the Red Sea. Data collection involved onboard examinations and remote or email-based protocols, encompassing anthropometric, biochemical, and lifestyle assessments. The prevalence of MetS was 27.8%, with higher rates among officers (33.5%) than among ratings
(24.8%). Central obesity (81.3%) and elevated blood pressure (72.4%) were the most common components.
Multivariate analysis identified age of 40 years or older, officer rank, and physical inactivity as significant
predictors. Based on these findings, a novel three-phase maritime health framework is proposed, integrating
digital screening, artificial intelligence (AI)-driven risk stratification, and continuous telemedicine monitoring.
This model addresses operational challenges in surveillance compliance and aligns with the shipping sector’s
digital transformation, providing a predictive and preventive approach to chronic disease management at sea.
