A descriptive epidemiological study of cardiovascular diseases among seafarers.

BACKGROUND: Cardiovascular diseases (CVD) are the leading cause of morbidity and mortality among seafarers. This study aimed to evaluate CVDs distribution and differences, considering seafarers' rank and worksite groups. MATERIALS AND METHODS: A descriptive epidemiological study was employed, and the analysis was based on the telemedical assistance data of the International Radio Medical Centre (C.I.R.M.) from 2010 to 2018. The age, gender, rank, and worksite variables were considered for the analysis. Chi-square or Fisher test was used to assess differences in CVD distribution between rank and worksite groups. RESULTS: Cardiovascular diseases were the sixth leading cause of medical advice requests to C.I.R.M. Distribution of CVD significantly differed between officers and non-officers [x2 (5) = 17.308, p = 0.004]. Officers were often diagnosed with hypertensive CVD (46%), whereas non-officers were frequently diagnosed with ischaemic heart diseases (41%). There were no significant differences in the distribution of CVD diagnoses between worksite groups [x2 (10) = 12.863, p = 0.231]. CONCLUSIONS: The frequency of CVD is higher among non-officers and older seafarers who have been more often diagnosed with CVD. Specific interventions such as early diagnosis, regular monitoring, and physical training to reduce cardiovascular risk should be considered on board ships. Future studies should take into account the incidence rate of CVD between rank and worksite groups.

Overweight among seafarers working on board merchant ships.

BACKGROUND: Obesity and overweight represent a relevant risk factor for seafarer's health. The frequency and distribution of overweight and obesity among seafarers working on board of Italian flag ships were studied. Analysis was made on occupational medicine files collected, in the frame of health surveillance inspections, between 2013 and 2016 from Centro Internazionale Radio Medico (CIRM). METHODS: The data of nationality, age, weight, height, blood glucose and blood pressure values obtained from 1155 seafarers were analyzed. Body mass index (BMI) values were calculated and compared with data reported for the general population of the same nationality of seafarers examined. RESULTS: BMI values revealed a tendency to overweight, whereas blood glucose and systolic blood pressure values were in general in the normal range. Approximtely 40% of subjects investigated were overweight, and more than the 10% of them were obese. Underweight was noticeable only in 1.22% of crew members and 0.34% of officers. The 0.52% of subjects investigated was diabetic, and 2.68% were hypertensive. Seafarers, regardless their nationality and rank, showed a greater tendency to overweight and obesity compared with general population of the same ethnicity. CONCLUSIONS: Due to the occurrence of overweight and obesity among seafarers, campaigns for promoting awareness of the phenomenon and on the danger of these conditions for health should be promoted. Specific initiatives to avoid the assumption of junk food and the organization of adequate spaces, times and programs for physical exercise sessions on board should be offered for keeping seafarers healthier.
