Background: The aim of this study was to screen for musculoskeletal disorders (MSD) complaints, to analyse the activity and to identify their risk factors.
Materials and methods: This cross-sectional epidemiological study involved 903 men aged > 20 years and with a seniority > 2 years. It included a questionnaire and an ergonomic analysis of the activity. The questionnaire included: socio-demographic and occupational characteristics, health status and life habits, stress and items from the Nordic questionnaire. The observation of work situations required video recordings and the use of three methods: Occupational Safety and Health Administration (OSHA), Rapid Upper Limb Assessment (RULA) and the Gesture Tracking and Assessment Tool (Outil de Repérage et d'Évaluation des Gestes: OREGE).
Results: The prevalence of MSDs was 61.9%. It was significantly higher among deckhands than among other professionals (65.6% vs 27.4%; p < 0.001) and in seasonal workers than in permanent workers (67.8% vs 43.1%; p < 0.001). A positive correlation was noted between MSDs and daily work duration. Stress was an aggravating factor, whereas leisure activities were protective. The prevalence of MSDs was 40.5% (lower back), 40.4% (wrist/hand joints), 34.6% (neck) and 31.7% (shoulders). The ergonomic analysis of the workstation was performed on a deckhand who unloaded the fish crates out of the hold of a trawler. OSHA score = 12 (normal < 5); significant risk of upper limb MSD. RULA total score = 7 (acceptable between 1 and 2); immediate modification. OREGE scores evaluating effort, repetitiveness and joint positions indicate that the actions were not recommended or to be avoided.
Conclusions: The analysis made it possible to evaluate the difficulty of the job and to note a high risk of MSDs requiring ergonomic and organizational improvements.

Background: Indonesia, with its expansive territorial waters, hosts numerous fishing communities residing on various islands. Many of these communities rely on diving activities, predominantly free diving without standardized safety equipment. This practice poses risks, including the potential for hypoxia-induced oxidative stress, which plays a role in disease pathogenesis. This study aimed to investigate the levels of malondialdehyde (MDA) in freediving fishermen and explore potential influencing factors.
Materials and methods: The research involved 30 freediving fishermen, aged 20-60, who engaged in diving at least twice weekly over the last 3 months. Blood plasma MDA levels were assessed using the Will method.
Results: Results revealed a median age of 40.5 years (range: 20-59), a body mass index of 23.1 ± 2.8, and a mean blood pressure of 132/85 mmHg. A significant portion of the subjects exhibited smoking habits (90%) and alcohol consumption (76.7%). The median MDA level among subjects was measured at 0.42 nmol/mL (range: 0.34-0.70). However, no discernible relationship was found between smoking habits, alcohol consumption, and MDA level categories, as determined by the Fisher exact test (p > 0.05).
Conclusions: While these findings shed light on the MDA levels in freediving fishermen, further research is warranted to explore additional factors that may influence these levels. This comprehensive understanding is crucial for addressing the health risks associated with free diving practices in this unique population.

Background: The Philippines is the global maritime industry's single biggest source of seafarers. This article examines how the Philippines protects the welfare of its seafarers working on board ocean-going vessels.
Materials and methods: We employed a multi-method approach to better understand the POEA-SEC as a regulatory instrument. First, we analysed Philippine legislation and regulations that are shaping the employment, welfare, and working conditions of Filipino seafarers. Second, we examined the Philippine Overseas Employment Administration Standard Employment Contract (POEA-SEC) which requires that minimum standards of employment for seafarers are met. We use legal analysis to examine three specific provisions that pertain to their well-being: duration of employment, monetary considerations, and working conditions in terms of hours of work and rest periods. Third, we analysed interview and focus group data on the experiences of Filipino seafarers on board ships in respect of the POEA-SEC's efficacy in protecting their well-being.
Results: Analysis of the policy environment for Filipino seafarers shows how the interests of powerful actors have taken precedence over those of Filipino seafarers. Seafarers' experiences suggest that they cannot be reached by the contract, whether symbolic or otherwise. The contract fails to address seafarer issues, such as security of tenure, excessive working hours resulting in fatigue, stress and anxiety.
Conclusions: The POEA-SEC falls short as a legal document to address occupational, health and safety issues, which contribute to the detriment of seafarers' health and well-being. This indicates that the Philippine government cannot fully protect its seafarers.

Purpose: Working on a ship is challenging for maritime workers. Ship movements and high physical workload on board are straining their musculoskeletal system, which can particularly lead to lower back pain (LBP). The purpose of this study is to review recent studies about the impact of moving environments on the lower back both of seafarers and fishermen and the frequency of related health complaints.
Methods: Using a systematic review in the PubMed database, 384 studies about musculoskeletal issues among maritime workers were identified in the period 2000 to 2021. Evaluation of studies was done according to the PRISMA statement.
Results: The review revealed 13 studies focusing on musculoskeletal issues of the lower back among maritime workers. Four studies used biomechanical modeling to examine the physical load on board. They all described high physical strain when performing heavy working tasks in moving environments and 2 described the need for compensational efforts due to ship movements. Ten studies examined the musculoskeletal health of seafarers or fishermen and pointed out that particularly fishermen suffer from increased rate of LBP. A comparison of the data of four studies, which comprise prevalence of LBP, depict higher prevalences on fishermen (between 60.95; 95% CI 51.62-70.28 and 82.13; 95% CI 77.23-87.03) than data from land-based population (48.63; 95% CI 46.62-50.64), while the study concerning seafarers showed lower prevalence (28.42; 95% CI 24.74-32.10).
Conclusions: The high prevalence of LBP among fishermen suggests that heavy physical work (e.g., operating of fishing nets, filleting process) during ship motions is a strong risk factor. Further studies should evaluate effects of ship movements on the lower back among maritime workers, considering the different activities on board of vessels. As in most physically challenging jobs with repetitive activities, consequent prevention might be a key to lower the morbidity.
目的:在船上工作对海事工人来说是一项挑战。船上的移动和高强度的体力劳动会给他们的肌肉骨骼系统造成压力,尤其会导致下背部疼痛(LBP)。本研究的目的是回顾近期有关移动环境对海员和渔民下背部的影响以及相关健康投诉频率的研究:方法:通过在 PubMed 数据库中进行系统回顾,确定了 2000 年至 2021 年期间有关海事工人肌肉骨骼问题的 384 项研究。根据 PRISMA 声明对研究进行评估:综述显示,有 13 项研究关注了海事工人的下背部肌肉骨骼问题。其中四项研究使用生物力学模型来研究船上的物理负荷。这些研究都描述了在移动环境中执行繁重工作任务时的高体力负荷,其中 2 项研究还描述了由于船舶移动而需要进行补偿的情况。十项研究对海员或渔民的肌肉骨骼健康进行了调查,并指出渔民患腰背痛的比例尤其高。对四项研究的数据进行比较后发现,渔民的枸杞多糖患病率(60.95;95% CI 51.62-70.28 和 82.13;95% CI 77.23-87.03)高于陆地人口的数据(48.63;95% CI 46.62-50.64),而有关海员的研究显示患病率较低(28.42;95% CI 24.74-32.10):渔民枸杞多糖症的高发病率表明,在船舶移动过程中从事繁重的体力劳动(如操作渔网、鱼片加工)是一个重要的风险因素。考虑到船上的不同活动,进一步的研究应评估船舶移动对海事工人腰背部的影响。与大多数重复性活动的体力挑战性工作一样,预防可能是降低发病率的关键。

Background: Commercial fishermen represent a particularly vulnerable group within the Blue Economy (BE), enduring hazardous working conditions, strenuous labor, prolonged exposure to extreme weather, and irregular sleep and nutritional patterns. The health of these invisible workers holds significant implications for the social, economic, and environmental dimensions of fisheries, as it directly influences productivity. Despite their importance, no public data are available on fishermen's cardiometabolic health and health behaviors in Rhode Island. However, sound evidence suggests elevated cardiometabolic risks, altered sleep patterns, and chronic stress in similar fishermen populations globally. This paper establishes a comprehensive research framework to examine commercial fishermen's cardiometabolic health, protective and risk factors, quality of life (QoL), lifestyle behaviors, and productivity. The overarching goal is to identify potential targets for intervention to improve commercial fishermen's health behaviors, QoL, and cardiovascular health.
Materials and methods: Following the STROBE guidelines, this framework includes methodological, societal, environmental, and economic aspects to guide the development of an exploratory study protocol. A two-phase mixed-methods study will be conducted. Phase 1 (qualitative) will hold two focus groups (n = 6-10 participants per group) and will inform Phase 2 (quantitative), where biomarkers, health factors and behaviors, QoL, and productivity of commercial fishermen (n = 59) will be gathered.
Results: Recruitment began in January 2024, and data collection will end in August 2024. The results of this study are expected to be published in 2025.
Conclusions: A framework was developed considering the impact and implications of commercial fishermen's health-related behaviors on BE-based states, sustainable communities, and marine ecosystems. This protocol established a guideline-based, two-phase mixed-methods study to explore the cardiometabolic health, QoL, and productivity of commercial fishermen. Since better cardiovascular health is associated with lower risks of cardiovascular disease death and all-cause mortality, the findings will provide a situational screening and inform the development of tailored theory-based preventive behavioral interventions.

Background: In confined waters, ships run a high risk of groundings, contact, sinkings and near misses. In such waters the maritime traffic is dense, the waterway is narrow, the depth is limited, and tides and currents are constantly changing.
Materials and methods: From 2009-2019, 75 accidents were investigated in the estuary of the Seine. Weather conditions and perceived fatigue were studied. From May to June 2020, 114 seafarers, 34 pilots and 80 captains, responded to a questionnaire focusing on the use of Pilot Portable Units (PPU) and Electronic Chart Display Information Systems (ECDIS).
Results: The 75 accidents corresponded to an average of 6.8 ± 3.2 accidents per year. Groundings were the most frequent accidents (35%, n = 26) followed by contact accidents with the quayside (25%, n = 19), between ships or tugs while manoeuvring (8%, n = 6) or while sailing (1%, n = 1). There was no loss of vessels nor fatalities of crew members. In poor weather conditions, there were 76% more accidents than in normal conditions (4.4 ± 2.5 accidents/10,000 movements versus 2.5 ± 1.9 accidents/10,000 movements, p < 0.03). Almost all the accidents (96%) were related to human errors of judgment (81%), or negligence (53%), or both (39). Perceived fatigue was probably in cause in 6 accidents. Only 3 accidents were related to mechanical causes. Through the questionnaires, 69% of the pilots complained of difficulties in mastering the devices and software. They felt distracted by alarms which affected their attention while navigating. They requested training on a simulator. Concerning ship captains, 83% felt comfortable with ECDIS devices yet only 20% were able to configure the ECDIS correctly.
Conclusions: In the Seine estuary, 75 accidents occurred within the 11 year-study. Risk factors were poor weather conditions and human error. PPU and ECDIS were considered as useful tools in the prevention of accidents. However, pilots and captains requested more thorough training in their use.

Background: Sickle cell disease (SCD) is one of the most severe haemoglobinopathies, a group of blood disorders, typically inherited. The condition affects over 7.7 million people globally and results in more than 370,000 deaths per year. The highest morbidity and mortality rates are seen in Africa and most children with SCD are born in Tanzania. The available literature on SCD morbidity in Tanzania focus primarily on the residents of the mainland, while there is little data available on SCD morbidity among residents of the Tanzanian islands in the Indian Ocean. The aim of the present study was to confirm the presence of sickle cell disease among residents of the Zanzibar Archipelago.
Material and methods: The study group consisted of 27 people, residents of Pemba Island in the Zanzibar Archipelago, aged between 2 months and 26 years old, whose at least one parent has been diagnosed with sickle cell anaemia. Blood samples collected from the study participants were tested using HemoTypeSCTM, a rapid, point-of-care diagnostic test. The tests were performed at the Amal Hospital (Chake Chake town, Pemba Island) in June 2023.
Results: Sickle cell disease was diagnosed in 11 study subjects (40.7%); their haemoglobin concentration ranged between 6.6 and 8.5 g/dL. The presence of the sickle cell trait (HbAS phenotype) was confirmed in 14 patients (51.9%). Only two of the tested patients had normal haemoglobin phenotype.
Conclusions: The results of the present study support the necessity to introduce large-scale population- -based screening for SCD in the Zanzibar Archipelago, especially in infants whose family members have sickle cell anaemia. The introduction of such a programme will help monitor the number of new SCD cases in the region and may potentially reduce infant mortality due to SCD as well as minimize complications from SCD in older children through the adoption of effective disease prevention measures.

The aim of the present study was to confirm the presence of sickle cell disease among residents of the Zanzibar Archipelago.</p><p><strong>Material and methods: </strong>The study group consisted of 27 people, residents of Pemba Island in the Zanzibar Archipelago, aged between 2 months and 26 years old, whose at least one parent has been diagnosed with sickle cell anaemia. Blood samples collected from the study participants were tested using HemoTypeSCTM, a rapid, point-of-care diagnostic test. The tests were performed at the Amal Hospital (Chake Chake town, Pemba Island) in June 2023.</p><p><strong>Results: </strong>Sickle cell disease was diagnosed in 11 study subjects (40.7%); their haemoglobin concentration ranged between 6.6 and 8.5 g/dL. The presence of the sickle cell trait (HbAS phenotype) was confirmed in 14 patients (51.9%). Only two of the tested patients had normal haemoglobin phenotype.</p><p><strong>Conclusions: </strong>The results of the present study support the necessity to introduce large-scale population- -based screening for SCD in the Zanzibar Archipelago, especially in infants whose family members have sickle cell anaemia. The introduction of such a programme will help monitor the number of new SCD cases in the region and may potentially reduce infant mortality due to SCD as well as minimize complications from SCD in older children through the adoption of effective disease prevention measures.</p>","PeriodicalId":45964,"journal":{"name":"International Maritime Health","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140866802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Background: The World Health Organization (WHO) reported an estimated 249 million malaria cases globally in 2023, of which 94% were reported from Africa. Tanzania, a Sub-Saharan African country, has an exceptionally high malaria prevalence (3.6 million in 2023). The aim of the present study was to assess malaria prevalence rates in the Arusha Region, northern Tanzania. This region is famous for its national parks and wildlife reserves, and it is visited by thousands of tourists from all over the world each year. The assessment of malaria prevalence in the region is important in the context of the necessity to administer antimalarial chemoprophylaxis to international travellers.
Material and methods: The study group consisted of 101 people, residents of the Karatu District in the Arusha Region, aged between 1 and 73 years, who volunteered to participate in the screening. Phase I of the study was conducted in July 2022 in the Karatu Lutheran Hospital in Karatu Town (located close to the Ngorongoro Conservation Area and the Serengeti National Park). During this phase a venous blood sample was collected from each patient. The samples were tested for malaria using a rapid diagnostic test (mRDT); the same samples were also used to measure haemoglobin concentration and next they were applied onto the Whatman FTA micro cards for further molecular diagnostics in Poland (phase II).
Results: mRDT detected two (2.0%) infections caused by Plasmodium (the etiological factor of malaria), the molecular tests (RT-PCR) confirmed the two positive results by mRDT but also detected infections in six other samples (7.9% in total). The study found that six patients were infected with the Plasmodium falciparum species, while two other subjects had co-infections (P. falciparum + P. ovale, P. falciparum + P. vivax + P. malariae).
Conclusions: The study findings confirm the prevalence of malaria in areas located close to national parks in northern Tanzania and support the use of antimalarial chemoprophylaxis in international travellers visiting the area. The present study found co-infections caused by four different species of Plasmodium species which supports the prevalence of different parasitic species in Sub-Saharan Africa and is in line with CDC reports but contrary to WHO reports which estimate that 100% of malaria cases in Sub-Saharan Africa are caused by P. falciparum.

Background: In a working environment that is predominantly male, very tough physically, with a difficult working environment, occupational exposures and working, verbal and physical aggression can be more frequent than in other sectors. Fishing, merchant shipping and yachting are all sectors where fitness to sail is reassessed every year by doctors in the Seafarers' Health Service. Seafarers are increasingly reporting insulting, violent or sexist behaviour. The main types of abuse seen on board can be verbal and/or physical aggression, humiliation, whether in private or in front of others. Sexual harassment of women is a very worrying subject.
Materials and methods: It was a retrospective observational study which is part of the professional monitoring of seafarers. The target population was adult seafarers coming for a fitness to sail visit. The group was recruited from seafarers aged over 18 who were being monitored by one of the seafarers' health services (or local centres). The inclusion period was 4 months between January and April 2023. All the information was collected using a self-questionnaire developed from the questionnaires of the Surveillance Médicale des Expositions des Salariés au Risques Professionnels (SUMER) for health status, job satisfaction and the European mini-module, verbal and physical aggression and psychological violence at work (based on the Leymann questionnaire), sexual violence and aggression based on the sexual harassment questionnaire and the PCLS-5 scale validated and translated into French to assess post-traumatic stress. The population studied was therefore 788 sailors.
Results: The study population was predominantly male (82.3%). The average age was 41.4 years (standard deviation = 11.7). 46.7% of seafarers estimate being in very good health. During the past 12 months, overall, 24.5% of seafarers disclaimed having been victim in work-related context of a verbal aggression, with a significant difference according to the gender (21.1% for men and 41.0% for women). During the last 12 months, overall, 3.2% of seafarers have been victim in work-related context of a physical aggression (2.6% for men and 5.8% for women, NS), whereas 10.9% of seafarers reported hostile behaviour at present. Twenty per cent of seafarers reported sexual harassment in the last 12 months. During the entire working life of seafarers, 65.5% of women and 38.2% of men reported sexual harassment, and 38.8% of seafarers stated that they had experienced at least one traumatic event in the last 12 months.
Discussion: A quarter of seafarers say they have been the victim of verbal or physical aggression at work in the last twelve months. These figures are high, and higher than those of the global survey on violence and harassment at work carried out by the International Labour Organization. One of the most alarming results of our study is the overexposure of wo
