The health and lifestyle of Scottish fishermen: a need for health promotion

Age Group-Wise Burden of Non-Communicable Diseases Among Shrimp Cultivators in India: A Retrospective Analysis of Disability-Adjusted Life Years Method

OBJECTIVE

Despite generating huge employment opportunities and profitable business, fishing is considered a dangerous occupation due to challenging weather conditions and exposure to unhealthy occupational factors and lifestyles, which contribute to various health issues. However, few studies have examined the health status of shrimp cultivators. Consequently, this study aims to estimate the age group-wise burden of non-communicable diseases (NCDs) among shrimp cultivators.

METHODS

Simple random sampling was employed for collecting data. The sample size was 357 shrimp cultivators. Disability-adjusted life years (DALY) and relative risk (RR) methods were used to measure the burden of NCDs among shrimp cultivators. This study reported the burden of NCDs per 100,000 shrimp cultivators.

RESULTS

The top five prevalence of NCDs per 100,000 shrimp cultivators were mental disorders (85,434), musculoskeletal diseases (26,325), digestive diseases (9,803), diabetes (5,882), and cardiovascular diseases (4,481). DALY per 100,000 shrimp cultivators was 33,407.59, while at the national level, it was 24,775.99 per 100,000 people across all age groups. The RR of NCDs among shrimp cultivators in terms of DALY was 1.35, indicating a 0.35 times higher burden of NCDs among shrimp cultivators than at the national level. The largest RR of NCDs was found among shrimp cultivators aged 15-49 years (1.85), followed by 50-69 years (1.09). The highest percentage changes in the burden of NCDs among shrimp cultivators, resulting from changes in the methods of estimating DALY, was observed in the age group of 70 years and above (-48.36%) followed by 15-49 years (-46.08%) and 50-69 years (-40.33%) when compared to the baseline method of estimating DALY without utilizing age weightage and discount rate.

CONCLUSIONS

Focus should be given to improving the lifestyle and occupational factors of shrimp cultivators to mitigate the burden of NCDs.

Health Hazard Among Shrimp Cultivators in India: A Quantitative Burden of Disease Study

Background

The lack of focus on the health status of shrimp cultivators by previous studies while the production of shrimp has been rising over the years after the introduction of the blue revolution in India. The present study estimated the burden of diseases among shrimp cultivators in India.

Methods

Primary data were collected by using simple random sampling. The sample size was 357. The classification of diseases were made by using the international classification of diseases, tenth revision (ICD-10), version 2019. Disability-adjusted life years (DALY) were used to measure the health status of shrimp cultivators. DALY is the summation of the burden of disease from mortality and morbidity. Sensitive and uncertainty analysis was used by changing the value of the parameter and method, respectively.

Results

The burden of disease among shrimp cultivators in 2020 ranges from 101.03 DALY based on equal age weightage, without discount rate, and potential life expectancy (DALY0,0,PLE) to 84.02 DALY based on unequal age weightage, discount rate, and standardized life expectancy (DALY1,0.03,SLE). The burden of disease per 100,000 shrimp cultivators was 28,477.74 DALY and 23,600.84 DALY when calculated by using DALY0,0,PLE and DALY1,0.03,SLE method, respectively. The higher burden of diseases from non-communicable diseases was followed by injury and communicable diseases for both methods. The disease burden from mortality was more than two-thirds of the total burden of disease and the rest from morbidity. The burden of disease among shrimp cultivators was sensitive to parameter changes because it changes between 92.10 DALY and 63.03 DALY with the change in the parameter. Uncertainty in the burden of disease among them was due to method variation, which ranges from 120.03 DALY to 74.06 DALY.

Conclusion

The higher burden of non-communicable diseases, and the lower burden of communicable, and injuries per 100,000 shrimp cultivators compared to the national level in India.

Assessment of nutrient adequacy in undergraduate students during the undertaking shipboard internship: using 12-day dietary recall through smartphone photography

BACKGROUND

This study aimed to investigated nutritional status and estimated the adequacy of dietary intake of university students during shipboard internships.

METHODS

In this cross- sectional study, data were collected from 25 students out of 42 participants who attended in the research information session in the department of maritime at a university located in Jeonbook, South Korea. The dietary intake data was obtained using the 12-day dietary recall through smartphone photography during the shipboard internships. The data on dietary intake were used to calculate acceptable macronutrient distribution ranges (AMDRs), frequency of inappropriate intake of the 2020 Dietary Reference Intakes for Koreans (KDRIs) as a reference, intake ratio to the nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ).

RESULTS

The average age of subjects was 21.68 years and average BMIs in men and women were 25.67 kg/m2 and 23.44kg/m2, respectively. The average energy of men and women was 2018.66 kcal and 1727.87 kcal, respectively. More than half of the subjects did not meet the inappropriate range of the AMDRs for carbohydrates and fat. The NAR of vitamin A, vitamin C, and calcium among all 10 nutrients tended to be lower in both men and women. The MAR were 0.71 and 0.769. On the other hand, in both men and women, vitamin C had the lowest INQ (0.5 and 0.39). For men, grains and potatoes were the major contributors to energy and carbohydrates, and calcium contributed in the order of meat, fish and eggs and vegetables and fruits. Although the highest contributors to energy and carbohydrates for women were grains and potatoes, the contributions from meat, fish, and eggs were similar, and the major contributors to calcium were vegetables and fruits.

CONCLUSIONS

To improve the inadequate nutritional status of university students engaged in shipboard internships with the aim of pursuing careers as seafarers, there is a need to provide additional nutritional education tailored to their specific circumstances. Additionally, professional health guidance should be provided to maintain optimal nutritional status.

Overview of oral health status and associated risk factors in maritime settings: An updated systematic review

OBJECTIVES

The aim of this study is to provide an updated overview of the oral health status and associated risk factors in maritime settings.

METHODS

We systematically searched PubMed, Ovid Embase, Web of Science, CINAHL and SCOPUS from January 2010 to April 2023. Two independent reviewers extracted the data. The quality of included studies was assessed using relevant assessment tools.

RESULTS

A total of 260 records were found in the initial search; 24 articles met the inclusion criteria. Most studies had descriptive design, and only two randomized controlled trials were found. The main oral health issues noted are oral cancer, dental caries, periodontal diseases, oral mucosal lesions, and dental emergency. Male seafarers have higher risk of oral cancers in the tongue, lips, and oral cavity while oral mucosal lesions are more prevalent among fishermen.

CONCLUSIONS

Dental caries and periodontal diseases are prevalent in both seafarers and fishermen. The consumption of tobacco, alcohol, fermentable carbohydrate, and poor oral hygiene are risk factors that affect the oral health status at sea. The occurrence of oral diseases in maritime setting requires more attention of researchers and authorities to develop strategies to tackle these issues.

Global overview of dietary outcomes and dietary intake assessment methods in maritime settings: a systematic review

BACKGROUND

Seafaring is a risky occupation with high prevalence of risk factors for non-communicable diseases. Food intake and eating habits are important cornerstones regarding health and health promotion. The aim of this study was to provide an overview of dietary intake and dietary intake assessment methods of seafarers and suggestions for applicable assessment tools.

METHODS

We systematically searched PubMed and NLM Gateway (for MEDLINE), Web of Science, and SCOPUS up to February 2020 using standard keywords including nutrition OR diet OR meal AND maritime settings. Two independent reviewers extracted the data. The quality of included studies was assessed using the Joanna Briggs Institute Critical Appraisal checklist.

RESULTS

From 4449 studies initially identified, 26 articles were included in the final review. Qualitative data (e.g. on unhealthy eating) had been gathered using in-depth individual or group interviews, participant observations, and phone-based chats. Composition of menu analysis, 24 h dietary recall, food diaries/ diet records, dietary habits questionnaire, food stores and food waste of the ship were used to assess the quantitative outcomes (e.g. dietary intakes). Access to meat, processed meat and egg, frozen and canned food items, sugary drinks, alcohol, greasy and salty food was high. In contrast, consumption of fruit, vegetables, dairy products, and cereals was lower than recommended.

CONCLUSIONS

Eating habits and dietary intakes in maritime settings are unhealthy. Subjective dietary assessment methods combining menu analysis with new technologies (e.g. mobile-based) might be an applicable method in this hard to reach setting which is the vessels.

Health Literacy Co-Design in a Low Resource Setting: Harnessing Local Wisdom to Inform Interventions across Fishing Villages in Egypt to Improve Health and Equity

Fishermen in low resource settings have limited access to health services and may have a range of health literacy-related difficulties that may lead to poor health outcomes. To provide solutions and interventions based on their needs, co-design is considered best practice in such settings. This study aimed to implement a co-design process as a step towards developing health literacy interventions to improve health and equity in the Borollos Lake region of northern Egypt, a low resource setting with a high prevalence of chronic diseases. This study was guided by the Ophelia (Optimising Health Literacy and Access) process, a widely used and flexible co-design process that seeks to create local and fit-for-purpose health literacy solutions through genuine engagement and participation of community members and relevant stakeholders. Following a health literacy survey using the Health Literacy Questionnaire (HLQ), cluster analysis was conducted to identify the diverse health literacy profiles among the fishing communities. Seven health literacy profiles were identified. Vignettes, representing these profiles, were presented and discussed in ideas generation/co-design workshops with fishermen and health workers to develop intervention ideas. Seventeen fishermen, 22 wives of fishermen, and 20 nurses participated in four workshops. Fifteen key strategies across five themes, including ‘Enhancing education among fishing communities’, ‘Provide good quality health services’, ‘Financial support for health’, ‘Social support for health’, and ‘Promote better health-related quality of life among fishermen’, were generated. The ideas did not only target the individuals but also required actions from the government, non-government organizations, and fishermen syndicates. By harnessing local wisdom, the Ophelia process has created meaningful engagement with the local communities, leading to a wide range of practical and feasible solutions that match the special needs and environment of a low resource setting.

A cross-sectional study to identify the determinants of non-communicable diseases among fishermen in Southern India

Background

India is currently facing a rising epidemic of Non-Communicable Diseases (NCDs). Identification of modifiable risk factors is of paramount importance to curb this menace. Fishermen are one of the most vulnerable occupational groups with unique characteristics that make them prone to acquire NCDs, as a significant share of their life is spent at sea. Hence, this study was planned to ascertain the burden of NCDs, determine various risk factors of NCDs, and measure the association between risk factors and NCDs among fishermen of Coastal Karnataka in South India.

Methods

A cross-sectional study was conducted among 681 fishermen aged 18 years and above as per the semi-structured interview schedule for two years (2017–2019). A convenience sampling strategy was adopted. The data was entered and analyzed using SPSS v.15.0. The results were described in terms of proportions and their 95% confidence intervals. Continuous data were summarized using the mean and standard deviation or median and interquartile range depending on the skewness of data. Chi-square test was used to study the association between NCDs and modifiable risk factors. Multiple logistic regression was used to identify risk factors of NCDs.

Results

The mean (SD) age of the population was 42.5 (SD 12.5) years. The mean years involved in fishing was 19.8 years (SD 10.9). More than half (59.5%) of the study participants had severe stress and most (80.3%) were ever substance users. Advancing age, not being able to contact family while at sea, poor dietary practice, ever substance use, increasing waist circumference were significant correlates of NCDs.

Conclusions

The commonly prevalent risk factors of NCDs among fishermen included poor dietary practice, higher stress levels, substance use, increasing waist circumference, and inability to contact with family while at sea. Hypertension and Diabetes were the two common NCDs in the study population. There is a need for immediate attention in managing NCDs’ risk factors by promoting a healthy lifestyle by primary health care providers through a sustainable community awareness program targeting fishermen at a convenient time and location, either at the sea-port or meeting places. Harmful effects of substance use, healthy dietary practices, and the importance of physical activity outside their job need emphasis. In addition, screening programs should be organized with the help of boat owners and fishing associations at-least once a year to pick up NCDs at an early stage.

Cancer incidence after childhood irradiation for tinea capitis in a Portuguese cohort

OBJECTIVES

Our aim was to compare cancer incidence in a cohort exposed in childhood (1950-63) to a therapeutic dose of radiation in the North of Portugal and followed-up until the end of 2012, with the incidence rates for the same age and sex in the general population.

METHODS

A population-based North Region cancer registry (RORENO) was used to assess which members of the cohort developed cancer. The association between radiation exposure and overall and specific cancer sites was evaluated using standardised incidence ratios (SIR).

RESULTS

Over the full follow-up period, 3357 individuals of the 5356 original tinea capitis (TC) cohort (63%) were retrieved in the RORENO, and 399 new cancer cases were identified, representing an increased risk of 49% when compared with the general population (SIR = 1.49; 95% CI: 1.35-1.64). The risk was slightly higher in males than in females (SIR = 1.65; 95% CI: 1.43-1.89 vs SIR = 1.35; CI = 1.17-1.55). The risk was slightly higher in the individuals exposed to a higher radiation dose (SIR = 1.78; 95% CI: 1.22-2.51 for ≥630 R vs SIR = 1.46; 95% CI: 1.31-1.62 for 325-475 R). In females, there was an excess cancer risk in all cancers with the higher radiation dose (SIR = 2.00; 95% CI: 1.21-3.13 for ≥630 R vs SIR = 1.30; 95% CI: 1.11-1.51 for 325-475 R) which was not observed in males, and for combined dose categories significantly raised SIRs for thyroid and head and neck cancer, suggesting a possible higher radiosensitivity of females. An increased risk was also observed for some cancers located far from the irradiated area.

CONCLUSIONS

The results suggest an association between radiation exposure and later increased cancer risk for cancers located near the radiation exposed area, mainly thyroid, and head and neck cancers. Further studies are necessary to disentangle possible non-radiation causes for distant cancers increased risk.

ADVANCES IN KNOWLEDGE

This paper shows a possible association between childhood X-ray epilation and increased risk of cancer which was not previously investigated in the Portuguese TC cohort.

Survey on smoking habits among seafarers

BACKGROUND

Populations living in stressful environments experience higher mortality from lung cancer and chronic diseases. Work-related stress was identified as important determinant of smoking together to health problems caused by a incorrect lifestyles. Aim of the work was to analyze tobacco smoking addiction in seafarers working on merchant ships. Only a few studies are available on this topic.

METHODS

The survey was conducted using an anonymous questionnaire. The total number of questionnaires filled-in was 1478, out of 2000 distributed (response rate 73.9 %).

RESULTS

About half of the sample (55.07%) has never smoked, the 28.96% is currently a smoker, while 15.97% of responders belong to the category of ex-smokers. Analysis of the number of cigarettes smoked every day based on the rank shows that captains and officers smoke more cigarettes than the crew members who smoke 10 cigarettes maximum per day. Analysis of the level of dependence among the smokers group by the Fagerström Test for Nicotine Dependence (FTND) revealed that a 89.0% of sample has a low/very low dependence level, and only the 10.98% of the sample show a high/very high dependence. A further analysis of the results of FTND in the different age groups has shown that the 41-50 and 51-60 age groups have high dependence levels.

CONCLUSIONS

Working on board is associated to a high risk for chronic, lifestyle-related diseases, due also to lifestyle behaviours. This study suggests to further investigate the presence of other risk factors such as diet, physical exercise, combined with tobacco smoking, obesity. (www.actabiomedica.it).

Lifestyle behaviour and prevalence of cardiovascular risk factors - a pilot study comparing Kiribati and European seafarers

Background

According to internal observations within a German shipping company, obvious risk-behaviour persists among the crew members coming from the Pacific Island State of Kiribati and representing a large part of the crew aboard merchant vessels of this company. These observations were related to excessive eating habits. This study aims to assess the cardiovascular risk among seafarers and to compare lifestyle factors between Kiribati and European crew members.

Methods

In the present maritime field study 81 sailors (48 Kiribati, 33 European, average age at 38.9 and 36.8 years respectively) were examined from April until August 2014 aboard four container ships crossing the Atlantic Ocean (participation rate of 90.9%).

Results

Based on the number of established risk factors, 35.4% of the Kiribati and 16.7% of the European crew members were regarded as a high risk group for cardiovascular diseases. The HDL-values of Kiribati were found to be considerably lower (34.9 mg/dl) than the references values given by the WHO and in comparison to the European crew members (44.8 mg/dl) (p = 0.002). 91.7% of Kiribati and 51.5% of European participants were found to be overweight according to WHO-criteria - with a mean Body Mass Index (BMI) of 30.3 kg/m² and 25.6 kg/m² (p <  0.001). Regarding lifestyle factors Kiribati often claimed to eat significantly larger amounts of food aboard while most European sailors stated to eat less or about the same during their shipboard stay (p = 0.017). Daily sleeping hours were slight on both sides; however with a mean of 5.2 h a day Kiribati crew members had significant fewer sleep (p = 0.038). The examined Kiribati sailors had a mean increase in weight of 6 kg over a 12 months period of observation.

Conclusions

In total the compiled data points towards a higher risk of cardiovascular diseases particularly due to alimentary habits within the Kiribati crew members. The distinct weight-gain measured among the Kiribati in spite of higher energy consumption levels at sea is alarming. Thus, the results of this study confirm the necessity of health-improving interventions aboard cargo vessels.

Food offerings on board and dietary intake of European and Kiribati seafarers - cross-sectional data from the seafarer nutrition study

Background

Overweight and cardiovascular risk factors are a common phenomenon in seafarers. According to internal observation particularly crew members from the Pacific Island State of Kiribati are exposed to a high risk. However, in mixed crews, cultural background plays an important role, influencing food choice, and the actual risk.

Methods

The Seafarer Nutrition Study (SeaNut study) compared dietary factors in 48 Kiribati and 33 European male seafarers recruited from four merchant ships with a high level of Kiribati manning within a German shipping company. Analysis encompassed the assessment of dietary quality on board, satisfaction with prepared dishes, and individual food intake obtained from 24-h recalls in comparison with nutritional recommendations.

Results

The overall supply of meat, fat and eggs was more than double, whereas the proportions of fruits, vegetables, dairy products and cereals were much lower than recommended. Based on the reported food choices, both groups, but notably Kiribati seafarers, did not reach reference values as to macronutrient, micronutrient and fiber intake. In addition, satisfaction with the meals served, food preferences and knowledge about a healthy diet varied markedly between Kiribati and Europeans.

Conclusions

The present analysis of the SeaNut study revealed the necessity of future health intervention programs, including the quality of the food supply as well as information about a healthy diet and adequate food selection. In mixed crews, culture-specific differences should be considered, in order to facilitate the long-term success of interventions.

Prevalence of Tobacco and Alcohol Consumption among Fishermen in Udupi Taluk' Karnataka, India: a Cross-Sectional Study

BACKGROUND

Stress associated with fishing is known to trigger consumption of alcohol and tobacco among fishermen. This study aimed to assess the prevalence of tobacco and alcohol consumption among fishermen in Udupi Taluk in the state of Karnataka, India, and to study associations with health status and job stress.

MATERIALS AND METHODS

The study was conducted among 825 fishermen in Udupi Taluk of Karnataka between January-June 2015, using a two stage cluster sampling procedure. Associations between variables of interest were assessed using multivariable analysis and logistic regression models.

RESULTS

The prevalences of consumption of tobacco, alcohol and either of these substances were 64.2%, 45.6% and 86.9% respectively. There was a positive association between alcohol and any form of tobacco consumption with income but none with respondent's job stress and health status.

CONCLUSIONS

Our study concluded that fishermen with poor health status are seen more among tobacco and alcohol users.

Musculoskeletal Disorders in Northeast Lobstermen

BACKGROUND

The objective of this study was to report on the prevalence of musculoskeletal pain in lobstermen in the northeast USA.

METHODS

Crews were randomly selected from those licensed to fish in Maine and Massachusetts and followed prospectively. The survey used a Nordic Musculoskeletal Questionnaire format to characterize musculoskeletal disorders.

RESULTS

A total of 395 individuals participated. One half of the respondents reported low back pain. Back pain was attributed to or exacerbated by lobstering. Low back pain was prevalent among both captains and sternmen, while sternmen reported more hand/wrist pain than captains. Multiple locations for pain were common in individual participants.

CONCLUSION

Equipment or technology to assist material handling should be a priority, as the body segments with high prevalence of pain (back, hand/wrists, shoulders, knees) are all affected by the repetitive and forceful handling of the lobster traps.

Attitudes toward medication-assisted treatment among fishermen in Kuantan, Malaysia, who inject drugs

Fishermen who inject drugs represent an understudied group at high risk for HIV in Malaysia. This study describes fishing, drug use, and attitudes toward medication-assisted treatment (MAT) for opioid use disorders. Thirty-four male ethnic Malay fishermen completed semistructured interviews analyzed by content analysis. Analysis revealed four themes surrounding opioids, which they called ubat ("medicine"): (a) the fishing lifestyle facilitating substance use, (b) previous unsuccessful attempts to quit, (c) categorizing substances as haram or halal, and (d) attitudes toward MAT. Fishermen's environment permits substance use, including injecting drugs on boats. Fishermen expressed more positive attitudes toward methadone and negative attitudes toward buprenorphine.

Alarmingly high level of alcohol use among fishermen: A community based survey from a coastal area of south India

INTRODUCTION

Though studies from western world have reported high prevalence of alcohol use among fishermen, there is lack of information from developing world. Hence this study was carried out among fishermen in a coastal area of southern India to 1) determine the prevalence of alcohol use among fishermen 2) describe the pattern of alcohol use 3) identify factors associated with alcohol use.

METHODS

A community based cross-sectional study was carried out among fishermen in a coastal village of Puducherry, India. House to hose survey was conducted, fishermen aged above 18 years and involved in catching fish at least once in last three months, were included. Data on age, marital status, education, monthly income, duration in fishing occupation, owning a boat or wager, frequency of fishing per month/week, number of hours spent in sea, alcohol use in past one year, age at initiation, type of alcohol drink and presence of alcohol users in family.

RESULTS

In total, 304 participants were interviewed. Mean (SD) age of the participants was 41 (11) and 82% were involved in fishing for more than 10 years. Of 304 participants, 241 (79%) reported alcohol use in past one year. Of 241 participants who used alcohol, 89% reported alcohol consumption during fishing activity. In multivariate analysis, alcohol use in other family members was independently associated with alcohol use (aRR 21.4; 95% CI 6.8-67.4).

CONCLUSION

Very high prevalence of alcohol use is seen among fishermen. Of those who consume alcohol, nine out of ten use during fishing activities.

Lesões oculares em trabalhadores da pesca comercial: uma revisão de literatura

Resumo Introdução: a pesca é uma atividade perigosa, associada à elevada morbimortalidade. Entretanto, são escassos os estudos sobre lesões oculares em trabalhadores desta atividade. Objetivo: identificar lesões oculares relacionadas à exposição ocupacional na pesca comercial e possíveis fatores de risco e de proteção relacionados. Métodos: revisão de literatura nas bases bibliográficas MedLine, LILACS-BIREME, SCOPUS, Web of Science e Cochrane, utilizando os termos de busca "pesca" e "lesão ocular". Foram incluídos: artigos completos disponíveis escritos em inglês, português ou espanhol, publicados de abril de 1993 a abril de 2013; e estudos em seres humanos. Resultados: foram incluídos 18 artigos, provenientes de 12 países. O desenho de estudo mais prevalente foi o de corte transversal. Discussão: as lesões mais frequentes se relacionavam com a exposição solar excessiva, como a catarata e a degeneração macular senil, e com traumas oculares, principalmente as lesões perfurantes pelo gancho de pesca ou por fragmentos de animais marinhos. Esses agravos foram relacionados com fatores de risco como o manuseio de peixes e frutos do mar e as jornadas prolongadas de trabalho. De acordo com os estudos, a maioria das doenças oftalmológicas relacionadas ao trabalho da pesca é prevenível, o que indica a necessidade de políticas de promoção de saúde direcionadas para a população envolvida com esse ramo.

Surveillance of hospital contacts among Danish seafarers and fishermen with focus on skin and infectious diseases-a population-based cohort study

Objectives: A systematic overview of time trends in hospital contacts among Danish seafarers and fishermen by job title and analyses on skin and infectious diseases. Methods: Occupational cohorts with hospital contacts 1994–1998 and 1999–2003. Standardized hospital contact ratios (SHCR) were estimated using national rates and ranked by SHCR size. Results: For non-officers in 1994–1998, infectious diseases had the highest SHCR, followed by neoplastic and endocrinal diseases; in 1999–2003 skin diseases were followed by endocrinal and gastrointestinal diseases. For fishermen in 1994–1998, nervous system, gastrointestinal, and skin diseases had the highest SHCRs; in 1999–2003 it was nervous system, skin, and lymphohematopoietic diseases. As for skin diseases, male fishermen and non-officer seamen generally had increased SHCRs, but engine room personnel specifically had a low SHCR for eczema (eight cases). Fishermen had high SHCRs for tuberculosis in both time periods (six and nine cases, respectively). Non-officer seamen on cargo ships had increased SHCRs for HIV in both time periods and for hepatitis in 1994–1999. Extending the follow-up until 2000 or 2005 showed similar results. Conclusions: Surveillance of seamen’s health gives useful information. The elevated SHCR for HIV infection among non-officers has not declined despite preventive information campaigns. Tuberculosis among fishermen may be due to infection on shore. Skin diseases had very high SHCRs, not due to cutaneous oil exposure.

An analysis of the respiratory health status among seafarers in the Russian trawler and merchant fleets

OBJECTIVES

Trawler fishermen and merchant seafarers have tough working conditions. While workers in both occupations are exposed to a challenging environment, trawler fishermen are also engaged in onboard fish processing, which is considered to be additional exposure. The aim of the present study was to characterize respiratory health status in both groups of seamen.

METHODS

In total 127 trawler fishermen and 118 merchant seafarers were enrolled during their regular medical health examinations. The study protocol comprised a standardized questionnaire, lung function test and measurements of fractional nitric oxide concentrations (FE(NO) ) in exhaled air.

RESULTS

Doctor-diagnosed asthma was reported only by trawler fishermen (3.9%, P < 0.05, Pearson Chi-square test). Adjusted odds ratios (OR) of respiratory symptoms were more often elevated in trawler fishermen compared to merchant seafarers. Trawler fishermen had reduced spirometric parameters: FEV(1) % of predicted values (adjusted β: -5.28, 95%CI: -9.28 to -1.27), FVC % of predicted values (adjusted β: -5.21, 95%CI: -9.25 to -1.17). Increased OR of the work-related cough with phlegm (OR: 6.6, 95% CI: 1.8-21.9), running nose (OR: 3.0, 95%CI: 1.2-7.7), and frequent sneezing (OR: 3.4, 95%CI: 1.0-12.7) were found among those trawler workers whose work tasks included filleting of fish. FE(NO) levels were not significantly different between trawler and merchant seamen.

CONCLUSIONS

The present study indicated that trawler fishermen exhibited impaired lung function and were more likely to have asthma. The environment of the onboard factories where fishermen fillet fish is suggested as a risk factor for work-related respiratory symptoms.

Occupational health of Turkish Aegean small-scale fishermen

BACKGROUND

Fishing has always been a dangerous occupation, and numerous factors have a direct or indirect impact on the health of fisherman.

AIMS

To examine the health, safety and working conditions of small-scale fishing fleets in the Turkish Aegean Sea coasts.

METHODS

Data were obtained from a questionnaire distributed to a random sample of small-scale fishermen along the Aegean Sea coast. Data collection took place between September 2009 and January 2010.

RESULTS

Out of 5714 Aegean Sea small-scale fishermen, 1166 from 76 fishing ports participated. Twenty-nine per cent of fishermen did not have any social security cover. The most prevalent health problems (using International Classification of Diseases and Related Health Problems 10th Revision [ICD-10]) found were musculoskeletal problems (e.g. discopathies, muscular strain, rheumatism) and eye, ear-nose, digestive and urinary system problems. Alcohol consumption was high (68%) in fishermen and 72% reported that they smoked more during fishing trips. Health problems appeared to be associated with a number of factors including migrant status, income satisfaction, rank, type of fishing and cumulative work per year.

CONCLUSIONS

In Turkey, small-scale fishermen experience a significant number of health problems and have unhealthy lifestyles. Interventions designed to improve working conditions of small-scale fishermen could help to reduce the number of occupational injuries, which in turn may impact positively on their health. Prevention policies to reduce alcohol and tobacco consumption should also be developed.

Psychoactive substances consumption in French fishermen and merchant seamen

OBJECTIVES

The aim of this study is to assess tobacco consumption, nicotine dependence as diagnosed by Fagerström test, alcohol consumption, alcohol dependence as diagnosed by CAGE questionnaire and drug consumption in French seamen. Results are presented according to job category: fishermen and merchant seamen.

METHODS

French seamen were recruited from a stratified survey of 19 ports in France. Subjects completed a questionnaire during their annual medical check-up. The questionnaire covered demographic and professional items, tobacco, alcohol and drug consumption behaviour. Nicotine and alcohol dependence were, respectively, assessed by the Fagerström Test for Nicotine Dependence (FTND) and a French version of the CAGE questionnaire. A urine test was used to detect cannabis derivatives.

RESULTS

Prevalence rates for current smoking and daily alcohol consumption were higher in fishermen than merchant seamen. The prevalence of nicotine dependence on FTND was likewise higher in fisherman smokers, who also showed more intense smoking behaviour. The category of seamen did not correlate with alcohol addiction, but differences in alcohol-related behaviour emerged between fishermen and merchant seamen. Prevalence of cannabis and other drug use was higher in merchant seamen, although the two categories of seaman did not differ with respect to recent use of cannabis. Demographic factors cannot fully explain these differences, as multivariate analysis showed significantly greater risks in marine fisheries.

CONCLUSIONS

Alcohol and tobacco consumption are a major public health problem for seafarers. Fishermen seem to be more liable to high consumption. Working conditions may explain these differences.

Characteristics of radio medical advice to fishing vessels in Scottish coastal waters

Summary

We examined the emergencies arising on fishing vessels in Scottish Coastal Waters which required ship-to-shore radio medical advice. All calls to the service were identified for the 12-month period from August 2005. A total of 186 calls were received; 38% of calls were from fishing vessels. During the study period 53% of the calls were trauma-related, while 47% were medical emergencies. Our data suggest that there are many fishermen working offshore with chronic medical conditions. Overall, 85% of calls from fishing vessels resulted in evacuation as the outcome. Improved occupational health screening, compliance with health and safety legislation, and an evidence-based approach to remote medical care may improve seafarer self-care and reduce emergency evacuations.

Hospital contacts for chronic diseases among danish seafarers and fishermen: a population-based cohort study

OBJECTIVES

Seafarers' and fishermen's working conditions may impact on their lifestyle and health. Standardized hospital contact ratios (SHCRs) were compared in two time periods and the relative risks of hospital contact as a function of employment time were estimated.

METHODS

Cohorts of all Danish seafarers (officers and non-officers) registered by the Danish Maritime Authority (DMA) 1989-98 and fishermen retrieved from a pension registry 1989-98 were linked to the nationwide Occupational Hospitalization Registry (OHR) and followed up for incident diseases in two five-year time periods, from 1 January 1994 and 1 January 1999, respectively, using rates specific for age and calendar time for the entire Danish workforce as a reference.

RESULTS

The SHCRs for lung and cardiovascular diseases were high for non-officers. Among male officers, the SHCR for diabetes was high in the 1999 cohort and the SHCR for chronic heart diseases was statistically significantly higher in the 1999 than in the 1994 cohort. For both time periods high SHCR values were found for bronchitis, emphysema, cancer of the lung, alcohol-related liver diseases, and diabetes among male non-officers, and lung cancer among male officers. Among female non-officers, a high SHCR for skin melanomas was seen. Among fishermen high SHCRs for bronchitis, emphysema, lung cancer, and Raynaud's syndrome were found in both cohorts. No duration-response pattern was observed in any of the analyses, which may reflect health- and lifestyle-related selection into the trades or a healthy worker effect.

CONCLUSIONS

Danish seafarers, especially short-term employees, had an elevated risk of hospitalization for lifestyle-related diseases.
