Background Employees on board must be highly qualified in order to be able to independently meet the different work requirements during the three voyage stages of a ship (port stay, river and sea passage). In this study, the activity profiles of the various occupational groups on container ships are presented according to the voyage stages.

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.
The aim of the present study is to assess the extent to which seafarers had been affected by severe mental stress situations and what possible psychological effects they may have. During the voyages of 22 German ships, a psychologically trained investigator interviewed 323 seafarers about severe mental stress or potentially traumatic events on board (participation rate 88.5%). Furthermore, a psychologist conducted semi-standardized interviews in 12 shipping companies and in 8 stations of the Ger...

ABSTRACTSeafarers working in maritime settings are affected by a great number of psychosocial stressors. The testing of cortisol in saliva is a well-established method for judging the individual strain. Therefore, this study aims to assess the crews’ strain on container ships on the basis of this parameter, taking occupational groups and the three voyage episodes of the vessel into account (stay at port, river passage and sea passage). One scientist accompanied 22 sea voyages and examined 304 cr...
Objectives To estimate the prevalence of sleepiness on duty among day workers and watchkeepers on board. Design Cross-sectional survey in a maritime field study. Setting 10 shipping companies with container vessels under German management. Participants The whole crew (75 day workers and 123 watchkeepers) during 18 voyages on 18 different container ships. Outcome measures Sleepiness on duty and efficiency of sleep using pupillometry (in a cross-shift design) and the SenseWear armband activity mon...

Background A sea voyage is characterized by a variety of work requirements for the ship's crew, basically reflected in three voyage episodes: port stay, river passage and sea passage. The primary aim of this study was to compare stress and strain amongst a sample of merchant seafarers across these three voyage episodes. Methods In a cross-sectional maritime field study, 323 sailors on 22 container ships were biometrically surveyed and completed a questionnaire. In addition, a survey of energy ex...

Overweight and obesity is quite prevalent among seafarers. The present study examined differences in BMI and their association with weight, shape and nutrition related attitudes and perceptions among seafarer from Kiribati, a Pacific Island Group, and European origin. The Seafarer Nutrition Study compared 48 Kiribati and 33 European male seafarers from 4 commercial merchant ships. BMI was calculated from measured weight and height. Attitudes to weight, shape and nutrition and disinhibition of co...

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. 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 Ki...

BACKGROUND: Seafarers face numerous hazards during their work at sea. AIMS: To demonstrate the frequency and causes of mortality in German seafarers. METHODS: The deaths of all German seafarers from 1998 to 2008 were counted and evaluated using the German central civil register in Berlin. RESULTS: The study cohort comprised a total of 159588 seafarer-years. During the 11 year period, 68 male seafarers died on board. The average age was 48.5 years (SD 12.7 years) and comprised 35 deck officers, 1...
