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.
