経営規模および職務内容からみた船員の傷病(日本航海学会第22回講演会)

抄録

It was noticed the smaller the scale of business of shipping companies, the high the frequency of disembarkation of seamen due to diseases and injuries. This fact suggests the unfavourable working conditions in small enterprise. Regarding the relationship between morbidity and working conditions, the following points attracted the author's attention: 1. The incidence of tuberculosis was evidently high in those engaged in light work or taking the night shift, especially the midnight. 2. In the engine and catering department, vitamin B1 deficiency, diseases of vein and urogenital system were more frequent. 3. The incidence of neuropsychosis was higher among radio officers and engine officers. 4. The accident rate of sailors was the highest among all due to cargo work. 5. The morbidity rate in the engine department decreased remarkably in the past several years.
