Patterns of fatigue among seafarers during a tour of duty.

BACKGROUND: Work-related fatigue is associated with sickness absence and mental and physical health problems, and may increase the risk of accidents and injuries at work. Relatively little is known about fatigue among seafarers, particularly during a tour of duty. The aim of this study was to describe the pattern of day to day fatigue among seafarers during a tour at sea. METHODS: Participants from the offshore support, short sea and coastal, and deep sea sectors of the UK shipping industry completed daily diaries. Information about sleep and fatigue was collected each day on waking and retiring. RESULTS: Fatigue on waking was a more sensitive measure of cumulative occupational fatigue than fatigue on retiring. Fatigue on waking increased between the start and end of tour. This increase took place in particular during the first week at sea, and was most apparent among those on shorter tours of duty. CONCLUSIONS: Day to day changes in fatigue are measurable, and may vary among particular sub-groups of seafarers. Used among larger groups, such a diary method could help identify times and activities associated with the greatest risk.

SSRIs and cognitive performance in a working sample.

BACKGROUND: Studies of the impact of antidepressant use on cognitive performance have frequently been carried out among the elderly or on healthy volunteers. Comparatively little research has considered their impact on a relatively young, working population, particularly within the context of everyday life. AIMS: To examine any association between SSRI use and cognitive performance, mood and human error at work. METHODS: SSRI users and controls completed a battery of laboratory based computer tasks measuring mood and cognitive function pre- and post-work at the start and end of a working week. They also completed daily diaries reporting their work performance. RESULTS: SSRI use was associated with memory impairment: specifically poorer episodic, though not working or semantic memory. Effects of SSRI use on recognition memory seemed to vary according to the underlying psychopathology, while effects on delayed recall were most pronounced among those whose symptoms had not (yet) resolved. There were no detrimental effects on psychomotor speed, attention, mood or perceived human error at work. CONCLUSIONS: The findings lend support to the SSRIs comparative safety, even among workers, particularly as the symptoms of the underlying psychopathology are successfully addressed. Possible memory impairments may, however, be found in those taking SSRIs.

Minor injuries, cognitive failures and accidents at work: incidence and associated features.

BACKGROUND: There is a dearth of information examining minor injuries and cognitive failures in the workplace. AIMS: This study aims to describe the incidence of, and characteristics associated with, minor injuries, cognitive failures and accidents in the workplace. METHODS: The study was a community based postal questionnaire survey of people selected at random from the Electoral Registers of Cardiff and Merthyr Tydfil; 7980 questionnaires were returned. RESULTS: Frequent/very frequent minor injuries were reported by 9.8% of the workers and frequent/very frequent cognitive failures (e.g. problems of memory, attention or action) by 10.5%. Work accidents requiring treatment were reported by 5.6% of the workers. Minor injuries, cognitive failures and accidents were associated with a number of demographic and health factors. In addition, minor injuries, cognitive failures and accidents were found to be related to each other. CONCLUSIONS: A large number of workers experience accidents and minor injuries at work. Minor injuries are not recorded by official sources but could have implications in productivity and worker health. Factors identified in this study, as associated with injuries or accidents, could be addressed by specific workplace policies or by raising individual awareness of the risks.

Recreational drug use: patterns from a South Wales self-report survey.

This study aimed to examine patterns of illicit recreational drug use, alcohol consumption, and smoking in a community-based population sample. A postal questionnaire survey was conducted of people who were selected at random from the Electoral registers of Cardiff and Merthyr Tydfil. Twelve percent of respondents reported illicit recreational drug use in the last year, and 7% in the last month. Among respondents aged under 25 years, 34% (39% of males and 31% of females) had used illicit drugs in the last year, and 19% (23% of males and 17% of females) in the last month. Twenty-one percent of respondents smoked (20% of males and 22% of females). Twenty-seven percent of respondents reported drinking more alcohol than currently recommended sensible limits (36% of males and 21% of females). Among respondents aged under 25 years, 53% of men and 38% of women drank over these limits. Illicit drug use was associated with heavy alcohol consumption and, in particular, with smoking. Smoking and heavy alcohol consumption combined was most strongly associated with illicit drug use. Rates of illicit recreational drug use were higher than have previously been reported for Wales. Illicit drug use and smoking varied with age, sex, work status and geographical location, whereas heavy alcohol consumption varied with age, sex and work status, but not geographical location. Both smoking and alcohol consumption were associated with illicit drug use, with smokers who were also heavy drinkers being those most likely to report illicit drug use.

Factors associated with recreational drug use.

This study aimed to examine demographic, lifestyle, mental health and personality factors associated with illicit recreational drug use, heavy alcohol consumption and smoking in a community-based population sample. A postal questionnaire survey was conducted of people who were selected at random from the Electoral registers of Cardiff and Merthyr Tydfil. Illicit drug use was associated with risk taking, neuroticism, being male, having a higher education qualification, not being married, being unemployed, being aged under 25 years, smoking, heavy alcohol consumption and living in Cardiff. Smoking was associated with anxiety, depression, being female, lower income and educational qualifications, looking after the family or home, being aged over 25 years, illicit drug use and heavy alcohol use. Heavy alcohol consumption was associated with not being depressed, experiencing sleeping problems, risk taking, being male, higher income, no higher educational qualification, not being married, being a student, being aged under 25 years, smoking and illicit drug use. Illicit drug use, smoking and heavy alcohol use were strongly associated with each other. Illicit drug use was associated with alcohol use and, to an even greater extent, with smoking. Illicit drug and alcohol use were associated with similar characteristics, but smoking was associated with a rather different demographic combination.

Preliminary investigation of the association between psychotropic medication use and accidents, minor injuries and cognitive failures.

RATIONALE: Psychotropic medication may impair psychomotor and cognitive function, and so increase accident susceptibility. However, few studies examine any association in the framework of other demographic, health and occupational factors. OBJECTIVES: To examine the relationship between sleeping tablets and antidepressants, and accidents, minor injuries and cognitive failures. METHODS: Postal questionnaire study of 3111 individuals who participated in an earlier phase of the Bristol Stress and Health Study. RESULTS: Sleeping tablet use was associated with accidents, minor injuries and cognitive failures both at work and outside work. Antidepressant use was associated with accidents and cognitive failures both at work and outside work. Adjusting for health, demographic and occupational factors explained many of these associations, but sleeping tablet use was independently associated with accidents (both at work and outside work), and antidepressant use with cognitive failures (outside work). CONCLUSIONS: Antidepressant and sleeping tablet use were apparently associated with accidents, minor injuries and cognitive failures. Although most of the associations could be accounted for by other factors the results suggested links between sleeping tablet use and accidents, and between antidepressant use and cognitive failures.
