Health behaviours in offshore workers: exploration of behavioural determinants using the Theoretical Domains Framework (TDF)

Abstract

Background Despite being a fitness-screened workforce, reports have highlighted a rising prevalence of obesity and chronic conditions in offshore workers [OWs]. Taking ownership of health, by engaging in healthy behaviours, is critical for those working in remote and hostile environments. Using the TDF, this qualitative study sought to explore OWs’ health behaviours from the perspectives of OWs and remote healthcare practitioners [RHCPs] to inform the development of behavioural intervention(s). Methods Sixteen OWs attending a training course, at a local facility, were recruited. Thirteen RHCPs who held membership with an independent academic organisation and had experience of working in the offshore industry were recruited to the study, via email, by the organisation’s secretary. The TDF was used to develop a semi-structured interview schedule. Telephone interviews were conducted, recorded electronically and transcribed by the researcher. Transcripts were coded independently, by the researcher and a health psychologist, to identify theoretical domains and agreed on by consensus. Results Health-related behaviours perceived as requiring change included: alcohol consumption, diet and physical activity. TDF domains identified as behavioural determinants comprised: knowledge; beliefs about consequences; intentions; goals; memory, attention and decision processes; environmental context and resources; social influences; emotion, and behavioural regulation. Conclusion Three health behaviours were identified as requiring behaviour change. A number of behavioural determinants, influencing enactment of these key health behaviours, were identified. Given the diverse needs of the offshore population, implementation of an intervention targeting multiple behaviours, and addressing key behavioural determinants, is warranted.
