RT Journal Article SR Electronic T1 Health behaviours of Australian fly-in, fly-out workers and partners during on-shift and off-shift days: an ecological momentary assessment study JF BMJ Open JO BMJ Open FD British Medical Journal Publishing Group SP e023631 DO 10.1136/bmjopen-2018-023631 VO 8 IS 12 A1 Amanda L Rebar A1 Kristie-Lee Alfrey A1 Benjamin Gardner A1 Corneel Vandelanotte YR 2018 UL http://bmjopen.bmj.com/content/8/12/e023631.abstract AB Objectives Fly-in, fly-out (FIFO) work involves long commutes, living on-site for consecutive days and returning home between shifts. This unique type of work requires constant transitioning between the roles and routines of on-shift versus off-shift days. This study aims to examine health behaviour patterns of FIFO workers and FIFO partners during on-shift and off-shift time frames.Design This study used ecological momentary assessment and multilevel modelling to examine daily health behaviours.Setting FIFO workers and FIFO partners from across Australia responded to daily online surveys for up to 7 days of on-shift and up to 7 days of off-shift time frames.Participants Participants included 64 FIFO workers and 42 FIFO worker partners.Results Workers and partners reported poorer sleep and nutrition quality for on-shift compared with off-shift days. Both workers and partners exercised less, smoked more cigarettes, took more physical health medication and drank less alcohol during on-shift compared with off-shift days.Conclusions FIFO organisations should consider infrastructure changes and support services to enhance opportunities for quality sleep and nutrition, sufficient exercise, moderate alcohol consumption and cigarette cessation for workers on-site and their partners at home.
