“…Unsurprisingly, studies have found that prison officers have one of the highest rates of work-related stress, illness and injury of all occupational groups (Dugan, Farr, Namazi, et al, 2016;Global Prison Trends, 2016). The incidence of burnout and post-traumatic stress disorder is greater than that found in other safety-critical occupations (Denhof & Spinaris, 2013) and the risk of sleep disorders, depression, anxiety and suicidal ideation is also comparatively high (James, Todak, & Best, 2017;Kinman, Clements, & Hart, 2016;Walker, Jackson, & Egan, 2015). Research conducted with correctional staff in several countries has found that negative health behaviours, such as low physical activity, poor diet and problem drinkin,g are particularly common and they are at particular risk of cardiovascular disease, stomach ulcers and musculoskeletal disorders (Campos, Schneider, Bonafe et al, 2016;Ferraro, Faghri, Henning, et al, 2013;Harenstam, Palm, & Theorell, 1988;Morse, Dussetschleger, Warren et al, 2011).…”
