“…These covered a diverse range of interventions: changes to the speed, direction and use of rotation, changes to night work, later start and finish times, changes to weekend working, decreased shift lengths, and self-scheduling. One study was a crossover controlled trial, 29 and there were twenty prospective cohort studies, [25][26][27][30][31][32][33][34][35][36][37]39,41,42,[44][45][46][47][48][49][50] of which twelve had a control group. 25,26,30,31,33,36,37,41,42,[44][45][46][47] The cohort study controls were generally recruited from different sections of the same organisation (e.g.…”

“…Similarly, only six of the studies stated that they had adjusted for confounders: age, gender, shift work experience, lifestyle factors, or job content. 25,31,37,46,47,51 The majority of studies were conducted in fairly homogeneous populations (e.g. male production workers, or female nurses) and, perhaps in part due to this, only one study (a multiple intervention study of backward to forward rotation and slow to fast rotation) 50 differentiated outcomes by age, and none of the studies differentiated by socio-economic group or gender.…”

“…In the chemical processing study, 25,26 disturbance to social and family life improved when working the morning shifts, but there were no differences when on the afternoon or night shifts.

INTRODUCTIONShift work is an increasingly common form of work organisation. Around one fifth of workers are engaged in some kind of shift work. 1 Technological advances, changes in the economy, and the emergence of 24 hour societies 2,3 mean that shift work is no longer confined to the manufacturing and industrial sectors, and it is now an important aspect of employment in the retail and service sectors. Shift work continues to be commonplace amongst health care and emergency services personnel, with up to 50% of hospital staff working on shifts. 4 However, it remains socially patterned with a higher prevalence amongst lower socio-economic groups, 5 and so it is they who most experience the adverse consequences of shift work on health and work-life balance (WLB).Possible negative effects of shift work on health and WLB are well known. 1,[6][7][8] Reported health problems include sleep disturbances, fatigue, digestive problems, emotional problems and stress-related illnesses, as well as increases in general morbidity, and in sickness absence. 9 These problems may derive from disruption to physiological, psychological and social circadian rhythms. 6,7 Shift work, particularly that involving night work, disrupts the natural circadian rhythm as it requires people to be active at times when they would normally be sleeping and vice versa. 7 This leads to sleep problems (as natural alerting mechanisms such as the cortisol surge and temperature rise will interrupt sleep) as well as daytime functioning (wakefulness at night will be reduced by temperature drops and melatonin surges Most existing research emphasises the physiological changes which shift work induces, but shift work also involves significant social desynchronisation, involving working at times and on days that may make it difficult to maintain a balanced domestic and social life. 15 The Work Foundation defines work-life balance (WLB) as:"people having a measure of control over when, where and how they work. It is achieved when an individual"s right to a fulfilled life inside and outside paid work is accepted and respected as the norm to the mutual benefit of the individual, business and society". 16 It has been suggested that wor...

Extended shifts in ambulance work: influences on health

2002

View full text Add to dashboard Cite

Shiftwork is a major source of stress for many workers. This study highlights the role that organizational and psychosocial variables play in alleviating the negative health effects of 10‐ and 14‐h shifts. It examines the direct and mediated effects of coping strategies, social support and control of shifts on work/non‐work conflict and subjective health. Participants are 60 ambulance workers, aged 22 to 55 years. A structural equation model with good fit demonstrates complex effects of social support from various sources (supervisors, co‐workers and family), coping and control on work/non‐work conflict and subjective health. Conceptually, the research contributes to the development of a theoretical framework that can assist in explaining how key psychosocial and organizational variables influence the psychological and physical symptoms experienced by shiftworkers.
