“…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.…”

“…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.…”

“…29 Furthermore, whilst the interventions were often evaluated using a prospective controlled study designs, 25,26,30,31,33,36,37,41,42,44-47 these were usually not matched or randomised and in at least one case there were significant group differences at baseline. 25,26,30,32,33,36,37,41,42,[44][45][46] In addition, a sizeable number of studies reported concurrent (multiple) interventions. 33,[44][45][46][47][48][49][50][51] As noted earlier, this was the first systematic review of the effects of changing the organisation of shift work so we elected to include all studies regardless of sample size (or quality).…”

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...

Background: Night shift work is associated with cardiovascular disease, but its associations with cardiovascular disease biomarkers are unclear. We investigated these associations in a study of female nurses. Methods:We used data from the Nurses' Health Study II for total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, C-reactive protein (CRP), and fibrinogen. The sample sizes for our analysis ranged from 458 (fibrinogen) to 3574 (total cholesterol). From questionnaires, we determined the number of night shifts worked in the 2 weeks before blood collection and total years of rotating night shift work. We used quantile regression to estimate differences in biomarker levels by shift work history, adjusting for potential confounders.Results: Nurses working 1 to 4 recent night shifts had median HDL cholesterol levels 4.4 mg/dL (95% confidence interval [CI]: 0.3, 7.5) lower than nurses without recent night shifts. However, working ≥5 recent night shifts and years of rotating night shift work were not associated with HDL cholesterol. There was no association between recent night shifts and CRP, but median CRP levels were 0.1 (95% CI: 0.0, 0.2), 0.2 (95% CI: 0.1, 0.4), and 0.2 (95% CI: 0.0, 0.4) mg/L higher among nurses working rotating night shifts for 1 to 5, 6 to 9, and ≥10 years compared with nurses never working rotating night shifts. These associations were attenuated when excluding postmenopausal women and women taking statins. We observed no associations between night shift work and other biomarkers. Conclusions:We found suggestive evidence of adverse short-term and long-term effects of night shift work on select cardiovascular disease biomarkers.
