Background Fatigue is commonly reported in population surveys and has been identified in patients with health conditions as a key co-morbidity which makes remaining in work challenging. Such patients, however, rarely have access to programmes to help them manage their fatigue. Aims To quantify the relationship between fatigue, work impairment and health-related job loss. Methods We use data from the Health and Employment After Fifty study, a longitudinal study of people aged 50–64 years when recruited through general practices in England in 2013–14. During follow-up, fatigue was measured using the Fatigue Assessment Scale, work impairment was assessed using the Work Productivity and Activity Impairment scale, and changes in employment status were recorded. Results A total of 2743 participants were eligible for the current analysis; 23% satisfied criteria for being fatigued. People who were fatigued were less likely to have a partner, university degree, be physically active and were more likely to be obese. Their job was more likely to involve shifts, be perceived as insecure, have reported difficulties coping with job demands, and be unsatisfying. After adjustment for socio-economic, lifestyle and work-related factors, they were almost twice as likely to report both work impairment (relative risk 1.8; 95% confidence interval [CI] 1.6, 2.1) and future health-related job loss, although the latter effect was only in those with other morbidities (incidence rate ratio 1.96; 95% CI 1.03–3.72). Conclusions Providing evidence-based support for workers with health conditions who experience fatigue may have an important impact at a population level in terms of extending working lives.

Background Arm pain is common amongst working-aged adults and causes substantial work disability. The results of a population-based randomized controlled trial (the ARM trial) suggested that advice to remain active reduced disability after 6 months. Aims To verify ARM trial results amongst people in paid employment. Methods The ARM trial recruited adults with distal arm pain referred for physiotherapy and randomized equally to three groups: wait-listed for physiotherapy (advised to rest); wait-listed for physiotherapy (advised to remain active) or early physiotherapy. The primary outcome was absence of disability at 26 weeks. Secondary analyses were undertaken amongst participants in paid employment. Results Amongst 538 trial participants, 347 (64%) were in paid employment, mean age 46.1 years and 47% in manual work. Employed participants were randomized equally to the three arms. Amongst the 271 (78% workers with 26-week data), 43% of those advised to remain active were free from disability, as compared with 37% of those advised to rest. Forty per cent of those who waited for physiotherapy were disability-free as compared with 35% of those treated rapidly. Advice to rest was associated with lower chances of recovery amongst workers who lift/carry weights and those who believed work had caused their symptoms (P = 0.023). Conclusions Although not powered as a trial for workers only, our findings suggest that advising activity was as beneficial for people currently in paid work and may be superior to advice to rest in reducing disability. Addressing harmful beliefs about causation of symptoms has the potential to reduce disability. [ABSTRACT FROM AUTHOR]

Background Low back pain (LBP) is one of the most prevalent occupational health problems in industrialized countries. Little is known about the epidemiology of LBP in developing countries. Aims To determine the prevalence of LBP among Nepalese textile workers and to investigate the influence of exposure to mechanical and other factors on LBP reporting. Methods Interviewers completed questionnaires with study subjects, and work-related mechanical exposures were measured by self-completed questionnaires. Associations of LBP with mechanical factors and somatic symptoms were determined by logistic regression and reported as odds ratios (ORs) with 95% confidence intervals (CI). Results Nine hundred and thirty-eight workers took part, a participation rate of 92%. The 1 month period prevalence of LBP was 35% (n = 324), being higher in females than males (45% versus 28%; P < 0.001). Several work-related mechanical factors were associated with increased odds of reporting LBP: lifting heavy weights with one hand (OR 1.7; 95% CI 1.1–2.8), pushing weights (OR 1.6; 95% CI 1.2–2.3 and pulling weights (OR 1.6; 95% CI 1.1–2.1). No association was found with working posture. Strong associations were found for reporting one (OR 2.4; 95% CI 1.7–3.4) or two somatic symptoms (OR 2.7; 95% CI 1.4–5.1). On multivariable analysis, reporting of somatic symptoms (OR 2.8; 95% CI 1.5–5.4), female gender (OR 2.2; 95% CI 1.5–3.1) and increasing age were significantly associated with increased risk of reporting LBP (OR 1.7; 95% CI 1.2–2.5), but no associations were found with mechanical factors. Conclusions This study suggests that mechanical load may not be the leading cause of LBP and adds to evidence that psychological factors play an important role in LBP in non-industrialized countries.

Background: Colorectal cancer is a significant cause of death. Removal of precancerous adenomas, and early detection and treatment of cancer, has been shown to reduce the risk of death. The aim of this review and meta-analysis was to determine whether flexible sigmoidoscopy (FS) is an effective population screening method for reducing mortality from colorectal cancer. Methods: MEDLINE (1946 to December 2012) and Embase (1980-2012, week 15) were searched for randomized clinical trials in which FS was used to screen non-symptomatic adults from a general population, and FS was compared with either no screening or any other alternative screening methods. Meta-analysis was carried out using a random-effects Mantel-Haenzsel model. Results: Twenty-four papers met the inclusion criteria, reporting results from 14 trials. Uptake of FS was usually lower than that for stool-based tests, although FS was more effective at detecting advanced adenoma and carcinoma. FS reduced the incidence of colorectal cancer after screening, and long-term mortality from colorectal cancer, compared with no screening in a selected population. Compared with stool-based tests in a general population, FS was associated with fewer interval cancers. Conclusion: FS is efficacious at reducing colorectal cancer mortality compared with no screening. It is more effective at detecting advanced adenoma and carcinoma than stool-based tests. FS may be compromised by poorer uptake. Introduction of FS as a screening method should be done on a pilot basis in populations in which it is not currently used, and close attention should be paid to maximizing uptake. The relative risk of adverse events with FS compared with stool-based tests should be quantified, and its real-world effectiveness evaluated against the most effective stool-based tests.

Prevalence studies suggest that shoulder pain is very common (7–20%) in the adult population, though little is known about the severity and impact of such pain. Disability results, in part, from the restriction of movement and we therefore determined the frequency of restricted shoulder movement in individuals in a general population sample reporting shoulder pain and associated disability. In all, 232 individuals were interviewed about shoulder pain and related disability, and their range of shoulder movement in the following planes was measured: elevation, forward flexion, backward flexion, external rotation and internal rotation, together with the minimum difference achieved between the tip of a thumb and the spinous process of C7. In total, 48 (21%) subjects reported current pain and disability in one or both shoulders. Using receiver operating characteristic (ROC) analysis, cut-offs for restricted movements were selected at the point of maximal discrimination between painful and pain-free shoulders. There was considerable overlap in the distribution of range of movement, at all six sites, between these two groups. The highest positive predictive value for pain was observed in restriction of the thumb to cervical spine movement (53%), but this also had the lowest negative predictive value. By contrast, the highest negative predictive value was observed for restriction of external rotation (96%). Restriction in any plane was observed in 77% of those individuals with pain, but was also present in half of those without pain. In summary, most people with self-reported shoulder pain in the community do not have widespread restriction of movement. Reduction in external rotation was the most discriminatory, but it is necessary to examine movement in multiple planes to assess the true burden of shoulder pain in the community.
