No full textChronic generalized pain (CGP) as one of the diagnostic criteria of fibromyalgia is a common condition amongst the populations of Western Europe and the USA. The prevalence of CGP in these countries is 10.7-13.2%. The etiology of CGP is unclear; however, several findings suggest that this is a process of somatization that masks affective disorders. There have been no studies of the epidemiology of CGP in Russia. The study was undertaken to determine the prevalence of CGP in the Yekaterinburg adult population and to examine the relationship of CGP to its demographic characteristics and affective disorders. A ostal cross-sectional population survey was conducted. This covered 159 persons (54 males and 105 females) aged 27 to 75 years who had been randomly selected from the election lists of Yekaterinburg residents. A questionnaire was posted to each participant in order to reveal whether a respondent had experienced pain a month before, to define its location, duration, severity, and to evaluate psychoemotional disorders. The response rate was 75.5% (120 replies). The prevalence of CGP was 13.3%. There was no relationship of the sex of a respondent to CGP. The latter was shown to be associated with age. There was also its significant association with psychoemotional disorders. CGP is a common condition in the Yekateringburg population, which occurs in every 8 adult residents, more frequently in those aged above 43 years. The individuals who suffer from CGP exhibit a high level of psychological distress
Self-reported pain severity is associated with a history of coronary heart disease
No full textBackground: previous studies have found an association between chronic pain and cardiovascular (CV) mortality.Objective: to explore the relationship between the severity of pain and non-fatal CV disease.Methods: a total of 45,994 adults randomly selected from general practice registers in Manchester and Aberdeen were posted a survey, which included a Chronic Pain Grade questionnaire, pain manikin and questions about lifestyle and medical history. A single component measuring pain severity was extracted using factor analysis. Logistic regression was used to test for an association between quintiles of pain severity and a history of CV disease, adjusting for confounders.Results: of the 15,288 responders, 61% (n = 9357) reported pain for ≥1 day in the past month. Compared with the first (lowest) pain severity quintile, the fully adjusted odds ratio for heart attack in the second severity quintile was 1.25 (95% confidence interval 0.68, 2.30); third quintile: 1.65 (0.93, 2.94); fourth quintile: 1.76 (1.00, 3.11) and fifth (highest) quintile 2.47 (1.43, 4.28). Corresponding figures for angina (excluding heart attack) were: 1.79 (0.93, 3.45), 1.91 (1.00, 3.62), 1.03 (0.50, 2.11) and 3.17 (1.71, 5.85).Conclusion: a history of CV disease is reported more often in those with severe pain than would be expected by chance, even when adjusting for shared risk factors
Is musculoskeletal pain more common now than 40 years ago?: Two population-based cross-sectional studies
No full textTo test the hypothesis that the prevalence of specific musculoskeletal pain symptoms has increased over time in the northwest region of England. To meet this objective we have examined the difference in the prevalence of low back, shoulder and widespread pain between the 1950s and today using historical data collected by the Arthritis Research Campaign (arc). Methods. Two cross-sectional surveys conducted over 40 yr apart in the northwest region of England. The status of two regional pain sites and widespread pain was determined using interview and questionnaire responses, for the earlier and later studies respectively. Subjects were classified positively if they reported low back pain, shoulder pain or widespread pain on the day of the survey. Rates were standardized to the Greater Manchester population. Results. There were large differences in the prevalence of musculoskeletal pain between the two surveys. For all three symptoms examined prevalence increased from 2- to 4-fold between the two surveys. In both surveys low back pain was more common in women. Shoulder and widespread pain was less prevalent in women than in men in the earlier survey but by the time of the later survey women reported more pain at these sites. Conclusions. The prevalence of musculoskeletal pain is much higher than that reported over 40 yr ago. The change in prevalence is unlikely to be entirely due to the study design; other possible explanations such as the increased reporting or awareness of these symptoms is discussed. © The Author 2005.

Is the report of widespread body pain associated with long-term increased mortality? Data from the Mini-Finland health survey
No full textObjective. To determine whether an observation in a UK study, that persons with chronic widespread pain are at long-term increased risk of cancer mortality, can be replicated in a different setting. Methods. Subjects were participants aged ≥30 yrs in the Mini-Finland Health Survey conducted between 1979 and 1980. Information collected included prevalent pains at different joints throughout the body, demographic, anthropometric, lifestyle and occupational factors. During follow-up, until 1994, information on vital status and cause of death was obtained. Results. 7182 persons participated (89.8%). The prevalence of widespread body pain (pain at four or more sites) was 20% in females and 12% in males, and during follow-up there were a total of 1647 deaths. The risk of death was not elevated amongst those with widespread pain [relative risk (RR): 0.86; 95% confidence interval (CI): 0.74-1.00], and in particular, those with widespread pain were at a slightly lower risk of several disease-specific causes of death and cancer death (RR: 0.64; 95% CI: 0.46-0.91). Conclusions. This study of multiple pains has not confirmed a previous observation of an association between the reporting of widespread pain and subsequent increased risk of cancer death. Differences in the definitions used or, more probably, the population studied, in particular, a larger rural population with more multiple pains related to physical activity may account for the differences. © The Author 2006.

The role of workplace low-level mechanical trauma, posture and environment in the onset of chronic widespread pain
No full textBackground. We have recently demonstrated that individual psychosocial factors are important predictors of the onset of chronic widespread pain. It has been hypothesized that excessive mechanical exposure may also be associated with symptom onset, although this has not been formally examined. We therefore determined the relative contributions of individual psychosocial and work-related mechanical, posture and environment factors in symptom onset. Methods. We conducted a population-based prospective survey and identified 1658 adults aged 18-65 yr who were symptom-free. At baseline, detailed information was obtained on work-related mechanical and environment factors using validated instruments. Individual psychosocial features were also measured. Subjects free of chronic widespread pain at baseline were followed up at 12 and 36 months to identify those reporting the onset of new symptoms. Results. In all, 1445 (91%) returned the questionnaire at 12 months and 978 (89%) at 36 months. Of these, 81 and 92 respectively reported new chronic widespread pain. Symptom onset was predicted by workplace factors {pushing/pulling heavy weights [relative risk (RR) = 1.8, 95% confidence interval (CI) 1.1, 3.0]; repetitive movements of the wrists (RR = 1.8, 95% CI 1.2, 2.7); kneeling (RR 2.2, 95% CI 1.2, 4.1)} and individual factors [aspects of illness behaviour (RR 2.9, 95% CI 1.6, 5.3); somatic symptoms (RR = 1.9 95% CI 1.1, 3.3); fatigue (RR = 1.9, 95% CI 1.2, 3. 1); baseline pain symptoms (RR = 2.5, 95 % CI 1.6, 3.9)]. In multivariate analysis, pushing/pulling heavy weights, repetitive wrist movements, kneeling and other pain at baseline were associated with new-onset chronic widespread pain. However, the strongest predictor was a high score on the illness behaviour scale. Conclusion. This study provides only limited support for the hypothesis that low-level mechanical injury may be a risk factor for developing chronic widespread pain. The onset of chronic widespread pain appears to be multifactorial and is strongly predicted by individual psychosocial factors
Risk factors for persistent chronic widespread pain: A community-based study
No full textBackground. Chronic widespread pain is the cardinal clinical feature of the fibromyalgia syndrome, which, in the majority of clinic patients, is persistent. By contrast, in community-derived patients, pain is persistent in only half of the affected individuals, particularly those with psychological distress. Whether such distress is a consequence of the pain or a manifestation of a wider process of somatization which is associated with the persistence of pain is unclear. Objectives. We tested in a large, prospective, population-based study the hypothesis that features of somatization predict the persistence of chronic widespread pain. Methods. In all, 252 (13%) of 1953 adult subjects selected from a population register were classified as having chronic widespread pain based on a detailed questionnaire which included a pain drawing. The patients also completed a number of psychosocial instruments which measure features known to be associated with somatization. Two hundred and twenty-five (91%) of the patients were successfully followed up after 12 months and provided data on pain status using the same instruments. Results. In all, 126 (56%) patients reported chronic widespread pain at follow-up, 74 (33%) reported other pain and 25 (11%) reported no pain. Persistent chronic widespread pain was strongly associated with baseline test scores for high psychological distress and fatigue. In addition, these subjects were more likely to display a pattern of illness behaviour characterized by frequent visits to medical practitioners for symptoms which disrupt daily activities. The prevalence of persistent pain increased with the number of risk factors the subjects were exposed to. Conclusions. Although almost half of the cases of chronic widespread pain resolved within 1 yr, this study has demonstrated for the first time that those subjects who display features of somatization are more likely to have widespread pain which persists. These findings have implications for the identification and treatment of persons with persistent chronic widespread pain
The prevalence and associated features of chronic widespread pain in the community using the 'Manchester' definition of chronic widespread pain
No full textObjective. We examine the descriptive epidemiology of chronic widespread pain using the 'Manchester' definition [CWP(M)] and assess psychosocial and other features which characterize subjects with such pain according to these more stringent criteria. Methods. A population postal survey of 3004 subjects was conducted in the Greater Manchester area of the UK. Results. The point prevalence of Manchester-defined chronic widespread pain was 4.7%. CWP(M) was associated with psychological disturbance [risk ratio (RR) = 2.2, 95% confidence interval (CI) (1.4-3.5)], fatigue [RR = 3.8, 95% CI (2.3-6.1)], low levels of self-care [RR = 2.2, 95% CI (1.4-3.6)] and with the reporting of other somatic symptoms [RR = 2.0, 95% CI (1.3-3.1)]. Hypochondriacal beliefs and a preoccupation with bodily symptoms were also associated with the presence of CWP(M). Conclusion. This definition of chronic widespread pain is more precise in identifying subjects with truly widespread pain and its associated adverse psychosocial factors. Clear associations with other 'non-pain' somatic symptoms were identified, which further supports the hypothesis that chronic widespread pain is one feature of somatization
What characterizes persons who do not report musculoskeletal pain? Results from a 4-year population-based longitudinal study (the Epifund study)
No full textObjective. to identify and characterize persons in the population who do not report musculoskeletal pain.Methods. this was a population-based 4-year prospective longitudinal study by postal questionnaire. Population sample recruited from general practice registers in North-West England followed up at 15 months and 4 years.Results. of respondents, 17.4% [95% confidence interval (CI) 16.1%–19.7%] reported no pain in the previous month at all 3 measurement intervals over 4 years. They were characterized by low levels of psychological distress [relative risk (RR) low vs high levels of psychological distress 2.3; 95% CI 1.7–2.9], low levels of depression (2.7; 95% CI 2.0–3.6), low levels of anxiety (2.1; 95% CI 1.6–2.7), low health anxiety (1.6; 95% CI 1.2–2.1), and low illness behavior scores (5.8; 95% CI 4.0–8.3), good quality sleep (3.4; 95% CI 2.6–4.4), no somatic symptoms (RR 0 vs 3 or more, 3.1; 95% CI 1.6–6.3) and no adverse life events in the 6 months prior to baseline data collection (RR 0 vs 3 or more, 3.2; 95% CI 1.6–6.2). On multivariable analysis, good quality sleep, low illness behavior, low psychological distress, and absence of recent adverse life events remained statistically independent predictors of musculoskeletal health. In total, 46% of persons who had all 4 of these characteristics consistently reported being free of pain, compared to only 5% of those who had none.Conclusion. in a general population sample, over a period of 4 years, only around 1 in 6 persons do not report musculoskeletal pain. These persons report low levels of psychological distress and high quality sleep, both of which are potentially modifiable risk factors for the targeting of interventional or preventive strategies.<br/
Mechanical and psychosocial factors predict new onset shoulder pain: A prospective cohort study of newly employed workers
No full textAim: To test the hypothesis that work related mechanical and psychosocial factors predict new onset shoulder pain in newly employed workers. Methods: Two year prospective study of newly employed workers from 12 diverse occupational settings. At baseline, 1081 subjects provided information on work related mechanical and psychosocial risk factors, and current pain status. Results: In all, 803 (74%) subjects were free from shoulder pain at baseline. Of those, 638 (79%) responded at 12 months and 476 (88%) at 24 months. New onset shoulder pain was reported by 93 (15%) and 73 (15%) subjects respectively. An increased risk of symptom onset was found in subjects reporting mechanical exposures involving heavy weights including lifting with one or two hands, carrying on one shoulder, lifting at or above shoulder level, and pushing or pulling. Working with hands above shoulder level was also predictive of new onset shoulder pain. Of the psychosocial factors examined, the strongest predictor was monotonous work. Those individuals with any other previous pain also had an increased risk of new onset shoulder pain at follow up. In multivariate analysis, lifting heavy weights with one or two hands, pushing or pulling heavy weights, working with hands above shoulder level, and monotonous work were independently associated with new onset shoulder pain. Conclusions: This study supports the hypothesised relation between mechanical risk factors and shoulder pain. In general, work related psychosocial factors were modestly associated with new onset shoulder pain. However, monotonous work was a strong risk factor for new onset shoulder pain
