(BMJ Pub. Group., 2020) Coggon, D.; Ntani, G.; Walker-Bone, K.; Felli, V.E.; Harari, R.; Barrero, L.H.; Felknor, S.A.; Rojas, M.; Cattrell, A.; Serra, C.; Bonzini, M.; Solidaki, E.; Merisalu, E.; Habib, R.R.; Sadeghian, F.; Kadir, M.M.; Wickremasinghe, A.R.; Matsudaira, K.; Nyantumbu-Mkhize, B.; Kelsall, H.L.; Harcombe, H.
OBJECTIVES: To explore the association of sickness absence ascribed to pain at specific anatomical sites with wider propensity to musculoskeletal pain. METHODS: As part of the CUPID (Cultural and Psychosocial Influences on Disability) study, potential risk factors for sickness absence from musculoskeletal pain were determined for 11 922 participants from 45 occupational groups in 18 countries. After approximately 14 months, 9119 (78%) provided follow-up information about sickness in the past month because of musculoskeletal pain, including 8610 who were still in the same job. Associations with absence for pain at specific anatomical sites were assessed by logistic regression and summarised by ORs with 95% CIs. RESULTS: 861 participants (10%) reported absence from work because of musculoskeletal pain during the month before follow-up. After allowance for potential confounders, risk of absence ascribed entirely to low back pain (n=235) increased with the number of anatomical sites other than low back that had been reported as painful in the year before baseline (ORs 1.6 to 1.7 for ≥4 vs 0 painful sites). Similarly, associations with wider propensity to pain were observed for absence attributed entirely to pain in the neck (ORs up to 2.0) and shoulders (ORs up to 3.4). CONCLUSIONS: Sickness absence for pain at specific anatomical sites is importantly associated with wider propensity to pain, the determinants of which extend beyond established risk factors such as somatising tendency and low mood. Better understanding of why some individuals are generally more prone to musculoskeletal pain might point to useful opportunities for prevention.

Classification of neck/shoulder pain in epidemiological research: a comparison of personal and occupational characteristics, disability and prognosis among 12,195 workers from 18 countries
(Elsevier-North-Holland, 2016) Sarquis, L.M.; Coggon, D.; Ntani, G.; Walker-Bone, K.; Palmer, K.T.; Felli, V.E.; Harari, R.; Barrero, L.H.; Felknor, S.A.; Gimeno, D.; Cattrell, A.; Vargas-Prada, S.; Bonzini, M,; Solidaki, E.; Merisalu, E.; Habib, R.R.; Sadeghian, F.; Kadir, M.M.; Warnakulasuriya, S.S.; Matsudaira, K.; Nyantumbu, B.; Sim, M.R.; Harcombe, H.; Cox, K.; Marziale, M.H.; Harari, F.; Freire, R.; Harari, N.; Monroy, M.V.; Quintana, L.A.; Rojas, M.; Harris, E.C.; Serra, C.; Martinez, J.M.; Delclos, G.; Benavides, F.G.; Carugno, M.; Ferrario, M.M.; Pesatori, A.C.; Chatzi, L.; Bitsios, P.; Kogevinas, M.; Oha, K.; Tiina; Freimann; Sadeghian, A.; Peiris-John, R.J.; Sathiakumar, N.; Wickremasinghe, A.R.; Yoshimura, N.; Kelsall, H.L.; Hoe, V.C.; Urquhart, D.M.; Derrett, S.; McBride, D.; Herbison, P.; Gray, A.; Salazar Vega, E.J.
To inform case-definition for neck/shoulder pain in epidemiological research, we compared levels of disability, patterns of association and prognosis for pain that was limited to the neck or shoulders (LNSP) and more generalised musculoskeletal pain that involved the neck or shoulder(s) (GPNS). Baseline data on musculoskeletal pain, disability and potential correlates were collected by questionnaire from 12,195 workers in 47 occupational groups (mostly office workers, nurses, and manual workers) in 18 countries (response rate = 70%). Continuing pain after a mean interval of 14 months was ascertained through a follow-up questionnaire in 9,150 workers from 45 occupational groups. Associations with personal and occupational factors were assessed by Poisson regression and summarised by prevalence rate ratios (PRRs). The one-month prevalence of GPNS at baseline was much greater than that of LNSP (35.1% vs. 5.6%), and it tended to be more troublesome and disabling. Unlike LNSP, the prevalence of GPNS increased with age. Moreover, it showed significantly stronger associations with somatising tendency (PRR 1.6 vs. 1.3) and poor mental health (PRR 1.3 vs. 1.1); greater variation between the occupational groups studied (prevalence ranging from 0% to 67.6%) that correlated poorly with the variation in LNSP; and was more persistent at follow-up (72.1% vs. 61.7%). Our findings highlight important epidemiological distinctions between sub-categories of neck/shoulder pain. In future epidemiological research that bases case definitions on symptoms, it would be useful to distinguish pain which is localised to the neck or shoulder from more generalised pain that happens to involve the neck/shoulder region.
Descriptive Epidemiology of Somatising Tendency: Findings from the CUPID Study
(Public Library of Science, 2016) Vargas-Prada, S.; Coggon, D.; Ntani, G.; Walker-Bone, K.; Palmer, K.T.; Felli, V.E.; Harari, R.; Barrero, L.H.; Felknor, S.A.; Gimeno, D.; Cattrell, A.; Bonzini, M.; Solidaki, E.; Merisalu, E.; Habib, R.R.; Sadeghian, F.; Kadir, M.M.; Warnakulasuriya, S.S.; Matsudaira, K.; Nyantumbu, B.; Sim, M.R.; Harcombe, H.; Cox, K.; Sarquis, L.M.; Marziale, M.H.; Harari, F.; Freire, R.; Harari, N.; Monroy, M.V.; Quintana, L.A.; Rojas, M.; Harris, E.C.; Serra, C.; Martinez, J.M.; Delclos, G.; Benavides, F.G.; Carugno, M.; Ferrario, M.M.; Pesatori, A.C.; Chatzi, L.; Bitsios, P.; Kogevinas, M.; Oha, K.; Freimann, T.; Sadeghian, A.; Peiris-John, R.J.; Sathiakumar, N.; Wickremasinghe, A.R.; Yoshimura, N.; Kelsall, H.L.; Hoe, V.C.; Urquhart, D.M.; Derrett, S.; McBride, D.; Herbison, P.; Gray, A.; Vega, E.J.
Somatising tendency, defined as a predisposition to worry about common somatic symptoms, is importantly associated with various aspects of health and health-related behaviour, including musculoskeletal pain and associated disability. To explore its epidemiological characteristics, and how it can be specified most efficiently, we analysed data from an international longitudinal study. A baseline questionnaire, which included questions from the Brief Symptom Inventory about seven common symptoms, was completed by 12,072 participants aged 20-59 from 46 occupational groups in 18 countries (response rate 70%). The seven symptoms were all mutually associated (odds ratios for pairwise associations 3.4 to 9.3), and each contributed to a measure of somatising tendency that exhibited an exposure-response relationship both with multi-site pain (prevalence rate ratios up to six), and also with sickness absence for non-musculoskeletal reasons. In most participants, the level of somatising tendency was little changed when reassessed after a mean interval of 14 months (75% having a change of 0 or 1 in their symptom count), although the specific symptoms reported at follow-up often differed from those at baseline. Somatising tendency was more common in women than men, especially at older ages, and varied markedly across the 46 occupational groups studied, with higher rates in South and Central America. It was weakly associated with smoking, but not with level of education. Our study supports the use of questions from the Brief Symptom Inventory as a method for measuring somatising tendency, and suggests that in adults of working age, it is a fairly stable trait.

STUDY DESIGN: Cross-sectional survey with longitudinal follow-up OBJECTIVES.: To test the hypothesis that pain which is localised to the low back differs epidemiologically from that which occurs simultaneously or close in time to pain at other anatomical sites SUMMARY OF BACKGROUND DATA.: Low back pain (LBP) often occurs in combination with other regional pain, with which it shares similar psychological and psychosocial risk factors. However, few previous epidemiological studies of LBP have distinguished pain that is confined to the low back from that which occurs as part of a wider distribution of pain. METHODS: We analysed data from CUPID, a cohort study that used baseline and follow-up questionnaires to collect information about musculoskeletal pain, associated disability and potential risk factors, in 47 occupational groups (office workers, nurses and others) from 18 countries. RESULTS: Among 12,197 subjects at baseline, 609 (4.9%) reported localised LBP in the past month, and 3,820 (31.3%) non-localised LBP. Non-localised LBP was more frequently associated with sciatica in the past month (48.1% vs. 30.0% of cases), occurred on more days in the past month and past year, was more often disabling for everyday activities (64.1% vs. 47.3% of cases), and had more frequently led to medical consultation and sickness absence from work. It was also more often persistent when participants were followed up after a mean of 14 months (65.6% vs. 54.1% of cases). In adjusted Poisson regression analyses, non-localised LBP was differentially associated with risk factors, particularly female sex, older age and somatising tendency. There were also marked differences in the relative prevalence of localised and non-localised LBP by occupational group. CONCLUSIONS: Future epidemiological studies should distinguish where possible between pain that is limited to the low back and LBP which occurs in association with pain at other anatomical locations.
Patterns of change of multisite pain over one year of follow-up and related risk factors
(Philadelphia : Saunders, London, 2022) Ntani, G.; Coggon, D.; Felli, V.E.; Harari, F.; Barrero, L.H.; Felknor, S.A.; Rojas, M.; Serra, C.; Bonzini, M.; Merisalu, E.; Habib, R.R.; Sadeghian, F.; Wickremasinghe, A.R.; Matsudaira, K.; Nyantumbu-Mkhize, B.; Kelsall, H.L.; Harcombe, H.; Walker-Bone, K.
Background: Multisite musculoskeletal pain is common and disabling. This study aimed to prospectively investigate distribution of musculoskeletal pain anatomically, and explore risk factors for increases/reductions in the number of painful sites. Methods: Using data from participants working in 45 occupational groups in 18 countries, we explored changes in reporting pain at 10 anatomical sites on two occasions 14 months apart. We used descriptive statistics to explore consistency over time in the number of painful sites, and their anatomical distribution. Baseline risk factors for increases/reductions by ≥3 painful sites were explored by random intercept logistic regression that adjusted for baseline number of painful sites. Results: Amongst 8,927 workers, only 20% reported no pain at either time point, and 16% reported ≥3 painful sites both times. After 14 months, the anatomical distribution of pain often changed but there was only an average increase of 0.17 painful sites. Some 14% workers reported a change in painful sites by ≥ 3. Risk factors for an increase of ≥ 3 painful sites included female sex, lower educational attainment, having a physically demanding job, and adverse beliefs about the work-relatedness of musculoskeletal pain. Also predictive were: older age, somatising tendency, and poorer mental health (each of which was also associated with lower odds of reductions of ≥ 3 painful sites). Conclusions: Longitudinally, the number of reported painful sites was relatively stable but the anatomical distribution varied considerably. These findings suggest an important role for central pain sensitisation mechanisms, rather than localised risk factors, among working adults.
