  • Musculoskeletal pain is associated with very low levels of vitamin D in men: results from the European Male Ageing Study
  • 2010

    • Introduction A study was undertaken to test the hypothesis that musculoskeletal pain is associated with low vitamin D levels but the relationship is explained by physical inactivity and/or other putative confounding factors. Methods Men aged 40-79 years completed a postal questionnaire including a pain assessment and attended a clinical assessment (lifestyle questionnaire, physical performance tests, 25-hydroxyvitamin D3 (25-(OH) D) levels from fasting blood sample). Subjects were classified according to 25-(OH) D levels as 'normal' (>= 15 ng/ml) or 'low' (<15 ng/ml). The relationship between pain status and 25-(OH) D levels was assessed using logistic regression. Results are expressed as ORs and 95% CIs. Results 3075 men of mean (SD) age 60 (11) years were included in the analysis. 1262 (41.0%) subjects were pain-free, 1550 (50.4%) reported 'other pain' that did not satisfy criteria for chronic widespread pain (CWP) and 263 (8.6%) reported CWP. Compared with patients who were pain-free, those with 'other pain' and CWP had lower 25-(OH) D levels (n = 239 (18.9%), n = 361 (23.3) and n = 67 (24.1%), respectively, p < 0.05). After adjusting for age, having 'other pain' was associated with a 30% increase in the odds of having low 25-(OH) D while CWP was associated with a 50% increase. These relationships persisted after adjusting for physical activity levels. Adjusting for additional lifestyle factors (body mass index, smoking and alcohol use) and depression attenuated these relationships, although pain remained moderately associated with increased odds of 20% of having low vitamin D levels. Conclusions These findings have implications at a population level for the long-term health of individuals with musculoskeletal pain.

  • Perturbed Insulin-like Growth Factor-1 (IGF-1) and IGF Binding Protein-3 Are Not Associated with Chronic Widespread Pain in Men: Results from the European Male Ageing Study.
  • 2009
  • Ingår i: Journal of Rheumatology. - : The Journal of Rheumatology. - 0315-162X .- 1499-2752. ; 36, s. 2523-2530

    • OBJECTIVE: To determine whether perturbations of insulin-like growth factor-1 (IGF-1) and IGF binding protein-3 (IGFBP-3) were associated with the presence of chronic widespread pain (CWP) in men. METHODS: The European Male Ageing Study (EMAS) is an 8-center population-based study of men aged 40-79 years recruited from population registers. A questionnaire asked about the presence and duration of musculoskeletal pain, from which subjects reporting CWP were identified. Subjects also had an interviewer-assisted questionnaire: levels of physical activity and mood were assessed, and height and weight were measured. IGF-1 and IGFBP-3 were assayed from a fasting blood sample. Logistic regression models were used to determine the association between IGF measures and CWP. Results were expressed as odds ratios or relative risk ratios. RESULTS: A total of 3206 subjects provided full data. Of those, 1314 (39.0%) reported no pain in the past month and 278 (8.3%) reported pain that satisfied criteria for CWP. IGF-1 concentrations were similar among subjects who reported no pain and those with CWP: 131.5 mg/l and 128.4 mg/l, respectively. This was true also for IGFBP-3 (4.3 and 4.3 mg/l). Obesity was associated with low IGF-1 and a high IGFBP-3/IGF-1 ratio, indicating less bioavailable IGF-1, irrespective of pain status. This relationship persisted after adjustment for comorbidities, depression, smoking, alcohol consumption, and quality of life. CONCLUSION: Overall CWP was not associated with perturbations in IGF-1 and IGFBP-3 concentrations. Hypofunctioning of the axis was noted among subjects who were obese and this was not specific to CWP. These data suggest that IGF-1 is unlikely to be etiologically important in relation to CWP, although the relationship with growth hormone remains to be elucidated.

  • Elevated levels of gonadotrophins but not sex steroids are associated with musculoskeletal pain in middle-aged and older European men
  • 2011
  • Ingår i: Pain. - : Ovid Technologies (Wolters Kluwer Health). - 1872-6623 .- 0304-3959. ; 152:7, s. 1495-1501

    • The aim of this study was to determine the association of hormone levels with the occurrence of musculoskeletal pain. Men ages 40 to 79 years were recruited from population registers in 8 European centres. Subjects were asked to complete a postal questionnaire, which enquired about lifestyle and the occurrence of musculoskeletal pain over the past month. Total testosterone (T), oestradiol (E2), luteinising hormone (LH), and follicle-stimulating hormone (FSH) were assayed from a fasting blood sample. The association between pain status and hormone levels was assessed using multinomial logistic regression with results expressed as relative risk ratios (RRR) and 95% confidence intervals (CI). A total of 3206 men had complete data on pain status. Of these, 8.7% reported chronic widespread pain (CWP), whereas 50% had some pain although not CWP and were classified as having some pain. T and E2 were not associated with musculoskeletal pain, whereas significant differences in LH and FSH levels were found between pain groups. After adjustment for age and other possible confounders, the association between pain status and both LH and FSH persisted. Compared with those in the lowest tertile of LH, those in the highest tertile were more likely to report some pain (vs no pain, RRR = 1.28; 95% CI 1.09 to 1.50) and also CWP (vs no pain, RRR = 1.51; 95% CI 1.10 to 2.07). Similar results were found for FSH. Gonadotrophins, but not sex steroid hormone levels, are associated with musculoskeletal pain in men. (C) 2011 International Association for the Study of Pain.

  • The Effect of Musculoskeletal Pain on Sexual Function in Middle-aged and Elderly European Men: Results from the European Male Ageing Study.
  • 2011
  • Ingår i: Journal of Rheumatology. - : The Journal of Rheumatology. - 0315-162X .- 1499-2752. ; 38, s. 370-377

    • OBJECTIVE: To determine whether musculoskeletal pain was associated with impaired sexual function in a population sample of middle-aged and older men. METHODS: The European Male Ageing Study (EMAS), a multicenter population-based study of men aged 40-79 years, was used to investigate this hypothesis. A questionnaire asked about the presence and duration of musculoskeletal pain, allowing subjects to be classified into 1 of 3 groups: those reporting chronic widespread pain (CWP), those reporting pain but not CWP ("some pain"), and those with no pain. Subjects completed a sexual function questionnaire from which 3 domains were considered: overall sexual functioning (OSF), sexual functioning-related distress (SFD), and change in sexual functioning compared to 1 year ago (CSF). RESULTS: A total of 3206 men [mean age 60 (SD 11) yrs] had complete data on pain status. Of these, 8.7% had CWP and 50.34% had "some pain." Pain was associated with lower OSF, and higher SFD and CSF scores. After adjustment for putative confounding factors, the associations became non-significant with OSF and CSF but persisted for SFD. Associations between pain status and some items within the sexual functioning domains, including frequency of sexual intercourse, frequency of morning erections, sexual desire, and orgasm were also significant, although these associations varied by pain status. CONCLUSION: Musculoskeletal pain is associated with several aspects of sexual functioning. These relationships differ depending on the extent of the pain (chronic or not) and are also largely confounded by other health-related factors, primarily depression.
