Incidence of musculoskeletal pain in adult Kuwaitis using the validated Arabic version of the WHO-ILAR COPCORD Core Questionnaire

BACKGROUND:The WHO-ILAR Community Oriented Program for Control of Rheumatic Diseases (COPCORD) primarily aims to estimate the burden of musculoskeletal symptoms/disorders. We estimated the incidence of musculoskeletal pain in the first community-based COPCORD study in Kuwait. SUBJECTS AND METHODS: The validated Arabic version of the WHO-ILAR COPCORD Core Questionnaire was used in a survey of 2500 randomly selected Kuwaiti households to assess the frequency of musculoskeletal pain, disability, and health-seeking behavior in adult Kuwaitis, Those subjects reporting no musculoskeletal pain were identified and followed-up for a period of one year by contacting them every 2 weeks. Once a respondent reported pain, an appointment to report to hospital was offered and the subject was examined by a rheumatologist using American College of Rheumatology (ACR) criteria. RESULTS: Of 5159 adults who were non-complainers in an earlier prevalence phase of the study, 3341 responded to phone calls (response rate of 65%). The incidence of musculoskeletal pain was 6.6% (95%CI, 3.4%9.7%). Age- and sex-adjusted incidence rates were 7.2% (95%Cl, 3.4%10.5%) for females and 6.1% (95%Cl, 3.1%-9.2%) for males. The incidence rate increased with increasing age, body mass index, and with being married. The common sites of pain were knee, low back and shoulder. CONCLUSION: The incidence of musculoskeletal pain among Kuwaiti adults is reported for the first time, Further studies adopting the same instrument in other communities are warranted to compare with our findings.
