The association between prevalent neck pain and health-related quality of life: a cross-sectional analysis

Abstract

The aim of this study was to examine the association between grades of neck pain severity and health-related quality of life (HRQoL), using a populationbased, cross-sectional mailed survey. The literature suggests that physical and mental HRQoL is worse for individuals with neck pain compared to those without neck pain. However, the strength of the association varies across studies. Discrepancies in study results may be attributed to the use of different definitions and measures of neck pain and differences in the selection of covariates used as control variables in the analyses. The Saskatchewan Health and Back Pain Survey was mailed to 2,184 randomly selected Saskatchewan adults of whom 1,131 returned the questionnaire. Neck pain was measured with the Chronic Pain Questionnaire and categorized into four increasing grades of severity. We measured HRQoL with the SF-36 Health Survey and computed the physical and mental component summary scores. We built separate multiple linear regression models to examine the association between grades of neck pain and physical and mental summary scores while controlling for sociodemographic, general health and comorbidity covariates. Our crude analysis suggests that a gradient exists between the severity of neck pain and HRQoL. Compared to individuals without neck pain, those with Grades III-IV neck pain have significantly lower physical (mean difference = -13.9/100; 95% CI = -16.4, -11.3) and mental (mean difference = -10.8/100; 95% CI = -13.6, -8.1) HRQoL. Controlling for covariates greatly reduced the strength of association between neck pain and physical HRQoL and accounted for the observed association between neck pain and mental HRQoL. In the comorbidity model, the strength of association between Grades III-IV neck pain and PCS decreased by more than 50% (mean difference = -4.5/ 100; 95% CI = -6.9, -2.0). In the final PCS model, Grades III-IV neck pain coefficients changed only slightly from the comorbidity model (mean difference = -4.4/ 100; 95% CI = -6.9, -1.9). This suggests that comorbid conditions account for most of the association between neck pain and PCS score. It was concluded that prevalent neck pain is weakly associated with physical HRQoL, and that it is not associated with mental HRQoL. Our crosssectional analysis suggests that most of the observed association between prevalent neck pain and HRQoL is attributable to comorbidities.

“…Regarding the relationship between neck pain and physical health-related QOL (HRQOL) in large population-based cohort studies, Nolet et al [67] reported that neck pain was associated with worse physical HRQOL, and Rezai et al [68] reported that neck pain was weakly associated with physical HRQOL and that comorbid conditions accounted for most of the association between neck pain and physical HRQOL.…”

The Association Between Self-Reported Cardiovascular Disorders and Troublesome Neck Pain: A Population-Based Cohort Study

“…21 The questionnaire has been shown to be reliable and valid in various populations with good internal consistency (α coefficients, N.85). 9,20,22,23 Exercise. Exercise frequency was measured with a question asking the average number of days per week participating in a minimum of 30 minutes of exercise.…”

“…The Comorbidity Questionnaire has been shown to have good test-retest reliability (intraclass correlation coefficient, 0.93) and adequate face, concurrent, and convergent validity. 9,10 Outcome Troublesome neck pain in the past 6 months was measured with the Chronic Pain Questionnaire at 6 and 12 months of follow-up. The questionnaire is used to grade neck pain and its related disability into 5 ordered categories.…”

The association between self-reported low back pain and lower limb disability as well as the association between neck pain and upper limb disability

“…[2] Neck pain and LBP are associated with significant disability and comorbidities, which can significantly affect quality of life. [2,3] Upper limb disability is a common musculoskeletal condition and its prevalence has been reported as 20% to 70% in the working population. [4,5] Upper limb disability can occur because of many clinical conditions such as neck problems.…”
