Pain and associated functional impairment in the Danish general population: the role of mental well-being

PurposePrior research on relations between mental health and pain has focused on negative mental health aspects (e.g. depression), while the literature is scarce in terms of positive aspects, such as mental well-being. This study aims to investigate prospective associations of mental well-being at baseline with pain and functional impairment due to pain in the following year.Design/methodology/approachData stem from a Danish nationally representative survey of 5,000 adults (aged 15+) conducted in 2019 and 2020, which was linked to register data. The Short Warwick-Edinburgh Mental Well-being Scale was used to assess mental well-being, both continuously (range 7-35) and categorically (low, moderate, high). Logistic regressions were conducted to assess associations between mental well-being in 2019 and pain and functional impairment due to pain (among those reporting any pain) in 2020.FindingsIn the fully adjusted models, each point increase in mental well-being was inversely associated with pain (OR = 0.97, 95%CI 0.95-0.99) and functional impairment due to pain (OR = 0.96, 95%CI 0.94-0.99). As compared to low mental well-being, moderate mental well-being was associated with an OR of 0.76 (95%CI 0.58-0.99) for pain and an OR of 0.63 (95%CI 0.46-0.87) of functional impairment due to pain, while high mental well-being was associated with an OR of 0.56 (95%CI 0.40-0.77) for pain and an OR of 0.53 (95%CI 0.34-0.79) for functional impairment due to pain.Originality/valueHigher mental well-being levels may be protective against pain and functional impairment due to pain. Wider mental health promotion may be considered to prevent pain and associated functional impairments in the general population.
