The relationship between childhood adversities and fibromyalgia in the general population

•Various adversities are linked to the onset of fibromyalgia. However, the association of childhood adversities and fibromyalgia is disputed.•The study population is based on a large cohort, which is a sample of the working-age Finnish population.•The use of self-reported adversities captures the emotional importance of childhood events.•Findings of our study suggest that there are associations between childhood adversities and fibromyalgia, although they are relatively weak.

BackgroundFibromyalgia is a syndrome characterized by widespread pain and a variety of somatic symptoms. The international prevalence of fibromyalgia is 2-5%, but its current prevalence in Finland is unclear. Various adversities are linked to the onset of fibromyalgia. However, there is need for more data regarding the association between childhood physical abuse and fibromyalgia. Further, the association of childhood emotional stressors and fibromyalgia is disputed. The aim of the current study is to produce more information about that relationship using data from the Health and Social Support (HeSSup) Study.MethodsHeSSup is a postal study consisting of a random sample of the Finnish population. The study setting is cross-sectional. Participants in the study were asked if they have been diagnosed with fibromyalgia. Those responding affirmatively were classified as fibromyalgia patients. Six childhood adversities were enquired, and the relationship between fibromyalgia and these events were analysed by cross tabulation and logistic regression.ResultsThere were associations between examined adversities and fibromyalgia before and after adjustments for demographic features and depression (being afraid of a family member: odds ratio after adjustment 1.60, 95% CI 1.28-2.01; long-lasting financial difficulties 1.45, 1.18-1.77; serious conflicts in the family 1.40, 1.14-1.72; parental divorce 1.34, 1.05-1.72; serious or chronic illnesses in the family 1.27, 1.05-1.55; alcohol problems in the family 1.25, 1.02-1.53).ConclusionAll six enquired adversities were associated with fibromyalgia after adjustments. These findings emphasize the importance of preventing adverse childhood experiences.
