Traumatic and Non-traumatic Fibromyalgia Syndrome: Impact Assessment on the Life Quality of Women

The association between bullying victimization in childhood and fibromyalgia. Data from the nationwide Finnish health and social support (HeSSup) study based on a sample of 64,797 individuals

BACKGROUND

Fibromyalgia is a functional pain syndrome presenting with various psychological symptoms. Several studies have shown that adverse life events are associated with fibromyalgia. The aim of the current study is to explore the association between self-reported bullying victimization in childhood and self-reported fibromyalgia in adulthood.

METHODS

The basic study setting is cross-sectional - with focused use of retrospective data - derived from a large on-going postal follow up survey (sample N = 64,797) initiated in Finland in 1998. Only respondents having answered the questions on fibromyalgia in both follow ups in 2003 and 2012 were included (N = 11,924). Severity of bullying was divided into three groups starting from no bullying followed by minor and severe bullying. Covariates having shown statistically significant associations with fibromyalgia in cross tabulation using Pearson's chi-squared test were included in the final multiple logistic regression analyses.

RESULTS

In our study, 50.6% of the respondents reported victimization of minor and 19.6% of severe bullying in childhood. Participants reporting fibromyalgia in adulthood reported more bullying, and in females alone this association was statistically significant (p = .027). In multiple logistic regression analysis statistically significant associations between bullying victimization in childhood (reference: no bullying) and fibromyalgia were found: adjusted odds ratio (OR) for minor bullying was 1.35 (95% CI 1.09-1.67) and for severe bullying 1.58 (95% CI 1.21-2.06). However, in log-linear and logistic regression interaction models the association between bullying and fibromyalgia was not statistically significant when depression was included in the models.

CONCLUSIONS

Our results suggest that peer bullying victimization might be associated with fibromyalgia. However, in logistic log linear and logistic interaction models there was no statistically significant association when depression was included. As a result, there is need for further, preferably prospective cohort studies. The findings also emphasize the importance of actions to prevent childhood bullying.

Hypnosis is More Effective than Clinical Interviews

To determine whether hypnosis is more effective than conventional interviewing to find traumatic life events in patients with fibromyalgia, we carried out a within-subject experimental design with complete intragroup counterbalancing. Thirty-two women under care in a public primary care center gave 2 identical interviews, with an interval of 3 months, in which the occurrence of traumatic life events was explored, once in a state of wakefulness and once in a state of hypnosis. The state of consciousness was evaluated using 3 measures: bispectral index, skin conductance level, and pain intensity. In the hypnotic state, the patients expressed 9.8 times more traumatic life events than in the waking state, a statistically significant difference with a large effect size.

The relationship between childhood adversities and fibromyalgia in the general population

BACKGROUND

Fibromyalgia 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.

METHODS

HeSSup 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.

RESULTS

There 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).

CONCLUSION

All six enquired adversities were associated with fibromyalgia after adjustments. These findings emphasize the importance of preventing adverse childhood experiences.
