THU0558 Fibromyalgia Symptoms in A Sample of Lebanese Nurses: Prevalence and Predictive Factors

Background Nurses work in a physically and emotionnally stressful envirnment, which could lead to increased fibromyalgia symptoms. Objectives To estimate the prevalence of fibromyalgia symptoms in nurses from Hotel Dieu de France and North Center Hospitals and to determine predictive factors. Methods The study was conducted using a questionnaire distributed to all registered nurses working in the two hospitals in November 2014. For fibromyalgia screening, we used the validated French version of London fibromyalgia epidemiology study screening questionnaire (LFESSQ). The screening was considered positive if a subject met four criteria of pain and two criteria of fatigue items (LFESSQ-6). To estimate the positive predictive value of LFESSQ-6, a sample of nurses screened positive were then examined by a rheumatologist to clinically confirm the diagnosis of fibromyalgia. The prevalence of fibromyalgia in nursing was estimated by applying the positive predictive value to LFESSQ-positive subjects detected by the questionnaire. They were also asked about their demographics, their work environment, personal and family history, as well as the frequency of episodes of depressed mood through the Patient's Health Questionnaire-2 (PHQ-2). The statistical analysis was based on a logistic regression model used for the multivariate analysis to identify predictive factors of fibromyalgia. Results 485 questionnaires were distributed, with a response rate of 76.3%. 16.8% of the study sample met the criteria of LFESSQ-6. The subsequent rheumatology consultation confirmed the diagnosis of fibromyalgia in 57.14% of positively screened. Applying the positive predicted value in the nursing population, the prevalence of fibromyalgia was estimated of 9.6% using the screening by the LFESSQ -6. The factors that were significantly associated with a positive screening fibromyalgia were: the number of children and sports activities as protective factors on the one hand, and dissatisfaction with salary, lack of group cohesion, and the frequency of episodes of depressed mood as risk factors on the other hand Conclusions Our results suggest that fibromyalgia is prevalent in the nursing population. Some risk factors are modifiable: depression measured by the PHQ- 2, dissatisfaction with salary and a lack of group cohesion. Protective factors were the number of children and the sports activities. References White KP, Harth M, Speechley M, Ostbye T.
