Associated factors of anxiety symptoms in nursesIt is believed that identification of specific factors predisposing the nurses to the development of anxiety symptoms would be helpful for further intervention.Therefore, in this study, potential factors including thoseof the demographic features, lifestyle, work conditions,job content and effort-reward imbalances were analyzedfor their association with the anxiety symptoms.Among all the demographic factors, chronic diseasesstood out as the strongest associated factor for anxietysymptoms in nurses (OR 1.541). In comparison withnurses who had no chronic illness, the prevalence ofanxiety symptoms in nurses with chronic medical conditions was 14.6% higher, reaching 55.4%. This might notbe surprising as there were many studies demonstratingthe association of chronic illness with mental disorders[47] or vice versa [48,49]. Life event was also related tothe anxiety symptoms, and nurses who have experiencedlife events had a higher prevalence of anxiety symptoms.In addition, nurses with higher educational backgrounds(junior college, bachelor degree or above) appeared tohave higher levels of anxiety than the nurses with lowereducational backgrounds (technical nursing school orlower). However, the latter two factors did not contribute significantly when other factors were considered inthe logistic analysis.
