The clinical factors associated with benefit finding of complementary medicine use in patients with back pain: A cross-sectional study with cluster analysis.

Background: Complementary and alternative medicine (CAM) use has been increasing.
Objective: To identify the factors associated with perceived benefit from CAM methods in back problems.
Methods: The study was conducted on patients who practiced any CAM methods due to complaints of back pain. Social-demographic properties, details of CAM methods employed were questioned. Severity of pain was measured by visual analog scale (VAS); benefits were evaluated by the Likert scale. Hierarchical cluster analysis was used to discover relationships among variables.
Results: In total, 500 patients (265 female, 235 male) were included in the study. Mostly used methods were herbal therapy (32%), balneotherapy (31%), cupping (19.4%) and massage-manipulation (19.2%). Of patients, 355 (71%) were satisfied. The variables associated with benefit finding were female gender, age, chronicity and severity of pain, high educational level, upper middle income status, use as a result of recommendation, dissatisfaction with conventional methods, residence in an urban area, non-herbal method use, being married, and social insurance (p < 0.005).
Conclusion: The majority of patients using CAM perceived benefits; in particular, women living in urban areas, highly educated, aged more than 40, who suffer from severe chronic back pain, may be more inclined to go to CAM therapists.
