Objective: The purpose of the study is to evaluate health-related quality of life (HRQL), pain, the number of painful areas, and depression level; both to compare obesity level and these parameters, and to compare between obese and non-obese participants. Materials (Subjects) and Methods: 1875 voluntary patients were evaluated. Patients were grouped into 5 according to body mass index (BMI) values: Group 1:17-24.99kg/m2, Group 2:25-29.99kg/m2, Group 3:30-34.99kg/m2, Group 4:35-35.99kg/m2, Group 5: BMI more than 40kg/m2. Patients were asked to fulfill a questionnaire about demographic data and a number of painful areas (neck, shoulder, elbow, wrist, back, low back, knee, ankle, and temporomandibular joint). All patients were evaluated with visual analog scale (VAS), for pain, short form-36 (SF-36) for HRQL, Beck Depression Scale (BDS) for depression level. Results:We have included 1832 patients (460 male, and 1372 female) in the study: Group 1: 285(16%), Group 2: 623(34%), Group 3: 653(36%), Group 4: 190(10%), Group 5: 81(4%). When the groups was compared according to VAS scores during activity; all other groups was higher than group 1 (p<0.01). When the BDS scores were compared; depression levels were higher in group 5 than the other groups. When a number of painful areas were compared; groups 3,4,5 had higher values than groups 1,2, and group 2 had higher values than group 1 (p<0.001). Conclusion: This study evaluates pain level, the number of painful areas, physical HRQL, and depression levels of pre-obese and obese patients using VAS, BDS, and SF-36 scores and proves negative effects when compared to the healthy population. But this effect does not correlate with BMI levels.
