Objective: The aim of this study is to determine the effects of obesity on physical performance, disability, quality of life, pain, balance and functional mobility in patients with chronic low back pain. Materials and Methods: 102 cases between the ages of 18-65 were included in the study. Cases It is divided into three groups according to Body Mass Index (BMI) (normal weight (group I), overweight (group II), obese (groupIII)). Physical Performance Test Battery (PPTB), Oswestry Disability Questionnaire (ODQ), Short Form- 36 (SF-36), Visual Analogue Scale (VAS) and Time Up and Go Test were administered to all patients. Results: A significant difference was found between group III and group I in the parameters of 5 min walking and weight forward reaching from PPTB parameters (p<0.05). Among the groups, no significant difference was found in the lumbar flexion range of motion, 50 steps of walking, 5 repeated of chair sit-stand and 10 repeated of trunk flexion from PPTB parameters (p>0.05). There was no difference between the groups in ODQ data (p>0.05). In the 8 subparameters of SF-36 no difference was found between the groups (p>0.05), however there was a negative correlation between BMI and physical function parameter of SF-36 (r=-,231 p<0.05). There was a significant difference between group III and group I and between group I and group II in timed up and go test (p<0.05). There was no difference in VAS data between the groups (p>0.05). Conclusion: Obesity in patients with chronic low back pain negatively affects physical performance, physical function, balance and functional mobility, but does not affect the pain severity and disability.
