Background:Obesity is closely linked with various health issues, including a higher incidence of back pain. The OBELIX study (Obesity Back Pain Evaluation Laparoscopic Bariatric Surgery and Imaging with X-ray and MRI) aims to explore how bariatric surgery affects the spine and back pain in obese patients. This abstract presents the baseline characteristics of the study participants, aiming to provide a foundation for future findings.
Methods: This prospective, controlled observational study includes morbidly obese patients (BMI ≥40 or ≥35 with comorbidities) who are candidates for bariatric surgery. Participants are split into two groups: those undergoing surgery (Group O) and those not opting for surgery (Group N). Baseline data encompass demographic information, BMI, waist circumference, pain scores, disability scores, initial physical activity levels, and imaging results. Furthermore blood samples will be analyzed for biomarkers and inflammatory mediators.
Results: The study enrolled 46 participants with an average age of 44.5 years, 63% of whom are female. The average BMI is 37.0 kg/m², highlighting the significant degree of obesity among participants. At baseline, 78% of participants reported experiencing low back pain, with a mean VAS (Visual Analog Scale) score of 6.2 and a mean ODI (Oswestry Disability Index) score of 20. These scores indicate moderate to severe levels of pain and disability, underscoring the profound impact of obesity on musculoskeletal health. Additional data blood analysis and on physical activity provide further context to the participants' health status at the start of the study.
Conclusions: Baseline data from the OBELIX trial underline the prevalence and severity of back pain among obese patients. These findings will be crucial for evaluating the impact of bariatric surgery on back pain and overall spinal health. The study is poised to offer significant insights into the interplay between obesity and musculoskeletal pain, informing future treatment strategies aimed at improving patient outcomes and quality of life.
