Relationship between Body Mass Index and Radiological Features of Spondylolisthesis

Background: Low back pain is the most common cause of spondylolisthesis. The prevalence of degenerative spondylolisthesis is very gender- and age-specific. For elderly showed degenerative spondylolisthesis was 25% in women and 19.1% in men. The female: male prevalence ratio was 1.3:1. Overweight BMI might lead to an increased axial load of the L4–L5 disc and facet joints, and enhance the risk of degenerative spondylolisthesis. Method: This analytical observational study used cross-sectional design to analyze the effect of BMI on radiological features of spondylolisthesis in lumbosacral vertebral photos in female patients over 50 years of age with low back pain. Result: The sample used in this study was 72 consisting of 59 patients (81.9%) with normal BMI and 13 patients (18.1%) with overweight BMI, and 39 patients with positive spondylolisthesis (54.2%) and 33 patients (45.8%) with negative spondylolisthesis. The chi-square test results obtained a significance value of 0.015 (p less than0.05) with the odds ratio obtained at 6.089. Conclusion: The results of data analysis proved that BMI significantly influenced the radiological features of spondylolisthesis in lumbosacral vertebral photos in patients who had overweight BMI having a greater risk of 6.089 times spondylolisthesis than patients who had normal BMI.
