<![CDATA[Highlights: This study analyzed the relationship between BMI and the herniation degree of lumbar HNP patients based on MRI. There was a significant relationship between BMI and the herniation degree in lumbar HNP patients. Abstract Introduction: Lumbar herniated nucleus pulposus (HNP) is a localized displacement of disc material through the intervertebral disc space that occurs in the lumbar segment of the spine. One of the factors associated with lumbar HNP is body mass index (BMI), which can affect the incidence and severity. This study aimed to determine the relationship between BMI and the degree of herniation in patients with lumbar HNP. Methods: This was an observational cross-sectional study of 62 medical records of patients with lumbar HNP who underwent magnetic resonance imaging (MRI) at Abdoel Wahab Sjahranie Regional Hospital, Samarinda, Indonesia, selected using purposive sampling. The statistical analysis used was Fisher’s exact test with a Monte Carlo approach and Spearman’s correlation test, both performed using the International Business Machines Corporation (IBM) Statistical Package for the Social Sciences (SPSS) version 25.0. Results: Most patients were aged 31-40 years old (27.4%) and female (53.2%). The BMI was mostly in the underweight-normal range (45.2%), and the degree of herniation was mostly Grade II/protrusion (53.2%). The relationship between BMI and herniation degree showed a p-value of 0.044, indicating a significant association (p<0.05). Conclusion: Body mass index was associated with the degree of herniation.]]>
