Does Metabolic Syndrome Determine Severity and Disability of Chronic Low Backache?

Abstract

ABSTRACT Introduction: Obesity may be associated with more severe and disabling low backache (LBA) due to alteration in biomechanics, but there are no such studies from developing countries. Aims: We report the frequency of metabolic syndrome (MS) in chronic LBA (CLBA) and its association with severity and disability of CLBA. Subjects and Methods: Consecutive patients with CLBA attending to the neurology service from October 2015 to February 2016 were included in the study. Clinical and demographic parameters were recorded. Routine biochemical test was done. The severity of pain was assessed by a 0–10 Numeric Rating Scale (NRS) and disability by Oswestry Disability Index (ODI) version 2. Comparison of variables was done by Chi-square or independent t-test and correlation by Karl Pearson or Spearman's rank correlation test. Results: Seventy-none (39.3%) patients had MS as per the International Diabetic Federation (IDF) criteria and 68 (33.8%) as per the National Cholesterol Education Program Adult Treatment Panel III criteria. Abdominal obesity was the most common (171 [85.1%]) feature of MS. The patients with MS had longer duration of sitting work and did less frequently exercise. The NRS score (6.95 ± 1.06 vs. 6.65 ± 0.95; P = 0.04) and ODI score (54.91 ± 8.42 vs. 51.89 ± 8.54; P = 0.01) were higher in CLBA patients with MS compared to those without MS. Conclusion: About 40% patients with CLBA have metabolic syndrome, and they have more severe pain and disability.
