Evaluation of Smoking, Diabetes Mellitus and Obesity associations with Degenerative Lumbar Spinal Stenosis in Elderly

Background: Degenerative lumbar spinal stenosis (LSS) is a common condition affecting mainly old age group with high incidence and prevalence, and is associated with many factors. Aim: Our study aimed to evaluate smoking, diabetes mellitus and obesity associations with degenerative LSS. Patients and methods: A comparative crosssectional study with participants 60 years of age or older. Participants suffered from degenerative LSS were enrolled as the diseased group after diagnosis with MRI, healthy persons (age and gender matched) were considered as control group. Smoking, diabetes mellitus and obesity variables were collected and analyzed using chi-square and odds ratio. Results: Around 162 participants enrolled the study, 62 were considered as degenerative LSS group, whereas 100 were considered as the control group. In LSS group, a picture obtained was of 20:42 smokers to non-smoker, 22:20 diabetic to non-diabetic, 37:25 obese to non-obese. While in the controlled group a picture was obtained with 18:82 smokers to non-smoker, 18-82 diabetic to non-diabetic, 34:66 obese to non-obese. Chi-square p-value was of 0.037, 0.012 and 0.001 for smoking, diabetes mellitus, and obesity, respectively. The odd ratio was 2.17, 2.5 and 2.87 for smoking, diabetes mellitus, and obesity, respectively. All above results were significant. Conclusion: Each of smoking, diabetes mellitus, and obesity has a great association with the development of degenerative LSS in elderly age group. Obesity shows the highest association among them.
