Lumbar Disc Herniation (LDH) is one of the main causes of low back pain. This study aimed to investigate the risk factors for LDH.

... ls were obtained using individuals' medical records. People were interviewed for the job and other information. Based on LDH recurrence, individuals were divided into two groups with/without recurrence. SPSS Ver.17 software and appropriate statistical tests were used to analyze the data. Results: The incidence of LDH recurrence was 28 (9.3%) in the samples. In this study, the number of male samples was 154 (51.2%) with a recurrence of 9.7% and 147 female samples (48.8%) with recurrence of 8.8%, and the mean age of the samples was 48.62 (13.35), with a range of Changes 15-79 years. Based on the results of statistical tests, there was no statistically significant relationship between risk factors and recurrence of LDH. Conclusion: Factors such as gender, age, smoking, physical characteristics, and occupational conditions cause or accelerate the recurrence of LDH in patients. The low volume of the group with LDH recurrence in this study caused no significant relationship between recurrence and risk factors.
