Diabetes mellitus as a risk factor for more severe lumbar disc degeneration: a retrospective study of a Jordanian population
摘要
Diabetes mellitus (DM) is the most common metabolic disease globally. In recent years, studies suggesting an association between DM and lumbar disc degeneration (LDD) have emerged. Nevertheless, no clear causal relationship between them has been established.
ObjectiveTo investigate the relationship between DM and the severity of LDD.
MethodsWe categorized 164 patients into three groups; Group 1 comprised those without DM (n = 59), Group 2 those with pre-diabetes (preDM) (n = 53), and Group 3 those with DM (n = 52). Our data encompassed gender, age, smoking history, duration of DM, and DM medications. The severity of LDD was assessed using the 5-level Pfirrmann grading system.
ResultsAge was the only independent predictor of LDD severity [OR: 1.110 (1.035 – 1.190), p-value = .003] in the non-diabetic group. In the pre-diabetic group, age [OR: 1.092 (1.017 – 1.172), p-value = .015], fasting blood glucose (FBG) [OR: 1.036 (1.004 – 1.068), p-value = .027], and hemoglobin A1C (A1C) [OR: 26.549 (2.892 – 243.715), p-value = .004] were the main predictive factors. In the diabetic group, an exploratory correlation was observed between the Pfirrmann score and A1C (r = 0.288, p-value = .039); however, multivariate analysis revealed no significant predictors for more severe LDD.
ConclusionsHigher A1C levels were modestly associated with increased LDD severity in diabetic and pre-diabetic patients; however, findings were inconsistent across analyses and should be interpreted as exploratory. Larger, prospective studies are needed to clarify this relationship.
