BACKGROUND: Diabetic retinopathy (DR) is a major microvascular complication of diabetes mellitus and a leading cause of visual impairment. While dyslipidemia has been implicated in DR pathogenesis, the relationship between high-density lipoprotein cholesterol (HDL-C) and DR remains controversial. This study aimed to investigate the association between HDL-C levels and DR prevalence in diabetic patients type 2 diabetes mellitus (T2DM).
METHODS: This study is the second analysis based on a cross-sectional studv. A total of 2001 (858 men and 1143 women) diabetic patients who visited the diabetic clinic in the Internal Medicine out-patient departments of two hospitals in southern Taiwan between April 2002 and November 2004. Demographic and clinical data were collected, and serum HDL-C levels were measured. The association between HDL-C and DR was analyzed using multivariate logistic regression, accounting for potential confounders. Additionally, we explored the potential correlation between HDL-C and DR through a smooth curve fitting approach, utilizing a generalized additive model (GAM). and a generalized additive model (GAM).
RESULTS: Among the 2001 participants, 701 (35.0%) were diagnosed with DR. Our findings demonstrated a significant inverse linear relationship between HDL-C levels and the presence of DR. Higher HDL-C was inversely associated with diabetic retinopathy (DR). In continuous analyses, each 10 mg/dL increase in HDL-C corresponded to lower odds of DR across all models, including Model 3 (OR 0.92; 95% CI 0.84-0.99; P = 0.027).Additionally, analysis of HDL-C levels by tertiles revealed that participants in the highest tertile (53.0-99.0 mg/dL) had a lower prevalence of DR, with an OR of 0.78 (95% CI: 0.62-0.97; P = 0.029) in Model 1; this association was borderline in Model 2 (OR: 0.80; 95% CI: 0.63-1.01; P = 0.055) and non-significant in Model 3 (OR: 0.86; 95% CI: 0.66-1.09; P = 0.209). In categorical analyses (reference: ≤40 mg/dL), participants with HDL-C ≥ 60 mg/dL exhibited a significantly lower prevalence of DR in Model 1 (OR: 0.73; 95% CI: 0.56-0.97; P = 0.028), a borderline association in Model 2 (OR: 0.76; 95% CI: 0.57-1.01; P = 0.059), and a non-significant association in Model 3 (OR: 0.83; 95% CI: 0.61-1.14; P = 0.259).
CONCLUSIONS: This study provides evidence of a linear association that elevated HDL-C levels are associated with decreased odds of DR in diabetic patients. Future research should further focus on elucidating the mechanisms underlying this association and its implications for therapeutic strategies.
