Abstract
The aim of this study was to assess the association between a new metabolic index, the cardiometabolic index (CMI) and erectile dysfunction (ED). The data for this study relied on the National Health and Nutrition Examination Survey (NHANES), a cross-sectional database, between 2001 and 2004. The CMI was calculated as the following formula: Triglyceride (TG) (mmol/L)/ High density lipid-cholesterol (HDL-C) (mmol/L) ×waist-height ratio (WHtR). The multivariate logistic regression analyses were conducted to assess the association between CMI and ED, supplemented by subgroup analysis and dose-response curves. Finally, a total of 1367 adult male participants were identified, and the mean CMI was 0.83 ± 0.02. Multivariate logistic regression analysis showed that in model 2 controlling for all potential confounders, CMI was significantly associated with ED (OR = 1.49, 95% CI: 1.09, 2.04) (p = 0.017). Subsequently, we convert the CMI from a continuous variable to a categorical variable (Tertiles). The results showed that male participants in CMI Tertile 3 group had a higher risk of ED than those in Tertile 1 group in model 2 (OR = 2.07, 95% CI: 1.12, 3.83, P = 0.024). The subgroup analysis of model 2 demonstrated that CMI was significantly associate with ED in participants aged ≥50 y (OR = 2.31, 95% CI: 1.35, 3.95, P = 0.005), body mass index (BMI) > 30 kg/m2 (OR = 1.78, 95% CI: 1.10, 2.90, P = 0.023), with hypertension (OR = 1.89, 95% CI: 1.63, 3.45, P = 0.020), with diabetes mellitus (OR = 1.67, 95% CI: 1.13, 2.47, P = 0.015), with cardiovascular disease (CVD) (OR = 1.54, 95% CI: 1.12, 2.10, P = 0.011) and smoking (OR = 2.07, 95% CI: 1.26, 3.39, P = 0.007). This study demonstrates a strong association between CMI and ED and an increased risk of ED with higher CMI levels. More prospective studies with large samples and good designs are needed to validate our results in the future.
