Digital photos of the lateral borders of the tongue, height, weight, waist, hip and blood pressure were registered, and blood samples were analyzed. Those with SV were compared with those without SV (nSV).Results: Those with SV had more hypertension 41.8% vs 27.0% (p< 0.0001), a higher systolic blood pressure (BP) 139.5 (SD 18.6) mmHg vs 134.3 (SD 18.8) mmHg (95% CI − 7.73 &boxh; − 2.72), more diabetes type 2 (DM-2) 7.4% vs 3.8% (p=0.014), a higher fasting plasma glucose 5.9 (SD 1.5) mmol/L vs 5.7 (SD 1.0) mmol/L (95% CI − 0.42 &boxh; − 0.05), more dyslipidemia 24.1% vs 17.7% (p=0.018), lower HDL 1.6 vs 1.7 (p=0.003), a greater waist circumference 97.0 cm vs 93.9 cm (95% CI − 4.66 &boxh; − 1.46), a greater waist/hip ratio 0.92 cm/cm vs 0.90 cm/cm (95% CI − 0.03 &boxh; − 0.01), and a higher BMI 26.6 kg/m2 vs 26.0 kg/m2 (95% CI − 1.11 &boxh; − 0.03). The following associations with SV were found in multivariate analysis: hypertension OR=1.6 (95% CI 1.19 &boxh;2.13), a high systolic BP OR =1.5 (95% CI 1.11 &boxh;2.13), a high fP-glucose OR= 1.8 (95% CI 1.03 &boxh;3.21), a low HDL OR= 1.8 (95% CI 1.15 &boxh;2.92), a greater waist circumference OR= 1.68 (95% CI 1.10 &boxh;2.58), a greater waist/hip ratio OR=2.21 (95% CI 1.36 &boxh;3.58), and a higher BMI OR=1.05 (95% CI 1.02 &boxh;1.09).Conclusion: This study shows an association between SV and a high BP, a high fP-glucose, hypertension, diabetes mellitus type 2, dyslipidemia, abdominal obesity, older age and smoking.Keywords: sublingual varices, cardiovascular riskfactors
