COSTANZO, P. et al. Erectile dysfunction is associated with a high prevalence of obesity and metabolic syndrome. Rev. argent. endocrinol. metab. [online]. 2008, vol.45, n.4, pp.142-148. ISSN 1851-3034.

Introduction: The erectile dysfunction (ED) is associated with metabolic and endocrine diseases and with high frequency to Type 2 Diabetes Mellitus (DM2), even with good glycemic control. Besides ED is associated with others metabolic syndrome (MS) components like hypertension (HT), obesity and dyslipidemia (DLP), without hyperglycemia. These observations has guided us to consider the hypothesis that ED could be installed early in patients with the MS and previously to DM2 diagnosis. Aims: To evaluate in a ED patients group: 1) metabolic and cardiovascular risk factors and MS prevalence; 2) impaired glucose tolerance prevalence. Methods: We included 77 patients with ED (group P). Control group: 17 men without ED (group C). Exclusion criteria: pharmacologic, anatomic or endocrine ED (hypogonadism or hyperprolactinemia), DM2, prior prostatic surgery or chronic illnesses. The erectile function was rated according the International Index of Erectile Function 5. Multiple metabolic and cardiovascular risk factors were evaluated: HT, DLP, obesity, smoking and sedentarism lifestyle. The MS was evaluated according the International Diabetes Federation (IDF) and National Cholesterol Education Program-Third Adult Treatment Panel (NCEP-ATPIII) criteria. Results: The prevalence of HT and DLP was higher in group P vs group C: 82.2 % vs 23.5 % (p=0.03) and 68.5 % vs 23.5 % (p=0.04), respectively. Twenty new cases of HT and 24 new cases of DLP were detected. Group P patients had a higher waist circumference and body mass index than group C ones: 105.3 ± 9.7 vs 98.1 ± 7.5 cm (p=0.004) and 29.8 ± 4.3 vs 26.2 ± 2.9 kg/m² (p=0.0003), respectively. The prevalence of MSIDF and MS-NCEP-ATPIII was higher in group P vs group C: 68.5 % vs 23.5 % (p=0.04) and 52.1 % vs 11.8 % (p=0.02), respectively. No differences were found in impaired glucose tolerance prevalence. Conclusion: Men with ED have a high prevalence of HT, DLP, obesity and MS. Early detection of these factors in patients with ED provides an unique opportunity for DM2 and cardiovascular disease prevention.
