There is a growing body of evidence in the literature correlating erectile dysfunction to obesity. We investigated the correlation of different anthropometric indexes of central obesity to erectile dysfunction.
A cross-sectional study was performed including 256 consecutive men 40 years old or older. All men completed the International Index of Erectile Function, and were evaluated routinely with a clinical history, physical examination and blood analysis for fasting serum glucose, lipid profile and serum testosterone. Anthropometric measures included body mass index, waist circumference, sagittal abdominal diameter, maximal abdominal circumference, and waist-hip, waist-thigh, waist-height, sagittal abdominal diameter-thigh and sagittal abdominal diameter-height indexes.
In men 40 to 60 years old the different anthropometric indexes of central obesity were not correlated with the presence of erectile dysfunction (p > 0.05). Men older than 60 years (41%, range 61 to 81) demonstrated an association among erectile dysfunction and waist-hip index (p = 0.04), waist-thigh index (p = 0.02), sagittal abdominal diameter (p = 0.03), sagittal abdominal diameter-height index (p = 0.02) and maximal abdominal circumference (p = 0.04). After logistic regression analysis an independent effect on the presence of erectile dysfunction was observed for waist-hip index (OR 8.56, 95% CI 1.44-50.73), sagittal abdominal diameter (OR 7.87, 95% CI 1.24-49.75), sagittal abdominal diameter-height index (OR 14.21, 95% CI 1.11-182.32), maximum abdominal circumference (OR 11.72, 95% CI 1.73-79.18) and waist circumference (OR 19.37, 95% CI 1.15-326.55).
This study suggests that central obesity, assessed by several anthropometric indicators, is associated to the presence of erectile dysfunction in men older than 60 years. Sagittal abdominal diameter, sagittal abdominal diameter-height index, maximum abdominal circumference, waist circumference and waist-hip index were useful indicators to predict the presence of erectile dysfunction.
文献中越来越多的证据表明勃起功能障碍与肥胖相关。我们研究了中心性肥胖的不同人体测量指标与勃起功能障碍之间的相关性。
进行了一项横断面研究，纳入了256名连续的40岁及以上男性。所有男性均完成了国际勃起功能指数，并通过临床病史、体格检查以及空腹血糖、血脂谱和血清睾酮的血液分析进行常规评估。人体测量指标包括体重指数、腰围、腹矢状径、最大腹围以及腰臀比、腰大腿比、腰身高比、腹矢状径大腿比和腹矢状径身高比。
在40至60岁的男性中，中心性肥胖的不同人体测量指标与勃起功能障碍的存在无关（p>0.05）。60岁以上的男性（41%，范围61至81岁）显示勃起功能障碍与腰臀比（p = 0.04）、腰大腿比（p = 0.02）、腹矢状径（p = 0.03）、腹矢状径身高比（p = 0.02）和最大腹围（p = 0.04）之间存在关联。经过逻辑回归分析，发现腰臀比（OR 8.56，95% CI 1.44 - 50.73）、腹矢状径（OR 7.87，95% CI 1.24 - 49.75）、腹矢状径身高比（OR 14.21，95% CI 1.11 - 182.32）、最大腹围（OR 11.72，95% CI 1.73 - 79.18）和腰围（OR 19.37，95% CI 1.15 - 326.55）对勃起功能障碍的存在有独立影响。
本研究表明，通过多种人体测量指标评估的中心性肥胖与60岁以上男性勃起功能障碍的存在相关。腹矢状径、腹矢状径身高比、最大腹围、腰围和腰臀比是预测勃起功能障碍存在的有用指标。
