In multivariate‐adjusted analyses reporting prevalence ratios (PRs) and 95% confidence intervals (CIs), the prevalence of MMAS‐defined complete ED was significantly greater in men in the highest quartile of body weight (PR = 1.24, 95% CI = 1.16–1.34), total body fat percentage (PR = 1.25, 95% CI = 1.13–1.40), and trunk fat percentage (PR = 1.24, 95% CI = 1.15–1.38), and was greater in men with a BMI greater than 30.0 kg/m<sup>2</sup> than in those with BMI of 22.0 to 24.9 kg/m<sup>2</sup> (PR = 1.17, 95% CI = 1.05–1.31).
