IntroductionThere is growing interest in using exercise to treat. Although many studies have highlighted the relationship between better erectile function and exercise, black men have been underrepresented in the literature.AimsThis study aims to determine whether or not exercise is associated with better erectile as well as sexual function in black men and define a minimum exercise threshold for which better erectile/sexual function is seen in a cross-sectional study.MethodsOur study population consisted of 295 healthy controls from a case-control study assessing risk factors for prostate cancer conducted at the Durham Veterans Affairs Medical Center, which contained a substantial proportion of black men (n = 93; 32%). Exercise and erectile/sexual function were both determined from self-reported questionnaires. Subjects were stratified into four exercise groups: <3 (sedentary), 3–8.9 (mildly active), 9–17.9 (moderately active), and ≥18 (highly active) metabolic equivalents (MET) hours/week. The association between exercise and erectile/sexual function was addressed utilizing multivariable linear regression analyses.Main Outcome MeasuresErectile/sexual function was defined by the validated Expanded Prostate Cancer Index Composite sexual assessment, which was analyzed as a continuous variable (sexual function score). Clinically significant better function was defined as half a standard deviation (SD) (16.5 points).ResultsMedian sexual function score was 53 (SD = 33). Higher exercise was associated with a better sexual function score (P < 0.001). Importantly, there was no interaction between black race and exercise (P-interaction = 0.772), meaning more exercise was linked with better erectile/sexual function regardless of race. Overall, exercise ≥18 MET hours/week predicted better erectile/sexual function (P < 0.001) with a clinically significant 17.3-point higher function. Exercise at lower levels was not statistically (P > 0.147) or clinically (≤8.14 points higher function) associated with erectile/sexual function.ConclusionsIn a racially diverse population, exercise ≥18 MET hours/week is highly associated with better erectile/sexual function regardless of race.

Abstract

Background

Comorbidities are commonly seen in patients with coronavirus disease 2019 (COVID-19), but the clinical implication is not yet well-delineated. We aim to characterize the prevalence and clinical implications of comorbidities in patients with COVID-19.  相似文献

A technique using two measurements from opposing directions for the assay of the activity of radioactive waste drums, mainly consisting of organic materials, has been studied. A model for the calculation of systematic errors is given by simulating the measurement system. The calculated values are in good agreement with the experimental values. This confirms the validity of the model and proofs the good performance of this technique in practice. These results may provide guidelines for setting up a measuring system for the assay the radwaste drums.  相似文献
