The relationship between erectile dysfunction and osteoporosis: a
population-based study in Southern China
Abstract
Aim: To investigate the association of erectile dysfunction (ED) and
osteoporosis in all-aged (18-87 years) males, and by comparing models
with or without ED, explore the ability of ED to assess the prevalence
of osteoporosis. Methods: We performed a cross-sectional study in
Southern China based on the community population from March to July 2015
and 998 eligible individuals ages form 18 to 87 years were included. The
diagnosis of ED was based on self-reporting and osteoporosis was defined
as a bone mineral density (BMD) of 2.5 standard deviations or below (T
score ≤−2.5). Odds ratios (OR) and 95% confidence intervals (95%CI)
were calculated in logistic regression model. Lasso regression model was
used for feature selection. Receiver operating characteristics (ROC)
curve analysis was used to evaluate the ability of the different models
to assess the prevalence of osteoporosis. Results: The prevalence of
osteoporosis was 1.70-fold higher in the ED group compared with the
non-ED group (OR: 1.70, 95%CI: 0.99-2.87, P=0.051) after adjustment in
total population. AUC in model with biochemical indices including low
density lipoprotein cholesterol (LDL-C) and fasting plasma glucose
(FPG), further plus ED was 0.73 (95% CI: 0.68-0.79), which was
significantly higher than model only with non-invasive basic clinical
parameters (AUC: 0.70, 95% CI: 0.65-0.80). Model included only
biochemical indices evaluated the AUC from 0.70 to 0.72 (P=0.050), and
further plus ED can significantly evaluated the ability of diagnosis
osteoporosis (P=0.017). Conclusions: We found that patients with ED had
an increased risk of osteoporosis among the all-age (18-87 years) male
population, and the diagnosis ability for osteoporosis significantly
evaluated when plus ED. For assessing osteoporosis in male population,
the information about ED should be collected.
