3.1 Basic characteristics of subjects based on status of
osteoporosis
Out of the 998 participants, a total of 172 cases were reported to have
ED, where the percentage was 16.1%, and the percentage of osteoporosis
was 10.5% (112/998) in this study. The median age of this population
was 44 years (Range: 18~87 years). The distribution of
socio-economic and clinical biochemical characteristics according to the
group with osteoporosis were presented in Table 1 . Compared
with the non-osteoporosis population, the osteoporosis population
presented with a higher SBP, DBP, TC and LDL-C (all P<0.05). The osteoporosis group was closely correlated with a
low percentage of education, but a high percentage of smoking and
alcohol consumption (all P <0.05). Importantly, as
shown in Figure 2 , the bone density in ED was lower than that
in non-ED group (-1.9 vs. -1.2, P <0.001) and the
percentage of osteoporosis in the ED group was higher when compared with
the non-ED group (31.25% vs. 13.77%, P <0.001).
