Abstract:
Objective To observe the levels of serum 25‐hydroxy(25OH) vitamin D and bone mineral density(BMD) in appar‐ently healthy middle‐aged and elderly people in Zhongshan area and investigate the correlation between each other .Methods The BMD of 200 participants was measured by ultrasound BMD detector ,the participants were divided into 3 groups according BMD re‐sults .Simultaneously ,their serum 25OH vitamin D levels were measured by ECLIA .Results Among 200 participants ,the preva‐lence of vitamin D severe deficiency ,deficiency ,insufficiency and sufficiency w ere 7 cases (3 .5% ) ,35 cases (17 .5% ) ,102 cases (51 .0% )and 56 cases(28 .0% ) ,respectively .There was no significant difference in the BMD values among subgroups of different vitamin D levels(P>0 .05) .The prevalence of low BMD and osteoporosis were 60 cases(30% ) and 10 cases(5% ) ,the levels of ser‐um 25OH vitamin D in normal BMD ,low BMD and osteoporosis group were (67 .31 ± 18 .28) ,(65 .62 ± 15 .41) and (64 .95 ± 19 .86)nmol/L ,respectively .There was no significant difference in the levels of serum 25OH vitamin D among BMD subgroups (P>0 .05) .Serum 25OH vitamin D levels were not directly correlated with BMD(P>0 .05) .Conclusion Vitamin D deficiency and insufficiency are quite serious problems in apparently healthy adults in Zhongshan area .There is no evidence that the status of ser‐um 25OH vitamin D is correlate with BMD ,for laboratory diagnosis of osteoporosis ,more sensitive laboratory markers are needed .
