This study aimed to define the levels of vitamin D3 in postmenopausal women and
their relation with bone mineral density (BMD). The study included 83 women (48-81 year)
who visited the Department of radiology of Al Asad hospital in Lattakia. Bone m
ineral density of
the lumbar spine (L1–L4) and total hip was measured by dual-energy X-ray absorptiometry (DXA).
Blood samples were collected to assay 25(OH)D3 and Ca.
The mean level of 25(OH)D3 was 18.87 ng/ml (6.96 SD) and the prevalence of
vitamin D3 difficiency { 25(OH)D3<20 ng/ml} was 64%. No correlation was found
between BMD and 25(OH)D3 levels [P value>0.05], and no correlation was found between
25(OH)D3 and age or body mass index (IMD). We found a strong correlation between
25(OH)D3 and duration of sun exposure (P value = 0.01). Conclusion: Hypovitaminosis D3
is very common among postmenopausal women. Vitamin D33 status may not be an
important determinant of bone health.
