A survey using Gammadensit x-ray bone mineralometer was conducted on 1
50 Saudi Arabian postmenopausal (PM) females and on another group of 1
50 females of menstruating age of around 30 years as the group with pe
ak bone mass (PBM). The minimum age in the PM group was 44 years and m
aximum was 71 years (mean 54.08 years), SD +/- 7.02, whereas for the P
BM group, the mean age was 29.15 years (range 24 to 33). The bone mine
ral density (BMD) for the PM group was 0.310 g/cm(2) minimum and the m
aximum was 0.546 g/cm(2) (mean 0.440 g/cm(2)). In the PBM group, the m
ean BMD was 0.660 g/cm(2). Compared to Western females, the PM group B
MD was 21% lower and the Saudi PBM group was 29% higher than in Wester
n females of the same age and ses. The BMD or rural Saudi females was
0.479 g/cm(2) as compared to 0.359 g/cm(2) in the urban population. In
females who had borne more than 10 children, the BMD was 0.483 g/cm(2
), and was 0.354 g/cm(2) in females who had fewer than five children.
There was no statistical significance in rural versus urban and less t
han or equal to 5 versus greater than or equal to 10 children (P value
was < 0.18 and < 0.13). This study concludes that BMD of the PM Saudi
females is lower than that of the Western females of the same age, ma
king them more osteoporotic with a higher risk of osteoporotic-related
fractures.
