Bone Density

[Guest guest]

Hi folks:

I found this to be unusually relevant for males, perhaps not only for

koreans:

" Osteoporosis is a growing health problem in women and in men. This

cross-sectional study examined the association of anthropometric,

lifestyle, and hormonal factors with bone mineral density (BMD) in

152 healthy Korean middle-aged men. ....................

" Of the middle-aged men, 3.9% were osteoporotic and 28.3% were

osteopenic at the lumbar spine site, and 5.9% were osteoporotic and

45.4% were osteopenic at the femoral neck site.

" Lumbar spine BMD correlated significantly with body mass index

(BMI), and femoral neck BMD correlated significantly with age, BMI,

and serum IGF-I levels. The lowest quartile group for serum IGF-I

levels showed the lowest femoral neck BMD.

" Osteoporotic men by lumbar spine BMD showed significant differences

from the normal BMD group in terms of BMI and smoking habits. Also,

osteoporotic men by femoral neck BMD were significantly different for

mean age, BMI, and serum IGF-I levels compared with the normal BMD

group.

" On multiple regression analysis, BMI was found to be the only

independent predictor of lumbar spine BMD, whereas both BMI and serum

IGF-I levels were found to be the independent predictors of femoral

neck BMD. ....................

" We suggest that higher age, a lower BMI, current smoking history,

and lower serum IGF-I levels are risk factors for lower BMD in middle-

aged Korean men; however, serum testosterone levels and GH secretory

capacity were not found to be correlated with BMD.

Note especially the: " BMI was found to be the only independent

predictor of lumbar spine BMD " .
