Hi folks:

The following also seems relevant:

" BACKGROUND: The determinants of change in bone mineral density (BMD)

have been well characterized in women but not in men. This

prospective study describes the patterns of BMD change at the hip and

spine, incidence of osteoporosis, and modifiable predictors of bone

loss in 507 ambulatory community-dwelling men aged 45 to 92

years. ......................

" RESULTS: Annual BMD loss averaged 0.47% at the total hip and 0.34%

at the femoral neck with an annual average of 0.22% gain at the

spine. The rate of BMD loss at the hip and incidence of osteoporosis

increased significantly with age. The main predictors of BMD loss

were age >/=75 years, baseline BMI <24 kg/m(2), 4-year weight loss of

>/=5%, current smoking, and physical inactivity. Moderate alcohol

consumption showed some bone-sparing effect. Diuretic and calcium

supplement use were not associated with bone loss.

" CONCLUSIONS: Relatively healthy community-dwelling men lose bone

with age, and men aged >/=75 years are particularly vulnerable.

Potentially modifiable characteristics such as low body mass, weight

loss, smoking, and physical inactivity were important predictors of

bone loss and should be considered for the prevention of osteoporosis

in men.

Hi All,

PS from the available pdf:

Statistical analysis

The SPSS program (version 10.0) for Windows (SPSS,

Chicago, IL, USA) was used for statistical analyses.

Values for results are given as means±SD. Correlation

analyses were performed using the Pearson correlation

test. Comparison of mean values between groups,

according to the BMD and IGF-I quartiles, were per-formed

using analysis of variance (ANOVA) test and

post-hoc analysis. For categorical data, the chi^2 test was

used for difference of distribution between groups.

Multiple regression analyses were used to quantify the

predictors of lumbar spine and femoral neck BMD.

Variables which showed significance on univariatle

analysis were included as independent variables in the

regression model, and the final regression model was

selected by stepwise selection. Variables with a signifi-

cance value of less than 0.05 were included, and vari-ables

with a significance value of more than 0.1 were

excluded in the final model.

Hi Ceil!

Thanks for sharing your information with us. I'm very curious if

there will be any change in you since starting Gleevec.

Many Thanks,

Lynn
