Multivariate linear regression analysis of factors independently associated with bone mineral density of the hip or spine among HIV-infected men.

Characteristic Femoral neck (β-coefficient)a P-value Lumbar spine (β-coefficient)a P-value
Age (per year) −0.0001 NS 0.006 0.03
Non-black race −0.018 0.004 −0.06 0.02
Weight (per kg)b 0.003 < 0.0001 0.003 0.002
Low testosterone −0.02 NS −0.075 0.002
HIV infection > 10 years −0.004 NS −0.075 0.003
Duration of antiretroviral use (months) −0.0004 NS 0.0001 NS
Duration of protease inhibitor use (months) 0.0006 NS 0.0003 NS
CD4 cell count < 200 cells/μl 0.003 NS −0.03 NS
a

β-coefficients less than zero indicate an inverse association between the characteristic and bone mineral density.

b

Substitution of body mass index (kg/m2) for weight (kg) did not significantly alter the results of either model, nor alter the β-coefficients or P-values of the other variables in either model.
