Changes in BMI and bone mineral density as induced by two different ARV modalities. BMI regularly increased with time, a significant 5% rise was recorded only in the PI group. Following a 21-month ART (M21) an average 3% reduction of lumbar spine BMD was observed. Bone mineral loss was different between treatments: drop in L2-L4 density was 1.5% the NNRTI group and 4% in the PI group.
