[OSTEOPOROSIS AND BODY MASS INDEX IN RENAL TRANSPLANT RECIPIENTS].
BACKGROUND
frequently after kidney transplantation there is an increase in weight with a resulting high percent of obesity in these recipients. This combined with a rapid loss of bone mass, a higher prevalence of osteoporosis and fractures is evident than in normal populations.


OBJECTIVE
to explore the relationship between body mass index (BMI) and prevalence of osteoporosis in a population of renal transplant recipients.


METHODS
prospective longitudinal study design. The study was conducted on 306 kidney transplant recipients. The relationship between weigh and body mass index with femoral and lumbar osteopenia and osteoporosis prevalence at the moment of transplant and at 12 months post was explored.


RESULTS
there was a high prevalence of overweight (35.6%) and obese (14.1%) recipients after renal transplant and 1 year after (42.2% and 24.2% respectively). Significant differences were found(p = 0.049) between the weight at the time of transplant and the presence of osteopenia or osteoporosis at the lumbar level one year after, the highest weights were in recipients with osteoporosis. The mean BMI was higher (p = 0.028) in osteoporotic patients (26.59 kg/m2) than in patients with osteopenia (24.23 kg/m2).


CONCLUSIONS
results seem to be consistent with recent studies in the general population showing excessive weight as a possible factor detrimental to the bone health.
