Thus, we wished to determine the prevalence of osteoporosis in our peritoneal dialysis (PD) cohort. Lumbar spine (LS) and femoral neck (FN) bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA), and low BMD (osteoporosis) and reduced BMD (osteopenia) defined according to the World Health Organisation\n                    <jats:italic toggle=\"yes\">T<\/jats:italic>\n                    scores.

Fewer patients had normal BMD at the FN vs. LS (24.1 vs. 55%), and more classified as reduced (FN 55.9 vs. 34% LS) and low BMD (FN 17 vs. 11% LS),\n                    <jats:italic toggle=\"yes\">\u03c7<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    112.2,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.001.
