Fat mass index (fat mass\/height\n                    <jats:sup>2<\/jats:sup>\n                    in kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    ) was measured in 16 subjects with spinal muscular atrophy using 5 bioelectrical impedance analysis equations and compared with a reference method, dual-energy x-ray absorptiometry. The machine default equation, validated by Cordain, was the primary analysis. Fat mass index calculated by impedance measures differed by between -2.5 kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    and 1.7 kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    from the reference mean (8.3 \u00b1 5.0 kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    ). The Cordain equation provided the smallest difference (-0.4 \u00b1 2.0 kg\/m\n                    <jats:sup>2<\/jats:sup>\n                    ), with correlation coefficient of 0.92. The Cordain equation showed high sensitivity (85.7%) and specificity (100%) for prediction of \u2018\u2018at risk for overweight\u2019\u2019 (fat mass index &gt; 85th percentile for age and gender). Although insufficiently accurate for use as a research tool, bioelectrical impedance can have application as a well-tolerated, noninvasive, easily used screening tool for excess adiposity in patients with spinal muscular atrophy.\n
