From: Eating disorders in biological males: clinical presentation and consideration of sex differences in a pediatric sample

  Measure of Central Tendencya, Sample size Range % Out of Range (n; Reference Range)
Heart Rate
 Beats per minute (bpm, supine) 61.6 (SD = 18.5), 68 28 – 108 26.5% (18; <  50 bpm)
 Orthostatic Shift (standing - lying) 16.5 (IQR = 15), 60 -6 – 87 33.3% (20; >  20 bpm)
Blood Pressure
 Systolic blood pressure (supine) 105.4 (SD = 12.8), 68 79 – 140 8.8% (6; <  90 mmHg)
 Orthostatic shift in systolic pressureb -1.54 (SD = 7.5), 63 -18 – 17 0% (0; >  20 mmHg drop)
 Diastolic blood pressure (supine) 60.43 (SD = 8.6), 68 43 – 82 2.9% (2; <  45 mmHg)
 Orthostatic shift in diastolic pressureb -4.89 (SD = 7.4), 63 -24 – 11 22.2% (14; > 10 mmHg drop)
Bone Mineral Density (BMD)    Reference Range:
BMD z-score ≤ -1
 Spine z-score -0.45 (SD = 1.0), 35 -2.4 – 1.9 31.4% (n = 11)
 Hip z-score -0.6 (SD = 1.2), 35 -3.0 – 2.1 34.3% (n = 12)
 Total body z-score -0.29 (SD = 1.2), 35 -3.2 – 2.1 28.6% (n = 10)
  1. aMean (Standard Deviation) is reported for variables that were normally distributed. Median (Interquartile Range) is reported for variables with a non-normal distribution
  2. bValues for orthostatic shift in blood pressure are presented as lying-standing to examine postural drop. Reference range for heart rate and orthostatic shifts in pulse and blood pressure are based on admission criteria recommended by the Society for Adolescent Medicine [35]
