Table 1 Anthropometric measures and body composition evaluated by BIA parameters of the psoriatic patients and control group

From: Nutrition and psoriasis: is there any association between the severity of the disease and adherence to the Mediterranean diet?

  1. Psoriatic patients exhibited statistically significant differences compared with control group sex, age and BMI-matched for BIA parameters. In particular psoriatic patients have the lowest values of Na/K ratio, FFM (%), SMM (%),TBW (%) and higher values of FM (Kg) and FM (%). Differences between the two groups were analyzed by paired t test. BW, Body weight; BMI, Body Mass Index; R, Resistance (Ω = ohm); Xc, Reactance (Ω = ohm); PA, Phase Angle (° = degrees); R/H, Resistance standardized by Height (Ω/m = ohm/meters); Xc/H, Reactance standardized by Height (Ω/m = ohm/meters); Na/K, Sodium/Potassium; BCMI, Body Cell Mass Index; FM, Fat Mass; FFM, Fat-Free Mass; BCM, Body Cell Mass; SMM Skeletal Muscle Mass; TBW, Total Body Water; ECW, Extra-Cellular Water; ICW, Intra-Cellular Water.
