Phase angle and Mediterranean diet in patients with acne: Two easy tools for assessing the clinical severity of disease

Table 3 Age, anthropometric characteristics, and body composition characteristics were assessed by bioelectrical impedance analysis in patients with acne, across GAGS categories

Parameters	Mild acne n = 17	Moderate acne n = 26	Severe acne n = 8	*p-value
Age (years)	24.1 ± 4.5	23.5 ± 6.2	22.3 ± 7.8	0.780
Weight (kg)	62.4 ± 5.9	68.6 ± 15.4	80.9 ± 22.8	0.017
BMI (kg/m²)	22.8 ± 1.5	24.8 ± 3.7	28.8 ± 5.9	0.002
Waist circumference (cm)	74.8 ± 4.9	79.6 ± 11.0	86.5 ± 11.3	0.020
R (Ω)	526.9 ± 73.6	548.3 ± 75.2	536.6 ± 102.6	0.684
Xc (Ω)	57.5 ± 8.5	56.2 ± 6.3	51.0 ± 11.1	0.163
PhA (°)	6.3 ± 0.6	5.9 ± 0.5	5.4 ± 0.6	0.006
TBW (Lt)	35.9 ± 3.9	36.2 ± 5.4	38.9 ± 6.9	0.386
ICW (Lt)	19.9 ± 2.6	19.5 ± 2.9	19.9 ± 3.0	0.867
ECW (Lt)	16.1 ± 1.8	16.8 ± 2.8	19.0 ± 4.1	0.050
ECW/ICW ratio	0.81 ± 0.08	0.86 ± 0.09	0.95 ± 0.11	0.007
FM (Kg)	13.2 ± 5.2	18.9 ± 10.6	22.8 ± 19.9	0.015
FFM (Kg)	49.1 ± 5.4	49.6 ± 7.3	53.1 ± 9.4	0.392
BCM (Kg)	26.6 ± 4.8	24.6 ± 5.2	23.3 ± 5.9	0.261

Stratifying patients with acne according to GAGS categories, weight, BMI, waist circumference, ECW, ECW/ICW ratio, and FM increased, while PhA decreased significantly. Results are expressed as mean ± SD. Weight and ECW were logarithmically normalized and transformed and back-transformed for presentation in table. Differences in the three groups were analysed by ANOVA test, with the Bonferroni test as post-hoc test. *A p value in bold type denotes a significant difference (p < 0.05)
