Abundance of Gut Microbiota, Concentration of Short-Chain Fatty Acids, and Inflammatory Markers Associated with Elevated Body Fat, Overweight, and Obesity in Female Adolescents

Table 3

Phyla gut microbiota abundance and SCFA concentration of the three groups of body composition classification in female adolescents (Viçosa, MG, Brazil, 2019).

	Group 1 (G1) ()	Group 2 (G2) ()	Group 3 (G3) ()
Bacteria phyla and SCFA	Median (25–P75)	Median (25–75)	Median (25–75)^a	^†
Firmicutes (%)	4.2 (2.3-8.5)	3.6 (1.9-7.3)	5.5 (2.5-10.5)	0.384
Bacteroidetes (%)	126.6 (94.3-154.7)	113.0 (77.5-136.7)	126.4 (91.9-141.5)	0.329
Proteobacteria (%)	3.2 (1.8-6.74)	2.0 (1.0-6.02)	2.5 (1.0-5.0)	0.23
Acetic acid (μmol/g)	8.0 (7.0-10.0)	1.5 (6.0-9.7)	7.0 (6.5-10.0)	0.954
Propionic acid (μmol/g)	5.0 (5.0-8.0)	5.0 (4.0-9.0)	6.0 (5.0-9.0)	0.395
Butyric acid (μmol/g)	1.1 (0.6-1.9)	0.9 (0.6-1.9)	1.1 (0.6-1.6)	0.875

The abundance of phyla is expressed in percentages. ^†Kruskal-Wallis test; SCFA: short-chain fatty acids; EUT: eutrophic; OW: overweight; OB: obesity; G1: eutrophic and adequate body fat percentage; G2: eutrophic and high body fat percentage; G3: overweight or obesity and high body fat percentage.
