Exploring the Link between Inflammatory Biomarkers and Adipometrics in Healthy Young Adults Aged 20-35 Years

Obesity and aging are associated with an inflammatory state, which represents the common background for a wide range of diseases. This study aims to explore the correlation between hsCRP, IL-1 beta, IL-6, TNF-alpha, IFN-gamma, and white blood cell count (WBC) and adipometrics (arm, waist, and hip circumferences: AC, WC, HC; total body fat mass: TBFM, visceral fat level: VFL, body mass index: BMI; waist/hip ratio: WHR; waist/height ratio: WHtR) in young and healthy adults aged 20-35 years old. The subjects were divided by BMI into the overweight/obesity (OW/OB) group and normal weight (NW) group, and by hsCRP level into Group 1 (<1 mg/L), Group 2 (>= 1-2.99 mg/L), and Group 3 (>= 3 mg/L). The concentration of all inflammatory biomarkers was significantly higher in the OW/OB group compared to the NW group, with the exception of IL-1 beta. Significant positive correlations were found between hsCRP, TNF-alpha, WBC, and all adipometrics; between IL-6 and WHR, WHtR, BMI, TBFM, and VFL; and between IFN-gamma and HC, BMI, and TBFM. IL-1 beta correlates positively with WHR and VFL. In Groups 1-3, all the differences between the adipometrics showed significant differences. Subclinical inflammation persists in association with being overweight and obese in healthy young adults aged 20-35 years old.
