Abstract
Background:To assess and compare the ability of body fat percentage (BF%) estimated by 2 methods, bioelectrical impedance analysis (BIA) and by the Slaughter et al equations for triceps and subscapular skinfold thickness (SKF), in identifying unfavorable levels of several biomarkers of cardiometabolic risk.Methods:Cross-sectional school-based study with 529 apparently healthy adolescents (267 girls), aged 14.3 ± 1.7 years.Results:BF% estimated by both methods always showed higher areas under the curve (AUC) for each biomarker in girls than in boys (with the exception of BIA for leptin). BF% estimated by BIA and by SKF presented a discriminatory ability in identifying unfavorable levels in all biomarkers of cardiometabolic risk in girls; however, BF% estimated by BIA displayed the highest AUC (except for C-reactive protein). In boys, BF% estimated by SKF presented higher AUC for C-reactive protein, fibrinogen and erythrocyte sedimentation rate; and BF% estimated by BIA for complement C3 and leptin. Positive and significant associations between BIA and SKF with all biomarkers (P < .05) were found (except for SKF and complement C4 in girls, and SKF and fibrinogen and erythrocyte sedimentation rate in boys), after adjustments for pubertal stage, cardiorespiratory fitness, adherence to the Mediterranean diet and socioeconomic status.Conclusions:Overall, diagnostic performance was more accurate in girls. BF% estimated by BIA presented a slightly better overall discriminatory ability for each biomarker than BF% estimated by SKF in girls, while in boys no method clearly prevailed over the other.
Highlights
Adipose tissue is not recognized anymore as fat storage but is accepted as an endocrine organ, and an important source of biologically active substances with local and/or systemic action.[1]
The mean values of BF% were significantly higher when assessed by skinfold thickness (SKF) (19.54%) than with bioelectrical impedance analysis (BIA) (15.86%), P
C-reactive protein (CRP) values were higher in boys, whereas fibrinogen, adiponectin, erythrocyte sedimentation rate (ESR), and leptin were higher in girls (P < .05 for all)
Summary
Adipose tissue is not recognized anymore as fat storage but is accepted as an endocrine organ, and an important source of biologically active substances with local and/or systemic action.[1] the ability of the adipose tissue to develop excessively poses a series of molecular and cellular. The early development of excessive adiposity and its circumstances appear thereby to contribute to an increased risk and to the premature onset of a series of cardiometabolic disorders,[7,8] and as such, its close monitoring is important.[9].
