Establishing percentiles for phase angle, skeletal muscle mass index, and muscle-to-fat ratio in Brazilian adolescents: a bioelectrical impedance analysis study with 59,000 participants

BackgroundReliable normative references for adolescent body composition are essential for screening and surveillance, yet Brazilian data at national scale remain scarce and heterogeneous across methods and devices.ObjectivesTo generate age- and sex-specific reference curves for phase angle (PhA), sk...
