Task: Intent Identification
Input (English): To compare the circulating concentrations of the acute-phase protein serum amyloid A (SAA) in lean, overweight, and obese children and adolescents and analyze the influence of body fat.', 'A total of 63 children and adolescents (65% girls) with an average age of 12.1 +/- 2.7 years (range, 6 to 18 years) were included in the study. Each child was classified on the basis of age- and sex-specific body mass index (BMI) percentile as normal weight (BMI <85th percentile; n = 17), overweight (BMI >/=85th and <95th percentiles; n = 26), or obese (BMI >/=95th percentile; n = 20). Body fat was estimated by air-displacement plethysmography.', 'Both overweight and obese children exhibited significantly increased circulating SAA concentrations (log SAA: lean, 0.66 +/- 0.20; overweight, 0.83 +/- 0.29; obese, 0.96 +/- 0.21; P = .002) compared with the lean children. Significant correlations were found between log SAA and body fat (r = 0.48; P < .0001). In multiple linear regression analysis, log C-reactive protein (CRP) (P = .014) and body fat (P = .031) emerged as significant predictors of log SAA.
