Abstract
OBJECTIVE: Childhood obesity is increasing worldwide. This, in turn, is associated with chronic disease risk factors including hyperlipidaemia. The aim of the present study was to examine adiponectin, acylation-stimulating protein (ASP) and its precursor, complement C3, in very young obese and nonobese children and the corresponding associations with plasma lipid and lipoproteins. All three adipose tissue secreted factors are involved in fat metabolism, and little is known of the levels in very young children. DESIGN AND METHODS: A total of 124 healthy children from 2 to 6 years old were evaluated for weight, height, plasma lipids and adipokines. Based on percentage ideal body weight (%IBW), 60 children were nonobese and 64 were overweight/obese. RESULTS: ASP and C3 were significantly increased (P = 0.0002 and P < 0.0001, respectively) in obese vs. nonobese, and this pattern held true when separated in three age groups: toddler (2-3 years), preschool (4-5 years) and primary school (6 years). By contrast, adiponectin was significantly decreased (P = 0.04). When separated based on a positive family history of obesity, ASP was increased (P = 0.005). Other than a small (23.4%) increase in plasma triglyceride, all other lipids [cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol and nonesterified fatty acids] were normal. ASP, C3 and adiponectin were strongly correlated with %IBW (r = 0.515, P < 0.0001; r = 0.383, P < 0.0001; r = -0.211, P = 0.03, respectively). CONCLUSIONS: Changes in plasma adipokines are seen in very young obese children in the absence of lipid changes. These changes in ASP, C3 and adiponectin in very young obese children may predispose towards enhanced fat storage (ASP) and decreased fat oxidation (adiponectin) further driving the obesity profile.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
