Sagital abdominal diameter, but not waist circumference is strongly associated with glycemia, triacilglycerols and HDL-C levels in overweight adults.

Aim: To correlate the sagittal abdominal diameter (SAD) and waist circumference (WC) with metabolic syndrome-associated abnormalities in adults.
Methods: This cross-sectional study included onehundred twelve adults (M=27, F=85) aging 54.0±11.2 yrs and average body mass index (BMI) of 30.5±9.0 kg/m². The assessment included blood pressure, plasma and anthropometric measurements.
Results: In both men and female, SAD and WC were associated positively with body fat% (r=0.53 vs r=0.55), uric acid (r=0.45 vs r=0.45), us-PCR (r=0.50 vs r=0.44), insulin (r=0.89 vs r=0.75), insulin resistance HOMA-IR (r=0.86 vs r=0.65), LDL-ox (r=0.51 vs r=0.28), GGT (r=0.70 vs r=0.61), and diastolic blood pressure (r=0.35 vs r=0.33), and negatively with insulin sensibility QUICKI (r=-0.89 vs r=-0.82) and total cholesterol/TG ratio (r=-0.40 vs r=-0.22). Glycemia, TG, and HDL-c were associated significantly only with SAD (r=0.31; r = 39, r=-0.43, respectively).
Conclusion: Though the SAD and WC were associated with numerous metabolic abnormalities, only SAD correlated with dyslipidemia (TG and HDL-c) and hyperglycemia (glycemia).
