Abstract

Aims

To identify metabolic phenotypes at increased risk of impaired glucose tolerance (IGT) in Italian overweight/obese children (n = 148, age 5–10 years) and adolescents (n = 531, age 10–17.9 year).

Methods

Phenotypes were defined as follows: obesity by the 95th cut-points of the Center for Disease Control body mass index reference standards, impaired fasting glucose (fasting plasma glucose ≥100 mg/dl), high circulating triglycerides (TG), TG/HDL cholesterol ≥2.2, waist-to-height ratio (WTHR) >0.6, and combination of the latter with high TG or TG/HDL cholesterol ≥2.2.

Results

In the 148 obese children, TG/HDL-C ≥ 2.2 (OR 20.19; 95 % CI 2.50–163.28, p = 0.005) and the combination of TG/HDL-C ≥ 2.2 and WTHR > 0.60 (OR 14.97; 95 % CI 2.18–102.76, p = 0.006) were significantly associated with IGT. In the 531 adolescents, TG/HDL-C ≥ 2.2 (OR 1.991; 95 % CI 1.243–3.191, p = 0.004) and the combination with WTHR > 0.60 (OR 2.24; 95 % CI 1.29–3.87, p = 0.004) were associated with significantly increased risk of IGT. In the whole sample, having high TG levels according to the NIH National Heart, Lung and Blood Institute Expert Panel was not associated with an increased risk of presenting IGT.

Conclusions

TG/HDL-C ratio can be useful, particularly in children, to identify obese young patients at risk of IGT. Its accuracy as screening tool in a general population needs to be verified. The combination of TG/HDL-C ratio and WTHR > 0.6 did not improve prediction. Having high TG according to the NIH definition was not associated with increased risk of developing IGT.
