Reduced arterial compliance associated with metabolic syndrome in Chinese children and adolescents.
OBJECTIVE
To explore the metabolic syndrome and its association with arterial compliance in Chinese children and adolescents.


METHODS
337 participants aged 6 to 18 years with males accounted for 55.8% were grouped according to their traits of metablic syndrome. Anthropometry, blood pressure, fasting plasma glucose, insulin and serum lipid profile were measured. Homeostasis model was assessed and insulin resistance (HOMA-IR) index was measured and calculated for estimating individual insulin resistance. Arterial compliance was also measured using digital pulse wave analyzing method (Micro medical, London), and stiffness index was calculated.


RESULTS
The stiffness index in participants with metablic syndrome was significant higher than that in participants with no riskof metablic syndrome [(7.69 +/- 1.63) vs (6.25 +/- 0.86) m/s, P < 0.01] and stiffness index and HOMA-IR were progressively increased with the increase of traits of metablic syndrom (P for linear trend < 0.001). After gender, age, and pubertal development were adjusted, both traits of metablic syndrome and HOMA-IR were correlated positively with stiffness index (both P < 0.05).


CONCLUSIONS
The clustering of metablic syndrome was closely associated with risk at increased arterial stiffness in Chinese children and adolescents. It was suggested that arterial compliance assessment of children and adolescents might be an important measure for prevention of cardiovascular diseases.
