Adiponectin in patients with obstructive sleep apnea syndrome / 中国医师杂志

ABSTRACT

Objective To investigate the changes of serum adiponectin level and insulin resistance in patients with obstructive sleep apnea hypopnea syndrome (OSAHS).Methods 80 adult habitual snorers were divided into mild,moderate,severe OSAHS groups and control group,based on their apnea hypopnea index (AHI).Correlative clinical data were measured and analyzed.Results Serum adiponectin level [( 5.44 ± 2.57 ) mg/L] was significantly lower and HOMA-insulin resistance index ( 3.42 ± 0.70) was significantly higher in severe group than other groups ( P ＜ 0.05 ).Serum adiponectin level was negatively correlated with BMI,waist hip ratio,neck circumferences and et al( r =-0.233 ～ -0.499,P ＜0.05),but it was positively correlated with lowest oxygen saturation ( LSaO2 ),Ⅲ + Ⅳ％ and REM％ ( r =0.270～ 0.429,P ＜ 0.05).Conclusions Both hypoadiponectinemia and insulin resistance were observed in severe OSAHS patients.The related risk factors of hypoadiponectinemia in OSAHS might include obesity,disordered sleep architecture and other adipokines.
