چکیده
OBJECTIVE To investigate whether obstructive sleep apnea/hypopnea syndrome (OSAHS) is independently associated with insulin resistance (IR). METHODS We recruited 60 male obese patients with OSAHS [OSAHS group, age (42.3 +/- 2.6) years, body mass index (BMI) (28.3 +/- 2.1) kg/m2, waist/hip ratio (WHR) 0.95 +/- 0.05], 60 male weight-matched obese patients without OSAHS [OB group, age (41.5 +/- 3.1) years, BMI (27.7 +/- 1.5) kg/m2, WHR 0.94 +/- 0.04] and 60 male normal weight subjects [NW group, age (41.8 +/- 2.4) years, BMI (22.6 +/- 1.9) kg/m2, WHR 0.86 +/- 0.05]. The subjects underwent polysomnography and OSAHS was defined as an apnea-hypopnea index (AHI) > or = 5. The systolic blood pressure and diastolic blood pressure were measured. IR was evaluated by fasting serum true insulin (TI) level and IR index based on the homeostasis model assessment method (HOMA-IR). In the OSAHS group, multiple linear regression was used with either TI or HOMA-IR as the dependent variable, and the corresponding set of independent variables included age, BMI, WHR, AHI and minimum oxygen saturation (MSpO2). RESULTS After adjustment for age, BMI, and WHR, the OSAHS group was more insulin resistant, as indicated by the higher levels of TI and HOMA-IR. Multiple linear regression showed that the central obesity parameter (WHR) was the major determinant of IR of the OSAHS group, while sleep-disordered breathing parameters (AHI and MSpO2) were also independent determinants of IR of the group (TI: AHI P = 0.017, TI: MSpO2 P = 0.005; HOMA-IR: AHI P = 0.008, HOMA-IR: MSpO2 P = 0.003). CONCLUSION OSAHS may be independently associated with IR.

Abstract Bckground: Patients with obstructive sleep apnea (OSA) are at risk of developing the fatty liver as a result of being overweight. Several studies suggest that OSA per se could be a risk factor for liver injury and ischemic hepatitis with OSA. The OSA is an independent risk factor for Insulin resistance. Therefore, we investigated liver enzymes and insulin resistance in patients with O...

Sleep apnea is clinically recognized as a heterogeneous group of disorders characterized by recurrent apnea and/or hypopnea. Its prevalence ranges from 4% to 24%. It has been implicated as an independent risk factor for several conditions such as hypertension, stroke, arrhythmia, and myocardial infarction. Recently data has been emerging which suggests an independent association of obstructive ...
متن کاملObstructive sleep apnea is independently associated with insulin resistance.
Epidemiological studies have implicated obstructive sleep apnea (OSA) as an independent comorbid factor in cardiovascular and cerebrovascular diseases. It is postulated that recurrent episodes of occlusion of upper airways during sleep result in pathophysiological changes that may predispose to vascular diseases. Insulin resistance is a known risk factor for atherosclerosis, and we postulate th...
