Corelation of apnea hypoapnea index concerned with body mass index and neck circumference measurements in patients with obstructive sleep apnea syndrome

Abstract

Objectives:Respiratory disorders during sleep is a common public health problem. OSAS consists of the vast majority of this group of disorders. PSG is the golden standart diagnostic tecnique. However PSG is an expensive, time consuming, special team requiring test and the psg laboratory quantity is very restricted. BMI and neck circumference values are important parameters to differantiate the cases who are going to be referred to PSG. In our study the contribution of BMI and neck circumference measurements has been evaluated in the OSAS diagnosis.Methods:The study was performed in 100 patients, age of 22-76, referred to a private health center between 02/2007- 02/2008. All of the patients were diagnosed as OSAS by clinical findings and PSG results. The first 100 patients were selected from this population without sexual differentiation and the findings were evaluated.Results:In our study we found that: correlation of AHI with BMI and neck circumfrence measurements is statistically very significant in all cases (p<0.01). Statistical significance is present in both sexes but especially in male sexes the significance is much higher. When we evaluated the correlation of BMI and neck circumference with AHI separately: neck circumference showed a much higher correlation with AHI than BMI in all of the cases.Conclusion:Depending on our results, in patients with OSAS suspect, the evaluation of BMI and neck circumference has positive contribution on OSAS diagnosis.
