ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between abdominal fat volume and obstructive sleep apnea hypopnea syndrome in obesity people.</p><p><b>METHODS</b>From July 2009 to July 2010, 50 patients with BMI > 25 were prospectively selected for study from the patients who complained of snoring in the Respiratory department. The patients were divided into OSAHS group and non-OSAHS group according to the result of sleep apnea monitoring. All the patients also received full abdominal CT and the whole abdominal fat volume was measured by 3-D CT reconstruction system. SPSS 13.0 was used for statistical analysis.</p><p><b>RESULTS</b>The whole abdominal fat volume in the two groups was analyzed by T- test, which was significantly different between the two groups (P < 0.01). It showed that there was a statistical relationship between OSAHS and abdominal fat in obesity people.</p><p><b>CONCLUSION</b>In obesity people, OSAHS has a close relationship with abdominal fat volume. The abdominal fat volume is markedly higher in OSAHS patients than that in non-OSAHS people.</p>
