Dependence of severity of obstructive sleep apnoea syndrome on body mass gain in patients after emergence of snoring symptom

摘要

AIM: To search for simple clinical criteria for prediction of obstructive sleep apnoea syndrome (OSAS). MATERIAL AND METHODS: Case histories of 389 patients with uncomplicated snoring and OSAS (321 males and 68 females, mean age 55.2 +/- 10.9 years) were analysed retrospectively. The OSAS diagnosis was made according to polysomnographic evidence using somnological systems Minisimno (Sefam, France) and Compumedix S-series (Compumedix, Australia). Correlations between OSAS severity and some clinical parameters were studied. RESULTS: It was found that gain in body mass after onset of snoring significantly correlates with apnea/hypopnea index and with OSAS severity. If the body mass gain was > 10 kg, there is a 95% probability of the existence of moderate or severe OSAS. If the gain was > 20 kg, severe OSAS is highly probable. CONCLUSION: Body mass gain after onset of snoring can help in prediction of OSAS severity.
