[Dependence of severity of obstructive sleep apnoea syndrome on body mass gain in patients after emergence of snoring symptom].
OBJECTIVE
To search for simple clinical criteria for prediction of obstructive sleep apnoea syndrome (OSAS).


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.


CONCLUSIONS
Body mass gain after onset of snoring can help in prediction of OSAS severity.
