[Retrospective analysis of the studies on sleep apnea-hypopnea syndrome in the past twenty years in our country].
OBJECTIVE
To summarize and evaluate the studies on sleep apnea-hypopnea syndrome (SAHA) in our country.


METHODS
Articles on the study of SAHS published in major journals of our country from January, 1982 to June, 2002 were evaluated retrospectively.


RESULTS
262 articles were recruited. More papers covering more aspects of this disorder were getting published in the past 20 years. However, basic studies, multidisciplinary studies, more effective therapies and large size, multicenter, and prospective trials were lacking. The study of SAHS in different provinces did not reach the same level.


CONCLUSIONS
Large sampled, multicenter and multidisciplinary prospective trials are needed to study more effective and acceptable therapies as well as the basic mechanism of SAHS.
