1Department of Otolaryngology, Taichung Veterans General Hospital, Taichung, Taiwan, ROC. an1654@seed.net.tw
Background:
Snoring is the cardinal symptom of obstructive sleep apnea syndrome (OSAS). To our knowledge, no epidemiological data of sleep-disordered breathing in Taiwan is reported in the literature. The aim of this study was to determine the prevalence of snoring in the area of Taichuing, Taiwan.
Methods:
Data were collected from a random sample of Taichung area residents listed in the Taichung Resident Telephone Directory. Questions were asked by telephone and the answers were recorded and analyzed.
Results:
Among the 1,252 people who were successfully interviewed, 606 were males and 646 were females. The overall prevalence of snoring was 46.8%, while habitual snorers accounted for 13.8%. The prevalence of snoring among males was higher than females (57% vs. 37%, p < 0.001). In addition, adults aged 40-59 years were more likely to snore (p < 0.001).
Conclusions:
Snoring in the area of Taichung, Taiwan is more prevalent in middle-aged adults, especially men. How to ascertain those who have OSAS economically and efficiently requires further investigation.
