Objectives: The purpose of this study is to investigate the difference in prevalence of snoring between aging male and emale, and to explore a risk factor affecting snoring in female.
Methods: A total of 4170 subjects (male:2277(54.6%), female: 1893(45.40%)) enrolled in ANSAN Health Study were andomly recruited and questions related snoring including demographic information and sleep-related symptoms were taken by well trained surveyors. We calculated the prevalence of snoring in male and female, and compared the difference Af prevalence distribution.
Results: The overall prevalence of snoring was higher in male than that of female (M: 39.91%, F: 19.65%). The peak ige in male was 40-50s and in female was 50s, but the prevalence of snoring became almost same level with the progress of ige after 50s. And the prevalence in postmenopausal group is same as that in more than 50s group (29.67%, 30.40%).
Conclusion: This study shows two interesting results; (1) The snoring increased significantly after menopause. (2) After menopause, the prevalence of snoring becomes almost same in both male and female. This data provide that postmenopausal hormonal change may influence the mechanism of snoring leading to increase the prevalence of snoring in menopausal women. The further patho-physiologic evaluation may be needed in women.
