Daily flossing prevalence was determined among adults ≥30 years old in the United States, by demographic and risk factors for periodontal disease, including current tobacco use and diabetes.
Data from the 2011-2014 National Health and Nutrition Examination Survey were analyzed for 8,356 adults. Flossing prevalence was estimated. Logistic regression analysis examined the association between daily flossing and demographic and risk factors for periodontal diseases.
Daily flossing among adults was 31.6% (standard error [SE] = 0.8). There were significant differences among the categories of flossing according to age, sex, race/Hispanic origin, poverty status, education, current tobacco use, and diabetes status. In adjusted analyses, current tobacco users (odds ratio [OR]: 0.82; 95% confidence index [CI] 0.68, 0.99) had lower odds of daily flossing than non-tobacco users; there was no significant difference between adults with and without diabetes (OR 0.75; 95% CI 0.52, 1.08).
Approximately one-third of adults in the United States reported that they floss daily. Daily flossing was higher among women, those with higher income, and non-Hispanic Asian and Hispanic adults, but it was lower among current tobacco users.
本研究旨在通过牙周病的人口学和危险因素（包括当前吸烟和糖尿病）来确定美国≥30 岁成年人每日用牙线洁牙的流行情况。
对 2011-2014 年全国健康和营养调查的数据进行了分析，共纳入了 8356 名成年人。估计了用牙线洁牙的流行率。采用 logistic 回归分析，评估了每日用牙线与牙周病的人口学和危险因素之间的相关性。
成年人中每日用牙线洁牙的比例为 31.6%（标准误差[SE]为 0.8）。根据年龄、性别、种族/西班牙裔、贫困状况、教育程度、当前吸烟状况和糖尿病状况，用牙线洁牙的比例存在显著差异。在调整分析中，当前吸烟者（比值比[OR]：0.82；95%置信区间[CI]：0.68，0.99）每日用牙线洁牙的可能性低于非吸烟者；有糖尿病和无糖尿病的成年人之间（OR 0.75；95% CI 0.52，1.08）没有显著差异。
在美国，约有三分之一的成年人表示他们每日用牙线洁牙。女性、收入较高者、非西班牙裔亚裔和西班牙裔成年人每日用牙线洁牙的比例较高，而当前吸烟者每日用牙线洁牙的比例较低。
