PURPOSE
The aims of this cross-sectional study were to determine the prevalence of Staphylococcus aureus nasal colonization, evaluate community-related behavioral risk factors, and utilize staphylococcal protein A (spa) typing for epidemiological surveillance among community-based men who have sex with men from the National HIV Behavioral Surveillance System in Houston, Texas.
METHODS
Descriptive methods and logistic analyses were used to determine associations with nasal colonization.
RESULTS
The prevalence of S. aureus colonization was 29.7%; of these, 3.0% were colonized with methicillin-resistant S. aureus. Logistic analyses revealed that anal intercourse practices were associated with colonization (P < 0.05). A diverse population of 38 spa types was identified.
CONCLUSION
Our findings suggest that an association among preferential sex practices, condom use, and S. aureus colonization exists and should be investigated further.
目的
本横断面研究旨在确定金黄色葡萄球菌鼻腔定植的流行率，评估与社区相关的行为危险因素，并利用葡萄球菌蛋白 A（spa）分型对来自德克萨斯州休斯顿的全国艾滋病毒行为监测系统的社区男男性行为者进行流行病学监测。
方法
采用描述性方法和逻辑分析来确定与鼻腔定植相关的因素。
结果
金黄色葡萄球菌定植的流行率为 29.7%；其中 3.0%定植有耐甲氧西林金黄色葡萄球菌。逻辑分析显示，肛交行为与定植有关（P<0.05）。鉴定出 38 种 spa 型的多样化人群。
结论
我们的研究结果表明，偏好的性行为、使用避孕套与金黄色葡萄球菌定植之间存在关联，这一关联值得进一步研究。
