全国585家旅店毛巾和床单pH值现状及影响因素分析

Analysis on pH value and influencing factors for public sharing textiles in 585 hotels in China

目的调查旅店公共用毛巾和床单pH值现状,分析其影响因素。方法采用随机抽样的方法,于2016年对全国585家旅店的3 872件毛巾样品、3 742件床单样品进行pH值检测。结果公共用毛巾和床单p H值偏碱性,其中毛巾样品pH值平均值为8.12,合格率为23.4%(906/3 872);床单样品p H值平均值为8.31,合格率为19.8%(741/3 742)。Logistic回归分析结果显示,外送清洗消毒(OR=1.488,95%CI:1.192～1.857)、旅店星级较低(OR=1.305,95%CI:1.152～1.478)可增加床单p H值不合格的风险;旅店星级较低(OR=1.259,95%CI:1.127～1.406)可增加毛巾p H值不合格的风险。结论我国旅店公共用毛巾和床单p H值偏碱性,外送清洗和旅店星级是影响p H值是否合格的因素,建议加强对旅店公共用毛巾和床单的卫生监督。

Objective To investigate the current status of pH value of public sharing towels and bed sheets in hotels and the influencing factors in China. Methods A total of 3 872 samples of towels and 3 742 bed sheets were randomly collected from 585 hotels in China in 2016 and the pH values were determined. Results The pH test showed that the towels and bed sheets were slightly alkaline. Phe average pH value of towel samples was &12 and the qualified rate was 23.4%(906/3 872). The average pH value of bed sheets was 8.31 and the qualified rate was 19.8%(741/3 742 ). The multi-factor analysis showed that outsourced cleaning and disinfectioin through delivery way (OR= l .488, 95%CI: 1.192-1.857), lower star ratings of hotel (0R = 1.305, 95%CI: 1.152-1.478) were associated with unqualifrid pH value of bed sheets;Lower star ratings of hotel (OR = 1.259, 95%CI: 1.127-1.406) was associated with unqualifeid pH value of towels. Conclusion The public sharing textiles (towels and bed sheets) in hotels in China are slightly alkaline, outsourced cleaning and disinfection through delivery way and lower star ratings of hotel are the influencing factors. The hygienic supervision on towels and bed sheets in hotels should be strengthened in the future.
