摘　　要：目的分析石家庄市婴幼儿游泳场所实施干预措施后的效果,为改善石家庄市婴幼儿游泳场所卫生现状提供科学依据。方法2021—2022年,采用分层随机抽样的方法抽取石家庄市7个主城区(县)的婴幼儿游泳场所,在每个区(县)随机抽取7~8个场所。2023年按照上述方法进行抽样,每个区(县)抽取场所编号为奇数的定义为干预组,编号为偶数的定义为对照组。对照组场所维持其原有的日常消毒方式,干预组对婴幼儿游泳场所实施3个月的干预措施,分别对游泳池水、室内空气质量、公共用品用具及从业人员手卫生状况进行监测。结果2021—2022年,共检测婴幼儿游泳场所池水水样324份,池水合格率为22.22%;2023年干预组场所和对照组场所均检测池水水样78份,池水的总合格率分别为64.10%和41.03%,干预组场所游泳池水总体合格率高于对照组场所,差异有统计学意义(χ^(2)=8.330,P=0.004),2023年干预组场所游泳池水中尿素、pH值、细菌总数、游离性余氯指标合格率分别为100.00%、100.00%、64.10%和51.28%,合格率高于2021—2022年,差异有统计学意义(P<0.05)。2021—2022年共检测室内空气样本273份,室内空气合格率20.51%,2023年干预组、对照组场所分别检测室内空气样本均为78份,合格率分别为89.74%,75.64%,差异有统计学意义(χ^(2)=5.419,P=0.020),2023年干预组场所室内空气中水面照度、相对湿度、室温、PM10、PM2.5指标检测合格率分别为100.00%、100.00%、100.00%、91.03%和98.72%,合格率高于2021—2022年,差异有统计学意义(P<0.05)。2021—2022年共检测微生物样本1181份,总合格率85.86%,2023年干预组场所和对照组场所检测微生物样本分别为249份和248份,微生物样本的合格率分别为89.16%和81.85%,差异有统计学意义(χ^(2)=5.347,P=0.021),2023年干预组场所婴幼儿游泳场所从业人员手细菌总数合格率为92.31%,2021—2022年从业人员手细菌总数合格�Objective To analyze the effects of implemented intervention measures on the hygiene conditions of infant swimming facilities in Shijiazhuang City,providing scientific evidence for improving the sanitation standards of these facilities.Methods From 2021 to 2022,a stratified random sampling method was employed to select infant swimming facilities in seven main urban areas(counties)of Shijiazhuang City,with 7-8 facilities randomly chosen from each district.In 2023,a similar sampling method was carried out,designating oddnumbered facilities as the intervention group and even-numbered facilities as the control group.The control group maintained their original daily disinfection practices,while the intervention group underwent a 3-month intervention.Monitoring was conducted on swimming pool water,indoor air quality,public items,and hand hygiene of staff.Results From 2021 to 2022,a total of 324 water samples from swimming pools were tested,with a compliance rate of 22.22%.In 2023,both the intervention and control groups had 78 water samples tested,with overall compliance rates of 64.10%and 41.03%,respectively.The intervention group demonstrated a significantly higher compliance rate than the control group,and the difference was statistically significant(χ^(2)=8.330,P=0.004).In 2023,the compliance rates for urea,pH value,total bacterial count,and free residual chlorine indicators in swimming pool water in the intervention group were 100.00%,100.00%,64.10%,and 51.28%,respectively,which were significantly higher than those in 2021—2022(P<0.05).Additionally,273 indoor air samples were tested from 2021 to 2022,with a compliance rate of 20.51%.In 2023,78 indoor air samples were tested in the intervention group and control group,with compliance rates of 89.74%and 75.64%,respectively,indicating a significant difference(χ^(2)=5.419,P=0.020).In 2023,the compliance rates for water surface illumination,relative humidity,room temperature,PM10,and PM2.5 indicators in the indoor air of the intervention group were 100.00%,100.00%,
