The peak of\u0000 foodborne illness incidents in schools was in June and September. The largest number\u0000 of incidents occurred in middle school canteens and primary school canteens (all 12).\u0000 The number of reported incidents (12) and the number of cases of foodborne diseases\u0000 (371) in schools caused by cereals and their products were the largest. Pathogenic\u0000 bacteria and their toxins were the main pathogenic factors that caused the outbreaks\u0000 of foodborne diseases in schools, accounting for 78.26% of the identified causes.\u0000 Bacillus cereus was the top pathogens causing foodborne diseases outbreaks in schools.\u0000 The pathogenic factor that caused the largest number of cases was Diarrheogenic Escherichia\u0000 Coli, and the pathogenic factor that caused the death cases was poisonous mushrooms.\u0000 Apart from unexplained incidents, improper processing was the main link leading to\u0000 foodborne diseases outbreaks in schools.\u0000 Conclusion The primary and middle school students are the group with high incidence of foodborne\u0000 diseases in schools. The supervision and management of school canteen should be strengthened\u0000 in summer to prevent the outbreak of bacterial foodborne diseases caused by improper\u0000 processing and storage of grain food.\u0000 【摘要】 目的 分析河南省 2011—2020 年学校食源性疾病暴发事件的流行病学规律及特点, 为有效防控学校食源性疾病 暴发事件提供依据。\u0000 方法 对国家食品安全风险评估中心的食源性疾病暴发监测系统报告的 2011—2020 年河南省学校 食源性疾病暴发事件进行流行病学统计分析。\u0000 结果 河南省 10 年间共报告学校食源性疾病暴发事件 47 起, 累计发病人 数 1 258 人, 住院人数 701 人, 死亡 1 人。河南省学校食源性疾病暴发事件报告起数前\u0000 4 位的城市为郑州市、驻马店市、信 阳市, 新乡市。学校食源性疾病事件高峰期是 6 和 9 月。中学食堂和小学食堂导致的事件数最多 (均为 12 起)。粮食制品 引起的学校食源性疾病上报事件数和发病人数最多\u0000 (14 起, 371 人)。致病菌及其毒素是引起学校食源性疾病暴发事件的 主要病原因子, 占查明原因事件数的 78.26%。引起学校食源性疾病暴发事件最多的致病菌是蜡样芽孢杆菌,\u0000 引起发病人 数最多的致病因素是致泻大肠埃希菌, 引发死亡病例的致病因素是毒蘑菇。除原因不明的事件外, 加工不当是导致学校食 源性疾病暴发事件的主要环节。\u0000 结论 中小学生是学校食源性疾病高发群体, 应加强夏秋季学校食堂的监督和管理, 预防 粮食类食品加工储存不当导致的细菌性食源性疾病暴发事件。","PeriodicalId":106801,"journal":{"name":"Chinese Journal of School Health","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127202318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Blackboard reflectance, average illumination of blackboard and desk\u0000 are the important determinants for poor vision of primary and secondary school students.\u0000 Creating effective classroom lighting scheme is crucial for vision health among students.\u0000 【摘要】 目的 了解天津市中小学校教室采光照明和学生视力不良的关系, 为有针对性地制定中小学生视力保护措施提 供参考依据。\u0000 方法 于 2020 年 9—10 月, 采用分层整群抽样的方法, 选取天津市 89 所中小学共 623 间教室、24 713 名学生 为研究对象。采用照度计监测教室采光照明环境,\u0000 标准对数视力灯箱检测学生裸眼视力。采用 SPSS 24.0 进行 χ\u0000 2 检验、方 差分析和二元 Logistic 回归分析。\u0000 结果 天津市中小学生视力不良检出率为 67.86%, 黑板反射比、黑板面平均照度、黑板 面照度均匀度、课桌面平均照度、课桌面照度均匀度合格率分别为 58.11%, 53.13%,\u0000 73.19%, 66.61%, 75.12%。单因素分析 显示, 黑板反射比、黑板面平均照度、课桌面平均照度、课桌面照度均匀度是否合格对中小学生视力不良影响差异均有统计\u0000 学意义 (χ\u0000 2 值分别为 311.29, 62.54, 61.71, 6.59, P 值均<0.05)。多因素 Logistic 回归分析显示, 黑板反射比、黑板面平均照 度、课桌面平均照度不合格与中小学生视力不良均呈正相关 [\u0000 OR 值 (\u0000 OR 值 95%\u0000 CI) 分别为 1.19(1.11~1.27), 1.27(1.17~1.37), 1.11(1.02~1.20), P 值均<0.05]。\u0000 结论 天津市中小学生视力不良问题较严重, 黑板反射比、黑板面平均照度、课 桌面平均照度是中小学生发生视力不良的重要影响因素, 应营造良好的教室采光照明环境。","PeriodicalId":106801,"journal":{"name":"Chinese Journal of School Health","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123753116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
