<正>河南省煤炭资源丰富,是产煤大省,某些煤矿不能采用综采技术,机械化程度低,人工作业量大,接尘工人人数多。资料[1]表明,煤尘是煤矿的主要职业危害因素之一,其对接尘工人肺通气功能有损伤,易导致尘肺、肺部炎症、结核及肺气肿等肺部疾病的发生[2]。定期监测煤炭作业场所粉尘浓度,评价煤矿作业环境卫生质量是预防粉尘危害的重要内容[3]。该研究对河南省某煤矿煤尘2007年至2008年和2009年至2010年的煤尘监测资料回顾,并对相应年度新矿工的肺通气情况进行调查,探该煤矿

目的评价在中学生中开展学校和家庭生殖健康教育的效果,为进一步研究和实施提供依据。方法采用以学校为单位的干预性研究,干预模式采取单纯学校教育(干预1组)与家庭和学校同步教育(干预2组)。通过基线和终末两次问卷调查及学生和家长的小组访谈,比较干预前后、干预组和对照组以及两个干预组间学生生殖健康知识水平,来评价干预的效果。结果基线调查发现,中学生的生殖健康知识均较低,而初中生更低(均数仅为30.75分)。干预后发现,初中生中,干预对生殖生理知识的增加作用最大(两个干预组相对于对照组的增加差值分别为22.58和28.82),增加作用最小的是避孕知识(两个干预组相对于对照组的增加差值为0.65和6.84);两种干预方式比较,干预方式1对艾滋病、性病知识的增值作用较大,而干预方式2对生殖生理知识的增加作用较大,两种干预方式对避孕知识的增加作用无显著差别。结论干预提高了中学生的生殖健康知识水平,其中家庭和学校同步教育的效果更显著。
