摘要
目的调查分析三峡建坝后库区自然生态和社会环境及人群生产生活方式、健康知识水平等因素对血吸虫病传播的潜在影响.方法搜集建坝后自然环境和社会发展信息;问卷调查试区居民、后靠移民生产生活方式及血吸虫病知识状况,分析目标人群血吸虫病危险行为状况及相互关系.结果建坝后水流变缓,水库冬蓄夏泄在库岸形成消落带.库区居民饮用水和生活用水来源主要为河水,分别占68.7%和75.8%;因生产生活需要经常接触江河水比例为45.6%.移民中待业和外出务工人群比例分别由搬迁前的5.7%和5.7%上升为29.3%和18.7%;无害化厕所使用比例88.6%,移民饮用水和生活用水来源主要为自来水,分别占85.4%和87.O%.居民血吸虫病知晓率为3.6%.结论库区自然生态及人群生产生活方式、防病知识匮乏是血吸虫病传播的危险因素;移民区卫生状况改善和库区经济的发展不利于血吸虫病的传播和流行,但移民中外出务工人员的增加对传染源的输入具有潜在危险性.
Objective To investigate the changes in natural ecology and social environment after the construction of the dam in the Three Gorges Reservoir area,and to understand the social behavior status and education backgounds of the local residents,and to analyze the potential impact of these factors on schistosomiasis spreading.Methods Data of nature and social econormy afer the construction of the dam in the Three Gorge area were collected,and a cros8 sectional study with questionnaire survey on information including social demographic characteristica,people'g production and life style,knowledge about schistosomiasis was conducted among natives,emigrations.Results After the construction of the dam,88 the stream beceame slower,the water-level fluctuating zone on the bank of the reservoir was formed.The main soumrce of drinking water and daily life activity are mainly depends on the river supplyins(accounting about 68.7%and 75.8%,respectively);due to the needs of farming,washing cloths and vegetables,45.6%of resident had a close contact with river water.People with away-from-home employment among emigrations were increased from 5.7%to 18.7%.The proportion of using bygienie lavatory was 88.6%.The main source of water for drinking and daily life among emigrations was tap water(85.4%and 87.0%).The reaidents had no awareness about the health hazard for schistomiais,with less healh information Conclusion The natural environment of rervoir areas and the life style are risk factors for the spread of schistosomiasis.The improved sanitation condition and the economy construction after the construction of the dam is propitious to keeping away from the introduction of schistomisis.However,people with away-rom-home employment amnong emigrations are still at risk of schistosomiasis.
