目的:评价综合防治砷中毒后相关健康行为及病情,为采取针对性干预措施提供依据。方法:于2013年选择兴仁、安龙2个燃煤污染型砷中毒病区县,随机抽取2个病区村作为调查点,调查禁采高砷煤管理情况,按照《地方性砷中毒诊断标准》(WS/T 211-2001)对调查点所有暴露人群进行检查和判定,并采集病人尿样30份,按二乙基二硫代氨基甲酸银-三乙醇胺分光光度测定方法(WS/T 28)检测尿中砷含量。每个调查点随机抽取10户家庭,入户调查病区村家庭健康相关生活行为。结果:调查点11个高砷煤矿管理到位,无人偷采。调查砷暴露人群2360人,砷中毒病例数324例,患病率13.73%,无新发病例,尿砷含量在0.0~0.056mg/L之间,几何均数为0.0114 mg/L。家庭健康相关生活行为正确率达100%。结论:病区家庭相关健康生活行为方式已经形成,砷污染得到有效控制,无新发病例。
OBJECTIVE: To evaluate the related health behaviors and conditions after comprehensive prevention and treatment of arsenic poisoning, and provide the basis for the targeted interventions. Methods: Two coal-burning arsenic poisoning counties in Xingren and Anlong were selected in 2013. Two ward villages were randomly selected as survey sites to investigate the management of forbidden high-arsenic coal mining. According to the "Local arsenic poisoning diagnosis (WS / T 211-2001) were used to check and determine all the exposed population at the investigation point. Thirty samples of urine samples were collected and analyzed by silver diethyldithiocarbamate-triethanolamine spectrophotometry (WS / T 28) Detection of urinary arsenic content. Ten households were randomly selected from each survey site to investigate the family-related health behaviors of the ward villages. Results: 11 high-arsenic coal mine management sites were surveyed and no one stole any data. A total of 2,360 people were exposed to arsenic, 324 cases were arsenic poisoning, with a prevalence of 13.73%. No new cases were found. The urinary arsenic contents ranged from 0.0 to 0.056 mg / L, and the geometric mean was 0.0114 mg / L. Family health-related life behavior correct rate of 100%. Conclusion: Ways and means of family health behaviors have been formed, arsenic pollution has been effectively controlled and no new cases have been found.
