攀枝花市克山病发病周期及粮食中硒含量论证研究

Study on epidemiological characteristics of Keshan disease and selenium content in foodstuff in Panzhihua city

目的 对攀枝花市克山病流行周期及粮食中硒含量进行论证研究。方法 按年度及月份对攀枝花市1967~2013年报告的克山病病例进行汇总分析。比较2006年和2014年当地粮食标本硒含量检测结果。分析粮食标本硒含量与克山病报告情况的相关性。结果 攀枝花市克山病发病有一定的周期性,高发期持续约3~5年,7~9月为高发月份。2014年粮食标本硒含量结果与2006年检测结果比较差异无统计学意义（P〉0.05）。就攀枝花市整体而言,粮食中硒含量与克山病发病呈正相关（P〈0.05）;就曾有克山病病例报告的乡镇而言,粮食中硒含量与克山病发病无相关性（P〉0.05）。结论 克山病发病可能与粮食中硒含量无相关性。

Objective To evaluate Keshan disease′s epidemic period and selenium content in foodstuff in Panzihua .Methods Data of incidence of Keshan disease in Panzhihua ,from 1967 to 2013 ,were analyzed .Selenium content in foodstuff ,detected in 2006 and 2014 ,were compared .Correlation between incidence of Keshan disease and selenium content in food stuff were analyzed .Results Incidence of Keshan disease was with periodicity ,the high incidence period continued 3 - 5 years ,and the high incidence months were Jul .and Sep .Selenium content in foodstuff were without significant differences between 2014 and 2006（P〉 0 .05） .Incidence of Keshan disease could be positively correlated with selenium content in foodstuff in the city（P〈 0 .05） ,but were without correlation in township with reported Keshan disease cases（P 〉 0 .05） .Conclusion Incidence of Keshan disease could be without correlation with selenium content in foodstuff .
