Abstract:
Objective To investigate the current condition and risk factors of Keshan disease (KD) in Shandong Province,and to provide a scientific basis for prevention and control of KD.Methods Based on the 2014 scheme of KD surveillance,residents in 38 surveillance sites of 19 counties (cities,districts) were surveyed by questionnaire survey,physical examination,electrocardiograms (ECG),X-ray or echocardiography.At the same time,some residents' hair,grain and soil samples were collected,and the content of selenium in the internal and extemal environment was tested.KD was evaluated in Shandong Province based on the "National Standard of Evaluation Method for Key Endemic Disease Control and Elimination".Results ①In 38 monitoring sites,16 168 residents were surveyed and 164 cases of KD were detected (in which 149 cases of potential,15 cases of chronic),the detection rate was 1.014％.② Totally 2 497 samples of hair (n =763),food (wheat:n =687,corn:n =751) and soil (n =296) were collected and the selenium contents in hair was (0.379 ± 0.120) mg/kg,in wheat and corn were (0.025 ± 0.009) mg/kg and (0.016 ± 0.007) mg/kg,and in soil was (0.132 ± 0.046) mg/kg.③According to the national standard of evaluation content and decision criteria for KD,6 counties achieved the elimination index and 13 counties were in the control level in Shandong Province,the county proportion of eliminating KD was 31.58％ (6/19).Conclusions ①The current condition of KD in Shandong Province remains relatively stable.Internal environment selenium content is increased significantly due to improvement of people's living standard and dietary nutrition.②There is still a gap between the number of counties eliminated KD and the "elimination targets" required by the state in Shandong Province.It is recommended to continue to strengthen the team construction in prevention and control of KD and to enhance the investment of money,at the same time,to establish a long-term working mechanism in prevention and control of KD.
