Objective To understand the awareness level of iodine deficiency (ID) impairments and the attitude on edible iodized salt,and its consumption among doctors and nurses in cities,in order to provide scientific evidence for health education on iodine deficient disorders (IDD) in the future.Methods The questionnaire was self-designed,and spread through the web page of Wenjuanxing,an online server company,from May 6 to June 6,2017.At the end of the survey,a total of 481 valid questionnaires were reclaimed,in which ratio of gender was female 63.8％ (307/481),male 36.2％ (174/481).The data were analyzed by SPSS 22.0,including logistic regression analysis with backward according to the statistical significant level of P ＜ 0.05.Results Among doctors and nurses,90.4％ (435/481) knew ID impairments;72.8％ (350/481) answered intelligent disability as the most serious problem of ID;55.5％ (267/481)misunderstood that the areas in which they lived were not ID areas,although all cities surveyed were ID areas;41.0％ (197/481) of doctors and nurses misunderstood that coastal residents did not need to consume iodized salt.About the evaluation of iodine nutrition status of current population,15.6％ (75/481) of respondents judged as iodine excess.About consuming edible salt,76.3％ (367/481) selected iodized,9.6％ (46/481)non-iodized,and 14.1％ (68/481) both iodized and non-iodized.The results of logistic regression analysis showed the factors that prevents health care workers from choosing iodized salt were:"living in coastal areas","think him or her as iodine adequate","know that iodine deficiency can affect the development of children but still adhere to the consumption of non-iodized salt";the factors that promoted the choice of iodized salt for medical staff were "insist on buying iodized salt,and do not choose non-iodized salt",and 75.8％ (238/314)of them knew that intelligent disability as the most serious problem of ID.Conclusions Most doctors and nurses have high level of knowledge on ID and its control.But lack of information,as well as misunderstanding of "coastal areas iodine adequate" and worry about "excess iodine causes thyroid diseases and cancer",which would hinder the active consumption of iodized salt.Health education for them should be conducted through professional ways,stressing on the threaten of ID environment,sharing the information about national and local progress on control of IDD and iodized salt safety,and clarifying the relationship between iodine salt or iodine and thyroid cancer and nodules.

目的:研究丹佛发育筛查测验(DDST)用于维族婴幼儿的筛查效度.方法:80名未见躯体疾病的维族婴幼儿纳入研究.以格塞尔发育诊断量表(Gesell)为效标,进行Gesell和DDST的个别测试.效度评价采用灵敏度、特异度、假阳性率、假阴性率、符合率和工作特征曲线下面积(AUC).结果:DDST迟缓筛查率为17.50%,语言能区迟缓率最高,占比达56.00%.以Gesell发育商DQ≤75分为切点时,DDST筛查的灵敏度、特异度、假阳性率、假阴性率和符合率分别为100.00%、85.71%、14.29%、0.00和86.25%,AUC为0.93(P<0.01).以Gesell发育商DQ<85分为切点时,DDST的灵敏度、特异度、假阳性率、假阴性率和符合率分别为69.23%、92.54%、7.46%、30.77%和88.75%,AUC为0.80(P<0.01).结论:用于筛查Gesell异常诊断的维族婴幼儿时,DDST具有较高筛查价值;用于筛查Gesell可疑诊断的婴幼儿时,DDST筛查能力中等.语言可能影响了DDST的筛查效度,可考虑建立维族常模.
