碘缺乏病病区儿童精神运动障碍与轻度智力落后的关系

Analyses of the relation between psychomotor obstruction and mild delay of intelligence of children in iodine deficiency disorder regions

目的 预测和评价碘缺乏病病区轻度智力落后儿童,评估亚克汀病患病率。方法 拟合多元Logis-tic回归模型预测分析儿童智力落后与精神运动异常的关系,并分析教师评语、数学和语文成绩等因素的影响。结果 儿童轻度智力落后与津医精神运动成套测验（JPB）异常检出率分别为1.63％,3.26％。JPB得分与智商（IQ）得分有显著相关关系;Logistic回归分析显示,JPB检出轻度智力低下儿童的灵敏度达80％,OR=55.9（95％CI:5.1～999.0,P<0.01）。结论 JPB可用于预测和评价碘缺乏病病区轻度智力低下儿童,灵敏度较高,而且病区中JPB异常检出率明显高于智力落后儿童的检出率,可作为亚克汀病患病率的有效估计。

Objective To predict and evaluate mild delay of intelligence of children and the incidence of sub -critine in iodine deficiency regions. Methods Multiple Logistic regression model was fitted to predict and analyze the relation between delay of intelligence and psychomotor obstruction of children, and other factors such as grade of teacher comments, marks of Chinese and math were analyzed in the mo'del as covariates. Results In children the positive rate of mild delay of intelligence and that of Jinyi psychomotor test battery(JPR) were 1.63% and 3. 26%, respectively. JPB and IQ were significantly correlated. Analyses of Logistic regression showed that the sensitivity predicted by JPB was 80% , OR = 55.9(95%CI:5.1～999.0, P<0. 01). Conclusions JPB was applied to predict and evaluate mild delay of intelligence of children, and has higher sensitivity and can be used to effectively estimate prevailence of sub-cretine.
