津医精神运动成套测验用于碘缺乏病的评估效果

Application of JinYi psychomotor test battery to evaluate iodine deficiency disorders

目的 研究津医精神运动成套测验 (JPB)用于评估碘缺乏病 (IDD)可持续性消除的意义和作用。方法 在进入可持续消除 IDD的江苏地区 ,以人口容量比例概率 (PPS)抽样法用 JPB和中国联合型瑞文测验图册和农村儿童智商常模 (CRT- C2 )测定 30个点目标人群的精神运动发育状况和智商 (IQ)值。结果 116 0名 8～ 10岁学生 JPB值总 T分水平为 36 9.6± 35 .8,95 %可信区间 2 99.4～ 4 39.8,频数呈常态分布 ,JPB值异常率为0 .7% ,影响率为 5 .4 %。JPB值与 IQ值呈非常显著正相关关系 (γ=0 .2 4 ,P<0 .0 1) ,直线回归方程 Y=317.97+0 .5 2 0 8IQ。IQ<70组异常率 5 .8% ,随 IQ值增加 JPB值异常逐渐减少至不出现。结论 JPB作为反映人群大脑损害的指标之一 ,列入

Objective To examine the effectiveness of Jin Yi psychomotor test battery(JPB) in evaluating the status of sustainable elimination ofiodine deficiency disorders(IDD).Methods Intelligence Quotient was measured by using modified Raven Progressive Matrix (CRT C 2), and psychomotor by JPB in each of 1160 school children aged 8~10 years selected for the study in Jiangsu Province, China.Results The JPB scores were normally distributed, with mean score at 369.6±35.8 (95% CI:299.4~439.8). The abnormal rate (JPB≤280) was 0.7%, the borderline abnormal rate (280<JPB≤315) 5.4%. A significant correlation between JPB and intelligence quotient(IQ) was found.(γ=0.24,P<0.01).The linear regression equation was JPB=317.97+0.5208 IQ.As IQ increases,the JPB abnormality rate fades.Conclusions JPB score can be used as an indicator to evaluate the status of sustainable elimination of IDD.
