目的掌握本市农村7-12岁小学生精神运动(JPB)水平,了解轻度缺碘或补碘不足所致的精神运动发育障碍。方法 JPB测验采用“中国第二次修订的《津医精神运动成套测验》(JPB)”指导书,用农村儿童JPB常模表判定标准。实验组选在秦皇岛市郊区的黄土坎小学和抚宁县小部落小学7～12岁小学生。对照组选在承德市郊区狮子沟小学和隆化县韩麻营小学。结果 JPB水平:实验组郊区农村小学生总T分为384.83±86.75,对照组总T分为336.48±96.51,相比差异显著;其中除划消数字、视觉保持组外,各组相比都有显著性差异;实验组县区农村小学生总T分为391.52±81.27,对照组总T分为360.22±80.41,相比差异不显著。其中选择反应时、连接数字、转动插棒3组相比有显著性差异。IQ﹤69的学生JPB异常率,郊区农村黄土坎为8.33%、狮子沟为16.66%;县区农村小部落为3.33%,韩嘛营为12.00%。结论实验组农村小学生JPB水平明显高于对照组农村小学生,相比有非常显著性差异,而IQ﹤69的学生JPB异常率明显低于对照组。
Objective To understand the level of JPB in pupils aged 7-12 in rural areas of this Municipality to understand the mental retardation caused by mild iodine deficiency or iodine insufficiency. Methods The JPB test was conducted using the “revised version of the Chinese Medical Psychomotor Fitness Test (JPB)” guidebook, which was judged by the JPB model table for rural children. Experimental group selected Qinhuangdao suburbs of Huangtukan primary school and Funing County tribal primary school aged 7 to 12 primary school students. The control group was selected in the Shizigou primary school on the outskirts of Chengde city and Hanmaoying primary school in Longhua county. Results JPB level: the experimental group rural suburbs primary school students total T was 384.83 ± 86.75, the control group total T was 336.48 ± 96.51, compared with the difference was significant; except in addition to the number and visual preservation group, the group compared with significant Sex difference; experimental group county rural primary school total T is divided into 391.52 ± 81.27, control group total T is divided into 360.22 ± 80.41, compared with the difference was not significant. Which choose the reaction, the connection figures, rotating insert 3 groups compared to significant differences. The abnormal JPB rate of students with IQ <69 was 8.33% in rural areas, 16.66% in Lizigou, 3.33% in rural small counties and 12.00% in Hanmaying. Conclusions The JPB level of primary school pupils in experimental group is obviously higher than that of rural primary school pupils in control group, and the abnormal rate of JPB in IQ <69 students is obviously lower than that in control group.
