目的对比先天性甲状腺功能减低症(congenital hypothyroidism,CH)学龄期儿童与正常儿童的视听整合持续测试表现特征,探讨患儿反应控制力及持续性注意力损害特点,为进一步提高治疗效果提供理论依据。方法运用视听整合持续操作测试对36例CH儿童[男童16例,女童20例,年龄6~12.9岁,平均年龄(8.64±2.51)岁]和与之匹配的36名正常儿童进行测试,对其测试结果进行比较分析。结果两组儿童在听觉注意力、视觉注意力以及综合注意力商数上的差距具有统计学意义,病例组儿童较正常组儿童得分低。在反应控制力方面,两组儿童在听觉控制力和综合控制力比较上差异不具有统计学意义,而在视觉控制力上的比较,两组儿童的差异具有统计学差异。结论 CH学龄期儿童在持续注意力上存在缺陷,以视觉注意力缺陷为主要表现,对CH儿童的治疗目标需包括提高持续注意力方面。
Objective To compare the characteristics of audiovisual integration test in congenital hypothyroidism (CH) school-aged children and normal children, and to explore the characteristics of children’s responsiveness control and persistent attention impairment in order to provide a theoretical basis for further improving the therapeutic effects . Methods Sixty-six CH children (16 boys, 20 girls, aged 6-12.9 years, mean age 8.64 ± 2.51 years) and matched 36 normal children were tested by audiovisual integration continuous operation test. The test results for comparative analysis. Results The differences between the two groups in auditory attention, visual attention and comprehensive attention quotient were statistically significant. Children in the case group had lower scores than children in the normal group. In response control, the two groups of children in auditory control and comprehensive control force difference was not statistically significant, while in visual control, the difference between the two groups of children with a statistically significant difference. Conclusions CH school-age children have persistent deficits in attention, with visual attention deficits as the main manifestation. Children with CH should be treated with the goal of improving their ongoing attention.
