Abstract: Objective To explore the effects of age on the prognosis of functional articulation disorders (FAD). Methods A total of 166 patients diagnosed with FAD were adopted as the research objects.After the patients'phonetic intelligibility (PI) was evaluated, the correlation and simple linear regression analysis for PI and age were carried on. Results The PI of the FAD patients was positively correlated with age (r_s=0.420).The result of simple linear regression analysis showed that the determination coefficient of age to PI was 0.193. Conclusion Age has some effect on the prognosis of FAD, but it is not the the main and the only factor.The patients with FAD should be cured in time at about 4 to 6 years old.

摘要： 目的 探讨年龄对功能性构音障碍(functional articulation disorders, FAD)预后的影响, 以期为FAD患儿的疾病指导和治疗提供依据。方法 选择166例FAD患儿为研究对象, 测得患儿的语音清晰度(phonetic intelligibility, PI)后, 对患儿PI和年龄的关系进行关联性分析和简单线性回归分析。结果 FAD患儿PI与年龄存在正相关(r_s=0.420), 经简单线性回归分析得年龄对PI的决定系数为0.193。结论 年龄对FAD的预后有一定的影响, 但并不是主要和唯一因素。FAD患儿应当在4～6岁期间得到及时矫正。
