目的：探讨功能性构音障碍患儿的临床共患病及行为问题。方法：对112例确诊为功能性构音障碍的患儿,采用临床调查方法及DSM-IV注意缺陷多动障碍（ADHD）、口吃、抽动障碍及遗尿症诊断标准进行共患病调查，应用Conners父母问卷量表、儿童行为量表进行行为问题分析。结果：112例功能性构音障碍患儿中合并一种或一种以上共患病者占61.6%。中重度患儿共患病率高于轻度患儿。功能性构音障碍与语言障碍共患病率最高，为30.4%，其他依次为口吃18例(16.1%)，遗尿症15例(13.4%)，抽动障碍7例(6.3%)。学龄功能性构音障碍患儿与ADHD共患病率最高，达47.5%。儿童行为量表调查显示行为问题发生率为40.2%。Conners父母问卷量表调查结果显示57.1%存在一种或一种以上因子异常。结论：功能性构音障碍患儿合并共患病比例较高,且存在较多行为问题，在临床工作中应给予足够重视,注意检查及治疗。［中国当代儿科杂志，2009，11（3）：225-228］

OBJECTIVE: To study the incidences of comorbidities and behavioral problems in children with functional articulation disorders. METHODS: One hundred and twelve children with functional articulation disorders (aged 4-11 years) were enrolled. Their comorbidities were identified based on clinical investigations and the DSM-IV diagnosis criteria of attention deficit hyperactivity disorder (ADHD), stuttering, tic disorders and enuresis. Behavioral problems were evaluated by the Conners Parent Symptom Questionnaire and the Child Behavior Checklist. RESULTS: Sixty-nine patients (61.6%) had one or more comorbidities. The incidence of comorbidity in children with middle-severe functional articulation disorders was higher than in those with mild disorders. The most common comorbidity was language impairment (30.4%), followed by stuttering (16.1%), enuresis (13.4%), and tic disorders (6.3%). In school age children, ADHD (47.5%) was the most common comorbidity. The incidence of behavioral problems was 40.2% by the Child Behavior Checklist and 57.1% by the Parent Symptom Questionnaire. CONCLUSIONS: The children with functional articulation disorders have high incidence of comorbidity and many behavioral problems.［Chin J Contemp Pediatr, 2009, 11 (3):225-228］
