BACKGROUND Children and adolescents with attention-deficit/hyperactivity disorder (ADHD) often have a co-occurring reading disorder (RD). The purpose of this research was to assess differences between children with ADHD without RD (ADHD-only) and those with ADHD and co-occurring RD (ADHD+RD). METHODS Using data from the U.S. Thomson Reuter Marketscan® Databases for the years 2005 through 2007, this analysis compared the medical records--including patient demographics, comorbidities, and medication use--of children (age < 18) with ADHD-only to those with ADHD+RD. RESULTS Patients with ADHD+RD were significantly younger, more likely to have received a procedure code associated with formal psychological or non-psychological testing, and more likely to have been diagnosed with comorbid bipolar disorder, conduct disorder, or depression. They were no more likely to have received an antidepressant, anti-manic (bipolar), or antipsychotic, and were significantly less likely to have received a prescription for a stimulant medication. CONCLUSIONS Relying on a claims database, there appear to be differences in the patient characteristics, comorbidities, and medication use when comparing children with ADHD-only to those with ADHD+RD.

患有和不伴有阅读障碍的 ADHD 儿童的患者特征、合并症和药物使用：一项回顾性队列研究。

背景 患有注意力缺陷/多动障碍 (ADHD) 的儿童和青少年通常同时患有阅读障碍 (RD)。本研究的目的是评估没有 RD 的 ADHD 儿童（仅 ADHD）与 ADHD 并同时发生 RD（ADHD+RD）的儿童之间的差异。方法 使用美国 Thomson Reuter Marketscan® 数据库中 2005 年至 2007 年的数据，该分析将患有 ADHD 的儿童（18 岁以下）的医疗记录（包括患者人口统计数据、合并症和药物使用情况）与仅患有多动症的儿童的医疗记录进行了比较多动症+RD。结果 ADHD+RD 患者明显更年轻，更有可能接受与正式心理或非心理测试相关的程序代码，并且更有可能被诊断出患有双相情感障碍、品行障碍或抑郁症。他们不太可能接受抗抑郁药、抗躁狂症（双相）或抗精神病药，并且不太可能接受兴奋剂处方。结论 依靠索赔数据库，将患有 ADHD 的儿童与患有 ADHD + RD 的儿童进行比较时，患者特征、合并症和药物使用似乎存在差异。
