The aim of this study was to investigate the association between adult ADHD screening scores and hospitalization due to pedestrian injuries in a sample of Iranian pedestrians. Through a case-control study, a case population of 177 pedestrians injured by the vehicles in road traffic crashes were compared with 177 controls who lacked a record of intentional or unintentional injuries enrolled from various wards of Imam Reza University Hospital which is a specialty teaching hospital located in the same city with similar referral level. The cases and controls had an age range of 18–65 years and were matched on gender and age. ADHD symptom profile was assessed using the Persian Self-report Screening Version of the Conner’s Adult ADHD Rating Scales (CAARS-S:SV). The association of ADHD screening score and pedestrian injuries was investigated using multiple binary logistic regression to investigate the independent effect of ADHD index score on belonging to case group. Both crude and adjusted odds ratios were reported. Men comprised 86.4% of the study subjects. The crude odds ratios for all the four ADHD subscales to be associated with pedestrian injuries were 1.05, 1.08, and 1.04 for the subscales A (attention deficit), B (hyperactivity/impulsiveness) and ADHD index respectively. However, the association for subscale A was not statistically significant with a borderline p-value. The final multivariate analysis showed that variables associated with pedestrian injuries in the road traffic crashes were ADHD Index score (OR = 1.06, 95% CI: 1.01–1.12); economic status (including household income and expenditure capacity); educational level and total walking time per 24 h. Adult ADHD screening score can predict pedestrian injuries leading to hospitalization independently from sex, age, economic status, educational level and pedestrian exposure to traffic environment (average walking time).

成人ADHD筛查分数和行人受伤造成的住院：病例对照研究。

这项研究的目的是调查伊朗行人样本中成人多动症筛查得分与行人受伤住院之间的关系。通过案例对照研究，比较了177名行人在道路交通事故中受伤的行人病例，与177名缺乏专门或特级教学医院伊玛目礼萨大学医院各个病房的有意或无意受伤记录的对照组位于相同推荐级别的同一城市。病例和对照的年龄范围为18-65岁，并按性别和年龄进行匹配。使用Conner成人ADHD评分量表（CAARS-S：SV）的波斯自我报告筛选版本评估ADHD症状。采用多元二元logistic回归分析ADHD筛查评分与行人伤害的关系，以探讨ADHD指标评分对病例组的独立影响。原油和调整后的优势比都报告。男性占研究对象的86.4％。与人行伤害有关的所有四个ADHD子量表的原始比值比分别为A（注意缺陷），B（多动/冲动）和ADHD指数为1.05、1.08和1.04。但是，亚尺度A的关联在具有临界p值的情况下在统计上并不显着。最终的多变量分析表明，与道路交通事故中的行人伤害相关的变量是ADHD指数评分（OR = 1.06，95％CI：1.01-1.12）；经济状况（包括家庭收入和支出能力）；每24小时的教育水平和总步行时间。成人ADHD筛查分数可以独立于性别，年龄，经济状况，教育程度和行人在交通环境中的接触（平均步行时间）来预测行人受伤导致的住院治疗。
