چکیده

مقدمه: هدف از پژوهش حاضر مقایسه آلودگی به انگل توکسوپلاسما گوندای و پرخاشگری در کودکان مبتلا به اختلال اوتیسم و بهنجار می­باشد. طرح این پژوهش از نوع علی-مقایسه‌ای و از نظر هدف، کاربردی است.
روش ها: نمونه مورد بررسی شامل100 نفر که 50 نفر آنها را کودکان مبتلا به اوتیسم و 50 نفر آنها را کودکان بهنجار با سنین بین 3 تا 12 سال تشکیل می­دهند که از لحاظ سن، وضعیت اجتماعی-اقتصادی، شدت اختلال، عدم ابتلاء به بیماری­های حاد جسمانی و روانی و سایر متغیرهای مورد نظر در پژوهش کاملاً همگون بودند و با استفاده از نمونه‌گیری تصادفی  به دو گروه (آزمایش و کنترل) تقسیم شدند. از هر یک از افراد گروه به میزان Ml  5نمونه خونی جهت بررسی آلودگی به انگل توکسوپلاسما اخذ شد. جهت بررسی فرضیه­های تحقیق از آزمون غیر پارامتریک کای دو، یو من ویتنی، کروسکال والیس برای تحلیل داده‌ها استفاده شد، ابزار مورد استفاده در پژوهش، مقیاس پرخاشگری پیش دبستانی (واحدی و همکاران، 1387) و الایزا ریدر (Elisa redder) که به منظور قرائت نتایج تست (خون) طراحی شده است.
یافته ها: نتایج حاصل نشان داد که کودکان اوتیسم، میزان آلودگی بیشتری به انگل توکسوپلاسما گوندای نسبت به گروه بهنجار داشتند. همچنین کودکان آلوده به این انگل، پرخاشگری بیشتری نسبت به گروه غیر آلوده داشتند.
نتیجه گیری: در گروه کودکان اوتیسم، کودکان اوتیسمی که به این انگل دچار بودند، پرخاشگری بیشتری نسبت به کودکان اوتیسم غیر آلوده به انگل نشان دادند.

چکیده [English]

Introduction: This study aimed to compare the infection of ToxoplasmaGondii and aggression in autism and normal children.
Methods: The research method was causal-comparative while it is considered as an applied research. The participants included (N=100) 50 autistic children and 50 normal children ranging from 3 to 12 years old; they were homogenous in terms of age, socio-economic status, the severity of the disorder, lack of physical and mental illness, and other criteria considered in this research. Then the researchers divided them randomly into two groups as experimental and control. Of each group, 5ml blood samples were collected to assess the prevalence of toxoplasma. To investigate the hypothesis, non-parametric Kai-Dwo test, Mann-Whitney U test, and Kruskal-Wallis test were used to analyze the data. The instruments were preschool aggression scale (Vahedi et al, 1387), and Elisa reder to essay the blood sample test.
Results: The results showed that children with autism had more pollution to Toxoplasma Gondii in comparison with the normal group.
Conclusion: Children with autism who had parasites were more aggressive than non-infected children who had autism (P=0/05).
