India is the second most populous country of the world. A large portion of the population of this country is below 20 years of age but still there is a paucity of information about the prevalence and incidence of many developmental disorders. This study was planned to estimate the prevalence of autism spectrum disorders (ASDs) in the selected areas (tribal, rural, and urban) of a northern state of India, Himachal Pradesh.
A cross-sectional two-phase study was conducted covering all the children in the range of 1-10 years of age. Phase one included screening of all the children in the age group of 1-10 years, with the help of an indigenous assessment tool for autism. The sociodemographic profile of the participants was also recorded during phase one. Phase two involved the clinical evaluation of individuals who were suspected of autism on screening.
The results show a prevalence rate of 0.9/1000. The highest prevalence rate was observed in the rural area.
Socioeconomic status (SES) may be one of the fundamental indicators for ASDs in India.
印度是世界上人口第二多的国家。该国很大一部分人口年龄在20岁以下，但关于许多发育障碍的患病率和发病率的信息仍然匮乏。本研究旨在估计印度北部喜马偕尔邦选定地区（部落、农村和城市）自闭症谱系障碍（ASD）的患病率。
进行了一项横断面两阶段研究，涵盖所有1至10岁的儿童。第一阶段包括借助一种本土自闭症评估工具对所有1至10岁年龄组的儿童进行筛查。在第一阶段还记录了参与者的社会人口学特征。第二阶段涉及对筛查中疑似自闭症的个体进行临床评估。
结果显示患病率为0.9/1000。农村地区的患病率最高。
社会经济地位（SES）可能是印度自闭症谱系障碍的基本指标之一。
