BackgroundRecent reports estimate the prevalence of autism-spectrum conditions in the UK to be 1%.AimsTo use different methods to estimate the prevalence of autism-spectrum conditions，including previously undiagnosed cases，in Cambridgeshire.MethodWe carried out a survey of autism-spectrum conditions using the Special Educational Needs（SEN）register.向参与学校分发了一份诊断调查表，由其分发给所有5-9岁儿童的家长。主流小学人口进行筛选未知cases.ResultsThe患病率估计产生的SEN登记和诊断调查分别为94每10000和99每10000。共有11名儿童在筛查和评估后接受了自闭症谱系疾病的研究诊断。已知病例与未知病例的比例约为3：2（遵循统计加权程序）。两者合计，我们估计患病率为157每10000，包括以前未确诊的cases.ConclusionsThis研究的影响，规划诊断，社会和卫生服务。
BackgroundRecent reports estimate the prevalence of autism-spectrum conditions in the UK to be 1%.AimsTo use different methods to estimate the prevalence of autism-spectrum conditions, including previously undiagnosed cases, in Cambridgeshire.MethodWe carried out a survey of autism-spectrum conditions using the Special Educational Needs (SEN) register. A diagnosis survey was distributed to participating schools to be handed out to parents of all children aged 5-9 years. The mainstream primary school population was screened for unknown cases.ResultsThe prevalence estimates generated from the SEN register and diagnosis survey were 94 per 10000 and 99 per 10000 respectively. A total of 11 children received a research diagnosis of an autism-spectrum condition following screening and assessment. The ratio of known:unknown cases is about 3:2 (following statistical weighting procedures). Taken together, we estimate the prevalence to be 157 per 10000, including previously undiagnosed cases.ConclusionsThis study has implications for planning diagnostic, social and health services.
