目的对2014年全国健康访谈调查(NHIS)中的发育障碍问题进行修改，包括问题的重新排序和自闭症谱系障碍(ASD)的新提问方式。这份报告审查了基于调查的对自闭症、智力残疾(ID)和任何其他发育迟缓(其他DD)的终生患病率的估计，包括独立的ASD问题、在ASD问题中包括特定的诊断、以及在其他DD问题之前的ASD问题，并将它们与前几年的估计进行比较。方法在NHIS中，从每个家庭中随机选择一名儿童作为详细问题的对象，调查内容包括健康状况、功能限制和卫生保健利用情况。父母被问及是否有医生或卫生专业人员告诉过他们，他们的孩子患有一系列发育障碍中的每一种。使用2011-2014年收集的数据计算了3-17岁儿童ASD、ID和其他DD的患病率估计值。结果根据2014年的数据估计的ASD患病率为2.24%，比基于2011-2013年数据的1.25%的年化患病率有显著增加。相比之下，其他DD的患病率从2011-2013年数据的4.84%显著下降到2014年数据的3.57%。从2011-2013年(1.27%)到2014年(1.10%)，ID的患病率没有显著变化。在调查的几年中，患有这三种情况中的任何一种的流行率都是恒定的。结论修订后的问题顺序和2014年国民健康状况调查中询问发育障碍的新方法可能会影响对这些疾病患病率的估计。在前几年，一些被诊断为ASD的儿童的父母很可能将这种发育障碍报告为其他DD，而不是ASD，或作为ASD的补充。在这些变化之后，2014年ASD估计与其他来源的ASD患病率估计更相似。
OBJECTIVES The developmental disabilities questions in the 2014 National Health Interview Survey (NHIS) were changed from previous years, including question reordering and a new approach to asking about autism spectrum disorder (ASD). This report examines survey-based estimates of the lifetime prevalence of ASD, intellectual disability (ID), and any other developmental delay (other DD) following the inclusion of a standalone ASD question, the inclusion of specific diagnoses in the ASD question, and the ASD question preceding the other DD question, and compares them with estimates from previous years. METHODS In NHIS, one child is randomly selected from each family to be the subject of detailed questions on health conditions, functional limitations, and health care utilization. Parents are asked if a doctor or health professional had ever told them that their child had each of a series of developmental disabilities. Prevalence estimates of ASD, ID, and other DD for children aged 3–17 years were calculated using data collected in 2011–2014. RESULTS The estimated prevalence of ASD based on 2014 data was 2.24%, a significant increase from the estimated annualized prevalence of 1.25% based on 2011–2013 data. In contrast, the prevalence of other DD declined significantly from 4.84% based on 2011–2013 data to 3.57% based on 2014 data. The prevalence of ID did not significantly change from 2011–2013 (1.27%) to 2014 (1.10%). The prevalence of having any of the three conditions was constant across survey years. CONCLUSIONS The revised question ordering and new approach to asking about developmental disabilities in the 2014 NHIS likely affected the prevalence estimates of these conditions. In previous years, it is likely that some parents of children diagnosed with ASD reported this developmental disability as other DD instead of, or in addition to, ASD. Following these changes, the 2014 ASD estimate was more similar to ASD prevalence estimates from other sources.
