A survey of 282 young adults, mentally handicapped on an administrative definition, was undertaken in th London Boroughs of Hounslow, Hammersmith, and Ealing between October 1978 and April 1980. The prevalence of mental handicap in the age group born between 1958 and 1963 was calculated, and variations were shown between the three boroughs and within the borough of Ealing. The findings suggested that the prevalence of severe mental handicap in this area is not markedly different from rates found in other British studies, but the administrative prevalence is inflated because numbers of mildly handicapped school leavers subsequently use the services for the mentally handicapped. Subjects were classified according to behavioural disabilities: young people in residential care were more likely to be severely incontinent, not literate, and without speech, but overall there was no relationship between degree of disability and placement in residential care.
1978年10月至1980年4月期间，在伦敦希灵登区、哈默史密斯区和伊灵区对282名行政定义上的智障青年进行了调查。计算了1958年至1963年出生年龄组的智力障碍患病率，并显示了三个区之间以及伊灵区内的差异。研究结果表明，该地区重度智力障碍的患病率与英国其他研究的结果没有明显差异，但行政上的患病率被夸大了，因为轻度智障的离校生随后会使用智障人士服务。根据行为障碍对受试者进行分类：住在寄宿机构的年轻人更有可能出现严重失禁、不识字和不会说话的情况，但总体而言，残疾程度与寄宿机构安置之间没有关系。
