To explore this further a case register was set up in Liverpool. Analysis of all new cases that occurred in Liverpool and adjacent parts of Knowsley and Sefton during 1976-81 showed a steep gradient with social class, ranging from 7.7\/100 000 children in the higher classes to 26.3\/100 000 in social class V. The inner city of Liverpool, which has been shown to be underprivileged, had the highest yearly incidence of the disease ever reported--21.1 cases\/100 000 children aged 14 years and under. The associations with poverty support the hypothesis that undernutrition is a causative factor in the disease.<\/jats:p>","DOI":"10.1136\/bmj.287.6407.1757","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T11:00:59Z","timestamp":1238670059000},"page":"1757-1759","source":"Crossref","is-referenced-by-count":62,"title":["Perthes' disease of the hip in Liverpool."],"prefix":"10.1136","volume":"287","author":[{"given":"A J","family":"Hall","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D J","family":"Barker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P H","family":"Dangerfield","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J F","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1983,12,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"478","DOI":"10.1302\/0301-620X.60B4.711792","article-title":"Perthes' disease of the hip in three regions of England","volume":"60","author":"Barker, D.J.P.; Dixon, E.; Taylor, J.F.","year":"1978","unstructured":"Barker DJP, Dixon E, Taylor JF.
