This is a prevalence study of chronic illness and disability in Jordan
ian children 0-7 years of age living in Sweileh, a suburb of Amman. Th
e study was performed in 1991. A total number of 2528 children were ex
amined, representing more than 95% of the children 0-7 years in the ca
tchment area. Of these, 198 (7.8%) had a disability or a chronic disea
se. Fifty-eight children (2.6%) were classified as moderately or sever
ely affected. Boys were in the majority. Compared with the findings in
European and American studies, congenital eye diseases and severe men
tal retardation were common while atopic diseases were rare. Consangui
nity seemed to be important in the aetiology of chronic diseases. Soci
al background factors did not have a substantial impact on the overall
prevalence, but psychomotor delay and a sequel to an injury were more
common in children from poor families.
