Objectives:

1. To compare the demographic and perinatal characteristics of a group of children with CDH to those of a control group.

2. To determine whether the outcome and prognosis are related to the timing of the diagnostic physical screening examination.

Methods: 231 children born in the years 1994-1995 in the Hadera sub-district: 77 children suspected clinically of having CDH, and 154 controls. All the study children were referred to a pediatric orthopedic surgeon and underwent imaging procedures. The control group was selected systematically �C 2 controls per study patient.

Results: Female gender, firstborn child, and breech presentation at birth were all features that were significantly more common in the study group compared to the controls (odds ratio 4.3, 2.7, 6 respectively) (p <0.05).

If the diagnosis was made after 6 weeks of age there was a higher risk (although not statistically significant) of the patient subsequently requiring surgical treatment (O.R. 3), and of there being motor disability or handicap (O.R. = 2.6).

Conclusions:

1. Children with CDH have certain demographic and perinatal markers.

Early detection of this condition may lessen the need for surgical intervention and the risk of disability or motor handicap.
