title: [Variations in perinatal mortality according to the hour of birth in Switzerland].
abstract: In Switzerland like in most developed countries, the number of births is strongly related to the hour of the day and the day of the week: this pattern is very probably related to the current practice in obstetrics. Less expected is the fact that the perinatal mortality shows a striking circadian rhythm according to the hour of birth. The paper presents this pattern and comments some related issues.
