Daylight Saving Time and Spontaneous Deliveries: A Case-Control Study in Italy.

(1) Background: Although the current literature shows that daylight saving time (DST) may play a role in human health and behavior, this topic has been poorly investigated with reference to Obstetrics. The aim of this case-control study was to evaluate whether DST may influence the number of spontaneous deliveries. (2) Methods: A low-risk pregnancy cohort with spontaneous onset of labor ( = 7415) was analyzed from a single Italian region for the period 2016-2018.
