title: Birth patterns: are the Chinese in Guangzhou City different?
abstract: Diurnal birth patterns in the City of Guangzhou, China and the City of Calgary in Canada were compared. Chinese data were abstracted from the labor room log book of one large general hospital located in the Hai Zhu district of Guangzhou. Calgary birth data were abstracted from birth notification forms submitted to Calgary Health Services. Information included day of birth, time of delivery, type of delivery and parity. Calgary births are concentrated on Tuesdays to Fridays whereas in Guangzhou weekly patterns varied tremendously according to whether it was assisted or unassisted. Calgary births are below average at night and during evening shift. The time of birth in Guangzhou varied substantially with above average rates for non-assisted births noted at 0800-2400 h, and above average rates for assisted births noted at 0800-1700 h. Differences in hour of birth appeared to be related to obstetric intervention practices. Knowledge of birthing patterns are useful for effective hospital management.
