Pregnancy Duration and Birth

Pregnancy Duration and Birth assesses the duration of the pregnancy from conception to birth, and the labor process, e.g., were the children born on time, prematurely or late; time between birth of the children; manner of birth (e.g., vaginal, cesarean), position of the children in the uterus before birth; and the course of the delivery.

In NTR projects YC_DSC and YC_ADHMRI, pregnancy duration and birth were assessed via mother-ratings obtained via a telephone interview.
