Generation, Gestation, and Birth

Reference range of birth weight with gestation and first-trimester prediction of small-for-gestation neonates.

OBJECTIVE Firstly, to establish a reference range of birth weight with gestation at delivery; secondly, to identify maternal characteristics that are significantly associated with birth weight; and thirdly, to determine if combinations of maternal characteristics, fetal nuchal translucency thickness (NT), and serum concentrations of free beta-human chorionic gonadotrophin (β-hCG) and pregnancy-...

Factors Influencing Length of Gestation and Birth Weight in Cattle

Postnatal growth and performance in cattle are influenced to some extent by the course of prenatal development. It is important, therefore, to know what factors affect prenatal development and the degree of variation brought about by these factors. The present study was undertaken as part of a broad project to evaluate the factors that affect the efficiency of feed utilization in cattle. This p...

Chlordecone exposure, length of gestation, and risk of preterm birth.

Persistent organic pollutants have not been conclusively associated with length of gestation or with preterm birth. Chlordecone is an organochlorine pesticide that has been extensively used to control the banana root borer population in the French West Indies. Data from the Timoun Mother-Child Cohort Study conducted in Guadeloupe between 2004 and 2007 were used to examine the associations of ch...

Weight at third birthday related to birth weight, duration of gestation, and birth order.

It is now well recognized that the weight ofchildren during the first few years of life is closely related to their weight at birth. This point has been made by Illingworth in a number of publications (Illingworth, 1939 and 1950; Illingworth, Harvey, and Gin, 1949; Illingworth, Harvey and Jowett, 1950), and has been confirmed recently by Parfit (1951) and by Norval, Kennedy, and Berkson (1951)....
