Genetic Control of Size at Birth

2005
Size at birth is a heritable trait: estimates vary between 30% and 70%, but associations may be confounded by interactions with the maternal-uterine environment. Maternal smoking, length of gestation and parity could confound overall estimates of birth weight inheritance.

Infant size and relative placental weight at birth

Early Human Development, 1980
In 811 unselected term infants, the ratios of placental weight to (a) body weight, (b) head circumference and (c) body length were assessed as possible determinants of infant size at birth. Unlike the placentofetal weight ratio, the ratio of placental weight to either head circumference of body length proved an excellent predictor of infant size ...

Size at Birth, Obesity and Blood Pressure at Age Five

Metabolic Syndrome and Related Disorders, 2007
The fetal origins hypothesis indicates that morphometric evidence of fetal nutritional deprivation is predictive of excessive weight gain/obesity, insulin resistance, and cardiovascular disease after birth. However, it is unclear whether these effects are present in offspring with "normal" birth weights in contemporary Western society, whether they are

Second-trimester placental volume and infant size at birth

Obstetrics & Gynecology, 2001
To investigate the ability of second-trimester placental volume measured sonographically to predict birth size.A total of 712 women were recruited from the antenatal clinic of the University Hospital of the West Indies; 561 fulfilled the study criteria and progressed to delivery.

Small size at birth and later diabetic pregnancy

Obstetrics & Gynecology, 1998
To determine whether small size at birth was associated with an increased risk of diabetes in pregnancy.Linked birth cohorts were evaluated: that of women born at 37-44 weeks' gestation in 1974, and that of their offspring born 1995-1996, at which time birth certificate data included a checkbox for maternal diabetes.

Repeated antenatal corticosteroids: Size at birth and subsequent development

American Journal of Obstetrics and Gynecology, 1999
The objective was to study the effects of repeated antenatal corticosteroids on birth size, growth, and development in preterm infants.This observational study followed up for 3 years a prospective geographic cohort in the state of Western Australia of 477 singleton infants born at

Size‐at‐Birth Standards for a Melanesian Population

Asia-Oceania Journal of Obstetrics and Gynaecology, 1988
AbstractBy sampling all singleton births occurring to clinic‐attending Nivanuatu over an 18‐month period, the percentile distributions of the newborn infant's weight, length and head and chest circumferences were determined. The mean values for males and females respectively were: birth weight 3,162 and 3,085 g, crown‐heel length 50.6 and 50.1 cm, head

Determinants of size at birth in a Canadian population

American Journal of Obstetrics and Gynecology, 1984
Anthropometric, medical, and sociodemographic characteristics and smoking habit of a random sample of postpartum women in a Canadian population were determined. These characteristics were analyzed in relation to the birth size of their babies. With controls for gestational age and fetal sex, the following maternal variables were positively correlated ...

Organochlorine Exposures During Pregnancy and Infant Size at Birth

Epidemiology, 2007
Organochlorines, including polychlorinated biphenyls (PCBs) and pesticides, are environmentally persistent contaminants that concentrate in the food chain as well in human adipose tissue and readily cross the placenta.To follow up on studies suggesting an association of organochlorine exposure with reduced birth size, we investigated the association of

Size at birth and carotid atherosclerosis in later life

Atherosclerosis, 2002
Several studies have shown that low birthweight is associated with a higher risk of stroke and coronary heart disease in later life. Increased atherogenesis may be one underlying mechanism, but few studies have examined this directly. We used duplex ultrasonography to assess the extra-cranial carotid arteries of 389 elderly men and women born and still
