BACKGROUND Low birth weight (Birth weight < 2500 g) is a leading cause of prenatal and neonatal deaths. The early identification of Low birth weight (LBW) neonates is essential for any comprehensive initiative to improve their chance of survival. However, a large proportion of births in developing countries take place at home and birth weight statistics are not available. Therefore, there is a ...

We assessed the heritability of head circumference, an approximation of brain size, in twin-sib families of different ages. Data from the youngest participants were collected a few weeks after birth and from the oldest participants around age 50 years. In nearly all age groups the largest part of the variation in head circumference was explained by genetic differences. Heritability estimates we...

Growth trajectories play a central role in life course epidemiology, often providing fundamental indicators of prenatal or childhood development, as well as an array of potential determinants of adult health outcomes. Statistical methods for the analysis of growth trajectories have been widely studied, but many challenging problems remain. Repeated measurements of length, weight and head circum...

BACKGROUND/AIMS Studies on the association between head circumference (HC) and height or weight have shown variable results. METHODS Using data from the Dutch nationwide survey performed in 1997 (n = 14,500), we calculated correlations for different ages, and fitted a regression model for the estimation of HC. HC versus height charts were created for different age groups. Data from children f...

A knowledge of the normal growth of head circumference and its variations is important in paediatric practice and standards are essential for professionals working with children such as paediatricians and general practitioners. Studies have shown that there are substantial racial and regional differences in head ci rcumference.' Therefore standards from one racial group may not be applicable fo...

Background: Anthropometry is a branch of anatomy. One of the important parts of anthropometry is cephalometry, which is characterized by anatomical dimensions of the head area. The aim of this study was to investigate the relationship between brain volume, weight, and IQ in children. Methods: This descriptive-analytical study was performed on 300 students...

OBJECTIVE To provide an evidence-based update emphasizing the importance of measuring head circumference (HC) in infants, with a focus on microcephaly. QUALITY OF EVIDENCE PubMed and EMBASE (OvidSP) were searched. Search terms used were head circumference and infants and measurement; microcephaly and infants and measurement; idiopathic microcephaly and infants; and congenital microcephaly and...

Material and Methods The 813 infants subjected to measurement during the first week of life were born in the non-paying maternity section of the General Hospital, Kandy, during the four months from June to September 1965. Those infants with neonatal pathological conditions, such as hydrocephaly (1 case) and prematurity (28 cases), were not omitted. Infants with clinically recognizable moulding,...

OBJECTIVES To investigate risks of physical activity at work by pregnancy trimester, including the effects on head and abdominal circumference. METHOD At 34 weeks of gestation we interviewed 1327 mothers from the prospective Southampton Women's Survey (SWS); we asked about their activities (working hours, standing/walking, kneeling/squatting, trunk bending, lifting and night shifts) in jobs h...
