OBJECTIVE: Growth curves can be used to assess intrauterine growth, to predict diseases in newborns, and to characterize different populations. The objective of this study was to obtain intrauterine growth curves of newborns from the maternity ward of the Hospital Albert Einstein (MAE) and compare them with intrauterine growth curves of a population from California, USA. METHODS: We plotted the...

OBJECTIVES To compare the distribution of body mass index (BMI) in a national representative study in The Netherlands in 1996-7 with that from a study in 1980. METHODS Cross sectional data on height, weight, and demographics of 14 500 boys and girls of Dutch origin, aged 0-21 years, were collected from 1996 to 1997. BMI references were derived using the LMS method. The 90th, 50th, and 10th BM...

The authors investigated variations in cognitive ability by gestational age among 13,824 children at age 6.5 years who were born at term with normal weight, using data from a prospective cohort recruited in 1996-1997 in Belarus. The mean differences in the Wechsler Abbreviated Scales of Intelligence were examined by gestational age in completed weeks and by fetal growth after controlling for ma...

The concentrations of total free amino acids, ammonia and protein in sweat of 44 children, 20 males, and 24 females, 6 to 8 years old, were determined. The children were divided into three groups according to their height, weight, and body weight/height ratio; group I children had heights and weights below the 10th percentile for their age, group II had heights and weights between the 10th and ...

BACKGROUND The relationship between maternal and placental hemodynamic disorders and fetal growth is well known, but few studies have evaluated a link between maternal extracellular water (EW) and newborn birth weight. OBJECTIVE To identify the characteristics of body composition (BC) of women with small for gestational age (SGA) newborns, and to determine the relationship between maternal EW...

OBJECTIVES Lipoprotein(a) consists of an LDL-particle attached to apolipoprotein(a), which is made by the liver. Diterpenes present in boiled coffee raise serum levels of LDL cholesterol and of the liver enzyme alanine aminotransferase in man. We investigated the association between intake of boiled coffee and serum levels of lipoprotein(a). DESIGN, SETTING AND SUBJECTS Healthy Norwegians 40-...

The wage of the 90th (richest) percentile of the wage distribution in Chile increased faster than the median wage and the wage of the 10th percentile between 1975 and 1990. By contrast, from 1990 onwards the wage of the 10th percentile and the median wage grew faster than the 90th percentile. This is one of many findings showing that wage inequality in Chile has been falling, first slowly, then...

BACKGROUND Particulate air pollution has been consistently linked to increased risk of arterial cardiovascular disease. Few data on air pollution exposure and risk of venous thrombosis are available. We investigated whether living near major traffic roads increases the risk of deep vein thrombosis (DVT), using distance from roads as a proxy for traffic exposure. METHODS AND RESULTS From 1995 ...

Preterm Birth: Introduction Low birthweight defines neonates who are born too small, and preterm or premature birth are the terms used to define neonates who are born too early. With respect to gestational age, a newborn may be preterm, term, or postterm. With respect to size, a newborn may be normally grown or appropriate for gestational age, small in size or small-for-gestational age, or over...

Conditional means regression, including ordinary least squares (OLS), provides an incomplete picture of exposure-response relationships particularly if the primary interest resides in the tail ends of the distribution of the outcome. Quantile regression (QR) offers an alternative methodological approach in which the influence of independent covariates on the outcome can be specified at any loca...
