Often spatiotemporal resolution/scale of environmental and health data do not align. Therefore, researchers compute exposure by interpolation or by aggregating data to coarse spatiotemporal scales. The latter is often preferred because of sparse geographic coverage of environmental monitoring, as interpolation method cannot reliably compute exposure using the small sample of sparse data points....

BACKGROUND Major improvements are required in the coverage and quality of essential childhood interventions to achieve Millennium Development Goal Four (MDG 4). Long distance to health facilities is one of the known barriers to access. We investigated the effect of networked and Euclidean distances from home to formal health facilities on childhood mortality in rural Tanzania between 2005 and 2...

OBJECTIVE To determine the dimensions and depth of the right internal jugular vein (RIJV) in low birth weight newborns by ultrasound and assess the differences in weight and determine the relationship of the vein with the carotid artery. METHOD We performed a vascular assessment of the RIJV in 100 low birth weight newborns. The subjects were divided into three groups, low birth weight (LBW) n...

phototherapy is a conventional method of lowering serum bilirubin in newborn jaundice. we evaluated the short distance in relation to conventional long distance phototherapy between the light-source and the skin surface. healthy jaundiced neonates undergoing phototherapy were randomized into two groups. the distance between the light-source and the newborn's skin was 20 and 40 centimeters (g20;...

Two experiments are described whose aim was to investigate whether perception of size at birth is determined solely by proximal (retinal) stimulation, or whether newborn babies have the ability to perceive an object's real size across changes in distance. In Experiment 1, preferential looking between pairs of stimuli which varied in real size and viewing distance was found to be solely determin...

BACKGROUND Neonate with abnormal weight is at risk of increased mortality and morbidity. Many factors affect pregnancy outcome. Because of the importance and vital role in birth weight, in this study, some of the factors associated with birth weight in a sample of Iranians neonates were investigated. MATERIALS AND METHODS In this cross-sectional study, 245 newborns in a sample of Iranians neo...

to have an, idea about the relation between the length of birth interval and lactation, and birth control program this study have been done. the material for such analysis was nomad women's fertility history that was in their reproductive period (15-44). the material itself was gathered through a health survey. the main sample was composed of 2,165 qualified women, of whom 49 due to previous or...

BACKGROUND: Infant mortality has traditionally been analyzed as a function of birth weight and birth weight-specific mortality. Often, however, when comparing two populations, the population with higher overall mortality has lower mortality at low birth weights and a reversed pattern at higher birth weights. Methods standardizing birth weight, such as the "relative birth weight", have been prop...
