background: admission of low birth-weight (lbw) neonates in neonatal intensive care unit (nicu) causes their deprivation of tactile and sensory stimulation. objective: the purpose of this study was to evaluate efficacy of body massage on growth parameters (weight, height and head circumference) gain velocity of lbw in yazd, iran. materials and methods: a randomized clinical trial study was cond...

a selection program is being implemented to improve meat production in makooei sheep. increasing litter size per ewe is the main objective, but possible repercussions on weight traits of lambs should be considered. the aim of this study was to estimate heritability along with genetic and phenotypic correlations between ewe's reproductive vs. weight traits in makooei ewes. data were comprised of...

low birth weight ( lbw, birth weight<2500g) is a significant health problem of children. many studies have made it apparent that there is a direct relationship between low birth weight and infant motality. one of the most important measurements to prevent children morbidity is growth monitoring and the present study was set up to compare the growth indexes of 2 year old children born with low w...

in the present study conducted at a tertiary care level during the period from 2000-2009, the proportion of birth weight (≥2.5 kg) of new born babies was 80.8%, low birth weight (<2.5 kg) of new born babies was 19.2%. of the new born babies, proportion of very low birth weight (<2 kg) was 6.9%. in this study, sex wise difference in the proportion of low birth weight new born babies was not sign...

In developing countries, low birth weight (BW < 2500 grams) accounts for 60% 80% of neonatal deaths. Early identification and referral of LBW babies for extra essential newborn care is vital in preventing neonatal deaths. Studies carried out in different populations have suggested that the use of newborn anthropometric surrogates of birth weight may be a simple and reliable method to identify L...
