Background: The timing of maternal weight change in pregnancy may be an important determinant of birth weight. The objective of this study was to measure weight gain patterns from early pregnancy until delivery, and to examine the relationship between prenatal weight gain and low birth weight. Methods: A total of 500 pregnant women within 15-20 days of conception, with confirmed pregnancies and...

anthropometric parameters are an important indicator of health and nutritional status comprising the whole span of mans life. however, they are not of the same degree of simplicity and sensitivity in assessing the public health status. during recent decades many studies have attempted to examine the relationships of these measurements in order to present simple alternatives for similar purposes...

this experiment was conducted to evaluate the effects of different levels of dried lemon pulp (dlp) on performance, carcass traits, blood biochemical and immunity parameters of broilers. in this experiment 240 of broilers (ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days. experimental diets included: 1) ...

abstract the effect of weight and force is one of the most important factors to organize and perform reaction time (rt) tasks. the elderly are involved in this variable when they gain weight. the present study was designed to examine the effect of limb weight gain on premotor and motor components of simple and discriminative reaction time in young and elderly men. subjects (16 young and 16 elde...

background: maternal nutrition during pregnancy affects the birth weight of neonates. some of the undesirable pregnancy outcomes are linked to lower birth weights. this study aimed to assess the relationship between maternal dietary patterns, weight gain during pregnancy and nitric oxide (no), as an endothelial relaxing factor, and the possible effects on birth weight.materials and methods: at ...
