in this research a comparative study has been made between case and control groups. the cases were low birth weight newborns (under 2500 gr) and the controls were normal berth weighing 2500 gr or more at birth. four groups of birth weight were considered as follows: very low birth weight, low birth weight, moderately low birth weight and normal. the data were collected over a period of 8 months...

Newborns, and especially premature newborns, are at significant risk for developing hypotension in the first week or two after birth. The etiology of hypotension in the newborn may vary, but the very low birth weight and extremely low birth weight preterm infants are less likely to respond to conventional cardiovascular support when they develop hypotension. This article reviews the least conve...

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...

PURPOSE We hypothesized that intended pregnancy is associated with decreased risk of poor birth outcomes, irrespective of age or race. METHODS We conducted a cross-sectional study of 47,956 live singleton births using 1993-2001 data from the Centers for Disease Control and Prevention's (CDC) Pregnancy Risk Assessment Monitoring System (PRAMS). We used logistic regression to estimate the odds ...

PURPOSE To study the association between maternal smoking during pregnancy and low birth weight (LBW), small-for-gestational-age birth weight (SGA) and preterm birth, and to quantify the population-attributable fractions for these outcomes in Switzerland. METHODS Data were gathered for all births in the Canton of Vaud (Switzerland) over a twelvemonth period in 1993-1994. LBW was defined as bi...

BACKGROUND This study aimed to assess the incidence and survival rates of neonates weighing less than 2500g for duration of the first 28 days in an Iranian community. METHODS In this prospective longitudinal study, all neonates with birth weight less than 2500g were selected from the list of all neonates born in the only public-sector referral hospital, for a six months period. The weight of ...

Objectives. To assess the risk of very low birth weight (VLBW) and extremely low birth weight (ELBW) attributable to second trimester amniocentesis. Methods. Records of 4,877 consecutive amniocentesis, performed between 1997 and 2003, were analyzed. Only VLBW and ELBW in the study population (exposed) and in the control group (unexposed) were evaluated. Comparisons were made between the amnioce...

abstractbackground: the survival rate of preterm and low-birth-weight (lbw) infants depends on various factors such as birth weight, gestational age, and quality of care. the present study aimed at evaluating the survival rate of preterm and lbw infants, predictive factors, and the risk of mortality in three training hospitals of mashhad and tabriz cities.methods: this prospective, cohort study...
