background: although several studies have investigated the association between maternal exposure to air pollution and preterm birth, the results are inconsistent. the aim of this study was to further investigate the relation between maternal exposure to ambient air pollution during pregnancy and the risk of preterm birth and low birth weight (lbw) in an iranian pregnant population. materials an...

Introduction Preterm birth is still a major health problem throughout the world. Preterm birth results in 75% of neonatal mortality. We sought to identify risk factors which cause preterm birth. Materials and Methods This cross-sectional study assessed all preterm neonates born in Asali Hospital in Khorram Abad (either by NVD or C/S) during the first 6 months of 2007. Sampling method was censu...

conclusions pregnancies complicated by rls are at increased risk for preterm birth. the improved sleep health of pregnant women could decrease pregnancy complications. results rls complicated 43.7 percent of pregnancies. sleepiness (ess score > 8) was reported in 36.4% of the subjects with preterm birth and 35.9% of the term group. no significant correlation was found between the ess score and ...

abstract background: to compare pregnancy outcomes in women at risk for cervical incompetence after elective versus ultrasound- indicated cerclage. methods: in a prospective randomized tlial, singleton pregnancies with at least one previous spontaneous midtrimester loss or early preterm delivery (between 15 and 32 weeks' gestation) who met clinical crite1ia for the diagnosis of cervical in...

background: preterm birth is the major cause of neonatal mortality and morbidity. objective: the aim of this study was to evaluate the effect of prophylactic vaginal progesterone on decreasing preterm birth rate and neonatal complications in a high-risk population. materials and methods: a randomized, double-blind, placebo-controlled study was performed on 100 high-risk singleton pregnancies. v...

This study investigated the relation between self-reported vaginal bleeding during pregnancy and preterm birth in a prospective cohort of 2,829 pregnant women enrolled from prenatal clinics between 1995 and 2000 in central North Carolina. The overall association between vaginal bleeding and preterm birth was modest (risk ratio (RR) = 1.3, 95% confidence interval (CI): 1.1, 1.6). Bleeding in the...

Reductions in births to teens and preterm birth rates are two recent public health successes in the United States (1,2). From 2007 to 2014, the birth rate for females aged 15-19 years declined 42%, from 41.5 to 24.2 per 1,000 females. The preterm birth rate decreased 8.4%, from 10.41% to 9.54% of live births (1). Rates of preterm births vary by maternal age, being higher among the youngest and ...

background: the incomplete maturation of brain in preterm children results in long-term neurodevelopmental impairment. this study aimed to investigate the static balance function in children with a history of preterm birth. methods: participants were 31 preterm children including 21 moderately preterm (mpt), 10 very preterm (vpt), and 20 term children aged 5.5 and 6.5 years. the cervical vestib...

background :preterm birth is a significant global health problem with serious short- and long-term consequences. this study examined the long term effects of preterm birth on vestibular evoked myogenic potentials (vemps) among preschool-aged children.   methods : thirty-one children with preterm and 20 children with term birth histories aged 5.5 to 6.5 years were studied. each child underwent v...

background: since preterm delivery is an important problem in obstetrics, it is necessary to know the risk factors. periodontal disease is an infectious disease and infection is risk factor for preterm delivery. respecting to the mechanisms of preterm delivery and because involved mediators in this procedure are synthesized in periodontal disease, gum disease is investigated as risk factor for ...
