Background & aim: Preterm delivery is one of the most important problems in pregnancy, as it is the primary cause of 75% of prenatal mortality and morbidities. This study aimed to determine the prevalence and risk factors for preterm delivery in Tehran, Iran. Methods:In this cross-sectional study performed in eight random hospitals from five different regions of Tehran (North, South, West, East...
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 ...
Introduction Preterm birth is defined as delivery before 37 completed weeks (WHO). The issue of preterm birth is still a major health problem in the world; 75% of neonatal mortalities are due to prematurity.(1,3) A variety of morbidities are significantly increased in preterm neonates who survive. Morbidity in multiple organs such as respiratory tract, cardiovascular, GI, metabolic, neurologica...
conclusions: the increased survival of preterm infants was not associated with lower complications. there is now increasing evidence of sustained adverse outcomes into school age and adolescence, for preterm infants. results: cerebral palsy especially spastic diplegia, intellectual disability, visual (retinopathy of prematurity) and hearing impairments are the main neurodevelopmental disorders ...
Women who deliver preterm (<37 completed weeks' gestation) are at high risk for recurrence. This has prompted exploration of candidate genes (both maternal and fetal) associated with preterm delivery. Epidemiologists can use recurrence patterns of preterm delivery across generations to assess the relative contributions of maternal and fetal genes. The authors used data from the Medical Birth Re...
BACKGROUND Preterm birth and other pregnancy complications have been linked to maternal stress during pregnancy. We investigated the association between maternal exposure to severe life events and risk of preterm birth. METHODS Mothers of all singleton live births (n = 1.35 million births) in Denmark between 1 January 1979 and 31 December 2002 were linked to data on their children, parents, s...
This paper is the first in a three-part series on preterm birth, which is the leading cause of perinatal morbidity and mortality in developed countries. Infants are born preterm at less than 37 weeks' gestational age after: (1) spontaneous labour with intact membranes, (2) preterm premature rupture of the membranes (PPROM), and (3) labour induction or caesarean delivery for maternal or fetal in...
aims : understanding the experiences of mothers could be as a strategy for the physicians, nurses who are working in nicu and administrators in the care centers in order to provide supports for parents, particularly mothers and an effective step to improve the quality of nursing care of premature infants and their parents. methods : in this study, one of the qualitative research methods as de...
background: group b streptococcus is regarded as a potential factor for adverse outcomes of pregnancy such as preterm birth. objective: to study the association of maternal vaginal colonization with group b streptococcus (gbs) and preterm labor. materials and methods: from april 2005 to may 2006, vaginal culture for gbs were conducted in 101 laboring women with a gestational age of 24-37 weeks ...
Risk factors for preterm delivery have been described, but whether risk factors differ in the context of prior preterm delivery history is less understood. We assessed whether known risk factors were different in women with versus without prior preterm delivery using medical records of the first and second singleton deliveries in 25,820 Utah women (2002-2010). Longitudinal transition models wit...
