BACKGROUND IVF children, including singletons, are known to have a poorer obstetric outcome than children born after spontaneous conception. With a broad introduction of single embryo transfer (SET), this scenario might change. This study compares the obstetric outcome after IVF with SET, elective SET (eSET), non elective SET (non-eSET) and double embryo transfer (DET) with outcomes in the gene...

The aim of the study was to investigate the frequency of and the predictors for rehospitalization in preterm infants into early childhood, focusing on gender differences. All preterm infants born at <32 weeks of gestation in North Tyrol between January 2003 and December 2005 were enrolled in this survey. About one fifth of all children were readmitted, showing an inverse downward trend with inc...

Background and Objective: Sensory processing patterns refer to a person’s ability to receive and respond to sensory events which are important to succeed in daily routine activities. This study aims to determine the sensory processing patterns in infants/toddlers. Methods: This is a cross-sectional study. A total of 518 infants/toddlers participated in this study. Their ages ranged from birth...

School-age children born preterm are particularly at risk for low mathematical achievement, associated with reduced working memory and number skills. Early identification of preterm children at risk for future impairments using brain markers might assist in referral for early intervention. This study aimed to examine the use of neonatal magnetic resonance imaging measures derived from automated...

OBJECTIVES To assess the distribution of height, weight, and head circumference (HC) in preterm infants for ages 0-4 years, by gestational age (GA) and sex, and to construct growth reference charts for preterm-born children, again by GA and sex, for monitoring growth in clinical practice. STUDY DESIGN The community-based cohort study covered a quarter of The Netherlands. 1690 preterm infants ...

OBJECTIVE Although preterm very low birth weight infants have a high prevalence of neuroanatomical abnormalities when evaluated at term-equivalent age, patterns of brain growth in prematurely born infants during school age and adolescence remain largely unknown. Our goal was to test the hypothesis that preterm birth results in long-term dynamic changes in the developing brain. METHODS We perf...

OBJECTIVE Our purpose was to identify factors associated with the physical activity in young children. STUDY DESIGN Participants were 214 children (aged 3-5 years) enrolled in 10 childcare centers who were monitored for physical activity with an accelerometer during 2 continuous days (48 hours). Mean daily activity counts, activity counts between 9 AM and 5 PM, and percentage of time spent in...

OBJECTIVE Compare respiratory health in children born extremely preterm (EP) or with extremely low birthweight (ELBW) nearly one decade apart, hypothesizing that better perinatal management has led to better outcome. DESIGN Fifty-seven (93%) of 61 eligible 11-year old children born in Western Norway in 1999-2000 with gestational age (GA) <28 weeks or birthweight <1000 gram (EP1999-2000) and m...

AIM The aim of the study was to assess the influence of decreasing gestational age on the risk of developmental delay in various domains at age 4 years among children born at a wide range of gestational ages. METHOD In a community-based cohort, the parents of 1439 preterm-born children (24 0/7 to 35 6/7 wks) and 544 term-born children (38 0/7 to 41 6/7 wks') born in 2002 and 2003 completed th...

Identification of maternal environmental factors influencing preterm birth risks is important to understand the reasons for the increase in prematurity since 1990. Here, we utilized a health survey, the US National Health and Nutrition Examination Survey (NHANES) to search for personal environmental factors associated with preterm birth. 201 urine and blood markers of environmental factors, suc...
