BACKGROUND The mechanisms underlying the association between maternal age (both young and older maternal age) and adverse perinatal outcomes are unclear. METHODS We examined the association of maternal age at first birth with preterm birth (<37 weeks gestation) and small for gestational age (SGA) in a cohort of 264 695 Danish women, each of which had at least one sister in the cohort (n = 121...
BACKGROUND Little is known about how optimism/pessimism and health-related quality of life compare across cultures. METHODS Three samples of pregnant women in their final trimester were recruited from China, Ghana, and the United States (U.S.). Participants completed a survey that included the Life Orientation Test - Revised (LOT-R, an optimism/pessimism measure), the Short Form 12 (SF-12, a ...
This study established the emergence of stable individual differences in neurobehavioral functioning prior to birth and examined their relation to subsequent infant temperament. Fetal heart rate and movement were recorded longitudinally for 31 fetuses at 6 gestational ages beginning at 20 weeks' gestation. Maternally reported temperament data were collected at 3 and 6 months. Moderate stability...
BACKGROUND While it is well established that very preterm birth (gestational age at birth <32 weeks) is related to increased attention problems, there is still considerable uncertainty of the effects of moderate or late preterm birth or smallness for gestational age (SGA) on attention regulation. AIMS To investigate the impact of gestational age at birth and SGA, birth on child attention prob...
OBJECTIVE To investigate the influence of perinatal risk factors, especially hypotension, on neuromotor status at term in surviving preterm infants born before 32 weeks of gestation. METHODS This study is part of the Leiden Follow-Up Project on Prematurity: a prospective, regional study of 266 live born infants with a gestational age (GA) < 32 weeks born in 1996-1997. Twenty-eight infants die...
19 small for gestational age (SGA) infants with gestational ages less than or equal to 32 weeks were matched with 19 appropriate for gestational age (AGA) preterm neonates with similar risk factors for intraventricular haemorrhage and hyaline membrane disease. Gestational age, 1- and 5-minute Apgar scores, type of delivery, survival rate, use of corticosteroids before delivery, sex, twinning, p...
Gestational weight gain is known to influence fetal growth. However, it is unclear whether the associations between gestational weight gain and fetal growth vary by trimester. In a diverse cohort of 8,977 women who delivered a singleton between 2011 and 2013, we evaluated the associations between trimester-specific gestational weight gain and infant size for gestational age. Gestational weight ...
