OBJECTIVES This study aims to identify birth weight variation according to maternal characteristics and gestational weight gain. METHODS It is a cross-sectional descriptive study with 433 puerperal women (> or = 20 years old) who attended a public maternity hospital in Rio de Janeiro. The data were collected through interviews with the women and access to their medical records. Several models...

AIM To study the relation between fetal growth and markers of collagen metabolism and insulin-like growth factor binding protein-1 (IGFBP-1) in term infants. METHODS Cord vein plasma was obtained from 67 term infants of gestational age 37.1-41.7 weeks (39 appropriate for gestational age (AGA), 11 large for gestational age (LGA; relative birth weight >/= 2.0 SD), and 17 small for gestational a...

OBJECTIVE Population-based data in the United States on trends in cerebral palsy (CP) birth prevalence are limited. The objective of this study was to examine trends in the birth prevalence of congenital spastic CP by birth weight, gestational age, and race/ethnicity in a heterogeneous US metropolitan area. METHODS Children with CP were identified by a population-based surveillance system for...

OBJECTIVE To evaluate the impact of cotinine-confirmed smoking reduction during pregnancy on infant birth weight and gestational age at birth. DESIGN Group analyses from a prospective, randomized smoking-cessation intervention trial using cotinine levels to assess smoking cessation and reduction. SETTING Four maternity clinics of Jefferson County Health Department in Birmingham, Ala. PATI...

BACKGROUND Recent studies have demonstrated that low and high birth-weight at birth are risk factors of developing diabetes. The aim of this study was to determine if the abnormal birth-weight is related with hyperinsulinemia and elevated index of the Homeostasis Model assessment for Insulin Resistance (HOMA-IR) at birth, in at term newborns. METHODS Newborns with gestational age between 38 a...

OBJECTIVE The accuracy of a population-based sex ratio at birth (SRB) in China has long been questioned. To depict a more accurate profile, the present study used data from a national surveillance system for health facility births to explore the characteristics of SRB in China. METHODS Data from China's National Maternal Near Miss Surveillance System between 2012 and 2015 were used. We restri...

BACKGROUND Singleton pregnancy with a live birth beyond 37 weeks of gestation is the ultimate goal of any assisted reproductive technology. However, singletons conceived after ART are found to have a poor perinatal outcome in comparison to naturally conceived singletons. It was hypothesized that the outcome of singleton conceived after transfer of two or more embryos may be dependent on the sha...

BACKGROUND Preterm infants are at a higher risk of hospitalisation following discharge from the hospital after birth. The reasons for rehospitalisation and the association with gestational age are not well understood. METHODS This was a retrospective birth cohort study of all live, singleton infants born in Western Australia between 1st January 1980 and 31st December 2010, followed to 18 year...

SETTING Tertiary university-affiliated medical center. PATIENT(S) 242 children born after PGD, 242 children born after intracytoplasmic sperm injection (ICSI) (158 singletons and 42 twins pairs in each group), and 733 children born after...
