CONTEXT Substantial concern surrounds the potential health effects of the anthrax vaccine, particularly the potential adverse effects on reproductive processes. OBJECTIVE To determine whether receipt of anthrax vaccination by reproductive-aged women has an effect on pregnancy rates. DESIGN, SETTING, AND PATIENTS Cohort study, based on information from a computer database, of women aged 17 t...

The purpose of this study was to investigate the impact of income inequality and parental socioeconomic status on several birth outcomes in Japan. Data were collected on birth outcomes and parental socioeconomic status by questionnaire from Japanese parents nationwide (n = 41,499) and then linked to Gini coefficients at the prefectural level in 2001. In multilevel analysis, z scores of birth we...

OBJECTIVE To investigate whether a short interpregnancy interval is a risk factor for preterm birth in Emirati women, where there is a wide range of interpregnancy intervals and uniformity in potentially confounding factors. METHODS A case-control design based on medical records was used. A case was defined as a healthy multiparous Emirati woman delivering a healthy singleton spontaneously be...

BACKGROUND Infants of immigrant women in Western nations generally have lower birth weights than infants of native-born women. Whether this difference is physiologic or pathological is unclear. We determined whether the use of birth-weight curves tailored to maternal world region of origin would discriminate adverse neonatal and obstetric outcomes more accurately than a single birth-weight curv...

OBJECTIVE To examine the relation between birth weight and measured intelligence at age 7 years in children within the normal range of birth weight and in siblings. DESIGN Cohort study of siblings of the same sex. SETTING 12 cities in the United States. SUBJECTS 3484 children of 1683 mothers in a birth cohort study during the years 1959 through 1966. The sample was restricted to children ...

BACKGROUND We investigate patterns of neurodevelopmental trajectories in infants, using a representative population, and identify risk factors that predict delayed growth. METHODS Participating infants (n = 952; 82.8% of the total sample) were assessed by Mullen Scales of Early Learning at seven time points, from 1 month to 24 months of age. Mothers were recruited in early pregnancy and data ...

The objective of the study discussed in this article was to evaluate the impact of residential proximity to toxic release sites (TRS) and potential implications for low birth weight (LBW) and premature delivery in Shelby County, Tennessee women. The sample (N = 369) included pregnant women who participated in the Blues Project (2007-2009). ArcGIS was used to map the mother's residence at delive...

Research has suggested that trihalomethane exposures during pregnancy might impair fetal growth. Most epidemiologic studies, however, relied on relatively crude exposure assessment methods and did not examine racial/ethnic subgroups. During 1999-2001, vital records data were obtained for a large, racially diverse population residing in 27 Massachusetts communities that received drinking water f...

1. Fertility is an important fitness component, but is difficult to measure in slowly reproducing, long-lived animals such as chimpanzees (Pan troglodytes). 2. We measured fertility and the effect of measured covariates on fertility in a 43-year sample of birth intervals of chimpanzees from the Gombe National Park, Tanzania using Cox proportional hazards regression with individual-level random ...

UNLABELLED There is insufficient evidence on optimal neonatal feeding intervals, with a wide range of practices. The stomach capacity could determine feeding frequency. A literature search was conducted for studies reporting volumes or dimensions of stomach capacity before or after birth. Six articles were found, suggesting a stomach capacity of 20 mL at birth. CONCLUSION A stomach capacity o...
