OBJECTIVE To assess whether lesbian mothers of 17-year-old adolescents conceived through donor insemination are satisfied with their choice of a known, open-identity, or unknown sperm donor and whether the mothers' satisfaction is associated with psychological health problems in the index adolescent offspring. DESIGN Mixed-method study. SETTING Not applicable. PATIENT(S) One hundred twent...
OBJECTIVE The aim of the present study was to evaluate the association of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) with anthropometry in the offspring from birth to 12 months old in Tianjin, China. METHODS Between 2009 and 2011, health care records of 38,539 pregnant women had been collected, and their children had been measured body weight and length at b...
STUDY OBJECTIVE Understanding causes of variation in birth weight has been limited by lack of sufficient sets of data that include paternal birth weight. The objective was to estimate risks of low birth weight dependent on parental birth weights and to estimate father-mother-offspring correlations for birth weight to explain the variability in birth weight in terms of effects of genes and envir...
BACKGROUND This study aims to investigate the relationship between birthweight and psychological function, as evaluated by the results of a psychological conscript interview and assessment in young males, including an evaluation of stress susceptibility. METHODS We performed a retrospective cohort study based on linked birth registry data and data from an assessment of psychological function ...
The purpose of this retrospective study was to examine the effect of methylmercury pollution on the sex ratio of offspring at birth and of fetuses at stillbirth in Minamata City, Japan, in the 1950s when severe and widespread methylmercury pollution was experienced. In 4 of 5 years from 1955 to 1959 when methylmercury pollution was most severe, lower numbers of male offspring at birth were obse...
Classic theories on the evolution of senescence make the simplifying assumption that all offspring are of equal quality, so that demographic senescence only manifests through declining rates of survival or fecundity. However, there is now evidence that, in addition to declining rates of survival and fecundity, many organisms are subject to age-related declines in the quality of offspring produc...
Epidemiological evidence suggests that low birth weight is associated with an increased risk of cardiovascular, metabolic and neuroendocrine disorders in adult life. Glucocorticoid administration during pregnancy reduces offspring birth weight and alters the maturation of the lung and other organs. We hypothesised that prenatal exposure to excess glucocorticoids or stress might represent a mech...
Vitamin D deficiency in pregnancy may be associated with increased offspring adiposity, but evidence from human studies is inconclusive. We examined associations between prenatal vitamin D intake, 25-hydroxyvitamin D (25(OH)D) in cord blood, and offspring size and body composition at birth and 5 months. Participants included 605 mother-offspring dyads from the Healthy Start study, an ongoing, p...
BACKGROUND Recent studies have suggested that the birth order effect in allergy may be established during the prenatal period and that the protective effect may originate in the mother. HLA class II disparity between mother and foetus has been associated with significantly increased Th1 production. In this study, we investigated whether production of HLA antibodies 4 years after pregnancy with ...
BACKGROUND Mice models suggest epigenetic inheritance induced by parental allergic disease activity. However, we know little of how parental disease activity before conception influences offspring's asthma and allergy in humans. OBJECTIVE We aimed to assess the associations of parental asthma severity, bronchial hyperresponsiveness (BHR), and total and specific IgEs, measured before conceptio...
