The aim of this study was to evaluate the effect of prenatal exposure to lead, cadmium and mercury levels on the secondary sex ratio. Whole blood samples were collected from pregnant women enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) study at a median gestational age of 11 weeks and were analyzed for lead, cadmium and mercury. Regression analysis was used to identify...

OBJECTIVES To determine the feasibility and preliminary impact of an electronic health (eHealth) screening, brief intervention and referral to treatment (SBIRT) delivered in primary care to help parents prevent childhood obesity. METHODS Parents of children (5-17 years) were recruited from a primary care clinic. Children's measured height and weight were entered into the SBIRT on a study-desi...

background and aims. early childhood caries (ecc) is a public health problem with biological, social and behavioural determinants and the notion that the principal etiology is inappropriate feeding modalities is no longer tenable. hence this study was undertaken to assess the relationship between ecc and socio-demographic factors, dietary habits, oral hygiene habits and parental characteristics...

Differences in biological responses to exposure to hazardous airborne substances between children and adults have been reported, suggesting children to be more susceptible. Aim of this study was to improve our understanding of differences in susceptibility in cancer risk associated with air pollution by comparing genome-wide gene expression profiles in peripheral blood of children and their par...

Hybrids were produced by crossing female Caspian kutum Rutilus frisii kutum with male grass carp Ctenopharyngodon idella. The genome of eight larvae and parents were studied using microsatellite markers for genetic evaluation and verification. After DNA extraction from parent fish and progeny, hybrid heritability of two loci was assessed using two pairs of microsatellite primers. Hybridizie...

We examined the importance of adult children’s ties with biological parents and stepparents for well-being in adulthood. particularly focused on situations which children are not close new partner their parent, stepparent. Following balance theory, it is straining to be an unbalanced pattern (i.e., stepparent). Firstly, we studied how many adults parent only (dissonance), both stepparent (posit...

BACKGROUND Thalassemia Major Disease is not only assumed as a health disorder, but also a social- economic problem in many countries. The costs of transport and preparation of drugs is considered as the greatest problems for more than 63.8% of the patients' families. This study was conducted by aiming at describing biological experience among parents of patients with Thalassemia Major. METHOD...

Using data from three waves of the National Survey of Families and Households (N=1,963), we examine associations between adolescent family experiences and young adult well-being across a range of indicators, including schooling, substance use, and family-related transitions. We compare children living with both biological parents, but whose parents differ in how often they argue, to children in...

Genetic and environmental influence on risk of premature death in adulthood was investigated by estimating the associations in total and cause-specific mortality of adult Danish adoptees and their biological and adoptive parents. Among all 14,425 non-familial adoptions formally granted in Denmark during the period 1924 through 1947, we selected the study population according to a case-cohort sa...
