BACKGROUND The role of social and family environments in the development of mental health problems among children and youth has been widely investigated. However, the degree to which parental working conditions may impact on developmental psychopathology has not been thoroughly studied. METHODS We conducted a case-control study of several mental health outcomes of 19,833 children of sawmill w...

To further elucidate the possible effects of paternal alcohol exposure on fetal and post-natal development, Lee et al. conducted an experimental animal study from which potential transgenerational consequences of paternal alcohol exposure on mouse offspring were explored. The authors concluded that paternal alcohol consumption likely poses some risk to those developing offspring. However, the a...

Within the last few decades our understanding of the importance of non-cognitive skills for socioeconomic success has grown along with our knowledge of the deleterious impacts of paternal incarceration for child wellbeing. Given the importance of early skills and that elementary-aged children constitute the majority of children with incarcerated parents, understanding the connection between pat...

Our study is the first investigation of the effects of advanced paternal age (APA) on the developmental trajectory of social behavior in rodent offspring. Given the strong epidemiological association between APA and sexually dimorphic neurodevelopmental disorders that are characterized by abnormalities in social behavior (autism, schizophrenia), we assessed sociability in male and female inbred...

The present study examined the direct and indirect relationships between parenting processes (parental closeness, parental monitoring, and parental peer approval), low self-control, and aggression. Participants were 546 adolescents aged 14-18 attending state high schools in Turkey. Participants completed a questionnaire that included measures of parenting processes, self-control, and aggression...

Maternal smoking during pregnancy (SDP) is associated with increased risk of externalizing and internalizing behaviors in offspring. Two explanations (not mutually exclusive) for this association are direct causal effects of maternal SDP and the effects of genetic and environmental factors common to parents and offspring which increase smoking as well as problem behaviors. Here, we examined the...

This study investigated the association between Iranian university students' perception of their fathers and their object-relation and defense mechanism. Participants were 438 students between 18-22 years from Allameh Tabatabae University, who agreed to fill the Fatherhood Scale out (Dick, 2004), Bell object relation inventory and defense mechanism style, and defense style questionnaire (DSQ-40...

The aim of this study was to examine the feasibility of using an economic and practical method in order to perform non-invasive prenatal testing of thalassemia as a sing gene disorder.Sixteen (16) pregnant mothers in the 11th week of pregnancy who were referred for prenatal diagnosis of thalassemia were selected. The parents had one of IVSII-1, IVSI-5 or FR codon 8/9 mutations. Enrichment of cf...

Viability relative to Cy/Pm as a standard was studied in Drosophila melanogaster. One experiment, E1, consisted of progeny from eleven distinct 7 x 7 factorial mating designs with reciprocals for second chromosomes extracted from a natural population. The other experiment, E2, consisted of two distinct sets of heterozygotes with reciprocals and corresponding homozygotes. It was established from...

This study exploits twin births to identify the effects of fertility on parental labor supply in rural northwestern China. Instrumental variable estimation suggests that having an additional child reduces mothers’ yearly by seven days and shifts their from wage work (a 10-day reduction) farm three-day increase). In contrast, paternal is unaffected changes fertility.
