STUDY QUESTION: Do paternal exposures to folic acid deficient (FD), and/or folic acid supplemented (FS) diets, throughout germ cell development adversely affect male germ cells and consequently offspring health outcomes? SUMMARY ANSWER: Male mice exposed over their lifetimes to both FD and FS diets showed decreased sperm counts and altered imprinted gene methylation with evidence of transmission of adverse effects to the offspring, including increased postnatal-preweaning mortality and variability in imprinted gene methylation...

The purpose of this study was to explore resilience processes in Palestinian refugee families living under Israeli occupation for multiple generations. Qualitative methods, critical postcolonial theories, and community-based research approaches were used to examine intergenerational protective practices and to contribute to reconceptualizations of resilience from indigenous perspectives. First, the researcher developed a collaborative partnership with a nongovernmental organization (NGO) in a UN refugee camp in the occupied West Bank...

This study examined parental proximal processes involving in the intergenerational transmission of depressive symptoms from parents to their children. Extant literature has predominantly focused on maternal depressive symptoms. Yet, the mechanisms that may underlie the transmission of paternal depressive symptoms is less often studied. Participants were Chinese parents of first-graders (N = 2282). Results of structural equation modeling suggested that maternal and paternal depressive symptoms may be transmitted to their children through differential processes...

BACKGROUND: The psychological effects of trauma are well-documented among refugee adults and children alone, yet less research has attended to the intergenerational transmission of trauma within refugee families. Additionally, there is considerable diversity between refugee populations as well as within-group variation in the experiences and effects of refugee trauma. OBJECTIVE: The current study examines the longitudinal effects of maternal traumatic distress on family functioning and child mental health outcomes among Southeast Asian refugee women and their adolescent children...

Intergenerational transmission of traumatization (ITT) occurs when traumatized parents have offspring with increased risk for emotional and behavioral problems. Although fetal exposure to the maternal biological milieu is known to be one factor in ITT, PTSD-driven parent-child interactions represent an additional important and potentially modifiable contributor. The Perinatal Interactional Model of ITT presented herein proposes that PTSD leads to social learning and suboptimal parent-child interactions, which undermine child regulatory capacity and increase distress, largely explaining poor social-emotional outcomes for offspring of parents with PTSD...

Decades of research have demonstrated that physical stress (PS) stimulates bone remodeling and affects bone structure and function through complex mechanotransduction mechanisms. Recent research has laid ground to the hypothesis that mental stress (MS) also influences bone biology, eventually leading to osteoporosis and increased bone fracture risk. These effects are likely exerted by modulation of hypothalamic-pituitary-adrenal axis activity, resulting in an altered release of growth hormones, glucocorticoids and cytokines, as demonstrated in human and animal studies...

There is growing evidence from animal and human studies that demonstrate that acquired paternal traits can impair both a male's fertility and the health of his offspring, including advanced age, smoking, stress, trauma, under-nutrition, infection, toxin exposure, and obesity. Curiously, many of these factors manifest as impaired neurological, behavioural, and/or metabolic functioning in offspring. The underlying molecular mechanisms that respond to the paternal environment and act as vectors of intergenerational transmission are beginning to emerge...

BACKGROUND: Previous studies have proposed that having parents out of work may influence adolescent illness behaviour and school attendance. However, prior research investigating this question has been limited by retrospective reporting and case control studies. In a large epidemiological study we investigated whether parental work absence was associated with symptom complaints and increased school absenteeism in adolescents. METHODS: We analysed data from a large epidemiological study of 10,243 Norwegian adolescents aged 16-19...

Executive functioning (EF) may be transmitted across generations such that strengths or deficiencies in parent EF are similarly manifested in the child. The present study examined the contributions of parent EF and impulsivity on adolescent EF, and investigated whether household chaos is an environmental moderator that alters these transmission processes. American adolescents (N = 167, 47% female, 13-14 years old at Time 1) completed behavioral measures of EF and reported household chaos at Time 1 and one year later at Time 2...

BACKGROUND: Interpersonal stress generation is one mechanism hypothesized to increase risk for the intergenerational transmission of depression. Although there is some evidence of stress generation in offspring of depressed mothers, specific predictors of stress generation in these youth remain unknown. The goal of this study was to examine a peripheral measure of cognitive-affective reactivity (i.e. pupil dilation) to emotional interpersonal stimuli as a predictor of stress generation in offspring of depressed mothers...

Behavioral consequences of prenatal alcohol exposure (PAE) can be transmitted from in utero-exposed F1 generation to their F2 offspring. This type of transmission is modulated by genetic and epigenetic mechanisms. This study investigated the intergenerational consequences of prenatal exposure to a low ethanol dose (1 g/kg) during gestational days 17-20, on ethanol-induced hypnosis in adolescent male F1 and F2 generations, in two strains of rats. Adolescent Long-Evans and Sprague-Dawley male rats were tested for sensitivity to ethanol-induced hypnosis at a 3...

OBJECTIVE: Growing evidence suggests the deleterious consequences of exposure to childhood maltreatment (CM) not only might endure over the exposed individual's lifespan but also might be transmitted across generations. The time windows, mechanisms, and targets of such intergenerational transmission are poorly understood. The prevailing paradigm posits that mother-to-child transmission of the effects of maternal CM likely occurs after her child's birth. The authors seek to extend this paradigm and advance a transdisciplinary framework that integrates the concepts of biological embedding of life experiences and fetal origins of health and disease risk...

Intergenerational adjustment theories suggest that immigrant adolescents may be particularly influential in their families, as they take on family obligations and serve as language brokers. Empirical research in this regard is, however, scarce. One aim of this study was to test whether adolescents' linguistic competence in German adds to the explanation of maternal socio-cultural adaptation difficulties in Germany. Another aim was to investigate whether the association between adolescents' linguistic competence and maternal socio-cultural adaptation difficulties differs depending on adolescents' involvement in family obligations...

Research on attachment transmission has focused on variable-centered analyses, where hypotheses are tested by examining linear associations between variables. The purpose of this study was to apply a relationship-centered approach to data analysis, where adult states of mind, maternal sensitivity, and infant attachment were conceived as being three components of a single, intergenerational relationship. These variables were assessed in 90 adolescent and 99 adult mother-infant dyads when infants were 12 months old...

This research investigates the social reproduction of inequality by drawing on prospective longitudinal data from three generations of Youth Development Study respondents. It examines intergenerational influence on the relatively unexplored academic self-concept as well as educational plans, a critical component of the status attainment model. A structural equation model, based on 422 3-generation triads, finds evidence that the sources giving rise to the development of children's (Generation 3) achievement orientations do not only result from parental (G2) contemporaneous influence...

BACKGROUND: To study the intergenerational transmission of externalizing behaviors. METHODS: Participants came from a community-based random sample of residents in two upstate New York counties (N = 548). Data were collected from mothers at mean age 40 and from their children from adolescence (mean age = 14, SD = 2.8) to early midlife (mean age = 43, SD = 2.8) at seven time points. Structural equation modeling (SEM) was used to study the psychosocial factors as related to externalizing behaviors in early midlife...

PURPOSE: Despite high rates of HIV in areas of Sub-Saharan Africa and men's role in driving the epidemic, little is known about whether or how sexual risk-both behaviors and beliefs-may be passed down through generations of males. This study examined associations between sexual risk behaviors and sex-related beliefs of adolescent males and those of their male caregivers in Kenya, as well as the potential moderating effects of parenting characteristics and father-son relationship quality...

The current study examined intergenerational transmission of trauma in grandchildren of Holocaust survivors. While many typically do not find evidence for such effects, careful reading of the relevant literature suggests conditions under which such effects may be obtained. Following, we made use of three factors. First, we took the number of grandparents exposed to the Holocaust into account. Second, we examined participants who were exposed to present terror and displayed posttraumatic stress disorder (PTSD) symptoms...

Embryonic development is highly sensitive to xenobiotic toxicity and in utero exposure to environmental toxins affects physiological responses of the progeny. In the United States, the prevalence of allergic asthma (AA) is inexplicably rising and in utero exposure to cigarette smoke increases the risk of AA and bronchopulmonary dysplasia (BPD) in children and animal models. We reported that gestational exposure to sidestream cigarette smoke (SS), or secondhand smoke, promoted nicotinic acetylcholine receptor-dependent exacerbation of AA and BPD in mice...
