Stress and behavioral risk among young expectant couples

Few studies have explored stress and coping among adolescents who are expecting a baby. In particular, young men's experiences during pregnancy have largely been ignored, despite the fact that a young man's experiences and behaviors carry implications for his own, his partner's and his child's health. This study examined the association between maternal and paternal experiences of stress during pregnancy with one's own and one's partner's health behaviors and depressive symptoms among 294 young expectant couples in the U.S. Multilevel modeling showed that one's own experiences of stress were associated with more unhealthy behaviors and more depressive symptoms among both expectant mothers and fathers. Paternal experiences of stress were predictive of more maternal conduct problems, while maternal experiences of stress were predictive of more paternal depressive symptoms and less paternal substance use. These findings highlight the importance of social relationships in affecting health behaviors and mental health among expectant adolescents.

Paternal programming of breast cancer risk in daughters in a rat model: opposing effects of animal- and plant-based high-fat diets.

BackgroundAlthough males contribute half of the embryo’s genome, only recently has interest begun to be directed toward the potential impact of paternal experiences on the health of offspring. While there is evidence that paternal malnutrition may increase offspring susceptibility to metabolic diseases, the influence of paternal factors on a daughter’s breast cancer risk has been examined in few studies.MethodsMale Sprague-Dawley rats were fed, before and during puberty, either a lard-based (high in saturated fats) or a corn oil-based (high in n-6 polyunsaturated fats) high-fat diet (60 % of fat-derived energy). Control animals were fed an AIN-93G control diet (16 % of fat-derived energy). Their 50-day-old female offspring fed only a commercial diet were subjected to the classical model of mammary carcinogenesis based on 7,12-dimethylbenz[a]anthracene initiation, and mammary tumor development was evaluated. Sperm cells and mammary gland tissue were subjected to cellular and molecular analysis.ResultsCompared with female offspring of control diet-fed male rats, offspring of lard-fed male rats did not differ in tumor latency, growth, or multiplicity. However, female offspring of lard-fed male rats had increased elongation of the mammary epithelial tree, number of terminal end buds, and tumor incidence compared with both female offspring of control diet-fed and corn oil-fed male rats. Compared with female offspring of control diet-fed male rats, female offspring of corn oil-fed male rats showed decreased tumor growth but no difference regarding tumor incidence, latency, or multiplicity. Additionally, female offspring of corn oil-fed male rats had longer tumor latency as well as decreased tumor growth and multiplicity compared with female offspring of lard-fed male rats. Paternal consumption of animal- or plant-based high-fat diets elicited opposing effects, with lard rich in saturated fatty acids increasing breast cancer risk in offspring and corn oil rich in n-6 polyunsaturated fatty acids decreasing it. These effects could be linked to alterations in microRNA expression in fathers’ sperm and their daughters’ mammary glands, and to modifications in breast cancer-related protein expression in this tissue.ConclusionsOur findings highlight the importance of paternal nutrition in affecting future generations’ risk of developing breast cancer.Electronic supplementary materialThe online version of this article (doi:10.1186/s13058-016-0729-x) contains supplementary material, which is available to authorized users.

'You have to be a jack of all trades': Fathers parenting their adolescent with chronic pain.

Adolescent chronic pain has an extensive impact on parents, with research typically focused on exploring maternal experiences. This exploratory study sought to identify the specific experiences of six UK fathers who parent an adolescent with chronic pain. Data from semi-structured interviews were analysed using interpretative phenomenological analysis. Paternal experiences were characterised by four themes: 'helplessness', 'containment', 'balance' and 're-evaluation'. Findings highlighted paternal efforts to manage the impact of adolescent chronic pain by focusing inwardly on the family and adopting multiple roles. Fathers identified ways in which they could renegotiate their relationship with their adolescent to manage pain-related disruption.

Paternal age and diet: The contributions of a father’s experience to susceptibility for post-concussion symptomology

In an attempt to improve current understanding of risk factors that influence individual susceptibility to poor outcomes following mild traumatic brain injury (mTBI) or concussion, this project investigated whether modifications to paternal experiences (Advanced Age (AA) or High-Fat Diet (HFD)) affected offspring susceptibility to behavioral symptomology and changes in gene expression following pediatric concussion in a rodent model. The study demonstrated that paternal treatment prior to conception altered behavioral outcomes and molecular characterization of offspring. Offspring of AA fathers demonstrated abnormal behavioral performance when compared to offspring of control fathers. Similarly, paternal HFD altered pathophysiological outcomes for offspring, contributing to the heterogeneity in post-concussion syndrome. Additionally, this study provided insight into the mechanisms that mediate non-genetic paternal inheritance. Paternal treatment and the mTBI significantly influenced expression of a majority of the genes under examination in the prefrontal cortex, hippocampus, and nucleus accumbens, with changes being dependent upon sex and the brain region examined. These epigenetic changes may have contributed to the differences in offspring susceptibility to concussion.

A Comparison of Maternal and Paternal Experiences of Becoming Parents of a Very Preterm Infant

ObjectiveTo compare maternal and paternal experiences of very preterm (VPT) birth (gestational age < 32 weeks) and the NICU stay. DesignQualitative study. SettingData collection took place at parents’ homes 3 to 6 months after NICU discharge. ParticipantsTen parental couples participated in the study (20 parents). All VPT infants were healthy, without any neonatal or postnatal complications or injuries. MethodsComputer-assisted content analysis was used to highlight thematic clusters from parents' narratives, which were labeled through qualitative interpretation. ResultsTwo main dimensions (Adjustment Process to Preterm Birth and Parental Role Assumption) and three main thematic clusters (Facing the Unexpected, Learning to Parent, and Finally Back Home) described the parental experience. Mothers focused mostly on the Finally Back Home cluster, which was characterized by moderate levels of adjustment to preterm birth and by awareness of their own maternal roles. Fathers focused mostly on the Learning to Parent cluster, which was characterized by low to moderate levels of adjustment to preterm birth and by a limited assumption of paternal role. ConclusionTo our knowledge, this study is unique in that we compared mothers and fathers who experienced the VPT births of their infants and described their experiences of the NICU stay. We found that the VPT birth experience for parents involves a dynamic adjustment. Differences in maternal and paternal experiences may indicate the need for tailored supportive interventions in the NICU.

Inner-City Fathers of Children Affected by Chronic Illness: A Systematic Scoping Review of Their Experiences

Abstract BACKGROUND: Childhood chronic illness often impacts not just the child but the whole family, particularly the parents. Parents from inner-city backgrounds (defined as low income/socioeconomic status, unemployed, immigrant, refugee, or ethnic minority, and living in an urban area) face additional challenges. Research has traditionally centred on the mother’s role in caring for a child with a chronic illness, but with the increasing role of fathers caring for these children, research has shifted its focus on paternal experience. However, the experiences of inner-city fathers remain largely unknown. OBJECTIVES: This systematic scoping review aims to explore the experiences of fathers of children with disabilities or chronic health conditions from inner city families, using the Double ABCX model as a conceptual framework. DESIGN/METHODS: A systematic scoping review was conducted between November 2014 and January 2015 using the Arksey and O'Malley framework. Seven databases were searched (Medline, PsycInfo, Embase, Web of Science, CINAHL, Scopus, and Social Work Abstracts). Titles and abstracts meeting inclusion and exclusion criteria were included in the full text review for further assessment. Qualifying articles were critically appraised and relevant data were extracted. The Double ABCX model was used to qualitatively evaluate the articles in terms of stressors, resources, perception, coping, and adaptation. RESULTS: 5114 articles were initially identified and 14 articles met the inclusion criteria. Most of the included studies were conducted in the USA. Most articles discussed fathers from low income/SES backgrounds, while others discussed ethnic minority, immigrant/refugee, and unemployed fathers. Fathers' stressors included financial strain and barriers to accessing healthcare. Fathers' resources, or sources of support, ranged from immediate to extended family members, depending on ethnicity. In terms of perceptions, fathers had different approaches to reconciling the care-giver role with cultural gender norms. Inner-city fathers had more desire for information about their children’s health, but some were uncomfortable with asking physicians. Inner-city fathers were more at risk for coping difficulties and used different coping strategies compared to higher income fathers. Inner-city fathers were at higher risk for maladaptation, including depression, PTSD and less acceptance of the child. CONCLUSION: Fathers from inner-city backgrounds caring for their children affected by chronic illnesses and disabilities have unique experiences requiring a comprehensive approach to providing and communicating care to these children and caregivers. Findings from this review can be used to guide pediatricians in advocating for resources to reduce stressors, enhance coping, and promote positive adaptation for inner-city fathers.

Paternal depression during pregnancy and postpartum: An international Delphi study

BackgroundFathers are at risk for depression during a mother's gestation and postpartum. Assessment, detection, and treatment are hampered by the lack of consensus on this issue. The purpose of this study was to reach expert consensus through the Delphi method on the defining factors of depression in peripartum fathers. MethodsPurposive sampling resulted in the surveying of 14 international expert panelists. The study used a modified Delphi approach in which experts participated in two rounds of open-ended and scale questionnaires, followed by two rounds of opportunities to adjust their responses and/or comment on evolving data until consensus was achieved. ResultsExperts responded to 10 questions on terminology, diagnostics, symptomology, risk/protective factors, biological factors, assessment tools/protocol, cost implications, and key stakeholders. Of these 10 questions presented for discussion, the analysis resulted in 197 coded themes. Consensus was met for 119 of the 197 coded responses (60.41%). LimitationsDiversity of opinion within this Delphi Study was excluded for the sake of consensus. Regression to the mean may have occurred after continuous surveying and when evolving results were shared with panelists. Critics of Delphi methodologies have pointed to the issue of small expert samples typically used and the subjectivity of “expert.” ConclusionConsensus identified diagnostic criteria and symptomology that differentiates the paternal experience of peripartum depression. Experts indicated the importance of a father's social context, biological risk factors, limitations of current assessment tools, key stakeholders, and potential financial costs. Stakeholders on this issue would benefit from translating consensus into assessment and treatment.

Parental experiences of racial discrimination and youth racial socialization in two-parent African American families.

Parents experiencing racial discrimination are likely to transmit racial socialization messages to their children to protect them from future injustices. This study was conducted to better understand the role of parents' racial discrimination in their racial socialization practices for 2-parent African American families. Using a sample from the Promoting Strong African American Families (N = 322 couples) program, we examined the effects of experienced discrimination on one's own and one's partner's racial socialization practices with male (n = 154) and female (n = 168) offspring. Multiple-group actor-partner interdependence models showed that racial discrimination was associated with racial socialization practices. In addition, maternal experiences of discrimination had stronger relations to socialization messages relayed to daughters and greater paternal experiences of discrimination had stronger relations to socialization messages given to sons. This study demonstrates variability in how male and female children in African American families are socialized as a result of their parents' experiences with racial discrimination.

Exploration of first-time fathers′ experiences during the child′s first year

Background: The paternal postpartum period is a tremendous transitional time for first-time fathers and so, their unique experiences should be considered. Aim: To explore new fathers' experiences during the child's first year and the factors associated with their experiences. Setting and Design: A descriptive exploratory research conducted among n = 149 new fathers working in private companies in Bengaluru, Karnataka, India recruited by purposive sampling during their first year of paternal postpartum period. Materials and Methods: An individual interview using a four-point structured rating scale consisting of 50 items measuring their experiences during the first year of paternal postpartum period was used to collect data. Statistical Analysis: All statistical analyses were performed by the Statistical Package for the Social Sciences (SPSS) 17 version. An alpha less than 0.05 was considered to be significant in all analyses. Results: The results revealed that the vast majority of the first-time fathers (61.34%) had positive postpartum experiences as compared to 38.66% who reported negative fatherhood experiences. The key concepts related to their experiences were emotional upheaval, changes in lifestyle, pleasant and rejuvenating fatherhood experiences, relationship difficulties with partners, parents, friends, lack of intimacy with spouse, feelings of social isolation, lack of leisure activities and hobbies, difficulties in balancing career and family, ongoing physical problems, and financial constraints. There was no association of their postpartum paternal experiences with sociodemographic factors. Conclusion: Findings from this study suggest the need for realigning health services that have traditionally focused on mothers and children to father friendly services that respect fathers' strengths, experiences, knowledge, relationship, empowerment, and well-being to promote lasting benefits for fathers and their families.

Fatherhood contributes to increased hippocampal spine density and anxiety regulation in California mice.

IntroductionParenting alters the hippocampus, an area of the brain that undergoes significant experience‐induced plasticity and contributes to emotional regulation. While the relationship between maternal care and hippocampal neuroplasticity has been characterized, the extent to which fatherhood alters the structure and function of the hippocampus is far less understood.MethodsHere, we investigated to what extent fatherhood altered anxiety regulation and dendritic morphology of the hippocampus using the highly paternal California mouse (Peromyscus californicus).ResultsFathers spent significantly more time on the open arms of the elevated plus maze, compared to non‐fathers. Total distance traveled in the EPM was not changed by paternal experience, which suggests that the increased time spent on the open arms of the maze indicates decreased anxiety‐like behavior. Fatherhood also increased dendritic spine density of granule cells in the dentate gyrus and basal dendrites of pyramidal cells in area CA1 of the hippocampus.ConclusionsThese findings parallel those observed in maternal rodents, suggesting that the hippocampus of fathers and mothers respond similarly to offspring.

Hormonal stimulation and paternal experience influence responsiveness to infant distress vocalizations by adult male common marmosets, Callithrix jacchus

Parental experience and hormones play a large role in the common marmoset (Callithrix jacchus) father's care of their offspring. We tested the effect of exogenous estradiol or testosterone on the responsiveness of common marmosets to respond to infant distress vocalizations and whether males who haven't become fathers yet (paired males) would have increased responsiveness to infant distress calls with either steroid or whether parental experience is the most important component for the onset of paternal care. Sixteen male marmosets (8 fathers, 8 paired males) received a vehicle, low dose or high dose of estradiol and additional 16 males were tested with testosterone at three doses for their response either to a vocal control or a recording of an infant distress call for 10min. Without steroid stimulation fathers were significantly more likely to respond to the infant distress stimulus than paired males. Low dose estradiol stimulation resulted in a significant increase in fathers' behavioral response towards the infant distress stimulus but not in paired males. Fathers also showed a significant increase in infant responsiveness from the vehicle dose to the estradiol low dose treatment, but not to the estradiol high dose treatment. Testosterone treatment did not show significant differences between infant responsiveness at either dose and between fathers and paired males. We suggest that neither steroid is involved in the onset of paternal care behaviors in the marmoset but that estradiol may be involved in facilitating paternal motivation in experienced fathers.

Paternal and Maternal Transition to Parenthood: The Risk of Postpartum Depression and Parenting Stress.

Transition to parenthood represents an important life event increasing vulnerability to psychological disorders. Postpartum depression and parenting distress are the most common psychological disturbances and a growing scientific evidence suggests that both mothers and fathers are involved in this developmental crisis. This paper aims to explore maternal and paternal experience of transition to parenthood in terms of parenting distress and risk of postpartum depression. Seventy-five couples of first-time parents were invited to compile the Edinburgh Postnatal Depression Scale and the Parenting Stress Index-Short Form in the first month of children life. Study sample reported very high levels of parenting distress and a risk of postpartum depression in 20.8% of mothers and 5.7% of fathers. No significant correlation between parenting distress and the risk of postpartum depression emerged, both in mothers than in fathers group while maternal distress levels are related to paternal one. The first month after partum represents a critical phase of parents life and it could be considered a developmental crisis characterized by anxiety, stress and mood alterations that could have important repercussions on the child psycho-physical development.

Transgenerational Experiences of Childhood Adversities in the Development of Adolescent Borderline Personality Disorder

Introduction Previous research revealed substantial relations between the experience of childhood adversities and the development of borderline personality disorders (BPD) in adulthood. However, research about antecedents of adolescent BPD is still in its beginnings. Moreover, there is an ongoing controversy regarding transgenerational effects of childhood adversities and potential mediators. Objectives We aim to investigate transgenerational effects of parental childhood experiences on the development of adolescent BPD within the next generation. Hereby, we are focusing on the investigation of differential effects of maternal and paternal experiences of childhood adversities on adolescent BPD and on underlying mechanisms. Methods We consecutively recruited 91 female inpatients ( M age = 15.6 years) from the Department of Child and Adolescent Psychiatry, University Hospital Heidelberg, as well as 87 mothers and 59 fathers. Childhood adversities were assessed for parents and adolescents with the German Childhood Experiences of Care and Abuse Questionnaire, adolescent BPD by means of structured clinical interviews (SKID II). Results Our results are in favor of a transgenerational effect of parental childhood adversities on the development of adolescent BPD. This effect turned out to be stronger for paternal than for maternal childhood adversities. Moreover, paternal childhood adversities revealed to be related to experiences of childhood adversities within the next generation. Conclusions Our results underline the importance of taking the family environment into consideration when developing prevention and treatment programs for adolescent BPD.

Paternal epigenetic effects of population density on locust phase-related characteristics associated with heat-shock protein expression.

Many species exhibit transgenerational plasticity by which environmental cues experienced by either parent can be transmitted to their offspring, resulting in phenotypic variants in offspring to match ancestral environments. However, the manner by which paternal experiences affect offspring plasticity through epigenetic inheritance in animals generally remains unclear. In this study, we examined the transgenerational effects of population density on phase-related traits in the migratory locust Locusta migratoria. Using an experimental design that explicitly controls genetic background, we found that the effects of crowd or isolation rearing on phase plasticity could be inherited to the offspring. The isolation of gregarious locusts resulted in reduced weight in offspring eggs and altered morphometric traits in hatchlings, whereas crowding of solitarious locusts exhibited opposite effects. The consequences of density changes were transmitted by both maternal and paternal inheritance, although the expression of paternal effects was not as pronounced as that of maternal effects. Prominent expression of heat-shock proteins (Hsps), such as Hsp90, Hsp70 and Hsp20.6, could be triggered by density changes. Hsps were significantly upregulated upon crowding but downregulated upon isolation. The variation in parental Hsp expression was also transmitted to the offspring, in which the pattern of inheritance was consistent with that of phase characteristics. These results revealed a paternal effect on phase polyphenism and Hsp expression induced by population density, and defined a model system that could be used to study the paternal epigenetic inheritance of environmental changes.

Do Fathers Matter: Influencing Neural Phenotypes Through Non-Genetic Transmission of Paternal Experiences?

AbstractUnderstanding the role of fathers and how paternal experiences actually influence offspring outcomes is a rapidly growing field of research. This Lamarkian mode of inheritance offers offspring an additional mechanism for environmental adaptation that can occur in a single generation, rather than waiting for chance mutations in DNA that may or may not increase an individual’s chances for survival. This review article examines the influences of many paternal experiences including, stress, drugs, and alcohol, along with enrichment, exercise, diet and paternal age, on offspring neural phenotypes. Where possible, there is also discussion of the underlying mechanisms that facilitate the transmission of these experiences to the offspring. Although previous ideologies maintained a small role for fathers (merely as sperm-donors) in the developmental trajectories of the offspring they sired, research now demonstrates that they influence a wide range of outcomes such as drug and alcohol tolerance, susceptibility to mental illness, and patterning of the hypothalamicpituitary- adrenal (HPA) stress response. These novel findings emphasize the complexity and extensive realm of factors that can influence the development of offspring neural phenotypes.

Paternal early experiences influence infant development through non-social mechanisms in Rhesus Macaques

BackgroundEarly experiences influence the developing organism, with lifelong and potentially adaptive consequences. It has recently become clear that the effects of early experiences are not limited to the exposed generation, but can influence physiological and behavioral traits in the next generation. Mechanisms of transgenerational effects of parental early experiences on offspring development are often attributed to prenatal or postnatal parental influence, but recent data suggest that germ-line plasticity may also play a role in the transgenerational effects of early experiences. These non-genetic transgenerational effects are a potentially important developmental and evolutionary force, but the effects of parental experiences on behavior and physiology are not well understood in socially complex primates. In the non-human primate, the rhesus macaque, nursery rearing (NR) is an early life manipulation used for colony management purposes, and involves separating infants from parents early in life. We examined the effects of maternal and paternal early NR on infant rhesus macaque immunity, physiology, and behavior.ResultsWe theorized that differences in behavior or physiology in the absence of parent-offspring social contact would point to biological and perhaps germ-line, rather than social, mechanisms of effect. Thus, all subjects were themselves NR. Male and female infant rhesus macaques (N= 206) were separated from parents and social groups in the first four days of life to undergo NR. These infants differed only in their degree of NR ancestry – whether their dams or sires were themselves NR. At 3-4 months of age, infants underwent a standardized biobehavioral assessment. Factors describing immunity, plasma cortisol, and emotion regulation were generated from these data using factor analysis. Paternal, but not maternal, NR was associated with greater emotionality and higher plasma cortisol, compared with infants born to CONTROL reared fathers.ConclusionsThese data suggest that macaque biobehavioral makeup is strongly influenced by paternal experiences, and via non-social mechanisms.

Behavioral responses to pups in males with different reproductive experiences are associated with changes in central OT, TH and OTR, D1R, D2R mRNA expression in mandarin voles

Male rodents behave differently toward pups because of different sexual and/or paternal experiences; however, the mechanisms underlying these responses are not well understood. Using socially monogamous mandarin voles (Microtus mandarinus) we investigated the behavioral responses of males with different reproductive experiences (virgin males, paired males and new fathers) to new born pups. Central levels of neuropeptide oxytocin (OT), tyrosine hydroxylase (TH), as well as oxytocin receptor (OTR), dopamine 1-type receptor (D1R) and dopamine 2-type receptor (D2R) mRNA expression in the nucleus accumbens and medial amygdala were also measured in these males. Our data showed that new fathers exhibited more approaching behavior and contained more OT-immunoreactive and TH-immunoreactive neurons. In addition to increased OTR mRNA expression in the nucleus accumbens and medial amygdala, new fathers had higher D1R and D2R mRNA expression in the nucleus accumbens, and less D1R and D2R mRNA expression in the medial amygdala than paired males. These results demonstrate that males with different reproductive experiences display different behavioral responses to pups and that these differences are associated with altered OT and dopamine, and their receptors in specific brain regions.

Au nom du père? Rethinking the History of Fatherhood in Quebec

This article presents a reading of the literature on North American fatherhood as a category of gendered historical experience and as an area of inquiry within masculinity studies. The main focus is on Quebec, where the scholarship in this area has developed more slowly than in English Canada or the United States. The discussion is framed around three key questions: (1) Does the literature suggest that American and Canadian fathers shared in common understandings of their paternal identities in the twentieth century?; (2) Was French-speaking, Catholic Quebec thoroughly distinct in this area or were there common North American ideologies of fatherhood in which Quebecers participated?; and (3) Do Quebec historians of masculinity and fatherhood continue to write in a theoretically impoverished way (Vacante 2005a, 2006) or can we discern the beginnings of a more sophisticated approach that situates the paternal experience within the power dynamics of patriarchy?

Differences in placentophagia in relation to reproductive status in the california mouse (Peromyscus californicus)

Parturient females ingest placenta in most mammalian species, whereas fathers may do so in species in which both parents provide care for their offspring. To determine if the propensity to eat placenta varies with reproductive status in the biparental California mouse, we presented placenta to virgin (housed with a same-sex pairmate), expectant (pregnant with their first litter), and multiparous adult males and females. Liver was presented identically, 3-7 days later, as a control. Multiparous females were more likely to eat placenta than expectant and virgin females (p-values <0.016), whereas both multiparous and expectant males had higher incidences of placentophagia than virgins (p-values <0.016). Liver consumption did not differ among groups within either sex. These results suggest that propensity to eat placenta increases with maternal/birthing experience in females, and with paternal experience and/or cohabitation with a pregnant female in males.
