Linking a History of Childhood Abuse to Adult Health among Canadians: A Structural Equation Modelling Analysis

Early Life Interventions: Impact on Aging and Longevity

Across mammals, lifespans vary remarkably, spanning over a hundredfold difference. Comparative studies consistently reveal a strong inverse relationship between developmental pace and lifespan, hinting at the potential for early-life interventions (ELIs) to influence aging and lifespan trajectories. Focusing on postnatal interventions in mice, this review explores how ELIs influence development, lifespan, and the underlying mechanisms. Previous ELI studies have employed a diverse array of approaches, including dietary modifications, manipulations of the somatotropic axis, and various chemical treatments. Notably, these interventions have demonstrated significant impacts on aging and lifespan in mice. The underlying mechanisms likely involve pathways related to mitochondrial function, mTOR and AMPK signaling, cellular senescence, and epigenetic alterations. Interestingly, ELI studies may serve as valuable models for investigating the complex regulatory mechanisms of development and aging, particularly regarding the interplay among somatic growth, sexual maturation, and lifespan. In addition, prior research has highlighted the intricacies of experimental design and data interpretation. Factors such as timing, sex-specific effects, administration methods, and animal husbandry practices must be carefully considered to ensure the reliability and reproducibility of results, as well as rigorous interpretation. Addressing these factors is essential for advancing our understanding of how development, aging, and lifespan are regulated, potentially opening avenues for interventions that promote healthy aging.

Early-Life Factors and Multimorbidity Risk Later in Older Age: Evidence Based on CHARLS

INTRODUCTION

Early-life factors were reported to exert influence on the health condition of individuals in the long-term. However, limited research explored the connection between early-life factors and multimorbidity in later years.

METHODS

We utilized the data from the China Health and Retirement Longitudinal Study to assess this possible association in the present cross-sectional study. Multimorbidity was determined based on 14 common chronic diseases included in the study. Logistic regression was employed to examine the link between early-life factors and subsequent multimorbidity.

RESULTS

Out of 7,578 participants who met the inclusion criteria for analysis, 3,765 (49.68%) were females. The mean age was 68.25 ± 6.70 years. Participants who rated their health during childhood as average (odds ratio [OR] 0.78, 95% confidence interval [CI] 0.63-0.96) or better [OR 0.72, 95% CI 0.57-0.91] were significantly less likely to experience multimorbidity in older life. By contrast, experiencing violence from two of the family members was significantly associated with future multimorbidity (OR [95% CI], 1.29 [1.04-1.60]). A superior family financial situation was also negatively associated with multimorbidity, with average (OR [95% CI], 0.72 [0.63-0.83]) and better off than average (OR [95% CI], 0.76 [0.62-0.93]).

DISCUSSION

Individuals with poor health status, inferior family socioeconomic status, or experienced violence from family members in childhood were more likely to suffer from multimorbidity in later life. Enhanced social monitoring of potentially adverse conditions in youngsters and targeted interventions could help mitigate the progression of multimorbidity in later life.

Physical, sexual, and psychosocial health impacts of child abuse: Evidence from Ghana

Child abuse is a significant global health problem. While data on child abuse in Ghana are scant, anecdotal evidence suggests the vast majority of Ghanaian children have experienced some form of physical or sexual abuse. This paper explores links between early childhood abuse and health outcomes using a life course perspective. Nationally representative cross-sectional data were collected from a sample of 2289 ever-married Ghanaian women in 2017. Women provided retrospective accounts of different types of violence in early childhood. Random-effects logit models were used to examine the impact of two dimensions of early childhood abuse (physical and sexual) on the physical, sexual, and psychosocial health outcomes of women in later years. Women who experienced childhood physical abuse, but not often, were significantly more likely to report physical disabilities in later years than women who did not experience it. Women reporting childhood sexual abuse were more likely to be depressed in later years than those who never experienced such abuse. They were also significantly more likely to report sexually transmitted diseases. Our findings provide support for the life course theory by showing abuse experienced in childhood could have a long-term impact. We therefore suggest the need for early interventions to address child abuse.

Health and Well-Being Consequences for Gender Violence Survivors from Isolating Gender Violence

Recent scientific literature has published about the Isolating Gender Violence (IGV), the violence exerted by harassers against those who support their victims. IGV provokes suffering to advocates with health and well-being consequences that have been analyzed by more recent research; but IGV provokes also suffering on the victims of gender violence when they see the suffering of those who have supported them and also for their isolation. Thus, the aim of the present study is to explore the health and well-being consequences of IGV on gender violence survivors. The methodology includes three narratives of gender violence survivors whose advocates supporting them were victimized by IGV. The results show, on the one hand, an increase of the health and well-being effects of gender violence already analyzed by scientific literature; on the other hand, new health and well-being effects appear. All survivors interviewed say that, besides those new consequences for their health, the support of those advocates has decreased the global health effects of the total gender violence they suffered.

Research using population-based administration data integrated with longitudinal data in child protection settings: A systematic review

INTRODUCTION

Over the past decade there has been a marked growth in the use of linked population administrative data for child protection research. This is the first systematic review of studies to report on research design and statistical methods used where population-based administrative data is integrated with longitudinal data in child protection settings.

METHODS

The systematic review was conducted according to Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. The electronic databases Medline (Ovid), PsycINFO, Embase, ERIC, and CINAHL were systematically searched in November 2019 to identify all the relevant studies. The protocol for this review was registered and published with Open Science Framework (Registration DOI: 10.17605/OSF.IO/96PX8).

RESULTS

The review identified 30 studies reporting on child maltreatment, mental health, drug and alcohol abuse and education. The quality of almost all studies was strong, however the studies rated poorly on the reporting of data linkage methods. The statistical analysis methods described failed to take into account mediating factors which may have an indirect effect on the outcomes of interest and there was lack of utilisation of multi-level analysis.

CONCLUSION

We recommend reporting of data linkage processes through following recommended and standardised data linkage processes, which can be achieved through greater co-ordination among data providers and researchers.

Why achieving gender equality is of fundamental importance to improve the health and well-being of future generations: a DOHaD perspective

Despite progress in gender equality, women continue to be disadvantaged compared with men. Worldwide, women are more often confronted with poverty, violence, and mental health problems, and they have less access to food and education. All these factors do not only affect women themselves, but also have a negative impact on the child's early environment and impair its early development, thereby reducing the health and well-being of future generations. Framing gender equality as a women's issue fails to highlight the importance of gender equality for the health and well-being of the next generation. As a scientific community investigating early human development and health, we have failed to fully recognize and underscore the importance of gender equality in achieving the best possible start for every child. If women and men had equal rights and opportunities, their children would be more likely to reach their full potential which would improve the health and well-being of future generations. Our studies and interventions have not fully taken into account the complexity of gender inequality and women's disadvantaged positions in society. We need better insight into the complex adaptive interactions between various societal and human factors contributing to gender inequality and find approaches that take this complexity into account. If we want DOHaD science to have societal impact, we should strive beyond gender equality for gender equity and help women achieve equal rights and opportunities. We need to work with public health professionals, human rights activists, and policymakers to gauge the importance of gender equality. After all, gender equality is not only a fundamental human right, but also a necessary foundation for healthier future generations.

Life satisfaction mediates the association between childhood maltreatment and depressive symptoms: a study in a sample of Brazilian adolescents

OBJECTIVE

To evaluate the interrelationships between childhood maltreatment, life satisfaction (LS), and depressive symptoms, and to investigate LS as a mediating factor in the association between childhood maltreatment and depressive symptoms.

METHODS

The sample consisted of 342 adolescents, aged 11 to 17 years (mean = 13.3, SD = 1.52 years), recruited from a public school in Salvador, Brazil. Participants filled out instruments for the collection of sociodemographic data and evaluation of childhood maltreatment, LS, and depressive symptoms. Structural equation modeling (SEM) was used to evaluate the mediating effect of LS.

RESULTS

We detected significant negative correlations between childhood maltreatment and LS and between LS and depressive symptoms. We observed a significant positive correlation between childhood maltreatment and depressive symptoms. LS partially mediated the association between childhood maltreatment and depressive symptoms, mitigating the impact of maltreatment.

CONCLUSION

LS played an important mediating role in the association between childhood maltreatment and depressive symptoms. Longitudinal studies are recommended to fully elucidate these associations, reinforcing the need for attention and care of this vulnerable population.
