Obesity and type 2 diabetes risk in midadult life: the role of childhood adversity

Association between adverse childhood experiences and type 2 diabetes mellitus in later life: A case-control study

Adverse childhood experiences (ACEs) are potentially traumatic events that occur before 18 years of age. Studies emphasize the importance of childhood adversity as a risk factor for developing non-communicable diseases, including type-2 diabetes mellitus (T2DM) in adulthood. This case-control study involved 137 patients with T2DM and 134 non-diabetic adults of both genders (mean age 46.9 and 45.7 years, respectively). In addition to collecting socio-demographic, behavioral, and anthropological data, a 10-item ACE scale was utilized to gather information regarding childhood adversities, while perceived stress was assessed using the perceived stress scale-4. Fasting and 2-hour post glucose load blood sugar levels, HbA1c, and fasting lipid profiles were measured. Both univariable and multivariable binary logistic regression analyses were performed to investigate whether ACE is a potential risk factor for T2DM, with a significance level of 0.05. Around two-thirds of T2DM patients reported having ACE scores of 4 or higher, with the mean ACE score significantly higher in the case group than in the control group (3.96 vs. 3.34; p<0.0001). The logistic regression analysis found that T2DM was linked to female gender, hypertension, dyslipidemia, family history of DM, higher perceived stress, and a higher ACE score of 4 and above. After adjusting for confounding factors, individuals with an ACE score of 4 or higher had a significantly greater risk of developing T2DM (OR: 2.24; 95% CI 1.238-4.061). The study revealed a significant association between higher ACE scores and an increased risk of developing T2DM. As a recommendation, further investigation into the epigenetic mechanisms underlying this relationship is warranted.

Early life stress in relation with risk of overweight, depression, and their comorbidity across adulthood: findings from a British birth cohort

BACKGROUND

Multimorbidity, known as the co-occurrence of at least two chronic conditions, has become of increasing concern in the current context of ageing populations, though it affects all ages. Early life risk factors of multimorbidity include adverse childhood experiences (ACEs), particularly associated with psychological conditions and weight problems. Few studies have considered related mechanisms and focus on old age participants. We are interested in estimating, from young adulthood, the risk of overweight-depression comorbidity related to ACEs while adjusting for early life confounders and intermediate variables.

METHODS

We used data from the 1958 National Child Development Study, a prospective birth cohort study (N = 18 558). A four-category outcome (no condition, overweight only, depression only and, overweight-depression comorbidity) was constructed at 23, 33, and 42 years. Multinomial logistic regression models adjusting for intermediate variables co-occurring with this outcome were created. ACEs and sex interaction on comorbidity risk was tested.

RESULTS

In our study sample (N = 7762), we found that ACEs were associated with overweight-depression comorbidity risk throughout adulthood (RRR [95% CI] at 23y = 3.80 [2.10-6.88]) though less overtime. Comorbidity risk was larger than risk of separate conditions. Intermediate variables explained part of the association. After full-adjustment, an association remained (RRR [95% CI] at 23y = 2.00 [1.08-3.72]). Comorbidity risk related to ACEs differed by sex at 42.

CONCLUSION

Our study provides evidence on the link and potential mechanisms between ACEs and the co-occurrence of mental and physical diseases throughout the life-course. We suggest addressing ACEs in intervention strategies and public policies to go beyond single disease prevention.

Determinants of obesity in Latin America

Obesity rates are increasing almost everywhere in the world, although the pace and timing for this increase differ when populations from developed and developing countries are compared. The sharp and more recent increase in obesity rates in many Latin American countries is an example of that and results from regional characteristics that emerge from interactions between multiple factors. Aware of the complexity of enumerating these factors, we highlight eight main determinants (the physical environment, food exposure, economic and political interest, social inequity, limited access to scientific knowledge, culture, contextual behaviour and genetics) and discuss how they impact obesity rates in Latin American countries. We propose that initiatives aimed at understanding obesity and hampering obesity growth in Latin America should involve multidisciplinary, global approaches that consider these determinants to build more effective public policy and strategies, accounting for regional differences and disease complexity at the individual and systemic levels.

Increased Cardiometabolic Risk in Healthy Young Adults With Early Life Stress

OBJECTIVE

This study aimed to evaluate the relationship between early life stress (ELS) and metabolic risk in healthy young adults and assess the role of health behaviors.

METHODS

Young adults aged 18 to 40 years ( N = 190) with no medical conditions or medication usage were recruited from the community. Participants with ELS ( N = 113) had a history of childhood maltreatment, and most also experienced parental loss ( n = 88). Controls ( N = 77) had no history of maltreatment or parental loss. Standardized interviews and self-reports assessed demographics, adversity, medical/psychiatric history, and health behaviors. Blood pressure and anthropometrics were measured, and fasting plasma assayed for lipid profiles, glucose, insulin level, and hemoglobin A 1c . We calculated both a clinical cut-point and continuous composite metabolic risk score based on clinical risk factors and the mean of z scores of each measure, respectively.

RESULTS

ELS was significantly associated with increased clinical cut-point ( β = 0.68, 95% confidence interval [CI] = 0.20-1.17, p = .006) and continuous ( β = 0.23, 95% CI = 0.08-0.038, p = .003) composite metabolic risk scores. On sensitivity analysis, the association of ELS with the continuous composite metabolic risk score was reduced to a trend after adjusting for a range of psychosocial and health predictors ( β = 0.18, 95% CI = 0.00-0.36, p = .053), with both diet and college graduate status significant in the model.

CONCLUSIONS

Healthy young adults with a history of ELS have increased metabolic risk scores as compared with controls. This relationship may be partially due to health behaviors and socioeconomic factors. These findings underline that ELS is an early contributor to metabolic risk.

Exposure to early-life stress impairs weight-loss maintenance success in mice

OBJECTIVE

The impact of early-life stress on weight-loss maintenance is unknown.

METHODS

Mice underwent neonatal maternal separation (NMS) from 0 to 3 weeks and were weaned onto a high-fat sucrose diet (HFSD) from 3 to 20 weeks. Calorie-restricted weight loss on a low-fat sucrose diet (LFSD) occurred over 2 weeks to induce a 20% loss in body weight, which was maintained for 6 weeks. After weight loss, half of the mice received running wheels, and the other half remained sedentary. Mice were then fed ad libitum on an HFSD or LFSD for 10 weeks and were allowed to regain body weight.

RESULTS

NMS mice had greater weight regain, total body weight, and adiposity compared with naïve mice. During the first week of refeeding, NMS mice had increased food intake and were in a greater positive energy balance than naïve mice. Female mice were more susceptible to NMS-induced effects, including increases in adiposity. NMS and naïve females were more susceptible to HFSD-induced weight regain. Exercise was beneficial in the first week of regain in male mice, but, long-term, only those on the LFSD benefited from exercise. As expected, HFSD led to greater weight regain than LFSD.

CONCLUSIONS

Early-life stress increases weight regain in mice.

Association of Childhood Adversity With Frailty and the Mediating Role of Unhealthy Lifestyle: A Lifespan Analysis

OBJECTIVES

Childhood adversity and lifestyle have been associated with frailty in later life, but not much is known about factors that may explain these associations. Therefore, this study aims to investigate the association of childhood adversity with frailty, and the mediating role of unhealthy lifestyle in the association.

METHODS

This lifespan analysis included 152,914 adults aged 40-69 years old from the UK Biobank. We measured childhood adversity with five items: physical neglect, emotional neglect, sexual abuse, physical abuse, and emotional abuse through online mental health survey. Frailty was measured by the frailty index; an unhealthy lifestyle score (range: 0-5) was calculated based on unhealthy body mass index, smoking, alcohol consumption, physical inactivity, and unhealthy diet at the baseline survey. Multiple logistic regression and mediation analysis were performed.

RESULTS

A total of 10,078 participants (6.6%) were defined as having frailty. Participants with any childhood adversity had higher odds of frailty. For example, in the fully adjusted model, with a one-point increase in cumulative score of childhood adversity, the odds of frailty increased by 38% (odds ratio: 1.38; 95% Confidence Interval: 1.36, 1.40). Unhealthy lifestyle partially mediated the associations of childhood adversity with frailty (mediation proportion: 4.4%-7.0%). The mediation proportions were largest for physical (8.2%) and sexual (8.1%) abuse.

CONCLUSIONS

Childhood adversity was positively associated with frailty, and unhealthy lifestyle partially mediated the association. This newly identified pathway highlights the potential of lifestyle intervention strategies among those who experienced childhood adversity (in particular, physical, and sexual abuse) to promote healthy aging.

Health effects associated with exposure to intimate partner violence against women and childhood sexual abuse: a burden of proof study

The health impacts of intimate partner violence against women and childhood sexual abuse are not fully understood. Here we conducted a systematic review by comprehensively searching seven electronic databases for literature on intimate partner violence-associated and childhood sexual abuse-associated health effects. Following the burden of proof methodology, we evaluated the evidence strength linking intimate partner violence and/or childhood sexual abuse to health outcomes supported by at least three studies. Results indicated a moderate association of intimate partner violence with major depressive disorder and with maternal abortion and miscarriage (63% and 35% increased risk, respectively). HIV/AIDS, anxiety disorders and self-harm exhibited weak associations with intimate partner violence. Fifteen outcomes were evaluated for their relationship to childhood sexual abuse, which was shown to be moderately associated with alcohol use disorders and with self-harm (45% and 35% increased risk, respectively). Associations between childhood sexual abuse and 11 additional health outcomes, such as asthma and type 2 diabetes mellitus, were found to be weak. Although our understanding remains limited by data scarcity, these health impacts are larger in magnitude and more extensive than previously reported. Renewed efforts on violence prevention and evidence-based approaches that promote healing and ensure access to care are necessary.

Neighbourhood crime and obesity: Longitudinal evidence from Australia

RATIONALE

Obesity remains a significant public health concern globally with over one billion adults projected to be obese by 2025. To better understand the drivers of obesity and to inform policy, it is important to explore the factors that influence obesity.

OBJECTIVES

The objective of this paper to examine if the crime rates in the neighbourhood or local area in which a person lives influences their likelihood of being obese. Thus, we seek to contribute to the literature on the determinants of obesity by asking the question: what is the effect of neighbourhood (i.e., postcode) crime on obesity? We also examine the pathways through which neighbourhood crime influences obesity with a focus on the role of social capital, physical activity and sleep quality.

METHODS

Using 14 waves of longitudinal data from the Household, Income and Labour Dynamics in Australia (HILDA) survey merged with official police statistics on crime rates at the postcode level, we apply identification strategies that address endogeneity arising from endogenous sorting and omitted variable bias.

RESULTS

We find that an increase in neighbourhood crime rates is associated with an increase in body mass index (BMI) and the likelihood of being obese. Exploring the pathways through which neighbourhood crime influences obesity, we find that social capital and physical activity are important channels, while sleep quality is not. The evidence also suggests that the effects of violent crime are more pronounced compared to property crime.

CONCLUSION

Our findings suggest that targeting crime, and in particular violent crime, which seems to be driving the findings, is a core mechanism for reducing BMI and maintaining healthy body weight. The mediating role of physical activity and social capital also suggest that public policy can specifically target these areas by providing interventions that promote social capital and physical activity even amidst high crime rates.

The development and initial feasibility testing of D-HOMES: a behavioral activation-based intervention for diabetes medication adherence and psychological wellness among people experiencing homelessness

Introduction

Compared to stably housed peers, people experiencing homelessness (PEH) have lower rates of ideal glycemic control, and experience premature morbidity and mortality. High rates of behavioral health comorbidities and trauma add to access barriers driving poor outcomes. Limited evidence guides behavioral approaches to support the needs of PEH with diabetes. Lay coaching models can improve care for low-resource populations with diabetes, yet we found no evidence of programs specifically tailored to the needs of PEH.

Methods

We used a multistep, iterative process following the ORBIT model to develop the Diabetes Homeless Medication Support (D-HOMES) program, a new lifestyle intervention for PEH with type 2 diabetes. We built a community-engaged research team who participated in all of the following steps of treatment development: (1) initial treatment conceptualization drawing from evidence-based programs, (2) qualitative interviews with affected people and multi-disciplinary housing and healthcare providers, and (3) an open trial of D-HOMES to evaluate acceptability (Client Satisfaction Questionnaire, exit interview) and treatment engagement (completion rate of up to 10 offered coaching sessions).

Results

In step (1), the D-HOMES treatment manual drew from existing behavioral activation and lay health coach programs for diabetes as well as clinical resources from Health Care for the Homeless. Step (2) qualitative interviews (n = 26 patients, n = 21 providers) shaped counseling approaches, language and choices regarding interventionists, tools, and resources. PTSD symptoms were reported in 69% of patients. Step (3) trial participants (N = 10) overall found the program acceptable, however, we saw better program satisfaction and treatment engagement among more stably housed people. We developed adapted treatment materials for the target population and refined recruitment/retention strategies and trial procedures sensitive to prevalent discrimination and racism to better retain people of color and those with less stable housing.

Discussion

The research team has used these findings to inform an NIH-funded randomized control pilot trial. We found synergy between community-engaged research and the ORBIT model of behavioral treatment development to develop a new intervention designed for PEH with type 2 diabetes and address health equity gaps in people who have experienced trauma. We conclude that more work and different approaches are needed to address the needs of participants with the least stable housing.

Exposure to early life stress impairs weight loss maintenance success in mice

Early life stress increases obesity risk, but its impact on weight loss maintenance is unknown. Mice underwent neonatal maternal separation (NMS) from 0-3 weeks and were weaned onto high fat sucrose diet (HFSD) from 3-20 weeks. Calorie-restricted weight loss on a low fat sucrose diet (LFSD) occurred over 2 weeks to induce a 20% loss in body weight, which was maintained for 6 weeks. After weight loss, half the mice received running wheels (EX) the other half remained sedentary (SED). Mice were then fed ad libitum on HFSD or LFSD for 10 weeks and allowed to regain body weight. NMS mice had greater weight regain, total body weight and adiposity compared to naïve mice. During the first week of refeeding, NMS mice had increased food intake and were in a greater positive energy balance than naïve mice, but total energy expenditure was not affected by NMS. Female mice were more susceptible to NMS-induced effects, including increases in adiposity. NMS and naïve females were more susceptible to HFSD-induce weight regain. Exercise was beneficial in the first week of regain in male mice, but long-term only those on LFSD benefited from EX. As expected, HFSD led to greater weight regain than LFSD.

Social Determinants of Health and Body Mass Index in American Indian/Alaska Native Children

Objective: To examine the associations between social determinants of health (SDOH) and prevalent overweight/obesity status and change in adiposity status among American Indian and Alaska Native (AI/AN) children. Methods: The study sample includes 23,950 AI/AN children 2-11 years of age, who used Indian Health Service (IHS) from 2010 to 2014. Multivariate generalized linear mixed models were used to examine the following: (1) cross-sectional associations between SDOH and prevalent overweight/obesity status and (2) longitudinal associations between SDOH and change in adiposity status over time. Results: Approximately 49% of children had prevalent overweight/obesity status; 18% had overweight status and 31% had obesity status. Prevalent severe obesity status was 20% in 6-11-year olds. In adjusted cross-sectional models, children living in counties with higher levels of poverty had 28% higher odds of prevalent overweight/obesity status. In adjusted longitudinal models, children 2-5 years old living in counties with more children eligible for free or reduced-priced lunch had 15% lower odds for transitioning from normal-weight status to overweight/obesity status. Conclusions: This work contributes to accumulating knowledge that economic instability, especially poverty, appears to play a large role in overweight/obesity status in AI/AN children. Research, clinical practice, and policy decisions should aim to address and eliminate economic instability in childhood.

Trauma Across the Life Span and Multisystem Morbidity in Women With HIV

OBJECTIVE

Sexual and physical abuse are highly prevalent among women living with HIV (WLWH) and are risk factors for the development of mental health and substance use disorders (MHDs, SUDs), and cognitive and medical comorbidities. We examined empirically derived patterns of trauma, MHD, and SUD, and associations with later cognitive and health outcomes.

METHODS

A total of 1027 WLWH (average age = 48.6 years) in the Women's Interagency HIV Study completed the World Mental Health Composite International Diagnostic Interview from 2010 to 2013 to identify MHDs, SUDs, and age at onset of sexual and physical abuse. Then, cognitive impairment, cardiovascular/metabolic conditions, and HIV disease outcomes were assessed for up to 8.8 years. Latent class analysis identified patterns of co-occurring trauma, MHDs, and/or SUDs. Generalized estimating equations determined associations between these patterns and midlife cognitive and medical outcomes.

RESULTS

Six distinct profiles emerged: no/negligible sexual/physical trauma, MHD, or SUD (39%); preadolescent/adolescent sexual trauma with anxiety and SUD (22%); SUD only (16%); MHD + SUD only (12%); early childhood sexual/physical trauma only (6%); and early childhood sexual/physical trauma with later MHD + SUD (4%). Profiles including early childhood trauma had the largest number of midlife conditions (i.e., cognitive, cardiovascular, HIV-related). Preadolescent/adolescent sexual trauma with anxiety and SUD predicted both global and domain-specific cognitive declines. Only SUD without trauma predicted lower CD4, whereas childhood trauma with MHD + SUD predicted increased CD8.

CONCLUSIONS

WLWH have complex multisystem profiles of abuse, MHD, and/or SUD that predict midlife cognitive, metabolic/cardiovascular, and HIV outcomes. Understanding the interplay between these factors over time can identify risks and personalize preventative and treatment interventions.

Metabolic syndrome among young adults at high and low familial risk for depression

BACKGROUND

Our study examined whether the early-onset depression phenotype among young adults (probands) is associated with the metabolic syndrome (MetS) and its components, and if MetS characterizes unaffected but high-risk siblings of probands.

METHODS

We studied three groups of young adults (Mage = 25 years, s.d. = 3.84 years): probands with histories of childhood onset depression - i.e. early-onset phenotype - (n = 293), their unaffected siblings (high-risk siblings, n = 273), and healthy controls (n = 171). Participants completed a full psychiatric interview, physical and laboratory assessments, and self-rating scales. MetS was defined using the criteria of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults ().

RESULTS

Early-onset depression phenotype and being a high-risk sibling were associated with higher MetS composite scores relative to that of controls, but did not differ from one another. With regard to MetS components: Probands and siblings had similarly larger waist circumference and lower HDL than did controls, while siblings and controls had lower triglyceride levels than did probands but did not differ from one another. Groups did not differ on glucose levels and SBP.

CONCLUSIONS

Our study extends the literature on the association between MetS and depression and underscores the importance of depression phenotypes: failure to account for the clinical heterogeneity of depression may partly underlie the inconsistent findings regarding its relation to MetS. The results also suggest that, in depression-prone populations, MetS may predate and possibly function as a risk factor for eventual depression.

Association of childhood adversity with frailty and the mediating role of unhealthy lifestyle: Findings from the UK biobank

Background

Childhood adversity and lifestyle have been associated with frailty in later life, but not much is known about factors that may explain these associations. An unhealthy lifestyle may play an important role in the pathway from childhood adversity to frailty. Therefore, this study aims to investigate the association of childhood adversity with frailty, and the mediating role of unhealthy lifestyle in the association.

Methods

This lifespan analysis included 152914 adults aged 40-69 years old from the UK Biobank. We measured childhood adversity with five items: physical neglect, emotional neglect, sexual abuse, physical abuse, and emotional abuse through online mental health survey. Frailty was measured by the frailty index; an unhealthy lifestyle score (range: 0-5) was calculated based on unhealthy body mass index, smoking, drinking, physical inactivity, and unhealthy diet at the baseline survey. Multiple logistic regression and mediation analysis were performed.

Results

A total of 10078 participants (6.6%) were defined as having frailty. Participants with any childhood adversity had higher odds of frailty. For example, in the fully adjusted model, with a one-point increase in cumulative score of childhood adversity, the odds of frailty increased by 41% (Odds Ratio: 1.41; 95% Confidence Interval: 1.39, 1.44). Unhealthy lifestyle partially mediated the associations of childhood adversity with frailty (mediation proportion: 4.4%-7.0%). The mediation proportions were largest for physical (8.2%) and sexual (8.1%) abuse.

Conclusions

Among this large sample, childhood adversity was positively associated with frailty, and unhealthy lifestyle partially mediated the association. This newly identified pathway highlights the potential of lifestyle intervention strategies among those who experienced childhood adversity (in particular, physical and sexual abuse) to promote healthy aging.

Racial/Ethnic Differences in Associations Between Traumatic Childhood Experiences and Both Metabolic Syndrome Prevalence and Type 2 Diabetes Risk Among a Cohort of U.S. Women

OBJECTIVE

Childhood adversity has been associated with metabolic syndrome (MetS) and type 2 diabetes risk in adulthood. However, studies have yet to investigate traumatic childhood experiences (TCEs) beyond abuse and neglect (e.g., natural disaster) while considering potential racial/ethnic differences.

RESEARCH DESIGN AND METHODS

To investigate race/ethnicity as a potential modifier of the association between TCEs, MetS, and type 2 diabetes, we used prospectively collected data from 42,173 eligible non-Hispanic White (NHW; 88%), Black/African American (BAA; 7%), and Hispanic/Latina (4%) Sister Study participants (aged 35-74 years) enrolled from 2003 to 2009. A modified Brief Betrayal Trauma Survey captured TCEs. At least three prevalent metabolic abnormalities defined MetS, and self-report of a new diagnosis during the study period defined type 2 diabetes. We used adjusted Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% CIs for type 2 diabetes over a mean ± SD follow-up of 11.1 ± 2.7 years, overall and by race/ethnicity. We also tested for modification and mediation by MetS.

RESULTS

Incident cases of type 2 diabetes were reported (n = 2,479 among NHW, 461 among BAA, and 281 among Latina participants). Reporting any TCEs (50% among NHW, 53% among BAA, and 51% among Latina participants) was associated with a 13% higher risk of type 2 diabetes (HR 1.13; 95% CI 1.04-1.22). Associations were strongest among Latina participants (HR 1.64 [95% CI 1.21-2.22] vs. 1.09 for BAA and NHW). MetS was not a modifier but mediated (indirect effect, HR 1.01 [95% CI 1.00-1.01]; P = 0.02) the overall association.

CONCLUSIONS

TCE and type 2 diabetes associations varied by race/ethnicity and were partially explained by MetS.

Adverse childhood experiences and risk of diabetes: A systematic review and meta-analysis

Background

The association between adverse childhood experiences (ACEs) and diabetes is unclear. This systematic review and meta-analysis aims to quantify the association between the number and types of ACEs and diabetes during adulthood based on available observational studies.

Methods

A comprehensive literature search of studies exploring the association between ACEs and diabetes was conducted in PubMed, Medline, and Embase databases until 15 April 2022. A random-effects model was used to pool odds ratios (ORs) and 95% confidence intervals (CIs) for the number and types of ACEs with diabetes. Regarding the association between the number of ACEs and diabetes, we used funnel plots to examine publication bias, subgroup analysis to explore sources of heterogeneity, and sensitivity analysis to explore the robustness of the pooled results.

Results

A total of 49 studies were included. Individuals with higher continuous ACEs (per each additional ACE: OR = 1.06, 95% CI = 1.02-1.10), any ACE (OR = 1.22, 95% CI = 1.16-1.28), or ≥4 ACEs (OR = 1.44, 95% CI = 1.27-1.63) were at an increased risk of diabetes in adulthood when compared with individuals without ACEs. Across specific ACE types, childhood economic adversity (OR = 1.11, 95% CI = 1.04-1.19), physical abuse (OR = 1.14, 95% CI = 1.07-1.21), sexual abuse (OR = 1.25, 95% CI = 1.12-1.39), verbal abuse (OR = 1.11, 95% CI = 1.03-1.20), and incarceration (OR = 1.22, 95% CI = 1.03-1.45) were associated with diabetes. However, neglect, emotional abuse, domestic violence, parental divorce or separation, parental death, and living with a family member with substance abuse or mental disorders were not significantly associated with diabetes.

Conclusions

Individuals with ACEs may have a cumulative risk for diabetes in adulthood. It is critical to prevent ACEs and build resilience in individuals affected by ACEs.

Associations of abuse and neglect with young adult health in a population-based longitudinal cohort: Findings from Project EAT

Childhood maltreatment (abuse and neglect) is associated with a range of negative outcomes, but a gap remains in understanding of how specific maltreatment types, particularly neglect and non-familial sexual abuse, relate to health and behavior. This study examined the association of neglect and sexual abuse (both familial and non-familial), as well as familial physical and emotional abuse, with: depressive mood and eating disorders; tobacco and marijuana use; and BMI ≥ 25 kg/m2 and BMI ≥ 30 kg/m2 in young adults. Data came from Project EAT (Eating and Activity in Teens and Young Adults), a population-based longitudinal study of weight-related health from adolescence into young adulthood. Maltreatment before age 18 was retrospectively reported at ages 26-33. Risk differences (RDs) and 95% confidence intervals (CIs) were estimated for those with a given maltreatment type to those without, and also for the cumulative number of maltreatment types experienced. One in 3 participants reported abuse or neglect. All maltreatment types were associated with at least one adverse health outcome, with physical abuse being least consistently related to the outcomes. Emotional abuse showed the strongest association with depressive mood. All maltreatment types were associated with eating disorder diagnosis, tobacco use, and marijuana use (except physical abuse for eating disorder). There was little evidence of a maltreatment association with BMI ≥ 25 kg/m2; emotional abuse and neglect were associated with BMI ≥ 30 kg/m2. Prevention of maltreatment needs to be a top public health priority.

Controlling contamination in child maltreatment research: Impact on effect size estimates for child behavior problems measured throughout childhood and adolescence

Contamination, when members of a comparison or control condition are exposed to the event or intervention under scientific investigation, is a methodological phenomenon that downwardly biases the magnitude of effect size estimates. This study tested a novel approach for controlling contamination in observational child maltreatment research. Data from The Longitudinal Studies of Child Abuse and Neglect (LONGSCAN; N = 1354) were obtained to estimate the risk of confirmed child maltreatment on trajectories of internalizing and externalizing behaviors before and after controlling contamination. Baseline models, where contamination was uncontrolled, demonstrated a risk for greater internalizing (b = .29, p < .001, d = .40) and externalizing (b = .14, p = .040, d = .19) behavior trajectories. Final models, where contamination was controlled by separating the comparison condition into subgroups that did or did not self-report maltreatment, also demonstrated risks for greater internalizing (b = .37, p < .001, d = .51) and externalizing (b = .22, p = .028, d = .29) behavior trajectories. However, effect size estimates in final models were 27.5%-52.6% larger compared to baseline models. Controlling contamination in child maltreatment research can strengthen effect size estimates for child behavior problems, aiding future child maltreatment research design and analysis.

Allostatic load and systemic comorbidities in psychiatric disorders

Psychiatric disorders are complex, disabling, and chronic conditions that are often accompanied by one or more systemic medical comorbidities. In this narrative review, we provide an overview of the allostatic load concept, which represents a multi-system dysregulation in response to chronic stress and link it to systemic comorbidities associated with psychiatric disorders. We synthesized published literature gathered using Medline (Ovid), Scopus, and PsychInfo and identified a high frequency of systemic comorbidities for both mood and psychotic disorders. The identified cardiovascular, metabolic, and immune comorbidities may represent the result of chronic wear and tear caused by a complex interaction between chronic psychosocial stress, health risk behaviors, pharmacological stressors, and the biological systems involved in the development of allostatic load. These findings support the notion that psychiatric disorders should be re-conceptualized as systemic disorders, affecting the brain and systemic biological pathways in an interconnected fashion to result in systemic comorbidities. We suggest that the multi-systemic and multi-dimensional approach that drives the allostatic load concept should be considered for understanding comorbidities in vulnerable psychiatric patients.

Association of Exposure to Abuse, Nurture, and Household Organization in Childhood With 4 Cardiovascular Disease Risks Factors Among Participants in the CARDIA Study

Background

We investigated associations of childhood abuse with 4 cardiovascular disease risk factors in adulthood, and whether exposure to nurturing and household organization in childhood mitigated these associations.

Methods and Results

The CARDIA (Coronary Artery Risk Development in Young Adults) study (baseline examination, 1985–1986) was used to examine associations of childhood exposures (measured retrospectively at the year 15 examination) with incident obesity, type 2 diabetes, hypertension, and hyperlipidemia (assessed from baseline to year 30). Race‐ and sex‐stratified Cox proportional hazards models were used to examine associations of exposure to childhood abuse with incident cardiovascular disease risk factors. Interaction terms between exposure to abuse and exposure to nurturing relationship and household organization were included to test for effect modifications. Exposure to occasional/frequent abuse (versus no abuse) was associated with incident type 2 diabetes among White men (hazard ratio [HR], 1.81; 95% CI, 1.06–3.08). Exposure to low versus no abuse was associated with incident hyperlipidemia among White men (HR, 1.35; 95% CI, 1.09–1.67) and White women (HR, 1.26; 95% CI, 1.01–1.56). Risks of incident hyperlipidemia were higher for White women who experienced abuse and lived in dysfunctional households (HR, 3.61; 95% CI, 1.62–8.05) or households with low levels of organization (HR, 2.05; 95% CI, 1.25–3.36) compared with White women who experienced abuse but lived in well‐organized households (HR, 0.66; 95% CI, 0.41–1.06). Similar patterns were seen for Black men who lived in dysfunctional households (HR, 3.62; 95% CI, 1.29–10.12) or households with low organization (HR, 2.01; 95% CI, 1.08–3.72).

Conclusions

We identified race‐ and sex‐specific associations of childhood exposures with incident cardiovascular disease risk factors. The associations of household organization and dysfunction with cardiovascular disease risks merits further investigation.

Early life stress and autonomic response to acute mental stress in individuals with coronary heart disease

Early life stress (ELS) has been associated with an increased risk of cardiovascular disease. We examined whether ELS was associated with autonomic function and stress reactivity among individuals with coronary heart disease (CHD). We included patients with stable CHD from two parallel studies, the Mental Stress Ischemia Prognosis Study (MIPS) and the Myocardial Infarction and Mental Stress Study 2 (MIMS2), and assessed ELS using the Early Trauma Inventory-Self-Report-Short Form. Participants underwent a laboratory-based mental stress task while undergoing ambulatory electrocardiographic monitoring. We used multivariate linear regression models to estimate the associations between ELS and heart rate variability (HRV; low frequency [LF], high frequency [HF], and LF and HF [LH] ratio). The analytic sample included 405 MIPS and 284 MIMS2 participants. Most participants endorsed at least one experience of ELS (92.2%). Although we did not observe associations between ELS and HRV outcomes in the overall sample, ELS was associated with lower LH ratio HRV during recovery in the posttraumatic stress disorder (PTSD) subgroup, ELS x PTSD interaction, p = .041. In the MIMS2 subgroup, ELS was associated with lower resting period LF HRV, B ̂ $ \widehat{B} $  = -0.16 ln ms² ; 95% CI [-0.31, -0.02]. Exposure to physical trauma was associated with decreased HF HRV overall reactivity only among participants with high to moderate depressive symptoms, B ̂ $ \widehat{B} $  = -0.52 ln ms² vs. B ̂ $ \widehat{B} $  = 0.01 ln ms² , p = .013. Overall, heterogeneous associations between ELS and HRV emerged, suggesting the need for additional research regarding longer-term ambulatory HRV.

Developmental alterations of intestinal SGLT1 and GLUT2 induced by early weaning coincides with persistent low-grade metabolic inflammation in female pigs

Early-life adversity (ELA) is linked with the increased risk for inflammatory and metabolic diseases in later life, but the mechanisms remain poorly understood. Intestinal epithelial glucose transporters sodium-glucose-linked transporter 1 (SGLT1) and glucose transporter 2 (GLUT2) are the major route for intestinal glucose uptake but have also received increased attention as modulators of inflammatory and metabolic diseases. Here, we tested the hypothesis that early weaning (EW) in pigs, an established model of ELA, alters the development of epithelial glucose transporters and coincides with elevated markers of metabolic inflammation. The jejunum and ileum of 90-day-old pigs previously exposed to EW (16 days wean age), exhibited reduced SGLT1 activity (by ∼ 30%, P < 0.05) than late weaned (LW, 28 days wean age) controls. In contrast, GLUT2-mediated glucose transport was increased (P = 0.003) in EW pigs than in LW pigs. Reciprocal changes in SGLT1- and GLUT2-mediated transport coincided with transporter protein expression in the intestinal brush-border membranes (BBMs) that were observed at 90 days and 150 days of age. Ileal SGLT1-mediated glucose transport and BBM expression were inhibited by the β-adrenergic receptor (βAR) blocker propranolol in EW and LW pigs. In contrast, propranolol enhanced ileal GLUT2-mediated glucose transport (P = 0.015) and brush-border membrane vesicle (BBMV) abundance (P = 0.035) in LW pigs, but not in EW pigs. Early-weaned pigs exhibited chronically elevated blood glucose and C-reactive protein (CRP) levels, and adipocyte hypertrophy and upregulated adipogenesis-related gene expression in visceral adipose tissue. Altered development of intestinal glucose transporters by EW could underlie the increased risk for later life inflammatory and metabolic diseases.NEW & NOTEWORTHY These studies reveal that early-life adversity in the form of early weaning in pigs causes a developmental shift in intestinal glucose transport from SGLT1 toward GLUT2-mediated transport. Early weaning also induced markers of metabolic inflammation including persistent elevations in blood glucose and the inflammatory marker CRP, along with increased visceral adiposity. Altered intestinal glucose transport might contribute to increased risk for inflammatory and metabolic diseases associated with early-life adversity.

Childhood Maltreatment, Mental Well-Being, and Healthy Lifestyle in Patients With Chronic Thromboembolic Pulmonary Hypertension

Introduction

Chronic thromboembolic pulmonary hypertension (CTEPH) is a potentially life-threatening condition associated with high morbidity and mortality. However, advances in medical, surgical and interventional treatment have markedly improved the outcome of patients with CTEPH. Additional factors potentially influencing quality of life (QoL) and outcome in CTEPH are yet to be defined. Child maltreatment is a major risk factor for unfavorable behavioral, mental as well as physical health outcomes and has been associated with decreased QoL. To date, no study assessed the impact of childhood trauma in patients with CTEPH.

Methods

Patients with CTEPH were invited to complete the Childhood Trauma Questionnaire (CTQ). Data were compared to prevalence data from the German population. Mental well-being was assessed using the Hospital Anxiety and Depression Scale (HADS) and quality of life was measured using the WHO Quality of Life Questionnaire (WHOQOL). Furthermore, lifestyle factors and physical health parameters were studied.Logistic regression analysis was used to investigate a possible impact of child maltreatment on markers of disease severity.

Results

One-hundred and seven patients with CTEPH completed the CTQ. These patients reported higher rates of emotional abuse and physical abuse and emotional neglect compared to the German population while rates of physical neglect and sexual abuse did not differ between patients and German population with prevalence of 20.6% for emotional abuse, 20% for physical abuse, 22% for emotional neglect, 46% for physical neglect, and 6% for sexual abuse in patients with CTEPH. Higher CTQ scores were associated with anxiety symptoms as well as negatively associated with QoL. No direct impact of childhood trauma on CTEPH severity was found.

Conclusion

We found a higher rate of child maltreatment in patients with CTEPH in comparison to the German population. Correlations suggest moderate associations between CTQ scores and mental health and QoL. Child maltreatment had no significant impact on disease severity. Further investigation on proper interventions to support affected patients is needed.

Life-Course Influence of Adolescent Behaviour Problems on Type 2 Diabetes in Midlife: Results from 1958 British Birth Cohort Study

PURPOSE

To assess whether there is a long-term relationship between childhood behaviour problems and type 2 diabetes in midlife. The study will also investigate whether any of such relationship is independent of other factors which may be associated with type 2 diabetes.

DESIGN

Cohort study.

PARTICIPANTS

A total of 9377 members of the 1958 British birth cohort participated in the biomedical survey at age 45 years. The cohort has been followed up at regular intervals in childhood (age 7, 11 and 16 years) and adulthood (23, 33, 42 and 45 years).

PREDICTOR VARIABLES

Information regarding childhood behaviour collected during follow-ups at ages 7, 11 and 16 years.

MAIN OUTCOME VARIABLES

Type 2 diabetes assessed using HbA1c at age 45 years.

RESULTS

Unadjusted estimates show that teachers reported adolescent behaviour problems at age of 16 are associated with increased risk of type 2 diabetes in midlife. After adjustment for potential confounders and mediators in childhood and adulthood, a relationship was observed between the severity of adolescent behaviour problems and type 2 diabetes risk in midlife (mild behaviour problems: OR 2.17, 95% CI 1.11-4.23; severe behaviour problems: OR 4.40, 95% CI 1.14-16.99). However, no such relationship was observed between behaviour problems at 7 and 11 years and type 2 diabetes in midlife.

CONCLUSION

There is an association between adolescent behaviour problems and an increased risk of type 2 diabetes in midlife. Further molecular/genetic studies are required to understand the biological basis for this observed association.

Sexual violence and cardiovascular disease risk: A systematic review and meta-analysis

BACKGROUND

Cardiovascular disease (CVD) is a leading cause of death among adults. Over 35% of women worldwide report lifetime exposure to sexual violence. While psychosocial factors broadly have been linked to CVD risk, it is unclear if a history of sexual violence is associated with increased risk for CVD. This study employed quantitative meta-analysis to investigate the association between sexual violence and CVD risk.

METHODS

PubMed and PsycINFO databases were searched through March 1, 2021. Included articles had a measure of sexual violence and at least one cardiovascular outcome (i.e., clinical CVD, subclinical CVD, select CVD risk factors) in women and men aged 18 years or older. Data were expressed as odds ratios (OR) or hazard ratios (HR) with 95% confidence intervals (CI) extracted from fully-adjusted models. OR and HR effects were pooled separately, given the inability to statistically harmonize these effects and differences in interpretation, using random effects meta-analysis. Heterogeneity of effects was tested using Cochran's Q test.

RESULTS

Overall, 45 articles based on 830,579 adults (77.1% women) were included (113 individual effects expressed as OR and 9 individual effects expressed as HR). Results indicated that sexual violence was related to adult CVD risk (OR [95%CI] = 1.25 [1.11-1.40]; HR [95%CI] = 1.17 [1.05-1.31]). Results varied by outcome type and measurement, and timing of violence.

CONCLUSIONS

Adults with a history of sexual violence demonstrate greater CVD risk relative to those without this history. The results highlight the importance of addressing sexual violence in CVD risk reduction efforts.

Associations between prospective and retrospective measures of child abuse and self-reported adult health at midlife

BACKGROUND

The long-term health effects of physical child abuse are well documented in self-report, retrospective studies. However, there have been few longitudinal, multimethod studies on physiological responses to stress and the onset of chronic disease, thereby slowing the advancement of prevention and intervention programs.

OBJECTIVES

This study used survey data from an extended longitudinal study to examine prospective and retrospective associations between measures of physical child abuse and adult health in the 40s.

PARTICIPANTS AND SETTING

Data are from an ongoing longitudinal study of the correlates and consequences of child maltreatment that began in the 1970s with a sample of 457 children.

METHODS

Bivariate correlations and multiple regression models with covariates were used to assess associations between measures of physical child abuse and outcomes of self-reported health in adulthood.

RESULTS

Physical child abuse, measured retrospectively, was moderately related to reports of overall health, as well as a number of adult health problems and conditions, such as back and chest pain, hypertension, and certain forms of cancer. Associations were also observed for lifetime alcohol problems and past-year doctor and emergency room visits. Fewer associations between prospective parent self-report measures of physical child abuse and adult health were identified, although child welfare (official record) reports performed similarly to retrospective measures.

CONCLUSIONS

This study adds important information on the long-term health effects of child physical abuse, as well as measurement differences in the prediction of adult health outcomes. Conclusions drawn from prospective and retrospective studies of abuse are at best inconsistent, and possibly incompatible.

Early Life Adversity and Polygenic Risk for High Fasting Insulin Are Associated With Childhood Impulsivity

While the co-morbidity between metabolic and psychiatric behaviors is well-established, the mechanisms are poorly understood, and exposure to early life adversity (ELA) is a common developmental risk factor. ELA is associated with altered insulin sensitivity and poor behavioral inhibition throughout life, which seems to contribute to the development of metabolic and psychiatric disturbances in the long term. We hypothesize that a genetic background associated with higher fasting insulin interacts with ELA to influence the development of executive functions (e.g., impulsivity in young children). We calculated the polygenic risk scores (PRSs) from the genome-wide association study (GWAS) of fasting insulin at different thresholds and identified the subset of single nucleotide polymorphisms (SNPs) that best predicted peripheral insulin levels in children from the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort [N = 467; p_{t– initial} = 0.24 (10,296 SNPs), p_{t– refined} = 0.05 (57 SNPs)]. We then calculated the refined PRS (rPRS) for fasting insulin at this specific threshold in the children from the Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN) cohort and investigated its interaction effect with adversity on an impulsivity task applied at 36 months. We found a significant effect of interaction between fasting insulin rPRS and adversity exposure predicting impulsivity measured by the Snack Delay Task at 36 months [β = −0.329, p = 0.024], such that higher PRS [β = −0.551, p = 0.009] was linked to more impulsivity in individuals exposed to more adversity. Enrichment analysis (MetaCore^TM) of the SNPs that compose the fasting insulin rPRS at this threshold was significant for certain nervous system development processes including dopamine D2 receptor signaling. Additional enrichment analysis (FUMA) of the genes mapped from the SNPs in the fasting insulin rPRS showed enrichment with the accelerated cognitive decline GWAS. Therefore, the genetic background associated with risk for adult higher fasting insulin moderates the impact of early adversity on childhood impulsivity.

The Interplay between Child Maltreatment and Stressful Life Events during Adulthood and Cardiovascular Problems-A Representative Study

Psychological stress is a major risk factor for cardiovascular diseases. While the relevance of early life stress, such as that which is due to child maltreatment (CM), is well known to impact individual stress responses in the long-term, and data on the interplay between CM and stressful events in adulthood on cardiovascular health are sparse. Here, we aimed to assess how stressful life events in adulthood are associated with cardiovascular health infarction in later life and whether this association is independent of CM. In a cross-sectional design, a probability sample of the German population above the age of 14 was drawn using different sampling steps. The final sample included 2510 persons (53.3% women, mean age: 48.4 years). Participants were asked about sociodemographic factors, adult life events, CM, and health conditions in adulthood. Results indicate that the number of experienced adverse life events in adulthood is associated with significantly increased odds for obesity (Odds Ration (OR)women = 1.6 [1.3; 2.0], ORmen = 1.4 [1.1; 1.9]), diabetes (ORwomen = 1.5 [1.1; 2.1], ORmen = 1.5 [1.1; 2.3]) and myocardial infarction (ORwomen = 2.1 [1.0; 4.3], ORmen = 1.8 [1.1; 2.8]). This association is not moderated by the experience of CM, which is associated with cardiovascular problems independently. Taken together, adult stressful life events and CM are significantly and independently associated with cardiovascular health in men and women in the German population in a dose-dependent manner. General practitioners, cardiologists and health policy-makers should be aware of this association between psychosocial stressors during childhood and adulthood and cardiovascular health.

Germ Cell Drivers: Transmission of Preconception Stress Across Generations

Exposure to stress can accelerate maturation and hasten reproduction. Although potentially adaptive, the trade-off is higher risk for morbidity and mortality. In humans, the intergenerational effects of stress have been demonstrated, but the precise mechanisms are unknown. Strikingly, even if parental stress occurs prior to conception, as adults, their offspring show worse mental and physical health. Emerging evidence primarily from preclinical models suggests that epigenetic programming may encode preconception stress exposures in germ cells, potentially impacting the phenotype of the offspring. In this narrative review, we evaluate the strength of the evidence for this mechanism across animals and humans in both males and females. The strongest evidence comes from studies of male mice, in which paternal preconception stress is associated with a host of phenotypic changes in the offspring and stress-induced changes in the small non-coding RNA content in sperm have been implicated. Two recent studies in men provide evidence that some small non-coding RNAs in sperm are responsive to past and current stress, including some of the same ones identified in mice. Although preliminary evidence suggests that findings from mice may map onto men, the next steps will be (1) considering whether stress type, severity, duration, and developmental timing affect germ cell epigenetic markers, (2) determining whether germ cell epigenetic markers contribute to disease risk in the offspring of stress-exposed parents, and (3) overcoming methodological challenges in order to extend this research to females.

Could teacher-perceived parental interest be an important factor in understanding how education relates to later physiological health? A life course approach

Education is associated with later health, and notably with an indicator of physiological health measuring the cost of adapting to stressful conditions, named allostatic load. Education is itself the result of a number of upstream variables. We examined the origins of educational attainment through the lens of interactions between families and school i.e. parents’ interest in their child’s education as perceived by teachers. This study aims to examine whether parental interest during a child’s educational trajectory is associated with subsequent allostatic load, and whether education or other pathways mediate this relationship. We used data from 9 377 women and men born in 1958 in Great Britain and included in the National Child Development Study to conduct secondary data analyses. Parental interest was measured from questionnaire responses by teachers collected at age 7, 11 and 16. Allostatic load was defined using 14 biomarkers assayed in blood from a biosample collected at 44 years of age. Linear regression analyses were carried out on a sample of 8 113 participants with complete data for allostatic load, missing data were imputed. Participants whose parents were considered to be uninterested in their education by their teacher had a higher allostatic load on average in midlife in both men (β = 0,41 [0,29; 0,54]) and women (β = 0,69 [0,54; 0,83]). We examined the role of the educational and other pathways including psychosocial, material/financial, and behavioral variables, as potential mediators in the relationship between parental interest and allostatic load. The direct link between parental interest and allostatic load was completely mediated in men, but only partially mediated in women. This work provides evidence that parents’ interest in their child’s education as perceived by teachers is associated with subsequent physiological health in mid-life and may highlight a form of cultural dissonance between family and educational spheres.

Early Origins of Body Mass in Later Life: Examining Childhood Risks and Adult Pathways

Prior research reveals that negative early-life experiences play a major role in the development of obesity in later life, but few studies identify mechanisms that alter the lifetime risk of obesity. This study examines the influence of negative childhood experiences on body mass index (BMI) and obesity (BMI ≥30) during older adulthood and the psychosocial and behavioral pathways involved. Using a nationally representative sample, we examine the influence of cumulative misfortune as well as five separate domains of misfortune on BMI and obesity. Results show that four of the five domains are associated with BMI and obesity either directly, indirectly, or both. The influence of cumulative misfortune on the outcomes is mediated by three adult factors: socioeconomic status, depressive symptoms, and physical activity. The mediators identified here provide targets for intervention among older adults to help offset the health risks of excess BMI attributable of early-life exposure to misfortune.

Depression in midlife women attending a menopause clinic is associated with a history of childhood maltreatment

A growing body of literature has suggested that the perimenopause and the early postmenopausal years are associated with an increased risk of experiencing symptoms of depression and the development of first-onset and recurrent episodes of major depressive disorder. Multiple risk factors have been identified, including stressful life events and lower socioeconomic status, as well as early life adversity. The objective of the current study was to characterize the influence of early life childhood maltreatment and incident depression among women experiencing bothersome menopausal symptoms. Participants were recruited from two university-affiliated specialty clinics caring for women with bothersome menopausal symptoms. Assessments included the Childhood Trauma Questionnaire (CTQ), the Center for Epidemiological Studies - Depression (CES-D) scale and the Greene Climacteric Scale. Findings from this cross-sectional study indicate that adverse childhood experiences, as measured using the CTQ, were highly prevalent among women seeking care for bothersome menopausal symptoms (66%). Further, a greater score on the CTQ was significantly associated with higher CES-D scores, as well as with a greater burden of menopausal symptoms, after adjusting for confounding. Our findings lend support to the growing body of literature suggesting that early life stress affects mental health well into adulthood.

Early Life Exposure to Food Contaminants and Social Stress as Risk Factor for Metabolic Disorders Occurrence?-An Overview

The global prevalence of obesity has been increasing in recent years and is now the major public health challenge worldwide. While the risks of developing metabolic disorders (MD) including obesity and type 2 diabetes (T2D) have been historically thought to be essentially driven by increased caloric intake and lack of exercise, this is insufficient to account for the observed changes in disease trends. Based on human epidemiological and pre-clinical experimental studies, this overview questioned the role of non-nutritional components as contributors to the epidemic of MD with a special emphasis on food contaminants and social stress. This overview examines the impact of early life adverse events (ELAE) focusing on exposures to food contaminants or social stress on weight gain and T2D occurrence in the offspring and explores potential mechanisms leading to MD in adulthood. Indeed, summing up data on both ELAE models in parallel allowed us to identify common patterns that appear worthwhile to study in MD etiology. This overview provides some evidence of a link between ELAE-induced intestinal barrier disruption, inflammation, epigenetic modifications, and the occurrence of MD. This overview sums up evidence that MD could have developmental origins and that ELAE are risk factors for MD at adulthood independently of nutritional status.

Stress that Endures: Influence of Adverse Childhood Experiences on Daily Life Stress and Physical Health in Adulthood

BACKGROUND

Understanding the influence of ACEs on reported daily stress is needed to further address the role of ACEs on adult health and well-being.

METHODS

Data from 3,235 adults in the Midlife in the US (MIDUS) (Wave 1 (1995-1996) and Wave II (2004-2006)) were used. ACEs included emotional and physical abuse, household dysfunction, and financial strain. Daily stress was assessed using the National Study of Daily Experiences survey. Generalized Estimating Equations were used to examine the relationship between ACEs and Daily Stress.

RESULTS

ACE exposure was associated with higher number of reported stressors per day (p<.05), stressor severity (p<.05), number of physical symptoms reported (p<.05), and negative affect (p<.05). ACE count was significantly associated with multiple stressor types (OR=1.73, 95% 1.05-2.82) and number of days reported with stressor (RR=1.14, 95% 1.00-1.30). Abuse specifically was associated with a higher number of days reported with a stressor (RR=1.23, 95% CI 1.16 - 1.30).

LIMITATIONS

Assessment of ACEs is retrospective and self-reported. Secondly, this data is limited by ACE category. Specifically, sexual abuse and other forms of family dysfunction were not included in this dataset.

CONCLUSIONS

ACEs are associated with increased report of daily stress as an adult, reported physical symptoms as a result of stress, and reports of poor negative affect in adulthood. These findings highlight the role that ACEs play in the occurrence of reported daily stress during adulthood. Further investigation is needed to establish treatment and interventions for individuals who have experienced ACEs to avoid worsening health conditions and promote positive coping skills.

Associations Between Experience of Early Childhood Trauma and Impact on Obesity Status, Health, as Well as Perceptions of Obesity-Related Health Care

OBJECTIVE

To evaluate the association between obesity and history of childhood trauma in an effort to define implications for the provider-patient relationship and possible causes of failure of obesity treatment.

METHODS

Multisite survey developed by the Patient-Centered Outcomes Research Institute Learning Health Systems Obesity Cohort Workgroup consisting of 49 questions with 2 questions focusing on history of being a victim of childhood physical and/or sexual abuse was mailed to 19,964 overweight or obese patients. Data collection for this survey occurred from October 27, 2017, through March 1, 2018.

RESULTS

Among the 2211 surveys included in analysis, respondents reporting being a victim of childhood abuse increased significantly with obesity (23.6%, 26.0%, 29.1%, and 36.8% for overweight, class I, class II, and class III obesity, respectively; P<.001). A higher percentage of those who reported being a victim of childhood abuse noted that their weight issues began at an earlier age (P=.002) and were more likely to have weight-related comorbidities (P<.001), even after controlling for body mass index. Impacting physician counseling on weight loss, patients who were childhood victims of abuse reported lower self-esteem (P<.001), were more likely to feel judged by their health care providers (P=.009), and less likely to feel being treated with respect (P=.045).

CONCLUSION

Overall, being a victim of childhood abuse was significantly associated with obesity, lower self-esteem and negative experiences interacting with health care providers. Health care providers should receive training to ensure open and nonjudgmental visits with obese patients and consider the role of trauma survivorship issues in patients' development of obesity and health care experiences.

The Biological and Social Determinants of Childhood Obesity: Comparison of 2 Cohorts 50 Years Apart

OBJECTIVE

To determine whether the same relationships between early-life risk factors and socioeconomic status (SES) with childhood body mass index (BMI) are observed in a modern cohort (2000) compared with a historic cohort (1947).

STUDY DESIGN

The relationships between early-life factors and SES with childhood BMI were examined in 2 prospective birth cohorts from the same region, born 50 years apart: 711 children in the 1947 Newcastle Thousand Families Study (NTFS) and 475 from the 2000 Gateshead Millennium Study (GMS). The associations between birth weight, breastfeeding, rapid infancy growth (0-12 months), early-life adversity (0-12 months), and parental SES (birth and childhood) with childhood BMI z-scores and whether overweight/obese (BMI >91st percentile using UK 1990 reference) aged 9 years were examined using linear regression, path analyses, and logistic regression.

RESULTS

In the NTFS, the most advantaged children were taller than the least (+0.91 height z-score, P = .001), whereas in GMS they had lower odds of overweight/obese than the least (0.35 [95% CI 0.14-0.86]). Rapid infancy growth was associated with increased BMI z-scores in both cohorts, and with increased likelihood of overweight/obese in GMS.

CONCLUSIONS

This study suggests that children exposed to socioeconomic disadvantage or who have rapid infancy growth in modern environments are now at lower risk of growth restriction but greater risk of overweight.

Does maternal separation accelerate maturation of perineuronal nets and parvalbumin-containing inhibitory interneurons in male and female rats?

•

Maternal separation did not accelerate maturation of PNNs in amygdala or PFC.

•

Maternal separation did not affect PV density in infant and juveniles.

•

No sex differences were observed in effects of maternal separation on PNNs or PV.

•

Impact of early adversity may be more easily seen with functional neural measures.

Early life adversity impacts on a range of emotional, cognitive, and psychological processes. A recent theoretical model suggests that at least some of these effects are due to accelerated maturation of specific physiological systems and/or neural circuits. For example, maternal separation (MS), a model of early life adversity in rodents, accelerates maturation of memory systems, and here we examined its impact on maturation of perineuronal nets (PNNs) and parvalbumin (PV)-containing inhibitory interneurons. PNNs are specialized extracellular matrix structures suggested to be involved in stabilizing long-term memories and in the closure of a sensitive period in memory development. PV-containing inhibitory interneurons are the type of cell that PNNs preferentially surround, and are also thought to be involved in memory. In Experiment 1, with male rats, there was an increase in PNNs in both the amygdala and prefrontal cortex with age from infancy to juvenility. Contrary to prediction, MS had no impact on either PNN or PV expression. The same pattern was observed in female rats in Experiment 2. Taken together, these data show that the early maturation of memory in MS infants is not due to an accelerated maturation of PNNs or PV-containing cells in either the amygdala or prefrontal cortex.

Physical and sexual abuse in childhood and adolescence and leukocyte telomere length: A pooled analysis of the study on psychosocial stress, spirituality, and health

Introduction

We examined whether abuse in childhood and/or adolescence was associated with shorter telomere length in a pooled analysis of 3,232 participants from five diverse cohorts. We also assessed whether religion or spirituality (R/S) could buffer deleterious effects of abuse.

Methods

Physical and sexual abuse in childhood (age <12) and adolescence (age 12–18) was assessed using the Revised Conflict Tactics Scale and questions from a 1995 Gallup survey. We measured relative leukocyte telomere lengths (RTL) using quantitative real time polymerase chain reaction. We used generalized estimating equations to assess associations of physical and sexual abuse with log-transformed RTL z-scores. Analyses were conducted in each cohort, overall, and stratified by extent of religiosity or spirituality and religious coping in adulthood. We pooled study‐specific estimates using random‐effects models and assessed between-study heterogeneity.

Results

Compared to no abuse, severe sexual abuse was associated with lower RTL z-scores, in childhood: -15.6%, 95% CI: -25.9, -4.9; p-trend = 0.04; p-heterogeneity = 0.58 and in adolescence: -16.5%, 95% CI: -28.1, -3.0; p-trend = 0.08; p-heterogeneity = 0.68. Sexual abuse experienced in both childhood and adolescence was associated with 11.3% lower RTL z-scores after adjustment for childhood and demographic covariates (95% CI: -20.5%, -2.0%; p-trend = 0.03; p-heterogeneity = 0.62). There was no evidence of effect modification by R/S. Physical abuse was not associated with telomere length.

Conclusions

Sexual abuse in childhood or adolescence was associated with a marker of accelerated biological aging, decreased telomere length. The lack of moderation by R/S may be due to inability to capture the appropriate time period for those beliefs and practices.

An overview of child maltreatment (neglect and abuse) associations with developmental trajectories and long-term outcomes in the 1958 British birth cohort

Childhood maltreatment types (neglect and psychological, physical, or sexual abuse) are associated with many poor outcomes in adulthood. Yet, research mainly focuses on the cumulative adversity burden rather than specificities and commonalities of associations with adult outcomes and intervening pathways. To build understanding of life-course pathways to a range of outcomes, this overview summarises evidence from several original research studies using the 1958 British Birth Cohort on specific maltreatment types, child development trajectories, adult intermediaries and outcomes. About one-in-five participants were identified as neglected or abused in childhood (~10% were identified for neglect, 10% for psychological abuse, 6% for physical abuse and 1.4% for sexual abuse). Neglect was associated with key dimensions of development, for example, slower height growth, delayed maturation, faster BMI gain, and poorer emotional and cognitive development. Associated adulthood outcomes included harmful behaviours (notably smoking), poorer physical health (e.g. shorter height, excess BMI, poorer blood lipids and glucose, poor-rated health and physical functioning), worse mental health, lower socioeconomic circumstances (e.g. poorer living conditions) and elevated mortality in mid-adulthood. Childhood abuse associations were less widespread and were often only for specific types: most types were unrelated to childhood height and cognitive abilities, but all types were associated with poorer child emotional development, adult mental health, smoking, blood lipids and self-rated health. Additionally, physical abuse was associated with faster BMI gain, higher adult BMI, blood glucose, inflammation and mortality in mid-adulthood; sexual abuse with faster BMI gain, higher adult BMI, poor physical functioning at 50y and higher mortality in mid-adulthood. Adult health measures associated with neglect and abuse are key predictors of serious disease, disability and death. Therefore, neglect and abuse associations with these measures represent an important burden for individuals and society.

Assessing Life Stress: A Critical Priority in Obesity Research and Treatment

Significant childhood adversity and chronic life stress are highly prevalent in patients with severe obesity. Such stress has been found to increase risk of adulthood obesity by up to 50%, and it can also substantially degrade the effectiveness of evidence-based treatments for this chronic disease condition. Despite general appreciation of these facts, though, stress is not frequently measured in obesity research or routinely assessed during treatment for obesity or obesity-related complications. To address this important issue, we describe several validated tools that can be used for assessing life stress and discuss how information obtained from these instruments can be integrated into obesity treatment and research. Given the documented relevance of stress for obesity, we argue that stress assessment and management should be included in clinical treatments for obesity and that stress should be routinely measured in studies examining the long-term effects of obesity and obesity treatment.

Childhood Poly-victimization Is Associated With Elevated Body Mass Index and Blunted Cortisol Stress Response in College Women

BACKGROUND

Childhood interpersonal violence is linked to obesity and central adiposity in adulthood. Victimization experiences are likely to co-occur within individuals, but few studies have examined poly-victimization in the context of obesity and central adiposity.

PURPOSE

The aim of this study is to evaluate the relationship between poly-victimization and body mass index (BMI) and waist circumference (WC) and to explore whether dysregulation of the hypothalamic-pituitary-adrenal axis, as measured by the cortisol stress response, mediates the relationship.

METHODS

Healthy undergraduate women were recruited for a laboratory study from an online survey that assessed six different childhood victimization experiences: physical abuse, sexual abuse, peer violence, intimate partner violence, community violence, and witnessing violence. Forty-four women were categorized as poly-victims (2-5 types of violence exposures) and 48 were controls (0 types of violence exposures). Salivary cortisol was measured before and after the Trier Social Stress Test. Cortisol stress response was analyzed by the area under the curve with respect to ground (AUCG).

RESULTS

Compared with controls, poly-victims had higher BMI (B = 2.03, p = .04) and lower cortisol AUCG (B = -6.70, p < .01), independent of covariates. Poly-victims showed blunted AUCG in response to the stress task compared with controls, independent of covariates (B = -6.70, p < .01). Bootstrapping tests of mediation showed that cortisol response was not a significant mediator of the relationship between poly-victimization and BMI. Secondary analyses among poly-victims showed that the more frequent the violence exposure the higher the BMI.

CONCLUSIONS

Childhood poly-victimization is linked to higher BMI and blunted cortisol responses in young adult women. Assessment of multiple forms of childhood victimization is recommended.

Childhood Adversities as Determinants of Cardiovascular Disease Risk and Perceived Illness Burden in Adulthood: Comparing Retrospective and Prospective Self-Report Measures in a Longitudinal Sample of African Americans

A large body of evidence suggests that exposure to childhood adversities increases risk for poor quality physical health in adulthood. Much of this evidence is based on retrospective measures which are believed to be contaminated by the limitations and biases of autobiographical memory. Using longitudinal data on 454 African Americans (61 percent female) this study examines the corroboration between prospective and retrospective measures of childhood adversities gathered approximately two decades apart, and the relative ability of the measures to predict self-reported illnesses and a biomarker of 30-year cardiovascular disease risk. Comparisons indicated that the retrospective and prospective measures demonstrated weak convergence and did not provide completely equivalent information about self-reported adverse childhood experiences. A series of regression models indicated that the two measures of adversities exhibited similar associations with the cardiovascular disease biomarker but divergent associations with self-reported illnesses. Furthermore, both the prospective and retrospective measures simultaneously predicted cardiovascular disease risk in adulthood. That the prospective measure did not significantly predict perceived illnesses after adjusting for the retrospective measure is evidence that childhood adversities predict self-reported health burden insofar as respondents remember those adversities as adults. The findings provide evidence that retrospective self-report measures of childhood adversities do not closely converge with prospective measures, and that retrospective measures may not provide valid estimates of the association between childhood adversities and perceived illnesses in adulthood.

Intergenerational transmission of the effects of maternal exposure to childhood maltreatment on offspring obesity risk: A fetal programming perspective

Childhood obesity constitutes a major global public health challenge. A substantial body of evidence suggests that conditions and states experienced by the embryo/fetus in utero can result in structural and functional changes in cells, tissues, organ systems and homeostatic set points related to obesity. Furthermore, growing evidence suggests that maternal conditions and states experienced prior to conception, such as stress, obesity and metabolic dysfunction, may spill over into pregnancy and influence those key aspects of gestational biology that program offspring obesity risk. In this narrative review, we advance a novel hypothesis and life-span framework to propose that maternal exposure to childhood maltreatment may constitute an important and as-yet-underappreciated risk factor implicated in developmental programming of offspring obesity risk via the long-term psychological, biological and behavioral sequelae of childhood maltreatment exposure. In this context, our framework considers the key role of maternal-placental-fetal endocrine, immune and metabolic pathways and also other processes including epigenetics, oocyte mitochondrial biology, and the maternal and infant microbiomes. Finally, our paper discusses future research directions required to elucidate the nature and mechanisms of the intergenerational transmission of the effects of maternal childhood maltreatment on offspring obesity risk.

Increased Cardiometabolic and Mortality Risk Following Childhood Maltreatment in the United Kingdom

Background

Childhood maltreatment remains a significant public health issue associated with a number of poor health outcomes. This study explores the association between childhood maltreatment and the subsequent development of cardiometabolic disease and all‐cause mortality.

Methods and Results

Using a UK primary care database between January 1, 1995 and December 31, 2018, we conducted a population‐based open retrospective cohort study. We matched 80 657 adult patients with a historic recording of childhood maltreatment or maltreatment‐related concerns (exposed group) to 161 314 unexposed patients. Outcomes of interest were the development of cardiovascular disease, hypertension, type 2 diabetes mellitus, and risk of all‐cause mortality. During the study period there were 243 new diagnoses of cardiovascular disease (incidence rate 8.3 per 10 000 person‐years) in the exposed group compared with 254 in the unexposed group (incidence rate 4.6 per 10 000 person‐years). Following adjustment for key covariates, this translated to an adjusted incidence rate ratio of 1.71 (95% CI 1.42–2.06). Additionally, the exposed group had an increased risk of hypertension (adjusted incidence rate ratio 1.42; 95% CI, 1.26–1.59), type 2 diabetes mellitus (adjusted incidence rate ratio 2.13; 95% CI, 1.86–2.45) and all‐cause mortality (adjusted incidence rate ratio 1.75; 95% CI, 1.52–2.02) during the study period compared with the unexposed group.

Conclusions

Considering the high prevalence of exposure to childhood maltreatment, we have demonstrated the substantial associated burden of preventable cardiometabolic disease. There is a clear need to ensure that public health approaches are implemented to prevent the adverse consequences following exposure to childhood maltreatment.

Adverse Childhood Experiences and Health Care Utilization in a Low-Income Population

OBJECTIVE

To determine associations of adverse childhood experiences (ACE) with adult health care utilization in an underserved, low-income population.

METHODS

Questionnaires on ACE were completed by 38,200 adults (mean age 54), two-thirds African American, recruited from community health centers (CHCs) across 12 Southeastern states. Odds ratios (ORs) and accompanying 95% confidence intervals (CIs) were computed.

RESULTS

The percentages reporting emergency room visits and doctor's office visits, with high chronic disease index scores, rose monotonically (ptrend&lt;.001) with rising ACE score. Odds ratios (CIs) for those with four or more vs. zero ACEs were 1.37 (95% CI 1.27-1.47) for 1-10 times and 1.80 (95% CI 1.29-2.52) for more than 10 times ER visits, 1.37 (95% CI 1.18-1.59) for over 10 doctor's visits, and 2.29 (95% CI 2.06-2.54) for three or more chronic diseases.

CONCLUSIONS

High ACE levels were associated with greater chronic disease burden and greater health care utilization in adulthood. Long-lasting effects from ACE on the health care of underserved populations are indicated. There is an urgent need to train health care providers, patients, and their families on ACE effects and treatments for better health care outcomes.

Is exposure to family member incarceration during childhood linked to diabetes in adulthood? Findings from a representative community sample

Objectives:

Diabetes is a prevalent and serious public health problem, particularly among older adults. A robust literature has shown that adverse childhood experiences contribute to the development of health problems in later life, including diabetes. Family member incarceration during childhood is an under-investigated yet increasingly common adverse childhood experience in the United States. The purpose of this study was to investigate the relationship between family member incarceration during childhood and diabetes in adulthood, while considering the role of gender as well as the impact of a range of potential confounds.

Methods:

A large representative community sample of adults aged 40 and older (n = 8790 men, 14,255 women) was drawn from the Behavioral Risk Factor Surveillance System 2012 optional adverse childhood experiences module to investigate the association between family member incarceration during childhood and diabetes. For each gender, nine logistic regression analyses were conducted using distinct clusters of variables (e.g. socioeconomic status and health behaviors).

Results:

Among males, the odds of diabetes among those exposed to family member incarceration during childhood ranged from 2.00 to 1.59. In the fully adjusted model, they had elevated odds of 1.64 (95% confidence interval = 1.27, 2.11). Among women, the odds of diabetes was much lower, hovering around 1.00.

Conclusion:

Findings suggest that family member incarceration during childhood is associated with diabetes in men, even after adjusting for a wide range of potential risk factors (e.g. sociodemographics, health behaviors, healthcare access, and childhood risk factors). Future research should explore the mechanisms linking family member incarceration during childhood and long-term negative health outcomes in men.

Association of Adverse Childhood Experiences with Glycemic Control and Lipids in Children with Type 1 Diabetes

Adverse childhood experiences (ACE) have been associated with a greater prevalence of risky behaviors and chronic health conditions, such as diabetes in adulthood. While adolescents with risk taking behaviors experience worsening of diabetic metabolic control, it is yet to be determined whether glycemic management in children and adolescents is negatively and independently influenced by ACEs. This study examines the relationship between ACEs in children and adolescents with type 1 diabetes (T1DM) and glycemic control, BMI and lipids. For such children, we hypothesized that hemoglobin A1c (HbA1c) is positively correlated with ACE scores. Parents of children (age 2–18 years) with T1DM completed a validated ACE questionnaire. The associations between parent and child ACE score and HbA1c, lipids and BMI z-scores were assessed using linear regression. The prevalence of any ACE was 27.9% among children and 49.0% among parents. HbA1c was significantly higher in children who had exposure to three or more ACEs (β: 0.63 (4.5 mmol/mol); p = 0.02), in those who had a parent exposed to four or more ACEs (β: 0.87 (7.2 mmol/mol); p = 0.03), in children who had exposure to household incarceration (β: 0.62 (4.4 mmol/mol); p = 0.05) and children who witnessed or had been victim of violence in the neighborhood (β: 0.71 (5.4 mmol/mol); p = 0.02). ACEs were highly prevalent among children with T1DM and had a positive association with glycemic control.

Prenatal immobilization stress and postnatal maternal separation cause differential neuroendocrine responses to fasting stress in adult male rats

Prenatal immobilization stress (PNS) and postnatal maternal separation (MS180) are two widely used rodent models of early-life stress (ELS) that affect the hypothalamus-pituitary-adrenal (HPA) axis, cause behavioral alterations, and affect glucose tolerance in adults. We compared anxiety-like behavior, coping strategies, and HPA axis activity in PNS and MS180 adult (4-month-old) male rats and assessed their glucose tolerance and HPA axis response after mild fasting stress. Both PNS and MS180 induced a passive coping strategy in the forced swimming test, without affecting anxiety-like behavior in the elevated plus-maze. Moreover, both PNS and MS180 increased the hypothalamic corticotropin-releasing hormone expression; however, only MS180 increased the circulating corticosterone levels. Both early life stressors increased fasting glucose levels and this effect was significantly higher in PNS rats. MS180 rats showed impaired glucose tolerance 120 min after intravenous glucose administration, whereas PNS rats displayed an efficient homeostatic response. Moreover, MS180 rats showed higher circulating corticosteroid levels in response to fasting stress (overnight fasting, 12 hr), which were restored after glucose administration. In conclusion, early exposure to postnatal MS180, unlike PNS, increases the HPA axis response to moderate fasting stress, indicating a differential perception of fasting as a stressor in these two ELS models.
