Does childhood misfortune raise the risk of acute myocardial infarction in adulthood?

Adverse childhood experiences and all-cause mortality risk in adulthood

BACKGROUND

Adverse Childhood Experiences (ACEs) have been associated with mortality risk in adulthood. It is unclear, however, whether ACEs perpetrated beyond parents may be associated with mortality risk, if the risk is accumulative or plateaus at a certain frequency, whether associations differ dependent on ACE types, whether types interact with one another, or if observed effects differ by sex.

OBJECTIVE

To examine associations between ACEs and mortality risk.

PARTICIPANTS AND SETTING

6319 participants (age range 25-74 years, mean [SD] 46.91 [12.95] years; 51.6 % female) followed from 1995/96 to 2018 as part of the survey of Midlife Development in the United States.

METHODS

ACE variables were self-reported exposure to 20 ACE types from five categories: physical abuse, emotional abuse, socioeconomic disadvantage, adverse family structure, and poor health at age 16 years. Cox proportional hazards models were used to estimate mortality risk.

RESULTS

ACEs were accumulatively associated with increased mortality risk in adjusted models (HR = 1.033; p ≤ .001, 95 % CI, 1.014-1.053). The association was linear. Only physical abuse (HR = 1.05; p = .024, 95 % CI, 1.01-1.10) remained significantly predictive of increased mortality risk adjusting for other types. No interaction by sex or amongst ACE types was observed.

CONCLUSIONS

ACEs may be cumulatively associated with increased mortality risk, such that each individual ACE increases risk. Physical abuse may be an important ACE type within a mortality risk context. Individual ACE types warrant further study as each type may have their own differential impact on mortality risk.

The Long Arm of Prospective Childhood Income for Mature Adult Health in the United States

Pioneering scholarship links retrospective childhood conditions to mature adult health. We distinctively provide critical evidence with prospective state-of-the-art measures of parent income observed multiple times during childhood in the 1970s to 1990s. Using the Panel Study of Income Dynamics, we analyze six health outcomes (self-rated health, heart attack, stroke, life-threatening chronic conditions, non-life-threatening chronic conditions, and psychological distress) among 40- to 65-year-olds. Parent relative income rank has statistically and substantively significant relationships with five of six outcomes. The relationships with heart attack, stroke, and life-threatening chronic conditions are particularly strong. Parent income rank performs slightly better than alternative prospective and retrospective measures. At the same time, we provide novel validation on which retrospective measures (i.e., father's education) perform almost as well as prospective measures. Furthermore, we inform several perennial debates about how relative versus absolute income and other measures of socioeconomic status and social class influence health.

Matters of the Heart: Childhood Maltreatment, Religious Transitions, and Cardiovascular-Related Problems over the Life Course

Objectives:

Childhood maltreatment is associated with a higher risk of cardiovascular-related problems, the leading cause of death in the United States. Drawing from cumulative inequality theory, this study considers whether transitions in religious attendance moderate the deleterious impact of childhood maltreatment on long-term cardiovascular risk.

Methods:

We utilize over 35 years of prospective panel data from the National Longitudinal Study of Youth from the United States (1979–2015).

Results:

Our findings suggest that decreases in religious attendance between adolescence and adulthood (from high to low, and high to moderate attendance) were associated with elevated cardiovascular-related risk for those abused as children. Neither stable high attendance nor increases in attendance buffered against the impact of childhood abuse on cardiovascular-related problems.

Discussion:

We illustrate the importance of incorporating the role of stability and change in religious attendance across the life course and suggest directions for future research.

A Comprehensive Review on Multifaceted Mechanisms Involved in the Development of Breast Cancer Following Adverse Childhood Experiences (ACEs)

BACKGROUND AND AIM OF THE WORK

Adverse Childhood Experiences (ACEs) may give rise to harmful effects on health throughout life. Epigenetic changes explain how preexisting risk factors may contribute to produce altered biological responses and cancer risk. The main aim of the review is to summarize studies examining the means in which Adverse Childhood Experiences (ACEs) can modulate individual vulnerability to breast cancer (BC) development through multifaceted mechanisms.

METHODS

Studies selection, data extraction, and assessments agreed to PRISMA criteria. We included original research with clinical samples following BC interventions, investigating potential mechanisms linking ACEs and BC in adults.

RESULTS

From the 3321 papers found, nine articles involving 2931 participants were selected. All studies included ACEs retrospective assessments and psychological measures, and seven of them considered biomarkers. Individuals exposed to greater ACEs were at increased BC risk compared with individuals with no ACEs. Associations were found between child abuse and/or neglect, depression, perceived stress, fatigue, and plasma levels of cytokines interleukin (IL-6), C-reactive protein (CRP), soluble tumor necrosis factor receptor type II (sTNF-RII), interleukin IL-1 receptor antagonist (IL-1ra), and psycho-physiological adjustments that may lead to BC.

CONCLUSIONS

Exposure to multiple ACEs appears a risk factor for BC development in adulthood. Although the clinical relevance of findings such as this is ambiguous, the review added evidence for a link between the presence of childhood adversity and BC occurrence, pointing to psychological, hormonal, and immunological dysregulations.

Childhood Background Measures and Their Associations With Later-Life Physical, Mental, and Social Health in the National Social Life, Health, and Aging Project

OBJECTIVE

We describe each childhood background measure available in the National Social Life, Health, and Aging Project (NSHAP), report preliminary population estimates for each measure by age and gender, and validate the childhood measures by showing that the associations between the NSHAP childhood measures and later-life health outcomes are consistent with previous studies on this topic.

METHOD

Childhood background measures included family life happiness, family structure, parental educational attainment, perceived financial situation, experience of violence, witness of violence, childhood health, and place of birth. We measured self-rated health, depressive symptoms, and social support to assess later-life physical, mental, and social health. Logistic and linear regression models were used for the binary and continuous outcome variables, respectively.

RESULTS

Older age groups were more likely than those in younger age groups to report a poor financial situation in childhood, lower parental education, and intact family structure and were less likely to have experienced or witnessed a violent event as a child. Growing up in a happy and well-educated family was associated with better physical, mental, and social health in older ages.

DISCUSSION

NSHAP childhood data included a variety of measures assessing the family social environment during childhood, providing a valuable resource for the study of early-life determinants of health and well-being over the life course.

Adverse childhood experiences and incident coronary heart disease: a counterfactual analysis in the Whitehall II prospective cohort study

Objectives

Adverse childhood experience is thought to be associated with risk of coronary heart disease, but it is not clear which experiences are cardiotoxic, and whether risk increases with the accumulation of adverse childhood experiences.

Methods

Participants were 5149 adults (72.6% men) in the Whitehall II cohort study. Parental death was recorded at phase 1 (median age in years 44.3), and 13 other adverse childhood experiences at phase 5 (55.3). We applied Cox proportional hazards regression with person-time from phase 5 to examine associations of adverse childhood experiences with incident coronary heart disease. We predicted hazard ratios according to count of the experiences, and examined dose-response effect. We finally estimated reduction of coronary heart disease in a hypothetical scenario, the absence of adverse childhood experiences.

Results

Among study participants, 62.9% had at least one adversity, with "financial problems" having the highest prevalence (26.1%). There were 509 first episodes of coronary heart disease during an average 12.9 years follow-up. Among 14 adverse childhood experiences in a multiply adjusted model, "parental unemployment" showed the highest hazard of coronary heart disease incidence (hazard ratio; 95% confidence interval: 1.53; 1.16 to 2.02). No dose-response effect was observed (constant for proportionality in hazard ratio: 1.05, 0.99 to 1.11). Based on the estimates of final model, in the absence of childhood adversities, we estimated a 6.0% reduction in coronary heart disease (0.94; 0.87 to 1.01), but the confidence interval includes one.

Conclusion

Although individual adverse childhood experiences show some association with coronary heart disease, there is no clear relationship with the number of adverse experiences. Further research is required to quantify effects of multiple and combinations of adverse childhood experiences considering timing, duration, and severity.

The importance of child abuse and neglect in adult medicine

The risk for adverse consequences and disease due to the trauma of child abuse or neglect is easily assessed using the self-administered modified ACEs questionnaire. Exposure to child maltreatment is endemic and common. At least one out of every ten USA adults has a significant history of childhood maltreatment. This is a review of the literature documenting that a past history of childhood abuse and neglect (CAN) makes substantial contributions to physical disease in adults, including asthma, chronic obstructive pulmonary disease, lung cancer, hypertension, stroke, kidney disease, hepatitis, obesity, diabetes, coronary artery disease, pelvic pain, endometriosis, chronic fatigue syndrome, irritable bowel syndrome, fibromyalgia, and auto immune diseases. Adults who have experienced child maltreatment have a shortened life expectancy. The contribution of CAN trauma to these many pathologies remains largely underappreciated and neglected compared to the attention given to the array of mental illnesses associated with child maltreatment. Specific pathophysiolologic pathways have yet to be defined. Clinical recognition of the impact of past CAN trauma will contribute to the healing process in any disease but identifying specific effective therapies based on this insight remains to be accomplished. Recommendations are made for managing these patients in the clinic. It is important to incorporate screening for CAN throughout adult medical practice now.

Evaluating the Cumulative Impact of Childhood Misfortune: A Structural Equation Modeling Approach

Most studies of the early origins of adult health rely on summing dichotomously measured negative exposures to measure childhood misfortune (CM), neglect, adversity, or trauma. There are several limitations to this approach, including that it assumes each exposure carries the same level of risk for a particular outcome. Further, it often leads researchers to dichotomize continuous measures for the sake of creating an additive variable from similar indicators. We propose an alternative approach within the structural equation modeling (SEM) framework that allows differential weighting of the negative exposures and can incorporate dichotomous and continuous observed variables as well as latent variables. Using the Health and Retirement Study data, our analyses compare the traditional approach (i.e., adding indicators) with alternative models and assess their prognostic validity on adult depressive symptoms. Results reveal that parameter estimates using the conventional model likely underestimate the effects of CM on adult health outcomes. Additionally, while the conventional approach inhibits testing for mediation, our model enables testing mediation of both individual CM variables and the cumulative variable. Further, we test whether cumulative CM is moderated by the accumulation of protective factors, which facilitates theoretical advances in life course and social inequality research. The approach presented here is one way to examine the cumulative effects of early exposures while attending to diversity in the types of exposures experienced. Using the SEM framework, this versatile approach could be used to model the accumulation of risk or reward in many other areas of sociology and the social sciences beyond health.

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.

Childhood Risk Factors and Adulthood Cardiovascular Disease: A Systematic Review

OBJECTIVE

To conduct a comprehensive review of the literature on childhood risk factors and their associations with adulthood subclinical and clinical cardiovascular disease (CVD).

STUDY DESIGN

A systematic search was performed using the MEDLINE, EMBASE, PsycINFO, CINAHL, and Web of Science databases to identify English-language articles published through June 2018. Articles were included if they were longitudinal studies in community-based populations, the primary exposure occurred during childhood, and the primary outcome was either a measure of subclinical CVD or a clinical CVD event occurring in adulthood. Two independent reviewers screened determined whether eligibility criteria were met.

RESULTS

There were 210 articles that met the predefined criteria. The greatest number of publications examined associations of clinical risk factors, including childhood adiposity, blood pressure, and cholesterol, with the development of adult CVD. Few studies examined childhood lifestyle factors including diet quality, physical activity, and tobacco exposure. Domains of risk beyond "traditional" cardiovascular risk factors, such as childhood psychosocial adversity, seemed to have strong published associations with the development of CVD.

CONCLUSIONS

Although the evidence was fairly consistent in direction and magnitude for exposures such as childhood adiposity, hypertension, and hyperlipidemia, significant gaps remain in the understanding of how childhood health and behaviors translate to the risk of adulthood CVD, particularly in lesser studied exposures like glycemic indicators, physical activity, diet quality, very early life course exposure, and population subgroups.

The Effects of Childhood Circumstances on Health in Middle and Later Life: Evidence From China

Background: This study examined the relationship between childhood circumstances and health in middle and later life. We quantified how childhood circumstances contribute to health in later life, both directly and indirectly, through their effects on potential mediators.

Methods: This study used three waves of data from the national longitudinal survey of the China Health and Retirement Longitudinal Study (CHARLS). The final model in this study included 7,476 eligible respondents aged 45 years and above. We constructed a simple health status measure based on the first principal component of CHARLS survey responses with 25 health-related information. It is a multi-dimensional measurement that comprehensively reflects the individual's healthy aging. We formulated childhood circumstances factors into five domains: childhood health and nutrition, childhood socioeconomic status, access to health care, parental genetics, and adverse childhood experiences. Ordered logit regression was conducted to analyze the relationship between health in middle and later life and childhood circumstances, with other explanatory variables controlled.

Results: Controlling for educational attainment, personal income, and health status in the last wave, adults who experience good childhood health (poor as the base, coefficient 0.448, p < 0.01), and better family financial status (worse as the base, coefficient 0.173, p < 0.01) have significantly better health during their middle and later life, in comparison, being inconvenient to visit a doctor (coefficient −0.178, p < 0.01), and having two or three adverse childhood experiences (0 as the base, coefficient −0.148, p < 0.01) are significantly associated with poorer health. Childhood circumstances appear to act both through a lasting effect of initial health and financial status in childhood and through their impact on achievements in adulthood.

Conclusion: Our findings suggest that investments in health during childhood not only contribute to health in later life but also dynamically improve an individual's educational attainment and personal income, as well as other life prospects. All these returns may extend far beyond childhood and continue throughout the lifespan.

Early Social Origins of Biological Risks for Men and Women in Later Life

We investigate whether childhood exposures influence adult chronic inflammation and mortality risk via adult health characteristics and socioeconomic status (SES) and whether gender moderates these relationships. Analyzing a longitudinal national sample of 9,310 men and women over age 50, we found that childhood SES, parental behaviors, and adolescent behaviors were associated with adult chronic inflammation via health characteristics and SES in adulthood. The process of disadvantage initiated by low childhood SES (i.e., adult health risk factors, socioeconomic disadvantage, and chronic inflammation) subsequently raised mortality risk. In addition, gender moderated the mediating influence of childhood SES via unhealthy behaviors and parental behaviors via adult SES. Demonstrating how social forces shape biological health through multiple mechanisms informs health policies by identifying multiple points of intervention in an effort to reduce the lasting consequences of childhood disadvantage.

Childhood Misfortune and Late-Life Stroke Incidence, 2004-2014

BACKGROUND AND OBJECTIVES

Although most strokes occur in later life, recent studies reveal that negative exposures decades earlier are associated with stroke risk. The purpose of this study was to examine whether accumulated and/or specific domains of early misfortune are related to stroke incidence in later life.

RESEARCH DESIGN AND METHODS

A decade of longitudinal data from stroke-free participants 50 years or older in the Health and Retirement Study were analyzed (N = 12,473). Incident stroke was defined as either self-reported first incident stroke or death due to stroke between 2004 and 2014.

RESULTS

Analyses revealed that accumulated misfortune was associated with increased stroke risk, but the relationship was moderated by wealth. Examining specific domains of childhood misfortune revealed that stroke incidence was greater for persons with behavioral/psychological risks, but that this relationship also was moderated by higher wealth for those with only one behavioral/psychological risk.

DISCUSSION AND IMPLICATIONS

Accumulated childhood misfortune and adolescent depression heighten the risk of stroke in later life, but the influence is remediable through adult wealth. Reducing poverty in later life may decrease stroke incidence for persons exposed to negative childhood exposures.

Does early peer relationship last long? The enduring influence of early peer relationship on depression in middle and later life

BACKGROUND

Previous studies focus on the health effect of early family relationship rather than early peer relationship. Thus, this study aimed to examine the causal effect of early peer relationship on depression in middle and later life.

METHODS

Based on the China Health and Retirement Longitudinal Study data 2013-2014 (N = 15,343), this study used the propensity score matching approach to estimate the causal effect of early peer relationship, including establishment (whether having good friends in childhood), engagement (frequency of playing with friends in childhood) and feeling (feeling of loneliness in childhood), on depression in middle and later life, as well as the educational heterogeneity of this health effect.

RESULTS

Elevated feeling of loneliness and reduced engagement of early peer relationship were causally related to elevated depression in middle and later life, but having good friends in childhood was not related to later life depression. For individuals with more education, less feeling of loneliness in childhood had a stronger effect on reduced depression in middle and later life, but more engagement in childhood peer relationship only had a weaker effect on reduced depression in middle and later life.

LIMITATIONS

A retrospective survey and single-item measures of early peer relationship were used, the intermediate link across the life course and potential neurobiological mechanisms were also not empirically examined.

CONCLUSIONS

We should focus more on the engagement and quality of early peer relationship, as well as the balance between education and socializing in childhood, to prevent from the detrimental health effect of early peer relationship disadvantage.

Recession hardships, personal control, and the amplification of psychological distress: Differential responses to cumulative stress exposure during the U.S. Great Recession

Recessions pose risks to mental health, yet the psychosocial mechanisms involved are less clear. One critical factor may be people's perceived control when faced with multiple recession hardships. Here we test a structural amplification hypothesis by assessing the role of perceived control as a mediator and moderator of the relation between recession shocks and psychological distress. We draw on waves 2 (2004-2006) and 3 (2013-2014) of the Midlife in the United States study (MIDUS), covering 1,739 US adults under age 75 from before and after the Great Recession. Our statistical models reveal that perceived control declines while distress rises in association with a greater accumulation of recession-related hardships. Perceived control partially mediated the recession hardships-distress association,attenuating it by about one-fifth. Further, perceived control modified the association between recession hardships and distress; individuals who reported larger declines in personal control had greater increases in distress, whereas those who experienced hardships but increased their perceived control did not exhibit significant changes in distress levels. Taken together, our findings support the structural amplification hypothesis, whereby an accumulation of recession hardships erode coping resources that would otherwise protect individuals from the mental health effects of stress exposure. Future research is needed to better understand sources of resilience at individual, community, and societal levels to help ameliorate sentiments of powerlessness and lack of perceived control during economic recessions.

Childhood Misfortune and Handgrip Strength Among Black, White, and Hispanic Americans

OBJECTIVE

Although early-life insults may affect health, few studies use objective physical measures of adult health. This study investigated whether experiencing misfortune during childhood is associated with handgrip strength (HGS) in later life.

METHOD

Data on childhood misfortune and adult characteristics from the Health and Retirement Study were used to predict baseline and longitudinal change in HGS among White, Black, and Hispanic American men and women.

RESULTS

Regression analyses revealed that multiple indicators of childhood misfortune were related to HGS at baseline, but the relationships were distinct for men and women. Over the study, having one childhood impairment predicted steeper declines in HGS for men, but childhood misfortune was unrelated to HGS change among women. Hispanic Americans had lower baseline HGS than their non-Hispanic counterparts and manifested steeper declines in HGS.

DISCUSSION

The relationship between childhood exposures and adult HGS varied by the type of misfortune, but there was no evidence that the relationship varied by race/ethnicity. The significant and enduring Hispanic disadvantage in HGS warrants greater attention in gerontology.

Childhood maltreatment as a risk factor for cancer: findings from a population-based survey of Canadian adults

BACKGROUND

Childhood maltreatment (CM) is an established risk factor for various mental and substance use disorders. This study adds to existing evidence that CM may also be a risk factor for cancer.

METHODS

Based on data from a sample of 9783 men and 12,132 women from the 2012 Canadian Community Health Survey - Mental Health (CCHS-MH), this analysis explores mediated associations between cancer in adulthood and different levels of exposure to three types of CM-childhood physical abuse (CPA), childhood sexual abuse (CSA), and childhood exposure to intimate partner violence (CEIPV). "Cancer" was defined as an affirmative response to either of these questions: "Do you have cancer?" or "Have you ever been diagnosed with cancer?" The potential mediators were: smoking, depression, alcohol abuse/dependence, life stress, obesity, and physical activity.

RESULTS

For women, but not men, having experienced CM was significantly associated with a cancer diagnosis in adulthood, even when effects due to age and socio-demographic characteristics were controlled. Smoking, life stress, depression, and alcohol abuse/dependence reduced the strength of the association between CM and cancer in women. However, most associations remained statistically significant when controlling for effects due to these behavioural and other mediators. Evidence indicated a "dose-response" relationship, in that the likelihood of reporting cancer increased with the number of abuse types (CPA, CSA, CEIPV) reported, and with the severity of CPA.

CONCLUSIONS

The analyses suggest an association between CM and cancer in women, even when the effects of known risk factors were taken into account. The association was graded, becoming stronger as CM exposure increased. Implications for the provision of cancer screening and other health care services to women with histories of CM to reduce health disparities are discussed.

Associations between childhood maltreatment and risk of myocardial infarction in adulthood: Results from the National Epidemiologic Survey on alcohol and Related Conditions

OBJECTIVE

Although childhood maltreatment has been reported to be associated with the incidence of cardiovascular diseases, its association with specific major cardiovascular events remains unclear. This study aimed to examine the relationship between different types of childhood maltreatment (CM) and myocardial infarction (MI) occurrence in a nationally representative sample.

METHODS

We used data from the National Epidemiologic Survey of Alcohol and Related Conditions, a nationally representative US sample of adults aged 20 years and older (N = 34, 653). Logistic regression models were constructed to investigate the associations between five types of CMs including physical abuse, physical neglect, emotional abuse, emotional neglect, and sexual abuse and the risk of MI adjusting for sociodemographic variables.

RESULTS

After adjusting for sociodemographic variables, childhood sexual abuse was significantly associated with increased odds of MI occurrence (adjusted odds ratio [aOR] = 1.85, 95%CI = 1.24-2.76, p = 0.003). Additionally, childhood physical abuse was significantly associated with increased odds of MI occurrence in men (aOR = 2.45, 95%CI = 1.35-4.44, p = 0.004) but this association was not observed in women (aOR = 0.72, 95%CI = 0.32-1.66, p = 0.440). Compared to those who did not experience CM, those who experienced more than three types of CMs showed increased odds of MI occurrence (adjusted OR = 2.08-3.05, all p < 0.05).

CONCLUSIONS

Using data from a nationally representative US sample of adults, we found significant positive associations between CM and odds of MI occurrence in adulthood. Future longitudinal prospective studies are needed to confirm our findings.

The Long Arm of Maternal Differential Treatment: Effects of Recalled and Current Favoritism on Adult Children's Psychological Well-Being

Objectives

In this article, we draw from classic theories of social psychology and the life course to compare the effects of current and recalled perceived maternal differential treatment (MDT) on the depressive symptoms of adult children in midlife.

Method

To address this question, we used data collected from 746 adult children nested within 293 later-life families as part of the Within-Family Differences Study.

Results

Multilevel regression revealed that both recollections of maternal differentiation from childhood and perceptions of mothers' current disfavoritism regarding conflict predicted depressive symptoms, whereas perceptions of current favoritism regarding emotional closeness did not.

Discussion

Taken together, the findings from this investigation reflect principles of theories of social comparison and the life course in that both perceptions of current MDT and MDT recalled from childhood affect children's well-being in midlife. These findings contribute to a growing body of literature highlighting the role of within-family differences in parent-child relationships on well-being across the life course.

Avoiding the Major Causes of Death: Does Childhood Misfortune Reduce the Likelihood of Being Disease Free in Later Life?

Objectives

Although previous research reveals the detrimental effects of early misfortune on the development of chronic diseases in later life, few studies have investigated its effects on remaining disease free. This study draws on cumulative inequality theory to investigate whether experiencing childhood misfortune reduces the likelihood of remaining disease free over time.

Method

This study utilizes five waves of data from the Health and Retirement Study to test whether five domains of childhood misfortune predict being disease free at baseline (2004) and developing disease over time (2004-2012).

Results

Respondents reporting risky parental behaviors during childhood were less likely to be disease free at baseline and had an increased risk of disease onset over time, the latter driven by having a guardian who smoked in combination with more pack-years smoked in adulthood. Furthermore, we find that adult resources, that is wealth, help to mitigate the noxious effects of other misfortunes, notably poor socioeconomic conditions.

Discussion

Consistent with cumulative inequality theory, these findings reveal that experiencing multiple types of misfortune during childhood decreases the likelihood of remaining disease free in later life, but engaging in health behaviors, such as physical activity, can help to ameliorate some of the noxious effects of early misfortune.

Adverse Childhood Experiences and the Presence of Cancer Risk Factors in Adulthood: A Scoping Review of the Literature From 2005 to 2015

Exposure to Adverse Childhood Experiences (ACEs) is associated with a host of harmful outcomes, including increased risk for cancer. A scoping review was conducted to gain a better understanding of how ACEs have been studied in association with risk factors for cancer. This review includes 155 quantitative, peer-reviewed articles published between 2005 and 2015 that examined associations between ACEs and modifiable cancer risk factors, including alcohol, environmental carcinogens, chronic inflammation, sex hormones, immunosuppression, infectious agents, obesity, radiation, ultraviolet (UV) radiation, and tobacco, among U.S. adults. This review highlights the growing body of research connecting ACEs to cancer risk factors, particularly alcohol, obesity, and tobacco. Fewer studies investigated the links between ACEs and chronic inflammation or infectious agents. No included publications investigated associations between ACEs and environmental carcinogens, hormones, immunosuppression, radiation, or ultraviolet radiation. Mitigating the impact of ACEs may provide innovative ways to effect comprehensive, upstream cancer prevention.

Cumulative childhood adversity and adult cardiometabolic disease: A meta-analysis

OBJECTIVE

Adverse childhood experiences may be associated with cardiometabolic morbidity and mortality in adulthood. There is heterogeneity in this literature regarding the type of items in cumulative adversity indices, sample sizes, demographics, and covariates. The present review used quantitative meta-analysis to examine this association and potential moderators.

METHOD

Included studies had a measure of cumulative adversity (an index of at least 2 adverse childhood experiences from age 0 to 18) and a measure of cardiometabolic disease: cardiovascular disease (CVD) clinical outcomes (hypertension, coronary heart disease, ischemic heart disease, myocardial infarction, stroke, cerebrovascular disease) and metabolic outcomes (diabetes, metabolic syndrome) at age 18 or older. Given different interpretations of odds ratios (OR) versus hazard ratios (HR), effects were pooled separately. Overall, 9 HR studies (15 effects) based on 179,612 participants and 29 OR studies (62 effects) based on 247,393 participants were included.

RESULTS

On the basis of retrospectively assessed adversity, combined studies showed a significant estimated effect of cumulative childhood adversity on adult cardiometabolic disease (HR = 1.42, 95% CI [1.20, 1.67]; OR = 1.36 [1.27, 1.46]). Results varied somewhat by type of cardiometabolic disease, analytic strategy, and number and type of covariates.

CONCLUSIONS

The literature suggests that cumulative childhood adversity is modestly related to adult cardiometabolic disease, with effects somewhat stronger for CVD clinical outcomes. The absence of a consistent operational and conceptual definition of adversity and paucity of prospective designs temper the conclusions. It is time for further evaluation of the types and timing of childhood events that have maximal impact on adult cardiometabolic disease. (PsycINFO Database Record

Women's heart health at mid-life: what is the role of psychosocial stress?

BACKGROUND

Women in mid-life experience unique stressors, including transitions within their family roles, informal caregiving, job stress, and perceived discrimination. The impact of these stressors on cardiovascular health in women during mid-life is of growing interest in both the popular and scientific literature. The objective of this review is to summarize the recent literature on stress and cardiovascular health in mid-life women. We focus on stressors that are relevant to mid-life women, including social stress and discrimination, and long-term risk of CVD events and subclinical CVD measures.

METHODS

We systematically reviewed the literature published between January 2012 and April 2018 for studies examining stress in mid-life and either CVD endpoints or subclinical CVD outcomes. Eligible studies included at least one psychosocial stress exposure, a CVD or subclinical CVD outcome, and either included only female participants, reported sex-stratified analyses or tested for a sex*stress interaction.

RESULTS

We identified 37 studies published since 2012 that met our criteria and included women between the ages of 40 and 65, including 3 case-control studies, 15 cross-sectional studies, and 19 prospective cohort studies. Because clinical CVD events typically occur after age 65 in women, only 22 studies were available that evaluated stress and hard CVD events in samples with mid-life women. Results from these studies suggested an increased and significant risk of CVD due to stress. Of the 15 studies that included subclinical CVD outcomes, the majority showed that mid-life women experiencing greater levels of stress had more subclinical CVD, as indicated by carotid intima-media thickness, flow-mediated dilation and arterial stiffness; however, several studies reported null associations.

CONCLUSIONS

General life stress, including perceived stress and life events, in mid-life was significantly related to later-life CVD risk and mid-life subclinical CVD in the majority of studies published in the past six years. Job stress was inconsistently related to CVD risk in women, and fewer studies examined characteristics of other social roles, such as marriage, motherhood or caregiving. Perceived discrimination also was associated with CVD events and subclinical CVD in some samples of mid-life women. Further investigation into specific stressors relevant to women in mid-life, including caregiving and marital stress, are needed to understand the full extent to which life stress impacts CVD risk in mid-life women.

Childhood Misfortune, Personality, and Heart Attack: Does Personality Mediate Risk of Myocardial Infarction?

Objective

Previous research has revealed a link between childhood experiences and adult health, but the mechanisms underlying this relationship are less clear. To elucidate this relationship, we investigated the pathway from childhood misfortune to nonfatal myocardial infarction (MI) via individual differences in personality.

Method

Longitudinal data were drawn from the National Survey of Midlife Development in the United States, which sampled 3,032 men and women aged 25-74 years at baseline. Big 5 personality traits and multiple measures of childhood misfortune were used to assess whether personality mediated the effect of childhood misfortune on MI risk.

Results

A series of proportional hazards models revealed that neuroticism mediated the effect of additive childhood misfortune on adult MI risk.

Discussion

Childhood misfortune may be formative in the development of personality, which, subsequently, can be consequential to health. These findings highlight the salient roles of early-life experiences and personality to shape health and aging.

Does Early-Life Misfortune Increase the Likelihood of Psychotropic Medication Use in Later Life?

Life-course research has linked childhood experiences to adult mental illness, but most studies focus on anxiety or depressive symptoms, which may be transient. Therefore, this study investigates whether childhood misfortune is associated with taking psychotropic medication, a measure reflecting an underlying chronic mental disorder. Data are from three waves of a national survey of 2,999 U.S. men and women aged 25-74 years. Four domains of childhood misfortune (childhood socioeconomic status, family structure, child maltreatment, and poor health) are considered-specified as separate domains and a single additive measure-as key predictors of psychotropic medication use. Findings reveal an association between additive childhood misfortune and adult psychotropic medication use, net of adult risk factors. Psychotropic medication use is also more likely during the 20-year study for adults who experienced maltreatment and poor health during childhood. These results reveal the importance of early intervention to reduce consumption of psychotropic medications and associated costs.

Measuring Childhood Adversity in Life Course Cardiovascular Research: A Systematic Review

OBJECTIVE

Identifying the life course health effects of childhood adversity is a burgeoning area of research, particularly in relation to cardiovascular disease (CVD). However, adversity measurement varies widely across studies, which may hamper our ability to make comparisons across studies and identify mechanisms linking adversity to CVD. The purposes of this review are to summarize adversity measurement approaches in the context of CVD, identify gaps, and make recommendations for future research.

METHODS

PubMed and PsycINFO searches were conducted through June 2016. Studies were selected if CVD end point or predisease risk markers were investigated in association with a measure of childhood adversity. Forty-three studies were reviewed. A meta-analysis was not conducted because of the variation in exposures and outcomes assessed.

RESULTS

Adversity measurement was heterogeneous across studies. Metrics included different sets of adverse events, relational factors, and socioeconomic indicators. Thirty-seven percent measured childhood adversity prospectively, 23% examined a CVD end point, and 77% treated adversity as an unweighted summary score. Despite the heterogeneity in measurement, most studies found a positive association between childhood adversity and CVD risk, and the association seems to be dose-response.

CONCLUSIONS

The literature on childhood adversity and CVD would benefit from improving consistency of measurement, using weighted adversity composites, modeling adversity trajectories over time, and considering socioeconomic status as an antecedent factor instead of a component part of an adversity score. We suggest conceptual and analytic strategies to enhance, refine, and replicate the observed association between childhood adversity and CVD risk.

Childhood Maltreatment and Health Impact: The Examples of Cardiovascular Disease and Type 2 Diabetes Mellitus in Adults

Child maltreatment is associated with increased risk for an array of mental and physical health problems. We reviewed studies examining associations of child maltreatment, assessed either alone or in combination with other adversities, with cardiovascular disease (CVD) and Type 2 Diabetes. PubMed was searched for relevant studies until December, 2015. Forty publications met inclusion criteria. Consistent positive associations were noted across a range of childhood adversities. Child maltreatment was associated with CVD (myocardial infarction, stroke, ischemic heart disease, coronary heart disease) in 91.7% of studies, with diabetes in 88.2% of studies, and with blood pressure/hypertension in 61.5% of studies. Inclusion of mental disorders tended to attenuate associations. Sex-related differences were under-examined. Implications for future research and intervention efforts are discussed.

Panic Disorder Comorbidity with Medical Conditions and Treatment Implications

Panic disorder (PD) is unique among the anxiety disorders in that panic symptoms are primarily of a physical nature. Consequently, comorbidity with medical illness is significant. This review examines the association between PD and medical illness. We identify shared pathophysiological and psychological correlates and illustrate how physiological activation in panic sufferers underlies their symptom experience in the context of the fight-or-flight response and beyond a situation-specific response pattern. We then review evidence for bodily symptom perception accuracy in PD. Prevalence of comorbidity for PD and medical illness is presented, with a focus on respiratory and cardiovascular illness, irritable bowel syndrome, and diabetes, followed by an outline for potential pathways of a bidirectional association. We conclude by illustrating commonalities in mediating mechanistic pathways and moderating risk factors across medical illnesses, and we discuss implications for diagnosis and treatment of both types of conditions.

Alcohol's Collateral Damage: Childhood Exposure to Problem Drinkers and Subsequent Adult Mortality Risk

The importance of childhood circumstances, broadly defined, for shaping adult health and longevity is well-established. But the significance of one of the most prevalent childhood adversities-exposure to problem drinkers-has been understudied from a sociological perspective and remains poorly understood. We address this gap by drawing on cumulative inequality theory, using data from the 1988-2011 National Health Interview Survey-Linked Mortality Files, and estimating Cox proportional hazards models to examine the relationship between exposure to problem drinkers in childhood and adult mortality risk. Childhood exposure to problem drinkers is common (nearly 1 in 5 individuals were exposed) and elevates adult overall and cause-specific mortality risk. Compared to individuals who had not lived with a problem drinker during childhood, those who had done so suffered 17 percent higher risk of death (p<.001) over the follow-up period, net of age, sex, and race/ethnicity. We find compelling evidence that the duration, source, and intensity of exposure to problem drinkers in childhood contributes to inequality in adult mortality risk. Favorable socioeconomic status in adulthood does not ameliorate the consequences of childhood exposure to problem drinkers. The primary intervening mechanisms are risky behaviors, including adult drinking and smoking. The findings-which reveal that the influence of problem drinking is far-reaching and long-term-should inform policies to improve childhood circumstances, reduce detrimental effects of problem drinking, and increase life expectancy.

Explaining racial and ethnic inequalities in postpartum allostatic load: Results from a multisite study of low to middle income woment

BACKGROUND

Racial and ethnic inequalities in women's health are widely documented, but not for the postpartum period, and few studies examine whether neighborhood, psychosocial, and biological factors explain these gaps in women's health.

METHODS

Using prospective longitudinal data collected from 1766 low to middle income women between 2008 and 2012 by the Community Child Health Network (CCHN), we tested the extent to which adjustment for neighborhood, economic, psychological, and medical conditions following a birth explained differences between African American, Latina, and White women in an indicator of physiological dysregulation allostatic load (AL), at one year postpartum as measured by 10 biomarkers: Body Mass Index, Waist Hip Ratio, systolic and diastolic blood pressure, high sensitivity C-reactive protein, Hemoglobin A1c, high-density lipoprotein and cholesterol ratio, and diurnal cortisol.

RESULTS

Mean postpartum AL scores were 4.65 for African American, 4.57 for Latina and 3.86 for White women. Unadjusted regression estimates for high AL for African American women (with White as the reference) were 0.80 (SD = 0.11) and 0.53 (SD = 0.15) for Latina women. Adjustment for household poverty, neighborhood, stress, and resilience variables resulted in a reduction of 36% of the excess risk in high AL for African Americans versus Whites and 42% of the excess risk for Latinas compared to Whites.

CONCLUSIONS

Racial and ethnic inequalities in AL were accounted for largely by household poverty with additional contributions by psychological, economic, neighbourhood and medical variables. There remained a significant inequality between African American, and Latina women as compared to Whites even after adjustment for this set of variables. Future research into health inequalities among women should include a fuller consideration of the social determinants of health including employment, housing and prepregnancy medical conditions.

Early parenthood as a link between childhood disadvantage and adult heart problems: A gender-based approach

Drawing on conceptual models of critical periods, major life transitions, and life pathways, we proposed that the life-course features of parenthood are important, but understudied, mechanisms for explaining possibly gendered heart-health outcomes. Using three waves from the Midlife in the U.S. Study (MIDUS), we investigated (a) gender differences in the timing of the transition to parenthood as a pathway linking childhood SES disadvantage to onset of heart problems and (b) life-course factors (which vary by gender) that link the timing of the transition to parenthood to adult heart problems. We found that individuals who were disadvantaged in childhood were more likely to have their first child as teenagers or in early young adulthood. For women only, an early transition to parenthood partially explained the association between childhood disadvantage and onset of heart problems. Furthermore, women who had their first child at younger ages, particularly in their teens, had lower rates of college graduation, more financial difficulties, higher levels of depressive symptoms, and greater risk of smoking and obesity in midlife. These factors partially accounted for the association between early parenthood and onset of heart problems in later life. Our findings underscore the significance of the timing of the transition to parenthood in specifying the associations between childhood disadvantage and adult heart problems. Various factors are involved, including low adult SES, psychological distress, and unhealthy lifestyles.

Experiences of violence across life course and its effects on mobility among participants in the International Mobility in Aging Study

BACKGROUND

Life course exposure to violence may lead to disability in old age. We examine associations and pathways between life course violence and mobility disability in older participants of the International Mobility in Aging Study (IMIAS).

METHODS

A cross-sectional study using IMIAS 2012 baseline. Men and women aged 65-74 years were recruited at 5 cities (n=1995): Kingston and Saint-Hyacinthe (Canada), Tirana (Albania), Manizales (Colombia) and Natal (Brazil). Mobility was assessed by the Short Physical Performance Battery (SPPB) and by 2 questions on difficulty in walking and climbing stairs. Childhood physical abuse history and the HITS instrument were used to gather information on childhood exposure to violence and violence by intimate partners or family members. Multivariate logistic regression and mediation analysis models were constructed to explore the significance of direct and indirect effects of violence on mobility. Interaction effects of gender on violence and on each of the mediators were tested.

RESULTS

Experiences of physical violence at any point of life were associated with mobility disability (defined as SPPB<8 or limitation in walking/climbing stairs) while psychological violence was not. Chronic conditions, C reactive protein, physical activity and depression mediated the effect of childhood exposure to violence on both mobility outcomes. Chronic conditions and depression were pathways between family and partner violence and both mobility outcomes. Physical activity was a significant pathway linking family violence to mobility. Gender interactions were not significant.

CONCLUSIONS

Our results provide evidence for the detrimental effects of life course exposure to violence on mobility in later life.

Chronic Disease at Midlife: Do Parent-child Bonds Modify the Effect of Childhood SES?

Childhood socioeconomic status (SES) often is associated with physical health even decades later. However, parent-child emotional bonds during childhood may modify the importance of childhood SES to emergent health inequalities across the life course. Drawing on national data on middle-aged adults (1995 and 2005 National Survey of Midlife Development in the United States; MIDUS; Ns = 2,746 and 1,632), I find that compromised parent-child bonds eliminate the association between childhood SES and midlife disease. Longitudinal models of incident disease across one decade show that childhood abuse in particular continues to undermine the health protection associated with childhood SES. When childhood SES is moderate to high, compromised parent-child bonds lead to no predicted health benefits from childhood SES. In total, these findings direct attention to parent-child bonds as social-psychological levers for the transmission of class-based health advantages.

The role of adverse childhood experiences in cardiovascular disease risk: a review with emphasis on plausible mechanisms

Childhood adversity, characterized by abuse, neglect, and household dysfunction, is a problem that exerts a significant impact on individuals, families, and society. Growing evidence suggests that adverse childhood experiences (ACEs) are associated with health decline in adulthood, including cardiovascular disease (CVD). In the current review, we first provide an overview of the association between ACEs and CVD risk, with updates on the latest epidemiological evidence. Second, we briefly review plausible pathways by which ACEs could influence CVD risk, including traditional risk factors and novel mechanisms. Finally, we highlight the potential implications of ACEs in clinical and public health. Information gleaned from this review should help physicians and researchers in better understanding potential long-term consequences of ACEs and considering adapting current strategies in treatment or intervention for patients with ACEs.

The Relationship between Allostatic Load and Psychosocial Characteristics among Women Veterans

BACKGROUND

Allostatic load (AL) is a novel perspective for examining the damaging effects of stress on health and disease. Women veterans represent an understudied yet vulnerable subgroup of women with increased reports of traumatic stressors across their lifespan. AL has not been examined in this group. This study hypothesized that reports of sexual assault in childhood, civilian life, or in the military by women veterans was associated with AL and selected psychosocial measures. We also hypothesized that AL scores are positively associated with psychosocial characteristics.

METHODS

Using a cross-sectional design, psychosocial and physiological data were obtained from women veterans (n = 81; 24-70 years old).

FINDINGS

The AL score was 3.03 ± 2.36 and positively associated with age (p = .001). There was a trend for higher pain scores for women with an AL score of 2 or greater compared with those with an AL score of less than 2. There were significant differences in the Somatic Subscale of the Center for Epidemiological Depression Scale among the sexual assault categories with increasing scores among women reporting sexual assault in childhood, military, and civilian life (p = .049). The scores of the Profile of Mood States Depression/Dejection Subscale (p = .015), the Post-Traumatic Checklist- Military (p = .002), and the Pain Outcome Questionnaire (p = .001) were associated with sexual assault categories in a dose-response fashion.

CONCLUSIONS

AL was associated positively with age, and sexual assault categories were associated with increased somatization, depressed mood, posttraumatic symptoms and pain. Assessing both AL and sexual trauma are critical for preventing and managing the subsequent negative health consequences among women veterans.

Clarifying Associations between Childhood Adversity, Social Support, Behavioral Factors, and Mental Health, Health, and Well-Being in Adulthood: A Population-Based Study

Previous studies have shown that socio-demographic factors, childhood socioeconomic status (CSES), childhood traumatic experiences (CTEs), social support and behavioral factors are associated with health and well-being in adulthood. However, the relative importance of these factors for mental health, health, and well-being has not been studied. Moreover, the mechanisms by which CTEs affect mental health, health, and well-being in adulthood are not clear. Using data from a representative sample (n = 12,981) of the adult population in Tromsø, Norway, this study examines (i) the relative contribution of structural conditions (gender, age, CSES, psychological abuse, physical abuse, and substance abuse distress) to social support and behavioral factors in adulthood; (ii) the relative contribution of socio-demographic factors, CSES, CTEs, social support, and behavioral factors to three multi-item instruments of mental health (SCL-10), health (EQ-5D), and subjective well-being (SWLS) in adulthood; (iii) the impact of CTEs on mental health, health, and well-being in adulthood, and; (iv) the mediating role of adult social support and behavioral factors in these associations. Instrumental support (24.16%, p < 0.001) explained most of the variation in mental health, while gender (21.32%, p < 0.001) explained most of the variation in health, and emotional support (23.34%, p < 0.001) explained most of the variation in well-being. Psychological abuse was relatively more important for mental health (12.13%), health (7.01%), and well-being (9.09%), as compared to physical abuse, and substance abuse distress. The subjective assessment of childhood financial conditions was relatively more important for mental health (6.02%), health (10.60%), and well-being (20.60%), as compared to mother's and father's education. CTEs were relatively more important for mental health, while, CSES was relatively more important for health and well-being. Respondents exposed to all three types of CTEs had a more than two-fold increased risk of being mentally unhealthy (RR Total Effect = 2.75, 95% CI: 2.19-3.10), an 89% increased risk of being unhealthy (RR Total Effect = 1.89, 95% CI: 1.47-1.99), and a 42% increased risk of having a low level of well-being in adulthood (RR Total Effect = 1.42, 95% CI: 1.29-1.52). Social support and behavioral factors mediate 11-18% (p < 0.01) of these effects. The study advances the theoretical understanding of how CTEs influence adult mental health, health, and well-being.

Childhood Disadvantage and Health Problems in Middle and Later Life: Early Imprints on Physical Health?

Drawing from cumulative inequality theory, we examine the relationship between childhood disadvantage and health problems in adulthood. Using two waves of data from Midlife Development in the United States, we investigate whether childhood disadvantage is associated with adult disadvantage, including fewer social resources, and the effect of lifelong disadvantage on health problems measured at the baseline survey and a 10-year follow-up. Findings reveal that childhood socioeconomic disadvantage and frequent abuse by parents are generally associated with fewer adult social resources and more lifestyle risks. Health problems, in turn, are affected by childhood disadvantage and by lifestyle risks, especially smoking and obesity. Not only was early disadvantage related to health problems at the baseline survey, but childhood socioeconomic disadvantage and frequent abuse also were related to the development of new health problems at the follow-up survey. These findings reveal the imprint of early disadvantage on health decades later and suggest greater attention to resources, even during midlife, can interrupt the chain of risks.
