Childhood trauma and adulthood physical health in Mexico

Adverse childhood experiences: Examining latent classes and associations with physical, psychological, and risk-related outcomes in adulthood

BACKGROUND

Adverse childhood experiences (ACEs) are a public health crisis, affecting nearly half of children in the United States. Long-term effects of ACEs on psychological well-being, engagement in risk behaviors, and physical health have been observed. Moreover, many individuals exposed to ACEs are also affected by an accumulation of stressors due to broader structural inequities.

OBJECTIVE

The current study examined heterogeneity in patterns of ACEs, explored how these patterns varied based on race/ethnicity, biological sex, and socioeconomic status, and assessed how ACE patterns were associated with physical health, mental health, and risk-related outcomes in adulthood.

PARTICIPANTS

Drawing on the Add Health dataset, survey data from Waves I, III, IV (n = 12,288) were analyzed. Mean age of participants was 28.3 (SD = 1.9), more than half were female (54.4%), and a little less than half identified as youth of color (46.7%).

METHOD

Multigroup latent class analysis explored heterogeneity in ACE exposure and variations based on structural inequities. Latent class regression assessed associations between ACE classes and outcomes.

RESULTS

A four-class solution was identified. Class sizes and latent structures differed by biological sex. Among males and females, the low adversity class had more positive physical health, mental health, and risk-related outcomes compared to all classes, while the childhood maltreatment and high adversity/community violence classes engaged in more risk-related behaviors. Very small to medium effects were observed.

CONCLUSION

Findings highlight the importance of examining heterogeneity in ACE exposure, and how patterns of ACEs may differentially affect outcomes in adulthood.

State-of-the-Science Review of Non-Chemical Stressors Found in a Child's Social Environment

Background: Children are exposed to chemical and non-chemical stressors from their built, natural, and social environments. Research is needed to advance our scientific understanding of non-chemical stressors, evaluate how they alter the biological response to a chemical stressor, and determine how they impact children’s health and well-being. To do this, we conducted a state-of-the-science review of non-chemical stressors found in a child’s social environment. Methods: Studies eligible for inclusion in this review were identified through a search of the peer-reviewed literature using PubMed and PsycINFO. Combinations of words associated with non-chemical stressors and children were used to form search strings. Filters were used to limit the search to studies published in peer-reviewed journals from 2000–2016 and written in English. Publications found using the search strings and filters went through two rounds of screening. Results: A total of 146 studies met the inclusion criteria. From these studies, 245 non-chemical stressors were evaluated. The non-chemical stressors were then organized into 13 general topic areas: acculturation, adverse childhood experiences, economic, education, family dynamics, food, greenspace, neighborhood, social, stress, urbanicity, violence, and other. Additional information on health outcomes, studies evaluating both chemical and non-chemical stressors, and animal studies are provided. This review provides evidence that non-chemical stressors found in a child’s social environment do influence their health and well-being in both beneficial (e.g., salutatory effects of greenspace and social support) and adverse (e.g., poor relationships between health and selected non-chemical stressors such as economics, educational attainment, exposure to violence, stress) ways. Conclusions: This literature review identified a paucity of studies addressing the combined effects of chemical and non-chemical stressors and children’s health and well-being. This literature review was further complicated by inconsistencies in terminology, methodologies, and the value of non-chemical stressor research in different scientific disciplines. Despite these limitations, this review showed the importance of considering non-chemical stressors from a child’s social environment when addressing children’s environmental health considerations.

Differential activation of the renin-angiotensin-aldosterone-system in response to childhood and adulthood trauma

OBJECTIVE

Previous evidence suggested lasting and cumulative effects of traumatization on the renin-angiotensin-aldosterone-system (RAAS). However, it is unclear whether traumas during childhood and those experienced in adulthood differentially impact the RAAS. In this study, we sought to investigate main and putative interactive effects of childhood and adulthood trauma on RAAS functioning.

METHODS

Plasma concentrations of renin and aldosterone were measured in a general population sample (n = 2016). Childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ), adulthood trauma was measured using the PTSD module of the Structured Clinical Interview of the DSM-IV. Linear regression models were calculated to assess the relations between childhood or adulthood traumatization with renin and aldosterone concentrations.

RESULTS

Exposure to (ß = 0.094; p = 0.01), severity of childhood trauma (ß = 0.004; p = 0.01) were associated with increased aldosterone, but not renin levels. Results were carried by all dimensions of abuse, while childhood neglect was not associated with altered RAAS activity. In contrast, adulthood traumas (ß = 0.113; p < 0.01) were significantly associated with increased renin concentrations. Subjects with PTSD (renin: ß = 0.345; p = 0.01; aldosterone: ß = 0.232; p = 0.04) and those who had been exposed to both childhood and adulthood trauma showed increases in renin (ß = 0.180; p < 0.01) and aldosterone (ß = 0.340; p < 0.01) levels.

DISCUSSION

These findings indicate that trauma is associated with differential alterations of the RAAS depending on the time of traumatization. Moreover, exposure to childhood or adulthood trauma may act synergistically on the RAAS, resulting in severe dysregulation of the RAAS. The results contribute to explain associations between trauma and enhanced risk for physical disease.

Associations of trauma exposure and post-traumatic stress disorder with the activity of the renin-angiotensin-aldosterone-system in the general population

BACKGROUND

Previous studies suggested that exposure to traumatic events during childhood and adulthood and post-traumatic stress disorder (PTSD) are associated with a dysregulation of different neuroendocrine systems. However, the activity of the renin-angiotensin-aldosterone-system (RAAS) in relation to trauma/PTSD has been largely neglected.

METHODS

Traumatization, PTSD, and plasma concentrations of renin and aldosterone were measured in 3092 individuals from the general population. Subgroups according to the status of traumatization ('without trauma'; 'trauma, without PTSD', 'PTSD') were formed and compared regarding renin and aldosterone concentrations. Additionally, we calculated the associations between the number of traumata, renin, and aldosterone concentrations. Finally, associations of PTSD with renin/aldosterone levels were controlled for the number of traumata ('trauma load').

RESULTS

Levels of renin, but not aldosterone, were increased in traumatized persons without PTSD (p = 0.02) and, even stronger, with PTSD (p &lt; 0.01). Moreover, we found a dose-response relation between the number of traumata and renin levels (β = 0.065; p &lt; 0.001). Regression analyses showed PTSD as a significant predictor of renin (β = 0.38; p &lt; 0.01). This effect was only slightly attenuated when controlled for trauma load (β = 0.32; p &lt; 0.01).

CONCLUSIONS

Our results suggest that traumatization has lasting and cumulative effects on RAAS activity. Finding elevated renin levels in PTSD independent from trauma load supports the concept of PTSD as a disorder with specific neuroendocrine characteristics. Alternatively, elevated renin levels in traumatized persons may increase the risk for developing PTSD. Our findings contribute to explain the relationship between traumatic stress/PTSD and physical disorders.

Childhood adversity and depressive symptoms following retirement in the Gazel cohort

BACKGROUND

Only a few studies have examined whether specific moderators may impact the magnitude of the relationship between retirement and depression. The aim of this study was to examine the potential moderating role of adverse childhood life events (ACLE) on changes in depressive symptoms following retirement in the GAZEL cohort.

METHODS

9242 participants, followed up since 1989, completed the Center of Epidemiologic Studies Depression scale (CESD) every three years and were asked in 2004 to answer an ACLE questionnaire. Subjects were classed according to 6 clusters by Two-Step Cluster Analysis (no ACLE: cluster 1; increasing material deprivation: clusters 2 to 4; history of early separation: cluster 5 and history of conflicts or violence: cluster 6), and then stratified for sex. Analyses were based on general linear models with the CESD variation between, before and after retirement as dependent variable. All results were adjusted according to age, marital status, occupational status, alcohol consumption, self-rated health and CESD score before retirement.

RESULTS

The association between exposure to ACLE and changes in depressive symptoms following retirement was significant in both men (F = 6.929; p < 0.001; eta(2) = 0.005) and women (F = 6.890; p < 0.001; eta(2) = 0.016). Exposure to early separation or history of conflicts or violence during childhood was associated with less improvement in both men and women, whereas early exposure to material deprivation only affected results in men.

CONCLUSIONS

Programs aimed at facilitating retirement transition may focus on subjects at risk of not experiencing the expected benefits of retirement, which is the case for those with a history of ACLE.

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 Traumatic Experiences, Anxiety, and Depression Levels in Fibromyalgia and Rheumatoid Arthritis

INTRODUCTION

The close relationship between chronic pain, anxiety, depression, and childhood traumatic experiences is well known. The aim of this study is to investigate childhood traumatic experiences, anxiety, and depression levels in patients with fibromyalgia and rheumatoid arthritis, which are diseases that cause chronic pain.

METHOD

A total of 30 patients with fibromyalgia, 30 patients with rheumatoid arthritis, and 30 healthy controls, matched with patients with respect to gender, age, and education, were included in the study (90 participants in total). All participants were given a form for sociodemographic characteristics, the Childhood Trauma Questionnaire (CTQ), and Hospital Anxiety and Depression Scale (HAD). Patients were also asked to complete a numeric pain scale (NPS).

RESULTS

Patients with fibromyalgia reported significantly higher scores for CTQ emotional abuse and HAD depression compared with healthy controls. Patients with fibromyalgia reported significantly higher scores for HAD anxiety than both healthy controls and patients with rheumatoid arthritis. Patients with rheumatoid arthritis reported significantly higher scores for CTQ emotional abuse and HAD depression compared with healthy controls. Pain scores of patients with fibromyalgia were higher than in patients with rheumatoid arthritis. Participants who had scores over the threshold on HAD anxiety and depression had significantly higher scores on CTQ sexual abuse.

CONCLUSION

Both patients with fibromyalgia and patients with rheumatoid arthritis have high levels of childhood traumatic experiences and depression. Patients with pain-related disorders should be examined for childhood traumatic experiences, anxiety, and depression for better treatment outcomes.

Posttraumatic Stress and Meaning Making in Mexico City

Mexico City, established in 1524, is Mexico’s most important educational, financial and cultural centre. As is typical of large metropolitan cities, Mexico City has its share of crime, violence and poverty. It also has a history of natural disasters, particularly large-scale earthquakes. There is a lack of research on the impacts and correlates of chronic exposure to trauma in developing societies such as Mexico City. Particularly, a dearth of research that examines the relationship between exposure to trauma and posttraumatic growth in these populations exists. Recently, the Association of Trauma Outreach and Prevention (ATOP) organised a humanitarian mission to Mexico City to assess posttraumatic symptomatology and identify factors that contributed to meaning making and posttraumatic growth, including socio-demographic variables. The results demonstrated that age and marital status were associated with traumatic stress symptomatology and the ability to find meaning in trauma and purpose in one’s life. Inconsistent with previous research, there were no differential associations in symptomatology or posttraumatic growth on the basis of gender. Of note, the results suggested that individuals who had offered support to others during a traumatic event were currently experiencing lower levels of posttraumatic stress and an increased ability to find meaning in the trauma.

DSM-5 PTSD's symptom dimensions and relations with major depression's symptom dimensions in a primary care sample

Existing literature indicates significant comorbidity between posttraumatic stress disorder (PTSD) and major depression. We examined whether PTSD's dysphoria and mood/cognitions factors, conceptualized by the empirically supported four-factor DSM-5 PTSD models, account for PTSD's inherent relationship with depression. We hypothesized that depression's somatic and non-somatic factors would be more related to PTSD's dysphoria and mood/cognitions factors than other PTSD model factors. Further, we hypothesized that PTSD's arousal would significantly mediate relations between PTSD's dysphoria and somatic/non-somatic depression. Using 181 trauma-exposed primary care patients, confirmatory factor analyses (CFA) indicated a well-fitting DSM-5 PTSD dysphoria model, DSM-5 numbing model and two-factor depression model. Both somatic and non-somatic depression factors were more related to PTSD's dysphoria and mood/cognitions factors than to re-experiencing and avoidance factors; non-somatic depression was more related to PTSD's dysphoria than PTSD's arousal factor. PTSD's arousal did not mediate the relationship between PTSD's dysphoria and somatic/non-somatic depression. Implications are discussed.

Trauma exposure and health: the role of depressive and hyperarousal symptoms

Posttraumatic stress disorder (PTSD) and depressive symptoms have been theorized to mediate the relationship between trauma exposure and physical health symptoms. Although empirical evidence supports this premise, studies conducted to date have employed statistical mediation analyses that are now broadly criticized. Furthermore, the mediating roles of both PTSD and depressive symptoms have seldom been examined concurrently, and it remains unclear which PTSD symptom clusters uniquely mediate this relationship. The aim of the present study was to examine the mediating role of reexperiencing, avoidance/numbing, hyperarousal, and depressive symptoms in the relationship between trauma exposure and physical health symptoms. Participants were 516 Spanish female undergraduate students. Physical health symptoms were compared between those who reported trauma exposure (n = 266) and those who did not (n = 250). Data from trauma-exposed participants were analyzed using regression models with bootstrapping to test mediation. Results of the analyses showed that the trauma-exposed group reported significantly more physical health symptoms (r(2) = .035). Hyperarousal and depressive symptoms uniquely mediated the relationship between trauma exposure and physical health symptoms. Our findings clarify some of the mechanisms by which negative health consequences occur subsequent to trauma exposure.

Physical health status of female veterans: contributions of sex partnership and in-military rape

OBJECTIVE

The aim of this study was to determine whether current physical health status in female veterans is associated with rape during military service and same-sex partnership.

METHODS

Retrospective computer-assisted telephone interviews of 1004 Midwestern US female veterans identified from Veterans Affairs electronic records were conducted. Data included rape history including rape in military, sex partnership history, demographics, and medical history including chronic pain, mental health (depression and posttraumatic stress disorder [PTSD]), and the physical health component of the Short-Form 12-item interview (PCS-12).

RESULTS

Physical health in this sample was lower than norm values [PCS-12: mean (standard deviation) = 43 [12]; norm: mean (standard deviation) = 50 [10]). Fifty-one percent of the participants reported rape in their lifetime, 25% reported rape in military, 11% reported history of women as sex partners, and 71% reported history of chronic pain. Multiple regression analysis indicated that physical health (PCS-12) was associated with chronic pain history (β = -.40, p < .001), rape in military (β = -.09, p = .002), and current PTSD (β = .07, p = .03), adjusting for demographic data. Mediational analysis indicated that chronic pain history significantly mediated relationships of women who have sex with women, childhood rape, PTSD, depression, and current substance use disorder with PCS-12.

CONCLUSIONS

Both rape and sex partnership are adversely associated with lower physical functioning in female veterans. Clinicians evaluating the physical health of this population should therefore consider obtaining detailed sexual histories, and a multidisciplinary team is needed to address mental health issues in female veterans.

Interpersonal abuse and depression among mexican immigrant women with type 2 diabetes

Evidence for a bi-directional relationship of depression and type 2 diabetes suggests that social distress plays a role in depression among people with diabetes. In this study, we examine the relationship between subjective distress and depression in 121 first- and second-generation Mexican immigrant women seeking diabetes care at a safety-net hospital in Chicago. We used a mixed-methods approach including narrative interview, survey, and finger-stick blood HbA1c data. Using grounded theory analysis, we identified seven life stressors from narrative interviews: interpersonal abuse, stress related to health, family, neighborhood violence, immigration status, and work, and feeling socially detached. Women reported unusually high rates of interpersonal abuse (65%) and disaggregated physical abuse (54%) and sexual abuse (23%). We evaluated depression using CES-D cut-off points of 16 and 24 and assessed rates to be 49 and 34%, respectively. We found that interpersonal abuse was a significant predictor of depression (CESD ≥ 24) in bivariate (OR 3.97; 95% CI 1.58-10.0) and multivariate (OR 5.51; 95% CI 1.85, 16.4) logistic regression analyses. These findings suggest that interpersonal abuse functions as an important contributor to depression among low-income Mexican immigrant women and should be recognized and addressed in diabetes care.

Acculturation, childhood trauma and the cortisol awakening response in Mexican-American adults

Exposure to chronic and traumatic stress has been associated with the dysregulation of crucial stress response systems. Acculturation has been associated with unique forms of chronic psychosocial stress. The purpose of this study was to examine the effects of exposure to early traumatic stress and acculturation on dysregulation of the cortisol awakening response (CAR) in Mexican-American adults. Salivary cortisol samples were collected at awakening and 30, 45, and 60 min thereafter, on two consecutive weekdays from 59 healthy Mexican-American adult males (26) and females (33), ages 18-38 years. Participants were assessed for level of acculturation and exposure to early trauma. Data were analyzed using a mixed effects regression model with repeated measures at four time points. Mixed effects regression results indicated a significant Early Trauma x Time interaction (p=.0029) and a significant Acculturation x Time interaction (p=.0015), after controlling for age and sex. Subsequent analyses of the interaction of Trauma x Acculturation x Time showed that more than minimal exposure to either risk factor was associated with attenuation of the awakening cortisol response (p=.0002). Higher levels of acculturation with greater Anglo-orientation were associated with attenuation of the CAR in Mexican-American adults. Both moderate and higher levels of exposure to early trauma were associated with an attenuated CAR. However, greater exposure to both risk factors was only incrementally worse than exposure to either one.

Childhood life events and psychological symptoms in adult survivors of the 2004 tsunami

BACKGROUND

Negative life events in childhood have an adverse influence on adult psychological health, and increase vulnerability to subsequent potential traumas. It remains unclear whether this is also true in the case of disasters.

AIM

This study investigates whether the experience of negative life events in childhood and adolescence was associated with psychological symptoms in groups of Swedish survivors with different types of exposure to the tsunami.

METHODS

1505 survivors from Stockholm responded to a questionnaire on psychological distress, which was sent by post 14 months after the 2004 Indian Ocean tsunami. Psychological distress was measured by General Health Questionnaire-12 and suicidal ideation, and post-traumatic stress was measured by Impact of Event Scale-Revised. Life events prior to age 16 were collected and categorized under the indices accident, violence, loss and interpersonal events. Exposure to the tsunami was categorized in different types, and controlled for in the analyses.

RESULTS

With the adjustment for confounders, significant odds ratios were found for all indices on at least one outcome measure, despite the powerful effect of the tsunami. We could not discern any distinct difference in the distribution of the tendency to report the different outcomes depending on types of prior life events.

CONCLUSIONS

The implication of the study is that, for adult survivors of disaster, the reporting of adverse life events from childhood may influence future decisions regarding therapy.
