Effects of childhood abuse on adult obesity: a systematic review and meta-analysis

Metabolic syndrome after childhood trauma: a 9-year longitudinal analysis

BACKGROUND

Childhood trauma (CT) has been cross-sectionally associated with metabolic syndrome (MetS), a group of biological risk factors for cardiometabolic disease. Longitudinal studies, while rare, would clarify the development of cardiometabolic dysregulations over time. Therefore, we longitudinally investigated the association of CT with the 9-year course of MetS components.

METHODS

Participants (N = 2958) from the Netherlands Study of Depression and Anxiety were assessed four times across 9 years. The CT interview retrospectively assessed childhood emotional neglect and physical, emotional, and sexual abuse. Metabolic outcomes encompassed continuous MetS components (waist circumference, triglycerides, high-density lipoprotein [HDL] cholesterol, blood pressure [BP], and glucose) and count of clinically elevated MetS components. Mixed-effects models estimated sociodemographic- and lifestyle-adjusted longitudinal associations of CT with metabolic outcomes over time. Time interactions evaluated change in these associations.

RESULTS

CT was reported by 49% of participants. CT was consistently associated with increased waist (b = 0.32, s.e. = 0.10, p = 0.001), glucose (b = 0.02, s.e. = 0.01, p < 0.001), and count of MetS components (b = 0.04, s.e. = 0.01, p < 0.001); and decreased HDL cholesterol (b = -0.01, s.e.<0.01, p = .020) and systolic BP (b = -0.33, s.e. = 0.13, p = 0.010). These associations were mainly driven by severe CT and unaffected by lifestyle. Only systolic BP showed a CT-by-time interaction, where CT was associated with lower systolic BP initially and with higher systolic BP at the last follow-up.

CONCLUSIONS

Over time, adults with CT have overall persistent poorer metabolic outcomes than their non-maltreated peers. Individuals with CT have an increased risk for cardiometabolic disease and may benefit from monitoring and early interventions targeting metabolism.

Traumatic Life Events, Violence, and Obesity: A Cross-Sectional Study from 408 Patients Enrolled in a Bariatric Surgery Program

INTRODUCTION

Obesity is a chronic disease that increases cardiovascular and metabolic morbidity and mortality, decreases quality of life, and increases health care costs. While the role of lifestyle behavioral factors in the development of obesity is well established, the role of traumatic life events, including violence, is unclear. The purpose of this study was to describe situations of traumatic life events reported by patients undergoing a bariatric surgery program, with a particular focus on sexual violence and its clinical correlates.

METHODS

In this cross-sectional study, patients with grade II or III obesity, admitted to our digestive surgery department for bariatric surgery from August 01, 2019, to December 31, 2020, underwent a structured interview by a trained psychologist to describe the history of traumatic life events self-reported by the patients. The primary endpoint was the presence of a history of sexual violence (SV). Multivariate logistic regressions were applied to identify independent risk factors for SV.

RESULTS

Of the 408 patients interviewed, 87.1% reported at least one traumatic life event and 33.1% reported having had an SV in the past. Female gender (aOR = 7.44, 95% confidence interval: 3.85-15.73; p < 0.001) and higher body mass index (1.05, 1.02-1.08; p = 0.002) were associated with an increased risk of SV. Male gender was associated with a higher risk of difficulties including sports cessation, depression, and work-related distress.

CONCLUSION

In the context of obesity, psychosocial trauma is characterized by a high frequency and several gender specificities that must be taken into account in the management of these patients.

Hypertension and other vascular risk factors in patients with functional seizures

OBJECTIVE

Recent literature has suggested that functional seizures are associated with an elevated risk for vascular disease and mortality. We investigated the prevalence of risk factors for vascular disease in patients who were admitted to the epilepsy monitoring unit.

METHODS

Patients who were admitted to the epilepsy monitoring unit and received a definitive diagnosis of either functional seizures or epilepsy were identified. Data collected included demographic, clinical characteristics, medication list, comorbidities, and scheduled blood pressure measurements that occurred every 12 h during the admission. The mean blood pressures were calculated and if they were above the American College of Cardiology and the American Heart Association guideline cutoff of 130/80 mm Hg or the patient had a documented history of hypertension the patient was counted as having the condition. A multiple logistic regression model was developed to evaluate the independent association of the patient's diagnosis (i.e., epilepsy or functional seizures) and vascular risk factors that controlled for the number of blood pressure measurements, age, sex, and if the patient was taking antihypertensive medications.

RESULTS

270 patients were included in this study of which 147 patients had epilepsy and 123 had functional seizures. Among those with functional seizures, 57.72 % had either a history of hypertension or a mean blood pressure above 130/80 compared to 38.78 % of those with epilepsy (p = 0.0022). In addition, 30.89 % of functional seizures patients had hyperlipidemia and 63.41 % were obese. The logistic regression model indicated that functional seizures were independently associated with high blood pressure (OR: 2.47, 95 % CI 1.10-5.69), hyperlipidemia (OR: 3.38, 95 % CI 1.35-8.86), and obesity (OR: 4.25, 95 % CI 2.22-8.36) compared to those with epilepsy. There was no significant difference in the prevalence of diabetes (OR: 0.81, 95 % CI 0.24-2.77) or current tobacco use (OR: 1.04, 95 % CI 0.48-2.25) between the groups.

SIGNIFICANCE

Patients with functional seizures had an elevated prevalence of several vascular risk factors. These findings may partially account for complications associated with functional seizures and have implications related to their pathophysiology.

Sex-specific associations of childhood maltreatment with obesity-related traits - The Study of Health in Pomerania (SHIP)

BACKGROUND

Child maltreatment (CM) is linked to obesity in adulthood. However, sex-differences and direct measurements of body fat have previously been insufficiently considered in this context.

OBJECTIVE

To assess sex-specific associations of CM with anthropometric markers of overweight/obesity and direct measures of body fat.

PARTICIPANTS AND SETTING

Analyses were conducted in 4006 adults from a population-based cohort in Northeastern Germany (SHIP-TREND-0).

METHODS

CM was assessed using the Childhood Trauma Questionnaire (CTQ). Obesity-related traits included anthropometric indicators (i.e., height, weight, body mass index [BMI], waist [WC] and hip circumference [HC], waist-to-hip ratio [WHR], waist-to-height ratio [WHtR]), fat mass (FM) and fat-free mass (FFM) derived from bioelectrical impedance analysis (BIA), and subcutaneous (SAT) and visceral adipose tissue (VAT) ascertained using magnetic resonance imaging (MRI). Sex-stratified linear regression models predicting obesity-related traits from total CTQ scores were adjusted for age and education. Exploratory analyses investigated effects of CTQ subscales on obesity-related traits.

RESULTS

In men, CM was positively associated with WHtR (β = 0.04; p = .030) and VAT (β = 0.02; p = .031) and inversely with body height (β = -0.05; p = .010). In women, CM-exposure was positively associated with body weight (β = 0.07; p = .018), BMI (β = 0.03; p = .013), WC (β = 0.07; p = .005), HC (β = 0.05; p = .046), WHR (β = 0.03; p = .015), WHtR (β = 0.04; p = .006), FM (β = 0.04; p = .006), and SAT (β = 0.06; p = .041). In both sexes, effects were mainly driven by exposure to emotional and physical abuse.

CONCLUSIONS

Results suggest that associations between CM-exposure and obesity-related traits in adulthood are primarily present in women. This may have implications for sex-specific obesity-related cardiometabolic risk after CM.

Multiple mediation of the association between childhood emotional abuse and adult obesity by anxiety and bulimia - a sample from bariatric surgery candidates and healthy controls

Bulimia, which means a person has episodes of eating a very large amount of food (bingeing) during which the person feels a loss of control over their eating, is the most primitive reason for being overweight and obese. The extended literature has indicated that childhood emotional abuse has a close relationship with adverse mood states, bulimia, and obesity. To comprehensively understand the potential links among these factors, we evaluated a multiple mediation model in which anxiety/depression and bulimia were mediators between childhood emotional abuse and body mass index (BMI). A set of self-report questionnaires, including the Childhood Trauma Questionnaire (CTQ), Beck Anxiety Inventory, Beck Depression Inventory (BDI), and Eating Disorder Inventory (EDI), was sent out. Clinical data from 37 obese patients (age: 29.65 ± 5.35, body mass index (BMI): 37.59 ± 6.34) and 37 demographically well-matched healthy people with normal body weight (age: 31.35 ± 10.84, BMI: 22.16 ± 3.69) were included in the investigation. We first performed an independent t-test to compare all scales or subscale scores between the two groups. Then, we conducted Pearson correlation analysis to test every two variables' pairwise correlation. Finally, multiple mediation analysis was performed with BMI as the outcome variable, and childhood emotional abuse as the predictive variable. Pairs of anxiety, bulimia, and depression, bulimia were selected as the mediating variables in different multiple mediation models separately. The results show that the obese group reported higher childhood emotional abuse (t = 2.157, p = 0.034), worse mood state (anxiety: t = 5.466, p < 0.001; depression: t = 2.220, p = 0.030), and higher bulimia (t = 3.400, p = 0.001) than the healthy control group. Positive correlations were found in every pairwise combination of BMI, childhood emotional abuse, anxiety, and bulimia. Multiple mediation analyses indicate that childhood emotional abuse is positively linked to BMI (β = 1.312, 95% CI = 0.482-2.141). The model using anxiety and bulimia as the multiple mediating variables is attested to play roles in the relationship between childhood emotional abuse and obesity (indirect effect = 0.739, 95% CI = 0.261-1.608, 56.33% of the total effect). These findings confirm that childhood emotional abuse contributes to adulthood obesity through the multiple mediating effects of anxiety and bulimia. The present study adds another potential model to facilitate our understanding of the eating psychopathology of obesity.

The contribution of childhood maltreatment to the incidence of heavy cannabis use in Iran (IRNS-CCI): A multicenter, matched-pairs, nested, case-control study

BACKGROUND

Previous studies have shown the role of the interaction between the endocannabinoid system (ECS) and life's adversities in the formation of addiction, including alcohol abuse.

OBJECTIVE

Our objective was to identify childhood maltreatment (CM) patterns with the strongest impact on the probability of heavy cannabis use (THCCOOH concentrations ≥150 ng/mL) in Iran.

PARTICIPANTS AND SETTING

Using survivor sampling, 350 adult participants were selected, and they were then allocated to three categories based on an optimal algorithm: 1) Sexual abuse, 2) Physical abuse, and 3) Physical neglect.

METHODS

From 1 September 2019 to 1 May 2023, we implemented a multicenter, matched-pairs, nested, case-control study based on the wave 3-wave 6 data of a longitudinal, multicenter, cohort study. The cases and controls (n = 350 men) were defined according to the severity of CM. The THC potency was evaluated with the delta-9 carboxy tetrahydrocannabinol (THC-COOH) levels in urine using gas chromatography/mass spectrometry (GC/MS). We calculated the population attributable fractions (PAFs) to identify the patterns of maltreatment associated with the highest odds of high-potency cannabis use.

RESULTS

Accumulating CM, including sexual abuse, physical abuse, and physical neglect, carried more than three times the risk of heavy cannabis use (OR 3.4 95 % CI 2.9-4.1), and the combination of the three indicators of maltreatment and a high BMI (25-29.9) carried more than four times the risk of heavy cannabis use (OR 4.7 95 % CI 2.7-4.1) compared to the controls. We estimated that in the case of zero CM for each of the three indicators, over 20 % of new cases of heavy cannabis use can be prevented.

CONCLUSIONS

The findings show the significance of CM as a predicator of heavy cannabis use in adulthood and in the abstinence phase.

Associations between adverse childhood experiences and history of weight cycling

Background

Adverse childhood experiences (ACEs) predict obesity onset; however, the relationship between ACEs and history of weight cycling has not been adequately explored. This gap is problematic given the difficulty in weight loss maintenance and the impact of ACEs on obesity development, chronicity, and associated weight stigma. The objective of this study was to examine associations between self-reported history of ACEs and weight cycling in a sample of weight loss treatment-seeking adults with overweight/obesity.

Methods

The number of participants in the analyzed sample was 78, mostly white educated adult women (80% female, 81% Caucasian, 75% ≥ bachelor's degree) with excess adiposity enrolled in the Cognitive and Self-regulatory Mechanisms of Obesity Study. ACEs were measured at baseline using the ACEs Scale. History of weight cycling was measured using the Weight and Lifestyle Inventory that documented weight loss(es) of 10 or more pounds.

Results

Higher ACE scores were associated with a greater likelihood of reporting a history of weight cycling. Participants with four or more ACEs had 8 times higher odds (OR = 8.301, 95% CI = 2.271-54.209, p = 0.027) of reporting weight cycling compared with participants with no ACEs. The association of weight cycling for those who endorsed one to three ACEs was not significant (OR = 2.3, 95% CI = 0.771-6.857, p = 0.135) in this sample.

Conclusions

The role of ACEs in health may be related to associations with weight cycling. Results indicated that those who reported four or more ACEs had significantly higher odds of reporting weight cycling compared with those with no ACEs. Further research is needed to further explore how ACEs predict the likelihood of weight cycling, which may be prognostic for sustained weight loss treatment response and weight stigma impacts.

The treatment of dissociative identity disorder in an eating disorder residential treatment setting

OBJECTIVE

Child maltreatment, dissociation and dissociative disorders have been noted in relationship to eating disorders (EDs) for decades, and their co-occurrence generally is associated with greater morbidity, self-harm and mortality. The concomitant presentation of dissociative identity disorder (DID) with an ED (ED + DID) is especially challenging, and there is limited information on approaches to and the effects of integrated treatment for this serious comorbidity, especially in higher levels of care. There are also limited treatment resources for such patients, since they are often turned away from specialty units due to lack of expertise with or bias toward one or the other disorder.

METHOD

We report our experience with a case series of 18 patients with DSM-5 defined ED + DID (mean age (SD) = 32.6 (11.8) years) admitted to residential treatment (RT) and assessed using validated measures for symptoms of ED, major depression (MD), PTSD, state-trait anxiety, quality of life (QOL), age of ED onset, and family involvement during treatment. All patients received integrated, multimodal, trauma-focused approaches including those based on DID practice guidelines, principles of cognitive processing therapy (CPT), and other evidence-based approaches. Fifteen of 18 patients also completed discharge reassessments, which were compared to admission values using paired t-tests.

RESULTS

Following integrated, trauma-focused RT, patients with ED + DID demonstrated statistically significant improvements in all measures, with medium (anxiety) to high (ED, PTSD, MD, QOL) effect sizes.

DISCUSSION

These results provide positive proof of concept that patients with ED + DID can be effectively treated in a specialty, trauma-focused ED program at higher levels of care.

PUBLIC SIGNIFICANCE

EDs and dissociative identity disorder (DID) are related conditions, but little is known about treating patients with both conditions. We describe the clinical features and integrated treatment of 18 such patients, 15 of whom completed discharge assessments. Significant clinical improvements were found in multiple domains (ED, PTSD, mood, anxiety, quality of life), which demonstrate positive proof of concept that ED + DID can be effectively treated in a specialty, trauma-focused ED program.

Early life adversity and obesity risk in adolescence: a 9-year population-based prospective cohort study

BACKGROUND

There are few prospective studies of factors that mediate the association between exposure to adverse childhood experiences (ACEs) and obesity in adolescence. Our aim was to address this limitation.

METHODS

We used prospective data from the Growing up in Ireland cohort study, with measurements at 9, 13, and 18 years old. The exposures were 14 adverse experiences before age 9. The main outcome was body mass index (BMI) at 18 years. Mediators were daily activity, diet quality, self-image and behavioural difficulties at 13 years.

RESULTS

Among the 4561 adolescents in the final cohort, 77.2% experienced any adversity, 50.5% were female and 26.7% were overweight/obese at 18 years. BMI Z was higher at ages 9 (0.54 vs 0.43, p < 0.05, 95% CI of difference: -0.22, -0.01) and 13 years (0.50 vs 0.35, p < 0.05, 95% CI of difference: -0.25, -0.06), in those exposed to an ACE, compared to those unexposed. Structural equation models revealed that behavioural difficulties (β = 0.01; 95% CI: 0.007-0.018, p < 0.001) and self-concept (β = 0.0027; 95% CI: 0.0004-0.0050, p = 0.026) indirectly mediate the association between exposure to ACEs and BMI at 18 years.

CONCLUSIONS

The association between ACEs and BMI in adolescence is mediated by behavioural difficulties and self-concept.

IMPACT

In a previous study, we found modest associations between exposure to a range of adverse childhood experiences and weight gain at 13 years of age. The strength of the association between adverse childhood experiences and weight gain was lower at 18 years of age compared to the association observed at 13 years and was no longer significant after controlling for confounding and including possible mediators. The association between adverse childhood experiences and BMI in adolescence is indirectly mediated by behavioural difficulties and self-concept.

Adverse Childhood Experiences and BMI: Lifecourse Associations in a Black-White U.S. Women Cohort

INTRODUCTION

Although adverse childhood experiences (ACEs) have been positively associated with adiposity, few studies have examined long-term race-specific ACE-BMI relationships.

METHODS

A Black and White all-women cohort (N=611; 48.6% Black) was followed between 1987 and 1997 from childhood (ages 9-10 years) through adolescence (ages 19-20 years) to midlife (ages 36-43 years, between 2015 and 2019). In these 2020-2022 analyses, the interaction between race and individual ACE exposures (physical abuse, sexual abuse, household substance abuse, multiple ACEs) on continuous BMI at ages 19-20 years and midlife was evaluated individually through multivariable linear regression models. Stratification by race followed as warranted at α=0.15.

RESULTS

Race only modified ACE-BMI associations for sexual abuse. Among Black women, sexual abuse was significantly associated with BMI (Badjusted=3.24, 95% CI=0.92, 5.57) at ages 19-20 years and marginally associated at midlife (Badjusted=2.37, 95% CI= -0.62, 5.35); among White women, corresponding associations were null. Overall, having ≥2 ACEs was significantly associated with adolescent BMI (Badjusted=1.47, 95% CI=0.13, 2.80) and was marginally associated at midlife (Badjusted=1.45, 95% CI= -0.31, 3.22). This was similarly observed for physical abuse (adolescent BMI: Badjusted=1.23, 95% CI= -0.08, 2.54; midlife BMI: Badjusted=1.03, 95% CI= -0.71, 2.78), but not for substance abuse.

CONCLUSIONS

Direct exposure to certain severe ACEs is associated with increased BMI among Black and White women. It is important to consider race, ACE type, and life stage to gain a more sophisticated understanding of ACE-BMI relationships. This knowledge can help strengthen intervention, prevention, and policy efforts aiming to mitigate the impacts of social adversities and trauma on persistent cardiometabolic health disparities over the lifecourse.

Assessment of Adverse Childhood Experiences and Social Determinants of Health: A Survey of Practices in Pediatric Weight Management Programs

Introduction: Adverse childhood experiences (ACEs) and social determinants of health (SDoH) are associated with increased incidence of pediatric obesity. Recent literature highlights an imperative need to assess ACEs and SDoH among youth and families with obesity to identify those individuals requiring targeted interventions. The primary objective of the present study was to examine the frequency, methodology, and barriers in evaluation of ACEs and SDoH within pediatric weight management programs (PWMPs). Methods: Invitations were e-mailed to a comprehensive directory of 92 PWMPs in the United States with a link to complete an electronic survey. Results: Forty-one PWMPs from 26 states completed the survey. Assessment of one or more ACEs and SDoH was common and typically took place during the initial patient visit by the psychologist or medical practitioner through unstructured conversations. Reported barriers to assessment included lack of time to assess and to follow-up, lack of clinic protocols, and inadequate referral resources. Programs offering bariatric surgery and those with embedded mental health clinicians reported fewer barriers to ACEs/SDoH referral resources, while family-based and healthy lifestyle-focused programs perceived more barriers related to insufficient support staff and time to follow-up with families. Conclusions: Most PWMPs assess a subset of ACEs and SDoH; however, approaches to assessment vary, are often unstructured, and several barriers remain to optimizing assessment and follow-up. Future research should evaluate standardized ACEs/SDoH assessment protocols, ideal workflow, and their impact on obesity treatment and related health outcomes.

Psychosocial and environmental risk factors of obesity and hypertension in children and adolescents-a literature overview

Childhood obesity has become a worldwide epidemic in the 21st century. Its treatment is challenging and often ineffective, among others due to complex, often not obvious causes. Awareness of the existence and meaning of psychosocial and environmental risk factors seems to be an essential element in the prevention and treatment of obesity and its complications, especially arterial hypertension. In this review, we will discuss the role of that risk factors linking obesity and increased cardiovascular disorders including the role of nutritional factors (including the role of unhealthy diet, inadequate hydration), unhealthy behaviors (e.g. smoking, alcohol and drugs, sedentary behavior, low physical activity, disrupted circadian rhythms, sleep disorders, screen exposure), unfavorable social factors (such as dysfunctional family, bullying, chronic stress, mood disorders, depression, urbanization, noise, and environmental pollution), and finally differences in cardiovascular risk in girls and boys.

Factors contributing to whether or not people with obesity undergo bariatric surgery

BACKGROUND

Bariatric surgery has been suggested as a safe and effective way to treat obesity by facilitating weight loss, but factors that predict the likelihood of bariatric surgery are unknown. The objective of this study was to describe factors associated with individuals with obesity that influence their decision to undergo bariatric surgery.

SUBJECTS AND METHODS

The study design was a cross-sectional study and participants were recruited via a survey link posted on the Obesity Action Coalition website. Demographic data, medical data, weight loss program data, and reports of personal experiences were gathered via an online survey. A multivariate logistic regression model was conducted to examine predictors associated with bariatric surgery (N = 4192).

RESULTS

Participants who took phentermine (OR=2.983), Phentermine-topiramate (Qsymia) (OR=2.863), Naltrexone-bupropion (Contrave) (OR=3.246), or Liraglutide (Saxenda) (OR=2.144) had a higher likelihood of undergoing bariatric surgery for weight loss. Participants with type 2 diabetes (OR=1.728), post-traumatic stress disorder (PTSD) (OR=1.489), or COVID-19 (OR=3.852) had a higher likelihood of undergoing bariatric surgery while sleep apnea (OR=0.760) was associated with a lower likelihood of receiving surgery. Those who used MyFitnessPal™ (OR=2.232), Noom™ (OR=1.400), Jenny Craig™ (OR=1.533), or Keto (OR=1.664) for weight loss had a higher likelihood of obtaining bariatric surgery. Personal trauma experiences of sexual abuse (OR=1.982) and physical abuse (OR=1.490) were more associated with participants who underwent surgery.

CONCLUSIONS

A variety of characteristics were associated with decisions to undergo bariatric surgery. These findings may help to determine ways to support individuals who are considering bariatric surgery.

Adverse childhood experiences, health behaviors, and associations with obesity among youth in the United States

Adverse Childhood Experiences (ACEs) affect almost half of youth in the U.S. and are linked to a host of deleterious medical and psychosocial outcomes. The current study examines the relationships among ACEs, childhood obesity, and modifiable lifestyle behaviors to inform clinical care, future research, and policy. Using data from the 2016-2018 National Survey of Children's Health (NSCH), associations between children's ACEs, weight status, and health behaviors that may influence the link between ACEs and obesity were examined. In the NSCH data, 25.3% of youth aged 10-17 years experienced one ACE with another 25.9% experiencing two or more ACEs. Having ACEs was related to excess screen time and inadequate sleep, and independently associated with obesity. Findings highlight the importance of providers screening and finding ways to intervene on behalf of youth with obesity. The present provides guidelines for providers on intervening with youth experiencing ACEs.

Association of early life physical and sexual abuse with premature mortality among female nurses: prospective cohort study

OBJECTIVE

To explore associations between early life physical and sexual abuse and subsequent risk of premature mortality (death before age 70 years).

DESIGN

Prospective cohort study.

SETTING

The Nurses' Health Study II (2001-19).

PARTICIPANTS

67 726 female nurses aged 37-54 years when completing a violence victimization questionnaire in 2001.

MAIN OUTCOME MEASURES

Hazard ratios and 95% confidence intervals for total and cause specific premature mortality by childhood or adolescent physical and sexual abuse, estimated by multivariable Cox proportional hazard models.

RESULTS

2410 premature deaths were identified over 18 years of follow-up. Nurses who experienced severe physical abuse or forced sexual activity in childhood and adolescence had a higher crude premature mortality rate than nurses without such abuse in childhood or adolescence (3.15 v 1.83 and 4.00 v 1.90 per 1000 person years, respectively). The corresponding age adjusted hazard ratios for premature deaths were 1.65 (95% confidence interval 1.45 to 1.87) and 2.04 (1.71 to 2.44), respectively, which were materially unchanged after further adjusting for personal characteristics and early life socioeconomic status (1.53, 1.35 to 1.74, and 1.80, 1.50 to 2.15, respectively). Cause specific analyses indicated that severe physical abuse was associated with a greater risk of mortality due to external causes of injury and poisoning (multivariable adjusted hazard ratio 2.81, 95% confidence interval 1.62 to 4.89), suicide (3.05, 1.41 to 6.60), and diseases of the digestive system (2.40, 1.01 to 5.68). Forced sexual activity as a child and adolescent was associated with greater risk of mortality due to cardiovascular disease (2.48, 1.37 to 4.46), external injury or poisoning (3.25, 1.53 to 6.91), suicide (4.30, 1.74 to 10.61), respiratory disease (3.74, 1.40 to 9.99), and diseases of the digestive system (4.83, 1.77 to 13.21). The association of sexual abuse with premature mortality was stronger among women who smoked or had higher levels of anxiety during adulthood. Smoking, low physical activity, anxiety, and depression each explained 3.9-22.4% of the association between early life abuse and premature mortality.

CONCLUSION

Early life physical and sexual abuse could be associated with a greater risk of adult premature mortality.

Relationship Between Childhood Abuse and Body Mass Index in Young Adulthood: Mediated by Depression and Anxiety?

We examined whether childhood abuse is related to body mass index (BMI) in young adults and whether this relationship is mediated by depression and anxiety. Data are from the Dutch longitudinal cohort study TRAILS (n_females = 836, n_males = 719). At wave 4, childhood sexual, physical and verbal abuse, and lifetime major depressive disorder (MDD) and generalized anxiety disorder (GAD) were assessed. BMI was measured at wave 4 and 5 (mean age = 19.2/22.4 years). Sex-stratified structural equation models were estimated. Females who had experienced sexual abuse had a higher BMI at wave 4 (B = 0.97, 95%CI = [-0.01,1.96]) and a higher increase in BMI between wave 4 and 5 (B = 0.52, 95%CI = [0.04,1.01]) than females who had not experienced sexual abuse. Additionally, MDD and BMI at wave 4 were related in females (B = 1.35, 95%CI = [0.52,2.18]). MDD mediated the relationship between sexual abuse and BMI at wave 4 in females. In addition, sexual abuse moderated the relationship between MDD and BMI at wave 4. The relationship was stronger among females who had experienced sexual abuse than among females who had not. Prevention of BMI changes among females who experienced sexual abuse may thus be warranted, particularly when they developed MDD. MDD treatment, such as abuse-focused psychotherapy, may aid this prevention.

Childhood maltreatment predicts physical health in college students

Objective: Childhood maltreatment (CM) is associated with physical health problems throughout the lifespan, yet more research is needed regarding the trajectory of health problems (e.g., onset of health risk indicators) in young adults. The current study examined whether college students self-reporting higher levels of CM exhibited poorer physical health outcomes. Method: Young adults in college (N = 100) completed a physical health assessment (heart rate, body mass index (BMI), blood pressure, blood sugar, waist circumference), self-reported measures of health (symptoms of illness), and CM during spring semester 2018. Results: CM scores predicted higher heart rate and increased symptoms of illness. Females with maltreatment history presented higher levels of obesity and more metabolic syndrome conditions than their peers. Conclusions: Findings support the importance of examining the trajectory of CM to chronic disease, as health risk indicators are present in young adults.

Depression, cardiometabolic disease, and their co-occurrence after childhood maltreatment: an individual participant data meta-analysis including over 200,000 participants

BACKGROUND

Childhood maltreatment is associated with depression and cardiometabolic disease in adulthood. However, the relationships with these two diseases have so far only been evaluated in different samples and with different methodology. Thus, it remains unknown how the effect sizes magnitudes for depression and cardiometabolic disease compare with each other and whether childhood maltreatment is especially associated with the co-occurrence ("comorbidity") of depression and cardiometabolic disease. This pooled analysis examined the association of childhood maltreatment with depression, cardiometabolic disease, and their comorbidity in adulthood.

METHODS

We carried out an individual participant data meta-analysis on 13 international observational studies (N = 217,929). Childhood maltreatment comprised self-reports of physical, emotional, and/or sexual abuse before 18 years. Presence of depression was established with clinical interviews or validated symptom scales and presence of cardiometabolic disease with self-reported diagnoses. In included studies, binomial and multinomial logistic regressions estimated sociodemographic-adjusted associations of childhood maltreatment with depression, cardiometabolic disease, and their comorbidity. We then additionally adjusted these associations for lifestyle factors (smoking status, alcohol consumption, and physical activity). Finally, random-effects models were used to pool these estimates across studies and examined differences in associations across sex and maltreatment types.

RESULTS

Childhood maltreatment was associated with progressively higher odds of cardiometabolic disease without depression (OR [95% CI] = 1.27 [1.18; 1.37]), depression without cardiometabolic disease (OR [95% CI] = 2.68 [2.39; 3.00]), and comorbidity between both conditions (OR [95% CI] = 3.04 [2.51; 3.68]) in adulthood. Post hoc analyses showed that the association with comorbidity was stronger than with either disease alone, and the association with depression was stronger than with cardiometabolic disease. Associations remained significant after additionally adjusting for lifestyle factors, and were present in both males and females, and for all maltreatment types.

CONCLUSIONS

This meta-analysis revealed that adults with a history of childhood maltreatment suffer more often from depression and cardiometabolic disease than their non-exposed peers. These adults are also three times more likely to have comorbid depression and cardiometabolic disease. Childhood maltreatment may therefore be a clinically relevant indicator connecting poor mental and somatic health. Future research should investigate the potential benefits of early intervention in individuals with a history of maltreatment on their distal mental and somatic health (PROSPERO CRD42021239288).

Parental absence during childhood and weight status in adulthood among middle-aged community dwellers in rural Vietnam

OBJECTIVES

While adverse childhood experiences (ACEs) have been shown to be associated with adulthood obesity, less is known about their association with underweight. We examined the associations between parental absence (i.e., a major component of ACEs) and both underweight and excess weight among middle-aged rural community dwellers in Vietnam, where experiences of parental absence was not uncommon during and after the Vietnam War (1955-1975).

METHODS

Data came from 3000 middle-aged adults who participated in the baseline survey of Khánh Hòa Cardiovascular Study. Parental absence was defined as parental absence due to death, divorce, or out-migration. Using information on the timing of such events, we categorized participants into those who experienced parental absence before the age of 3, between the ages of 3 and 15, and those without such experiences. BMI was calculated based on measured height and weight (kg/m² ) and categorized into three groups: underweight <18.5; normal 18.5-24.9; excess weight ≥ 25. Multinomial logistic regression was then used to investigate the association between parental absence and adult weight status.

RESULTS

Parental absence that occurred before the age of 3 was marginally significantly associated with underweight (relative risk ratio [RRR] = 1.44, 95% confidence interval [CI] 0.95, 2.20) but not with overweight/obesity. Parental divorce was associated with overweight/obesity (RRR = 2.48, 95% CI 1.28, 4.81), but not parental absence due to migratory work.

CONCLUSIONS

While previous studies in Western settings focused almost exclusively on the risk of obesity in relation to exposure to ACEs, our findings point to the potential importance of considering the risk of underweight in low- and middle-income countries.

Lifetime stressor exposure, eating expectancy, and acute social stress-related eating behavior: A pre-registered study of the emotional eating cycle

Eating behaviors in response to acute stressors are highly variable: whereas many individuals eat more following stressors, others eat less or show no change in food consumption. Understanding factors that predict individual differences in eating behaviors may help elucidate the psychosocial mechanisms underlying obesity, yet few experimental studies on this topic have been conducted to date. To address this issue, we conducted the present pre-registered study, where we investigated how lifetime stressor exposure moderates the extent to which eating expectancies enhance the learned association between stress-induced negative affect and snack intake. Participants were 44 women (30% non-White) between 18 and 50 years old (M = 27.9), with a mean body mass index of 25.6, who completed assessments of lifetime stressor exposure, eating behaviors, and eating expectancies (eating helps manage negative affect); in a subsequent visit, they were given snacks after an acute social stress task (TSST). The moderated moderation model (PROCESS model 3) yielded a significant three-way interaction. When eating expectancies were high, acute social stress-induced negative affect predicted greater M&M intake for women with very high total lifetime stressor exposure but less M&M intake for women with fewer lifetime stressors. These data thus highlight how lifetime stressor exposure interacts with eating expectancies and acute stress-induced negative affect to predict eating behavior. Replications in larger samples may help explain variability in stress-eating as well as how lifetime stressors contribute to obesity.

Effect of childhood maltreatment on cognitive function and its relationship with personality development and social coping style in major depression disorder patients: A latent class model and network analysis

Study objectives

The study aimed to (1) analyze the interrelationships among different types of childhood adversity, diverse personality dimensions, and individual coping style integratively among major depressive disorder (MDD) patients and healthy participants using a network approach; (2) explore the latent class of child maltreatment (CM) and its relationship with cognitive function.

Methods

Data were collected from the Objective Diagnostic Markers and Personalized Intervention in MDD Patients (ODMPIM) study, including 1,629 Chinese participants. Using the Childhood Trauma Questionnaire to assess CM, the Simplified Coping Style Questionnaire to measure individual coping style, Eysenck Personality Questionnaire Revised-Short Form for personality characters, and a series of neurocognitive tests, including seven tests with 18 subtests for cognitive assessments. We used the "Network Module" in Jeffreys's Amazing Statistics Program (JASP) and R package for network analysis. A latent class analysis was performed with SAS9.4.

Results

Child maltreatment was more common in MDD patients than in healthy controls, except for emotional abuse. Network analysis showed that emotional abuse, emotional neglect, physical abuse, and physical neglect formed quadrangle connections. Personality dimensions were associated with physical neglect and emotional abuse. All types of CM (excluding sex abuse) showed an association with coping style. Emotional neglect showed the highest centrality measures. Physical neglect had a high level of closeness. To a concerning strength, emotional and physical neglect showed the highest levels. The structure of the networks is variant between groups (M = 0.28, P = 0.04). Latent class analysis (LCA) revealed that three classes provided the best fit statistics. Neglect and abuse classes tended to perform more poorly on the five cognitive domains.

Conclusion

This study provided insights on multi-type of CM. Neglect played an important role in different routes through the relation between CM with personality traits and social coping style. However, neglect has often been ignored in previous studies and should receive more public attention.

The social origins of obesity within and across generations

We propose a model for obesity development that traces a considerable part of its origins to the social domain (mainly different forms of prolonged social adversity), both within and across generations, working in tandem with a genetic predisposition. To facilitate overview of social pathways, we place particular focus on three areas that form a cascading sequence: (A) social adversity within the family (parents having a low education, a low social position, poverty and financial insecurity; offspring being exposed to gestational stress, unmet social and emotional needs, abuse, maltreatment and other negative life events, social deprivation and relationship discord); (B) increasing levels of insecurity, negative emotions, chronic stress, and a disruption of energy homeostasis; and (C) weight gain and obesity, eliciting further social stress and weight stigma in both generations. Social adversity, when combined with genetic predisposition, thereby substantially contributes to highly effective transmission of obesity from parents to offspring, as well as to obesity development within current generations. Prevention efforts may benefit from mitigating multiple types of social adversity in individuals, families, and communities, notably poverty and financial strain, and by improving education levels.

Adverse childhood experiences increase the risk for eating disorders among adolescents

Purpose

Traumatic events often feature prominently in eating disorders. A questionnaire survey to assess the relation of eating disorder risk to the frequency of adverse childhood experiences (ACEs) and the possible association of eating disorder risk with a particular type of ACE was conducted in a community sample of Hungarian adolescents.

Methods

Demographic and anthropometric data, risk for eating disorders (by SCOFF questionnaire), and ACEs (by ACE score calculator) were collected from 432 adolescents aged 12-17 years.

Results

Adolescents who had undergone four or more ACEs were 5.7 times more likely to be in the high eating disorder risk group than those who did not report any ACEs. Cumulative maltreatment showed a greater association with overall risk for eating disorders than cumulative family dysfunction. There is an increased risk of eating disorders from emotional maltreatment (OR = 3.475), physical maltreatment (OR = 3.440), sexual maltreatment (OR = 10.973), and emotional neglect (OR = 3.331). Dysfunctional family circumstances revealed an association with household mental illness (OR = 3.401).

Conclusion

Our study of the connection between eating disorder risk and ACE is the first of its kind in Central and Eastern Europe. Maltreatments had a greater role than family dysfunctions in increasing the risk of eating disorders. Our findings contribute to a more precise understanding of the role that ACEs play in eating disorders. It is important to bring to clinicians' attention the importance of ACEs in the diagnosis and therapy of eating disorders and their potentially fundamental significance for therapy.

The association between childhood trauma and overweight and obesity in young adults: the mediating role of food addiction

PURPOSE

Childhood trauma is associated with increased risk of obesity during adulthood, which may be associated with the development of food addiction. This study examined whether food addiction mediated the relationship between childhood trauma and obesity in young adults.

METHODS

A sample of 512 young adults, aged 18 to 30 years, living with overweight and obesity (Body Mass Index ≥ 25 kg/m2), from the United Kingdom participated in the study. Participants completed the Childhood Trauma Questionnaire (CTQ), the Yale Food Addiction Scale, and provided their current height and weight to compute their Body Mass Index (BMI).

RESULTS

Using the PROCESS macro, a mediation analysis found that food addiction accounted for 45% of variance in the relationship between childhood trauma and BMI. Post hoc analyses were conducted to examine the mediating effect of food addiction across each of the five subscales of the CTQ (emotional/physical/sexual abuse and emotional/physical neglect). Food addiction accounted for 32% to 51% of the variance in the relationship between each CTQ subscale and BMI.

CONCLUSIONS

These findings suggest that experiences of childhood trauma are associated with the development of overweight and obesity during early adulthood and up to half of this relationship can be attributed to food addiction, which is likely used as a maladaptive coping mechanism in response to trauma. Young adults living with overweight and obesity who report experiences of childhood trauma may benefit from the support of clinical and counselling psychologists to improve their understanding of the underlying psychosocial factors that influence their eating behaviours.

Child and Adolescent Abuse Patterns and Incident Obesity Risk in Young Adulthood

INTRODUCTION

Child abuse is associated with adult obesity. Yet, it is unknown how the developmental timing and combination of abuse types affect this risk. This report examined how distinct child and adolescent abuse patterns were associated with incident obesity in young adulthood.

METHODS

Data came from 7,273 participants in the Growing Up Today Study, a prospective cohort study in the U.S. with 14 waves from 1996 to 2016 (data were analyzed during 2020-2021). An abuse group variable was empirically derived using latent class analysis with indicators for child (before age 11 years) and adolescent (ages 11-17 years) physical, sexual, and emotional abuse. Risk ratios for obesity developing during ages 18-30 years were estimated using modified Poisson models. Associations of abuse groups with BMI across ages 18-30 years were then examined using mixed-effects models. All models were stratified by sex.

RESULTS

Among women, groups characterized by abuse had higher BMIs entering young adulthood and greater changes in BMI per year across young adulthood. Groups characterized by multiple abuse types and abuse sustained across childhood and adolescence had approximately twice the risk of obesity as that of women in a no/low abuse group. Associations were substantially weaker among men, and only a group characterized by physical and emotional abuse in childhood and adolescence had an elevated obesity risk (risk ratio=1.38; 95% CI=1.04, 1.83).

CONCLUSIONS

Obesity risk in young adulthood varied by distinct abuse groups for women and less strongly for men. Women who experience complex abuse patterns have the greatest risk of developing obesity in young adulthood.

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.

Childhood adversity and cardiometabolic biomarkers in mid-adulthood in the 1958 British birth cohort

Studies that have examined associations between adverse childhood experiences (ACEs) and cardiometabolic biomarkers in adulthood are limited as they mainly focus on childhood maltreatment. This study aimed to examine the association between a range of prospectively and retrospectively reported ACEs and cardiometabolic biomarkers in mid-adulthood. Multiply-imputed data on 8511 participants from the National Child Development Study (1958 British birth cohort) were used. ACEs were prospectively reported at ages 7, 11 and 16, and retrospectively reported at age 33/44/45. Cardiometabolic outcomes assessed at age 44/45 included glycated haemoglobin (HbA1c), cholesterol (total, low-density lipoprotein (LDL) and high-density lipoprotein (HDL)), triglycerides, blood pressure (systolic and diastolic), body mass index, waist circumference and metabolic syndrome. Parental separation/divorce, physical neglect, emotional neglect and psychological abuse were associated with lower HDL cholesterol. Parental offending and physical neglect were associated with higher triglyceride concentrations. Parental offending was also associated with increased HbA1c. Exposure to 2+ (vs. 0) prospective ACEs was associated with lower HDL cholesterol. All these associations were after adjustment for sex and multiple early life factors. To conclude, several individual ACEs are associated with poorer cardiometabolic risk factor profiles in mid-adulthood. Furthermore, exposure to two or more prospective ACEs is associated with lower HDL cholesterol concentrations in mid-adulthood.

•

Parental separation/divorce in childhood is associated with lower high-density lipoprotein cholesterol in mid-adulthood.

•

Physical neglect in childhood is associated with poorer lipid profiles in mid-adulthood.

•

Psychological abuse in childhood is associated with lower high-density lipoprotein cholesterol in mid-adulthood.

•

Parental offending in childhood is associated with higher triglycerides and glycated haemoglobin in mid-adulthood.

Obesity in Adolescents: Understanding the Combined Role of Food Security and Emotional and Behavioral Disorders

PURPOSE

To examine the associations and interactions between levels of food security and emotional and behavioral disorders with obesity in adolescents.

METHODS

Multiple logistic regression modeling was used to analyze the association of adolescent obesity with levels of food security and emotional and behavior disorders in children aged 12-17 years using data from National Health Interview Survey 2016-2018 combined years. Presence of emotional and behavioral disorders within food security categories was added to logistic regression modeling to examine interactions.

RESULTS

When added individually to multiple logistic regression models, marginal and low food security, Attention Deficit Hyperactivity Disorder (ADHD) and anxiety were associated with increased odds of obesity, but very low food security and depression were not. Within the group of adolescents with very low food security, those with anxiety, depression, or ADHD had a nearly two to three-fold increase in odds of obesity compared to adolescents with very low food security and no emotional and behavioral disorders. A similar increase in the odds of obesity with the presence of anxiety, depression, or ADHD was not seen in the adolescents with high food security.

DISCUSSION

This study finds a significant interaction between food security level and emotional and behavioral disorders. The distinction that very low food security in adolescents is only associated with obesity when either anxiety, depression or ADHD are present, but not independently, is an important contribution to understanding complex interactions contributing to obesity.

BMI moderates the association between adverse childhood experiences and COPD

OBJECTIVES

Cigarette smoking and obesity are leading risk factors for chronic obstructive pulmonary disease (COPD). Although studies have established an association between adverse childhood experiences (ACEs) and COPD, few studies have examined whether this association is moderated by cigarette smoking or body mass index (BMI). This cross-sectional study examined the association between ACEs and COPD, and whether cigarette smoking or BMI moderates this association.

METHODS

Data for this study came from the 2019 Behavioral Risk Factor Surveillance System survey. An analytic sample of 75,700 adults aged 18-79 years (50.7% female) were analyzed using binary logistic regression. The outcome variable investigated was self-reported physician-diagnosed COPD, and the main explanatory variable was ACEs.

RESULTS

Of the 75,700 respondents examined, 8.1% had COPD. About one in three (33.6%) respondents had no ACEs, 23.1% had one ACE, and about one in five (20.2%) had four or more ACEs. In the multivariable binary logistic regression, we found that the association between ACEs and COPD differs by BMI status. Controlling for the effects of other factors, the association between ACEs and COPD is strongest for respondents who are obese (AOR = 1.41, 95% CI = 1.04-1.91).

CONCLUSIONS

The findings of this study demonstrate that ACEs are associated with COPD later in adulthood, and BMI moderated this association. The findings of this study add to the number of studies demonstrating the adverse impact of ACEs on chronic health outcomes among adults.

Clinic screening for adverse childhood experiences in people living with HIV to Improve Care Delivery

Adverse childhood experiences (ACEs) are associated with negative health outcomes; however, screening for ACEs is not routinely performed among people living with HIV (PLWH). We conducted a single-center, cross-sectional pilot study to define the (1) prevalence of ACEs in PLWH and (2) acceptability of ACEs screening in routine out-patient clinical care. One hundred participants completed screening: median age of participants was 49 years (interquartile range: 38.5-59.5), 73% male, 66% Non-Hispanic Black/African American, and 47% gay/lesbian. Clinically significant ACEs score, defined as ≥4, was reported in 51%. High ACEs score was more common among participants <50 years old (64.7% vs. 36.7%; p < 0.01), but the prevalence of ACEs ≥4 did not differ by gender, race, ethnicity, or sexual orientation. Among participants with ≥4 ACEs, 44.4% screened negative on both PHQ-9 and PC-PTSD screens. The majority of participants (89%) reported a positive experience with ACEs screening. The prevalence of clinically significant ACEs in this clinic population of PLWH was more than twice that reported in the general population. Routine ACEs screening can improve delivery of trauma-informed care in the HIV primary care setting.

Knowledge, experiences and attitudes of midwives in maternity care in encounters with pregnant women with obesity - are adverse childhood experiences understood and explored as a contributing factor?

OBJECTIVE

To explore knowledge, experiences and attitudes of midwives in maternity care in encounters with pregnant women with obesity, and whether they investigate adverse childhood experiences as a contributing factor to the weight challenges.

DESIGN

Semi-structured interviews were undertaken to explore midwives' experiences of providing maternity care for women with obesity. For data analysis, Malterud's systematic text condensation was used, a method for thematic cross-case analysis of qualitative data with an inductive approach.

PARTICIPANTS AND SETTING

Nine midwives working in maternity care in Central Norway. The interviews were conducted online or at the midwives' workplace.

FINDINGS

The midwives routinely investigated pregnant women's childhood, but few saw a link between adverse childhood experiences and obesity. Pregnant women with obesity were perceived by the midwives as particularly vulnerable, which led to a sensitive, individualised approach focusing on trust and relationship building. This approach, in addition to pointing out complications that can occur with obesity, was described as a balancing act. The midwives described preventative healthcare as a natural task, but hectic days with many competing tasks were seen as an obstacle. The women's motivation for lifestyle change was experienced differently by the midwives; some described strong motivation while others mentioned poor motivation. The midwives found it reassuring to have experience to draw on in broaching difficult topics.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Midwives' many years of experience enable them to approach obese pregnant women in an individual and careful way. Their mission in public health could be better utilised if they explored negative childhood experiences in relation to pregnant women's weight challenges.

The weight of childhood adversity: evidence that childhood adversity moderates the impact of genetic risk on waist circumference in adulthood

OBJECTIVE

The present study tested the interactive effects of childhood adversity and polygenic risk scores for waist circumference (PRS-WC) on waist circumference (WC). Consistent with a diathesis-stress model, we hypothesize that the relationship between PRS-WC and WC will be magnified by increasing levels of childhood adversity.

METHODS

Observational study of 7976 adults (6347 European Americans and 1629 African Americans) in the Health and Retirement Study with genotyped data. PRS-WC were calculated by the HRS administrative core using the weighted sum of risk alleles based on a genome-wide association study conducted by the Genetic Investigation of Anthropometric Traits (GIANT) consortium. Childhood adversity was operationalized using a sum score of three traumatic events that occurred before the age of 18 years.

RESULTS

There was a statistically significant interaction between PRS-WC and childhood adversity for European Americans, whereby the magnitude of PRS-WC predicting WC increased as the number of adverse events increased.

CONCLUSIONS

This study supports the idea of the interactive effects of genetic risks and childhood adversity on obesity. More epidemiological studies, particularly with understudied populations, are needed to better understand the roles that genetics and childhood adversity play on the development and progression of obesity.

The association between childhood sexual abuse and historical intimate partner violence with body mass index and diabetes: Evidence from the Australian Longitudinal Study on Women's Health

The purpose of this study was to investigate the associations of childhood sexual abuse and historical intimate partner violence with body mass index and diabetes among mid-age women. Data from 5782 participants in the 1946-51 cohort of the Australian Longitudinal Study on Women's Health were used. The association of abuse reported to have occurred before 1996 with body mass index and incident diabetes during 20 years of follow-up were examined using longitudinal logistic regression. Women who experienced childhood sexual abuse only, historical intimate partner violence only, or both forms of abuse had higher risk of obesity compared to women who did not experience either form of abuse. The associations between experiencing childhood sexual abuse only, historical intimate partner violence only, or both forms of abuse and incident diabetes (adjusted odds ratios, AOR = 1.28, 95%CI = 1.00, 1.65, AOR = 1.27 (1.02, 1.58) and AOR = 1.74 (1.27, 2.38) respectively) were attenuated by adding body mass index and other variables in the model (AOR = 1.16, 95%CI = 0.90, AOR = 1.49, 1.17 (0.94, 1.46) and AOR = 1.41 (1.03, 1.95) respectively) compared with women who did not experience abuse. The clinical implication is that awareness of a woman's early life experience of abuse may provide insight into managing her weight and risk of diabetes.

Maladaptive Eating Behaviors and Childhood Trauma: A Focus on Food Addiction

Background

Many studies have highlighted the clinical relevance of food addiction (FA) by showing its association with psychopathological severity and even more when co-occurring with binge eating disorder. It was suggested that the association between FA and greater psychopathological severity could be accounted for by a history of traumatic experiences. The present study examined the relationship between childhood trauma (including peer victimization, abuse, and neglect) and maladaptive eating behaviors (FA, binge eating, and grazing) and explored whether childhood trauma predicts FA when controlling for binge eating, grazing, and other confounding variables.

Methods

One hundred fourteen adult women seeking psychological help for problems related to eating or weight completed questionnaires measuring FA, binge eating, grazing, depressive symptoms, peer victimization, and childhood abuse and neglect.

Results

FA showed significantly small to moderate positive correlations with all measures of childhood trauma, except for physical neglect. A hierarchical regression, including binge eating, grazing, depressive symptoms, age, and childhood trauma explained 55% of FA variance, with 7% of variance explained uniquely by childhood trauma.

Conclusions

This study supports that FA is related to childhood trauma and provides a potential explanation for the association of FA with greater psychopathological severity. From a clinical perspective, FA provides an accurate and quick assessment of psychopathological severity and represents an essential complement to the evaluation of eating disorders related to overweight. Future studies should attempt to estimate the impact of childhood trauma on treatment outcomes.

Adverse childhood experiences, child poverty, and adiposity trajectories from childhood to adolescence: evidence from the Millennium Cohort Study

Objective

This study investigated associations between adverse childhood experiences (ACEs) in early childhood (at ages 9 months and 3 years) and adiposity trajectories of children/adolescents from age 5 to age 17, and the potential interaction between ACEs and poverty on adiposity trajectories.

Methods

Data from the UK Millennium Cohort Study was used. Eight commonly studied ACEs and poverty were measured when the child was aged 9 months and 3 years. ACEs were considered as a cumulative score and as individual experiences. Linear-mixed effect models were employed, modelling BMI and fat mass index (FMI) trajectories from age 5 to 17 (main outcome), adjusting for covariates and stratified by sex. Interactions with poverty were also tested. The sample sizes were 7282 and 6912 for BMI and FMI sample respectively.

Results

Cumulative ACE score was associated with steeper increase in BMI and FMI among boys with 3+ ACEs (BMI: β = 0.13, 95% CI: 0.02–0.24; FMI: β = 0.09, 95% CI: 0.01–0.19). For individual ACEs, parental depression was associated with steeper increase in BMI/FMI trajectories in both sexes (BMI: boys: β = 0.15, 95% CI: 0.07–0.23, girls: β = 0.13, 95% CI: 0.05–0.20; FMI: boys: β = 0.09, 95% CI: 0.03–0.15, girls: β = 0.09, 95% CI: 0.02–0.16). In addition, parental separation and physical punishment were associated with steeper increase in BMI/FMI trajectories among girls (BMI: parental separation: β = 0.25; 95% CI: 0.06–0.44, physical punishment: β = 0.14; 95% CI: 0.03–0.26; FMI: parental separation: β = 0.20; 95% CI: 0.03–0.37, physical punishment: β = 0.12; 95% CI: 0.02–0.22). No interaction effect had been found between ACEs and poverty on the adiposity trajectories.

Conclusions

A complex relationship between ACEs in early childhood and adiposity trajectories for children/adolescents was found, highlighting the different effects of specific ACEs and sex differences in the association.

Child maltreatment and hypothalamic-pituitary-adrenal axis functioning: A systematic review and meta-analysis

Alterations in hypothalamic-pituitary-adrenal (HPA) axis and its effector hormone cortisol have been proposed as one possible mechanism linking child maltreatment experiences to health disparities. In this series of meta-analyses, we aimed to quantify the existing evidence on the effect of child maltreatment on various measures of HPA axis activity. The systematic literature search yielded 1,858 records, of which 87 studies (k = 132) were included. Using random-effects models, we found evidence for blunted cortisol stress reactivity in individuals exposed to child maltreatment. In contrast, no overall differences were found in any of the other HPA axis activity measures (including measures of daily activity, cortisol assessed in the context of pharmacological challenges and cumulative measures of cortisol secretion). The impact of several moderators (e.g., sex, psychopathology, study quality), the role of methodological shortcomings of existing studies, as well as potential directions for future research are discussed.

The Intersection of Neighborhood Environment and Adverse Childhood Experiences: Methods for Creation of a Neighborhood ACEs Index

This study evaluated methods for creating a neighborhood adverse childhood experiences (ACEs) index, a composite measure that captures the association between neighborhood environment characteristics (e.g., crime, healthcare access) and individual-level ACEs exposure, for a particular population. A neighborhood ACEs index can help understand and address neighborhood-level influences on health among individuals affected by ACEs. Methods entailed cross-sectional secondary analysis connecting individual-level ACEs data from the Philadelphia ACE Survey (n = 1677) with 25 spatial datasets capturing neighborhood characteristics. Four methods were tested for index creation (three methods of principal components analysis, Bayesian index regression). Resulting indexes were compared using Akaike Information Criteria for accuracy in explaining ACEs exposure. Exploratory linear regression analyses were conducted to examine associations between ACEs, the neighborhood ACEs index, and a health outcome—in this case body mass index (BMI). Results demonstrated that Bayesian index regression was the best method for index creation. The neighborhood ACEs index was associated with higher BMI, both independently and after controlling for ACEs exposure. The neighborhood ACEs index attenuated the association between BMI and ACEs. Future research can employ a neighborhood ACEs index to inform upstream, place-based interventions and policies to promote health among individuals affected by ACEs.

Do adverse childhood experiences and genetic obesity risk interact in relation to body mass index in young adulthood? Findings from the National Longitudinal Study of Adolescent to Adult Health

BACKGROUND

Few studies have focused on the role of adverse childhood experiences (ACEs) in relation to genetic susceptibility to obesity.

OBJECTIVE

We aimed to examine the interaction between the presence of ACEs (i.e., physical, psychological and sexual abuse) before the age of 18 and BMI polygenic score.

METHODS

Data came from the National Longitudinal Study of Adolescent to Adult Health (Add Health) Wave IV (2007/2008) where saliva samples were collected for DNA genotyping and information on BMI and ACEs were obtained from 5854 European American (EA), 2073 African American (AA) and 1448 Hispanic American (HA) participants aged 24 to 32 years old. Polygenic scores were calculated as the sum of the number of risk alleles of BMI-related SNPs which were weighted by effect size. A race/ethnicity-stratified mixed-effects linear regression model was used to test for differential association between BMI polygenic score and BMI by the presence of ACEs.

RESULTS

We did not find any evidence of significant interaction between ACEs and polygenic score in relation to BMI among EA (p = 0.289), AA (p = 0.618) or HA (p = 0.870). In main effects models, polygenic score was positively associated with BMI in all race/ethnic groups, yet the presence of ACEs was associated with increased BMI only among EA.

CONCLUSION

We did not find any evidence that ACEs exacerbate genetic predisposition to increased BMI in early adulthood.

How does childhood maltreatment influence cardiovascular disease? A sequential causal mediation analysis

BACKGROUND

Childhood maltreatment has been consistently associated with cardiovascular disease (CVD). However, the mechanisms of this relationship are not yet fully understood. We explored the relative contribution of anxiety/depression, smoking, body mass index (BMI) and inflammation (C-reactive protein, CRP) to the association between childhood maltreatment and CVD in men and women aged 40-69 years in the UK.

METHODS

We used data from 40 596 men and 59 511 women from UK Biobank. To estimate the indirect effects of childhood maltreatment (physical, sexual and emotional abuse, and emotional and physical neglect) on incident CVD via each of the mediators, we applied a sequential mediation approach.

RESULTS

All forms of maltreatment were associated with increased CVD risk [hazard ratios (HRs) ranging from 1.09 to 1.27]. Together, anxiety/depression, smoking, BMI and inflammation (indexed by CRP) mediated 26-90% of the association between childhood maltreatment and CVD, and the contribution of these mediators differed by type of maltreatment and sex. Anxiety/depression mediated the largest proportion of the association of sexual abuse, emotional abuse and emotional neglect with CVD (accounting for 16-43% of the total effect), especially in women. In men, BMI contributed the most to the indirect effect of associations of physical abuse and physical neglect with CVD; in women, anxiety/depression and BMI had similar contributions.

CONCLUSIONS

These findings add to the understanding of how childhood maltreatment affects CVD risk and identify modifiable mediating factors that could potentially reduce the burden of CVD in people exposed to maltreatment in early life.

Limitations of the protective measure theory in explaining the role of childhood sexual abuse in eating disorders, addictions, and obesity: an updated model with emphasis on biological embedding

In addition to its immediate negative consequences, childhood sexual abuse is associated with lifelong deleterious mental and physical health outcomes. This review employs a biopsychosocial perspective to better understand pathways from childhood sexual abuse to eating disorders, food and drug addictions, and obesity across the life course. Guided by an updated conceptual model, this review delineates how the biological embedding of childhood sexual abuse triggers a cascade of interrelated conditions that often result in failed attempts at weight suppression and eventually obesity. Such biological embedding involves pathways such as inflammation, allostatic load, reward sensitivity, activation of the hypothalamic-pituitary-adrenal axis, epigenetics, and structural and functional changes in the brain. These pathways are in turn theorized to lead to food addiction, substance use disorder, and eating disorders-each with potential pathways toward obesity over time. Predisposing factors to childhood sexual abuse including gender, culture, and age are discussed. This model calls into question the longstanding "protective measure" theory that purports individuals exposed to sexual abuse will deliberately or subconsciously gain weight in attempt to prevent future victimization. A more comprehensive understanding of the mechanisms by which childhood sexual abuse becomes biologically embedded may help clinicians and survivors normalize and/or address disordered eating and weight-related outcomes, as well as identify intervention strategies.Level of evidence: Level V: opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

The impact of a history of child abuse on cognitive performance: a cross-sectional study in older patients with a depressive, anxiety, or somatic symptom disorder

BACKGROUND

Child abuse is a major global burden with an enduring negative impact on mental and physical health. A history of child abuse is consistently associated with worse cognitive performance among adults; data in older age groups are inconclusive. Since affective symptoms and cognitive functioning are interrelated among older persons, a synergistic effect can be assumed in patients with affective symptoms who also have suffered from child abuse. This study examines the association between a history of child abuse and cognitive performance in such patients.

METHODS

Cross-sectional data were collected from the 'Routine Outcome Monitoring for Geriatric Psychiatry & Science' project, including 179 older adults (age 60-88 years) with either a unipolar depressive, any anxiety, or somatic symptom disorder referred to specialized geriatric mental health care. A history of physical, sexual, and psychological abuse, and emotional neglect was assessed with a structured interview. Cognitive functioning was measured with three paper and pencils tests (10-words verbal memory test, Stroop Colour-Word test, Digit Span) and four tests from the computerized Cogstate Test Battery (Detection Test, Identification Test, One Card Learning Test, One Back Test). The association between a history of child abuse and cognitive performance was examined by multiple linear regression analyses adjusted for covariates.

RESULTS

Principal component analyses of nine cognitive parameters revealed four cognitive domains, i.e., visual-verbal memory, psychomotor speed, working memory and interference control. A history of child abuse was not associated with any of these cognitive domains. However, when looking at the specific types of child abuse separately, a history of physical abuse and emotional neglect were associated with poorer interference control. A history of physical abuse was additionally associated with better visual-verbal memory.

CONCLUSIONS

The association between a history of child abuse and cognitive performance differs between the different types of abuse. A history of physical abuse might particularly be a key determinant of cognitive performance in older adults with a depressive, anxiety, or somatic symptom disorder. Future studies on the impact of these disorders on the onset of dementia should take child abuse into account.

History of abuse and bariatric surgery outcomes: a systematic review

BACKGROUND

Although there is evidence to support the relationship between abuse history and obesity, the association between abuse history and outcomes after bariatric surgery is not well-established. We aimed to summarize the current literature examining this relationship, as well as provide clinical recommendations to optimize postoperative outcomes.

METHODS

PubMed and SCOPUS databases were queried to identify relevant published studies.

RESULTS

Overall, 20 studies were included. Rates of the various types of abuse reported in the bariatric surgery population varied widely across studies, as did the methodology used to assess it. The majority of studies found no significant associations between abuse history and postoperative weight loss outcomes. The literature examining the relationship between abuse history and postoperative psychiatric outcomes was less conclusive.

CONCLUSIONS

Most current evidence demonstrates that abuse history is not associated with weight loss outcomes after bariatric surgery. Literature on postoperative psychiatric outcomes is mixed, and more robust studies are needed to further investigate the relationship between abuse history and postoperative psychiatric outcomes. Importantly, abuse history should not preclude patients from undergoing bariatric surgery. Of note, patients may benefit from careful monitoring for emotional distress and worsening of psychiatric comorbidities after surgery and psychiatric counseling and treatment when indicated.

Feasibility of Food FARMacia: Mobile Food Pantry to Reduce Household Food Insecurity in Pediatric Primary Care

Despite recommendations for systematic food insecurity screening in pediatric primary care, feasible interventions in clinical settings are lacking. The goal of this study was to examine reach, feasibility, and retention in Food FARMacia, a pilot clinically based food insecurity intervention among children aged <6 years. We examined electronic health record data to assess reach and performed a prospective, longitudinal study of families in Food FARMacia (May 2019 to January 2020) to examine attendance and retention. We used descriptive statistics and bivariate analyses to assess outcomes. Among 650 pediatric patients, 172 reported household food insecurity and 50 registered for Food FARMacia (child mean age 22 ± 18 months; 88% Hispanic/Latino). Demographic characteristics of Food FARMacia participants were similar to those of the target group. Median attendance rate was 75% (10 sessions) and retention in both the study and program was 68%. Older child age (retention: age 26.7 ± 18.7 months vs. attrition: age 12.1 ± 13.8 months, p = 0.01), Hispanic/Latino ethnicity (retention: 97% vs. attrition: 69%, p < 0.01), and larger household size (retention: 4.5 ± 1.1 vs. attrition: 3.7 ± 1.4, p = 0.04) correlated with retention. A clinically based mobile food pantry pilot program and study reached the target population and were feasible.

Addressing the biological embedding of early life adversities (ELA) among adults through mindfulness: Proposed mechanisms and review of converging evidence

Early life adversities (ELA) are prevalent and have a profound and adverse impact across the lifespan, including on age-related health outcomes, yet interventions to remediate its adverse impact are scarce. This paper presents evidence for mindfulness training to reduce the elevated mental and physical health risks linked to ELA among adults by targeting biological mechanisms of ELA leading to these adverse health outcomes. We first provide a brief overview of ELA, its adverse health impacts, and mechanisms that might be responsible. Next, we review converging evidence that demonstrates that mindfulness training influences key biological pathways involved in ELA-linked negative health consequences, including (a) brain networks involved in self-regulation, (b) immunity and inflammation, (c) telomere biology, and (d) epigenetic modifications. Further, we review preliminary evidence from mindfulness-based trials that focused on populations impacted by ELA. We discuss limitations of this review and provide recommendations for future research. If effective, a mindfulness-based approach could be an important public health strategy for remediating the adverse mental and physical health consequences of ELA.

Association between Self-Reported Childhood Difficulties and Obesity and Health-Related Behaviors in Adulthood-A Cross-Sectional Study among 28,047 Adults from the General Population

The aim of the present study was to examine the associations between self-reported childhood difficulties, weight status, and lifestyle behaviors among a representative sample of Norwegian adults. This cross-sectional study included 28,047 adults (>18 years old) living in southern Norway. A self-report questionnaire was used to assess information about the overall quality of the respondents’ childhood retrospectively in addition to current weight status and current lifestyle behaviors. Multivariable logistic regression models adjusted for gender, age, and educational level showed that evaluating childhood as difficult was associated with increased odds of obesity (OR: 1.29; 95% CI; 1.16–1.44) in adulthood. Moreover, a difficult childhood was associated with increased odds of unhealthy lifestyle behaviors in adulthood, including low consumption of fruit and berries (1.21; 1.09–1.34) and fish (1.43; 1.30–1.57), high consumption of sugar-sweetened beverages (1.30; 1.14–1.48), low level of physical activity (1.10; 1.01–1.21), smoking cigarettes (1.78; 1.61–1.97), and using smokeless tobacco (1.20; 1.07–1.36). Overall, results from the present study suggest that experiencing childhood as difficult is associated with an increased risk of obesity and a range of unhealthy lifestyle behaviors in adulthood. Thus, our findings highlight the importance of identifying and providing support to children in difficult life circumstances in addition to customized and targeted public health efforts in adulthood.

Childhood Abuse-Related Weight Gain: An Investigation of Potential Resilience Factors

INTRODUCTION

Childhood physical, sexual, and emotional abuse are linked to adult obesity, and little is known about what protective factors might mitigate this association.

METHODS

Data from female (n=4,247) and male (n=1,982) participants in the longitudinal Growing Up Today cohort study from 1996 to 2013 were used to examine whether factors found to promote mental health resilience after abuse also operate as buffers (modifiers) of the abuse-weight status association. At ages 20-25 years, participants were asked about their history of child abuse before age 18 years. Potential resilience factors (modifiers) included childhood family SES, neighborhood safety, supportive relationships with adult nonfamily members, quality of maternal relationship, family structure, religious service attendance, and prayer/meditation. Associations between child abuse and BMI at ages 25-32 years were modeled using linear regression, adjusted for sociodemographic variables and baseline BMI. Potential modifiers were tested with interaction terms. Analyses were run in 2019-2020.

RESULTS

Severe abuse was associated with 0.9 kg/m² (95% CI=0.5, 1.2) higher adult BMI than no abuse, corresponding to a 46% increased risk of obesity (95% CI=1.28, 1.67). Less severe abuse was not significantly associated with BMI (β=0.1, 95% CI= -0.2, 0.4). There were no significant interactions between modifiers and abuse.

CONCLUSIONS

Factors previously found to promote resilience to mental health sequelae after abuse did not modify the association of severe child abuse with higher weight status.

Negative affect, childhood adversity, and adolescents' eating following stress

Obesity commonly emerges by adolescence and is associated with serious health consequences. Emotional eating (consuming calories, fats, and sugars in response to negative affect) may promote obesity; however, evidence is mixed as to whether negative affect increases obesogenic eating. Early-life adversity may shape malleable neurobiological systems that govern inhibitory control, physiological regulation, coping strategies, and eating behavior, contributing to greater obesogenic eating in response to negative affect. Therefore, this study tested whether childhood adversity moderates the association between negative affect and food consumption in a diverse sample of female adolescents. After completing a childhood adversity assessment, 157 female adolescents (13-17 years; 28.7% African American, 39.5% Hispanic/Latina, 31.8% Non-Hispanic White) rated their negative affect in response to a standard social stress paradigm before consuming a buffet lunch, which was evaluated for calories, added sugars, and solid fats consumed. Results did not support that negative affect exerted a main effect on eating behavior. However, negative affect and childhood adversity interacted to predict calories and solid fats consumed, such that negative affect was associated with more obesogenic eating for those with high adversity exposure but not for those with low adversity exposure. Adversity and affect did not interact to predict added sugars consumed. Findings support that eating patterns in response to negative affect may differ by childhood adversity history. Reducing children's adversity exposure and bolstering emotion regulation techniques for adolescents who have been exposed to adversity may provide pathways to protect health and well-being by reducing maladaptive eating patterns.

Adverse childhood experiences in relation to mood-, weight-, and eating-related outcomes in emerging adulthood: Does self-compassion play a buffering role?

BACKGROUND

Adverse childhood experiences (ACEs) are associated with a range of health problems, yet protective factors such as self-compassion may help buffer these associations.

OBJECTIVE

This study examined associations of distinct patterns of ACEs with depressive symptoms, body mass index (BMI), and disordered eating symptoms and investigated self-compassion as a potential protective factor.

PARTICIPANTS AND SETTING

Data from a diverse sample of 1440 emerging adults (M_age = 22.2 years; 53.7% female; 80.3% with race/ethnicity other than non-Hispanic white) came from the population-based EAT 2018 (Eating and Activity over Time) study.

METHODS

Seven types of ACEs were retrospectively self-reported and used as model indicators in latent class analysis to identify patterns of ACEs. Self-compassion, depressive symptoms, height and weight (to calculate BMI), and disordered eating symptoms were also assessed. Demographic-adjusted regression models were conducted.

RESULTS

Three latent classes emerged: "low ACEs" (66.5% of the sample), "household dysfunction" (24.3%), and "household dysfunction and abuse" (9.1%). Compared to participants in the "low ACEs" class, participants in either latent class involving household dysfunction demonstrated higher levels of depressive and disordered eating symptoms. Participants in the "household dysfunction and abuse" class also had higher BMI. Associations differed by self-compassion for depressive symptoms (p_interaction = 0.01), BMI (p_interaction = 0.03), and disordered eating symptoms (p_interaction = 0.005), such that associations for latent classes characterized by ACEs were weaker with higher levels of self-compassion.

CONCLUSIONS

These findings suggest self-compassion may act as a buffer against adverse mood-, weight-, and eating-related outcomes in the face of adversity and therefore may be an important intervention target.
