Sex-dependent associations of childhood neglect and bodyweight across the life span

Adverse Childhood Experiences and Risk of Abnormal Body Mass Index: A Global Systematic Review and Meta-Analysis

(1) Objectives: The impact of abnormal body mass index (BMI) on health is extensive, and various risk factors contribute to its effects. This study aimed to examine the association between adverse childhood experiences (ACEs) and BMI categories, including underweight, overweight, obesity, severe obesity, and morbid obesity; (2) Methods: Three databases were searched: Web of Science, PubMed, and Scopus. Manual searches were conducted using Google Scholar and ResearchGate. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between ACEs and BMI. A random-effects model was used to combine the ORs and CIs across studies; (3) Results: This meta-analysis included 71 studies. The pooled ORs for the relationship between ACEs and obesity was 1.42 (95% CI: 1.24-1.63, Z = 4.96, p < 0.001), indicating a significant association. ACEs showed a positive association with overweight (OR = 1.16, 95% CI: 1.06-1.27, Z = 3.24, p = 0.001). Specifically, ACEs ≥ 4 were strongly associated with obesity (OR = 2.06, 95% CI: 1.27-3.36, Z = 2.90, p = 0.004). Sexual abuse was also found to be significantly associated with obesity (OR = 1.46, 95% CI: 1.29-1.65, Z = 5.98, p < 0.001); (4) Conclusion: This study finds that individuals who have experienced ACEs are more likely to have a higher BMI in adulthood. Therefore, ACEs should be considered a factor associated with abnormal BMI.

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.

The association of depressive symptoms and body weight change in midlife - Results from the Gutenberg Health Study in Germany

BACKGROUND

The present study aimed to investigate how depressive symptoms affect bodyweight change (gain and loss), and how this association is intertwined with other psychosocial and biomedical factors in the adult general population.

METHODS

In a population-based, prospective, observational single-center cohort study in the Rhine-Main-Region, Germany (Gutenberg Health Study GHS) with N = 12,220 participants, we analyzed baseline and five year follow-up data with logistic regressions separately for bodyweight gain and loss (vs. stable bodyweight).

RESULTS

Overall, 19.8 % of participants gained bodyweight of at least 5 %. More female participants were affected than male participants (23.3 % vs. 16.6 %). Regarding weight loss, overall, 12.4 % lost >5 % of bodyweight; participants were more often female than male (13.0 % vs. 11.8 %). Depressive symptoms at baseline were associated with weight gain (OR = 1.03, 95 % CI = 1.02-1.05). In models controlling for psychosocial and biomedical factors, female gender, younger age, lower socioeconomic status and smoking cessation were associated with weight gain. In weight loss, there was no overall significant effect of depressive symptoms (OR = 1.01 [0.99; 1.03]). Weight loss was associated with female gender, diabetes, less physical activity, and higher BMI at baseline. Only in women, smoking and cancer were associated with weight loss.

LIMITATIONS

Depressive symptoms were assessed via self-report. Voluntary weight loss cannot be determined.

CONCLUSIONS

Significant weight change frequently occurs in middle to old adulthood resulting from a complex interplay of psychosocial and biomedical factors. Associations with age, gender, somatic illness and health behavior (e.g. smoking cessation) provide important information for the prevention of unfavorable weight change.

Epistemic trust and personality functioning mediate the association between adverse childhood experiences and posttraumatic stress disorder and complex posttraumatic stress disorder in adulthood

Background

Adverse childhood experiences (ACEs) are associated with posttraumatic and complex posttraumatic stress disorder symptoms in adulthood (PTSD/cPTSD), as well as reduced epistemic trust (trust in the authenticity and personal relevance of interpersonally transmitted information) and impaired personality functioning. The present work aims to investigate the predictive value of epistemic trust-the capacity for social learning-on the mediating effect of personality functioning in the association of ACEs and PTSD/cPTSD.

Methods

We conducted structural equation modeling (SEM) based on representative data of the German population (N = 2,004). Personality functioning (OPD-SQS) was applied as a mediator between ACEs and PTSD/cPTSD (ITQ), while epistemic trust (ETMCQ) was added as predictor for OPD-SQS. TLI, CFI, and RMSEA (95%-CI) determined the models' fit.

Results

N = 477 (23.8%) participants reported at least one ACE and n = 218 (10.9%) reported ≥4 ACEs. Fit indices were good for both PTSD (TLI = 0.96; CFI = 0.99; RMSEA = 0.06; 95%CI: 0.041-0.078) and cPTSD (TLI = 0.96; CFI = 0.99; RMSEA = 0.06; 95%CI: 0.043-0.081). ACEs were significantly associated with cPTSD (β = 0.44, p < 0.001) and PTSD (β = 0.29, p < 0.001), explaining 20 and 8% of its variance. Adding personality functioning as a mediator increased the explained variance of cPTSD and PTSD to 47 and 19% while the direct association between ACEs and cPTSD/PTSD decreased (β = 0.21/β = 0.17), thus, indicating a partial mediation. Including epistemic trust substantially increased the explained variance for personality functioning (41%) compared to ACEs as a single predictor (16%).

Conclusion

We add to previous research emphasizing the association between ACEs and PTSD/cPTSD symptoms. Offering insights on underlying mechanisms, we show that epistemic trust and personality functioning are relevant mediators. Since both are modifiable by psychotherapy, knowledge about the role of these constructs can inform research on psychotherapeutic interventions and prevention.

Personality functioning as a mediator of adult mental health following child maltreatment

BACKGROUND

The broad range of adverse health outcomes following child maltreatment (child maltreatment) underscores the need to investigate shared trajectories that contribute to associated physical and mental health problems. Previous research focused on different mechanisms, such as emotion regulation or attachment. In the present study, we propose personality functioning, comprising self- and interpersonal regulation and perception, to mediate between child maltreatment and mental and physical health.

METHODS

In a German representative sample (N = 2,508), we assessed remembered child maltreatment, levels of personality functioning, and different health outcomes in adulthood, namely somatic symptoms, general mental distress, and body dysmorphic concern. We conducted path analyses to investigate mediation effects in the total sample as well as in female and male subsamples.

RESULTS

Child maltreatment significantly predicted the assessed health outcomes and showed significant associations with lower levels of personality functioning. Personality functioning partially mediated all health outcomes assessed by significant indirect effects and lowered direct effects of child maltreatment on health outcomes. An exploratory analysis of different facets of personality functioning revealed a pronounced impact of identity perception and self-reflective capacities in mediating between child maltreatment and physical and mental health. Comparable results were found in female and male participants.

LIMITATIONS

Major limitations of the study are the reliance on cross-sectional data and the use of a screening measure to assess experienced child maltreatment.

CONCLUSION

Personality functioning may represent a transdiagnostic link to different somatic and psychological symptoms in the aftermath of child maltreatment.

The relation between childhood adversity and adult obesity in a population-based study in women and men

Childhood maltreatment has been shown to relate to adult obesity. In this epidemiological study, we investigate the association between childhood maltreatment and waist-to-height-ratio (WHtR) in a sample of the German adult population, comprising of N = 2936 participants. WHtR, an indicator for risk of obesity, was the primary outcome. Childhood maltreatment was assessed by the Childhood Trauma Screener (CTS), which assesses emotional and physical neglect, abuse as well as sexual abuse. Cohort-data were harmonized and analyzed within DataSHIELD. We used multivariable regression models to estimate the association of childhood maltreatment and WHtR at different levels of adjustments for potential confounders. Overall childhood maltreatment was associated with a higher WHtR in both sexes (women: p = 0.004, men: p < 0.001); associations were no longer significant in women after adding socioeconomic variables, but remained significant in men (p = 0.013). Additionally, we were able to identify sex specific patterns for childhood maltreatment predicting the WHtR. Emotional neglect and abuse had stronger impacts on the WHtR in women than in men, whereas physical neglect and abuse had stronger impacts in men. To our knowledge, this is the first comprehensive population-based study testing various types of childhood maltreatment with WHtR in sex-, region- and weight-stratified analyses. Future studies in clinical populations are warranted to examine U-shaped correlations between increased WHtR and childhood maltreatment.

Gender-Dependent Associations of Anxiety and Depression Symptoms With Eating Disorder Psychopathology in a Representative Population Sample

Background: Evidence shows that anxiety and depressive disorders play an important role in eating disorder behavior. However, given the epidemiology of eating disorders, there is a need to investigate potentially gender-specific connections. Method: This study tested the associations of anxiety and depression symptoms with eating disorder symptoms and behaviors and explored whether they differed between men and women. Within a population-representative survey (N = 2,510; ages 14-94), participants completed measures of depression symptoms (PHQ-2), anxiety symptoms (GAD-2), and eating disorder symptoms (EDE-Q8). We conducted linear regression analyses of the EDE-Q8 sum score and General Linear Models on the three behaviors overeating, binge eating, and compensatory behaviors (self-induced vomiting/use of laxatives/excessive exercising). Results: Depression and anxiety symptoms were related to more eating disorder symptoms in men and women (irrespective of BMI, age, and income). The association of depression and eating disorder symptoms was slightly stronger in women. Overeating was more common in men and in depressed individuals, whereas compensatory behaviors were more common among anxious individuals, especially anxious women. Conclusion: The study extends previous research by using gender-specific methods in a representative sample. It indicates similarities and differences between men and women regarding disordered eating on a population level.

Suicide attempts in chronically depressed individuals: What are the risk factors?

Chronically depressed individuals have a high suicide risk. However, it is an open question whether previously observed risk factors for suicide attempts also apply to chronic depression or whether there are specific risk factors related to chronic-recurrent illness. We drew from a large group of chronically depressed individuals seeking psychotherapy to investigate demographic and psychological factors related to previous suicide attempts. Participants took part in the SCID and filled out established questionnaires. Among 368 chronically depressed individuals (68.7% women; M_age = 40.95 years), 75 participants (19.4%) reported previous suicide attempts. Men were more likely to have used violent methods. We tested the links of having attempted suicide with different variables using logistic regression analyses. Our findings corroborate previously observed risk factors (e.g. sexual abuse, personality disorders) and suggest other risk factors which could be especially relevant in chronic depression (e.g. depression severity, interpersonal problems, self-injurious behavior, and overall years of depression). Other risk factors from previous studies were not related to suicidal behavior within our sample (e.g. anxiety disorders, PTSD). Thus, mental health professionals should be aware that risk factors for suicidal behavior might vary between diagnosis groups and that chronic illness might be a risk factor in itself.
