Adverse experiences as predictors of maladaptive and adaptive eating: Findings from EAT 2018

Childhood maltreatment and the risk of eating disorders: a meta-analysis of observational studies

OBJECTIVE

The purpose of this systematic review and meta-analysis is to examine the relationship between childhood maltreatment as a variable of exposure and eating disorders as an outcome.

METHODS

PubMed, Web of Science, and Google Scholar were searched to find manuscripts related to the current research. The search was conducted up until October 2023 and limited to the English language. An odds ratio (OR) based on the random effects method was used to combine studies. One subgroup analysis was performed based on the type of eating disorder and another based on the type of childhood maltreatment.

RESULTS

Thirty eligible studies were recognized for this research. Childhood maltreatment was associated with a rate of eating disorders of more than double: OR 2.37 with 95% confidence interval (CI) 1.84-3.06 (P < 0.001; I2 = 92.6%). Childhood maltreatment was associated with anorexia nervosa (OR 1.89, 95% CI 1.47-2.42; Z = 5.03; P < 0.001; I2 = 0%), bulimia nervosa (OR 2.64, 95% CI 1.34-5.17; Z = 2.82; P = 0.005; I2 = 93.1%), and binge eating disorder (OR 1.76, 95% CI 1.38-2.26; Z = 4.52; P < 0.001; I2 = 80.2%).

CONCLUSION

The findings of this research showed that childhood maltreatment significantly increases the risk of eating disorders. Therefore, in understanding the mechanisms related to eating disorders, it is necessary to pay attention to the issue of the childhood living environment and the traumatic experiences of that time.

Associations of positive childhood experiences with binge-eating disorder characteristics and intuitive eating among college students

Childhood experiences encompass both adverse and positive childhood events. Adverse childhood experiences are positively associated with binge-eating disorder characteristics and inversely associated with intuitive eating in adults. However, to what extent positive childhood experiences (PCEs) are associated with binge-eating disorder characteristics and intuitive eating remains unclear. This study examined the associations of cumulative and individual PCEs with binge-eating disorder characteristics and intuitive eating among college students. Data were collected from 828 college students in 2022 (54.5% female, Mage 20.9 ± 2.6 years). PCEs were assessed using the Benevolent Childhood Experiences scale. Binge-eating disorder characteristics were assessed with the Questionnaire on Eating and Weight Patterns-5. Intuitive eating was assessed with the Intuitive Eating Scale-2. Associations of PCEs with binge-eating disorder characteristics and intuitive eating were examined using modified Poisson regressions and linear regressions. PCEs were cumulatively associated with binge-eating disorder characteristics and intuitive eating (p for trend <.05). College students in the low PCEs category (0-4 PCEs) had 1.37-1.92 times the prevalence of binge-eating disorder characteristics and had 3.89 points lower intuitive eating score than those in the high PCEs category (9-10 PCEs). Among the individual PCEs, intrapersonal PCE (i.e., feeling comfortable with oneself during childhood) was associated with both a lower prevalence of binge-eating disorder characteristics (aPR = 0.56-0.76) and a higher score of intuitive eating (adjusted β = 1.87, 95% CI = 1.28-2.46) after adjustment for sociodemographic variables. Findings from this study suggest that PCEs may play a role in eating behaviors of college students. Future studies with nationally representative samples should prospectively examine associations of PCEs with binge-eating disorder characteristics and intuitive eating and explore the underlying mechanisms of the associations between PCEs and eating behaviors.

Adverse childhood experiences and food insecurity in emerging adulthood: findings from the EAT 2010-2018 study

OBJECTIVE

Low childhood socio-economic status (SES) and adverse childhood experiences (ACE) are associated with poor health outcomes in adulthood. Determining how ACE may be linked to food insecurity among young people from socio-economically diverse households can inform health-protective strategies. This study examined if ACE are associated with food insecurity during the transition to adulthood and investigated prevalence differences across SES strata.

SETTING

Participants were recruited from twenty secondary schools in Minneapolis-St. Paul, Minnesota.

PARTICIPANTS

The analytic sample (n 1518) completed classroom surveys in 2009-2010 (mean age = 14·5 years) and follow-up surveys in 2017-2018 (mean age = 22·0 years).

DESIGN

Past-year food insecurity was reported at both time points, and ACE were reported at follow-up. Logistic regression models were used to estimate emerging adult food insecurity prevalence by ACE exposure; models were stratified by childhood SES (low, middle and high).

RESULTS

The adjusted prevalence of food insecurity was 45·3 % among emerging adults who reported three or more ACE compared with 23·6 % among those with one or two ACE and 15·5 % among those with no ACE (P < 0·001). All forms of ACE were related to an elevated prevalence of food insecurity in emerging adulthood. ACE-food insecurity associations were strongest for emerging adults from lower and middle SES households. Among emerging adults from low SES households, childhood experiences of emotional abuse and substance use by a household member were associated with the largest prevalence differences in food insecurity.

CONCLUSIONS

Findings suggest a need for trauma-informed services within food assistance programs to better serve individuals with a history of ACE.

Sex and ethnic/racial differences in disordered eating behaviors and intuitive eating among college student

Introduction

Eating behaviors encompass disordered eating behaviors (e.g., overeating, binge eating, and associated symptoms of binge eating) and intuitive eating. Certain disordered eating behaviors, including binge eating, are more prevalent among female and ethnic/racial-minority college students than male and/or non-Hispanic White college students. However, sex and ethnic/racial differences among college students with other disordered eating (e.g., associated symptoms of binge eating) and intuitive eating behaviors remain unclear.

Methods

In 2022, 887 college students (Mage = 20.9 ± 2.6 years) self-reported their sex, ethnicity/race, disordered eating behaviors (e.g., overeating, binge eating, associated symptoms of binge eating), and intuitive eating. To examine sex and ethnic/racial differences among these students, we used modified Poisson regressions for students who reported disordered eating and linear regressions for students who reported intuitive eating.

Results

Except for overeating, disordered eating behaviors were more prevalent among female [adjusted prevalence ratio (aPR) = 1.3-1.8] than male college students after adjusting for sociodemographic variables, whereas intuitive eating scores did not differ by sex. Across ethnic/racial groups, disordered eating was more prevalent among all ethnic/racial-minority college students (aPR = 1.2-2.3) than non-Hispanic White college students after adjusting for sociodemographic variables. Moreover, non-Hispanic Black or African American college students had higher intuitive eating scores than non-Hispanic White college students (adjusted β = 0.7, 95% CI = -0.2, 1.6).

Conclusion

In our sample, notable differences emerged in the prevalence of disordered eating behaviors and mean scores by sex and ethnicity/race, while differences in intuitive eating scores emerged based on ethnicity/race.

Associations among retrospective parenting styles, retrospective food parenting, and current eating behaviors in Chinese adults

The current study explored the relationships between retrospective parenting styles and food parenting in childhood (≤ 12 years old) and Chinese adults' current maladaptive and adaptive eating behaviors. We recruited 501 Chinese adults (50.30% men, aged 19-46 years). A set of questionnaires were used to measure retrospective parenting styles (i.e., emotional warmth, rejection, and overprotection), food parenting (i.e., parental concern, monitoring, pressure to eat, and restriction), and current maladaptive (i.e., disordered eating) and adaptive (i.e., intuitive eating) eating behaviors. Correlation and mediation analyses were employed to analyze these data. Results revealed that retrospective parenting styles and food parenting were significantly related to current maladaptive and adaptive eating behaviors in both Chinese men and women. Mediation analyses showed that higher retrospective parental warmth was related to higher retrospective parental concern which, in turn, was related to higher current disordered eating in men (indirect effect = 0.14, 95% CI 0.08, 0.24). Furthermore, higher retrospective parental overprotection was related to higher retrospective parental pressure to eat which, in turn, was related to higher current disordered eating in men (indirect effect = 0.06, 95% CI 0.01, 0.14). For women, higher retrospective parental warmth was associated with higher retrospective parental concern which, in turn, was associated with lower current intuitive eating in women (indirect effect = -0.04, 95% CI = -0.10, -0.01). Furthermore, higher retrospective parental overprotection was associated with higher retrospective parental concern which, in turn, was associated with lower current intuitive eating in women (indirect effect = -0.03, 95% CI = -0.08, -0.004). The findings indicate the importance of including childhood parenting styles and food parenting in future research and intervention of adults' current maladaptive and adaptive eating behaviors.

Adverse childhood experiences and disordered eating among middle-aged adults: Findings from the coronary artery risk development in young adults study

Adverse childhood experiences (ACEs) include childhood abuse, neglect, and household substance abuse. Childhood abuse is a risk factor for disordered eating (DEB). Less well established are associations of childhood neglect and household substance abuse with DEB, and little research has examined ACE associations with DEB in middle adulthood. The objective of this study was to examine associations between ACEs and DEBs among middle-aged adults and examine sex differences. ACEs prior to age 18 were retrospectively assessed in the Coronary Artery Risk Development in Young Adults study in 2000-2001 (N = 3340, ages 32 to 46). DEB outcomes (i.e., concerns about weight and shape, anxiety about eating or food, unhealthy weight control behaviors, chronic dieting, overeating, and binge eating) were assessed in 1995-1996 (ages 27 to 41). Modified Poisson regressions estimated risk ratios (RRs) for associations of a history of any ACE, each ACE, and cumulative ACEs with DEB outcomes. Among women, emotional abuse, physical neglect, and emotional neglect were each modestly associated with most DEBs (RRs = 1.21-1.35, 1.21-1.45, and 1.23-1.41 across DEBs, respectively) after adjustment for sociodemographic variables, BMI, and depressive symptoms. A cumulative ACE score was associated with all DEBs in a stepwise manner (p for trend ≤0.05) except concerns about weight and shape and overeating. Among men, emotional abuse was most consistently related to the majority of DEBs (RRs = 1.23-1.92); household substance abuse was modestly associated with overeating (RR = 1.26, 95% CI = 1.04-1.53). ACEs were cumulatively associated with unhealthy weight control behaviors, overeating, and binge eating (p for trend <0.01).
