Abstract

Objective: Disordered eating behaviors (DEBs) represent a significant public health issue, with childhood maltreatment emerging as a potential contributing factor. However, the longitudinal impact of maltreatment on the progression of disordered eating behaviors from adolescence to adulthood remains inadequately understood. This study aims to explore how childhood maltreatment influences the trajectory of disordered eating behaviors, focusing on potential moderating factors such as sociodemographic variables, race, and sex.

Methods: Data from Waves I-III of Add Health (ages 11-26) were used to assess DEB trajectories, with retrospective childhood maltreatment data collected in Wave IV. Repeated measures mixed-effects models accounted for intra-individual variability, adjusting for relevant covariates. Interaction effects between maltreatment subtypes and sociodemographic covariates (sex, race/ethnicity, income) were analyzed to examine how these intersections influenced DEB trajectories.

Results: Among the 15,363,384 participants, 49.2% experienced childhood maltreatment. Adjusted models indicated significant increases in DEBs over time, particularly between Waves II and III (β = 19.9, p < 0.001). Although physical abuse (β = 1.88, p = 0.1330), verbal abuse (β = -0.67, p = 0.4529), and sexual abuse by a parent (β = 1.59, p = 0.4204) were not significant predictors of worsening behaviors, stratified analyses revealed that low-income individuals exposed to non-familial sexual abuse demonstrated the steepest worsening of DEBs (β = 26.5, p = 0.0048). Interaction effects revealed that Asian or Pacific Islander participants experiencing verbal abuse, and low-income individuals exposed to non-familial sexual abuse demonstrated pronounced worsening of DEBs. We observed significant sex differences: males exhibited higher levels of worsening behaviors over time (β = -10.8, p < 0.0001).

Conclusion: Our findings suggest that sociodemographic characteristics (sex, race, income) may moderate the persistence of DEBs, underscoring the need for trauma-informed and tailored interventions. Addressing childhood adversity through public health, policy, and clinical efforts can help support those at highest risk. Future research should examine these trajectories beyond early adulthood and explore protective factors that may buffer against long-term DEB risk.

儿童虐待和饮食失调行为的纵向轨迹:社会人口统计学调节因子和行为特异性敏感性分析。
目的:饮食失调(DEBs)是一个重要的公共卫生问题,儿童虐待是一个潜在的促成因素。然而,从青春期到成年,虐待对饮食失调行为发展的纵向影响仍然没有得到充分的了解。本研究旨在探讨童年虐待如何影响饮食失调行为的轨迹,重点关注潜在的调节因素,如社会人口变量、种族和性别。方法:使用来自Add Health第I-III波(11-26岁)的数据来评估DEB轨迹,并使用第IV波收集的回顾性儿童虐待数据。重复测量混合效应模型考虑了个体内变异性,并对相关协变量进行了调整。我们分析了虐待亚型与社会人口学协变量(性别、种族/民族、收入)之间的相互作用,以检验这些交集如何影响DEB轨迹。结果:在15,363,384名参与者中,49.2%的人经历过童年虐待。调整后的模型显示,随着时间的推移,DEBs显著增加,特别是在第二波和第三波之间(β = 19.9, p)。结论:我们的研究结果表明,社会人口统计学特征(性别、种族、收入)可能会缓和DEBs的持续存在,强调需要创伤信息和量身定制的干预措施。通过公共卫生、政策和临床努力应对童年逆境,有助于支持风险最高的儿童。未来的研究应该在成年早期之后检查这些轨迹,并探索可能缓冲长期DEB风险的保护因素。

期刊介绍: Journal of Eating Disorders is the first open access, peer-reviewed journal publishing leading research in the science and clinical practice of eating disorders. It disseminates research that provides answers to the important issues and key challenges in the field of eating disorders and to facilitate translation of evidence into practice. The journal publishes research on all aspects of eating disorders namely their epidemiology, nature, determinants, neurobiology, prevention, treatment and outcomes. The scope includes, but is not limited to anorexia nervosa, bulimia nervosa, binge eating disorder and other eating disorders. Related areas such as important co-morbidities, obesity, body image, appetite, food and eating are also included. Articles about research methodology and assessment are welcomed where they advance the field of eating disorders.
