Are child maltreatment and intimate partner violence associated with adult disordered eating?

OBJECTIVE: Disordered eating is one of the most prevalent mental health concerns (Galmiche et al., 2019, Quick & Byrd-Bredbenner, 2013, Neumark-Sztainer et al., 2006). Studies show that child maltreatment increases the likelihood of disordered eating symptoms in adulthood (Caslini et al., 2016, Hazzard et al., 2019). However, these studies overlook abuse experiences later in life, such as intimate partner violence which may also be a significant contributing factor (Bundock et al., 2013). The proposed study will help identify whether childhood maltreatment and IPV are independent predictors and/or if the combination of the two are synergistic risk factors for adult disordered eating. METHOD: We use data from 14,332 people from Wave III of the National Longitudinal Study of Adolescent to Adult Health (Add Health). Participants completed questionnaires assessing child maltreatment, intimate partner violence, and disordered eating symptoms. We will perform a series of logistic regression models to examine a) whether child maltreatment and intimate partner violence are independently associated with disordered eating and b) whether exposure to the combination of both child maltreatment and intimate partner violence is associated with worse outcomes for adult disordered eating compared to exposure to only one or none at all. We also propose a supplemental analysis to establish the robustness of these effects when accounting for the highest parental education, federal poverty percentage level, race/ethnicity, gender, and age. PUBLIC SIGNIFICANCE: Disordered eating is a serious mental health concern, especially in an emerging adult population. Child maltreatment is consistently associated with disordered eating in adulthood. However, the independent or synergistic role of more recent abuse experiences, such as intimate partner violence, remains largely unknown. The proposed study provides insight into how both childhood abuse and intimate partner violence may be associated with disordered eating independently or in combination.

Romantic relationship distress, gender, socioeconomic status, and inflammation: A preregistered report.

Poor quality romantic relationships increase risk for health problems; elevated systemic inflammation is one promising underlying mechanism. This registered report utilized data from 3 publicly available datasets with large sample sizes (Add Health, MIDUS, NSHAP) to test this possibility. An internal meta-analysis across all 3 studies determined that romantic relationship distress was unrelated to inflammation (assessed via C-Reactive Protein levels). In addition, this link was not moderated by gender, socioeconomic status (SES), or the combination of gender and SES.

Threats to Belonging, Immune Function, and Eating Behavior: an Examination of Sex and Gender Differences.

PURPOSE OF REVIEW: The first goal of this review is to discuss the evidence linking belonging threats to immune function and food intake. The second goal is to evaluate whether the links among belonging threats, immune function, and eating behavior differ based on gender. RECENT FINDINGS: Threats to belonging are linked to elevated herpesvirus antibody titers, dysregulated appetite-relevant hormones, and increased food consumption. Furthermore, these relationships are largely consistent for both men and women. Threats to belonging are also linked to elevated inflammation. However, some studies showed that these effects were stronger among women, others demonstrated that they were stronger among men, and others determined that the links were consistent for men and women. Understanding why belonging threats are inconsistently linked to inflammation across men and women is an important next step. We conclude the review with four concrete recommendations for researchers studying belonging threats, immune function, and eating behavior.
