Poor quality romantic relationships increase risk for health problems; elevated systemic inflammation is one promising underlying mechanism. This registered report utilized data from three publicly available data sets with large sample sizes (Add Health, MIDUS, NSHAP) to test this possibility. An internal metaanalysis across all three 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 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.
ObjectiveDisordered 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.MethodWe 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 SignificanceDisordered 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
