Purpose of Review Binge eating is a transdiagnostic symptom that disproportionately affects females. Sexually dimorphic gonadal hormones (e.g., estradiol, testosterone) substantially impact eating behavior and may contribute to sex differences in binge eating. We examine recent evidence for the role of gonadal hormones in binge eating risk across development.Recent Findings Both organizational (long-lasting impact on the central nervous system (CNS)) and activational (transient influences on the CNS) hormone effects may contribute to sex differences in binge eating. Gonadal hormones also impact within-sex variability in binge eating, with higher estradiol levels in females and higher testosterone levels in males protective across development. Emerging evidence suggests that the impact of gonadal hormones may be greatest for people with other risk factors, including genetic, temperamental (e.g., high negative affect), and psychosocial (e.g., exposure to weight-based teasing) risk. Summary Gonadal hormones contribute to sex differences and within-sex variability in binge eating across development.

Objective Our goal was to illuminate associations between specific characteristics of under‐resourced neighborhoods (i.e., socioeconomic deprivation, danger) and specific aspects of parenting (e.g., parental praise, parental nurturance, harsh parenting, and parental control). Background Prior work has highlighted associations between level of neighborhood disadvantage and the parenting of its residents. However, this work has yet to clarify the specific characteristics of the neighborhood or the types of parenting involved. Method Exhaustive modeling analyses were conducted in a sample of 1030 families of twins (average age 8 years; 51% male, 49% female; the racial composition was 82% White, 10% Black, 1% Asian, 1% Indigenous, 6% multiracial) from the Twin Study of Behavioral and Emotional Development in Children. Neighborhood and parenting were assessed using multiple informants and assessment strategies (neighborhood informants, family informants, administrative data, and videotaped parent–child interactions). Results Neighborhood socioeconomic deprivation (i.e., limited institutional and economic structural resources) demonstrated small but consistent negative associations with positive parenting behaviors and maternal control, but not with negative parenting behaviors. Neighborhood danger (i.e., recorded crime, fear of crime, exposure to community violence), by contrast, demonstrated weaker associations with parenting that dissipated once we controlled for overlap with socioeconomic deprivation. Conclusion Danger and socioeconomic deprivation do not function as interchangeable characteristics of under‐resourced neighborhoods, at least in terms of their association with positive parenting. Future studies should identify the specific mechanisms through which neighborhood socioeconomic deprivation is associated with less nurturing parenting.

Despite growing recognition of the importance of workforce diversity in health care, limited research has explored diversity among eating disorder (ED) professionals globally. This multi-methods study examined diversity across demographic and professional variables. Participants were recruited from ED and discipline-specific professional organizations. Participants’ (n = 512) mean age was 41.1 years (SD = 12.5); 89.6% (n=459) of participants identified as women, 84.1% (n = 419) as heterosexual/straight, and 73.0% (n = 365) as White. Mean years working in EDs was 10.7 years (SD = 9.2). Qualitative analysis revealed three themes resulting in a theoretical framework to address barriers to increasing diversity. Perceived barriers were the following: “stigma, bias, stereotypes, myths”; “field of eating disorders pipeline”; and “homogeneity of the existing field.” Findings suggest limited workforce diversity within and across nations. The theoretical model suggests a need for focused attention to the educational pipeline, workforce homogeneity, and false assumptions about EDs, and it should be tested to evaluate its utility within the EDs field.

Longitudinal data are needed to examine effects of the COVID-19 pandemic on disordered eating. We capitalized on an ongoing, longitudinal study collecting daily data to examine changes in disordered eating symptoms in women across 49 days that spanned the time before and during the COVID-19 outbreak in the United States. Women from the Michigan State University Twin Registry (N = 402) completed daily questionnaires assessing a range of symptoms (e.g., binge eating, weight/shape concerns, liking/wanting of palatable food (PF) and whole foods, hunger). Dates of the first US COVID-19 case, first case in each participant's state, and onset of the initial stay-at-home orders (SHOs) were used to categorize women into those who completed all daily assessments prior to, during, or after these dates. We used mixed linear models and specification-curve analysis to examine between-person (i.e., differences between women assessed before vs during/after COVID-19) and within-person (i.e., changes in symptoms from days before to days after the dates) effects of the pandemic. Results showed significantly higher levels of binge-related pathology (e.g., odds of binge eating, liking/wanting of PF) in women who completed assessments during/after COVID-19 events, and significantly increased liking/wanting of PF in the days following the pandemic onset. By contrast, minimal between-or within-person differences were observed for other variables, including weight/shape concerns, compensatory behaviors, hunger, or liking/wanting whole foods. Overall, results suggest a specific effect of the pandemic on binge-related phenotypes in women. General Scientific SummaryThis study shows that the onset of the COVID-19 pandemic in the United States was associated with increased binge-eating pathology in women. The effects appear to be specific to binge eating and not present for other types of symptoms including body weight and shape concerns, compensatory behaviors, or overall levels of eating disorder symptoms.
