Child maltreatment and eating disorders are significant public health problems. Yet, to date, research has focused on the role of child physical and sexual abuse in eating-related pathology. This is despite the fact that globally, exposure to emotional abuse, emotional neglect and intimate partner violence are the three of the most common forms of child maltreatment. The objective of the present study is to systematically identify and critically review the literature examining the association between child emotional abuse (EA), emotional neglect (EN), and exposure to intimate partner violence (IPV) and adult eating-disordered behavior and eating disorders. A systematic search was conducted of five electronic databases: Medline, Embase, PsycINFO, CINAHL, and ERIC up to October 2015 to identify original research studies that investigated the association between EA, EN and children’s exposure to IPV, with adult eating disorders or eating-disordered behavior using a quantitative research design. Database searches were complemented with forward and backward citation chaining. Studies were critically appraised using the Quality in Prognosis Studies (QUIPS) tool. A total of 5556 publications were screened for this review resulting in twenty-three articles included in the present synthesis. These studies focused predominantly on EA and EN, with a minority examining the role of child exposure to IPV in adult eating-related pathology. Prevalence of EA and EN ranged from 21.0% to 66.0%, respectively. No prevalence information was provided in relation to child exposure to IPV. Samples included predominantly White women. The methodological quality of the available literature is generally low. Currently, the available literature precludes the possibility of determining the extent to which EA, EN or child exposure to IPV have independent explanatory influence in adult eating-related pathology above what has been identified for physical and sexual abuse. While a large proportion of adults with eating disorders or eating-disordered behavior report EA, EN, or child exposure to IPV , there is a paucity of high-quality evidence about these relationships.

Conduct a meta-analysis documenting healthcare service utilization rates for pediatric (148,000 child and adolescent eating disorder-related visits to >300 health settings across 15 countries were included (mean age 12.7 [SD 4.1] years; 87% girls). There was strong evidence of an increase in healthcare utilization for EDs during the pandemic (rate ratio [RR] 1.54, 95%CI 1.38-1.71). Moderator analysis revealed larger rate increases among girls (RR 1.48, 95%CI 1.28-1.71) compared to boys (RR 1.24, 95%CI 1.06-1.45) and adolescents (≥12 to 19 years) (RR 1.53, 95%CI 1.29-1.81) compared to children (RR 0.87, 95%CI 0.53-1.43). Moderator analysis demonstrated strong evidence of increased utilization of emergency department (RR 1.70, 95%CI 1.48-1.97), inpatient (RR 1.56, 95%CI 1.33-1.84), and outpatient services (RR 1.62, 95%CI 1.35-1.95), as well as strong evidence of increased rates of anorexia nervosa (RR 1.48, 95%CI 1.24-1.75). Healthcare utilization for pediatric EDs increased substantially during the COVID-19 pandemic, particularly among girls and adolescents. It is important to continue to monitor if changes in healthcare utilization associated with acute pediatric mental distress are sustained beyond the COVID-19 pandemic.

Objective: To systematically review and evaluate the efficacy of eating disorder focused family therapy (FT‐ED) in comparison to all other forms of psychotherapy for children and adolescents with anorexia nervosa. A secondary aim is to assess the relative efficacy of different variations of FT‐ED (e.g., shorter vs. longer dose, parent‐focused).Methods: A search with relevant terms was systematically conducted on four databases. Twenty‐three publications across 18 randomized controlled trials met inclusion criteria. Outcomes of interest included variables related to weight, eating psychopathology, and remission status. Study quality was assessed, and data were extracted by two independent researchers.Results: Adolescents receiving FT‐ED gained significantly more weight by the end of treatment in comparison to those receiving individual psychotherapy. FT‐ED that was delivered just to parents or to parents and child separately offered preferable weight outcomes and rates of recovery at the end of treatment in comparison to conjoint FT‐ED. No other outcomes tested in the meta‐analysis were statistically significant at the end of treatment or follow‐up.Discussion: Currently available data suggest the use of FT‐ED in its conjoint or separated/parent focused format is the best outpatient treatment option for adolescents with anorexia nervosa when immediate weight gain is paramount. The variability of outcome measurement, including the tools used and timepoints chosen, limit comparison among no more than a handful of studies. The field would benefit from the standardization of measurement and reporting guidelines for future clinical trials.Trial Registration: PROSPERO number: CRD42023396263.

With technological advances, the creation and distribution of child sexual abuse material (CSAM) has become one of the fastest growing illicit online industries in the United States. Perpetrators are becoming increasingly sophisticated and exploit cutting-edge technology, making it difficult for law enforcement to investigate and prosecute these crimes. There is limited research on best practices for investigating cases of CSAM. The aim of this research was to understand challenges and facilitators for investigating and prosecuting cases of CSAM as a foundation to develop best practices in this area. To meet these objectives, qualitative interviews and focus groups were conducted with participants throughout the western United States. Two major themes arose from this research: Theme 1: Challenges to investigating and prosecuting CSAM; and Theme 2: Facilitators to investigating and prosecuting CSAM. Within Theme 1, subthemes included technology and internet service providers, laws, lack of resources, and service provider mental health and well-being. Within Theme 2, subthemes included multidisciplinary teams and training. This research is a first step in understanding the experiences of law enforcement and prosecutors in addressing CSAM. Findings from this study can be used to support the development of best practices for those in the justice system investigating and prosecuting CSAM.

The assessment and diagnosis of atypical anorexia nervosa (AAN) is an ongoing challenge for clinicians. This study aims to examine psychological morbidity and exposure to childhood adversity in adolescents with AAN compared to adolescents with anorexia nervosa, restricting type (AN-R). This registry-based study compared 42 adolescents with AAN to 79 adolescents with AN-R on a variety of psychosocial measures at the time of presentation to a specialized eating disorder program. In contrast to AN-R, adolescents with AAN had more severe drive for thinness (p =.011), body dissatisfaction (p =.038), and lower quality of life (p =.047), but had better global functioning (p =.032). Adolescents who had high Adverse Childhood Experiences (ACE) Questionnaire scores (ACE score ≥ 4) had over 5 times higher odds of having AAN than those who did not have high ACE scores (p =.008). There was no significant difference between groups on measures of low self-esteem and non-accidental self-injury. Adolescents with AAN presented with similar or more severe psychosocial distress compared to their peers with AN-R across a majority of the measures. The findings highlight the need to address trauma, body-related difficulties, and quality of life in the assessment and treatment of adolescents with AAN.
