Anorexia Nervosa-restricted type with obsessive traits in a pre-pubertal female: A case report

Research on feeding and eating disorders in India: A narrative review

Despite growing evidence of their prevalence, research on feeding and eating disorders (FEDs) in India has been sporadic. This narrative review aimed to summarize the research on FED in India and set priorities for future research and translation of evidence. An electronic search was conducted in the MEDLINE, PsycINFO, and Google Scholar databases to identify relevant English peer-reviewed articles from April 1967 to July 2023. The extracted data from these studies included author names, publication year, research location, type of intervention (for interventional studies), nature of comparator treatments, and main outcomes or findings. We found a rising trend in the prevalence of EDs in India. Adolescent age group, female sex, higher socioeconomic status, family history of mental illness or disordered eating, and borderline personality pattern were risk factors for EDs. For feeding disorders (FDs), childhood age group, malnutrition, pregnancy, psychosis, intellectual disability (ID), and obsessive-compulsive disorder (OCD) were putative risk factors. Both physical and psychiatric comorbidities were common in FEDs. Culture appears to exert a pathoplastic effect on symptom presentation in FEDs; an illustrative example is the documented nonfat phobic variant of anorexia nervosa (AN) in India. Research on management has focused on using assessment tools, investigations to rule out medical comorbidities, psychosocial and family-based psychotherapies, nutritional rehabilitation, pharmacotherapy, and neuromodulation approaches. Whereas the publication output on FEDs in India has increased over the last decade, it remains an under-researched area, with a striking paucity of original research. Future research priorities in FEDs include conducting country-wide registry-based studies to offer real-world insights, longitudinal research to identify culturally relevant risk factors, and developing brief, culturally sensitive diagnostic instruments for FEDs in the Indian context. This will help generate locally relevant epidemiological data on FEDs and inform treatment and prevention strategies.

Clinical profile of children and adolescents diagnosed with anorexia nervosa in Indian context

OBJECTIVE

This study was conducted to assess the trends observed in the prevalence pattern, clinical presentation, psychosocial profile and treatment profile of anorexia nervosa in children and adolescents who presented to a tertiary care child and adolescent psychiatry centre over a period of ten years.

METHODS

Case records of children and adolescents diagnosed with anorexia nervosa at the department of child and adolescent psychiatry from 1st April 2009-31 st March 2019 were obtained from the medical records department of the National Institute of Mental Health and Neurosciences (NIMHANS). Standardized data abstraction forms were developed and used for the purpose of this study. Pseudo-anonymization was done to ensure confidentiality and clinical characteristics of the sample were studied using frequency analysis and central tendencies.

RESULTS

Prevalence of anorexia nervosa in a clinic-based population is estimated to be 0.07% over the 10-year period. The mean age at presentation was 13.96 years (SD-2.3) and the male to female ratio was 1:12. The majority (80.8%) were admitted and only one patient (3.8%) received treatment on an outpatient basis. Two or more psychosocial stressors were associated with the onset of illness in 88.5% (n = 23) of the patients and dysfunctional family dynamics was noted to be a significant issue in the majority of cases. All the patients received pharmacotherapy and CBT-based individual therapy. The overall outcome was favourable based on the CGI-I scores.

CONCLUSIONS

Prevalence of anorexia nervosa in the clinic-based setting is rising in the Indian context. Sample characteristics are similar to those seen in the west. There is a huge demand-supply gap that calls for creating a service provider network to ensure community-based care.

Risk factors for anorexia nervosa and bulimia nervosa in Japan and compared to a U.S. sample

OBJECTIVE

This study provides the first systematic investigation of environmental exposure to putative psychosocial risk factors for eating disorders in individuals with AN and BN in Japan. It also provides a comparison of risk factors for the development of AN and BN in Japan versus the United States.

METHOD

Participants in Japan were 96 women with a current DSM-IV AN or BN primary diagnosis (AN, n = 60; BN, n = 36) and 57 women with no current psychiatric diagnosis (NC group). Participants in the United States were 137 women with a current DSM-IV AN or BN primary diagnosis (AN-U.S., n = 71; BN-U.S., n = 66). A standardized semi-structured interview retrospectively assessed exposure to risk factors prior to first symptom onset, which were analyzed using General Linear Model analyses.

RESULTS

Perfectionism and negative affectivity, family relationship issues, and, to a lesser degree, parental psychopathology predicted the emergence of AN and BN in Japan. Physical and sexual abuse and family eating and weight concerns were not significant risk factors in Japan. Compared to their respective diagnostic U.S. groups, the Japanese AN group reported higher levels of individual mental health factors and lower levels of family dieting and family overweight, and the Japanese BN group reported higher levels on individual mental health factors, lower exposure to problems with their parents, and lower exposure to family weight and eating concerns.

DISCUSSION

These country-specific data from Japan contribute to an increasingly nuanced and global understanding of risk factors for eating disorders.

Eating Disorders: An Overview of Indian Research

There has been sporadic research on eating disorders in India, with no published attempt to collate and summarize the literature landscape. Hence, the present narrative review aims to summarize Indian work related to eating disorders, discern current trends, and highlight gaps in research that will provide directions for future work in the area. Electronic search using the MEDLINE, Google Scholar, and PsycINFO databases was done to identify relevant peer-reviewed English language articles, in October 2018, using combinations of the following medical subject headings or free text terms: "eating disorders," "anorexia nervosa," "bulimia," "treatment," "epidemiology," "co-morbidity," "management," "medications," "behavioral intervention," and "psychosocial intervention." The data extracted from studies included details such as author names, year, from which of the states in India the work originated, type of intervention (for interventional studies), comparator (if any), and major outcomes. There is increasing research focused on eating disorders from India over the last decade, but it continues to be an under-researched area as evidenced by the relative paucity of original research. The cultural differences between east and west have contributed to variations in the presentation as well as challenges in the diagnosis. Hence, there is a need for the development of culturally sensitive instruments for diagnosis, as well as generating locally relevant epidemiological data about eating disorders from community and hospital settings.

Feeding and Eating Disorders in Children

This article provides an update based on recently published literature and expert consensus on the current state of knowledge regarding feeding and eating disorders in children aged 2 to 12 years. It covers the 6 main diagnostic categories-pica, rumination disorder, avoidant/restrictive food intake disorder, anorexia nervosa, bulimia nervosa, and binge eating disorder-discussing issues and findings specific to this age group. It highlights the need for ongoing research in a number of key areas, to include improved understanding of etiologic pathways, characterization of presenting disorders, and the development of standardized evidence-based assessment tools and treatment interventions.

Cultural trends and eating disorders

PURPOSE OF REVIEW

Culture has long been recognized as significant to the cause and expression of eating disorders. We reviewed the recent literature about recent trends in the occurrence of eating disorders in different cultures.

RECENT FINDINGS

While historically, eating disorders were conceptualized as primarily afflicting Caucasian adolescent or young adult women within high-income, industrialized Western Europe and North America, eating disorders are increasingly documented in diverse countries and cultures worldwide. This study highlights recent trends that reflect the changing landscape of culture and eating disorders: stabilization of the incidence of anorexia nervosa and possibly lower incidence rates of bulimia nervosa in Caucasian North American and Northern European groups; increasing rates of eating disorders in Asia; increasing rates of eating disorders in the Arab region; and increasing rates of binge eating and bulimia nervosa in Hispanic and Black American minority groups in North America.

SUMMARY

The changing face of eating disorders calls for a new conceptualization of culture in both the emergence and spread of eating disorders across the globe.
