An update on the prevalence of eating disorders in the general population: a systematic review and meta-analysis

Abstract

Objective To update the prevalence of eating disorders in the general population before 2021 and to analyze the distribution characteristics at different times and in different regions and sexes, as well as the diagnostic criteria. Methods Based on the method from a previous report by the authors, studies were identified from the following databases: PubMed/Medline, PsycINFO, ISI Web of Knowledge, Ovid and the 4 most important Chinese databases. Articles in English and Chinese before 2021 were retrieved. The data retrieved at this time were pooled with the data from a previous report for analyses. Results Thirty-three studies were identified, which included 18 studies supplemented in this retrieval. The pooled lifetime and 12-month prevalence of eating disorders were 0.91% (95% CI, 0.48–1.71) and 0.43% (95% CI, 0.18–0.78), respectively. The pooled lifetime and 12-month prevalence of the subgroup EDs (any), which covers all types of eating disorders, were 1.69% and 0.72%, respectively. The lifetime prevalence of AN, BN and BED was 0.16% (95% CI, 0.06–0.31), 0.63% (95% CI, 0.33–1.02) and 1.53% (95% CI, 1.00–2.17), respectively. The lifetime prevalence of EDs in Western countries was 1.89%, and was high at 2.58% in females. Prevalence studies using DSM-5 criteria were scarce. Conclusions The prevalence of eating disorders might be underestimated thus far. Not all types of EDs were included in a majority of epidemiological surveys, and the prevalence rates of the new types of EDs were significantly higher. Eating disorders were especially common in Western countries and in females. New diagnostic criteria should be used to comprehensively assess all types of eating disorders. Level of evidence 1, systematic review and meta-analysis.

Food Addiction, Saturated Fat Intake, and Body Mass Index in Peruvian Adults: A Cross-Sectional Survey

“…In fact, overweight or obese women have a significantly higher rate of food addiction compared to men [29]. is confirms the fact that eating disorders are more common among women than men [32]. However, larger studies in different populations are suggested to confirm the findings of the present study.…”

Adaptation and validation of the Caregiver Burden Inventory in Eating Disorders

“…Several different assessment tools that aim to measure Caregiver Burden (CB) are available internationally, among which the Caregiver Burden Inventory (CBI) is probably Introduction Eating Disorders (EDs) are complex mental disorders de ned by disturbed eating behaviours, distorted beliefs, and extreme concerns about food, eating and body image, shape or weight. The prevalence of these conditions is rising in many countries and recent studies suggest that EDs are not rare in the general population [1,2]. Their association with decreased quality of life, increased risk of depression and substance abuse has been shown in several studies [1].…”

A review on association and correlation of genetic variants with eating disorders and obesity

“…Eating disorders can be categorized into a class of mental illnesses that could result in numerous somatic and psychiatric complications and have penchant to perturb living quality as well as mortality in some cases. This psychiatric condition has increasingly been able to seek attention among world health fraternities over the past 20 years [1].
