Abstract:   (314 Views)
Context: Eating disorders are among the deadliest psychiatric diseases that have become increasingly prevalent in different societies in recent years. Biological, social and psychological factors are involved in the emergence of different types of eating disorders. Several studies have been conducted by medical and non-medical researchers in Iran to estimate the prevalence of this disorder and its subcategories, which have been associated with different epidemiological methodologies and instruments and inconsistent results.
Objective: The aim of this study is to statistically analyze all available findings to determine the total estimate of the prevalence of eating disorders in the general population of Iran and to investigate the reasons for the heterogeneity in the results of previous studies.
Data Sources: Articles were collected by searching the databases of SID, Magiran, Irandoc, Iran Medex, PubMed and Google Scholar.
Study Selection: All studies evaluating the prevalence of eating disorders in any region of Iran from 1990 to the end of 2021 were included in the study. Articles that were irrelevant in terms of subject or methodology were excluded.
Data Extraction: Four researchers independently extracted the data of articles based on a pre- prepared list that included author name, study title, year of publication, journal name, city and population of the study, sample size, study instruments, and prevalence of eating disorder.
Results: The estimated point prevalence of any eating disorder in Iran was 22% (95% CI, 7- 38%). Estimated lifetime prevalence of eating disorder, anorexia nervosa and bulimia nervosa was 1% (95% CI, 1 - 2%), 1% (95% CI, 0 - 1%), 1% (95% CI, 0 - 1%) respectively.
Conclusion: The prevalence of eating disorders and its subcategories in Iran is much lower than high-income and developed countries. The available data are not sufficient to determine the exact prevalence of this disorder in the general population, especially in Iranian men.
