An update on the epidemiology of eating disorders in Latin America: Current findings and future challenges

Abstract

Purpose of reviewWe systematically reviewed the recent literature on the epidemiology of eating disorders in Latin America.Recent findingsMost screened articles only investigated risk for eating disorders or disordered eating behaviors. Four studies reported prevalence for eating disorders. One study reported age-standardized prevalence ranging from 0.04% (95% CI [0.03, 0.06]) to 0.09 % (95% CI [0.07, 0.13] for anorexia nervosa and from 0.13% (95% CI [0.08, 0.17]) to 0.27% (95% CI [0.18, 0.37]) for bulimia nervosa. Three additional studies conducted in Brazil identified a general eating disorder point-prevalence of 0.40 % in children aged 6 to 14 years and a point-prevalence of 0.7 % (95 % CI [0.34, 1.55]) for bulimia nervosa, 1.4 % (95 % CI [0.81, 2.43]) for binge eating disorder and 6.2 % (95 % CI [3.10, 5.27]) for recurrent binge eating. SummarySince 2020, only few studies were published on the epidemiology of full-threshold eating disorders in Latin America. Prevalence was in a comparable range to previous findings. No studies regarding new DSM-5 eating disorder diagnoses were identified, and studies investigating the impact of the COVID-19 pandemic on prevalence or incidence of eating disorders in these countries are needed.
