Bulimia nerwowa – Epidemiologia

Bulimia nerwowa
Epidemiologia

Bulimia nervosa stanowi istotny problem zdrowia publicznego, szczególnie wśród młodych kobiet, z rozpowszechnieniem w populacji kobiet poniżej 30 roku życia wynoszącym od 0,8% do 2,4% w różnych krajach (USA 2,1%, Finlandia 2,4%, Australia 1,0%, Holandia 0,8%). Wskaźnik rocznej chorobowości wynosi około 0,43% (95% CI: 0,18-0,78), a wskaźnik chorobowości w ciągu życia 0,63% (95% CI: 0,33-1,02), z wyższą częstością u kobiet (stosunek 10:1 względem mężczyzn). Średni wiek zachorowania to 18 lat, z szczytem w okresie 15-25 lat. Bulimia występuje częściej w krajach rozwiniętych, w środowiskach miejskich oraz wśród osób wykonujących zawody lub uprawiających sporty wymagające kontroli masy ciała (np. zapaśnicy, kulturyści, gimnastycy). Wysoka jest współchorobowość z zaburzeniami psychicznymi (ok. 95%), w tym zaburzeniami lękowymi i nadużywaniem substancji (około 40%), a także podwyższone ryzyko prób samobójczych i śmiertelności (wskaźnik śmiertelności 1,74 na 1000 osobolat, standaryzowany wskaźnik śmiertelności 1-3%).

Epidemiologia bulimii nerwowej

Bulimia nerwowa stanowi istotny problem zdrowia publicznego, który dotyka przede wszystkim młode kobiety, choć występuje również wśród mężczyzn oraz w różnych grupach wiekowych i etnicznych. Epidemiologia tego zaburzenia jest złożona i zróżnicowana w zależności od regionu geograficznego, wieku badanej populacji oraz zastosowanych metod badawczych.¹²

Rozpowszechnienie bulimii na świecie

Ogólnie akceptowany wskaźnik punktowy rozpowszechnienia bulimii nerwowej w badaniach dwuetapowych wynosi około 1% wśród młodych kobiet.³ Badania epidemiologiczne wskazują jednak na szeroki zakres wyników: od 0,1% do 1,4% wśród mężczyzn oraz od 0,3% do 9,4% wśród kobiet.⁴ Według Gelder, Mayou i Geddes (2005), bulimia nerwowa występuje u 1-2% kobiet w wieku 15-40 lat.⁵

Rozpowszechnienie bulimii nerwowej w ciągu roku wynosi około 0,32% dla kobiet i 0,05% dla mężczyzn.⁶ Globalna metaanaliza wykazała, że ważony wskaźnik rocznej chorobowości wynosi 0,43% (95% CI, 0,18-0,78), natomiast wskaźnik chorobowości w ciągu życia dla bulimii nerwowej wynosi 0,63% (95% CI, 0,33-1,02).⁷ Inne badania sugerują jednak, że całkowita częstość występowania bulimii nerwowej w ciągu życia może być wyższa i sięgać 1,5% wśród kobiet i 0,5% wśród mężczyzn.⁸⁹

Warto zauważyć, że w ostatnich badaniach przeprowadzonych przez Silen i współpracowników w 2022 roku, które wykorzystywały różne metody diagnostyczne (SCID, MRFS, EDE, SSAGA i EDDI), oszacowano rozpowszechnienie bulimii nerwowej wśród kobiet poniżej 30 roku życia na poziomie 2,1% w USA, 2,4% w Finlandii, 1,0% w Australii i 0,8% w Holandii.¹⁰

Różnice geograficzne i kulturowe

Bulimia nerwowa występuje częściej w krajach rozwiniętych oraz w miastach – jedno z badań wykazało, że bulimia jest pięć razy częstsza w miastach niż na obszarach wiejskich.¹¹ Jest to choroba kosmopolityczna, opisywana we wszystkich grupach etnicznych, rasowych i społeczno-ekonomicznych.¹²

Interesujące są różnice międzykulturowe w rozpowszechnieniu bulimii nerwowej. Metaanaliza dotycząca Ameryki Łacińskiej wykazała średni wskaźnik punktowy rozpowszechnienia bulimii nerwowej na poziomie 1,16% w populacji ogólnej, co może sugerować, że rozpowszechnienie bulimii nerwowej jest wyższe w Ameryce Łacińskiej niż w krajach zachodnich.¹³ Jednym z możliwych wyjaśnień jest fakt, że jedzenie ma wysoką wartość emocjonalną w wielu kulturach latynoamerykańskich, co znajduje odzwierciedlenie w języku.¹⁴

Podobnie, ostatnie badania sugerują, że nastolatkowie pochodzenia afroamerykańskiego mogą być bardziej narażeni na rozwój bulimii nerwowej – jedno z badań wykazało, że nastoletnie dziewczęta afroamerykańskie są o 50% bardziej narażone na bulimię niż dziewczęta pochodzenia kaukaskiego.¹⁵ Wśród weteranów amerykańskich szacunki dotyczące bulimii nerwowej były wyższe wśród czarnoskórych weteranów w porównaniu do białych weteranów i innych osób kolorowych.¹⁶

Trendy czasowe i zapadalność

Niewiele badań przeprowadziło analizę zapadalności na bulimię nerwową. Według ogólnokrajowego badania podstawowej opieki zdrowotnej w Holandii, ogólny wskaźnik zapadalności na bulimię nerwową wykazywał tendencję spadkową z 8,6 na 100 000 osobolat w latach 1985-1989 do 6,1 na 100 000 osobolat w latach 1995-1999.¹⁷

Spadek występowania bulimii nerwowej w czasie potwierdzają również badania przeprowadzone wśród amerykańskich studentów uniwersytetów, w których punktowe rozpowszechnienie bulimii nerwowej wśród kobiet znacznie spadło z 4,2% w 1982 roku do 1,3% w 1992 roku i 1,7% w 2002 roku.¹⁸

Pomimo tych historycznych spadków, najnowsze dane wskazują na niepokojący wzrost zaburzeń odżywiania, w tym bulimii nerwowej, podczas pandemii COVID-19. W amerykańskiej armii roczne wskaźniki zapadalności na zaburzenia odżywiania wzrosły o około 79% między 2017 a 2021 rokiem, przy czym wskaźniki bulimii nerwowej wyraźnie wzrosły w okresie nadzoru. Chociaż wskaźniki zaburzeń odżywiania rosły od 2017 do 2019 roku, wyraźna zmiana wskaźników nastąpiła od 2020 do 2021 roku.¹⁹²⁰

Różnice demograficzne

Płeć

Bulimia nerwowa jest zdecydowanie częstsza wśród kobiet niż mężczyzn. Szacuje się, że stosunek kobiet do mężczyzn wynosi około 10:1.²¹ Rozpowszechnienie w ciągu życia bulimii nerwowej szacuje się na 2,59% wśród kobiet i 1,21% wśród mężczyzn.²² W Australii wskaźniki bulimii nerwowej są prawie dwukrotnie wyższe u kobiet w porównaniu do mężczyzn.²³

Według badania National Comorbidity Survey Replication w USA, rozpowszechnienie w ciągu życia było konsekwentnie 1-3 razy wyższe wśród kobiet niż mężczyzn dla bulimii nerwowej, podobnie jak w przypadku innych zaburzeń odżywiania.²⁴ Lekarze powinni jednak pamiętać, że mężczyźni również rozwijają bulimię nerwową i inne zaburzenia odżywiania, ale mężczyźni z bulimią często nie są diagnozowani lub leczeni przez długi czas.²⁵

Wiek

Średni wiek zachorowania na bulimię nerwową to 18 lat, podobnie jak w przypadku anoreksji nerwowej.²⁶²⁷ Szczytowy wiek zachorowania przypada na późną adolescencję i wczesną dorosłość (wiek 15-25 lat).²⁸²⁹ Bulimia nerwowa została również zgłoszona u osób starszych.³⁰

Kilka badań sugeruje, że wiek zachorowania na bulimię nerwową obniża się.³¹ Badania wykazały, że 75% osób ze zdiagnozowaną anoreksją nerwową i 83% osób ze zdiagnozowaną bulimią nerwową jest w wieku od 12 do 25 lat.³²

Grupy wysokiego ryzyka

Bulimia nerwowa występuje częściej wśród osób, których zawód lub hobby wymaga szybkiego przyrostu i/lub utraty wagi, takich jak zapaśnicy i kulturyści.³³ Sportowcy w niektórych dyscyplinach (np. biegacze i gimnastycy) są szczególnie podatni na zaburzenia odżywiania.³⁴

Wskaźniki zaburzeń odżywiania okazały się wyższe wśród sportowców w porównaniu z osobami nieprofesjonalnie uprawiającymi sport i wahają się od 6-45% wśród kobiet sportowców i 0-19% wśród mężczyzn sportowców.³⁵ Niedawne badanie wykazało, że w próbie sportowców wyczynowych ponad 86% spełniało kryteria zaburzeń odżywiania/zaburzeń odżywiania podprogowych.³⁶

Pewne zawody, takie jak aktorstwo, modeling i balet, również wydają się być związane z wyższym ryzykiem tych zaburzeń.³⁷ Ponadto, osoby z zespołem policystycznych jajników (PCOS) są bardziej narażone na wystąpienie co najmniej jednego zaburzenia odżywiania, w tym bulimii nerwowej.³⁸

Chorobowość i umieralność

Zaburzenia odżywiania, w tym bulimia nerwowa, mają wysoką współchorobowość z innymi zaburzeniami psychicznymi i somatycznymi.³⁹ Około 95% osób z bulimią nerwową ma inne zaburzenie psychiczne.⁴⁰

Prawie 40% osób z bulimią nerwową nadużywa substancji.⁴¹ Ponad połowa pacjentów z bulimią ma współistniejące zaburzenia lękowe.⁴² Badania wykazały, że około 31% osób z anoreksją nerwową, 23% osób z bulimią nerwową i 23% osób zdiagnozowanych z zaburzeniami odżywiania typu napadowego próbowało popełnić samobójstwo.⁴³

W niedawnej metaanalizie 12 badań opisujących wskaźniki śmiertelności pacjentów z bulimią nerwową stwierdzono ważony wskaźnik śmiertelności na poziomie 1,74 na 1000 osobolat (95% CI: 1,09-2,44), co oznacza, że rocznie umiera 0,17% pacjentów z bulimią nerwową.⁴⁴ Standaryzowane wskaźniki śmiertelności dla bulimii wynoszą od 1% do 3%.⁴⁵

Osoby z bulimią nerwową mają 7,5 razy większe prawdopodobieństwo próby samobójczej niż populacja ogólna⁴⁶ i są 7 razy bardziej narażone na śmierć w wyniku samobójstwa w porównaniu do grup dopasowanych pod względem płci i wieku.⁴⁷

Nadzór epidemiologiczny zaburzeń odżywiania

Nadzór epidemiologiczny zaburzeń odżywiania, w tym bulimii nerwowej, jest niezbędny do zrozumienia trendów i opracowania skutecznych programów profilaktycznych i interwencyjnych. Grupa Robocza ds. Nadzoru nad Zdrowiem Publicznym w Zakresie Zaburzeń Odżywiania to wielostanowa, interdyscyplinarna grupa badaczy i specjalistów zjednoczonych wspólnym celem rozwijania nadzoru nad zaburzeniami odżywiania w USA, ze szczególnym uwzględnieniem nadzoru poprzez ankietę Youth Risk Behavior Survey (YRBS) Centrów Kontroli i Zapobiegania Chorobom (CDC).⁴⁸

Przez wiele lat YRBS było jednym z niewielu źródeł danych krajowych na temat rozpowszechnienia zaburzeń odżywiania wśród młodzieży.⁴⁹ Latem 2024 roku CDC ogłosiło, że element oceniający objadanie się zostanie uwzględniony w Kwestionariuszu Krajowej Ankiety na temat Zachowań Ryzykownych Młodzieży (YRBS) na rok 2025, co oznacza pierwszy raz od ponad dekady, kiedy takie dane będą gromadzone.⁵⁰

Badacze podkreślają potrzebę ciągłego nadzoru nad zaburzeniami odżywiania w celu identyfikacji zmian w rozpowszechnieniu i charakterystyce istniejących i nowych pacjentów wymagających hospitalizacji.⁵¹ Jest to szczególnie ważne w świetle rosnących wskaźników hospitalizacji z powodu zaburzeń odżywiania wśród dzieci i młodzieży podczas pandemii.⁵²

Wyzwania w epidemiologii bulimii nerwowej

Badania epidemiologiczne dotyczące zaburzeń odżywiania, w tym bulimii nerwowej, napotykają na szereg wyzwań metodologicznych. Większość badań przeprowadzono na próbach wygodnych pacjentów szpitalnych, uczniów szkół średnich lub studentów uniwersytetów; badania nad bulimią nerwową wśród mniejszości etnicznych były również ograniczone.⁵³

Badania epidemiologiczne zaburzeń odżywiania często wykazują znaczne zróżnicowanie wskaźników rozpowszechnienia i zapadalności.⁵⁴ Prawdopodobne jest, że dane epidemiologiczne są często niedoszacowane, ponieważ wiele osób zmagających się z zaburzeniami odżywiania nie zgłasza się do placówek opieki zdrowotnej.⁵⁵

Badania wykazują, że większość osób z zaburzeniami odżywiania nie otrzymuje żadnego leczenia, albo dlatego, że nie są wykryte, albo dlatego, że odmawiają leczenia z powodu wstydu lub zaprzeczania swojej chorobie.⁵⁶ Niedawne badanie wykazało, że gdy pracownikom służby zdrowia psychicznego przedstawiono winietę opisującą zachowania i cechy pacjenta z zaburzeniami odżywiania, tylko jedna czwarta uczestników badania była w stanie prawidłowo zdiagnozować bulimię nerwową.⁵⁷

Ponadto, wyniki badania sugerują, że dostawcy mogą nie kojarzyć nadmiernego ćwiczenia z bulimią, mimo że jest ono wymienione w Diagnostycznym i Statystycznym Podręczniku Zaburzeń Psychicznych jako jedna z wielu strategii kompensacyjnych stosowanych przez osoby z bulimią.⁵⁸

Implikacje dla zdrowia publicznego

Bulimia nerwowa stanowi poważne wyzwanie dla zdrowia publicznego. Dane epidemiologiczne wskazują, że jest to zaburzenie stosunkowo powszechne, szczególnie wśród młodych kobiet, ale dotykające również mężczyzn oraz różnych grup wiekowych i etnicznych.⁵⁹⁶⁰

Implikacje dla zdrowia publicznego są znaczące, biorąc pod uwagę wysoką współchorobowość bulimii nerwowej z innymi zaburzeniami psychicznymi i somatycznymi, zwiększone ryzyko samobójstwa oraz podwyższone wskaźniki śmiertelności.⁶¹⁶²

Pandemia COVID-19 wywarła znaczący wpływ na rozpowszechnienie zaburzeń odżywiania, w tym bulimii nerwowej, podkreślając potrzebę zwiększonej czujności i gotowości systemów opieki zdrowotnej.⁶³⁶⁴

Biorąc pod uwagę, że zaburzenia odżywiania są trzecią najczęściej diagnozowaną chorobą przewlekłą wśród młodych kobiet⁶⁵ i że wiele przypadków pozostaje niewykrytych lub nieleczonych⁶⁶, istnieje pilna potrzeba poprawy świadomości, wczesnego wykrywania i dostępu do skutecznych metod leczenia dla osób z bulimią nerwową i innymi zaburzeniami odżywiania.

#1 Bulimia nervosa – Wikipedia
https://en.wikipedia.org/wiki/Bulimia_nervosa
There is little data on the percentage of people with bulimia in general populations. Most studies conducted thus far have been on convenience samples from hospital patients, high school or university students; research on bulimia nervosa among ethnic minorities has also been limited. Existing studies have yielded a wide range of results: between 0.1% and 1.4% of males, and between 0.3% and 9.4% of females. […] According to Gelder, Mayou and Geddes (2005) bulimia nervosa is prevalent between 1 and 2 percent of women aged 15-40 years. Bulimia nervosa occurs more frequently in developed countries and in cities, with one study finding that bulimia is five times more prevalent in cities than in rural areas. […] According to a study conducted in 2022 by Silen et al., which conglomerated statistics using various methods such as SCID, MRFS, EDE, SSAGA, and EDDI, the US, Finland, Australia, and the Netherlands had an estimated 2.1%, 2.4%, 1.0%, and 0.8% prevalence of bulimia nervosa among females under 30 years of age. This demonstrates the prevalence of bulimia nervosa in developed, Western, first-world countries, indicating an urgency in treating adolescent women. Additionally, these statistics may be misrepresentative of the true population affected with bulimia nervosa due to potential underreporting bias.
#2 Bulimia Nervosa: Practice Essentials, Background, Pathophysiology
https://emedicine.medscape.com/article/286485-overview
A literature review of the prevalence of eating disorders worldwide in young people suggests that bulimia nervosa (BN) has a lifetime prevalence of between 0.8% and 2.6% in women and between 0.1% and 0.2% in men. […] Most estimates of the prevalence of BN and other eating disorders come from Australia, Western Europe, and North America. However, smaller-scale epidemiological estimates suggest a similar prevalence of BN in many other regions and countries around the world, including Malaysia and Russia. […] Older estimates found lifetime prevalence estimates of BN (DSM-IV) to be 1.5% among women and 0.5% among men. Retrospective age-of-onset reports suggested that risk of BN increased with successive birth cohorts and that BN was significantly comorbid with many psychiatric disorders. […] BN was found to be more common among those whose occupation or hobbies require gaining and/or losing weight rapidly, such as wrestlers and competitive bodybuilders.
#3 Epidemiology of Eating Disorders: Incidence, Prevalence and Mortality Rates
https://pmc.ncbi.nlm.nih.gov/articles/PMC3409365/
Eating disorders are relatively rare among the general population. […] The occurrence of bulimia nervosa might have decreased since the early nineties of the last century. […] Only a few incidence studies of BN have been conducted. […] According to the nation-wide primary care study in the Netherlands, the overall incidence rate of BN tended to decrease from 8.6 per 100 000 person-years in 19851989 to 6.1 per 100 000 person-years in 19951999. […] Several studies suggest that age at onset of BN is decreasing. […] The generally accepted point prevalence of BN from two-stage studies is about 1 % among young females. […] The decrease in occurrence of BN over time found in the incidence studies is supported by a US study of university students in which the point prevalence of BN among women significantly decreased from 4.2 % in 1982, to 1.3 % in 1992 and 1.7 % in 2002. […] In a recent meta-analysis of 12 studies describing the mortality rates of patients with BN, a weighted mortality rate of 1.74 per 1000 person-years was found (95 % CI: 1.09-2.44), which means that per year 0.17 % of BN-patients die.

#6 Eating Disorder Statistics – National Eating Disorders Association
https://www.nationaleatingdisorders.org/statistics/
One-year prevalence of anorexia nervosa is 0.16% for females and 0.09% for males. […] A meta analysis found that atypical anorexia nervosa (AAN) occurs more frequently than anorexia nervosa in community samples, however fewer individuals with AAN are referred or admitted to special care for eating disorders. […] One-year prevalence of bulimia nervosa is 0.32% for females and 0.05% for males. […] One-year prevalence of binge eating disorder is 0.96% for females and 0.26% for males. […] In a nationally representative US-based study, up to 23% of individuals with BED had attempted suicide, and virtually all (94%) reported lifetime mental health symptoms: 70% mood disorders, 68% substance use disorders, 59% anxiety disorders, 49% borderline personality disorder, and 32% posttraumatic stress disorder.

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 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. […] The prevalence of eating disorders might be underestimated thus far. […] Eating disorders were especially common in Western countries and in females. […] The lifetime prevalence rates of eating disorders in females reached 2.58% (95% CI, 1.06-4.74) and 0.74% (95% CI, 0.24-1.52) in males. […] The lifetime and 12-month prevalence rates of EDs in Western countries were 1.89% and 0.68%, respectively, both over 8.5 times those in Asian countries (p<0.01).
#8 Eating disorder – Wikipedia
https://en.wikipedia.org/wiki/Eating_disorder
Bulimia affects females 9 times more often than males. Approximately one to three percent women develop bulimia in their lifetime. About 2% to 3% of women are currently affected in the United States. New cases occur in about 12 per 100,000 population per year. The standardized mortality ratios for bulimia is 1% to 3%.
#9 Classification and epidemiology of eating disorders in the DSM-5
https://psychiatry-psychopharmacology.com/en/classification-and-epidemiology-of-eating-disorders-in-the-dsm-5-132632
In May 2013 the Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has been published, which includes a substantially revised section on feeding and eating disorders. […] This DSM-5 chapter Feeding and Eating Disorders includes the following diagnoses: pica, rumination disorder, avoidant/restrictive food intake disorder, anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED). […] The lifetime prevalence of DSM-5 anorexia nervosa among women might be up to 4%, and of bulimia nervosa 2%. […] Community studies show that most people with eating disorders do not receive any treatment at all, either because they are not detected or because they refuse treatment due to shame or denial of their illness.

Athletes in certain sports (eg, runners and gymnasts) are particularly prone to eating disorders. […] The female athlete triad of eating disorders, hypothalamic amenorrhea, and osteoporosis is now well recognized and is particularly common in sports where slimness and body shape are of great importance, such as gymnastics, long-distance running, diving, and figure skating. […] However, the presence of the female athlete triad should suggest a diagnosis of anorexia, either typical or atypical. Eating disorders are also being recognized as a problem in predominantly male sports such as cycling, weight lifting, and wrestling. […] Certain vocations such as acting, modeling, and ballet dancing also appear to be associated with higher risk for these disorders. […] BN is a cosmopolitan disorder that has been described in all ethnic, racial, and socioeconomic groups.

Of 1583 records screened, 17 studies from Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela were included in the analysis. […] We found a mean point-prevalence rate of 0.1% for anorexia nervosa, 1.16% for bulimia nervosa, and 3.53% for binge-eating disorder (BED) in the general population. […] This meta-analysis indicates that the prevalence of anorexia nervosa seems to be lower, whereas the prevalence of bulimia nervosa and especially of BED seems to be higher in Latin America than in Western countries. […] Our findings show that eating disorders are common mental disorders in Latin America. […] However, some facets of Latin American culture might be protective for the development of anorexia nervosa and increase the risk for bulimia nervosa and BED. […] Further studies investigating the epidemiology of eating disorders and their relation to culture in Latin America are needed.

The point-prevalence of bulimia nervosa is mostly reported as 1% in two-stage studies of young females. […] In this meta-analysis, the heterogeneity of the studies was large. […] However, most of the studies found prevalence rates of at least the same range or higher than in Western Europe, but assessed eating disorders of both genders. […] This indicates that the general point-prevalence rate in Latin America is most likely underestimated in our study. […] We identified a higher BED point-prevalence in Latin America than previous studies in Western populations. […] A possible explanation might be that food has a high emotional value in many Latin American cultures which reflects in the language. […] Eating disorders are common in Latin America, with a lower prevalence rate for anorexia nervosa and a higher rate for bulimia nervosa and BED, when compared to Western Europe or the United States. […] These findings might reflect a stronger cultural bond of anorexia nervosa to a Western lifestyle than of bulimia nervosa and BED. […] However, we could not analyze cultural differences within Latin America as most of the studies included were conducted either in Brazil, Mexico, or Colombia.

Eating disorders are relatively rare among the general population. […] The occurrence of bulimia nervosa might have decreased since the early nineties of the last century. […] Only a few incidence studies of BN have been conducted. […] According to the nation-wide primary care study in the Netherlands, the overall incidence rate of BN tended to decrease from 8.6 per 100 000 person-years in 19851989 to 6.1 per 100 000 person-years in 19951999. […] Several studies suggest that age at onset of BN is decreasing. […] The generally accepted point prevalence of BN from two-stage studies is about 1 % among young females. […] The decrease in occurrence of BN over time found in the incidence studies is supported by a US study of university students in which the point prevalence of BN among women significantly decreased from 4.2 % in 1982, to 1.3 % in 1992 and 1.7 % in 2002. […] In a recent meta-analysis of 12 studies describing the mortality rates of patients with BN, a weighted mortality rate of 1.74 per 1000 person-years was found (95 % CI: 1.09-2.44), which means that per year 0.17 % of BN-patients die.

During this study’s 5-year surveillance period, from 2017 through 2021, annual incidence rates of eating disorders increased from 2.8 cases per 10,000 person-years (p-yrs) to 5.0 cases per 10,000 p-yrs. Periodic Health Assessment (PHA) forms completed in the 1-year period before and 1-year period after eating disorder diagnosis indicated increased prevalence of major life stressors, depression, and post-traumatic stress disorder (PTSD) following diagnosis. […] Increased incidence of eating disorders suggests need for promoting prevention and treatment among service members to improve medical readiness. PHA forms may provide greater insight into service members physical and mental well-being before and after eating disorder diagnoses. […] In this study, annual incidence rates of total eating disorders increased by approximately 79% between 2017 and 2021, with OUED accounting for the highest rates in military personnel when analyzed by type of eating disorder. Rates of BN and BED also notably increased throughout the surveillance period. Although rates of AN remained relatively stable in this study, it increased in 2021 among female service members.

[…] The peak age of onset for bulimia nervosa is in late adolescence to young adulthood (age 15 to 25 years). Studies suggest that 4 in 100 females are thought to suffer from bulimia nervosa at some point in their lives. Females are about 4 times as likely to be diagnosed with bulimia nervosa compared to males. Transgender adolescents and young adults are thought to be at higher risk of developing an eating disorder and further studies are needed to quantify this increased risk.

[…] Eating disorders, along with substance use disorders, have the highest mortality rate of all psychiatric disorders (Chesney, Goodwin Fazel, 2014). […] The mortality rate of those with Anorexia Nervosa is higher than other eating disorders (Fichter Quadflieg, 2016). […] The rate of mortality of individuals with Bulimia Nervosa and Binge Eating Disorder is lower than those with Anorexia Nervosa, but still significantly higher than the general population (NEDC, 2017). […] People with Anorexia Nervosa are more than 31 times more likely to attempt suicide and those with Bulimia Nervosa 7.5 times more likely to attempt suicide than the general population (Preti et.al, 2011). […] People with Anorexia Nervosa are 18 times more likely to die by suicide and those with Bulimia Nervosa are 7 times more likely to die by suicide relative to gender and aged matched comparison groups (Smith, Zuromski Dodd, 2018).

Ongoing surveillance of EDs is needed to identify changes in the prevalence and characteristics of existing and new patients requiring hospitalization. […] The objective of this study was to examine rates of ED hospitalizations among children and youth in Canada by age, sex, year, geography, length of stay, discharge disposition and ED diagnosis from 2010 to 2022. […] In Canada between 2010/11 and 2022/23 there were 18,740 ED hospitalizations among children and youth, with 64.9% being first-time hospitalizations. […] The rates of total and first-time ED hospitalizations significantly increased during the study period, with the highest rates reported in 2021. […] Higher rates of EDs among females is well documented in the literature, however, there are still a considerable number of males with EDs.

Between 2010/11 and 2022/23, 18,740 children and youth were hospitalized for an ED, 65.9% of which were first-time hospitalizations. […] The most frequent diagnosis was anorexia nervosa (51.3%). […] Females had significantly higher rates of ED hospitalization compared to males (66.7/100,000 vs. 5.9/100,000). […] Youth had significantly higher rates compared to children. […] Rates of pediatric ED hospitalizations in Canada increased significantly during the pandemic, suggesting that there may have been limited access to alternative care for EDs or that ED cases became more severe and required hospitalization. […] This emphasizes the need for continued surveillance to monitor how rates of ED hospitalizations evolve post-pandemic. […] Recent research has shown that the COVID-19 pandemic has contributed to an increase in ED hospitalizations among children and youth.
#53 Bulimia nervosa – Wikipedia
https://en.wikipedia.org/wiki/Bulimia_nervosa
There is little data on the percentage of people with bulimia in general populations. Most studies conducted thus far have been on convenience samples from hospital patients, high school or university students; research on bulimia nervosa among ethnic minorities has also been limited. Existing studies have yielded a wide range of results: between 0.1% and 1.4% of males, and between 0.3% and 9.4% of females. […] According to Gelder, Mayou and Geddes (2005) bulimia nervosa is prevalent between 1 and 2 percent of women aged 15-40 years. Bulimia nervosa occurs more frequently in developed countries and in cities, with one study finding that bulimia is five times more prevalent in cities than in rural areas. […] According to a study conducted in 2022 by Silen et al., which conglomerated statistics using various methods such as SCID, MRFS, EDE, SSAGA, and EDDI, the US, Finland, Australia, and the Netherlands had an estimated 2.1%, 2.4%, 1.0%, and 0.8% prevalence of bulimia nervosa among females under 30 years of age. This demonstrates the prevalence of bulimia nervosa in developed, Western, first-world countries, indicating an urgency in treating adolescent women. Additionally, these statistics may be misrepresentative of the true population affected with bulimia nervosa due to potential underreporting bias.

Epidemiological studies on eating disorders often show significant variation in prevalence and incidence rates. […] It is likely that epidemiological data is often underestimated, as many individuals struggling with an eating disorder do not present to health services. […] The peak age of onset for bulimia nervosa is in late adolescence to young adulthood (age 15 to 25 years). Studies suggest that 4 in 100 females are thought to suffer from bulimia nervosa at some point in their lives. Females are about 4 times as likely to be diagnosed with bulimia nervosa compared to males. Transgender adolescents and young adults are thought to be at higher risk of developing an eating disorder and further studies are needed to quantify this increased risk. […] The National Eating Disorders Association has some excellent information on statistics and epidemiology around eating disorders such as Bulimia.

In May 2013 the Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has been published, which includes a substantially revised section on feeding and eating disorders. […] This DSM-5 chapter Feeding and Eating Disorders includes the following diagnoses: pica, rumination disorder, avoidant/restrictive food intake disorder, anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED). […] The lifetime prevalence of DSM-5 anorexia nervosa among women might be up to 4%, and of bulimia nervosa 2%. […] Community studies show that most people with eating disorders do not receive any treatment at all, either because they are not detected or because they refuse treatment due to shame or denial of their illness.

When presented with a vignette describing the behaviors and characteristics of a patient with disordered eating, only a quarter of mental health providers who participated in a new study were able to correctly diagnose bulimia nervosa. […] The study findings also suggest that providers may not associate excessive exercise with bulimia, despite the fact that it is listed in the Diagnostic and Statistical Manual of Mental Disorders as one of multiple compensatory strategies used by people with bulimia. […] I think my biggest takeaway is that excessive exercise may not be on mental health providers radar and may be overlooked when patients are presenting for care, Leget said.

The surveillance period includes the COVID-19 pandemic, during which this study documented a temporal increase of eating disorder diagnoses among military personnel. While incidence rates of eating disorders were rising from 2017 to 2019, a marked shift in rates occurred from 2020 to 2021. These results are similar to findings among civilian populations demonstrating increased incidence of eating disorders during the COVID-19 pandemic, as aspects of pandemic life exacerbated eating disorder behaviors, due to multiple factors.
