Uogólnione zaburzenie lękowe
Epidemiologia

Zaburzenie lękowe uogólnione (GAD) charakteryzuje się przewlekłym, trudnym do kontrolowania lękiem i martwieniem trwającym co najmniej sześć miesięcy, z towarzyszącymi objawami somatycznymi, takimi jak zmęczenie i napięcie mięśniowe. Globalne rozpowszechnienie GAD według WHO wynosi 3,7% (całożyciowo) oraz 1,8% (12-miesięcznie), z wyraźnymi różnicami regionalnymi – najwyższe w krajach o wysokim dochodzie (5,0%), a najniższe w krajach o niskim dochodzie (1,6%). W USA 12-miesięczna częstość występowania wynosi około 2,7%, a całożyciowa 5,7%. Kobiety są 2-3 razy bardziej narażone na GAD niż mężczyźni (3,4% vs 1,9% rocznie). GAD często współwystępuje z innymi zaburzeniami psychicznymi, zwłaszcza zaburzeniami nastroju i lękowymi, co komplikuje przebieg i leczenie. Mediana wieku zachorowania to około 31 lat, ale zaburzenie może pojawić się w każdym wieku, w tym u osób starszych i dzieci (częstość 5,7-12,8%).

Epidemiologia zaburzenia lękowego uogólnionego (GAD)

Zaburzenie lękowe uogólnione (Generalised Anxiety Disorder, GAD) stanowi jedno z najczęstszych zaburzeń psychicznych, charakteryzujące się nadmiernym i uporczywym martwieniem się, trudnym do kontrolowania, powodującym znaczny dyskomfort lub upośledzenie funkcjonowania, występującym przez większość dni przez co najmniej sześć miesięcy. Towarzyszą mu objawy psychologiczne, takie jak lęk i drażliwość, oraz objawy fizyczne (somatyczne), w tym zwiększone zmęczenie i napięcie mięśniowe.12

Rozpowszechnienie GAD na świecie

Globalne rozpowszechnienie zaburzenia lękowego uogólnionego jest znaczące, ale wykazuje istotne różnice między regionami i grupami demograficznymi. Według kompleksowych badań, około 4,05% światowej populacji cierpi na zaburzenia lękowe, co przekłada się na 301 milionów osób. Liczba osób dotkniętych zaburzeniami lękowymi wzrosła o ponad 55% w latach 1990-2019.3

Światowa Organizacja Zdrowia szacuje, że około 3,6% światowej populacji cierpi na zaburzenia lękowe, w tym GAD.4 Dokładniejsze dane pochodzące z badania WHO obejmującego ponad 147 000 dorosłych z 26 krajów wskazują, że całożyciowa częstość występowania GAD według kryteriów DSM-5 wynosi 3,7%, 12-miesięczna częstość występowania – 1,8%, a 30-dniowa częstość występowania – 0,8%.56

Rozpowszechnienie GAD różni się znacząco między krajami o różnym statusie ekonomicznym. Całożyciowa częstość występowania jest najwyższa w krajach o wysokim dochodzie (5,0%), niższa w krajach o średnim dochodzie (2,8%) i najniższa w krajach o niskim dochodzie (1,6%).7 Co ciekawe, mimo że GAD ma negatywny związek ze statusem społeczno-ekonomicznym w obrębie poszczególnych krajów, zaburzenie to jest szczególnie powszechne w krajach wysoko rozwiniętych.8

Rozpowszechnienie GAD w Stanach Zjednoczonych

W Stanach Zjednoczonych szacuje się, że w ciągu roku około 2,7% dorosłych cierpi na zaburzenie lękowe uogólnione.9 Natomiast całożyciowe rozpowszechnienie GAD w populacji USA wynosi około 5,7%.1011 Inne źródła podają zbliżone wartości, wskazując na 12-miesięczną częstość występowania GAD w USA na poziomie 2-3%, a całożyciową częstość występowania na poziomie około 5%.12

Według Krajowego Badania Współwystępowania (National Comorbidity Survey Replication, NCS-R) całożyciowe rozpowszechnienie GAD w USA może sięgać 5,7%, podczas gdy Stowarzyszenie Lęku i Depresji Ameryki podaje niższą wartość – 6,8 miliona dorosłych (3,1% populacji).13 W badaniu przeprowadzonym wśród starszych dorosłych w USA (w wieku 55 lat i starszych) oszacowano roczną częstość występowania GAD na 2,8%.14

Wśród nastolatków w USA szacuje się, że około 2,2% cierpi na GAD, a około 0,9% doświadcza poważnego upośledzenia funkcjonowania z tego powodu.15

Rozpowszechnienie GAD w innych krajach

Częstość występowania GAD różni się znacząco między krajami:

  • W Kanadzie całożyciowe rozpowszechnienie GAD oszacowano na 8,7%, a 12-miesięczną częstość występowania na 2,6%.16 W 2012 roku około 700 000 (2,5%) Kanadyjczyków w wieku 15 lat i starszych zgłosiło objawy odpowiadające GAD w ciągu poprzednich 12 miesięcy.17
  • W Republice Czeskiej całkowite rozpowszechnienie zaburzeń lękowych oszacowano na 8,3%, przy czym GAD było najczęstszym z nich, występującym u 3,6% populacji (3,0% u mężczyzn i 4,2% u kobiet).18
  • We Włoszech badanie epidemiologiczne wykazało relatywnie niższe całożyciowe rozpowszechnienie GAD na poziomie 2,3%, z większą częstością występowania u kobiet (3,6%) niż u mężczyzn (0,9%).19
  • W Indiach Krajowe Badanie Zdrowia Psychicznego z 2016 roku wykazało bieżącą ważoną częstość występowania GAD na poziomie 0,57%, co jest niższe niż globalne rozpowszechnienie.2021
  • W badaniu przeprowadzonym w Teheranie (Iran) stwierdzono, że 26% uczestników spełniało kryteria GAD, co jest wielokrotnie wyższe niż globalne rozpowszechnienie wynoszące 3,7%.22
  • W miejskich obszarach Chin rozpowszechnienie GAD szacuje się na 5,3%, przy czym tylko 0,5% osób zgłasza formalną diagnozę, co sugeruje znaczne niedodiagnozowanie tego zaburzenia.23

Czynniki demograficzne wpływające na występowanie GAD

Różnice płciowe

Zaburzenie lękowe uogólnione występuje znacznie częściej u kobiet niż u mężczyzn. Roczna częstość występowania GAD wśród dorosłych jest wyższa u kobiet (3,4%) niż u mężczyzn (1,9%).24 Podobnie, rozpowszechnienie GAD wśród nastolatków jest wyższe u dziewcząt (3,0%) niż u chłopców (1,5%).25

Badania konsekwentnie wskazują, że kobiety są 2-3 razy bardziej narażone na GAD niż mężczyźni.262728 We włoskim badaniu epidemiologicznym iloraz szans dla kobiet w porównaniu z mężczyznami wynosił 4,02 (95% CI: 1,96-8,26).29

Sugeruje się, że większe rozpowszechnienie GAD u kobiet może wynikać z czynników społeczno-ekonomicznych, takich jak większe prawdopodobieństwo życia w ubóstwie, częstsze doświadczanie dyskryminacji oraz częstsze doświadczanie przemocy seksualnej i fizycznej w porównaniu z mężczyznami.30

GAD może wystąpić w każdym wieku, ale najczęściej pojawia się po raz pierwszy w późnym okresie dojrzewania lub we wczesnej dorosłości. Mediana wieku zachorowania wynosi około 31 lat, a średni wiek zachorowania około 32,7 lat.3132

Mimo że GAD ma najwyższy średni wiek początku spośród wszystkich zaburzeń lękowych, może pojawić się lub nawrócić w dowolnym momencie życia. Co ważne, GAD jest również powszechnym zaburzeniem lękowym diagnozowanym u osób starszych.3334

W przypadku dzieci i młodzieży, ogólna częstość występowania GAD wynosi między 5,7% a 12,8%.35 W badaniu irańskim przeprowadzonym wśród dzieci i młodzieży w wieku 6-18 lat stwierdzono całożyciową częstość występowania GAD na poziomie 2,6%.36

Czynniki społeczno-ekonomiczne

GAD diagnozuje się częściej u osób, które są w separacji, rozwiedzione, bezrobotne, owdowiałe lub mają niski poziom wykształcenia, a także wśród osób o niskim statusie społeczno-ekonomicznym.37 W badaniu przeprowadzonym w Teheranie stwierdzono, że osoby z GAD częściej były stanu wolnego, niezadowolone z życia, o niskim statusie społeczno-ekonomicznym oraz zgłaszały niezdrowotny stan i niedawne czynniki stresogenne.38

Jednak w skali globalnej, rozpowszechnienie zaburzeń lękowych, w tym GAD, wydaje się wzrastać wraz z rozwojem społeczno-ekonomicznym, wyższym odsetkiem zależnej starszej populacji i urbanizacją.3940

Amerykanie pochodzenia afrykańskiego mają wyższe prawdopodobieństwo wystąpienia GAD, a zaburzenie to często manifestuje się u nich w różnych wzorcach.41

Współwystępowanie z innymi zaburzeniami

GAD często współwystępuje z innymi zaburzeniami psychicznymi. W badaniu włoskim stwierdzono, że aż 40% osób z GAD miało co najmniej jedno dodatkowe rozpoznanie zaburzeń nastroju, lękowych lub odżywiania.42

Badania wykazały, że GAD manifestuje wysoką współchorobowość z zaburzeniami nastroju i innymi zaburzeniami lękowymi, sięgającą 50% i więcej, w zależności od zaburzenia i próby badawczej. GAD często współwystępuje również z zaburzeniem afektywnym dwubiegunowym (BD) i może być związane z cięższym przebiegiem BD oraz zwiększonym ryzykiem samobójstwa.43

Według badań przeprowadzonych w USA, ponad 90% osób z GAD ma inną diagnozę psychiatryczną.44 W badaniu przeprowadzonym wśród starszych dorosłych w Szwecji stwierdzono wysoką współchorobowość GAD z depresją i innymi zaburzeniami psychicznymi.45

Stopień nasilenia i wpływ GAD

Stopień upośledzenia funkcjonowania spowodowany przez GAD waha się od łagodnego do poważnego. Wśród dorosłych z GAD w ciągu ostatniego roku, około 32,3% miało poważne upośledzenie, 44,6% umiarkowane upośledzenie, a 23,1% łagodne upośledzenie.46

W badaniu NCS-R w Stanach Zjednoczonych, 77% przypadków GAD zostało sklasyfikowanych jako umiarkowane lub ciężkie, przy czym upośledzenie funkcjonowania zawodowego lub życiowego było wymogiem dla obu tych klasyfikacji.47

Osoby z GAD w miejskich obszarach Chin doświadczają niższej jakości życia związanej ze zdrowiem, większego upośledzenia produktywności pracy i wyższego wykorzystania zasobów opieki zdrowotnej w porównaniu z osobami bez lęku.48

GAD może przyczyniać się do zachorowalności i śmiertelności poprzez mechanizmy neuroendokrynne i neuroimmunologiczne lub przez bezpośrednią stymulację nerwową (np. nadciśnienie lub arytmia serca). Przewlekły lęk może być związany ze zwiększonym ryzykiem zachorowalności i śmiertelności z przyczyn sercowo-naczyniowych.49

Luka terapeutyczna w GAD

Mimo istnienia skutecznych metod leczenia GAD, zaburzenie to jest często nierozpoznawane i nieleczone. Szacuje się, że tylko około 1 na 4 osoby potrzebujące (27,6%) otrzymuje jakiekolwiek leczenie.50

W badaniu indyjskim ogólna luka terapeutyczna dla bieżącego GAD wynosiła 75,7%.51 Natomiast w badaniu WHO stwierdzono, że leczenia poszukuje około połowa dotkniętych osób (49,2%), szczególnie osoby z poważnym upośledzeniem funkcjonowania (59,4%), współistniejącymi zaburzeniami (55,8%) oraz mieszkające w krajach o wysokim dochodzie (59%).52

Badania przesiewowe i nadzór epidemiologiczny

W badaniach przesiewowych w kierunku GAD powszechnie stosuje się narzędzia takie jak GAD-7 i GAD-2. GAD-7 to zwalidowane narzędzie samooceny, które zostało opracowane do przesiewu w kierunku GAD i oceny nasilenia jego objawów.53

Standardowy próg dla oceny zaburzenia lękowego uogólnionego wynosi 10 punktów w skali GAD-7, co odpowiada umiarkowanym i ciężkim objawom GAD i może sugerować obecność klinicznie istotnego stanu lękowego, który wymaga dalszej oceny, w tym wywiadu diagnostycznego i badania stanu psychicznego przez specjalistę zdrowia psychicznego.5455

Przy użyciu punktu odcięcia wynoszącego 8, GAD-7 ma czułość 92% i swoistość 76% dla diagnozy zaburzenia lękowego uogólnionego. Pomimo zaprojektowania jako narzędzie przesiewowe dla uogólnionego lęku, GAD-7 sprawdza się również dobrze jako narzędzie przesiewowe dla trzech innych powszechnych zaburzeń lękowych: zaburzenia panicznego, fobii społecznej i zespołu stresu pourazowego.56

Trendy i czynniki wpływające na rozpowszechnienie GAD

Rozpowszechnienie zaburzeń lękowych, w tym GAD, wzrosło w ciągu ostatnich trzech dekad. Wzrost ten może być związany z kilkoma czynnikami, w tym z rosnącą świadomością i lepszym rozpoznawaniem zaburzeń lękowych.5758

Badania sugerują, że etiologia GAD jest wieloczynnikowa, obejmująca czynniki psychologiczne, biologiczne, środowiskowe i genetyczne. Badania bliźniąt wykazały dziedziczność na poziomie około 32% dla GAD.5960

Pojawia się coraz więcej dowodów sugerujących, że pacjenci z GAD mogą doświadczać trwałej aktywacji obszarów mózgu związanych z aktywnością umysłową i myśleniem introspekcyjnym po bodźcach wywołujących zmartwienie.61

Tabela 1. Porównanie rozpowszechnienia GAD w różnych regionach i grupach demograficznych
Region/Grupa Całożyciowe rozpowszechnienie (%) 12-miesięczne rozpowszechnienie (%) Uwagi
Globalnie (średnia) 3,7 1,8 Według WHO, znaczne różnice między krajami
Kraje o wysokim dochodzie 5,0 – Najwyższe rozpowszechnienie mimo negatywnego związku z SES
Kraje o średnim dochodzie 2,8 – Pośrednie rozpowszechnienie
Kraje o niskim dochodzie 1,6 – Najniższe rozpowszechnienie
Stany Zjednoczone 5,7 2,7 Wyższe niż średnia globalna
Kanada 8,7 2,6 Jedne z najwyższych wskaźników
Włochy 2,3 – Niższe niż średnia globalna
Indie – 0,57 Znacznie niższe niż średnia globalna
Iran (Teheran) – 26 Znacznie wyższe niż średnia globalna
Mężczyźni (globalnie) – 1,9 Niższe rozpowszechnienie niż u kobiet
Kobiety (globalnie) – 3,4 2-3 razy wyższe rozpowszechnienie niż u mężczyzn
Nastolatki (USA) – 2,2 0,9% z poważnym upośledzeniem
Dzieci i młodzież (ogólnie) 5,7-12,8 – Znaczne rozpowszechnienie w młodszych grupach wiekowych

Podsumowanie

Zaburzenie lękowe uogólnione jest powszechnym zaburzeniem psychicznym o znaczącym wpływie na funkcjonowanie i jakość życia dotkniętych osób. Rozpowszechnienie GAD różni się znacząco między regionami geograficznymi i grupami demograficznymi, z wyższymi wskaźnikami występowania w krajach o wysokim dochodzie, wśród kobiet i osób o niskim statusie społeczno-ekonomicznym w obrębie poszczególnych krajów.

GAD często współwystępuje z innymi zaburzeniami psychicznymi, co zwiększa ogólne obciążenie chorobą i komplikuje leczenie. Mimo dostępności skutecznych metod leczenia, GAD pozostaje niedostatecznie rozpoznawane i leczone, szczególnie w krajach o niskim i średnim dochodzie.

Zrozumienie epidemiologii GAD ma kluczowe znaczenie dla opracowania skutecznych strategii profilaktyki, wczesnego wykrywania i leczenia tego zaburzenia. Badania epidemiologiczne dostarczają cennych informacji na temat rozpowszechnienia, czynników ryzyka i skutków GAD, co może pomóc w planowaniu zdrowotnym i opracowywaniu programów zdrowia psychicznego dostosowanych do potrzeb różnych populacji.

    Anxiety disorders comprise some of the most common mental health conditions. This study examined the global and regional burden of anxiety disorders over the last three decades. Epidemiological data relating to anxiety disorders from the latest Global Burden of Disease dataset were analyzed to determine the prevalence, incidence, and disability adjusted life years (DALYs) rates from 1990 to 2019 for 204 countries and regions. […] An estimated 4.05% of the global population has an anxiety disorder, translating to 301 million people. The number of persons affected has increased by more than 55% from 1990 to 2019. Anxiety disorder metrics show a continuous increase in prevalence, incidence, and DALY rates. […] The prevalence of anxiety disorders has been rising over the last three decades. The prevalence of anxiety appears to increase with socioeconomic development, a higher dependent older population, and urbanization.

    IMPORTANCE: Generalized anxiety disorder (GAD) is poorly understood compared with other anxiety disorders, and debates persist about the seriousness of this disorder. Few data exist on GAD outside a small number of affluent, industrialized nations. No population-based data exist on GAD as it is currently defined in DSM-5. […] OBJECTIVE: To provide the first epidemiologic data on DSM-5 GAD and explore cross-national differences in its prevalence, course, correlates, and impact. […] RESULTS: Respondents were 147261 adults aged 18 to 99 years. The surveys had a weighted mean response rate of 69.5%. Across surveys, DSM-5 GAD had a combined lifetime prevalence (SE) of 3.7% (0.1%), 12-month prevalence of 1.8% (0.1%), and 30-day prevalence of 0.8% (0). Prevalence estimates varied widely across countries, with lifetime prevalence highest in high-income countries (5.0% [0.1%]), lower in middle-income countries (2.8% [0.1%]), and lowest in low-income countries (1.6% [0.1%]). Generalized anxiety disorder typically begins in adulthood and persists over time, although onset is later and clinical course is more persistent in lower-income countries.

    Data from the World Health Organizations (WHO) Mental Health Survey collected general population surveys from 150 000 adults across 26 countries. Results indicate that GAD has a global lifetime prevalence of 3.7%, a 12-month prevalence of 1.8%, and a 30-day prevalence of 0.8%. […] Lifetime prevalence was highest among high-income countries and lowest among low-income countries. This is despite having a negative association between GAD and socioeconomic status within countries. GAD has an earlier average age of onset and is associated with more severe impairment across common life domains for people in higher income countries. Treatment is sought by approximately half of affected individuals (49.2%) especially those with severe role impairment (59.4%), comorbid disorders (55.8%), and those living in high-income countries (59%).

    CONCLUSIONS AND RELEVANCE: The findings of this study show that DSM-5 GAD is more prevalent than DSM-IV GAD and is associated with substantial role impairment. The disorder is especially common and impairing in high-income countries despite a negative association between GAD and socioeconomic status within countries. These results underscore the public health significance of GAD across the globe while uncovering cross-national differences in prevalence, course, and impairment that require further investigation.

    Prevalence rates within the United States vary widely, even when looking at reputable sources. On the low-end, the Anxiety and Depression Association of America reports that GAD effects 6.8 million adults (3.1% of the population), while the National Comorbidity Survey Replication (NCS-R) reports that GAD affects almost double that amount (5.7%). […] Under half of people with clinically significant GAD will seek treatment. GAD is twice as likely to occur in women than in men. GAD has the oldest average age of onset of all the anxiety disorders, typically beginning in a persons 30s. GAD is the most common anxiety disorder diagnosed in older adults. […] In the previously mentioned NCS-R study, 77% of GAD cases were classified as being moderate or severe, with impairment in occupation or role function being a requirement for both of these classifications. All classifications of GAD are associated with significant decreases in self-report measures of overall wellbeing and quality of life. However, a meta-analytic report found that while people with anxiety disorders had a significantly lower quality of life than non-clinical controls, specific anxiety disorders did not differ in terms of quality life. Individuals, no matter the anxiety disorder, who had higher levels of impairment and symptom severity, experienced the lowest quality of life.

    Generalized Anxiety Disorder (GAD) is a significant mental health issue worldwide, with varying prevalence rates across different regions. According to a comprehensive study by the World Health Organization, the lifetime prevalence of GAD is 3.7%, with a 12-month prevalence of 1.8% and a 30-day prevalence of 0.8%. The prevalence is notably higher in high-income countries (5.0%) compared to middle-income (2.8%) and low-income countries (1.6%). This disparity highlights the influence of socioeconomic factors on the occurrence of GAD. […] In older adults, the prevalence of GAD is also significant. A study using data from the National Epidemiologic Survey on Alcohol and Related Conditions found that the past-year prevalence of GAD in adults aged 55 and older was 2.8%. This study also noted that GAD in older adults is often comorbid with other psychiatric disorders, such as mood and anxiety disorders, and is associated with a reduced quality of life.

    Generalized anxiety disorder (GAD) is one of the most reported diagnoses in psychiatry, but there is some discrepancy between the cases identified in community studies and those identified in tertiary care. This study set out to evaluate whether the use of clinicians as interviewers may provide estimates in a community survey close to those observed in primary or specialized care. […] Overall, 55 (2.3%) subjects met the criteria for GAD, with greater prevalence in women (3.6%) than in men (0.9%): OR=4.02; 95%CI: 1.968.26. Up to 40% of those with GAD had at least another diagnosis of mood, anxiety, or eating disorders.

    Generalized anxiety disorder (GAD) is one of the common anxiety disorders leading to impairment and burden. However, GAD remains the least studied anxiety disorder. There is a need for nationally representative epidemiological data of GAD to understand the current burden and plan the mental health policies and programs to attain their unmet needs. Hence, this study focuses on epidemiology, socio-demographic correlates, disability, and treatment gap of GAD from India’s National Mental Health Survey (NMHS) 2016. […] The current weighted prevalence of GAD is 0.57%. The male gender and higher education groups have significantly lesser odds with current GAD. Urban metro and the married group have significantly higher odds with current GAD. […] NMHS 2016 has provided valuable insights into the epidemiology and burden of GAD among the general population.

[…] Anxiety disorders may contribute to morbidity and mortality through neuroendocrine and neuroimmune mechanisms or by direct neural stimulation (eg, hypertension or cardiac arrhythmia). Chronic anxiety may be associated with increased risk for cardiovascular morbidity and mortality. […] The presence of any anxiety disorder, phobias included, in combination with a mood disorder appears to increase likelihood of suicide attempts compared with a mood disorder alone.

    An estimated 4% of the global population currently experience an anxiety disorder (1). In 2019, 301 million people in the world had an anxiety disorder, making anxiety disorders the most common of all mental disorders (1). […] Although highly effective treatments for anxiety disorders exist, only about 1 in 4 people in need (27.6%) receive any treatment (2). […] Generalized anxiety disorder and panic disorder are included in the priority conditions covered by WHOs mhGAP Programme. This programme aims to help countries increase services for people with mental, neurological and substance use disorders through care provided by health workers who are not specialists in mental health.

    The 12-month prevalence of GAD across countries from the general population varies from 1.2-1.9% among European countries to 0.6% in Japan. Epidemiological studies specific to a particular country are very much required in anxiety disorders like GAD as prevalence rates differ from Western countries, and cultural variations exist. The epidemiology of GAD from a representative sample of India has been very scarce. […] The current weighted prevalence of GAD is 0.57% (95% CI 0.56-0.59). This figure is higher than the 12-month prevalence rates of GAD in Indian World Mental health Survey (WMHS) conducted in 2005, a decade earlier (0.34%).

    Data from the World Health Organizations (WHO) Mental Health Survey collected general population surveys from 150 000 adults across 26 countries. Results indicate that GAD has a global lifetime prevalence of 3.7%, a 12-month prevalence of 1.8%, and a 30-day prevalence of 0.8%. […] Lifetime prevalence was highest among high-income countries and lowest among low-income countries. This is despite having a negative association between GAD and socioeconomic status within countries. GAD has an earlier average age of onset and is associated with more severe impairment across common life domains for people in higher income countries. Treatment is sought by approximately half of affected individuals (49.2%) especially those with severe role impairment (59.4%), comorbid disorders (55.8%), and those living in high-income countries (59%).

    The GAD7 scale is a validated brief self-report measure which was developed to screen for GAD and assess the severity of its symptoms (2). A score of 10 or higher, corresponding to moderate and severe symptoms of GAD, may suggest the presence of a clinically significant anxiety condition that warrants further evaluation, including a diagnostic interview and mental status examination by a mental health professional (2,3). This report showed that 6.1% of adults scored 10 or higher on the GAD7 scale.

    The GAD-7 is the tool that the committee of experts recommends to evaluate generalized anxiety disorder in population-based surveys (Information sheet 1, Questionnaire 1). […] The standard threshold to assess generalized anxiety disorder is 10 (Spitzer et al., 2006), the threshold at which sensitivity and specificity are acceptable (Plummer et al., 2016; Spitzer et al., 2006). […] However, to conduct post-disaster surveillance, the long version with seven items is more appropriate since it makes it easier to assess changes over time, among other things because it evaluates their severity. […] The MINI evaluates 17 mental health problems, including generalized anxiety disorder. […] It also allows for a diagnosis when it is used in accordance with the administration criteria.

    The Generalized Anxiety Disorder 7-item (GAD-7) is a easy to perform initial screening tool for generalized anxiety disorder. […] When screening for anxiety disorders, a score of 8 or greater represents a reasonable cut-point for identifying probable cases of generalized anxiety disorder; further diagnostic assessment is warranted to determine the presence and type of anxiety disorder. Using a cut-off of 8 the GAD-7 has a sensitivity of 92% and specificity of 76% for diagnosis generalized anxiety disorder. […] Although designed as a screening tool for generalized anxiety, the GAD-7 is also performs reasonably well as a screening tool for three other common anxiety disorders: Panic Disorder, Social Anxiety Disorder, and Posttraumatic Stress Disorder. […] Performance of GAD-7 as Screening Tool for Anxiety Disorders (Using GAD-7 Score Cut-off of 10) Test Sensitivity Specificity Positive Likelihood Ratio Generalized Anxiety Disorder 89% 82% 5.1.

    Anxiety disorders comprise some of the most common mental health conditions. This study examined the global and regional burden of anxiety disorders over the last three decades. Epidemiological data relating to anxiety disorders from the latest Global Burden of Disease dataset were analyzed to determine the prevalence, incidence, and disability adjusted life years (DALYs) rates from 1990 to 2019 for 204 countries and regions. […] An estimated 4.05% of the global population has an anxiety disorder, translating to 301 million people. The number of persons affected has increased by more than 55% from 1990 to 2019. Anxiety disorder metrics show a continuous increase in prevalence, incidence, and DALY rates. […] The prevalence of anxiety disorders has been rising over the last three decades. The prevalence of anxiety appears to increase with socioeconomic development, a higher dependent older population, and urbanization.

    Disease epidemiology is critical for understanding population trends, such as whether or not anxiety is increasing, covariates associated with changing trends, and factors involved in the control and management of anxiety disorders. […] A comprehensive epidemiological study of the global burden of anxiety disorders, as well as their sociodemographic associations, is needed to evaluate population-wide trends and potential factors associated with anxiety, as well as to more efficiently target health promotion efforts to reduce the economic and social burden associated with this mental health issue. […] The global prevalence of anxiety continues to increase, along with the associated social and economic burdens of anxiety disorders. Higher rates of anxiety disorders were associated with more economic development, a higher dependent older population, and urbanization.

    Generalized anxiety disorder (GAD) and panic disorder (PD) are common mental health conditions in adults that are often seen in primary care. […] In the United States, lifetime prevalence is 8% and 5% for GAD and PD, respectively. […] Females are two to three times more likely to experience GAD and PD, although the gender discrepancy is less apparent later in life. […] The etiology of anxiety disorders is multifactorial. Psychological, biological, environmental, and genetic theories can help explain the cause of anxiety disorders. […] Studies of twin patients have found heritability of approximately 32% for GAD and 48% for PD. […] There is insufficient evidence to support universal screening for GAD or PD in adults at this time; however, the U.S. Preventive Services Task Force is updating guidelines regarding screening for anxiety, suicidality, and depression. […] The GAD-2 and GAD-7 are two-item and seven-item validated screening tools for GAD. […] The Patient Health Questionnaire for PD is the most accurate screening tool for PD in patients expressing sudden episodes of anxiety or fear.

    Twin studies suggest that environmental and genetic factors are likely involved. […] The etiology of PD is also not well understood. The neuroanatomical hypothesis suggests that a genetic-environment interaction is likely responsible. Patients with PD may exhibit irregularities in specific brain structures, altered neuronal processes, and dysfunctional corticolimbic interaction during emotional processing. […] Evidence suggests that GAD and PD usually occur with at least one other psychiatric disorder, such as mood, anxiety, or substance use disorders.

    Generalized anxiety disorder (GAD) and panic disorder (PD) are among the most common mental disorders in the United States, and they can negatively impact a patient’s quality of life and disrupt important activities of daily living. […] The 12-month prevalence for GAD and PD among U.S. adults 18 to 64 years of age is 2.9% and 3.1%, respectively. In this population, the lifetime prevalence is 7.7% in women and 4.6% in men for GAD, and is 7.0% in women and 3.3% in men for PD. […] The etiology of GAD is not well understood. There are several theoretical models, each with varying degrees of empirical support. An underlying theme to several models is the dysregulation of worry. Emerging evidence suggests that patients with GAD may experience persistent activation of areas of the brain associated with mental activity and introspective thinking following worry-inducing stimuli.
