Prevalence of Generalized Anxiety Disorder (GAD)
GAD Prevalence Among Health Care Workers During COVID-19
The COVID-19 pandemic has significantly impacted the mental health of health care workers, with a notable prevalence of Generalized Anxiety Disorder (GAD). A systematic review and meta-analysis revealed that the overall prevalence of GAD among health care workers was approximately 30.5% during the pandemic . This high prevalence underscores the urgent need for mental health support and preventive strategies for health care professionals.
Subthreshold GAD: A Hidden Burden
Subthreshold GAD, which includes symptoms that do not meet the full diagnostic criteria, is also prevalent and impactful. Studies indicate that the prevalence of subthreshold GAD is twice that of the full syndrome, affecting a significant portion of the population. This condition leads to considerable impairment in psychosocial and work functioning, and increases the risk of developing other mental health disorders .
GAD in Europe: Epidemiological Insights
In Europe, GAD affects about 2% of the adult population annually. It is one of the most frequent mental disorders encountered in primary care, with prevalence rates reaching up to 10% in this setting. Despite its high prevalence, GAD often goes unrecognized in general practice, highlighting a gap in mental health care .
GAD Among Children and Adolescents
GAD is also prevalent among younger populations. In a study conducted in Iran, the lifetime prevalence of GAD among children and adolescents was found to be 2.6%. Key predictors of GAD in this demographic include age, sex, maternal psychiatric history, and educational level. Comorbidity with other psychiatric disorders is common, with anxiety disorders being the most frequent .
GAD in Infertile Patients
Among infertile patients, the prevalence of GAD is notably high. A study in Tehran, Iran, reported a GAD prevalence of 28.3% in this group. Factors such as female sex, low educational level, prolonged infertility, and treatment failure were significantly associated with higher GAD prevalence .
Global Prevalence and Socioeconomic Factors
Globally, the prevalence of GAD varies significantly. Data from the World Health Organization's World Mental Health Survey Initiative indicate that the lifetime prevalence of GAD is 3.7%, with higher rates in high-income countries (5.0%) compared to middle-income (2.8%) and low-income countries (1.6%). GAD is often comorbid with mood and other anxiety disorders, and it leads to severe role impairment, particularly in high-income countries .
Conclusion
Generalized Anxiety Disorder is a prevalent and disabling condition affecting diverse populations worldwide. The high prevalence rates among health care workers, children, adolescents, and infertile patients highlight the need for targeted mental health interventions. Additionally, the significant burden of subthreshold GAD and its impact on daily functioning call for increased clinical attention and research. Addressing GAD effectively requires a comprehensive approach that includes early detection, appropriate treatment, and ongoing support across various settings.
