How Many People Suffer from Alcoholism in Brazil and Around the World?

Alcohol Use Disorder (AUD), commonly known as alcoholism, is one of the most prevalent mental health conditions worldwide. However, its true extent is difficult to predict, as many cases remain undiagnosed (1) due to limited access to specialized healthcare services in various countries.

Global Alcohol Consumption and Health Impacts

Alcohol Use Disorder (AUD) is characterized by a problematic pattern of alcohol consumption, leading to significant distress or impairment in various areas of life, such as work, relationships, and physical health. In 2019, it was estimated that around 400 million people aged 15 years and older were living with alcohol use disorders, with 209 million (52.3%) diagnosed with dependence. Globally, the prevalence of AUD was 5.1%, with a marked gender difference: 8.6% of men and 1.7% of women were affected in 2016 (2).

The prevalence of AUD tends to be higher in high-income countries (8.4%) and upper-middle-income countries (5.4%), suggesting the influence of socioeconomic factors on consumption patterns and alcohol availability. In contrast, low-income countries generally have lower prevalence rates, but may suffer from limited access to treatment and a higher prevalence of alcohol-related deaths.

The Situation in Brazil

Alcohol Use Disorder (AUD) also affects a significant portion of the Brazilian population. According to data from the Institute for Health Metrics and Evaluation (IHME) Global Burden of Disease (2024), presented on the platform Our World in Data (3), approximately 3.3% of the Brazilian population had alcohol use disorder in the 2010s. However, this rate has slightly decreased over recent decades, standing at about 2.9% in 2021. This reduction may reflect changes in access to information, public policies, and consumption patterns, although the prevalence remains high compared to other mental health disorders.

As with the prevalence of AUD, alcohol-attributable deaths in Brazil have also shown a trend of reduction over the last decade. According to the CISA publication Álcool e Saúde dos Brasileiros - Panorama 2024, the alcohol-attributable death rate fell from 36.7 to 30.4 per 100,000 inhabitants between 2010 and 2019. However, this trend was interrupted by the COVID-19 pandemic, with a significant increase starting in 2020, reaching 32.5 per 100,000 inhabitants in 2022. These data emphasize the importance of sustainable and continuous public policies to address the impacts of alcohol on public health.

Facing the Problem: Challenges and Opportunities

Despite the existence of effective treatments, such as cognitive-behavioral therapies and medications, access to these interventions remains limited. In Brazil and other countries, addressing alcohol use disorder requires:

• Reducing stigma: Awareness campaigns can help promote a more informed and compassionate view of the disorder.
• Improving screening: The use of simple tools in primary healthcare units can facilitate early diagnosis.
• Investing in accessible treatments: Expanding specialized services and including innovative therapies is essential.

Alcohol Use Disorder is a public health issue with profound implications for individuals, families, and societies. Understanding its prevalence and associated factors is crucial for developing effective prevention and treatment policies. By addressing stigma, improving screening, and expanding access to health care, it is possible to significantly reduce the impact of AUD on global health.

Remember, those suffering from this issue in Brazil can seek free help at any Basic Health Unit (health clinic) linked to the SUS (Unified Health System) or at units of the Psychosocial Care Centers for Alcohol and Drugs (CAPS-AD).
