Summary
Binge drinking is prevalent among Brazilian graduate students, affecting over half of those surveyed. Factors like male gender, certain academic fields, and mental health issues increase risk, while older age offers protection.
Area of Science:
- Public Health
- Psychology
- Sociology
Background:
- Binge drinking poses significant health and social risks.
- Graduate students are an understudied population regarding binge drinking behaviors.
- This study addresses binge drinking factors in Brazilian graduate students.
Purpose of the Study:
- Identify factors associated with binge drinking among Brazilian graduate students.
- Investigate the prevalence of binge drinking in this demographic.
- Explore the relationship between binge drinking and mental health.
Main Methods:
- Cross-sectional survey conducted from May to July 2022.
- Electronic questionnaire assessing binge drinking (AUDIT), sociodemographics, academics, and health.
- 4,062 Brazilian graduate students participated; analyses included bivariate and logistic regression.
Main Results:
- Prevalence of binge drinking was 57.3%.
- Common mental disorders (SRQ-20) were present in 33% of participants.
- Risk factors: male gender, 'other' sexual orientation, non-evangelical/no religion, engineering/agricultural/humanities fields, remote learning dissatisfaction, smoking, and positive mental disorder screening. Older age was protective.
Conclusions:
- High prevalence of binge drinking necessitates targeted interventions.
- Mental health promotion is crucial alongside binge drinking prevention strategies.
- Findings inform public health policies for graduate student well-being.

01:50Cross-Sectional Research
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
01:23Binge Eating Disorders
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
01:26Stress Prevention and Stress Management Techniques IV
Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...
01:27CNS Depressants: Alcohol and Nicotine
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

01:24Substance Use Disorders Affecting Sleep
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
