Stress Prevention and Stress Management Techniques IV01:26

Stress 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,...
Hypothesis Test for Test of Independence01:16

Hypothesis Test for Test of Independence

The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...
Cross-Sectional Research01:50

Cross-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...
Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
Substance Use Disorders Affecting Sleep01:24

Substance 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.
Understanding the concepts of physical dependence,...

Area of Science:

  • Public Health
  • Epidemiology
  • Addiction Research

Background:

  • Risky alcohol use is a significant public health concern among university populations globally.
  • Understanding trends and correlates of alcohol consumption is crucial for targeted interventions.
  • Previous studies in Brazil indicated concerning patterns, necessitating updated data.

Purpose of the Study:

  • To determine the prevalence and associated factors of risky alcohol use in Brazilian university students.
  • To compare these findings over a 12-year period (2006-2018).
  • To identify specific demographic and behavioral correlates of hazardous drinking.

Main Methods:

  • A cross-sectional survey utilizing a questionnaire administered to a representative sample of 6725 university students.
  • Assessment of alcohol use patterns using the Alcohol Use Disorders Identification Test (AUDIT).
  • Bivariate and multiple logistic regression analyses were employed to identify significant associations.

Main Results:

  • 34.5% of students reported risky alcohol use, associated with male gender, single status, higher socioeconomic status, and living with peers.
  • Risky drinking correlated significantly with academic difficulties, engagement in risky behaviors, and mental health issues.
  • A notable increase in risky drinking, high-risk drinking, probable alcohol use disorder, and intoxicated sexual intercourse was observed between 2006 and 2018, particularly among women.

Conclusions:

  • The study reveals persistently high and increasing rates of risky alcohol use among Brazilian university students, with a marked rise in female students.
  • These findings underscore the urgent need for comprehensive strategies combining individual support services with broad educational and awareness campaigns.
  • Addressing risky alcohol consumption requires a multi-faceted approach targeting individual behaviors and broader environmental factors within the university setting.
