Summary
Internal migration in Nepal increases the risk of alcohol use and alcohol use disorders (AUD). This highlights the need for targeted support services for internal migrants to prevent problematic drinking behaviors.
Area of Science:
- Public Health
- Sociology
- Epidemiology
Background:
- Alcohol use is a significant global health issue, particularly in low- and middle-income countries (LMICs).
- LMICs face a growing burden of alcohol-attributable diseases despite lower per capita consumption.
- Internal migration in LMICs may exacerbate alcohol-related health risks due to increased stress and changing social environments.
Purpose of the Study:
- To investigate the association between internal migration and alcohol use.
- To examine the relationship between migration, opportunity to drink, and transition to regular alcohol use and alcohol use disorders (AUD).
- To assess these relationships in Nepal, a low-income South Asian country.
Main Methods:
- A representative sample of 7435 individuals aged 15-59 in Nepal was surveyed (2016-2018).
- Data collection included clinically validated measures of alcohol use and disorders, and life history calendars for migration experiences.
- Discrete-time hazard models were used to analyze associations between migration and alcohol use outcomes.
Main Results:
- Internal migration was linked to increased odds of opportunity to drink (OR 1.32), regular alcohol use (OR 1.29), and alcohol use disorders (AUD) (OR 1.24).
- The association between migration and opportunity to drink was significant for females.
- Associations between migration, regular use, and AUD were significant for males.
Conclusions:
- Internal migrants face elevated risks for transitioning to alcohol use and developing alcohol use disorders.
- Findings underscore the importance of addressing the specific needs of internal migrants.
- Support services for internal migrants are crucial for preventing problematic alcohol use in this population.

01:16Hypothesis Test for Test of Independence
3.6K
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)...

01:27CNS Depressants: Alcohol and Nicotine
274
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...

00:53Migration
8.0K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

8.7K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

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...

01:26Stress Prevention and Stress Management Techniques IV
49
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,...
