What is the role of environmental factors in the development and maintenance of substance abuse and addiction?
-
Environmental factors have no influence on substance abuse and addiction.
-
Environmental factors can increase the risk of substance abuse and addiction, but they do not play a role in the maintenance of addiction.
-
Environmental factors can increase the risk of substance abuse and addiction, and they can also contribute to the maintenance of addiction.
-
Environmental factors can reduce the risk of substance abuse and addiction.
C
Correct answer
Explanation
Environmental factors, such as exposure to trauma, poverty, and lack of social support, can play a significant role in the development and maintenance of substance abuse and addiction. These factors can increase the risk of developing an addiction and make it more difficult for individuals to recover from addiction.

-
Increased risk of respiratory diseases
-
Increased risk of cardiovascular diseases
-
Improved mental health
-
Increased risk of cancer
C
Correct answer

What is the concept of confounding in epidemiology?
-
The distortion of the relationship between an exposure and an outcome due to the influence of a third factor
-
The presence of multiple risk factors for a disease
-
The occurrence of a disease in a population
-
The association between an exposure and an outcome
A
Correct answer
Explanation
Confounding occurs when the relationship between an exposure and an outcome is distorted due to the influence of a third factor, known as a confounder.
What are the potential risks and complications associated with immunosuppressive therapy in transplantation immunology?
-
Increased risk of infections
-
Increased risk of cancer
-
