What is the meaning of the term "Causation" in epidemiology? Describe any 4 of Hill's criteria for determining causality?
The meaning of term causation in epidemiology is the cause which contributes to the production of another effect where cause and effect are partly depended on each other.
Brandford hill criteria consists of 9 principles.
They are strength, consistency, temporolity, specificity, plausibility, biological gradient, coherence, experimental evidence, analogy.
1)The strenght is most likely to be a causal.
2) Specificity is the outcome of a exposure which most likely be a causual.
3) Plausibility in which if it is biological then it is casual.
4)Consistency if observed in different groups of population then it would be casual.

Question 35 Which of Hill's Criteria of Causation is being described in the following scenario: Evidence has shown that Down's Syndrome occurs when there are three chromosomes on the 21st set and no other known exposure appears to be associated with the occurrence of Down's Syndrome Strength of the association Consistency of the association Specificity TemporalityThe role of chance may affect a statistical association because of: Loss to follow-up Selection bias Random variation Misclassification bias None of the answers listed
List three criteria for determining causality in epidemiology. Give examples for each.
Pick one of the four relationships below. Describe each aspects of Hill's criteria for causality applied to each disease relationship. This may take some research on your part to understand the relationship between the exposure and outcome. Some of these relationships may be casual, others may not. Say why it is or isn't. 1. HIV and AIDS 2. Pollution and Asthma attacks 3. UV exposure and skin cancer 4. Obesity and hearth diease
