PUBH 8035 Module 7 Discussion; Assessing Causality and Implications for Public Health Policy

For this week, the article I chose was about Dietary Glycemic Index (GI) and Glycemic Load (GL) and the risk of Type 2 Diabetes (T2D). The article concluded that the high confidence in causal associations for incident T2D is sufficient to consider inclusion of GI and GL in food and nutrient-based recommendations (Geoffrey et al., 2019).


·What is the epidemiological causal inference model used by the authors? Provide a detailed summary of how the authors used the model to assess the association.


·Do you agree with the author’s choice of causal model? Why or Why not? Provide evidence and justification to support your assessment.


·What are the implications for public health policy, given your interpretation of the evidence for causality presented in the article?


Epidemiology md 7 discussion

For this week, the article I chose was about Dietary Glycemic Index

(GI) and Glycemic Load (GL) and the risk of Type 2 Diabetes (T2D). The

article concluded that the high confidence in causal associations for incident

T2D is sufficient to consider inclusion of GI and GL in food and nutrientbased recommendations (Geoffrey et al., 2019).

What is the epidemiological causal inference model used by the authors?

Provide a detailed summary of how the authors used the model to assess the

association.

The epidemiological causal inference model used in this article was the

Bradford-Hill guidelines for causality. The authors used the model to assess

the association in the following criteria:

1. Strength of association: T2D-Gi and the T2D-GL risk relations were proved

to be sufficiently strong with an RR > 1.20, lower 95% CI. > 1.10 to

warrant action in favor of public health.
