One of the first steps in research or building a convincing public health argument is deciding what information or data you need to gather to make your case. Creating a quantifiable questions is a good place to begin. Here are some questions to ask yourself:
Here we see an example of a good research question about the impact of the Love Canal on the local populations cancer incidence.
They have a specific question about a specific incident. Did living in Love Canal increase the risk of cancer for residents? They then demonstrate how they are investigating the question, as well as how they would prove the hypothesis.
To make evidence based decisions you must first locate and understand the scientific evidence related to the topic.
To find scientific evidence about DDT or any other toxic substances the Agency for Toxic Substances and Disease Registry is a great first place to go. It is a branch of the CDC
Each substance has sets of resources aimed at the general community, as well as for Toxicological and Health Professionals. As Public Health professionals, you will want to start with the Toxicological Profile. This is an indepth examination of the given toxin.
The ToxGuide is a great quick 2-3 page summary of the evidence around the harmfulness of various chemicals.
The next step is to find and acquant yourself with data on Malaria. The WHO (World Health Orgnization) is a great first place to go. Check for Topics on their website, and you will find Malaria
Here you can find reports, as well as data about Malaria.
The Global Health Observatory (GHO) - The first resource you shoudl go to find health related data about your specific country. There is a wide variety of data available. You can find fact sheets on specific health concerns tailored to that country. Here is a sample from Guinea on the burden of Malaria. (click image for full size version)
