Behavioral Risk Factor Surveillance System (BRFSS) -- The CDC's "premier system of health-related telephone surveys that collect state data about U.S. residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services. [It] now collects data in all 50 states as well as the District of Columbia and three U.S. territories."
Incidence: "The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from Prevalence, which refers to all cases, new or old, in the population at a given time." [MeSH definition]
One of the best ways to get incidence/prevalence data is to look at journal articles in PubMed and EMBASE.
- Remember that the statistics tend to be in the first paragraph of the article, and *not* in the abstract
- In PubMed, you can choose among these MeSH headings about statistics to include in your searches
