When you have a geographic area in mind, and are not sure what public health topic to choose for your research project, use these:
Using either of the databases linked here, Academic Search Complete or Global Health, construct a beginning search following the patterns given in the examples below.
NOTE: Geography is difficult. You can try a city/state combination, but odds are against it working. You'll probably have to broaden the search geographically!
TOPIC: Childhood obesity among low-income communities in Alameda County
TOPIC: Asthma among school-age children in Richmond CA
TOPIC: Diabetes among Latinos in Los Angeles, CA
Run that initial search. Look closely at the relevant items retrieved, especially at the words/phrases labeled SUBJECTS. You are looking for relevant language describing each of the main ideas in your search.
Once you have found relevant language, edit your search so that you are searching in the SUBJECT field rather than the TITLE field.
In the examples above, our initial language was good for the 1st two examples. However, this is what the 3rd search ended up with. There was no consistent SUBJECT term for the idea of LATINO.
