Resources to Gather Background Information

The following resources will provide you some background information on obesity and it's causes. Doing background research will not only help you narrow your focus, but will also help you identify keywords to use when searching the databases for scholarly articles. 

Reference Databases

Trusted Websites

Boolean Operators 

Using Boolean operators in a database is highly recommended, as this approach usually generates the most useful results.  Databases are not "intuitive" like search engines (e.g., Google) - they must be "told" how to process a search query.  Boolean operators let you "tell" the database what you want to see in your results.  


Use AND to connect KEYWORDS - Retrieves sources with both/all terms [refines search]

Example: diabetes AND adult AND self-management 


Use OR to connect SYNONYMS & LIKE CONCEPTS - Retrieves sources with either/any term(s) [broadens search]

Example: heart attack AND (female OR women) AND symptoms


Use NOT to EXCLUDE word(s) - Eliminates sources with the word(s) following NOT 

Example: Omega-3 fatty acids NOT fish oils 

Identifying Keywords

When you are conducting your background research on your topic, consider the who, what, when, where and why of what you are reading, and highlight or write the main points down. You can use those as keywords in the databases!

Who, what, when, where and why

Use some of the databases listed below to locate scholarly resources on your topic.
