Remember that messy line? You might begin with a basic idea rather than a research question to first see what's out there! You may go through several iterations of keyword search strategies before you determine one and/or your research question.
Note: The more concepts you AND into a search, the results become smaller and more specific. You might want to begin a search with just two concepts.
Concept A:
- obes*
- overweight
- over-weight
Concept B:
- physical activity
- exercise
- fitness
Concept C:
- child*
- teen*
- adolescen*
- youth
