LibGuides: Nutrition : Develop a Topic

Develop Your Topic

Before you develop your research topic or question, you'll need to do some background research first.

Some good places to find background information:

Your textbook or class readings
Encyclopedias and reference books
Credible websites
Library databases

Try the library databases below to explore your topic. When you're ready, move on to refining your topic.

Find Background Information:

Credo This link opens in a new window
Provides full-text online access to hundreds of multidisciplinary reference book collections, including art, history, law, medicine, psychology, technology, bilingual dictionaries and encyclopedias.

PICO:

P-Population

This is based off of the characteristics of a population, with examples of variables being age, race, and gender, with a set of specific condition or set of circumstances.

I-Intervention or Interest

This variable would be a treatment, diagnostic test, or therapy.

C-Comparison Group

This is the comparison treatment to the intervention selected. The comparison may be with another medication, another form of treatment such as exercise, or no treatment at all otherwise known as a control group.

O-Outcome

What would be the desired result, and what result is not desired? What is your goal with this research? Outcomes should be measurable.

Example:

P: Those at Risk for Cardiovascular Disease (Coronary Heart Disease)

I: Mediterranean Style Diet

C: Usual Care

O: Reduction of Coronary Heart Disease

Tips:

Start with the population, and the intervention in your search first.
A comparison is not always included in a PICO Analysis.
To see examples of PICO in action, check out Cochrane Reviews:

Cochrane Library
A collection of various evidence based medicine databases providing information on treatments and medical interventions to support effective decision making in practice.

Now that you've done some background research, and thought of your PICO question, you might need to troubleshoot your topic if you do not find any results.

The easiest way to do this is to change the variables in your PICO question.

Example:

P: 65+

I: Mediterranean Diet

C: Usual Care

O: Reduction of Coronary Heart Disease in Population

We can specify the outcome to a reduction in strokes, or could change or specify the population further.
