Are children (p) with obese parents (I) at an increased risk for obesity (O) compared with children (P) without obese parents (C) during the ages of 0 to 18 years (T)?
The databases I utilized were PubMed and Cochrane Library, which are among the recognized databases containing health research articles. I began the search in a comprehensive manner using the search term “obesity.” In both the databases, the results once I keyed in words obesity were many. In PubMed, there were 369,341 results, while in Cochrane Library, there were 137 reviews. To narrow down the results, I used the search term “childhood obesity, and in PubMed, there were 30,936 results, while in the Cochrane library, there were 18 reviews. To further narrow the results, it is advisable to use search terms that are specific for the PICOT question. This way, the results will be relevant to the study being carried out.
The use of keywords is the first step towards increasing the rigor and effectiveness of a database search. The vocabulary used should be appropriate and applicable to the PICOT question. This is because, if the vocabulary is not appropriate and applicable, the search results will not be relevant to the PICOT question. Combining the keyword and concepts using the Boolean operators will help to make the research effective. Providing a specific timeline will also help to narrow down the results to what is required. In research, some publications become obsolete over time since their results are invalid. Therefore, narrowing the search to a specific time period will help get results applicable to the research.
