Literature Search, Rapid Critical Appraisal, and Summarization

· Locate a minimum of 4 research articles related to the topic and PICOT questions that you developed (Do not use the article that was used before)


1. In children under the age of six years, do physical activities compared to healthy diet result to decrease in body weight within three months?

2. In obese children between the age of two to 19 years, how does collective family involvement in healthy lifestyle compare to isolating the children lifestyles leads to reduced obesity within a year?
