Introduction
Obesity is a weight related condition that is described as BMI value exceeding 30. It is caused by physical activity and dietary changes linked with societal and environmental factors that act in concert with inadequate supportive education, distribution, marketing, environmental, food processing, transport, urban planning, agriculture, and health policies. Perhaps the most significant aspect of obesity is that it is a health risk factor that predisposes individuals to non-communicable chronic ailments such as stroke and apnea (Ogden et al., 2014; Skinner & Skelton, 2014; Swift et al., 2014). Based on this awareness, there is a need to adopt a preventive strategy when addressing obesity, with the focus being on children since they are at a young age when the condition is easily managed.
A comparison of research questions
The eight research articles answered a range of questions in a bid to improve awareness of the nature of obesity. Cochrane et al. (2017) asked two questions. The first question is: Can a MCMD approach be operationalized for obesity management? The second question is: Is it possible to develop a theoretical approach to guide the operationalization? A literature review analyzes on Obesity based on PICOT Statement Paper and Literature Evaluation Table. Foster et al. (2017) asked the question: Do family-centered strategies exist that can be implemented by clinicians providing care for children and adolescents with obesity? Carayol et al. (2017) asked the question: How can proteome analysis provide new insights into the molecular mechanisms of complex traits like obesity? Martin et al. (2018) asked the question: Can healthy weight intervention improve thinking skills and school performance in children and teenagers with obesity? Torti et al. (2017) asked the question: Can lifestyle intervention improve school achievement, cognition and/or future success in children and adolescents with obesity or overweight? Ogden et al. (2014) asked two questions. The first question is: What is the national of childhood obesity? The second question is: What are the childhood obesity trends between 2003 and 2012? Swift et al. (2014) asked the question: What are the roles of Physical Activity (PA) and Exercise Training (ET) in the prevention of weight gain, initial weight loss, weight maintenance, and the obesity paradox? Skinner and Skelton (2014) asked two questions. The first question is: What is the prevalence of obesity and severe obesity over time for 14 years of the continuous National Health and Nutrition Examination Survey, 1999 to 2012? The second question is: Are there differences in differences in the obesity trends by age, race/ethnicity, and sex? The research questions from the eight selected journal articles are all concerned with obesity management, with the focus being on its occurrence among children. There relevance to the current research is highlighted by the fact that they all address the same topic (obesity) for the same population (children).
A comparison of sample populations
Cochrane et al. (2017) applied a qualitative research approach that recruited patients, researchers, educators, and practitioners who were identified as stakeholders. Although the exact number of participants is not mentioned, the research concedes that a large volume of data was generated from interviews and observations. Foster et al. (2017) applied a mixed methodology approach that included elements of both qualitative and quantitative research in which children and adolescents with diabetes were recruited as the study participants. Carayol et al. (2017) applied a quantitative approach in which932 Caucasian overweight or obese subjects were recruited in clinical centers from eight European countries A literature review analyzes on Obesity based on PICOT Statement Paper and Literature Evaluation Table. Martin et al. (2018) applied a literature review approached in which 18 studies applying evidence-based randomized and quasi-randomized controlled trials on children and adolescents with obesity or overweight were evaluated. Torti et al. (2017) applied a qualitative research approach that employed semi-structured interviews and thematic analysis on 28 patients from a cohort of 255 patients living with obesity and receiving care to support their weight management. Ogden et al. (2014) relied on data from National Health and Nutrition Examination Survey for 2011-2012 in which 9120 participants were recruited. Swift et al. (2014) relied on evidence-based qualitative review on weight loss from different modalities of exercise training and physical activities. Skinner and Skelton (2014) evaluated evidence-based qualitative case studies that had recruited 26,690 US children aged 2 to 19 years from 1999 to 2012. The present study will make use of these aspects by focusing on recruiting the participan
