ASSIGNMENT 21
Diet, physical activity and behavioural interventions for the treatment of
overweight or obese children from the age of 6 to 11 years.
As per the report of the Public Health Agency of Canada, the rate of obese children is
high, and there were 30 children between 5-17 years that can be considered as overweight or
obese (Bozkurt et al., 2018). The Body Mass Index (BMI) of an obese person is more than
30, where an overweight individual has a BMI range of 25-30. The aim of the paper is to
critically review an article, ‘Diet, physical activity and behavioral interventions for the
treatment of overweight or obese children from the age of 6 to 11 years’ in order to address
the issue of childhood obesity in the current context.
Rationale of the type of study design used
The purpose of the article is to assess the impact of diet, behavioral intervention, and
physical activity for treating wither overweight or obese children between the age of 6 to 11
years old (Mead et al., 2016). It was a systematic review that included study design used in
this particular review was 70 randomized controlled trials (RCTs) that included 8461
participants that include all the variables presented in the aim. From the perspective of
Snyder et al., (2016), it can be stated that the study design used in the research was
appropriate in nature as the observational study will not be able to determine the impact of
the variables on the target population. It specifically focused on understanding the effects of
diet, physical activity, and behavioral intervention upon the treatment process of the
participants. The study was conducted in thirty-one trials that involve reporting of adverse
events as well as a meta-analysis for assessing the impact on treatment and post-
interventional period. Therefore, it included a large number of studies that gave a wide range
of perceptions to testify to the outcome. The use of both qualitative and quantitative studies
has enhanced the context of the particular research enabling the audience to understand the

different impacts of each of the factors mentioned in the study (Cheng, Fu & de Vreede,
2017). However, the issue was found in the sample size, which was small as compared to the
global statistics of children suffering from obesity-related issues. There was a lack of a
controlled trial in the study that affected the reliability to a large extent.
Finding consistent with the knowledge and information
From the systematic review, it was found that the BMI z score was obtained; however, there
was no distinct outcome derived from the result. The impact of interventional strategies such
as improvement in the quality of life was found to unclear, and no report stated any adverse
events such as death, socioeconomic effect, or morbidity rate in the study. As per the study of
Guyatt (2016), when a research journal is unclear, it offers low-quality evidence that supports
the results. In this particular case, the overall quality of the evidence obtained from the
finding was not consistent in nature as a result; it implies that the evidence was of poor
quality and cannot be taken into considerations because of the study design incorporated. In
addition, it can be stated that the result was inconsistent with the information or knowledge
obtained from other studies because it did not specifically focus on the target population that
is children; therefore, the study was majorly presented on obesity rather than childhood
obesity. The strength found in this particular article is that the evidence is up-to-date as it was
in July 2016. It used a PICO format for establishing a well-built clinical question related to
the objective of the study (Scells et al., 2017). The article stated that evidence-based practice
was employed and helped in proposing a search strategy from MEDLINE, CENTRAL,
CINAHL, PsycINFO, government sites, LILACS, and ICTRP Search portal to access the
studies and reviews. It is important to note that the reported relationship in the article does
make sense from the findings. That is not a supported statement.
