Introduction
Obesity is defined as a medical illness where excess fat has accrued to the extent
that it has a negative effect on the human body of the consumer. It is a complex disorder
that includes an extreme amount of fat in the human body. Obesity is also defined as a
medical problem that enhances other health disorders, for example, diabetes, certain
cancers, cardiovascular disorder and many more. The major significance of this paper is to
analyze the impact of obesity on the human body and review the recent papers published
on the obesity health problem. There are major 5 journal articles that will be reviewed in
terms of significance, methodologies imposed major contribution and quality.
Critical review
A. Prevalence of Obesity and Severe Obesity in US Children, 1999–2016
This journal paper was written by Asheley and other researchers in the year 2018 and
highlighted the prevalence of the obesity health problem (Skinner, Ravanbakht, Skelton,
Perrin, M., & Armstrong, 2018).
Significance
This paper is about the prevalence of obesity in which the writer highlighted risk
factors related to the obesity disorder and reviewed the impact of obesity on children and
adolescents. The significance of this paper is to deliver efficient occurrence information on
obesity trends between United States children.
Methodology
This paper utilized the NHANES for 1999 to 2016 years and adopted a qualitative
methodology for obtaining reliable points in the case of obesity. The researchers reported
the occurrence approximations of obesity and overweight by 2-year NHANES cycles and
performed a comparison process using Wald tests.

Contribution to the topic
This paper plays a significant contribution to the research topic as it provided depth
information in the context of obesity health disorder. The investigation provided a way to
understand the effect of obesity on families in the United States. This paper helped to
address the risk factors related to the obesity health problem.
Quality
In terms of quality, this paper is more reliable and effective that helped to understand
the key aspects of the obesity health problem and addressed the research gaps produced in
recent papers. The researchers adopted appropriate methods while gathering and
analyzing the data and also included opinions of other researchers that enhanced research
quality.
B. Increased oxidative stress in obesity and its impact on metabolic syndrome
This journal paper was published by the Shigetada and other papers in the year 2017
and provided viewpoints about obesity and its impact on metabolic condition (Furukawa,
et al., 2017).
Significance
The key significance of this investigation is to review the key characteristics and risk
factors related to obesity health problems. The researchers provided a way to identify the
impacts of obesity disorder on metabolic syndrome and evaluated the oxidative pressure
and plasma adiponectin stages in obese patients.
Methodology
In which the researchers included both qualitative and quantitative designs for
obtaining reliable data and numerical facts in the case of obesity health problems. Plasma
and urinary sample was gathered from 140 subjects including 69 men and 71 women. All
creatures were bought from Clea Japan and contained in a room and data were analyzed
through statistical tools.
