University Body Composition Practical: Data Analysis & Ranking

This practical assignment delves into body composition analysis, evaluating the effectiveness of various anthropometric measurement techniques, including BMI, bio-impedance, and waist-to-hip ratio. The analysis highlights the limitations of relying solely on BMI and emphasizes the importance of comprehensive body composition assessments for both athletes and non-athletes. The assignment explores data display methods, such as tabulation and graphical representations, to facilitate comparison and understanding. Comparisons reveal discrepancies in results, underscoring the superior accuracy of body composition analysis in identifying underlying adiposity. The findings influence the ranking of methods, with body composition and bio-impedance analysis scoring higher, although cost and feasibility considerations are also addressed. The implications for healthcare professionals are discussed, emphasizing the need for a multi-method approach in patient assessments, while also considering cost and socioeconomic factors. References to similar comparisons in research are included, reinforcing the importance of comprehensive adiposity measurements and their correlation with cardiovascular disease risk.

Questions from ‘SCANNNED DOCUMENT’
Why is this?
Body composition analysis is often a more useful method for anthropometric
measurement, for athlete as well as non-athletes due to the incomplete and often incorrect
data presented by Body Mass Index (BMI) measurements. BMI highlights one’s distribution
of body weight as per their unique height and weight, but does not highlight the tissue
composition contributing to the weight. Hence, an individual, who has more lean muscle
mass than fat mass may be displayed as ‘overweight’ by BMI measurements whereas body
composition may highlight him/her as healthy, by providing a detailed measurement of the
tissue composition and body mass within physiological parameters (Gier et al., 2018).
How will you do this? How will you display the data?
In order to display the data, the body composition information from all individuals
may be tabulated based on separate columns highlighting the various methods of body
measurements used. Such data categorization and tabulation will allow for convenient and
simultaneous comparison between similar data obtained from various interventions. For
further ease in displaying, the data can be presented graphically in the form of charts like
graphs of pie diagrams since pictorial data presentation has been known to aid in easy data
analysis, understanding, comprehension and visual aesthetic (Hamilton, Ying & Leskovec,
2017).
What can you say from these comparisons?
From the provided data, the comparisons highlight the differences in results obtained
despite measuring the similar anthropometric measurements. It can observed that body
composition analysis using the Body Stat monitor provides a more comprehensive analysis
since it displays the true adiposity underlying the tissues of an individual. Hence, while other

2BODY COMPOSITION PRACTICAL
techniques such as BMI, bio-impedance and waist-to-hip ratio categorised most individuals
as ‘healthy’ or within the acceptable ranges, the body composition analysis highlight
abnormalities in adiposities. Hence, this suggests that we must use multiple methods for
anthropometric assessments instead of relying on just one for a more comprehensive analysis
(Fosbøl & Zerahn, 2015).
Does this affects how you would rank the different methods?
In terms of accuracy, the obtained results affect rankings resulting in body
composition and bio-impedance analysis methods to be ranked higher since they provide a
more comprehensive anthropometric data. However, such methods are expensive and may
not be feasible for all socio-economic groups hence making body weight and waist hip ratio
measurements easily applicable at the household level. Further, transportation of the Body
Stat equipment may not be feasible for analysis in remote areas due to tis requirements of a
laboratory setting (Ortega et al., 2016).
Are there any implications for healthcare? E.g.: Diagnosis? Selection of
Technique?
Such differences in results obtained signifies that health professionals must not rely
on merely a single method but use multiple methods for anthropometric analysis in patients.
However, prior to administration of the same, health professionals must also consider the cost
of each method and socioeconomic background of the patient since some methods are
expensive (Earthman, 2105).
Can you find any References for similar comparisons?
Similar comparisons were found in the research by Lam et al. (2015), where it was
examined that multiple measurement techniques of waist circumference, body mass index,
waist-to-hip ratio, waist-to-height ratio and body adiposity index are useful in the

measurement of adiposity and in the prediction of cardiovascular disease risk among
individuals.
