Body Composition Analysis

Abstract
The health risks (comorbidities) associated with obesity, such as type 2 diabetes, cardiovascular disease, high blood pressure and stroke has also increased. It is imperative that we regularly assess levels of overweight and obesity to inform health policies and intervention strategies. The use of valid and reliable assessment tools for overweight and obesity at community level is therefore of great importance. There are numerous methods available to assess body composition. However, there is no single universally recommended method for body composition assessment. Criterion methods include densitometry (underwater weighing), computed X-ray tomography (CT), magnetic resonance imaging (MRI), and DXA (Martini&Nath, 2009). These …show more content…

However, there is no single universally recommended method for body composition assessment. Criterion methods include densitometry (underwater weighing), computed X-ray tomography (CT), magnetic resonance imaging (MRI), and DXA (Martini & Nath, 2009). These methods are in most instances not suitable for assessing body composition at the community level as they are not cost effective and time consuming. Indirect methods, including anthropometry (weight, stature, abdominal circumference, and skinfold measurements, BMI, waist-hip-ratio) and bioelectrical impedance analysis (BIA), provide estimates or indices of body composition mass and fat mass by measuring the resistance of the body as a conductor of a very small electrical current. These indirect methods are relative cheap and easy to implement at community level (Tanamas, …show more content…

As a result, indirect methods tend to have larger prognostic errors than direct methods and are affected by sample specificity and disease conditions.

Body Mass Index (BMI) is a measure of body composition. BMI is calculated by taking a person's weight and dividing by their height squared. BMI is an indicator of excessive fatness as well as an indicator of whether the individuals is underweight, it is not necessarily an accurate indicator in all individuals such as muscular individuals, elderly or pregnant women.(Vazquez, 2007)

Waist circumference (WC) is a measurement taken around the abdominal at the level of the umbilicus. Health care professionals use this as an indicator of obese as well as health relate problems. WC on its own cannot determine your medical condition but helps identify where excessive fat is locate. (Vieira,

Recommendations • Continuous patient education should be incorporated in to clinical activities at all clinic locations. This is to enlighten patients on the activities that can adversely affect the accuracy of body composition estimation, when carried out just before visit to the clinics. This will help in maintaining industrial standard. • Specialists taking the body composition estimation should be trained on the importance of adhering strictly to the acceptable protocols of patients check-in and preparation for body composition estimation.

The demographic variables that were measured at the nominal level of measurement were non-drinker, non-smoker, regular exercise, and history of fracture. Nominal data is information that contain two or more categories, however there is no numerical ordering in the values. 2. What statistics were calculated to describe body mass index (BMI) in this study? Were these appropriate?

I can work, travel, study, play, and do almost everything (Clarification). I have perfect weight and a good height (Subordinate Idea). My weight is one hundred and ten pounds, and my height is five feet, four inches. Therefore, I have an ideal Body Mass Index, which is eighteen point eighty-eight. I’m neither obese nor skinny.

The study that we found observed the same variables of body composition as we did. They observed arm mass, trunk mass, and total lean, just to name a few. Their participants also performed at least 2 scans, which is similar to our project. However, they did 3 scans in 1 day, and the participants were fasted before they arrived for his or her scan, and they consumed a meal before each of their participant’s last scan. In our study since we were working with a college aged population, and they would be walking from various places around campus to come to the exercise physiology lab, we decided to have them rest for 5 minutes before getting an analyzation of their body composition.

For men, the test will show 7% of their fat, and for women, it will show 12% (KCII 2). Men and women are known to have very different builds across the body and the ways it's formed. A female wrestler from Coppell High School in Texas states that “losing weight is much harder for girls than boys, since a female body reacts differently to weight deficits at different times, sometimes even putting on extra weight as padding” (CSM). There is a big difference between cutting weight and losing weight. The health aspect of it, when you are losing weight you are gradually losing weight but when you are cutting weight you are unhealthy trying to drop weight in a short amount of

The reason for this is that fact that my weight is to high for my height. If you look at my BMI you would see that I am over by a lot, but one thing that this assessment does not account for is the fact that I work out every day. Muscle weighs more than fat and usually throws off numbers for

These patients were subjected to anthropometric measurements namely waist hip ratio, weight height, skin fold thickness and Lipid profile was done. Results: Both the groups were matched for age, sex and risk factors other than the one studied, namely smoking, alcoholism, diabetes, hypertension, family H/o. There is no statistical difference is noted between the two groups in age, sex, smoking, alcoholism, Hypertension, Diabetes, Family H/o. In all these parameters compared between these groups the P value is more than 0.05 which is statistically insignificant. Conclusion: BMI does not properly define obesity and the risk of cardiovascular events.

Obesity can be simply be defined as too much body fat, or having a body mass index of 30 or higher. Body mass index is a calculation of weight in kilograms divided by the square height in meters, and is a universal screening tool for overweight or obesity (“Defining Adult Overweight and Obesity”). Years ago the BMI scale consisted of three categories: underweight, normal or healthy, and obese. Obesity rates have increased so rapidly that the obesity category had to be expanded. The obese category now consists of obese, severely obese, morbidly obese, and super obese.

Obesity involves excessive weight gain and an abnormal fat accumulation, usually 20 percent or more over an individual's ideal body weight. Humans take in energy from food and drinks, which is used for the body's natural processes and for physical activity. People gain weight if they take in more energy than they use and lose weight if they take in less energy than they use. Excess energy is stored mostly as body fat, laid down at various sites around the body, regardless of whether the excess energy comes from carbohydrates, fats, or proteins, or from alcoholic drinks. As obesity has become a major health problem in the United States, bariatrics become a separate medical branch of medicine that deals with the study, treatment of obesity

BMI or body mass index is a number that is generated by dividing one’s weight in kilograms by the square of one’s height in meters. However when BMI or Body Mass Index is calculated it does not take in the factor of muscles which are much heavier than fat. So although the way BMI is calculated is faulty these rates are very severe. The increase in obesity is mostly due to increased calorie consumption. When a certain person eats more calories than he or she can burn

I. Body Composition Basal metabolic rate (BMR) is the energy needed to fuel basic activities in my body. Based on the result of my body composition analysis, my BMR is 5347kJ or 1278 kcal. The result is also seen using Harris and Benedict equation as it shows that my basal energy expenditure is 1372.144 kcal, which is a close estimation to the acquired measurement. Using my BMR measurement, the total daily calories that I need is 1,757.25 Calories (BMR * 1.375). Lean Body Mass (LBM) or Fat Free Mass (FFM) is the measurement of the body components except fats.

Body Mass Index Elderly differs with living environment, food intake and dietary patterns. When considering the BMI standards of world health organisation, 68 per cent elderly had a normal BMI, which was higher among male elderly (74 per cent). About 37 per cent female elderly were suffering from overweight or obese compared to 14 per cent male elderly. Thus female elderly were vulnerable with overweight or obese while male elderly were at risk with underweight.
