The Relationship Between Nephrolithiasis Risk with Body Fat Measured by Body Composition Analyzer in Obese Peopale

Background:The purpose of this study was to assess the relationship between intensity of physical activity (PA) and body composition in 343 young women.Methods:Physical activity was objectively measured using accelerometers worn for 7 days in women 17 to 25 years. Body composition was assessed using the BOD POD.Results:Young women who spent less than 30 minutes a week performing vigorous PA had significantly higher body fat percentages than women who performed more than 30 minutes of vigorous PA per week (F = 4.54, P = .0113). Young women who spent less than 30 minutes per day in moderate to vigorous PA (MVPA) had significantly higher body fat percentages than those who obtained more than 30 minutes per day of MVPA (F = 7.47, P = .0066). Accumulating more than 90 minutes of MVPA per day was associated with the lowest percent body fat. For every 10 minutes spent in MVPA per day, the odds of having a body fat percentage above 32% decreased by 29% (P = .0002).Conclusion:Vigorous PA and MVPA are associated with lower adiposity. Young women should be encouraged to accumulate at least 30 minutes of MVPA per day, however getting more than 90 minutes a day is predictive of even lower levels of adiposity.

The Relationship

To study the relationship between health and nutritional status in elderly populations, information about body composition is essential. To collect this information in large epidemiological studies, practical methods based on anthropometric data must be available. In the present study the relationship between body composition, determined by densitometry, and anthropometric data in 204 elderly men and women, aged 60–87 years, was analysed. Existing prediction equations described in the literature, and mainly based on young and middle-aged subjects, generally underestimated percentage body fat in the elderly study population. Therefore, new prediction equations were developed, based on sex and the sum of two (biceps and triceps) or four (biceps, triceps, suprailiaca and subscapula) skinfolds or the body mass index (BMI). Addition of age or body circumferences to the models did not improve the prediction of body density. Internal cross validation and external validation revealed that the formulas are valid for the estimation of body density in elderly subjects. The standard errors of estimate of the three models, expressed as percentage body fat, were 5.6, 5.4 and 4.8% respectively.

The Relationship

Overweight and obesity in Asian children are increasing at an alarming rate; therefore a better understanding of the relationship between BMI and percentage body fat (%BF) in this population is important. A total of 1039 children aged 8–10 years, encompassing a wide BMI range, were recruited from China, Lebanon, Malaysia, The Philippines and Thailand. Body composition was determined using the 2H dilution technique to quantify total body water and subsequently fat mass, fat-free mass and %BF. Ethnic differences in the BMI–%BF relationship were found; for example, %BF in Filipino boys was approximately 2 % lower than in their Thai and Malay counterparts. In contrast, Thai girls had approximately 2·0 % higher %BF values than in their Chinese, Lebanese, Filipino and Malay counterparts at a given BMI. However, the ethnic difference in the BMI–%BF relationship varied by BMI. Compared with Caucasian children of the same age, Asian children had 3–6 units lower BMI at a given %BF. Approximately one-third of the obese Asian children (%BF above 25 % for boys and above 30 % for girls) in the study were not identified using the WHO classification and more than half using the International Obesity Task Force classification. Use of the Chinese classification increased the sensitivity. Results confirmed the necessity to consider ethnic differences in body composition when developing BMI cut-points and other obesity criteria in Asian children.

Abstract Introduction: Physical activity is one of the basic elements that affect functional performance and body composition. The age may result in adverse changes in these parameters. The study aimed to compare the functional fitness and body composition in physically active women over 60 years old in different age groups and determine the relationship between those two components. Material and methods: The study participants attended gymnastic classes at the University of Third Age of Warsaw University of Technology. A total of 39 women were examined in three age categories - 60-64 years (13 women), 65-69 years (13 women), 70-74 years (13 women). The study used the Senior Fitness Test (SFT) to assess functional fitness. Body composition was tested using a device Tanita BC 420. Results: Statistical analysis showed no statistically significant (p≤0.05) differences in functional fitness and body composition between women of different age groups. A statistically significant negative correlation was found for Back Scratch test with BMI and percentage of body fat and a positive with muscle mass. Additionally, 8-ft up-and-go test positively correlated with BMI and percentage of body fat and negatively with muscle mass. Conclusions: Regular physical activity allows to maintain the level of functional fitness in older women. Element requiring additional commitment are flexibility exercises. The study confirmed the relationship between body composition and functional fitness of older women.

Background and Aims: The Body Mass Index (BMI) is considered one of the most common indexes for examining the health. The purpose of this study was the design and validation of the equations for the accuracy of BMI. Methods: In the current 419 athletic and non-athletic subjects participated in this study. Anthropometrical measurement was performed using International Standard for Anthropometry and Kinanthropometry (ISAK) protocol, and mesomorphic and endomorphic calculated based on the Heath-Carter methods. The Spearman correlation coefficient was used to determine the relationship between BMI and body fat percent, mesomorphic and endomorphic values. Multiple regressions were used to predict BMI. Results: There is a high correlation between BMI with mesomorphic and endomorphic values (P<0.01), but the correlation of BMI with mesomorphic in athletic men was higher than endomorphic (0.77 vs. 0.63). Multiple regression produces some equations for predicting mesomorphic and endomorphic, and bland Altman believes that all equations predict fatness. Conclusion: According to the results, the Equations proposed in this study could appropriately turn BMI to predict body composition so that this equation could determine higher BMI because of the higher muscular mass.

Background:The aim of this study was to investigate the relationship between steps per day and adiposity among college women.Methods:This study was cross-sectional and included women ages 18–25. Participants wore a pedometer for 7 consecutive days. Body composition was assessed using air-displacement plethysmography. Height, weight, and waist and hip circumferences were assessed.Results:The women took 10,119 ± 2836 steps per day. When divided into quartiles by steps, the top 2 quartiles of women in the study had significantly lower BMI, percent body fat, and waist and hip circumferences than the bottom quartile of women (P ≤ .05). Percent body fat was different between the bottom 2 quartiles and the top 2 quartiles (P ≤ .05). The odds of having a body fat of greater than 32% were reduced by 21.9% for every increase of 1,000 steps taken per day (P ≤ .05).Conclusions:Steps per day are related to body composition in young adult women, but this relationship weakens with progressively higher step counts. A reasonable recommendation for steps in young adult women that is associated with the lowest BMIs and body fat seems to be between 10,000–12,000 steps per day.

The Relationship

Body composition was measured in nine healthy, normal-weight, weight-stable subjects in three different research centres. In each centre the usual procedures for the measurements were followed. It revealed that the measurement procedures in the three centres were comparable. Body composition was measured in each centre between 09.00 and 13.00 hours after a light breakfast by densitometry (underwater weighing) and bio-electrical impedance. A single, total-body-water determination by D2O dilution was used as a reference value. Body fat determined by densitometry was significantly lower in one centre, which, however, could be completely explained by a lower body weight, probably due to water loss (the subjects refrained for a longer time from food and drinks before the measurements in that centre) and, thus, by violation of the assumptions of Siri's (1961) formula. Also, body impedance was slightly higher in that centre, indicating a lower amount of body water. Mean body fat from densitometry was also slightly lower in that centre compared with body fat determined by D2O dilution. Individual differences between body fat from densitometry and from total body water were relatively large, up to 7% body fat. The relationship between fat-free mass from densitometry and bio-electrical impedance was not different between the centres. It is concluded that differences in the relationship between body composition and bio-electrical impedance, as reported in the literature, may be due to differences in standardization procedures and/or differences in reference population.

The Relationship

The objective of the present study was to examine the relationship between body composition and blood pressure (BP) in Bahraini adolescents. A sample of 504 Bahraini schoolchildren aged 12–17 years (249 boys and 255 girls) was selected using a multi-stage stratified sampling procedure. BP measurements were performed on the students. Anthropometric data including weight, height, waist circumference (WC), hip circumference, and triceps, subscapular and medial calf skinfold thicknesses were also collected. BMI, percentage body fat, waist:hip (WHR), and subscapular:triceps skinfold ratio were calculated. Mean systolic BP and mean diastolic BP were higher in males than in females. Weight and height in boys and weight only in girls were significantly associated with systolic BP independent of age or percentage fat. Nearly 14% of the adolescents were classified as having high BP. BMI and percentage body fat were significantly and positively associated with the risk of having high BP in the boys and girls. Adolescents with high WHR or WC, as indicators for central obesity, tended to have higher BP values. The results from the present study indicate that obesity influences the BP of Bahraini adolescents and that simple anthropometric measurements such as WHR and WC are useful in identifying children at risk of developing high BP. These findings together with the known tracking of BP from adolescence into adulthood underline the importance of establishing intervention programmes in order to prevent the development of childhood and adolescent obesity.

The Relationship

Aim: Body composition, especially the mass of adipose tissue, affects the risk of developing the metabolic and cardiovascular diseases as well as some cancers. The aim of this study was to determine the relationship between the body composition of adults and their Body Mass Index. Material/Methods: The study involved 120 subjects (69 women and 51 men) aged 19 – 66 (30.55 ± 10.41). The recruited subjects were assigned to three subgroups: with normal body weight, overweight and obesity, depending on the BMI value. There were 40 subjects in each subgroup, including 23 women and 17 men. Besides the measurements of height and body mass, the SECA mBCA515 analyser was applied for the body composition analysis using the bioelectric impedance method. Results: A significant association was found between the BMI index and fat mass, lean mass and muscle mass, both in the whole group and after taking into account the sex. The correlation coefficient R range was from –0.88 to 0.97. The incidence of obesity in the studied group according to body fat content criteria (>25% for men and >30% for women) was 57%, while according to BMI criteria –33%. BMI cut-off points for obesity were 27.8, 26.4 and 26.4 kg/m2 for men, women and for all, respectively. Conclusions: In epidemiological studies, to identify obese people, body fat should also be taken into account in addition to BMI. If obesity is understood as excess fat, and not excess weight, the cut-off points for BMI-based obesity should be lowered.

The Relationship

In this study, we investigated the relationship between motor competence (MC) and behavioral and health outcomes in youth through its relationship to physical activity (PA) and body composition (in terms of body fat). To date, it is unclear whether these variables reciprocally influence each other over time. We assessed whether and how MC, PA and body composition influence each other across adolescence. In a longitudinal study with 14 months of follow-up, we recruited 166 adolescents aged 12–13 years. We recorded participants’ self-reported PA and body fat percentage and assessed their MC using the Körperkoordinationstest für Kinder (KTK). We used linear mixed models and mediation analyses with crude and adjusted (age, sex, time point) models to examine associations among the selected variables across time. MC showed a bidirectional relationship with both PA ( p < .001) and body fat ( p < .001) in both crude and adjusted models. In addition, MC was a potential mediator (Sobel test = –3.18, p < .001) in the relation between body fat (as predictor) and PA (as outcome) in crude models, but no mediating effect was found in adjusted models. Thus, this study provided longitudinal evidence that MC and PA, as well as MC and body composition, can reciprocally influence each other across adolescence. We recommend the development of MC as a crucial strategy to increase PA engagement and to prevent obesity in youth.
