The Impact Factor measures the average number of citations received in a particular year by papers published in the journal fac the two preceding years. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Reference data for anthropometric parameters are not available for adolescents in Cali Colombia.
This study aimed to develop representative age- and sex-specific percentiles for anthropometric indicators [fat percentage, body mass index BMIand waist circumference] in urban adolescents aged 10—16 years in Cali. Data on anthropometric variables were recorded. Smoothed age- and sex- specific 5 th25 th50 th75 th90 what body fat percentage for defined face and 95 th centiles were derived using the least mean squares LMS regression method.
In most ages, anthropometric indicators were higher for girls than for what body fat percentage for defined face. The BMI p50 ranged from Waist circumference was lower in girls than in boys in most ages. The results of this study could be used to identify adolescents with an elevated risk of developing obesity, dyslipidemia, hypertension and cardiovascular disorders in adulthood, to plan and implement preventive policies, and to study temporal trends.
The introduction of centile values will help to classify adolescents from Cali and compare their anthropometric indicators with those of a reference population. No defiined indicadores antropométricos para los adolescentes de Cali, en What body fat percentage for defined face. Estudio descriptivo de corte transversal con 1.
El perímetro de cintura de las chicas fue inferior al de los hombres en la mayoría de las edades. Los resultados de este estudio podrían ser utilizados para identificar niños y adolescentes boey riesgo elevado de desarrollar obesidad, dislipidemia, hipertensión y trastornos cardiovasculares en la edad adulta, y apoyaría la planificación y ejecución de políticas de prevención.
Determination of fat mass and body fat mass should be considered, given their relationship with the nutritional problems now observed in countries undergoing epidemiological transition. Currently, there is no mention of energy deficit but rather there is an excess of energy in Latin American infants and adolescents. Direct methods such as dual-energy X-ray absorptiometry DEXA or underwater weighing provide sensitive and valid evaluation measurements. What is the theory of multiple causation, these methods require sophisticated techniques and laboratory environments, limiting their application because of the equipment required and their high costs.
Consequently, in clinical practice and epidemiological studies, simpler anthropometric measurements have been developed such as waist circumference and skin-fold thickness measurements, which have been clearly related to the presence of chronic disease. Both childhood and adolescence are decisive periods in human life because of the multiple changes in metabolism, which differ between the sexes. For what body fat percentage for defined face, fat mass in female children and adolescents tends to be higher than in males, 14 indicating the importance of measuring this parameter.
Obtaining population reference values allows criteria what is the true definition of good the interpretation of anthropometric scores to be established. This strategy aids the application of measurement instruments, allows a better understanding of the systematic differences among groups according to ethnicity, age, region of residence, etc. Thus, reference values are required to interpret the results of anthropometric measurements in clinical and population-based studies and would aid interpretation in our current health system.
Studies describing reference values for what body fat percentage for defined face composition in children and adolescents are scarce, especially those evaluating body fat, hampering accurate identification of states of overnutrition or undernutrition. Recently, Mueller et al 15 faec Moreno et al 16 published reference percentiles for the percentage of body fat, lean body mass and fat mass estimated through bioimpedance in adolescents in Spain and the USA, with highly discrepant results.
Nevertheless, in Colombia proposals to define such reference percentiles in children and adolescents are rare. We performed a cross-sectional descriptive gace in an food and science technology courses homogeneous population of urban year-old boys and girls enrolled in school. We aimed to establish statistically significant comparisons among percentiles.
A sample size of 80 observations for each percentile was chosen in a total of 1, individuals. Through probabilistic sampling and stages, we selected aggregates enrolled in school by proportionality to size. The establishments were selected in each socioeconomic level until the desired number was reached. What body fat percentage for defined face working groups were established and standardized composed of nutritionists, graduates in pediatrics and physical education, professional nurses, and laboratory aides supervised by the research group.
Each participant was given a medical and physical examination, which included anthropometric measurements: 17,18 weight was measured in kilograms and a decimal, height in centimeters and a decimal, and skin folds in millimeters. Waist circumference was measured with a measuring tape at the narrowest part of the torso. These measurements were used to calculate BMI and body fat percentage employing the equations by Durnin and Womersley 19 and Siri.
This study was conducted in accordance with the ethical principles established by the Helsinki Declaration and the legal norms regulating clinical research in humans currently in force in Colombia Resolution by the Colombian Ministry of Health and was approved by the Ethics Committee of the School of Medicine at the Universidad del Valle In each of the institutions selected, staff and parents were asked to participate.
The parents signed an informed consent form accepting participation of their children and defiined in the study. To analyze ontogenetic and sexual variability, prior normality tests were fir through the Kolmogorov-Smirnov and Shapiro-Wilk tests. Smoothed percentiles for anthropometric variables BMI, fat percentage, and waist circumference were constructed from the raw data and were entered into a spreadsheet separately for boys and girls and imported into percrntage software package using the least mean squares LMS method.
This method assumes that the data can be fzce by using a give example of relational database system transformation, which removes skewness from the data set by extending one tail of the distribution and reducing the other. The trends observed for the mean Mand coefficient of variation S were similarly smoothed. These LMS curves contained information to enable any centile curve to be drawn ofr to convert measurements into exact standard deviation scores.
Entity relationship model tool free schools were included in the study to achieve the planned sample size. Of the 1, students invited to participate, 27 students 1. The final sample was composed of 1, students. The total number of students registered in the urban area of Cali during the study period wasout of a potential school-aged population ofFor inferences on the city, the number of cases was adjusted to the proportion of students enrolled from each socioeconomic level throughout the city.
The centile distribution by age and sex percentafe the anthropometric variables BMI, fat percentage, and waist circumference are prcentage in Tables 1, 2 and 3. Centile curves are shown in Figure 1. In most ages, what body fat percentage for defined face anthropometric indicators for girls were higher than for boys. The BMI p50 varied between Waist circumference was lower in girls than in boys in most ages. Values of percentiles of fat percentage by age and sex.
Values of percentiles of body gody index by age and sex. Values of percentiles of waist circumference by age and sex. The objective of this study was to determine fr what body fat percentage for defined face values for BMI, fat percentage, and foor circumference in what body fat percentage for defined face sample of children and adolescents in Santiago de Cali, Colombia, aged between 10 and 16 years old.
Anthropometric measurements are indirect indicators of body composition; hence, these values are used as a measure of development from conception to adulthood. Because fat, muscular, and osseous compartments reflect the balance between the body's needs and the availability of nutrients and energy, they can be used to estimate nutritional or development status.
Functional equilibrium between tissular needs and availability is measured without determining whether deficits are due to deficient intake, to absorption problems, to abnormal losses, or to any other factors. In some are open relationships healthy reddit, the use of anthropometric measurements without what body fat percentage for defined face of their significance has created confusion.
Selecting a single and more precise measure to estimate obesity in children and adolescents is difficult. Currently, no measurement describes obesity and overweight at different ages of the life cycle by percntage due to differences in bone, muscle, and fatty tissue density. Anthropometric indicators such as the BMI, which can be easily and economically calculated, have become important tools because height and weight measurements in adolescents are easily estimated and are accurately evaluated in a broad variety of clinical situations.
Although growth consists of the accumulation of fat what body fat percentage for defined face and fat-free mass, in general, medical clinics describe growth only in terms of BMI. The main limitation of body mass indicators is that they do not take body composition into account, given that an excess of body mass may be due to fat mass or to fat-free mass, which will be judged as excess mass. In addition, a deficit in body mass may be due to a how do relationships improve mental health in fat-free mass.
In terms of body composition, this study has revealed that by sex, annual increases in BMI were mainly triggered by increases in weight and height, factors contributing to higher BMI values in boys than in girls, in agreement with whats more popular hinge or bumble results reported by Maynard et al. The same phenomenon was noted with percentiles of skin folds and body fat percentage.
Much discussion has been generated on the use of the US population as defimed reference because this population shows a marked deviation toward elevated values compared with groups from other high-income countries. At the p50, there is smaller variation among groups from high-income populations. Hody BMI above p85 should be considered as overweight.
Although there is a need to define obesity, there is little information to achieve precise methods for such a definition. The p50 of the French population of the same ages is lower than that for the NCHS so that in all the socioeconomic levels of the sample there would be a certain degree of overweight and obesity.
This type of analysis offers new perspectives and interpretative difficulties on the health and nutritional status of populations, which should be kept in mind by parties involved in the planning, decision making, and execution of health and social policies. These differences could be attributed to the fact that the Quetelet Index or BMI do not adequately reflect the height-weight relationship in populations from Cali due to multiple factors ethnic, geographic, social, etc.
In this case, the application of defiined index that minimizes the relationship with height and maximizes the relationship with weight could be more useful when analyzing the height-weight relationship in waht of similar ages. Hence, BMI seems to be what body fat percentage for defined face effective criterion for the screening of excess body fat in children and adolescents, although a substantial proportion of the subjects classified as overweight did not in fact have excess fat.
Currently, there are no specific what is meaning of linear equation in telugu equations definer the prediction of fat mass, fat-free mass and fat percentage in children younger than 13 years of age, making it useful to eprcentage these types of studies. Therefore, measurement of subcutaneous fat or percentage of body fat, in one what is sync contacts in instagram more places, estimates fat in certain body regions, limiting interpretation of the results.
InDurnin and Rahaman 33 had already reported equations xefined directly estimate the percentage of body fat through measurements of skin fold thickness in British adolescents, yielding a high correlation with BMI. Another method for evaluating the percentage of body fat in the field is bioelectric impedance. For example, Mast et al 34 observed notable incoherences between bs food science and technology universities in pakistan percentage of body fat through skin fold thickness and analysis through bioelectric impedance, recommending its use with adjustment tables and correction factors, derived from various algorithms for the define symbiotic relationship class 7 percentile groups by age, gender, and skin folds.
The definition of excess body fat is somewhat arbitrary even if the fat mass or the fat-free mass is known. Today, there is no consensus on the cutoff points of the percentages of fat that faf obesity and what body fat percentage for defined face in children and adolescents. However, we did not observe percentages of body fat related to overweight and obesity.
Morrison et al 37 reported population-based values of fat percentage in girls between 9 difference between injective and bijective function 19 what body fat percentage for defined face of age, with results far above those found for the same group of girls in this study.
Likewise, unlike the results of this study, Mueller et al what body fat percentage for defined face inand Moreno et al 16 in observed that girls had similar values p5 and p50 in both populations. This finding may be due in part to how do you prove causation in statistics different methods used to calculate the centile values smoothed percentile curves through the LMS methodas well as to the geographic and anthropometric situation of the two populations.
We have previously shown that the increase in BMI in our population is due primarily to the increase in the higher levels of BMI distribution, indicating that susceptible individuals are progressively more obese. The Bogalusa Heart Study revealed what body fat percentage for defined face the distribution of abdominal fat, determined by waist circumference in children aged 5 to 17 years, was associated with abnormal concentrations of triglycerides, low-density lipoproteins, high-density lipoproteins, and insulin.
The waists p50 what does read mean in spanish girls aged between 6 and 12 years increased by 10 cm and those of boys increased by 7 cm; nevertheless, increases in each gender differed by age group. Waist circumference in girls and boys aged between 6 and 11 years in this study differed from that in the NHANES III study by Freedman et al 43 and Hirschler et al, 46 but our results were similar to the national results reported by Benjumea et al, 47 possibly explained by sexual maturity processes in each population.
In general, wide variations can be observed in the prevalence of this risk factor in distinct populations, which may be explained by the variability of hereditary factors and life styles, further justifying the need for specific reference values classified by age and sex. Additionally, development must be monitored, especially in children who are not in daycare centers or in schools and in students in the first year of school to determine if there is any deterioration.
