RESUMO

INTRODUCTION: The prevalence of malnutrition in hospitalized children is high and is associated with negative health impact. The aim of this study was to characterize the nutritional status of hospitalized children as well as comparing nutritional risk stratification using the STRONGkids® tool and anthropometric assessment. MATERIAL AND METHODS: A prospective study was conducted between March and June 2019 in a paediatric unit of a district hospital. Children with ages between one month and 17 years were included. Nutritional screening (STRONGkids®) was performed, and demographic and anthropometric variables were assessed by trained doctors and nurses (z-scores for height-for-age, weight-for-age, weight-for-height and body mass index were compared to the World Health Organization reference values) and related to the underlying condition (cause of hospitalization; hospital stay; the presence of chronic disease). RESULTS: A total of 209 children were evaluated, 188 of whom were included. Median age was 4.6 years and median hospital length of stay was four days. Fifty-four per cent were classified with "moderate risk" and 2% with "high risk" of developing malnutrition; 25% were effectively malnourished. Of the 105 children for which it was possible to calculate the z-scores, 6% presented acute malnutrition and nearly 14% presented chronic malnutrition. The STRONGkids® score correlated positively with nutritional status on admission, disease type on admission, and presence of previous underlying disease (p < 0.05). CONCLUSION: STRONGkids® is a simple, quick nutritional screening tool for hospitalized children that is related to nutritional status on admission. Given that a considerably high percentage of children were identified as being at risk for malnutrition, it is essential to identify this early and provide nutritional intervention during hospitalization.

RESUMO

OBJECTIVES: To a) demonstrate that adopting 'at risk' waist-to-height ratio (WHTR) cut-off points, recently approved by National Institute for Health and Care Excellence (NICE) and the United States Department of Defense (USDoD), will unfairly penalize shorter individuals and will be too lenient for taller individuals, b) to confirm that waist circumference (WC) of a sample of US service personnel, scales to approximately height0.5, supporting the notion that WC, to be independent of height (HT), should be normalized using WC.HT-0.5 (WHT•5R), and c) to identify the WHT•5R cut-off points that will reduce or eliminate this unwanted bias. SUBJECTS/METHODS: We employed a three independent cross-sectional sample design. All n = 58,742 participants underwent anthropometric assessment of body mass, stature and waist circumference. RESULTS: The allometric power-law model WC=a.HT^b for US service personnel identified the height exponent to be b= 0.418 (95 % CI 0.251-0.585), confirming that the simple body-shape index for WC to be independent of HT, should be WC.HT-0.5. Chi-square tests of independence and for linear trend confirmed that by adopting WHTR cut-off point, shorter individuals (both service personnel and non-service participants) will be over penalized (classified as being 'at risk'). New WC independent-of-height ratio cut-off points were found to resolve this problem. CONCLUSIONS: Adopting WHTR cut-off thresholds (either 0.5 or 0.55) will lead to shorter adults being unfairly classified as being 'at risk' in terms of their central adiposity and general health status. Adopting new WHT•5R cut-off point thresholds were found to greatly reduce or eliminate this bias.

RESUMO

Digital anthropometry (DA) has been recently developed for body composition evaluation and for postural analysis. The aims of this review are to examine the current state of DA technology, as well as to verify the methods for identifying the best technology to be used in the field of DA by evaluating the reliability and accuracy of the available technologies on the market, and lay the groundwork for future technological developments. A literature search was performed and 28 studies met the inclusion criteria. The reliability and accuracy of DA was high in most studies, especially in the assessment of patients with obesity, although they varied according to the technology used; a good correlation was found between DA and conventional anthropometry (CA) and body composition estimates. DA is less time-consuming and less expensive and could be used as a screening tool before more expensive imaging techniques or as an alternative to other less affordable techniques. At present, DA could be useful in clinical practice, but the heterogeneity of the available studies (different devices used, laser technologies, population examined, etc.) necessitates caution in the interpretation of the obtained results. Furthermore, the need to develop integrated technologies for analyzing body composition according to multi-compartmental models is increasingly evident.

RESUMO

The consequences for adolescent health due to early life exposure to natural disasters combined with war are not known. We collected data from adolescents aged 12-13 years in Sri Lanka whose mothers were pregnant during the Indian Ocean tsunami in 2004 in a tsunami-affected region (n = 22), conflict-affected region (n = 35), conflict-plus-tsunami-affected region (n = 29), or controls in areas unaffected by either (n = 24). Adjusted BMI-for-age z-scores were 1.3 (95% confidence interval [CI] 0.4, 2.2), 1.0 (95% CI 0.2, 1.9), and 2.0 (95% CI 1.1, 2.9) for conflict, tsunami, and conflict-plus-tsunami, respectively, compared with the control group. Greater skinfold thickness and higher diastolic blood pressure were found in adolescents born in the conflict zone but no differences were found in height, head circumference, and waist circumference, or blood results, with the exception of serum insulin. Being born after a natural disaster or during conflict was associated with increased adolescent BMI and body fat, which are associated with longer-term risk of noncommunicable disease.

RESUMO

BACKGROUND: Fluid overload is associated with morbidity and mortality in children receiving dialysis. Accurate clinical assessment is difficult, and using deuterium oxide (D2O) to measure total body water (TBW) is impractical. We investigated the use of ultrasound (US), bioimpedance spectroscopy (BIS), and anthropometry to assess fluid removal in children receiving maintenance hemodialysis (HD). METHODS: Participants completed US, BIS, and anthropometry immediately before and 1-2 h after HD for up to five sessions. US measured inferior vena cava (IVC) diameter, lung B-lines, muscle elastography, and dermal thickness. BIS measured the volume of extracellular (ECF) and intracellular (ICF) fluid. Anthropometry included mid-upper arm, calf and ankle circumferences, and triceps skinfold thickness. D2O was performed once pre-HD. We assessed the change in study measures pre- versus post-HD, and the correlation of change in study measures with percent change in body weight (%∆BW). We also assessed the agreement between TBW measured by BIS and D2O. RESULTS: Eight participants aged 3.4-18.5 years were enrolled. Comparison of pre- and post-HD measures showed significant decrease in IVC diameters, lung B-lines, dermal thickness, BIS %ECF, mid-upper arm circumference, ankle, and calf circumference. Repeated measures correlation showed significant relationships between %∆BW and changes in BIS ECF (rrm =0.51, 95% CI 0.04, 0.80) and calf circumference (rrm=0.80, 95% CI 0.51, 0.92). BIS TBW correlated with D2O TBW but overestimated TBW by 2.2 L (95% LOA, -4.75 to 0.42). CONCLUSION: BIS and calf circumference may be helpful to assess changes in fluid status in children receiving maintenance HD. IVC diameter, lung B-lines and dermal thickness are potential candidates for future studies.

RESUMO

Automated visual anthropometrics produced by mobile applications are accessible and cost-effective with the potential to assess clinically relevant anthropometrics without a trained technician present. Thus, the aim of this study was to evaluate the precision and agreement of smartphone-based automated anthropometrics against reference tape measurements. Waist and hip circumference (WC; HC), waist-to-hip ratio (WHR), and waist-to-height ratio (W:HT), were collected from 115 participants (69 F) using a tape measure and two smartphone applications (MeThreeSixty®, myBVI®) across multiple smartphone types. Precision metrics were used to assess test-retest precision of the automated measures. Agreement between the circumferences produced by each mobile application and the reference were assessed using equivalence testing and other validity metrics. All mobile applications across smartphone types produced reliable estimates for each variable with ICCs ≥0.93 (all p<0.001) and RMS-%CV between 0.5%-2.5%. PE for WC and HC were between 0.5cm-1.9cm. WC, HC, and W:HT estimates produced by each mobile application demonstrated equivalence with the reference tape measurements using 5% equivalence regions. Mean differences via paired t-tests were significant for all variables across each mobile application (all p<0.050) showing slight underestimation for WC and slight overestimation for HC which resulted in a lack of equivalence for WHR compared to the reference tape measure. Overall, the results of our study support the use of WC and HC estimates produced from automated mobile applications, but also demonstrates the importance of accurate automation for WC and HC estimates given their influence on other anthropometric assessments and clinical health markers.

RESUMO

INTRODUCTION: Questions continue to be raised about the validity that is in existence to estimate Db, in professional male footballer players. METHODS: Phase 1: n = 28 anthropometric variables were used on n = 206 footballers, using regression analyses to determine standard error of estimate and R2. A cut-off correlation coefficient set at r = 0.950 and 90% R2. Phase 2: all variables (z-scores, x- = 0.0, SD = ±1.0) to help reduce heteroscedasticity, ß, r, t, significance of t and P-values were calculated. Phase 3: a forced stepwise-backwards regression analysis approach with nine predictors which met the acceptance criteria (r = 0.950, R2 = 90% and ß weights) was used to develop a 'best fit' and a 'practical' calibration model. Phase 4: cross-validation of the two newly developed calibration method using LoA. RESULTS: The 'best fit' model SEM (0.115 g ml-1), the highest R2 (6.6%) (P ≤ 0.005), whereas the 'practical' calibration model SEM (0.115 g ml-1), R2 (4.7%) (P ≤ 0.005) with r values = 0.271 and 0.596 and R2 (%) coefficients = 0.3526 for the 'best fit' and 'practical' calibration models, respectively (P = 0.01). CONCLUSIONS: The two calibration models supported an ecologically and statistically valid contribution and can provide sound judgements about professional footballers' body composition.

RESUMO

Smartphone applications (SPA) now offer the ability to provide accessible in-home monitoring of relevant individual health biomarkers. Previous cross-sectional validations of similar technologies have reported acceptable accuracy with high-grade body composition assessments; this research assessed longitudinal agreement of a novel SPA across a self-managed weight loss intervention of 38 participants (21 males, 17 females). Estimations of body mass (BM), body fat percentage (BF%), fat-free mass (FFM), and waist circumference (WC) from the SPA were compared with ground-truth (GT) measures from a dual-energy x-ray absorptiometry scanner and expert technician measurement. Small mean differences (MD) and standard estimate of error (SEE) were observed between method deltas (ΔBM: MD = 0.12 kg, SEE = 2.82 kg; ΔBF%: MD = 0.06 %, SEE = 1.65 %; ΔFFM: MD = 0.17 kg, SEE = 1.65 kg; ΔWC: MD = 1.16 cm, SEE = 2.52 cm). Correlation coefficient concordance (CCC) assessed longitudinal agreement between the SPA and GT methods, with moderate concordance (CCC: 0.55 - 0.73) observed for all measures. The novel SPA may not be interchangeable with high-accuracy medical scanning methods, yet offers significant benefits in cost, accessibility, and user comfort, in conjunction with the ability to monitor body shape and composition estimates over time.

RESUMO

Postmenopausal aging has become relevant for understanding health during the transition life stages-the aging process being involved in several disturbances of the human condition. The present study aimed to investigate the relationship between postmenopausal aging and sociodemographic, anthropometric, body composition, nutritional, and biochemical (i.e., protein and lipid profiles, phosphorous-calcium metabolism, and antioxidant status) factors in postmenopausal women. This cross-sectional study enrolled 78 healthy postmenopausal women (44-76 years). The anthropometrical data showed no differences by age. Biochemical parameters, especially those involved in the protein and phosphorous-calcium metabolism, were influenced by age in our cohort of postmenopausal women. In contrast, no associations were found when considering lipid and antioxidant parameters. Height, fiber intake, blood glucose, protein profile and phosphorous-calcium metabolism markers seem to be the most affected nutritional-related factors by age in our cohort of healthy postmenopausal women. Primary prevention strategies focused on parameters at risk of disruption with postmenopausal aging are necessary to ensure the quality of life in older ages.

RESUMO

Background: /Objectives: The aim of the present study was to analyse possible differences in anthropometric characteristics of elite sailors based on categories and performance level. Methods: ː A total of 42 young (aged 12-18 years) elite sailors (men = 31; women = 11) of the Monohull (n = 21) and Windsurfing (n = 21) categories composed the study sample. Testing was per-formed in one session the day before the start of an official and international competition. Body composition was measured using an octopolar and multi-frequency electrical bioimpedance analyser, and height was recorded using a telescopic measuring instrument. Cross-sectional study. The total sample was divided into two groups based on their performance level (ranking), 50th percentile (P1), and 100th percentile (P2). Results: ː P1 presented a lower BMI, total body fat mass, and body fat mass in the trunk, arms, and legs (p < 0.05). Similarly, P1 reported a higher total body muscle mass and body muscle mass on the trunk, arms, and legs compared to the less level performance group (p < 0.05). In addition, P2 sailors were taller and heavier (p < 0.05). Regarding categories, the Windsurf sailors presented statistically significantly lower arm fat mass than the Monohull (p < 0.05). The Windsurf sailors showed differences between the two performance-level groups (p < 0.05). Additionally, comparing the high-level performance group in both categories, higher arm muscle mass on the Windsurfing sailors was detected (p < 0.05). Conclusions: ː These findings could help to differentiate the anthropometric variables that determine sport performance in young elite sailors and could be used to differentiate the anthropometric variables in each category.

RESUMO

Abstract Objective: To compare the performance of anthropometric indicators that identify excess body fat (BF) in adolescents. Methods: This is a methodological study that used probability cluster sampling through school and class draws. Data collection included sociodemographic characteristics and anthropometric measures. Body mass index (BMI), waist-to-height ratio (WtHR), conicity index (C index), and waist circumference (WC) were calculated. Body fat percentage (BF%) was calculated from skinfold thickness and used as the gold standard. To analyze the data, descriptive statistics, Student's t-test, Receiver Operating Characteristic (ROC) curve, and Youden's index were used, in addition to correlation coefficient calculation between the indicators and BF%. Results: A total of 997 adolescents enrolled in municipal secondary schools participated in the study. By calculating the BMI, we found that 10.6% of adolescents were overweight, and 4.7% were obese. BMI, WC, and WtHR had the highest accuracy to predict body fatness. All the anthropometric indicators had higher specificity than sensitivity to diagnose excess BF in males. WC had the highest sensitivity in both genders. C index had the smallest area under the ROC curve and the lowest sensitivity in both genders, but its specificity was equivalent to that of the other indicators. Conclusions: BMI, WtHR, and WC were the best anthropometric indicators to predict excess BF in adolescents and had the best correlation coefficients. These tools can be considered in the screening to detect excess BF in adolescents.


RESUMO Objetivo: Comparar o desempenho de indicadores antropométricos para identificar o excesso de gordura corporal (GC) em adolescentes. Métodos: Estudo metodológico com amostragem probabilística por conglomerados, por sorteio das escolas e turmas. A coleta de dados incluiu características sociodemográficas e medidas antropométricas. O índice de massa corporal (IMC), a relação cintura-estatura (RCE), o índice de conicidade (IC) e a circunferência da cintura (CC) foram calculados. O percentual de gordura corporal (%GC) foi calculado com base na espessura das dobras cutâneas e utilizado como padrão-ouro. Para analisar os dados, foram utilizadas estatísticas descritivas, teste t de Student, curva Receiver Operating Characteristic (ROC) e índice de Youden. Foi calculado o coeficiente de correlação entre os indicadores e o %GC. Resultados: Participaram do estudo 997 adolescentes de escolas municipais. Identificou-se, pelo IMC, que 10,6% dos adolescentes apresentavam sobrepeso e 4,7%, obesidade. O IMC, a CC e a RCE apresentaram a maior acurácia para predizer a gordura corporal. Todos os indicadores antropométricos apresentaram especificidade superior à sensibilidade para diagnosticar excesso de GC no sexo masculino. A CC apresentou a maior sensibilidade em ambos os sexos. O IC apresentou a menor área sob a curva ROC e a menor sensibilidade em ambos os sexos, mas especificidade equivalente aos demais indicadores. Conclusões: IMC, RCE e CC apresentaram a melhor capacidade de predizer excesso de GC em adolescentes e os melhores coeficientes de correlação. Essas ferramentas podem ser consideradas formas de rastreamento na identificação do excesso de GC em adolescentes.

RESUMO

ABSTRACT Objective The aim of this study was to determine the influence of morphology on karate characteristics and basic motor skills for the criterion variable counter-punch (gyako zuki) in boys, after a two-year training program. Methods A system of 25 variables (12 morphological, 12 motor, and one situational (gyako zuki)) was applied in a sample of 82 karatists, aged 10 to 14 years. Data were processed using regression analysis. Results Body weight had a statistically significant influence on the criterion variable in the initial measurement, as well as on the triceps and back skinfolds in the final measurement. In the motor space, semi-squat endurance had a significant impact on both initial and final measurements. In the reduced system, triple jump, half-squat endurance, and long jump impacted the initial measurement, while the 30-second torso lift, hyperextension on the bench, and semi-squat endurance impacted the final measurement. Conclusion From the data obtained, it can be concluded that the counter-punch (gyako zuki) performance results were better in participants with higher body weight, longer arms, less subcutaneous upper arm and back fat, greater static and explosive power in the lower limbs, and greater hamstring and spine flexibility.

RESUMO

BACKGROUND: Few studies have examined whether gestational exposure to organophosphate esters (OPEs), widely used chemicals with potential endocrine-disrupting potency and developmental toxicity, is associated with impaired infant growth. METHODS: We analyzed data from 329 mother-infant pairs in the Health Outcomes and Measures of the Environment (HOME) Study (2003-2006, Cincinnati, Ohio, USA). We quantified concentrations of four OPE metabolites in maternal urine collected at 16 and 26 weeks of gestation, and at delivery. We calculated z-scores using 2006 World Health Organization (WHO) child growth standards for the 4-week anthropometric measures (weight, length, and head circumference), the ponderal index, and weekly growth rates. We used multiple informant models to examine window-specific associations between individual OPE metabolites and anthropometric outcomes. We further modeled OPEs as a mixture for window-specific associations with 4-week anthropometric outcomes using mean field variational Bayesian inference procedure for lagged kernel machine regression (MFVB-LKMR). We stratified the models by infant sex. RESULTS: Diphenyl phosphate (DPHP) in mothers at 16 weeks, and bis(2-chloroethyl) phosphate (BCEP) and bis(1,3-dichloro-2-propyl) phosphate (BDCIPP) at delivery were positively associated with z-scores of weight, length, and head circumference in all infants at 4 weeks of age. After stratifying by infant sex, positive associations were only observed in males for DPHP at 16 weeks and BCEP at delivery and in females for BDCIPP at delivery. Negative associations not present in all infants were observed in males for di-n-butyl phosphate (DNBP) at 26 weeks of gestation with weight z-score and DPHP at delivery with head circumference z-score. Results were generally similar using MFVB-LKMR models with more conservative 95 % credible intervals. We did not identify consistent associations of gestational OPE metabolite concentrations with the ponderal index and weekly growth rates. CONCLUSION: In this cohort, exposure to OPEs during gestation was associated with altered infant anthropometry at 4 weeks after birth.

RESUMO

Aging is believed to occur across multiple domains, one of which is body composition; however, attempts to integrate it into biological age (BA) have been limited. Here, we consider the sex-dependent role of anthropometry for the prediction of 10-year all-cause mortality using data from 18,794 NHANES participants to generate and validate a new BA metric. Our data-driven approach pointed to sex-specific contributors for BA estimation: WHtR, arm and thigh circumferences for men; weight, WHtR, thigh circumference, subscapular and triceps skinfolds for women. We used these measurements to generate AnthropoAge, which predicted all-cause mortality (AUROC 0.876, 95%CI 0.864-0.887) and cause-specific mortality independently of ethnicity, sex, and comorbidities; AnthropoAge was a better predictor than PhenoAge for cerebrovascular, Alzheimer, and COPD mortality. A metric of age acceleration was also derived and used to assess sexual dimorphisms linked to accelerated aging, where women had an increase in overall body mass plus an important subcutaneous to visceral fat redistribution, and men displayed a marked decrease in fat and muscle mass. Finally, we showed that consideration of multiple BA metrics may identify unique aging trajectories with increased mortality (HR for multidomain acceleration 2.43, 95%CI 2.25-2.62) and comorbidity profiles. A simplified version of AnthropoAge (S-AnthropoAge) was generated using only BMI and WHtR, all results were preserved using this metric. In conclusion, AnthropoAge is a useful proxy of BA that captures cause-specific mortality and sex dimorphisms in body composition, and it could be used for future multidomain assessments of aging to better characterize the heterogeneity of this phenomenon.

RESUMO

OBJECTIVE: To evaluate the accuracy of facial measurements on three-dimensional images obtained using a new photogrammetric scanner. MATERIAL AND METHODS: A total of 11 participants were included in the study. Nine customized adhesive labels were used to identify the facial landmarks: Trichion (Tri), Glabella (G), Right (Exr) and Left (Exl), Pronasal (Pn), Subnasal (Sn), Chelion right (Chr) and left (Chl) and Mentonian (Me). Two trained and calibrated examiners were responsible for performing seven linear measurements for each participant (Tri-G, Sn-Me, Exr-Exl, Chr-Chl, Exr-Chr, Exl-Chl, Pn-Sn) first with a digital caliper and later with a three-dimensional model obtained after digitalization with photogrammetric technology. The intraclass correlation coefficient (ICC), mean difference, SD, and Bland-Altman correlation were used to compare the measurements performed. RESULTS: Intra and inter-examiner reliability were excellent (ICC >0.9). In general, the measurements presented a variation of a minor 2.0 mm. However, only three measures (Sn-Me, Exr-Exl, and Exr-Chr) were outside the clinical acceptability range. CONCLUSIONS: The 3D Cloner scanner showed clinically acceptable accuracy comparable to the digital caliper with a variation of -0.8 ± 1.2 mm. Inter- and intra-examiner agreement on digital measurements was also observed. CLINICAL SIGNIFICANCE: Scanners with accurate 3D model reproductions associated with reliable digital measurements provide a more precise diagnosis and better planning in orofacial treatment.

RESUMO

Gauri KapoorBackground The survival of children with cancer has improved owing to advances in chemotherapy and better supportive care, and nutritional support is an important component of the latter especially in low- and middle-income countries like India. Materials and Methods A prospective observational study of 137 newly diagnosed children with cancer aged less than 18 years was planned. Nutritional assessment was done using dual-energy X-ray absorptiometry (DXA), anthropometry, and serum albumin. Patients were followed for 3 months for assessment of treatment-related morbidity. Results Lean body mass (LBM; DXA), mid-upper arm circumference (MUAC), and body mass index detected undernutrition in 44, 45, and 14% patients, respectively. Combination of arm anthropometry (MUAC and triceps skinfold thickness) with serum albumin categorized patients as adequately nourished (32%), moderately depleted (18%), and severely depleted (49%). Patients with hematological malignancy had a higher prevalence of undernutrition but there was no difference in morbidities between the undernourished and adequately nourished children by any parameter. Hypoalbuminemia observed in 25% patients was associated with significant chemotherapy delays ( p , 0.01) and interval admissions ( p , 0.03). Using LBM as a criterion, linear regression analysis revealed MUAC ( R 2 = 0.681) as the best predictor of undernutrition with lowest standard error. Conclusion Our study reports undernutrition among two-fifths of newly diagnosed patients of childhood cancer associated with high prevalence of sarcopenia and adiposity. These findings are of utmost clinical relevance in planning interventional strategies.

Objective: This study aimed to analyze if anthropometric factors and physical appearance are associated to QoL in Turner syndrome (TS). Materials and methods: Observational, analytical, and cross-sectional study. The SF-36 was applied along with an additional questionnaire regarding specific characteristics of TS. Results: There were no differences in quality of life (QoL) in TS women regarding median height and appropriate height according to parental target height, however, participants satisfied and who did not desire to change their height had better scores in the mental health and role emotional domains than those not satisfied and desired to change it. When comparing participants who were or were not bothered by physical appearance, the results showed that those not bothered by physical appearance had a better score in the vitality and social function domains. Considering patients who did or did not desire to change physical appearance, those who did not want to change their physical appearance had higher scores in the mental component and in the social function and mental health domains of the SF-36. Conclusion: This study indicated that anthropometric factors and physical appearance may possibly be associated to QoL in TS, and also emphasizes the need to develop and validate an official questionnaire regarding specific TS characteristics in order to assess in more detail how specific characteristics of TS interfere with their QoL.

RESUMO

El objetivo de este artículo es aproximarnos a la historia del gabinete antropométrico de la prisión Modelo de Barcelona entre 1895 y 1918. Será revisada la confluencia entre las nociones jurídicas, científicas y religiosas que los agentes correctores de la cárcel introdujeron en el gabinete, así como las discusiones, tensiones e interpretaciones que produjo su práctica. Para llevar a cabo este propósito la investigación girará en torno a las siguientes preguntas ¿cómo se consolidó la antropometría criminal en Barcelona? ¿Cuáles fueron las características de su proceso de apropiación? ¿las posturas vernáculas de los agentes correctores de la Modelo implicaron una transformación en el sistema antropométrico? y ¿cuáles fueron las consideraciones de los presos frente a este saber? Para responder estas preguntas, este artículo problematizará metodológicamente sobre las perspectivas enunciadas, primero, por la prensa local y los escritos de los representantes de la prisión Modelo, desde donde se interseccionó el ideal de prevención y corrección. Además, se hará un acercamiento a las experiencias escritas por los individuos antropometrizados, con las cuales se ofrecerá una constelación de representaciones microhistóricas y regresivas que develarán la criminalización del enemigo político, de las clases subalternas y el funcionamiento mismo del gabinete.(AU)


The aim of this article is to offer an approach to the history of the anthropometric cabinet for criminal identification at the Modelo Prison in Barcelona between 1895 and 1918, reviewing the confluence of legal, scientific and religious notions that prison correctional officers introduced into the cabinet. Based on these considerations, we will ask the following questions: how criminal anthropometry was consolidated in Barcelona? what were the characteristics of its appropriation process? did this imply a process of transformation of anthropometry by the vernacular postures of those who had access to it? and what were the considerations of the prisoners in relation to this knowledge? In order to answer these questions, this article will methodologically problematize around the perspectives enunciated, first, by the local press and the writings of the representatives of the Modelo prison, through which the ideal of prevention and correction was intersected. And secondly, by seeking a reading from the experiences written by anthropometrized individuals, which offers a constellation of representations conducive to discuss the criminalization of the political enemies, the subaltern classes and the operation itself at the cabinet.(AU)

RESUMO

Professional football players are obligated to meet the physical demands and maintain the best possible performance throughout the whole macrocycle. It is important to assess the players' nutrition knowledge, identify areas that require increased nutrition awareness and identify the impact of knowledge on changes in body composition as this can affect the players' health and performance. This study aimed to assess changes in the body composition of professional football players during the macrocycle of the spring round of the football championship and to identify the correlation between nutrition knowledge and maintaining body composition. The study included 38 football players. The players' body compositions were analyzed 6 times during the macrocycle consisting of preparatory, competitive, and transition periods using the Direct Segmental Multi-Frequency Bioelectrical Impedance Analysis method. Athletes completed the Nutrition for Sport Knowledge Questionnaire to assess their nutrition knowledge. During the preparatory period, a statistically significant negative correlation was demonstrated between the players' knowledge about the subsections of micronutrients in the diet and the dispersion of the adipose percentage tissue content (r = -0.36, p = 0.03). In the competitive period, there was a statistically significant negative correlation between the players' knowledge of sports nutrition and the dispersion of lean body mass (r = -0.46, p = 0.004), and skeletal muscle mass (r = -0.36, p = 0.03). During the transition period, a statistically significant negative correlation between the players' knowledge of weight control and the dispersion of body mass (r = -0.47, p = 0.00) and BMI values (r = -0.48, p = 0.00) was identified. The player's knowledge about the subsection of macronutrients significantly negatively correlated with the dispersion of skeletal muscle mass content (r = -0.33, p = 0.05). Nutrition knowledge has an impact on the stability of body composition during all analyzed periods: preparatory, competitive, and transition periods.

RESUMO

Background. Establishing an accurate occlusal vertical dimension (OVD) is a crucial clinical step during full-mouth rehabilitation. Various techniques have been suggested to evaluate OVD, but none of them is practically reliable, and each one has its shortcomings. The correlation between facial proportions and the lower third of the face is a reliable method but needs to be verified in many ethnic groups. Therefore, this study aimed to determine the correlation between OVD and various facial measurements in a Tunisian ethnic group. Methods. A cross-sectional study was conducted between November 2020 to January 2021. The participants were randomly selected from dental students, dental surgeons, and the patients referring to the University Dental Clinic for dental treatments. Seven facial measurements were clinically recorded using a digital caliper. The correlation between OVD and facial measurements was analyzed using Spearman's coefficient and linear regression analysis. Results. A total of 201 dentate participants (134 females and 67 males) were included in the study. The mean OVD in male subjects was higher (67.60±4.49) compared to female subjects (60.72±3.84). The total facial height was positively correlated with OVD in both genders. OVD was statistically correlated with the height of the upper lip. This correlation was highly significant in males while it was weak in the female group. Conclusion. Facial proportions and linear equations are non-invasive, simple, and reliable methods to predict OVD, especially in males.
